Nothing too much exciting in this release - just a big pile of bug fixes and a few tweaks to fix some issues that came up with the new animations system in r47. Remember the description of the animations system is still available on the r47 page on the left.
Last build I mentioned I lost the changelog for r47. Instead of editing r47 I've just added the forgotten changelog items to this build. So a couple of these changes were actually in r47, but only made it to this changelog :)
