Python 3.5 is no longer supported from this version.

New Features

* Experimental: New simple 2D text writer
* Various smaller improvements
* F11 now toggles fullscreen mode by default
* Window modules are now fetched from `moderngl_window.WINDOW_CLASSES` as a fallback. This is necessary in some enviroments.
* Absolute paths will now bypass all registered resource directories and load the specified file directly.

Bug Fixes

* Varying names can now be passed in when loading a program. Since the auto detection of out attributes is far from perfect this can be needed for more complex shaders.
* Missing python 3.9 classifier in setup.py
* SDL2 window should now also process since change events
* GLFW: Fixed some incorrect key mappings
* Fixed an issue with timers causing the first frame to have negative frame time
* Fixed a pixel scale issue in the imgui integration. This was especially an issue with tiling window managers

Python 3.11 support

Expose headless/standalone flag
