10      - RTMath: Implemented floating point comparison methods      - RTMath: Implemented floating point comparison methods
11        fEqual32(float,float) and fEqual64(double,double) which take the        fEqual32(float,float) and fEqual64(double,double) which take the
12        expected floating point tolerances into account.        expected floating point tolerances into account.
13        - Added public API C++ class "LFO", which is a cluster class encapsulating
14          all the sampler's LFO implementations to be used by 3rd party applications
15          (e.g. by Gigedit).
16        - Added int math square LFO implementation.
17        - Added int math saw LFO implementation.
18        - Added numeric complex nr sine LFO implementation.
19        - Marked class LFOTriangleDiHarmonic as deprecated
20          (will be removed in future).
21        - Added LFOAll.h which includes all LFO implementation's header files.
22        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25          SquareLFO -> LFOSquarePulse and separated the latter to its own header
26          file).

136      - Added individual parse time checks of arguments to be passed to built-in      - Added individual parse time checks of arguments to be passed to built-in
137        functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",        functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
138        "array_equal()" and "search()" specific for their individual purposes.        "array_equal()" and "search()" specific for their individual purposes.
139        - NKSP VM refactoring: Renamed all methods, functions and classes matching
140          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
141          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
142          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
143          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
144          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
145          isScalarNumber() -> isNumber()).
146        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
147          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
148          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
149          as convenient methods for automatically converting values to expected
150          metric value basis.
151        - Built-in function "wait()" accepts now both integers and real numbers as
152          argument.
153        - NKSP VM API cleanup: Get rid of legacy method
154          VMFunction::argType(vmint iArg) which was already superseded by its new
155          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
156        - NKSP parser: if wrong argument type was passed to a built-in function and
157          that built-in function accepts more than one data type for the argument,
158          then show all supported data types as parser error message.
159        - Built-in function "play_note()" accepts now real numbers and seconds as
160          unit type as well for its 3rd and 4th function arguments.
161        - The following built-in functions accept now real numbers as well for their
162          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
163          "change_attack()", "change_decay()", "change_release()",
164          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
165          "change_cutoff_sustain()", "change_cutoff_release()",
166          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
167          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
168          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
169        - Fixed built-in function "change_play_pos()" not having accepted metric
170          prefixes at all.
171        - Fixed the following built-in functions having misinterpreted values given
172          with unit type (for their 2nd argument) as if they were relative values
173          (that is as if they were passed without a unit type): "change_attack()",
174          "change_decay()", "change_release()", "change_cutoff_attack()",
175          "change_cutoff_decay()", "change_cutoff_release()".
176        - Fixed the following built-in functions having applied completely wrong
177          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
178          respective EGs being their modulation sink assume uint data type with
179          value range 0..1000 instead of 0.0..1.0.
180        - Added individual parse-time checks of function arguments for the following
181          built-in functions: "play_note()", "note_off()", "set_event_mark()",
182          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
183          "change_decay()", "change_release()", "change_cutoff_attack()",
184          "change_cutoff_decay()", "change_cutoff_release()",
185          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
186          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
187          "change_pan_time()".
188        - Don't abort function call if unit type was used and at the same time
189          'final' operator was omitted for the primary value argument of the
190          following built-in functions: "change_cutoff()", "change_attack()",
191          "change_decay()", "change_release()", "change_cutoff_attack()",
192          "change_cutoff_decay()", "change_cutoff_release()",
193          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
194          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
195          "change_pan_time()", instead imply 'final'ness at runtime and raise an
196          appropriate parser warning at parse time.
197        - Added built-in real number functions "round()", "ceil()", "floor()",
198          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
199          "cos()", "tan()", "asin()", "acos()", "atan()".
200        - Added built-in script real number constant "~NI_MATH_PI".
201        - Added built-in script real number constant "~NI_MATH_E".
202        - NKSP language: Allow unary '+' operator.
203        - Added built-in script functions "msb()" and "lsb()".

222        - Added NKSP int array and real array tests for value assignment and
223          initialization of arrays.
224        - Added NKSP test cases for built-in functions "round()", "ceil()",
225          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",

227        - Added NKSP test cases for unary '+' operator.
228    
229      * GigaStudio/Gigasampler format engine:
230        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
231          behaviour for start_level_mid.
232        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
233          level (see discussion "GigaStudio LFO compatibility" on mailing list
234          from 2019-09-26 for details).
235        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
236          see discussion "GigaStudio LFO compatibility" on mailing list from
237          2019-09-26 for details).
238        - Format extension: Added support for different LFO wave forms (currently
239          either sine [default], triangle, saw or square).
240        - Format extension: Added support for LFO phase displacement (0°..360°).
241        - Format extension: Added support for flipping LFO polarity on LFO 3
242          (in the original gig format this was only available for LFO 1 and LFO 2).
243        - Format extension: Support for additional filter types:
244          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
245          bandreject 2-pole.
246    
247      * SFZ format engine:
248        - Fixed support for regions with loccN/hiccN conditions on more than one
249          MIDI controller.
250    
251      * Benchmarks:
252        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
253          algorithm (since result of 2nd run was not accumulated).
254        - Added benchmark for saw wave (benchmarks/saw.cpp).
255        - Added benchmark for sine wave (benchmarks/sine.cpp).
256        - Added benchmark for square wave (benchmarks/square.cpp).
257        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
258          which are large enough on modern systems.
