Pulumi Automation API adds `install` for NodeJS, Python, and Go

When a NodeJS, Python, or Go Automation API workflow needs the Pulumi CLI at runtime, call that language’s `install` interface to download and install it. The default install uses the CLI version matching the SDK and places it under `~/.pulumi/versions/<version>`; pass the returned command to the workspace that runs the stack.

const pulumiCommand = await PulumiCommand.install(); const stack = await LocalWorkspace.createOrSelectStack(args, { pulumiCommand });

pulumi state promote converts stateful snippets into Pulumi program code

When promoting a stateful snippet, run `pulumi state promote <snippet-name>` from a real Pulumi project; it generates program code, prints the files, and removes the snippet while retaining its resources in stack state.

pulumi plugin install adds --parallel with improved progress rendering

When you need to preinstall the plugins required by the current Pulumi project, run `pulumi plugin install --parallel <N>` from that project. It installs concurrently, with a default maximum of 4; the release note reports improved rendering for simultaneous progress bars.

pulumi do assigns identifiers to existing stack resources

When an input expression needs to refer to a resource in the current stack, use its auto-assigned identifier in place of its URN. Run `pulumi do show-resources` to inspect those identifiers.

pulumi up, preview, and destroy accept --ignore-protect

When an update, preview, or destroy must delete a protected resource, add `--ignore-protect` to that Pulumi command. It allows the operation to proceed without first unprotecting the resource in state.

Pulumi policy packs can use executable binaries

When running a Pulumi preview with an executable policy pack, pass the executable’s path to `--policy-pack`. A neighboring `PulumiPolicy.yaml` may provide the pack’s `version` and `description`.
