Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[0.90.2] - 2022-07-04

Added

  • Introduce the DeviceOptions struct to expose all possible configuration options for the device.
  • Add NewDeviceWithPersistency as default constructor.
  • Add a NewDeviceWithOptions constructor to allow device configurations different from the default one.
  • Allow the device to send purge properties messages.

Changed

  • Deprecate the NewDevice constructor. NewDevice will be removed in the next version.
  • Allow to use a db different from SQLite for persistency. CGO is now optional, if SQLite is not used.
  • Use ECDSA instead of RSA private keys.
  • AddInterface does no more perform validation, as this is already done by astarte-go. The return value of AddInterface is always nil.
  • Update Go to v1.17.

Fixed

  • Do not send data before all Astarte MQTTv1 initialisation messages have been sent, fixing a race condition which sometimes resulted in device disconnection.

[0.90.1] - 2022-02-14

Added

  • Allow to ignore client-side SSL errors with the Device.IgnoreSSLErrors field. Defaults to false.
  • Add messages (when retention: stored) and properties persistency. This requires a SQLite db and compiling with CGO.
  • Add SetProperty and UnsetProperty methods for setting and unsetting properties on device side.
  • Add GetProperty, GetAllPropertiesForInterface and GetAllProperties methods for retrieving properties.
  • Handle reception of purge properties messages from Astarte.

Changed

  • Do not redo all initialisation steps of Astarte MQTTv1 protocol at each device reconnection, but only if there is no session present on the broker.
  • Send properties only if their value has changed.
  • Replace eclipse/paho.mqtt.golang dep with ispirata/paho.mqtt.golang, which handles the sessionPresent MQTT flag correctly.
  • Deprecate SendIndividualMessageWithTimestamp and SendIndividualMessage methods for sending properties.

Fixed

  • Do not to panic when checking certificate validity.

[0.90.0] - 2021-08-17

Added

  • First Astarte Device SDK Go release.
