1  Version CVS HEAD (?)  Version SVN trunk (?)
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    
43      * src/Serialization.cpp, src/Serialization.h:
44        - Fixed broken Archive(RawData) constructor which always threw an
45          Exception.
46        - Added built-in support for C++ String objects (a.k.a. std::string
47          from the STL) and bumped Srx format version to 1.1 for that reason.
48    
49      * src/tools/gigdump.cpp:
50        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
51          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
52          LFO2FlipPhase and LFO3FlipPhase.
53    
54    Version 4.2.0 (25 Jul 2019)
55    
56      * general changes:
57        - Added MSVC build support (anonymous patch from mailing list).
58        - Introduced CMake build support (yet constrained for building with MSVC)
59          (anonymous patch from mailing list).
60        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
61          destructors. Added new virtual method DeleteChunks() to those classes
62          for this which must be explicitly called instead to remove their RIFF
63          chunks.
64        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
65          of zero; which is unsafe per se.
66        - Added C++11 "override" keyword where appropriate.
67        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
68          of their actions when not passing a progress_t callback structure.
69    
70      * src/gig.cpp, src/gig.h:
71        - Fixed Doxygen API comments for enum types (currently latest Doxygen
72          [v1.8.13] only supports C comments in macro arguments expansion, but
73          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
74          the Doxygen source code, which currently also filter out new line
75          \n chars).
76        - Added new method File::CountSamples().
77        - Added new method File::CountInstruments().
78        - Fixed gig v4 files falsely being handled as v2 format
79          (patch by Ivan Maguidhir).
80        - Added gig v4 version identifier (File::VERSION_4).
81        - GIG FORMAT EXTENSION: Added attribute
82          DimensionRegion::SustainReleaseTrigger which allows to define whether
83          a sustain pedal up event shall cause a release trigger sample to be
84          played (default: don't play release trigger sample by sustain pedal).
85        - GIG FORMAT EXTENSION: Added attribute
86          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
87          regular behaviour of playing release trigger sample on MIDI note-off
88          events.
89        - Introduced support for writing extension files (.gx01, .gx02, ...)
90          (original patch by Ivan Maguidhir).
91        - Many gig classes derive now from DLS::Storage (see DLS changes below).
92        - Added File::GetRiffFile() method.
93    
94      * src/DLS.cpp, src/DLS.h:
95        - File: Fixed implicitly allocated RIFF::File object never been freed.
96        - Added new abstract interface base class DLS::Storage which is derived by
97          the respective classes for implementing (the old) UpdateChunks() and the
98          new DeleteChunks() method.
99        - Added File::GetRiffFile() method.
100    
101      * src/sf2.cpp, src/sf2.h:
102        - Added Sample::GetFile() method.
103        - Added File::GetRiffFile() method.
104    
105      * src/Serialization.cpp, src/Serialization.h:
106        - Hide pure internal declarations from header file to avoid numerous
107          compiler warnings when building and linking against the public API.
108        - Fixed comparision logic bug
109        - Fixed memory leak in DataType::customTypeName().
110    
111      * src/RIFF.cpp, src/RIFF.h:
112        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
113          caused a resource leak
114        - Avoid compiler warning when building for 32 bit windows.
115        - Added new method progress_t::subdivide().
116        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
117        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
118          allows a more fine graded control into which portions the subtasks are
119          divided to.
120    
121      * src/tools/gigdump.cpp:
122        - Added command line option --instrument-names which causes only
123          instrument names and their index numbers to be printed.
124    
125    Version 4.1.0 (25 Nov 2017)
126      * general changes:
127        - removed 2 GB limitation when loading a gig or DLS file
128        - using now native integer size where appropriate
129        - fixed minor issues with man pages (patch by Debian maintainer)
130        - fixed various spelling mistakes (patch by Debian maintainer)
131        - Added new "Serialization" framework (and equally named namespace)
132          which allows to serialize and deserialize native C++ objects
133          in a portable, easy and flexible way.
134        - print compiler warning if no RTTI available
135        - Fixed potential crash in command line tools gig2stereo, korg2gig,
136          korgdump and sf2extract.
137        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
138          (original patch by Paul Brossier, slightly modified).
139        - Debian: Fixed packaging error about invalid substitution variable
140          "Source-Version".
141        - Raised Debian compatibility level to Debian 9 "Stretch".
142    
143      * src/gig.cpp, src/gig.h:
144        - fixed bug in Script::SetGroup: the script chunk wasn't moved
145        - fixed compilation error with clang 3.4
146        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
147          as one single monolithic gig file. In case .gig file is >= 2GB expect a
148          large monolithic file, otherwise if .gig file is < 2 GB check for
149          "extension" files (.gx01, .gx02, ...) instead.
