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.
22    
23      * MIDI driver:
24        - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
25          in "panic" / MIDI "all sound off" / MIDI "all note off" situations.

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

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

389        - Implemented support for loading instrument scripts with 'patch' variables
390          (by patching these script variables with potentially overridden ones by
