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

499          (chunks at wrong location in the RIFF tree).
500        - Added new method Instrument::MoveTo() which allows to rearrange the order
501          of instruments within the same gig file.
502    
503      * src/DLS.cpp, src/DLS.h:

529        - added new method Chunk::GetFile()
530        - added new method Chunk::GetLayout()
531        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

573          length files, now throws a RIFF::Exception instead (fixes bug #121)
574        - bugfix: destructor for base class RIFF::Chunk accessed members
575          of derived class RIFF::File, which is bad, and caused crashes
576          when using Visual C++
577        - bugfix: files that contain zero length RIFF lists were not read
578          correctly (fixes #127) (bug was introduced 2009-03-13)
579

637          instruments
638        - write support: improved the default values for dimension region
639          parameters

680        - added new method File::DeleteGroupOnly() which only deletes the given
681          group but moves all its members to another group, the other method,
682          that is File::DeleteGroup() now removes not just the group, but also
683          all the samples that belong to that group
684        - fixed crash which occured on interfering File::DeleteSample() and
685          File::GetNextSample() calls (due to iterator invalidation)

720          instead of the wave chunk
721        - keyswitching dimension is changed from split type "normal" to
722          "bit"
723        - real support for 24 bit samples - samples are not truncated to

756    
757      * src/gig.cpp, src/gig.h:

774          resize and write operations in one rush
775    
776      * src/gigdump.cpp:
777        - fixed to show the correct amount of dimension regions instead of 32
