10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate

22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)

31        - fix for building with bison 3.0 (#202)
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).

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

290          (modified patch which was originally posted by Sergey on LS mailing list)
291        - bugfix: generation of velocity curves etc should not be done
292          after each "#include", only after the main file is parsed
293        - bugfix: line numbers in error messages were wrong after "#include"
294        - added support for float and 32 bit sample files
295    
296      * SoundFont format engine:
297        - Initial implementation (not usable yet)

301        - initial implementation of Vibrato LFO and Modulation LFO
302        - initial implementation of cutoff filter
303        - use linear decay and release for filter and pitch EG

305      * Host plugins (VST, AU, LV2, DSSI):
306        - AU bugfix: failed to destroy its audio/MIDI devices
307        - Listen to all interfaces on Mac OS X (INADDR_ANY)
308        - VST bugfix: If the host called resume() before and after
309          changing sample rate or block size, the number of channels was
310          incorrectly set to two. This caused silence in Cubase 5.
311        - save engine type (gig, sfz or sf2) in plugin state
312        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
313          64 bit Windows
314        - AU: changed number of output channels from one stereo to 16
315          stereo
316        - VST: made it possible to build the VST plugin for Mac

318          specified
319        - LV2 "state" extension support (patch by David Robillard)
320        - VST bugfix: instrument loading hang and crashed the host when
321          the plugin was loaded a second time (#174)
322        - plugin bugfix: instrument loading hang when the plugin was
323          loaded a second time (this time it's for Linux and Mac, previous
324          similar fix was for Windows)
325        - thread safety fixes for the instrument loading thread
326        - LV2: use the new lv2 package if present
327        - VST: try to open Fantasia automatically on Linux and Mac too (on
328          Linux, the Fantasia jar should be placed in <prefix>/share/java)
329        - VST: fixed crashes on Linux Ardour and EnergyXT
330        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
331          port and audio channel routing for DSSI plugins are now visible.
332        - LV2: use urid and atom extensions instead of deprecated uri-map
333          and event
334        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
335        - LV2: changed number of output channels to 16 stereo, just like
336          the VST and AU plugins
337        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
338        - LV2: made LV2 plugin buildable on Windows and Mac

340          sampler's internal MIDI instrument mapping system
341    
342      * Instrument editor interface:
343        - Changed instrument editor plugin interface, providing additional
344          informations like the EngineChannel for which the instrument editor was
345          spawned for. This allows the instrument editors to interact more actively
346          with the sampler.
347    
348      * MIDI driver:
349        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
350          the ALSA sequencer client name

352          there is no reason for this limit
353        - MME: fixed memory handling bug found with cppcheck
354        - MME: removed compiler warning
355        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
356          which allows to retrieve the list of CoreMIDI clients / ports and to connect
357          to them a la JACK, via the usual sampler APIs
358        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
359          the driver will automatically connect to other CoreMIDI clients' ports
360          (e.g. external MIDI devices being attached to the Mac)
361        - added support for MIDI note on velocity filter
362        - CoreMIDI: fixed memory deallocation error
363        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
364          virtual keyboards in frontends / instrument editors being stuck.
365        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
366        - Implemented missing handling of MIDI "running status".
367        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
368        - MME bugfix: driver wasn't closed properly
369        - CoreMIDI: automatically connect to all input sources by default (driver
370          parameter "AUTO_BIND").
371    
372      * audio driver:
373        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
374        - JACK audio: react on sample rate changes.
375        - JACK audio: react on buffer size changes.
376        - JACK audio: jack_port_get_buffer() was cached and called outside
377          RT context.
378        - ASIO driver: removed compiler warnings
379        - CoreAudio: fixed minor error handling bug
380        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
381        - JACK audio: return the JACK server's current sample rate as default value
382          for audio device parameter "SAMPLERATE" (fixes #166).
383    
384      * LSCP server:
385        - added support for sending MIDI CC messages via LSCP command
386          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

419          "SUBSCRIBE SEND_EFFECT_CHAIN_INFO"
420        - provide comprehensive error messages on LSCP syntax errors
421          (suggesting expected next non-terminal symbols)
422    
423      * LSCP shell:
424        - Added support for auto correction of obvious and trivial syntax mistakes.

