+
+* NOMINMAX fix for cygwin/gcc-3.2
+* Renamed External FDM to NullFDM
+* New module/submodule system.
+* IRIX build fixes
+* Restructured some of the initialization code to facilitate reseting the sim
+ to alternate presets (airport, runway, offset distance, altitude, speed, etc.)
+* Fixed DG heading bug hold to work with new instrumentation updates.
+* Updates to autopilot to let it work with perfect values as a compile time
+ option.
+* Split Nav/Com units, and DME out into their own source files.
+* Fixes to support newer versions of plib/cvs
+
+
+New in 0.8.0
+* September 7, 2002
+
+* The world is now populated with random ground objects with
+ appropriate type and density for the local ground cover type
+ (buildings, water towers, farm houses, silos, cows, trees, etc.)
+* Many (most?) ground textures updated for a much nicer, more coherent,
+ more realistic overall look and feel.
+* Added a java client library for FlightGear.
+* Added some external scripting examples (python.)
+* Implemented a Bendix/King KT 70 transponder.
+* Implemented a Bendix/King KR 87 adf.
+* Added support for 3d instrument panels inside 3d cockpits.
+* Added support for animation of 3d models tied to internal properties.
+* New/updated aircraft include: Cessna 172, Piper J3 Cub, DC-3, A4
+ Skyhawk, Cessna 310, 747, 1903 Wright Flyer (non-linear with stall
+ modeled, based on wind tunnel data.)
+* Convert the magic carpet into a UFO, complete with sound effects and
+ a 3d model (based on real world data of course.) :-)
+* Environment manager overhaul
+* Support for a base wind speed with gusts.
+* Support for a base wind direction with variation.
+* Support for more dynamically reconfigurable cloud layers. Cloud
+ layers are no longer hard coded.
+
+* Updates and additions to the FAQ
+* Improvements to the sound effects module.
+* Autopilot fixes to allow it to work much better on large airliners.
+* Added a generic interface for running the flight dynamics model as a
+ separate process communicating via a network connection.
+* Synced with the latest JSBSim code.
+* Synced with the latest UIUCmodel code.
+* Many fixes and updates to the YASim FDM (fixed flap drag issue, new
+ tail wheel lock, lots of solver fixes, and fixes to other internal
+ stuff.)
+* Added support for menus defined in an xml file.
+* Make the help system start more robustly/quickly in Win32
+* Added support for detecting the name of a joystick and using the
+ appropriate default joystick config file.
+* Overhauled the remote/network property interface.
+* Added a --show-aircraft option to dump out a list of all the
+ available aircraft you can select with the --aircraft=NAME option.
+* Added a --random-wind command line option.
+* --wind= option can now contain ranges,
+ i.e. --wind=min_dir:max_dir@min_speed:max_speed; the system will
+ automatically vary the wind within these ranges.
+* A "physical" crash (i.e. too-hard impact with the ground) causes the
+ sim to freeze. You can then reset the sim to the starting state
+ with the menu->reset option.
+
+* Support in the scenery tile cache for maintaining tiles in the cache
+ relative to several view points that could be *very* far apart.
+* Brake makes the magic carpet fly backwards.
+* Many clean ups, fixes, and improvements with the tile pager. Memory free
+ is now done incrementally and spread out through multiple frames to hide it.
+* Modernized the autoconf/make scripts.
+* Cleaned up old cruft from the build system.
+* Default to using FGEnvironment
+* Removed support for efence (in favor of valgrind.)
+* Bumped minimum plib version required up to 1.4.2, however the latest
+ cvs (and hopefully release) works much better.
+* Added valgrind debugging config files/scripts.
+* Weeded out many warnings/errors flagged by valgrind.
+* Overhauled the FGSubsystem class.
+* Fixed reporting of winds, cloudbase and altimeter setting.

+* Added internal support for turning each tank on/off individually.
+* Added support for a fuel selector switch.
+* Fixes to builtin property browser.
+* Fixed several math overflow problems with time elapsed calculations
+ that had crept in. These would cause some things to stop updating
+ (like portions of the instrument panel, and radio station frequency
+ matching.)
+* Updates to the network OpenGC interface.
+
+* Irix fixes.
