  • Moved to a simpler versioning scheme rather than trying
    to put suffixes on the end of the upstream version scheme.
  • Statistics updates for the stats junkies amongst us.
    Note that many of these apply to the 2.4MHz demodulator only.
    • Rationalized the demodulation stats that are collected.
    • Collect mean signal level, peak signal values.
    • Collect a count of signals stronger than -3dBFS.
    • Collect stats on remotely-received messages.
    • Collect stats on CPR position decoding.
    • Collect more CPU stats.
    • Stat buckets for the last 1, 5, 15 mins are maintained.
    • Stats display due to --stats-every does not reset the "total" stats.
    • All stats are now exported via JSON at /data/stats.json.
  • When --oversample --phase-enhance is in use, all phase positions are
    evaluated and the best result is used, rather than stopping at the first
    error-free message. This increases CPU by about 1/4 but recovers about
    5% more messages.
  • Error correction in --aggressive mode is now more conservative:
    it will only fix 2-bit errors that can't be confused with a 4-bit error.
  • DF11 messages can now be partially error-corrected (only for errors that
    do not result in a syndrome in the final 7 CRC bits)
  • Partial TIS-B support. Feedback sought from people who actually receive
    TIS-B messages!
  • Support for non-alphanumeric characters in callsigns.
  • RSSI measured for individual messages.
  • Simple filtering for bogus messages that make it past CRC checks: don't
    display or emit aircraft state until we have seen at least two messages
    from the same aircraft.
  • --net-verbatim option added; if enabled, for messages that have
    repairable CRC errors the unrepaired version of the message is forwarded
    to network clients. This lets the client decide what policy to impose on
    damaged messages.
  • Made 2.4MHz sampling the default for new installs.
  • Internal changes:
    • Restructuring of the code to be a bit more modular.
    • Mode S message decoder and output formatting cleanups.
    • 2.4MHz demodulator main loop unrolled to demodulate a byte at a time;
      this helps compensate a little for the --phase-enhance change above.
    • CRC calculation switched to a faster byte-at-a-time table lookup.
    • ICAO address filter rewritten to be a bit smarter, and to support
      Comm-B overlay control in the future.
    • Non-ICAO addresses (e.g. from TIS-B and ModeA/C) are flagged internally
      so they cannot be confused with a real ICAO address.
    • More changes to try to work around libusb crashes on exit.
  • Webmap changes:
    • Show recent RSSI for the selected aircraft.
    • Non-ICAO addresses are shown italicized.
    • Fix webmap stable sort of rows with no sortable values (would cause
      "jumping" rows at the end of the table)
    • Doubleclick on an aircraft marker or table row to follow that aircraft,
      recentering the map as it moves. Or click on the selected aircraft's
      callsign or the arrow next to it.
    • config.js cleanups. Page title and site name can be specified here now.
    • Added vertical rate indicators to altitudes on the webmap.
    • Linked from the aircraft ICAO to airframes.org. (Other site
      recommendations welcome!)
    • Infoblock layout changes.
  • License for my modifications changed to GPL2+. Previous binary
    releases were effectively already GPL2+ due to linking with librtlsdr.
