We’re now in the preparation phase for the 3.5.0 release of Valgrind, which will be the first release with Mac OS X support. We’ve absorbed some Mozilla culture in the Valgrind development process — we’re now using Bugzilla much more effectively. We have 17 open blockers (and 18 closed blockers), and 41 open “wanted” bugs (and 7 closed ones). Any contributions towards fixing these bugs is most welcome! We’re hoping to release in early August.
