* NKSP: Adjusted behavior of "change_vol()" and "change_tune()" to a more
  intuitive behavior if used in combination with "change_vol_time()" or
  "change_tune_time()" respectively: now tuning/volume changes are only
  assigned (without delay) immediately to a new note if the respective
  timing function has not been called before, otherwise the volume/tuning
  changes are automatically faded (before, only the event's time stamp was
  relevant).
* Bumped version (2.0.0.svn50).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
6     - Added support for sfz extension opcode 'script' which may be used to
7     load real-time instrument script file (NKSP script language).
8 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
10 persson 2856
11 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
12 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13     cutoff settings.
14    
15 persson 2837 * general changes:
16     - fixed printf type errors (mostly in debug messages)
17 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
18 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19     allowing to sort data efficiently in real-time safe manner.
20     - RTList class: added methods for moving/inserting elements to arbitrary
21     position within a list.
22     - RTList class: added method fromPtr() for creating an Iterator object from
23     a raw element pointer.
24     - Attempt to partly fix resetting engine channels vs. resetting engine, an
25     overall cleanup of the Reset*(), ConnectAudioDevice(),
26     DisconnectAudioDevice() API methods would still be desirable though,
27     because the current situation is still inconsistent and error prone.
28 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
29     being directly assigned to a keyboard key. This allows more fine graded
30     processing of voices, which is i.e. required for certain instrument
31     script features.
32 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
33     (CC #64) events.
34     - Fix: Release trigger voices can now also distinguish correctly between
35     note-off and sustain pedal up events.
36 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
37     (while slow rate of crossfade smoother is preserved) to allow quick
38     volume and pan changes by instrument scripts for instance.
39 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40     properly and thus were ignored for certain uses.
41 schoenebeck 3018 - Added new C++ API method
42     VirtualMidiDevice::SendChannelPressureToSampler().
43 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
44     sub threads is 16-byte aligned
45 schoenebeck 3054 - fixed numerous compiler warnings
46 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
47 persson 2837
48 schoenebeck 2866 * packaging changes:
49     - removed unnecessary dependency to libuuid
50     (originated by libgig's usage of it)
51 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
52     auto detect whether it (sh/c)ould output its messages in color.
53 schoenebeck 2866
54 schoenebeck 2871 * Real-time instrument scripts:
55     - Implemented scheduler for delayed MIDI events and for suspended scripts.
56     - Built-in script function "wait()": implemented support for function's
57     "duration-us" argument, thus scripts using this function are now
58     correctly resumed after the requested amount of microseconds.
59     - Built-in script function "play_note()": implemented support for
60     function's "duration-us" argument, thus notes triggered with this
61     argument are now correctly released after the requested amount of
62     microseconds.
63     - Fix: script events were not cleared when engine channel was reset,
64     potentially causing undefined behavior.
65     - Fixed crash which happened when trying to reference an undeclared
66     variable.
67 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
68     special value -1 for "duration-us" argument, which will cause the
69     triggered note to be released once the original note was released.
70 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
71     - Added new API method ScriptVM::syntaxHighlighting() which provides
72     a convenient syntax highlighting backend for external instrument
73     script editor applications.
74 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
75     - Extended parser issues to provide not only first line and first
76     column, but also last line and last column of issue (thus marking
77     the precise span of the issue within the source code).
78 schoenebeck 2902 - Reload script automatically after being modified by an instrument
79     editor.
80 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
81     like "on note end on".
82 schoenebeck 2931 - Implemented built-in script function "change_vol()".
83     - Implemented built-in script function "change_tune()".
84     - Implemented built-in script function "change_pan()".

