## v1.9.0 - 2023-12-11
### Added
- Parse objectJSON string to JSON object, allowing usage of items in it. Thus, the modbus server can be used with the "new" chirpstack JSON marshaller

### Fixed
- Keep restarting modbus server by increasing the time between restart attempts, and not trigger the start limit watchdog

## v1.8.2 - 2023-12-01
### Changed
- Restart modbus server if connection to serial port is lost, instead of terminating the service.
- Ensure systemd always tries to restart the server (unless stopped by systemctl), but delay successive restarts up to 10s.

### Fixed
- Return errcode (1) if the server exits due to an error in a service (e.g. Modbus service loses connection to its serial port).

## v1.8.1 - 2023-11-13
### Added
- Method for safely setting and getting LoRaWAN activations map, via its mutex
- Tests for LoRaWAN activations: JSON export, setting, getting

### Changed
- Set and Get LoRaWAN activations map via its method, to avoid concurrent writes or iterations
  - Was possible when Store was saved while Activations were updated

## v1.8.0 - 2023-05-24
### Added
- Variable downlinks via Modbus
  - Set trigger register and (max) downlink length Len in modbus registers (16 bits/2 bytes each)
  - Write downlink content to registers behind trigger register (max Len registers)
  - Write `<port><length>` in hex to trigger register to send downlink
    - E.g. write `8009`(hex) to trigger register to send 4 + first half of 5th register following it (=9 bytes) as a downlink to port 128 of the device

### Changed
- Set downlink (trigger) register to `0` instead of `1`
- Use modbus slaveID from config file
- Default modbus slaveID to `1`
- Upgrade go dependencies

## v1.7.0 - 2023-05-11
### Added
- Chirpstack API calls via gRPC for future use

### Changed
- Update go dependencies
  - Update jwt usage, fix token parser test

### Deprecated
- Chirpstack service Profile no longer used for gateway creation

## v1.6.1 - 2023-05-04
### Changed
- No storage of downlink registers in `register-map.json`
  - Avoids issues with former downlink registers not losing their state after a config change

### Fixed
- Bug where device uplinks would be missed because of MQTT legacy topic subscription

## v1.6.0 2023-04-17
### Added
- Add local gateway via REST to Chirpstack, determining gateway EUI from packet forwarder config.

## v1.5.0 - 2023-04-04
### Added
- Downlinks triggered by modbus register writes
  - Value in register will be written value if last downlink was successful, 0xFFFF if last downlink failed

### Fixed
- Bug where 32-bit values wouldn't be stored properly in modbus registers

## v1.4.1 - 2022-09-01
### Fixed
- Bug where devices are not created in Chirpstack

## v1.4.0 - 2022-08-31
### Added
- Gateway Userinterface on port 8081

## v1.3.1 - 2022-06-28

### Fixed
- Handling of verbose flag
- verbose logging for config loading

## v1.3.0 - 2021-02-01

### Added
- Device activations are saved and restored

### Changed
- Setup sets 777 access rights on config file and dir

## 1.2.1

### Added
- devName config parameter to specify an optional device name

### Fixed
- modbus "disabled" config parameter was always true

## 1.2.0

### Added
- Allow to configure modbus serial connection parameters
  - modbus.dataBits: 8
  - modbus.parity: "even" # no, even (default), odd
  - modbus.stopBits: 1 # 1 (default), 1.5, 2

## 1.1.1

### Added
- Support int32, uint32, float32 register types

### Fixed
- Bug where register data is not saved

## 1.0.7

### Fixed

- Allow async access on modbus registers. Might solve invalid value read-out. 
- Persist data only once per minute
- Persist data on exit

## 1.0.6

### Fixed

- Reconnect to MQTT on disconnect
- possible endless loop on MQTT receive

## 1.0.3

### Fixed
- modbus register readout (was always 0)
