[release] ChirpStack Concentratord v4.2

Announcements
1

v4.2.0

Features

Refactor model configuration

This release adds a region configuration option and removes the region suffix from the gateway / shield model. This changes the configuration from:

model="rak_rak2247_eu868"

to:

model="rak_rak2247"
region="EU868"

For backwards compatibility, the old model configuration remains valid in this version, but will be removed in v4.3.0.

Other features

  • Add CN470 support for semtech_sx1302c490gw1 shield.
  • Add AU915 support for sandbox_lorago_port shield.
  • Add fine-timestamp for SX1302/SX1302. (#66)

Improvements

Build improvements

The provided pre-compiled binaries are fully static and based on musl libc. This removes the need to compile against a very old verion of glibc to stay compatible with old gateway firmwares.

Other improvements

  • Update internal dependencies.
  • Implement time fallback option in case no GPS time-source is available. (#49)

Bugfixes

  • Fix Class-B beacon channel-hopping.
  • Fix typo in 2g4 logs (it would log under the chirpstack-concentratord-sx1301 process name).
