3      * packaging changes:
4        - added autoconf checks for pthread library
5        - added autoconf check for pthread bug found on certain NPTL-enabled
6          glibc versions (see Gentoo bug report #194076)
7    
8      * general changes:
9        - bugfix: the thread used by an editor plugin didn't die when the
10          editor closed
11    
12      * LSCP server:
13        - added support for Windows style path / filenames, however with
14          forward slash path separators instead of backslash
15          (i.e. "C:/foo/bar.gig")
16    
17    Version 0.5.0 (15 October 2007)
18    
19      * packaging changes:
20        - config.h is not going to be installed along with liblinuxsampler's
21          API header files anymore
22        - only the API relevant header (and source) files will be exported to
23          the Doxygen API documentation (explicitly listed in Doxyfile.in)
24        - added completely new XCode project files for Mac OSX which is now
25          capable to execute our autoconf environment, thus no need anymore
26          to maintain the compile time configuration file (osx/version.h) for
27          OSX manually (patch by Toshi Nagata)
28        - fixed buggy boolean --enable-foo / --disable-foo configure script
29          parameters
30        - global.h now only covers global definitions that are needed for the
31          C++ API header files, all implementation internal global definitions
32          are now in global_private.h
33        - atomic.h is not exposed to the C++ API anymore
34        - no need to include config.h anymore for using LS's API header files
35        - fixed warnings in API doc generation

62        controllers        controllers
63      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
64        - Implemented new, improved notification system
65        - fixed compilation errors regarding OSX
66          (patch by Toshi Nagata)
67        - implemented instruments database
68        - added support for escape sequences to the instruments database
69        - added highly experimental support for on-the-fly instrument editing
70          within the sampler's process (by using instrument editor plugins),
71          you'll notice the new "Registered instrument editors:" message on
72          startup, added a new LSCP command:
73          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
74          to spawn a matching instrument editor for the instrument on the
75          given sampler channel, the plugin path can be overridden at compile
76          time with ./configure --enable-plugin-dir=/some/dir
77        - added experimental code for synchronizing instrument editors hosted
78          in the sampler's process to safely edit instruments while playing
79          without a crash (hopefully) by either suspending single regions
80          wherever possible or if unavoidable whole engine(s)
81        - fixed several issues in fundamental "Thread" class: set scheduling
82          policy and priority on thread level, set a minimum stack size for
83          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
84          threads simply inherited properties of starting thread instead of
85          setting their own policy and priority
86        - minor fix in our automatic stack trace mechanism on crashes, the
87          main process did not wait for the stack trace process to finish
88          its output
89        - fixed some minor memory leaks
90        - reenabled assembly features support, at the moment only for
91          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
92        - minor assembly fix in x86 features detection (don't use the PIC
93          register, to avoid relocations in the text segment at runtime)
94        - POSIX callback functions of Thread.h are hidden
95    
96    * MIDI driver:    * MIDI driver:
97      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
98    
99      * audio driver:
100        - the ALSA audio output driver parameters now reflect the correct
101          parameter value ranges for the respective selected sound card
102          (patch by Till Wimmer, a bit fixed and extended)
103

112        - EG fix: a release value of zero could cause noises or crash
113        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
114        - EG fine tuning: when attack is zero the EG starts at a level
115          above max sustain level, which means that there is a decay phase
116          even if sustain is 100%
117        - more EG fixes: the level could sometimes go below zero and cause
118          noises or crashes
119        - minor fix of EGDecay (patch by Toshi Nagata)
120        - fixed compiler error when --enable-override-filter-type was
121          supplied to the configure script (fixes #46)
122        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
123          instead of a fix value
124        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
125          127 (solo mode) only kill voices if the respective mode really
126          changed
127    
128      * LSCP server:
129        - fixed compile time error for old Bison versions
130          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
131        - parser now supports extended ASCII character set
132          (up to ASCII code 255, i.e. includes now umlauts and accents)
133        - filename arguments in LSCP commands now allow to use escape
134          sequences, that is directly literal as one of: \', \", \\, \n, \r,
135          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
136          code value like \xf2) (fixes bug #24)
137        - the following LSCP commands now also support escape sequences for at
138          least one of their text-based parameters (i.e. name, description):
139          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
140          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
141          "SET DB_INSTRUMENT_DIRECTORY NAME",
142          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
143          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
144          "FIND DB_INSTRUMENT_DIRECTORIES"
145        - returns verbose syntax errors (line and column where syntax error
146          occured, the unexpected character and the actually expected, possible
147          character(s), the latter only if less than 5 possibilities)
148        - made sure that LSCP syntax is not affected by gigedit locale
149          settings
150        - bugfix regarding strings parameter lists: all comma separated lists
151          of strings were treated as being one string containing commas
152          (fixes #57)
153    
154    * Bug fixes:    * Bug fixes:
155      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
156      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
157        channel audio output device"        channel audio output device"
158        - fixed a crash which occurs when reassigning the same engine
159          on a sampler channel with connected MIDI device
160        - fixed a crash which occurs when changing the number of ports of a MIDI
161          device connected to a sampler channel to number less then or equal
162          to the index of the port to which the sampler channel is connected.
163        - The previous bindings were not been disconnected when altering
164          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
165          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
166        - The active stream/voice count statistic was incorrect.
167        - notification events were not been sent for some sampler
168          channel changes
169        - added default min and max values to restrict the number of allowed
170          audio output channels and MIDI input ports
171        - the connection to the PCM interface is now closed when destroying
172          an audio output device
173        - files with slash in their path or filename could not be loaded
174    
175      * test cases:
176        - updated and fixed (haven't been touched in a while)
