Cogl 1.7.4 2011-07-20
===============================================================================
• List of changes since Cogl 1.7.2
» Optimize pipeline unparent operation using embedded lists instead
of using GList API.
» Remove the old matrix operation code we had before pulling in the
mesa based code, and flatten all our matrix utilities back into one
maintainable file.
» Expose cogl_framebuffer_get_red/green/blue/alpha bits to query
the precision for a framebuffer's color channels.
» Numerous reference manual updates
» Fix some memory leaks in CoglPipeline that weren't captured in
bugzilla.
» Fix some EGL winsys issues that weren't captured in bugzilla.
» Switch to dynamically loading libGL, libGLESv2 or libGLES[v1]_CM
at runtime so it's possible to distribute a libcogl that can choose
to work with any of these at runtime. This can simplify packaging
on distros that have numerous packages that provide a platform
specific GL/GLES driver and certainly helps during the development
process when evaluating the pros-and-cons of different drivers for
a given platform.
» Clean up lots of inconsistencies with platform specific APIs, so
we follow the naming convention of cogl_<platform>_object_method.
» Remove cogl_set_default_context from experimental 2.0 api, since
we are aiming to remove the default context for 2.0
» Ensure the experimental 2.0 reference manual gets a unique
DOC_MODULE name so that distro's trying to package cogl don't end
up installing the 1.x and 2.0 manuals to the same location
» Add a program cache for the GLSL backend, a bit like we have for
the ARBfp backend. This can be a big boost in performance for some
apps depending on your platform.
» Adds dither_enable getter and setter API for CoglFramebuffer so
that Clutter doesn't need to use the GL API directly when picking.
We need to get to the point where Clutter doesn't need to link
against libGL directly so Clutter can take advantage of runtime
driver selection by Cogl.
» Use MESA_pack_invert extension in cogl_read_pixels to avoid
needing to manually flip pixel data read in bottom-up order to a
top-down order.
» Fix the hello example to actually clear the framebuffer at the
start of the frame instead of unintentionally relying on the driver
to have cleared the framebuffer.

https://bugzilla.gnome.org:
#652514 - CoglPipeline could embed the list nodes for the
children directly in the CoglPipeline struct
#654440 - _cogl_winsys_context_init crash
#654718 - clutter 1.6.16 compile issues
#654593 - dlopening an unversionaed Shared Object is illegal.

Cogl 1.7.2 2011-07-01
===============================================================================
• List of changes since Cogl 1.7.0
» Add an example program to draw a 3D crate
» Add experimental API to get and set the viewport on a framebuffer
without going through the implicit context.
» Add API to select the winsys backend without having to use an
environment variable.
» Various documentation fixes.
» Add winsys-specific typesafe APIs to replace the old
cogl_renderer_handle_native_event functions.
» Rename platform-specific APIs so that we consistently have
cogl_<platform>_symbol_name instead of cogl_symbol_name_<platform>.
» Fixed building against GLES.
