v4.0.0

This is the first release of lib1090 after its fork from java-adsb. The library has undergone a lot of refactoring and cleanup. Despite of all the breaking changes, moving from java-adsb version 3.X to lib1090 should not be a large effort.

We have decided to keep the version numbering of the original project. Due to the breaking API changes, we are happy to release our first version of the library as v4.0.0.

Please find an overview of all the changes below.

Breaking Changes

  • Restructured Java packages
  • Renamed ModeSReply to ModeSDownlinkMsg
  • Introduced QualifiedAddress as aircraft identifier to replace ICAO 24 bit address. This allows different types of targets as required by ADS-R/TIS-B.
  • Renamed ModeSDecoder to StatefulModeSDecoder
  • Providing a timestamp is now mandatory when decoding messages
  • Changed return value of nearly all toString() methods
  • Renamed getHeading() method to getTrueTrackAngle() in VelocityOverGroundMsg
  • Cleaner semantics for isAirborne()/isOnGround() status in AllCallReply, AltitudeReply, CommBAltitudeReply IdentifyReply and CommBIdentifyReply
  • Removed deprecated Decoder class

New Features

  • Added ADS-R and TIS-B decoding
  • Added decoders for various BDS registers (10, 17, 20, 30, 40, 50, 60)
  • Added hasAlert() and hasSPI() methods to AirbornePositionMsg
  • Allow custom logic for position decoding
  • Introduced altitude type to Position (barometric, above ground, ...)

Bug Fixes

  • Fixed longitude bug for surface position messages
  • Fixed NIC values for MOPS v0 Airborne Positions

Misc Changes

  • Removed logging and slf4j dependency
