[release] ChirpStack Application Server v3.8 (test releases)

ChirpStack Application Server v3.8.0-test.1


New error events

This release provide new error events for OTAA errors, frame-counter resets and re-transactions / replay-attacks (requires ChirpStack Network Server v3.7+). It also adds new error events when the gateway reports an error on downlink scheduling (e.g. collision, invalid frequency, …).

Downlink tx ack event

This publishes an acknowledgement when an item from the queue has been sent to the gateway for transmission and was accepted by the gateway.

myDevices integration

This new integration makes it possible to forward payload events to myDevices Cayenne and IoT in a Box.

Syslog logger

This adds a configuration option log_to_syslog. When enabled, log items will be forwarded to syslog.
