3    * packaging changes:    * 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        - bugfix: Ringbuffer.h:
12          fill_write_space_with_null() did not zero out all the space
13          operator--() did not apply size_mask after decrementing the read_ptr
14          DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
15            the _NonVolatileReader functions.
16          
17    
18      * LSCP server:
19        - added support for Windows style path / filenames, however with
20          forward slash path separators instead of backslash
21          (i.e. "C:/foo/bar.gig")
22    
23    Version 0.5.0 (15 October 2007)
24    
25      * packaging changes:
26        - config.h is not going to be installed along with liblinuxsampler's
27          API header files anymore
28      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
29        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
30        - added completely new XCode project files for Mac OSX which is now
31          capable to execute our autoconf environment, thus no need anymore
32          to maintain the compile time configuration file (osx/version.h) for
33          OSX manually (patch by Toshi Nagata)
34        - fixed buggy boolean --enable-foo / --disable-foo configure script
35          parameters
36        - global.h now only covers global definitions that are needed for the
37          C++ API header files, all implementation internal global definitions
38          are now in global_private.h
39        - atomic.h is not exposed to the C++ API anymore
40        - no need to include config.h anymore for using LS's API header files

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

120      - EG fine tuning: when attack is zero the EG starts at a level      - EG fine tuning: when attack is zero the EG starts at a level
121        above max sustain level, which means that there is a decay phase        above max sustain level, which means that there is a decay phase
122        even if sustain is 100%        even if sustain is 100%
123        - more EG fixes: the level could sometimes go below zero and cause
124          noises or crashes
125        - minor fix of EGDecay (patch by Toshi Nagata)
126        - fixed compiler error when --enable-override-filter-type was
127          supplied to the configure script (fixes #46)
128        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
129          instead of a fix value
130        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
131          127 (solo mode) only kill voices if the respective mode really
132          changed
133    
134      * LSCP server:
135        - fixed compile time error for old Bison versions
136          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
137        - parser now supports extended ASCII character set
138          (up to ASCII code 255, i.e. includes now umlauts and accents)
139        - filename arguments in LSCP commands now allow to use escape
140          sequences, that is directly literal as one of: \', \", \\, \n, \r,
141          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
142          code value like \xf2) (fixes bug #24)
143        - the following LSCP commands now also support escape sequences for at
144          least one of their text-based parameters (i.e. name, description):
145          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
146          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
147          "SET DB_INSTRUMENT_DIRECTORY NAME",
148          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
149          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
150          "FIND DB_INSTRUMENT_DIRECTORIES"
151        - returns verbose syntax errors (line and column where syntax error
152          occured, the unexpected character and the actually expected, possible
153          character(s), the latter only if less than 5 possibilities)
154        - made sure that LSCP syntax is not affected by gigedit locale
155          settings
156        - bugfix regarding strings parameter lists: all comma separated lists
157          of strings were treated as being one string containing commas
158          (fixes #57)
159    
160    * Bug fixes:    * Bug fixes:
161      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
162      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
163        channel audio output device"        channel audio output device"
164        - fixed a crash which occurs when reassigning the same engine
165          on a sampler channel with connected MIDI device
166        - fixed a crash which occurs when changing the number of ports of a MIDI
167          device connected to a sampler channel to number less then or equal
168          to the index of the port to which the sampler channel is connected.
169        - The previous bindings were not been disconnected when altering
170          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
171          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
172        - The active stream/voice count statistic was incorrect.
173        - notification events were not been sent for some sampler
174          channel changes
175        - added default min and max values to restrict the number of allowed
176          audio output channels and MIDI input ports
177        - the connection to the PCM interface is now closed when destroying
178          an audio output device
179        - files with slash in their path or filename could not be loaded
180    
181      * test cases:
182        - updated and fixed (haven't been touched in a while)
