Full Release Notes

## 3.252.0 (2026-07-13)

### Features

- [auto] Add `import` to the generated automation APIs for NodeJS, Python and Go [#23876](https://github.com/pulumi/pulumi/pull/23876)
- [cli] Improve the error message when using Pulumi ESC with a DIY backend to suggest logging into Pulumi Cloud [#23811](https://github.com/pulumi/pulumi/pull/23811)
- [cli] Show command name for cli commands when running any command that lists logs [#23889](https://github.com/pulumi/pulumi/pull/23889)
- [cli/display] Render strings containing non-UTF8 bytes as b"<base64>" in diffs and JSON output [#23870](https://github.com/pulumi/pulumi/pull/23870)
- [cli/env] Add a `--reason` flag to `pulumi env open-request` to explain the request to approvers [#23802](https://github.com/pulumi/pulumi/pull/23802)
- [cli/state] Improve the error message when a resource URN is not found in the state for `pulumi state` commands, suggesting close-matching URNs and how to list the URNs in the stack [#23812](https://github.com/pulumi/pulumi/pull/23812)
- [pcl] Allow binding hooks to a resource's `onError` option [#23838](https://github.com/pulumi/pulumi/pull/23838)
- [sdk/nodejs] Add a `production` runtime option for Node.js projects. When set to `true` in `Pulumi.yaml`, `pulumi install` skips `devDependencies` (npm `--production`, pnpm `--production`, yarn `--production`). [#23849](https://github.com/pulumi/pulumi/pull/23849)

### Bug Fixes

- [cli] Exit with a non-zero code when a command group such as `pulumi env` is given an unknown subcommand or no subcommand at all [#23814](https://github.com/pulumi/pulumi/pull/23814)
- [cli] Fix a panic when displaying a stack-level policy violation [#23692](https://github.com/pulumi/pulumi/pull/23692)
- [cli] Make reading non-secret stack outputs and running `pulumi about` no longer require the passphrase for passphrase-encrypted stacks [#23820](https://github.com/pulumi/pulumi/pull/23820)
- [cli] Avoid `pulumi logs <command>` showing the log for the currently running command [#23887](https://github.com/pulumi/pulumi/pull/23887)
- [cli/do] Fix calling delete on PF resources that need read called first [#23837](https://github.com/pulumi/pulumi/pull/23837)
- [cli/env] Submit the change request created by `pulumi env open-request` so it is pending approval instead of being left as an unsubmitted draft [#23802](https://github.com/pulumi/pulumi/pull/23802)
- [cli/neo] Fix the initial prompt sometimes rendering above the welcome banner in `pulumi neo` [#23831](https://github.com/pulumi/pulumi/pull/23831)
- [engine] Fix importing a resource whose import identifier differs from its canonical ID causes the resource to be deleted on a subsequent update [#23834](https://github.com/pulumi/pulumi/pull/23834)
- [programgen] Deduplicate identical apply arguments to avoid unnecessary Promise.all/pulumi.all/Output.All in generated code [#22293](https://github.com/pulumi/pulumi/pull/22293)
- [sdk] Failed resource registrations will return faulted outputs, not unknown outputs [#23844](https://github.com/pulumi/pulumi/pull/23844)
- [sdk/nodejs] Fix empty node_modules folders in serialized function archives when using pnpm or symlinked workspace packages [#23866](https://github.com/pulumi/pulumi/pull/23866)

### Miscellaneous

- [sdk/nodejs] Report the TypeScript version in `pulumi about` [#23850](https://github.com/pulumi/pulumi/pull/23850)
- [sdk/nodejs] Update OpenTelemetry dependencies [#23855](https://github.com/pulumi/pulumi/pull/23855)
