New input system:

-Supports all modern console controllers and possibly some less modern ones such as PC remakes of megadrive pads (untested)

Xbox One
Steam Controller
PS4 (Using the custom DS4Windows drivers available online)

-Allows for simultaneous controller, mouse and keyboard assignment and control
-New input manager, far more customizable than the original allowing two mappings for the same function for both keyboards and controllers.

Performance:

-Mod data is now cached correctly, giving major performance increase for users subscribed to a large number of mods
-Small misc performance fixes to do with UI animation
-Vsync now defaults to off, we recommend leaving it that way if you're having trouble with emulator performance

-Mods now appear in menus correctly when the user is subscribed to > 50 workshop files

"Stretched fullscreen" option implemented

-Off by default
-This setting stretches the fullscreen video output to 16:9

Capped FPS at 120 when vsync is disabled

-Prevents excessive framerates in fullscreen play mode
-Some users with powerful machines were running in excess of 600 FPS, causing overheating

Added "fastest" graphics setting for even lower graphics

-This disables the time of day sun/moon lights and realtime shadows, and sets all textures to lowest LOD
