116    
117    Version 4.3.0 (9 May 2021)
118    
119      * general changes:
120        - Require at least a C++11 compliant compiler.
121        - Require some UUID generating function by underlying system.
122    
123      * src/gig.cpp, src/gig.h:
124        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
125          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
126          allow to define override LFOs' wave form (e.g. saw or square instead of
127          the default wave form which was always sine in the original
128          Gigasampler/GigaStudio software).
129        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
130          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
131          move the start point horizontally of the LFOs' waves (0° ... 360°).
132        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
133          (the original Gigasampler/GigaStudio software only had that flip phase
134          option for LFO1 and LFO2).
135        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
136          Region::UsesAnyGigFormatExtension(),
137          Instrument::UsesAnyGigFormatExtension() and
138          File::UsesAnyGigFormatExtension() (however only as private methods yet,
139          see comments on methods why).
140        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
141          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
142          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
143          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
144          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
145        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
146          (patch by Ivan Maguidhir).
147        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
148          (original patch by Ivan Maguidhir).
149        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
150          dimensions being in different order after deleting a dimension zone.
151        - Script: Generate a persistent UUID for each script.
152        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
153          accordingly added new methods to Instrument class:
154          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
155          GetScriptPatchVariable(), SetScriptPatchVariable(),
156          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
157          as child of our '3LS ' list chunk on Instrument level.
158        - Fixed undefined behaviour when modifying script slots on an instrument
159          that had been cloned and not been saved yet (e.g. unintended modification
160          of original instrument's script slots, and crash on Instrument destruction
161          due to double free of pScriptRefs).
162    
163      * src/Serialization.cpp, src/Serialization.h:
164        - Fixed broken Archive(RawData) constructor which always threw an
165          Exception.
166        - Added built-in support for C++ String objects (a.k.a. std::string
167          from the STL) and bumped Srx format version to 1.1 for that reason.
168        - Fixed assertion fault on some systems if a member variable defined was
169          serialized which was declared as size_t or ssize_t data type.
170        - Added new method Archive::operation() which allows applications to
171          distinguish between serialization vs. deserialization in their
172          serialize() method implementations.
173        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
174          the STL).
175        - Member offsets are now signed and for (newly added support of) member
176          variables on the heap -1 is always used as offset instead.
177        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
178          STL).
179        - DataType: Added optional 2nd custom type name.
180        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
181          STL).
182    
183      * src/helper.h:
184        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
185          function call.
186    
187      * src/tools/gigdump.cpp:
188        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
189          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
190          LFO2FlipPhase and LFO3FlipPhase.
191    
192    Version 4.2.0 (25 Jul 2019)
193    
194      * general changes:
195        - Added MSVC build support (anonymous patch from mailing list).
196        - Introduced CMake build support (yet constrained for building with MSVC)
197          (anonymous patch from mailing list).
198        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
199          destructors. Added new virtual method DeleteChunks() to those classes
200          for this which must be explicitly called instead to remove their RIFF
201          chunks.
202        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
203          of zero; which is unsafe per se.
204        - Added C++11 "override" keyword where appropriate.
205        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
206          of their actions when not passing a progress_t callback structure.
207    
208      * src/gig.cpp, src/gig.h:
209        - Fixed Doxygen API comments for enum types (currently latest Doxygen
210          [v1.8.13] only supports C comments in macro arguments expansion, but
211          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
212          the Doxygen source code, which currently also filter out new line
213          \n chars).
214        - Added new method File::CountSamples().
215        - Added new method File::CountInstruments().
216        - Fixed gig v4 files falsely being handled as v2 format
217          (patch by Ivan Maguidhir).
218        - Added gig v4 version identifier (File::VERSION_4).
219        - GIG FORMAT EXTENSION: Added attribute
220          DimensionRegion::SustainReleaseTrigger which allows to define whether
221          a sustain pedal up event shall cause a release trigger sample to be
222          played (default: don't play release trigger sample by sustain pedal).
223        - GIG FORMAT EXTENSION: Added attribute
224          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
225          regular behaviour of playing release trigger sample on MIDI note-off
226          events.
227        - Introduced support for writing extension files (.gx01, .gx02, ...)
228          (original patch by Ivan Maguidhir).
229        - Many gig classes derive now from DLS::Storage (see DLS changes below).
230        - Added File::GetRiffFile() method.
231    
232      * src/DLS.cpp, src/DLS.h:
233        - File: Fixed implicitly allocated RIFF::File object never been freed.
234        - Added new abstract interface base class DLS::Storage which is derived by
235          the respective classes for implementing (the old) UpdateChunks() and the
236          new DeleteChunks() method.
237        - Added File::GetRiffFile() method.
238    
239      * src/sf2.cpp, src/sf2.h:
240        - Added Sample::GetFile() method.
241        - Added File::GetRiffFile() method.
242    
243      * src/Serialization.cpp, src/Serialization.h:
244        - Hide pure internal declarations from header file to avoid numerous
245          compiler warnings when building and linking against the public API.
246        - Fixed comparision logic bug
247        - Fixed memory leak in DataType::customTypeName().
248    
249      * src/RIFF.cpp, src/RIFF.h:
250        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
251          caused a resource leak
252        - Avoid compiler warning when building for 32 bit windows.
253        - Added new method progress_t::subdivide().
254        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
