#### Fixes

- [`KT-62381`](https://youtrack.jetbrains.com/issue/KT-62381) K/Wasm: (re)publish libraries with 1.9.20-Beta2 (or newer if available)
- [`KT-62656`](https://youtrack.jetbrains.com/issue/KT-62656) Drop `@AllowDifferentMembersInActual` from stdlib

## Known Issues

- The etcd and KMS plugin health checks are not exposed in the new `livez` and `readyz` endpoints. This will be fixed in 1.16.1.
- Systems running `iptables` 1.8.0 or newer should start it in legacy mode. Please note that this affects all versions of Kubernetes and not only v1.16.0. For more detailed information about the issue and how to apply a workaround, please refer to the official documentation

- The `ServerSideFieldValidation` feature has graduated to beta and is now enabled by default. Kubectl 1.24 and newer will use server-side validation instead of client-side validation when writing to API servers with the feature enabled.
