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