• WheelController can now be used with 'Max Spring Length' of 0.
• Improved wheel depenetration and added depenetration settings to WheelController.
• Reworked FlipOverModule and added instant flip over.
• Fixed ReorderableList crashing Unity when exiting play mode. Only Unity 2021.1.
• Added support for NetworkRigidbody to MirrorMultiplayerVehicle. Collisions now work in multiplayer too. If NetworkRigidbody is not attached vehicle will be kinematic as before the update.
• Fixed multiple issues with powertrain inertia.
• Fixed WheelController not applying any force to surface when bottoming out and spring strength is 0.
• Fixed WheelController spring gizmos being drawn in wrong place.
• Fixed NaN issue when max spring length is set to 0.
• Fixed VehicleComponent not having Enable() called when entering play mode resulting in some modules not initializing properly.
• Fixed ApplyForceToOthers not applying correct friction force.
• Fixed missing trees in the Racetrack demo scene.
• Fixed transmission going into neutral after car stops moving while 'Require Shift Input' selected.
• Added ''Apply Brakes When Speeding“ option to CruiseControlModule.
• Added ability to apply throttle manually while cruise control is active.
• EngineComponent.RPMPercent now returns RPM percentage in relation to rev limiter instead of the solver maximum RPM allowing it to actually reach 1.
• Modified TransmissionComponent to allow gear skipping at full throttle.
• Other minor bug fixes and improvements.

• Moved NVP_NUIEditor and NVP_NUIPropertyDrawer to Editor sub-folder to avoid issues if assembly definition files are removed.

• Removed requirement for .NET 4.x.
• Fixed the import issues introduced with the previous version.

• Added .asmdefs to improve compilation times. With the upcoming updates all NWH assets will feature asmdefs.
• Major changes to the skidmark system for increased performance and stability. Skidmark settings are now adjustable at runtime.
• Rework of CVT transmission.
• Added peak power and torque (and respective RPM values) to the EnginePowertrainComponent and added a readout in the editor. Default clutch slip torque is now set in relation to peak engine torque.
• Fixed modules initializing twice.
• Fix brake smoothing not being used.
• Fixed left and right enter-exit points being swapped inside the vehicle setup wizard.
• Fixed steering deadzone when returnToCenter is disabled.
• Fixed wheel damage not working properly.
• Fixed WheelController issue where the longitudinal force coefficient would increase the actual force applied instead of increasing the maximum tractive force, resulting is higher power output than what is generated by the engine when value of >1 was used.
• Fixed WheelController “ApplyForceToOthers” option applying excessive lateral force to the target object.
• Fixed NRigidbody substeps get initialized to 1 in all cases. This affects only standalone WheelController setups since substeps in NVP2 are set through the VehicleController which overwrites the initial value.
• Fixed WheelController Visual transform scale affecting the Rim Collider scale.
• Upshift RPM of the TransmissionComponent is now limited to a value lower than the engine rev limiter RPM. This prevents issues with vehicle not upshifting when target upshift RPM is too high.
• Updated clutch settings on the Semi truck to prevent stalling when going from 1st to reverse and vice versa due to slow clutch release.
• Other minor bug fixes and improvements.

• Fixed NRigidbody throwing an error when Rigidbody rotation constraints are used.

• Fixed turning off low beam lights while braking resets brake lights.
• Added “Require Camera Rotation Modifier” and “Require Camera Panning Modifier” options to SceneInputProviders, mainly for use with touch screens where modifiers are not needed. Enabling these options makes cameras able to rotate/pan without pressing additional buttons.

• Restructured the asset to prevent errors when trying to import multiple NWH assets in the same project.
• Fixed terrain texture issue when the vehicle goes over the edge of a terrain.

• Improved Cruise Control by adding “Deactivate On Brake”.'
• Fixed a bug with powertrain that resulted in engine being too hard to stall.

• InputProviders have been split to SceneInputProvider and VehicleInputProvider where SceneInputProvider handles scene-related input (camera controls, vehicle switching, character movement, etc.) and VehicleInputProvider handles only vehicle-related input (steering, throttle, brakes, etc.).
• Some parts of the asset are now shared between DWP2 and NWP2 making the two assets compatible and reducing the code duplication.
• Fixed issue where blinkers and hazards could be active at the same time.

• Fixed unneeded using directives introduced in 1.1 preventing the build from finishing successfully.
• Added “Hold To Keep In Gear” option to the transmission. This makes the transmission H-shifter friendly. When the option is enabled an input has to be held for the transmission to stay in corresponding gear, otherwise it goes to neutral.
• Added all available axis options to SteeringWheelInputProvider.
• Removed shift ban timer (delay between shifts) from manual transmission which would get interpreted as the gearbox not receiving input.

• Improved ImputSystem support and made InputSystem default input method.
• Renamed “NewDesktopInputProvider” to “InputSystemProvider” to prevent confusion.
• Improved InputSystem with additional, optional bindings: CameraRotation, CameraPanning, CameraRotationModifier, CameraPanningModifier, CameraZoom, FPSMovement and ToggleGUI. This allowed for removal of all the hard-coded inputs in the asset code and all the input now goes through InputProviders.

• Implemented 'GearShift' class which contains data about the currently occuring gear shift and is used by 'OnShift', 'OnUpshift' and 'OnDownshift' events.
• Renamed Input.AutoSettable to Input.AutoSetInput since the old name was causing confusion.
