This update took us longer, since we were working on bigger changes that needed time to mature enough to be released with quality in mind.

DirectX 11
We have switched from DirectX9 to DirectX11. The benefits are improved performance, future proofness and a good step towards modernizing the game engine core. The downside is that DirectX 11 will not run on Windows XP any more.

Features:
Moved some calculations to the GPU, speeding up the flexmeshes considerably
Implemented realistic Electronic Stability Control with multiple switchable configurations: Use CTRL+Q to switch. The Hirochi Sunburst is currently the only vehicle modern enough to have ESC support.
Small startup time improvement
Added force-feedback defaults to Fanatec and T500RS wheels
New main menu background images replacing the blurry video - Higher quality and more appealing
Added new vehicle Lua API: getYawAngularVelocity, getPitchAngularVelocity, getRollAngularVelocity
Added brakePressureDelay to simulate delay of air brakes on heavy trucks
Changelogs in the start menu and the info tab
Improved debug visualization for sounds.
Windows 10: Tested and found to be working well, fixed version reporting


Input:
Mouse wheel, axes, and some buttons can be bound now, enabling you to have mouse steering
Improved bindings: now faster and more direct: calling VLua, ELua, JS or TS directly
G27 steering wheel RPM LEDs working
Fixed setting bindings of high-end controllers that can fire rapid events (such as Fanatec CS or Saitek X-55)
Fixed inability to add and save bindings after the last one has been removed
Right mouse button "look" is now a binding like the rest (and can be replaced by mouse steering, accelerate & brake, and many others)
Add filtering options to mouse controls (deadzone, linearity, inversion)
Show controller name next to axis/button identifier when editing a binding (to help those with many controllers connected at the same time)
Show device type icon (keyboard, gamepad, etc. icons) next to most binding assignments
Minor GUI improvements in Controls menu to improve usability
"Advanced Functions" mode now also disables certain hotkeys used for debugging and alike.


Bugfixes:
Vehicle loading optimized making it 3x faster
Using average wheel speed for speedometer instead of the speed of one of the wheels
Fixed physics core loosing beams under rare circumstances
