+
+
+New in 0.9.10
+* April 5, 2006
+
+* Many improvements to the multi-player mode. Other airplanes are now

+ local festival server to be converted to spoken speech output.
+* Added a detailed model of the Honeywell MK VIII EGPWS ground
+ proximity warning system.

+ about anything including external programs. Later we added the
+ ability to place an object at the click point as well.
+* Add a feature to play one-off wav files. These are qeued and played
+ sequentially. This was then leveraged to build an ATC background

+* 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
+
+New in 0.7.2
+* February 17, 2000
+* Lots of code reorganizations
+* Build requires plib-1.1.x
+* Build requires SimGear-0.0.x
+* LaRCsim/c172 is now the default aircraft model.
+* Added flaps support to control model.
+* Lots of updates and tweaks for the LaRCsim/c172 model.
+* Use a more standard texture/blend mode combination for sun/moon halos to
+ avoid render path that's not supported by all cards/drivers.
+* Change reported speed on hud from V_equiv_kts to V_calibrated_kts
+* Instrument panel rewrite by David Megginson. This isn't quite as flashy
+ as the first pass, but is much more functional, plays much better with
+ opengl, and it should be relatively easy for someone with graphical skills
+ to make it look more spiffy.
+* MacOS fixes contributed by Darrell Walisser.
+* Many JSBsim updates.
+* Added a screen snapshot facility (F3).
+* Added a load/save state function contributed by David Megginson.
+* Added support for various I/O protocols and channels so that flightgear
+ can communicate with itself and other programs through a variety of means.
+* Bug fix: The aircraft model used for external views was being included in
+ the height above terrain check so when the view position and the aircraft
+ model collided the current altitude kept getting pushed up to compensate,
+ but of course the aircraft model would get pushed up as well because it
+ tracks the current aircraft position and orientation. Thus you had a never
+ ending cycle ...
+* Oliver's multiplayer network code now moved to his own subdirectory:
+ NetworkOLK
+* Added simulated cloud puffs as we pass through the cloud layer.
+* Cleaned up some memory leaks occuring between ssg and flightgear.
+* Update to Christian's weather data base code.
+
+New in 0.7.1
+* Durk Talsma added a nifty cloud layer.
+* Default to Christian Mayer's new weather system.
+* Added routines to do screen printing contributed by Mark Vallevand.
+* Added routines to do screen shots to ppm graphics file (all platforms)
+ contributed Rich Kaszeta.
+* Added a magic carpet (aka slew) mode.
+* Added a hot air balloon simulator mode. (alpha)
+* Added a simple (direct lincage) autocoordation feature.
+* Added a mode to control view (side to side and up and down) with the mouse.
+* Fixed a DEM decoding problem which caused most of the terrain to be 256
+ meter too high (and regenerated the world scenery with proper elevations.)
+* Updates to JSBsim.
+* Added support for a pilot view offset from the center of gravity.
+* Various platform portability fixes.
+* Updated time-offset/syncing command line options.
+* Updated the FDM <==> Flight Gear interface to be more object oriented.
+ This should hopefully pave the way for being able to simulate several
+ concurrent entities.
+* Removed unimplemented menu entries.
+* Various scenery tools changes and enhancements in preparation for adding
+ runways (hopefully for the next release.)
+
+New in 0.7.0
+* Autopilot can now fly great circle routes.
+* Incorporated a first stab at some networking code contributed by Oliver
+ Delise.
+* Added Christian Mayer's new weather subsystem.
+* Started adding support for "external" views ... still needs some work.
+* Added a flight model acceleration funtion.
+* Added support for mouse yoke control contributed by David Megginson.
+* FDM model hertz now definable from the command line.
+* Added initial timezone support so the user can have better control and more
+ options for setting the starting time of the sim.
+* We now draw nonexistant tiles as ocean which means we only have to create
+ and distribute tiles that contain some sort of land mass.
+
+* Replaced basic render engine with plib's ssg (simple scene graph).
+* Now expect plib to be installed in it's one true and official location.
+* Added support for timegm() if it exists which explicitely expects GMT input.
+* A bit of your basic code reorganization and shuffling.
+
+* Removed tools dependency on libgfc. Functionality is now covered by
+ shapelib which has been added into the Tools tree.
+* Added support for the wonderful GSHHS global land mass data set.
+* Removed dependecy on process-dem.pl script.
+* Created a new distributed/parallel tile build system ... hmmm kind of super
+ computer or beowulf style stuff for getting large chunks of scenery built
+ as fast as possible.
+* Only generate tiles that have land mass data since the sim can recreate pure
+ ocean tiles on the fly.
+* First stab at a water flattening scheme to prevent oceans, lakes, and rivers
+ from running up and down the sides of hills.
+* Changed the default "Work/" subdirectory layout.
+* Updates to better handle segment boundaries in preparation for real airport
+ runway and lighting modeling.
+* Updates and enhancements to my polygon management class.
+
+* Updates to JSBsim.
+* Updates to Tony's c172 model.
+* Updated getting started guide from Micheal Basler.
+
+* FreeBSD portability tweaks.
+* MACos portability tweaks.
+* Borland C++ tweaks.
+* MSVC++ tweaks.
+
+New in 0.6.0
+* Tons of improvements with scenery creation. Inter-tile gaps have been
+ fixed, distorted textures have been fixed, real coastlines have been added,
+ and many other subtle improvements.
+* Tools for parallelizing the scenery building tasks. For instance by using
+ 20 machines in parallel, scenery for the entire USA can be regenerated in
+ just over 4 hours vs. 70+ hours on a single machine.
+* Texture scale can be specified (and changed)( in the materials file. The
+ sim must be rerun for the change to take effect.
+* Windows now uses plib joystick code so rudder pedals should now work.
+* Now builds against Steve Baker's plib (portable game devel library)
+ distributed separately (www.woodsoup.org/~sbaker/plib/)
+* Many source code changes for the MacOS port contributed by Darrell
+ Walisser (the port isn't quite there yet ...)
+* Source code changes for better compiling with the Borland compiler.
+* Source code changes for better compiling with the native Irix compilers.
+* Fixed a bug so you can now fly across the international date line (or
+ more precisely the division between longitude = +/-180.
+* Tweaks to the Astro section contributed by Durk Talsma.
+* Autopilot improvements contributed by Norman Vine.
+* Fonts/characters now drawn with texture maps for increased speed.
+* Instrument panel can be toggled on and off with "P".
+* GUI interface for tweaking some autopilot parameters.
+* HUD appearance and layout changes contributed by Norman Vine, includes
+ faster font drawing for much better performance.
+* Reset function added to reset you to your starting conditions.
+* GUI function to enter a new airport id (and be transported there)
+* Added serial output support for an "in-development" full motion cockpit.
+* "Just in time" texture loading to reduce initial sim loading time.
+
+
+New in 0.59 (This is an intermediate/stepping stone release. Skip this
+ release if you are interested in stability.)
* IRIX portability changes and support for native SGI compilers.
* Solaris portability tweaks
* Incorporated some MacOS portability changes (although the port is not
