# Line 1  Line 1 
1  Version CVS HEAD (?)  Version 4.3.0 (9 May 2021)
2    
3      * general changes:
4        - Require at least a C++11 compliant compiler.
5        - Require some UUID generating function by underlying system.
6    
7      * src/gig.cpp, src/gig.h:
8        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
9          DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
10          allow to define override LFOs' wave form (e.g. saw or square instead of
11          the default wave form which was always sine in the original
12          Gigasampler/GigaStudio software).
13        - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
14          DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
15          move the start point horizontally of the LFOs' waves (0° ... 360°).
16        - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
17          (the original Gigasampler/GigaStudio software only had that flip phase
18          option for LFO1 and LFO2).
19        - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
20          Region::UsesAnyGigFormatExtension(),
21          Instrument::UsesAnyGigFormatExtension() and
22          File::UsesAnyGigFormatExtension() (however only as private methods yet,
23          see comments on methods why).
24        - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
25          implementations to enum vcf_type_t: vcf_type_lowpass_1p,
26          vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
27          vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
28          vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
29        - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
30          (patch by Ivan Maguidhir).
31        - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
32          (original patch by Ivan Maguidhir).
33        - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
34          dimensions being in different order after deleting a dimension zone.
35        - Script: Generate a persistent UUID for each script.
36        - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
37          accordingly added new methods to Instrument class:
38          IsScriptPatchVariableSet(), GetScriptPatchVariables(),
39          GetScriptPatchVariable(), SetScriptPatchVariable(),
40          UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
41          as child of our '3LS ' list chunk on Instrument level.
42        - Fixed undefined behaviour when modifying script slots on an instrument
43          that had been cloned and not been saved yet (e.g. unintended modification
44          of original instrument's script slots, and crash on Instrument destruction
45          due to double free of pScriptRefs).
46    
47      * src/Serialization.cpp, src/Serialization.h:
48        - Fixed broken Archive(RawData) constructor which always threw an
49          Exception.
50        - Added built-in support for C++ String objects (a.k.a. std::string
51          from the STL) and bumped Srx format version to 1.1 for that reason.
52        - Fixed assertion fault on some systems if a member variable defined was
53          serialized which was declared as size_t or ssize_t data type.
54        - Added new method Archive::operation() which allows applications to
55          distinguish between serialization vs. deserialization in their
56          serialize() method implementations.
57        - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
58          the STL).
59        - Member offsets are now signed and for (newly added support of) member
60          variables on the heap -1 is always used as offset instead.
61        - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
62          STL).
63        - DataType: Added optional 2nd custom type name.
64        - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
65          STL).
66    
67      * src/helper.h:
68        - Fix compile error with GCC 9 due to ignored result value of vasprintf()
69          function call.
70    
71      * src/tools/gigdump.cpp:
72        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
73          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
74          LFO2FlipPhase and LFO3FlipPhase.
75    
76    Version 4.2.0 (25 Jul 2019)
77    
78      * general changes:
79        - Added MSVC build support (anonymous patch from mailing list).
80        - Introduced CMake build support (yet constrained for building with MSVC)
81          (anonymous patch from mailing list).
82        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
83          destructors. Added new virtual method DeleteChunks() to those classes
84          for this which must be explicitly called instead to remove their RIFF
85          chunks.
86        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
87          of zero; which is unsafe per se.
88        - Added C++11 "override" keyword where appropriate.
89        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
90          of their actions when not passing a progress_t callback structure.
91    
92      * src/gig.cpp, src/gig.h:
93        - Fixed Doxygen API comments for enum types (currently latest Doxygen
94          [v1.8.13] only supports C comments in macro arguments expansion, but
95          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
96          the Doxygen source code, which currently also filter out new line
97          \n chars).
98        - Added new method File::CountSamples().
99        - Added new method File::CountInstruments().
100        - Fixed gig v4 files falsely being handled as v2 format
101          (patch by Ivan Maguidhir).
102        - Added gig v4 version identifier (File::VERSION_4).
