 - Added optional facet articulation to the :ref:`facetSRPDynamicEffector` module.
 - Fixed a bug where the legacy variable logging API would either, not log at all or log at a rate different to the
   requested rate.
+- Updated versioning to better follow the `semantic versioning <https://semver.org>`_ standard, in the format 
+  ``MAJOR.MINOR.PATCH``. Releases will increment the minor version number, while pull requests into develop will 
+  automatically increment the patch number. This allows users to reference/require specific versions of Basilisk 
+  outside of the release cycle.
