It's the base level designation.
Thanks, Paul. So did the base level releases come before the real
release, as in something like alpha test, beta test, field test, etc? That
would that mean that "10.1" (no letter) is a later release than
"10.1L"?
Or was it the other way around - the base levels were issued after the
main release ? In that case 10.1L is later than 10.1?
No, the base levels were during the development cycle. So the first internal checkpoint
would have bee 10.1A, beta might have been 10.1G or something like that, and production
release a few baselevels later so L. The release would get whatever base level
designation applied to the final baselevel of the release cycle.
There was also a DEC convention, I don't remember if RSTS used it but I know RT11 did
it at least at one time, which is to use the V prefix for production releases, X for
internal development baselevels, and Y for beta. I have tucked away a copy of RT11
Y02-20, so a beta snapshot of the V2 release.

The RSX family also used base level for describing both internal and external releases
although the actual naming conventions differed between the various products:
RSX-11M-PLUS V4.6 BL87 2044.KW System:"RSXMPL"
1920K (word) IAS Version 3.4A Baselevel 3414
