Breaking Changes
- The `--branch` option was replaced by a general `--ref` option, which accepts branch names and tags (4).
- Same for the `branch` key in the shortcut definition.
- Prefer a local configuration file **over** a global configuration file.
New features
- If the job name, remote or ref name is not configured in the shortcut, it can be specified using options.
- Better checks for valid shortcut configurations.
Fixes
- Fix an issue where the `job_token` and `oauth_token` authentication tokens where not propagated correctly (5).
