Dear list members,
the Technical Board would like to announce that we decided to support PHP 7.4 for ILIAS 6.
As mentioned on the 'Required and Supported for ILIAS 6' page  we kept the option open to support the PHP 7.3 succesor with ILIAS 6. Since at least end of November 2019 we all know that PHP 7.4 is the latest PHP major release and successor of PHP 7.3. Because the popular operating systems (like Ubuntu 20.04 LTS) are shipped with PHP 7.4, we hereby would like to officially state that ILIAS 6 supports PHP 7.4, too. All of our unit tests are already successfully executed in a TravisCI PHP 7.4 build since last year.
We highly encourage all component maintainers to handle issues being filed for ILIAS 6/PHP 7.4.
Have a look at our installation documentation  for further information regarding supported software versions.
Best regards Michael Jansen
on behalf of the ILIAS e.V. and the Technical Board
