Changelog

AI: fix frequent ground crashes, improve yaw/roll behavior in precise attack/formation mode
Prevent player from getting 200% trust by typing 'a' beyond 100%
Fix memory leak related to coastline 'foam'
water using vertex/fragment shaders
realistic day time simulation (colors, lightpos etc)
switch back to dynamic lighting
avoid opengl's buld in clipping for coastline, use own clipping instead
implementation of simple LOD for terrain mesh
many smaller changes, restructuring, code rewriting, bug fixes

Implementation of kind of GUI toolkit / framework
start with a GUI, main-, settings- and instant action menu
add some polygons for coastline
add an option for joystick number to use
add an option for joystick / keyboard sensitivity
probably added some more options ...
terrain engine uses CPU-multithreading now
Improvement to flight model, including proper equations of motion and added lateral modes (roll/yaw battle), improved short period pitch mode and more ...
adapt AI for flight model changes
fix frustum culling for widescreen resolutions
add a sky sphere for realistic sky shading
improve fog behavior, add far distance alpha fading for terrain

add new options for disabling vertex arrays and detailed coast line
add a progress view to loading screen
improve physics related to starts/landings
preparations for menu loop, fix several memory leaks, memory leak check
high resolution coastline based on precalculated (by some kind of midpoint displacment) display lists.
some changes for terrain engine in order to improve performance with higher view distances
differ between fog and terrain distance, use far clipping plane to avoid hopping
changes to options and setting.cfg file
use vertext arrays for certain terrain tiles
Some work on textures and terrain
frustum culling adaption for widescreen resolutions, underwater coastline
sky should reach farer to 'make a horizon' on high altitudes
some work on textures

AI: Implement some attack (yaw/pitch mode) and defense (panick mode) tacktics
AI: improve ground crash prevention
Make AI fighter able to roll a little (toward it's target) during turning.
Make use of rudder possible.
One can now use both Y and Z key for throttle decrease.
Do not use linear fog any longer (avoid problems with large triangles on older graphic cards).
fix frustum culling (tiles disapeared when flying at high altitude)
fix integer overflow caused disapearing aircrafts if higher view distances choosed
disable padlock if a opponent aircraft got killed
enable use of more than one opponent aircraft

Implementation of basic enemy AI, suitable for dogfights, still not very marture. The enemy planes can do various roll/turn combinations in order to get behind your or avoid you to get behind them. It also will try to avoid a ground crash. There aren't yet special defence/attack tactics.
change fire key from 'C' to 'SPACE'
make it possible to use the joystick butten for fireing

implement using the SDL for input and timer handling and window creation. This replaces the X/Linux specific stuff. (The possibility to use X/Linux specific stuff and libJSW for joystick input is still contained in the sourcecode and one could reactivate it sometimes, i.e. independency from SDL if wanted from somebody)
Windows port
Check if used openGL extensions are available, else disable certain features which use these extensions (Multitexture with more than two textures, dot3 for bumpmapped water, vertex buffer objects (VBO's))
for Windows, get extension related function pointers (else it would not work at all)
implement framerate limitation differently (platform independent)
additional joystick calibration (only if SDL is used)
make joystick axes invertion possible (with a new settings oprtion
add an ingame menu (unfortunately not yet beautiful) to access functions like joystick calibration and programm exiting
implement possibility to pause the game (to be able to make screenshots or so)
loading screen, though very ugly
maybe something more ...

This is the first release.
