- The logic for attaching volumes has been changed so that attachdetach controller attaches volumes immediately when a Pod's PVCs are bound, preventing a problem that caused pods to have extremely long startup times.

### Bug or Regression

- Add `/sys/devices/virtual/powercap` to default masked paths. It avoids the potential security risk that the ability to read these files may offer a power-based sidechannel attack against any workloads running on the same kernel.

- Kube-apiserver: Made the subresources `pods/exec`, `pods/attach`, and `pods/portforward` require `create` permission for both SPDY and Websocket API requests. Previously, SPDY requests required `create` permission, but Websocket requests only required `get` permission. This change is gated by the `AuthorizePo...

- Added a feature to report an event about a Pod if kubelet observes a failed attach operation, even if the kubelet is running with `--enable-controller-attach-detach=false`. ([#124884](https://github.com/kubernetes/kubernetes/pull/124884), [@carlory](https://github.com/carlory))
