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         - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
17           since this function is currently only used in the stream's
18           qsort() compare function, it didn't trigger any bugs
19         Resampler.h, Synthesizer.h:
20           cubic interpolation now works in 24bit mode too
21           faster method to read 24bit words on little endian machines (x86):
22           replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
23    
24      * MIDI driver:
25        - added MME Windows MIDI driver
26    
27      * LSCP server:
28        - added support for Windows style path / filenames, however with
29          forward slash path separators instead of backslash
30          (i.e. "C:/foo/bar.gig")
31        - allow naughty liblscp to send non-string device parameters within
32          apostrophes as well
33    
34    Version 0.5.0 (15 October 2007)

45        - fixed buggy boolean --enable-foo / --disable-foo configure script
46          parameters
47        - global.h now only covers global definitions that are needed for the
48          C++ API header files, all implementation internal global definitions
49          are now in global_private.h
50        - atomic.h is not exposed to the C++ API anymore

93        time with ./configure --enable-plugin-dir=/some/dir        time with ./configure --enable-plugin-dir=/some/dir
94        - added experimental code for synchronizing instrument editors hosted
95          in the sampler's process to safely edit instruments while playing
96          without a crash (hopefully) by either suspending single regions
97          wherever possible or if unavoidable whole engine(s)
98        - fixed several issues in fundamental "Thread" class: set scheduling
99          policy and priority on thread level, set a minimum stack size for
100          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
101          threads simply inherited properties of starting thread instead of
102          setting their own policy and priority
103        - minor fix in our automatic stack trace mechanism on crashes, the
104          main process did not wait for the stack trace process to finish
105          its output
106        - fixed some minor memory leaks
107        - reenabled assembly features support, at the moment only for
108          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
109        - minor assembly fix in x86 features detection (don't use the PIC
110          register, to avoid relocations in the text segment at runtime)
111        - POSIX callback functions of Thread.h are hidden

139        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
140          instead of a fix value
141        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
142          127 (solo mode) only kill voices if the respective mode really
143          changed
144    
145      * LSCP server:
146        - fixed compile time error for old Bison versions
147          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
148        - parser now supports extended ASCII character set
149          (up to ASCII code 255, i.e. includes now umlauts and accents)
150        - filename arguments in LSCP commands now allow to use escape
151          sequences, that is directly literal as one of: \', \", \\, \n, \r,
152          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
153          code value like \xf2) (fixes bug #24)
154        - the following LSCP commands now also support escape sequences for at
155          least one of their text-based parameters (i.e. name, description):
156          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
157          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
158          "SET DB_INSTRUMENT_DIRECTORY NAME",
159          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
160          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
161          "FIND DB_INSTRUMENT_DIRECTORIES"
162        - returns verbose syntax errors (line and column where syntax error
163          occured, the unexpected character and the actually expected, possible
164          character(s), the latter only if less than 5 possibilities)
165        - made sure that LSCP syntax is not affected by gigedit locale
166          settings
167        - bugfix regarding strings parameter lists: all comma separated lists
168          of strings were treated as being one string containing commas
169          (fixes #57)
170    
171    * Bug fixes:    * Bug fixes:
172      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
173      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
174        channel audio output device"        channel audio output device"
175        - fixed a crash which occurs when reassigning the same engine
176          on a sampler channel with connected MIDI device
177        - fixed a crash which occurs when changing the number of ports of a MIDI
178          device connected to a sampler channel to number less then or equal
179          to the index of the port to which the sampler channel is connected.
180        - The previous bindings were not been disconnected when altering
181          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
182          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
183        - The active stream/voice count statistic was incorrect.
184        - notification events were not been sent for some sampler
185          channel changes
186        - added default min and max values to restrict the number of allowed
187          audio output channels and MIDI input ports
188        - the connection to the PCM interface is now closed when destroying
189          an audio output device
190        - files with slash in their path or filename could not be loaded
191
