3.12.0

Added

  • API and CLI commands for listing, searching for and restoring recently deleted applications, OAuth clients, gateways, organizations and users.
  • State Description fields for adding context to the (rejected, flagged, suspended) state of Users, OAuth clients and tenants.
    • This requires a database schema migration (ttn-lw-stack is-db migrate) because of the added columns.
  • Configure retention policy for the Storage Integration database (only supported when using TimescaleDB).
    • You will need to run the ttn-lw-stack storage-db migrate command to apply the new configuration. See the --timescaledb.chunk-time-interval, --timescaledb.enable-retention-policy and --timescaledb.retention-days command-line flags.
  • Searching for gateways by EUI.
  • Searching for users and OAuth clients by state.
  • Gateway Server forwards Tx Acknowlegdment packets to the Network Server for scheduled downlinks. These can be used by the Network Server to forward downlink_ack upstream messages to the Application Server.
  • UDP connection error caching. The duration can be configured via the gs.udp.connection-error-expires configuration entry.
  • Option to require individual gateways to use authenticated connections.
    • This requires a database schema migration (ttn-lw-stack is-db migrate) because of the added columns.
  • Login Tokens (magic login links) that can be used for password-less login.
    • This requires a database schema migration (ttn-lw-stack is-db migrate) because of the added columns.
    • This feature is disabled by default; use the new is.login-tokens.enabled option to enable it.
  • Packet Broker registration, configuration of routing policies, listing home networks and viewing routing policies set by forwarding networks. See ttn-lw-cli packetbroker --help for more information.
  • Support LoRa 2.4 GHz with Packet Broker.
  • Include gateway identifiers from Packet Broker in metadata.
  • Support for claiming gateways through CLI. See ttn-lw-cli gateways claim --help for more information.
  • Session and MAC state import functionality. This means that devices can be migrated without rejoin.
  • Rate limiting for HTTP endpoints, gRPC endpoints, MQTT, UDP and WebSockets connections.
    • Rate limiting is disabled by default. Refer to the rate-limiting configuration entry to enable.
  • Profile settings link to header dropdown menu.

Changed

  • Changed the pub/sub channels that the Redis backend of the Events system uses.
  • Changed the encoding of events transported by the Redis backend of the Events system.
  • All external HTTP calls are now using TLS client configuration. This fixes issues where HTTP calls would fail if custom (e.g. self-signed) CAs were used.
  • All external HTTP calls are now using a default timeout. This fixes issues where HTTP calls would stall for a long time.
  • All value wrappers now are encoded and decoded as the value being wrapped in JSON. That means, that, e.g. format of mac_settings.rx1_delay is changed from {"value": 2} to just 2.
  • Changed the error that is returned when attempting to validate already validated contact info.
    • This requires a database schema migration (ttn-lw-stack is-db migrate) because of the added column.
  • Update Go to 1.16
  • Network Server now performs more strict validation and will disallow creation and updates of invalid devices.
  • DevEUI is not required for multicast devices anymore, regarding of LoRaWAN version.
  • Pub/Sub provider visibility in console based on disabled status.

Removed

  • AWS IoT Integration as pub/sub integration. The integration is only available as application package.
    • This requires a database migration (ttn-lw-stack as-db migrate).

Fixed

  • Incorrect documentation url for event details data formats.
  • Search functionality for applications, gateways and organizations in the Console.
  • Error handling of end device template formats for the application overview page in the Console.
  • Payload size limits for AU915 data rates 8 and 9, which are now consistent with Regional Parameters RP002-1.0.2.
  • Payload size limit calculation in Network Server.
  • Occasional panic in Network Server on downlink with corrupted device states.
  • Occasional panic in Identity Server on extracting log fields from invalid requests.
  • Print an error message stating that the Storage Integration is not available in the open source edition of The Things Stack when trying to execute ttn-lw-stack storage-db commands.
  • Applications without AWS IoT integration displaying configuration of a previously inspected application.