103        - GIG FORMAT EXTENSION: Added attribute
104          DimensionRegion::SustainReleaseTrigger which allows to define whether
105          a sustain pedal up event shall cause a release trigger sample to be
106          played (default: don't play release trigger sample by sustain pedal).
107        - GIG FORMAT EXTENSION: Added attribute
108          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
109          regular behaviour of playing release trigger sample on MIDI note-off
110          events.
111        - Introduced support for writing extension files (.gx01, .gx02, ...)
112          (original patch by Ivan Maguidhir).
113        - Many gig classes derive now from DLS::Storage (see DLS changes below).
114        - Added File::GetRiffFile() method.
115    
116      * src/DLS.cpp, src/DLS.h:
117        - File: Fixed implicitly allocated RIFF::File object never been freed.
118        - Added new abstract interface base class DLS::Storage which is derived by
119          the respective classes for implementing (the old) UpdateChunks() and the
120          new DeleteChunks() method.
121        - Added File::GetRiffFile() method.
122    
123      * src/sf2.cpp, src/sf2.h:
124        - Added Sample::GetFile() method.
125        - Added File::GetRiffFile() method.
126    
127      * src/Serialization.cpp, src/Serialization.h:
128        - Hide pure internal declarations from header file to avoid numerous
129          compiler warnings when building and linking against the public API.
130        - Fixed comparision logic bug
131        - Fixed memory leak in DataType::customTypeName().
132    
133      * src/RIFF.cpp, src/RIFF.h:
134        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
135          caused a resource leak
136        - Avoid compiler warning when building for 32 bit windows.
137        - Added new method progress_t::subdivide().
138        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
139        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
140          allows a more fine graded control into which portions the subtasks are
141          divided to.
142    
143      * src/tools/gigdump.cpp:
144        - Added command line option --instrument-names which causes only
145          instrument names and their index numbers to be printed.
146    
147    Version 4.1.0 (25 Nov 2017)
148      * general changes:
149        - removed 2 GB limitation when loading a gig or DLS file
150        - using now native integer size where appropriate
151        - fixed minor issues with man pages (patch by Debian maintainer)
152        - fixed various spelling mistakes (patch by Debian maintainer)
153        - Added new "Serialization" framework (and equally named namespace)
154          which allows to serialize and deserialize native C++ objects
155          in a portable, easy and flexible way.
156        - print compiler warning if no RTTI available
157        - Fixed potential crash in command line tools gig2stereo, korg2gig,
158          korgdump and sf2extract.
159        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
160          (original patch by Paul Brossier, slightly modified).
161        - Debian: Fixed packaging error about invalid substitution variable
162          "Source-Version".
163        - Raised Debian compatibility level to Debian 9 "Stretch".
164    
165      * src/gig.cpp, src/gig.h:
166        - fixed bug in Script::SetGroup: the script chunk wasn't moved
167        - fixed compilation error with clang 3.4
168        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
169          as one single monolithic gig file. In case .gig file is >= 2GB expect a
170          large monolithic file, otherwise if .gig file is < 2 GB check for
171          "extension" files (.gx01, .gx02, ...) instead.
172        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
173          if there were dimensions after the velocity dimension: it only created
174          valid velocity tables for cases of dimensions lower than the velocity
175          dimension.
176        - added new method Sample::VerifyWaveData() which allows to check whether
177          a sample had been damaged for some reason
178        - Fix: samples' CRC checksums were damaged on file structure changes.
179        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
180        - Added new method Sample::GetWaveDataCRC32Checksum().
181        - Changed default value of EG2Release (filter release time) to 60s.
182        - Instruments' default pitch bend range is now +-2 semi tones.
183        - Fixed CRC checksums being wrong sometimes.
184        - Fix: method File::AddContentOf() did not clone script groups and scripts
185          of passed original file.
186        - Added support for serializing & deserializing DimensionRegion
187          objects (and crossfade_t and leverage_ctrl_t objects).
188        - Added enum reflection API functions for retrieving enum declaration type
189          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
190        - Exception class now has a variadic constructor which allows to add
191          textual format specifiers like with printf().
