[XF Release] XenForo 2.2.15 Full NULL 2.2.15

XenForo 2.2.15 Released​

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!

Some of the changes in XF 2.2.15 include:

• Avoid setting duplicate List-Unsubscribe headers.
• Include first post QA schema items unconditionally.
• Make outdated PHP version notice in admin control panel clearer.
• Retain the original unsubscribeEmailAddress option for backwards compatibility.
• New unsubscribeEmailHandling option to replace the new unsubscribeEmail option and conclusively fix issues arising from yesterday's XF 2.2.14 release.
• Fix URL unfurls no longer unfurling.

Please note that XenForo 2.2 has higher system requirements than earlier versions.

The following are minimum requirements:

• PHP 7.0 or newer (PHP 8.2 recommended)
• MySQL 5.5 and newer (Also compatible with MariaDB/Percona etc.)
• All of the official add-ons require XenForo 2.2.
• Enhanced Search requires at least Elasticsearch 2.0.
