The Agency: Preview 4.2 released

Thank you to all of you out there who downloaded Preview 4.1 and helped us track down a couple more bugs that we wanted to fix ASAP. If you downloaded p4.1 last week, please head to http://education.mit.edu/starlogo-tng/ and download p4.2.

Here's a list of the bugs fixed in this release:

• Fixed bug with collisions. Asymmetric collisions did not always get executed. (Asymmetric collisions are the ones with two different breeds.)
• Fixed a few problems related to strings.
• Provided a batch application (starlogotng-mastercontrol.bat) to disable audio on computers that don't support it. Note that this file is for the Windows version only. All versions of Mac OS X that support StarLogo TNG also support the sound feature.

The most significant problem is the asymmetric collision bug, a regression in p4.1 that may easily break your existing projects, so we strongly recommend that all users download the latest version. Sorry for the trouble!
