File size: 69675 byte(s)
* Instruments DB: Added support for scanning SFZ (.sfz) files.
* Instruments DB: Added support for scanning Sound Font (.sf2) files.
* Bumped version (2.0.0.svn40).

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 persson 2856
9 schoenebeck 3072 * Gigasampler format engine:
10     - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
11     cutoff settings.
12    
13 persson 2837 * general changes:
14     - fixed printf type errors (mostly in debug messages)
15 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
16 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
17     allowing to sort data efficiently in real-time safe manner.
18     - RTList class: added methods for moving/inserting elements to arbitrary
19     position within a list.
20     - RTList class: added method fromPtr() for creating an Iterator object from
21     a raw element pointer.
22     - Attempt to partly fix resetting engine channels vs. resetting engine, an
23     overall cleanup of the Reset*(), ConnectAudioDevice(),
24     DisconnectAudioDevice() API methods would still be desirable though,
25     because the current situation is still inconsistent and error prone.
26 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
27     being directly assigned to a keyboard key. This allows more fine graded
28     processing of voices, which is i.e. required for certain instrument
29     script features.
30 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
31     (CC #64) events.
32     - Fix: Release trigger voices can now also distinguish correctly between
33     note-off and sustain pedal up events.
34 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
35     (while slow rate of crossfade smoother is preserved) to allow quick
36     volume and pan changes by instrument scripts for instance.
37 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
38     properly and thus were ignored for certain uses.
39 schoenebeck 3018 - Added new C++ API method
40     VirtualMidiDevice::SendChannelPressureToSampler().
41 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
42     sub threads is 16-byte aligned
43 schoenebeck 3054 - fixed numerous compiler warnings
44 persson 2837
45 schoenebeck 2866 * packaging changes:
46     - removed unnecessary dependency to libuuid
47     (originated by libgig's usage of it)
48 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
49     auto detect whether it (sh/c)ould output its messages in color.
50 schoenebeck 2866
51 schoenebeck 2871 * Real-time instrument scripts:
52     - Implemented scheduler for delayed MIDI events and for suspended scripts.
53     - Built-in script function "wait()": implemented support for function's
54     "duration-us" argument, thus scripts using this function are now
55     correctly resumed after the requested amount of microseconds.
56     - Built-in script function "play_note()": implemented support for
57     function's "duration-us" argument, thus notes triggered with this
58     argument are now correctly released after the requested amount of
59     microseconds.
60     - Fix: script events were not cleared when engine channel was reset,
61     potentially causing undefined behavior.
62     - Fixed crash which happened when trying to reference an undeclared
63     variable.
64 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
65     special value -1 for "duration-us" argument, which will cause the
66     triggered note to be released once the original note was released.
67 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
68     - Added new API method ScriptVM::syntaxHighlighting() which provides
69     a convenient syntax highlighting backend for external instrument
70     script editor applications.
71 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
72     - Extended parser issues to provide not only first line and first
73     column, but also last line and last column of issue (thus marking
74     the precise span of the issue within the source code).
75 schoenebeck 2902 - Reload script automatically after being modified by an instrument
76     editor.
77 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
78     like "on note end on".
79 schoenebeck 2931 - Implemented built-in script function "change_vol()".
80     - Implemented built-in script function "change_tune()".
81     - Implemented built-in script function "change_pan()".
82 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
83     - Implemented built-in script function "change_reso()".
84     - Implemented built-in script function "event_status()".
85     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
86     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
87     "event_status()" function.
88     - NKSP language: Added support for bitwise operators ".or.", ".and."
89     and ".not.".
90     - NKSP language scanner: Fixed IDs matching to require at least one
91     character (i.e. when matching function names or variable names).
92     - NKSP language scanner: disabled unusued rules.
93 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
94     be distinguished engine internally from "real" MIDI note on/off
95     events in order to avoid misbehaviors like hanging notes.
96 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
97     - Implemented built-in script variable "$NKSP_REAL_TIMER".
98     - Implemented built-in script variable "$NKSP_PERF_TIMER".
99     - Implemented built-in script variable "$ENGINE_UPTIME".
100 schoenebeck 2945 - Implemented built-in script function "inc()".
101     - Implemented built-in script function "dec()".
102     - NKSP language fix: division expressions were evaluated too often.
103     - NKSP language fix: string concatenation operator was right
104     associative instead of left (to right).
