 Version SVN trunk (?)
 
+  * 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).
+
+  * 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.
+
+  * 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
+      entire RIFF.cpp file.

   * general changes:
     - Require at least a C++11 compliant compiler.
+    - Require some UUID generating function by underlying system.

       (patch by Ivan Maguidhir).
     - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
       (original patch by Ivan Maguidhir).
-    - Region::DeleteDimensionZone(): Fixed dimensions being in different order
-      after deleting a dimension zone.
+    - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
+      dimensions being in different order after deleting a dimension zone.
+    - Script: Generate a persistent UUID for each script.
+    - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
+      accordingly added new methods to Instrument class:
+      IsScriptPatchVariableSet(), GetScriptPatchVariables(),
+      GetScriptPatchVariable(), SetScriptPatchVariable(),
+      UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
+      as child of our '3LS ' list chunk on Instrument level.
+    - Fixed undefined behaviour when modifying script slots on an instrument
+      that had been cloned and not been saved yet (e.g. unintended modification
+      of original instrument's script slots, and crash on Instrument destruction
+      due to double free of pScriptRefs).
+
+  * src/Serialization.cpp, src/Serialization.h:
+    - Fixed broken Archive(RawData) constructor which always threw an
+      Exception.
+    - Added built-in support for C++ String objects (a.k.a. std::string
+      from the STL) and bumped Srx format version to 1.1 for that reason.
+    - Fixed assertion fault on some systems if a member variable defined was
+      serialized which was declared as size_t or ssize_t data type.
+    - Added new method Archive::operation() which allows applications to
+      distinguish between serialization vs. deserialization in their
+      serialize() method implementations.
+    - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
+      the STL).
+    - Member offsets are now signed and for (newly added support of) member
+      variables on the heap -1 is always used as offset instead.
+    - Added built-in support for C++ Set<> objects (a.k.a. std::set from the
+      STL).
+    - DataType: Added optional 2nd custom type name.
+    - Added built-in support for C++ Map<> objects (a.k.a. std::map from the
+      STL).
+
+  * src/helper.h:
+    - Fix compile error with GCC 9 due to ignored result value of vasprintf()
+      function call.
 
   * src/tools/gigdump.cpp:
     - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
