89    Version 4.3.0 (9 May 2021)
90    
91      * general changes:
92        - Require at least a C++11 compliant compiler.
93        - Require some UUID generating function by underlying system.
94    
95      * src/gig.cpp, src/gig.h:
96        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
97          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
98          allow to define override LFOs' wave form (e.g. saw or square instead of
99          the default wave form which was always sine in the original
100          Gigasampler/GigaStudio software).
101        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
102          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
103          move the start point horizontally of the LFOs' waves (0° ... 360°).
104        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
105          (the original Gigasampler/GigaStudio software only had that flip phase
106          option for LFO1 and LFO2).
107        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
108          Region::UsesAnyGigFormatExtension(),
109          Instrument::UsesAnyGigFormatExtension() and
110          File::UsesAnyGigFormatExtension() (however only as private methods yet,
111          see comments on methods why).
112        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
113          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
114          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
115          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
116          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
117        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
118          (patch by Ivan Maguidhir).
119        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
120          (original patch by Ivan Maguidhir).
121        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
122          dimensions being in different order after deleting a dimension zone.
123        - Script: Generate a persistent UUID for each script.
124        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
125          accordingly added new methods to Instrument class:
126          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
127          GetScriptPatchVariable(), SetScriptPatchVariable(),
128          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
129          as child of our '3LS ' list chunk on Instrument level.
130        - Fixed undefined behaviour when modifying script slots on an instrument
131          that had been cloned and not been saved yet (e.g. unintended modification
132          of original instrument's script slots, and crash on Instrument destruction
133          due to double free of pScriptRefs).
134    
135      * src/Serialization.cpp, src/Serialization.h:
136        - Fixed broken Archive(RawData) constructor which always threw an
137          Exception.
138        - Added built-in support for C++ String objects (a.k.a. std::string
139          from the STL) and bumped Srx format version to 1.1 for that reason.
140        - Fixed assertion fault on some systems if a member variable defined was
141          serialized which was declared as size_t or ssize_t data type.
142        - Added new method Archive::operation() which allows applications to
143          distinguish between serialization vs. deserialization in their
144          serialize() method implementations.
145        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
146          the STL).
147        - Member offsets are now signed and for (newly added support of) member
148          variables on the heap -1 is always used as offset instead.
149        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
150          STL).
151        - DataType: Added optional 2nd custom type name.
152        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
153          STL).
154    
155      * src/helper.h:
156        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
157          function call.
158    
159      * src/tools/gigdump.cpp:
160        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
161          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
162          LFO2FlipPhase and LFO3FlipPhase.
163    
164    Version 4.2.0 (25 Jul 2019)
165    
166      * general changes:
167        - Added MSVC build support (anonymous patch from mailing list).
168        - Introduced CMake build support (yet constrained for building with MSVC)
169          (anonymous patch from mailing list).
170        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
171          destructors. Added new virtual method DeleteChunks() to those classes
172          for this which must be explicitly called instead to remove their RIFF
173          chunks.
174        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
175          of zero; which is unsafe per se.
176        - Added C++11 "override" keyword where appropriate.
177        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
178          of their actions when not passing a progress_t callback structure.
179    
180      * src/gig.cpp, src/gig.h:
181        - Fixed Doxygen API comments for enum types (currently latest Doxygen
182          [v1.8.13] only supports C comments in macro arguments expansion, but
183          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
184          the Doxygen source code, which currently also filter out new line
185          \n chars).
186        - Added new method File::CountSamples().
187        - Added new method File::CountInstruments().
188        - Fixed gig v4 files falsely being handled as v2 format
189          (patch by Ivan Maguidhir).
190        - Added gig v4 version identifier (File::VERSION_4).
191        - GIG FORMAT EXTENSION: Added attribute
192          DimensionRegion::SustainReleaseTrigger which allows to define whether
193          a sustain pedal up event shall cause a release trigger sample to be
194          played (default: don't play release trigger sample by sustain pedal).
195        - GIG FORMAT EXTENSION: Added attribute
196          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
197          regular behaviour of playing release trigger sample on MIDI note-off
198          events.
