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).
27        - Renamed type LFOSigned -> LFOTriangleSigned.
28        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29        - Using now cubic interpolation as resampling algorithm by default; and
30          linear interpolation is deprecated now.
31        - Event:Init(): memset() entire Event::Param union to zero instead of trying
32          to do that for its individual members; the latter became error prone due
33          to the union's growing complexity meanwhile.
34        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36          methods and marked the old ones as deprecated; and likewise added new
37          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38          methods and marked those old ones deprecated as well.
39        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40          resolution for certain (e.g. hard coded) RPN and NRPN parameters.

210      - Added built-in script real number constant "~NI_MATH_PI".      - Added built-in script real number constant "~NI_MATH_PI".
211      - Added built-in script real number constant "~NI_MATH_E".      - Added built-in script real number constant "~NI_MATH_E".
212      - NKSP language: Allow unary '+' operator.      - NKSP language: Allow unary '+' operator.
213        - Added built-in script functions "msb()" and "lsb()".

236        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
237      - Added NKSP test cases for unary '+' operator.      - Added NKSP test cases for unary '+' operator.
238    
239      * GigaStudio/Gigasampler format engine:
240        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
241          behaviour for start_level_mid.
242        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
243          level (see discussion "GigaStudio LFO compatibility" on mailing list
244          from 2019-09-26 for details).
245        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
246          see discussion "GigaStudio LFO compatibility" on mailing list from
247          2019-09-26 for details).
248        - Format extension: Added support for different LFO wave forms (currently
249          either sine [default], triangle, saw or square).
250        - Format extension: Added support for LFO phase displacement (0°..360°).
251        - Format extension: Added support for flipping LFO polarity on LFO 3
252          (in the original gig format this was only available for LFO 1 and LFO 2).
253        - Format extension: Support for additional filter types:
254          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
255          bandreject 2-pole.
256    
257    * SFZ format engine:    * SFZ format engine:
258      - Fixed support for regions with loccN/hiccN conditions on more than one      - Fixed support for regions with loccN/hiccN conditions on more than one

260    
261      * Benchmarks:
262        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
263          algorithm (since result of 2nd run was not accumulated).
264        - Added benchmark for saw wave (benchmarks/saw.cpp).
265        - Added benchmark for sine wave (benchmarks/sine.cpp).
266        - Added benchmark for square wave (benchmarks/square.cpp).
267        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
268          which are large enough on modern systems.
