Version 4.18.4.0

A major release with many new features and lots of internal changes that should not be visible.

• Le Mans Ultimate added, like the game itself it's Early Access and some features don't work.

• Speech Wizard menu item, designed to make first time set up easier.
  

• Volume control (see menu File/Open data files folder game_volumes.json)
• Audio ducking - drop the game volume while CC is playing sounds
  
• Voice commands to change volume of game and VOIP app
  

• Auto start
• If the Property Enable game auto detect is checked then Crew Chief will switch to the game automatically when the game starts up

• Speech Recognition Improvements

Properties have been added that allow the user to disable all unused speech commands, improving the recognition accuracy for commands that you actually use, see:
- Identify opponents by driver name
- Identify opponents by race position
- Identify opponents by relative race position
to disable some of the worst offenders.

It is now possible to remove entries from the speech_recognition_config.txt file, located in the installation directory, improving the recognition accuracy of what remains. Note that if you remove them from this file, but have a user-level file in your documents folder, the commands will continue to be available.

Don't forget to read the FAQ on speech recognition to get the most out of Crew Chief https://mr_belowski.gitlab.io/CrewChiefV4/VoiceRecognition_InstallationTraining.html and in particular do not forget to set these accordingly:
- Prefer Windows speech recogniser
- Speech recognition country
noting that if you need to change the audio input device you will need to use naudio (and likely match the sampling rate to your microphone).

If you still encounter problems, make sure to enable "Write speech recognition debug data" and listen to your WAV recordings to get an understanding of what CrewChief is hearing. If it is loud and clear, that's when it starts to be a recognition problem rather than a hardware setup problem.

If your microphone is too quiet and the Windows mixer is unable to reach the levels you need, consider installing a software booster such as https://sourceforge.net/projects/equalizerapo/

• Experimental Fuel

A new experimental fuel calculator is available for use and has to be enabled via the Property Experimental fuel calculation (otherwise the older algorithm continues to be used).

The new calculator estimates the number of laps for timed races, allowing both kinds of race sessions to share fuel usage data and settings. This becomes even more accurate as the race plays out and the fastest laps of the leaders (including multi-class) are accounted for. If the (existing) "Save pit stop benchmark times to disk" feature is used, the times will be used to greatly improve the accuracy of the estimate, and the amount of fuel that is taken on during the pit benchmarks is taken into account (so you can have benchmarks for a full tank, and each series that you race in, which should be good news for iRacing GT3 drivers who dabble with IMSA and endurance events).

Fuel usage will be persisted between sessions (to fuel_usage.json) to improve the accuracy of the fuel usage estimates, and the "pit window will open" call should arrive earlier and be a lot more accurate than previous. This file can be manually curated (or shared with your team) and will only ever store 5 sessions worth of data for any car / track combination.

The way the new calculator works is that the projected fuel usage per lap is on a sliding scale from the most typical lap through to the most fuel intensive lap, only considering green flag laps. The sliding scale is user selected and can be anywhere from 50% (the "median" fuel usage) to 100% (the lap that used the most fuel). Additional margin is added for ovals, and also for tracks depending on their length (so your margin at the Nordscheifle can be different to Lime Rock).

The new Properties are:
- Experimental fuel calculation
- Experimental fuel percentile
- Experimental fuel extra laps to include for ovals
- Experimental fuel reserve (long)
- Experimental fuel reserve (medium)
- Experimental fuel reserve (short)
which are set to sensible conservative values to begin with.

The margins can be changed dynamically with voice commands
- "play it safe on fuel"
- "roll the dice on fuel"
- "reset the fuel plan"
which will double or half the margin, accordingly. For example, if you have been pack racing and fuel saving (i.e. drafting and not reaching full throttle on the straight) you might want to "play it safe on fuel" and get a little bit more margin for when you are in clean air.

CC reports estimated laps left in timed races.
The focus is shortened to the next pit stop instead of saying  "we estimate 142 laps left" and "we'll need 273 litres of fuel"
[Subtitle] You: how long's left
[Subtitle] Jim: 3:hours 48 minutes to go
[Subtitle] Jim: we estimate 18 laps of fuel left

[Subtitle] You: how's my fuel
[Subtitle] Jim: should be about 17:laps of fuel remaining 2.8 litres per lap
[Subtitle] Jim: and we'll need to stop again to get to the end


Don't forget to "Enable iRacing auto refuelling when entering pit in race" if you want to use CrewChief instead of the iRacing autofueller (which must be disabled), or always ask Jim to refuel you manually using a voice command.
This is obviously a very important feature for many racers, so any feedback is greatly appreciated and it is highly recommended that prior to any races that you enable "Make the trace recording button visible" and click the tick to record all the telemetry from the race so that the CrewChief developers can investigate any problems that you encounter (this typically generates ~50MB of data for an hour long race).

• iRacing Landmarks

Thanks to the team at Garage61 we now have the ability to visualise all the iRacing tracks and are actively seeking contributors to update our database! Please come to the CrewChief discord and ask how you can help out as we have a lot of tracks to add, it requires nothing more than a text editor and a web browser to help.

Some tracks have been updated, most notably all configurations of the Nordschleife, so good luck studying the track map to understand what Jim is saying. If there's an incident in Quiddelbacher Hoehe you know you're in trouble.

• Opponent Information

Jim is now able to tell you about the rating and safety license of drivers around you in iRacing and RaceRoom. He will also keep you informed if the car you are approaching is a lapped car and if the car coming from behind is coming to lap you, long before the blue flags come out. This is especially useful in series that do not use blue flags and Jim will encourage you to let them past.

Jim also got a bit better at closing the radio instead of giving out of date information, if you hear him opening and closing the radio a lot, consider disabling "Enable radio beeps" or asking him how his day is going.

If you want to know what car number your opponents are sporting, make sure to enable "Opponents identified by name and number" which will let Jim know to use their name and number even if he knows their name.

A heuristic reputation system has been added for iRacing, allowing you to agree with Jim how to detect if other drivers might have a less-than-admirable reputation. This is off by default but can be enabled with the following Properties
- Reputation Messages
- Club Reputations
- Rating Reputation
- Tenure Reputation

He's not yet able to recognise Red Bull Liveries, so you're on your own there.

The "Club" is intended to be used as a proxy for network latency so will be heavily dependent on where you are in the world. See https://iracingdata.com/charts/IncidentsPerClub for some interesting statistics. For example if you're in Europe you might want to consider adding "International" to the list and if you're in the US or Australia you might want to consider adding "International" to the list.

The "Rating" is an absolute minimum threshold and although you may be told about a driver's rating in their description, this cuts straight to the chase. It is intended to be used to filter drivers who are *very* far below your level and are likely to cause you harm by being "helpful" instead of predictable.

The "Tenure" is a proxy for how long drivers have been using the service. As a point of reference, drivers with id 980000 started using the service around 3 months ago as this is written (Feb 2024) and this can be moved forward 10000 every month or so to continue using that kind of threshold.

During a race, you can tell Jim to "mark the driver [ahead/behind] as dirty" which will be remembered for following races. If you weren't able to catch the guy that divebombed you from 10 car lengths back, you can always edit the iracing_reputations.json file in your crewchief documents folder, which looks something like this. All fields except customer_id are informational / optional and you can also record carClass and date for posterity.
[
  {
    "customer_id": 408068,
    "name": "Jos Verstappen",
    "comment": "thinks he's Max Verstappen"
  },
  {
    "customer_id": 65874,
    "name": "William Byron",
    "comment": "will never win Daytona racing like this"
  }
]

(lol, this is just an example, we're not suggesting these guys are actually dirty drivers!)

For more real world drivers on iRacing, see https://www.reddit.com/r/iRacing/comments/qym1fo/list_of_real_life_drivers_on_iracing/

"iRacing Strength of Field is for the player class" can be used to avoid noise from other classes when asking what the strength of field is. Unfortunately Jim is yet to record a gridwalk message that we can use, so you have to ask.

• Trainee Crew Chief

You should now see Jerry as an option for both the crew chief and the spotter. However, while Jerry is learning how to be a fully qualified crew chief, we recommend that you only select him as your Spotter, leaving Jim as chief, but then go to the Property Window, find Trainee chief where you can type "Jerry", and restart Crew Chief. You will then sometimes hear Jerry when he has something to say, but you won't miss anything Jim has to say. Jerry has a US accent and you can select Trainee is US only if you only want to hear him when using American units, which can be controlled in the sim (such as iRacing).

• Properties Window

Two new category filters have been added

1. VIPs (Very Important Properties) which is preselected when CC first runs.
2. New Properties in this release
   

• GTR2 plugin updated to v3.3.0.0
  
• Miscellaneous

Some new Properties have been added
- American units for stock car racing
- Time between announcing new opponent (and we're aware of an issue when the car in front is blinking)

and a variety of bugs have been fixed. Most notably, the formation side bug has been fixed in iRacing. Or, rather, has been worked-around. We must now maintain a database of the track formation rules since the iRacing telemetry is buggy. New tracks will be added manually.

New voice commands:
- what's the gap behind on track
- what's the gap ahead on track
- what's the gap to the leader
- what's my car number
- what lap is it
- watch the car ahead
- watch the car behind

and
- pitstop change front tyres only
- pitstop change rear tyres only
now work in iRacing

New menu items
- File/Open data files folder
- File/Open voice files folder

Trace messages in the boot sequence (run CC from the command line:
        CrewChiefV4.exe > output.txt 2>&1
        then output.txt contains the messages which can be used by the dev team)

Write errors to DebugLogs\ErrorLog.txt as well as the console log

Default limit_available_games to all games as a reference for all the names

Upgrade Newtonsoft.Json library to 13.0.3 to get rid of the vulnerability warning (even though it doesn't apply to CC)

• A few minor bug fixes

Version 4.16.1.4

• Added some additional logging for non-standard property values
• Fix some incorrect 'opponent approaching' pit exit calls
• ACC - wait a little longer for stable opponent positions before deriving player grid side and car-to-follow (should fix issues with occasionally incorrect formation lap calls)

• Clear fuel data in race session when starting from the pit lane (should prevent unrealistic fuel consumption figures in such circumstances)
• ACC - improved session restart detection
• ACC - fix cut tracks playing after an invalidated out lap
• ACC - recalculate car to follow and grid side at the start of double-file formation if drivers have dropped out
• ACC - derive the pit window start and end times from the total pit window length, rather than the game-provided start and end times (should fix the incorrect window calls). Note that this may result in incorrect pit window calls if you enter a race session some time after the race has started

Version 4.16.1.2

• Fix issues launching games
• ACC - wired up more pre-start messages and some pit window and session transition fixes

Version 4.16.1.1

• ACC - various improvements to data synchronization and stability work arounds. This should improve the ACC experience significantly
• AMS2 & R3E - open shared memory with read-access only. This should address some startup issues when using the app with other tools that access the games' shared memory files
• GTR2 - plugin update
• ARCA Sim Racing - added basic support for this game using the existing Rfactor1 plugin and classes
• A few minor bug fixes

Version 4.16.0.1

• Change target Dot Net version to 4.7.2. This should have no effect on users, it's required to support new collaborators on the project as the development tooling for the old 4.5 target version is very difficult to find
• AMS2 - updated to latest shared memory version (includes IMO tyre temps and support for extra lap after timed races)
• iRacing - added DRS bleeps (enable with the "Enable DRS beeps" property)
• R3E - fix tyre type mapping for Gr5 cars
• R3E - fix pit menu nagivation (note that this fix is required to keep up with changes to the game, and the 'fix body work' command is no longer available)
• GTR2 - plugin update

Version 4.15.3.12

• Suppress "defend your position" type messages when we have a slowdown penalty
• R3E - fix broken 'request pit' command and a couple of pit menu nagivation issues
• R3E - added repair all and repair none voice commands ('pitstop fix all' / 'box, fix all' / 'pitstop repair all' / 'box, repair all' and 'pitstop fix none' / 'box, fix none' / 'pitstop repair none' / 'box, repair none')

• RF2 - pit menu "refuel to end": don't refuel if enough already
• AMS2 - added repair pit menu macros
• GTR2 - plugin update

