+New in 0.54
+* More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
+ Hotchkiss.)
+* Bug fixed that was causing odd display artifacts due to a degenerate
+ fragment being created for every tile.
+* Bug fixed that caused scenery generation to go bad (misplaced fclose on an
+ invalid file descriptor.)
+* Code changes to support g++ 2.7 STL (from Bernie Bright)
+
+New in 0.53
+* Some initial "GameGLUT" support contributed by Gary R. Van Sickle
+ (tiberius@braemarinc.com)
+* Tracked down and eliminated some memory access type bugs that were
+ causing segfaults on some platforms, with some compilers using various
+ optimization flags.
+* Assorted code optimizations submitted by Norman Vine.
+* Renamed fg -> fgfs
+* Shuffled files.
+ - Created a new directory Simulator/Airports/ to handle airport data
+ specific tasks
+ - Created Simulator/Object/ to handle basic rendering objects
+* Panel code update from Friedemann Reinhard (use --enable-panel to activate)
+* Contributions from Bernie Bright
+ - Created some new classes to enable pointers-to-functions and
+ pointers-to-class-methods to be treated like objects. These objects
+ can be registered with fgEVENT_MGR.
+ - File "Include/fg_callback.hxx" contains the callback class defns.
+ - Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
+ some minor tweaks to STL usage.
+ - Added file "Include/fg_stl_config.h" to deal with STL portability
+ issues. Added an initial config for egcs (and probably gcc-2.8.x).
+ Don't have access to Visual C++ so I've left that for someone else.
+ - This file is influenced by the stl_config.h file delivered with egcs.
+ - Added "Include/auto_ptr.hxx" which contains an implementation of the
+ STL auto_ptr class which is not provided in all STL implementations
+ and is needed to use the callback classes.
+ - Deleted fgLightUpdate() which was just a wrapper to call
+ fgLIGHT::Update().
+ - Modified fg_init.cxx to register two method callbacks in place of the
+ old wrapper functions.
+ - The new classes in libmisc.tgz define a stream interface into zlib.
+ I've put these in a new directory, Lib/Misc. Feel free to rename it
+ to something more appropriate. However you'll have to change the
+ include directives in all the other files. Additionally you'll have
+ add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
+
+ The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
+ test so I've included the required changes in config.tgz.
+
+ There are a fair few changes to Simulator/Objects as I've moved
+ things around. Loading tiles is quicker but thats not where the delay
+ is. Tile loading takes a few tenths of a second per file on a P200
+ but it seems to be the post-processing that leads to a noticeable
+ blip in framerate. I suppose its time to start profiling to see where
+ the delays are.
+
+ I've included a brief description of each archives contents.
+
+ Lib/Misc/
+ zfstream.cxx
+ zfstream.hxx
+ C++ stream interface into zlib.
+ Taken from zlib-1.1.3/contrib/iostream/.
+ Minor mods for STL compatibility.
+ There's no copyright associated with these so I assume they're
+ covered by zlib's.
+
+ fgstream.cxx
+ fgstream.hxx
+ FlightGear input stream using gz_ifstream. Tries to open the
+ given filename. If that fails then filename is examined and a
+ ".gz" suffix is removed or appended and that file is opened.
+
+ stopwatch.hxx
+ A simple timer for benchmarking. Not used in production code.
+ Taken from the Blitz++ project. Covered by GPL.
+
+ strutils.cxx
+ strutils.hxx
+ Some simple string manipulation routines.
+
+ Simulator/Airports/
+ Load airports database using fgstream.
+ Changed fgAIRPORTS to use set<> instead of map<>.
+ Added bool fgAIRPORTS::search() as a neater way doing the lookup.
+ Returns true if found.
+
+ Simulator/Astro/
+ Modified fgStarsInit() to load stars database using fgstream.
+
+ Simulator/Objects/
+ Modified fgObjLoad() to use fgstream.
+ Modified fgMATERIAL_MGR::load_lib() to use fgstream.
+ Many changes to fgMATERIAL.
+ Some changes to fgFRAGMENT but I forget what!
+
+New in 0.52
+* Stars added in 8 stages as sky gets darker for a smoother more realistic
+ transition.
+* rewrote star loader to significantly improve load times.
+* Tweaked sky brightness and dawn/dusk colors.
+* Fixed a small problem with moon rendering.
+* Fog color tries to track the sky color at the center of view in sunrise
+ and sunset situations.
+* Optimizations from Norman Vine
+* Code fixes and tweaks from Charlie Hotchkiss.
+* Added an --enable/disable-sound option.

