File size: 69867 byte(s)
* Instruments DB: Fixed undefined DB transaction behavior.
* Fixed general compiler warnings.
* Bumped version (2.0.0.svn43).

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 3072 * Gigasampler format engine:
12     - 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 persson 2837
47 schoenebeck 2866 * packaging changes:
48     - removed unnecessary dependency to libuuid
49     (originated by libgig's usage of it)
50 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
51     auto detect whether it (sh/c)ould output its messages in color.
52 schoenebeck 2866
53 schoenebeck 2871 * Real-time instrument scripts:
54     - Implemented scheduler for delayed MIDI events and for suspended scripts.
55     - Built-in script function "wait()": implemented support for function's
56     "duration-us" argument, thus scripts using this function are now
57     correctly resumed after the requested amount of microseconds.
58     - Built-in script function "play_note()": implemented support for
59     function's "duration-us" argument, thus notes triggered with this
60     argument are now correctly released after the requested amount of
61     microseconds.
62     - Fix: script events were not cleared when engine channel was reset,
63     potentially causing undefined behavior.
64     - Fixed crash which happened when trying to reference an undeclared
65     variable.
66 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
67     special value -1 for "duration-us" argument, which will cause the
68     triggered note to be released once the original note was released.
69 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
70     - Added new API method ScriptVM::syntaxHighlighting() which provides
71     a convenient syntax highlighting backend for external instrument
72     script editor applications.
73 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
74     - Extended parser issues to provide not only first line and first
75     column, but also last line and last column of issue (thus marking
76     the precise span of the issue within the source code).
77 schoenebeck 2902 - Reload script automatically after being modified by an instrument
78     editor.
79 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
80     like "on note end on".
81 schoenebeck 2931 - Implemented built-in script function "change_vol()".
82     - Implemented built-in script function "change_tune()".
83     - Implemented built-in script function "change_pan()".
84 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
85     - Implemented built-in script function "change_reso()".
86     - Implemented built-in script function "event_status()".
87     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
88     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
89     "event_status()" function.
90     - NKSP language: Added support for bitwise operators ".or.", ".and."
91     and ".not.".
92     - NKSP language scanner: Fixed IDs matching to require at least one
93     character (i.e. when matching function names or variable names).
94     - NKSP language scanner: disabled unusued rules.
95 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
96     be distinguished engine internally from "real" MIDI note on/off
97     events in order to avoid misbehaviors like hanging notes.
98 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
99     - Implemented built-in script variable "$NKSP_REAL_TIMER".
100     - Implemented built-in script variable "$NKSP_PERF_TIMER".
101     - Implemented built-in script variable "$ENGINE_UPTIME".
102 schoenebeck 2945 - Implemented built-in script function "inc()".
103     - Implemented built-in script function "dec()".
104     - NKSP language fix: division expressions were evaluated too often.
105     - NKSP language fix: string concatenation operator was right
106     associative instead of left (to right).
107 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
108     (i.e. "if end if").
109 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
110     - Implemented built-in script variable "$NI_CALLBACK_ID".
111     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
112     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
113     - Added support for read-only built-in variables (respectively
114     handled by the script parser).
115     - Added built-in script constant "$NI_CB_TYPE_INIT".
116     - Added built-in script constant "$NI_CB_TYPE_NOTE".
117     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
118     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
119 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
120 schoenebeck 2953 - Implemented built-in script function "change_attack()".
121     - Implemented built-in script function "change_decay()".
122     - Implemented built-in script function "change_release()".
123 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
124     synthesis parameter changes immediately in case the respective note
125     was triggered at the same time, instead of scheduling the parameter
126     change, especially because it would cause some parameter types's
127     changes either to be ramped (i.e. change_vol()) or other types even
128     to have not effect at all (i.e. change_attack()).
129 schoenebeck 2965 - Implemented built-in script function "sh_left()".
130     - Implemented built-in script function "sh_right()".
131 schoenebeck 2970 - Implemented built-in script function "min()".
132     - Implemented built-in script function "max()".
