We released a new version of Angband yesterday that included version 3.3.1 of the main app. It continues to include 3.06+Borg and 2.4.frogknows as well. Right after we released it, I discovered that 3.3.1 had a serious bug related to not being able to slow monsters, so I had to quickly copy over a patch to fix it. Things should be stable now, but there's probably a 3.3.2 release coming very soon.
If 3.3.2 includes more than just the "slow monsters" patch, we'll probably push it out right away, otherwise I'll have to decide if a release is in order just to make our version numbers match.