Version 4.15.3.10

• Optionally block all complaining and negative messages - to implement this we've updated how we handle the "Max complaints per session" variable. This limits the maximum number of times the app can complain at or make a negative comment to the player in a single session. If you're happy to have the app complain when you do badly (by the app's occasionally unattainable standards) then set this to a higher number. If you don't want the app to complain at all set it to 0. The default value of 60 is intended to prevent the app's grumbling from getting tiresome in endurance or very long races
• Added an option to limit the app's messages to information only ("Disable commentary" property, default false). This setting blocks the app's general 'advice' and encouragement or grumbling messages
• GTR2 - updated plugin

• Content updates for iRacing and R3E
• GTR2: Minor VR improvements
• various bug fixes

• various bug fixes

Version 4.15.3.5

• Fix MS Speech recognition platform download links
• Use 2 decimal places when reporting tyre pressure in kPa
• iRacing - prevent autofuel triggering immediately after a driver swap and when the player isn't driving the car (thanks to Jacob Klein and Doug Evenson for helping track this down)

• A few minor bug fixes

Version 4.15.3.0

• Added a sector 3 pit warning when needing fuel
• Added support for F1 2021 (spotter only, thanks to Christopher Berger)
• R3E - work around the game's pit menu changes. The voice command "fix suspension" should work now but note that it will only toggle the value of this option (the app can't know what it's currently set to)
• GTR2 - update plugin to latest version
• iRacing - fixed macro key presses
• A few minor bug fixes

Version 4.15.2.9

• Tweaked nAudio WASAPI playback to reduce the likelihood of sounds being truncated

• ACC - added "how many laps on tyre set [x]" voice command (reports the number of laps this tyre set has been used for)
• ACC - added "[pitstop / box], select best tyres" voice command - uses the tyre usage data to select the least used tyre set in the pit MFD (just in terms of number of laps)
• ACC - damage threshold tweaks
• R3E - fix some car class handling bugs when server use rolling start qualifying
• A few minor bug fixes

Version 4.15.2.3

• Change all links to thecrewchief.org to use HTTPS
• Added option to disable frozen order (full course yellow / formation lap) messages (property "Enable frozen order messages")
• Fix an app crash when some option files are corrupt or empty
• Some fixes to the macro editor
• ACC - fix some pit menu interactions - the app will always assume that the "Strategy" option is show so you'll need to ensure your current setup has at some pit strategies defined
• R3E - use the tyre temperature ranges sent by the game instead of CC's internal ranges
• GTR2 - added simple flatspot implementation

Version 4.15.2.2

• Updated to include hotfix for macro crash bug
• Added support for Assetto Corsa rally tracks (use Assetto Corsa Rally game option) - puts the app in 'rally mode'
• Added support for modifier keys in macros - prefix the key with modifier+ to hold down that modifier while typing the key (e.g. LSHIFT+KEY_X, RSHIFT+KEY_X, LCONTROL+KEY_X, ALT+KEY_X, etc)
• Added an optional HOLD_TIME modifier to macro keys to specify how long that single key will be held down (e.g. "{HOLD_TIME,4000}KEY_A" hold A down for 4000 milliseconds)
• Added message playback resample option for nAudio - specify a resampling rate in Hz with the "nAudio playback resample rate" property - 0 disables resampling (the default). The sound files are recorded at 22050Hz so there's no point in going above that, values below 5000 may make the messages difficult to understand
• Prevent key bindings activing macros multiple times after restarting the app; Some error logging improvements
• Updated track landmark locations for a couple of tracks (thanks to the users who submitted these)
• Fixed a few bugs and crashes
• RF1 / AMS - experimental implementation of pit box in use warnings (still lots of work and testing to do here, enable this with the "Warn about opponents sharing player's pit box (RF1 / AMS 1 only)" property, note this relies on participants making practice pitstops during practice / qual)
• AC - fixed some incorrect tyre wear thresholds
• ACC - wired up tyre pressure and weather data (including weather forecast data)
• ACC - first cut of a pit menu manager (this will need updated macro definitions, please delete Documents/CrewChiefV4/saved_command_macros.json so the app can recreate it with the required content). The ACC pit menu manager uses cursor (arrow) keys and "P" to navigate the pit menu and can be a bit slow (to reduce the risk of presses being ignored by the game). Supported voice commands include "add fuel, [x] litres", "fuel to the end", "box, change tyres", "box, don't change tyres", "box, wet tyres", "box, dry tyres", "box, tyre set [x]", "box, change [front / rear / left front / right front / left rear / right rear] tyre pressure, [20.3 -> 35]" (note that changing tyre pressures can be a bit hit and miss). In each case the app has to find and change the 'change tyre set' option to work out the menu state - it should revert the change it makes

Version 4.15.1.5

• iRacing crash hotfix

Version 4.15.1.4

• Added option to prefer driver names over car numbers for frozen order calls (full course yellow / rolling start)
• Added suspension velocity histogram data to R3E, AMS2 and pCars2 chart data (default voice command "show me suspension velocity")

• GTR2 - some plugin and VR rendering improvements
• RF2 - some pit menu fixes

Version 4.15.1.1

• Added a configurable delay after releasing the speech recognition button before finishing speech recognition - may help users who tend to release the button too early ('hold button' mode only, property name 'SRE delay after button release')
• Allow keyboard and button assignments to trigger macro functions and extended the Macro Editor UI to support key / button assignments
• Speeded up free-chat macro functions

• GTR2 - VR rendering enhancements and support for more message types including rolling start
• RF2 - pit menu fixes

Version 4.15.0.6

• Some error handling improvements - the app should show a popup window with error details instead of silently crashing and writing to the Windows Event Log
• Command line parameter rework (note that the "RF2_64BIT" parameter has been changed to "RF2")
• iRacing - some car class fixes
• iRacing - fix some issues with off track penalties

Version 4.15.0.5

• GTR2 - fixed missing reflections in VR
• RF2 - pit menu manager improvements
• Minor bugfixes

Version 4.15.0.3

• Some timing accuracy improvements where opponent data is incomplete
• RBR / Dirt / Dirt 2 - ensure corner / obstacle modifiers apply to the correct pace note fragment and fixed issue with pace note corrections not working
• GTR2 - improved plugin handling
• RF2 - pit menu tyre type matching improvements

Version 4.15.0.2

• R3E - hotfix for error when the player has no rating data (i.e. has never raced on one of the official ranked servers)

Version 4.15.0.1

• Added full support for GTR2, see forum post for installation and setup instructions. Note that this also includes full (native) VR support for GTR2 (see the link for details)
• R3E - added rating-based finishing position expectation messages and voice command ("what's my expected finish position?"). The rating data also affects the race-end messages
• RBR / Dirt / Dirt2 - rally stage notes creation improvements - added "into", "and" and "then" items, added "tightens to [1/2/3/4/5/hairpin]" command, ensure pace notes are ordered correctly, some other fixes and improvements
• iRacing - added sanity checks to opponent speed and position data, should reduce the number of spurious stopped-car calls
• Various bug fixes

Version 4.14.0.6

• Fixed 'force single class' option (was being ignored by the app)
• Fix timing issue in multiclass races for some games
• RBR / Dirt Rally / Dirty Rally2 - added 'Minimum rally distance pace note distance (metres)' property to set how far ahead the next pace note needs to be before the app inserts a distance call and 'Dynamic co-driver look ahead distance' property to shorten the look-ahead distance immediately after a slow corner (should reduce call overload into slow corners, disabled by default)
• RBR / Dirt Rally / Dirty Rally2 - added a few more corner / obstacle types ('open hairpin left / right', 'go-straight', 'danger / triple caution' and 'trees / logs / rocks inside / outside') and more corner modifiers ('opens', 'very long' and 'plus / minus') to the rally speech recogniser
• R3E - added "What's the strength of field?" and "What are my incident points?" voice commands
• iRacing - fixed missing meatball flag message
• AMS2 - updated car mappings for new classes
• RF2 - added more tyre types to the pit menu

Version 4.14.0.3

• Changed 'My name' list behaviour - this UI component use to show the specially recorded 'personalisations' (about 1000 names) and all the opponent driver names in the app (about 10000 names), which made it unreliable for some users. By default it now hides the opponent driver names so you'll only see the 1000 specially recorded personalisations. Enabling the "Allow opponent names in 'My name' list" property will add all opponent driver names to this list allowing the app to generate a personalisation from any of the opponent names (see folder C:\Users\[user name]\AppData\Local\CrewChiefV4\sounds\driver_names). Note that these won't sound as natural as the specially recorded personalisations. If you've requested that your name be added to this list, please check again after updating as it might be shown
• AMS2 - added missing car class mappings
• RF2 - fixed tyre selection issues in pit menu manager when selecting some tyre types
• R3E - fixed some missing incident points messages
• RBR - automatically install the Crew Chief plugin
• Various minor bug fixes

Version 4.14.0.2

• Added rally stage notes creation support - see rally pace notes help page
• Added support for Dirt Rally and Dirt Rally 2 (user-created stage notes only)
• Added option to enable scroll bars on main window where necessary (enable with 'Scroll bars on main window' property)
• R3E - use correct field for player incident points
• Pit Manager - tyre selection handles in-game tyre compound that is not in PM's list
• R3E - use correct field for player incident points

Version 4.13.1.7

• Changed "watch" commands to be "monitor" ("monitor [opponent name / the car ahead / p12 / the leader / etc]" / stop monitoring [opponent name / etc] / stop monitoring all etc) - the word "watch" is too similar to "what's" so was being regularly mis-interpreted by the speech recogniser
• Fix some issues with macros not applying to the correct application window
• ACC - fix penalty logic
• ACC - fix for the app repeating laptime in hotstint mode
• RBR - subtitles fix
• R3E - reduced optimial tyre temps for F-Junior

Version 4.13.1.6

• Hotfix for iRacing crash bug (sorry guys)

Version 4.13.1.5

• Added some interpolation for car timing positions - should address issues with wildly inaccurate gap messages where stale data (1 lap old) was being used to calculate gaps
• ACC - fixed player car always being in a separate car class from opponents (should fix at least some of the inaccurate position calls)
• ACC - workaround for unsynchronised lap distance and laps completed data - should greatly improve car position calls in online races

Version 4.13.1.3

• Made splash screen optional
• Some internal sound player wiring fixes
• Don't attempt to show subtitles when there's nothing to show
• Pit Manager "Clear all" clears tyre changes, fuel, any penalties and any damage repairs
• Show separate speech recognition confidence thresholds for Windows and Microsoft speech recognisers on the Properties screen and ensure the thresholds used match the recogniser in use even in cases where the app has to override the user's preferred recogniser. Also added some additional logging to make it clear which recogniser is in use and what confidence thresholds are being applied
• RF2 - Pit Manager changes tyres as part of tyre type commands (so you don't have to make 2 separate commands to change tyre type)
• RF2 - Fix tyre selection on Pit Manager for some cars

Version 4.13.1.2

• Hotfix for startup crash for new users

Version 4.13.1.1

• Added separate voice recognition sensitivity threshold values for when using the built-in Windows speech recogniser. These are higher (particularly for the 'Trigger word') and should stop a lot of the false-positives (again, especially for the 'Trigger word') when using the 'Prefer Windows speech recogniser' option
• Fix z-offset not saving for some VR overlays
• Allow the 'Watch opponent' function to be disabled (added 'Enable watch opponent commands' property, default enabled)
• Fix bug playing start-listening beep using Trigger Word voice recognition mode and nAudio
• Added shortcut key bindings to toggle VR overlays
• Added option to control when subtitles are loaded. If the property 'Lazy load subtitles' is enabled the subtitles are loaded only when needed. This can improve app launch times when using subtitles but may increase app resource use when driving
• R3E - fix for incorrect session length message with time + 1 extra lap race sessions
• iRacing - added Meatball flag message and generic pit-to-serve-penalty message (the app doesn't know if it's a drive-through or a stop-and-go penalty)
• RF2 & RBR - fix app crash when restarting the app

