OpenTK

Made nuget package builds "deterministic". (@NogginBops) Fix assembly versions to match OpenTK release version. (@NogginBops)

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) FIX: Fix GLFW calling convention when on 32-bit windows, this was causing a StackOverflowException. (@NogginBops) FIX: Improved a bunch of OpenAL documentation. (@NogginBops)

FIX: Fixed issue where setting NativeWindow.WindowState = WindowState.Normal while fullscreen would not exit fullscreen. (@Th3Dilli) API: Added NativeWindow.FramebufferSize, NativeWindow.OnFramebufferResize, and NativeWindow.FramebufferResize to be able to properly get the framebuffer size of the window (useful on macos where framebuffer size is not equal to client size). (@NogginBops) API: Added GameWindowSettings.Win32SuspendTimerOnDrag propery that allows the internal timer to be suspended while the window is moved or resized. Without this dragging the window will cause an abnormally large time delta since the last frame. (@MV10) API: Made NativeWindowSettings.Size obsolete in favour of NativeWindowSettings.ClientSize (NativeWindowSettings.Size has always set the client size of the window, this namechange just makes this clear). (@MV10) API: Added ability to override OpenAL and OpenCL native library search path by setting OpenALLibraryNameContainer.OverridePath or OpenCLLibraryNameContainer.OverridePath. (@NogginBops) API: Added NativeWindowSettings.AutoIconify and NativeWindow.AutoIconify property to control if the window gets minimized if it loses focus while fullscreen. (@MV10) API: Added missing enums to GetPName. (@BoyBaykiller) FIX: Fixed an issue where creating a NativeWindow on wayland would freeze in the constructor. (@Th3Dilli) BREAKING: Re-implemented Box2/3.Inflate to work like System.Drawing.Rectangle.Inflate. The old behaviour can be found using Box2/3.Extend, as the previous obsoletion message stated. (@MV10, @NogginBops) Add example of how to implement IBindingsContext in the documentation comments on IBindingsContext. (@utkumaden) Internal changes to make the build system simpler and easier to modify. (@NogginBops) Internal changes from Math to MathF where appropriate. (@MV10)

API: Added NativeWindow.HasTransparentFramebuffer to be able to check if a transparent framebuffer was created successfully. (@NogginBops) API: Added missing enum entries in OpenCL.ContextProperties. (@NogginBops) FIX: NativeWindowSettings.StartVisible = false has been fixed and should now work as expected. (@NogginBops) FIX: Fixed issue where JoystickState.GetAxis returned buttons instead of axes. (@NogginBops) FIX: Fixed issue where self-contained dotnet publish would break due to duplicate libglfw.so files. (@Th3Dilli) FIX: Setting NativeWindow.WindowState will now be reflected in OnResize event caused by it. (@NogginBops) FIX: GameWindow.UpdateTime is now correctly updated, fixing an issue that first appeared in 4.7.1. (@NogginBops) FIX: Fixed typo in deprecation message for GameWindow.RenderFrequency. (@postmeback)

BREAKING: Renamed the OpenTK.OpenAL assembly to OpenTK.Audio.OpenAL to match the namespace. (@NogginBops) BREAKING: Make OpenAL extensions nested classes of AL and ALC instead of being namespaces to more closely match the OpenGL bindings. (@NogginBops) BREAKING: Removed AL.BindBufferToSource, AL.GetSourceState, AL.GetSourceType, and ALC.GetAvailableSamples that doesn't exist in the OpenAL API (use AL.Get* and ALC.Get* instead). (@Khhs167, @NogginBops) BREAKING: NativeWindow.Location, NativeWindow.Size, and NativeWindow.Bounds now correctly refer to the external size and location of the window. (@NogginBops) BREAKING: Removed a few functions marked [Obsolete] since at least 4.7.2 but some even older. (@NogginBops) BREAKING: Removed OpenTK.Core.Utils.Swap<T>, use MathHelper.Swap<T> instead. (@NogginBops) API: Rename Box.Inflate to Box.Extend, and mark Box.Inflate as obsolete so we can change the behavior of Box.Inflate in future versions. (@NogginBops) API: Added GameWindow.TimeSinceLastUpdate() and GameWindow.ResetTimeSinceLastUpdate() which are useful when dealing with the modal move/resize loop on windows. (@NogginBops) API: Added NativeWindow.RawMouseInput and NativeWindow.SupportsRawMouseInput for activating raw mouse input. (@NogginBops) API: Added opt-in preliminary GLFW Wayland support through the environment variable OPENTK_4_USE_WAYLAND (it's broken when used with GameWindow or NativeWindow in this version). (@NogginBops) API: Updated the GameWindow run loop to be much more accurate. Exposed GameWindow.ExpectedSchedulerPeriod to tell OpenTK how accurate Thread.Sleep can be expected to be (this defaults to good defaults for Windows, Linux, and macos). (@NogginBops) FIX: Cleaned up some internal OpenGL definitions (doesn't change any bindings). (@BoyBayKiller) API: Expose MouseCursor.StandardShape as public. (@NogginBops) API: Add VectorNi.EuclideanLengthSquared. (@NogginBops) FIX: Added helpful exception message to NativeWindow when running with trimmed assemblies with a workaround for the issue. (@NogginBops) FIX: Fixed an issue where starting NativeWindow as a fullscreen window and then going to a normal window would throw an exception. (@NogginBops)

FIX: ToString() on all math types no longer throw NullReferenceException. (@NogginBops)

BREAKING: Changed the default value of NativeWindowSettings.Flags from ContextFlags.Default to ContextFlags.ForwardCompatible for better out of the box macos support. (@NogginBops) API: Added NativeWindowSettings.TransparentFramebuffer and NativeWindowSettings.VSync. (@NogginBops) API: Component-wise Lerp methods for float and double vector types. (@g7ChoGXh) API: Implemented IFormattable for most OpenTK.Mathematics types. (@g7ChoGXh) API: Add bindings for EXT_fragment_shading_rate. (@BoyBaykiller) API: Added casts from Vector2i and Vector2 to System.Drawing.Point/System.Drawing.Size and System.Drawing.PointF/System.Drawing.SizeF respectively. (@NogginBops) API: Added missing entries in SizedInternalFormat. (@BoyBaykiller) API: BinaryFormat now contains the ShaderBinaryFormatSpirV enum value. (@NogginBops) FIX: Many fixes related to NativeWindow.WindowState. Most notably, going from fullscreen to maximized and back works correctly. (@NogginBops) FIX: MonitorInfo.WorkArea now gives the correct values. (@utkumaden) FIX: Spelling and formatting corrections in documentation. (@sg-wizard-maker) FIX: Math types now change their formatting when CurrentCulture is changed. (@g7ChoGXh) FIX: Matrix4x3/Matrix4x3d now print their final row. (@NogginBops) FIX: On Windows, setting GameWindowSettings.UpdateFrequency and GameWindowSettings.RenderFrequency should be more accurate. For details see documentation for GameWindow.Run(). (@NogginBops) The OpenTK solution should now build directly in Visual Studio with no need to run build.cmd any more. (@NogginBops)

• If the update loop gets too far behind it no longer tries to make up for lost time. This was typically caused by resizing the window, and or closing the lid of a laptop. (@daerogami)

• OpenTK no longer put an upper limit on the System.Runtime.CompilerServices.Unsafe package. (@NogginBops)

• Fixed so NativeWindowSettings.DepthBits and NativeWindowSettings.StencilBits actually affect the resulting backbuffer format. (@NogginBops)
