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

336        - fixed printf format strings
337    
338      * src/tools/korg2gig.cpp:
339        - fixed c++11 narrowing warnings
340        - fixed fine tuning which was not translated at all
341    
342      * src/tools/gigdump.cpp:
343        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
344          dimension regions
345        - additionally print RIFF chunk file offset and RIFF chunk size of sample
346          data
347        - added and implemented new parameter "--verify" which allows to check
348          the raw wave form data integrity of all samples
349        - added and implemented new parameter "--rebuild-checksums" which allows
350          to recalculate the CRC32 checksum of all samples' raw wave data and
351          rebuilding the gig file's global checksum table (i.e. in case the
352          file's checksum table was damaged)
353        - print samples' CRC32 checksums
354        - Print the new EG behavior options (eg_opt_t).
355    
356      * src/tools/gigextract.cpp:
357        - Fix: if sample name contains a path separator (slash or backslash) then
358          replace them by a minus sign to avoid file system issues.
359    
360      * src/tools/gig2stereo.cpp:
361        - Also merge mono sample pairs with non matching loop information if
362          argument --incompatible was given.
363    
364      * packaging changes:
365        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
366          auto detect whether it (sh/c)ould output its messages in color.
