v3.0 alpha 2 (pre-release)

Highlights

In Mesa 3.0 alpha 2 (v3.0.0a2) we've done more clean-up in preparation for Mesa 3.0. We now require super().__init__() to run on initializing a Mesa model subclass and fixed a bug in our Solara space_drawer.

A new feature was added in #2219, which now also allows AgentSet.do() to take any callable function, instead of only a string referencing to an Agent method. The argument name was changed from method_name to method.

We're also working hard on our example models. All model warnings were resolved and we've replaced a lot of schedulers with simpler and more flexible AgentSet functionality. Checkout our open issues if you want to help improve our example models further!

You can update to this version as usual with pip install mesa --upgrade --pre.
