+
+  * general changes:
+    - Require at least a C++11 compliant compiler.
+    - Require some UUID generating function by underlying system.
+
+  * 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 methods DimensionRegion::UsesAnyGigFormatExtension(),
+      Region::UsesAnyGigFormatExtension(),
+      Instrument::UsesAnyGigFormatExtension() and
+      File::UsesAnyGigFormatExtension() (however only as private methods yet,
+      see comments on methods 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).
+    - 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,
+      LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
+      LFO2FlipPhase and LFO3FlipPhase.
