+  * src/gig.cpp, src/gig.h:
+    - Region::DeleteDimensionZone(): Fix clang sanatizer warning.
+    - Region::SplitDimensionZone(): Fix clang sanatizer warning.
+    - Sample: Fix unnecessary RAM consumption in case of 24 bit samples
+      (InternalDecompressionBuffer is no longer needed for 24 bit samples since
+      SVN r902 / libgig release 3.1.0).
+    - Use GetSubChunkAt() instead of GetFirstSubChunk() / GetNextSubChunk() in
+      entire gig.cpp file.
+    - Use GetSubListAt() instead of GetFirstSubList() / GetNextSubList() in
+      entire gig.cpp file.
+    - Added method Instrument::GetRegionAt().
+    - Marked methods Instrument::GetFirstRegion() and
+      Instrument::GetNextRegion() as deprecated.
+    - Use GetRegionAt() instead of GetFirstRegion() / GetNextRegion() in entire
+      gig.cpp file.
+    - Changed signature of method File::GetSample(uint) to
+      File::GetSample(size_t,progress_t*).
+    - Marked methods File::GetFirstSample() and File::GetNextSample() as
+      deprecated.
+    - Use File::GetSample() instead of File::GetFirstSample() /
+      File::GetNextSample() in entire gig.cpp file.
+    - Added method Group::GetSample().
+    - Marked methods Group::GetFirstSample() and Group::GetNextSample() as
+      deprecated.
+    - Use Group::GetSample() instead of Group::GetFirstSample() /
+      Group::GetNextSample() in entire gig.cpp file.
+    - Changed signature of method File::GetGroup(uint) to
+      File::GetGroup(size_t).
+
+  * src/SF.cpp, src/SF.h:
+    - File::DeleteInstrument(): Fix clang sanatizer warning.
+
+  * src/DLS.cpp, src/DLS.h:
+    - Use GetSubChunkAt() instead of GetFirstSubChunk() / GetNextSubChunk() in
+      entire DLS.cpp file.
+    - Use GetSubListAt() instead of GetFirstSubList() / GetNextSubList() in
+      entire DLS.cpp file.
+    - Added method Instrument::GetRegionAt().
+    - Marked methods Instrument::GetFirstRegion() and
+      Instrument::GetNextRegion() as deprecated.
+    - Use GetRegionAt() instead of GetFirstRegion() / GetNextRegion() in entire
+      DLS.cpp file.
+    - Added method File::GetSample().
+    - Marked methods File::GetFirstSample() and File::GetNextSample() as
+      deprecated.

+      File::GetNextSample() in entire DLS.cpp file.
+
+  * src/RIFF.cpp, src/RIFF.h:
+    - Chunk::LoadChunkData(): Fix clang sanatizer warning.
+    - List::LoadSubChunks(): Fix potential garbage data access if reading a
+      RIFF chunk ID failed.
+    - Added methods File::IsIOPerThread() and File::SetIOPerThread(bool); the
+      latter allows to automatically use a separate file I/O stream state for
+      each thread.
+    - Added method List::GetSubChunkAt().
+    - Added method List::GetSubListAt().
+    - Marked methods List::GetFirstSubChunk(), List::GetNextSubChunk(),
+      List::GetFirstSubList() and List::GetNextSubList() as deprecated.
+    - Use GetSubListAt() instead of GetFirstSubList() / GetNextSubList() in
