+- String codec name is now "idna2008" as overriding the system codec
+  "idna" was not working.
 - Fix typing error for codec encoding
-- Remove 'setup.py' to complete migration to pyproject.toml
+- "setup.py" has been restored for this release due to some downstream
+  lack of adherence to PEP 517. Should be removed in a future release
+  so please prepare accordingly.
+- Removed reliance on a symlink for the "idna-data" tool to comport
+  with PEP 517 and the Python Packaging User Guide for sdist archives.
 - Added security reporting protocol for project
