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.
    • Create Export File with HTML Code: The JourFixe on 09 FEB 2026 decided to remove the setting "Export Essay Question with HTML code" from the Test & Assessment administration. Code was removed on 09 FEB 2026 from the release_10, release_11, and trunk branches. (ILIAS Version 10.6)
  • Mediacast:
  • Page Editor:
    • The owl carousel library has not been proposed for ILIAS 10 and thus is not part of it anymore (it was part of the legacy accordion UI element). The page component now implements a simple transisition between carousel pages.
  • Page Editor:
    • The legacy UI element advanced select input gui has been removed from the code. The editor now uses a standard select input in forms for these cases. These do not show advanced style visuals.
  • UI:

    The merge of https://github.com/ILIAS-eLearning/ILIAS/pull/11444 will cause the following breaking changes. Given the novelty status of the entity (and associated) UI component(s), such cases should be rare, and any breaking change could be fixed in a backwards compatible manner. We therefore consider these breaking changes acceptable, as their value outweighs their harm.

    • Breaking change for plugins that provide a custom implementation of `ILIAS\UI\Component\Listing\Entity\Factory` and/or `ILIAS\UI\Component\Listing\Factory` by using the according exchange mechanism.
    • Breaking change for plugins that provide a custom implementation of the following UI components and their respective interface:
      • `ILIAS\UI\Component\Entity\Entity`
      • `ILIAS\UI\Component\Listing\Property`
      • `ILIAS\UI\Component\Symbol\Glyph`
    • Breaking change for skins that replace one or more of the following templates:
      • `Entity/tpl.entity.html`
      • `Listing/tpl.propertylisting.html`
  • Course: In learning objectives-driven courses, the "Settings for the Learning Objectives-Driven Course" info blocks that sometimes accompany objects are removed in version 10.10 as a usability fix.
