68    Version 4.3.0 (9 May 2021)
69    
70      * general changes:
71        - Require at least a C++11 compliant compiler.
72        - Require some UUID generating function by underlying system.
73    
74      * src/gig.cpp, src/gig.h:
75        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
76          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
77          allow to define override LFOs' wave form (e.g. saw or square instead of
78          the default wave form which was always sine in the original
79          Gigasampler/GigaStudio software).
80        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
81          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
82          move the start point horizontally of the LFOs' waves (0° ... 360°).
83        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
84          (the original Gigasampler/GigaStudio software only had that flip phase
85          option for LFO1 and LFO2).
86        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
87          Region::UsesAnyGigFormatExtension(),
88          Instrument::UsesAnyGigFormatExtension() and
89          File::UsesAnyGigFormatExtension() (however only as private methods yet,
90          see comments on methods why).
91        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
92          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
93          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
94          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
95          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
96        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
97          (patch by Ivan Maguidhir).
98        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
99          (original patch by Ivan Maguidhir).
100        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
101          dimensions being in different order after deleting a dimension zone.
102        - Script: Generate a persistent UUID for each script.
103        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
104          accordingly added new methods to Instrument class:
105          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
106          GetScriptPatchVariable(), SetScriptPatchVariable(),
107          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
108          as child of our '3LS ' list chunk on Instrument level.
109        - Fixed undefined behaviour when modifying script slots on an instrument
110          that had been cloned and not been saved yet (e.g. unintended modification
111          of original instrument's script slots, and crash on Instrument destruction
112          due to double free of pScriptRefs).
113    
114      * src/Serialization.cpp, src/Serialization.h:
115        - Fixed broken Archive(RawData) constructor which always threw an
116          Exception.
117        - Added built-in support for C++ String objects (a.k.a. std::string
118          from the STL) and bumped Srx format version to 1.1 for that reason.
119        - Fixed assertion fault on some systems if a member variable defined was
120          serialized which was declared as size_t or ssize_t data type.
121        - Added new method Archive::operation() which allows applications to
122          distinguish between serialization vs. deserialization in their
123          serialize() method implementations.
124        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
125          the STL).
126        - Member offsets are now signed and for (newly added support of) member
127          variables on the heap -1 is always used as offset instead.
128        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
129          STL).
130        - DataType: Added optional 2nd custom type name.
131        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
132          STL).
133    
134      * src/helper.h:
135        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
136          function call.
137    
138      * src/tools/gigdump.cpp:
139        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
140          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
141          LFO2FlipPhase and LFO3FlipPhase.
142    
143    Version 4.2.0 (25 Jul 2019)
144    
145      * general changes:
146        - Added MSVC build support (anonymous patch from mailing list).
147        - Introduced CMake build support (yet constrained for building with MSVC)
148          (anonymous patch from mailing list).
149        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
150          destructors. Added new virtual method DeleteChunks() to those classes
151          for this which must be explicitly called instead to remove their RIFF
152          chunks.
153        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
154          of zero; which is unsafe per se.
155        - Added C++11 "override" keyword where appropriate.
156        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
157          of their actions when not passing a progress_t callback structure.
158    
159      * src/gig.cpp, src/gig.h:
160        - Fixed Doxygen API comments for enum types (currently latest Doxygen
161          [v1.8.13] only supports C comments in macro arguments expansion, but
162          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
163          the Doxygen source code, which currently also filter out new line
164          \n chars).
165        - Added new method File::CountSamples().
166        - Added new method File::CountInstruments().
167        - Fixed gig v4 files falsely being handled as v2 format
168          (patch by Ivan Maguidhir).
169        - Added gig v4 version identifier (File::VERSION_4).
170        - GIG FORMAT EXTENSION: Added attribute
171          DimensionRegion::SustainReleaseTrigger which allows to define whether
172          a sustain pedal up event shall cause a release trigger sample to be
173          played (default: don't play release trigger sample by sustain pedal).
174        - GIG FORMAT EXTENSION: Added attribute
175          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
176          regular behaviour of playing release trigger sample on MIDI note-off
177          events.
178        - Introduced support for writing extension files (.gx01, .gx02, ...)
179          (original patch by Ivan Maguidhir).
180        - Many gig classes derive now from DLS::Storage (see DLS changes below).
181        - Added File::GetRiffFile() method.
182    
183      * src/DLS.cpp, src/DLS.h:
184        - File: Fixed implicitly allocated RIFF::File object never been freed.
185        - Added new abstract interface base class DLS::Storage which is derived by
186          the respective classes for implementing (the old) UpdateChunks() and the
187          new DeleteChunks() method.
188        - Added File::GetRiffFile() method.
189    
190      * src/sf2.cpp, src/sf2.h:
191        - Added Sample::GetFile() method.
192        - Added File::GetRiffFile() method.
193    
194      * src/Serialization.cpp, src/Serialization.h:
195        - Hide pure internal declarations from header file to avoid numerous
196          compiler warnings when building and linking against the public API.
197        - Fixed comparision logic bug
198        - Fixed memory leak in DataType::customTypeName().
199    
200      * src/RIFF.cpp, src/RIFF.h:
201        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
202          caused a resource leak
203        - Avoid compiler warning when building for 32 bit windows.
204        - Added new method progress_t::subdivide().
205        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
206        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
207          allows a more fine graded control into which portions the subtasks are
208          divided to.
209    
210      * src/tools/gigdump.cpp:
211        - Added command line option --instrument-names which causes only
212          instrument names and their index numbers to be printed.
213    
