When using the Azure Pipeline Pulumi task in a DevOps pipeline, is there a way to detect simply if there is _any_ change in a stack? We want to require a manual validation step in case the infrastructure is going to change, but the only way to check that I can think of is to run `pulumi preview --json` manually in a PowerShell script, parse the JSON output and act on whether there are any modifications.

Yeah I think what you are suggesting is probably the best way to do that right now. There is an `--expect-no-changes` flag that you can pass to `preview` command that would fail the command if there were changes. But I don’t think that is too helpful for what you are looking to do perhaps.

A multi-stage pipeline with an approval between a stage with the pulumi task doing `pulumi preview` and a stage with a pulumi task doing the `pulumi up`?

But how does one define the condition that the approval should only be required when there are some changes detected by `pulumi preview`? I already started putting together a solution based on `pulumi preview --json`, might share it if it proves to be stable.
