I'd like to call it 2.12BSD but I'm not sure I have the imprimateur
for that. Besides which it's a lot of work to go thru the source
tree and change all the references ;)
Indeed it has been a while since the 20th anniversary (1990, or was it
1991?). Since the initial release of 2.11 in '91 or '92 there've been
a "few" changes/updates made.
The current /VERSION file is attached below. While it's not NetBSD
or Vax related it does seem to fit in with the current discussion.
Happy reading.

2.11 BSD
============
NOTE --
This would have been the third release of 2.10BSD; but since
the filesystem has changed and a coldstart is required
this release was instead called: 2.11BSD
Work on this release has been on going since the initial
release of 2.10.1BSD in January 1989. This release,
is in celebration of the 20th anniversary of the PDP-11.
This release incorporates all fixes and changes posted
to the group comp.bugs.2bsd on the newsnet since 2.10.1BSD
was released.
Present in this release are several more missing pieces
from the 4.3BSD distribution:
1) the kernel logger (/dev/klog)
2) the namei cache
3) readv(2)/writev(2) as system calls rather than
emulation/compatibility routines
4) the shadow password implementation released for 4.3BSD
5) a TMSCP (TK50/TU81) driver with standalone support
(bootblock and standalone driver)
6) a couple more network drivers have ported or made to
work: if_vv and if_acc
7) the portable ascii archive file format (ar(1), ar(5)) has
been implemented.
8) last, but most importantly, long filenames!
This last is the reason a coldstart kit is necessary. The
on-disc directory structure has been ported from 4.3BSD
(along with the utilities that know about on-disc
directories via the raw filesystem: fsck, ncheck, icheck,
dcheck, etc.) and is not compatible with previous versions
of UNIX for the PDP-11. A limited amount of backward
compatibility is present in a version of dump(8) which
can read old filesystems. restor(8) automagically converts
old dump tapes to the new format on input.
MAXNAMLEN is now 63 instead of 14. It is possible the
limit could be higher, but with MAXPATHLEN at 256 a
MAXNAMLEN of 63 was judged sufficient.
MANY other fixes and changes have also been made, see the
"Changes To The System" document which describes the changes
made to both the kernel and the application programs.

Below is the original VERSION file distributed with 2.10.1BSD
-----------------------------------------------------------------------
NOTE --
This is the second release of 2.10BSD; most of the changes
are part of the addition of supervisor space networking in
the kernel, although there are other changes.
To give some idea of the dates involved, distribution of
2.10BSD by the USENIX Assoc. started in fall of 1987.
Distribution of this source started in January of 1989.
