This is beta software. It is not officially supported. We do not recommend running it in production.
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.
Add-ons and custom styles may be broken after upgrading to 1.4. You must test your add-ons thoroughly or look for updates. Be especially careful with add-ons that cover similar features to ones that are added to 1.4; these may conflict with the core XenForo data. If data conflicts are found, they will need to be resolved in a new add-on release or by removing the add-on before upgrading to 1.4.
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. If in doubt, always do a test upgrade on a copy of your production data.
