1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * src/gig.cpp, src/gig.h:
4        - Region::DeleteDimensionZone(): Fix clang sanatizer warning.
5        - Region::SplitDimensionZone(): Fix clang sanatizer warning.
6        - Sample: Fix unnecessary RAM consumption in case of 24 bit samples
7          (InternalDecompressionBuffer is no longer needed for 24 bit samples since
8          SVN r902 / libgig release 3.1.0).
9    
10      * src/SF.cpp, src/SF.h:
11        - File::DeleteInstrument(): Fix clang sanatizer warning.
12    
13      * src/RIFF.cpp, src/RIFF.h:
14        - Chunk::LoadChunkData(): Fix clang sanatizer warning.
15        - List::LoadSubChunks(): Fix potential garbage data access if reading a
16          RIFF chunk ID failed.
17        - Added methods File::IsIOPerThread() and File::SetIOPerThread(bool); the
18          latter allows to automatically use a separate file I/O stream state for
19          each thread.
20        - Added method List::GetSubChunkAt().
21        - Added method List::GetSubListAt().
22        - Marked methods List::GetFirstSubChunk(), List::GetNextSubChunk(),
23          List::GetFirstSubList() and List::GetNextSubList() as deprecated.
24    
25    Version 4.3.0 (9 May 2021)
26    
27      * general changes:
28        - Require at least a C++11 compliant compiler.
29        - Require some UUID generating function by underlying system.
30    
31      * src/gig.cpp, src/gig.h:
32        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
33          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
34          allow to define override LFOs' wave form (e.g. saw or square instead of
35          the default wave form which was always sine in the original
36          Gigasampler/GigaStudio software).
37        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
38          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
39          move the start point horizontally of the LFOs' waves (0° ... 360°).
40        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
41          (the original Gigasampler/GigaStudio software only had that flip phase
42          option for LFO1 and LFO2).
43        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
44          Region::UsesAnyGigFormatExtension(),
45          Instrument::UsesAnyGigFormatExtension() and
46          File::UsesAnyGigFormatExtension() (however only as private methods yet,
47          see comments on methods why).
48        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
49          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
50          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
51          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
52          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
53        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
54          (patch by Ivan Maguidhir).
55        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
56          (original patch by Ivan Maguidhir).
57        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
58          dimensions being in different order after deleting a dimension zone.
59        - Script: Generate a persistent UUID for each script.
60        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
61          accordingly added new methods to Instrument class:
62          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
63          GetScriptPatchVariable(), SetScriptPatchVariable(),
64          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
65          as child of our '3LS ' list chunk on Instrument level.
66        - Fixed undefined behaviour when modifying script slots on an instrument
67          that had been cloned and not been saved yet (e.g. unintended modification
68          of original instrument's script slots, and crash on Instrument destruction
69          due to double free of pScriptRefs).
70    
71      * src/Serialization.cpp, src/Serialization.h:
72        - Fixed broken Archive(RawData) constructor which always threw an
73          Exception.
74        - Added built-in support for C++ String objects (a.k.a. std::string
75          from the STL) and bumped Srx format version to 1.1 for that reason.
76        - Fixed assertion fault on some systems if a member variable defined was
77          serialized which was declared as size_t or ssize_t data type.
78        - Added new method Archive::operation() which allows applications to
79          distinguish between serialization vs. deserialization in their
80          serialize() method implementations.
81        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
82          the STL).
83        - Member offsets are now signed and for (newly added support of) member
84          variables on the heap -1 is always used as offset instead.
85        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
86          STL).
87        - DataType: Added optional 2nd custom type name.
88        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
89          STL).
90    
91      * src/helper.h:
92        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
93          function call.
94    
95      * src/tools/gigdump.cpp:
96        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
97          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
98          LFO2FlipPhase and LFO3FlipPhase.
99    
100    Version 4.2.0 (25 Jul 2019)
101    
102      * general changes:
103        - Added MSVC build support (anonymous patch from mailing list).
104        - Introduced CMake build support (yet constrained for building with MSVC)
105          (anonymous patch from mailing list).
106        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
107          destructors. Added new virtual method DeleteChunks() to those classes
108          for this which must be explicitly called instead to remove their RIFF
109          chunks.
110        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
111          of zero; which is unsafe per se.
112        - Added C++11 "override" keyword where appropriate.
