From what I am being told, it’s going to be awhile before an official release of bbPress will work with with WP 2.6 because of the radical cookie changes. Most certainly not the 0.9 branch.

There is a version of bbPress in the trunk that supposedly will work with WP 2.6 but that is definitely not recommended for the average user.

Stick with 2.5.1
