+Release 1.4.4 (2007-04-13 Carl Worth <cworth@cworth.org>)
+=========================================================
+This is the second update release in cairo's stable 1.4 series. It
+comes just less than a month after 1.4.2. The changes since 1.4.2
+consist primarily of bug fixes, but also include at least one
+optimization. See below for details.
+
+Of all the work that went into the 1.4.4 release
+
+There have been lots of individuals doing lots of great work on cairo,
+but two efforts during the 1.4.4 series deserve particular mention:
+
+Internal cleanup of error handling, (Chris Wilson)
+--------------------------------------------------
+Chris contributed a tremendous series of patches (74 patches!) to
+improve cairo's handling of out-of-memory and other errors. He began
+by adding gcc's warn_unused_attribute to as many functions as
+possible, and then launched into the ambitious efforts of adding
+correct code to quiet the dozens of resulting warnings.
+
+Chris also wrote a custom valgrind skin to systematically inject
+malloc failures into cairo, and did all the work necessary to verify
+that cairo's performance test suite runs to completion without
+crashing.
+
+The end result is a much more robust implementation. Previously, many
+error conditions would have gone unnoticed and would have led to
+assertion failures, segmentation faults, or other harder-to-diagnose
+problems. Now, more than ever, cairo should cleanly let the user know
+of problems through cairo_status and other similar status
+functions. Well done, Chris!
+
+More malloc reduction, (Mathias Hasselmann)
+-------------------------------------------
+After 1.4.0, Behdad launched an effort to chase down excessive calls
+to malloc within the implementation of cairo. He fixed a lot of
+malloc-happy objects for 1.4.2, but one of the worst offenders,
+(pixman regions), was left around. Mathias contributed an excellent
+series of 15 patches to finish off this effort.
+
+The end result is a cairo that calls malloc much less often than it
+did before. Compared to 1.4.2, 55% of the calls to malloc have been
+eliminate, (and 60% have been eliminated compared to 1.4.0). Well
+done, Mathias!
+
+Other improvements since 1.4.2
+------------------------------
+• Centralize mutex declarations (will reduce future build breaks),
+  (Chris Wilson)
+
+• Reduce malloc by caching recently freed pattern objects (Chris
+  Wilson)
+
+• Fix some broken composite operations (David Reveman)
