Can I distract people for a moment to ask a couple procedural questions about this change? I maintain my own fork of https://github.com/python/cpython, but don't yet see a main branch on python/cpython.

When is the new main branch supposed to appear
Once it does, what will I need to do other than to update my fork?
I have a branch in my fork (register2) which is a branch from my fork's master. Not being a Git whiz, how will I switch so my register2 branch has the new main as its upstream (I think that's the correct word)?
How long will master be around after the switch before going to that big branch in the sky?

I was able to scrounge up the few commands necessary to make the change to one of my standalone projects and successfully move it from master to main. The several articles I at least peeked at all followed pretty much the same recipe as this one:

https://stevenmortimer.com/5-steps-to-change-github-default-branch-from-master-to-main/

None, however, discuss how the change will affect forks. I'm a bit unclear how that part is supposed to work. I thought I might find a process PEP about this change, but saw nothing obvious in PEP 0. I'm sure this is a trivial few git commands for those more familiar with the toolchain than I am, but I see over 18k forks of the repository. I suspect a few people out of that crowd will be in the same boat as me.

Thx,
