42    
43    Version 4.3.0 (9 May 2021)
44    
45      * general changes:
46        - Require at least a C++11 compliant compiler.
47        - Require some UUID generating function by underlying system.
48    
49      * src/gig.cpp, src/gig.h:
50        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
51          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
52          allow to define override LFOs' wave form (e.g. saw or square instead of
53          the default wave form which was always sine in the original
54          Gigasampler/GigaStudio software).
55        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
56          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
57          move the start point horizontally of the LFOs' waves (0° ... 360°).
58        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
59          (the original Gigasampler/GigaStudio software only had that flip phase
60          option for LFO1 and LFO2).
61        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
62          Region::UsesAnyGigFormatExtension(),
63          Instrument::UsesAnyGigFormatExtension() and
64          File::UsesAnyGigFormatExtension() (however only as private methods yet,
65          see comments on methods why).
66        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
67          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
68          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
69          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
70          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
71        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
72          (patch by Ivan Maguidhir).
73        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
74          (original patch by Ivan Maguidhir).
75        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
76          dimensions being in different order after deleting a dimension zone.
77        - Script: Generate a persistent UUID for each script.
78        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
79          accordingly added new methods to Instrument class:
80          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
81          GetScriptPatchVariable(), SetScriptPatchVariable(),
82          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
83          as child of our '3LS ' list chunk on Instrument level.
84        - Fixed undefined behaviour when modifying script slots on an instrument
85          that had been cloned and not been saved yet (e.g. unintended modification
86          of original instrument's script slots, and crash on Instrument destruction
87          due to double free of pScriptRefs).
88    
89      * src/Serialization.cpp, src/Serialization.h:
90        - Fixed broken Archive(RawData) constructor which always threw an
91          Exception.
92        - Added built-in support for C++ String objects (a.k.a. std::string
93          from the STL) and bumped Srx format version to 1.1 for that reason.
94        - Fixed assertion fault on some systems if a member variable defined was
95          serialized which was declared as size_t or ssize_t data type.
96        - Added new method Archive::operation() which allows applications to
97          distinguish between serialization vs. deserialization in their
98          serialize() method implementations.
99        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
100          the STL).
101        - Member offsets are now signed and for (newly added support of) member
102          variables on the heap -1 is always used as offset instead.
103        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
104          STL).
105        - DataType: Added optional 2nd custom type name.
106        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
107          STL).
108    
109      * src/helper.h:
110        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
111          function call.
112    
113      * src/tools/gigdump.cpp:
114        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
115          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
116          LFO2FlipPhase and LFO3FlipPhase.
117    
118    Version 4.2.0 (25 Jul 2019)
119    
120      * general changes:
121        - Added MSVC build support (anonymous patch from mailing list).
122        - Introduced CMake build support (yet constrained for building with MSVC)
123          (anonymous patch from mailing list).
124        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
125          destructors. Added new virtual method DeleteChunks() to those classes
126          for this which must be explicitly called instead to remove their RIFF
127          chunks.
128        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
129          of zero; which is unsafe per se.
130        - Added C++11 "override" keyword where appropriate.
131        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
132          of their actions when not passing a progress_t callback structure.
133    
134      * src/gig.cpp, src/gig.h:
135        - Fixed Doxygen API comments for enum types (currently latest Doxygen
136          [v1.8.13] only supports C comments in macro arguments expansion, but
137          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
138          the Doxygen source code, which currently also filter out new line
139          \n chars).
140        - Added new method File::CountSamples().
141        - Added new method File::CountInstruments().
142        - Fixed gig v4 files falsely being handled as v2 format
143          (patch by Ivan Maguidhir).
144        - Added gig v4 version identifier (File::VERSION_4).
145        - GIG FORMAT EXTENSION: Added attribute
146          DimensionRegion::SustainReleaseTrigger which allows to define whether
147          a sustain pedal up event shall cause a release trigger sample to be
148          played (default: don't play release trigger sample by sustain pedal).
149        - GIG FORMAT EXTENSION: Added attribute
150          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
151          regular behaviour of playing release trigger sample on MIDI note-off
152          events.
