32        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
33          on the process's main thread
34        - fixed build error on newer MinGW
35        - support building with older jack versions
36        - support building with spaces in vst sdk path
37        - enabled automake 'subdir-objects' option and moved external
38          source references (vst, au, asio) from makefiles to cpp files,
39          in order to get rid of warnings from automake 1.14
40    
41      * general changes:
42        - Refactoring: moved the independent code from
43          the Gigasampler format engine to base classes
44        - command line option '--profile' is currently disabled, since the
45          respective profiling code is currently broken
46        - Introduced support for optional environment variable
47          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48          where the sampler shall look for instrument editor plugins
49          (patch by Luis Garrido, slightly modified).
50        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53          note (in this implementation of the sampler its simply hard routed to
54          the 1st effect send of the sampler channel, no matter what the actual
55          effect type is)
56        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57          note (in this implementation of the sampler its simply hard routed to
58          the 2nd effect send of the sampler channel, no matter what the actual
59          effect type is)
60        - implemented support for internal LADSPA effects
61        - raised limit of program change queue from 100 to 512
62          (as suggested by Alex Stone)
63        - implemented sine LFO, pulse LFO and saw LFO
64        - experimental support for per voice equalization
65        - 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.
102        - Aftertouch: extended API to explicitly handle channel pressure and
103          polyphonic key pressure events (so far polyphonic pressure was not
104          supported at all, and channel pressure was rerouted as CC128 but not
105          used so far).
106        - Added initial support for real-time instrument scripts. The script VM
107          code is shared by all sampler engine implemementations, however only the
108          gig file format currently provides support for storing instrument scripts
109          (as LinuxSampler extension to the original GigaStudio 4 format).
110    
111      * Gigasampler format engine:
112        - implemented the "round robin keyboard" dimension
113        - fixed round robin and random dimensions for cases when number of
114          dimension zones is not a power of two
115        - made round robin use a counter for each region instead of each
116          key
117        - bugfix: pitch LFO controller "internal+aftertouch" was broken
118        - bugfix: filter keyboard tracking was broken
119        - filter performance fix (an unnecessary copy was made of the
120          filter parameters in each sub fragment)
121        - handle special case when pan parameter in gig file has max or
122          min value
123        - Exclusive Groups: don't ever stop voices of the same note,
124          doesn't sound naturally with a drumkit
125        - fixed EG1 modulation when attack or release is zero
126        - Fixed support for 'aftertouch' attenuation controller.
127        - Fixed crash that happened with velocity split sounds under certain
128          conditions (see also previous commit on libgig).
129    
130      * SFZ format engine:
131        - Initial implementation (not usable yet)

133        - added a fine-tuned v1 envelope generator instead of using the
134          one from the gig engine

136        - added support for trigger=first, trigger=legato and sw_previous
137        - allow non-numerical key values ("C#4" for example)
138        - "key" opcode now sets pitch_keycenter too
139        - fixed error when unloading instrument with same sample used by
140          multiple regions

148        - fine-tuned the default velocity curve
149        - added support for transpose
150        - fixed crash when using sw_down/up
151        - improved logic for sw_lokey/hikey/up/down/last
152        - added more v1 aliases to parser
153        - reduced memory usage for sfz data
154        - RT-safeness: avoid malloc in audio thread
155        - fixed a bug that could cause voice stealing to fail
156        - optimized sample lookup

289          (modified patch which was originally posted by Sergey on LS mailing list)
290        - bugfix: generation of velocity curves etc should not be done
291          after each "#include", only after the main file is parsed
292        - bugfix: line numbers in error messages were wrong after "#include"
293    
294      * SoundFont format engine:
295        - Initial implementation (not usable yet)
296        - RT-safeness: avoid malloc in audio thread
297        - fixed a bug that could cause voice stealing to fail

