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

490          (chunks at wrong location in the RIFF tree).
491        - Added new method Instrument::MoveTo() which allows to rearrange the order
492          of instruments within the same gig file.
493    
494      * src/DLS.cpp, src/DLS.h:

520        - added new method Chunk::GetFile()
521        - added new method Chunk::GetLayout()
522        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

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

627        - write support: DLSID is now generated on the file and the
628          instruments
629        - write support: improved the default values for dimension region
630          parameters

671        - added new method File::DeleteGroupOnly() which only deletes the given
672          group but moves all its members to another group, the other method,
673          that is File::DeleteGroup() now removes not just the group, but also
674          all the samples that belong to that group
675        - fixed crash which occured on interfering File::DeleteSample() and
676          File::GetNextSample() calls (due to iterator invalidation)

711          instead of the wave chunk
712        - keyswitching dimension is changed from split type "normal" to
713          "bit"
714        - real support for 24 bit samples - samples are not truncated to

765          resize and write operations in one rush
766    
767      * src/gigdump.cpp:
