20        - Mac OS X: link with CoreFoundation (for the UUID function)
21        - removed gcc 4.7 warnings
22        - modernized configure script
23        - removed usage of deprecated Automake variable INCLUDES
24        - added new command line tool "gigmerge"
25        - added "const" keyword to several methods
26        - added new command line tool "gig2mono"
27        - added man page for "sf2dump"
28        - added new command line tool "korgdump" (and a man page for it)

30        - moved source files of command line tools to new subdir src/tools
31        - libgig.so and libakai.so files are now installed under
32          $(prefix)/lib/libgig/ by default.
33        - Header files are now installed under $(prefix)/include/libgig/ by default.
34        - Fixed various packaging issues regarding installation directories
35          (fixes #218).

93          (chunks at wrong location in the RIFF tree).
94        - Added new method Instrument::MoveTo() which allows to rearrange the order
95          of instruments within the same gig file.
96    
97      * src/DLS.cpp, src/DLS.h:
98        - added new method File::GetFileName()

103        - added inline helper methods overlaps() for struct range_t
104        - Added support for custom progress notification while saving to DLS file.
105        - Bugfix: Adding a new region in between two existing regions caused the

119          later on without passing a file name
120        - added new method File::IsNew()
121        - added support for loading RIFF-like files with a bit different layout

123        - added new method Chunk::GetFile()
124        - added new method Chunk::GetLayout()
125        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

127          one allows to move the subchunk from the current list to another list
128        - POSIX: only assume -1 result value as error on open() calls
129        - POSIX: show operating system's error reason if opening a file failed
130        - Added support for custom progress notification while saving to RIFF file.
131        - Fixed embarrassing old bug: POSIX read() errors were never detected on

133        - Cleanup of an old DLL binary backward compatibility hack.
134    
135      * src/gigextract.cpp:

151          Triggered rule is supported so far
152        - bugfix: removed another iterator invalidation in DeleteSample
153        - bugfix in Sample::LoadSampleData*(): reset sample read position to
154          sample start before trying to (re)load sample data from file (#82)

158    
159      * src/RIFF.cpp, src/RIFF.h:
160        - bugfix: saving to the same file after the file size had been
161          increased made the file corrupt (#82)
162        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
163          is not written physically yet (#82)
164        - bugfix: saving to the same file after the file size had been
165          decreased sometimes also made the file corrupt!
166        - bugfix: undefined behavior (e.g. endless loop) when opening zero
167          length files, now throws a RIFF::Exception instead (fixes bug #121)
168        - bugfix: destructor for base class RIFF::Chunk accessed members
169          of derived class RIFF::File, which is bad, and caused crashes
170          when using Visual C++
171        - bugfix: files that contain zero length RIFF lists were not read
172          correctly (fixes #127) (bug was introduced 2009-03-13)
173    
174    Version 3.2.1 (5 Dec 2007)
175    
176      * src/RIFF.cpp, src/RIFF.h:
177        - avoid Windows to perform unnecessary file stream caching which would
178          decrease disk streaming performance on Windows systems otherwise

209          happened when gig::Group informations were accessed before
210        - fixed write support for big-endian systems

226        - added constants for gig file versions
227        - write support: the 3crc and einf chunks are now created or
228          updated when a file is saved (3crc contains sample checksums,
229          einf contains file statistics)
230        - write support: DLSID is now generated on the file and the
231          instruments
232        - write support: improved the default values for dimension region
233          parameters
234        - more write support fixes: crossfade parameters were not saved,

237          not saved correctly
238        - write support: 24 bit samples can now be written
239        - write support: version 3 is now the default for new files

244        - DeleteSample now removes all references to the deleted sample
245        - AddDimension now copies all parameters from existing dimension
246          regions and also makes sure that the samplechannel dimension is
247          placed first in the list of dimensions.
248        - added method GetParent() to class 'DimensionRegion', which returns its
249          parent Region
250        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
251          unused areas
252        - added various setter methods to DimensionRegion class which take care
253          of updating lookup tables / caches.
254    
255      * src/RIFF.cpp, src/RIFF.h:
256        - added File::SetByteOrder method
257        - Windows fix: saving a new file didn't work

269      * src/gig.cpp, src/gig.h:
270        - custom velocity splits now works for gig v3 files too
271        - added support for custom splits points for other dimensions than
272          velocity (gig v3 feature)
273        - added "smart midi" and "round robin keyboard" dimensions
274        - added new method File::DeleteGroupOnly() which only deletes the given
275          group but moves all its members to another group, the other method,
276          that is File::DeleteGroup() now removes not just the group, but also
277          all the samples that belong to that group
278        - fixed crash which occured on interfering File::DeleteSample() and
279          File::GetNextSample() calls (due to iterator invalidation)

285          when used from Instrument::AddRegion
286        - when saving, override the gig::Regions sample reference simply by
287          the region's first dimension region's sample (avoids an exception

312          pedal up and pedal down)
313        - sample loop parameters are now taken from the DimensionRegion
314          instead of the wave chunk
315        - keyswitching dimension is changed from split type "normal" to
316          "bit"
317        - real support for 24 bit samples - samples are not truncated to

350    
351      * src/gig.cpp, src/gig.h:

368          resize and write operations in one rush
369    
370      * src/gigdump.cpp:
