Neos 9.0 released

Neos 9 comes with the biggest technical overhaul since we reworked the editing UI in React: the Event Sourced Content Repository. The Content Repository is the heart of Neos, it stores all your content, its properties, its relations, all your dimensions and now also a complete history of the changes that were made to it. 

We have worked on the concepts that are now the Event Sourced Content Repository since 2016. We reviewed, reworked and refined them again and again, building on what we learned from projects large and small. 

The Neos and Flow 9.0 release is not the finish line. It is the kickoff for the next decade of content management in Neos. Our vision for features that are a technical possibility now include comprehensive undo for editors, a content repository for assets, performance improvements and even ideas about true collaborative editing in Neos.

As with every X.0 release of Neos and Flow there will be rough edges that we will continually improve. We provide recommendations for how to start using Neos 9 and updating your existing projects in this article. We encourage all developers to start getting to know the new concepts and features in Neos 9 by reading the documentation and starting new projects with Neos 9 now.
