Calendar adjustments
Currently the Alpha and Beta releases for the winter cycle end up a bit busy.
Alpha always ends up on the first week of January, which is occupied by either people traveling back or it's still Holidays for a lot of places like Easter/Orthodox European countries.
Likewise, Beta (which we already shifted a bit) used to coincided with FOSDEM, now it's the week after, but turns out everyone is still traveling back and rushing to merge things before the API freeze.
Proposal:
- Make Alpha always be at least 2nd week of January
- Make Beta be 2nd or 3rd week of February and hopefully not the week right after FOSDEM/conference circuit
