OpenCms 18 release notes

OpenCms 18 adds a new "Place element" mode in the page editor that allows precise placement of elements as an alternative to drag & drop. Reused content is now clearly marked to prevent users from accidentally changing content that is used on multiple pages. Automatic typographical correction of quotation marks has been added to all of the editors. "Dead links" in content that is entered in a WYSIWYG editor are now automatically disabled. The Jetty 12 servlet container is now supported as an alternative to Tomcat. Our Mercury template includes several new features, such as setting different image formats for mobile and desktop, opening hours for places, and internal search result boosting for defined keywords.
