19        - Active voices are now internally grouped to "Note" objects, instead of
20          being directly assigned to a keyboard key. This allows more fine graded
21          processing of voices, which is i.e. required for certain instrument
22          script features.
23        - Fix: Release trigger voices were not spawned on sustain pedal up
24          (CC #64) events.
25        - Fix: Release trigger voices can now also distinguish correctly between
26          note-off and sustain pedal up events.
27        - All engines: Increased ramp speed of volume smoother and pan smoother
28          (while slow rate of crossfade smoother is preserved) to allow quick
29          volume and pan changes by instrument scripts for instance.
30        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
31          properly and thus were ignored for certain uses.
32        - Added new C++ API method
33          VirtualMidiDevice::SendChannelPressureToSampler().
34        - windows, 32-bit: fixed potential crashes by making sure the stack in
35          sub threads is 16-byte aligned
36        - fixed numerous compiler warnings

41        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
42          auto detect whether it (sh/c)ould output its messages in color.

56        variable.        variable.
57        - Built-in script function "play_note()": Added support for passing
58          special value -1 for "duration-us" argument, which will cause the
59          triggered note to be released once the original note was released.
60        - Instrument script classes now exported with the liblinuxsampler C++ API.
61        - Added new API method ScriptVM::syntaxHighlighting() which provides
62          a convenient syntax highlighting backend for external instrument
63          script editor applications.
64        - Added new C++ API class "ScriptVMFactory".
65        - Extended parser issues to provide not only first line and first
66          column, but also last line and last column of issue (thus marking
67          the precise span of the issue within the source code).
68        - Reload script automatically after being modified by an instrument
69          editor.
70        - NKSP language grammar correction: allow empty event handler bodies
71          like "on note end on".
72        - Implemented built-in script function "change_vol()".
73        - Implemented built-in script function "change_tune()".
74        - Implemented built-in script function "change_pan()".
75        - Implemented built-in script function "change_cutoff()".
76        - Implemented built-in script function "change_reso()".
77        - Implemented built-in script function "event_status()".
78        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
79          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
80          "event_status()" function.
81        - NKSP language: Added support for bitwise operators ".or.", ".and."
82          and ".not.".
83        - NKSP language scanner: Fixed IDs matching to require at least one
84          character (i.e. when matching function names or variable names).
85        - NKSP language scanner: disabled unusued rules.
86        - Fixed behavior of play_note() and note_off() functions which must
87          be distinguished engine internally from "real" MIDI note on/off
88          events in order to avoid misbehaviors like hanging notes.
89        - Implemented built-in script variable "$KSP_TIMER".
90        - Implemented built-in script variable "$NKSP_REAL_TIMER".
91        - Implemented built-in script variable "$NKSP_PERF_TIMER".
92        - Implemented built-in script variable "$ENGINE_UPTIME".
93        - Implemented built-in script function "inc()".
94        - Implemented built-in script function "dec()".
95        - NKSP language fix: division expressions were evaluated too often.
96        - NKSP language fix: string concatenation operator was right
97          associative instead of left (to right).
98        - NKSP language correction: allow empty statements in entire language
99          (i.e. "if end if").
100        - Implemented built-in script function "stop_wait()".
101        - Implemented built-in script variable "$NI_CALLBACK_ID".
102        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
103        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
104        - Added support for read-only built-in variables (respectively
105          handled by the script parser).
106        - Added built-in script constant "$NI_CB_TYPE_INIT".
107        - Added built-in script constant "$NI_CB_TYPE_NOTE".
108        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
109        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
110        - NKSP Language: Added support for user defined script functions.
111        - Implemented built-in script function "change_attack()".
112        - Implemented built-in script function "change_decay()".
113        - Implemented built-in script function "change_release()".
114        - Fixed all change_*() built-in script functions to apply their
115          synthesis parameter changes immediately in case the respective note
116          was triggered at the same time, instead of scheduling the parameter
117          change, especially because it would cause some parameter types's
118          changes either to be ramped (i.e. change_vol()) or other types even
119          to have not effect at all (i.e. change_attack()).
120        - Implemented built-in script function "sh_left()".
121        - Implemented built-in script function "sh_right()".
122        - Implemented built-in script function "min()".
123        - Implemented built-in script function "max()".
124        - NKSP Fix: "init" event handler was not always executed when a script
125          was loaded.
126        - NKSP built-in wait() script function: abort script execution if
127          a negative or zero wait time was passed as argument (since this is
128          a common indication of a bug either of the script or even of the
129          engine, which could lead to RT instability or even worse).
130        - ScriptVM: Implemented automatic suspension of RT safety
131          threatening scripts.
132        - Provide more user friendly error messages on syntax errors.
133        - Fixed NKSP parser warning "Not a statement" when assigning an
134          initializer list to an array variable.
135    
136      * Instruments DB:
137        - Fixed memory access bug of general DB access code which lead to
138          undefined behavior.
