Contao 5.3.13, a new version of the Contao open source CMS, has been released.

As always, this release contains the improvements of the latest 4.13.47. In addition, the WebWorker has been improved again and the permissions for the content elements are now checked via the security voter. This is a pretty big change that should fix various bugs. Moreover, an edge case when duplicating with children has been fixed. Under certain circumstances, this caused data records to be copied endlessly.