133 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
134     was loaded.
135     - NKSP built-in wait() script function: abort script execution if
136     a negative or zero wait time was passed as argument (since this is
137     a common indication of a bug either of the script or even of the
138     engine, which could lead to RT instability or even worse).
139 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
140     threatening scripts.
141 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
142 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
143     initializer list to an array variable.
144 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
145 schoenebeck 3076 - Implemented built-in script function "in_range()".
146 schoenebeck 2871
147 schoenebeck 3050 * Instruments DB:
148     - Fixed memory access bug of general DB access code which lead to
149     undefined behavior.
150 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
151     - The instrument DB path of linuxsampler's --create-instruments-db argument
152     is now optional, if it is missing, then a default location is used.
153 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
154     - Added support for scanning Sound Font (.sf2) files.
155 schoenebeck 3101 - Fixed undefined DB transaction behavior.

168 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
169 persson 2197 - minor Makefile fix for building lscpparser when build and source

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

220 iliev 2296 - experimental support for per voice equalization
221 iliev 2306 - added command line option --exec-after-init
222 schoenebeck 2330 - Introduced new C++ API method:
223     EngineChannel::InstrumentFileName(int index)
224     allowing to retrieve the whole list of files used for the loaded
225     instrument on an engine channel (a.k.a. part). Some GigaStudio
226     instruments for example are splitted over several files like
227     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
228 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
229     - Added new C++ API method Sampler::GetGlobalMaxStreams().
230     - Added new C++ API method Sampler::SetGlobalMaxVoices().
231     - Added new C++ API method Sampler::SetGlobalMaxStreams().
232 schoenebeck 2377 - Various "const" and "restrict" optimizations.
233 persson 2382 - all engines: add pan CC value to instrument pan parameter before
234     applying panning, instead of using two separate pan functions in
235     series (#182)
236 persson 2427 - added a lock guard class for exception safe mutex handling and
237     used it everywhere appropriate
238 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
239     - Exposed scale tuning to C++ API (along to the already existing standard
240     SysEx way).
241 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
242     and broken for ppc64. (Seq_cst loads and stores are actually not
243     used in LS, so the bug wasn't noticable.)
244     - lsatomic.h: added ARMv7 support
245 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
246     added various new C++ methods for this new feature / design change, old
247     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
248     as deprecated but are still there and should provide full behavior
249     backward compatibility).
250     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
251     unsafe and caused compilation error with clang 2.x).
252 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
253 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
254     sampler from the command line by providing LSCP aware features.
255 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
256     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
257     - VirtualMidiDevice: Added support for pitch bend.
258 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
259     polyphonic key pressure events (so far polyphonic pressure was not
260     supported at all, and channel pressure was rerouted as CC128 but not
261     used so far).
262 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
263     code is shared by all sampler engine implemementations, however only the
264     gig file format currently provides support for storing instrument scripts
265     (as LinuxSampler extension to the original GigaStudio 4 format).
266 iliev 2012
267 persson 2043 * Gigasampler format engine:
268     - implemented the "round robin keyboard" dimension
269     - fixed round robin and random dimensions for cases when number of
270     dimension zones is not a power of two
271     - made round robin use a counter for each region instead of each
272     key
273 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
274     - bugfix: filter keyboard tracking was broken
275     - filter performance fix (an unnecessary copy was made of the
276     filter parameters in each sub fragment)
277     - handle special case when pan parameter in gig file has max or
278     min value
279 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
280     doesn't sound naturally with a drumkit
281 persson 2408 - fixed EG1 modulation when attack or release is zero
282 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
283 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
284     conditions (see also previous commit on libgig).
