changelog
Domain: Version Control
🎯 Motivation
A changelog is a file that records notable changes for each release in human-readable language. It helps users understand what is new, fixed, or broken when they decide whether to upgrade.
📋 Concrete Example
A CHANGELOG.md file lists under ## v2.1.0 - 2026-08-01 the entries “Added: dark mode” and “Fixed: login crash on empty password”, grouped by change type.
🔗 Analogy
A changelog is like a “What’s New” sticker on a video game update. Players read it to decide if the patch is worth downloading.
