Can we also move this document elsewhere for the time being ?
If we were to release tomorrow, a new page would appear (Migrating from v1beta1) which would be a bit confusing as it would make it look like v1 is already available, when it is not yet the case.

@vdemeester Thanks for the comment. May I ask where would be a good place to put it or shall I just remove it at the moment ?

Hum we definitely shouldn't remove it. Maybe in a dev/docs or anywhere that is not "indexed" by our website.
