dump1090-fa (3.7.1~dev) UNRELEASED; urgency=medium
* in development
-- Eric Tran <eric.tran@flightaware.com> Mon, 15 Apr 2019 11:23:00 -6000
dump1090-fa (3.7.0.1) stable; urgency=medium
* dump1090: Fix piaware lat/lon variable
-- Eric Tran <eric.tran@flightaware.com> Fri, 29 Mar 2019 7:04:00 -6000
dump1090-fa (3.7.0) stable; urgency=medium
* dump1090: Fix Rc decoding errors
* dump1090: Compute ADS-B v0 NACp/SIL
* dump1090: When generating aircraft.json, leave space for the final line;
otherwise the generated json may have trailing garbage
* dump1090: Don't update the known-address-set from DF18 messages
* Skyview: use heading data for icon orientation if track data is unavailable
* Skyview: don't spin forever if there's no history to load / receiver.json
is missing
* dump1090: Bail out if rtlsdr_read_async() returns early; it probably means we lost
the USB device. There was a workaround for this (originally implemented
in dump1090-mutability) that got lost in the refactoring needed to support
different SDRs. librtlsdr can still be flaky under disconnect conditions, so
this won't catch everything.
* dump1090: add ENABLED to /etc/default/dump1090-fa
* dump1090: track FMS and MCP selected altitudes separately
* skyview: use whichever selected altitude is available
* faup1090: updates to support PiAware 3.7.0
-- Oliver Jowett <oliver@mutability.co.uk> Fri, 22 Mar 2019 15:58:04 +0000
dump1090-fa (3.6.3) stable; urgency=medium
* Fix port 30003 output (Basestation) timestamp formatting broken in 3.6.0