105 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
106     (i.e. "if end if").
107 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
108     - Implemented built-in script variable "$NI_CALLBACK_ID".
109     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
110     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
111     - Added support for read-only built-in variables (respectively
112     handled by the script parser).
113     - Added built-in script constant "$NI_CB_TYPE_INIT".
114     - Added built-in script constant "$NI_CB_TYPE_NOTE".
115     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
116     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
117 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
118 schoenebeck 2953 - Implemented built-in script function "change_attack()".
119     - Implemented built-in script function "change_decay()".
120     - Implemented built-in script function "change_release()".
121 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
122     synthesis parameter changes immediately in case the respective note
123     was triggered at the same time, instead of scheduling the parameter
124     change, especially because it would cause some parameter types's
125     changes either to be ramped (i.e. change_vol()) or other types even
126     to have not effect at all (i.e. change_attack()).
127 schoenebeck 2965 - Implemented built-in script function "sh_left()".
128     - Implemented built-in script function "sh_right()".
129 schoenebeck 2970 - Implemented built-in script function "min()".
130     - Implemented built-in script function "max()".
131 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
132     was loaded.
133     - NKSP built-in wait() script function: abort script execution if
134     a negative or zero wait time was passed as argument (since this is
135     a common indication of a bug either of the script or even of the
136     engine, which could lead to RT instability or even worse).
137 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
138     threatening scripts.
139 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
140 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
141     initializer list to an array variable.
142 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
143 schoenebeck 3076 - Implemented built-in script function "in_range()".
144 schoenebeck 2871
145 schoenebeck 3050 * Instruments DB:
146     - Fixed memory access bug of general DB access code which lead to
147     undefined behavior.
148 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
149     - The instrument DB path of linuxsampler's --create-instruments-db argument
150     is now optional, if it is missing, then a default location is used.
151 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
152     - Added support for scanning Sound Font (.sf2) files.
153 schoenebeck 3050

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

190 persson 2519 - enabled automake 'subdir-objects' option and moved external
191     source references (vst, au, asio) from makefiles to cpp files,
192     in order to get rid of warnings from automake 1.14
193 persson 2382
194 persson 2086 * general changes:
195 iliev 2012 - Refactoring: moved the independent code from
196     the Gigasampler format engine to base classes
197 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
198     respective profiling code is currently broken
199 schoenebeck 2053 - Introduced support for optional environment variable
200     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
201     where the sampler shall look for instrument editor plugins
202     (patch by Luis Garrido, slightly modified).
203 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
204     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
205     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
206     note (in this implementation of the sampler its simply hard routed to
207     the 1st effect send of the sampler channel, no matter what the actual
208     effect type is)
209     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
210     note (in this implementation of the sampler its simply hard routed to
211     the 2nd effect send of the sampler channel, no matter what the actual
212     effect type is)
213 schoenebeck 2124 - implemented support for internal LADSPA effects
214 schoenebeck 2140 - raised limit of program change queue from 100 to 512
215     (as suggested by Alex Stone)

218 iliev 2306 - added command line option --exec-after-init
219 schoenebeck 2330 - Introduced new C++ API method:
220     EngineChannel::InstrumentFileName(int index)
221     allowing to retrieve the whole list of files used for the loaded
222     instrument on an engine channel (a.k.a. part). Some GigaStudio
223     instruments for example are splitted over several files like
224     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
225 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
226     - Added new C++ API method Sampler::GetGlobalMaxStreams().
227     - Added new C++ API method Sampler::SetGlobalMaxVoices().
228     - Added new C++ API method Sampler::SetGlobalMaxStreams().
229 schoenebeck 2377 - Various "const" and "restrict" optimizations.
230 persson 2382 - all engines: add pan CC value to instrument pan parameter before
231     applying panning, instead of using two separate pan functions in
232     series (#182)
233 persson 2427 - added a lock guard class for exception safe mutex handling and
234     used it everywhere appropriate
235 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
236     - Exposed scale tuning to C++ API (along to the already existing standard
237     SysEx way).
238 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
239     and broken for ppc64. (Seq_cst loads and stores are actually not
240     used in LS, so the bug wasn't noticable.)
241     - lsatomic.h: added ARMv7 support
242 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
243     added various new C++ methods for this new feature / design change, old
244     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
245     as deprecated but are still there and should provide full behavior
246     backward compatibility).
247     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
248     unsafe and caused compilation error with clang 2.x).
