3      * Real-time instrument scripts:
4        - Fix: Do not share compiled instrument scripts among multiple engine
5          channels (sampler parts) as this can lead to crashes and would allow the
6          same global script variables to be accessible from multiple engine
7          channels which would not be the expected behaviour by instrument script
8          authors.
9    
10      * GigaStudio/Gigasampler format engine:
11        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
12          issues with .gig file.
13        - Use libgig's new method gig::File::GetSample() with method
14          gig::File::CountSamples() instead of now deprecated
15          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
16        - Use libgig's new method gig::Instrument::GetRegionAt() with method
17          gig::Instrument:CountRegions() instead of now deprecated
18          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
19        - Use libgig's gig::File::GetInstrument() method with method
20          gig::File::CountInstruments() instead of now deprecated
21          gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.

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

291        the LFO frequency / resonance / cutoff frequency.        the LFO frequency / resonance / cutoff frequency.
292        - Reduced code involved for parsing NKSP variable declarations by using 2
293          generalized grammar rules with optional components (i.e. optional value
294          assignment and optional variable qualifiers) instead of previous linear
295          combinations of grammar rules, which also fixes some edge case.
296        - NKSP language parser: track code block locations also by a) raw byte
297          position in NKSP source code string and b) length of that code block in
298          bytes (along to the already existing code block tracking by line/column);
299          and added appropriate new members to public C++ API classes like
300          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
301        - NKSP language: Added support for 'patch' variable qualifier (capture their
302          locations and allow replacement of their assignment expression via VM C++
303          API).
304        - Fixed incorrect EG times if standard measuring unit was passed to built-in
305          functions "change_attack()", "change_decay()" or "change_release()".
306        - Fixed intermediate function result values never having reflected any
307          standard measuring unit type.
308        - Fixed re-entrant issue with function calls which caused wrong result
309          values if the same function was called multiple times in a term
310          (specifically if metric prefixes were used).
311        - NKSP language: Just throw a warning, not an error if an array variable of
312          size zero was declared.
313        - NKSP language: Allow omitting explicit array size on array variable
314          declaration if combined with immediate value assignment
315          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
316        - NKSP language: emit warning if an array variable was declared with bigger
317          array size than amount of initial values been assigned, and initialize the
318          missing array elements with zero in this case.
319        - Fixed built-in NKSP exit() function to behave as return statement.
320        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
321          data type.
322        - NKSP VM: Fixed the "release" handler being executed too often under
323          certain situations if polyphonic data was passed from "note" handler to
324          "release" handler.
325        - Fixed memory leak in NKSP parser: string tokens were allocated as C
326          strings and never freed.
327        - Fixed incorrect polyphonic data transfer from wrong note handler to
328          release handler; which also fixes no release handler being executed
329          sometimes, and due to the latter it also fixes potential crashes as some
330          polyphonic script events were never released and the engine hence was
331          running out of free script events.
332        - Fixed crash when handling array results of built-in functions
333          (e.g. "num_elements(by_marks($MARK_1)").
334        - NKSP VM: Fixed dead note events not been removed from user's event groups
335          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
336          and set_event_mark() after max. size of event group list was exhausted).
337

385        - Implemented support for loading instrument scripts with 'patch' variables
386          (by patching these script variables with potentially overridden ones by
387          gig Instrument).