153        - Introduced support for writing extension files (.gx01, .gx02, ...)
154          (original patch by Ivan Maguidhir).
155        - Many gig classes derive now from DLS::Storage (see DLS changes below).
156        - Added File::GetRiffFile() method.
157    
158      * src/DLS.cpp, src/DLS.h:
159        - File: Fixed implicitly allocated RIFF::File object never been freed.
160        - Added new abstract interface base class DLS::Storage which is derived by
161          the respective classes for implementing (the old) UpdateChunks() and the
162          new DeleteChunks() method.
163        - Added File::GetRiffFile() method.
164    
165      * src/sf2.cpp, src/sf2.h:
166        - Added Sample::GetFile() method.
167        - Added File::GetRiffFile() method.
168    
169      * src/Serialization.cpp, src/Serialization.h:
170        - Hide pure internal declarations from header file to avoid numerous
171          compiler warnings when building and linking against the public API.
172        - Fixed comparision logic bug
173        - Fixed memory leak in DataType::customTypeName().
174    
175      * src/RIFF.cpp, src/RIFF.h:
176        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
177          caused a resource leak
178        - Avoid compiler warning when building for 32 bit windows.
179        - Added new method progress_t::subdivide().
180        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
181        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
182          allows a more fine graded control into which portions the subtasks are
183          divided to.
184    
185      * src/tools/gigdump.cpp:
186        - Added command line option --instrument-names which causes only
187          instrument names and their index numbers to be printed.
188    
189    Version 4.1.0 (25 Nov 2017)
190      * general changes:
191        - removed 2 GB limitation when loading a gig or DLS file
192        - using now native integer size where appropriate
193        - fixed minor issues with man pages (patch by Debian maintainer)
194        - fixed various spelling mistakes (patch by Debian maintainer)
195        - Added new "Serialization" framework (and equally named namespace)
196          which allows to serialize and deserialize native C++ objects
197          in a portable, easy and flexible way.
198        - print compiler warning if no RTTI available
199        - Fixed potential crash in command line tools gig2stereo, korg2gig,
200          korgdump and sf2extract.
201        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
202          (original patch by Paul Brossier, slightly modified).
203        - Debian: Fixed packaging error about invalid substitution variable
204          "Source-Version".
205        - Raised Debian compatibility level to Debian 9 "Stretch".
206    
207      * src/gig.cpp, src/gig.h:
208        - fixed bug in Script::SetGroup: the script chunk wasn't moved
209        - fixed compilation error with clang 3.4
210        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
211          as one single monolithic gig file. In case .gig file is >= 2GB expect a
212          large monolithic file, otherwise if .gig file is < 2 GB check for
213          "extension" files (.gx01, .gx02, ...) instead.
214        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
215          if there were dimensions after the velocity dimension: it only created
216          valid velocity tables for cases of dimensions lower than the velocity
217          dimension.
218        - added new method Sample::VerifyWaveData() which allows to check whether
219          a sample had been damaged for some reason
220        - Fix: samples' CRC checksums were damaged on file structure changes.
221        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
222        - Added new method Sample::GetWaveDataCRC32Checksum().
223        - Changed default value of EG2Release (filter release time) to 60s.
224        - Instruments' default pitch bend range is now +-2 semi tones.
225        - Fixed CRC checksums being wrong sometimes.
226        - Fix: method File::AddContentOf() did not clone script groups and scripts
227          of passed original file.
228        - Added support for serializing & deserializing DimensionRegion
229          objects (and crossfade_t and leverage_ctrl_t objects).
230        - Added enum reflection API functions for retrieving enum declaration type
231          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
232        - Exception class now has a variadic constructor which allows to add
233          textual format specifiers like with printf().
234        - On unknown leverage controller exception: show precise unknown leverage
235          controller number found.
236        - Ignore invalid leverage controller types and just show a warning on the
237          console instead of throwing an exception.
238        - Added new struct eg_opt_t and new class member variable
239          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
240          extension to the gig file format, which allows to override the default
241          behavior of the first two EGs' state machines.
242        - Fixed undefined behavior when loading a gig file with invalid
243          velocity curve parameters (fixes CVE-2017-12951).
