27        file).        file).
28      - Renamed type LFOSigned -> LFOTriangleSigned.      - Renamed type LFOSigned -> LFOTriangleSigned.
29      - Renamed type LFOUnsigned -> LFOTriangleUnsigned.      - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
30        - Using now cubic interpolation as resampling algorithm by default; and
31          linear interpolation is deprecated now.
32        - Event:Init(): memset() entire Event::Param union to zero instead of trying
33          to do that for its individual members; the latter became error prone due
34          to the union's growing complexity meanwhile.
35        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
36          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
37          methods and marked the old ones as deprecated; and likewise added new
38          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
39          methods and marked those old ones deprecated as well.
40        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
41          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
42        - Implemented support for compressed RPN/NRPN message sequences (that is to
43          allow processing MIDI data entry messages without always having to be
44          preceded strictly by RPN/NRPN parameter selection messages on each value
45          change).
46        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
47          decrement).
48        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
49          MSB=127 and LSB=127) and which is disabling subsequent data
50          entry/increment/decrement CC messages.
51        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
52          instrument editor.
53        - Fixed playing noise at the end of a disk stream under certain conditions.
54        - Fixed potential crash with high pitch at end of RAM playback.
55        - Added configure checks whether C++ compiler supports so called
56          'designated initializers'.
57        - Added global backtraceAsString() function for debugging purposes
58          (POSIX systems only, no Windows implementation yet).
59        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
60          nameOfCaller() and setNameOfCaller().
61        - configure: Always check for availability of pthread_testcancel() and use
62          it if so (previously it was only used if explicitly enabled by configure
63          option).
64        - Thread class: raise compiler warning if pthread_testcancel() is not
65          available, because it can lead to deadlocks.
66        - Mutex class: Implemented optional bug detection and deadlock debugging
67          features.
68        - Ref<> class is now thread safe (as lock-free and wait-free
69          implementation).

239      - Added built-in script real number constant "~NI_MATH_PI".      - Added built-in script real number constant "~NI_MATH_PI".
240      - Added built-in script real number constant "~NI_MATH_E".      - Added built-in script real number constant "~NI_MATH_E".
241      - NKSP language: Allow unary '+' operator.      - NKSP language: Allow unary '+' operator.
242        - Added built-in script functions "msb()" and "lsb()".
243        - NKSP language: Added support for RPN event handler
244          ("on rpn ... end on" in instrument scripts).
245        - NKSP language: Added support for NRPN event handler
246          ("on nrpn ... end on" in instrument scripts).
247        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
248          may be read from the new RPN/NRPN script handlers to get the (N)RPN
249          parameter that had been changed and its new value.
250        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
251          which are identifying the new (N)RPN handlers as such at script runtime.
252        - Implemented built-in script function "set_rpn()".
253        - Implemented built-in script function "set_nrpn()".
254        - Fix: built-in functions returning an array type were broken and caused a
255          crash when the built-in function's (supposed to be array) result value was
256          used by the script VM.
257        - Removed upper value constraint for 2nd argument of built-in functions
258          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
259          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
260          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
261          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
262          the LFO frequency / resonance / cutoff frequency.
263        - Reduced code involved for parsing NKSP variable declarations by using 2
264          generalized grammar rules with optional components (i.e. optional value
265          assignment and optional variable qualifiers) instead of previous linear
266          combinations of grammar rules, which also fixes some edge case.
267        - NKSP language parser: track code block locations also by a) raw byte
268          position in NKSP source code string and b) length of that code block in
269          bytes (along to the already existing code block tracking by line/column);
270          and added appropriate new members to public C++ API classes like
271          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
272        - NKSP language: Added support for 'patch' variable qualifier (capture their
273          locations and allow replacement of their assignment expression via VM C++
274          API).
275        - Fixed incorrect EG times if standard measuring unit was passed to built-in
276          functions "change_attack()", "change_decay()" or "change_release()".
277        - Fixed intermediate function result values never having reflected any
278          standard measuring unit type.
279        - Fixed re-entrant issue with function calls which caused wrong result
280          values if the same function was called multiple times in a term
281          (specifically if metric prefixes were used).
282    
283    * test cases:    * test cases:
284      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

303        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
304        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
305      - Added NKSP test cases for unary '+' operator.      - Added NKSP test cases for unary '+' operator.
306        - Added NKSP test cases for core built-in variables.
307        - Added thorough NKSP test cases for variable declarations.
308

320      - Format extension: Added support for LFO phase displacement (0°..360°).      - Format extension: Added support for LFO phase displacement (0°..360°).
321      - Format extension: Added support for flipping LFO polarity on LFO 3      - Format extension: Added support for flipping LFO polarity on LFO 3
322        (in the original gig format this was only available for LFO 1 and LFO 2).        (in the original gig format this was only available for LFO 1 and LFO 2).
323        - Format extension: Support for additional filter types:
324          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
325          bandreject 2-pole.
326        - Fixd potential crash with polynomial interpolator and max. pitch.
327        - If minimum cutoff is defined, remap cutoff controller CC values to really
328          span the entire possible cutoff range (and avoiding a dead controller
329          zone).
330        - Implemented support for loading instrument scripts with 'patch' variables
331          (by patching these script variables with potentially overridden ones by
332          gig Instrument).
333
