Unreleased

Added

Deprecated

Fixed

Security

3.4.2 (2020-01-08)

Added

  • Forwarding of backend warnings to the Console.
  • Auth Info service to the JavaScript SDK.
  • Subscribable events to the JavaScript SDK.
  • Include gateway_ID field in Semtech UDP configuration response from Gateway Configuration Server.

Changed

  • Increase time that class C messages are scheduled in advance from 300 to 500 ms to support higher latency gateway backhauls.

Fixed

  • Fix selection of pseudo wildcard rights being possible (leading to crash) in the Console even when such right cannot be granted.
  • Fix loading spinner being stuck infinitely in gateway / application / organization overview when some rights aren't granted to the collaborator.
  • Fix deadlock of application add form in the Console when the submit results in an error.
  • Fix ttn-lw-cli sometimes refusing to update Gateway EUI.

3.4.1 (2019-12-30)

Added

  • Support for ordering in List RPCs.
  • Detect existing Basic Station time epoch when the gateway was already running long before it (re)connected to the Gateway Server.

Changed

  • Reduce the downlink path expiry window to 15 seconds, i.e. typically missing three PULL_DATA frames.
  • Reduce the connection expiry window to 1 minute.
  • Reduce default UDP address block time from 5 minutes to 1 minute. This allows for faster reconnecting if the gateway changes IP address. The downlink path and connection now expire before the UDP source address is released.

Fixed

  • Fix class A downlink scheduling when an uplink message has been received between the triggering uplink message.

3.4.0 (2019-12-24)

Added

  • Downlink queue operation topics in the PubSub integrations can now be configured using the Console.
  • List RPC in the user registry and related messages.
  • User management for admins in the Console.
  • users list command in the CLI.
  • Support for getting Kerlink CPF configurations from Gateway Configuration Server.
  • Support for Microchip ATECC608A-TNGLORA-C manifest files in device template conversion.

Fixed

  • Fix the PubSub integration edit page in the Console.
  • Fix updating and setting of webhook headers in the Console.
  • Fix DevNonce checks for LoRaWAN 1.0.3.

3.3.2 (2019-12-04)

Added

  • Support for selecting gateways when queueing downlinks via CLI (see class-b-c.gateways option).
  • Options is.oauth.ui.branding-base-url and console.ui.branding-base-url that can be used to customize the branding (logos) of the web UI.
  • Email templates can now also be loaded from blob buckets.
  • Support for pagination in search APIs.
  • Search is now also available to non-admin users.
  • Support for searching end devices within an application.
  • Notification during login informing users of unapproved user accounts.
  • Support maximum EIRP value from frequency plans sub-bands.
  • Support duty-cycle value from frequency plans sub-bands.

Changed

  • Allow enqueuing class B/C downlinks regardless of active device class.

Fixed

  • Fix crashing of organization collaborator edit page.
  • Avoid validating existing queue on application downlink pushes.
  • Correct AU_915_928 maximum EIRP value to 30 dBm in 915.0 – 928.0 MHz (was 16.15 dBm).
  • Correct US_902_928 maximum EIRP value to 23.15 dBm in 902.3 – 914.9 MHz (was 32.15 dBm) and 28.15 dBm in 923.3 – 927.5 MHz (was 32.15 dBm). This aligns with US915 Hybrid Mode.
  • Correct AS_923 maximum EIRP value to 16 dBm in 923.0 – 923.5 MHz (was 16.15 dBm).

Security

  • Keep session keys separate by JoinEUI to avoid conditions where session keys are retrieved only by DevEUI and the session key identifier. This breaks retrieving session keys of devices that have been activated on a deployment running a previous version. Since the Application Server instances are currently in-cluster, there is no need for an Application Server to retrieve the AppSKey from the Join Server, making this breaking change ineffective.

  • The Network Server now provides the timestamp at which it received join-accept or data uplink messages.
  • Add more details to logs that contain errors.
  • Support for end device pictures in the Identity Server.
