Flight Gear version 0.57 is now available.

The Flight Gear Flight Simulator project is a free, open-source,
multi-platform flight sim development project. Source code for the
entire project is available and licensed under the GPL.

New in Version 0.57:

  • Converted to a simpler frame rate counting method.
  • Fixed the AOA reading on the HUD.
  • Removed gpc from the Lib section of distribution by request of
    the gpc Author. The gpc license is unfortunately not compatible
    with the GPL. I may look for an alternative library, or just
    require that developers download this library separately.
  • First slew of changes from the MacOS porting effort contributed
    by “Robert Puyol” <[email protected]>.
  • Support for an arbitrary number of serial ports + additional
    serial port output tweaks.
  • Serial output tweaks to make things more robust and act more
    like a GPS.
  • Portability enhancements for Borland, Solaris, and SGI.
  • Some internal class renaming and reorganizations. fgFLIGHT
    becomes FGState. fgCONTROLS becomes FGControls.
  • Started work on an “external” flight model so the sim can be
    driven from external input (serial port, network, file, etc.)
  • Fixed a problem that creeped in with setting the initial
    startup altitude. This could cause an unrecoverable bounce and
    you’d end up flipped on your back. Should be fixed now.
  • Sun now appears to grow in size as it gets very low in the
    horizon.
  • Fixed a view frustum culling bug where the scene was not
    accurately culled when your view was anything other than straight
    forward.
