+Snapshot 1.11.4 (2012-13-12)
+============================
+The cairo community is pleased to finally announce the long aniticpated
+release candidate for 1.12, 1.11.4, of the cairo graphics library. This
+is the first major update to cairo in over a year and brings a large
+number of new features; undoubtably a few bugs as well.
+
+While many people have contributed and have helped to test the release,
+providing feedback on 1.10 and suggesting improvements, this release
+is the result of a few persevering souls who deserve recognition for their
+outstanding contributions: Andrea Canciani (all round bug fixing,
+performance tuning and master of the gradients), Adrian Johnson (PDF
+supremo) and Uli Schlachter (who stepped forward as maintainer for the
+XCB backend).
+
+Major additions since 1.11.2:
+
+ * cairo_surface_map_to_image API for pixel level access to any surface
+
+ * New antialias hints to control the trade-off between speed and quality
+
+ * A callback pattern, cairo_pattern_create_raster_source, for lazy
+ decoding of image data.
+
+ * cairo_surface_observer_t, a new type of surface to gather performance
+ statistics
+
+ * XCB as a supported backend
+
+ * A rewritten compositor pipeline for performance improvements for, but not
+ limited to, the xlib and image backends.
+ From ION and PineView through to SandyBridge, every machine I have shows
+ across the board performance improvement on the cairo-traces:
