This release improves the work with background tasks in particular: On the one hand, fewer database connections should be necessary from now on and on the other hand, the interaction of contao:cron and the maintenance mode has been improved. In addition, the insertion of images as <img src="data:image/png;base64,..."> in tinyMCE is now prohibited by default (previously possible via drag n' drop or copy and paste). In addition, the handling of CSRF tokens has been improved.

- #8232 Make the maintenance tasks in the user profile configurable (Toflar)
- #8211 Skip cron jobs in maintenance mode (aschempp)
