-- Fix if else conditions in setup.py to correctly install modules (#285)
-- Refactor state type (#277, #278, #280, #284)
-- Refactor dynamical systems factory (#288)
+Version 6.0.0 refactors the StateType enum in state representation to be more descriptive and widely useful as well as 
+the dynamical systems factory for easier creation of these classes. This major change breaks implementations using
+StateType enums explicitly (e.g. for parameters) and dynamical systems from the prior version.
+
+See the updated documentation for usage guidelines for the DynamicalSystemsFactory.
+
+This release also includes a few new features, fixes and improvements as well as updated documentation in 
+all parts of the control libraries.
+
+### Breaking changes
+
+This release contains the following breaking changes:
+- Refactor `StateType` enum and `ParameterType` enum (#277, #278, #280, #284)
+- Relocate the `DYNAMICAL_SYSTEM_TYPE` enum to the general `dynamical_systems` namespace (#288)
+
+**state_representation**
+
+To make the `StateType` enum more descriptive and useful, individual spatial state types have been added
+and the `ParameterType` moved to a separate enum. This change helps with the translation of parameters and
+encoded states in downstream projects by allowing for greater introspection of data types from this enum.
+
+Any implementations that use `StateType` from a prior version to create parameters or compare state types should be
+updated.
+
+**dynamical_systems**
+
+The previous `DYNAMICAL_SYSTEM` enum has been removed from the dynamical system factory class and put directly in the
+general `dynamical_systems` namespace and renamed to `DYNAMICAL_SYSTEM_TYPE` to shorten the creation and to have the
+same structure as the controllers factory. 
+
+Any implementations that use the previous enum have to be updated. See the documentation for more information.
