Canary Release

A canary release is a software deployment strategy where a new version of an application is gradually rolled out to a small subset of users before releasing it to everyone. This method allows developers to monitor for issues and gather feedback without affecting all users. The term comes from the practice of using canaries in coal mines to detect dangerous gases; if the canary showed signs of trouble, miners would know to take action. Similarly, in a canary release, if problems arise, developers can halt the release and fix issues before a wider rollout.
