Bump dependencies?
This release sees a cleaning of Tokio ZMQ's dependencies. It now relies on sub-crates of Futures and of Tokio, so it doesn't pull more than it needs to. I also bumped tokio-file-unix, which recently released full tokio-support, so it doesn't pull tokio-core anymore.
There will probably be another beta release before 0.4 hits. I'm waiting on tokio to fully adopt futures2 support, so I can drop my own fork of tokio-timer. And since I messed up the versioning for tokio-zmq-derive already, the first version of 0.4 might be 0.4.1 or 0.4.2. We'll just have to see.
