Download OpenCms

  • OpenCms 17 gives content managers the new app "Date search" to find content that has been changed in a certain time range. The "Websites" app allows to easily export the content of a complete site for archiving. An option has been added to hide "sensitive" content in the Offline project. The default Mercury template has been further improved, e.g. with SEO optimized job postings, a "spacer" function and marker clusters for maps. OpenCms 17 has also been tested and certified using Java 17 LTS and 21 LTS.
