3    * general changes:    * general changes:
4        - AbstractEngineChannel: fixed CCs not being forwarded to all
5          VirtualMIDIDevices.
6        - Fix compiler error with release tarball if no Bison installed
7          (SVN version still requires Flex and Bison being installed).
8    
9      * Real-time instrument scripts:
10        - Fix: Do not share compiled instrument scripts among multiple engine
11          channels (sampler parts) as this can lead to crashes and would allow the
12          same global script variables to be accessible from multiple engine
13          channels which would not be the expected behaviour by instrument script
14          authors.
15    
16      * GigaStudio/Gigasampler format engine:
17        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
18          issues with .gig file.
19        - Use libgig's new method gig::File::GetSample() with method
20          gig::File::CountSamples() instead of now deprecated
21          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
22        - Use libgig's new method gig::Instrument::GetRegionAt() with method
23          gig::Instrument:CountRegions() instead of now deprecated
24          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
25        - Use libgig's gig::File::GetInstrument() method with method
26          gig::File::CountInstruments() instead of now deprecated
27          gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
28    
29      * MIDI driver:
30        - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
31          in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
32        - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
33    
34    Version 2.2.0 (9 May 2021)
35    
36      * general changes:
37      - Fixed compiler error in Pool.h.      - Fixed compiler error in Pool.h.
38      - Require C++14 compiler support.      - Require C++14 compiler support.
39      - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used      - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used

85        - Fixed playing noise at the end of a disk stream under certain conditions.
86        - Fixed potential crash with high pitch at end of RAM playback.
87        - Added configure checks whether C++ compiler supports so called
88          'designated initializers'.
89        - Added global backtraceAsString() function for debugging purposes
90          (POSIX systems only, no Windows implementation yet).
91        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
92          nameOfCaller() and setNameOfCaller().
93        - configure: Always check for availability of pthread_testcancel() and use
94          it if so (previously it was only used if explicitly enabled by configure
95          option).
96        - Thread class: raise compiler warning if pthread_testcancel() is not
97          available, because it can lead to deadlocks.
98        - Mutex class: Implemented optional bug detection and deadlock debugging
99          features.
100        - Ref<> class is now thread safe (as lock-free and wait-free
101          implementation).
102        - Fixed compilation error with Bison >= 3.6.0.
103        - Fixed rare crash when switching between instruments that had instrument
104          scripts loaded.
105        - Allow EffectChain::InsertEffect() as alternative to
106          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
107        - ConstCapacityArray class: Fixed bug in remove() method.
108        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
109          real-time instrument script was loaded.
110    
111    * Real-time instrument scripts:    * Real-time instrument scripts:

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

396        - Implemented support for loading instrument scripts with 'patch' variables
397          (by patching these script variables with potentially overridden ones by
398          gig Instrument).
