I've merged connection pooling (DRCP) and Fast Application Notification (FAN) support to PHP 5.3's OCI8 extension. The PHP 5.3 OCI8 code is Beta - in fact, PHP 5.3 itself is still really "Development". (It would be handy to have problems reported before PHP 5.3 goes Production).

He also includes instructions on how to get this new version installed inside of the latest PHP 5.3 snapshot (http://snaps.php.net) to build the new support in.

Version 1.5.4 is primarily a maintenance release. For a list of all changes please see the Change Log. If you are currently running CodeIgniter please read the update instructions.

Included in the list of changes are things like:

• Added some additional mime types in application/config/mimes.php.
• Fixed MSSQL insert_id().
• Fixed a bug in display of queries with characters that would be interpreted as HTML in the Profiler output
• Updated the XSS Filtering to take into account the IE expression() ability and improved certain deletions to prevent possible exploits
