Group 5 is being worked on
Pagani Zonda (soon to be single make cup) was started on, but put on hold waiting for data.
Audi TT RS VLN is in the hands of Jürgen Wohlfarth for feedback on the handling, waiting for news from him.
GTR2 / GTR1 : dropped an idea somewhere on the forum about merging them and bringing in there the remains of the GTRX class, there's a pro and a con to that. Still think it would be good to have them all in a class with GTE specs.
Group A: Probably the next after Gr 5.

What’s New (Summary)
Massive physics overhaul for GT3-Specs classes, Prototype classes, GTO class. (Please note that the leaderboards of these classes have been wiped due to the overhaul)
 
Compact HUD to replace the mini hud.
 
FFB additions. Minimum force, slip effect, ffb meter, ffb multiplier per car.
 
Load/Save Car setups. Players can now save and load their car setups.
 
Bigger Grids. Maximum opponents on certain tracks can now go up to 100.
 
Fuel management in car setup
 
Oh, and new content too.
 
Game:
 
Added support for Logitech G29. Please note that all Logitech users need to get the latest drivers from Logitech to have wheel ranges working properly.
 
Implemented Compact HUD which replaces the minimalistic HUD.
 
Added Bigger Grids, allowing tracks to have more than 24 opponents. The maximum number depends on the track and can go up to 100. (SP only for now)
 
Implemented FFB Meter which can be used to check the ffb output for clipping.
 
Implemented FFB Minimum Force which allows player to amplify small FFB forces. This is mostly for players that have the “dead center” problem when driving straight.
 
Implemented FFB Slip effect which simulates when the tires struggle for grip during wheelspin, understeering, sliding, heavy braking.
 
Implemented stationary friction in FFB to solve wheels that rotate by themselves while the car is stationary.
 
Implemented FFB Multiplier per car in the car setup, allowing player to adjust the overall FFB strength for a car individually.
 
Added a new Steering Animation Setting in Vehicle Settings. Player can now set the steering animation rotation to be a custom degree or to match what’s in car setup under steering settings.
 
Added Load/Save in Car setup. Also reorganized the settings a bit.
 
Removed old auto saving of setup when leaving car setup screen and related logic. Car setup will no longer auto save and the unsaved changes will disappear when leaving the game session.
 
Added fuel to car setup.
 
Implemented lap invalidation for wallriding.
 
Fixed some threading exceptions that could trigger a crash.
 
Fixed some camera related rendering thread issues that could trigger a crash.
 
Fixed random crash that could occur when pulling out of pits in single race practice session.
 
Fixed an issue where the game was only seeing the integrated graphics card on laptops with NVIDIA Optimus.
 
Changed fallback null texture format to better support older low end graphics cards that were getting crashes on startup.
 
Fixed an issue where start lights could get stuck on screen on certain occasions.
 
Fixed an issue where the game would spawn the player at an incorrect garage spot.
 
Improved Shadow split calculation
 
Added a potential fix for parts falling off car at race restart.
 
Fixed so that pitmenu, pit window and pit related overlays don’t show up post race.
 
Fixed a crash that could occur while using instant replay.
 
Fixed cars flickering in replay.
 
Changed so ambient sounds for tracking cameras are initialized after the loading is done to fix some wrong calls.
 
Optimized the logic performance.
 
Fixed issue with test drive losing audio when alt-tabbing and going back to the game.
 
Fixed an issue with returning to garage after pause.
 
Fixed cars popping in and out on occasion.
 
Fixed error messages in the new menus appearing as white text on white background.
 
Revised several controller profiles according to the new ffb additions.
 
Added Logitech G29, Fanatec CSR and Thrustmaster T300 F1 Wheel addon profiles.
 
Tweaked keyboard default profile for better steering at higher speed.
 
Fixed issue with ffb gain only being updated on device initialization which meant that changing it in options didn’t change anything).
 
Fixed so wheel range, rev lights and led display are reset when game is closed.
 
Added supplemental controller type so that devices such as shifters and pedals trigger the right dialogue when initialized.
 
Changed so control set evaluation is only done on controller that's not supplemental. This fixes the with wrong control set being selected by pedals etc and removes extra dialogs asking the player if he wants to create a profile for them.
 
Fixed a crash that could occur in driver logic.
 
Fixed a freeze that could occur after the initial track load.
 
Fixed gear damage that was occurring when downshifting on cars with downshift prevention.
 
Changed LiveTimings, Race Monitor and Session Info to be part of the Menu System instead of being static variables/singletons. This is an attempt to clear up some of the mess and to hopefully fix the issue with menu being broken sometimes after session switches.
 
Fixed so “Visible Cars” feature applies on any camera, including free cam.
 
Fixed so only timing and position overlays are disabled when the tv overlay setting is off.
 
Changed so low fuel, push to pass and drs overlays are not shown if the compact data display is active.
 
Fixed a crash that sometimes occurred when bringing up the pit menu.
 
Fixed issue with PitPresets not being shown if they're created mid race through the pause menu.
 
Added menu music and music volume setting in sound options.
 
 
 
Multiplayer:
Added bigger grids in company dedicated servers for testing. We will set up few servers with more than the usual grid size (up to 100) to test and would like you all to join to help us testing.
 
Various potential fixes for a crash that was occurring when switching from qualifying to race in Multiplayer.
 
Increased stack size for game to fix the stack overflow crash that could have occurred when joining MP.
 
Fixed small issue with garage screen not refreshing after session switch in MP (still showed old session type name if player was in the menus during switch).
 
 
 
 
Sounds, Cameras, Physics & AI:
 
AI now better respects track limits.
 
AI now visually use default steering settings for their car. Player’s car under AI control now also uses player’s steering settings.
 
AI cars now properly use the correct Final Ratio for their gearbox on the current track.
 
Updated chase cameras for all so player can feel the car better and be able to see enough of the road ahead
 
FallOffDistances (distance at which sounds can be heard) adjusted so replay volume on TV Cameras are balanced with gameplay volume. Engine sounds now have a longer audible distance
 
Ambient sound samples on old tracks are now starting at random moment in the samples.
 
RoadFeel Effects and Suspension Squeak sound option levels are now set to 40% by default.
 
Helicopter cameras now play a constant Helicopter sound sample (was using a fixed area before)
 
Wind sound sample (open cockpit cars) updated, volume decreased for a better balance in Stereo setups
 
New sound sample for rumblestrips
 
Fuel Estimates adjusted for all cars and tracks
 
FFB Multiplier adjustments for various cars
 
Audi 90 GTO : Massive physics update, cranked idle engine volume to 11
 
Chevrolet Greenwood (Gr.5) : Suspension sounds were missing.
 
Formula RR2: Fixed rearview camera in triple screen

NSU TTS : Fixed a floatiness feeling, AI’s should now be better at standing starts
 
Hockenheim GP : TV camera files updated
 
Indianapolis: merged cut track rules
 
Macau : Tweaked AI lines around the hairpin, Fixed a couple TV cameras that were affected by guardrail / tree objects
