Are cygwin packages being pushed to mirrors still compatible with
cygwin-2.11.2, now that cygwin-3 has entered the release pipeline?

I have several machines set up with cygwin.   (It is a pretty minimal subset:
no X, no apache, no big database servers, etc: just basic command line tools.)
 I try to keep the machines exactly in sync.  I generally update cygwin once
or twice a year, and sync all the machines to the same version of cygwin at
about the same time.  I have been doing this for many years, and have a
procedure that works well for me.  (Roughly, I use cygwin-setup to update one
machine, test and burn it in for a few days, and then clone it to the other
machines by other means.)

I try to avoid the "bleeding edge".  I follow the cygwin mailing list, and try
_not_ to take a new major version of base cygwin until it settles down, in
terms of mailing list traffic.  Right now, it feels to me like I should wait
awhile before moving to cygwin-3.

But now and then I need to upgrade a specific package outside of my full
cygwin update cycle.  E.g., right now I would like to upgrade just git.

So:  Assume for the moment that the latest git package release on the mirrors,
has been built against cygwin-3 base.  Am I reasonably safe to assume it will
still work with cygwin-2.11.2?  Does this generalize to all, or at least most,
other packages?

Thank you all for your advice.
