2    
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    
19      * audio driver:
20        - removed the nonsense audio channel constraint (which was hard coded to
21          max. 100 audio channels) for most audio drivers
22        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
23          opposed to the LSCP specs
24        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
25          reflected the wrong value
26        - fixed a memory management bug in ASIO driver
27    
28      * MIDI driver:
29        - added JACK MIDI driver
30    
31      * instruments database:
32        - avoid time consuming samples scanning when adding instruments
33          to the instruments database
34    
35      * Gigasampler format engine:
36        - fixed a memory leak that could happen when a channel was deleted
37          while notes were playing
38        - made it possible to load an instrument even if the audio thread
39          isn't running
40    
41    Version 0.5.1 (6 December 2007)
42    
43      * packaging changes:
44        - added autoconf checks for pthread library
45        - added autoconf check for pthread bug found on certain NPTL-enabled
46          glibc versions (see Gentoo bug report #194076)
47        - added autoconf checks for MS Windows
48    
49      * general changes:
50        - bugfix: the thread used by an editor plugin didn't die when the
51          editor closed
52        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
53          out all the space. operator--() did not apply size_mask after
54          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
55          order to avoid problems with the _NonVolatileReader functions.
56        - bugfix: Stream.h: added a missing divide by BytesPerSample in
57          GetWriteSpace(). Since this function is currently only used in
58          the stream's qsort() compare function, it didn't trigger any
59          bugs.
60        - Resampler.h, Synthesizer.h: cubic interpolation now works in
61          24bit mode too. Faster method to read 24bit words on little
62          endian machines (x86): replaced 3 byte reads + shifts with a 1
63          unaligned 32bit read and shift
64        - experimental support for MS Windows (MIDI input via MME, AUDIO
65          output via ASIO)
66        - made handling of SIGINT signal (Ctrl-C) a bit more robust
67        - support for monitoring the total number of active disk streams
68          (new LSCP commands: GET TOTAL_STREAM_COUNT,
69          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
70    
71      * AUDIO driver:
72        - added Windows ASIO low latency audio driver
73    
74      * MIDI driver:
75        - added MME Windows MIDI driver
76    
77      * LSCP server:
78        - added support for Windows style path / filenames, however with
79          forward slash path separators instead of backslash
80          (i.e. "C:/foo/bar.gig")
81        - allow naughty liblscp to send non-string device parameters within
82          apostrophes as well
83        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
84          "LIST FILE INSTRUMENTS <file>" and
85          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
86          about an arbitrary instrument file on the system where the sampler is
87          running on
88    
89    Version 0.5.0 (15 October 2007)
