 # Releases
 
+## Version 2.0.1
+
+Date: 2023-11-08
+
+This minor release fixes a number of bugs, including a regression introduced by the replacement of the build backend (`setuptools` for `hatchling`) which led to the `doc` folder being wrongly packaged. Many thanks to @SultanOrazbayev for their first contribution, to @musicinmybrain for spotting the regression and submitting fixes, and to the maintainers @Hoxbro, @jbednar and @maximlt for contributing to this release.