249 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
250 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
251     sampler from the command line by providing LSCP aware features.
252 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
253     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
254     - VirtualMidiDevice: Added support for pitch bend.
255 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
256     polyphonic key pressure events (so far polyphonic pressure was not
257     supported at all, and channel pressure was rerouted as CC128 but not
258     used so far).
259 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
260     code is shared by all sampler engine implemementations, however only the
261     gig file format currently provides support for storing instrument scripts
262     (as LinuxSampler extension to the original GigaStudio 4 format).
263 iliev 2012
264 persson 2043 * Gigasampler format engine:
265     - implemented the "round robin keyboard" dimension
266     - fixed round robin and random dimensions for cases when number of
267     dimension zones is not a power of two
268     - made round robin use a counter for each region instead of each
269     key
270 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
271     - bugfix: filter keyboard tracking was broken
272     - filter performance fix (an unnecessary copy was made of the
273     filter parameters in each sub fragment)
274     - handle special case when pan parameter in gig file has max or
275     min value
276 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
277     doesn't sound naturally with a drumkit
278 persson 2408 - fixed EG1 modulation when attack or release is zero
279 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
280 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
281     conditions (see also previous commit on libgig).
282 persson 2673 - fixed behaviour of filter LFO
283 persson 2043
284 schoenebeck 2047 * SFZ format engine:
285 iliev 2012 - Initial implementation (not usable yet)
286 persson 2055 - added support for v2 multiple stage envelope generators
287     - added a fine-tuned v1 envelope generator instead of using the
288     one from the gig engine
289 persson 2058 - fixed memory leak and memory handling errors
290 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
291 persson 2058 - allow non-numerical key values ("C#4" for example)
292     - "key" opcode now sets pitch_keycenter too
293     - fixed error when unloading instrument with same sample used by
294     multiple regions

302     - fine-tuned the default velocity curve
303 persson 2086 - added support for transpose
304     - fixed crash when using sw_down/up
305     - improved logic for sw_lokey/hikey/up/down/last
306     - added more v1 aliases to parser
307 persson 2091 - reduced memory usage for sfz data
308 persson 2101 - RT-safeness: avoid malloc in audio thread
309     - fixed a bug that could cause voice stealing to fail
310 persson 2106 - optimized sample lookup
311 persson 2114 - improved support for exclusive groups (group, off_by and
312     off_mode)
313 persson 2115 - added support for controller triggered regions (on_locc/on_hicc)
314     - added support for loop_mode=one_shot
315 persson 2119 - fixed playback of 16 bit wav files on big endian CPUs
316     - added support for Ogg Vorbis sample files
317 persson 2167 - use loop markers from sample file if loop_start and loop_end are
318     not set in sfz file
319 persson 2175 - implemeted filters. Filter types: lowpass, bandpass, bandreject

321     cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
322     cutoff_cc, cutoff_chanaft.
323     - bugfix: zero ampeg_sustain didn't work
324 persson 2176 - added support for velocity effect on amplifier envelope time
325     (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
326     ampeg_vel2release)
327 persson 2203 - added support for EG hold (ampeg_hold)

690     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
691     practically irrelevant, however it caused problems with the new LSCP
692     shell's auto completion feature).
693 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
694     after each other (fixes #231).

