Hot on the heels of yesterday's XF 2.2.14 release and subsequent patches, we are today making XenForo 2.2.15 available for all licensed customers to download. We strongly recommend that all customers running previous versions of XenForo 2.2 upgrade to this release to benefit from increased stability, particularly if you already upgraded to XenForo 2.2.14.
As of this point, XenForo 2.2.14 and its patches are no longer available for download. We are still planning a final XF 2.2 release at some point around the release of XenForo 2.3!
