- Disable interactive progress display when no terminal size is available.
[3936](https://github.com/pulumi/pulumi/pull/3936)

- Mark `ResourceOptions` class as abstract in the .NET SDK. Require the use of derived classes.
[3943](https://github.com/pulumi/pulumi/pull/3943)

- Support stack references in the Go SDK.
[3829](https://github.com/pulumi/pulumi/pull/3829)

- Fix the Windows release process.
[3875](https://github.com/pulumi/pulumi/pull/3875)

- Avoid writing checkpoints to backend storage in common case where no changes are being made.
[3860](https://github.com/pulumi/pulumi/pull/3860)

- Add information about an in-flight operation to the stack command output, if applicable.
[3822](https://github.com/pulumi/pulumi/pull/3822)

- Update `SummaryEvent` to include the actual name and local file path for locally-executed policy packs.

- Add support for aliases in the Go SDK
[3853](https://github.com/pulumi/pulumi/pull/3853)

- Fix Python Dynamic Providers on Windows.
[3855](https://github.com/pulumi/pulumi/pull/3855)

- Fix a stack reference regression in the Python SDK.
[3798](https://github.com/pulumi/pulumi/pull/3798)

- Fix a buggy assertion in the Go SDK.
[3794](https://github.com/pulumi/pulumi/pull/3794)

- Add `--latest` flag to `pulumi policy enable`.

- Breaking change for Policy which removes requirement for version when running `pulumi policy disable`. Add `--version` flag if user wants to specify version of Policy Pack to disable.

- Fix rendering of Policy Packs to ensure they are always displayed.

- Primitive input types in the Go SDK (e.g. Int, String, etc.) now implement the corresponding Ptr type e.g. IntPtr,
StringPtr, etc.). This is consistent with the output of the Go code generator and is much more ergonomic for
optional inputs than manually converting to pointer types.
[3806](https://github.com/pulumi/pulumi/pull/3806)

- Add ability to specify all versions when removing a Policy Pack.

- Breaking change to Policy command: Change enable command to use `pulumi policy enable <org-name>/<policy-pack-name> latest` instead of a `--latest` flag.

- Publish python types for PEP 561
[3704](https://github.com/pulumi/pulumi/pull/3704)

[3733](https://github.com/pulumi/pulumi/pull/3733)

- Improvements to `pulumi policy` functionality. Add ability to remove & disable Policy Packs.

- Breaking change for Policy which is in Public Preview: Change `pulumi policy apply` to `pulumi policy enable`, and allow users to specify the Policy Group.

- Add Permalink to output when publishing a Policy Pack.

- Add `pulumi policy ls` and `pulumi policy group ls` to list Policy related resources.

- Add `BuildNumber` to CI vars and backend metadata property bag for CI systems that have separate ID and a user-friendly number. [3766](https://github.com/pulumi/pulumi/pull/3766)

- Breaking changes for the Go SDK. Complete details are in [3506](https://github.com/pulumi/pulumi/pull/3506).

- Fix a panic in `pulumi stack select`.
