preparations for release 2.0.0

1 schoenebeck 530 Version 2.0.0 (9 May 2005)
2 schoenebeck 317
3 schoenebeck 383 * packaging changes:
4     - fixed conditional linkage of either libsndfile or libaudiofile
5     (if none of the two exist, configure script will abort)
6 schoenebeck 518 - man pages are now auto generated with the correct libgig version
7 schoenebeck 383
8 schoenebeck 317 * src/gig.cpp, src/gig.h:
9     - experimental support for Gigasampler v3 format;
10     64 bit file offsets are truncated to 32 bit, 24 bit samples are
11 schoenebeck 347 truncated to 16 bit, up to 8 dimensions are read, additional
12     articulation informations are ignored at the moment
13     (patch by Andreas Persson)
14 schoenebeck 317 - added some file format compatibility checks
15 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
16     never used, because the necessary check was made before
17     initialization)
18     - fixed crossfade points order (structure for big endian and little
19     endian systems was interchanged)
20 schoenebeck 355 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
21 schoenebeck 352 - fixed crash which occured when patches did not have a sample assigned
22     to their region or dimension region (patch by Andreas Persson)
23 persson 365 - support for compressed mono samples
24     - experimental support for compressed 24 bit samples
25     - fixed decompression on big-endian CPUs
26     - fixed decompression bug that truncated the last block of samples
27 schoenebeck 384 - external decompression buffers can now be used for streaming samples
28     to avoid race conditions in case of multiple streaming threads
29 persson 406 - added pre-calculated sample attenuation parameter
30 persson 437 - added v3 "random" and "round robin" dimensions
31 schoenebeck 515 - implemented progress indicator callback mechanism for loading
32     instruments and samples
33 schoenebeck 518 - added functions libraryName() and libraryVersion()
34 schoenebeck 317
35 schoenebeck 518 * src/DLS.cpp, src/DLS.h:
36 schoenebeck 515 - fixed File constructor which caused variable File::Instruments always
37     to be zero
38 schoenebeck 518 - added functions libraryName() and libraryVersion()
39 schoenebeck 515
40 schoenebeck 518 * src/RIFF.cpp, src/RIFF.h:
41 schoenebeck 515 - fixed method List::LoadSubChunks() which did not restore the original
42     position within the body of the given list chunk
43 schoenebeck 518 - added functions libraryName() and libraryVersion()
44 schoenebeck 515
45 schoenebeck 518 * src/rifftree.cpp:

60     - support for compressed mono samples and compressed 24 bit samples
61 schoenebeck 518 - added command line switch -v to show gigextract's revision and the
62     used libgig version
63 persson 365
64 schoenebeck 315 Version 1.0.0 (26 Nov 2004)
65 schoenebeck 196
66     * packaging changes:
67     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
68     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
69 schoenebeck 315 - fixed man pages automake install rule (which didn't work on Mandrake,
70     SuSE and Fedora)
71     - fixed generation of Doxygen API documentation (now also included in
72     RPM and Debian packages)
73 schoenebeck 196
74 schoenebeck 231 * src/gig.cpp, src/gig.h:
75     - fixed / improved accuracy of all three velocity to volume
76 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
77     (patch by Andreas Persson)
78 schoenebeck 231 - denormals are filtered from the velocity to volume tables
79 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
80     trigger dimension, no bit range check for dimensions of split type
81     'split_type_bit')
82 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
83     signed 7 bit to signed 8 bit)
84 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
85 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
86 schoenebeck 231
87 schoenebeck 220 * src/gigextract.cpp:
88     - added support for libsndfile (if libaudiofile and libsndfile are
89     available then libsndfile is preferred)
90    
91 schoenebeck 229 * src/gigdump.cpp:
92     - added printout for dimension informations (amount, type, bits, zones)
93 schoenebeck 231 - added printout for velocity response curve parameters
94 schoenebeck 235 - added printout for crossfade definitions
95 schoenebeck 269 - added printout for panorama value for each DimensionRegion
96 schoenebeck 282 - replaced printout of DLS Region layer by printout of amount of
97     Gigasampler layers
98 schoenebeck 229
99 capela 168 Version 0.7.1 (2 Jul 2004)
100    
101     * packaging changes:
102 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
103     Redhat packages
104 capela 168 - header files included on installation.
105     - autotools-generated files removed from CVS repository.
106 schoenebeck 186 - added support for generating Debian packages
107     - version of shared library can be set in configure.in
108    
109 schoenebeck 58 Version 0.7.0 (3 May 2004)
110    
111     * general changes:
112     - various big endian specific corrections
113     (successfully tested now on PPC)
114     - minor adjustments to avoid compile errors on some systems
115     (using now pow() instead of powl() and --pedantic g++ compiler switch)
116     - libtoolized the library
117     - added man pages for the command line tools
118     (gigextract, gigdump, dlsdump, rifftree)
119    
120     * src/gig.cpp, src/gig.h:
121     - fixed bug in decompression algorithm which caused it not to detect
122     the end of a stream
123     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
124     takes the MIDI key velocity value as an argument and returns the
125     appropriate volume factor (0.0 ... 1.0) for the sample to be played
126     back, the velocity curve transformation functions used for this are
127     only an approximation so far
128     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
129     'Sample::LoopSize' which reflected wrong values
130     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
131     measured in sample points instead of byte offset
132     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
133     'Sample::FineTune'
134     - added class attribute 'Sample::LoopSize'
135     - added method GetInstrument(uint index) to class 'File'
136     - added ReadAndLoop() method to class 'Sample' which is an extension to
137     the normal Read() method to honor the sample's looping information
138     while streaming from disk
139     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
140     'eg2_ctrl_t': replaced this huge enumeration by a structure which
141     reflects the MIDI controller number in case of an ordinary control
142     change controller (this saves a huge switch-case block in the
143     application of the library user)
144     - renamed following attributes in class 'DimensionRegion':
145     'AttenuationContol' -> 'AttenuationController',
146     'InvertAttenuationControl' -> 'InvertAttenuationController',
147     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
148     - minor fix in API documentation for method GetVelocityAttenuation() in
149     class 'DimensionRegion'
150    
151     * src/RIFF.cpp, src/RIFF.h:
152     - added additional API documentation
153     - minor fix in Chunk::Read() method (only a minor efficiency issue)
154    
155     * src/gigdump.cpp:
156     - added printout of samples' looping informations
157    
158 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
159    
160     * initial release
