llvm dev - Jan 2021 - [Openmp-dev] RFC: Upcoming release schedules and creating a formal schedule for future releases

This sounds good to me (maybe spell out roughly what date 2.0.0-rc1
would be to make it easier to get an overview).

Thanks,
Hans

How about we specify the week, rather than the day?

If our aim is Tuesday, then it'll often be early in the week, so people
won't be waiting too long, but allows some flexibility if something bad
happens and avoids multiple emails on the list about "where's the
release?".
