traditionally aliases for a physical, numbered register,
in the Go assembler the names <code>SP</code> and <code>PC</code>
are still treated specially;
for instance, references to <code>SP</code> require a symbol,
much like <code>FP</code>.
To access the actual hardware register use the true <code>R</code> name.
For example, on the ARM architecture the hardware
<code>SP</code> and <code>PC</code> are accessible as

     * TODO(fry): Consider copying variables (like evictsBySize) from outer class into this class.
     * It will require more memory but will reduce indirection.

    /*
     * Segments maintain a table of entry lists that are ALWAYS kept in a consistent state, so can

- 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 `AuthorizePodWebsocketUpgradeCreatePermission`...

  - DaemonSet pods now make use of scheduling features that require kubelets to be at 1.11 or above. Ensure all kubelets in the cluster are at 1.11 or above before upgrading kube-controller-manager to 1.13.

    * If the model is larger than 2GB, then we also require "exclude_conversion_metadata" flag to be set

* fix the issue that default azure disk fsypte(ext4) does not work on Windows ([#62250](https://github.com/kubernetes/kubernetes/pull/62250), [@andyzhangx](https://github.com/andyzhangx))
* gitRepo volumes in pods no longer require git 1.8.5 or newer, older git versions are supported too now. ([#62394](https://github.com/kubernetes/kubernetes/pull/62394), [@jsafrane](https://github.com/jsafrane))

`--oidc-required-claim=<claim>=<value>` Previously, there was no mechanism for a user to specify claims in the OIDC authentication process that were requid to be present in the ID Token with an expected value. This version now makes it possible to require claims support for the OIDC authentication. It allows users to pass in a `--oidc-required-claims` flag, and `key=value` pairs in the API config, which will ensure that the specified required claims are checked against the ID Token claims.
