* OpenTK no longers alters the dll search path be default on windows platforms. Separate folders for `x86` and `x64` dlls can now be optionally turned on by using `ToolkitOptions.SetWindowsDLLPathAnyCPU = true`, see documentation comment for more details. (@NogginBops)
* New feature that allows you to use virtual keys on windows. This can be toggled on using `GameWindowFlags.UseVirtualKeys`. See for more details. (@tyronx)
* Deprecated `Vector3 Transform(Matrix3 mat, Vector3 vec)` (right multiplication) because of a bug meant this function was doing a left multiplication. Instead two new functions `TransformRow` and `TransformColumn` that handle the left and right multiplication correctly. (@NogginBops)
* A lot of enum entries where added to enums where they where missing. For example `SizedInternalFormat` now contains all allowed formats and `GetTextureParameter` now contains `TextureMaxAnisotropy`. (@NogginBops)
