+### Hooks plugin
+
+* Username parameters are added to hook invocations.
+
+ When an account parameter is passed to a hook, it gets formatted as
+ `Name (Email)` or just `Name` when the account does not have an email
+ address. If the account's name is not set, the name is "Anonymous
+ Coward". From this information it is not easy for a hook to get the
+ account's username.
+
+ All hooks that take an account parameter now automatically also get a
+ corresponding username parameter. For example if the hooks takes the
+ parameter `--change-owner Name (Email)` it will automatically also get
+ the parameter `--change-owner-username username`
