debchange is a command-line tool used to manage Debian changelog files (debian/changelog). It simplifies tasks such as adding new changelog entries, incrementing package versions, and ensuring proper changelog formatting according to Debian policy.

It automates many tedious steps involved in updating the changelog, reducing the risk of errors and saving time. The tool typically interacts with version control systems and text editors to streamline the changelog management process. debchange ensures the changelog adheres to Debian packaging standards, which is critical for building and distributing Debian packages properly. It supports different workflows, including those for both maintainer uploads and non-maintainer uploads (NMUs). Its versatility makes it invaluable for Debian package maintainers and developers.

It requires a properly structured debian directory within your package source. Incorrectly formatted changelogs can cause build failures.

debchange can be configured through environment variables and configuration files (e.g., ~/.devscripts). This allows customizing the editor used, GPG signing behavior, and other aspects of its operation.

Creating a new changelog entry with the version number 1.0-1:
debchange -n 1.0-1

Appending a message to the last changelog entry:
debchange -a "Fixes a minor bug."

Creating an NMU changelog entry:
debchange -N

debchange has been part of the devscripts package for a significant period. It was developed to standardize and ease Debian changelog management. Its evolution has mirrored the evolving requirements of Debian packaging policy. Over time, features like NMU support and integration with version control systems were added to address common development workflows.