300        - initial implementation of cutoff filter
301        - use linear decay and release for filter and pitch EG
302    
303      * Host plugins (VST, AU, LV2, DSSI):
304        - AU bugfix: failed to destroy its audio/MIDI devices
305        - Listen to all interfaces on Mac OS X (INADDR_ANY)
306        - VST bugfix: If the host called resume() before and after
307          changing sample rate or block size, the number of channels was
308          incorrectly set to two. This caused silence in Cubase 5.
309        - save engine type (gig, sfz or sf2) in plugin state
310        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
311          64 bit Windows
312        - AU: changed number of output channels from one stereo to 16
313          stereo
314        - VST: made it possible to build the VST plugin for Mac
315        - AU: link AU plugin dynamically if --disable-shared isn't
316          specified
317        - LV2 "state" extension support (patch by David Robillard)
318        - VST bugfix: instrument loading hang and crashed the host when
319          the plugin was loaded a second time (#174)
320        - plugin bugfix: instrument loading hang when the plugin was
321          loaded a second time (this time it's for Linux and Mac, previous
322          similar fix was for Windows)
323        - thread safety fixes for the instrument loading thread
324        - LV2: use the new lv2 package if present
325        - VST: try to open Fantasia automatically on Linux and Mac too (on
326          Linux, the Fantasia jar should be placed in <prefix>/share/java)
327        - VST: fixed crashes on Linux Ardour and EnergyXT
328        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
329          port and audio channel routing for DSSI plugins are now visible.

349          to them a la JACK, via the usual sampler APIs
350        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
351          the driver will automatically connect to other CoreMIDI clients' ports

470        - minor valgrind fixes
471        - fixed crash which occurred when changing an already deployed sampler
472          channel to a different engine type
473        - fixed crash when deleting a sampler channel or changing engine
474          type while an instrument load was in progress
475        - bugfix: playing a note while changing the instrument could cause
476          a crash, or give "Handing back unknown region" error messages
477        - bugfix: calling SET VOICES (which Fantasia does on start and
478          refresh) could cause instruments to be unloaded
479        - Mac OS X: fixed name collision of enum in EffectControl and
480          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
481        - Mac OS X: fixed hanging threads
482        - Windows: disabled the previous thread fix on non-Mac systems, as
483          it caused hanging threads on Windows
484        - Fixed possible crashes due to corrupted MIDI/audio device list
485          after MIDI/audio device creation failure
486        - When creating MIDI instrument map entries with "PERSISTENT" type, the
487          instruments were uselessly precached with zero samples, however it still
488          took the full preloading time and on 1st program change the respective
489          instrument was completely reloaded again.
490        - fixed handling of rapid bank select and program change messages
491          sent to the same sampler channel (patch from the Open Octave
492          project, slightly adjusted)
493        - fixed crash when trying to create an effect instance with controls
494          which min and/or max values depend on the sample rate

