Lastly, the dialogue management system has been greatly simplified. Just compare the [new `examples/dialogue.rs`](https://github.com/teloxide/teloxide/blob/25f863402d4f377f573ce2ba394f5b768ee8052e/examples/dialogue.rs) with the [old one](https://github.com/teloxide/teloxide/tree/2a6067fe94773a0015627a6aaa1930b8f88b6da0/examples/dialogue_bot/src) to see the difference. Now you don't need `TransitionIn`, `TransitionOut`, `#[teloxide(subtransition)]`, etc. All you need is to derive `DialogueState` for your FSM enumeration, call `.enter_dialogue()` and write handlers for each of a dialogue's states. Instead of supplying dependencies in the `aux` parameter of `Transition::react`, you can just call `.dependencies()` while setting up the dispatcher and all the dependencies will be passed to your handler functions as parameters.

Note that, in one of the upcoming releases, the old dispatching model will be removed, so we highly encourage you to migrate your bots to the new one.