150        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
151          if there were dimensions after the velocity dimension: it only created
152          valid velocity tables for cases of dimensions lower than the velocity
153          dimension.
154        - added new method Sample::VerifyWaveData() which allows to check whether
155          a sample had been damaged for some reason
156        - Fix: samples' CRC checksums were damaged on file structure changes.
157        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
158        - Added new method Sample::GetWaveDataCRC32Checksum().
159        - Changed default value of EG2Release (filter release time) to 60s.
160        - Instruments' default pitch bend range is now +-2 semi tones.
161        - Fixed CRC checksums being wrong sometimes.
162        - Fix: method File::AddContentOf() did not clone script groups and scripts
163          of passed original file.
164        - Added support for serializing & deserializing DimensionRegion
165          objects (and crossfade_t and leverage_ctrl_t objects).
166        - Added enum reflection API functions for retrieving enum declaration type
167          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
168        - Exception class now has a variadic constructor which allows to add
169          textual format specifiers like with printf().
170        - On unknown leverage controller exception: show precise unknown leverage
171          controller number found.
172        - Ignore invalid leverage controller types and just show a warning on the
173          console instead of throwing an exception.
174        - Added new struct eg_opt_t and new class member variable
175          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
176          extension to the gig file format, which allows to override the default
177          behavior of the first two EGs' state machines.
178        - Fixed undefined behavior when loading a gig file with invalid
179          velocity curve parameters (fixes CVE-2017-12951).
180        - Fixed undefined behavior when loading a gig file with invalid wave
181          pool index number (fixes CVE-2017-12954).
182    
183      * src/DLS.cpp, src/DLS.h:
184        - Sample: wave pool offsets are now 64 bits (to allow support for files
185          larger than 4 GB).
186        - Exception class now has a variadic constructor which allows to add
187          textual format specifiers like with printf().
188    
189      * src/RIFF.cpp, src/RIFF.h:
190        - added support for RIFF files larger than 4 GB, by default the required
191          internal RIFF file offset size is automatically detected (that is RIFF
192          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
193          automatically use 64 bit offsets), a particular offset size can be forced
194          with a new option added to the RIFF File constructor though
195        - when saving a modified, grown RIFF file, the temporary file size during
196          Save() operation will no longer be larger than the final grown file size
197        - Exception class now has a variadic constructor which allows to add
198          textual format specifiers like with printf().
199    
200      * src/Serialization.cpp, src/Serialization.h:
201        - Archive: Added method isModified().
202        - Archive: Added method setAutoValue().

206        - Archive: Added method setEnumValue().
207        - Archive: Added method valueAsString().
208        - Archive::rawData(): Automatically re-encode new raw data stream if
209          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
210        - Object: Added method memberByUID().
211        - Object: remove() method is now protected.
212        - Archive: Added method removeMember().
213        - Archive: Added methods name() and setName().
214        - Archive: Added methods comment() and setComment().
215        - Archive: Added methods timeStampCreated(), timeStampModified(),
216          dateTimeCreated() and dateTimeModified().
217        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
218        - DataType: Implemented demangling C++ type names (for methods
219          asLongDescr() and customTypeName(bool demangle=false)).
220        - Archive::setAutoValue(): Handle human readable boolean text
221          representations like "yes", "no", "true", "false" as expected.
222        - Exception class now has a variadic constructor which allows to add
223          textual format specifiers like with printf().
224        - DataType fix: Retain backward compatibility to older versions of native
225          C++ classes/structs.
226    
227      * src/Akai.cpp:

238      * src/tools/gigdump.cpp:
239        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
240          dimension regions
241        - additionally print RIFF chunk file offset and RIFF chunk size of sample
242          data
243        - added and implemented new parameter "--verify" which allows to check
244          the raw wave form data integrity of all samples
245        - added and implemented new parameter "--rebuild-checksums" which allows
246          to recalculate the CRC32 checksum of all samples' raw wave data and
247          rebuilding the gig file's global checksum table (i.e. in case the
248          file's checksum table was damaged)
249        - print samples' CRC32 checksums
250        - Print the new EG behavior options (eg_opt_t).
251    
252      * src/tools/gigextract.cpp:
253        - Fix: if sample name contains a path separator (slash or backslash) then
254          replace them by a minus sign to avoid file system issues.
255    
256      * src/tools/gig2stereo.cpp:
257        - Also merge mono sample pairs with non matching loop information if
258          argument --incompatible was given.
259    
260      * packaging changes:
261        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
262          auto detect whether it (sh/c)ould output its messages in color.