86     - Implemented built-in script function "change_reso()".
87     - Implemented built-in script function "event_status()".
88     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
89     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
90     "event_status()" function.
91     - NKSP language: Added support for bitwise operators ".or.", ".and."
92     and ".not.".
93     - NKSP language scanner: Fixed IDs matching to require at least one
94     character (i.e. when matching function names or variable names).
95     - NKSP language scanner: disabled unusued rules.
96 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
97     be distinguished engine internally from "real" MIDI note on/off
98     events in order to avoid misbehaviors like hanging notes.
99 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
100     - Implemented built-in script variable "$NKSP_REAL_TIMER".
101     - Implemented built-in script variable "$NKSP_PERF_TIMER".
102     - Implemented built-in script variable "$ENGINE_UPTIME".
103 schoenebeck 2945 - Implemented built-in script function "inc()".
104     - Implemented built-in script function "dec()".
105     - NKSP language fix: division expressions were evaluated too often.
106     - NKSP language fix: string concatenation operator was right
107     associative instead of left (to right).
108 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
109     (i.e. "if end if").
110 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
111     - Implemented built-in script variable "$NI_CALLBACK_ID".
112     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
113     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
114     - Added support for read-only built-in variables (respectively
115     handled by the script parser).
116     - Added built-in script constant "$NI_CB_TYPE_INIT".
117     - Added built-in script constant "$NI_CB_TYPE_NOTE".
118     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
120 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
121 schoenebeck 2953 - Implemented built-in script function "change_attack()".
122     - Implemented built-in script function "change_decay()".
123     - Implemented built-in script function "change_release()".
124 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
125     synthesis parameter changes immediately in case the respective note
126     was triggered at the same time, instead of scheduling the parameter
127     change, especially because it would cause some parameter types's
128     changes either to be ramped (i.e. change_vol()) or other types even
129     to have not effect at all (i.e. change_attack()).
130 schoenebeck 2965 - Implemented built-in script function "sh_left()".
131     - Implemented built-in script function "sh_right()".
132 schoenebeck 2970 - Implemented built-in script function "min()".
133     - Implemented built-in script function "max()".
134 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
135     was loaded.
136     - NKSP built-in wait() script function: abort script execution if
137     a negative or zero wait time was passed as argument (since this is
138     a common indication of a bug either of the script or even of the
139     engine, which could lead to RT instability or even worse).
140 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
141     threatening scripts.
142 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
143 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
144     initializer list to an array variable.
145 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
146 schoenebeck 3076 - Implemented built-in script function "in_range()".
147 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".
148     - Implemented built-in script function "change_amp_lfo_freq()".
149     - Implemented built-in script function "change_pitch_lfo_depth()".
150     - Implemented built-in script function "change_pitch_lfo_freq()".
151 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
152     - Implemented built-in script function "change_tune_time()".
153     - Implemented built-in script function "fade_in()".
154     - Implemented built-in script function "fade_out()".
155     - Fixed acceptance of wrong data type of parameters passed to built-in
156     script functions "change_vol()", "change_tune()", "change_pan()",
157     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
161     of its possible parameter selections.
162     - Added built-in script function "set_event_par()" and implemented some
163     of its possible parameter selections.
164 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
165 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
166 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
167     built-in function "ignore_controller()".
168 schoenebeck 3214 - Implemented built-in script function "change_velo()".
169     - Implemented built-in script function "change_note()".
170 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171     intuitive behavior if used in combination with "change_vol_time()" or
172     "change_tune_time()" respectively: now tuning/volume changes are only
173     assigned (without delay) immediately to a new note if the respective
174     timing function has not been called before, otherwise the volume/tuning
175     changes are automatically faded (before, only the event's time stamp was
176     relevant).
177 schoenebeck 2871
178 schoenebeck 3050 * Instruments DB:
179     - Fixed memory access bug of general DB access code which lead to
180     undefined behavior.
181 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
182     - The instrument DB path of linuxsampler's --create-instruments-db argument
183     is now optional, if it is missing, then a default location is used.
184 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
185     - Added support for scanning Sound Font (.sf2) files.
186 schoenebeck 3101 - Fixed undefined DB transaction behavior.
187 schoenebeck 3050

199 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
200 persson 2197 - minor Makefile fix for building lscpparser when build and source
201     directories are separate
202 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to

