Fwd: NetLogo 4.1 released

[Owen Densmore]

The major new upgrade of netlogo is now outa beta!

This release seems to be a serious step forward!  I've tried it on my  
tutorial  site and works fine.  One huge plus is that you can run more  
models as web page applets, so the GIS extension, for example, should  
be available for web use.

The transition guide is very useful and I updated all the tutorial  
apps in minutes.

Main problem I encountered was:
+ set [variable] of ... is no longer allowed; use ask ... [ set
   variable ... ] instead

Owen,

The moth model has not been updated since hector was a pup.  Is that bad
manners?  Bad self promotion?  I dont think models are forward compatible.
Or is it that the program is not backward compatible with its models.  I
think Shawn might be willing to upgrade  it, if I asked him nicely.   Nick

I want to correct a statement I made earlier.  The GIS extension does  
not work as an applet when accessing GIS files.  Thanks to Pietro  
Terna's trying to make a GIS applet, we were able to determine the  
problem and to have it put on the NetLogo future issues list.
