 ## Features
 * OOP based management of Servers, Storages and IP-addresses with full CRUD.
+	* since 0.2: manage both IPv4 and IPv6 addresses
+	* since 0.1.1: can use custom storage templates in addition to public templates
 * Clear way to define your infrastructure, emphasis on clear and easy syntax
 * Access all the data of the objects ( e.g. ssh credentials )
 * Scale horizontally by creating / destroying servers
 * Scale vertically by changing the RAM, CPU, storage specs of any server
+* Manage firewall (on/off and individual rules)
+	* since 0.2: full management of firewall rules

-* Full management of Firewall rules (per server on/off supported at the moment)
-  * defining a server's L2 firewall's rules through the API client
+  * (custom templates can already be cloned to a disk via UUID)
