Xenforo - A compelling community experience.
Intuitive. Social. Engaging. Fast. XenForo brings a fresh outlook to forum software.

• Social Engagement
  Keep your users coming back by letting them earn trophies for reaching milestones. An intuitive "like" system makes users feel appreciated for their contributions, while integration with Facebook allows easy registration and sharing.
• Recent Activity Stream
  Allow people to easily see all the recent happenings on your forum, beyond just the messages posted. Members can follow each other to get their own personalized news feed showing the content they want to see.
• Alerts
  Make it easy for users to stay up to date with updates that are applicable to them. They'll receive alerts when someone quotes their post or responds to a status update, when they receive a new trophy, and more.
• Easy Styling
  You can use XenForo's simple color changer to easily change the look to suit your needs. You can make further changes through an extensive style property editor, or edit HTML and CSS in your favorite editor. No code changes necessary!
• Great Add-ons
  XenForo is built to be the most extensible and flexible community software ever. Check out the huge array of add-ons already available in the resource manager, or get help writing your own add-ons with the XenForo framework.
• SEO Built-in
  With XenForo there is no need to pay more for your search engine optimization needs. Human-readable URLs, semantic HTML with embedded microdata, and many more SEO features are present in the very core of the system.

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.

Minor security fix
In previous versions, add-on or style archives could escape their container directory and bypass subsequent validation checks. Exploiting this requires an administrator with the pertinent permissions to upload a maliciously-crafted archive. This has been addressed in XenForo 2.2.14.

Update on XenForo 2.3 and XenForo 3.0
Work continues towards the next versions of XenForo. @Kier is now working full time on some exciting stuff for XenForo 3.0 while the rest of us are working towards getting XenForo 2.3 stable enough for a public beta release, in addition to the last few bells and whistles for both the core software and some enhancements to our official add-ons. Additionally, we plan to release one last update for XenForo 2.2, namely XenForo 2.2.15, which will incorporate significant fixes before we transition to primarily supporting 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.

Where necessary, the merge system within the "outdated templates" page should be used to integrate these changes.

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.

How to install / upgrade XenForo:
Copy all files in the uploads folder of the new version, overwriting the old files on your system. Run domain.com/install to install or upgrade.
The full version can be used for a new installation or an upgrade.
