79    Version 4.3.0 (9 May 2021)
80    
81      * general changes:
82        - Require at least a C++11 compliant compiler.
83        - Require some UUID generating function by underlying system.
84    
85      * src/gig.cpp, src/gig.h:
86        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
87          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
88          allow to define override LFOs' wave form (e.g. saw or square instead of
89          the default wave form which was always sine in the original
90          Gigasampler/GigaStudio software).
91        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
92          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
93          move the start point horizontally of the LFOs' waves (0° ... 360°).
94        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
95          (the original Gigasampler/GigaStudio software only had that flip phase
96          option for LFO1 and LFO2).
97        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
98          Region::UsesAnyGigFormatExtension(),
99          Instrument::UsesAnyGigFormatExtension() and
100          File::UsesAnyGigFormatExtension() (however only as private methods yet,
101          see comments on methods why).
102        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
103          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
104          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
105          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
106          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
107        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
108          (patch by Ivan Maguidhir).
109        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
110          (original patch by Ivan Maguidhir).
111        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
112          dimensions being in different order after deleting a dimension zone.
113        - Script: Generate a persistent UUID for each script.
114        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
115          accordingly added new methods to Instrument class:
116          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
117          GetScriptPatchVariable(), SetScriptPatchVariable(),
118          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
119          as child of our '3LS ' list chunk on Instrument level.
120        - Fixed undefined behaviour when modifying script slots on an instrument
121          that had been cloned and not been saved yet (e.g. unintended modification
122          of original instrument's script slots, and crash on Instrument destruction
123          due to double free of pScriptRefs).
124    
125      * src/Serialization.cpp, src/Serialization.h:
126        - Fixed broken Archive(RawData) constructor which always threw an
127          Exception.
128        - Added built-in support for C++ String objects (a.k.a. std::string
129          from the STL) and bumped Srx format version to 1.1 for that reason.
130        - Fixed assertion fault on some systems if a member variable defined was
131          serialized which was declared as size_t or ssize_t data type.
132        - Added new method Archive::operation() which allows applications to
133          distinguish between serialization vs. deserialization in their
134          serialize() method implementations.
135        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
136          the STL).
137        - Member offsets are now signed and for (newly added support of) member
138          variables on the heap -1 is always used as offset instead.
139        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
140          STL).
141        - DataType: Added optional 2nd custom type name.
142        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
143          STL).
144    
145      * src/helper.h:
146        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
147          function call.
148    
149      * src/tools/gigdump.cpp:
150        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
151          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
152          LFO2FlipPhase and LFO3FlipPhase.
153    
154    Version 4.2.0 (25 Jul 2019)
155    
156      * general changes:
157        - Added MSVC build support (anonymous patch from mailing list).
158        - Introduced CMake build support (yet constrained for building with MSVC)
159          (anonymous patch from mailing list).
160        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
161          destructors. Added new virtual method DeleteChunks() to those classes
162          for this which must be explicitly called instead to remove their RIFF
163          chunks.
164        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
165          of zero; which is unsafe per se.
166        - Added C++11 "override" keyword where appropriate.
167        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
168          of their actions when not passing a progress_t callback structure.
169    
170      * src/gig.cpp, src/gig.h:
171        - Fixed Doxygen API comments for enum types (currently latest Doxygen
172          [v1.8.13] only supports C comments in macro arguments expansion, but
173          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
174          the Doxygen source code, which currently also filter out new line
175          \n chars).
176        - Added new method File::CountSamples().
177        - Added new method File::CountInstruments().
