     - Renamed type LFOSigned -> LFOTriangleSigned.
     - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
+    - Using now cubic interpolation as resampling algorithm by default; and
+      linear interpolation is deprecated now.
+    - Event:Init(): memset() entire Event::Param union to zero instead of trying
+      to do that for its individual members; the latter became error prone due
+      to the union's growing complexity meanwhile.
+    - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
+      *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
+      methods and marked the old ones as deprecated; and likewise added new
+      *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
+      methods and marked those old ones deprecated as well.
+    - Added support for MIDI CC #38 (data entry LSB): this allows higher value
+      resolution for certain (e.g. hard coded) RPN and NRPN parameters.
+    - Implemented support for compressed RPN/NRPN message sequences (that is to
+      allow processing MIDI data entry messages without always having to be
+      preceded strictly by RPN/NRPN parameter selection messages on each value
+      change).
+    - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
+      decrement).
+    - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
+      MSB=127 and LSB=127) and which is disabling subsequent data
+      entry/increment/decrement CC messages.

     - NKSP language: Allow unary '+' operator.

+    - NKSP language: Added support for RPN event handler
+      ("on rpn ... end on" in instrument scripts).
+    - NKSP language: Added support for NRPN event handler
+      ("on nrpn ... end on" in instrument scripts).
+    - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
+      may be read from the new RPN/NRPN script handlers to get the (N)RPN
+      parameter that had been changed and its new value.
+    - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
+      which are identifying the new (N)RPN handlers as such at script runtime.
+    - Implemented built-in script function "set_rpn()".
+    - Implemented built-in script function "set_nrpn()".
+    - Fix: built-in functions returning an array type were broken and caused a
+      crash when the built-in function's (supposed to be array) result value was
+      used by the script VM.

     - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start

+    - 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
