## 2.3.0
- Indicate compatibility with `package:web_socket_channel` 2.x and 3.x.
- Bump minimum version for `package:unified_analytics` to 6.1.0.
- `DartToolingDaemon.connect` will now wait for the web socket to be connected.
- The `DartToolingDaemon` constructor is now public and can be directly called
  with a `StreamChannel<String>`.
- The `params` parameter in `DartToolingDaemon.call()` has been changed from
  `Map<String, Object>?` to `Map<String, Object?>?`.
- `registerService` now allows passing a `Map<String, Object?>? capabilities`
  that can be supplied to clients via new `ServiceRegistered` and
  `ServiceUregistered` events on the `Service` stream (when connected to a
  version of DTD that supports these streams).
- Calling `DartToolingDaemon.onEvent()` now returns a broadcast stream. This
  means multiple listeners can be added, but also means you must add a listener
  prior to calling `streamListen` to avoid the possibility of missing events.
