As always, this release contains all the improvements of the latest version 4.13.45. Accordingly, this bugfix release may fix existing problems with CSRF handling when sending forms. In addition, the duplicate sending of forms is now prevented by default and improvements have been made to JavaScript handling in conjunction with the sending of forms via Ajax. Both changes affect the form_wrapper.html5 template. If this has been adjusted in your installation, the corresponding changes must be applied. In addition, the entire (!) implementation of the background workers has been adapted to address various bug fixes. In principle, there should be no need for developers to take action, but it is recommended to keep an eye on the queues. The documentation has already been updated.
