Changelog Generator Free Online Tool 2026

Why Changelogs Matter

A changelog is a curated, human-readable record of notable changes in each version of a project. It's different from a raw git log — it's written for users and developers who need to understand what changed, not for machines. The Keep a Changelog project defines a widely-adopted format that makes changelogs consistent and easy to parse.

Keep a Changelog Format

# Changelog

All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

Automating Changelogs with Conventional Commits

Conventional Commits is a commit message specification that enables automated changelog generation. Commit messages follow the format type(scope): description:

• feat: add dark mode → Added section
• fix: correct timezone bug → Fixed section
• feat!: redesign API (breaking change) → triggers major version bump
• chore: update dependencies → not included in changelog

Tools like standard-version, release-please, and semantic-release read these commit messages and automatically generate changelogs and bump version numbers.
