Generate clean, professional changelogs from git commit history.

Quick Start

python3 scripts/changelog_gen.py
python3 scripts/changelog_gen.py --since v1.0.0 --group
python3 scripts/changelog_gen.py --since v1.0.0 --until v2.0.0 --format json
python3 scripts/changelog_gen.py --repo /path/to/project --since "2026-01-01" -o CHANGELOG.md

Features

Conventional commit parsing — auto-detects feat, fix, docs, refactor, perf, test, build, ci, chore, revert
Breaking change detection — from ! suffix or BREAKING CHANGE in body
Grouped output — organize by commit type with --group
Tag ranges — generate changelogs between any two tags or refs
Dual format — markdown (default) or JSON
File output — write directly to CHANGELOG.md with -o
No dependencies — Python stdlib + git

Options

`--format md\|json`	Output format (default: md)