285 persson 2673 - fixed behaviour of filter LFO
286 persson 2043
287 schoenebeck 2047 * SFZ format engine:
288 iliev 2012 - Initial implementation (not usable yet)
289 persson 2055 - added support for v2 multiple stage envelope generators
290     - added a fine-tuned v1 envelope generator instead of using the
291     one from the gig engine
292 persson 2058 - fixed memory leak and memory handling errors
293 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
294 persson 2058 - allow non-numerical key values ("C#4" for example)
295     - "key" opcode now sets pitch_keycenter too
296     - fixed error when unloading instrument with same sample used by
297     multiple regions

305     - fine-tuned the default velocity curve
306 persson 2086 - added support for transpose
307     - fixed crash when using sw_down/up
308     - improved logic for sw_lokey/hikey/up/down/last
309     - added more v1 aliases to parser
310 persson 2091 - reduced memory usage for sfz data
311 persson 2101 - RT-safeness: avoid malloc in audio thread
312     - fixed a bug that could cause voice stealing to fail
313 persson 2106 - optimized sample lookup
314 persson 2114 - improved support for exclusive groups (group, off_by and
315     off_mode)

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

692 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
693     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
694     practically irrelevant, however it caused problems with the new LSCP
695     shell's auto completion feature).
696 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
697     after each other (fixes #231).

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

720 schoenebeck 1639
721 schoenebeck 1601 * general changes:
722     - bugfix: on some POSIX systems instrument editor plugins refused to
723     load as we used a non-portable Linux specific struct field
724     (fixes bug #70, patch by Ronald Baljeu)
725 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
726     plugin DLL on Windows systems failed
727 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
728     - optimized the SynchronizedConfig class so it doesn't wait
729     unnecessarily long after an update
730 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
731     events (e.g. to highlight the pressed keys on the virtual keyboard
732     of gigedit)
733 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
734 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
735 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
736     is only used by very few systems, most pick the int math
737     implementation, which is usually faster)
738 persson 1748 - fixes for audio drivers with varying buffer sizes
739 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
740     VST plugin

745 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
746 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
747 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
748     be switched on by command line option "--stacktrace" (the automatic
749     stacktrace mechanism seems to be broken on most systems at the moment)
750 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
751     a pointer to the launched InstrumentEditor object
752 schoenebeck 1876 - added optional 3rd party user data parameter for following
753     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
754     InstrumentEditor::Launch(),
755     InstrumentManager::LaunchInstrumentEditor()
756 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
757     model more strictly
758 persson 1895 - fixes for using large audio device buffers
759 persson 1951 - Windows: add the installation directory to the DLL search path

762 schoenebeck 2509 - updated linuxsampler man page
763 schoenebeck 1601
764 schoenebeck 1599 * audio driver:
765     - removed the nonsense audio channel constraint (which was hard coded to
766     max. 100 audio channels) for most audio drivers
767 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
768     opposed to the LSCP specs
769 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
770     reflected the wrong value
771 persson 1644 - fixed a memory management bug in ASIO driver
772 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
773 persson 1777 - JACK: use jack_client_open instead of the deprecated
774 persson 1748 jack_client_new
775 iliev 1829 - added (experimental) CoreAudio driver
776 persson 1888 - applied old fixes to the ASIO driver that were included in the
777     previous binary release but accidentally never committed to CVS
778     (fixes #117)
779 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
780     win64)
781 persson 1895 - VST: added support for sample rate and buffer size changes
782     - VST: close editor (Fantasia) when the VST is removed

787     stereo
788 persson 1922 - added channel routing, fxsends and midi maps to the settings
789     stored in the plugin state
790 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
791     AudioChannel::CopyTo() methods using GCC vector exensions
792     (if available)
793 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
794     exception when getting parameters from a disconnected device
795 schoenebeck 1599
796 persson 1651 * MIDI driver:
797     - added JACK MIDI driver
798 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
799     want to (mis)use it for some purpose ("fixed" in all current MIDI
800     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
801 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
802 persson 1887 CoreMidi or AU
803 persson 1889 - fixed mingw-w64 compilation error in MME driver
804 persson 1924 - made program change handling in MIDI thread real-time safe by
805     moving the logic to a non-RT thread
806 persson 1951 - fixed minor memory leak in ALSA driver
807 persson 1651
808 schoenebeck 1604 * instruments database:
809 iliev 1603 - avoid time consuming samples scanning when adding instruments
810     to the instruments database
811 iliev 1727 - added support for handling lost files in the instruments database
812 iliev 1781 - Implemented option for adding instruments in separate directories
813     in the instruments database
814     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
815 persson 1908 - work-around for missing fnmatch function on Windows to make
816     instrument database compilable
817 schoenebeck 1930 - added instrument database support on Windows
818     works with both standalone mode and VST plugin.
