## Before Upgrading

Consider the following changes, limitations, and guidelines before you upgrade:

* The kubelet now fails if swap is enabled on a node. To override the default and run with /proc/swaps on, set `--fail-swap-on=false`. The experimental flag `--experimental-fail-swap-on` is deprecated in this release, and will be removed in a future release.

- Kubectl: print error if users place flags before plugin name ([#92343](https://github.com/kubernetes/kubernetes/pull/92343), [@knight42](https://github.com/knight42)) [SIG CLI]
- Kubelet: assume that swap is disabled when `/proc/swaps` does not exist ([#93931](https://github.com/kubernetes/kubernetes/pull/93931), [@SataQiu](https://github.com/SataQiu)) [SIG Node]

* Used inline func to ensure unlock is executed ([#61644](https://github.com/kubernetes/kubernetes/pull/61644), [@resouer](https://github.com/resouer))
* kubernetes-master charm now properly clears the client-ca-file setting on the apiserver snap ([#61479](https://github.com/kubernetes/kubernetes/pull/61479), [@hyperbolic2346](https://github.com/hyperbolic2346))
