This release is the last Contao 4.9 release with active support! Contao 4.9 is now in "security only" support mode and will no longer receive regular bug fixes! For another year, only security vulnerabilities will be fixed.
As of this release, invalid entries for month or day in the URLs of the calendar module lead to 404 pages and the breadcrumb front end module has been equipped with WAI-ARIA tags (check your adjusted templates!). It also fixes a bug that could cause members to be deleted from the database under certain circumstances. An update is therefore strongly recommended.