819     the instruments DB file is located in
820     %USERPROFILE%\.linuxsampler\instruments.db which allows different
821     databases for each windows user
822     if no DB is present it automatically creates the .linuxsampler subdir
823     and then creates an empty DB
824 persson 1943 - fixed recursive import, which was broken on Windows
825 iliev 1603
826 persson 1644 * Gigasampler format engine:
827     - fixed a memory leak that could happen when a channel was deleted
828     while notes were playing
829 persson 1646 - made it possible to load an instrument even if the audio thread
830     isn't running
831 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
832     enough for piano gigs with pedal noise samples
833 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
834     respective FX send MIDI controller was used
835 schoenebeck 1724 - added support for GM global device volume SysEx message
836 schoenebeck 1762 (can be selected at compile time to either apply globally to the
837     whole sampler [default] or only to the sampler channels that are
838     connected to the respective MIDI input port the SysEx message arrived
839     on)
840 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
841     sometimes wrongly killed in the same buffer, causing no sound to
842     be played
843 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
844     which is usally used to switch a part between chromatic sounds and
845     drumkit sounds (as opposed to their common default setting of MIDI
846     part 10 being a drumkit part and all other ones chromatic parts), in
847     LS however one can switch between the first 16 MIDI instrument maps
848     defined for the sampler
849 persson 1764 - made it possible to create multiple sample channels even if the
850     audio thread isn't running
851 persson 1844 - fixed crash when removing channel with active voices (#116)
852 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
853     un-cache the respective sample if it's really not used by any
854     sampler engine anymore
855     - re-cache samples in case they were changed by an instrument editor,
856     e.g. when a sample was added while playing (#82)
857 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
858     same time stamp as the voice's note-on event and occured both in the
859     same audio fragment cycle (fixes bug #112)
860 persson 1858 - added support for the "fine tune" and "pitch bend range"
861     instrument-level gig parameters
862     - fixed minor artifacts in pitch bend handling
863 schoenebeck 1860 - added support for GS Reset SysEx message
864 persson 1862 - allow gig files to use unlimited downward pitch shifting
865     - added a limit check for upward pitch shifting
866 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
867     note was silent
868 persson 1923 - fixed crash happening when a pitch bend event arrived at the
869     same time a new instrument was loading
870 persson 1644
871 schoenebeck 1687 * LSCP server:
872     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
873     react on MIDI data arriving on certain sampler channels (so far only
874     Note-On and Note-Off events are sent via this LSCP event)
875 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
876     react on MIDI data arriving on certain MIDI input devices (so far only
877     Note-On and Note-Off events are sent via this LSCP event)
878 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
879     SET DB_INSTRUMENT FILE_PATH
880 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
881     frontends to send MIDI messages to specific sampler channel
882     - added two additional fields to GET FILE INSTRUMENT INFO command -
883     KEY_BINDINGS and KEYSWITCH_BINDINGS
884 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
885     was incorrect
886 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
887 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
888     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
889     be triggered respectively
890     - added new LSCP command "SET STREAMS" to globally alter the maximum
891     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
892     which will be triggered respectively
893 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
894     a gigedit file dialog is opened)
895 iliev 1848 - close all connections when LSCPServer is deleted
896 iliev 1882 - hard close of all sockets on exit
897 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
898     driver
899 schoenebeck 1687
900 iliev 1761 * Bug fixes:
901     - fixed a crash which occurs when removing a sampler channel waiting
902     to start instrument loading after another channel
903 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
904     instrument loading in progress (bug #113)
905 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
906     instrument with PERSISTENT load mode
907 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
908     - fixed memory leaks when issuing the following LSCP commands:
909     GET AUDIO_OUTPUT_DRIVER INFO
910     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
911     GET MIDI_INPUT_DRIVER INFO
912     GET MIDI_INPUT_DRIVER_PARAMETER INFO
913     - fixed possible compilation error when sqlite is not present
914 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
915 iliev 1847 - fixed crash when changing the audio output device of a sampler
916     channel with loaded instrument and start playing notes
917 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