113        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
114          of their actions when not passing a progress_t callback structure.
115    
116      * src/gig.cpp, src/gig.h:
117        - Fixed Doxygen API comments for enum types (currently latest Doxygen
118          [v1.8.13] only supports C comments in macro arguments expansion, but
119          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
120          the Doxygen source code, which currently also filter out new line
121          \n chars).
122        - Added new method File::CountSamples().
123        - Added new method File::CountInstruments().
124        - Fixed gig v4 files falsely being handled as v2 format
125          (patch by Ivan Maguidhir).
126        - Added gig v4 version identifier (File::VERSION_4).
127        - GIG FORMAT EXTENSION: Added attribute
128          DimensionRegion::SustainReleaseTrigger which allows to define whether
129          a sustain pedal up event shall cause a release trigger sample to be
130          played (default: don't play release trigger sample by sustain pedal).
131        - GIG FORMAT EXTENSION: Added attribute
132          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
133          regular behaviour of playing release trigger sample on MIDI note-off
134          events.
135        - Introduced support for writing extension files (.gx01, .gx02, ...)
136          (original patch by Ivan Maguidhir).
137        - Many gig classes derive now from DLS::Storage (see DLS changes below).
138        - Added File::GetRiffFile() method.
139    
140      * src/DLS.cpp, src/DLS.h:
141        - File: Fixed implicitly allocated RIFF::File object never been freed.
142        - Added new abstract interface base class DLS::Storage which is derived by
143          the respective classes for implementing (the old) UpdateChunks() and the
144          new DeleteChunks() method.
145        - Added File::GetRiffFile() method.
146    
147      * src/sf2.cpp, src/sf2.h:
148        - Added Sample::GetFile() method.
149        - Added File::GetRiffFile() method.
150    
151      * src/Serialization.cpp, src/Serialization.h:
152        - Hide pure internal declarations from header file to avoid numerous
153          compiler warnings when building and linking against the public API.
154        - Fixed comparision logic bug
155        - Fixed memory leak in DataType::customTypeName().
156    
157      * src/RIFF.cpp, src/RIFF.h:
158        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
159          caused a resource leak
160        - Avoid compiler warning when building for 32 bit windows.
161        - Added new method progress_t::subdivide().
162        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
163        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
164          allows a more fine graded control into which portions the subtasks are
165          divided to.
166    
167      * src/tools/gigdump.cpp:
168        - Added command line option --instrument-names which causes only
169          instrument names and their index numbers to be printed.
170    
171    Version 4.1.0 (25 Nov 2017)
172      * general changes:
173        - removed 2 GB limitation when loading a gig or DLS file
174        - using now native integer size where appropriate
175        - fixed minor issues with man pages (patch by Debian maintainer)
176        - fixed various spelling mistakes (patch by Debian maintainer)
177        - Added new "Serialization" framework (and equally named namespace)
178          which allows to serialize and deserialize native C++ objects
179          in a portable, easy and flexible way.
180        - print compiler warning if no RTTI available
181        - Fixed potential crash in command line tools gig2stereo, korg2gig,
182          korgdump and sf2extract.
183        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
184          (original patch by Paul Brossier, slightly modified).
185        - Debian: Fixed packaging error about invalid substitution variable
186          "Source-Version".
187        - Raised Debian compatibility level to Debian 9 "Stretch".
188    
189      * src/gig.cpp, src/gig.h:
190        - fixed bug in Script::SetGroup: the script chunk wasn't moved
191        - fixed compilation error with clang 3.4
192        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
193          as one single monolithic gig file. In case .gig file is >= 2GB expect a
194          large monolithic file, otherwise if .gig file is < 2 GB check for
195          "extension" files (.gx01, .gx02, ...) instead.
196        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
197          if there were dimensions after the velocity dimension: it only created
198          valid velocity tables for cases of dimensions lower than the velocity
199          dimension.
200        - added new method Sample::VerifyWaveData() which allows to check whether
201          a sample had been damaged for some reason
202        - Fix: samples' CRC checksums were damaged on file structure changes.
203        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
204        - Added new method Sample::GetWaveDataCRC32Checksum().
205        - Changed default value of EG2Release (filter release time) to 60s.
206        - Instruments' default pitch bend range is now +-2 semi tones.
207        - Fixed CRC checksums being wrong sometimes.