226     in order to get rid of warnings from automake 1.14
227 persson 2382
228 persson 2086 * general changes:
229 iliev 2012 - Refactoring: moved the independent code from
230     the Gigasampler format engine to base classes
231 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
232     respective profiling code is currently broken
233 schoenebeck 2053 - Introduced support for optional environment variable
234     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
235     where the sampler shall look for instrument editor plugins
236     (patch by Luis Garrido, slightly modified).
237 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
238     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
239     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
240     note (in this implementation of the sampler its simply hard routed to
241     the 1st effect send of the sampler channel, no matter what the actual
242     effect type is)
243     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
244     note (in this implementation of the sampler its simply hard routed to
245     the 2nd effect send of the sampler channel, no matter what the actual
246     effect type is)
247 schoenebeck 2124 - implemented support for internal LADSPA effects
248 schoenebeck 2140 - raised limit of program change queue from 100 to 512
249     (as suggested by Alex Stone)
250 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
251 iliev 2296 - experimental support for per voice equalization
252 iliev 2306 - added command line option --exec-after-init
253 schoenebeck 2330 - Introduced new C++ API method:
254     EngineChannel::InstrumentFileName(int index)
255     allowing to retrieve the whole list of files used for the loaded
256     instrument on an engine channel (a.k.a. part). Some GigaStudio
257     instruments for example are splitted over several files like
258     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
259 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
260     - Added new C++ API method Sampler::GetGlobalMaxStreams().
261     - Added new C++ API method Sampler::SetGlobalMaxVoices().
262     - Added new C++ API method Sampler::SetGlobalMaxStreams().
263 schoenebeck 2377 - Various "const" and "restrict" optimizations.
264 persson 2382 - all engines: add pan CC value to instrument pan parameter before
265     applying panning, instead of using two separate pan functions in
266     series (#182)
267 persson 2427 - added a lock guard class for exception safe mutex handling and
268     used it everywhere appropriate
269 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
270     - Exposed scale tuning to C++ API (along to the already existing standard
271     SysEx way).
272 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
273     and broken for ppc64. (Seq_cst loads and stores are actually not
274     used in LS, so the bug wasn't noticable.)
275     - lsatomic.h: added ARMv7 support
276 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
277     added various new C++ methods for this new feature / design change, old
278     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
279     as deprecated but are still there and should provide full behavior
280     backward compatibility).
281     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
282     unsafe and caused compilation error with clang 2.x).
283 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
284 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
285     sampler from the command line by providing LSCP aware features.
286 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
287     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
288     - VirtualMidiDevice: Added support for pitch bend.
289 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
290     polyphonic key pressure events (so far polyphonic pressure was not
291     supported at all, and channel pressure was rerouted as CC128 but not
292     used so far).
293 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
294     code is shared by all sampler engine implemementations, however only the
295     gig file format currently provides support for storing instrument scripts
296     (as LinuxSampler extension to the original GigaStudio 4 format).
297 iliev 2012
298 persson 2043 * Gigasampler format engine:
299     - implemented the "round robin keyboard" dimension
300     - fixed round robin and random dimensions for cases when number of
301     dimension zones is not a power of two
302     - made round robin use a counter for each region instead of each
303     key
304 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
305     - bugfix: filter keyboard tracking was broken
306     - filter performance fix (an unnecessary copy was made of the
307     filter parameters in each sub fragment)
308     - handle special case when pan parameter in gig file has max or
309     min value
310 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
311     doesn't sound naturally with a drumkit
312 persson 2408 - fixed EG1 modulation when attack or release is zero
313 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
314 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
315     conditions (see also previous commit on libgig).
316 persson 2673 - fixed behaviour of filter LFO
317 persson 2043
318 schoenebeck 2047 * SFZ format engine:

336     - fine-tuned the default velocity curve
337 persson 2086 - added support for transpose
338     - fixed crash when using sw_down/up
339     - improved logic for sw_lokey/hikey/up/down/last
340     - added more v1 aliases to parser
341 persson 2091 - reduced memory usage for sfz data

689     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
690 persson 2185 - Mac OS X: fixed hanging threads
691 persson 2187 - Windows: disabled the previous thread fix on non-Mac systems, as
692     it caused hanging threads on Windows
693 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
694     after MIDI/audio device creation failure
695 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
696     instruments were uselessly precached with zero samples, however it still
697     took the full preloading time and on 1st program change the respective
698     instrument was completely reloaded again.
699 persson 2277 - fixed handling of rapid bank select and program change messages
700     sent to the same sampler channel (patch from the Open Octave
701     project, slightly adjusted)

706     multiple paths (#165)
707 persson 2324 - thread safety fixes for the instrument loading thread
708 persson 2326 - bugfix: instrument loading crashed for sfz and sf2 in Ardour

718     (labelled "Disk stream not available in time")
719 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
720     crashes and noise on such transitions).
721 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
722     (fixes #208)
723 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
724     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
725     practically irrelevant, however it caused problems with the new LSCP
726     shell's auto completion feature).
727 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
728     after each other (fixes #231).

