As said in last weekends news post about XBMC 10.0 being imminent: Other XBMC 10.0 features include initial support for OpenGL ES 2.0 to allow the Linux renderer to support embedded devices, SSH file transfer protocol support, a number of new movie/video scrapers have been introduced, an improved video scanner engine, an improved meta-data scraper engine, upgrades against FFmpeg, and much more.
Some of the Linux video fun exciting us in this release is VA-API video acceleration support, OpenMAX video acceleration support, and NEON video acceleration support. While VA-API and VDPAU are the most talked about video acceleration APIs at Phoronix, the OpenMAX video API is used by the NVIDIA Tegra 2 embedded devices and other OpenMAX IL hardware. The NEON video acceleration API targets OMAP3 / ARM NEON hardware. There's also improved VDPAU support with up-scaling and de-interlacing capabilities. Last but not least, there's also improved Linux 64-bit support.
There's also plans already being drafted for XBMC 11.0 on a tighter release cycle. The XBMC 10.0 release announcement can be read at XBMC.org. There's also the 10.0 change-log file.
