I don't see any of the versions before v5, you should restart numbering
when you post something to the list for the first time.

Regardless, the merge window has now started (after Linus tagged 6.0)
and will last until he tags 6.1-rc1 (two weeks from now). During this
time we'll not be taking any patches adding new features/support so
please repost in around 2 weeks.

Thanks!