731 schoenebeck 1599
732 schoenebeck 1639 * packaging changes:
733     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

765 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
766 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

777 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
778 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
779     be switched on by command line option "--stacktrace" (the automatic
780     stacktrace mechanism seems to be broken on most systems at the moment)
781 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
782     a pointer to the launched InstrumentEditor object
783 schoenebeck 1876 - added optional 3rd party user data parameter for following
784     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

788     model more strictly
789 persson 1895 - fixes for using large audio device buffers
790 persson 1951 - Windows: add the installation directory to the DLL search path

801     reflected the wrong value
802 persson 1644 - fixed a memory management bug in ASIO driver
803 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

805 persson 1748 jack_client_new
806 iliev 1829 - added (experimental) CoreAudio driver
807 persson 1888 - applied old fixes to the ASIO driver that were included in the
808     previous binary release but accidentally never committed to CVS
809     (fixes #117)
810 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
811     win64)
812 persson 1895 - VST: added support for sample rate and buffer size changes
813     - VST: close editor (Fantasia) when the VST is removed

820     stored in the plugin state
821 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
822     AudioChannel::CopyTo() methods using GCC vector exensions
823     (if available)
824 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
825     exception when getting parameters from a disconnected device
826 schoenebeck 1599
827 persson 1651 * MIDI driver:
828     - added JACK MIDI driver
829 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
830     want to (mis)use it for some purpose ("fixed" in all current MIDI
831     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
832 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
833 persson 1887 CoreMidi or AU
834 persson 1889 - fixed mingw-w64 compilation error in MME driver
835 persson 1924 - made program change handling in MIDI thread real-time safe by
836     moving the logic to a non-RT thread
837 persson 1951 - fixed minor memory leak in ALSA driver
838 persson 1651