Version 4.13.1.0

• Fixed some cases where the app would use text-to-speech driver names when it shouldn't when the TTS settings was 'Use TTS only when necessary'
• pCars3 - always assume races are single class
• R3E - added support for DTM 2020 rules (push to pass and DRS)
• R3E - added support for minimum pit stop duration (calculates how long you need to wait in the pitbox and warns you about it - note that this calculation requires you to have driven out of the pits at least once since starting the app to record the pit exit position)
• R3E - added support for maximum incident points on ranked servers before being kicked (warnings about further incidents resulting in a DQ / kick)
• R3E - reduced some engine temp warning thresholds
• RF2 - enhanced pit menu manager to support fuel in gallons and some other fixes

Version 4.13.0.2

• VR overlays: Fixed gazing. Added an option to change tracking space for overlays (Seated/Standing/Follow Head)
• Added an option to only use sounds which are gender-neutral. The app has, historically, assumed all players are male so contains lots of sounds with words like words like 'man', 'guy', 'he' etc which is a bit silly. If you enable the 'Block sounds which refer to drivers as male' property the app will only use sounds that are gender-neutral ('driver', 'car', etc). Note that this requires the latest sound pack update to work
• RF2 - tweaked the behaviour of the pit manager system so it only inspects the pit menu layout when it's first invoked, rather than at the start of a session
• RF2 - added an option to disable the pit menu manager ('enable rF2 pit manager' property)
• RF2 - fixed initialisation of pit menu manager

Version 4.13.0.0

• rFactor 2 now needs Vytautas Leonavičius' rFactor 2 Plugin version 3.7.14.2 It's part of this CC version and will be installed automatically but note that any other apps that use it will need to be updated
• Added Rally mode and support for Richard Burns Rally
• Added rudamentary pCars3 support
• Added support for controller 'point of view' buttons (should allow direction-pads to be used for button assignments)
• AMS2 - A few car class tweaks
• ACC - added multi-class support
• RF2 - updated plugin and added a pit menu manager

Version 4.12.0.8

• Corrected VR overlay default behaviour (should fix the remaining issues with the overlays)
• Corrected app name being "5" on the Windows Sounds mixer (stupid fat-fingered typo, sorry)
• Added "what's my oil temp" and "what's my water temp" voice commands
• R3E - tweaked car class mapping for WTCR

Version 4.12.0.7

• Hotfix for issues with VR overlay windows
• Corrected time deltas in multiclass racing on pCars2 / AMS2
• R3E - fixed some missing tyre type mappings

Version 4.12.0.6

• R3E - fixed OtterHud integration

Version 4.12.0.5

• Some UI tidying up and bug fixes
• Stockcar Extreme - fix for app trying (and failing) to install plugin on every start (the plugin .dll must be install manually)
• R3E - download player rating data in background (should improve start up time)
• pCars / pCars2 - allow finer control over car class mapping using an optional pCarsCarNames field in the car classes JSON)
• AMS2 - wired up a bit more of the existing pCars2 logic (e.g. weather conditions)
• Added F1 2020 to games list (spotter only)

Version 4.12.0.1

• Fixed SteamVR detection on non-English installs
• Fixed some issues in speech recognition initialisation error handling
• Fix a crash bug preventing the app from starting when user-defined macros are incomplete
• Allow existing driver name (opponent name) recordings to be used to generate personalisations (note that these may sound a bit robotic - some will probably be fine, some will be unusable, most will be somewhere in between). If you're waiting for your name to be added to the app check the My Name list again - it might be available
• Tweaked the My Name list box so you can now type into it (this is needed because there are now about 8000 entries in this list)
• Added option to force VR overlay windows to be on top
• A few minor bug fixes

Version 4.12.0.0

• Added support for Steam VR overlays. Enable this with the 'Enable VR overlays' property (the app can also start SteamVR if necessary by enabling the 'Start SteamVR if detected' property). This will enable the 'VR Settings' button on the main screen which opens a popup window allowing you to select which of your desktop windows to be rendered in VR. You can also move them around, scale them and other stuff from this menu. This supports any desktop window as well as the Crew Chief overlays (charts, console and subtitles). The app will remember your window config and reapply them when you next start it. If you want the VR overlays to be started with the app, enable the 'Enable VR overlays when app starts' property
• Reworked help and documentation into proper HTML pages accessed from the app's toolbar menu
• Overhauled button handling to reduce delays and fix some issues
• Some pace notes improvements - better multi-lap pace notes handling and add better audio feedback (pace notes specific voice message and a different radio beep when recording mode is enabled)
• Added feature to 'watch' opponents - use the voice command 'watch [opponent last name]', 'team mate [opponent last name]' or 'rival [opponent last name]' to mark a driver as watched. The app will give updates on watched drivers. The watch list can be cleared with the 'cancel watched drivers' command (or 'stop watching [opponent name]' to remove a specific driver). Note that the watch list is cleared on session start so drivers watched in qualifying won't be on the watch list for the race (you need to re-add them)
• R3E - added support for R3E driver rating data. When approaching an opponent with low reputation you may get a warning about him. Opponents' ranking, rating and reputation can be accessed with the voice command 'whats [opponent last name]'s ranking / rating / reputation'
• R3E - updated various vehicle classes and their tyre temperature thresholds and added Daytona track mapping (running on the oval should now activate the oval spotter and logic)
• Various bug fixes

Version 4.11.1.2

• Reworked pace notes functionality to allow pace notes to be recorded over multiple laps and to add some speed and direction filtering (e.g. you might want a particular pace note to only play when the car is going too fast) - full documentation still to be done
• added option to make pace notes play automatically when starting a practice session (disabled by default, enable with 'Play pace notes automatically in practice' property)
• added option to mute other messages when pace notes are playing (enabled by default, disable with 'Mute messages when playing pace notes' property)
• improvements to the subtitle overlay
• replaced existing 'fuel in gallons' property with more generic 'Use metric' property which applies to fuel and speed calls
• added option to disable pit speed limit warnings ('Enable pit speed limit warnings', defaults to enabled)
• iRacing - fix some pitstop commands
• AMS2 - fix command line wiring
• R3E - fix broken opponent position messages when asking "where is [opponent name]"
• R3E - added some missing tyre types to the pit menu code
• R3E - tweaked tyre wear warning messages so the app isn't as conservative
• ACC - fix for broadcast API change

Version 4.11.0.3

• Fix some subtitle issues when using personalisations for some users
• Allow sounds to be played back in stereo when using nAudio for playback (enable with the "Play messages in stereo" property) - should fix cases where the app's sound only plays through one speaker
• ACC - changed deprecation warning so it's just a console message rather than a popup
• Changed default subtitle overlay colour scheme (this can be changed manually by editing the Documents/CrewChiefV4/subtitle_overlay.json file - the recommended value for the "activeColorScheme" property is "CrewChief")

Version 4.11.0.2

• Added subtitles. Subtitles can be shown as an overlay from Crew Chief (enable with the 'Enbable subtitle overlay' option in the Properties screen) or can be written to a shared memory file for use in 3rd party overlays or dashboards (enable with the 'Enable shared memory' option). See sample for an example project which uses this shared memory file. Massive thanks to Nolan Bates for a frankly astonishing amount of work transcribing all of Crew Chief's phrases
• Initial Automobilista 2 support (work in progress). To use this set the Shared Memory mode to Project Cars2 in the in-game System menu
• ACC - removed pit window messages
• ACC - added deprecation warning. We're stopping work on ACC support and might remove support entirely in the future
• various bug fixes and tweaks

Version 4.10.0.9

• Better handling of corrupted settings files on startup
• Improved detection of on-track incidents
• R3E - tweaked suspension damage thresholds
• iRacing - improved session state detection when racing against AI
• iRacing - fix pit limiter warnings

Version 4.10.0.8

• Fixed a couple more start up crashes
• Fix some queuing issues in more complex rally-style pace notes
• RF2 - added Nurburgring corner mappings
• R3E - work around some odd behaviour in the pit menu for races with more than one pitstop
• A few minor tweaks and fixes

Version 4.10.0.6

• Fixed a couple of crash bugs on start up with broken profile settings
• Tweaked pace notes feature to allow a set of sounds to trigger instead of a single sound (to better support complex rally-style pace notes)
• iRacing - some AI session restart logic fixes
• R3E - updated some car class data

Version 4.10.0.5

• Reworked cut track messages to make them more appropriate to how often you cut or violate track limits - note that if you cut persistently and frequently the app will (eventually) start to ignore these cuts
• R3E - auto-select 'serve penalty' in the pit menu when you issue the 'box this lap' command with an outstanding penalty (requires the R3E pit menu key bindings to match the ones the app is expecting)
• R3E - fix crash bug caused by null or empty driver names when sending WebHud data
• iRacing - allow the app to manage disk telemetry handling (enable with 'Enable automatic telemetry disk recording' property)
• iRacing - fix some issues with the track map on chart overlays
• iRacing - improved cut track detection

Version 4.10.0.3

• RF2 plugin hotfix
• Added track map to charts when zoomed in (uses car position data) - visible area is hightlighted in red

Version 4.10.0.2

• Chart controls hotfix

Version 4.10.0.1

• Added overlays for console output and telemetry charts. See Overlays section in Help or Readme, or detailed forum post for more info
• Some audio caching improvments
• some minor tweaks and fixes
• RF2 - new plugin

Version 4.9.11.3

• Hotfix for app startup issues using nAudio where device names aren't unique

Version 4.9.11.1

• Reworked nAudio playback path to improve stability and fix some app shutdown issues; added option to play sounds using WASAPI output device when using nAudio playback (set with the 'nAudio Output Interface Type' property). This has significantly lower playback latency and can make the app sound more natural and responsive - definitely worth trying (remember to enable nAudio playback first). If the audio pops or crackles with this enable try increasing the 'nAudio WASAPI latency' property a bit
• Added option to make the app respond to voice commands as soon as it recognises them in 'Hold Button' mode, rather than waiting until the radio button is released (enable this behaviour with the 'Respond to voice commands immediately' property)
• Allow closing CC from command line by passing C_EXIT command parameter
• ACC - ensure penalties are cleared properly
• AC - some car class tweaks to better map GTE and GT3
• iRacing - more robust pit entry detection (should reduce the likelihood of the all not refuelling after a mess pit entry)
• A few bug fixes

Version 4.9.10.1

• Prevent fuel consumption estimates being skewed by full course yellow flags
• Reworked damage reporting logic to make it more natural
• Some message queuing improvements
• Disable opponent pit exit position estimates during full course yellow flag
• Allow pace notes to play even when the app is in 'keep quiet' mode
• Play a beep when releasing the radio button in 'Hold button' mode (disabled by default, enable with 'enable_on_hold_close_channel_beep' property)
• When spotter messages interrupt the chief or you press the radio button, any sound currently playing is interrupted immediately (only works with nAudio playback enabled and, for voice communication interrupting, 'Block messages when talking to the Chief' enabled)
• Fix 'toggle mode' speech recognition button press issues caused by the app seeing multiple presses when activating speech recognition
• Fix nAudio device indexing when changing default devices
• ACC - added driver stint time messages, more penalty messages and some other missing data
• F1 2019 - use correct property value for UDP port (was using the value for the F1 2018 property)
• R3E - improved detection of hot-lap qualifying sessions to prevent spurious spotter messages
• R3E - fix missing tyre wear messages when multiplier is 2 or more
• R3E - fix incorrect DRS messages

Version 4.9.9.5

• Final hotfix (fingers crossed...) for the remaining speech recognition initialisation issues

Version 4.9.9.3

• Another hotfix (sorry guys) - fix broken speech recognition with non-English versions of Windows, added more sanity checking for user profiles

Version 4.9.9.2

• Hotfix - fall back to Microsoft speech recognition engine implementation if the System speech recognition engine doesn't have the required language support
• Hotfix - fix a crash bug when initialising the speech recognition system for nAudio users
• Hotfix - fix plugin location error

