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

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

661          group but moves all its members to another group, the other method,
662          that is File::DeleteGroup() now removes not just the group, but also
663          all the samples that belong to that group
