+New in 0.7.3
+* May 18, 2000
+* Added a radio stack 2 VOR/ILS and an ADF to the instrument panel.
+ You can change the frequencies by clicking on the knobs on the
+ instrument panels. You can now navigate with VOR/ADF/DME and fly
+ ILS approaches.
+* Added a chronometer to the instrument panel.
+* Added a "wet" compass to the top of the instrument panel.
+* Compass, vsi, and altitute instruments and vacuum system are more
+ accurately modeled.
+* Added a magnetic variation model.
+* Added navaid database management and query code.
+* Added magvar offset to VOR radials.
+* Heading bug now display magnetic heading rather than true heading.
+* Autopilot now has modes to track a VOR and GS.
+* Added custom joystick client support so sim can be flown from a
+ remote joystick connected to another machine. This is in support of
+ some custom hardware located in the human factors research lab of the
+ university of minnesota.
+* HUD controls are a bit different "h" toggles through day/night/off
+ modes and "H" cycles through brightness levels.
+* Norman Vine contributed code to optionally do antialiased hud lines
+ on hardware that supports this. Norman also contributed additional
+ hud cleanups and updates.
+* Updates to JSBsim flight dynamics code that includes a generic
+ reconfigurable flight control system, a initial state trimming routine,
+ support for wind and weather, support for flaps, independent trim control,
+ config files changes
+* Updates to LaRCsim flight dynamcis code contributed by UIUC that
+ allows loading aircraft specifications at runtime from config files.
+ UIUC is using flightgear as a platform to do icing research. The UIUC
+ aircraft use the c172 gear model for now which causes some weirdness
+ on the ground for some of the larger aircraft.
+* Flight model no longer has to be chosen at compile time.
+* Separated ephemeris code from the actual sky rendering code and gave
+ this whole section a big overhaul. The moon should now consistantly
+ have the correct phase.
+* Rebuilt the sky dome using ssg.
+* Removed dependencies on mat3.h and friends (old srgp support lib)
+* Airport lookups now done through gdbm (a light weight embedded database.)
+* Converted ssgVTable's to ssgVtxTables which do proper memory
+ management and should facilitate use of compiled vertex arrays once
+ ssg add support for these.
+* Overhauled autopilot internals, separated out the gui controls from
+ the actual autopilot code.
+* Cygwin32 build fixes
+* MSVC++ build fixes
+* Mac build fixes
