Contao Open Source CMS 5.3.8

Contao 5.3.8, a new version of the Contao open source CMS, has been released.

This release fixes various errors that affect the operation of Contao. An update is therefore strongly recommended. Among other things, the incorrect start of background workers has been fixed, which should now run normally again. In addition, a concept problem with the permissions has been adjusted so that the duplication of content including its child elements now also works again. Furthermore, various errors during the migration from Contao 4.13 to Contao 5.3 have been fixed and the undo function has been improved. Twig has also received some adjustments, so there is now a deserialize filter and it is now allowed to use hyphens in Twig template file names everywhere again.
