I've just uploaded this release to
New components are Maps and AVL Trees.
I have reworked the Iteration scheme; one obvious result is that
iterating over Lists is much faster. Another is that this release WILL
NOT WORK WITH GNAT 3.10p (hence the inordinate delay since the last
release!) 3.11p is fine, as is OA 7.1 with restrictions (I've included
special versions of the test programs, as *_aonix.adb).
