408     - autotools-generated files removed from CVS repository.
409 schoenebeck 186 - added support for generating Debian packages
410     - version of shared library can be set in configure.in
411    
412 schoenebeck 58 Version 0.7.0 (3 May 2004)
413    
414     * general changes:
415     - various big endian specific corrections
416     (successfully tested now on PPC)
417     - minor adjustments to avoid compile errors on some systems
418     (using now pow() instead of powl() and --pedantic g++ compiler switch)
419     - libtoolized the library
420     - added man pages for the command line tools
421     (gigextract, gigdump, dlsdump, rifftree)
422    
423     * src/gig.cpp, src/gig.h:
424     - fixed bug in decompression algorithm which caused it not to detect
425     the end of a stream
426     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
427     takes the MIDI key velocity value as an argument and returns the
428     appropriate volume factor (0.0 ... 1.0) for the sample to be played
429     back, the velocity curve transformation functions used for this are
430     only an approximation so far
431     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
432     'Sample::LoopSize' which reflected wrong values
433     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
434     measured in sample points instead of byte offset
435     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
436     'Sample::FineTune'
437     - added class attribute 'Sample::LoopSize'
438     - added method GetInstrument(uint index) to class 'File'
439     - added ReadAndLoop() method to class 'Sample' which is an extension to
440     the normal Read() method to honor the sample's looping information
441     while streaming from disk
442     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
443     'eg2_ctrl_t': replaced this huge enumeration by a structure which
444     reflects the MIDI controller number in case of an ordinary control
445     change controller (this saves a huge switch-case block in the
446     application of the library user)
447     - renamed following attributes in class 'DimensionRegion':
448     'AttenuationContol' -> 'AttenuationController',
449     'InvertAttenuationControl' -> 'InvertAttenuationController',
450     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
451     - minor fix in API documentation for method GetVelocityAttenuation() in
452     class 'DimensionRegion'
453    
454     * src/RIFF.cpp, src/RIFF.h:
455     - added additional API documentation
456     - minor fix in Chunk::Read() method (only a minor efficiency issue)
457    
458     * src/gigdump.cpp:
459     - added printout of samples' looping informations
460    
461 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
462    
463     * initial release
