   * general changes:
     - Fixed compiler error in Pool.h.
     - Require C++14 compiler support.
+    - Require C11 compliant compiler.
     - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
       for checking in configure for C++14 support (as mandatory
       requirement) and automatically adds compiler argument if required

     - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
       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).

+    - Reduced code involved for parsing NKSP variable declarations by using 2
+      generalized grammar rules with optional components (i.e. optional value
+      assignment and optional variable qualifiers) instead of previous linear
+      combinations of grammar rules, which also fixes some edge case.
+    - NKSP language parser: track code block locations also by a) raw byte
+      position in NKSP source code string and b) length of that code block in
+      bytes (along to the already existing code block tracking by line/column);
+      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
