libpixman 0.28.0 is available, see http://www.cairographics.org/releases/
A conveniently placed changelog would have been great to include: http://lists.x.org/archives/xorg-announce/2012-November/002094.html
FWIW, the majority of the changes have already been merged in.
http://lists.cairographics.org/archives/cairo-announce/2012-December/000208.html libpixman 0.28.2 released. Log: Benjamin Gilbert (1): Fix thread safety on mingw-w64 and clang Joshua Root (1): Fix undeclared variable use and sysctlbyname error handling on ppc Stefan Weil (1): Always use xmmintrin.h for 64 bit Windows Søren Sandmann Pedersen (2): Post-release version bump to 0.28.1 Pre-release version bump to 0.28.2
PS: question , is it able to use SSE2 code path even on windows 32bit build ? we have real performance measurable improvment from the pixman improve ? http://lists.cairographics.org/archives/cairo-announce/2013-January/000210.html Libpixman 0.29.2 released A new pixman release 0.29.2 is now available. This is the first development snapshot leading up to a stable 0.30.0 release. News in this release: * Assembly optimizations for the Raspberry Pi and other ARMv6 chips [Ben Avison] * Comprehensive support for high-quality image resampling filters [Søren Sandmann] * Improved precision for matrix arithmetic [Siarhei Siamashka] Other news include optimizations in the SSE2 backend [Chris Wilson], in the MIPS DSPr2 backend [Nemanja Lukic], and in the generic C backend [Siarhei Siamashka], plus a number of bug fixes and improvements to the test suite.
The intention is to update gradually to make bisection easier

Actually, I confused this bug with bug 836171
This gives a bunch of improvements to blitting performance on armv6 along with some x86 improvements.
there is a way to discover when azure going on fallback in cairo ?