918 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
919     PowerPC, which probably could cause crashes on that platform
920 persson 1889 - fixed a memory management error which could cause a crash when a
921     plugin was unloaded
922 persson 1896 - bugfix: two private structs had the same name, which could cause
923     problems if the linker chose the wrong constructor
924 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
925     Windows
926 iliev 1761
927    
928 schoenebeck 1560 Version 0.5.1 (6 December 2007)
929 schoenebeck 1454
930     * packaging changes:
931     - added autoconf checks for pthread library
932     - added autoconf check for pthread bug found on certain NPTL-enabled
933     glibc versions (see Gentoo bug report #194076)
934 senoner 1502 - added autoconf checks for MS Windows
935 schoenebeck 1454
936 persson 1455 * general changes:
937     - bugfix: the thread used by an editor plugin didn't die when the
938     editor closed
939 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
940     out all the space. operator--() did not apply size_mask after
941     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
942     order to avoid problems with the _NonVolatileReader functions.
943     - bugfix: Stream.h: added a missing divide by BytesPerSample in
944     GetWriteSpace(). Since this function is currently only used in
945     the stream's qsort() compare function, it didn't trigger any
946     bugs.
947     - Resampler.h, Synthesizer.h: cubic interpolation now works in
948     24bit mode too. Faster method to read 24bit words on little
949     endian machines (x86): replaced 3 byte reads + shifts with a 1
950     unaligned 32bit read and shift
951     - experimental support for MS Windows (MIDI input via MME, AUDIO
952     output via ASIO)
953     - made handling of SIGINT signal (Ctrl-C) a bit more robust
954 iliev 1541 - support for monitoring the total number of active disk streams
955     (new LSCP commands: GET TOTAL_STREAM_COUNT,
956     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
957 persson 1455
958 senoner 1500 * AUDIO driver:
959 persson 1534 - added Windows ASIO low latency audio driver
960 senoner 1500
961 senoner 1485 * MIDI driver:
962 schoenebeck 1495 - added MME Windows MIDI driver
963 senoner 1485
964 schoenebeck 1471 * LSCP server:
965     - added support for Windows style path / filenames, however with
966     forward slash path separators instead of backslash
967     (i.e. "C:/foo/bar.gig")
968 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
969     apostrophes as well
970 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
971     "LIST FILE INSTRUMENTS <file>" and
972     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
973     about an arbitrary instrument file on the system where the sampler is
974     running on
975 schoenebeck 1471
976 schoenebeck 1424 Version 0.5.0 (15 October 2007)
977 schoenebeck 947
978 schoenebeck 1065 * packaging changes:
979 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
980     API header files anymore
981 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
982     the Doxygen API documentation (explicitly listed in Doxyfile.in)
983 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
984     capable to execute our autoconf environment, thus no need anymore
985     to maintain the compile time configuration file (osx/version.h) for
986     OSX manually (patch by Toshi Nagata)
987 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
988     parameters
989 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
990     C++ API header files, all implementation internal global definitions
991     are now in global_private.h
992     - atomic.h is not exposed to the C++ API anymore
993     - no need to include config.h anymore for using LS's API header files
994     - fixed warnings in API doc generation
995 schoenebeck 1065
996 schoenebeck 947 * general changes:
997     - replaced the old, confusing MIDI program change mechanism by a
998     flexible MIDI instrument mapper which allows to map arbitrary
999 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1000 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1001     loaded on the respective channel when such MIDI program change
1002     messages arrive, beside that, each entry allows to define a life-time
1003     strategy for the instrument, so the user can define whether the
1004     instrument should i.e. be permanently loaded (to be able to switch
1005     quickly among sounds) or i.e. loaded just on demand when the
1006     respective program change arrives (to safe RAM space), as well as a
1007     global volume factor for each entry, so the user can adjust the volume
1008     dynamic of his mapped instrument collection without having to modify
1009 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1010     MIDI instrument maps and assign each sampler channel individually
1011     a certain map, so that i.e. separation of normal instruments and
1012     drumkits is possible
1013 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1014     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1015 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1016     due to a constant size RingBuffer FIFO which is now replaced by a
1017     dynamic (unlimited) size std::list FIFO
1018 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1019     output channels for being processed by external effect processors
1020     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1021     controllers
