Don't want to stray too off-topic but ...
release is coming soon, and other projects are in active development, like
an FPGA implementation of the DN6678 (and eventually the DPS8/M CPU). A lot
of the work is going into developer tooling for those projects, which isn't
that interesting to the "general public", but the community is very busy.
The guys working on it just spend more time hacking that posting updates
Since you mentioned GCOS, you should know that a lot of effort was recently
spent to get the GCOS environment up and working. Note this is GCOS being
emulated in Multics, not GCOS on the metal (yet - we need tapes). A better
write-up is actually in progress, but for now you can check the Wiki page:
https://multics-wiki.swenson.org/index.php/GCOS
(And yes, the simulator was originally a fork of SIMH to start, but at
this point it's barely related and future versions will have even less
SIMH code. This isn't to knock that project at all, just that DPS8M
simulator development has moved in a different direction.)
As the Flag Day, the only reference that I know to it is the one on the
multicians.org website. I could ask on the multicians list, or send an
inquiry to Tom Van Vleck.

There are still a few Multics sites running - and semi-active community development.
Courtesy of an old fork of SIMH that became a very full fledged DPS8/6800 simulator. I was running MR11 something on a Pi for a while, and then in GCP.
Brought back old times - my second computer - after GCOS.
*sigh*
I think there may also be a reference to Flag Day in the original printed Hacker's Dictionary, and I think in the Jargon file from which it was derived? I don't have any old copies of either around to check
