multicz 1.6.0

Multi-component versioning for monorepos: bump apps, charts, and images independently from conventional commits.

multicz

Multi-component versioning for monorepos. Bump a Python app, its Docker image, and the Helm chart that deploys it from a single conventional-commit history - each with its own version line and its own git tag.

Install

uv tool install multicz   # or: pipx install multicz / pip install multicz

Quickstart

# 1. scaffold a multicz.toml in the repo root
multicz init

# 2. see what would bump from the current commit window
multicz changed
multicz explain api

# 3. apply the bump (writes version files + changelog, commits, tags)
multicz bump --commit --tag

# 4. ship it
git push --follow-tags

For multi-component setups (api + chart, app + image + helm, ...), declare each component's paths in multicz.toml and let mirrors and triggers cascade related versions. See the docs for the full configuration reference.

What it does

• Per-component versions - each component has its own version line and its own git tag (api-v1.2.0, chart-v0.5.0).
• Conventional-commit driven - feat: → minor, fix: → patch, BREAKING CHANGE: → major. Scopes route the bump to the right component.
• Mirrors and triggers - bump api 1.2.0 → 1.3.0 and the Helm chart's appVersion follows; the chart's own version cascades a patch.
• No network, no auto-updates. Pure git + filesystem. Same input yields the same plan byte-for-byte.
