Pulumi ESC now supports a new `--override-env` flag in the Pulumi CLI that lets teams preview configuration changes — including unapproved drafts — against a stack before promoting them. The flag works with all Pulumi operations (`preview`, `up`, `refresh`, `destroy`) and supports overriding multiple environments at once, including environments imported indirectly via the import chain. This is especially useful for validating draft ESC environments as part of an approval workflow, or for one-off debugging without modifying stack config.