505          introduced in previous fix)
506        - fixed crash when a channel received a program change while
507          playing a note in a key group
508        - fixed erroneous error message piping in VoiceBase.h
509          (labelled "Disk stream not available in time")
510        - Update effects on sample rate & period size changes (to avoid
511          crashes and noise on such transitions).
512        - ignore missing LADSPA paths without ignoring valid LADSPA paths
513          (fixes #208)
514        - Fixed bug in LSCP grammar definition which caused a statement like
515          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
516          practically irrelevant, however it caused problems with the new LSCP
517          shell's auto completion feature).
518    
519    Version 1.0.0 (31 July 2009)
520    
521      * packaging changes:
522        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
523          causing e.g. the libgig test to fail when
524          "./configure --disable-jack-driver" was used
525          (patch by Alexis Ballier)
526        - fixed compilation with gcc 4.3
527        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
528        - fixed configure so it detects x86_64 (#107)
529        - fixes for building with newer MinGW versions
530        - fix for building with bison 2.4 (#111)
531        - fixed building with libgig installed in a non-standard directory
532        - minor fix in configure for mmsystem.h detection on MinGW
533        - Windows: look for editor plugins and Fantasia using base
534          directory of liblinuxsampler dll (look in the same directory and one
535          directory above)
536        - configure script fix: removed unconditional use of SSE
537        - fixed building with sqlite installed in a non-standard directory
538        - when cross-compiling, don't try to create instruments.db
539        - fix for new mingw-w64 version, which has usleep
540    
541      * general changes:
542        - bugfix: on some POSIX systems instrument editor plugins refused to
543          load as we used a non-portable Linux specific struct field
544          (fixes bug #70, patch by Ronald Baljeu)
545        - fixed endless loop which occured when loading an instrument editor
546          plugin DLL on Windows systems failed
547        - fixed memory leaks that occurred when liblinuxsampler was unloaded
548        - optimized the SynchronizedConfig class so it doesn't wait
549          unnecessarily long after an update
550        - added support for notifying instrument editors on note-on / note-off
551          events (e.g. to highlight the pressed keys on the virtual keyboard
552          of gigedit)
553        - added support for triggering notes by instrument editors (see above)
554        - be verbose on DLL load errors (on Linux)
555        - fixed di-harmonic triangle LFO implementation (this LFO implementation
556          is only used by very few systems, most pick the int math
557          implementation, which is usually faster)
558        - fixes for audio drivers with varying buffer sizes
559        - experimental support for running LinuxSampler as a DSSI, LV2 and
560          VST plugin
561        - notification events for stream/voice count statistics are now sent
562          only when there are actual changes
563        - added memory ordering constraints to improve stability on
564          multi-core and multi-cpu systems
565        - maximum voices and disk streams can now be altered at runtime
566        - fixed CPU feature detection on x86_64 (maybe fixes #108)
567        - automatic stacktrace mechanism is now turned off by default and can
568          be switched on by command line option "--stacktrace" (the automatic
569          stacktrace mechanism seems to be broken on most systems at the moment)
570        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
571          a pointer to the launched InstrumentEditor object
572        - added optional 3rd party user data parameter for following
573          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
574          InstrumentEditor::Launch(),
575          InstrumentManager::LaunchInstrumentEditor()
576        - theoretical fix: made SynchronizedConfig follow C++0x memory
577          model more strictly
578        - fixes for using large audio device buffers
579        - Windows: add the installation directory to the DLL search path
580          when loading an editor plugin (solves problems with VST and
581          gigedit on systems with other GTK versions installed)
582        - updated linuxsampler man page
583    
584      * audio driver:
585        - removed the nonsense audio channel constraint (which was hard coded to
586          max. 100 audio channels) for most audio drivers
587        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
588          opposed to the LSCP specs
589        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
590          reflected the wrong value
591        - fixed a memory management bug in ASIO driver
592        - Makefile fix: JACK_CFLAGS wasn't used
593        - JACK: use jack_client_open instead of the deprecated
594          jack_client_new
595        - added (experimental) CoreAudio driver
596        - applied old fixes to the ASIO driver that were included in the
597          previous binary release but accidentally never committed to CVS
598          (fixes #117)
599        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
600          win64)
601        - VST: added support for sample rate and buffer size changes
602        - VST: close editor (Fantasia) when the VST is removed
603        - VST: avoid opening Fantasia more than once for each VST instance
604        - VST: export main function as "main" on Linux too (fix for
605          energyXT)
606        - VST: changed number of output channels from one stereo to 16
607          stereo
608        - added channel routing, fxsends and midi maps to the settings
609          stored in the plugin state
610        - performance optimization of AudioChannel::MixTo() and
611          AudioChannel::CopyTo() methods using GCC vector exensions
612          (if available)
613        - ASIO fixes: avoid initializing the device twice, avoid throwing
614          exception when getting parameters from a disconnected device
615    
616      * MIDI driver:
617        - added JACK MIDI driver
618        - dispatch bank select as ordinary CC as well, the user might seriously
619          want to (mis)use it for some purpose ("fixed" in all current MIDI
620          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
621        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
622          CoreMidi or AU
623        - fixed mingw-w64 compilation error in MME driver
624        - made program change handling in MIDI thread real-time safe by
625          moving the logic to a non-RT thread
626        - fixed minor memory leak in ALSA driver
627    
628      * instruments database:
629        - avoid time consuming samples scanning when adding instruments
630          to the instruments database
631        - added support for handling lost files in the instruments database
632        - Implemented option for adding instruments in separate directories
633          in the instruments database
634          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
635        - work-around for missing fnmatch function on Windows to make
636          instrument database compilable
637        - added instrument database support on Windows
638          works with both standalone mode and VST plugin.
639          the instruments DB file is located in
640          %USERPROFILE%\.linuxsampler\instruments.db which allows different
641          databases for each windows user
642          if no DB is present it automatically creates the .linuxsampler subdir
643          and then creates an empty DB
644        - fixed recursive import, which was broken on Windows
645    
646      * Gigasampler format engine:
647        - fixed a memory leak that could happen when a channel was deleted
648          while notes were playing
649        - made it possible to load an instrument even if the audio thread
650          isn't running
651        - added partial support for the "Controller Triggered" MIDI rule,
652          enough for piano gigs with pedal noise samples
653        - minor fix: only mark FX sends as being modified if really the
654          respective FX send MIDI controller was used
655        - added support for GM global device volume SysEx message
656          (can be selected at compile time to either apply globally to the
657          whole sampler [default] or only to the sampler channels that are
658          connected to the respective MIDI input port the SysEx message arrived
