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        - added autoconf checks for MS Windows
8    
9      * general changes:
10        - bugfix: the thread used by an editor plugin didn't die when the
11          editor closed
12        - bugfix: Ringbuffer.h:
13          fill_write_space_with_null() did not zero out all the space
14          operator--() did not apply size_mask after decrementing the read_ptr
15          DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
16            the _NonVolatileReader functions.
17         - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
18           since this function is currently only used in the stream's
19           qsort() compare function, it didn't trigger any bugs
20         Resampler.h, Synthesizer.h:
21           cubic interpolation now works in 24bit mode too
22           faster method to read 24bit words on little endian machines (x86):
23           replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
24         Experimental support for MS Windows (MIDI input via MME, AUDIO output via ASIO)
25    
26      * AUDIO driver:
27        - added Windows ASIO low latency audio driver
28    
29      * MIDI driver:
30        - added MME Windows MIDI driver
31    
32      * LSCP server:
33        - added support for Windows style path / filenames, however with
34          forward slash path separators instead of backslash
35          (i.e. "C:/foo/bar.gig")
36        - allow naughty liblscp to send non-string device parameters within
37          apostrophes as well
38        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
39          "LIST FILE INSTRUMENTS <file>" and
40          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
41          about an arbitrary instrument file on the system where the sampler is
42          running on
43    
44    Version 0.5.0 (15 October 2007)

55        - fixed buggy boolean --enable-foo / --disable-foo configure script
56          parameters
57        - global.h now only covers global definitions that are needed for the
58          C++ API header files, all implementation internal global definitions
59          are now in global_private.h
60        - atomic.h is not exposed to the C++ API anymore

103        time with ./configure --enable-plugin-dir=/some/dir        time with ./configure --enable-plugin-dir=/some/dir
104        - added experimental code for synchronizing instrument editors hosted
105          in the sampler's process to safely edit instruments while playing
106          without a crash (hopefully) by either suspending single regions
107          wherever possible or if unavoidable whole engine(s)
108        - fixed several issues in fundamental "Thread" class: set scheduling
109          policy and priority on thread level, set a minimum stack size for
110          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
111          threads simply inherited properties of starting thread instead of
112          setting their own policy and priority
113        - minor fix in our automatic stack trace mechanism on crashes, the
114          main process did not wait for the stack trace process to finish
115          its output
116        - fixed some minor memory leaks
117        - reenabled assembly features support, at the moment only for
118          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
119        - minor assembly fix in x86 features detection (don't use the PIC
120          register, to avoid relocations in the text segment at runtime)
121        - POSIX callback functions of Thread.h are hidden
122

149        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
150          instead of a fix value
151        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
152          127 (solo mode) only kill voices if the respective mode really
153          changed
154    
155      * LSCP server:
156        - fixed compile time error for old Bison versions
157          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
158        - parser now supports extended ASCII character set
159          (up to ASCII code 255, i.e. includes now umlauts and accents)
160        - filename arguments in LSCP commands now allow to use escape
161          sequences, that is directly literal as one of: \', \", \\, \n, \r,
162          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
163          code value like \xf2) (fixes bug #24)
164        - the following LSCP commands now also support escape sequences for at
165          least one of their text-based parameters (i.e. name, description):
166          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
167          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
168          "SET DB_INSTRUMENT_DIRECTORY NAME",
169          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
170          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
171          "FIND DB_INSTRUMENT_DIRECTORIES"
172        - returns verbose syntax errors (line and column where syntax error
173          occured, the unexpected character and the actually expected, possible
174          character(s), the latter only if less than 5 possibilities)
175        - made sure that LSCP syntax is not affected by gigedit locale
176          settings
177        - bugfix regarding strings parameter lists: all comma separated lists
178          of strings were treated as being one string containing commas
179          (fixes #57)
180    
181    * Bug fixes:    * Bug fixes:
182      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
183      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
184        channel audio output device"        channel audio output device"
185        - fixed a crash which occurs when reassigning the same engine
186          on a sampler channel with connected MIDI device
187        - fixed a crash which occurs when changing the number of ports of a MIDI
188          device connected to a sampler channel to number less then or equal
189          to the index of the port to which the sampler channel is connected.
190        - The previous bindings were not been disconnected when altering
191          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
192          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
193        - The active stream/voice count statistic was incorrect.
194        - notification events were not been sent for some sampler
195          channel changes
196        - added default min and max values to restrict the number of allowed
197          audio output channels and MIDI input ports
198        - the connection to the PCM interface is now closed when destroying
199          an audio output device
200        - files with slash in their path or filename could not be loaded
201