244        - Fixed undefined behavior when loading a gig file with invalid wave
245          pool index number (fixes CVE-2017-12954).
246    
247      * src/DLS.cpp, src/DLS.h:
248        - Sample: wave pool offsets are now 64 bits (to allow support for files
249          larger than 4 GB).
250        - Exception class now has a variadic constructor which allows to add
251          textual format specifiers like with printf().
252    
253      * src/RIFF.cpp, src/RIFF.h:
254        - added support for RIFF files larger than 4 GB, by default the required
255          internal RIFF file offset size is automatically detected (that is RIFF
256          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
257          automatically use 64 bit offsets), a particular offset size can be forced
258          with a new option added to the RIFF File constructor though
259        - when saving a modified, grown RIFF file, the temporary file size during
260          Save() operation will no longer be larger than the final grown file size
261        - Exception class now has a variadic constructor which allows to add
262          textual format specifiers like with printf().
263    
264      * src/Serialization.cpp, src/Serialization.h:
265        - Archive: Added method isModified().
266        - Archive: Added method setAutoValue().
267        - Archive: Added method setIntValue().
268        - Archive: Added method setRealValue().
269        - Archive: Added method setBoolValue().
270        - Archive: Added method setEnumValue().
271        - Archive: Added method valueAsString().
272        - Archive::rawData(): Automatically re-encode new raw data stream if
273          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
274        - Object: Added method memberByUID().
275        - Object: remove() method is now protected.
276        - Archive: Added method removeMember().
277        - Archive: Added methods name() and setName().
278        - Archive: Added methods comment() and setComment().
279        - Archive: Added methods timeStampCreated(), timeStampModified(),
280          dateTimeCreated() and dateTimeModified().
281        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
282        - DataType: Implemented demangling C++ type names (for methods
283          asLongDescr() and customTypeName(bool demangle=false)).
284        - Archive::setAutoValue(): Handle human readable boolean text
285          representations like "yes", "no", "true", "false" as expected.
286        - Exception class now has a variadic constructor which allows to add
287          textual format specifiers like with printf().
288        - DataType fix: Retain backward compatibility to older versions of native
289          C++ classes/structs.
290    
291      * src/Akai.cpp:
292        - Fixed compilation error with recent, more strict compilers.
293    
294      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:

297    
298      * src/tools/korg2gig.cpp:
299        - fixed c++11 narrowing warnings
300        - fixed fine tuning which was not translated at all
301    
302      * src/tools/gigdump.cpp:
303        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
304          dimension regions
305        - additionally print RIFF chunk file offset and RIFF chunk size of sample
306          data
307        - added and implemented new parameter "--verify" which allows to check
308          the raw wave form data integrity of all samples
309        - added and implemented new parameter "--rebuild-checksums" which allows
310          to recalculate the CRC32 checksum of all samples' raw wave data and
311          rebuilding the gig file's global checksum table (i.e. in case the
312          file's checksum table was damaged)
313        - print samples' CRC32 checksums
314        - Print the new EG behavior options (eg_opt_t).
315    
316      * src/tools/gigextract.cpp:
317        - Fix: if sample name contains a path separator (slash or backslash) then
318          replace them by a minus sign to avoid file system issues.
319    
320      * src/tools/gig2stereo.cpp:
321        - Also merge mono sample pairs with non matching loop information if
322          argument --incompatible was given.
323    
324      * packaging changes:
325        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
326          auto detect whether it (sh/c)ould output its messages in color.
327    
328    Version 4.0.0 (14 Jul 2015)
329      * general changes:
330        - minor Makefile fix for parallel make

341        - moved source files of command line tools to new subdir src/tools
342        - libgig.so and libakai.so files are now installed under
343          $(prefix)/lib/libgig/ by default.
344        - Header files are now installed under $(prefix)/include/libgig/ by default.
345        - Fixed various packaging issues regarding installation directories
346          (fixes #218).
