We found an issue with beta4 that we didn’t want to keep for longer so we directly released beta5.
All that was said in the beta4 topic is still pretty much valid.
To install use:
composer create-project typo3/neos-base-distribution neos-2.0.0b5 2.0.0-beta5
The very unspectacular release notes can be found at
Nothing to watch for, really minor chnage between beta4 and beta5.
