[q-lang-users] Q 7.11 RC3 available

[Albert G. <Dr....@t-...>]

I'm currently uploading Q 7.11 RC3, it should soon be available in
testing (the source tarball is already there):
http://sourceforge.net/project/showfiles.php?group_id=96881&package_id=188958

What's new in RC3: Jiri Spitz' much improved AVL tree implementation for
the container types (bag.q, dict.q, hdict.q, set.q). The improved
algorithm has its origin in the SWI-Prolog implementation of association
lists by R.A.O'Keefe and Jan Wielemaker (see assoc.pl at
http://www.swi-prolog.org). Jiri rewrote the algorithm in Q and also
added the deletion operations which were missing in the Prolog version.
Tests indicate that updating the new data structures is at least twice
as fast for large trees, quite a notable improvement!

Everyone who has programs making use of the bag, set, dict and hdict
data types, please take the new version for a test drive and report bugs
asap. Thanks. :)

Cheers,
Albert