697 schoenebeck 1599
698 schoenebeck 1639 * packaging changes:
699     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
700     causing e.g. the libgig test to fail when
701     "./configure --disable-jack-driver" was used
702     (patch by Alexis Ballier)

717 schoenebeck 1639
718 schoenebeck 1601 * general changes:

720     load as we used a non-portable Linux specific struct field
721     (fixes bug #70, patch by Ronald Baljeu)
722 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
723     plugin DLL on Windows systems failed
724 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
725     - optimized the SynchronizedConfig class so it doesn't wait
726     unnecessarily long after an update
727 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
728     events (e.g. to highlight the pressed keys on the virtual keyboard
729     of gigedit)
730 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
731 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
732 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
733     is only used by very few systems, most pick the int math
734     implementation, which is usually faster)
735 persson 1748 - fixes for audio drivers with varying buffer sizes
736 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
737     VST plugin

742 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
743 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
744 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
745     be switched on by command line option "--stacktrace" (the automatic
746     stacktrace mechanism seems to be broken on most systems at the moment)
747 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
748     a pointer to the launched InstrumentEditor object
749 schoenebeck 1876 - added optional 3rd party user data parameter for following
750     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
751     InstrumentEditor::Launch(),

753 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
754     model more strictly
755 persson 1895 - fixes for using large audio device buffers
756 persson 1951 - Windows: add the installation directory to the DLL search path

760 schoenebeck 1601
761 schoenebeck 1599 * audio driver:
762     - removed the nonsense audio channel constraint (which was hard coded to
763     max. 100 audio channels) for most audio drivers
764 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
765     opposed to the LSCP specs
766 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
767     reflected the wrong value
768 persson 1644 - fixed a memory management bug in ASIO driver
769 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
770 persson 1777 - JACK: use jack_client_open instead of the deprecated
771 persson 1748 jack_client_new
772 iliev 1829 - added (experimental) CoreAudio driver
773 persson 1888 - applied old fixes to the ASIO driver that were included in the
774     previous binary release but accidentally never committed to CVS
775     (fixes #117)
776 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
777     win64)
778 persson 1895 - VST: added support for sample rate and buffer size changes
779     - VST: close editor (Fantasia) when the VST is removed

784     stereo
785 persson 1922 - added channel routing, fxsends and midi maps to the settings
786     stored in the plugin state
787 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
788     AudioChannel::CopyTo() methods using GCC vector exensions
789     (if available)
790 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
791     exception when getting parameters from a disconnected device
792 schoenebeck 1599
793 persson 1651 * MIDI driver:
794     - added JACK MIDI driver
795 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
796     want to (mis)use it for some purpose ("fixed" in all current MIDI
797     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
798 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
799 persson 1887 CoreMidi or AU
800 persson 1889 - fixed mingw-w64 compilation error in MME driver
801 persson 1924 - made program change handling in MIDI thread real-time safe by
802     moving the logic to a non-RT thread
803 persson 1951 - fixed minor memory leak in ALSA driver
804 persson 1651
805 schoenebeck 1604 * instruments database:
806 iliev 1603 - avoid time consuming samples scanning when adding instruments
807     to the instruments database
808 iliev 1727 - added support for handling lost files in the instruments database
809 iliev 1781 - Implemented option for adding instruments in separate directories
810     in the instruments database
811     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
812 persson 1908 - work-around for missing fnmatch function on Windows to make
813     instrument database compilable
814 schoenebeck 1930 - added instrument database support on Windows
815     works with both standalone mode and VST plugin.
816     the instruments DB file is located in
817     %USERPROFILE%\.linuxsampler\instruments.db which allows different
818     databases for each windows user
819     if no DB is present it automatically creates the .linuxsampler subdir
820     and then creates an empty DB
821 persson 1943 - fixed recursive import, which was broken on Windows
822 iliev 1603
823 persson 1644 * Gigasampler format engine:
824     - fixed a memory leak that could happen when a channel was deleted
825     while notes were playing
826 persson 1646 - made it possible to load an instrument even if the audio thread
827     isn't running
828 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
829     enough for piano gigs with pedal noise samples
830 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
831     respective FX send MIDI controller was used
832 schoenebeck 1724 - added support for GM global device volume SysEx message
833 schoenebeck 1762 (can be selected at compile time to either apply globally to the
834     whole sampler [default] or only to the sampler channels that are
