Valgrind 3.3.0 hit the streets a couple of days ago and I did not notice! In the unlikely case you haven't heard of this amazing application before, it is a suite of tools for debugging and profiling programs. It is one of the most useful programs I have ever used, actually.

IMO, the best thing about this release is that Helgrind is back. The long-awaited synchronisation errors detector is working again after a few years out of the package. That's so sweet! :-)

I'm going to get it compiled on my Linux box right away (it is extremely platform dependent and it only works on Linux).
