@emtwo This is already not happening in the current dev version, so I suggest to finish the rebase cycle and deploy m30 as soon as possible. Do you know what's missing other than Q&A?

[emtwo]

Nothing is missing other than QA and potentially an email to users in advance with a heads up on UI changes.

@emtwo Excellent, I asked Alex to start the Q&A process on dev and he said he'd get back to us until the end of the week.