214    Version 4.1.0 (25 Nov 2017)
215      * general changes:
216        - removed 2 GB limitation when loading a gig or DLS file
217        - using now native integer size where appropriate
218        - fixed minor issues with man pages (patch by Debian maintainer)
219        - fixed various spelling mistakes (patch by Debian maintainer)
220        - Added new "Serialization" framework (and equally named namespace)
221          which allows to serialize and deserialize native C++ objects
222          in a portable, easy and flexible way.
223        - print compiler warning if no RTTI available
224        - Fixed potential crash in command line tools gig2stereo, korg2gig,
225          korgdump and sf2extract.
226        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
227          (original patch by Paul Brossier, slightly modified).
228        - Debian: Fixed packaging error about invalid substitution variable
229          "Source-Version".
230        - Raised Debian compatibility level to Debian 9 "Stretch".
231    
232      * src/gig.cpp, src/gig.h:
233        - fixed bug in Script::SetGroup: the script chunk wasn't moved
234        - fixed compilation error with clang 3.4
235        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
236          as one single monolithic gig file. In case .gig file is >= 2GB expect a
237          large monolithic file, otherwise if .gig file is < 2 GB check for
238          "extension" files (.gx01, .gx02, ...) instead.
239        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
240          if there were dimensions after the velocity dimension: it only created
241          valid velocity tables for cases of dimensions lower than the velocity
242          dimension.
243        - added new method Sample::VerifyWaveData() which allows to check whether
244          a sample had been damaged for some reason
245        - Fix: samples' CRC checksums were damaged on file structure changes.
246        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
247        - Added new method Sample::GetWaveDataCRC32Checksum().
248        - Changed default value of EG2Release (filter release time) to 60s.
249        - Instruments' default pitch bend range is now +-2 semi tones.
250        - Fixed CRC checksums being wrong sometimes.
251        - Fix: method File::AddContentOf() did not clone script groups and scripts
252          of passed original file.
253        - Added support for serializing & deserializing DimensionRegion
254          objects (and crossfade_t and leverage_ctrl_t objects).
255        - Added enum reflection API functions for retrieving enum declaration type
256          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
257        - Exception class now has a variadic constructor which allows to add
258          textual format specifiers like with printf().
259        - On unknown leverage controller exception: show precise unknown leverage
260          controller number found.
261        - Ignore invalid leverage controller types and just show a warning on the
262          console instead of throwing an exception.
263        - Added new struct eg_opt_t and new class member variable
264          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
265          extension to the gig file format, which allows to override the default
266          behavior of the first two EGs' state machines.
267        - Fixed undefined behavior when loading a gig file with invalid
268          velocity curve parameters (fixes CVE-2017-12951).
269        - Fixed undefined behavior when loading a gig file with invalid wave
270          pool index number (fixes CVE-2017-12954).
271    
272      * src/DLS.cpp, src/DLS.h:
273        - Sample: wave pool offsets are now 64 bits (to allow support for files
274          larger than 4 GB).
275        - Exception class now has a variadic constructor which allows to add
276          textual format specifiers like with printf().
277    
278      * src/RIFF.cpp, src/RIFF.h:
279        - added support for RIFF files larger than 4 GB, by default the required
280          internal RIFF file offset size is automatically detected (that is RIFF
281          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
282          automatically use 64 bit offsets), a particular offset size can be forced
283          with a new option added to the RIFF File constructor though
284        - when saving a modified, grown RIFF file, the temporary file size during
285          Save() operation will no longer be larger than the final grown file size
286        - Exception class now has a variadic constructor which allows to add
287          textual format specifiers like with printf().
288    
289      * src/Serialization.cpp, src/Serialization.h:
290        - Archive: Added method isModified().
291        - Archive: Added method setAutoValue().
292        - Archive: Added method setIntValue().
293        - Archive: Added method setRealValue().
294        - Archive: Added method setBoolValue().
295        - Archive: Added method setEnumValue().
296        - Archive: Added method valueAsString().
297        - Archive::rawData(): Automatically re-encode new raw data stream if
298          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
299        - Object: Added method memberByUID().
300        - Object: remove() method is now protected.
301        - Archive: Added method removeMember().
302        - Archive: Added methods name() and setName().
303        - Archive: Added methods comment() and setComment().
304        - Archive: Added methods timeStampCreated(), timeStampModified(),
305          dateTimeCreated() and dateTimeModified().
306        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
307        - DataType: Implemented demangling C++ type names (for methods
308          asLongDescr() and customTypeName(bool demangle=false)).
309        - Archive::setAutoValue(): Handle human readable boolean text
310          representations like "yes", "no", "true", "false" as expected.
311        - Exception class now has a variadic constructor which allows to add
312          textual format specifiers like with printf().
313        - DataType fix: Retain backward compatibility to older versions of native
314          C++ classes/structs.
315    
316      * src/Akai.cpp:
317        - Fixed compilation error with recent, more strict compilers.
318    
319      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
320        - improved output of non-ascii characters in usage messages
321        - fixed printf format strings
322    
323      * src/tools/korg2gig.cpp:
324        - fixed c++11 narrowing warnings
325        - fixed fine tuning which was not translated at all
326    
327      * src/tools/gigdump.cpp:
328        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
329          dimension regions
330        - additionally print RIFF chunk file offset and RIFF chunk size of sample
331          data
332        - added and implemented new parameter "--verify" which allows to check
333          the raw wave form data integrity of all samples
334        - added and implemented new parameter "--rebuild-checksums" which allows
335          to recalculate the CRC32 checksum of all samples' raw wave data and
336          rebuilding the gig file's global checksum table (i.e. in case the
337          file's checksum table was damaged)
338        - print samples' CRC32 checksums
339        - Print the new EG behavior options (eg_opt_t).
340    
341      * src/tools/gigextract.cpp:
342        - Fix: if sample name contains a path separator (slash or backslash) then
343          replace them by a minus sign to avoid file system issues.
344    
345      * src/tools/gig2stereo.cpp:
346        - Also merge mono sample pairs with non matching loop information if
347          argument --incompatible was given.
348    
349      * packaging changes:
350        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
351          auto detect whether it (sh/c)ould output its messages in color.
352

