- If a bad flag is supplied to a kubectl command, only a tip to run `--help` is printed, instead of the usage menu.  Usage menu is printed upon running `kubectl command --help`. ([#82423](https://github.com/kubernetes/kubernetes/pull/82423), [@sallyom](https://github.com/sallyom))

- In text format, log messages that previously used quoting to prevent multi-line output (for example, text="some \"quotation\", a\nline break") will now be printed with more readable multi-line output without the escape sequences. ([#107103](https://github.com/kubernetes/kubernetes/pull/107103), [@pohly](https://github.com/pohly))

- kubectl now loads config file once and uses persistent client config ([#71117](https://github.com/kubernetes/kubernetes/pull/71117), [@dixudx](https://github.com/dixudx))
- Printed `SizeLimit` of `EmptyDir` in `kubectl describe pod` outputs. ([#69279](https://github.com/kubernetes/kubernetes/pull/69279), [@dtaniwaki](https://github.com/dtaniwaki))

cluster admin can then decide to keep the file present on a node host or move it to a safe location. `kubadm certs renew` will renew the certificate in `super-admin.conf` to one year if the file exists; if it does not exist a "MISSING" note will be printed. `kubeadm upgrade apply` for this release will migrate this particular node to the two file setup. Subsequent kubeadm releases will continue to optionally renew the certificate in `super-admin.conf` if the file exists on disk and if renew on upgrade...

- Error message for Pods with requests exceeding limits will have a limit value printed. ([#112925](https://github.com/kubernetes/kubernetes/pull/112925), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev))
