[starlogo-users] Announcing StarLogo TNG Preview 4.1

[Eric Klopfer]

We are pleased to officially announce the release of StarLogo TNG 
Preview 4.1.

This release is hot on the tail of the unofficial release of Preview 4. 
  If you downloaded StarLogo TNG in the past few days, you should update 
to Preview 4.1, which contains some additional bug fixes.

There are a number of enhancements and bug fixes in this version.  In 
parallel, we have been working on redesigning the blocks interface from 
scratch.  That work is well along the way, and we hope to release the 
first full Beta with these features in the near future.  In the mean 
time, Preview 4.1 is quite stable and fun, and offers a number of 
valuable improvements over Preview 3.

You might also be interested in the StarLogo TNG tutorial on 
Complexity, which is linked to from the front page of StarLogo TNG

Enjoy!

Preview 4 to Preview 4.1

Fixed two last minute bugs:
-	Fixed rounding error that when agents are being drawn on patches
-	Fixed collision bug where collisions where being duplicated that has 
been around for a long time.  NOTE THIS WILL REQUIRE A CHANGE IN

AND BOTTOM OF SUCH COLLISIONS SHOULD BE DUPLICATED.