+
+New in 0.51
+* Translucent menus
+* Various HUD intensities so you can find something that is readable for the
+ current conditions and lighting.
+* Tie visibility to far clip plane & view frustum culling so reducting
+ visibility can increase frame rates by increasing what is culled.
+* Fixed stupid bug with misplaced initial position.
+* Hopefully fixed a bug when parsing system.fgfsrc on windoze.
+
+New in 0.50
+* HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
+ position indicators are back)
+* Only draw the PUI cursor if Mesa/Glide/Fullscreen.
+* Added mipmapping.
+* Calculate the model view transformation matrix once per tile per iteration.
+ Then glLoadMatrixd() it for each fragment rather than calling push(),
+ translate(), pop().
+* Added a basic splash screen.
+* Added support for switching between fullscreen and window mode for
+ Mesa/3dfx/glide.
+* added an enable/disable splash screen option
+* added an enable/disable intro music option
+* added an enable/disable instrument panel option
+* added an enable/disable mouse pointer option

+
+New in 0.49
+* Managment of multiple textures
+* Incorporated Friedemann Reinhard's initial panel code.

+* Build the non-shared pieces of the FG sim as static libs.
+
+New in 0.48
+* Incorporated Steve Baker's PUI user interface library written
+ entirely on top of OpenGL
+* Incorporated Steve Baker's Audio library which currently only
+ supports Linux, but a win32 port is very close to being done.
+* Sort object fragments by material property before rendering. This
+ will be a big help to performance when we start including objects
+ with a wide variety of material properties and textures.
+* Overlapped scenery tiles to reduce the chance of an occasional
+ floating point precission induced gaps.
+* Fixed a bug in zlib exposed by Borland Win32 compiler.
+* Impose a maximum triangle area during scenery generation so even
+ very flat areas will get split into a few smaller sub triangles.
+* Fine grained (fragment level) view frustum culling.
+* view transformation optimizations -- Norman Vine.
+* Fixed polygon winding problem in scenery generation, so all
+ tri-strips are wound counter clockwise (opengl default).
+
+New in 0.47
+* Course (per tile) view frustum culling.
+* Added a command line option to specify --fg-root which will override
+ $FG_ROOT
+* Hard coded default locations for FG_ROOT for situations when nothing
+ is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
+* Restructured the command line processing code so that it can process
+ these sames comands (one per line) out of a config file.
+* Added a command line option to specify field of view. This is
+ adjustable at run time using "X / x". Supporting code contributed
+ by Norman Vine.
+
+New in 0.46:
+* Complete C++ re-write of the HUD section.
+* Miscellaneous bug fixes and tweaks.

+* Added an option to control the number of neighboring tiles that are drawn
+
New in 0.44:
+* Fixed a horible bug that cause the time to be *WAY* off when
+ compiling with the CygWin32 compiler.
+* Wrap up zlib so we can conditionally compile back in normal behavior
+ on systems that have trouble building zlib.
* Minor adjustment to texture coordinate generation to reduce texture
swimming.
-* Added an option to enable/disable texture maps
+* Added a command line option to enable/disable texture maps
* Minor transformation adjustments to try to keep scenery tiles closer
to (0, 0, 0) GLfloats run out of precision at the distances we need
to model the earth, but we can do a bunch of pre-transformations
* command line option to set starting position by airport ID
* Cleaned up initialization sequence to eliminate interdependencies
between sun position, lighting, and view position. This creates a
- valid single pass initialization path.
+ valid single pass initialization path.
* use already calculated LaRCsim values to create the roll/pitch/yaw
transformation matrix