178        - Fixed gig v4 files falsely being handled as v2 format
179          (patch by Ivan Maguidhir).
180        - Added gig v4 version identifier (File::VERSION_4).
181        - GIG FORMAT EXTENSION: Added attribute
182          DimensionRegion::SustainReleaseTrigger which allows to define whether
183          a sustain pedal up event shall cause a release trigger sample to be
184          played (default: don't play release trigger sample by sustain pedal).
185        - GIG FORMAT EXTENSION: Added attribute
186          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
187          regular behaviour of playing release trigger sample on MIDI note-off
188          events.
189        - Introduced support for writing extension files (.gx01, .gx02, ...)
190          (original patch by Ivan Maguidhir).
191        - Many gig classes derive now from DLS::Storage (see DLS changes below).
192        - Added File::GetRiffFile() method.
193    
194      * src/DLS.cpp, src/DLS.h:
195        - File: Fixed implicitly allocated RIFF::File object never been freed.
196        - Added new abstract interface base class DLS::Storage which is derived by
197          the respective classes for implementing (the old) UpdateChunks() and the
198          new DeleteChunks() method.
199        - Added File::GetRiffFile() method.
200    
201      * src/sf2.cpp, src/sf2.h:
202        - Added Sample::GetFile() method.
203        - Added File::GetRiffFile() method.
204    
205      * src/Serialization.cpp, src/Serialization.h:
206        - Hide pure internal declarations from header file to avoid numerous
207          compiler warnings when building and linking against the public API.
208        - Fixed comparision logic bug
209        - Fixed memory leak in DataType::customTypeName().
210    
211      * src/RIFF.cpp, src/RIFF.h:
212        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
213          caused a resource leak
214        - Avoid compiler warning when building for 32 bit windows.
215        - Added new method progress_t::subdivide().
216        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
217        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
218          allows a more fine graded control into which portions the subtasks are
219          divided to.
220    
221      * src/tools/gigdump.cpp:
222        - Added command line option --instrument-names which causes only
223          instrument names and their index numbers to be printed.
224    
225    Version 4.1.0 (25 Nov 2017)
226      * general changes:
227        - removed 2 GB limitation when loading a gig or DLS file
228        - using now native integer size where appropriate
229        - fixed minor issues with man pages (patch by Debian maintainer)
230        - fixed various spelling mistakes (patch by Debian maintainer)
231        - Added new "Serialization" framework (and equally named namespace)
232          which allows to serialize and deserialize native C++ objects
233          in a portable, easy and flexible way.
234        - print compiler warning if no RTTI available
235        - Fixed potential crash in command line tools gig2stereo, korg2gig,
236          korgdump and sf2extract.
237        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
238          (original patch by Paul Brossier, slightly modified).
239        - Debian: Fixed packaging error about invalid substitution variable
240          "Source-Version".
241        - Raised Debian compatibility level to Debian 9 "Stretch".
242    
243      * src/gig.cpp, src/gig.h:
244        - fixed bug in Script::SetGroup: the script chunk wasn't moved
245        - fixed compilation error with clang 3.4
246        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
247          as one single monolithic gig file. In case .gig file is >= 2GB expect a
248          large monolithic file, otherwise if .gig file is < 2 GB check for
249          "extension" files (.gx01, .gx02, ...) instead.
250        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
251          if there were dimensions after the velocity dimension: it only created
252          valid velocity tables for cases of dimensions lower than the velocity
253          dimension.
254        - added new method Sample::VerifyWaveData() which allows to check whether
255          a sample had been damaged for some reason
256        - Fix: samples' CRC checksums were damaged on file structure changes.
257        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
258        - Added new method Sample::GetWaveDataCRC32Checksum().
259        - Changed default value of EG2Release (filter release time) to 60s.
260        - Instruments' default pitch bend range is now +-2 semi tones.
261        - Fixed CRC checksums being wrong sometimes.
262        - Fix: method File::AddContentOf() did not clone script groups and scripts
263          of passed original file.
264        - Added support for serializing & deserializing DimensionRegion
265          objects (and crossfade_t and leverage_ctrl_t objects).
266        - Added enum reflection API functions for retrieving enum declaration type
267          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
268        - Exception class now has a variadic constructor which allows to add
269          textual format specifiers like with printf().
270        - On unknown leverage controller exception: show precise unknown leverage
271          controller number found.
272        - Ignore invalid leverage controller types and just show a warning on the
273          console instead of throwing an exception.
