21 - fixed memory leak and memory handling errors when file loading
22 fails
23
24 Version 3.3.0 (30 Jul 2009)
25
26 * general changes:
27 - fixed compilation with gcc 4.3
28 - fixes for building with Visual C++
29 - minor fix in configure for building DLL on Windows
30
31 * src/gig.cpp, src/gig.h:
32 - added partial support for MIDI rules, only the Controller
33 Triggered rule is supported so far
34 - bugfix: removed another iterator invalidation in DeleteSample
35 - bugfix in Sample::LoadSampleData*(): reset sample read position to
36 sample start before trying to (re)load sample data from file (#82)
37 - bugfix: EG3 depth parameter was not saved correctly
38 - fixed crash which occured when streaming a gig sample with
39 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
40

42 - bugfix: saving to the same file after the file size had been
43 increased made the file corrupt (#82)
44 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
45 is not written physically yet (#82)
46 - bugfix: saving to the same file after the file size had been
47 decreased sometimes also made the file corrupt!
48 - bugfix: undefined behavior (e.g. endless loop) when opening zero
49 length files, now throws a RIFF::Exception instead (fixes bug #121)

51 of derived class RIFF::File, which is bad, and caused crashes
52 when using Visual C++
53 - bugfix: files that contain zero length RIFF lists were not read
54 correctly (fixes #127) (bug was introduced 2009-03-13)
55
56 Version 3.2.1 (5 Dec 2007)

66
67 Version 3.2.0 (14 Oct 2007)
68
69 * packaging changes:

79 - improved handling of fixed length info strings - separate default
80 lengths can be specified for each INFO chunk
81 - added Resource::GenerateDLSID function

95 - added missing parameter initalizations in sample, region and
96 instrument constructors
97 - clear unused fields when saving samples and regions
98 - fixed write support bugs: v3 dimension limits and chunksize
99 weren't saved, leverage controller of type controlchange
100 couldn't be saved, group name list chunk was placed wrong,
101 dimension region chunks also placed wrong
102 - added initialization of some fixed info strings in file and
103 instrument
104 - write support: files created by libgig will now have the RIFF
105 chunks in correct order
106 - write support: two previously unknown fields in dimension
107 definition are now saved
108 - added constants for gig file versions

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

152 - custom velocity splits now works for gig v3 files too
153 - added support for custom splits points for other dimensions than
154 velocity (gig v3 feature)
155 - added "smart midi" and "round robin keyboard" dimensions
156 - added new method File::DeleteGroupOnly() which only deletes the given
157 group but moves all its members to another group, the other method,
158 that is File::DeleteGroup() now removes not just the group, but also
159 all the samples that belong to that group
160 - fixed crash which occured on interfering File::DeleteSample() and
161 File::GetNextSample() calls (due to iterator invalidation)
162 - fixed group names which were not saved

164 with the group
165 - added Instrument::MoveRegion method
166 - fixed constructor for Region, which did not initialize correctly
167 when used from Instrument::AddRegion
168 - when saving, override the gig::Regions sample reference simply by
169 the region's first dimension region's sample (avoids an exception
170 when trying to save a new instrument)
171 - fixed AddDimension() method which did not fill out all mandatory
172 dimension definition fields
173
174 * src/DLS.cpp, src/DLS.h:

308 (patch by Andreas Persson)
309 - added some file format compatibility checks
310 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

365 SuSE and Fedora)
366 - fixed generation of Doxygen API documentation (now also included in
367 RPM and Debian packages)
368
369 * src/gig.cpp, src/gig.h:
370 - fixed / improved accuracy of all three velocity to volume
371 transformation functions a.k.a. 'nonlinear','linear','special'
372 (patch by Andreas Persson)
373 - denormals are filtered from the velocity to volume tables
374 - bugfix for dimension region switching (wrong handling of the release

397 - added libgig.spec and libgig.pc package configurations for generating
398 Redhat packages
399 - header files included on installation.
400 - autotools-generated files removed from CVS repository.
401 - added support for generating Debian packages
402 - version of shared library can be set in configure.in
403
404 Version 0.7.0 (3 May 2004)
405
406 * general changes:
407 - various big endian specific corrections
408 (successfully tested now on PPC)
409 - minor adjustments to avoid compile errors on some systems
410 (using now pow() instead of powl() and --pedantic g++ compiler switch)
411 - libtoolized the library
412 - added man pages for the command line tools
413 (gigextract, gigdump, dlsdump, rifftree)
414
415 * src/gig.cpp, src/gig.h:
416 - fixed bug in decompression algorithm which caused it not to detect
417 the end of a stream
418 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
419 takes the MIDI key velocity value as an argument and returns the
420 appropriate volume factor (0.0 ... 1.0) for the sample to be played
421 back, the velocity curve transformation functions used for this are
422 only an approximation so far
423 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
424 'Sample::LoopSize' which reflected wrong values
425 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
426 measured in sample points instead of byte offset
427 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
428 'Sample::FineTune'
429 - added class attribute 'Sample::LoopSize'
430 - added method GetInstrument(uint index) to class 'File'
431 - added ReadAndLoop() method to class 'Sample' which is an extension to
432 the normal Read() method to honor the sample's looping information
433 while streaming from disk
434 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
435 'eg2_ctrl_t': replaced this huge enumeration by a structure which
436 reflects the MIDI controller number in case of an ordinary control
437 change controller (this saves a huge switch-case block in the
438 application of the library user)
439 - renamed following attributes in class 'DimensionRegion':
440 'AttenuationContol' -> 'AttenuationController',
441 'InvertAttenuationControl' -> 'InvertAttenuationController',
442 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
443 - minor fix in API documentation for method GetVelocityAttenuation() in
444 class 'DimensionRegion'
445
446 * src/RIFF.cpp, src/RIFF.h:
447 - added additional API documentation
448 - minor fix in Chunk::Read() method (only a minor efficiency issue)
449
450 * src/gigdump.cpp:
451 - added printout of samples' looping informations
452
453 Version 0.6.0 (3 Nov 2003)
454
455 * initial release
