-Furthermore, a new `shuffle_do()` method for AgentSets provides a faster way to perform `shuffle().do()` ([#2283](https://github.com/projectmesa/mesa/pull/2283)). The GroupBy class gained `count()` and `agg()` methods to count the number of agents in groups and aggregate variables of them ([#2290](https://github.com/projectmesa/mesa/pull/2290)). The `CellCollection.select` method was updated to use `at_most` instead of `n`, aligning with the AgentSet API ([#2307](https://github.com/projectmesa/mesa/pull/2307)). Additionally, the Cell class now features a dedicated `neighborhood` property for direct neighbors (default radius=1) and a `get_neighborhood` method for larger radii ([#2309](https://github.com/projectmesa/mesa/pull/2309)).

+In the experimental Cell Space, the `CellCollection.select` method was updated to use `at_most` instead of `n`, aligning with the AgentSet API ([#2307](https://github.com/projectmesa/mesa/pull/2307)).

 Finally, SolaraViz received updates improving its interface and performance ([#2299](https://github.com/projectmesa/mesa/pull/2299), [#2304](https://github.com/projectmesa/mesa/pull/2304)). Cell connections in grids and networks are now public and named for more intuitive agent movements ([#2296](https://github.com/projectmesa/mesa/pull/2296)). The Model class initialization process was simplified by moving random seed and random object creation to `__init__` ([#1940](https://github.com/projectmesa/mesa/pull/1940)). Documentation has been extensively updated, including enforcing Google docstrings ([#2294](https://github.com/projectmesa/mesa/pull/2294)) and reorganizing the API documentation ([#2298](https://github.com/projectmesa/mesa/pull/2298)) for better clarity and navigation.
