# Line 1  Line 1 
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    
37      * src/tools/gigdump.cpp:
38        - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
39          LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
40          LFO2FlipPhase and LFO3FlipPhase.
41    
42    Version 4.2.0 (25 Jul 2019)
43    
44      * general changes:
45        - Added MSVC build support (anonymous patch from mailing list).
46        - Introduced CMake build support (yet constrained for building with MSVC)
47          (anonymous patch from mailing list).
48        - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
49          destructors. Added new virtual method DeleteChunks() to those classes
50          for this which must be explicitly called instead to remove their RIFF
51          chunks.
52        - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
53          of zero; which is unsafe per se.
54        - Added C++11 "override" keyword where appropriate.
55        - Fixed crash in RIFF, DLS and gig classes which occurred on certain
56          of their actions when not passing a progress_t callback structure.
57    
58      * src/gig.cpp, src/gig.h:
59        - Fixed Doxygen API comments for enum types (currently latest Doxygen
60          [v1.8.13] only supports C comments in macro arguments expansion, but
61          not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
62          the Doxygen source code, which currently also filter out new line
63          \n chars).
64        - Added new method File::CountSamples().
65        - Added new method File::CountInstruments().
66        - Fixed gig v4 files falsely being handled as v2 format
67          (patch by Ivan Maguidhir).
68        - Added gig v4 version identifier (File::VERSION_4).
69        - GIG FORMAT EXTENSION: Added attribute
70          DimensionRegion::SustainReleaseTrigger which allows to define whether
71          a sustain pedal up event shall cause a release trigger sample to be
72          played (default: don't play release trigger sample by sustain pedal).
73        - GIG FORMAT EXTENSION: Added attribute
74          DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
75          regular behaviour of playing release trigger sample on MIDI note-off
76          events.
77        - Introduced support for writing extension files (.gx01, .gx02, ...)
78          (original patch by Ivan Maguidhir).
79        - Many gig classes derive now from DLS::Storage (see DLS changes below).
80        - Added File::GetRiffFile() method.
81    
82      * src/DLS.cpp, src/DLS.h:
83        - File: Fixed implicitly allocated RIFF::File object never been freed.
84        - Added new abstract interface base class DLS::Storage which is derived by
85          the respective classes for implementing (the old) UpdateChunks() and the
86          new DeleteChunks() method.
87        - Added File::GetRiffFile() method.
88    
89      * src/sf2.cpp, src/sf2.h:
90        - Added Sample::GetFile() method.
91        - Added File::GetRiffFile() method.
92    
93      * src/Serialization.cpp, src/Serialization.h:
94        - Hide pure internal declarations from header file to avoid numerous
95          compiler warnings when building and linking against the public API.
96        - Fixed comparision logic bug
97        - Fixed memory leak in DataType::customTypeName().
98    
99      * src/RIFF.cpp, src/RIFF.h:
100        - Fix: Calling File::SetMode() left an undefined file handle on Windows and
101          caused a resource leak
102        - Avoid compiler warning when building for 32 bit windows.
103        - Added new method progress_t::subdivide().
104        - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
105        - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
106          allows a more fine graded control into which portions the subtasks are
107          divided to.
108    
109      * src/tools/gigdump.cpp:
110        - Added command line option --instrument-names which causes only
111          instrument names and their index numbers to be printed.
112    
113    Version 4.1.0 (25 Nov 2017)
114      * general changes:
115        - removed 2 GB limitation when loading a gig or DLS file
116        - using now native integer size where appropriate
117        - fixed minor issues with man pages (patch by Debian maintainer)
118        - fixed various spelling mistakes (patch by Debian maintainer)
119        - Added new "Serialization" framework (and equally named namespace)
120          which allows to serialize and deserialize native C++ objects
121          in a portable, easy and flexible way.
122        - print compiler warning if no RTTI available
123        - Fixed potential crash in command line tools gig2stereo, korg2gig,
124          korgdump and sf2extract.
125        - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
126          (original patch by Paul Brossier, slightly modified).
127        - Debian: Fixed packaging error about invalid substitution variable
128          "Source-Version".
129        - Raised Debian compatibility level to Debian 9 "Stretch".