Version 4.9.9.1

• Reworked speech recognisers to allow it to use the built-in Windows speech recognition, which may benefit from being trained to you voice. To enable this, enable the 'Prefer Windows speech recogniser' option in the Properties screen
• Added experimental free-text chat feature for Raceroom, pCars2 and iRacing only - enable with 'Enable free dictation chat messages' property. To use this you must have Windows speech recognition enabled and you'll need to delete Documents\CrewChiefV4\saved_command_macros.json before launching the app (so the app can add a couple of new macro definitions). Read what out you want to say as you would with any other command, starting with "chat" - e.g. "chat, hello everyone" or "chat, this is a test chat message". The app will start the chat by executing the "start chat message" macro which presses C (raceroom) or T (iRacing / pCars2), type in the recognised text after "chat", then end the chat by executing the "end chat message" macro (which just presses enter). Note that this may produce some weird results if the speech recogniser doesn't accurately interpret what you're saying
• Added a voice command to disable most of the complaining messages for the remainder of the current session - "stop complaining" / "stop grumbling" / "f*** off". This will prevent the app berating you when you're doing badly, which may be useful in long sessions
• Limit the number of times the app will complain at the player during a session (default is 50 times, configurable with 'Max complaints per session' property)
• Fixed app crash when using pCars network data button assignments

Version 4.9.8.24

• ACC - fix stale opponents not being cleared from internal state (should fix incorrect incident calls when players disconnect)
• ACC - mapped corner positions for Spa and Barcelona, corrected Monza mapping
• R3E - added missing WTCR 2019 class (this is now correctly grouped with WTCR 2018)

Version 4.9.8.22

• Fix for updates requiring 2 restarts in order to correctly load the user's settings
• ACC - fix various issues including multipler bugs, missing pit exit / entry messages, incorrect mandatory pit stop window messages, missing flag messages, missing track landmark mappings (not every track yet) and a few other bits and bobs
• iRacing - fixed a nasty bug where a particular set of unexpected car class data from the game could make the app unresponsive

Version 4.9.8.20

• Added F1 2019 support (spotter only)
• Added Assetto Corsa Competizioni support. This is a work-in-progress - the studio is still working on the API and there are issues with some of the data and some features of the app don't yet work
• Added properties profiles to allow sets of options to be saved and reloaded - different profiles can be created with different app configurations. These can be created and loaded on the Properties screen, and can also be loaded at app start time with a command line argument by specifying 'profile profile_file_name.json' in the shortcut (e.g. short-cut Target: "C:\Program Files (x86)\Britton IT Ltd\CrewChiefV4\CrewChiefV4.exe" profile some_profile.json)
• Allow some properties to be modified without needing to restart the app
• Fixed an issue with missing opponent gap data when the player is running 2nd
• Added option to enable blue-flag messages ("Enable blue flag messages", defaults to enabled)
• Added option to limit the games show in the Crew Chief 'Games' list - to use this add a comma separated list of the games you want to be show to property 'Limit available games'. Most common versions and abbreviations of the game names should work here (e.g. "R3E, pCars2, Assetto, ACC, RF2")
• Allow radio beeps when the Chief talks to be switched off ("Enable radio beeps" properrty, defaults to enabled)
• R3E: extended pit menu interactions - you can now ask for a specific tyre type in car classes that support it, for example "box, soft tyres" (see R3E Pit Menu Interactions)

Version 4.9.8.8

• Fix potential crash bug when assigning buttons or when testing button assignments / voice commands before the app receives any game data
• Removed some debug code that may have triggered in the previous release

Version 4.9.8.7

• Rewrote installer to use WIX rather than InstallShield - should help with the updating issues that some users encounter
• Added an optional delay before switching the spotter to be switched off on full course yellow (default is to silence spotter as soon as the full course yellow is shown - to use the new behaviour disable the 'Mute spotter immediately on full course yellow' property)
• RF2 - added latest Formula E mappings and rules; R3E - improved accuracy of pit box countdown

Version 4.9.8.6

• Assign buttons when the button is released, not pressed. Should fix issues where continuously pressed buttons prevent button assignment from working
• RF2 - added ignore-blue-flags warnings
• R3E - added 'box, next tyre compound' voice command to cycle through available tyre types in the pit menu (see R3E Pit Menu Interactions section)
• R3E - added TireLoad data to WebHud export and incremented version number

Version 4.9.8.5

• R3E - corrected opponent tyre mapping for F1 and GroupC cars
• R3E - make use of pit menu data to provide more control over pit menu - added voice commands like "box, change front tyres only", and "box, don't fix aero". See R3E Pit Menu Interactions section here and in Help, or detailed forum post for more information
• A few minor fixes

Version 4.9.8.3

• Prevent the app spamming the console window with errors when something fails on every tick (should prevent crashes when something goes wrong)
• In 'keep quiet' mode (e.g. after telling the app to "shut up") it really does keep quiet - even high priority messages are blocked - only the spotter messages continue to play (these can be blocked with the "don't spot" command). If you want the old behaviour back, where 'keep quiet' mode still allows high priority messages to play, enable the "Play important messages when silenced" option
• Added a UI to add voice messages to the list of available button actions so you can easily assign a button to what would have been a voice command - press the 'Add / remove actions' button on the main screen to access this
• Added some missing validation on the good / bad start messages

Version 4.9.8.2

• Fixed app hang when using Trigger Word speech recogntion with nAudio
• Allow nAudio speech recognition input device sample rate, bit depth and channel count to be set in Properties
• Added some additional checks to prevent gap messages being played immediately after an overtake
• AC: don't load opponents into the speech recogniser once a race has started (should reduce CPU spikes in online races)
• AC: fixed inaccurate laps-remaining data
• iRacing - fixed some missing messages
• Various bug fixes and some code tidying up

Version 4.9.8.0

• Start listening as soon as the radio channel button is pressed, instead of waiting for the beep to finish playing - should make the speech recognition a little easier to use
• iRacing - revised fuel calculations in races with driver swaps to use highest per-lap consumption - should fix refuelling being wildly inaccurate due to missing consumption data when your team mate is driving the car
• iRacing & R3E - extended the speech recogniser to include opponent car numbers - you can now ask for opponent data using car number, e.g. "what's car number 10's best lap time", or "where is car number ninety nine". To use this, enable the "Identify opponents by car number" property. Note that for iRacing car numbers may have leading zeros - in cases where a given number appears more than once in the session (with and without leading zeros), the speech recogniser will expect the leading zeros to be used in the command (i.e. car number 021 can be referred to as "zero twenty one", "oh twenty one", "zero two one" or "zero twenty one" in all cases, and "twenty one" or "two one" only if there's no other car in the session with number 21)
• iRacing - Allow car numbers with leading zeros to be read by the full course yellow / formation lap code (e.g. car 009 will now be read as "zero zero nine")
• Reduce the maximum frequency of opponent tyre change messages to prevent spamming when many cars pit for different tyres at the same time

Version 4.9.7.9

• Fix for some potential start up issues
• Fixed toggle_mute button function not working properly
• RF2 - new plugin version and some additional DRS messages

Version 4.9.7.8

• Hotfix for spotter being always set to 'ovals' mode on road courses (missing beeps, some other changes - sorry guys). Ovals mode will now only be enabled on ovals, as intended
• Fixed nAudio beeps not responding to volume changes
• Added new button binding for 'Toggle mute' - mutes all app sounds and unmutes when pressed again

Version 4.9.7.7

• Change spotter behaviour on ovals to prevent the spotter monopolising the radio channel (non-spotter messages aren't blocked all the time). This disables the radio beeps on ovals and starts spotting immediately on race start. Note this affects oval tracks only. You can revert to the old spotter behaviour by disabling the 'Enable enhanced spotter on ovals' property
• Fixed some button assignments not working until the app was restarted
• Fixed broken pit stall count down
• Fixed some broken validation that was preventing gap ahead and gap behind messages playing in some circumstances
• Fixed broken 'play corner names' command
• Allow voice commands that refer to opponent cars (e.g. "what's the car ahead's last lap time") to be assigned to buttons - you need to add opponentDataCommand: true to the buttonAssignment element in controllerConfigurationData.json in these cases

Version 4.9.7.6

• Prevent fuel estimates playing too close together
• fixed cases where the app switches to multi-class mode when it shouldn't - when there are too many unknown car classes in a session the app now reverts to single-class mode as intended
• AMS / RF1 - update race start positions shortly after the green light - should fix cases where the 'bad start' message was playing when it shouldn't

Version 4.9.7.5

• Hotfix for iRacing crash bug

Version 4.9.7.4

• Allow fuel consumption calculations to be based on the lap with the highest representative fuel usage - this should produce more accurate fuel calculations on ovals and in cases where there's just been a full-course-yellow / caution period or other event that can significantly reduce fuel consumption. By default the app will use max per-lap consumption on oval courses and a windowed average consumption on road courses. Enable 'Base fuel calculations on max fuel consumption' property to use max per-lap consumption on all tracks
• Don't play laptime or pace report for laps which are several seconds slower than your pace
• A few assorted fixes
• R3E - added support for WebHud so Crew Chief can send data to WebHud in place of dash.exe. This should also be slightly more efficient that the old dash.exe program. Enable this with the 'Enable WebHud integration (R3E only)' property
• iRacing - additional messages for formation laps and full course yellows
• iRacing - reworked session position logic to reduce inaccurate position calls

Version 4.9.7.3

• R3E - added support for new shared memory layout introduced in latest game update

Version 4.9.7.2

• RF2 - incorporated more stock car rules and added some additional car class mappings
• RF2 - fixed some issues introduced in last RF2 game update
• Some minor bug fixes

Version 4.9.7.1

• iRacing - map the 'pits are open' flag and added BMW M8 car data and a couple of Okayama layout corner mappings (still some missing recordings here)
• RF2 - various tweaks including lone practice support and stock car improvements
• R3E - mapped Sepang and Nordschleife corners (VLN and Nords layouts only) - might not be very accurate (it's a big track and the available maps aren't great)

Version 4.9.7.0

• Don't play lap time comparisons during full course yellow
• Fixed button assignments being ignored when Voice Recognition Mode is set to 'Press and release button'

Version 4.9.6.9

• Minor bug fixes
• AC: ensure tracks always have 2 or 3 sectors - this *definitely* fixes long-standing issues with some longer add-on tracks that report 4 or more sectors

Version 4.9.6.8

• Some stability fixes

Version 4.9.6.7

• Fixed nAudio speech recognition
• Some more minor improvements to the controllers code

Version 4.9.6.6

• Simplified macros file format (removed the per-game key mappings) and added a UI to allow macros to be created and edited from the app. Important: if you've created your own macros or have been helping us test our recent beta releases, please rename Documents/CrewChiefV4/saved_command_macros.json before starting the app. See Command Macros section of help.txt for more info
• Re-wrote controllers code to cope with badly behaved devices (device scans that take many minutes and devices that disconnect and reconnect during play). Controllers are no longer scanned at start-up (press Scan for Controllers to initiate a device scan)
• Moved saved button assignments to Documents/CrewChiefV4/controllerConfigurationData.json. This has been extended to allow any of the existing basic voice commands to be mapped to a button - see Button Mappings section in help.txt for more info
• Allow cut track warnings to be enabled / disabled with a voice command ("enable cut track warning" / "no cut track warnings") or a button binding ("Toggle cut track warnings on / off")
• Some simple camber and pressure responses using average inner-middle-outer tyre temps recorded during the previous lap (voice commands "how are my [front / rear] cambers" / "how's my [left front / right front / etc] camber", and "how are my tyre pressures" / "how are my [front / rear] tyre pressures"). You can also add "...right now" to this voice command to get the current inner-middle-out temps (not averaged). Note this isn't well tested, might give bad advice, and doesn't work with iRacing
• AC - another attempt to fix weird crash on tracks with > 3 sectors
• RF2 - updated plugin to include stock car rules logic and added more stock car (oval) specific messages
• RF2 - added more messages for various penalties and other conditions;

Version 4.9.6.4

• Automatically scan for controllers on app start
• Better handling of controllers
• Disable some irrelevant messages on in-laps
• RF2 - better (more detailed) penalty messages
• RF2 - updated plugin with more data and additional features not exposed via official rF2 Internals API. These are turned off by default - to enable them see 'rFactor2 Unofficial Features' section in README.txt

Version 4.9.6.3

• Tweaked manual rolling start logic for multiclass races, so each class has its own pole-sitter for determining when to start the race (can be disabled with the 'Manual formation lap separate classes' option)
• Significantly reduced the size of debug traces
• Reworked console logging output to fix some potential crash bugs
• iRacing - potential fix for incorrect race start position in multiclass races (this caused quite a few issues)

