53    
54    Version 4.3.0 (9 May 2021)
55    
56      * general changes:
57        - Require at least a C++11 compliant compiler.
58        - Require some UUID generating function by underlying system.
59    
60      * src/gig.cpp, src/gig.h:
61        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
62          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
63          allow to define override LFOs' wave form (e.g. saw or square instead of
64          the default wave form which was always sine in the original
65          Gigasampler/GigaStudio software).
66        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
67          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
68          move the start point horizontally of the LFOs' waves (0° ... 360°).
69        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
70          (the original Gigasampler/GigaStudio software only had that flip phase
71          option for LFO1 and LFO2).
72        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
73          Region::UsesAnyGigFormatExtension(),
74          Instrument::UsesAnyGigFormatExtension() and
75          File::UsesAnyGigFormatExtension() (however only as private methods yet,
76          see comments on methods why).
77        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
78          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
79          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
80          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
81          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
82        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
83          (patch by Ivan Maguidhir).
84        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
85          (original patch by Ivan Maguidhir).
86        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
87          dimensions being in different order after deleting a dimension zone.
88        - Script: Generate a persistent UUID for each script.
89        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
90          accordingly added new methods to Instrument class:
91          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
92          GetScriptPatchVariable(), SetScriptPatchVariable(),
93          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
94          as child of our '3LS ' list chunk on Instrument level.
95        - Fixed undefined behaviour when modifying script slots on an instrument
96          that had been cloned and not been saved yet (e.g. unintended modification
97          of original instrument's script slots, and crash on Instrument destruction
98          due to double free of pScriptRefs).
99    
100      * src/Serialization.cpp, src/Serialization.h:
101        - Fixed broken Archive(RawData) constructor which always threw an
102          Exception.
103        - Added built-in support for C++ String objects (a.k.a. std::string
104          from the STL) and bumped Srx format version to 1.1 for that reason.
105        - Fixed assertion fault on some systems if a member variable defined was
106          serialized which was declared as size_t or ssize_t data type.
107        - Added new method Archive::operation() which allows applications to
108          distinguish between serialization vs. deserialization in their
109          serialize() method implementations.
110        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
111          the STL).
112        - Member offsets are now signed and for (newly added support of) member
113          variables on the heap -1 is always used as offset instead.
114        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
115          STL).
116        - DataType: Added optional 2nd custom type name.
117        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
118          STL).
119    
120      * src/helper.h:
121        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
122          function call.
123    
124      * src/tools/gigdump.cpp:
125        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
126          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
127          LFO2FlipPhase and LFO3FlipPhase.
128    
129    Version 4.2.0 (25 Jul 2019)
130    
131      * general changes:
132        - Added MSVC build support (anonymous patch from mailing list).
133        - Introduced CMake build support (yet constrained for building with MSVC)
134          (anonymous patch from mailing list).
135        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
136          destructors. Added new virtual method DeleteChunks() to those classes
137          for this which must be explicitly called instead to remove their RIFF
138          chunks.
139        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
140          of zero; which is unsafe per se.
141        - Added C++11 "override" keyword where appropriate.
142        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
143          of their actions when not passing a progress_t callback structure.
144    
145      * src/gig.cpp, src/gig.h:
146        - Fixed Doxygen API comments for enum types (currently latest Doxygen
147          [v1.8.13] only supports C comments in macro arguments expansion, but
148          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
149          the Doxygen source code, which currently also filter out new line
150          \n chars).
151        - Added new method File::CountSamples().
152        - Added new method File::CountInstruments().
153        - Fixed gig v4 files falsely being handled as v2 format
154          (patch by Ivan Maguidhir).
155        - Added gig v4 version identifier (File::VERSION_4).
156        - GIG FORMAT EXTENSION: Added attribute
157          DimensionRegion::SustainReleaseTrigger which allows to define whether
158          a sustain pedal up event shall cause a release trigger sample to be
159          played (default: don't play release trigger sample by sustain pedal).
