Release Notes

urllib3/urllib3

### [`v1.25.11`](https://togithub.com/urllib3/urllib3/blob/master/CHANGES.rst#​12511-2020-10-19) [Compare Source](https://togithub.com/urllib3/urllib3/compare/1.25.10...1.25.11) - Fix retry backoff time parsed from `Retry-After` header when given in the HTTP date format. The HTTP date was parsed as the local timezone rather than accounting for the timezone in the HTTP date (typically UTC) (Pull [#​1932](https://togithub.com/urllib3/urllib3/issues/1932), Pull [#​1935](https://togithub.com/urllib3/urllib3/issues/1935), Pull [#​1938](https://togithub.com/urllib3/urllib3/issues/1938), Pull [#​1949](https://togithub.com/urllib3/urllib3/issues/1949)) - Fix issue where an error would be raised when the `SSLKEYLOGFILE` environment variable was set to the empty string. Now `SSLContext.keylog_file` is not set in this situation (Pull [#​2016](https://togithub.com/urllib3/urllib3/issues/2016))
