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

140        - write support: the 3crc and einf chunks are now created or
141          updated when a file is saved (3crc contains sample checksums,
142          einf contains file statistics)
143        - write support: DLSID is now generated on the file and the
144          instruments
145        - write support: improved the default values for dimension region
146          parameters

150          not saved correctly
151        - write support: 24 bit samples can now be written
152        - write support: version 3 is now the default for new files

157        - DeleteSample now removes all references to the deleted sample
158        - AddDimension now copies all parameters from existing dimension
159          regions and also makes sure that the samplechannel dimension is
160          placed first in the list of dimensions.
161        - added method GetParent() to class 'DimensionRegion', which returns its
162          parent Region
163        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
164          unused areas
165        - added various setter methods to DimensionRegion class which take care
166          of updating lookup tables / caches.
167    
168      * src/RIFF.cpp, src/RIFF.h:
169        - added File::SetByteOrder method
170        - Windows fix: saving a new file didn't work

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

198          when used from Instrument::AddRegion

200          the region's first dimension region's sample (avoids an exception

227          instead of the wave chunk
228        - keyswitching dimension is changed from split type "normal" to
229          "bit"
230        - real support for 24 bit samples - samples are not truncated to

281          resize and write operations in one rush
282    
283      * src/gigdump.cpp:
