Topic: PunBB 1.3RC2 is out
Most significant 1.3 RC to 1.3 RC2 changes:
New layout: markup, CSS, language files updated, markup helper functions added.
Added split/merge topics functionality.
Added a "database revision number" to the code. This feature provides a way to track whether the database needs to be updated or not.
Added constants to various included files to be used to indicate whether a certain file has been loaded or not, removing the need to use include_once/require_once.
Added global DST option and the default email setting for new users.
Search (searches are now case-insensitive), extern.php, URL rewriting improved.
More helpers added to the DB layer and used everywhere in the forum.
Got rid of extras folder: install and db_update moved to admin; README, COPYING and .htaccess.dist added to the forum root.
Added phpDoc comments to the start of every PHP file, replacing the existing GPL notice.
Lot of hooks added.
You may also check it out from Subversion repository.
UPDATE: PunBB 1.3 RC2 demo is available at http://punbb.informer.com/demo/punbb13rc2/ (DB is automatically restored every 2 hours from the SQL dump).
Please, report bugs in 1.3 core talk forum.
PS: Official extensions may not work correctly now and need to be updated for the new 1.3 RC2 markup.
This will be done in a week or two.
