- Added a path `/header?key=` to `agnhost netexec` allowing one to view what the header value is of the incoming request.

  Ex:
  ```
  $ curl -H "X-Forwarded-For: something" 172.17.0.2:8080/header?key=X-Forwarded-For
  something
  ```
   ([#107796](https://github.com/kubernetes/kubernetes/pull/107796), [@alexanderConstantinescu](https://github.com/alexanderConstantinescu))

 *  New: Support for `TLS_FALLBACK_SCSV`.
 *  New: Update HTTP/2 support to `h2-16` and `hpack-10`.
 *  New: APIs to prevent retrying non-idempotent requests.
 *  Fix: Drop NPN support. Going forward we support ALPN only.
 *  Fix: The hostname verifier is now strict. This is consistent with the hostname
    verifier in modern browsers.
 *  Fix: Improve `CONNECT` handling for misbehaving HTTP proxies.

- Revised error handling for port forwards to Pods. Added stream resets preventing port-forward from blockage. ([#128681](https://github.com/kubernetes/kubernetes/pull/128681), [@soltysh](https://github.com/soltysh)) [SIG API Machinery, CLI and Testing]

It used custom types in its declarations instead of standard Python types, but it was still a huge step forward.

It also was one of the first frameworks to generate a custom schema declaring the whole API in JSON.

- Kubeadm now forwards the IPv6DualStack feature gate using the kubelet component config, instead of the kubelet command line ([#90840](https://github.com/kubernetes/kubernetes/pull/90840), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]

- Added a new CLI flag `--emulation-forward-compatible`
  Added a new CLI `--runtime-config-emulation-forward-compatible` ([#130354](https://github.com/kubernetes/kubernetes/pull/130354), [@siyuanfoundation](https://github.com/siyuanfoundation)) [SIG API Machinery, Etcd and Testing]
