v4.16.0

Features

RP002-1.0.5 support

This adds support for RP002-1.0.5 support, which includes support for LoRa SF5 and SF6. This also refactors how the min / max data-rate range works internally. This is required as with RP002-1.0.5 the semantics of min / max data-rates has changed and is no longer guaranteed to be a range. Please refer to the RP002-1.0.5 specs for more information.

As devices supporting RP002-1.0.5 are not required to implement all data-rates, ChirpStack assumes the device only supports the mandatory data-rates, unless otherwise configured in the device-profile.

DNS-based join-server resolving

This release adds DNS-based join-server resolving, based on the JoinEUI from the join-request.

Device-profile refactor

This change refactors the device-profile templates into the device profiles. Device profiles can now be global (and used by multiple tenants) and / or managed per-tenant (when the device profiles can only be used by the given tenant). This way, it is no longer needed to copy a device-profile template into a device profile. It also means that changes to a global device profile immediately propagate to the devices using the change device profile.

This change replaces the import-legacy-lorawan-devices-repository device profile import command by import-device-profiles, which import device profiles from https://github.com/chirpstack/chirpstack-device-profiles. Vendors and ChirpStack-users are encouraged to add their devices / devices they are using to this repository.

Note: Migrating existing device-profile templates to global device profiles can be performed using the migrate-device-profile-templates sub-command, e.g.:

chirpstack -c /path/to/config migrate-device-profile-templates