208        - Fix: method File::AddContentOf() did not clone script groups and scripts
209          of passed original file.
210        - Added support for serializing & deserializing DimensionRegion
211          objects (and crossfade_t and leverage_ctrl_t objects).
212        - Added enum reflection API functions for retrieving enum declaration type
213          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
214        - Exception class now has a variadic constructor which allows to add
215          textual format specifiers like with printf().
216        - On unknown leverage controller exception: show precise unknown leverage
217          controller number found.
218        - Ignore invalid leverage controller types and just show a warning on the
219          console instead of throwing an exception.
220        - Added new struct eg_opt_t and new class member variable
221          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
222          extension to the gig file format, which allows to override the default
223          behavior of the first two EGs' state machines.
224        - Fixed undefined behavior when loading a gig file with invalid
225          velocity curve parameters (fixes CVE-2017-12951).
226        - Fixed undefined behavior when loading a gig file with invalid wave
227          pool index number (fixes CVE-2017-12954).
228    
229      * src/DLS.cpp, src/DLS.h:
230        - Sample: wave pool offsets are now 64 bits (to allow support for files
231          larger than 4 GB).
232        - Exception class now has a variadic constructor which allows to add
233          textual format specifiers like with printf().
234    
235      * src/RIFF.cpp, src/RIFF.h:
236        - added support for RIFF files larger than 4 GB, by default the required
237          internal RIFF file offset size is automatically detected (that is RIFF
238          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
239          automatically use 64 bit offsets), a particular offset size can be forced
240          with a new option added to the RIFF File constructor though
241        - when saving a modified, grown RIFF file, the temporary file size during
242          Save() operation will no longer be larger than the final grown file size
243        - Exception class now has a variadic constructor which allows to add
244          textual format specifiers like with printf().
245    
246      * src/Serialization.cpp, src/Serialization.h:
247        - Archive: Added method isModified().
248        - Archive: Added method setAutoValue().
249        - Archive: Added method setIntValue().
250        - Archive: Added method setRealValue().
251        - Archive: Added method setBoolValue().
252        - Archive: Added method setEnumValue().
253        - Archive: Added method valueAsString().
254        - Archive::rawData(): Automatically re-encode new raw data stream if
255          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
256        - Object: Added method memberByUID().
257        - Object: remove() method is now protected.
258        - Archive: Added method removeMember().
259        - Archive: Added methods name() and setName().
260        - Archive: Added methods comment() and setComment().
261        - Archive: Added methods timeStampCreated(), timeStampModified(),
262          dateTimeCreated() and dateTimeModified().
263        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
264        - DataType: Implemented demangling C++ type names (for methods
265          asLongDescr() and customTypeName(bool demangle=false)).
266        - Archive::setAutoValue(): Handle human readable boolean text
267          representations like "yes", "no", "true", "false" as expected.
268        - Exception class now has a variadic constructor which allows to add
269          textual format specifiers like with printf().
270        - DataType fix: Retain backward compatibility to older versions of native
271          C++ classes/structs.
272    
273      * src/Akai.cpp:
274        - Fixed compilation error with recent, more strict compilers.
275    
276      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:

278        - fixed printf format strings
279    
280      * src/tools/korg2gig.cpp:
281        - fixed c++11 narrowing warnings
282        - fixed fine tuning which was not translated at all
283    
284      * src/tools/gigdump.cpp:
285        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
286          dimension regions
287        - additionally print RIFF chunk file offset and RIFF chunk size of sample
288          data
289        - added and implemented new parameter "--verify" which allows to check
290          the raw wave form data integrity of all samples
291        - added and implemented new parameter "--rebuild-checksums" which allows
292          to recalculate the CRC32 checksum of all samples' raw wave data and
293          rebuilding the gig file's global checksum table (i.e. in case the
294          file's checksum table was damaged)
295        - print samples' CRC32 checksums
296        - Print the new EG behavior options (eg_opt_t).
297    
298      * src/tools/gigextract.cpp:
299        - Fix: if sample name contains a path separator (slash or backslash) then
300          replace them by a minus sign to avoid file system issues.
301    
302      * src/tools/gig2stereo.cpp:
303        - Also merge mono sample pairs with non matching loop information if
304          argument --incompatible was given.
305    
306      * packaging changes:
307        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
308          auto detect whether it (sh/c)ould output its messages in color.
309
