Unsurprisingly, Linus Torvalds has let
it be known that he will do a 6.7-rc8 release (rather than 6.7 final)
on December 31, thus avoiding opening the 6.8 merge window on New
Year’s Day.

Just FYI – my current plan is that -rc7 will happen this Saturday
(because I still follow the Finnish customs of Christmas _Eve_
being the important day, so Sunday I’ll be off), and then if
anything comes in that week – which it will do, even if networking
might be offline – I’ll do an rc8 the week after.

Then, unless anything odd happens, the final 6.7 release will be Jan
7th, and so the merge window for 6.8 will open Jan 8th.
