You wrote ~11d on the 13th.  This upgrade is from the 2nd, ~11d before
the report.  Can you tell me whether this upgrade happend before or
after the boot that led you into the 11d uptime?  If it happened after
then yes, you were most likely running the older gpg-agent without
restarting it, which would explain the failures you saw.

fwiw, gpg should provide warning messages to stderr if it discovers it's
talking to an older agent, but if you only accessed it through enigmail
maybe those warning messages weren't propagated through to where you
could easily see them.
