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.
26        - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.

80      - Fixed potential crash with high pitch at end of RAM playback.      - Fixed potential crash with high pitch at end of RAM playback.
81      - Added configure checks whether C++ compiler supports so called      - Added configure checks whether C++ compiler supports so called
82        'designated initializers'.        'designated initializers'.
83        - Added global backtraceAsString() function for debugging purposes
84          (POSIX systems only, no Windows implementation yet).
85        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
86          nameOfCaller() and setNameOfCaller().
87        - configure: Always check for availability of pthread_testcancel() and use
88          it if so (previously it was only used if explicitly enabled by configure
89          option).
90        - Thread class: raise compiler warning if pthread_testcancel() is not
91          available, because it can lead to deadlocks.
92        - Mutex class: Implemented optional bug detection and deadlock debugging
93          features.
94        - Ref<> class is now thread safe (as lock-free and wait-free
95          implementation).
96        - Fixed compilation error with Bison >= 3.6.0.
97        - Fixed rare crash when switching between instruments that had instrument
98          scripts loaded.
99        - Allow EffectChain::InsertEffect() as alternative to
100          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
101        - ConstCapacityArray class: Fixed bug in remove() method.
102        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
103          real-time instrument script was loaded.
104    
105    * Real-time instrument scripts:    * Real-time instrument scripts:

308        API).        API).
309      - Fixed incorrect EG times if standard measuring unit was passed to built-in      - Fixed incorrect EG times if standard measuring unit was passed to built-in
310        functions "change_attack()", "change_decay()" or "change_release()".        functions "change_attack()", "change_decay()" or "change_release()".
311        - Fixed intermediate function result values never having reflected any
312          standard measuring unit type.
313        - Fixed re-entrant issue with function calls which caused wrong result
314          values if the same function was called multiple times in a term
315          (specifically if metric prefixes were used).
316        - NKSP language: Just throw a warning, not an error if an array variable of
317          size zero was declared.
318        - NKSP language: Allow omitting explicit array size on array variable
319          declaration if combined with immediate value assignment
320          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
321        - NKSP language: emit warning if an array variable was declared with bigger
322          array size than amount of initial values been assigned, and initialize the
323          missing array elements with zero in this case.
324        - Fixed built-in NKSP exit() function to behave as return statement.
325        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
326          data type.
327        - NKSP VM: Fixed the "release" handler being executed too often under
328          certain situations if polyphonic data was passed from "note" handler to
329          "release" handler.
330        - Fixed memory leak in NKSP parser: string tokens were allocated as C
331          strings and never freed.
332        - Fixed incorrect polyphonic data transfer from wrong note handler to
333          release handler; which also fixes no release handler being executed
334          sometimes, and due to the latter it also fixes potential crashes as some
335          polyphonic script events were never released and the engine hence was
336          running out of free script events.
337        - Fixed crash when handling array results of built-in functions
338          (e.g. "num_elements(by_marks($MARK_1)").
339        - NKSP VM: Fixed dead note events not been removed from user's event groups
340          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
341          and set_event_mark() after max. size of event group list was exhausted).
342    
343    * test cases:    * test cases:
344      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

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