36 - fixes for building with Visual C++
37 - minor fix in configure for building DLL on Windows

103 - added missing parameter initalizations in sample, region and
104 instrument constructors
105 - clear unused fields when saving samples and regions
106 - fixed write support bugs: v3 dimension limits and chunksize
107 weren't saved, leverage controller of type controlchange
108 couldn't be saved, group name list chunk was placed wrong,
109 dimension region chunks also placed wrong
110 - added initialization of some fixed info strings in file and
111 instrument
112 - write support: files created by libgig will now have the RIFF
113 chunks in correct order

121 instruments
122 - write support: improved the default values for dimension region
123 parameters
124 - more write support fixes: crossfade parameters were not saved,
125 v3 dimension limits were not correctly initialized and saved
126 when dimensions were added or deleted, v3 wave pool offsets were
127 not saved correctly
128 - write support: 24 bit samples can now be written
129 - write support: version 3 is now the default for new files
130 - more write support fixes: the 3ewg chunk is now bigger for v3,
131 dimension regions without mapped samples are now allowed, 3gnl
132 list in v3 files now always has 128 entries, several parameters
133 where incorrectly saved due to an operator precedence mistake
134 - DeleteSample now removes all references to the deleted sample
135 - AddDimension now copies all parameters from existing dimension
136 regions and also makes sure that the samplechannel dimension is
137 placed first in the list of dimensions.
138 - added method GetParent() to class 'DimensionRegion', which returns its
139 parent Region
140 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
141 unused areas
142 - added various setter methods to DimensionRegion class which take care
143 of updating lookup tables / caches.

161 - added support for custom splits points for other dimensions than
162 velocity (gig v3 feature)
163 - added "smart midi" and "round robin keyboard" dimensions
164 - added new method File::DeleteGroupOnly() which only deletes the given
165 group but moves all its members to another group, the other method,
166 that is File::DeleteGroup() now removes not just the group, but also
167 all the samples that belong to that group
168 - fixed crash which occured on interfering File::DeleteSample() and
169 File::GetNextSample() calls (due to iterator invalidation)
170 - fixed group names which were not saved

172 with the group
173 - added Instrument::MoveRegion method
174 - fixed constructor for Region, which did not initialize correctly
175 when used from Instrument::AddRegion
176 - when saving, override the gig::Regions sample reference simply by
177 the region's first dimension region's sample (avoids an exception
178 when trying to save a new instrument)

180 dimension definition fields
181
182 * src/DLS.cpp, src/DLS.h:

315 articulation informations are ignored at the moment
316 (patch by Andreas Persson)
317 - added some file format compatibility checks
318 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

373 SuSE and Fedora)
374 - fixed generation of Doxygen API documentation (now also included in
375 RPM and Debian packages)
376
377 * src/gig.cpp, src/gig.h:
378 - fixed / improved accuracy of all three velocity to volume
379 transformation functions a.k.a. 'nonlinear','linear','special'
380 (patch by Andreas Persson)
381 - denormals are filtered from the velocity to volume tables
382 - bugfix for dimension region switching (wrong handling of the release

410 - version of shared library can be set in configure.in
411
412 Version 0.7.0 (3 May 2004)
413
414 * general changes:
415 - various big endian specific corrections
416 (successfully tested now on PPC)
417 - minor adjustments to avoid compile errors on some systems
418 (using now pow() instead of powl() and --pedantic g++ compiler switch)
419 - libtoolized the library
420 - added man pages for the command line tools
421 (gigextract, gigdump, dlsdump, rifftree)
422
423 * src/gig.cpp, src/gig.h:
424 - fixed bug in decompression algorithm which caused it not to detect
425 the end of a stream
426 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
427 takes the MIDI key velocity value as an argument and returns the
428 appropriate volume factor (0.0 ... 1.0) for the sample to be played
429 back, the velocity curve transformation functions used for this are
430 only an approximation so far
431 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
432 'Sample::LoopSize' which reflected wrong values
433 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
434 measured in sample points instead of byte offset
435 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
436 'Sample::FineTune'
437 - added class attribute 'Sample::LoopSize'
438 - added method GetInstrument(uint index) to class 'File'
439 - added ReadAndLoop() method to class 'Sample' which is an extension to
440 the normal Read() method to honor the sample's looping information
441 while streaming from disk
442 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
443 'eg2_ctrl_t': replaced this huge enumeration by a structure which
444 reflects the MIDI controller number in case of an ordinary control
445 change controller (this saves a huge switch-case block in the
446 application of the library user)
447 - renamed following attributes in class 'DimensionRegion':
448 'AttenuationContol' -> 'AttenuationController',
449 'InvertAttenuationControl' -> 'InvertAttenuationController',
450 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
451 - minor fix in API documentation for method GetVelocityAttenuation() in
452 class 'DimensionRegion'
453
454 * src/RIFF.cpp, src/RIFF.h:
455 - added additional API documentation
456 - minor fix in Chunk::Read() method (only a minor efficiency issue)
457
458 * src/gigdump.cpp:
459 - added printout of samples' looping informations
460
461 Version 0.6.0 (3 Nov 2003)
462
463 * initial release