1022 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1023 iliev 1130 - Implemented new, improved notification system
1024 schoenebeck 1149 - fixed compilation errors regarding OSX
1025     (patch by Toshi Nagata)
1026 iliev 1161 - implemented instruments database
1027 iliev 1345 - added support for escape sequences to the instruments database
1028 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1029     within the sampler's process (by using instrument editor plugins),
1030     you'll notice the new "Registered instrument editors:" message on
1031 schoenebeck 1407 startup, added a new LSCP command:
1032     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1033 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1034     given sampler channel, the plugin path can be overridden at compile
1035     time with ./configure --enable-plugin-dir=/some/dir
1036 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1037     in the sampler's process to safely edit instruments while playing
1038     without a crash (hopefully) by either suspending single regions
1039     wherever possible or if unavoidable whole engine(s)
1040 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1041     policy and priority on thread level, set a minimum stack size for
1042     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1043     threads simply inherited properties of starting thread instead of
1044     setting their own policy and priority
1045 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1046     main process did not wait for the stack trace process to finish
1047     its output
1048 persson 1248 - fixed some minor memory leaks
1049 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1050     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1051 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1052     register, to avoid relocations in the text segment at runtime)
1053 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1054 schoenebeck 947
1055     * MIDI driver:
1056     - dispatch bank select (MSB and LSB) messages
1057    
1058 schoenebeck 1049 * audio driver:
1059     - the ALSA audio output driver parameters now reflect the correct
1060     parameter value ranges for the respective selected sound card
1061     (patch by Till Wimmer, a bit fixed and extended)
1062    
1063 persson 951 * Gigasampler format engine:
1064     - if a filter is used and EG2 finishes before EG1, let the voice
1065     die when EG2 has finished (this fixes a problem with clicks and
1066     voice starvation for some gigs)
1067 persson 1038 - playback is no longer disabled during instrument loading
1068     - all notes playing on a channel that changes its instrument keep
1069     playing with the old instrument until they get a note off
1070     command
1071 persson 1039 - EG fix: a release value of zero could cause noises or crash
1072 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1073 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1074     above max sustain level, which means that there is a decay phase
1075     even if sustain is 100%
1076 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1077     noises or crashes
1078 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1079 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1080     supplied to the configure script (fixes #46)
1081 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1082     instead of a fix value
1083 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1084     127 (solo mode) only kill voices if the respective mode really
1085     changed
1086 persson 951
1087 schoenebeck 1244 * LSCP server:
1088     - fixed compile time error for old Bison versions
1089     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1090 schoenebeck 1245 - parser now supports extended ASCII character set
1091     (up to ASCII code 255, i.e. includes now umlauts and accents)
1092     - filename arguments in LSCP commands now allow to use escape
1093     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1094     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1095     code value like \xf2) (fixes bug #24)
1096 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1097     least one of their text-based parameters (i.e. name, description):
1098     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1099     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1100     "SET DB_INSTRUMENT_DIRECTORY NAME",
1101     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1102     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1103     "FIND DB_INSTRUMENT_DIRECTORIES"
1104 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1105     occured, the unexpected character and the actually expected, possible
1106     character(s), the latter only if less than 5 possibilities)
1107 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1108     settings
1109 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1110     of strings were treated as being one string containing commas
1111     (fixes #57)
1112 schoenebeck 1244
1113 iliev 959 * Bug fixes:
1114     - fixed crash occurring on certain LSCP scripts (Bug 39)
1115 persson 1038 - another thread safety fix for lscp "load engine" and "set
1116     channel audio output device"
1117 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1118     on a sampler channel with connected MIDI device
1119 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1120     device connected to a sampler channel to number less then or equal
1121     to the index of the port to which the sampler channel is connected.
