+### changes
+
+ - Removed the `-A` flag. Now Kubeshark targets all namespaces by default. Use `-n` flag to specify namespaces.
+ - Changed the `storagelimit` option's format from `200MB` to `200Mi` for complying with Kubernetes' internal quantity parser.
+ - Added a `PersistentVolumeClaim` that the worker DaemonSet mounts.
+ - Added `storageclass` option to set the `StorageClass` in `PersistentVolumeClaim`. Default value is `standard`.
+ - Run `kubeshark config -r` to regenerate the `~/.kubeshark/config.yaml`.
