Been busy as heck around here at Rdio, Inc still loving chef but can not wait for 8.0
Some features I am looking forward to:
Knife: a command-line utility used to interact with a Chef server directly through the RESTful API.
one of the best parts of this that I have seen is that it will make multiple admins much easier to deal with. My favorite command so far: cookbook upload
Openid no longer only option for logins: Infact the whole login stuff has changed and with knife there will be even less reason then ever to login to the UI, this is a major change as the whole auth stuff is in flux right now.
Better Serach: now this one I have not played with much but they say it will be much better based partially on the databag addition
Databags: Data bags are arbitrary stores of JSON data on the server that get indexed for search.
This will help you store data that is used across recipes with less effort.
I am sure there are more, but those are the ones I have played with so far. Its starting to feel like 8.0 will never ship and I just dont feel its ready to run in production just yet based on the lack of documentation but I have tasted enough to know I want it.
