+
+  » 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.
+  » YV12/I420 support in cogl-gst is fixed.
+  » Added support for red-green 2-component textures.
+  » The cache of GLSL shaders is now garbage collected when it gets
+    too large.
+  » cogl_framebuffer_push_path_clip is fixed.
+  » 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.
