- Kubectl: The deprecated `kubectl alpha debug` command is removed. Use `kubectl debug` instead. ([#98111](https://github.com/kubernetes/kubernetes/pull/98111), [@pandaamanda](https://github.com/pandaamanda)) [SIG CLI]

- Added "general", "baseline", and "restricted" debugging profiles for kubectl debug. ([#114280](https://github.com/kubernetes/kubernetes/pull/114280), [@sding3](https://github.com/sding3)) [SIG CLI]
- Added "netadmin" debugging profiles for kubectl debug. ([#115712](https://github.com/kubernetes/kubernetes/pull/115712), [@wedaly](https://github.com/wedaly)) [SIG CLI]

Users who create ephemeral containers using `kubectl debug` should note that kubectl version 1.22 will attempt to fall back to the old API; older versions of kubectl will not work with cluster versions of 1.22 or later. Please update kubectl to 1.22 if you wish to use `kubectl debug` with a mix of cluster versions.

## Known Issues

In previous versions of Python, you could have used threads or <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>. But the code is way more complex to understand, debug, and think about.

In previous versions of NodeJS / Browser JavaScript, you would have used "callbacks". Which leads to "callback hell".

## Coroutines { #coroutines }

- `kubectl alpha debug` command now supports debugging pods by copy the original one. ([#90094](https://github.com/kubernetes/kubernetes/pull/90094), [@aylei](https://github.com/aylei)) [SIG CLI]

* Exposed `/debug/flags/v` to allow dynamically set glog logging level.  For example, to change glog level to 3, send a PUT request such as `curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3"`. ([#63777](https://github.com/kubernetes/kubernetes/pull/63777), [@hzxuzhonghu](https://github.com/hzxuzhonghu))

- Added validation of `containerLogMaxFiles` within kubelet configuration files. ([#129072](https://github.com/kubernetes/kubernetes/pull/129072), [@kannon92](https://github.com/kannon92))
- Adding resource completion in kubectl debug command ([#130033](https://github.com/kubernetes/kubernetes/pull/130033), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI]

- The apiserver debug endpoint `/debug/api_priority_and_fairness/dump_requests` has been extended to dump executing requests as well as queued ones.  A column for StartTime has been added to the returned table, with the queued requests having a StartTime of "0001-01-01T00:00:00Z"....
