Downloadable ZIP of latest trunk is via a link at the bottom of that page.

The trunk is pretty stable actually, and is more bug free than the latest release usually.

You are better off setting up a subversion client and “checking out” a copy of the code. You can then keep up-to-date on changes in the core with the click of a button.

Search the forum for info on using SVN to checkout a copy.

A lot has changed, the best thing to do is to trawl through the changelog on the Trac site. Only a couple of things have changed dramatically, how views works is one.

BB_Query is in the latest trunk in bb-includes/classes.php
