Linux kernel 2.6.33-rc3 has been released by Linus post holidays and it's getting slimmer and slimmer, mostly due to long holidays since new year. What i have seen on this version is that it may not as interesting as previous release, since most people were busy with spending time on their holidays, but we should also think about the distribution of people who contributed to this project. There are more than 1000 people working on Linux kernel project and on each release, they might want to put their effort into the main kernel tree, which is done at the merge window (usually takes time after the release of final version of a Linux kernel and before 2.6.33-rc1 gets released).
KernelNewbies still didn't have the brief summary yet, probably waiting for one or two RC before they considered it to be stable enough to be put online and read by public. Here's the 2.6.33-rc2 announcement by Linus on LWN.
