PHP Version: 5.3.29 (Zend: 2.3.0) PHP Memory Limit: 128M
Database: MySQL 5.5.40-36.1
I just recently upgraded from ZC153 to 154
If I recall there was a difference in a db file as I ran winmerge on all the files before upgrading. But I don't recall which one it was, it wasn't under any of the admin folders.
