If you would pick *three significant* highlights, what would it be?
Why? There is no release yet. Sounds like you want to prepare an announcement.
Yes, its not worth it? yaxim was publishing on their update, so I connected with that. Then I take it out
You could mention what is worked on. But then how do you decide when you tell about which project is doing what in their development branch right now. I'd generally just announce releases. In this case you can link Ge0rgs post and highlight the changes he mentions.
But I wouldn't go into prosody trunk too much, but that's just my opinion. :)
