 Version SVN trunk (?)
 
   * general changes:
+    - Require at least a C++11 compliant compiler.
+
+  * src/gig.cpp, src/gig.h:
+    - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
+      DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
+      allow to define override LFOs' wave form (e.g. saw or square instead of
+      the default wave form which was always sine in the original
+      Gigasampler/GigaStudio software).
+    - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
+      DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
+      move the start point horizontally of the LFOs' waves (0° ... 360°).
+    - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
+      (the original Gigasampler/GigaStudio software only had that flip phase
+      option for LFO1 and LFO2).
+    - Added method DimensionRegion::UsesAnyGigFormatExtension() (however only as
+      private method yet, see comments on method why).
+    - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
+      implementations to enum vcf_type_t: vcf_type_lowpass_1p,
+      vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
+      vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
+      vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
+    - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
+      (patch by Ivan Maguidhir).
+    - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
+      (original patch by Ivan Maguidhir).
+
+  * src/tools/gigdump.cpp:
+    - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
+      LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
+      LFO2FlipPhase and LFO3FlipPhase.

+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: 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
