407 capela 168 Version 0.7.1 (2 Jul 2004)
408    
409     * packaging changes:
410 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
411     Redhat packages
412 capela 168 - header files included on installation.
413     - autotools-generated files removed from CVS repository.
414 schoenebeck 186 - added support for generating Debian packages
415     - version of shared library can be set in configure.in
416    
417 schoenebeck 58 Version 0.7.0 (3 May 2004)
418    
419     * general changes:
420     - various big endian specific corrections
421     (successfully tested now on PPC)
422     - minor adjustments to avoid compile errors on some systems
423     (using now pow() instead of powl() and --pedantic g++ compiler switch)
424     - libtoolized the library
425     - added man pages for the command line tools
426     (gigextract, gigdump, dlsdump, rifftree)
427    
428     * src/gig.cpp, src/gig.h:
429     - fixed bug in decompression algorithm which caused it not to detect
430     the end of a stream
431     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
432     takes the MIDI key velocity value as an argument and returns the
433     appropriate volume factor (0.0 ... 1.0) for the sample to be played
434     back, the velocity curve transformation functions used for this are
435     only an approximation so far
436     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
437     'Sample::LoopSize' which reflected wrong values
438     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
439     measured in sample points instead of byte offset
440     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
441     'Sample::FineTune'
442     - added class attribute 'Sample::LoopSize'
443     - added method GetInstrument(uint index) to class 'File'
444     - added ReadAndLoop() method to class 'Sample' which is an extension to
445     the normal Read() method to honor the sample's looping information
446     while streaming from disk
447     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
448     'eg2_ctrl_t': replaced this huge enumeration by a structure which
449     reflects the MIDI controller number in case of an ordinary control
450     change controller (this saves a huge switch-case block in the
451     application of the library user)
452     - renamed following attributes in class 'DimensionRegion':
453     'AttenuationContol' -> 'AttenuationController',
454     'InvertAttenuationControl' -> 'InvertAttenuationController',
455     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
456     - minor fix in API documentation for method GetVelocityAttenuation() in
457     class 'DimensionRegion'
458    
459     * src/RIFF.cpp, src/RIFF.h:
460     - added additional API documentation
461     - minor fix in Chunk::Read() method (only a minor efficiency issue)
462    
463     * src/gigdump.cpp:
464     - added printout of samples' looping informations
465    
466 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
467    
468     * initial release
