Unreleased

  • Add PossiblyCurrentContext::make_not_current_in_place(&self) for when Send capability of NotCurrentContext is not required.
  • Add NotCurrentContext::make_current_surfaceless(self) and PossiblyCurrentContext::make_current_surfaceless(&self) in the Cgl implementation to allow the use of surfaceless contexts on MacOS.

Version 0.32.1

  • Fixed EGL's Device::query_devices() being too strict about required extensions.
  • Fixed crash in EglGetProcAddress on Win32-x86 platform due to wrong calling convention.

  • Added support for DrmDisplayHandle in EGL's Display::with_device() using EGL_DRM_MASTER_FD_EXT from EGL_EXT_device_drm.
  • Properly set up OpenGL-specific stuff on the NSView, instead of relying on Winit to do it.

  • Fixed wrong amount of rects committed in Surface::swap_buffers_with_damage with EGL.
  • Added missing Eq, PartialEq, and Hash impls for surface::Rect.

Version 0.30.2

  • Fixed robust context creation with EGL.
  • Moved to stable version of wayland-sys.
  • Allow offline renderers with CGL.
  • Fixed an error when compiling the EGL backend with only one of Wayland and X11 enabled.

Version 0.30.1

  • Added new glutin-winit crate to help bootstrapping new glutin with winit.
  • Added EGLDevice wrappers for EGL.
  • Added EGL dependent api to make a context current without a surface.
  • Added supports_transparency on GlConfig.