385          (.KMP and .KSF files)
386    
387      * AKAI file format:
388        - Added Linux/POSIX ported version of libakai. Note that libakai is released
389          under LGPL terms while libgig is released under GPL terms. To handle this
390          license difference appropriately the AKAI support part is built as
391          separate DLL (.so file).

393          any exotic third party libraries.
394        - Fixed various compilation errors for Windows.
395        - POSIX fix: open() requires third (mode) argument if used with O_CREAT
396          (fixes #219).
397    
398      * src/gig.cpp:
399        - bugfix: VCF velocity dynamic range and VCF velocity curve
400          weren't saved correctly

429          (chunks at wrong location in the RIFF tree).
430        - Added new method Instrument::MoveTo() which allows to rearrange the order
431          of instruments within the same gig file.
432    
433      * src/DLS.cpp, src/DLS.h:
434        - added new method File::GetFileName()

456        - added new method File::IsNew()
457        - added support for loading RIFF-like files with a bit different layout
458          than "real" RIFF files (used for KORG format support)
459        - added new method Chunk::GetFile()
460        - added new method Chunk::GetLayout()
461        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

470    
471      * src/gigextract.cpp:

501          decreased sometimes also made the file corrupt!
502        - bugfix: undefined behavior (e.g. endless loop) when opening zero
503          length files, now throws a RIFF::Exception instead (fixes bug #121)
504        - bugfix: destructor for base class RIFF::Chunk accessed members
505          of derived class RIFF::File, which is bad, and caused crashes
506          when using Visual C++
507        - bugfix: files that contain zero length RIFF lists were not read
508          correctly (fixes #127) (bug was introduced 2009-03-13)
509

567          instruments
568        - write support: improved the default values for dimension region

610        - added new method File::DeleteGroupOnly() which only deletes the given
611          group but moves all its members to another group, the other method,
612          that is File::DeleteGroup() now removes not just the group, but also
613          all the samples that belong to that group
614        - fixed crash which occured on interfering File::DeleteSample() and

650          instead of the wave chunk
651        - keyswitching dimension is changed from split type "normal" to
652          "bit"
653        - real support for 24 bit samples - samples are not truncated to

704          resize and write operations in one rush
705    
706      * src/gigdump.cpp:

827        - denormals are filtered from the velocity to volume tables
828        - bugfix for dimension region switching (wrong handling of the release
829          trigger dimension, no bit range check for dimensions of split type
830          'split_type_bit')
831        - fixed panorama value in DimensionRegion (invalid conversion from
832          signed 7 bit to signed 8 bit)
