[ACT-R-users] ACT-R software update

[db30 at andrew.cmu.edu]

The ACT-R 7 software available from the software page on the ACT-R website
<http://act-r.psy.cmu.edu/software/> has been updated.  The current version
is now 7.13.5-<2880:2019-06-26>.

The changes with this update are mostly to improve the software performance.

One new feature in that regard is the addition of a "Lisp only" mode which
removes the external communication mechanism and allows the software to be
loaded without having QuickLisp installed, like the older versions (7.5 and
before).  Using the tutorial models as tests, the Lisp only mode takes about
half the time to run over that set of models compared to running them with the
full version, and the Lisp only version also takes less time than it does to
run the corresponding models in version 7.5 (about 85% of the time it takes to
run in 7.5).

If you have any questions or problems with the new version please let me know.
