+Version 4.2.0 (25 Jul 2019)
+
+  * general changes:
+    - Added MSVC build support (anonymous patch from mailing list).
+    - Introduced CMake build support (yet constrained for building with MSVC)
+      (anonymous patch from mailing list).
+    - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
+      destructors. Added new virtual method DeleteChunks() to those classes
+      for this which must be explicitly called instead to remove their RIFF
+      chunks.
+    - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
+      of zero; which is unsafe per se.
+    - Added C++11 "override" keyword where appropriate.
+    - Fixed crash in RIFF, DLS and gig classes which occurred on certain
+      of their actions when not passing a progress_t callback structure.
 
   * src/gig.cpp, src/gig.h:
     - Fixed Doxygen API comments for enum types (currently latest Doxygen

       not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
       the Doxygen source code, which currently also filter out new line

+    - Added new method File::CountSamples().
+    - Added new method File::CountInstruments().
+    - Fixed gig v4 files falsely being handled as v2 format
+      (patch by Ivan Maguidhir).
+    - Added gig v4 version identifier (File::VERSION_4).
+    - GIG FORMAT EXTENSION: Added attribute
+      DimensionRegion::SustainReleaseTrigger which allows to define whether
+      a sustain pedal up event shall cause a release trigger sample to be
+      played (default: don't play release trigger sample by sustain pedal).
+    - GIG FORMAT EXTENSION: Added attribute
+      DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
+      regular behaviour of playing release trigger sample on MIDI note-off
+      events.
+    - Introduced support for writing extension files (.gx01, .gx02, ...)
+      (original patch by Ivan Maguidhir).
+    - Many gig classes derive now from DLS::Storage (see DLS changes below).
+    - Added File::GetRiffFile() method.
+
+  * src/DLS.cpp, src/DLS.h:
+    - File: Fixed implicitly allocated RIFF::File object never been freed.
+    - Added new abstract interface base class DLS::Storage which is derived by
+      the respective classes for implementing (the old) UpdateChunks() and the
+      new DeleteChunks() method.
+    - Added File::GetRiffFile() method.
+
+  * src/sf2.cpp, src/sf2.h:
+    - Added Sample::GetFile() method.
+    - Added File::GetRiffFile() method.
 
   * src/Serialization.cpp, src/Serialization.h:
     - Hide pure internal declarations from header file to avoid numerous
       compiler warnings when building and linking against the public API.
+    - Fixed comparision logic bug
+    - Fixed memory leak in DataType::customTypeName().
+
+  * src/RIFF.cpp, src/RIFF.h:
+    - Fix: Calling File::SetMode() left an undefined file handle on Windows and
+      caused a resource leak
+    - Avoid compiler warning when building for 32 bit windows.
+    - Added new method progress_t::subdivide().
+    - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
+    - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
+      allows a more fine graded control into which portions the subtasks are
+      divided to.
+
+  * src/tools/gigdump.cpp:
+    - Added command line option --instrument-names which causes only
+      instrument names and their index numbers to be printed.