Version 4.9.6.2

• Hotfix for iRacing crash

Version 4.9.6.1

• Extended free-text macros a little (upper case characters and slash)
• prevent off-track messages expiring immediately in practice sessions
• speech recognition fixes when running with 'disable alternate voice commands' switched on
• automatically save console logs
• iRacing - fixed debug logging on ovals
• RF2 - some bug fixes

Version 4.9.6.0

• Corrected some car classes for AC and R3E
• RF2 - updated plugin
• RF2 - more accurate pit stall location detection
• Added Billy Strange spotter with latest sound pack update

Version 4.9.5.9

• Notify when given slowdown penalty
• AC - fix crash when restarting app
• a few minor fixes

Version 4.9.5.8

• Some fuel calculation tweaks - near the start of the race, use the max per-lap consumption when calculating required fuel
• Save pitstop benchmark times for each car / track / game combination so they persist between runs of the app (written to /Documents/CrewChiefV4/pit_benchmarks.json) - this is enabled by default but can be disabled with the 'Save pitstop benchmark times to disk' property
• RF2 - workaround for missing spotter calls after driver swaps (thanks to kcr55 for this one)
• RF2 - use tyre compound name rather than index when deriving tyre types - should fix issues where mods declare different available tyre compound sets
• pCars2 - make macro key presses a bit longer so they're less likely to be missed by the game (note this makes the refuelling macro execute quite slowly)

Version 4.9.5.7

• Fixed RF2 tyre type mapping and added Hyper-Soft tyre
• Use correct 'drizzling' sounds
• Added spotter 'Florian' (in latest sound pack update)

Version 4.9.5.6

• Don't allow some messages to be inserted into the space between spotter messages
• Some work to prevent stale messages being played (e.g. after a delay caused by the spotter)
• Don't play fuel warnings when on a low-fuel run in qualifying or practice
• Prevent some position messages being played twice
• Reduce repetition of some messages
• Ignore rear tyre and brake temperatures in FWD classes
• More internal threading fixes
• A few other tweaks and fixes

Version 4.9.5.5

• Macro overhaul - more flexible system which should be easier to work with. Includes example chat macros and an 'add fuel, XXX litres' macro (where XXX is 0 - 150) (R3E and pCars2 only). See the 'Advanced command macros' section of the help.txt file or http://thecrewchief.org/showthread.php?263-Command-key-press-macros&p=2378&viewfull=1#post2378 for more info
• Fixed some shutdown delays that can happen when closing the app without pressing 'stop' first
• Fixed radio channel sometimes being left open after a spotter call
• Fixed brake and suspension damage not being reset after repairs
• Added option to play pit box distance messages in feet ('Pit box distance countdown in feet')
• Added option to play a 5-4-3-2-1 style pit box count down ('Pit box time countdown' property, disabled by default). Reaches zero 30 metres from the pit stall by default (configurable with 'Pit box time countdown end point (metres)' property) - note that this may be inaccurate if the pit box is close to the start line due to the way lap distances work when in the pit lane, especially on tracks where the pitlane is significantly longer or shorter than the racing surface
• Make volume control sliders more fine grained to allow better control over volume
• RF1 / AMS: revised cut track logic - should reduce cut track warnings
• pCars2 - 'request pit' macro now checks the pit request state from the game and responds accordingly
• pCars2 - added "cancel pit request" macro
• Various bug fixes

Version 4.9.5.3

• Internal overhaul for better performance and stability. Fixes some threading / resource issues that could cause instability on shutdown, changes to how the internal event processing works to make it faster and less resource-hungry, removed 'disable immediate messages' option as this is no longer needed, reduced CPU overhead in lots of other places
• Fixed app crash when failing to initialise nAudio background sounds player
• pCars2 - added 'pCars 2 spotter car length' property, default 5 metres (app was using whatever had been set in the pCars1 version of this property)

Version 4.9.5.2

• Fix laps-to-go calculation - it's now based on the number of laps completed by the overall leader so should be correct when you've been lapped
• Allow for changing conditions when determining the player's pace and best lap time - comparisons are only made to laps completed in broadly similar conditions and best lap set in the current conditions is used when working out things like expected laps remaining and required fuel loads
• Fixed rounding errors in fuel calculations that could accumulate to substantial amounts
• Use overall fuel consumption when determining how much fuel to add, rather than recent fuel consumption (the app sometimes under-fuelled if the player was fuel saving in the laps before his pit stop)
• R3E - fixed some missing state transitions
• pCars2 - use updated RainDensity data for more fine-grained rain calls
• Some performance improvements

Version 4.9.5.1

• Added support for F1 2018 *spotter only*. This uses the UDP data stream sent by the game - the app listens on the default port 20777 (can be changed with the 'F1 2018 UDP Port' property). This is an early implementation so expect some bugs - please report them. Again, it's only the spotter - the app doesn't interpret any of the other game data so it won't give other calls or be able to answer any questions. I may add full support later, but as the crew chief built into the game is actually pretty good this isn't a high priority
• RF2 - updated plugin to latest version

Version 4.9.5.0

• Some fuel calculation fixes
• Added fuel-window messge in races which have no mandatory stop but will need a single fuel stop
• Some internal fixes
• Reduced likelihood of yellow flag warnings for cars that have already quit to pits
• iRacing - fixed issues with opening lap data

Version 4.9.4.9

• Added alarm clock function - say 'set alarm at twenty oh five', for example or preset it in properties "Alarm time(s). "Enable alarm clock voice commands" must be enabled before the alarm clock voice commands works
• Alternate sound pack internal rework
• Mark abandoned laps as invalid
• More ghost detection improvements
• R3E - removed 'confirm penalty' macro as this is no longer needed and can cause issues
• Reworked fuel-to-end reserve calculation - you can now specify a number of laps worth of additional fuel to add as a reserve when fuelling to the end of the race. The 'Additional fuel to add to finish the race (number of laps worth)' property can be a whole or fractional number of laps
• Various bug fixes

Version 4.9.4.6

• Enable some of the multiclass warnings in qualifying and practice sessions
• Allow the wait timeout for Trigger Word speech recognition mode to be set ('Trigger word wait timeout', default 5 seconds). The app will wait this many milliseconds for a command after hearing the trigger word before giving up
• Fixed some broken personalisations from the last update (a few of the personalised messages weren't loading)
• iRacing - better 'oval' detection (should prevent the app using oval spotter sounds on some road courses)
• iRacing - allow 'add fuel' voice commands without a unit (e.g. "pitstop add 12") - will use whatever fuel unit the app is configured to read fuel amounts in

Version 4.9.4.5

• Added 'Trigger word' voice recognition mode. With this enabled voice recognition works a bit like 'OK Google' or Alexa - the app listens for a special keyword or phrase (configurable in the 'Speech recogniser trigger word' property, default value 'Chief'). When it hears the keyword it starts listening for a regular voice command for a few seconds. This doesn't work with nAudio input
• Some corner name mapping fixes
• Changed default interrupting behaviour so only spotter messages interrupt the Chief
• Only consider rear wheels as locked if both are locked at the same time in common FWD cars like WTCC and WTCR (prevents the app warning about locking the unloaded inside rear on turn-in)
• When requesting fuel estimates for a given time or lap count, the app now reads back the time / lap count you requested along with the fuel estimate (e.g. "for 25 minutes, we estimate you'll need about 30 litres")
• R3E: reworked hotlap single practice mode detection - should prevent spotter playing in these game modes
• Various internal fixes

Version 4.9.4.3

• Fixed a few cases where messages play when they shouldn't
• Reduce repetition of blue flag messages
• RF2 - fix 1970s F1 class mappings
• iRacing - use average temp round track now this has been updated in the SDK to be dynamic

Version 4.9.4.2

• Prevent unimportant messages playing if the player is fighting with other cars in a race session or is on a flying lap in a qualifying session (disabled by default, enable this with the 'Advanced message prioritisation' option)
• Allow app update check to be skipped - adding the start argument SKIP_UPDATES to your shortcut will prevent the app checking for updates (but it'll still check for sound pack updates)
• Report yellow flag messages even if we're in a corner / braking zone
• Various bug fixes and tweaks

Version 4.9.4.0

• Fixed regression in non-English speech recognition config files - the 'defaultLocale' property name for speech recognition language had been changed to 'language', so the app was ignoring this value in existing configurations. The app will now use the 'defaultLocale' property value if it doesn't find a 'language' property

Version 4.9.3.9

• Allow spotter messages to play if they have interrupted another message, even if they would otherwise have expired
• iRacing - enable fuel tracking in lone practice sessions
• iRacing - Added option to re fuel to end of race in a race session when entering the pitlane, this will not trigger if you get a tow back to pits it only works for regular preformed pitstop!
• iRacing - some multiclass fixes
• pCars2 - performance improvements
• internal rework - consolidated lots of timings code to make behaviour more consistent across games
• Speech recognition engine initialisation improvements - better handling of language / country options, better management of installed components and error reporting
• Improvements to interrupting logic
• Various bug fixes

Version 4.9.3.7

• Added option to pause most messages in braking and cornering zones (sections of the track starting from heavy braking and ending with near-full throttle application) - this doesn't apply to spotter messages or other very high priority messages. It can be enabled and disabled with a button mapping ('Toggle delay messages on hard parts') or a voice command ('don't talk in the [corners/braking zones]' / 'no messages in the [corners/braking zones]', 'talk to me anywhere' / 'messages at any point'). This feature is switched off by default - the initial state is set with the 'Delay messages on hard parts' option. Note that you need to drive at least one valid lap before the app can work out which sections of the track it needs to keep quiet in. This feature is disabled for ovals and may produce odd results on very short tracks
• Added some basic message prioritisation - higher priority messages will be inserted into the queue in front of lower priority messages
• Replaced the 'Spotter and responses block other messages' property. The spotter (and some 'critical' messages) now interrupt and block regular messages (most things except voice command responses and some other important messages) by default. Enable the 'Command responses and important messages block other messages' to allow other types of important message (such as voice command responses and yellow flags) to also interrupt and block messages
• Prevent any further fragments of a message from playing if this message was interrupted
• Simplified pitstop benchmark process - you can now get a benchmark pitstop time without having to set a hot lap first (although you'll still need to set one after your stop to allow the app to work out the time loss)
• A few bug fixes

Version 4.9.3.6

• Reduce size of 'personalisations' update pack install this update before updating your personalisations
• Much more accurate tyre life prediction using a non-linear curve fit of tyre wear data recorded for the current tyre set (assumes a tyre is worn out when it has 5% life left)
• Added more info to the fuel status message - now includes fuel-to-end
• Allow spotter sounds to cancel other queued messages (disabled by default, enable with 'Spotter and responses block other messages' property - note this can sound strange when only the start or end sounds of a message play)
• A few minor tweaks
• iRacing - fix white-flag message spam

Version 4.9.3.5

• Fixed sound pack version check

Version 4.9.3.4

• Changed how sound pack downloads are handled - should significantly reduce the size of sound pack updates
• Added property categories to make finding stuff easier
• Added opponent pit exit prediction warning - if the app thinks an opponent car will probably come out of the pits close to you (and it can read his driver name), you'll be warned about him
• Further opponent pit exit estimation improvements
• some internal bug fixes

Version 4.9.3.3

• Fixed opponent time in pitlane when timing opponent stops for pit strategy calls
• Take mandatory pitstop status into account when deriving expected post-pit opponent positions (assume opponents who still haven't pitted will pit this lap if we're at the end of the pit window)
• Added and corrected a few car classes (pCars2, iRacing and R3E)
• iRacing - fixed some car class allocation issues

Version 4.9.3.2

• Improved pit stop exit prediction when opponents are in the pitlane
• Don't reset the fuel data when leaving the pits during a race, unless we've added fuel

Version 4.9.3.1

• Hotfix for pitstop prediction additions (see previous release notes). This fixes the wildly inaccurate pit stop time loss estimates reported by the pitstop benchmark process if you make the benchmark request too late in the lap (after you've entered the final sector)