160        - GIG FORMAT EXTENSION: Added attribute
161          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
162          regular behaviour of playing release trigger sample on MIDI note-off
163          events.
164        - Introduced support for writing extension files (.gx01, .gx02, ...)
165          (original patch by Ivan Maguidhir).
166        - Many gig classes derive now from DLS::Storage (see DLS changes below).
167        - Added File::GetRiffFile() method.
168    
169      * src/DLS.cpp, src/DLS.h:
170        - File: Fixed implicitly allocated RIFF::File object never been freed.
171        - Added new abstract interface base class DLS::Storage which is derived by
172          the respective classes for implementing (the old) UpdateChunks() and the
173          new DeleteChunks() method.
174        - Added File::GetRiffFile() method.
175    
176      * src/sf2.cpp, src/sf2.h:
177        - Added Sample::GetFile() method.
178        - Added File::GetRiffFile() method.
179    
180      * src/Serialization.cpp, src/Serialization.h:
181        - Hide pure internal declarations from header file to avoid numerous
182          compiler warnings when building and linking against the public API.
183        - Fixed comparision logic bug
184        - Fixed memory leak in DataType::customTypeName().
185    
186      * src/RIFF.cpp, src/RIFF.h:
187        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
188          caused a resource leak
189        - Avoid compiler warning when building for 32 bit windows.
190        - Added new method progress_t::subdivide().
191        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
192        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
193          allows a more fine graded control into which portions the subtasks are
194          divided to.
195    
196      * src/tools/gigdump.cpp:
197        - Added command line option --instrument-names which causes only
198          instrument names and their index numbers to be printed.
199    
200    Version 4.1.0 (25 Nov 2017)
201      * general changes:
202        - removed 2 GB limitation when loading a gig or DLS file
203        - using now native integer size where appropriate
204        - fixed minor issues with man pages (patch by Debian maintainer)
205        - fixed various spelling mistakes (patch by Debian maintainer)
206        - Added new "Serialization" framework (and equally named namespace)
207          which allows to serialize and deserialize native C++ objects
208          in a portable, easy and flexible way.
209        - print compiler warning if no RTTI available
210        - Fixed potential crash in command line tools gig2stereo, korg2gig,
211          korgdump and sf2extract.
212        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
213          (original patch by Paul Brossier, slightly modified).
214        - Debian: Fixed packaging error about invalid substitution variable
215          "Source-Version".
216        - Raised Debian compatibility level to Debian 9 "Stretch".
217    
218      * src/gig.cpp, src/gig.h:
219        - fixed bug in Script::SetGroup: the script chunk wasn't moved
220        - fixed compilation error with clang 3.4
221        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
222          as one single monolithic gig file. In case .gig file is >= 2GB expect a
223          large monolithic file, otherwise if .gig file is < 2 GB check for
224          "extension" files (.gx01, .gx02, ...) instead.
225        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
226          if there were dimensions after the velocity dimension: it only created
227          valid velocity tables for cases of dimensions lower than the velocity
228          dimension.
229        - added new method Sample::VerifyWaveData() which allows to check whether
230          a sample had been damaged for some reason
231        - Fix: samples' CRC checksums were damaged on file structure changes.
232        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
233        - Added new method Sample::GetWaveDataCRC32Checksum().
234        - Changed default value of EG2Release (filter release time) to 60s.
235        - Instruments' default pitch bend range is now +-2 semi tones.
236        - Fixed CRC checksums being wrong sometimes.
237        - Fix: method File::AddContentOf() did not clone script groups and scripts
238          of passed original file.
239        - Added support for serializing & deserializing DimensionRegion
240          objects (and crossfade_t and leverage_ctrl_t objects).
241        - Added enum reflection API functions for retrieving enum declaration type
242          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
243        - Exception class now has a variadic constructor which allows to add
244          textual format specifiers like with printf().
245        - On unknown leverage controller exception: show precise unknown leverage
246          controller number found.
247        - Ignore invalid leverage controller types and just show a warning on the
248          console instead of throwing an exception.
249        - Added new struct eg_opt_t and new class member variable
250          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
251          extension to the gig file format, which allows to override the default
252          behavior of the first two EGs' state machines.
253        - Fixed undefined behavior when loading a gig file with invalid
254          velocity curve parameters (fixes CVE-2017-12951).
255        - Fixed undefined behavior when loading a gig file with invalid wave
256          pool index number (fixes CVE-2017-12954).
257    
258      * src/DLS.cpp, src/DLS.h:
259        - Sample: wave pool offsets are now 64 bits (to allow support for files
260          larger than 4 GB).
261        - Exception class now has a variadic constructor which allows to add
262          textual format specifiers like with printf().
263    
264      * src/RIFF.cpp, src/RIFF.h:
265        - added support for RIFF files larger than 4 GB, by default the required
266          internal RIFF file offset size is automatically detected (that is RIFF
267          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
268          automatically use 64 bit offsets), a particular offset size can be forced
269          with a new option added to the RIFF File constructor though
270        - when saving a modified, grown RIFF file, the temporary file size during
271          Save() operation will no longer be larger than the final grown file size
272        - Exception class now has a variadic constructor which allows to add
273          textual format specifiers like with printf().
274    
275      * src/Serialization.cpp, src/Serialization.h:
276        - Archive: Added method isModified().
277        - Archive: Added method setAutoValue().

280        - Archive: Added method setBoolValue().
281        - Archive: Added method setEnumValue().
282        - Archive: Added method valueAsString().
283        - Archive::rawData(): Automatically re-encode new raw data stream if
284          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
285        - Object: Added method memberByUID().
286        - Object: remove() method is now protected.
287        - Archive: Added method removeMember().
288        - Archive: Added methods name() and setName().
289        - Archive: Added methods comment() and setComment().
290        - Archive: Added methods timeStampCreated(), timeStampModified(),
291          dateTimeCreated() and dateTimeModified().
292        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
293        - DataType: Implemented demangling C++ type names (for methods
294          asLongDescr() and customTypeName(bool demangle=false)).
295        - Archive::setAutoValue(): Handle human readable boolean text
296          representations like "yes", "no", "true", "false" as expected.
297        - Exception class now has a variadic constructor which allows to add
298          textual format specifiers like with printf().
299        - DataType fix: Retain backward compatibility to older versions of native
300          C++ classes/structs.
301    
302      * src/Akai.cpp:
303        - Fixed compilation error with recent, more strict compilers.
304    
305      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:

308    
309      * src/tools/korg2gig.cpp:
310        - fixed c++11 narrowing warnings
311        - fixed fine tuning which was not translated at all
312    
313      * src/tools/gigdump.cpp:
314        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
315          dimension regions
316        - additionally print RIFF chunk file offset and RIFF chunk size of sample
317          data
318        - added and implemented new parameter "--verify" which allows to check
319          the raw wave form data integrity of all samples
320        - added and implemented new parameter "--rebuild-checksums" which allows
321          to recalculate the CRC32 checksum of all samples' raw wave data and
322          rebuilding the gig file's global checksum table (i.e. in case the
323          file's checksum table was damaged)
324        - print samples' CRC32 checksums
325        - Print the new EG behavior options (eg_opt_t).
326    
327      * src/tools/gigextract.cpp:
328        - Fix: if sample name contains a path separator (slash or backslash) then
329          replace them by a minus sign to avoid file system issues.
330    
331      * src/tools/gig2stereo.cpp:
332        - Also merge mono sample pairs with non matching loop information if
333          argument --incompatible was given.
334    
335      * packaging changes:
336        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
337          auto detect whether it (sh/c)ould output its messages in color.
338
