As always, this release contains the changes from the latest 4.13.39. In addition, the monitoring of background workers has been improved, where we can now also enjoy Windows support. Furthermore, a problem with the new permissions for front end modules has been fixed and various minor improvements have been made to the Twig templates. In addition, the clipboard is now correctly redirecting back to the list view and the built-in debug tools for developers have been improved, including the correct listing of voters in the Symfony profiler.
Why is there a bugfix release published shortly before a security vulnerability is closed?
When Contao 4.9.6 was released, we did not have this separation yet. There were problems with the update via the Contao Manager as well as bugs that had to be fixed the next day in a new version 4.9.7. Therefore, the core team decided not to mix security and bugfix versions anymore. Security releases will henceforth contain only the changes necessary to close the vulnerabilities.
