Complete manual control over version generation. Unlike zerv flow, version
generates versions as-is, without opinionated auto-bumping logic; see the
version concepts page.
Schema variants
22 presets (standard and calver families) and custom RON schemas. See the
schema system for how schemas work.
VCS overrides
Override any VCS-detected value:
Version bumping
Field-based bumps (major/minor/patch, stackable) and schema-based bumps:
Component overrides
Fine-grained control over individual version components while preserving everything else:
Sources (git, stdin, none), output formats (semver, pep440, zerv), prefixes,
and Tera templates work the same as zerv flow; see
formats and templates. Last modified on August 21, 2026
