We should be able to simplify the rules for comparable or delegate some of them
elsewhere since we have a section that clearly defines how interfaces implement
other interfaces based on their type sets. But this should get us going for now.

### Kubernetes release cadence change

- Kubectl port-forward for Windows containers was added in v1.15. To use it, you’ll need to build a new pause image including WinCAT. ([#75479](https://github.com/kubernetes/kubernetes/pull/75479), [@benmoss](https://github.com/benmoss))
- We’re working to simplify the Windows node join experience with better scripts and kubeadm. Scripts and doc updates are still in the works, but some of the needed improvements are included in 1.15.  These include:

- Hashing of KeyID in Logs
  
  This release adds a feature to hash the `KeyID` values in the logs. The `KeyID` values are sensitive information that should not be exposed in plain text in the logs. By hashing the `KeyID` values, we can protect the confidentiality of the data while still being able to log the necessary information. ([#118988](https://github.com/kubernetes/kubernetes/pull/118988), [@nilekhc](https://github.com/nilekhc)) [SIG API Machinery, Auth and Testing]

- [`KT-61686`](https://youtrack.jetbrains.com/issue/KT-61686) Check and update places in compiler and IDE where we are saying that MPP is experimental/Beta/Alpha
- [`KTIJ-27058`](https://youtrack.jetbrains.com/issue/KTIJ-27058) Wizard's KMM application failed to build in 232 AS
