     - RTMath: Implemented floating point comparison methods
       fEqual32(float,float) and fEqual64(double,double) which take the
       expected floating point tolerances into account.
+    - Added public API C++ class "LFO", which is a cluster class encapsulating
+      all the sampler's LFO implementations to be used by 3rd party applications
+      (e.g. by Gigedit).
+    - Added int math square LFO implementation.
+    - Added int math saw LFO implementation.
+    - Added numeric complex nr sine LFO implementation.
+    - Marked class LFOTriangleDiHarmonic as deprecated
+      (will be removed in future).
+    - Added LFOAll.h which includes all LFO implementation's header files.
+    - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
+      LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
+      SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
+      SquareLFO -> LFOSquarePulse and separated the latter to its own header
+      file).
+    - Renamed type LFOSigned -> LFOTriangleSigned.
+    - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
+    - Using now cubic interpolation as resampling algorithm by default; and
+      linear interpolation is deprecated now.

+  * GigaStudio/Gigasampler format engine:
+    - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
+      behaviour for start_level_mid.
+    - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
+      level (see discussion "GigaStudio LFO compatibility" on mailing list
+      from 2019-09-26 for details).
+    - Changed default wave form for all 3 LFOs to sine (instead of triangle;
+      see discussion "GigaStudio LFO compatibility" on mailing list from
+      2019-09-26 for details).
+    - Format extension: Added support for different LFO wave forms (currently
+      either sine [default], triangle, saw or square).
+    - Format extension: Added support for LFO phase displacement (0°..360°).
+    - Format extension: Added support for flipping LFO polarity on LFO 3
+      (in the original gig format this was only available for LFO 1 and LFO 2).
+
+  * SFZ format engine:
+    - Fixed support for regions with loccN/hiccN conditions on more than one
+      MIDI controller.
+
+  * Benchmarks:
+    - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
+      algorithm (since result of 2nd run was not accumulated).
+    - Added benchmark for saw wave (benchmarks/saw.cpp).
+    - Added benchmark for sine wave (benchmarks/sine.cpp).
+    - Added benchmark for square wave (benchmarks/square.cpp).
+    - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
+      which are large enough on modern systems.
