68      - implemented sine LFO, pulse LFO and saw LFO      - implemented sine LFO, pulse LFO and saw LFO
69      - experimental support for per voice equalization      - experimental support for per voice equalization
70      - added command line option --exec-after-init      - added command line option --exec-after-init
71        - Introduced new C++ API method:
72          EngineChannel::InstrumentFileName(int index)
73          allowing to retrieve the whole list of files used for the loaded
74          instrument on an engine channel (a.k.a. part). Some GigaStudio
75          instruments for example are splitted over several files like
76          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
77        - Added new C++ API method Sampler::GetGlobalMaxVoices().
78        - Added new C++ API method Sampler::GetGlobalMaxStreams().
79        - Added new C++ API method Sampler::SetGlobalMaxVoices().
80        - Added new C++ API method Sampler::SetGlobalMaxStreams().
81        - Various "const" and "restrict" optimizations.
82        - all engines: add pan CC value to instrument pan parameter before
83          applying panning, instead of using two separate pan functions in
84          series (#182)
85        - added a lock guard class for exception safe mutex handling and
86          used it everywhere appropriate
87        - Immediately apply scale tuning changes to active voices.
88        - Exposed scale tuning to C++ API (along to the already existing standard
89          SysEx way).
90        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
91          and broken for ppc64. (Seq_cst loads and stores are actually not
92          used in LS, so the bug wasn't noticable.)
93        - lsatomic.h: added ARMv7 support
94        - Added support for multiple MIDI input ports per sampler channel (and
95          added various new C++ methods for this new feature / design change, old
96          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
97          as deprecated but are still there and should provide full behavior
98          backward compatibility).
99        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
100          unsafe and caused compilation error with clang 2.x).
101        - Bugfix: only process the latest MIDI program change event.
102        - Introducing the LSCP shell, which provides convenient control of the
103          sampler from the command line by providing LSCP aware features.
104        - VirtualMidiDevice: Added support for program change.
105        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
106        - VirtualMidiDevice: Added support for pitch bend.
107        - Aftertouch: extended API to explicitly handle channel pressure and
108          polyphonic key pressure events (so far polyphonic pressure was not
109          supported at all, and channel pressure was rerouted as CC128 but not
110          used so far).
111        - Added initial support for real-time instrument scripts. The script VM
112          code is shared by all sampler engine implemementations, however only the
113          gig file format currently provides support for storing instrument scripts
114          (as LinuxSampler extension to the original GigaStudio 4 format).
115    
116    * Gigasampler format engine:    * Gigasampler format engine:

126        - handle special case when pan parameter in gig file has max or
127          min value
128        - Exclusive Groups: don't ever stop voices of the same note,
129          doesn't sound naturally with a drumkit
130        - fixed EG1 modulation when attack or release is zero
131        - Fixed support for 'aftertouch' attenuation controller.

298        - bugfix: line numbers in error messages were wrong after "#include"
299        - added support for float and 32 bit sample files

438        - Added support for moving cursor left/right with arrow keys.
439        - Added support for built-in LSCP reference documentation, which will

537        - ignore missing LADSPA paths without ignoring valid LADSPA paths
538          (fixes #208)
539        - Fixed bug in LSCP grammar definition which caused a statement like
540          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
541          practically irrelevant, however it caused problems with the new LSCP
542          shell's auto completion feature).
543        - Fixed MIDI program change messages being ignored if quickly executed
544          after each other (fixes #231).
