### `kubectl debug` graduates to Beta

`kubectl alpha debug` graduates from alpha to beta in 1.20, becoming `kubectl debug`.
`kubectl debug` provides support for common debugging workflows directly from kubectl. Troubleshooting scenarios supported in this release of `kubectl` include:

 - Inspect configuration files on a node's host filesystem

- Kubectl: `kubectl get` will omit managed fields by default now. Users could set `--show-managed-fields` to true to show managedFields when the output format is either `json` or `yaml`.

- Added ability for kubectl wait to wait on arbitary JSON path (#105776, @lauchokyip) [SIG CLI]
- Added the ability to specify whether to use an RFC7396 JSON Merge Patch, an RFC6902 JSON Patch, or a Strategic Merge Patch to perform an override of the resources created by kubectl run and kubectl expose. (#105140, @brianpursley) [SIG CLI]
