+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.
+* Added a pause key "p"
+* Added command line options to specify initial position and orientation.
+* Added command line option to start in paused or unpaused state.
New in 0.51
* Translucent menus
* 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
