A Canary release is a deployment strategy used in software development and release management. It involves rolling out a new version of an application or service to a small subset of users or infrastructure before making it available to the entire user base or production environment. The Canary release allows developers to test the new version in a controlled manner, monitoring its performance, stability, and user feedback. This approach helps identify potential issues or bugs early on before a wider rollout, ensuring a smoother and more reliable deployment process.