Version 4.9.3.0

• First cut of pit exit prediction - obtain a benchmark pit time in practice by making the 'time this stop' / 'practice pitstop' / 'time this pitstop' / 'pitstop benchmark' command, or by pressing the "Pitstop prediction" button before make your practice stop. The pit exit prediction will play automatically some time after requsting a stop, or if you make the 'Where will be be after a stop?' / 'Estimate pit exit positions' / 'What will happen if I pit?' command, or by pressing the "Pitstop prediction" button during a race (see 'Pit exit position prediction' section in the readme.txt)
• Disable cold brakes warnings for some car classes
• R3E - detect if this and next laps are invalidated due to cut track in quali/practice
• R3E - disable pit stall position messages in post race
• R3E - improve cut track detection
• R3E - fix best lap time not announced during leaderboard challenge
• AC - fix crashes due to unexpected timings reported by the game
• Suppress crashes when using Naudio Input - (but please send us log file if you get exceptions in log)
• Fix issue where best lap time is lost if it is set after an invalid lap
• Fix incorrect gaps announced if vehicles aren't within the same lap
• Fix DRS messages announced incorrectly if opponent is pitting
• Make 'half fuel' call play at exactly half fuel (was playing a bit too early)
• App wide bug fixes

Version 4.9.2.9

• Allow pit countdown past session finish (for cooldown lap)
• Don't grumble about a stopped engine if the car is still moving
• Some additional checks to handle delayed opponent position data
• iRacing - improve live position tracking
• iRacing - improve retired vehicle detection
• iRacing - race finish position improvements
• iRacing - finishing position detection improvements
• iRacing - reliability fixes)
• rF2 - suppress pit messages while in garage/monitor
• AC - fixed crash bug on 2-sector tracks
• R3E & pCars2 - use game-provided time gaps to car in front / behind (more accurate than derived gaps)
• R3E - DRS message accuracy improvements
• R3E - removed auto-confirm pit macro and associated logic (no longer needed, and can cause some issues with pitstops)
• R3E - disable spotter in hotlap mode

Version 4.9.2.5

• Added commands to check self pace, you can ask "how's my self gap" / "how's my personal pace" / "how's my delta best" to see how you're doing relative to your own best lap
• iRacing - fixed pit stall countdown
• iRacing - fix finish position reporting
• iRacing - allow pit voice commands to be enabled or disabled ("Enable iRacing pit stop commands", default enabled). Disabling them removes them from the phrases the speech recognition engine listens for, potentially improving accuracy for other phrases as well as preventing false positives
• Added ability to specify if car class has speed limiter via "limiterAvailable" class field
• rF2 - enable pit stall countdown (doesn't work on some tracks, disabled on ovals)
• rF2 - Add option to force Rolling Start start type

Version 4.9.2.4

• Fixed incorrect car class data in R3E online practice and qualifying sessions
• Logging readability improvements
• Small AMS performance improvement

Version 4.9.2.3

• Hotfix for Assetto Corsa broken spotter

Version 4.9.2.2

• AMS off-track warning tweak - make 'kerb' a legal surface to drive on (should make the warnings much less common)
• A few other AMS fixes
• Half distance fuel calculation tweak to make it a little more conservative
• iRacing workarounds for missing opponent data when cars aren't rendered by the game
• A few other iRacing bug fixes
• Some UI tweaks to fix tab ordering and add shortcut keys (underlined on the UI)

Version 4.9.2.1

• Fixed missing fuel data in RF2
• Added option to specify how much 'reserve' to add when doing fuel calculations (enable the "Enable tight fuel calculations" property and set the reserve amount with the "Additional fuel to finish the race" property)
• Fixed iRacing SoF calculation
• Various minor tweaks

Version 4.9.2.0

• IMPORTANT FOR IRACING USERS: This release includes changes to address recent stability issues. Unfortunately we've not had enough feedback to be sure these have worked. By default the app will continue to use a component that had been causing crashes - we've modified this component to fix the crashes but it still needs more testing. If the app crashes (disappears with an error message popup, taking focus away from the game) then please tell us. If you experience crashes go to the Properties screen and disable the 'iRacing faster parser' property
• New RF2 shared memory plugin with better performance
• Reinstated an iRacing crash fix that got lost in a previous update

Version 4.9.1.7

• Added tyre temperature thresholds for some missing tyre types (including wets) - should fix incorrect temperature warnings on wets and some other tyres
• Mapped player tyre type in pCars 2 (note this doesn't support mixed tyre types)
• Fixed an issue with iRacing driver swaps that caused log-spam and performance issues

Version 4.9.1.6

• iRacing hotfix for crash in mapper

Version 4.9.1.5

• More detailed error messages
• pCars and pCars2 performance improvements
• iRacing performance improvements
• AC fixes for shorter tracks (2 sectors)
• Fixed inaccurate race position messages in iRacing 'checkered flag' phase
• Some iRacing stability improvements
• Use relative lap time difference when working out when to give multi-class warnings. This uses 2 new Properties - 'Multi-class slower car warning time' and 'Multi-class faster car warning time' - this is the approximate average amount of notice you want the app to give you when approaching a different class car
• Added iRacing voice commands to get out of car ('get out') and get the average SoF ('what's the sof' / 'what is the strength of field')
• For Assetto Corsa, only allow multi-class races if the number of unknown car models does not exceed property 'Max unknown car models in ACS multi-class races' (default 0) - this is necessary because Assetto doesn't expose proper class data. This prevents the app dividing participants into different classes unless the app recognises all the car models in the session

Version 4.9.1.4

• Workaround for iRacing opponent pitting message spam

Version 4.9.1.3

• Minor multi-class tweaks
• Assume single class if most car classes in a race are unknown to the app (AC, rF2 and rF1 only)
• Added button to save console output to a file (in Documents/ CrewChiefV4/debug/)
• Some AC internal fixes for inaccurate lap count data
• Don't give damage and tyre wear responses in iRacing
• Added Lee spotter and updated Geoffrey spotter to add missing oval sounds (in latest sound pack update)

Version 4.9.1.1

• Major internal overhaul to fully support multiclass races - opponents and positions are now tracked correctly for the player's car class, the app doesn't make calls about opponent laptimes, pitting, and other stuff if they're not in the same class as the player
• Added multi-class specific messages for when you're lapping or being lapped by other classes
• Added multi-class specific voice commands "is the car ahead in my class", "is the car behind my class", "what class is the car ahead", "what class is the car behind" and variations
• More performance improvements
• Speculative fixes for driver swaps in iRacing
• Fixed 'enable driver names' flag being ignored for some messages
• Added optional pit box countdown (R3E and iRacing only, disabled by default - enable with property "pit_box_position_countdown")
• rF2 improvements: improved rolling start detection and distance to safety car detection, in SCR mode Crew Chief now respects DoubleFileType value and will announce last FCY lap Frozen Order instructions correctly
• Added option to change left/right side tyres(iRacing only)
• Modified R3E pit macros to take advantage of modify pit menu behaviour (should make the pit macros, particularly the auto-confirm pit actions, more reliable)
• Retrieve gap ahead / gap behind as late as possible when playing gap messages to improve accuracy
• Made auto-refuel ("fuel to the end" macro in R3E and "pitstop fuel to the end" command in iRacing) a bit more conservative - more so at longer tracks

Version 4.9.0.7

• Added messages for oil and fuel pressure warnings (iRacing only)
• Added messages for stalling the engine
• Added messages when you crash very heavily - the app will ask if you're OK and, if you're using voice commands, wait for you to respond (these can be disabled with the "Enable crash messages" option in Properties)
• Only use start-line track temperature in pCARS to prevent the app calling local track temp variations
• Allow multi-class support to be disabled ("Force single class" property) - useful if you're playing with 3rd party content that has incorrect car class IDs
• More performance improvements
• Prevent the app's windows being resized such that controls are no longer visible (this behaviour can be disabled by unchecking the "Force minimum window size" property)

Version 4.9.0.6

• Don't play 'good pass' message in pCARS 2 if we've just collided with someone (might still need some tuning)
• Some minor performance improvements
• Fixed issues with historical weather data being lost
• pCARS 2 pit window fixes (again...)
• Fixed missing DQ / DNF session end messages
• Fixed mid-point fuel report saying "fuel looks good" when it clearly isn't good

Version 4.9.0.5

• Fixed 'box this lap' messages playing in pCARS2 even though the player had completed his mandatory stop
• Some pCARS2 off track warning tweaks
• Reworked R3E opponent lap invalidation code - should prevent the app incorrectly invalidating opponent laps
• Speculative fix for session end being 1 lap too late for iRacing fixed number of lap races

Version 4.9.0.4

• Added voice command to get and estimate of how much fuel is needed to finish the race - "how much fuel to the end" / "how much fuel do we need"
• Added voice command to get an estimate of how long the tyres will last (in minutes for timed sessions, laps for fixed lap number sessions) - "how long will the tires last" / "how long on these tires" / "how long will these tires last"
• Added check to prevent a stopped car triggering incident warnings repeatedly
• Added ability to set pit fuel amount in iRacing - "pitstop fuel to the end" / "pitstop fuel to the end of the race" - and via a macro in R3E and pCARS2 - "fuel to the end" / "fuel to the end of the race". See the 'Advanced command macros' section of the help.txt file or this detailed forum post for more info (please read the documentation before using this in R3E or pCARS2 as it requires the default in-game pit strategy to be configured in a particular way, and is quite fragile - use at your own risk).
• Immediately close the pit menu in R3E after running a macro if we're close to the pit entry (if the menu is left open when you cross the limiter line, the auto-confirm macro will fail)
• If sound pack downloads fail, retry with the other server - should fix issue that prevented some users downloading sound updates

Version 4.9.0.3

• Don't make Assetto Corsa spotter calls when viewing replays
• Derive opponent laptimes and sector 3 times in Raceroom instead of using data provided by the game as the data provided by the game are always 1 lap out of date
• Reworked some of the sector gap logic
• Reduce frequency of repeated "the next car is..." messages

Version 4.9.0.2

• Fixed some issues in pCARS 2 session end detection and pre-start message triggering
• Disable pcars2 spotter in pits
• Some minor performance improvements

Version 4.9.0.1

• Hotfix to prevent some stock car rules messages triggering when they shouldn't
• Don't read lap times or gaps if we're under full course yellow
• Added possible track cut warning for pCars2

Version 4.9.0.0

• Added support for rF2 StockCarRules plugin, CC will now announce Lucky Dog, Wave Around, EOLL messages. To enable make sure you enable the "Use American terms" option, disable StockCarRules plugin in rF2, and set "EnableStockCarRulesPlugin":1 for "rFactor2SharedMemoryMapPlugin64.dll" - see this detailed forum post for more information
• Add option to disable pit state announcement during FCY in rF2 and rF1/AMS
• Disable brake temp messages on ovals
• Fixed pit macros not working for some R3E players
• Prevent some messages playing when they're not appropriate or no longer relevant
• Some internal fixes

Version 4.8.3.2

• Fixed AC plugin after game update - the app should ask if you want to update the plugin when you first launch it in AC mode
• More fixes to the manual rolling start logic
• iRacing session transition crash fix
• Some car class tweaks
• Added nAudio speech recognition code to allow voice recognition input device selection (enable with property "Use nAudio for speech recognition" - thanks to Daniel Nowak for this one)
• Disable sector delta messages on ovals and use more generous spotter parameters

Version 4.8.3.1

• Corrected some pCARS 2 track names that got changed in the last pCARS 2 patch
• Disable some irrelvant sounds when racing on ovals
• Work around for some missing spotter sounds
• A few internal fixes

Version 4.8.3.0

• Changed personalisations download process to reduce bandwidth use

Version 4.8.2.9

• Fixed a serious regression in multi-class race position tracking (sorry for the double release guys...)

