On https://pypi.org/project/synapseclient/, in the left panel in Project Links there is a link to Homepage that refers to 'https://synapse.sagebase.org'. That's an old link that should be replaced by 'https://www.synapse.org'.
PyPI
Change merged. It will take affect with the next pypi deploy.
This validation should be easy 😀
Can you validate that the Homepage link at https://test.pypi.org/project/synapseclient/ is updated to www.synapse.org, e.g.
Whereas before and on prod pypi it is out of date (will be updated when this release goes out).
Verified fixed.
