- Fixes a regression exposed in 1.27 by kubectl switching to openapi v3 by making apiregistration.k8s.io discoverable in openapi/v3 ([#119841](https://github.com/kubernetes/kubernetes/pull/119841), [@atiratree](https://github.com/atiratree)) [SIG API Machinery]

- Renames the timeout field for the DelegatingAuthenticationOptions to TokenRequestTimeout and set the timeout only for the token review client. Previously the timeout was also applied to watches making them reconnecting every 10 seconds.

* Filter published OpenAPI schema by making nullable, required fields non-required in order to avoid kubectl to wrongly reject null values. ([#85733](https://github.com/kubernetes/kubernetes/pull/85733), [@sttts](https://github.com/sttts))

- Modified command line errors (for example, `kubectl list` -> `unknown command`) that were printed as log message with escaped line breaks instead of a multi-line plain text, making the error hard to read.
