With this release, Amplify Console adds new pattern-based branch deployment features allowing developers to automatically create and delete custom sub-domains every time a branch is added or removed from a Git repository. This enables developers to access new feature branches at familiar URLs (e.g. feature.mydomain.com) without logging in to the console to set up new sub-domains. Additionally, deleting a branch from the Git repository will automatically delete the branch along with the custom sub-domain in the Amplify Console.
