It fixes an essential bug in where agents weren't shuffled in the `RandomActivation` scheduler (effectively making it sequential activation)([#2007](https://github.com/projectmesa/mesa/pull/2007)). It also fixes a small behaviour change in `RandomActivationByType.agents_by_type()` ([#1996](https://github.com/projectmesa/mesa/pull/1996)). Furthermore, this release adds an internal clock to the `Model`, which allows to use a Mesa model without a scheduler (using the `AgentSet` API)([#1942](https://github.com/projectmesa/mesa/pull/1942)). + +Updating from previous 2.2 releases is highly recommended, especially when using the `RandomActivation` scheduler. + +## What's Changed +### 🛠 Enhancements made +* refactor: Remove dependence on model.schedule, add clock to Model by @rht in https://github.com/projectmesa/mesa/pull/1942 +### 🐛 Bugs fixed +* Fix AgentSet inplace shuffle (and thus RandomActivation), add tests by @EwoutH in https://github.com/projectmesa/mesa/pull/2007 +* fix: Reverse dict key and value for agents_by_type by @rht in https://github.com/projectmesa/mesa/pull/1996 + +**Full Changelog**: https://github.com/projectmesa/mesa/compare/v2.2.3...v2.2.4 + # 2.2.3 (2024-01-22) ## Highlights diff --git a/mesa/__init__.py b/mesa/__init__.py index 6299bb351f4..ac3d495d91d 100644 --- a/mesa/__init__.py +++ b/mesa/__init__.py @@ -25,7 +25,7 @@ ] __title__ = "mesa" -__version__ = "2.2.3" +__version__ = "2.2.4" __license__ = "Apache 2.0" _this_year = datetime.datetime.now(tz=datetime.timezone.utc).date().year __copyright__ = f"Copyright {_this_year} Project Mesa Team"
