Yes, we recently did 3.9.2 release, because the move to 4.x (which is
the first version w/o ZK) is a somewhat larger step for some users.
At this point, it's unclear if there will be 3.9.3 release or not. But
as more time progresses, and we get new releases 4.3, 4.4 out, the
probability for a 3.9.3 release decreases.
I would highly encourage users to make the step off 3.x and onto 4.x.

Do we have any thoughts on whether there will be a 3.9.3?

In general, we maintain 3 versions, so with AK 4.2 release, 3.9.x would
actually hit EOL.
Given that 4.0 is a major change with ZK removal in favor of KRaft, it
will most likely be maintained a little longer though. We are currently
discussing a 3.9.2 bug-fix release.
But it will depend on overall community demand, if their will be a 3.9.3
bug-fix release or not. In general, I would not expect 3.9.x to be
maintained too much longer, and migrating off ZK, and to upgrade to 4.x
is highly recommended.
