Wouldn't it be better to mark each of them with appropriate version? 
I have to had to draw the method diagrams for versions to understand their appurtenance:
3.2.x:
* `getFlow` +
* `flow` +
* `flowBlocked` -
* `basicConsume` with `Map` -
* `basicQos` with `global` -

3.3.x
* `getFlow` -
* `flow` -
* `flowBlocked` +
* `basicConsume` with `Map` +
* `basicQos` with `global` +
