# Bayou Radar Skywarn 0.2.0 Release Notes

Bayou Radar Skywarn now uses Bayou Radar as its primary alert service and keeps the direct National Weather Service API as an automatic resilience path.

## Data flow

- Normal operation: node → `backend.bayouradar.com` → Bayou Radar alert response.
- Primary failure for one area: node → direct NWS API for that area only.
- Both sources unavailable: retain unexpired cached alerts for that area.
- Valid Bayou Radar response with zero alerts: accept it and do not contact NWS.

The dashboard clearly identifies Bayou Radar, NWS fallback, or unavailable status for every monitored area.

## Configuration change

New installations define monitored areas in the top-level `areas` list. Each area requires a UGC code and should contain a Bayou Radar bounding box or point. Existing configurations using `nws.areas` remain readable, but areas without Bayou Radar coordinates will operate through NWS fallback until a point or bounding box is added.

## Qualification

The release includes mocked primary/fallback tests and all existing alert, cache, audio, state, and disabled-mode tests. A real repeater qualification should still confirm local Asterisk permissions, playback level, transmitter key-up delay, and the chosen area boundaries before production use.
