## [Unreleased]

## [0.3.0] - 2023-07-12

Many breaking change here, since last release

### Fixed

- Connecting to WiNet-S with newer firmware which requires the authenticated `login` event to be sent to WebSocket

### Changed

- Default MQTT client ID is now `modbus-mqtt-<rand>` instead of static `modbus-mqtt` to allow multiple instances to run.
- Register values sent directly to register topic, not under `state` sub-topic
- Modbus connection status sent directly to connection topic, not under `state` sub-topic

### Deprecated

- `holding` and `input` sections are no longer separate sections, in favour of specifying `register_type` field on the
  register definition to either `"input"` (default) or `"holding"`.