659          on)
660        - bugfix: notes triggered at position 0 in the audio buffer were
661          sometimes wrongly killed in the same buffer, causing no sound to
662          be played
663        - added support for chromatic / drumkit mode Roland GS Sysex message
664          which is usally used to switch a part between chromatic sounds and
665          drumkit sounds (as opposed to their common default setting of MIDI
666          part 10 being a drumkit part and all other ones chromatic parts), in
667          LS however one can switch between the first 16 MIDI instrument maps
668          defined for the sampler
669        - made it possible to create multiple sample channels even if the
670          audio thread isn't running
671        - fixed crash when removing channel with active voices (#116)
672        - bugfix: on sample reference changes (instrument editor), only
673          un-cache the respective sample if it's really not used by any
674          sampler engine anymore
675        - re-cache samples in case they were changed by an instrument editor,
676          e.g. when a sample was added while playing (#82)
677        - fixed hanging notes which occured when note-off event had the exact
678          same time stamp as the voice's note-on event and occured both in the
679          same audio fragment cycle (fixes bug #112)
680        - added support for the "fine tune" and "pitch bend range"
681          instrument-level gig parameters
682        - fixed minor artifacts in pitch bend handling
683        - added support for GS Reset SysEx message
684        - allow gig files to use unlimited downward pitch shifting
685        - added a limit check for upward pitch shifting
686        - bugfix: sometimes, when playing a note twice fast, the second
687          note was silent
688        - fixed crash happening when a pitch bend event arrived at the
689          same time a new instrument was loading
690    
691      * LSCP server:
692        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
693          react on MIDI data arriving on certain sampler channels (so far only
694          Note-On and Note-Off events are sent via this LSCP event)
695        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
696          react on MIDI data arriving on certain MIDI input devices (so far only
697          Note-On and Note-Off events are sent via this LSCP event)
698        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
699          SET DB_INSTRUMENT FILE_PATH
700        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
701          frontends to send MIDI messages to specific sampler channel
702        - added two additional fields to GET FILE INSTRUMENT INFO command -
703          KEY_BINDINGS and KEYSWITCH_BINDINGS
704        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
705          was incorrect
706        - Optimized the retrieval of the MIDI instrument mappings
707        - added new LSCP command "SET VOICES" to globally alter the maximum
708          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
709          be triggered respectively
710        - added new LSCP command "SET STREAMS" to globally alter the maximum
711          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
712          which will be triggered respectively
713        - bugfix: retry if "select" returns EINTR (this fixes a crash when
714          a gigedit file dialog is opened)
715        - close all connections when LSCPServer is deleted
716        - hard close of all sockets on exit
717        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
718          driver
719    
720      * Bug fixes:
721        - fixed a crash which occurs when removing a sampler channel waiting
722          to start instrument loading after another channel
723        - fixed a crash which occurs when removing a sampler channel with
724          instrument loading in progress (bug #113)
725        - fixed termination caused by uncaught exception when adding MIDI
726          instrument with PERSISTENT load mode
727        - fixed possible iterator invalidations when resetting the sampler
728        - fixed memory leaks when issuing the following LSCP commands:
729          GET AUDIO_OUTPUT_DRIVER INFO
730          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
731          GET MIDI_INPUT_DRIVER INFO
732          GET MIDI_INPUT_DRIVER_PARAMETER INFO
733        - fixed possible compilation error when sqlite is not present
734        - fixed orphaned pointers when setting maximum voices limit (bug #118)
735        - fixed crash when changing the audio output device of a sampler
736          channel with loaded instrument and start playing notes
737        - fixed endless loop in Engine::SuspendAll() (bug #120)
738        - fixed a low-level atomic load function that was broken on 64-bit
739          PowerPC, which probably could cause crashes on that platform
740        - fixed a memory management error which could cause a crash when a
741          plugin was unloaded
742        - bugfix: two private structs had the same name, which could cause
743          problems if the linker chose the wrong constructor
744        - fixed low-level ConditionServer usage bug that caused lockups on
745          Windows
746    
747    
748    Version 0.5.1 (6 December 2007)
749    
750      * packaging changes:
751        - added autoconf checks for pthread library
752        - added autoconf check for pthread bug found on certain NPTL-enabled
753          glibc versions (see Gentoo bug report #194076)
754        - added autoconf checks for MS Windows
755    
756      * general changes:
757        - bugfix: the thread used by an editor plugin didn't die when the
758          editor closed
759        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
760          out all the space. operator--() did not apply size_mask after
761          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
762          order to avoid problems with the _NonVolatileReader functions.
763        - bugfix: Stream.h: added a missing divide by BytesPerSample in
764          GetWriteSpace(). Since this function is currently only used in
765          the stream's qsort() compare function, it didn't trigger any
766          bugs.
767        - Resampler.h, Synthesizer.h: cubic interpolation now works in
768          24bit mode too. Faster method to read 24bit words on little
769          endian machines (x86): replaced 3 byte reads + shifts with a 1
770          unaligned 32bit read and shift
771        - experimental support for MS Windows (MIDI input via MME, AUDIO
772          output via ASIO)
773        - made handling of SIGINT signal (Ctrl-C) a bit more robust
774        - support for monitoring the total number of active disk streams
775          (new LSCP commands: GET TOTAL_STREAM_COUNT,
776          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
777    
778      * AUDIO driver:
779        - added Windows ASIO low latency audio driver
780    
781      * MIDI driver:
782        - added MME Windows MIDI driver
783    
784      * LSCP server:
785        - added support for Windows style path / filenames, however with
786          forward slash path separators instead of backslash
787          (i.e. "C:/foo/bar.gig")
788        - allow naughty liblscp to send non-string device parameters within
789          apostrophes as well
790        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
791          "LIST FILE INSTRUMENTS <file>" and
792          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
793          about an arbitrary instrument file on the system where the sampler is
794          running on
795    
796    Version 0.5.0 (15 October 2007)
797    
798      * packaging changes:
799        - config.h is not going to be installed along with liblinuxsampler's
800          API header files anymore
801        - only the API relevant header (and source) files will be exported to
802          the Doxygen API documentation (explicitly listed in Doxyfile.in)
803        - added completely new XCode project files for Mac OSX which is now
804          capable to execute our autoconf environment, thus no need anymore
805          to maintain the compile time configuration file (osx/version.h) for
806          OSX manually (patch by Toshi Nagata)
807        - fixed buggy boolean --enable-foo / --disable-foo configure script
808          parameters
809        - global.h now only covers global definitions that are needed for the
810          C++ API header files, all implementation internal global definitions
811          are now in global_private.h
812        - atomic.h is not exposed to the C++ API anymore
813        - no need to include config.h anymore for using LS's API header files
814        - fixed warnings in API doc generation

