[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.

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
