+
+**DAS-2180** - Adds pip installable library.
+
+This release is a refactor that extracts browse image generation logic from the
+harmony service code. There are no user visible changes to the existing
+functionality.  The new library,
+[hybig-py](https://pypi.org/project/hybig-py/), provides the `create_browse`
+function to generate browse images, see the README.md for details.