192        - On unknown leverage controller exception: show precise unknown leverage
193          controller number found.
194        - Ignore invalid leverage controller types and just show a warning on the
195          console instead of throwing an exception.
196        - Added new struct eg_opt_t and new class member variable
197          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
198          extension to the gig file format, which allows to override the default
199          behavior of the first two EGs' state machines.
200        - Fixed undefined behavior when loading a gig file with invalid
201          velocity curve parameters (fixes CVE-2017-12951).
202        - Fixed undefined behavior when loading a gig file with invalid wave
203          pool index number (fixes CVE-2017-12954).
204    
205      * src/DLS.cpp, src/DLS.h:
206        - Sample: wave pool offsets are now 64 bits (to allow support for files
207          larger than 4 GB).
208        - Exception class now has a variadic constructor which allows to add
209          textual format specifiers like with printf().
210    
211      * src/RIFF.cpp, src/RIFF.h:
212        - added support for RIFF files larger than 4 GB, by default the required
213          internal RIFF file offset size is automatically detected (that is RIFF
214          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
215          automatically use 64 bit offsets), a particular offset size can be forced
216          with a new option added to the RIFF File constructor though
217        - when saving a modified, grown RIFF file, the temporary file size during
218          Save() operation will no longer be larger than the final grown file size
219        - Exception class now has a variadic constructor which allows to add
220          textual format specifiers like with printf().
221    
222      * src/Serialization.cpp, src/Serialization.h:
223        - Archive: Added method isModified().
224        - Archive: Added method setAutoValue().
225        - Archive: Added method setIntValue().
226        - Archive: Added method setRealValue().
227        - Archive: Added method setBoolValue().
228        - Archive: Added method setEnumValue().
229        - Archive: Added method valueAsString().
230        - Archive::rawData(): Automatically re-encode new raw data stream if
231          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
232        - Object: Added method memberByUID().
233        - Object: remove() method is now protected.
234        - Archive: Added method removeMember().
235        - Archive: Added methods name() and setName().
236        - Archive: Added methods comment() and setComment().
237        - Archive: Added methods timeStampCreated(), timeStampModified(),
238          dateTimeCreated() and dateTimeModified().
239        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
240        - DataType: Implemented demangling C++ type names (for methods
241          asLongDescr() and customTypeName(bool demangle=false)).
242        - Archive::setAutoValue(): Handle human readable boolean text
243          representations like "yes", "no", "true", "false" as expected.
244        - Exception class now has a variadic constructor which allows to add
245          textual format specifiers like with printf().
246        - DataType fix: Retain backward compatibility to older versions of native
247          C++ classes/structs.
248    
249      * src/Akai.cpp:
250        - Fixed compilation error with recent, more strict compilers.
251    
252      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
253        - improved output of non-ascii characters in usage messages
254        - fixed printf format strings
255    
256      * src/tools/korg2gig.cpp:
257        - fixed c++11 narrowing warnings
258        - fixed fine tuning which was not translated at all
259    
260      * src/tools/gigdump.cpp:
261        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
262          dimension regions
263        - additionally print RIFF chunk file offset and RIFF chunk size of sample
264          data
265        - added and implemented new parameter "--verify" which allows to check
266          the raw wave form data integrity of all samples
267        - added and implemented new parameter "--rebuild-checksums" which allows
268          to recalculate the CRC32 checksum of all samples' raw wave data and
269          rebuilding the gig file's global checksum table (i.e. in case the
270          file's checksum table was damaged)
271        - print samples' CRC32 checksums
272        - Print the new EG behavior options (eg_opt_t).
273    
274      * src/tools/gigextract.cpp:
275        - Fix: if sample name contains a path separator (slash or backslash) then
276          replace them by a minus sign to avoid file system issues.
277    
278      * src/tools/gig2stereo.cpp:
279        - Also merge mono sample pairs with non matching loop information if
280          argument --incompatible was given.
281    
282      * packaging changes:
283        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
284          auto detect whether it (sh/c)ould output its messages in color.
