History

Development of Concrete CMS began in 2003 as a rapid-design approach to building the now-defunct LewisAndClark200.org, the official site for the Ad Council's National Council for the Lewis & Clark Bicentennial. The version 7 release of concrete was incompatible with prior versions. All prior versions became known as the legacy branch, with the final version being 5.6.4.0 before reaching end of life status on 24 August 2019. Modern Concrete (version 7 and above) features a new user interface, a user-accessible data model called Express, an extensive permissions model, and in-context WYSIWYG editing. Version 9 was released in October 2021. This major new release added new features like multisite support, boards, new built-in gallery block and a new UI based on Bootstrap 5. Regular updates and security patches have been released.
