The phpBB group released version 3.3.2 yesterday. Since one security issue was fixed, an update to that version is a good idea.
I have updated the Do I need to update? page to indicate the tables that are changed in this update. If updating from phpBB 3.3.1, you don’t need to backup any other tables than those shown for the release on this page.
You can see the announcement and get a summary if interested.
phpBB 3.2.11 was also released and contains the security bug fix in 3.3.2, but which was present in 3.2. It’s better to migrate to phpBB 3.3 if you are on phpBB 3.2, but if you can’t you can at least address this security issue.
