3.0.0

This is a feature release, which includes new features and removes previously deprecated code. The 3.0.x branch is now the supported bug fix branch, the 2.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.
