XenForo is fast and convenient system management forum. The developers of this software product dedicated many years working on such a hit as VBulletin. Therefore, among the priorities: high speed, resistance to heavy loads, as well as advanced functionality.
We are pleased to release XenForo 2.0.1, the first maintenance release in the XenForo 2.0 series. This release primarily targets bug fixes and other small improvements. We recommend all customers running XenForo 2.0 upgrade to this release to benefit from increased stability.

Note: add-ons and customizations made for XenForo 1.x will not be compatible with XenForo 2. If your site relies upon add-ons for essential functionality, ensure that a XenForo 2 version of the add-on is available before you start to upgrade. Style customizations will need to be redone and will not be maintained after the upgrade. We strongly recommend you make a backup before attempting an upgrade.
