During this maintenance window we will upgrade The Things Network v3.18.0

We do not expect noticeable downtime during this deployment.

Here is the changelog since the current version v3.17.2:

Added

  • Retain at most 10 recent session keys in the Join Server. This avoids a slowly growing number of session keys in the Join Server's database.
    • This requires a database migration (ttn-lw-stack js-db migrate).
  • Add TTL for gateway connection stats. Can be configured with the option gs.connection-stats-ttl.
  • AWS Cloud Map cluster service discovery support:
    • This method is meant to be used when DNS service discovery is unreliable. This can occur with AWS Route53 if more than 8 instances are available per service.
    • The peer address should contain the service names. Ports may be specified if the service discovery entry does not have a port specified.
    • The --cluster.aws.cloud-map.namespace configuration option can be used to configure the namespace name.
  • Configuration options is.database-max-idle-conns and is.database-max-open-conns to control the database connection pool of the Identity Server.

Changed

  • The minimum required Redis version is now 6.2.

Deprecated

  • Gateway Server setting gs.update-connection-stats-debounce-time is no longer valid.

Fixed

  • Device activation flow with a LoRaWAN Backend Interfaces 1.1 capable Join Server.
    • Join Servers using Backend Interfaces 1.1 (protocol BI1.1) must be configured with a sender-ns-id containing the EUI of the Network Server.
  • Fix time.Duration flags in CLI.
  • Gateway Server will no longer leave permanent gateway connection stats data on the registry when crashing.