274        - Added new struct eg_opt_t and new class member variable
275          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
276          extension to the gig file format, which allows to override the default
277          behavior of the first two EGs' state machines.
278        - Fixed undefined behavior when loading a gig file with invalid
279          velocity curve parameters (fixes CVE-2017-12951).
280        - Fixed undefined behavior when loading a gig file with invalid wave
281          pool index number (fixes CVE-2017-12954).
282    
283      * src/DLS.cpp, src/DLS.h:
284        - Sample: wave pool offsets are now 64 bits (to allow support for files
285          larger than 4 GB).
286        - Exception class now has a variadic constructor which allows to add
287          textual format specifiers like with printf().
288    
289      * src/RIFF.cpp, src/RIFF.h:
290        - added support for RIFF files larger than 4 GB, by default the required
291          internal RIFF file offset size is automatically detected (that is RIFF
292          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
293          automatically use 64 bit offsets), a particular offset size can be forced
294          with a new option added to the RIFF File constructor though
295        - when saving a modified, grown RIFF file, the temporary file size during
296          Save() operation will no longer be larger than the final grown file size
297        - Exception class now has a variadic constructor which allows to add
298          textual format specifiers like with printf().
299    
300      * src/Serialization.cpp, src/Serialization.h:
301        - Archive: Added method isModified().
302        - Archive: Added method setAutoValue().
303        - Archive: Added method setIntValue().
304        - Archive: Added method setRealValue().
305        - Archive: Added method setBoolValue().
306        - Archive: Added method setEnumValue().
307        - Archive: Added method valueAsString().
308        - Archive::rawData(): Automatically re-encode new raw data stream if
309          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
310        - Object: Added method memberByUID().
311        - Object: remove() method is now protected.
312        - Archive: Added method removeMember().
313        - Archive: Added methods name() and setName().
314        - Archive: Added methods comment() and setComment().
315        - Archive: Added methods timeStampCreated(), timeStampModified(),
316          dateTimeCreated() and dateTimeModified().
317        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
318        - DataType: Implemented demangling C++ type names (for methods
319          asLongDescr() and customTypeName(bool demangle=false)).
320        - Archive::setAutoValue(): Handle human readable boolean text
321          representations like "yes", "no", "true", "false" as expected.
322        - Exception class now has a variadic constructor which allows to add
323          textual format specifiers like with printf().
324        - DataType fix: Retain backward compatibility to older versions of native
325          C++ classes/structs.
326    
327      * src/Akai.cpp:
328        - Fixed compilation error with recent, more strict compilers.
329    
330      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
331        - improved output of non-ascii characters in usage messages
332        - fixed printf format strings
333    
334      * src/tools/korg2gig.cpp:
335        - fixed c++11 narrowing warnings
336        - fixed fine tuning which was not translated at all
337    
338      * src/tools/gigdump.cpp:
339        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
340          dimension regions
341        - additionally print RIFF chunk file offset and RIFF chunk size of sample
342          data
343        - added and implemented new parameter "--verify" which allows to check
344          the raw wave form data integrity of all samples
345        - added and implemented new parameter "--rebuild-checksums" which allows
346          to recalculate the CRC32 checksum of all samples' raw wave data and
347          rebuilding the gig file's global checksum table (i.e. in case the
348          file's checksum table was damaged)
349        - print samples' CRC32 checksums
350        - Print the new EG behavior options (eg_opt_t).
351    
352      * src/tools/gigextract.cpp:
353        - Fix: if sample name contains a path separator (slash or backslash) then
354          replace them by a minus sign to avoid file system issues.
355    
356      * src/tools/gig2stereo.cpp:
357        - Also merge mono sample pairs with non matching loop information if
358          argument --incompatible was given.
359    
360      * packaging changes:
361        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
362          auto detect whether it (sh/c)ould output its messages in color.
363    
364    Version 4.0.0 (14 Jul 2015)

440          (chunks at wrong location in the RIFF tree).
441        - Added new method Instrument::MoveTo() which allows to rearrange the order
442          of instruments within the same gig file.
443    
444      * src/DLS.cpp, src/DLS.h:

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

519          correctly (fixes #127) (bug was introduced 2009-03-13)
520    
521    Version 3.2.1 (5 Dec 2007)
522

578          instruments
579        - write support: improved the default values for dimension region

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