 ## latest
 
+- Fixed naming of variables tracking active simulations in the `MicroManager` [#273](https://github.com/precice/micro-manager/pull/273)
 - Improved load balancing of inactive simulations by tracking a small amount of time [#272](https://github.com/precice/micro-manager/pull/272)
 - Added the exported field `model_resolution` when using model adaptivity [#271](https://github.com/precice/micro-manager/pull/271)
 - Fixed model adaptivity active simulation mask generation for 0 local simulations [#270](https://github.com/precice/micro-manager/pull/270)
