1 Version SVN trunk (?)
2
3 * src/Serialization.cpp, src/Serialization.h:
4 - Hide pure internal declarations from header file to avoid numerous
5 compiler warnings when building and linking against the public API.
6
7 Version 4.1.0 (25 Nov 2017)
8 * general changes:
9 - removed 2 GB limitation when loading a gig or DLS file
10 - using now native integer size where appropriate
11 - fixed minor issues with man pages (patch by Debian maintainer)
12 - fixed various spelling mistakes (patch by Debian maintainer)
13 - Added new "Serialization" framework (and equally named namespace)
14 which allows to serialize and deserialize native C++ objects
15 in a portable, easy and flexible way.
16 - print compiler warning if no RTTI available
17 - Fixed potential crash in command line tools gig2stereo, korg2gig,
18 korgdump and sf2extract.
19 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
20 (original patch by Paul Brossier, slightly modified).
21 - Debian: Fixed packaging error about invalid substitution variable
22 "Source-Version".
23 - Raised Debian compatibility level to Debian 9 "Stretch".
24
25 * src/gig.cpp, src/gig.h:
26 - fixed bug in Script::SetGroup: the script chunk wasn't moved
27 - fixed compilation error with clang 3.4
28 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
29 as one single monolithic gig file. In case .gig file is >= 2GB expect a
30 large monolithic file, otherwise if .gig file is < 2 GB check for
31 "extension" files (.gx01, .gx02, ...) instead.
32 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
33 if there were dimensions after the velocity dimension: it only created
34 valid velocity tables for cases of dimensions lower than the velocity
35 dimension.
36 - added new method Sample::VerifyWaveData() which allows to check whether
37 a sample had been damaged for some reason
38 - Fix: samples' CRC checksums were damaged on file structure changes.
39 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
40 - Added new method Sample::GetWaveDataCRC32Checksum().
41 - Changed default value of EG2Release (filter release time) to 60s.
42 - Instruments' default pitch bend range is now +-2 semi tones.
43 - Fixed CRC checksums being wrong sometimes.
44 - Fix: method File::AddContentOf() did not clone script groups and scripts
45 of passed original file.
46 - Added support for serializing & deserializing DimensionRegion
47 objects (and crossfade_t and leverage_ctrl_t objects).
48 - Added enum reflection API functions for retrieving enum declaration type
49 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
50 - Exception class now has a variadic constructor which allows to add
51 textual format specifiers like with printf().
52 - On unknown leverage controller exception: show precise unknown leverage
53 controller number found.
54 - Ignore invalid leverage controller types and just show a warning on the
55 console instead of throwing an exception.
56 - Added new struct eg_opt_t and new class member variable
57 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
58 extension to the gig file format, which allows to override the default
59 behavior of the first two EGs' state machines.
60 - Fixed undefined behavior when loading a gig file with invalid
61 velocity curve parameters (fixes CVE-2017-12951).
62 - Fixed undefined behavior when loading a gig file with invalid wave
63 pool index number (fixes CVE-2017-12954).
64
65 * src/DLS.cpp, src/DLS.h:
66 - Sample: wave pool offsets are now 64 bits (to allow support for files
67 larger than 4 GB).
68 - Exception class now has a variadic constructor which allows to add
69 textual format specifiers like with printf().
70
71 * src/RIFF.cpp, src/RIFF.h:
72 - added support for RIFF files larger than 4 GB, by default the required
73 internal RIFF file offset size is automatically detected (that is RIFF
74 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
75 automatically use 64 bit offsets), a particular offset size can be forced
76 with a new option added to the RIFF File constructor though
77 - when saving a modified, grown RIFF file, the temporary file size during
78 Save() operation will no longer be larger than the final grown file size
79 - Exception class now has a variadic constructor which allows to add
80 textual format specifiers like with printf().
81
82 * src/Serialization.cpp, src/Serialization.h:
83 - Archive: Added method isModified().
84 - Archive: Added method setAutoValue().
85 - Archive: Added method setIntValue().
86 - Archive: Added method setRealValue().
87 - Archive: Added method setBoolValue().
88 - Archive: Added method setEnumValue().
89 - Archive: Added method valueAsString().
90 - Archive::rawData(): Automatically re-encode new raw data stream if
91 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
92 - Object: Added method memberByUID().
93 - Object: remove() method is now protected.
94 - Archive: Added method removeMember().
95 - Archive: Added methods name() and setName().
96 - Archive: Added methods comment() and setComment().
97 - Archive: Added methods timeStampCreated(), timeStampModified(),
98 dateTimeCreated() and dateTimeModified().
99 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
100 - DataType: Implemented demangling C++ type names (for methods
101 asLongDescr() and customTypeName(bool demangle=false)).
102 - Archive::setAutoValue(): Handle human readable boolean text
103 representations like "yes", "no", "true", "false" as expected.
104 - Exception class now has a variadic constructor which allows to add
105 textual format specifiers like with printf().
106 - DataType fix: Retain backward compatibility to older versions of native
107 C++ classes/structs.
108

124 data
125 - added and implemented new parameter "--verify" which allows to check
126 the raw wave form data integrity of all samples
127 - added and implemented new parameter "--rebuild-checksums" which allows
128 to recalculate the CRC32 checksum of all samples' raw wave data and
129 rebuilding the gig file's global checksum table (i.e. in case the
130 file's checksum table was damaged)
131 - print samples' CRC32 checksums
132 - Print the new EG behavior options (eg_opt_t).
133
134 * src/tools/gigextract.cpp:
135 - Fix: if sample name contains a path separator (slash or backslash) then
136 replace them by a minus sign to avoid file system issues.
137
138 * src/tools/gig2stereo.cpp:
139 - Also merge mono sample pairs with non matching loop information if
140 argument --incompatible was given.

