3      * packaging changes:
4        - config.h is not going to be installed along with liblinuxsampler's
5          API header files anymore
6        - only the API relevant header (and source) files will be exported to
7          the Doxygen API documentation (explicitly listed in Doxyfile.in)
8        - added completely new XCode project files for Mac OSX which is now
9          capable to execute our autoconf environment, thus no need anymore
10          to maintain the compile time configuration file (osx/version.h) for
11          OSX manually (patch by Toshi Nagata)

39      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
40        - Implemented new, improved notification system
41        - fixed compilation errors regarding OSX
42          (patch by Toshi Nagata)
43        - implemented instruments database
44        - added highly experimental support for on-the-fly instrument editing
45          within the sampler's process (by using instrument editor plugins),
46          you'll notice the new "Registered instrument editors:" message on
47          startup, added a new LSCP command "EDIT INSTRUMENT <sampler-channel>"
48          to spawn a matching instrument editor for the instrument on the
49          given sampler channel, the plugin path can be overridden at compile
50          time with ./configure --enable-plugin-dir=/some/dir
51        - added experimental code for synchronizing instrument editors hosted
52          in the sampler's process to safely edit instruments while playing
53          without a crash (hopefully) by either suspending single regions
54          wherever possible or if unavoidable whole engine(s)
55        - fixed several issues in fundamental "Thread" class: set scheduling
56          policy and priority on thread level, set a minimum stack size for
57          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
58          threads simply inherited properties of starting thread instead of
59          setting their own policy and priority
60        - minor fix in our automatic stack trace mechanism on crashes, the
61          main process did not wait for the stack trace process to finish
62          its output
63        - fixed some minor memory leaks
64        - reenabled assembly features support, at the moment only for
65          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
66        - minor assembly fix in x86 features detection (don't use the PIC
67          register, to avoid relocations in the text segment at runtime)

69    * MIDI driver:    * MIDI driver:
70      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
71    
72      * audio driver:
73        - the ALSA audio output driver parameters now reflect the correct
74          parameter value ranges for the respective selected sound card
75          (patch by Till Wimmer, a bit fixed and extended)

85        - EG fix: a release value of zero could cause noises or crash
86        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
87        - EG fine tuning: when attack is zero the EG starts at a level
88          above max sustain level, which means that there is a decay phase
89          even if sustain is 100%
90        - more EG fixes: the level could sometimes go below zero and cause
91          noises or crashes
92        - minor fix of EGDecay (patch by Toshi Nagata)
93        - fixed compiler error when --enable-override-filter-type was
94          supplied to the configure script (fixes #46)
95        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
96          instead of a fix value
97    
98      * LSCP server:
99        - fixed compile time error for old Bison versions
100          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
101        - parser now supports extended ASCII character set
102          (up to ASCII code 255, i.e. includes now umlauts and accents)
103        - filename arguments in LSCP commands now allow to use escape
104          sequences, that is directly literal as one of: \', \", \\, \n, \r,
105          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
106          code value like \xf2) (fixes bug #24)
107        - returns verbose syntax errors (line and column where syntax error
108          occured, the unexpected character and the actually expected, possible
109          character(s), the latter only if less than 5 possibilities)
110    
111    * Bug fixes:    * Bug fixes:
112      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
113      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
114        channel audio output device"        channel audio output device"
115        - fixed a crash which occurs when reassigning the same engine
116          on a sampler channel with connected MIDI device
117        - fixed a crash which occurs when changing the number of ports of a MIDI
118          device connected to a sampler channel to number less then or equal
119          to the index of the port to which the sampler channel is connected.
120        - The previous bindings were not been disconnected when altering
121          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
122          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
123        - The active stream/voice count statistic was incorrect.
124        - notification events were not been sent for some sampler
125          channel changes
126        - added default min and max values to restrict the number of allowed
127          audio output channels and MIDI input ports
128        - the connection to the PCM interface is now closed when destroying
129          an audio output device
130        - files with slash in their path or filename could not be loaded
131    
132      * test cases:
133        - updated and fixed (haven't been touched in a while)
