XenForo Released Upgrade

xF2 Release XenForo Released Upgrade 2.2.15

No permission to download
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  • Make outdated PHP version notice in admin control panel clearer.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.

Current requirements​

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.
XenForo 2.2.14 is now 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.

In addition to the usual slew of bug fixes and improvements, there are a few notable changes in this release.

Compatibility with PHP 8.1 and 8.2​

Most compatibility issues between PHP 8.1 and 8.2 have been addressed. Remaining issues might trigger E_DEPRECATED warnings in the xf_error_log during debug mode, but these are generally non-critical and can be disregarded.

Email unsubscribe changes​

Previously, we allowed users to unsubscribe from emails through certain mail clients when the automated unsubscribe handler was configured. With the introduction of XenForo 2.2.14, we're implementing a new standard feature that processes unsubscribe requests via HTTP. This feature is activated by default and requires no additional configuration. Your current settings for email unsubscribing will not be altered. The recent updates include:
  • Enhanced handling of the List-Unsubscribe header to support both mailto and HTTP methods.
  • Automatic inclusion of the unsubscribe header in a broader range of outgoing emails, such as notifications for watched threads and activity summaries.
  • A default-enabled option to send confirmation emails to users once their unsubscribe request is fulfilled.
