  > The license has been changed to the MIT license. This is more
    permissive than the previous LGPLv2 license and is still
    compatible with the GPL and LGPL. For more background on why we
    decided to make this change please see the following post on the
    mailing list:
    http://lists.freedesktop.org/archives/cogl/2013-December/001465.html
  > GObject introspection support has been greatly improved.
  > Add cogl_kms_renderer_set_kms_fd to make the KMS backend use a
    non-default GPU.
  > Fix a hang in the Wayland backend if it can't find some globals
    that it needs.
  > Add cogl_gst_video_sink_get_natural_size to query a suggested size
    for a Cogl-GST sink
  > Add API to query the EGL and GLX contexts. This is intended to be
    used to make a shared GL context.
  > Fix advertising the deprecated buffer age feature flag on EGL.
  > Add a new non-deprecated feature flag for the buffer age.
  > Fix a bug with allocating textures in Cogl-GST.
  > Fix a bug with the cogl-basic-video-player example where it would
    try to use non-existant mipmaps.
  > Fix selecting the GL driver in the SDL2 winsys.
  > Updates to the MSVC build files.

  # Gnome Bugzilla bugs closed since 1.17.4:

    #724992 - get the opengl context from cogl

  > cogl-gst now ensures that sampled video fragments are always
    pre-multiplied with the alpha component.
  > cogl-gst now has NV12 format support.
  > The cogl-basic-video-player example can now be passed an
    custom gstreamer pipeline description, as long as it contains
    a coglsink element.
  > The -experimental-2.0 pkg-config files now all depend on
    cogl-2.0-experimental instead of cogl-1.0.

  # Gnome Bugzilla bugs closed since 1.17.2:

    #712832 - video-sink: Add NV12 shader support

  # List of changes since Cogl 1.16.2

  > Textures are now allocated lazily. This means the textures can
    optionally be configured with extra API before data is uploaded to
    them.
  > The internal format for textures has been replaced with a simpler
    property to just set the number of components that will be
    required when sampling.
  > Depth writing can now be disabled per-framebuffer as well as on
    the CoglPipeline.
  > The interface typedefs such as CoglTexture, CoglFramebuffer and
    CoglBitmap etc are now defined as void so that it is no longer
    necessary to use type-cast macros when passing them to interface
    methods.
  > Added support for red-green 2-component textures.
  > The cache of GLSL shaders is now garbage collected when it gets
    too large.
  > cogl-path is now split out into a separate library.
  > New function cogl_wayland_texture_set_region_from_shm_buffer to
    update a texture from a Wayland SHM bufffer.
  > The pkg-config files for cogl-gst and cogl-gles2 have new more
    consistent names.