431        - Added support for moving cursor left/right with arrow keys.
432        - Added support for built-in LSCP reference documentation, which will
433          automatically show the relevant LSCP reference section on screen as soon
434          as one specific LSCP command was detected while typing on the command
435          line.
436

453          or no argument).
454        - Implemented built-in script function "set_controller()".
455        - Added extended script VM for the Gigasampler/GigaStudio format sampler
456          engine, which extends the general instrument script VM with Giga format
457          specific variables and functions.
458        - Giga format scripts: added built-in script int constant variables
459          $GIG_DIM_CHANNEL, $GIG_DIM_LAYER, $GIG_DIM_VELOCITY, $GIG_DIM_AFTERTOUCH,

483        - Pass/preserve polyphonic variable data from respective "note" event
484          handler to "release" event handler.
485    
486      * Bug fixes:
487        - Fixed crash which may occur when MIDI key + transpose is out of range
488        - minor valgrind fixes
489        - fixed crash which occurred when changing an already deployed sampler
490          channel to a different engine type
491        - fixed crash when deleting a sampler channel or changing engine
492          type while an instrument load was in progress
493        - bugfix: playing a note while changing the instrument could cause
494          a crash, or give "Handing back unknown region" error messages
495        - bugfix: calling SET VOICES (which Fantasia does on start and
496          refresh) could cause instruments to be unloaded
497        - Mac OS X: fixed name collision of enum in EffectControl and
498          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
499        - Mac OS X: fixed hanging threads
500        - Windows: disabled the previous thread fix on non-Mac systems, as
501          it caused hanging threads on Windows
502        - Fixed possible crashes due to corrupted MIDI/audio device list
503          after MIDI/audio device creation failure
504        - When creating MIDI instrument map entries with "PERSISTENT" type, the
505          instruments were uselessly precached with zero samples, however it still
506          took the full preloading time and on 1st program change the respective
507          instrument was completely reloaded again.
508        - fixed handling of rapid bank select and program change messages
509          sent to the same sampler channel (patch from the Open Octave
510          project, slightly adjusted)
511        - fixed crash when trying to create an effect instance with controls
512          which min and/or max values depend on the sample rate
513        - fixed bug #162
514        - bugfix: LADSPA_PATH was not evaluated correctly when containing
515          multiple paths (#165)

