Until most (if not all) users switch to use Python client version 1.9.0, version_check is still depends on the S3 bucket to tell users to upgrade their client. Therefore, we still need to update the S3 bucket.
The S3 bucket: http://versions.synapse.sagebase.org/synapsePythonClient
The new location to check: https://raw.githubusercontent.com/Sage-Bionetworks/synapsePythonClient/master/synapseclient/synapsePythonClient
, is it possible to do a redirect from the s3 bucket url to the github raw url? If so, it would simplify the release process for the Python client.
