Installed Angband 3.3.2 on the server last night.  There's been a fair number of changes:

Angband 3.3.0 release notes (gives a good summary of the 3.3 changes)
Angband 3.2.0 release notes (summarizes the 3.2 changes)
Angband 3.1 beta release notes (the 3.1 changes)

At some point I need to write a new player's guide to the mage class.
