XBMC 13.1 released and PPA installation instructions included
Backup your data Before upgrading we would recommend you create a backup of your current userdata folder which contains all your current settings and database files. In the unlikely case that something went wrong during your upgrade, a backup will ensure that you are still able to go back to the previous state. Where the userdata folder is located on your system can be found on our userdata wiki page. Do note that when first upgrading from Frodo 12.x it may take some time until you see the familiar homescreen as several internal upgrades need to be performed.
Add-ons As mentioned in previous blog posts, due to changes related to our add-on system and skin improvement, certain plugins, scripts and skins may become incompatible when upgrading from Frodo to Gotham. Sadly this is part of the continuing process of development and improvement. We hope the impact of these changes will be limited but we feel a warning would be beneficial. If there are any addons you particularly depend on, we advise that you visit the forum thread of that add-on to see if the author has ensured support in XBMC 13.
After you have updated from Frodo or any earlier alpha or beta it may be beneficial to force refresh the XBMC.org repository. This will ensure the most recent repository list is loaded and needed updates become available
