A changelog is a vital document in software development that records all the changes made to a project over time. It serves as a historical record, allowing contributors and users to see what updates were made, when they occurred, and the nature of those updates. This transparency is crucial for accountability and helps in tracking the evolution of the software.

Changelogs typically include information such as new releases or versions, their release dates, and details about changes affecting specific files or functions. They are usually organized in reverse chronological order, with the most recent changes listed first. While there are no strict standards for what to include, common practices suggest documenting significant changes, rationale behind modifications, and any additional relevant information ⁵.

Maintaining a changelog can improve project management and communication among team members, making it easier to understand the project’s progress and history.
