- Version CVS HEAD (?)
+ Version SVN trunk
+   * general changes:
+     - removed 2 GB limitation when loading a gig or DLS file
+     - using now native integer size where appropriate
+   * src/gig.cpp, src/gig.h:
+     - fixed bug in Script::SetGroup: the script chunk wasn't moved
+     - fixed compilation error with clang 3.4
+     - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
+       as one single monolithic gig file. In case .gig file is >= 2GB expect a
+       large monolithic file, otherwise if .gig file is < 2 GB check for
+       "extension" files (.gx01, .gx02, ...) instead.
+   * src/DLS.cpp, src/DLS.h:
+     - Sample: wave pool offsets are now 64 bits (to allow support for files
+       larger than 4 GB).
+   * src/RIFF.cpp, src/RIFF.h:
+     - added support for RIFF files larger than 4 GB, by default the required
+       internal RIFF file offset size is automatically detected (that is RIFF
+       files < 4 GB automatically use 32 bit offsets while files >= 4 GB
+       automatically use 64 bit offsets), a particular offset size can be forced
+       with a new option added to the RIFF File constructor though
+     - when saving a modified, grown RIFF file, the temporary file size during
+       Save() operation will no longer be larger than the final grown file size
+   * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
+     - improved output of non-ascii characters in usage messages
+     - fixed printf format strings
+   * src/tools/korg2gig.cpp:
+     - fixed c++11 narrowing warnings
+     - fixed fine tuning which was not translated at all
+   * packaging changes:
+     - Automake: set environment variable GCC_COLORS=auto to allow GCC to
+       auto detect whether it (sh/c)ould output its messages in color.
+ Version 4.0.0 (14 Jul 2015)
+   * general changes:
+     - minor Makefile fix for parallel make
+     - Mac OS X: link with CoreFoundation (for the UUID function)
+     - removed gcc 4.7 warnings
+     - modernized configure script
+     - removed usage of deprecated Automake variable INCLUDES
+     - added new command line tool "gigmerge"
+     - added "const" keyword to several methods
+     - added new command line tool "gig2mono"
+     - added man page for "sf2dump"
+     - added new command line tool "korgdump" (and a man page for it)
+     - added new command line tool "korg2gig" (and a man page for it)
+     - moved source files of command line tools to new subdir src/tools
+     - libgig.so and libakai.so files are now installed under
+       $(prefix)/lib/libgig/ by default.
+     - Header files are now installed under $(prefix)/include/libgig/ by default.
+     - Fixed various packaging issues regarding installation directories
+       (fixes #218).
+     - added new command line tool "gig2stereo" (and a man page for it)
+     - unit tests: fixed wrong return value when test suite app exits
+       (patch by Ryan Schmidt)
+     - added new command line tool "sf2extract" (and a man page for it)
+   * SoundFont file format:
+     - initial implementation
+     - changed region lookup API to avoid malloc in RT threads
+     - fixed GetEG1Sustain which didn't return correct value
+     - bugfix: GetPan always returned -1, 0 or 1
+   * KORG file format:
+     - initial support for sample based instruments in KORG's file format
+       (.KMP and .KSF files)
+   * AKAI file format:
+     - Added Linux/POSIX ported version of libakai. Note that libakai is released
+       under LGPL terms while libgig is released under GPL terms. To handle this
+       license difference appropriately the AKAI support part is built as
+       separate DLL (.so file).
+     - Fixed Mac OSX support so that the Akai lib files and tools compile without
+       any exotic third party libraries.
+     - Fixed various compilation errors for Windows.
+     - POSIX fix: open() requires third (mode) argument if used with O_CREAT
+       (fixes #219).
+   * src/gig.cpp:
+     - bugfix: VCF velocity dynamic range and VCF velocity curve
+       weren't saved correctly

+       rules
+     - bugfix: sample groups were sometimes created multiple times or with
+       wrong textual group name
+     - added new method File::AddContentOf() for merging .gig files
+     - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
+       controller types (only works with LinuxSampler & gigedit, will not
+       work with Gigasampler/GigaStudio)
+     - added new method File::GetGroup(String name) for getting group by name
+     - added new method Region::GetDimensionDefinition(dimension_t type)
+     - bugfix: don't alter region pointer in DimensionRegion::CopyAssign()
+     - added some more sanity checks in Region::AddDimension()
+     - added new method Region::DeleteDimensionZone(dimension_t, int)
+     - added new method Region::SplitDimensionZone(dimension_t, int)
+     - Fixed crash caused by Region::GetDimensionRegionByValue() that happened
+       with certain velocity split sounds under certain conditions (added bound
+       constraints to prevent that)
+     - GIG FORMAT EXTENSION: added support for real-time instrument scripts.
+     - added new method Region::GetDimensionRegionIndexByValue()
+     - added new method Script::GetGroup()
+     - added new method Region::SetDimensionType()
+     - Added support for custom progress notification while saving to gig file.
+     - Bugfix: Adding a new region in between two existing regions caused the
+       new one being dropped after save operation and the gig file being tainted
+       (chunks at wrong location in the RIFF tree).
+     - Added new method Instrument::MoveTo() which allows to rearrange the order
+       of instruments within the same gig file.

