XenForo 2.0 is a major update from version 1. It includes a many new features and significant changes under the hood, with the core code having been completely redesigned.
Some of the new features include:
- Navigation management
- Emoji support
- Retina avatar and smilie support
- Custom thread fields
- Customizable member stats
- Generic payment framework
- The "what's new" system
- Extended media embedding features
- Quick thread creation
Note: add-ons and customizations made for XenForo 1.x will not be compatible with XenForo 2. If your site relies upon add-ons for essential functionality, ensure that a XenForo 2 version of the add-on is available before you start to upgrade. Style customizations will need to be redone and will not be maintained after the upgrade. We strongly recommend you make a backup before attempting an upgrade.
Please note that XenForo 2.0 has higher system requirements than XenForo 1.x. We will be updating the requirements test script in the near future to reflect this. The following are minimum requirements:
- PHP 5.4 or newer
- MySQL 5.5 and newer
