5.1.5 (stable)

Release 5.1.5 has been published on April 15, 2016
  • Please read the ILIAS 5.1 feature page for information about new and abandoned features and changed behaviour of this version.
  • Information about first time installation can be found here.
  • Securing web files has been changed in 5.1 due to the new Web Access Checker. Please read how to put HTML and SCORM modules, media files and user profile images under RBAC control.
  • With ILIAS 5.1.5 the "Return-Path" used for external emails is configurable (for PHP > 5.3.x or deactivated 'safe_mode') from within the ILIAS mail administration. Certain server configurations which rely on the "Return-Path" being set automatically on OS level require this new configuration to be properly set in ILIAS. To address this as a hotfix, a new configuration option, located at "Administration » Mail", was introduced. Please check this option because due to obvious reasons, there is no meaningful default that works for all platforms. This step was necessary due to the introduction of PHPMailer, which was necessary due to the introduction of HTML brackets. PHPMailer sets the "Return-Path" property to the "FROM" property per default, so we had to make this changeable (affects -f mail()-parameter and ini setting: 'sendmail_from').
Instructions for updating ILIAS can be found in section 3 of the general installation instructions. For major updates (e.g. 4.4.x -> 5.0.x) the safest proceeding is, to upgrade a copy of your productive system first and test whether everything works ok.
If you use a customized skin/style, please change the skin settings for root user and default of installation to ‘delos‘ before upgrading from a 4.x version to 5.1.x. Otherwise you may not login any more due to templates changes in 5.0 and 5.1.
