This release fixes a bug in the back end where child records were potentially ignoring the setting doNotDeleteRecords. In addition, the section headings of content elements are now also displayed, which should improve the overview of nested elements. There was also work on performance - Contao should get a noticeable performance boost, especially for pages with a lot of data (content elements, front end modules).