835     connected to the respective MIDI input port the SysEx message arrived
836     on)
837 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
838     sometimes wrongly killed in the same buffer, causing no sound to
839     be played
840 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
841     which is usally used to switch a part between chromatic sounds and
842     drumkit sounds (as opposed to their common default setting of MIDI
843     part 10 being a drumkit part and all other ones chromatic parts), in
844     LS however one can switch between the first 16 MIDI instrument maps
845     defined for the sampler
846 persson 1764 - made it possible to create multiple sample channels even if the
847     audio thread isn't running
848 persson 1844 - fixed crash when removing channel with active voices (#116)
849 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
850     un-cache the respective sample if it's really not used by any
851     sampler engine anymore
852     - re-cache samples in case they were changed by an instrument editor,
853     e.g. when a sample was added while playing (#82)
854 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
855     same time stamp as the voice's note-on event and occured both in the
856     same audio fragment cycle (fixes bug #112)
857 persson 1858 - added support for the "fine tune" and "pitch bend range"
858     instrument-level gig parameters
859     - fixed minor artifacts in pitch bend handling
860 schoenebeck 1860 - added support for GS Reset SysEx message
861 persson 1862 - allow gig files to use unlimited downward pitch shifting
862     - added a limit check for upward pitch shifting
863 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
864     note was silent
865 persson 1923 - fixed crash happening when a pitch bend event arrived at the
866     same time a new instrument was loading
867 persson 1644
868 schoenebeck 1687 * LSCP server:
869     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
870     react on MIDI data arriving on certain sampler channels (so far only
871     Note-On and Note-Off events are sent via this LSCP event)
872 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
873     react on MIDI data arriving on certain MIDI input devices (so far only
874     Note-On and Note-Off events are sent via this LSCP event)
875 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
876     SET DB_INSTRUMENT FILE_PATH
877 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
878     frontends to send MIDI messages to specific sampler channel
879     - added two additional fields to GET FILE INSTRUMENT INFO command -
880     KEY_BINDINGS and KEYSWITCH_BINDINGS
881 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
882     was incorrect
883 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
884 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
885     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
886     be triggered respectively
887     - added new LSCP command "SET STREAMS" to globally alter the maximum
888     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
889     which will be triggered respectively
890 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
891     a gigedit file dialog is opened)
892 iliev 1848 - close all connections when LSCPServer is deleted
893 iliev 1882 - hard close of all sockets on exit
894 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
895     driver
896 schoenebeck 1687
897 iliev 1761 * Bug fixes:
898     - fixed a crash which occurs when removing a sampler channel waiting
899     to start instrument loading after another channel
900 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
901     instrument loading in progress (bug #113)
902 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
903     instrument with PERSISTENT load mode
904 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
905     - fixed memory leaks when issuing the following LSCP commands:
906     GET AUDIO_OUTPUT_DRIVER INFO
907     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
908     GET MIDI_INPUT_DRIVER INFO
909     GET MIDI_INPUT_DRIVER_PARAMETER INFO
910     - fixed possible compilation error when sqlite is not present
911 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
912 iliev 1847 - fixed crash when changing the audio output device of a sampler
913     channel with loaded instrument and start playing notes
914 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
915 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
916     PowerPC, which probably could cause crashes on that platform
917 persson 1889 - fixed a memory management error which could cause a crash when a
918     plugin was unloaded
919 persson 1896 - bugfix: two private structs had the same name, which could cause
920     problems if the linker chose the wrong constructor
921 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
922     Windows
923 iliev 1761
924    
925 schoenebeck 1560 Version 0.5.1 (6 December 2007)
926 schoenebeck 1454
927     * packaging changes:
928     - added autoconf checks for pthread library
929     - added autoconf check for pthread bug found on certain NPTL-enabled
930     glibc versions (see Gentoo bug report #194076)
931 senoner 1502 - added autoconf checks for MS Windows
932 schoenebeck 1454
933 persson 1455 * general changes:
934     - bugfix: the thread used by an editor plugin didn't die when the
935     editor closed
936 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
937     out all the space. operator--() did not apply size_mask after
938     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
939     order to avoid problems with the _NonVolatileReader functions.
940     - bugfix: Stream.h: added a missing divide by BytesPerSample in
941     GetWriteSpace(). Since this function is currently only used in
942     the stream's qsort() compare function, it didn't trigger any
943     bugs.
