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

307        - Archive: Added method setBoolValue().
308        - Archive: Added method setEnumValue().
309        - Archive: Added method valueAsString().
310        - Archive::rawData(): Automatically re-encode new raw data stream if
311          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
312        - Object: Added method memberByUID().
313        - Object: remove() method is now protected.
314        - Archive: Added method removeMember().
315        - Archive: Added methods name() and setName().
316        - Archive: Added methods comment() and setComment().
317        - Archive: Added methods timeStampCreated(), timeStampModified(),
318          dateTimeCreated() and dateTimeModified().
319        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
320        - DataType: Implemented demangling C++ type names (for methods
321          asLongDescr() and customTypeName(bool demangle=false)).
322        - Archive::setAutoValue(): Handle human readable boolean text
323          representations like "yes", "no", "true", "false" as expected.
324        - Exception class now has a variadic constructor which allows to add
325          textual format specifiers like with printf().
326        - DataType fix: Retain backward compatibility to older versions of native
327          C++ classes/structs.
328    
329      * src/Akai.cpp:
330        - Fixed compilation error with recent, more strict compilers.
331    
332      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:

335    
336      * src/tools/korg2gig.cpp:
337        - fixed c++11 narrowing warnings
338        - fixed fine tuning which was not translated at all
339    
340      * src/tools/gigdump.cpp:
341        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
342          dimension regions
343        - additionally print RIFF chunk file offset and RIFF chunk size of sample
344          data
345        - added and implemented new parameter "--verify" which allows to check
346          the raw wave form data integrity of all samples
347        - added and implemented new parameter "--rebuild-checksums" which allows
348          to recalculate the CRC32 checksum of all samples' raw wave data and
349          rebuilding the gig file's global checksum table (i.e. in case the
350          file's checksum table was damaged)
351        - print samples' CRC32 checksums
352        - Print the new EG behavior options (eg_opt_t).
353    
354      * src/tools/gigextract.cpp:
355        - Fix: if sample name contains a path separator (slash or backslash) then
