Until now 'send' is synonym for 'resume' and 'receive' is synonym for 'suspend'. This is confusing, at least, as 'suspend' will yield a message sent earlier. Now 'send'/'resume' are asynchronous way to exchange messages and 'suspend'/'resume' are synchronous way to exchange messages. See updated documentation for details.
