release notes

release notes — Official documentation that describes the new features, bug fixes, improvements, and known issues in a software version released to users.

In simple English

Release notes are a critical communication tool between development teams and end users. They document everything important about a new software version in language that both technical and non-technical users can understand. Release notes typically include new features, performance improvements, security patches, bug fixes, and sometimes known limitations or deprecated features. In tech companies, release notes are usually written by product managers, tech writers, or senior developers and published alongside the actual software release. They may appear on a company website, in-app, or in email announcements. Release notes help users understand what to expect, why they might need to update, and any actions they should take. Release notes differ from changelogs or commit messages because they focus on user-facing changes rather than internal technical details. A changelog might list hundreds of commits, while release notes summarize only the most important changes for users.

User wants to understand what release notes are, how to write them, or where to find them for a software product.