517        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
518          (#176)
519        - more thread safety fixes for the instrument loading thread
520        - sfz/sf2 engine: fixed crash when using small audio fragment size
521        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
522        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
523          introduced in previous fix)
524        - fixed crash when a channel received a program change while
525          playing a note in a key group
526        - fixed erroneous error message piping in VoiceBase.h
527          (labelled "Disk stream not available in time")
528        - Update effects on sample rate & period size changes (to avoid
529          crashes and noise on such transitions).
530        - ignore missing LADSPA paths without ignoring valid LADSPA paths
531          (fixes #208)
532        - Fixed bug in LSCP grammar definition which caused a statement like
533          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
534          practically irrelevant, however it caused problems with the new LSCP
535          shell's auto completion feature).
536        - Fixed MIDI program change messages being ignored if quickly executed
537          after each other (fixes #231).
538    
539    Version 1.0.0 (31 July 2009)
540    
541      * packaging changes:
542        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
543          causing e.g. the libgig test to fail when
544          "./configure --disable-jack-driver" was used
545          (patch by Alexis Ballier)
546        - fixed compilation with gcc 4.3
547        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
548        - fixed configure so it detects x86_64 (#107)
549        - fixes for building with newer MinGW versions
550        - fix for building with bison 2.4 (#111)
551        - fixed building with libgig installed in a non-standard directory
552        - minor fix in configure for mmsystem.h detection on MinGW
553        - Windows: look for editor plugins and Fantasia using base
554          directory of liblinuxsampler dll (look in the same directory and one
555          directory above)
556        - configure script fix: removed unconditional use of SSE
557        - fixed building with sqlite installed in a non-standard directory
558        - when cross-compiling, don't try to create instruments.db
559        - fix for new mingw-w64 version, which has usleep
560    
561      * general changes:
562        - bugfix: on some POSIX systems instrument editor plugins refused to
563          load as we used a non-portable Linux specific struct field
564          (fixes bug #70, patch by Ronald Baljeu)
565        - fixed endless loop which occured when loading an instrument editor
566          plugin DLL on Windows systems failed
567        - fixed memory leaks that occurred when liblinuxsampler was unloaded
568        - optimized the SynchronizedConfig class so it doesn't wait
569          unnecessarily long after an update
570        - added support for notifying instrument editors on note-on / note-off
571          events (e.g. to highlight the pressed keys on the virtual keyboard
572          of gigedit)
573        - added support for triggering notes by instrument editors (see above)
574        - be verbose on DLL load errors (on Linux)
575        - fixed di-harmonic triangle LFO implementation (this LFO implementation
576          is only used by very few systems, most pick the int math
577          implementation, which is usually faster)
578        - fixes for audio drivers with varying buffer sizes
579        - experimental support for running LinuxSampler as a DSSI, LV2 and
580          VST plugin
581        - notification events for stream/voice count statistics are now sent
582          only when there are actual changes
583        - added memory ordering constraints to improve stability on
584          multi-core and multi-cpu systems
585        - maximum voices and disk streams can now be altered at runtime
586        - fixed CPU feature detection on x86_64 (maybe fixes #108)
587        - automatic stacktrace mechanism is now turned off by default and can
588          be switched on by command line option "--stacktrace" (the automatic
589          stacktrace mechanism seems to be broken on most systems at the moment)
590        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
591          a pointer to the launched InstrumentEditor object
592        - added optional 3rd party user data parameter for following
593          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
594          InstrumentEditor::Launch(),
595          InstrumentManager::LaunchInstrumentEditor()
596        - theoretical fix: made SynchronizedConfig follow C++0x memory
597          model more strictly
598        - fixes for using large audio device buffers
599        - Windows: add the installation directory to the DLL search path
600          when loading an editor plugin (solves problems with VST and
601          gigedit on systems with other GTK versions installed)
602        - updated linuxsampler man page
603    
604      * audio driver:
605        - removed the nonsense audio channel constraint (which was hard coded to
606          max. 100 audio channels) for most audio drivers
607        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
608          opposed to the LSCP specs
609        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
610          reflected the wrong value
611        - fixed a memory management bug in ASIO driver
612        - Makefile fix: JACK_CFLAGS wasn't used
613        - JACK: use jack_client_open instead of the deprecated
614          jack_client_new
615        - added (experimental) CoreAudio driver
616        - applied old fixes to the ASIO driver that were included in the
617          previous binary release but accidentally never committed to CVS
618          (fixes #117)
619        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
620          win64)
621        - VST: added support for sample rate and buffer size changes
622        - VST: close editor (Fantasia) when the VST is removed
623        - VST: avoid opening Fantasia more than once for each VST instance
624        - VST: export main function as "main" on Linux too (fix for
625          energyXT)
626        - VST: changed number of output channels from one stereo to 16
627          stereo
628        - added channel routing, fxsends and midi maps to the settings
629          stored in the plugin state
630        - performance optimization of AudioChannel::MixTo() and
631          AudioChannel::CopyTo() methods using GCC vector exensions
632          (if available)
633        - ASIO fixes: avoid initializing the device twice, avoid throwing
634          exception when getting parameters from a disconnected device
635    
636      * MIDI driver:
637        - added JACK MIDI driver
638        - dispatch bank select as ordinary CC as well, the user might seriously
639          want to (mis)use it for some purpose ("fixed" in all current MIDI
640          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
641        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
642          CoreMidi or AU
643        - fixed mingw-w64 compilation error in MME driver
644        - made program change handling in MIDI thread real-time safe by
645          moving the logic to a non-RT thread
646        - fixed minor memory leak in ALSA driver
647    
648      * instruments database:
649        - avoid time consuming samples scanning when adding instruments
650          to the instruments database
651        - added support for handling lost files in the instruments database
652        - Implemented option for adding instruments in separate directories
653          in the instruments database
654          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
655        - work-around for missing fnmatch function on Windows to make
656          instrument database compilable
657        - added instrument database support on Windows
658          works with both standalone mode and VST plugin.
659          the instruments DB file is located in
660          %USERPROFILE%\.linuxsampler\instruments.db which allows different
661          databases for each windows user
662          if no DB is present it automatically creates the .linuxsampler subdir
663          and then creates an empty DB
664        - fixed recursive import, which was broken on Windows
665    
666      * Gigasampler format engine:
667        - fixed a memory leak that could happen when a channel was deleted
668          while notes were playing
669        - made it possible to load an instrument even if the audio thread
670          isn't running
671        - added partial support for the "Controller Triggered" MIDI rule,
672          enough for piano gigs with pedal noise samples
673        - minor fix: only mark FX sends as being modified if really the
674          respective FX send MIDI controller was used
675        - added support for GM global device volume SysEx message
676          (can be selected at compile time to either apply globally to the
677          whole sampler [default] or only to the sampler channels that are
678          connected to the respective MIDI input port the SysEx message arrived
679          on)
680        - bugfix: notes triggered at position 0 in the audio buffer were
681          sometimes wrongly killed in the same buffer, causing no sound to
682          be played
683        - added support for chromatic / drumkit mode Roland GS Sysex message
684          which is usally used to switch a part between chromatic sounds and
685          drumkit sounds (as opposed to their common default setting of MIDI
686          part 10 being a drumkit part and all other ones chromatic parts), in
687          LS however one can switch between the first 16 MIDI instrument maps
688          defined for the sampler
689        - made it possible to create multiple sample channels even if the
690          audio thread isn't running
691        - fixed crash when removing channel with active voices (#116)
692        - bugfix: on sample reference changes (instrument editor), only
693          un-cache the respective sample if it's really not used by any
694          sampler engine anymore
695        - re-cache samples in case they were changed by an instrument editor,
696          e.g. when a sample was added while playing (#82)
697        - fixed hanging notes which occured when note-off event had the exact
698          same time stamp as the voice's note-on event and occured both in the
699          same audio fragment cycle (fixes bug #112)
700        - added support for the "fine tune" and "pitch bend range"
701          instrument-level gig parameters
702        - fixed minor artifacts in pitch bend handling
703        - added support for GS Reset SysEx message
704        - allow gig files to use unlimited downward pitch shifting
705        - added a limit check for upward pitch shifting

