       instrument editor.
     - Fixed playing noise at the end of a disk stream under certain conditions.
     - Fixed potential crash with high pitch at end of RAM playback.
+    - Added configure checks whether C++ compiler supports so called
+      'designated initializers'.
+    - Added global backtraceAsString() function for debugging purposes
+      (POSIX systems only, no Windows implementation yet).
+    - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
+      nameOfCaller() and setNameOfCaller().
+    - configure: Always check for availability of pthread_testcancel() and use
+      it if so (previously it was only used if explicitly enabled by configure
+      option).
+    - Thread class: raise compiler warning if pthread_testcancel() is not
+      available, because it can lead to deadlocks.
+    - Mutex class: Implemented optional bug detection and deadlock debugging
+      features.
+    - Ref<> class is now thread safe (as lock-free and wait-free
+      implementation).
+    - Fixed compilation error with Bison >= 3.6.0.
+    - Fixed rare crash when switching between instruments that had instrument
+      scripts loaded.
+    - Allow EffectChain::InsertEffect() as alternative to
+      EffectChain::AppendEffect() (i.e. with index equal to current chain size).

       and added appropriate new members to public C++ API classes like
       'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
+    - NKSP language: Added support for 'patch' variable qualifier (capture their
+      locations and allow replacement of their assignment expression via VM C++
+      API).
+    - Fixed incorrect EG times if standard measuring unit was passed to built-in
+      functions "change_attack()", "change_decay()" or "change_release()".
+    - Fixed intermediate function result values never having reflected any
+      standard measuring unit type.
+    - Fixed re-entrant issue with function calls which caused wrong result
+      values if the same function was called multiple times in a term
+      (specifically if metric prefixes were used).
+    - NKSP language: Just throw a warning, not an error if an array variable of
+      size zero was declared.
+    - NKSP language: Allow omitting explicit array size on array variable
+      declaration if combined with immediate value assignment
+      (e.g. declare %foo[] := ( 1, 2, 3 ) ).
+    - NKSP language: emit warning if an array variable was declared with bigger
+      array size than amount of initial values been assigned, and initialize the
+      missing array elements with zero in this case.
+    - Fixed built-in NKSP exit() function to behave as return statement.
+    - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
+      data type.
+    - NKSP VM: Fixed the "release" handler being executed too often under
+      certain situations if polyphonic data was passed from "note" handler to
+      "release" handler.
+    - Fixed memory leak in NKSP parser: string tokens were allocated as C
+      strings and never freed.
+    - Fixed incorrect polyphonic data transfer from wrong note handler to
+      release handler; which also fixes no release handler being executed
+      sometimes, and due to the latter it also fixes potential crashes as some
+      polyphonic script events were never released and the engine hence was
+      running out of free script events.

     - If minimum cutoff is defined, remap cutoff controller CC values to really
       span the entire possible cutoff range (and avoiding a dead controller

+    - Implemented support for loading instrument scripts with 'patch' variables
+      (by patching these script variables with potentially overridden ones by
+      gig Instrument).
 
   * SFZ format engine:
     - Fixed support for regions with loccN/hiccN conditions on more than one
       MIDI controller.
