Since tome3 is taking a while some new features are being tested in a new branch of tome2: 2.3.x, which is available in the nightly compiles here. These are only for windows; others will have to compile the cvs themselves, which hopefully won't be too hard.
The most important new feature is that the internal angband 'skills' have been removed. This will require a lot of testing, so please try several all classes, especially fighting mages and bards, which are the classes that probably will benefit most from this. See changes.txt for other changes.
