Important Changes

  • New Component and Directory Structure
    As part of the implementation of the new component and directory structure in ILIAS 10, the overall file layout has changed significantly. Please note that the webroot is now located in ./public, and this requires an adjustment in your web server configuration.
  • Manage System Styles Removed
    With ILIAS 10, the management of system styles has been discontinued for security reasons. Styles can no longer be edited via the Administration area. For more details, see: https://docu.ilias.de/go/wiki/wpage_8390_1357
  • Support of Subtitles
    SRT subtitle support was changed to VTT subtitle support

Changed Behaviour

  • Data Collection:
    • The new field type "Copy" was added to the data collection and can now be selected for new fields! A copy field shows a selection of values from another tables entry and copies those to its own value without a reference, making it robust against manipulation and deletion of the origin value.
  • Media objects:
    • We moved to native video tags which do not officially support srt files for subtitles. The supported standard is WebVTT. ILIAS tries to convert srt to vtt on the fly. You will be not able to upoad srt files anymore, please use vtt files instead, see https://mantis.ilias.de/view.php?id=43935
  • Object:
    • Titles and Desciptions will always be interpreted as strings. Contained html-tags are encoded and shown in their literal form.
  • Test & Assessment:
    • Cloze questions do not offer the option to edit gaps in modals anymore. All gaps are available, as previously, underneath the cloze-text input field.
    • Redirect: Starting with Version 10.3, we introduce a separate option to redirect to the logout screen, as redirecting to https://instance.url/logout.php does not work anymore since ILIAS 10.1.
  • Mediacast:

Updated Languages