347        - added new command line tool "gig2stereo" (and a man page for it)

351    
352      * SoundFont file format:
353        - initial implementation
354        - changed region lookup API to avoid malloc in RT threads
355        - fixed GetEG1Sustain which didn't return correct value
356        - bugfix: GetPan always returned -1, 0 or 1
357    
358      * KORG file format:
359        - initial support for sample based instruments in KORG's file format
360          (.KMP and .KSF files)
361    
362      * AKAI file format:
363        - Added Linux/POSIX ported version of libakai. Note that libakai is released
364          under LGPL terms while libgig is released under GPL terms. To handle this
365          license difference appropriately the AKAI support part is built as
366          separate DLL (.so file).

378          saved
379        - added write support for CtrlTrigger midi rule
380        - added read and write support for Legato and Alternator midi
381          rules
382        - bugfix: sample groups were sometimes created multiple times or with
383          wrong textual group name
384        - added new method File::AddContentOf() for merging .gig files
385        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
386          controller types (only works with LinuxSampler & gigedit, will not
387          work with Gigasampler/GigaStudio)
388        - added new method File::GetGroup(String name) for getting group by name
389        - added new method Region::GetDimensionDefinition(dimension_t type)
390        - bugfix: don't alter region pointer in DimensionRegion::CopyAssign()
391        - added some more sanity checks in Region::AddDimension()
392        - added new method Region::DeleteDimensionZone(dimension_t, int)
393        - added new method Region::SplitDimensionZone(dimension_t, int)
394        - Fixed crash caused by Region::GetDimensionRegionByValue() that happened
395          with certain velocity split sounds under certain conditions (added bound
396          constraints to prevent that)
397        - GIG FORMAT EXTENSION: added support for real-time instrument scripts.
398        - added new method Region::GetDimensionRegionIndexByValue()
399        - added new method Script::GetGroup()
400        - added new method Region::SetDimensionType()
401        - Added support for custom progress notification while saving to gig file.
402        - Bugfix: Adding a new region in between two existing regions caused the
403          new one being dropped after save operation and the gig file being tainted
404          (chunks at wrong location in the RIFF tree).
405        - Added new method Instrument::MoveTo() which allows to rearrange the order
406          of instruments within the same gig file.
407    
408      * src/DLS.cpp, src/DLS.h:
409        - added new method File::GetFileName()
410        - fixed minor "memory leak on exception" bug found with cppcheck
411        - added new method File::GetExtensionFile(int index)
412        - added new method File::SetFileName() allowing to call File::Save()
413          later on without passing a file name
414        - added inline helper methods overlaps() for struct range_t
415        - Added support for custom progress notification while saving to DLS file.
416        - Bugfix: Adding a new region in between two existing regions caused the
417          new one being dropped after save operation and the gig file being tainted
418          (chunks at wrong location in the RIFF tree).
419    
420      * src/SF.cpp, src/SF.h:
421        - added new method Sample::ReadNoClear()
422    
423      * src/RIFF.cpp, src/RIFF.h:
424        - bugfix: avoid calling read() with count 0 when writing a file,
425          as this may hang on some systems
426        - fixed memory leak and memory handling errors when file loading
427          fails
428        - added new method Chunk::ReadString
429        - added new method File::SetFileName() allowing to call File::Save()
430          later on without passing a file name
431        - added new method File::IsNew()
432        - added support for loading RIFF-like files with a bit different layout
433          than "real" RIFF files (used for KORG format support)
434        - added new method Chunk::GetFile()
435        - added new method Chunk::GetLayout()
436        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
437          allows to move a subchunk within the current List, whereas the new 2nd
438          one allows to move the subchunk from the current list to another list
439        - POSIX: only assume -1 result value as error on open() calls
440        - POSIX: show operating system's error reason if opening a file failed
441        - Added support for custom progress notification while saving to RIFF file.
442        - Fixed embarrassing old bug: POSIX read() errors were never detected on
443          Chunk::Read() calls due to signment incompatible variable.
444        - Cleanup of an old DLL binary backward compatibility hack.
445    
446      * src/gigextract.cpp:
447        - export sample loop, unity note and fine tune with libsndfile
448    
449      * src/riftree.cpp:
450        - added more command line options for being able to also dump other kind
451          of file formats similar but not equal to the RIFF format
