[ACT-R-users] New ACT-R 6.0 release

[db30 at andrew.cmu.edu]

ACT-R 6.0 v1.4 [r1261] is now the current version on the ACT-R
web site.

The biggest change with this release is in the AGI tools which
now support multiple windows both within and between models.  A
couple of other notable changes are:

- The S-log(fan) calculation now considers negative results to
be 0 and prints a warning when it results in a negative value,
but the old behavior (using the negative value) can be restored
by setting the new parameter :nsji to t.

- Sgp now sorts the modules and parameters alphabetically when
it prints all of them.

- The Control Panel window in the Environment has a scrollbar
now so all the buttons can be accessed when using a small
display.

- The audio module now provides a model with a way to detect
when a sound ends because it will automatically update the
chunk in the aural-location buffer with the offset time when
the sound stops.  There is also an additional request parameter
that can be provided for aural-location requests called
:finished that can take a value of t or nil to indicate whether
only sounds which have completed or sounds which are ongoing
should be considered.