844     in the instruments database
845     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
846 persson 1908 - work-around for missing fnmatch function on Windows to make
847     instrument database compilable
848 schoenebeck 1930 - added instrument database support on Windows
849     works with both standalone mode and VST plugin.
850     the instruments DB file is located in
851     %USERPROFILE%\.linuxsampler\instruments.db which allows different
852     databases for each windows user
853     if no DB is present it automatically creates the .linuxsampler subdir
854     and then creates an empty DB
855 persson 1943 - fixed recursive import, which was broken on Windows
856 iliev 1603
857 persson 1644 * Gigasampler format engine:
858     - fixed a memory leak that could happen when a channel was deleted
859     while notes were playing
860 persson 1646 - made it possible to load an instrument even if the audio thread
861     isn't running
862 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
863     enough for piano gigs with pedal noise samples
864 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
865     respective FX send MIDI controller was used
866 schoenebeck 1724 - added support for GM global device volume SysEx message
867 schoenebeck 1762 (can be selected at compile time to either apply globally to the
868     whole sampler [default] or only to the sampler channels that are
869     connected to the respective MIDI input port the SysEx message arrived
870     on)
871 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
872     sometimes wrongly killed in the same buffer, causing no sound to
873     be played
874 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
875     which is usally used to switch a part between chromatic sounds and
876     drumkit sounds (as opposed to their common default setting of MIDI
877     part 10 being a drumkit part and all other ones chromatic parts), in
878     LS however one can switch between the first 16 MIDI instrument maps
879     defined for the sampler
880 persson 1764 - made it possible to create multiple sample channels even if the
881     audio thread isn't running
882 persson 1844 - fixed crash when removing channel with active voices (#116)
883 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
884     un-cache the respective sample if it's really not used by any
885     sampler engine anymore
886     - re-cache samples in case they were changed by an instrument editor,
887     e.g. when a sample was added while playing (#82)
888 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
889     same time stamp as the voice's note-on event and occured both in the
890     same audio fragment cycle (fixes bug #112)
891 persson 1858 - added support for the "fine tune" and "pitch bend range"
892     instrument-level gig parameters
893     - fixed minor artifacts in pitch bend handling
894 schoenebeck 1860 - added support for GS Reset SysEx message
895 persson 1862 - allow gig files to use unlimited downward pitch shifting
896     - added a limit check for upward pitch shifting
897 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
898     note was silent
899 persson 1923 - fixed crash happening when a pitch bend event arrived at the
900     same time a new instrument was loading
901 persson 1644
902 schoenebeck 1687 * LSCP server:
903     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
904     react on MIDI data arriving on certain sampler channels (so far only
905     Note-On and Note-Off events are sent via this LSCP event)
906 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
907     react on MIDI data arriving on certain MIDI input devices (so far only
908     Note-On and Note-Off events are sent via this LSCP event)
909 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
910     SET DB_INSTRUMENT FILE_PATH
911 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
912     frontends to send MIDI messages to specific sampler channel
913     - added two additional fields to GET FILE INSTRUMENT INFO command -
914     KEY_BINDINGS and KEYSWITCH_BINDINGS
915 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
916     was incorrect
917 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
918 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
919     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
920     be triggered respectively
921     - added new LSCP command "SET STREAMS" to globally alter the maximum
922     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
923     which will be triggered respectively
924 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
925     a gigedit file dialog is opened)
926 iliev 1848 - close all connections when LSCPServer is deleted
927 iliev 1882 - hard close of all sockets on exit
928 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
929     driver
930 schoenebeck 1687
931 iliev 1761 * Bug fixes:
932     - fixed a crash which occurs when removing a sampler channel waiting
933     to start instrument loading after another channel
934 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
935     instrument loading in progress (bug #113)
936 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
937     instrument with PERSISTENT load mode
938 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
939     - fixed memory leaks when issuing the following LSCP commands:
940     GET AUDIO_OUTPUT_DRIVER INFO
941     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
942     GET MIDI_INPUT_DRIVER INFO
943     GET MIDI_INPUT_DRIVER_PARAMETER INFO
944     - fixed possible compilation error when sqlite is not present
945 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
946 iliev 1847 - fixed crash when changing the audio output device of a sampler
947     channel with loaded instrument and start playing notes
948 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
949 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
950     PowerPC, which probably could cause crashes on that platform
951 persson 1889 - fixed a memory management error which could cause a crash when a
952     plugin was unloaded
953 persson 1896 - bugfix: two private structs had the same name, which could cause
954     problems if the linker chose the wrong constructor
955 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
956     Windows
957 iliev 1761
958    
959 schoenebeck 1560 Version 0.5.1 (6 December 2007)
960 schoenebeck 1454
961     * packaging changes:
962     - added autoconf checks for pthread library
963     - added autoconf check for pthread bug found on certain NPTL-enabled
964     glibc versions (see Gentoo bug report #194076)
965 senoner 1502 - added autoconf checks for MS Windows
