6 as well as onto the ground (by Harald Johnsen.)
7 * New 3d volumetric clouds by Harald Johnsen (along with several rounds of
8 followup fixes and improvements.)
9 * Remove Mark Harris's old 3d clouds because they were never properly
10 integrated. And we now have new 3d clouds.

41 * Make volume inaudible at startup.
43 * For low density cloud coverage, blend the layer to nothing as we pass

105 aircraft designer isn't forced to figure out animations as a combination
106 of rotations around X, Y, and X axes.
107 * Updates to sky dome modeling and make cloud layers follow the curve
108 of the earth (sort of.)

131 management code from FlightGear into SimGear and did a substantial
132 amount of restructuring and dependency clean up in the process.
133 Created a "scene" subdirectory with sub-subdirectories for material
134 management, basic model and model animation management, sky
135 rendering, and low level loaders for the "TerraGear" tile object format.
136 * Removed support of the flat shaded and non-textured material
137 property variants. You can still do these things, but extra states
138 are no longer set up automatically.
139 * Removed 3d clouds from the default build ... these need a maintainer
140 or better yet, a complete plib-based rewrite.
141 * Moved the FlightGear sound effect manager code over to SimGear.
142 * Updated the cloud layer surface to better follow the inverted bowl
144 * Much work on cloud/sky coloring, and also much work on
145 sunset/sunrise coloring.

181 * Added a javascript interpreter.
182 * SGSocket reimplemented on top of plib/net libs.
183 * Added a new random number generation algorithm.

187 * IA-64 w/ Intel compiler fixes.
191 * Code clean ups to remove warning messages.
192 * Optimizations in sg_binobj to reduce the amount of memory copying
193 needed when loading a binobj format file.

206 be installed. So we just bundle the source separately as a convenience
207 if the user needs to build and install these.
208 * Upgrade to zlib-1.1.4 (security fix)
209 * Upgrade to metakit-2.4.2-32.tar.gz (latest upstream release)

213 can specify an index list of vertices, normals, colors, and texture
214 coordinates. You can skip any of these you like to save on space.
215 * Added support for new file features in the binary -> ascii scenery file
217 * Various code clean ups.
218 * Separate XML I/O operations into a separate header file.

223 New in 0.0.17 (final)
226 * Explicitely reset the glBlendFunc() after drawing the moon for the
227 Voodoo2 linux driver since it seems to have a bug in glPopAttrib().
233 * Replaced some cout's with SG_LOG's

271 being able to find a timezone.
272 * Created a mailing list for cvs commit messages.
273 * Fixed a potential array under/over run bug in interpolator.cxx
274 * Removed all references to SGValue from the property manager. Added
275 support for an "archive" bit in the property manager to control
276 which values get written out.
277 * Added SGCommandState class so that commands can compile and save
278 copies of their arguments for efficiency if they are called multiple
280 * Added Brian Baul's "tr" tiled rendering low level support library.
281 This along with some higher level code in flightgear allows us to do
282 ultra-hires tiled screen dumps suitable for large format printers.
288 * Various bug fixes, tweaks, and optimizations.
289 * Added a command manager (analogous to the property manager)
290 * Better Irix Mips support.

309 inclusion facilities. Many other property manager clean ups
310 following a complete rewrite.
311 * Fixed some critical null pointer bugs in property manager.
312 * Magnetic variation can now be fetched for any arbitrary location.
317 * Added a module to manage waypoints and routes, calculate bearing and
318 distance to next waypoint, lateral distance off route, etc.
319 * Moved some of the basic time management code over from flightgear.
320 * Bucket dimensions can be returned in meters
321 * Added SOCK_STREAM (TCP) socket support to the networking code.
322 * Updated random number generator interface so application can provide
323 it's own seed value as well as use the default time seed.
324 * Added a routine to calculate the distance between a point and a line segment.
325 * Updates to the property manager and the property list loader/saver.
326 * Added an explanation of the rational behind our terrain texture coordinate
328 * Fixed sky dome so that the color at the horizon will always match
329 the specified fog color.
330 * Did a fair amount of fg -> sg name space updating (lots left to do.)
331 * Added support for KAI C++ on linux.
339 * Added support for reading and writing xml files (easyxml)
340 * Then updates to property manager and xml code.

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