4 * Configure script does a sanity check for the existance of openal.
5 * Better pthreads detection for FreeBSD.
6 * Abstract out the location of gl.h, glu.h, and glut.h so we can more
7 easily support MacOS which puts these in an oddball location.

9 * Add a name parameter to the waypoint class for supporting a route
10 manager in the flightgear gps module.

13 the next frame rather than entering an infinite loop.
15 * Fixes to property tree loading and saving.
16 * Make volume inaudible at startup.
18 * For low density cloud coverages, blend the layer to nothing as we pass

77 * Some lighting tweaks and fixes (especially for taxiways.)
78 * Added support for "blend" and "scale" and "texture" animations.
79 * Added support for animating rotations around an arbitrary axis (so the
80 aircraft designer isn't forced to figure out animations as a combination
81 of rotations around X, Y, and X axes.
82 * Updates to sky dome modeling and make cloud layers follow the curve
83 of the earth (sort of.)

106 management code from FlightGear into SimGear and did a substantial
107 amount of restructuring and dependency clean up in the process.
108 Created a "scene" subdirectory with sub-subdirectories for material
109 management, basic model and model animation management, sky
110 rendering, and low level loaders for the "TerraGear" tile object format.
111 * Removed support of the flat shaded and non-textured material
112 property varients. You can still do these things, but extra states
113 are no longer set up automatically.
114 * Removed 3d clouds from the default build ... these need a maintainer
115 or better yet, a complete plib-based rewrite.
116 * Moved the FlightGear sound effect manager code over to SimGear.
117 * Updated the cloud layer surface to better follow the inverted bowl
119 * Much work on cloud/sky coloring, and also much work on
120 sunset/sunrise coloring.

154 * Removed efence support (in favor of valgrind.)
156 * Added a javascript interpreter.
157 * SGSocket reimplimented on top of plib/net libs.
158 * Added a new random number generation algorithm.
159 * Total rewrite of the strutils package.
161 * Patch for the random number seed.
162 * IA-64 w/ Intel compiler fixes.
166 * Code clean ups to remove warning messages.
167 * Optimizations in sg_binobj to reduce the amout of memory copying
168 needed when loading a binobj format file.
169 * Fixed a couple places where variables could be used before they were
171 * Various property manager fixes and improvements.

173 * Made the sky dome more flexible to facilitate use in other applications.
179 * Created a src/libs subdirectory for several packages that need to be
180 installed by the user but are used by many other packages and may already
181 be installed. So we just bundle the source separately as a convenience
182 if the user needs to build and install these.
183 * Upgrade to zlib-1.1.4 (security fix)
184 * Upgrade to metakit-2.4.2-32.tar.gz (latest upstream release)
185 * Added support for point objects in the scenery file format.

187 For each major primative type: points, triangles, fans, and strips, you
188 can specify an index list of vertices, normals, colors, and texture
189 coordinates. You can skip any of these you like to save on space.
190 * Added support for new file features in the binary -> ascii scenery file
192 * Various code clean ups.
193 * Separate XML I/O operations into a separate header file.

198 New in 0.0.17 (final)
201 * Explicitely reset the glBlendFunc() after drawing the moon for the
202 Voodoo2 linux driver since it seems to have a bug in glPopAttrib().

247 * Created a mailing list for cvs commit messages.
248 * Fixed a potential array under/over run bug in interpolator.cxx
249 * Removed all references to SGValue from the property manager. Added
250 support for an "archive" bit in the property manager to control
251 which values get written out.
252 * Added SGCommandState class so that commands can compile and save
253 copies of their arguments for efficiency if they are called multiple
255 * Added Brian Baul's "tr" tiled rendering low level support library.
256 This along with some higher level code in flightgear allows us to do
257 ultra-hires tiled screen dumps suitable for large format printers.
263 * Various bug fixes, tweaks, and optimizations.
264 * Added a command manager (analogous to the property manager)
265 * Better Irix Mips support.

280 can be accessed via the SimGear web page.
281 * Many FG -> SG name space changes for better consistancy throughout
283 * Added property aliases, repeated name tags, and a general xml
284 inclusion facilities. Many other property manager clean ups
285 following a complete rewrite.
286 * Fixed some critical null pointer bugs in property manager.
287 * Magnetic variation can now be fetched for any arbitrary location.
292 * Added a module to manage waypoints and routes, calculate bearing and
293 distance to next waypoint, lateral distance off route, etc.
294 * Moved some of the basic time management code over from flightgear.
295 * Bucket dimensions can be returned in meters
296 * Added SOCK_STREAM (TCP) socket support to the networking code.
297 * Updated random number generator interface so application can provide
298 it's own seed value as well as use the default time seed.
299 * Added a routine to calculate the distance between a point and a line segment.
300 * Updates to the property manager and the property list loader/saver.
301 * Added an explanation of the rational behind our terrain texture coordinate
303 * Fixed sky dome so that the color at the horizon will always match
304 the specified fog color.
305 * Did a fair amount of fg -> sg name space updating (lots left to do.)
306 * Added support for KAI C++ on linux.
314 * Added support for reading and writing xml files (easyxml)
315 * Then updates to property manager and xml code.

344 * Added support for RedHat package building contributed by Habibie
345 <habibie@MailandNews.com>
346 * Added gdbm to SimGear. Many systems will already have gdbm installed so
347 it is only built if it doesn't already exist on the user's platform.
348 gdbm is a set of database routines that use extendible hashing and works
349 similar to the standard UNIX dbm routines. This guarantees the availability
350 of gdbm to any application that uses SimGear.
351 * Optimizations and bullet proofing of magnetic variation code by Norman
357 * Added Nima World Magnetic Model 2000 contributed by Ed Williams
363 * Restructured directory layout to facilitate windows/mac IDE builds.