966 schoenebeck 1454
967 persson 1455 * general changes:
968     - bugfix: the thread used by an editor plugin didn't die when the
969     editor closed
970 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
971     out all the space. operator--() did not apply size_mask after
972     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
973     order to avoid problems with the _NonVolatileReader functions.
974     - bugfix: Stream.h: added a missing divide by BytesPerSample in
975     GetWriteSpace(). Since this function is currently only used in
976     the stream's qsort() compare function, it didn't trigger any
977     bugs.
978     - Resampler.h, Synthesizer.h: cubic interpolation now works in
979     24bit mode too. Faster method to read 24bit words on little
980     endian machines (x86): replaced 3 byte reads + shifts with a 1
981     unaligned 32bit read and shift
982     - experimental support for MS Windows (MIDI input via MME, AUDIO
983     output via ASIO)
984     - made handling of SIGINT signal (Ctrl-C) a bit more robust
985 iliev 1541 - support for monitoring the total number of active disk streams
986     (new LSCP commands: GET TOTAL_STREAM_COUNT,
987     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
988 persson 1455
989 senoner 1500 * AUDIO driver:
990 persson 1534 - added Windows ASIO low latency audio driver
991 senoner 1500
992 senoner 1485 * MIDI driver:
993 schoenebeck 1495 - added MME Windows MIDI driver
994 senoner 1485
995 schoenebeck 1471 * LSCP server:
996     - added support for Windows style path / filenames, however with
997     forward slash path separators instead of backslash
998     (i.e. "C:/foo/bar.gig")
999 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1000     apostrophes as well
1001 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1002     "LIST FILE INSTRUMENTS <file>" and
1003     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1004     about an arbitrary instrument file on the system where the sampler is
1005     running on
1006 schoenebeck 1471
1007 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1008 schoenebeck 947
1009 schoenebeck 1065 * packaging changes:
1010 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1011     API header files anymore
1012 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1013     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1014 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1015     capable to execute our autoconf environment, thus no need anymore
1016     to maintain the compile time configuration file (osx/version.h) for
1017     OSX manually (patch by Toshi Nagata)
1018 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1019     parameters
1020 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1021     C++ API header files, all implementation internal global definitions
1022     are now in global_private.h
1023     - atomic.h is not exposed to the C++ API anymore
1024     - no need to include config.h anymore for using LS's API header files
1025     - fixed warnings in API doc generation
1026 schoenebeck 1065
1027 schoenebeck 947 * general changes:
1028     - replaced the old, confusing MIDI program change mechanism by a
1029     flexible MIDI instrument mapper which allows to map arbitrary
1030 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1031 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1032     loaded on the respective channel when such MIDI program change
1033     messages arrive, beside that, each entry allows to define a life-time
1034     strategy for the instrument, so the user can define whether the
1035     instrument should i.e. be permanently loaded (to be able to switch
1036     quickly among sounds) or i.e. loaded just on demand when the
1037     respective program change arrives (to safe RAM space), as well as a
1038     global volume factor for each entry, so the user can adjust the volume
1039     dynamic of his mapped instrument collection without having to modify
1040 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1041     MIDI instrument maps and assign each sampler channel individually
1042     a certain map, so that i.e. separation of normal instruments and
1043     drumkits is possible
1044 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1045     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1046 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1047     due to a constant size RingBuffer FIFO which is now replaced by a
1048     dynamic (unlimited) size std::list FIFO
1049 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1050     output channels for being processed by external effect processors
1051     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1052     controllers
1053 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1054 iliev 1130 - Implemented new, improved notification system
1055 schoenebeck 1149 - fixed compilation errors regarding OSX
1056     (patch by Toshi Nagata)
1057 iliev 1161 - implemented instruments database
1058 iliev 1345 - added support for escape sequences to the instruments database
1059 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1060     within the sampler's process (by using instrument editor plugins),
1061     you'll notice the new "Registered instrument editors:" message on
1062 schoenebeck 1407 startup, added a new LSCP command:
1063     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1064 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1065     given sampler channel, the plugin path can be overridden at compile
1066     time with ./configure --enable-plugin-dir=/some/dir
1067 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1068     in the sampler's process to safely edit instruments while playing
1069     without a crash (hopefully) by either suspending single regions
1070     wherever possible or if unavoidable whole engine(s)
1071 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1072     policy and priority on thread level, set a minimum stack size for
1073     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1074     threads simply inherited properties of starting thread instead of
1075     setting their own policy and priority
1076 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1077     main process did not wait for the stack trace process to finish
1078     its output
1079 persson 1248 - fixed some minor memory leaks
1080 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1081     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1082 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1083     register, to avoid relocations in the text segment at runtime)
1084 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1085 schoenebeck 947
