3    * packaging changes:    * packaging changes:
4        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5          causing e.g. the libgig test to fail when
6          "./configure --disable-jack-driver" was used
7          (patch by Alexis Ballier)
8    
9      * general changes:
10        - bugfix: on some POSIX systems instrument editor plugins refused to
11          load as we used a non-portable Linux specific struct field
12          (fixes bug #70, patch by Ronald Baljeu)
13        - fixed endless loop which occured when loading an instrument editor
14          plugin DLL on Windows systems failed
15        - fixed memory leaks that occurred when liblinuxsampler was unloaded
16        - optimized the SynchronizedConfig class so it doesn't wait
17          unnecessarily long after an update
18        - added support for notifying instrument editors on note-on / note-off
19          events (e.g. to highlight the pressed keys on the virtual keyboard
20          of gigedit)
21        - added support for triggering notes by instrument editors (see above)
22        - be verbose on DLL load errors (on Linux)
23        - fixed di-harmonic triangle LFO implementation (this LFO implementation
24          is only used by very few systems, most pick the int math
25          implementation, which is usually faster)
26    
27      * audio driver:
28        - removed the nonsense audio channel constraint (which was hard coded to
29          max. 100 audio channels) for most audio drivers
30        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
31          opposed to the LSCP specs
32        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
33          reflected the wrong value
34        - fixed a memory management bug in ASIO driver
35    
36      * MIDI driver:
37        - added JACK MIDI driver
38    
39      * instruments database:
40        - avoid time consuming samples scanning when adding instruments
41          to the instruments database
42    
43      * Gigasampler format engine:
44        - fixed a memory leak that could happen when a channel was deleted
45          while notes were playing
46        - made it possible to load an instrument even if the audio thread
47          isn't running
48    
49      * LSCP server:
50        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
51          react on MIDI data arriving on certain sampler channels (so far only
52          Note-On and Note-Off events are sent via this LSCP event)
53        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
54          react on MIDI data arriving on certain MIDI input devices (so far only
55          Note-On and Note-Off events are sent via this LSCP event)
56

59      * packaging changes:
60      - added autoconf checks for pthread library      - added autoconf checks for pthread library
61      - added autoconf check for pthread bug found on certain NPTL-enabled      - added autoconf check for pthread bug found on certain NPTL-enabled

80        - experimental support for MS Windows (MIDI input via MME, AUDIO
81          output via ASIO)
82        - made handling of SIGINT signal (Ctrl-C) a bit more robust
83        - support for monitoring the total number of active disk streams
84          (new LSCP commands: GET TOTAL_STREAM_COUNT,
85          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