255        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
256          allows a more fine graded control into which portions the subtasks are
257          divided to.
258    
259      * src/tools/gigdump.cpp:
260        - Added command line option --instrument-names which causes only
261          instrument names and their index numbers to be printed.
262    
263    Version 4.1.0 (25 Nov 2017)
264      * general changes:
265        - removed 2 GB limitation when loading a gig or DLS file
266        - using now native integer size where appropriate
267        - fixed minor issues with man pages (patch by Debian maintainer)
268        - fixed various spelling mistakes (patch by Debian maintainer)
269        - Added new "Serialization" framework (and equally named namespace)
270          which allows to serialize and deserialize native C++ objects
271          in a portable, easy and flexible way.
272        - print compiler warning if no RTTI available
273        - Fixed potential crash in command line tools gig2stereo, korg2gig,
274          korgdump and sf2extract.
275        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
276          (original patch by Paul Brossier, slightly modified).
277        - Debian: Fixed packaging error about invalid substitution variable
278          "Source-Version".
279        - Raised Debian compatibility level to Debian 9 "Stretch".
280    
281      * src/gig.cpp, src/gig.h:
282        - fixed bug in Script::SetGroup: the script chunk wasn't moved
283        - fixed compilation error with clang 3.4
284        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
285          as one single monolithic gig file. In case .gig file is >= 2GB expect a
286          large monolithic file, otherwise if .gig file is < 2 GB check for
287          "extension" files (.gx01, .gx02, ...) instead.
288        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
289          if there were dimensions after the velocity dimension: it only created
290          valid velocity tables for cases of dimensions lower than the velocity
291          dimension.
292        - added new method Sample::VerifyWaveData() which allows to check whether
293          a sample had been damaged for some reason
294        - Fix: samples' CRC checksums were damaged on file structure changes.
295        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
296        - Added new method Sample::GetWaveDataCRC32Checksum().
297        - Changed default value of EG2Release (filter release time) to 60s.
298        - Instruments' default pitch bend range is now +-2 semi tones.
299        - Fixed CRC checksums being wrong sometimes.
300        - Fix: method File::AddContentOf() did not clone script groups and scripts
301          of passed original file.
302        - Added support for serializing & deserializing DimensionRegion
303          objects (and crossfade_t and leverage_ctrl_t objects).
304        - Added enum reflection API functions for retrieving enum declaration type
305          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
306        - Exception class now has a variadic constructor which allows to add
307          textual format specifiers like with printf().
308        - On unknown leverage controller exception: show precise unknown leverage
309          controller number found.
310        - Ignore invalid leverage controller types and just show a warning on the
311          console instead of throwing an exception.
312        - Added new struct eg_opt_t and new class member variable
313          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
314          extension to the gig file format, which allows to override the default
315          behavior of the first two EGs' state machines.
316        - Fixed undefined behavior when loading a gig file with invalid
317          velocity curve parameters (fixes CVE-2017-12951).
318        - Fixed undefined behavior when loading a gig file with invalid wave
319          pool index number (fixes CVE-2017-12954).
320    
321      * src/DLS.cpp, src/DLS.h:
322        - Sample: wave pool offsets are now 64 bits (to allow support for files
323          larger than 4 GB).
324        - Exception class now has a variadic constructor which allows to add
325          textual format specifiers like with printf().
326    
327      * src/RIFF.cpp, src/RIFF.h:
328        - added support for RIFF files larger than 4 GB, by default the required
329          internal RIFF file offset size is automatically detected (that is RIFF
330          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
331          automatically use 64 bit offsets), a particular offset size can be forced
332          with a new option added to the RIFF File constructor though
333        - when saving a modified, grown RIFF file, the temporary file size during
334          Save() operation will no longer be larger than the final grown file size
335        - Exception class now has a variadic constructor which allows to add
336          textual format specifiers like with printf().
337    
338      * src/Serialization.cpp, src/Serialization.h:
339        - Archive: Added method isModified().
340        - Archive: Added method setAutoValue().
341        - Archive: Added method setIntValue().
342        - Archive: Added method setRealValue().
343        - Archive: Added method setBoolValue().
344        - Archive: Added method setEnumValue().
345        - Archive: Added method valueAsString().
346        - Archive::rawData(): Automatically re-encode new raw data stream if
347          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
348        - Object: Added method memberByUID().
349        - Object: remove() method is now protected.
350        - Archive: Added method removeMember().
351        - Archive: Added methods name() and setName().
352        - Archive: Added methods comment() and setComment().
353        - Archive: Added methods timeStampCreated(), timeStampModified(),
354          dateTimeCreated() and dateTimeModified().
355        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
356        - DataType: Implemented demangling C++ type names (for methods
357          asLongDescr() and customTypeName(bool demangle=false)).
358        - Archive::setAutoValue(): Handle human readable boolean text
359          representations like "yes", "no", "true", "false" as expected.
360        - Exception class now has a variadic constructor which allows to add
361          textual format specifiers like with printf().
362        - DataType fix: Retain backward compatibility to older versions of native
363          C++ classes/structs.
364    
365      * src/Akai.cpp:
366        - Fixed compilation error with recent, more strict compilers.
367    
368      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
369        - improved output of non-ascii characters in usage messages
370        - fixed printf format strings
371    
372      * src/tools/korg2gig.cpp:
373        - fixed c++11 narrowing warnings

478          (chunks at wrong location in the RIFF tree).
479        - Added new method Instrument::MoveTo() which allows to rearrange the order
480          of instruments within the same gig file.
481    
482      * src/DLS.cpp, src/DLS.h:

552          length files, now throws a RIFF::Exception instead (fixes bug #121)
553        - bugfix: destructor for base class RIFF::Chunk accessed members
554          of derived class RIFF::File, which is bad, and caused crashes
555          when using Visual C++

616          instruments
617        - write support: improved the default values for dimension region
618          parameters

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