Important Changes

System Styles: Custom system styles from 8 and earlier do no longer work
- With ILIAS 9 the SCSS has been restructered according to the ITCSS structure suggested in the SASS guidelines. In addition, the depencency to less from Bootstrap has mostly been removed. However, the change from less to SCSS and the abandonment from Bootstrap means, that System Styles from 8 and lower are NOT compatible with ILIAS 9. They cannot be imported, be used, or compiled.
- However, note, that most of the css should still work. Also less and scss are not that far appart. Best read through our SCSS Coding Guidelines to get started.
JavaScript Dependencies: Removal of 'node_modules' folder from Git repository
- The 'npm' dependencies and thus the 'node_modules' folder in the ILIAS root directory were removed from the ILIAS codebase.
- All 'npm' dependencies will still be automatically added to the release builds (linked on the official ILIAS release pages) on GitHub.
- With this change 'npm' will become a requirement for ILIAS installations based on Git branches/tags. To install the 'npm' dependencies on such installations, you'll have to execute:
  
  npm clean-install --omit=dev --ignore-scripts
- The --omit=dev flag can be ignored for development installations.
Chat Server: Removal of 'node_modules' folder from Git repository
- The 'npm' dependencies and thus the 'node_modules' folder of 'Modules/Chatroom/chat' were removed from the ILIAS codebase in Git with the integration of PR 5128.
- All 'npm' dependencies will still be automatically added to the release builds (linked on the official ILIAS release pages) on GitHub.
- With this change 'npm' will become a requirement for ILIAS installations based on Git branches/tags. To install the 'npm' dependencies on such installations, you'll have to execute:
  
  npm clean-install --omit=dev --ignore-scripts
  
  The --omit=dev flag can be ignored for development installations.
Cron Jobs:
- With ILIAS ≧ 9.x and the application of PR 5720 the password must be omitted when executing the ILIAS cron CLI script, see also Installation and Maintenance: Cron Jobs.
PDF Generation:
- wkhtmltopdf has been removed from the code base.
Authentication/SAML:
- Due to an major release upgrade of the underlying 3rd party library, existing configuration files for SimpleSAMLphp have to be adopted according to the documention.
  - See: https://github.com/ILIAS-eLearning/ILIAS/tree/release_9/Services/Saml#config-changes-in-ilias-9 / https://simplesamlphp.org/docs/stable/simplesamlphp-upgrade-notes-2.0.html
- Furthermore, existing federations between ILIAS and SAML IPDs have to re-established due to necessary changes in the metadata XML file.
- When installing the composer dependencies on an existing installation, it might occur that you receive an error caused by the simplesamlphp/simplesamlphp library. In this case, simply remove the vendor folder once by executing: rm -rf ./libs/composer/vendor . Afterwards, install the composer dependencies as usual.
