The Neos Team postponed the release of Neos 9.0 until we are confident that most people will have a smooth upgrade path. One requirement is that enough projects we know of are using it in production. So, if your web agency‘s website is running on Neos, please start upgrading it and gives us feedback about any issues you might find.
The Neos Team has been working on a new content repository for the last 8 years. What took us long? The new CR is event-sourced, with sophisticated projections and a thoroughly designed PHP API, something which has not been done before, not even outside the PHP ecosystem.
Here are the slides for the talk @sebastian and me gave today at the International PHP Conference in Munich. Ping us, if you have any questions or feedback!
