👉 The Changelog Fluid is a Git hook that automates the process of updating a changelog file in a project when code changes are committed. It monitors specific files (often `CHANGELOG.md` or similar) for modifications and triggers a script to update the changelog with relevant commit messages, ensuring that the documentation remains current without manual intervention. This tool enhances efficiency by reducing the need for developers to manually update the changelog after each commit, thereby streamlining the development workflow and maintaining accurate project documentation.