Version 4.8.2.8

• Added more variety to race finish messages
• Make default R3E pit macro pause a while before closing menu
• Warn when an opponent car is exiting the pits
• A few other minor bits and bobs

Version 4.8.2.7

• Experimental support for double-file manual rolling starts (R3E, pCARS2 & AC only - enable with "Manual formation lap double-file start" property)
• Fixed arrow keys and some other keys not being released when used in command macros
• iRacing rally cross fixes
• More Formula E battery tracking logic and messages
• Split some longer voice command responses so if you want to hear more, you have to ask ("more information" / "more info" / "clarify") - currently only implemented for Formula E battery messages, but will be extended. If you want all the information in a single long response without having to ask for clarification, enable "Verbose messages" property
• Added missing RF1 / AMS blue flag override ("Enable AMS / rF1 blue on slower" property
• Some internal fixes

Version 4.8.2.6

• Fixed some nAudio bugs that meant the radio beeps were being sent to the wrong audio device
• Added Hong Kong track mappings (RF2 Formula E pack)
• Added voice command to get player incident count ("how many incidents do I have" / "what's my incident count") and session incident limit ("what's the incident limit") - iRacing only
• Added voice command to get player licence ("what's my licence class") and iRating ("whats my iRating") - iRacing only
• Added voice command to get opponent licence ("what's [the guy in front's / the leader's / p10's / Bob's] licence class") and iRating ("what's [the guy in front's / the leader's / p10's / Bob's] iRating") - iRacing only
• Fixed tyre temperature thresholds on some R3E car classes
• Battery monitoring bug fixes

Version 4.8.2.5

• Reworked battery status message (response to voice command/button command), added battery use increase/decrease detection
• Added pit stop related messages for pCARS2
• Some internal bug fixing
• Allow spotter sounds ("car left" etc) to have their volume scaled relative to the other voice messages (property "spotter_volume_boost")

Version 4.8.2.4

• Added battery related logic for electric cars (RF2 Formula E)

Version 4.8.2.3

• Fixed some performance issues when using nAudio playback
• Some internal sound player rework and bug fixing
• Added "TTS volume boost" - by default the TTS sounds are now played at 2x volume, which balances them better with the the other sounds
• Added TTS trim start and trim end properties to remove silence from TTS sounds
• Added "Only use TTS when there is no alternative" option. When set to 'true' (the default) the app will drop messages or use generic terms to refer to opponents when it doesn't have a driver name recording. It will use TTS for driver names only if the message is considered essential (when e.g. responding to "who's in front?" voice command). The recommended TTS configuration is now to enable TTS, set "Only use TTS when there is no alternative" to true, set "TTS volume boost" to 2, "Trim end of TTS sounds" to 600 and "Trim start of TTS sounds" to 100 - see 'Help and getting started' for more information
• Allow iracing tyre pressure adjustment voice commands to be made in PSI (when property "iRacing tyre pressure adjustments in PSI" is true the app assumes you mean PSI)
• Fixed broken voice recognition for "who's ahead", "who's behind" and "who's leading" commands
• Added Ross spotter to latest sound pack
• Allow iRacing fuel to be added in gallons

Version 4.8.2.1

• Work-around for R3E missing sector number updates when cars exit to pits (should fix a lot of inaccurate calls in practice and qualifying)
• Fixed mute not working properly in nAudio mode
• Simplified track landmark generation (see Help)
• Some internal bugfixes

Version 4.8.1.9

• Improvements to speech recogntion accuracy
• Integrated nAudio library for sound playback which allows you to choose play back devices for messages and background sounds (disabled by default - enable this with the "Use nAudio for playback" option) - this also allows the app to play back at higher volumes
• Added lots of iRacing pit commands (see the voice commands section in Help)
• Lots of iRacing bug fixes
• Added a new spotter (Micha - in the latest sound pack)

Version 4.8.1.7

• Opponent to player delta bug fixes (all games)
• Added macros for some iRacing black-box interactions
• Added new Pace Notes feature for recording and playing back user-created pace notes (see Help)
• Fixed arrow keys not working for macros
• Fixed a few minor lap time reporting issues
• Lots of iRacing fixes

Version 4.8.1.5

• Better UI handling of sound pack downloads (app should no longer appear to hang while unpacking sounds)
• Announce retired and DQ'ed drivers in RF2
• Fixed stale driverID in iRacing
• Minor bug fixes - Mark out laps as invalid in R3E (should prevent stale lap time calls at the end of an out lap), RF2 pre-lights and overtake messages and track landmark mapping getting lost on session restart, pCARS 2 pit exit messages

Version 4.8.1.4

• Better pruning of pCARS2 stale and duplicated opponent data in online sessions (hacks adapted from pCARS1 to work around bugs inherited from pCARS1)
• Added opponent retired and opponent disqualified messages (pCARS2 / R3E) - will be enabled with next sound pack update
• R3E and pCARS2 car and track mapping fixes

Version 4.8.1.3

• Fixed an issue in the speech recogniser where grammars were initialised multiple times, reducing recognition accuracy - this should make the recogniser work more reliably
• Fixed an issue in R3E and AC where a invalidated in sector 3 could cause stale best-lap data to be announced
• Remove opponents who are reported as DNF / DQ / DNS in R3E
• Added experimental option 'Disable alternative voice commands' (disabled by default). Enabling this will force the speech recogniser to only load the first command from each row in speech_recognition_config.txt. Instead of recognising any of "who's leading", "who's in the lead", "who is leading", "who is in the lead", or "who's the leader" the app will only recognise the first in the list - "who's leading". This will limit the number of phrases the recogniser understands and *may* improve recognition accuracy

Version 4.8.1.2

• More iRacing bug fixes, mostly around session state tracking
• Improved default pCARS2 command macros (massive thanks to Belaki on the pCARS forums)
• Fixed pCARS2 pit window end message playing when it shouldn't
• RF2 bug fixes
• Added overall damage report - triggered by voice command ("damage report / how's my car / is my car ok") or button assignment
• Added session status report (race time remaining, pit status, gaps etc) - triggered by voice command ("session status / race status") or button assignment
• Added car status report (damage, fuel, tyres etc) - triggered by voice command ("car status") or button assignment
• Added combined status status report (session status + car status report) - triggered by voice command ("full update / full status / update me") or button assignment
• Added a few more messages

Version 4.8.1.1

• Corrected and added some corner mappings
• Added function to read corner mappings for the current lap (activated with a button assignment or voice command "read corner names" / "corner names" / "tell me the corner names")
• More iRacing beta updates
• Tweaked overtake message probability

Version 4.8.1.0

• iRacing beta
• pCARS2 beta (shared memory only - UDP isn't ready)
• Pit command macros beta (example implementations for R3E and pCARS2 included - see the "Command macros" section at the end of the Help file, and saved_command_macros.json in the app's installation folder)
• Fixed lap time issues in AC (caused by the laptime not being sent to the app at the same time as the new-lap notification)
• Extended support for RF2 StockCar rules plugin
• More car class and track mapping data
• RF2 opponent pit detection and additional pit messages
• Mute the background sound when you talk to the chief
• Block all messages when you're talking to the chief (optional - use property "Block messages when talking to the Chief")
• Small improvements and bugfixes for RF2, PCars, AC and R3E
• Attempt to predict when it might rain for pCARS and pCARS2 (shared memory only, enabled by default - use property "Enable PCars rain prediction using CloudBrightness" to disable). Note this uses changes in reported CloudBrightness value and is quite inaccurate

Version 4.8.0.7

• RF2 fixes - fixed low fuel message playing when it shouldn't, fixed European versions of full course yellow messages not playing on new installs

Version 4.8.0.6

• RF2 DRS support
• RF1 / AMS and RF2 cut track warnings
• RF2 full-course-yellow, standing start and rolling start order messages (pace line, grid box, left / right column)
• R3E opponent laptime validation fix - should prevent the app playing some incorrect opponent laptimes
• Don't play aero damage if the rest of the car is knackered
• Fixed first lap out of pits massively skewing fuel consumption estimate
• Some other random fixes

Version 4.8.0.2

• Fixed broken PCars2 oval track mapping - should now correctly call 'car low' / 'car high' on ovals for all spotters except Geoffrey

Version 4.8.0.1

• Added some Project Cars 2 stuff - game type, launch options, and a couple of initial track mappings
• Fixed some incorrect tyre temperature warnings

Version 4.8.0.0

• Updated Assetto Corsa plugin to be compatible with latest AC update
• Added "Block messages when talking to the chief" option - this prevents any messages being played while you're making a voice command
• Some fuel consumption calculation fixes

Version 4.7.9.9

• R3E 64Bit support
• Added voice command to tell you (once the data is availalbe) what the relative performance difference is between different tyre types based on the best lap in the session for tyre type - e.g. "Softs are about 0.4 seconds faster than Mediums, Mediums are about 1.2 seconds faster than Hards". The voice command is "Give me tyre pace differences", "What are the tire speeds?" / "Whats the difference between tires?" / "Compare tire compounds" (R3E and RF2 only)
• Added opponent tyre type info when they leave the pits after changing tyre type (R3E and RF2 only)

Version 4.7.9.7

• More RF2 race end detection fixes
• Added Imola corner mappings for R3E
• fixed race start message being repeated on manual rolling starts
• Some additional checks to prevent mandatory pitstop messages playing during or after you've completed your stop

Version 4.7.9.5

• Compatibility fixes for new Raceroom shared memory layout
• Map to new Raceroom tyre types - you can ask "what tyres is [opponent name] on?", or "what tyres am I on?"

Version 4.7.9.4

• Better sound pack update mechanism - wastes less bandwidth
• Added "minimise to tray" and "start minimised" options. Minimise to tray places a Crew Chief icon in the system-tray when you minimise the app, with a right-click menu contain commonly used functions. The app can be started minimised if desired
• Added a new fuel calculation command ("calculate fuel for [x] [laps / minutes / hours]" / "how much fuel do i need for [x] [laps / minutes / hours]" / "how much fuel for [x] [laps / minutes / hours]") - for example, "how much fuel do I need for twenty minutes?". Assuming the app's had the chance to record your fuel usage over at least one lap (the more the better), it'll estimate how much fuel you'll need for the requested number of laps / time based on your average consumption. IMPORTANT: if you use this to set your fuel load in a timed race you MUST add extra fuel to account for the lap you need to finish after the race timer reaches zero. The app WILL NOT DO THIS FOR YOU - if you put in exactly 20 minutes worth of fuel for a 20 minute race you'll run out on the last lap
• Only allow manual formation lap mode to supress messages in race sessions (fixes missing messages in practice and qual with manual formation lap mode enabled)
• Fixed session end detection in RF2 / AMS / RF1 - the app should also detect when you click 'next session' without clicking 'end session' first
• Fixed some issues in the fuel use tracking logic

Version 4.7.9.0

• Fixed initialisation errors in TTS engine which prevented the app from starting when "Use TTS for missing names" was enabled
• added option to select where the race starts on a manual formation lap - "Manual formation 'go' when leader crosses line". If this is true (the default) the app assumes that the race starts and cars are allowed to overtake as soon as the leader crosses the start line. If it's false, the app assumes that no one is allowed to overtake until they cross the start line
• Added some RF1 session identifier fixes - should correct a few issues caused by the app thinking the race was actually qualifying.

