Re: bbPress 0.9.0.1 released
For those that already downloaded 0.9 there is only one file that changed (pluggable.php)
https://trac.bbpress.org/changeset?old_path=tags%2F0.9&old=1399&new_path=tags%2F0.9.0.1&new=1403
If you already had 0.9 you only need to replace these two files to move to 0.9.0.1 (and the second is just for the version number change)