199        - Introduced support for writing extension files (.gx01, .gx02, ...)
200          (original patch by Ivan Maguidhir).
201        - Many gig classes derive now from DLS::Storage (see DLS changes below).
202        - Added File::GetRiffFile() method.
203    
204      * src/DLS.cpp, src/DLS.h:
205        - File: Fixed implicitly allocated RIFF::File object never been freed.
206        - Added new abstract interface base class DLS::Storage which is derived by
207          the respective classes for implementing (the old) UpdateChunks() and the
208          new DeleteChunks() method.
209        - Added File::GetRiffFile() method.
210    
211      * src/sf2.cpp, src/sf2.h:
212        - Added Sample::GetFile() method.
213        - Added File::GetRiffFile() method.
214    
215      * src/Serialization.cpp, src/Serialization.h:
216        - Hide pure internal declarations from header file to avoid numerous
217          compiler warnings when building and linking against the public API.
218        - Fixed comparision logic bug
219        - Fixed memory leak in DataType::customTypeName().
220    
221      * src/RIFF.cpp, src/RIFF.h:
222        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
223          caused a resource leak
224        - Avoid compiler warning when building for 32 bit windows.
225        - Added new method progress_t::subdivide().
226        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
227        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
228          allows a more fine graded control into which portions the subtasks are
229          divided to.
230    
231      * src/tools/gigdump.cpp:
232        - Added command line option --instrument-names which causes only
233          instrument names and their index numbers to be printed.
234    
235    Version 4.1.0 (25 Nov 2017)
236      * general changes:
237        - removed 2 GB limitation when loading a gig or DLS file
238        - using now native integer size where appropriate
239        - fixed minor issues with man pages (patch by Debian maintainer)
240        - fixed various spelling mistakes (patch by Debian maintainer)
241        - Added new "Serialization" framework (and equally named namespace)
242          which allows to serialize and deserialize native C++ objects
243          in a portable, easy and flexible way.
244        - print compiler warning if no RTTI available
245        - Fixed potential crash in command line tools gig2stereo, korg2gig,
246          korgdump and sf2extract.
247        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
248          (original patch by Paul Brossier, slightly modified).
249        - Debian: Fixed packaging error about invalid substitution variable
250          "Source-Version".
251        - Raised Debian compatibility level to Debian 9 "Stretch".
252    
253      * src/gig.cpp, src/gig.h:
254        - fixed bug in Script::SetGroup: the script chunk wasn't moved
255        - fixed compilation error with clang 3.4
256        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
257          as one single monolithic gig file. In case .gig file is >= 2GB expect a
258          large monolithic file, otherwise if .gig file is < 2 GB check for
259          "extension" files (.gx01, .gx02, ...) instead.
260        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
261          if there were dimensions after the velocity dimension: it only created
262          valid velocity tables for cases of dimensions lower than the velocity
263          dimension.
264        - added new method Sample::VerifyWaveData() which allows to check whether
265          a sample had been damaged for some reason
266        - Fix: samples' CRC checksums were damaged on file structure changes.
267        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
268        - Added new method Sample::GetWaveDataCRC32Checksum().
269        - Changed default value of EG2Release (filter release time) to 60s.
270        - Instruments' default pitch bend range is now +-2 semi tones.
271        - Fixed CRC checksums being wrong sometimes.
272        - Fix: method File::AddContentOf() did not clone script groups and scripts
273          of passed original file.
274        - Added support for serializing & deserializing DimensionRegion
275          objects (and crossfade_t and leverage_ctrl_t objects).
276        - Added enum reflection API functions for retrieving enum declaration type
277          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
278        - Exception class now has a variadic constructor which allows to add
279          textual format specifiers like with printf().
280        - On unknown leverage controller exception: show precise unknown leverage
281          controller number found.
282        - Ignore invalid leverage controller types and just show a warning on the
283          console instead of throwing an exception.
284        - Added new struct eg_opt_t and new class member variable
285          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
286          extension to the gig file format, which allows to override the default
287          behavior of the first two EGs' state machines.
288        - Fixed undefined behavior when loading a gig file with invalid
289          velocity curve parameters (fixes CVE-2017-12951).
