+  * 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).
+    - Fixed File::GetGroup(size_t) to be reentrant-safe.
+    - Marked methods GetFirstGroup() and GetNextGroup() as deprecated.
+    - Fixed GetGroup(String) to be reentrant-safe.
+    - Use GetGroup() instead of GetFirstGroup() / GetNextGroup() in entire
+      gig.cpp file.
+    - Changed signature of method File::GetInstrument(uint,progress_t*) to
+      File::GetInstrument(size_t,progress_t*).
+    - Fixed File::GetInstrument(size_t,progress_t*) to be reentrant-safe.
+    - Marked methods File::GetFirstInstrument() and File::GetNextInstrument()
+      as deprecated.
+    - Use File::GetInstrument() instead of File::GetFirstInstrument() /
+      File::GetNextInstrument() in entire gig.cpp file.
+    - Optimized method ScriptGroup::GetScript() to have constant time
+      efficiency.
+    - Changed signature of method File::GetScriptGroup(uint) to
+      File::GetScriptGroup(size_t).

   * src/SF.cpp, src/SF.h:
     - File::DeleteInstrument(): Fix clang sanatizer warning.
 
+  * src/DLS.cpp, src/DLS.h:
