Full Release Notes

## 3.243.0 (2026-05-22)


### Features

- [cli] Make the `pulumi project new -y` command write a minimal project file with no template
  [#22847](https://github.com/pulumi/pulumi/pull/22847)

- [cli] Allow coding agents to create claimable temporary accounts when not authenticated

- [cli] Suggest `pulumi neo` in `pulumi preview` and `pulumi up` diagnostics output
  [#23326](https://github.com/pulumi/pulumi/pull/23326)

- [sdk] Add `List` to the Go `plugin.Provider` interface, wired to the streaming `ResourceProvider.List` RPC
  [#23287](https://github.com/pulumi/pulumi/pull/23287)

- [sdkgen] Reserve the package names 'pulumi' and 'input' for internal use
  [#23321](https://github.com/pulumi/pulumi/pull/23321)
