3      * GigaStudio/Gigasampler format engine:
4        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
5          issues with .gig file.

58      - 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.
59      - Fixed potential crash with high pitch at end of RAM playback.      - Fixed potential crash with high pitch at end of RAM playback.
60        - Added configure checks whether C++ compiler supports so called
61          'designated initializers'.
62        - Added global backtraceAsString() function for debugging purposes
63          (POSIX systems only, no Windows implementation yet).
64        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
65          nameOfCaller() and setNameOfCaller().
66        - configure: Always check for availability of pthread_testcancel() and use
67          it if so (previously it was only used if explicitly enabled by configure
68          option).
69        - Thread class: raise compiler warning if pthread_testcancel() is not
70          available, because it can lead to deadlocks.
71        - Mutex class: Implemented optional bug detection and deadlock debugging
72          features.
73        - Ref<> class is now thread safe (as lock-free and wait-free
74          implementation).
75        - Fixed compilation error with Bison >= 3.6.0.
76        - Fixed rare crash when switching between instruments that had instrument
77          scripts loaded.
78        - Allow EffectChain::InsertEffect() as alternative to
79          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
80        - ConstCapacityArray class: Fixed bug in remove() method.
81        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
82          real-time instrument script was loaded.

277        generalized grammar rules with optional components (i.e. optional value        generalized grammar rules with optional components (i.e. optional value
278        assignment and optional variable qualifiers) instead of previous linear        assignment and optional variable qualifiers) instead of previous linear
279        combinations of grammar rules, which also fixes some edge case.        combinations of grammar rules, which also fixes some edge case.
280        - NKSP language parser: track code block locations also by a) raw byte
281          position in NKSP source code string and b) length of that code block in
282          bytes (along to the already existing code block tracking by line/column);
283          and added appropriate new members to public C++ API classes like
284          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
285        - NKSP language: Added support for 'patch' variable qualifier (capture their
286          locations and allow replacement of their assignment expression via VM C++
287          API).
288        - Fixed incorrect EG times if standard measuring unit was passed to built-in
289          functions "change_attack()", "change_decay()" or "change_release()".
290        - Fixed intermediate function result values never having reflected any
291          standard measuring unit type.
292        - Fixed re-entrant issue with function calls which caused wrong result
293          values if the same function was called multiple times in a term
294          (specifically if metric prefixes were used).
295        - NKSP language: Just throw a warning, not an error if an array variable of
296          size zero was declared.
297        - NKSP language: Allow omitting explicit array size on array variable
298          declaration if combined with immediate value assignment
299          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
300        - NKSP language: emit warning if an array variable was declared with bigger
301          array size than amount of initial values been assigned, and initialize the
302          missing array elements with zero in this case.
303        - Fixed built-in NKSP exit() function to behave as return statement.
304        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
305          data type.
306        - NKSP VM: Fixed the "release" handler being executed too often under
307          certain situations if polyphonic data was passed from "note" handler to
308          "release" handler.
309        - Fixed memory leak in NKSP parser: string tokens were allocated as C
310          strings and never freed.
311        - Fixed incorrect polyphonic data transfer from wrong note handler to
312          release handler; which also fixes no release handler being executed
313          sometimes, and due to the latter it also fixes potential crashes as some
314          polyphonic script events were never released and the engine hence was
315          running out of free script events.
316        - Fixed crash when handling array results of built-in functions
317          (e.g. "num_elements(by_marks($MARK_1)").
318        - NKSP VM: Fixed dead note events not been removed from user's event groups
319          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
320          and set_event_mark() after max. size of event group list was exhausted).
321    
322    * test cases:    * test cases:
323      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

369        - Implemented support for loading instrument scripts with 'patch' variables
370          (by patching these script variables with potentially overridden ones by
371          gig Instrument).

376        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
377          'xfin_lovel' (patch by Christian Czezatke).
