This is an early evaluation release of 4.1.11. While QA has tested most of the fixed issues in this release, additional code changes are in progress, and functional regression testing has not yet been completed. As such, vBulletin 4.1.11 ALPHA 1 should not be used to upgrade your live sites.
What's New in vBulletin 4.1.11 Alpha 1?
The largest change in 4.1.11 Alpha 1 is the conversion of the vBulletin Mobile Style to a master style, including changes to the mobile style install/upgrade script. Once 4.1.11 is released, customizations to the mobile style for your sites will not longer be overwritten on upgrade.