Version 4.7.8.9

• Fix for some settings getting corrupted on system which use a comma as a decimal separator - this causes some spotter and voice recognition issues. If you have already encountered this, please reload the app's default settings
• Added manual formation lap support. This supresses most messages on lap 1 and plays an alternate sequence of start messages - it assumes you're not allow to pass until you cross the start line. This mode can be activated and deactivated with a button press ("Toggle manual formation lap mode") or a voice command (enable with "this is the formation lap" / "formation lap" / "rolling start", disable with "standing start" / "no formation lap").
• Some fuel use calculation fixes
• Spotter fixes

Version 4.7.8.6

• Added optional radio beeps for when the spotter or the Chief interrupt each other. "Insert beep-out between Spotter and Chief" plays the close-channel beep after the chief / spotter has finished, and "Insert beep-in between Spotter and Chief" (the default) plays the open-channel beep before the chief / spotter interrupts. The spotter and chief use different beep sounds here, and these options can be combined if you want 2 beeps (close then open) when interrupting
• Attempt to delete corrupted settings and force the app to restart if they can't be processed
• Don't play fuel consumption estimate if it's 0 litres per lap

Version 4.7.8.1

• RF2 plugin fixes for car damage issues in online races

Version 4.7.8.0

• Fixed spotter logic where it would consider 2 cars along side to be "3 side", even if those cars were one behind the other
• Use oval spotter messages (inside / outside) when on known oval tracks, if the selected spotter has these sounds
• Tweaked spotter enable / disable sound to be a bit more appropriate for non-default spotter voice packs
• Fixed broken sector 3 time deltas in Project Cars

Version 4.7.7.9

• Fixed Assetto Corsa pit window open calculation for sessions with a fixed number of laps
• Fixed a crash bug when starting the app with no sound pack

Version 4.7.7.8

• Added dropdown to main screen to allow a different spotter voice to be selected
• Added Geoffrey Lessel's awesome spotter sounds - these are in the latest sound pack. Select "Geoffrey" from the new 'Spotter voice pack' menu
• Fixed a couple more spotter bugs
• Added button binding to get fuel status (consumption and fuel remaining). The "how's my fuel?" voice command now reports the consumption as well as the remaining fuel

Version 4.7.7.5

• More Scoops-Brand RF2 corner mappings
• Fixed some spotter bugs
• Added searching to Properties screen to make it a little less user-hostile
• Replaced the nasty underscore_property_names with proper names on the Properties screen

Version 4.7.7.4

• Substantial RF2 plugin rewrite
• Attempt to map game data if we detect the PCars2 exe - this does (apparently) work but expect some bugs and issues
• Ported some fixes from the PCars Android app - some free practice session improvements, more aggressive pruning of broken driver data, better (hopefully...) method of identifying player's data so monitoring other drivers shouldn't confuse the app

Version 4.6.7.2

• Overhauled internal sound handling to make the app behave better
• Use game-provided mandatory pitstop data where available (should fix app thinking you've completed your mandatory pitstop when the game thinks otherwise)
• Some more car and track mappings from Scoops
• Added 'three wide you're on the left' and 'three wide you're on the right' to the spotter - optional, disabled by default (spotter_enable_three_wide_left_and_right in the Properties screen)
• Added voice command to get info about the car in front / behind is slower / faster than you - "where should I attack" / "where am I faster" / "where can I attack" or "where should I defend" / "where am I slower" / "where is he faster" / "where will he attack"
• Mapped Watkins Glen for PCars
• A few bug fixes
• Added fuel use per lap response - "what's my fuel usage" / "what's my fuel consumption" / "what's my fuel use"

Version 4.6.6.4

• Faster start up times
• Better CPU usage
• Some internal fixes
• more of Scoop's corner mappings (recordings still to be done)

Version 4.6.6.2

• Fixed some RFactor and RFactor2 issues
• Added a few more track location mappings (thanks again Scoops)
• Disabled 'incident ahead' in R3E while I resolve the false-positives

Version 4.6.6.1

• Added a big set of corner name and location data thanks to Scoops' hard work
• Overhauled yellow flag logic for sector yellows and local yellows
• Read times accurate to hundredths of a second in some circumstances
• Added oval-specific behaviours (enabled per-track with a flag in trackLandmarks.json) - ignores brake and left side tyre temps, estimates tyre wear from right side tyres only
• Added an experimental 'realistic mode' option - enabling this supresses some messages based on car class and track (e.g. spotter is off at start of session when not on ovals, older car classes have less telemetry based info like tyre temps) - this is very much 'work in progress'; added per-car class behaviours for yellow flag phrasing (e.g. pace car vs safety car) and last lap message (e.g. "white flag" for last lap only applies to Indy and NASCAR cars)
• Added 'force update check' button

Version 4.6.5.2

• Fixed AC plugin after 1.14 update

Version 4.6.5.1

• Fixed a silly bug in the legacy R3E blue flag detection (used when flag rules are disabled)

Version 4.6.5.0

• Automatically switch between yellow and blue flag implementations in R3E depending on whether flag rules are enabled in-game
• Added some more incident calling and yellow flag options
• Added button mapping and voice command to suspend and enable yellow flag messages - enable with "give me yellows", "tell me yellows", "give me incident updates" or "give me yellow flag updates". Disable with "no more yellows", "stop incident updates", "don't give me yellows" or "don't tell me yellows"
• Fixed the "where is Bob?" voice message response in qual and practice sessions

Version 4.6.4.9

• Added R3E Mantorp Park (long), Norisring and Sachsenring corner data
• A bit more R3E flag tweaking

Version 4.6.4.8

• Skip 'dead' opponent data copies coming from PCars (should fix a few issues with inaccurate opponent data)

• Made opponent incident detection less sensitive and added an option to disable it (enable_simple_incident_detection)
• Reworked opponent lap and sector handling to fix incorrect sector time and pace reports (all games)
• Tweaked R3E yellow flag reporting to allow status changes to settle before reporting

Version 4.6.4.7

• A few minor bug fixes

Version 4.6.4.6

• Some more Raceroom flag calling tweaks - should be less noisy but may miss rapidly changing flag situations
• Added RF2 'stock car' mode (sound recordings to follow)
• Added R3E Nurburgring GP corner data

Version 4.6.4.5

• Some Raceroom flag calling tweaks

Version 4.6.4.4

• Initial support for Raceroom yellow flag implementation and revised shared memory layout

Version 4.6.4.1

• Fix crash bug in PCars with UDP data

Version 4.6.4.0

• Added installer for game specific plugins (AC, AMS / RF1 and RF2) - the app now offers to copy the required plugin files to the games' install directory if they're missing or out of date

• added more corner names
• opponent tracking fixes for PCars
• loads and loads of bugfixes and improvements

Version 4.6.3.2

• Temporary hack to reduce wheel locking sensitivity - hopefully will prevent false-positives while I work out a better algorithm

Version 4.6.3.1

• Temporary hack to reduce wheel spin sensitivity - hopefully will prevent false-positives while I work out a better algorithm
• fixed Assetto Corsa pit window calls being 1 lap out

Version 4.6.3.0

• New Python module for Assetto Corsa - please replace your existing ...\Steam\steamapps\common\assettocorsa\apps\python\CrewChiefEx\ folder with the new one in the app's install folder
• New plugin for RF2 - please replace your existing ...\Steam\steamapps\common\rFactor2\Bin64\Plugins\rFactor2SharedMemoryMapPlugin64.dll with the new one in the app's install folder
• Added corner names to some calls on several tracks (this is will a work-in-progress)
• Revised RF2 and AMS opponent data handling to fix missing gap messages
• More work on AMS session end bugs
• Added better reporting of yellow flags for AMS and RF2 - the app will sometimes tell you who's involved in the incident and what corner the incident is in
• Added simple incident reporting for known corners in R3E, AC and PCars
• Added attack / defend calls for known corners (note these messages don't play often - this is intentional)
• Added brake locking and wheel spin reporting for known corners

• Added Assetto Corsa damage reporting
• Lots of minor bugfixes and improvements

Version 4.6.1.5

• Fixed AMS multi-class support and added some AMS car classes

• Sort the game list alphabetically for the hard-of-thinking

Version 4.6.1.4

• Fixed pcars timed sessions

Version 4.6.1.3

• Fixed broken personalisations (oops)

Version 4.6.1.2

• Fixed broken settings preventing changes to any setting from being saved

Version 4.6.1.1

• Integrated personalisations - the app will ask you to download a new "Personalisations" sound pack. When this is complete the "My name" drop down box (top right) has a long list of names the app can use when addressing you. This replaces the old method of manually unpacking a prefixes_and_suffixes folder to the app's sounds
• Work-around for Assetto Corsa sometimes giving out of date position information
• Disable multi-class code for RF1 based games because the vehicle type data from Automobilista is too vague (things like "Ford" and "Peugeot")
• Ported RF2 full course yellow and sector-specific yellow flag announcements to Automobilista
• Removed irrelvant pit window messages from RF1 based sims - in offline sessions, if a pit schedule is defined the app will call "box now" in accordance with this schedule (assuming equal stint lengths) - this can be disabled with enable_ams_pit_schedule_messages property
• Fixed cut track warnings playing on out laps in Automobilista

Version 4.6.0.5

• Major overhaul of time reading (English sound pack - users of the Italian sound pack are unaffected)
• Added RF2 caution period and yellow flag events
• Scan for controllers only on request (press the "Scan for controllers" button to update the app's list of controllers) - this also improves the app's startup time
• Fixed Assetto Corsa missing race start after 1.12 patch
• Added chequered flag message for timed sessions (still some issues here with PCars)
• Reworked PCars session end detection; added controller bindings for message volume up / down

• Externalised car class definitions (first version - lots more work to do here)
• Lots of bug fixes

Version 4.5.0.0

• First cut of RF2 support, thanks to The Iron Wolf. This needs an additional .dll plugin for RF2 - see https://forum.studio-397.com/index.php?threads/crew-chief-v4-5-with-rfactor-2-support.54421/

Version 4.4.2.1

• Fixed some issues with pre-lights messages

Version 4.4.2.0

• Reworked pre-lights message logic (optional) - app will play race session messages while you're on the grid until the throttle / brake / clutch is pressed, then it'll play the 'get ready' message. This can be enabled by selecting 'play_pre_lights_messages_until_cancelled' option on the Properties screen
• Some driver name mapping fixes

Version 4.4.1.3

• Added more tyres for Assetto Corsa
• Fixed missing 'standby' response delay
• Reduced pre-lights message queue length

Version 4.4.0.2

• More Assetto Corsa additions and fixes including some performance improvements. IMPORTANT FOR ASSETTO CORSA USERS: remember to update the CrewChiefEx Python app from this new release (copy the CrewChiefEx folder from the app's install location to .../Steam/steamapps/common/assettocorsa/apps/python/). Note that sector times in multi-player are not yet accurate, and that player needs to drive 1 lap in single-player before sector gaps have been recorded.

Version 4.4.0.1

• Added missing Python plugin for Assetto Corsa. Copy the CrewChiefEx folder from Crew Chief's installation location to /Steam/steamapps/common/assettocorsa/apps/python and activate the plugin in-game.

Version 4.4.0.0

• First cut of Assetto Corsa support courtesy of Sparten - this is a work-in-progress
• Added blue flag max trigger distance (increase this to make the blue flag warnings play when the lapping car is further away)

Version 4.2.1.8

• Include more laps in the opponent vs player laptime comparisons during race sessions

Version 4.2.1.7

• Use lastSectorTime and lapInvalidated data for opponent cars when in PCars UDP (network data) mode. This makes the opponent lap time reports accurate as the app doesn't have to time them itself (this data isn't available in PCars shared memory data). I recommend using UDP mode for PCars on PC, rather than shared memory

Version 4.2.1.6

• Fixed PCars practice and qual session data being cleared when pitting (should fix a lot of the inaccuracies in these sessions)
• Pause messages after a "stand by" response

Version 4.2.1.5

• Don't play 'no tyre wear' after changing tyres

Version 4.2.1.1

• Fixed a bug in the gap-ahead logic that was triggering 'keep him under pressure' messages too often

Version 4.2.1.0

• Added support for secondary driver names mappings file 'additional_names.txt' so the auto-updater doesn't overwrite user-made changes to names.txt
• Additional validation on R3E sector reports
• Added "what's the fastest lap" and "what time is it" voice commands (reports session best lap for player class, and current [real world] time of day)
• A few bug fixes and minor improvements
• Reworked R3E tyre temperature checking to make better use of the core temps provided by the game (for new physics model cars)

Version 4.2.0.1

• Added ADAC 2015 and F4 RaceRoom classes
• PCars suspension damage threshold tweak
• Damage reporting rework
• Various bug fixes and minor improvements
• Don't play fuel messages while being refuelled
• Don't play wheel spin / locking when in the pits or when we have a puncture or missing wheel
• Fixed best lap and brake damage voice commands
• More frequent opponent gap reports on longer tracks
• Added brake and tyre temp warning on pit exit (when temps aren't optimal) - these are optional (brake temp warning is on by default, tyre temp warning is off)
• Some voice commands now trigger a "stand by" response, then a few seconds later the actual response (optional, enabled by default - uses "enable_delayed_responses" property)

Version 4.1.6.3

• Added Raceroom Formula Junior class
• Tweaked Raceroom engine damage thresholds

Version 4.1.6.2

• Some TTS revisions
• Updated RaceRoom car classes to match new patch

Version 4.1.6.1

• Fixed DTM 2014 tyre compound error in the 'box now' message
• Validate overtake messages to ensure they're not out of date by the time they're played

Version 4.0.3.5