256 one allows to move the subchunk from the current list to another list
257 - POSIX: only assume -1 result value as error on open() calls
258 - POSIX: show operating system's error reason if opening a file failed

285 - fixed crash which occured when streaming a gig sample with
286 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
287
288 * src/RIFF.cpp, src/RIFF.h:
289 - bugfix: saving to the same file after the file size had been
290 increased made the file corrupt (#82)
291 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
292 is not written physically yet (#82)

359 - write support: DLSID is now generated on the file and the
360 instruments
361 - write support: improved the default values for dimension region
362 parameters

400 - added support for custom splits points for other dimensions than
401 velocity (gig v3 feature)
402 - added "smart midi" and "round robin keyboard" dimensions
403 - added new method File::DeleteGroupOnly() which only deletes the given
404 group but moves all its members to another group, the other method,
405 that is File::DeleteGroup() now removes not just the group, but also
406 all the samples that belong to that group
407 - fixed crash which occured on interfering File::DeleteSample() and
408 File::GetNextSample() calls (due to iterator invalidation)

554 articulation informations are ignored at the moment
555 (patch by Andreas Persson)
556 - added some file format compatibility checks
557 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
558 never used, because the necessary check was made before

607
608 * packaging changes:
609 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
610 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
611 - fixed man pages automake install rule (which didn't work on Mandrake,
612 SuSE and Fedora)
613 - fixed generation of Doxygen API documentation (now also included in
614 RPM and Debian packages)
615
616 * src/gig.cpp, src/gig.h:
617 - fixed / improved accuracy of all three velocity to volume
618 transformation functions a.k.a. 'nonlinear','linear','special'
619 (patch by Andreas Persson)
620 - denormals are filtered from the velocity to volume tables
621 - bugfix for dimension region switching (wrong handling of the release
622 trigger dimension, no bit range check for dimensions of split type
623 'split_type_bit')
624 - fixed panorama value in DimensionRegion (invalid conversion from
625 signed 7 bit to signed 8 bit)
626 - added class attribute 'Layers' to class 'gig::Region'
627 - symbol prototyping of gig::Region (fixes build failure with qsampler)
628

639 Gigasampler layers
640
641 Version 0.7.1 (2 Jul 2004)
642
643 * packaging changes:
644 - added libgig.spec and libgig.pc package configurations for generating
645 Redhat packages
646 - header files included on installation.
647 - autotools-generated files removed from CVS repository.
648 - added support for generating Debian packages
649 - version of shared library can be set in configure.in
650
651 Version 0.7.0 (3 May 2004)
652
653 * general changes:
654 - various big endian specific corrections
655 (successfully tested now on PPC)
656 - minor adjustments to avoid compile errors on some systems
657 (using now pow() instead of powl() and --pedantic g++ compiler switch)
658 - libtoolized the library
659 - added man pages for the command line tools
660 (gigextract, gigdump, dlsdump, rifftree)
661
662 * src/gig.cpp, src/gig.h:
663 - fixed bug in decompression algorithm which caused it not to detect
664 the end of a stream
665 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
666 takes the MIDI key velocity value as an argument and returns the
667 appropriate volume factor (0.0 ... 1.0) for the sample to be played
668 back, the velocity curve transformation functions used for this are
669 only an approximation so far
670 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
671 'Sample::LoopSize' which reflected wrong values
672 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
673 measured in sample points instead of byte offset
674 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
675 'Sample::FineTune'
676 - added class attribute 'Sample::LoopSize'
677 - added method GetInstrument(uint index) to class 'File'
678 - added ReadAndLoop() method to class 'Sample' which is an extension to
679 the normal Read() method to honor the sample's looping information
680 while streaming from disk
681 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
682 'eg2_ctrl_t': replaced this huge enumeration by a structure which
683 reflects the MIDI controller number in case of an ordinary control
684 change controller (this saves a huge switch-case block in the
685 application of the library user)
686 - renamed following attributes in class 'DimensionRegion':
687 'AttenuationContol' -> 'AttenuationController',
688 'InvertAttenuationControl' -> 'InvertAttenuationController',
689 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
690 - minor fix in API documentation for method GetVelocityAttenuation() in
691 class 'DimensionRegion'
692
693 * src/RIFF.cpp, src/RIFF.h:
694 - added additional API documentation
695 - minor fix in Chunk::Read() method (only a minor efficiency issue)
696
697 * src/gigdump.cpp:
698 - added printout of samples' looping informations
699
700 Version 0.6.0 (3 Nov 2003)
701
702 * initial release
