-You can't just add CCs to a bug by using the C<@cc> parameter like you
-can when you're filing a bug. To add CCs, you can specify them in a
-comma-separated list in C<@newcc>.
+To add CCs, you can specify them in a comma-separated list in C<@cc>.
+For backward compatibility, C<@newcc> can also be used. If both are
+present, C<@cc> takes precedence.
 
 To remove CCs, specify them as a comma-separated list in C<@removecc>.
