New in 0.2.0 * September 6, 2002 * Modernized the autoconf/make scripts, plus lots of tweaks and enhancements. * Removed efence support (in favor of valgrind.) * Added a javascript interpreter. * SGSocket reimplimented on top of plib/net libs. * Added a new random number generation algorithm. * Total rewrite of the strutils package. * Patch for the random number seed. * IA-64 w/ Intel compiler fixes. * MSVC/MINGW fixes. * Mac OS X fixes. * Irix fixes. * Code clean ups to remove warning messages. * Optimizations in sg_binobj to reduce the amout of memory copying needed when loading a binobj format file. * Fixed a couple places where variables could be used before they were initialized. * Various property manager fixes and improvements. * Fixes to cloud layer management code. * Made the sky dome more flexible to facilitate use in other applications. New in 0.0.18 * April 20, 2002 * Created a src/libs subdirectory for several packages that need to be installed by the user but are used by many other packages and may already be installed. So we just bundle the source separately as a convenience if the user needs to build and install these. * Upgrade to zlib-1.1.4 (security fix) * Upgrade to metakit-2.4.2-32.tar.gz (latest upstream release) * Added support for point objects in the scenery file format. * Additions to the binary file format to make it *much* more flexible. For each major primative type: points, triangles, fans, and strips, you can specify an index list of vertices, normals, colors, and texture coordinates. You can skip any of these you like to save on space. * Added support for new file features in the binary -> ascii scenery file decoder. * Various code clean ups. * Separate XML I/O operations into a separate header file. * Major property manager rewrite, then lots of followup cleaning and improvements. New in 0.0.17 (final) * February 16, 2002 * Explicitely reset the glBlendFunc() after drawing the moon for the Voodoo2 linux driver since it seems to have a bug in glPopAttrib(). New in 0.0.17pre2 * February 13, 2002 * Replaced some cout's with SG_LOG's New in 0.0.17pre1 * February 12, 2002 * Removed metakit and zlib from build process. Tarballs are still included for those who's systems don't provide these packages. * MSVC fixes. * IRIX fixes. * Mingwin fixes. * Mac OS X fixes. * FreeBSD fixes. * Added support for Intel's C++ compiler under Linux. * Attempt to build in support for various non-compatible automake/autoconf versions. * Fix for a problem that could lead to a bogus build for people with voodoo cards. * Added Norman's jpegfactory code which can create jpeg format screen shots of a live running application. * implemented set/get_log_classes and set/get_log_priority. * Socket library improvements. * Added a C++ exception abstraction. * Property manager fixes and improvements including node path caching and debug tracing of property reads/writes. * Updates/fixes to xml handling. New in 0.0.16 * July 12, 2001 * Various changes to the property manager implimentation to better support dumping out the desired portions of the property tree to file. * Don't compile the metakit demos by default (causes problems for Irix)' * Other various tweaks for Irix. * Added a virtual destructor to XMLVisitor to fix a warning message. * Check for valid hostname lookup in sg_socket.cxx * Add a function to return modified julian date without creating an entire SGTime class. This avoids an extraneous warning about not being able to find a timezone. * Created a mailing list for cvs commit messages. * Fixed a potential array under/over run bug in interpolator.cxx * Removed all references to SGValue from the property manager. Added support for an "archive" bit in the property manager to control which values get written out. * Added SGCommandState class so that commands can compile and save copies of their arguments for efficiency if they are called multiple times. * Added Brian Baul's "tr" tiled rendering low level support library. This along with some higher level code in flightgear allows us to do ultra-hires tiled screen dumps suitable for large format printers. (Norman Vine) New in 0.0.15 * June 20, 2001 * Various bug fixes, tweaks, and optimizations. * Added a command manager (analogous to the property manager) * Better Irix Mips support. * Various gcc-3.0 fixes. * Various MSVC fixes. * Added MSVC project files (automatically generated from the unix automake configuration files.) * Removed total size limitation on interpolation table module. * Various Cygwin fixes. * Added some convenience functions to point3d. * Various compiler warning fixes. * Added a thread wrapper class (currently only supports pthreads) * Added IO routines for a lowlevel, native simgear binary 3d file format optimized for TerraGear terrain. * Better endianness checking and support for the binary file read/write routines. * Added doxygen comments for all public interface code. Documentation can be accessed via the SimGear web page. * Many FG -> SG name space changes for better consistancy throughout this package. * Added property aliases, repeated name tags, and a general xml inclusion facilities. Many other property manager clean ups following a complete rewrite. * Fixed some critical null pointer bugs in property manager. * Magnetic variation can now be fetched for any arbitrary location. New in 0.0.14 * December 14, 2000 * Added a module to manage waypoints and routes, calculate bearing and distance to next waypoint, lateral distance off route, etc. * Moved some of the basic time management code over from flightgear. * Bucket dimensions can be returned in meters * Added SOCK_STREAM (TCP) socket support to the networking code. * Updated random number generator interface so application can provide it's own seed value as well as use the default time seed. * Added a routine to calculate the distance between a point and a line segment. * Updates to the property manager and the property list loader/saver. * Added an explanation of the rational behind our terrain texture coordinate generation code. * Fixed sky dome so that the color at the horizon will always match the specified fog color. * Did a fair amount of fg -> sg name space updating (lots left to do.) * Added support for KAI C++ on linux. * MSVC tweaks. * MacOS tweaks. * FreeBSD tweaks. New in 0.0.13 * September 14, 2000 * Added support for reading and writing xml files (easyxml) * Then updates to property manager and xml code. * Update magnetic variation code. * Sky code now uses glPushAttrib and glPopAttrib so it plays better with other ssg based apps. * MacOS tweaks. * MSVC tweaks. New in 0.0.12 * July 19, 2000 * Converted project license from GPL to LGPL. * Moved low level IO (socket, file, serial) code over to SimGear. * Moved ephemeral code into simgear * Moved basic world time code into simgear * Added a property manager (registry) * Some documentation added. New in 0.0.11 * July 3, 2000 * Replaced gdbm with metakit * Added drop in sky (depends on plib) * Added spherical course and dist given two points calculations * MSVC5 fixes * Math/bucket/tiling tweaks from Norman Vine New in 0.0.7 * March 29, 2000 * Added support for RedHat package building contributed by Habibie * Added gdbm to SimGear. Many systems will already have gdbm installed so it is only built if it doesn't already exist on the user's platform. gdbm is a set of database routines that use extendible hashing and works similar to the standard UNIX dbm routines. This guarantees the availability of gdbm to any application that uses SimGear. * Optimizations and bullet proofing of magnetic variation code by Norman Vine and Ed Williams New in 0.0.6 * March 27, 2000 * Added Nima World Magnetic Model 2000 contributed by Ed Williams * Fixes for MSVC++ New in 0.0.5 * March 17, 2000 * Restructured directory layout to facilitate windows/mac IDE builds.
