Yes! If you were not at the plenary, you did not dream: alpha06 was a local release… but now everyone is at the same level with alpha07!

I hope you will forgive us, but we have taken your feedback on attribute naming to the heart, so we called it a full new version number! This is likely to be the last breaking change. Not as large scale as last time, but you should see some complaining from your favourite CCE. We think it is for a good cause.
There are a lot of small and large bug fixes in there too. Only 2 objects are now missing, and they are both very near completion, so you should get an update in the next weeks.
I hope you enjoy.