+       later on without passing a file name
+     - added inline helper methods overlaps() for struct range_t
+     - Added support for custom progress notification while saving to DLS file.
+     - Bugfix: Adding a new region in between two existing regions caused the
+       new one being dropped after save operation and the gig file being tainted
+       (chunks at wrong location in the RIFF tree).
+   * src/SF.cpp, src/SF.h:
+     - added new method Sample::ReadNoClear()
+   * src/RIFF.cpp, src/RIFF.h:
+     - bugfix: avoid calling read() with count 0 when writing a file,

+       than "real" RIFF files (used for KORG format support)
+     - added new method Chunk::GetFile()
+     - added new method Chunk::GetLayout()
+     - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
+       allows to move a subchunk within the current List, whereas the new 2nd
+       one allows to move the subchunk from the current list to another list
+     - POSIX: only assume -1 result value as error on open() calls
+     - POSIX: show operating system's error reason if opening a file failed
+     - Added support for custom progress notification while saving to RIFF file.

+     - Cleanup of an old DLL binary backward compatibility hack.
+   * src/gigextract.cpp:
+     - export sample loop, unity note and fine tune with libsndfile
+   * src/riftree.cpp:

+     - bugfix: removed another iterator invalidation in DeleteSample
+     - bugfix in Sample::LoadSampleData*(): reset sample read position to
+       sample start before trying to (re)load sample data from file (#82)
+     - bugfix: EG3 depth parameter was not saved correctly
+     - fixed crash which occured when streaming a gig sample with
+       bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
+   * src/RIFF.cpp, src/RIFF.h:
+     - bugfix: saving to the same file after the file size had been
+       increased made the file corrupt (#82)
+     - bugfix: refuse Chunk::Read() in case chunk has just been added, that
+       is not written physically yet (#82)

+       decreased sometimes also made the file corrupt!
+     - bugfix: undefined behavior (e.g. endless loop) when opening zero
+       length files, now throws a RIFF::Exception instead (fixes bug #121)
+     - bugfix: destructor for base class RIFF::Chunk accessed members
+       of derived class RIFF::File, which is bad, and caused crashes
+       when using Visual C++
+     - bugfix: files that contain zero length RIFF lists were not read
+       correctly (fixes #127) (bug was introduced 2009-03-13)

+     - write support: DLSID is now generated on the file and the
+       instruments
+     - write support: improved the default values for dimension region
+       parameters
+     - more write support fixes: crossfade parameters were not saved,
+       v3 dimension limits were not correctly initialized and saved
+       when dimensions were added or deleted, v3 wave pool offsets were
+       not saved correctly
+     - write support: 24 bit samples can now be written

+       where incorrectly saved due to an operator precedence mistake
+     - DeleteSample now removes all references to the deleted sample
+     - AddDimension now copies all parameters from existing dimension
+       regions and also makes sure that the samplechannel dimension is
+       placed first in the list of dimensions.
+     - added method GetParent() to class 'DimensionRegion', which returns its
+       parent Region
+     - fixed Instrument::UpdateRegionKeyTable() method which did not reset
+       unused areas
+     - added various setter methods to DimensionRegion class which take care
+       of updating lookup tables / caches.

+     - custom velocity splits now works for gig v3 files too
+     - added support for custom splits points for other dimensions than
+       velocity (gig v3 feature)
+     - added "smart midi" and "round robin keyboard" dimensions
+     - added new method File::DeleteGroupOnly() which only deletes the given
+       group but moves all its members to another group, the other method,
+       that is File::DeleteGroup() now removes not just the group, but also
+       all the samples that belong to that group

+       when used from Instrument::AddRegion
+     - when saving, override the gig::Regions sample reference simply by
+       the region's first dimension region's sample (avoids an exception
+       when trying to save a new instrument)
+     - fixed AddDimension() method which did not fill out all mandatory
+       dimension definition fields

+       of Gigasampler write support)
+ Version 3.0.0 (28 Apr 2006)
+   * general changes:
+     - added write support (that is for creating and modifying RIFF, DLS and
