Core Releases

We are very excited to that Concrete CMS 9.1.0 is now available! 9.1.0 features many improvements, new features and bug fixes, including:

  • Much improved compatibility with PHP 8 and PHP 8.1.
  • Improved appearance and functionality when editing block, area, layout and container styles inline in the page
  • Express improvements like the ability to mark attributes as unique, handle re-use across objects, and much more.
  • Much improved version comparison feature that can compare the HTML of two page versions and highlight differences
  • Improvements to Dashboard listing screens and the file details screen

Additionally, there are many behavioral improvements, performance improvements, and bug fixes included. The full list is far too large for this blog post. Click here to read all about what's new in version 9.1.0.

9.1.0 has been tested extensively during this release candidate period. It should be a stable upgrade for all sites running 9.0, 9.0.1 or 9.0.2, and it's definitely ready for testing against your 8.5.x sites. If you're running PHP 8 or interested in running it, 9.1.0 is fairly mandatory – the list of PHP 8 fixes is extremely long. Please check it out and let us know what you think!

We've just released two maintenance versions of Concrete CMS – version 9.0.1 for those of you running version 9, and 8.5.7 for those on version 8. They both offer behavioral improvements, bug fixes and security fixes, and are highly recommended.


It’s been a long time coming, but we’re very pleased to announce that Concrete CMS version 9 is now available. In development for over three years, Concrete 9 overhauls numerous aspects of the interface, adds new tools for content editors like Containers and Boards, offers a completely rebuilt and reworked file manager, upgrades many third partyJavaScript and PHP libraries shipped with the core, and comes with a new default theme for the first time in seven years.


We're happy to report that Concrete CMS 8.5.6 is now available. Concrete 8.5.6 offers a number of bug fixes, improvements and security updates, and also fixes issues connecting to the Concrete CMS marketplace. It is highly recommended for those of you running Concrete 8.5.

That was fast! We got a lot of great feedback on our first Concrete 9.0 release candidate, and noticed a fair number of real issues. In order to best keep this process moving, we thought it'd be best to fast-track our second release candidate. Here it is!


The first release candidate for Concrete CMS 9.0 is now available! This release has been in development for several years, and is our biggest release to date. Read on for more information about what's changed and what you can help with. 


concrete5 8.5.5 Release Candidate 1 is now available! We'd like help testing this one, since we'd really love for it to be the last release before version 9! This version of concrete5 fixes some bugs, issues with the theme customizer, some JavaScript console errors, and a bit more.

concrete5 8.5.4 is now available! Sometimes when we do a big release, we have to do another one pretty quickly. This is no exception. 

8.5.3 accidentally shipped some new features that aren't quite ready yet. 8.5.4 turns those off, but also makes available a ton of new features that we've had in our development pipeline, including Express search indexing improvements, the ability to export Express objects from the command line, a new custom attribute type of User Group, the ability to set file storage locations at the folder level, and much more.