290        - Fixed undefined behavior when loading a gig file with invalid wave
291          pool index number (fixes CVE-2017-12954).
292    
293      * src/DLS.cpp, src/DLS.h:
294        - Sample: wave pool offsets are now 64 bits (to allow support for files
295          larger than 4 GB).
296        - Exception class now has a variadic constructor which allows to add
297          textual format specifiers like with printf().
298    
299      * src/RIFF.cpp, src/RIFF.h:
300        - added support for RIFF files larger than 4 GB, by default the required
301          internal RIFF file offset size is automatically detected (that is RIFF
302          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
303          automatically use 64 bit offsets), a particular offset size can be forced
304          with a new option added to the RIFF File constructor though
305        - when saving a modified, grown RIFF file, the temporary file size during
306          Save() operation will no longer be larger than the final grown file size
307        - Exception class now has a variadic constructor which allows to add
308          textual format specifiers like with printf().
309    
310      * src/Serialization.cpp, src/Serialization.h:
311        - Archive: Added method isModified().
312        - Archive: Added method setAutoValue().
313        - Archive: Added method setIntValue().
314        - Archive: Added method setRealValue().
315        - Archive: Added method setBoolValue().
316        - Archive: Added method setEnumValue().
317        - Archive: Added method valueAsString().
318        - Archive::rawData(): Automatically re-encode new raw data stream if
319          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
320        - Object: Added method memberByUID().
321        - Object: remove() method is now protected.
322        - Archive: Added method removeMember().
323        - Archive: Added methods name() and setName().
324        - Archive: Added methods comment() and setComment().
325        - Archive: Added methods timeStampCreated(), timeStampModified(),
326          dateTimeCreated() and dateTimeModified().
327        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
328        - DataType: Implemented demangling C++ type names (for methods
329          asLongDescr() and customTypeName(bool demangle=false)).
330        - Archive::setAutoValue(): Handle human readable boolean text
331          representations like "yes", "no", "true", "false" as expected.
332        - Exception class now has a variadic constructor which allows to add
333          textual format specifiers like with printf().
334        - DataType fix: Retain backward compatibility to older versions of native
335          C++ classes/structs.
336    
337      * src/Akai.cpp:
338        - Fixed compilation error with recent, more strict compilers.
339    
340      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
341        - improved output of non-ascii characters in usage messages
342        - fixed printf format strings
343    
344      * src/tools/korg2gig.cpp:
345        - fixed c++11 narrowing warnings
346        - fixed fine tuning which was not translated at all
347    
348      * src/tools/gigdump.cpp:
349        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
350          dimension regions
351        - additionally print RIFF chunk file offset and RIFF chunk size of sample
352          data
353        - added and implemented new parameter "--verify" which allows to check
354          the raw wave form data integrity of all samples
355        - added and implemented new parameter "--rebuild-checksums" which allows
356          to recalculate the CRC32 checksum of all samples' raw wave data and
357          rebuilding the gig file's global checksum table (i.e. in case the
358          file's checksum table was damaged)
359        - print samples' CRC32 checksums
360        - Print the new EG behavior options (eg_opt_t).
361    
362      * src/tools/gigextract.cpp:
363        - Fix: if sample name contains a path separator (slash or backslash) then
364          replace them by a minus sign to avoid file system issues.
365    
366      * src/tools/gig2stereo.cpp:
367        - Also merge mono sample pairs with non matching loop information if
368          argument --incompatible was given.
369    
370      * packaging changes:
371        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
372          auto detect whether it (sh/c)ould output its messages in color.
373    
374    Version 4.0.0 (14 Jul 2015)
375      * general changes:
376        - minor Makefile fix for parallel make
377        - Mac OS X: link with CoreFoundation (for the UUID function)
378        - removed gcc 4.7 warnings

450          (chunks at wrong location in the RIFF tree).
451        - Added new method Instrument::MoveTo() which allows to rearrange the order
452          of instruments within the same gig file.
453    
454      * src/DLS.cpp, src/DLS.h:

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

588          instruments
589        - write support: improved the default values for dimension region

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