944     - Resampler.h, Synthesizer.h: cubic interpolation now works in
945     24bit mode too. Faster method to read 24bit words on little
946     endian machines (x86): replaced 3 byte reads + shifts with a 1
947     unaligned 32bit read and shift
948     - experimental support for MS Windows (MIDI input via MME, AUDIO
949     output via ASIO)
950     - made handling of SIGINT signal (Ctrl-C) a bit more robust
951 iliev 1541 - support for monitoring the total number of active disk streams
952     (new LSCP commands: GET TOTAL_STREAM_COUNT,
953     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
954 persson 1455
955 senoner 1500 * AUDIO driver:
956 persson 1534 - added Windows ASIO low latency audio driver
957 senoner 1500
958 senoner 1485 * MIDI driver:
959 schoenebeck 1495 - added MME Windows MIDI driver
960 senoner 1485
961 schoenebeck 1471 * LSCP server:
962     - added support for Windows style path / filenames, however with
963     forward slash path separators instead of backslash
964     (i.e. "C:/foo/bar.gig")
965 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
966     apostrophes as well
967 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
968     "LIST FILE INSTRUMENTS <file>" and
969     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
970     about an arbitrary instrument file on the system where the sampler is
971     running on
972 schoenebeck 1471
973 schoenebeck 1424 Version 0.5.0 (15 October 2007)
974 schoenebeck 947
975 schoenebeck 1065 * packaging changes:
976 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
977     API header files anymore
978 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
979     the Doxygen API documentation (explicitly listed in Doxyfile.in)
980 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
981     capable to execute our autoconf environment, thus no need anymore
982     to maintain the compile time configuration file (osx/version.h) for
983     OSX manually (patch by Toshi Nagata)
984 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
985     parameters
986 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
987     C++ API header files, all implementation internal global definitions
988     are now in global_private.h
989     - atomic.h is not exposed to the C++ API anymore
990     - no need to include config.h anymore for using LS's API header files
991     - fixed warnings in API doc generation
992 schoenebeck 1065
993 schoenebeck 947 * general changes:
994     - replaced the old, confusing MIDI program change mechanism by a
995     flexible MIDI instrument mapper which allows to map arbitrary
996 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
997 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
998     loaded on the respective channel when such MIDI program change
999     messages arrive, beside that, each entry allows to define a life-time
1000     strategy for the instrument, so the user can define whether the
1001     instrument should i.e. be permanently loaded (to be able to switch
1002     quickly among sounds) or i.e. loaded just on demand when the
1003     respective program change arrives (to safe RAM space), as well as a
1004     global volume factor for each entry, so the user can adjust the volume
1005     dynamic of his mapped instrument collection without having to modify
1006 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1007     MIDI instrument maps and assign each sampler channel individually
1008     a certain map, so that i.e. separation of normal instruments and
1009     drumkits is possible
1010 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1011     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1012 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1013     due to a constant size RingBuffer FIFO which is now replaced by a
1014     dynamic (unlimited) size std::list FIFO
1015 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1016     output channels for being processed by external effect processors
1017     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1018     controllers
1019 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1020 iliev 1130 - Implemented new, improved notification system
1021 schoenebeck 1149 - fixed compilation errors regarding OSX
1022     (patch by Toshi Nagata)
1023 iliev 1161 - implemented instruments database
1024 iliev 1345 - added support for escape sequences to the instruments database
1025 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1026     within the sampler's process (by using instrument editor plugins),
1027     you'll notice the new "Registered instrument editors:" message on
1028 schoenebeck 1407 startup, added a new LSCP command:
1029     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1030 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1031     given sampler channel, the plugin path can be overridden at compile
1032     time with ./configure --enable-plugin-dir=/some/dir
1033 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1034     in the sampler's process to safely edit instruments while playing
1035     without a crash (hopefully) by either suspending single regions
1036     wherever possible or if unavoidable whole engine(s)
1037 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1038     policy and priority on thread level, set a minimum stack size for
1039     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1040     threads simply inherited properties of starting thread instead of
1041     setting their own policy and priority
1042 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1043     main process did not wait for the stack trace process to finish
1044     its output
1045 persson 1248 - fixed some minor memory leaks
1046 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1047     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1048 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1049     register, to avoid relocations in the text segment at runtime)
1050 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1051 schoenebeck 947
1052     * MIDI driver:
1053     - dispatch bank select (MSB and LSB) messages
1054    
1055 schoenebeck 1049 * audio driver:
1056     - the ALSA audio output driver parameters now reflect the correct
1057     parameter value ranges for the respective selected sound card
1058     (patch by Till Wimmer, a bit fixed and extended)
1059    
1060 persson 951 * Gigasampler format engine:
1061     - if a filter is used and EG2 finishes before EG1, let the voice
1062     die when EG2 has finished (this fixes a problem with clicks and
1063     voice starvation for some gigs)
1064 persson 1038 - playback is no longer disabled during instrument loading
1065     - all notes playing on a channel that changes its instrument keep
1066     playing with the old instrument until they get a note off
1067     command
1068 persson 1039 - EG fix: a release value of zero could cause noises or crash
1069 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1070 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1071     above max sustain level, which means that there is a decay phase
1072     even if sustain is 100%
1073 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1074     noises or crashes
1075 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1076 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1077     supplied to the configure script (fixes #46)
1078 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1079     instead of a fix value
1080 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1081     127 (solo mode) only kill voices if the respective mode really
1082     changed
1083 persson 951
1084 schoenebeck 1244 * LSCP server:
1085     - fixed compile time error for old Bison versions
1086     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1087 schoenebeck 1245 - parser now supports extended ASCII character set
1088     (up to ASCII code 255, i.e. includes now umlauts and accents)
1089     - filename arguments in LSCP commands now allow to use escape
1090     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1091     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1092     code value like \xf2) (fixes bug #24)
1093 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1094     least one of their text-based parameters (i.e. name, description):
1095     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1096     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1097     "SET DB_INSTRUMENT_DIRECTORY NAME",
1098     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1099     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1100     "FIND DB_INSTRUMENT_DIRECTORIES"
1101 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1102     occured, the unexpected character and the actually expected, possible
1103     character(s), the latter only if less than 5 possibilities)
1104 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1105     settings
1106 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1107     of strings were treated as being one string containing commas
1108     (fixes #57)
1109 schoenebeck 1244
1110 iliev 959 * Bug fixes:
1111     - fixed crash occurring on certain LSCP scripts (Bug 39)
1112 persson 1038 - another thread safety fix for lscp "load engine" and "set
1113     channel audio output device"
1114 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1115     on a sampler channel with connected MIDI device
1116 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1117     device connected to a sampler channel to number less then or equal
1118     to the index of the port to which the sampler channel is connected.
