The Open Toolkit is set of fast, low-level C# bindings for OpenGL, OpenGL ES, OpenAL and OpenCL. It runs on all major platforms and powers hundreds of apps, games and scientific research.  It provides bindings for GLFW windowing, input and a game loop, and is the perfect start for your own game engine.  OpenTK comes with simple and easy to follow tutorials for learning *modern* OpenGL. These are written by the community and represent all of the best practices to get you started.  Learn how to use OpenTK here:  https://opentk.net/learn/index.html  Sample projects that accompany the tutorial can be found here:  https://github.com/opentk/LearnOpenTK  We have a very active discord server, if you need help, want to help, or are just curious, come join us!  https://discord.gg/6HqD48s

BREAKING: Made `NativeWindow` able to run on Wayland (when running on Wayland `NativeWindow` will default to Wayland, use `OPENTK_4_USE_WAYLAND=0` or set the X11 glfw hint to use X11/Xwayland). (@NogginBops)
BREAKING: Change type of `NativeWindow.CurrentMonitor` property from `MonitorHandle` to `MonitorInfo`. (@NogginBops)
BREAKING: Changed EGL bindings to `DllImport` `libEGL` instead of `libEGL.dll` (shouldn't be breaking in most cases). (@NogginBops)
BREAKING: Removed leftover module references to `libGLESv2.dll` (and `opengl32.dll` and `GLESv1_CM`) in `OpenTK.Graphics.dll` which was causing build errors in `net8.0-macos` projects. (these references are never used by OpenTK so they shoudn't be there, this might break something in very specific circumstances)(@NogginBops)
BREAKING: `MathHelper.Lerp` no longer clamps `t` to `[0, 1]` range. (@NogginBops)
API: Upgrade to GLFW 3.4. (@NogginBops)
API: Updated OpenGL bindings to contain the latest definitions without breaking `4.8.2` compatibility (this includes OpenGLES 3.1 and 3.2). (@NogginBops)
API: Add `NativeWindow.MakeFullscreen` method to more seamlessly transition a window to fullscreen. (@NogginBops)
API: Deprecate `Matrix4(d).ExtractProjection`. (@NogginBops)
API: Added `Matrix4(d).ExtractPerspectiveOffCenter/ExtractPerspectiveFieldOfView` to extract projection matrix parameters from perspective projections. (@NogginBops)
API: Added `Matrix4(d).ExtractOrthographicOffCenter/ExtractOrthographic` to extract projection matrix parameters from orthographic projections. (@NogginBops)
API: Add matrix swizzle functions `Matrix2/3/4(d).Swizzle/Swizzled/CreateSwizzle`. (@NogginBops)
API: Added `MouseCursor.PointingHand/ResizeEW/ResizeNS/ResizeNWSE/ResizeNESW/ResizeAll/NotAllowed` standard mouse cursors. (@NogginBops)
API: Added `VectorN.Slerp` (spherical interpolation) and `VectorN.Elerp` (exponential interpolation) functions. (@NogginBops)
API: Added `NativeWindow.AlwaysOnTop` property to set if a window should always be visible. (@NogginBops)
API: Added `NativeWindow.MousePassthrough` property to set if the window should be transparent to mouse interactions. (@NogginBops)
API: Added `CusorState.Confined` to be able to confine the mouse cursor to the window content area. (@NogginBops)
API: Implemented `Matrix3(d).Column1/2/3`, `Matrix4x3(d).Column1/2/3` and ``Matrix3x4(d).Column1/2/3/4` property setters. (@NogginBops)
API: Make `NativeWindow` throw explicit `InvalidOperationException` or `OutOfMemoryException` if `glfwCreateWindow` fails. (@NogginBops)
API: Added a few missing constants to the EGL bindings. (@NogginBops)
API: Deprecate `NativeWindow.CurrentMonitor` property setter. (@NogginBops)
API: Implemented `Matrix2/3/4(d).Transposed/Inverted` for matrix types that where missing them. (@NogginBops)
API: Deprecate `Matrix4d.Scale/RotateX/RotateY/RotateZ/Rotate/Frustum/Perspective`use the `Create*` functions instead. (@NogginBops)
API: Deprecate `EffectSlotInteger.AuxiliarySendAuto` in favor of `EffectSlotBoolean.AuxiliarySendAuto`. (@NogginBops)
FIX: Fix wglDXCloseDeviceNV argument name, from `dxDevice` to `hDecvice`. (@NogginBops)
FIX: All assemblies are now signed. (@RFBomb, @NogginBops)
FIX: Fixed nuget package metadata. (@NogginBops)
FIX: `OpenTK.Graphics` now contains proper debug info, the code is still generated but might improve debug experience. (@NogginBops)
FIX: Fix issue where `NativeWindowSettings.StartVisible=false` with `NativeWindowSettings.StartFocused=true` would create a visible window. (@NogginBops)
FIX: Updated links in README to link to the website tutorial. (@NogginBops)
FIX: Added basic README to nuget packages. (@NogginBops)
FIX: Fix GLFW calling convention when on 32-bit windows, this was causing a StackOverflowException. (@NogginBops)
FIX: Improved a bunch of OpenAL documentation. (@NogginBops)
