4      - added support for <global>, <master> and #define (patch by Alby M)      - added support for <global>, <master> and #define (patch by Alby M)
5        - Removed code duplication in SFZ file loading code.
6        - Added support for sfz extension opcode 'script' which may be used to
7          load real-time instrument script file (NKSP script language).
8        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9        - Fixed unintended volume fade-in of voices under certain conditions.
10        - sfz parser: allow missing space between header and opcode
11    
12      * Gigasampler/GigaStudio format engine:
13        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
14          cutoff settings.
15        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
16          all if an up-pitch of more than 40 semi tones was requested (I don't
17          think there is any stock gig sound that requires this behavior to
18          resemble its original sound).
19        - Added support for controlling whether the individual EGADSR stages may
20          be aborted (as LinuxSampler extension to the original GigaStudio 4
21          format).

39        script features.        script features.
40        - Fix: Release trigger voices were not spawned on sustain pedal up
41          (CC #64) events.
42        - Fix: Release trigger voices can now also distinguish correctly between
43          note-off and sustain pedal up events.
44        - All engines: Increased ramp speed of volume smoother and pan smoother
45          (while slow rate of crossfade smoother is preserved) to allow quick
46          volume and pan changes by instrument scripts for instance.
47        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
48          properly and thus were ignored for certain uses.
49        - Added new C++ API method
50          VirtualMidiDevice::SendChannelPressureToSampler().
51        - windows, 32-bit: fixed potential crashes by making sure the stack in
52          sub threads is 16-byte aligned
53        - fixed numerous compiler warnings
54        - Fixed invalid (note-on) event ID being assigned to new Note objects.
55        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
56          fixes potential undefined behavior.
57        - Fixed Note object leak when triggering notes on keys which did not
58          have a valid sample mapped (fixes bug #252).
59        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
60        - linuxsampler binary fix: option --create-instruments-db ignored
61          subsequent optional argument due to glibc's implementation oddity
62          which expects a "=" sign, but no space between them.

112        - NKSP language: Added support for bitwise operators ".or.", ".and."
113          and ".not.".
114        - NKSP language scanner: Fixed IDs matching to require at least one
115          character (i.e. when matching function names or variable names).
116        - NKSP language scanner: disabled unusued rules.
117        - Fixed behavior of play_note() and note_off() functions which must
118          be distinguished engine internally from "real" MIDI note on/off
119          events in order to avoid misbehaviors like hanging notes.
120        - Implemented built-in script variable "$KSP_TIMER".
121        - Implemented built-in script variable "$NKSP_REAL_TIMER".
122        - Implemented built-in script variable "$NKSP_PERF_TIMER".

127        - NKSP language fix: string concatenation operator was right
128          associative instead of left (to right).
129        - NKSP language correction: allow empty statements in entire language
130          (i.e. "if end if").
131        - Implemented built-in script function "stop_wait()".
132        - Implemented built-in script variable "$NI_CALLBACK_ID".
133        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
134        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

146          synthesis parameter changes immediately in case the respective note
147          was triggered at the same time, instead of scheduling the parameter
148          change, especially because it would cause some parameter types's
149          changes either to be ramped (i.e. change_vol()) or other types even
150          to have not effect at all (i.e. change_attack()).

156          was loaded.
157        - NKSP built-in wait() script function: abort script execution if
158          a negative or zero wait time was passed as argument (since this is
159          a common indication of a bug either of the script or even of the
160          engine, which could lead to RT instability or even worse).
161        - ScriptVM: Implemented automatic suspension of RT safety
162          threatening scripts.
163        - Provide more user friendly error messages on syntax errors.
164        - Fixed NKSP parser warning "Not a statement" when assigning an

174        - Implemented built-in script function "fade_in()".
175        - Implemented built-in script function "fade_out()".
176        - Fixed acceptance of wrong data type of parameters passed to built-in
177          script functions "change_vol()", "change_tune()", "change_pan()",
178          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
179          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
180          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
181        - Added built-in script function "get_event_par()" and implemented some
182          of its possible parameter selections.
183        - Added built-in script function "set_event_par()" and implemented some
184          of its possible parameter selections.
185        - Fixed a bunch of scheduler time related bugs.
186        - Fixed polyphonic variables not being reset to zero after usage.
187        - Built-in "ignore_event()" function: argument is now optional, like with
188          built-in function "ignore_controller()".
189        - Implemented built-in script function "change_velo()".
190        - Implemented built-in script function "change_note()".
191        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
192          intuitive behavior if used in combination with "change_vol_time()" or
193          "change_tune_time()" respectively: now tuning/volume changes are only
194          assigned (without delay) immediately to a new note if the respective
195          timing function has not been called before, otherwise the volume/tuning
196          changes are automatically faded (before, only the event's time stamp was
197          relevant).

208         - built-in "play_note()" function now supports a sample playback start
209           offset with argument 3, where special value -1 means to use the regular
210           sample offset as defined by the instrument file.
211         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
212         - Built-in variable $EVENT_NOTE is now a read-only variable.
213         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
214         - built-in "play_note()" function now accepts -2 for its fourth argument
215           (note duration) which means the life time of the note shall be sticked
216           to the requested note number of argument 1.
217         - Fix: built-in "play_note()" function now returns 0 as result value if
218           -1 was passed for its fourth argument (note duration) and the respective
219           parent note is already gone.
220        - Implemented built-in script function "change_play_pos()".

229        - Fixed potential memory access bug and potential undefined behavior of
230          "init" event handlers.
231        - Print a time stamp along to each call of built-in function "message()".

233          to retrieve all code blocks filtered out by the preprocessor.
234        - Added built-in script function "fork()".
235        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
236        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
237        - Fixed potential crash when accessing dynamic built-in array variables.

242        - Removed max. value limitation of built-in functions "change_attack()",
243          "change_decay()" and "change_release()" to i.e. allow passing 2000000
244          for doubling the respective time.
245        - NKSP script editor syntax highlighting API: Fixed app termination due
246          to a lexer start condition stack underrun.

248          USE_CODE_IF_NOT() preprocessor statements.
249        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
