 Notable changes:
 
 * Added a new I/O module `rbdaio` which uses the asynchronous API of `librbd`.  Performance results in relation to `rbd`
-  have been mixed but performance should at least be 10-20% bigger.  In one case performance has been increased tenfold.

+  increased tenfold.
 
 * Almost all Bash helper scripts have been rewritten in Python. The new scripts are calling Benji via the command line
-  just like before. This is intentional to minimize the interdependence between Benji and these helpers. These
+  just like before. This is intentional to minimize the interdependence between Benji and these helpers. The
   scripts are examples only and not part of the API. There still is one example Bash script at `scripts/ceph.sh` to show
   how to interact with Benji via Bash. The helpers have additional dependencies which can be installed with
   `pip install benji[helpers]`.
 
 * The Prometheus metrics exported by `benji-k8s` have changed:
 
     * Backup metrics now longer include the `auxiliary_data` label.
-    * Command metrics now longer include the `arguments` label. The
-      arguments have been folded into the `command` label.

 * `benji-k8s`: The included scripts have been replaced by Python scripts and are using the new helper modules. They 
   should be calling compatible.
 
 * `benji-k8s`: All calls to `kubectl` have been replaced with direct API requests. The official Python client for
-  Kubernetes is used.

+  Kubernetes is used. `kubectl` is still included in the image.
 
 * Helm chart: Volumes and volume mounts are now configurable via `values.yaml`. This is mostly for getting the Ceph
   credentials into the container but could also be used to mount file-based storage.

+* Helm chart: The PostgreSQL chart dependency was updated from 2.7.6 to 4.2.2. This is the last chart which uses 
   PostgreSQL 10 and requires no upgrade of the database data structures.
 
 * `benji-k8s` and Helm chart: The image was simplified to only include the Kubernetes specific scripts and `kubectl`.