708        - fixed crash happening when a pitch bend event arrived at the
709          same time a new instrument was loading
710    
711      * LSCP server:
712        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
713          react on MIDI data arriving on certain sampler channels (so far only
714          Note-On and Note-Off events are sent via this LSCP event)
715        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
716          react on MIDI data arriving on certain MIDI input devices (so far only
717          Note-On and Note-Off events are sent via this LSCP event)
718        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
719          SET DB_INSTRUMENT FILE_PATH
720        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by

722        - added two additional fields to GET FILE INSTRUMENT INFO command -
723          KEY_BINDINGS and KEYSWITCH_BINDINGS
724        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
725          was incorrect
726        - Optimized the retrieval of the MIDI instrument mappings
727        - added new LSCP command "SET VOICES" to globally alter the maximum
728          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
729          be triggered respectively
730        - added new LSCP command "SET STREAMS" to globally alter the maximum
731          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
732          which will be triggered respectively
733        - bugfix: retry if "select" returns EINTR (this fixes a crash when
734          a gigedit file dialog is opened)
735        - close all connections when LSCPServer is deleted
736        - hard close of all sockets on exit
737        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
738          driver
739    
740      * Bug fixes:
741        - fixed a crash which occurs when removing a sampler channel waiting
742          to start instrument loading after another channel
743        - fixed a crash which occurs when removing a sampler channel with
744          instrument loading in progress (bug #113)
745        - fixed termination caused by uncaught exception when adding MIDI
746          instrument with PERSISTENT load mode
747        - fixed possible iterator invalidations when resetting the sampler
748        - fixed memory leaks when issuing the following LSCP commands:
749          GET AUDIO_OUTPUT_DRIVER INFO
750          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
751          GET MIDI_INPUT_DRIVER INFO
752          GET MIDI_INPUT_DRIVER_PARAMETER INFO
753        - fixed possible compilation error when sqlite is not present
754        - fixed orphaned pointers when setting maximum voices limit (bug #118)
755        - fixed crash when changing the audio output device of a sampler
756          channel with loaded instrument and start playing notes
757        - fixed endless loop in Engine::SuspendAll() (bug #120)
758        - fixed a low-level atomic load function that was broken on 64-bit
759          PowerPC, which probably could cause crashes on that platform
760        - fixed a memory management error which could cause a crash when a
761          plugin was unloaded
762        - bugfix: two private structs had the same name, which could cause
763          problems if the linker chose the wrong constructor
764        - fixed low-level ConditionServer usage bug that caused lockups on
765          Windows
