importing worlds is a lot faster now
Programming Guide now has preliminary documentation on tasks
tweaks:
renamed Run tab back to Interface
plotting code inside plots is now wrapped in with-local-randomness

NetLogo 5.0beta1

March 18, 2011

features:
Info tabs can now include images and rich formatting, using the "Markdown" markup language
Unicode is supported throughout the application
GUI is internationalized (but not localized yet except for U.S. English and a preliminary Spanish localization))
plotting code can now be removed from the Code tab and put inside each plot instead
the default speed of models is now authorable (via a target frame rate setting)
buttons can now optionally disable until the tick counter starts (e.g., to disable "go" until "setup" is pressed)
language changes:
you must now use reset-ticks to start the tick counter before using tick or tick-advance; in existing models, clear-all is autoconverted to __clear-all-and-reset-ticks; the reset-ticks part should be moved to the end of your setup procedure
plotting code in plots is normally triggered by reset-ticks and tick, but may also be triggered by new primitives setup-plots and update-plots
"tasks" let you store code to be run later
also known as first-class functions, closures, and lambdas
two new types: command tasks and reporter tasks
new primitives: task, is-command-task?, is-reporter-task?
these existing primitives now accept tasks: run, runresult, foreach, map, reduce, filter, n-values, sort-by
improved overall list performance. lput, last, butlast, item, replace-item now take near-constant time instead of linear time. internally lists are now hash tries instead of singly linked lists
new primitive sort-on lets you say e.g. sort-on [size] turtles
new primitive error lets you cause a runtime error
random-normal now rejects negative standard deviations
HubNet:
activities can now be run headless
hubnet-set-client-interface is no longer required
theoretical support for multiple simultaneous client types (undocumented)
removed obsolete hubnet-broadcast-view primitive
other fixes and changes:
tabs renamed to Run/Info/Code (formerly Interface/Information/Procedures); this change is experimental and may not survive till the final release; w are interested in your feedback on this renaming.
NetLogo 3D now uses a .nlogo3d file extension instead of .nlogo
the startup procedure no longer runs automatically when running headless, or in background BehaviorSpace runs
BehaviorSpace now uses an official Scala release (2.8.1) rather than a nightly build
on Mac OS X, the app now runs in 64 bit mode by default (on 64 bit machines)
upgraded installer for Windows users that we hope will fix some installation issues
