Today NVIDIA has updated its standalone VDPAU library, libvdpau, which is now at version 0.3. This library update supports versioning to the drivers, configurable install directory support, libvdpau_trace, and documentation updates. The libvdpau 0.3 release announcement can be read on xorg-announce.
Separately, Splitted Desktop Systems today made available an update to libva. Splitted's libva allows the VA-API acceleration API to be exposed atop their VDPAU and XvBA back-ends. It was just at the start of the month that AMD's XvBA finally became usable on Linux via this VA-API interface. There is no change-log for today's release, but the libva_0.31.0-1+sds8 release should provide a few fixes. There's nothing real exciting though to be expected. The package can be downloaded from this directory.
