Time To Upgrade Your Python: TLS v1.2 Will Soon Be Mandatory

By ris The Python Software Foundation has announced
that python.org and related sites will begin disabling the old TLS versions
1.0 and 1.1. “This change was imposed on us by our content delivery
network, Fastly, in response to a change imposed on them by the Payment Card Industry Security Standards Council. In order to continue serving websites that take credit card payments, Fastly is required to disable the old, insecure versions of TLS. Since the PSF’s servers, including PyPI, use Fastly, the old versions of TLS will be disabled as well.
