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

39 * Fix cloud positioning/animation bugs.
40 * Fix an off-by-one error in props_io.cxx
41 * Clip audio gain (volume) to 1.0

70 * Some lighting tweaks and fixes (especially for taxiways.)
71 * Added support for "blend" and "scale" and "texture" animations.
72 * Added support for animating rotations around an arbitrary axis (so the
73 aircraft designer isn't forced to figure out animations as a combination
74 of rotations around X, Y, and X axes.
75 * Updates to sky dome modeling and make cloud layers follow the curve
76 of the earth (sort of.)

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

146 * Modernized the autoconf/make scripts, plus lots of tweaks and enhancements.
147 * Removed efence support (in favor of valgrind.)
149 * Added a javascript interpreter.
150 * SGSocket reimplimented on top of plib/net libs.
151 * Added a new random number generation algorithm.
152 * Total rewrite of the strutils package.
154 * Patch for the random number seed.
155 * IA-64 w/ Intel compiler fixes.
159 * Code clean ups to remove warning messages.
160 * Optimizations in sg_binobj to reduce the amout of memory copying
161 needed when loading a binobj format file.
162 * Fixed a couple places where variables could be used before they were
164 * Various property manager fixes and improvements.
165 * Fixes to cloud layer management code.
166 * Made the sky dome more flexible to facilitate use in other applications.
172 * Created a src/libs subdirectory for several packages that need to be
173 installed by the user but are used by many other packages and may already
174 be installed. So we just bundle the source separately as a convenience
175 if the user needs to build and install these.
176 * Upgrade to zlib-1.1.4 (security fix)
177 * Upgrade to metakit-2.4.2-32.tar.gz (latest upstream release)
178 * Added support for point objects in the scenery file format.

180 For each major primative type: points, triangles, fans, and strips, you
181 can specify an index list of vertices, normals, colors, and texture
182 coordinates. You can skip any of these you like to save on space.
183 * Added support for new file features in the binary -> ascii scenery file
185 * Various code clean ups.
186 * Separate XML I/O operations into a separate header file.
187 * Major property manager rewrite, then lots of followup cleaning and
191 New in 0.0.17 (final)
194 * Explicitely reset the glBlendFunc() after drawing the moon for the
195 Voodoo2 linux driver since it seems to have a bug in glPopAttrib().

234 * Other various tweaks for Irix.
235 * Added a virtual destructor to XMLVisitor to fix a warning message.
236 * Check for valid hostname lookup in sg_socket.cxx
237 * Add a function to return modified julian date without creating an
238 entire SGTime class. This avoids an extraneous warning about not
239 being able to find a timezone.
240 * Created a mailing list for cvs commit messages.
241 * Fixed a potential array under/over run bug in interpolator.cxx
242 * Removed all references to SGValue from the property manager. Added
243 support for an "archive" bit in the property manager to control
244 which values get written out.
245 * Added SGCommandState class so that commands can compile and save
246 copies of their arguments for efficiency if they are called multiple
248 * Added Brian Baul's "tr" tiled rendering low level support library.
249 This along with some higher level code in flightgear allows us to do
250 ultra-hires tiled screen dumps suitable for large format printers.
256 * Various bug fixes, tweaks, and optimizations.
257 * Added a command manager (analogous to the property manager)
258 * Better Irix Mips support.

262 automake configuration files.)
263 * Removed total size limitation on interpolation table module.
264 * Various Cygwin fixes.
265 * Added some convenience functions to point3d.
266 * Various compiler warning fixes.

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

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