63      - implemented sine LFO, pulse LFO and saw LFO      - implemented sine LFO, pulse LFO and saw LFO
64      - experimental support for per voice equalization      - experimental support for per voice equalization
65      - added command line option --exec-after-init      - added command line option --exec-after-init
66        - Introduced new C++ API method:
67          EngineChannel::InstrumentFileName(int index)
68          allowing to retrieve the whole list of files used for the loaded
69          instrument on an engine channel (a.k.a. part). Some GigaStudio
70          instruments for example are splitted over several files like
71          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72        - Added new C++ API method Sampler::GetGlobalMaxVoices().
73        - Added new C++ API method Sampler::GetGlobalMaxStreams().
74        - Added new C++ API method Sampler::SetGlobalMaxVoices().
75        - Added new C++ API method Sampler::SetGlobalMaxStreams().
76        - Various "const" and "restrict" optimizations.
77        - all engines: add pan CC value to instrument pan parameter before
78          applying panning, instead of using two separate pan functions in
79          series (#182)
80        - added a lock guard class for exception safe mutex handling and
81          used it everywhere appropriate
82        - Immediately apply scale tuning changes to active voices.
83        - Exposed scale tuning to C++ API (along to the already existing standard
84          SysEx way).
85        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86          and broken for ppc64. (Seq_cst loads and stores are actually not
87          used in LS, so the bug wasn't noticable.)
88        - lsatomic.h: added ARMv7 support
89        - Added support for multiple MIDI input ports per sampler channel (and
90          added various new C++ methods for this new feature / design change, old
91          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92          as deprecated but are still there and should provide full behavior
93          backward compatibility).
94        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95          unsafe and caused compilation error with clang 2.x).
96        - Bugfix: only process the latest MIDI program change event.
97        - Introducing the LSCP shell, which provides convenient control of the
98          sampler from the command line by providing LSCP aware features.
99        - VirtualMidiDevice: Added support for program change.
100        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
101        - VirtualMidiDevice: Added support for pitch bend.

113        - handle special case when pan parameter in gig file has max or
114          min value

449        - Fixed bug in LSCP grammar definition which caused a statement like
450          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
451          practically irrelevant, however it caused problems with the new LSCP
452          shell's auto completion feature).