1122 iliev 1296 - The previous bindings were not been disconnected when altering
1123     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1124     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1125 iliev 1297 - The active stream/voice count statistic was incorrect.
1126 iliev 1298 - notification events were not been sent for some sampler
1127     channel changes
1128 iliev 1305 - added default min and max values to restrict the number of allowed
1129     audio output channels and MIDI input ports
1130 iliev 1306 - the connection to the PCM interface is now closed when destroying
1131     an audio output device
1132 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1133 iliev 959
1134 schoenebeck 1221 * test cases:
1135     - updated and fixed (haven't been touched in a while)
1136    
1137 schoenebeck 937 Version 0.4.0 (24 November 2006)
1138 persson 696
1139 schoenebeck 697 * packaging changes:
1140 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1141     to post-(un)install steps; added devel package for liblinuxsampler;
1142     to linuxsampler.spec (RPM)
1143 schoenebeck 697 - install necessary development header files for allowing 3rd party
1144     applications to link against liblinuxsampler
1145     - liblinuxsampler's API documentation can be generated with 'make docs'
1146     (Doxygen required)
1147 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1148     implementation (currently either an integer math solution or a
1149     di-harmonic approximation), automatic detection can be overriden
1150     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1151     configure script argument though (mandatory for cross-compilation)
1152 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1153     provided some on his own (as CXXFLAGS)
1154 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1155     messages
1156 schoenebeck 852 - added compile time options to allow disabling the various audio and
1157     MIDI drivers
1158 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1159     (patch by Ebrahim Mayat)
1160 schoenebeck 697
1161 persson 696 * Gigasampler format engine:
1162 schoenebeck 738 - extensive synthesis optimization
1163     (reimplementation of EGs and LFO(s), removed synthesis parameter
1164     prerendering and the synthesis parameter matrix in general, splitting
1165     each audio fragment into subfragments now where each subfragment uses
1166 persson 830 constant pitch and filter coefficients. The volume coefficient is
1167     linearly interpolated inside a subfragment, unless
1168     --disable-interpolate-volume is set.)
1169 persson 696 - fine tuning of the EG modulation parameters
1170 persson 729 - improved filter cutoff calculation by adding support for the
1171     following gig parameters: Cutoff freq (used when no cutoff
1172     controller is defined), Control invert, Minimum cutoff, Velocity
1173 persson 791 curve and Velocity range. The keyboard tracking now scales
1174     cutoff frequency instead of resonance.
1175 persson 877 - added support for gig parameter Resonance.
1176 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1177 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1178     which can be overridden with --enable-global-attenuation
1179 persson 783 - EG fixes: made the length of "attack hold" stage more
1180     accurate. Release stage can now start before attack stage
1181 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1182     time now has a minimal value to prevent clicks.
1183 persson 799 - fixed pitch changes larger than one octave
1184 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1185     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1186     all modes can be altered via standard GM messages, that is CC5 for
1187     altering portamento time, CC65 for enabling / disabling portamento
1188     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1189 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1190     parameter) and crossfade
1191 persson 831 - added support for the "attenuation controller threshold" gig
1192     parameter
1193 persson 832 - added smoothing of volume changes caused by control change
1194     messages
1195 persson 865 - sample loop parameters are now taken from the DimensionRegion
1196     instead of the wave chunk
1197     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1198     not equal to a power of two
1199 persson 877 - reimplementation of the filter algorithm. The new filter is more
1200     accurate and supports all gig filter types, including bandreject
1201     and lowpass turbo.
