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.
6        - Use libgig's new method gig::File::GetSample() with method
7          gig::File::CountSamples() instead of now deprecated
8          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.

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

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

372        - Implemented support for loading instrument scripts with 'patch' variables
373          (by patching these script variables with potentially overridden ones by
374          gig Instrument).
