+	A new cairo release 1.12.12 is now available from:
+
+		http://cairographics.org/releases/cairo-1.12.12.tar.xz
+
+	    which can be verified with:
+
+		http://cairographics.org/releases/cairo-1.12.12.tar.xz.sha1

+		(signed by Chris Wilson)
+
+	  Additionally, a git clone of the source tree:
+
+		git clone git://git.cairographics.org/git/cairo
+
+	    will include a signed 1.12.12 tag which points to a commit named:
+		a201a1169f472e822a66275b7dffe62f241d8ec0
+
+	    which can be verified with:

+
+	Release 1.12.12 (2013-01-31 Chris Wilson <chris at chris-wilson.co.uk>)
+	====================================================================
+	The goal of this release is to fix the synchronisation problems that
+	were exhibited in the SHM transport for cairo-xlib. This cropped up
+	any place that tried to rapidly push fresh pixel data to the X server
+	through an ordinary image surface, such as gimp-2.9 and evince.
+
+	Bug fixes
+	---------
+
+	   Avoid replacing the entire image when uploading subimages
+	   https://bugs.freedesktop.org/show_bug.cgi?id=59635
+
+	   Force synchronisation for scratch SHM image buffers, so that we do
+	   not overwrite data as it is being read by X.
+	   https://bugs.freedesktop.org/show_bug.cgi?id=59635 (also)
+
+	   Fix typos in detecting multisampling for the GL (MSAA) backend.
+
+	   Fix a memory leak in the GL (MSAA) backend.
+
+	   Fix a reference counting bug when mapping a GL surface to an image.
+
+	Complete list of changes from 1.12.10 to 1.12.12
+	------------------------------------------------
+

+	      image: Fix opaque span fills
+	      Mark _cairo_path_is_simple_quad as private
+	      image: And more fallout from c986a73, restore the absent short runs

+	      xlib/shm: Tighten mark-active to the actual CopyArea on the ShmPixmap
+	      xlib/shm: Skip creating new SHM segments if the data is already in the xserver
+	      xlib/shm: Tidy creation of the proxy source for ShmPixmaps
+	      xlib/shm: Tidy up destroying the mempool for a shm block
+	      xlib/shm: Always request a CompletionEvent from ShmPutImage
+	      xlib/shm: Force synchronisation for scratch SHM image buffers
+	      xlib/shm: Simplify uploading of SHM image data
+	      xlib/shm: Appease the compiler for a 'maybe used uninitialised' variable
+	      configure: Include X11.h before testing for usability of Xrender.h
+	      xlib/shm: Clarify testing of seqno
+	      xlib/shm: More clarification of seqno required
+	      perf: Synchronize before stopping the timers
+	      image: Add a reference for the clone's parent image
+	      test: Refresh refs for aa noise following reduction of the 2-stage compositing
+	      1.12.12 release
+
+	Henry Song (5):
+	      gl: Don't query the display when checking if the context changed
+	      gl/msaa: Fix a memory leak in _clip_to_traps
+	      gl: Fix typos in multisampling detection
+	      gl: Use GL_ALPHA textures for CAIRO_CONTENT_ALPHA glyph caching
+	      gl/msaa: Don't emit alpha when emitting vertices
+
+	Martin Robinson (1):
+	      gl/msaa: Add a fast path for fills that are simple quads