1119 iliev 1296 - The previous bindings were not been disconnected when altering
1120     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1121     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1122 iliev 1297 - The active stream/voice count statistic was incorrect.
1123 iliev 1298 - notification events were not been sent for some sampler
1124     channel changes
1125 iliev 1305 - added default min and max values to restrict the number of allowed
1126     audio output channels and MIDI input ports
1127 iliev 1306 - the connection to the PCM interface is now closed when destroying
1128     an audio output device
1129 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1130 iliev 959
1131 schoenebeck 1221 * test cases:
1132     - updated and fixed (haven't been touched in a while)
1133    
1134 schoenebeck 937 Version 0.4.0 (24 November 2006)
1135 persson 696
1136 schoenebeck 697 * packaging changes:
1137 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1138     to post-(un)install steps; added devel package for liblinuxsampler;
1139     to linuxsampler.spec (RPM)
1140 schoenebeck 697 - install necessary development header files for allowing 3rd party
1141     applications to link against liblinuxsampler
1142     - liblinuxsampler's API documentation can be generated with 'make docs'
1143     (Doxygen required)
1144 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1145     implementation (currently either an integer math solution or a
1146     di-harmonic approximation), automatic detection can be overriden
1147     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1148     configure script argument though (mandatory for cross-compilation)
1149 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1150     provided some on his own (as CXXFLAGS)
1151 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1152     messages
1153 schoenebeck 852 - added compile time options to allow disabling the various audio and
1154     MIDI drivers
1155 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1156     (patch by Ebrahim Mayat)
1157 schoenebeck 697
1158 persson 696 * Gigasampler format engine:
1159 schoenebeck 738 - extensive synthesis optimization
1160     (reimplementation of EGs and LFO(s), removed synthesis parameter
1161     prerendering and the synthesis parameter matrix in general, splitting
1162     each audio fragment into subfragments now where each subfragment uses
1163 persson 830 constant pitch and filter coefficients. The volume coefficient is
1164     linearly interpolated inside a subfragment, unless
1165     --disable-interpolate-volume is set.)
1166 persson 696 - fine tuning of the EG modulation parameters
1167 persson 729 - improved filter cutoff calculation by adding support for the
1168     following gig parameters: Cutoff freq (used when no cutoff
1169     controller is defined), Control invert, Minimum cutoff, Velocity
1170 persson 791 curve and Velocity range. The keyboard tracking now scales
1171     cutoff frequency instead of resonance.
1172 persson 877 - added support for gig parameter Resonance.
1173 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1174 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1175     which can be overridden with --enable-global-attenuation
1176 persson 783 - EG fixes: made the length of "attack hold" stage more
1177     accurate. Release stage can now start before attack stage
1178 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1179     time now has a minimal value to prevent clicks.
