changelog/v0.17.3.md
pulumi stack rename was added. This allows you to change the name of an existing stack in a project. Note: When a stack is renamed, the pulumi.getStack function in the SDK will now return a new value. If a stack name is used as part of a resource name, the next pulumi up will not understand that the old and new resources are logically the same. We plan to support adding aliases to individual resources so you can handle these cases. See pulumi/pulumi#458 for discussion on this new feature. For now, if you are unwilling to have pulumi up create and destroy these resources, you can rename your stack back to the old name. (fixes pulumi/pulumi#2402)
