We are using GitHub Releases for our release workflow. GitHub Releases are based on git tags.

• CircleCI - for Linux builds
• Travis CI - for OSX builds
• AppVeyor - for Windows builds

We only use lightweight tags for releases. This is because as of this writing, AppVeyor cannot start a build when you use annotated tags. See this discussion for more information.

For the tag name, we follow the format v{major}.{minor}.{patch}. For example:

v1.0.0
v1.2.3-rc
v1.2.3-beta

Before starting the release workflow, be sure to update the version information in cmd/version.go. After that, the release can be done like this:

$ git checkout master
$ git pull
$ git tag v1.0.0
$ git push --tags