1180 persson 799 - fixed pitch changes larger than one octave
1181 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1182     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1183     all modes can be altered via standard GM messages, that is CC5 for
1184     altering portamento time, CC65 for enabling / disabling portamento
1185     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1186 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1187     parameter) and crossfade
1188 persson 831 - added support for the "attenuation controller threshold" gig
1189     parameter
1190 persson 832 - added smoothing of volume changes caused by control change
1191     messages
1192 persson 865 - sample loop parameters are now taken from the DimensionRegion
1193     instead of the wave chunk
1194     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1195     not equal to a power of two
1196 persson 877 - reimplementation of the filter algorithm. The new filter is more
1197     accurate and supports all gig filter types, including bandreject
1198     and lowpass turbo.
1199 persson 903 - real support for 24 bit samples - samples are not truncated to
1200     16 bits anymore
1201     - support for aftertouch (channel pressure, not polyphonic
1202     aftertouch)
1203 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1204     amplifying from 0)
1205 persson 696
1206 schoenebeck 711 * LSCP server:
1207     - fixed application exit on broken pipe error (fixes bug #20)
1208 iliev 793 - fixed the notification messages delay due to lack of
1209     network activity (fixes bug #26)
1210 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1211     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1212 schoenebeck 711
1213 schoenebeck 838 * audio driver:
1214     - added aRts audio output driver (by no means RT safe)
1215    
1216 schoenebeck 775 * MIDI driver:
1217     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1218     messages several times instead of once
1219 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1220     for events (i.e. for offline rendering based MIDI drivers)
1221 persson 922 - added checks for bad MIDI data
1222 schoenebeck 775
1223 schoenebeck 900 * linuxsampler application:
1224     - show available sampler engine types on startup
1225    
1226 schoenebeck 705 * general changes:
1227     - support for muting sampler channels and solo mode of the same, two new
1228     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1229     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1230     introduced for this, the behavior is the same like on a mixer console
1231 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1232     --enable-process-muted-channels which can be used to enable the
1233     processing of muted channels.
1234 iliev 777 - support for sostenuto pedal
1235 iliev 779 - support for monitoring the total number of active voices
1236 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1237     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1238 persson 835 - fixed some memory management errors
1239 persson 841 - fixed some concurrency problems that could lead to crashes when
1240     LSCP commands were executed
1241 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1242     sampler channel (fixes bug #36)
1243 schoenebeck 705
1244 schoenebeck 692 Version 0.3.3 (15 July 2005)
1245 schoenebeck 686
1246     * packaging changes:
1247     - fixed compilation with gcc 4.0
1248    
1249 schoenebeck 687 * Gigasampler format engine:
1250     - LFO preprocessing was performed even though the respective LFO was
1251     disabled by the instrument patch (minor efficiency fix)
1252 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1253     for volume ramp downs in the same fragment (needed for current voice
1254     stealing implementation) then simply inform the user with a warning
1255     about possible click sounds and reduce the volume ramp down
1256     appropriately instead of cancelling the audio device connection
1257 schoenebeck 687
1258 schoenebeck 677 Version 0.3.2 (24 June 2005)
1259 schoenebeck 609
1260     * packaging changes:
1261     - updated autotools build files to compile on OS X
1262     (conditional compilation of CoreMIDI and MidiShare drivers)
1263 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1264     './configure --disable-asm' (definitely not recommended)
1265 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1266     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1267     (due to 'dist-bzip2' automake option)
1268 schoenebeck 649
1269     * Gigasampler format engine:
1270     - support for the gig parameters for "release velocity response" curves
1271     - fine tuning of the EGADSR envelope
1272     - volume of release triggered samples now depends on note-on velocity,
1273     note length and gig parameter "release trigger decay" instead of
1274     note-off velocity.
1275 schoenebeck 663 - revised voice stealing
1276     (fixes crash and endless loop caused by voice stealing)
1277 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1278 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1279     instead of when the respective voice is actually launched
1280     (fixes undefined behavior if stolen voices belonged to a key group -
1281     this case was followed by a "killed voice survived" error message)
1282 schoenebeck 669 - fixed minor issue with null/silence samples
1283     (those stole voices even though they don't need a voice at all which
1284     resulted in "voice stealing didn't work out" messages)
1285 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1286     instrument or audio output device change
1287 schoenebeck 654
1288 schoenebeck 620 * LSCP server:
1289 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1290 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1291 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1292 schoenebeck 609
1293 schoenebeck 668 * linuxsampler application:
1294     - added command line parameters --lscp-addr and --lscp-port to override
1295     default IP address and port of LSCP server
1296    
1297 schoenebeck 579 Version 0.3.1 (24 May 2005)
1298    
1299     * initial release
