The Neos development collection is tagged with a new beta: Neos 9 Beta-9
The Neos.Ui and Flow will remain on Beta-8
The reason for this fast new beta is a critical bug in the ContentGraph projection which lead to events not being able to be replayed. Thanks Marcin Sągol for uncovering this bug.
Upgrade instructions from Beta 8
In your composer.json you should require 9.0.0-beta9 for all Neos packages from the development distribution.
"neos/neos": "9.0.0-beta9",
"neos/neos-ui": "9.0.0-beta8"
Breaking changes in Neos
