OpenCms 12.0

OpenCms 12.0 is now available for download.

OpenCms 12 features a headless JSON API for REST content access, together with several JavaScript demo applications that show how to use it. The default "Mercury" template has been greatly improved. Template variants allow to completely switch the generated HTML of a website simply by configuration. The updated WebDAV implementation enables mounting the OpenCms virtual file system from any WebDAV client.
