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
[S?ren 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.
