What happened to 8.3?
TLDR; 8.3 "Sleepy" was half-made when the editors changed. By the time the new editor was on-boarded, it was close enough to the 2021 update that they just rolled 2020 and 2021 into one update, calling it 8.4 to avoid internal confusion with the unreleased, half-made 8.3.
Why are there two 8.1 releases?
Spooky only included minor errata and clarifications, so the "Spooky" tag was enough to differentiate it.
