Releases

Anybody can propose a release. First bump the version in Makefile, make sure CHANGELOG.md is up to date, and make sure tests are passing. Then open a Pull Request from master into the release branch. Once a maintainer approves and merges, CircleCI will build a release and upload it to Github.
