New Code Examples:

Sample Model Updates:

Our Chemistry & Physics folder now contains enough examples that can be classified as “Materials Science” that they deserve their own folder. This means a number of models have been physically moved into this new sub-folder of Chemistry and Physics: - Solid Diffusion - Polymer Dynamics - Lennard-Jones - Dislocation Motion and Deformation - Crystallization Models

Also in this folder are the MaterialSim models. They have been physically moved to the Curricular Models folder, but will be cross-referenced in Chemistry & Physics/Materials Science.

Alternative Visualization Updates:

Curricular Model Updates:

Note, the above BEAGLE models have now been physically moved into the Curricular Models/BEAGLE Evolution/ folder. In the Models Library browser, they will appear cross-referenced in the usual places.

Code Examples Updates:

HubNet Activities Updates:

All HubNet models now include a citation for the HubNet software and their web links have been updated. This resulted in a change to 37 models in total.

IABM Model Updates:

Fixed inconsistent bracket styling across IABM Textbook models. This resulted in changes to 12 models.

Feature Changes

The premier feature for this release is an Extension Manager for installing and updating extensions, which is available under the Tools menu. Using extensions with NetLogo could be a painful process: manually finding them, downloading them, and getting them correctly installed in the NetLogo application. The extensions manager addresses these issues by automating the installation of many 3rd-party extensions, and the updating of the bundled extensions between NetLogo releases. All done easily from within the application. In fact, if you open a model that requires an extension you don’t have installed that it knows about, the Extension Manager will ask if you’d like to download and install it right on the spot, without any extra effort

We welcome external contributions to the extensions library! If you have developed a NetLogo extension and want to make it available to NetLogo users in the Extension Manager, see these instructions: https://github.com/NetLogo/NetLogo-Libraries#submitting-pull-requests

We’ve introduced a new subfolder in the Sample Models/Social Science folder: Economics. With this new folder, several models have been moved. The following models are now in the Social Science/Economics folder:

With the introduction of the new variadic ifelse and ifelse-value primitives, the Models Library has been updated to reflect this new functionality. These updates are divided into three major sections:
