The following public templates have had changes:
Note: add-ons, customizations and styles made for XenForo 1.x are not compatible with XenForo 2.x. If your site relies upon these for essential functionality, ensure that a XenForo 2 version exists before you start to upgrade. We strongly recommend you make a backup before attempting an upgrade.
Installation and Upgrade Instructions for XenForo 2.1
Full details of how to install and upgrade XenForo can be found in the XenForo 2 Manual.
If you are already running XF 2.1 or above we strongly recommend upgrading directly from within your control panel.
Note that when upgrading from XenForo 1.x, all add-ons will be disabled and style customizations will not be maintained. New versions of add-ons will need to be installed and customizations will need to be redone. We strongly recommended that you make a backup before attempting an upgrade. Once upgraded, you will not be able to downgrade without restoring from a backup.
