For me the long stretch of "B'' 's is a little confusing at times, but repetition helps
Buster is the new Stable Debian 10
Bullseye is the new Testing which will be Debian 11 in approx 2 years (that can always change)
Bookworm will be the next name for Debian 12, but it is not the name of what comes down to testing.
As always Sid is the name of where packages come to Testing. Sid is that mean kid who breaks toys.
peace out.
