Yepp! There it is: not so many changes but useful improvements and some bug fixes. All you have to do is download the patch package.
I found bugs in SQL queries. The DB_PREPEND constant was not added what results in database errors. Such errors occured only if you have defined such table prefix. See changelog.txt for all changes and improvements.
I have implemented a feature request. Now it is possible to use a new replacement tag for external PHP scripts.
Do not use the spaces in this demo code.
