Yes, that's the currently supported release.

I believe Robert Dewar said here that the gcc releases would be the
public releases of GNAT, but I'm not sure, and that may change.

As a paying customer of ACT, that's what I want them to do :).

Not precisely. I'm not speaking for ACT, but what I remember of
previous discussions, and can extrapolate from current behavior, is
that ACT will continue to make "internal, customer" releases of GNAT.
They will also continue to dump changes into the gcc tree. There will
not necessarily be synchronized releases; there is no need. But in
general, the gcc tree will track the GNAT releases. I would not be
surprised to see lead/lag times of a year, though (in either
direction).

apparently the gcc developer mailing list is where this is mostly
discussed. I have not tried to wade thru it.