1086     * MIDI driver:
1087     - dispatch bank select (MSB and LSB) messages
1088    
1089 schoenebeck 1049 * audio driver:
1090     - the ALSA audio output driver parameters now reflect the correct
1091     parameter value ranges for the respective selected sound card
1092     (patch by Till Wimmer, a bit fixed and extended)
1093    
1094 persson 951 * Gigasampler format engine:
1095     - if a filter is used and EG2 finishes before EG1, let the voice
1096     die when EG2 has finished (this fixes a problem with clicks and
1097     voice starvation for some gigs)
1098 persson 1038 - playback is no longer disabled during instrument loading
1099     - all notes playing on a channel that changes its instrument keep
1100     playing with the old instrument until they get a note off
1101     command
1102 persson 1039 - EG fix: a release value of zero could cause noises or crash
1103 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1104 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1105     above max sustain level, which means that there is a decay phase
1106     even if sustain is 100%
1107 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1108     noises or crashes
1109 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1110 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1111     supplied to the configure script (fixes #46)
1112 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1113     instead of a fix value
1114 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1115     127 (solo mode) only kill voices if the respective mode really
1116     changed
1117 persson 951
1118 schoenebeck 1244 * LSCP server:
1119     - fixed compile time error for old Bison versions
1120     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1121 schoenebeck 1245 - parser now supports extended ASCII character set
1122     (up to ASCII code 255, i.e. includes now umlauts and accents)
1123     - filename arguments in LSCP commands now allow to use escape
1124     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1125     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1126     code value like \xf2) (fixes bug #24)
1127 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1128     least one of their text-based parameters (i.e. name, description):
1129     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1130     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1131     "SET DB_INSTRUMENT_DIRECTORY NAME",
1132     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1133     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1134     "FIND DB_INSTRUMENT_DIRECTORIES"
1135 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1136     occured, the unexpected character and the actually expected, possible
1137     character(s), the latter only if less than 5 possibilities)
1138 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1139     settings
1140 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1141     of strings were treated as being one string containing commas
1142     (fixes #57)
1143 schoenebeck 1244
1144 iliev 959 * Bug fixes:
1145     - fixed crash occurring on certain LSCP scripts (Bug 39)
1146 persson 1038 - another thread safety fix for lscp "load engine" and "set
1147     channel audio output device"
1148 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1149     on a sampler channel with connected MIDI device
1150 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1151     device connected to a sampler channel to number less then or equal
1152     to the index of the port to which the sampler channel is connected.
1153 iliev 1296 - The previous bindings were not been disconnected when altering
1154     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1155     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1156 iliev 1297 - The active stream/voice count statistic was incorrect.
1157 iliev 1298 - notification events were not been sent for some sampler
1158     channel changes
1159 iliev 1305 - added default min and max values to restrict the number of allowed
1160     audio output channels and MIDI input ports
1161 iliev 1306 - the connection to the PCM interface is now closed when destroying
1162     an audio output device
1163 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1164 iliev 959
1165 schoenebeck 1221 * test cases:
1166     - updated and fixed (haven't been touched in a while)
1167    
1168 schoenebeck 937 Version 0.4.0 (24 November 2006)
1169 persson 696
1170 schoenebeck 697 * packaging changes:
1171 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1172     to post-(un)install steps; added devel package for liblinuxsampler;
1173     to linuxsampler.spec (RPM)
1174 schoenebeck 697 - install necessary development header files for allowing 3rd party
1175     applications to link against liblinuxsampler
1176     - liblinuxsampler's API documentation can be generated with 'make docs'
1177     (Doxygen required)
1178 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1179     implementation (currently either an integer math solution or a
1180     di-harmonic approximation), automatic detection can be overriden
1181     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1182     configure script argument though (mandatory for cross-compilation)
1183 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1184     provided some on his own (as CXXFLAGS)
1185 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1186     messages
1187 schoenebeck 852 - added compile time options to allow disabling the various audio and
1188     MIDI drivers
1189 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1190     (patch by Ebrahim Mayat)
1191 schoenebeck 697
1192 persson 696 * Gigasampler format engine:
1193 schoenebeck 738 - extensive synthesis optimization
1194     (reimplementation of EGs and LFO(s), removed synthesis parameter
1195     prerendering and the synthesis parameter matrix in general, splitting
1196     each audio fragment into subfragments now where each subfragment uses
1197 persson 830 constant pitch and filter coefficients. The volume coefficient is
1198     linearly interpolated inside a subfragment, unless
1199     --disable-interpolate-volume is set.)
1200 persson 696 - fine tuning of the EG modulation parameters
1201 persson 729 - improved filter cutoff calculation by adding support for the
1202     following gig parameters: Cutoff freq (used when no cutoff
1203     controller is defined), Control invert, Minimum cutoff, Velocity
1204 persson 791 curve and Velocity range. The keyboard tracking now scales
1205     cutoff frequency instead of resonance.
