Required and Supported Software ILIAS 8

1 Required Software Versions

The following software versions are required/supported for ILIAS Release 8.

1.1 PHP

• ILIAS 8 will support PHP 7.4 and 8.0.
• ILIAS 8 will not support PHP 8.1. Reasons are:
  • It is not possible to support the range of PHP 7.4 - 8.1 in a single release without suppressing E_DEPRECATED errors for 8.1, and we don't want to soften our error reporting policy for future releases of ILIAS.
  • We can't guarantee all our dependencies are compatible with PHP 8.1 until the beta release.
  • Nevertheless, all component maintainers and contributors MUST provide commits with passing unit tests for the PHP 8.1 build.
  • If you have any questions, do not hesitate to contact the Technical Board.
• Support for PHP 7.3 will be dropped! Reported PHP bugs aren't fixed anymore by the PHP project. Security issues have only been fixed until fall 2021: https://php.net/supported-versions.php
• OS Support: http://phpversions.info/operating-systems/
