* src/RIFF.cpp :
    - bugfix: undefined behavior (e.g. endless loop) when opening zero
      length files, now throws a RIFF::Exception instead (fixes bug #121)

1 persson 1627 Version CVS HEAD (?)
2    
3 persson 1713 * general changes:
4     - fixed compilation with gcc 4.3
5    
6 persson 1627 * src/gig.cpp, src/gig.h:
7     - added partial support for MIDI rules, only the Controller
8     Triggered rule is supported so far
9 persson 1678 - bugfix: removed another iterator invalidation in DeleteSample
10 schoenebeck 1851 - bugfix in Sample::LoadSampleData*(): reset sample read position to
11     sample start before trying to (re)load sample data from file (#82)
12 persson 1627
13 persson 1678 * src/RIFF.cpp, src/RIFF.h:
14     - bugfix: saving to the same file after the file size had been
15     increased made the file corrupt (#82)
16 schoenebeck 1851 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
17     is not written physically yet (#82)
18 persson 1859 - bugfix: saving to the same file after the file size had been
19     decreased sometimes also made the file corrupt!
20 schoenebeck 1863 - bugfix: undefined behavior (e.g. endless loop) when opening zero
21     length files, now throws a RIFF::Exception instead (fixes bug #121)
22 persson 1678

24 schoenebeck 1459
25     * src/RIFF.cpp, src/RIFF.h:
26     - avoid Windows to perform unnecessary file stream caching which would
27     decrease disk streaming performance on Windows systems otherwise
28    
29 schoenebeck 1524 * src/gig.cpp, src/gig.h:
30     - added File::SetAutoLoad() and File::GetAutoLoad() for allowing

58     happened when gig::Group informations were accessed before
59 persson 1179 - fixed write support for big-endian systems

63     instrument constructors
64     - clear unused fields when saving samples and regions

80     instruments
81 persson 1218 - write support: improved the default values for dimension region
82     parameters
83 persson 1247 - more write support fixes: crossfade parameters were not saved,

88     - write support: version 3 is now the default for new files
89 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
90     dimension regions without mapped samples are now allowed, 3gnl
91     list in v3 files now always has 128 entries, several parameters
92     where incorrectly saved due to an operator precedence mistake
93     - DeleteSample now removes all references to the deleted sample
94 persson 1301 - AddDimension now copies all parameters from existing dimension
95     regions and also makes sure that the samplechannel dimension is

361 capela 168 Version 0.7.1 (2 Jul 2004)
362    
363     * packaging changes:
364 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
365     Redhat packages
366 capela 168 - header files included on installation.
367     - autotools-generated files removed from CVS repository.
368 schoenebeck 186 - added support for generating Debian packages
369     - version of shared library can be set in configure.in
370    
371 schoenebeck 58 Version 0.7.0 (3 May 2004)
372    
373     * general changes:
374     - various big endian specific corrections
375     (successfully tested now on PPC)
376     - minor adjustments to avoid compile errors on some systems
377     (using now pow() instead of powl() and --pedantic g++ compiler switch)
378     - libtoolized the library
379     - added man pages for the command line tools
380     (gigextract, gigdump, dlsdump, rifftree)
381    
382     * src/gig.cpp, src/gig.h:
383     - fixed bug in decompression algorithm which caused it not to detect
384     the end of a stream
385     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
386     takes the MIDI key velocity value as an argument and returns the
387     appropriate volume factor (0.0 ... 1.0) for the sample to be played
388     back, the velocity curve transformation functions used for this are
389     only an approximation so far
390     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
391     'Sample::LoopSize' which reflected wrong values
392     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
393     measured in sample points instead of byte offset
394     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
395     'Sample::FineTune'
396     - added class attribute 'Sample::LoopSize'
397     - added method GetInstrument(uint index) to class 'File'
398     - added ReadAndLoop() method to class 'Sample' which is an extension to
399     the normal Read() method to honor the sample's looping information
400     while streaming from disk
401     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
402     'eg2_ctrl_t': replaced this huge enumeration by a structure which
403     reflects the MIDI controller number in case of an ordinary control
404     change controller (this saves a huge switch-case block in the
405     application of the library user)
406     - renamed following attributes in class 'DimensionRegion':
407     'AttenuationContol' -> 'AttenuationController',
408     'InvertAttenuationControl' -> 'InvertAttenuationController',
409     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
410     - minor fix in API documentation for method GetVelocityAttenuation() in
411     class 'DimensionRegion'