1206 persson 877 - added support for gig parameter Resonance.
1207 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1208 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1209     which can be overridden with --enable-global-attenuation
1210 persson 783 - EG fixes: made the length of "attack hold" stage more
1211     accurate. Release stage can now start before attack stage
1212 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1213     time now has a minimal value to prevent clicks.
1214 persson 799 - fixed pitch changes larger than one octave
1215 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1216     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1217     all modes can be altered via standard GM messages, that is CC5 for
1218     altering portamento time, CC65 for enabling / disabling portamento
1219     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1220 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1221     parameter) and crossfade
1222 persson 831 - added support for the "attenuation controller threshold" gig
1223     parameter
1224 persson 832 - added smoothing of volume changes caused by control change
1225     messages
1226 persson 865 - sample loop parameters are now taken from the DimensionRegion
1227     instead of the wave chunk
1228     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1229     not equal to a power of two
1230 persson 877 - reimplementation of the filter algorithm. The new filter is more
1231     accurate and supports all gig filter types, including bandreject
1232     and lowpass turbo.
1233 persson 903 - real support for 24 bit samples - samples are not truncated to
1234     16 bits anymore
1235     - support for aftertouch (channel pressure, not polyphonic
1236     aftertouch)
1237 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1238     amplifying from 0)
1239 persson 696
1240 schoenebeck 711 * LSCP server:
1241     - fixed application exit on broken pipe error (fixes bug #20)
1242 iliev 793 - fixed the notification messages delay due to lack of
1243     network activity (fixes bug #26)
1244 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1245     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1246 schoenebeck 711
1247 schoenebeck 838 * audio driver:
1248     - added aRts audio output driver (by no means RT safe)
1249    
1250 schoenebeck 775 * MIDI driver:
1251     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1252     messages several times instead of once
1253 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1254     for events (i.e. for offline rendering based MIDI drivers)
1255 persson 922 - added checks for bad MIDI data
1256 schoenebeck 775
1257 schoenebeck 900 * linuxsampler application:
1258     - show available sampler engine types on startup
1259    
1260 schoenebeck 705 * general changes:
1261     - support for muting sampler channels and solo mode of the same, two new
1262     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1263     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1264     introduced for this, the behavior is the same like on a mixer console
1265 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1266     --enable-process-muted-channels which can be used to enable the
1267     processing of muted channels.
1268 iliev 777 - support for sostenuto pedal
1269 iliev 779 - support for monitoring the total number of active voices
1270 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1271     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1272 persson 835 - fixed some memory management errors
1273 persson 841 - fixed some concurrency problems that could lead to crashes when
1274     LSCP commands were executed
1275 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1276     sampler channel (fixes bug #36)
1277 schoenebeck 705
1278 schoenebeck 692 Version 0.3.3 (15 July 2005)
1279 schoenebeck 686
1280     * packaging changes:
1281     - fixed compilation with gcc 4.0
1282    
1283 schoenebeck 687 * Gigasampler format engine:
1284     - LFO preprocessing was performed even though the respective LFO was
1285     disabled by the instrument patch (minor efficiency fix)
1286 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1287     for volume ramp downs in the same fragment (needed for current voice
1288     stealing implementation) then simply inform the user with a warning
1289     about possible click sounds and reduce the volume ramp down
1290     appropriately instead of cancelling the audio device connection
1291 schoenebeck 687
1292 schoenebeck 677 Version 0.3.2 (24 June 2005)
1293 schoenebeck 609
1294     * packaging changes:
1295     - updated autotools build files to compile on OS X
1296     (conditional compilation of CoreMIDI and MidiShare drivers)
1297 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1298     './configure --disable-asm' (definitely not recommended)
1299 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1300     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1301     (due to 'dist-bzip2' automake option)
1302 schoenebeck 649
1303     * Gigasampler format engine:
1304     - support for the gig parameters for "release velocity response" curves
1305     - fine tuning of the EGADSR envelope
1306     - volume of release triggered samples now depends on note-on velocity,
1307     note length and gig parameter "release trigger decay" instead of
1308     note-off velocity.
1309 schoenebeck 663 - revised voice stealing
1310     (fixes crash and endless loop caused by voice stealing)
1311 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1312 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1313     instead of when the respective voice is actually launched
1314     (fixes undefined behavior if stolen voices belonged to a key group -
1315     this case was followed by a "killed voice survived" error message)
1316 schoenebeck 669 - fixed minor issue with null/silence samples
1317     (those stole voices even though they don't need a voice at all which
1318     resulted in "voice stealing didn't work out" messages)
1319 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1320     instrument or audio output device change
1321 schoenebeck 654
1322 schoenebeck 620 * LSCP server:
1323 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1324 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1325 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1326 schoenebeck 609
1327 schoenebeck 668 * linuxsampler application:
1328     - added command line parameters --lscp-addr and --lscp-port to override
1329     default IP address and port of LSCP server
1330    
1331 schoenebeck 579 Version 0.3.1 (24 May 2005)
1332    
1333     * initial release
