+# 3.0.0a2 (2024-08-21)
+## 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](https://github.com/projectmesa/mesa/pull/2218) `super().__init__()`  to run on initializing a Mesa model subclass, `Model.agents` is now fully reserved for the Model's internal AgentSet and we fixed a bug in our Solara space_drawer.
+
+A new feature was added in [#2219](https://github.com/projectmesa/mesa/pull/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`.
+
+The new Solara visualisation now allows portraying agents in different shapes, checkout some examples in [#2214](https://github.com/projectmesa/mesa/pull/2214).
+
+We're also working hard on our [example models](https://github.com/projectmesa/mesa-examples). All model warnings were [resolved](https://github.com/projectmesa/mesa-examples/pull/153) and we've [replaced](https://github.com/projectmesa/mesa-examples/pull/161) a lot of schedulers with simpler and more flexible AgentSet functionality. Checkout our [open issues](https://github.com/projectmesa/mesa-examples/issues) if you want to help improve our example models further!

 ## Highlights
 Mesa 3.0 alpha 1 (`v3.0.0a1`) is another step towards our next major version. This release introduces a name change from JupyterViz (jupyter_viz) to SolaraViz (solara_viz), to better represent the tech stack being used. It also includes two bugfixes also present in 2.3.2.
