+New in 0.3.9
+* November 17, 2005
+
+* Add support for OpenAL 1.1 (with a separate alut library.)
+* Add support for volumetric shadows. Aircraft can cast shadows on themselves
+ as well as onto the ground (by Harald Johnsen.)
+* New 3d volumetric clouds by Harald Johnsen (along with several rounds of
+ followup fixes and improvements.)
+* Remove Mark Harris's old 3d clouds because they were never properly
+ integrated. And we now have new 3d clouds.
+* Add support for seasonal textures (with a set of winter textures added
+ to FlightGear.)
+* Updated Nasal scripting system. Adds several new syntax convenience
+ features, fixes parser bugs, fixes several internal bugs.
+* Our 3d cockpit jitter problem is fixed (woohoo!)
+* Add code to support rendering to a texture.
+* Allow "tip" popups to pop themselves down after the appropriate
+ timeout, even if the sim time is paused.
+* Various low model level animation fixes and additions ... color,
+ transparency, 'chrome' effects, randomized spin, etc.
+* Create our own portable stdint.h implementation.
+* Fixed several memory leaks.
+* removeChildren() added to the property system.
+* Fix many cases of 'const'.
+* Fixes for cygwin, solaris/sun, Mac OS X, MSVC, gcc-3.4.x.
+
+
+New in 0.3.8
+* January 18, 2005
+
+* Configure script does a sanity check for the existence of openal.
+* Better pthreads detection for FreeBSD.
+* Abstract out the location of gl.h, glu.h, and glut.h so we can more
+ easily support MacOS which puts these in an oddball location.
+* Added two new debug output types for instrumentation and systems.
+* Add a name parameter to the waypoint class for supporting a route
+ manager in the flightgear gps module.
+* Make display list usage optional.
+* Event manager: specifying a zero delay will force event execution in
+ the next frame rather than entering an infinite loop.
+* gcc-4.0 fix.
+* Fixes to property tree loading and saving.
+* Make volume inaudible at startup.
+* Solaris fixes.
+* For low density cloud coverage, blend the layer to nothing as we pass
+ through instead of fully engulfing the aircraft in the cloud.
+* Add several new capabilities to the texture management code for building
+ normal maps and doing some simple on-the-fly effects on textures.
+* Better error message for sound problems.
+* Add support for binding a thread to a specific CPU.
+
+
+New in 0.3.7
+* October 12, 2004
+
+* Add support for parsing xml from an in memory buffer, not just a file.
+* Don't reduce visibility for a "clear" cloud layer.
+* Add support for audio orientation (direction and cone) for internal
+ view and tower view.
+* Add support for drawing from display lists rather than in immediate mode.
+ This provides a big performance improvement on many systems.
+

+New in 0.3.6
