Tags
Pre-1.0 tags are provided for reference only, and do not designate releases with ongoing support. Bugfixes will not be backported to older tags.
Tags follow semantic versioning. In particular, as the major version is zero:
- breaking API or behavior changes will increment the minor version component.
- non-breaking changes will increment the patch version component.
