in this revision, you will mostly find some fixes regarding animation setup. The rotation interpolation scheme has been replaced with a new one that is much more consistent when interpolating key frames. In addition to that, you can now click and drag the key frames (from the small handles on the top of the lines) having more control on the setup.
There are also some network rendering improvements. Some bug fixes where a client was continuing to contribute. Also, in the client configuration, the user can now specify a range of IP addresses where the server might be located. Even more, the server address (and range) can now be left completely blank and the client will automatically look for a server (in LAN) to get a render task. In fact, this is the recommended approach and your clients can start working immediately after installation without any setup at all.

Apart from the above, there were some small improvements regarding the inputs in the license form and a fix for IES lights that were being "clamped" too soon with respect to viewing angle.
Edit: updated to revision 452 with needed fix for opening IES file and various fixes related to photon mapping (improving consistency and removing black "dots" with BSD engine).
Edit: updated to revision 453 with fix for opening IES File in point lights and auto detection of server in network rendering. There is also an improvement for Viewport fixing problem with distant objects becoming invisible by automatically setting up depth range.
