There are easy upgrade paths to the latest version. :) If you don't have mods/themes, you can go 2.0.8 -> 2.1.5 (or 2.0.19 if you want to stay on 2.0) with just one package! To 2.0.19 with mods/themes can be done in ~15 mins by applying updates one by one in the admin panel. Always backup first.

Simple Machines is proud to announce the release of SMF 2.1.5!

This update contains improvements, bugfixes and security patches. For all changes and info on how to update your SMF installation, please see: www.simplemachines.org/community/in...

Thank you and we hope that you enjoy the update! :)
