FW: NetLogo 2.0.2 release

[Stephen Guerin]

The NetLogo development team at the Center for Connected Learning and
Computer-Based Modeling at Northwestern University is pleased to
announce the release of NetLogo 2.0.2.  NetLogo 2.0.2 is available for
free download from our site at http://ccl.northwestern.edu/netlogo/ .

We hope you enjoy it.  If you have comments or suggestions please send
them to us at [hidden email].

NetLogo 2.0.2 is primarily a bugfix release. However we have added a cool
new feature: the sound and music extension - check out one of the new code
examples that use sound.


The following is a (partial) list of changes made and new features
that have been added since NetLogo 2.0.1.

* system:
   - our bundled Java VM for Windows is now Sun 1.4.2_05 (was
     1.4.2_04)
* content:
   - improved models: Buffer (no longer unverified), Random Balls
     (bugfix)
   - new code examples: Network Example, Vision Cone Example,
     Sound Workbench, Percussion Workbench, Beatbox, Composer,
     GasLab With Sound
   - all Code Examples now have a copyright notice that clarifies
     that use of the code in them is unrestricted
* features:
   - NetLogo can now make sounds and music; this is done with a
     new, experimental "sound extension" that is also an example
     of how to use our extensions API; documentation and code
     examples for the sound extension are included, and the Java
     source code is available from our website
* engine fixes:
   - fixed 2.0.1-only bug in file-read primitive that caused it to
     fail on larger files
   - fixed bug in sort-by primitive where the original list was
     altered, instead of a copy being made
   - fixed bug in histogramming where values equal to the x max
     were assigned to the previous bin; this was arguably
     acceptable for floating point data, but simply incorrect for
     integer data; such values are now considered to fall outside
     the range of the histogram
   - fixed minor bug where exported world files sometimes
     contained a incorrectly formatted timestamp
* interface fixes:
   - shift-clicking to close an agent monitor now closes all open
     agent monitors
   - you can now put blank lines in a text box (and they will
     survive being saved and loaded)
   - errors in procedures defined first are now reported first
   - improved appearance of models library dialog on Windows
   - fixed 2.x-only bug where NetLogoLite.jar was not
     double-clickable
   - fixed bug in BehaviorSpace where if you only specified one
     value for a variable, e.g. ["foo" 3], that value was ignored
   - fixed Mac-only bug where control-clicking a button would
     trigger it (as well as opening the contextual menu)
* computer HubNet changes:
   - fixed bug that could cause a Java exception in some
     circumstances

Credits

NetLogo was designed and authored by Uri Wilensky, project leader and
director of the CCL.  The lead developer is Seth Tisue.  Many others have
greatly contributed.  HubNet was jointly designed by Uri Wilensky and Walter
Stroup.  The development of NetLogo and HubNet (both calculator and
computer versions) is part of the Participatory Simulations project --
a collaboration between Northwestern University's Center for Connected
Learning and Computer-Based Modeling (CCL) and the University of Texas
at Austin.

The design of NetLogo was supported through funding from the National
Science Foundation (grants REC 9814682, REC 0126227).  Additional
support for the design of HubNet (calculator version) was provided by
Texas Instruments.
