Release Notes

0.3.4

Other Notes

• Data providers’ usage of Quandl has been switched to Nasdaq Data Link since the Quandl python client has been discontinued and was replaced by Nasdaq Data Link. The previous Quandl url redirects to the new one at https://data.nasdaq.com/ . The userid/password and token there were preserved. There is no need to register again. More information at https://pypi.org/project/Nasdaq-Data-Link/
