Conventional Commits is a specification for creating standardized commit messages, improving readability and automation. Messages follow a `<type>[optional scope]: <description>` format, with optional body and footers. Types like `fix` and `feat` correlate with semantic versioning (PATCH and MINOR, respectively), while `BREAKING CHANGE` indicates a major version bump. This standardization aids in automated changelog generation, version bumping, and streamlined collaboration. Tools can leverage these structured messages for various automation tasks.
