There are a handful of other bug fixes included, and we recommend that all customers upgrade to this new version, which contains minimal template changes and should be a painless update.
All licensed customers may now download XenForo 1.0.4 from the customer area.
This release of XenForo 1.0.4 follows our principle that third-point (x.x.X) releases should always be more stable than the preceding version, so for the most part you will not find new features in 1.0.4. Major new features will be reserved for second point versions (x.X.x).
Installation and Upgrade Instructions
Full details for how to install and upgrade XenForo can be found in the XenForo Manual.
