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

502          (chunks at wrong location in the RIFF tree).
503        - Added new method Instrument::MoveTo() which allows to rearrange the order
504          of instruments within the same gig file.
505    
506      * src/DLS.cpp, src/DLS.h:

532        - added new method Chunk::GetFile()
533        - added new method Chunk::GetLayout()
534        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

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

640          instruments
641        - write support: improved the default values for dimension region
642          parameters

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

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

759    
760      * src/gig.cpp, src/gig.h:

777          resize and write operations in one rush
778    
779      * src/gigdump.cpp:
780        - fixed to show the correct amount of dimension regions instead of 32
