52      - Fixed playing noise at the end of a disk stream under certain conditions.      - Fixed playing noise at the end of a disk stream under certain conditions.
53        - Fixed potential crash with high pitch at end of RAM playback.
54        - Added configure checks whether C++ compiler supports so called
55          'designated initializers'.
56        - Added global backtraceAsString() function for debugging purposes
57          (POSIX systems only, no Windows implementation yet).
58        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
59          nameOfCaller() and setNameOfCaller().
60        - configure: Always check for availability of pthread_testcancel() and use
61          it if so (previously it was only used if explicitly enabled by configure
62          option).
63        - Thread class: raise compiler warning if pthread_testcancel() is not
64          available, because it can lead to deadlocks.
65        - Mutex class: Implemented optional bug detection and deadlock debugging
66          features.
67        - Ref<> class is now thread safe (as lock-free and wait-free
68          implementation).
69        - Fixed compilation error with Bison >= 3.6.0.
70        - Fixed rare crash when switching between instruments that had instrument
71          scripts loaded.
72        - Allow EffectChain::InsertEffect() as alternative to
73          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
74

266        the LFO frequency / resonance / cutoff frequency.        the LFO frequency / resonance / cutoff frequency.
267        - Reduced code involved for parsing NKSP variable declarations by using 2
268          generalized grammar rules with optional components (i.e. optional value
269          assignment and optional variable qualifiers) instead of previous linear
270          combinations of grammar rules, which also fixes some edge case.
271        - NKSP language parser: track code block locations also by a) raw byte
272          position in NKSP source code string and b) length of that code block in
273          bytes (along to the already existing code block tracking by line/column);
274          and added appropriate new members to public C++ API classes like
275          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
276        - NKSP language: Added support for 'patch' variable qualifier (capture their
277          locations and allow replacement of their assignment expression via VM C++
278          API).
279        - Fixed incorrect EG times if standard measuring unit was passed to built-in
280          functions "change_attack()", "change_decay()" or "change_release()".
281        - Fixed intermediate function result values never having reflected any
282          standard measuring unit type.
283        - Fixed re-entrant issue with function calls which caused wrong result
284          values if the same function was called multiple times in a term
285          (specifically if metric prefixes were used).
286        - NKSP language: Just throw a warning, not an error if an array variable of
287          size zero was declared.
288        - NKSP language: Allow omitting explicit array size on array variable
289          declaration if combined with immediate value assignment
290          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
291        - NKSP language: emit warning if an array variable was declared with bigger
292          array size than amount of initial values been assigned, and initialize the
293          missing array elements with zero in this case.
294        - Fixed built-in NKSP exit() function to behave as return statement.
295        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
296          data type.
297        - NKSP VM: Fixed the "release" handler being executed too often under
298          certain situations if polyphonic data was passed from "note" handler to
299          "release" handler.
300        - Fixed memory leak in NKSP parser: string tokens were allocated as C
301          strings and never freed.
302        - Fixed incorrect polyphonic data transfer from wrong note handler to
303          release handler; which also fixes no release handler being executed
304          sometimes, and due to the latter it also fixes potential crashes as some
305          polyphonic script events were never released and the engine hence was
306          running out of free script events.
307

355        - Implemented support for loading instrument scripts with 'patch' variables
