Changelog
A changelog is a file or document that chronologically records notable changes made to a software project, such as new features, bug fixes, and deprecations. It serves as a historical record and communication tool for developers, users, and stakeholders to track the evolution of a project. Typically maintained in plain text formats like Markdown, it helps ensure transparency and facilitates version management.
Developers should learn and use changelogs to improve collaboration and project maintainability, especially in team environments or open-source projects where tracking changes is critical. They are essential for documenting releases, helping users understand updates, and complying with semantic versioning practices, which reduces confusion during deployments and upgrades.
