v2.2.4

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). It also fixes a small behaviour change in RandomActivationByType.agents_by_type() (#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).

Updating from previous 2.2 releases is highly recommended, especially when using the RandomActivation scheduler.
