With the first round of bug fixes complete, we are now ready to release the second beta version of XenForo 1.1.0. This new version resolves several commonly-reported bugs, such as minor incompatibilities with PHP 5.2, problems with assigning thread prefixes to forums and defining default prefixes, upgrade errors, errors in HTML email and a variety of others that you can review in the Resolved Bugs Reports forum. We recommend that all customers running Beta 1 now upgrade to Beta 2. All licensed customers may now download the new version from the customer area. This is Beta Software Please remember that this is beta software. It contains known bugs and incomplete functionality. We do not recommend running beta software in a production environment, and support is limited at this time to questions here on the community forums. If you choose to run beta software, it is your responsibility to ensure that you make a backup of your data. We recommend you do this before attempting an upgrade. Installation and Upgrade Instructions Full details for how to install and upgrade XenForo can be found in the XenForo Manual.
