Users of the `btrfs` storage driver on CentOS +are recommended to migrate to a different storage driver, such as `overlay2`, which +is now the default storage driver. Docker 23.0 continues to provide the `btrfs` +storage driver to allow users to migrate to an alternative driver. The next release +of Docker will no longer provide this driver. + ### Support for encrypted TLS private keys **Deprecated in Release: v20.10**
