The Open Toolkit library 1.1.4

OpenTK 1.1.4 was released on 21 July 2014.

Download: binaries - source - NuGet.

This release resolves a number of identified issues, adds experimental support for Linux/KMS and synchronizes the OpenGL and OpenGL ES bindings with the July 2014 Khronos specifications.

Changelog:

  1. Fixed a memory leak in OpenGL functions accepting a string array.
  2. Fixed an issue where MakeCurrent() might fail on Linux/X11 when using the Nvidia closed-source drivers.
  3. Fixed an issue where GameWindow might remain open on Linux/X11 after calling Close() or Dispose().
  4. Fixed a potential crash on Mac OS X systems without hardware acceleration (e.g. virtual machines).
  5. Fixed function parameters for the OES_byte_coordinates extension.
  6. Fixed an issue where OpenTK would always perform a full rebuild even when a partial rebuild could work.
  7. Fixed all compilation warnings on VS2013 and Mono 3.4.0.
  8. Improved OpenGL and OpenGL ES documentation on 'count' parameters.
  9. New platform: Linux/KMS. You can now run OpenTK applications on a Linux terminal without an X11 display server.
  10. New OpenGL ES extensions:
    • ANDROID_extension_pack_es31a

OpenTK 1.1.4 is backwards compatible with 1.1.3. Users of previous versions are strongly encouraged to upgrade.

Known issues

  1. The SDL2 backend has a number of limitations compared to the native platform backends. In particular, SDL2 does not support:
    • OpenTK.GLControl. OpenTK will automatically switch to a native platform backend instead.
    • DisplayDevice.ChangeResolution() without a fullscreen INativeWindow.
    • Switching between WindowBorder.Fixed and WindowBorder.Resizable.
    • High-resolution mouse input. Additionally, it is limited to a single keyboard and mouse device.
  2. OpenTK.Input.GamePad.SetVibration is currently not implemented. This API will be implemented in a future release.
