We've just been alerted that this update fixes a security vulnerability:

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects requests The Requests package through 2.19.1 before 2018-09-14 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network.

Affected versions: ["<= 2.19.1"]
