2.1.0

This is a feature release, which includes new features and removes previously deprecated features. The 2.1.x branch is now the supported bugfix branch, the 2.0.x branch will become a tag marking the end of support for that branch. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades.
