Release 4.1.0 RC 2 has been published on 27th August 2010.

THIS IS JUST A RELEASE CANDIDATE AND NOT A STABLE RELEASE.
YOU MAY ALREADY USE IT IN PRODUCTIVE SYSTEMS, BUT PLEASE TEST ALL FUNCTIONALITIES THAT ARE IMPORTANT FOR YOU BEFORE USING IT AND PLEASE BACKUP YOUR SYSTEM. ALSO CHECK OUR MANTIS BUGTRACKER FOR OPEN ISSUES.

Please read the ILIAS 4.1 features report for information about major changes and new features of this version.

Information about first time installation can be found here.

Before upgrading an ILIAS installation to 4.0 you will need to upgrade to 3.10 first. Instructions for updating ILIAS can be found in section 3 of the general installation instructions. For major updates (e.g. 3.10.x -> 4.0.x) the safest proceeding is, to upgrade a copy of your productive system first and test whether everything works ok.
