We’ll be moving to an upgraded environment for Project web 21:00 UTC today. This will upgrade various packages, though php will be staying on 5.3, so many web-apps shouldn’t need updating. Python for cgi scripts will be upgraded to 2.6 as the default, with 2.7 available (2.4 will no longer be supported).
If you have any issues after this is complete, please let us know: http://sourceforge.net/support
