Mark release, point to change log

This makes the driver version with future versions of molecule,
which will no longer have the cache in them. Same kind of change
was already merged in two other drivers podman and docker.

+## Network Creation
+
+This Driver is able to generate networks and subnetworks during the test run.
+This can be useful for cluster tests. You can create networks with the
+following snippet:
+
+```yaml
+platforms:
+  - name: instance1
+    server_type: cx11
+    image: debian-10
+    networks:
+      test-network:
+        ip_range: 10.10.0.0/16
+        subnet:
+          ip: 10.10.10.1/24
+          type: cloud
+          network_zone: eu-central
+      test-network-2:
+        ip_range: 10.20.0.0/16
+        subnet:
+          ip: 10.20.10.1/24
+  - name: instance2
+    server_type: cx11
+    image: debian-10
+    networks:
+      test-network:
+        subnet:
+          ip: 10.10.10.2/24
+```
+
+The networks **ip_range** is only important for creating. If you have multiple
+hosts, it is okay to only define **ip_range** once. The supported keys are:
+
+- **networks**
+    - **ip_range** (required): ip range of network (usually `/16`)
+
