+Release 1.8.6 (2008-12-13 Chris Wilson <chris@chris-wilson.co.uk>)
+=========================================================
+The cairo community is pleased to announce the 1.8.6 release of the
+cairo graphics library. This is the third update to cairo's stable
+1.8 series and contains a small number of bug fixes (in particular a
+few fixes for failures of cairo 1.8.4 on Quartz and PDF, and build fixes for
+a couple of backends). This is being released just under a month after
+cairo 1.8.4.
+
+We recommend that everyone using cairo upgrade to 1.8.6.
