2    
3      * general changes:
4        - Fixed compiler error in Pool.h.
5        - Require C++11 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++11 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++11).
10    
11      * Real-time instrument scripts:
12        - Added method ScriptVM::setExitResultEnabled() which allows to
13          explicitly enable the built-in exit() function to optionally accept
14          one function argument; the value of the passed exit() function
15          argument will then become available by calling
16          VMExecContext::exitResult() after script execution.
17        - 64 bit support for NKSP integer scripts variables (declare $foo).
18        - Variable names, function names and preprocessor condition names must start
19          with a regular character (a-z or A-Z); starting them with a digit or
20          underscore is not allowed.
21        - NKSP parser fix: equal comparison operator "=" and not equal comparison
22          operator "#" must only accept integer operands.
23        - NKSP language: Implemented support for standard units like Hertz, seconds,
24          Bel including support for metric unit prefixes; so one can now e.g.
25          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
26          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
27          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
28        - NKSP language: Introduced "final" operator "!" which is specifically
29          intended for synthesis parameter values to denote that the synthesis
30          parameter value is intended to be the "final" value for that synthesis
31          parameter that should explicitly be used by the engine and thus causing
32          the sampler engine to ignore all other modulation sources for the same
33          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
34          variable or formula with this new "!" operator the expression is marked as
35          being "final".
36        - NKSP script editor API: Added support for detecting standard unit tokens
37          and their potential metric prefix token.
38        - NKSP language: Added support for NKSP real number literals and
39          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
40        - NKSP language: Added support for NKSP real number (floating point) script
41          variables (declare ~foo).
42        - NKSP language: Added support for NKSP real number (floating point) array
43          script variables (declare ?foo[]).
44        - Built-in script function "message()" accepts now real number argument as
45          well.
46        - Added built-in script function "real_to_int()" and its short hand form
47          "int()" for casting from real number to integer in NKSP scripts.
48        - Added built-in script function "int_to_real()" and its short hand form
49          "real()" for casting from integer to real number in NKSP scripts.
50    
51      * test cases:
52        - Fixed compiler errors in test cases.
53        - Updated README for how to compile & run test cases.
54        - Updated test case
55          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
56          expected behaviour of the Mutex class implementation (recursive
57          mutex type).
58        - Added test cases for NKSP core language aspects and core built-in
59          functions.
60        - Fixed thread tests segfaulting on Linux.
61    
62    Version 2.1.1 (27 Jul 2019)
63    
64      * Real-time instrument scripts:
65        - Fixed behavior of built-in NKSP functions change_sustain(),
66          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
67          and change_cutoff_release().
68    
69      * general changes:
70        - Only play release trigger samples on sustain pedal up if this behaviour
71          was explicitly requested by the instrument (otherwise only on note-off).
72        - Fixed compiler warnings.
73        - Fixed compilation error when cross-compiling to Mac.
74        - FX Sends: Provide more useful error messages on routing problems
75          (see bug #169).
76        - LSCP doc: Be more clear describing the two distinct approaches
77          of using external vs. internal effects (see bug #169).
78        - "optional" class: Fixed comparison operators.
79    
80      * Gigasampler/GigaStudio format engine:
81        - Format extension: If requested by instrument then don't play release
82          trigger sample on note-off events.
83    
84      * SFZ format engine:
85        - Fixed memory leak when releasing samples
86          (fixes bug #307, patch by Jacek Roszkowski)
87        - Fixed potential crash when a sample is shared by more than one region
88          (fixes bug #308, patch by Jacek Roszkowski).
89        - Opcode 'sample': Added support for built-in sample '*silence'
90          (fixes bug #310, patch by Jacek Roszkowski).
91    
92    Version 2.1.0 (25 Nov 2017)

105        cutoff settings.        cutoff settings.
106        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
107          all if an up-pitch of more than 40 semi tones was requested (I don't
108          think there is any stock gig sound that requires this behavior to
109          resemble its original sound).
110        - Added support for controlling whether the individual EGADSR stages may
111          be aborted (as LinuxSampler extension to the original GigaStudio 4
112          format).

151        - linuxsampler binary fix: option --create-instruments-db ignored
152          subsequent optional argument due to glibc's implementation oddity
153          which expects a "=" sign, but no space between them.