1202 persson 903 - real support for 24 bit samples - samples are not truncated to
1203     16 bits anymore
1204     - support for aftertouch (channel pressure, not polyphonic
1205     aftertouch)
1206 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1207     amplifying from 0)
1208 persson 696
1209 schoenebeck 711 * LSCP server:
1210     - fixed application exit on broken pipe error (fixes bug #20)
1211 iliev 793 - fixed the notification messages delay due to lack of
1212     network activity (fixes bug #26)
1213 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1214     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1215 schoenebeck 711
1216 schoenebeck 838 * audio driver:
1217     - added aRts audio output driver (by no means RT safe)
1218    
1219 schoenebeck 775 * MIDI driver:
1220     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1221     messages several times instead of once
1222 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1223     for events (i.e. for offline rendering based MIDI drivers)
1224 persson 922 - added checks for bad MIDI data
1225 schoenebeck 775
1226 schoenebeck 900 * linuxsampler application:
1227     - show available sampler engine types on startup
1228    
1229 schoenebeck 705 * general changes:
1230     - support for muting sampler channels and solo mode of the same, two new
1231     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1232     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1233     introduced for this, the behavior is the same like on a mixer console
1234 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1235     --enable-process-muted-channels which can be used to enable the
1236     processing of muted channels.
1237 iliev 777 - support for sostenuto pedal
1238 iliev 779 - support for monitoring the total number of active voices
1239 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1240     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1241 persson 835 - fixed some memory management errors
1242 persson 841 - fixed some concurrency problems that could lead to crashes when
1243     LSCP commands were executed
1244 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1245     sampler channel (fixes bug #36)
1246 schoenebeck 705
1247 schoenebeck 692 Version 0.3.3 (15 July 2005)
1248 schoenebeck 686
1249     * packaging changes:
1250     - fixed compilation with gcc 4.0
1251    
1252 schoenebeck 687 * Gigasampler format engine:
1253     - LFO preprocessing was performed even though the respective LFO was
1254     disabled by the instrument patch (minor efficiency fix)
1255 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1256     for volume ramp downs in the same fragment (needed for current voice
1257     stealing implementation) then simply inform the user with a warning
1258     about possible click sounds and reduce the volume ramp down
1259     appropriately instead of cancelling the audio device connection
1260 schoenebeck 687
1261 schoenebeck 677 Version 0.3.2 (24 June 2005)
1262 schoenebeck 609
1263     * packaging changes:
1264     - updated autotools build files to compile on OS X
1265     (conditional compilation of CoreMIDI and MidiShare drivers)
1266 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1267     './configure --disable-asm' (definitely not recommended)
1268 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1269     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1270     (due to 'dist-bzip2' automake option)
1271 schoenebeck 649
1272     * Gigasampler format engine:
1273     - support for the gig parameters for "release velocity response" curves
1274     - fine tuning of the EGADSR envelope
1275     - volume of release triggered samples now depends on note-on velocity,
1276     note length and gig parameter "release trigger decay" instead of
1277     note-off velocity.
1278 schoenebeck 663 - revised voice stealing
1279     (fixes crash and endless loop caused by voice stealing)
1280 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1281 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1282     instead of when the respective voice is actually launched
1283     (fixes undefined behavior if stolen voices belonged to a key group -
1284     this case was followed by a "killed voice survived" error message)
1285 schoenebeck 669 - fixed minor issue with null/silence samples
1286     (those stole voices even though they don't need a voice at all which
1287     resulted in "voice stealing didn't work out" messages)
1288 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1289     instrument or audio output device change
1290 schoenebeck 654
1291 schoenebeck 620 * LSCP server:
1292 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1293 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1294 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1295 schoenebeck 609
1296 schoenebeck 668 * linuxsampler application:
1297     - added command line parameters --lscp-addr and --lscp-port to override
1298     default IP address and port of LSCP server
1299    
1300 schoenebeck 579 Version 0.3.1 (24 May 2005)
1301    
1302     * initial release
