Merge moved to Thursday 29th

Hello,

Because we want to synchronize the release of 42 and 44 devedition (next
Tuesday),
we are planning to perform the merge tomorrow, Thursday.
As a consequence, nightly = 45, aurora = 44 and beta = 43 (42 is already
in release).
This will give us enough time to validate the first aurora build.

I apologize for the very late notice. Of course, we will be friendly
with uplift requests.
