If there’s not already such a list - create a recipient list for press contacts including t3n, php magazine and the likes would be good I think and send them the news.
Another thing that should be updated before the release: https://www.facebook.com/typo3neos
If there’s a new Neos Facebook page it should be merged with this one.
I’ve just checked it - both facebook.com/neos and facebook.com/neoscms are available.
I think one of them should be registered and merged with the typo3neos page.
