118          happened when gig::Group informations were accessed before
119        - fixed write support for big-endian systems

123          instrument constructors
124        - clear unused fields when saving samples and regions

135        - added constants for gig file versions
136        - write support: the 3crc and einf chunks are now created or
137          updated when a file is saved (3crc contains sample checksums,
138          einf contains file statistics)
139        - write support: DLSID is now generated on the file and the
140          instruments
141        - write support: improved the default values for dimension region
142          parameters

145          when dimensions were added or deleted, v3 wave pool offsets were
146          not saved correctly
147        - write support: 24 bit samples can now be written
148        - write support: version 3 is now the default for new files
149        - more write support fixes: the 3ewg chunk is now bigger for v3,
150          dimension regions without mapped samples are now allowed, 3gnl
151          list in v3 files now always has 128 entries, several parameters
152          where incorrectly saved due to an operator precedence mistake
153        - DeleteSample now removes all references to the deleted sample
154        - AddDimension now copies all parameters from existing dimension
155          regions and also makes sure that the samplechannel dimension is
156          placed first in the list of dimensions.
157        - added method GetParent() to class 'DimensionRegion', which returns its
158          parent Region
159        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
160          unused areas
161        - added various setter methods to DimensionRegion class which take care
162          of updating lookup tables / caches.
163    
164      * src/RIFF.cpp, src/RIFF.h:
165        - added File::SetByteOrder method
166        - Windows fix: saving a new file didn't work

181          velocity (gig v3 feature)
182        - added "smart midi" and "round robin keyboard" dimensions
183        - added new method File::DeleteGroupOnly() which only deletes the given
184          group but moves all its members to another group, the other method,
185          that is File::DeleteGroup() now removes not just the group, but also
186          all the samples that belong to that group
187        - fixed crash which occured on interfering File::DeleteSample() and
188          File::GetNextSample() calls (due to iterator invalidation)

194          when used from Instrument::AddRegion
195        - when saving, override the gig::Regions sample reference simply by
196          the region's first dimension region's sample (avoids an exception
197          when trying to save a new instrument)

222        - sample loop parameters are now taken from the DimensionRegion
223          instead of the wave chunk
224        - keyswitching dimension is changed from split type "normal" to
225          "bit"
226        - real support for 24 bit samples - samples are not truncated to
227          16 bits anymore
228        - support for reading of ".art" files. (Merging of .art and .gig
229          files are not implemented yet.)

259    
260      * src/gig.cpp, src/gig.h:

277          resize and write operations in one rush
278    
279      * src/gigdump.cpp:
280        - fixed to show the correct amount of dimension regions instead of 32

387    
388      * packaging changes:
389        - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
