+# 2.3.0-rc1 (2024-04-18)
+## Highlights
+The 2.3.0-rc1 release is our first release candidate pre-release, meant to test all the new features and enhancement for the upcoming 2.3.0 release.
+
+There are two main new features:
+- The experimental cell-centric discrete spaces, as added in #1994. It allows having cells with not only properties but also active behaviors: the `CellAgent`. Its inspired by NetLogo's [patches](https://ccl.northwestern.edu/netlogo/bind/primitive/patches.html) but extend and generalize this concept further.
+- Full support for discrete event scheduling, as added in #2066. It allows scheduling events (like Agent actions) at any time, including non-integer timesteps.
+
+There are a lot of other features: The Jupyter visualisation now supports sliders, `NetworkGrid.get_neighbors()` supports a radius, `AgentSet.get()` can retrieve multiple attributes and there are now benchmarks to track Mesa performance during development.
+
+Finally, 2.3.0 stabilizes the `AgentSet` (including `model.agents`), making it the first experimental Mesa feature that is taken out of it's experimental phase.
+
+Install this pre-release with:
+```
+pip install --pre mesa
+```
+We would love feedback before we release 2.3.0 stable in ~1 week.

+**Full Changelog**: https://github.com/projectmesa/mesa/compare/v2.2.4...2.3.0-rc1
+
+# 2.2.4 (2024-01-26)
+## Highlights
+Mesa v2.2.4 is a small but important bugfix release for the 2.2 release series. It fixes an essential bug in where agents weren't shuffled in the `BaseScheduler`, affecting mainly 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 and @quaquel 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
