As always, this release contains all the improvements of the latest 4.13.38. In addition, some performance improvements have been made, especially large page trees and database dumps should be noticeably faster. In addition, the Twig integration has been improved - this applies in particular to the changed order of attrs() calls, so that it is easier to adapt templates of the core to your own needs. To increase backwards compatibility with the "Personal Data" module, there is a new checkbox to optionally enforce full authentication and bugs in the CSP integration and database migrations have been fixed.