130    
131      * src/gig.cpp, src/gig.h:
132        - fixed bug in Script::SetGroup: the script chunk wasn't moved
133        - fixed compilation error with clang 3.4
134        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
135          as one single monolithic gig file. In case .gig file is >= 2GB expect a
136          large monolithic file, otherwise if .gig file is < 2 GB check for
137          "extension" files (.gx01, .gx02, ...) instead.
138        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
139          if there were dimensions after the velocity dimension: it only created
140          valid velocity tables for cases of dimensions lower than the velocity
141          dimension.
142        - added new method Sample::VerifyWaveData() which allows to check whether
143          a sample had been damaged for some reason
144        - Fix: samples' CRC checksums were damaged on file structure changes.
145        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
146        - Added new method Sample::GetWaveDataCRC32Checksum().
147        - Changed default value of EG2Release (filter release time) to 60s.
148        - Instruments' default pitch bend range is now +-2 semi tones.
149        - Fixed CRC checksums being wrong sometimes.
150        - Fix: method File::AddContentOf() did not clone script groups and scripts
151          of passed original file.
152        - Added support for serializing & deserializing DimensionRegion
153          objects (and crossfade_t and leverage_ctrl_t objects).
154        - Added enum reflection API functions for retrieving enum declaration type
155          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
156        - Exception class now has a variadic constructor which allows to add
157          textual format specifiers like with printf().
158        - On unknown leverage controller exception: show precise unknown leverage
159          controller number found.
160        - Ignore invalid leverage controller types and just show a warning on the
161          console instead of throwing an exception.
162        - Added new struct eg_opt_t and new class member variable
163          DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
164          extension to the gig file format, which allows to override the default
165          behavior of the first two EGs' state machines.
166        - Fixed undefined behavior when loading a gig file with invalid
167          velocity curve parameters (fixes CVE-2017-12951).
168        - Fixed undefined behavior when loading a gig file with invalid wave
169          pool index number (fixes CVE-2017-12954).
170    
171      * src/DLS.cpp, src/DLS.h:
172        - Sample: wave pool offsets are now 64 bits (to allow support for files
173          larger than 4 GB).
174        - Exception class now has a variadic constructor which allows to add
175          textual format specifiers like with printf().
176    
177      * src/RIFF.cpp, src/RIFF.h:
178        - added support for RIFF files larger than 4 GB, by default the required
179          internal RIFF file offset size is automatically detected (that is RIFF
180          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
181          automatically use 64 bit offsets), a particular offset size can be forced
182          with a new option added to the RIFF File constructor though
183        - when saving a modified, grown RIFF file, the temporary file size during
184          Save() operation will no longer be larger than the final grown file size
185        - Exception class now has a variadic constructor which allows to add
186          textual format specifiers like with printf().
187    
188      * src/Serialization.cpp, src/Serialization.h:
189        - Archive: Added method isModified().

197          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
198        - Object: Added method memberByUID().
199        - Object: remove() method is now protected.
200        - Archive: Added method removeMember().
201        - Archive: Added methods name() and setName().
202        - Archive: Added methods comment() and setComment().
203        - Archive: Added methods timeStampCreated(), timeStampModified(),
204          dateTimeCreated() and dateTimeModified().
205        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
206        - DataType: Implemented demangling C++ type names (for methods
207          asLongDescr() and customTypeName(bool demangle=false)).
208        - Archive::setAutoValue(): Handle human readable boolean text
209          representations like "yes", "no", "true", "false" as expected.
210        - Exception class now has a variadic constructor which allows to add
211          textual format specifiers like with printf().

227        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
228          dimension regions
229        - additionally print RIFF chunk file offset and RIFF chunk size of sample
230          data
231        - added and implemented new parameter "--verify" which allows to check
232          the raw wave form data integrity of all samples
233        - added and implemented new parameter "--rebuild-checksums" which allows
234          to recalculate the CRC32 checksum of all samples' raw wave data and
235          rebuilding the gig file's global checksum table (i.e. in case the
236          file's checksum table was damaged)
237        - print samples' CRC32 checksums
238        - Print the new EG behavior options (eg_opt_t).