843        - Implemented new, improved notification system
844        - fixed compilation errors regarding OSX
845          (patch by Toshi Nagata)
846        - implemented instruments database
847        - added support for escape sequences to the instruments database
848        - added highly experimental support for on-the-fly instrument editing
849          within the sampler's process (by using instrument editor plugins),
850          you'll notice the new "Registered instrument editors:" message on
851          startup, added a new LSCP command:
852          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
853          to spawn a matching instrument editor for the instrument on the
854          given sampler channel, the plugin path can be overridden at compile
855          time with ./configure --enable-plugin-dir=/some/dir
856        - added experimental code for synchronizing instrument editors hosted
857          in the sampler's process to safely edit instruments while playing
858          without a crash (hopefully) by either suspending single regions
859          wherever possible or if unavoidable whole engine(s)
860        - fixed several issues in fundamental "Thread" class: set scheduling
861          policy and priority on thread level, set a minimum stack size for
862          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
863          threads simply inherited properties of starting thread instead of
864          setting their own policy and priority
865        - minor fix in our automatic stack trace mechanism on crashes, the
866          main process did not wait for the stack trace process to finish
867          its output
868        - fixed some minor memory leaks
869        - reenabled assembly features support, at the moment only for
870          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
871        - minor assembly fix in x86 features detection (don't use the PIC
872          register, to avoid relocations in the text segment at runtime)
873        - POSIX callback functions of Thread.h are hidden
874

