Ok, now that I understand that the 1.4 is not intended for monthly snapshots, let me rephrase the question:
Can I upgrade my 1.4-rolling-202101171022 to a 1.3 monthly snapshot?
If yes, can I use the current 1.3-rolling-202101 snapshot or do I have to wait for the 1.3-rolling-202102 snapshot? (I don’t know if that snapshot was released before or after the nightly I’m running on)
If I do have to wait for the 202102 one, when will it be released? (Not knowing when the January snapshot was released, I cannot predict when the February one will be released)
