I am very happy to announce that Concrete CMS 9.0 is now available!
After years of development and several months of release candidates, 9.0.0 is here! There’s way too much in this release for me to summarize here; for that, you should check out the blog post above.
Thanks to everyone who helped throughout this process with code and bug reports, especially those who were active in the forums and GitHub throughout the release candidate process. We’ve squashed a lot of those early release candidate bugs, and have really improved backward compatibility with Elemental and other themes that aren’t built off of the latest Concrete technologies. I’m happy to report in my testing that themes customized with Elemental work 100% with the new customizer (without sacrificing all the excellent progress of the new, skin-based theme customizer.)
It’s not going to be a perfect process – and for the moment we’ve disabled the automatic process of making add-ons available for version 9. Developers who verify their add-ons work with version 9 should login to their marketplace administrative area and update their compatibility. This should get your add-ons and themes officially serving to version 9.