892      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
893        - EG fine tuning: when attack is zero the EG starts at a level
894          above max sustain level, which means that there is a decay phase
895          even if sustain is 100%
896        - more EG fixes: the level could sometimes go below zero and cause
897          noises or crashes
898        - minor fix of EGDecay (patch by Toshi Nagata)
899        - fixed compiler error when --enable-override-filter-type was
900          supplied to the configure script (fixes #46)
901        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
902          instead of a fix value
903        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
904          127 (solo mode) only kill voices if the respective mode really
905          changed
906    
907      * LSCP server:
908        - fixed compile time error for old Bison versions
909          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
910        - parser now supports extended ASCII character set
911          (up to ASCII code 255, i.e. includes now umlauts and accents)
912        - filename arguments in LSCP commands now allow to use escape
913          sequences, that is directly literal as one of: \', \", \\, \n, \r,
914          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
915          code value like \xf2) (fixes bug #24)
916        - the following LSCP commands now also support escape sequences for at
917          least one of their text-based parameters (i.e. name, description):
918          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
919          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
920          "SET DB_INSTRUMENT_DIRECTORY NAME",
921          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
922          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
923          "FIND DB_INSTRUMENT_DIRECTORIES"
924        - returns verbose syntax errors (line and column where syntax error
925          occured, the unexpected character and the actually expected, possible
926          character(s), the latter only if less than 5 possibilities)
927        - made sure that LSCP syntax is not affected by gigedit locale
928          settings
929        - bugfix regarding strings parameter lists: all comma separated lists
930          of strings were treated as being one string containing commas
931          (fixes #57)
932    
933    * Bug fixes:    * Bug fixes:
934      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)

937        - fixed a crash which occurs when reassigning the same engine
938          on a sampler channel with connected MIDI device
939        - fixed a crash which occurs when changing the number of ports of a MIDI
940          device connected to a sampler channel to number less then or equal
941          to the index of the port to which the sampler channel is connected.
942        - The previous bindings were not been disconnected when altering
943          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
944          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
945        - The active stream/voice count statistic was incorrect.
946        - notification events were not been sent for some sampler
947          channel changes
948        - added default min and max values to restrict the number of allowed
949          audio output channels and MIDI input ports
950        - the connection to the PCM interface is now closed when destroying
951          an audio output device
952        - files with slash in their path or filename could not be loaded
953    
954      * test cases:
