Notes
-----

   o This is a development release of Clutter 0.9 leading towards the
     1.0 stable cycle. It is the second release candidate for the 1.0.0
     release: the Clutter high-level API is to be considered frozen, as
     well as the COGL low-level API.

   o This version is fully API and ABI incompatible with the previous
     0.8 releases.

   o This version is parallel installable with Clutter 0.8.

   o Installing this version will overwrite the files from the
     installation of a git clone of the current development
     branch (master).

   o Bugs should be reported to: http://bugzilla.o-hand.com

What's new in Clutter 0.9.6
---------------------------

    o Allow the manipulation of the actor's transformation matrix, so that is
      is possible to apply additional transformations in a way that is
      compatible with the transformations already applied by the scene graph.

    o Fix a race in the X11 backend that happened between resizing the stage
      drawable and the call to glViewport().

    o Merge the cogl-journal-batching branch; this branch implements batching
      the geometry of the elements of the scene graph before sending it to
      OpenGL, thus minimizing the number of state changes and improving the
      overall performance of Clutter-based applications.

    o Add more debugging states for Clutter and COGL, which allow the developer
      to track the state of the journal; to check the VBO fallback paths; to
      disable picking for reliable profiling; to disable software-side matrix
      transformations in favour of the driver/GPU ones.

    o Improve the ability to "break out" of COGL by using gl_begin/gl_end
      semantics; applications that drop into raw GL are, though, ignoring all
      the caching performed by COGL and might incur in performance issues.

    o Fixed the :load-async and :load-data-async properties of Texture by
      removing the unneeded G_PARAM_CONSTRUCT flag.

    o Added an initial migration guide that shows the porting process from
      older releases of Clutter to the 1.0 API; the first chapter deals with
      the migration from ClutterEffect to the new implicit animations API.

    o Fixed MT-safety for the master clock.

Many thanks to:
