4 ----------------------------------------------
5 0.2.17 (to be announced) "isotropic threshold"
6 ----------------------------------------------
7
8 Only bugfixes and cleanups in this version which marks the end of
9 the 0.2.x series if no serious bugs show up after the release.
10
11 - mysql_selector: fix a locking bug.
12 - be more carful wrt. signed vs. unsigned argument passing.
13 - cleanup error.h and fix some references to invalid error
14 codes.
15 - update to gengetopt-2.20.
16 - autoconf: extend checks for headers, library functions and
17 compiler characteristics.
18
19 --------------------------------------
20 0.2.16 (2007-04-05) "neural discharge"
21 --------------------------------------
22
23 The main change in this release is the major audio format handler
24 cleanup which removes some similar/duplicate code and makes it easier
25 to implement plugins for other audio formats. Of course, the usual mix
26 of other improvements/changes/bugfixes also made it into the release.
27
28 - simplified audio format handlers (most of the handling functions
29 were moved one layer up to the virtual streaming system).
30 - para_server uses mmap to read audio files
31 - repositioning of mp3 streams is much faster, in particular for
32 jumping near the end of large mp3 files.
33 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
34 and AFS_WRITE.
35 - fix a bug in para_filter that caused decoding of aac files
36 to start only after a few seconds.
37 - fix osx_writer hangs
38 - simplified dccp code (thanks to Gerrit Renker)
39 - the compress filter works also on big endian systems (ppc)
40
41 -----------------------------------------
42 0.2.15 (2007-02-16) "inductive resonance"
43 -----------------------------------------
44
45 Minor improvements, more documentation and a bunch of bug fixes.
46
47 - para_server: The server.users file is only read once on server
48 startup rather than for each connection
49 - mp3dec: Fix decoding of corrupt mp3 files
50 - afs (audio file sender) is now called vss (virtual streaming
51 system). Consequently, the permission flags specified in
52 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
53 become VSS_READ and VSS_WRITE respectively.
54 - para_audiod/para_filter: Fix a bug that caused the last chunk
55 of audio data not being written under certain circumstances
56 - audiod: compute the difference of server time and local time
57 correctly
58 - para_server/para_audiod: Fix some memory leaks
59 - documentation improvements
60 - configure.ac: fix checks for para_krell
61 - new man pages
62
63 -------------------------------------------
64 0.2.14 (2006-10-15) "transient singularity"
65 -------------------------------------------
66
67 The only major enhancement of this version is the osx writer which completes
68 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
69 until now for reasons beyond the scope of this changelog entry.
70
71 - new output plugin for Mac Os: the osx writer
72 - rename configure command line options from --enable-xxx-headers to
73 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
74 - configure: new command line options: --with-mad-headers,
75 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
76 - some robustness fixes
77 - dymamic audio format recognition for audiod
78 - para_server: new command line option: --autoplay_delay
79 - para_audiod: new command line option: --clock_diff_count
80
81 ---------------------------------------
82 0.2.13 (2006-07-14) "sonic convolution"
83 ---------------------------------------
84
85 A bunch of new features and core changes.
86
87 - the new paraslash scheduler, short and sweet.
88 - Support for m4a/mp4 files via the new aac audio format
89 handler/filter (requires libfaad).
90 - each writer has its own command line parser, just like
91 para_recv and para_filter.
92 - para_client and para_audioc use the error subsystem
93 - writers are integrated in para_audiod (currently linux-only)
94 - para_client is integrated in para_audiod
95 - random/playlist selector: improved info strings
96 - new audiod commands: tasks, kill
97 - update to libortp-0.10.1
98 - para_fade: wake time defaults to 8 hours from now
99 - update to autoconf-2.60
100
101
102 ------------------------------------------
103 0.2.12 (2006-05-12) "oriented abstraction"
104 ------------------------------------------
105
106 Many user-visible changes in this release and lots of new
107 features:
108
109
110 - the new optional dccp sender/receiver. It uses the datagram
111 congestion control protocol. You'll need a fairly new kernel
112 for this.
113 - paraslash works on Mac OS X (thanks to Gerd Becker)
114 - para_play renamed to para_write
115 - modular output plugin design (writers) for para_write
116 - new file_writer output plugin for para_write
117 - compress filter speed improvements
118 - update to libortp-0.9.1
119 - update to gengetopt-2.17rc
120 - para_client no longer depends on libreadline (as the
121 code for the interactive mode was removed).
122 - gcc-2-95 is no longer a supported compiler. It may still
123 work, but it gets no more testing.
124 - the tarball no longer contains the screenshot images which
125 reduces its size quite a bit.
126 - configure: new command line options: --enable-mysql-headers
127 and --enable-mysql-libs
128
129 ------------------------------------
130 0.2.11 (2006-03-11) "atomic duality"
131 ------------------------------------
132
133 Here it is, the first paraslash release developed with git. There
134 are fairly many user-visible changes in this release. As two out of
135 the three "database tools" of paraslash don't use a database at all,
136 they are now called "audio file selectors" instead.
137
138
139 - the cdt command (change database tool) becomes chs (change
140 selector)
141 - no more colon separators: The syntax of some options of
142 para_audiod and para_filter have changed. Use --help for
143 more info (and some examples).
144 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
145 - switch from cvs to git (should've done that earlier)
146 - the new ipc subsystem
147 - new audio file selector: playlist
148 - para_server: the dopey selector is now called "random",
149 and is the default selector. Use the --selector option to
150 choose another selector at startup, or the chs command to
151 change the selector at runtime.
152 - X86_64 fixes (thanks to Steffen Klassert)
153 - para_play fixes
154
155
156 --------------------------------------
157 0.2.10 (2006-02-17) "cyclic attractor"
158 --------------------------------------
159
160 Huge documentation update, a scrollable window for para_gui, ortp
161 improvements, and of course many small fixes not mentioned here.
162 The diffstat below is rather misleading as most insertions are due
163 to the new source documentation.
164
165 - autoconf cleanup
166 - para_server also uses the new error subsystem
167 - lots of new documentation (UTSL)
168 - gui improvements:
169 - keysyms for cursor keys and for next/previous page keys
170 - scrollable output window
171 - new internal commands: scroll up/down, page up/down
172 - fix color of command output.
173 - ortp: the --chunk_time and --header flags are no longer needed
174 for para_recv/para_audiod as this information is now encoded in
175 each rtp packet sent by para_server.
176
177
178 -------------------------------------------
179 0.2.9 (2006-01-24) "progressive turbulence"
180 -------------------------------------------
181
182 Internal audiod receivers/filters, the new error subsystem and
183 a lot of small improvements.
184
185 - para_recv and para_filter are integrated into the para_audiod
186 binary, i.e. audiod no longer spawns a new process for
187 each receiver/filter. As para_recv and para_filter might be
188 useful as standalone programs, they still get built (linked
189 against the same object files that are also used for audiod).
190 - further ortp timing improvements should reduce the CPU usage
191 of the ortp receiver.
192 - improved audio grabbing. The 'grab' command of para_audiod
193 has its own set of command line options. Read the output of
194 "para_audioc help grab" for more info.
195 - oggdec: configurable input prebuffer size.
196 - the new error subsystem gives better error diagnostics
197 and reduces code size.
198
199
200 -----------------------------------------
201 0.2.8 (2006-01-02) "dynamic accumulation"
202 -----------------------------------------
203
204 The new modular filter design and the para_play-hangs bugfix.
205
206 - new executable: para_filter. It combines para_mp3dec,
207 para_oggdec and para_compress. It also adds a further filter
208 type, wav, that just inserts a wave header at the desired point
209 of the filter chain. All 'piping' is done in-memory (i.e. no
210 read/write operations are used).
211 - para_play: fix a stupid bug that caused it to hang under
212 certain circumstances.
213
214
215 -------------------------------------------
216 0.2.7 (2006-12-27) "transparent invariance"
217 -------------------------------------------
218
219 Not many user-visible changes but a fair amount of internal improvements.
220
221
222 - The http sender buffers data if it can not be sent
223 out immediately (because the socket is not writable). This
224 should prevent para_server from shutting down the connection
225 too early on a loaded network.
226 - para_play also prebuffers data if it is told to start at a
227 future time by the --start_time option.
228 - The return of para_recv: It combines para_ortp_recv and
229 para_http_recv. Use the --receiver option to switch between
230 the two. para_recv builds without libortp, but contains
231 only the http receiver in this case.
232 - update to ortp 0.8.1. As this ortp release contains incompatible
233 changes, para_recv-0.2.7 won't link against older ortp libs.
234 - improved ortp timings.
235 - use of gcc-extensions that #define away for non-gcc and
236 gcc < 3.0.
237
238
239 -------------------------------------------
240 0.2.6 (2005-10-29) "recursive compensation"
241 -------------------------------------------
242
243 Transparent session encryption (uses openssl's Alleged RC4 cipher),
244 the internal find command and several other improvements and cleanups.
245
246 - Encrypt the session if encryption is requested by the client
247 (default for para_client 0.2.6). This is backwards
248 compatible, so older clients can still connect to para_server
249 0.2.6. Use the new client option --plain to request an
250 uncrypted session (off by default, must be set to on in
251 order to connect to para_server 0.2.x with 0 <= x <= 5).
252 - para_server uses an internal function to locate audio files
253 rather than calling find(1). The server option
254 --mysql_audio_file_dir replaces --mysql_find_cmd.
255 - documentation update
256 - man pages
257 - header file cleanup
258 - para_client code cleanup
259 - para_gui: faster display of output of display commands
260
261
262 ------------------------------------------
263 0.2.5 (2005-10-13) "aggressive resolution"
264 ------------------------------------------
265
266 This release adds internal senders, i.e. no more external programs are
267 spawned for sending out the audio data. There are two different senders
268 available: The http sender and the ortp sender (former para_send which
269 is no longer needed).
270
271 The new sender code has a plugin-like design so it can be easily
272 extended should there be be any future need for supporting another
273 network streaming protocol. All senders are completely independent of
274 each other. In particular, the http and the ortp sender can operate
275 in parallel.
276
277 - new server command: sender to control senders at runtime.
278 Read the output of "para_server -h" and "para_client help
279 sender" for more information.
280 - para_recv renamed to para_ortp_recv
281 - new executable: para_http_recv, a simple command line
282 http receiver.
283 - major afs/mp3/ogg code simplifications due to internal
284 senders.
285 - ogg timing improvements
286 - fix several minor memory leaks (found by valgrind)
287 - empty stream definitions work again
288 - com_ne(): ignore errors on remove
289 - audiod: fix segfault on server restart
290
291
292 ---------------------------------------
293 0.2.4 (2005-09-21) "toxic anticipation"
294 ---------------------------------------
295
296 Several small improvements, fixes and the new grab command.
297
298 - audiod:
299 - new command: "grab" to grab the output of the stream reader
300 or any filters. Read the output of "para_audioc help grab"
301 for more information.
302 - fix memory leak
303 - code cleanup
304 - audioc: new command line option: --bufsize to specify a
305 buffer size different from the default size 8192.
306 - improved error diagnostics for para_play.
307 - new configure option: --enable-ssldir so search for openssl in
308 non-standard places
309 - sdl_gui: Make it look nice again for 1024x768
310 - server: report total size of memory allocated with sbrk by malloc,
311 new command line option: --announce_time
312
313
314 -----------------------------------------
315 0.2.3 (2005-09-01) "hydrophilic movement"
316 -----------------------------------------
317
318 Two new executables and major feature enhancements.
319
320 - audiod filters: It is now possible to specify arbitrary many
321 (including none) filters for each supported audio
322 format. This can be used e.g. for normalizing volume,
323 transforming or grabbing the audio stream, or for using
324 visualizers. Read the output of "para_audiod -h" for the
325 syntax of the new --filter_cmd option.
326 - new executable: para_play, a tiny alsa player. It
327 can play wave files or raw pcm (16 bit little endian)
328 from stdin.
329 - new executable: para_compress, a dynamic range compressor
330 intended to keep audio output at a consistent volume. Derived
331 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
332 - audiod: New option: --stream_delay. This can be used in
333 a local network to syncronize the audio output of all
334 clients that play the same stream.
335
336
337 ------------------------------------------
338 0.2.2 (2005-08-19) "tangential excitation"
339 ------------------------------------------
340
341 Mostly internal changes in this release, but also some new commands
342 for the mysql database tool.
343
344 - cleanup exec.c, fix para_exec bug
345 - compile time loglevel (log messages below the given level
346 won't be compiled in, which reduces the size of the
347 resulting binaries)
348 - new log macros that shorten the size of the source code.
349 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
350 to send only zeros. With this workaround, para_audioc works
351 again.
352 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
353 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
354 (new entry), "snp" (set numplayed). Read the manual for more
355 information.
356
357
358 ---------------------------------------
359 0.2.1 (2005-08-15) "surreal experience"
360 ---------------------------------------
361
362 Here comes paraslash-0.2.1. It contains a couple of new features and,
363 surprise, only minor bug fixes.
364
365 - kill noisy mp3 debug message
366 - cleanup of the build system
367 - para_server and para_client directly use the crypto routines
368 of the openssl library rather than invoking the openssl command
369 line utitlity
370 - server/audiod: new option --user to switch to the given user
371 when invoked as root. Read the output of "para_server -h" for
372 more information.
373 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
374 status. Default: "para_audioc stat"
375 - sdl_gui: new option --pic_cmd to be used to download the picture.
376 Default: "para_client pic"
377 - audiod: 5 slots ought to be enough for everybody
378 - audiod: new status item: Uptime, kill hup command
379
380
381
382 ------------------------------------------
383 0.2.0 (2005-08-06) "distributed diffusion"
384 ------------------------------------------
385
386 After several month of increased development activity, paraslash-0.2.0
387 has arrived. It contains many new features and is much more
388 self-contained than the old 0.1.x series. Enjoy!
389
390
391 - para_server: fix hang on song change and crash on sighup.
392 Speed up mysql queries. The DIR_LIKE macro is gone.
393 - new executables: para_audiod, the local audio daemon that
394 starts playback (uses SCM_CREDENTIALS socket magic) and
395 para_audioc, the corresponding client.
396 - new executables: para_mp3dec/para_oggdec, two really teensy
397 decoders. para_mp3dec is based on libmad, para_oggdec requires
398 libvorbisfile.
399 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
400 they are now called para_send and para_recv respectively.
401 - documentation updates
402 - para_gui is themable. For now there is the default theme that
403 looks as before and the simple theme: blue and easy.
404 - gui: audio streaming is now handled by audiod. Time display shows
405 playback time rather than streaming time
406 - slider: update to libzmw-0.2.0
407 - para_krell: fix crash on server shutdown
408 - switch from gzip to bzip2
409
410
411 ----------------------------------------
412 0.1.7 (2005-04-18) "melting penetration"
413 ----------------------------------------
414
415 The main change in this release is clearly the oggvorbis rewrite,
416 but there are also lots of smaller changes. If you intend to use both
417 the mp3 and the ogg plugin, it is recommended to use software mixing,
418 e.g. the dmix plugin which is provided by ALSA.
419
420 - new executables: para_ovsend and para_ovrecv for sending/receiving
421 oggvorbis files via rtp. Requires the open rtp library. Get it at
422 http://www.linphone.org/ortp/
423 - rewrite of the ogg_vorbis core code
424 - configure detects libzmw and, if detected, includes
425 para_slider to the list of binaries to be built by make
426 - server stream writers read from their associated fifo rather
427 than from stdin
428 - slider: two new sliders, lastplayed and numplayed
429 - fix nasty double free bug which caused random segfaults in case of
430 mp3 files with invalid header information
431 - gui: new command line option: --stream_timeout=seconds to
432 deactivate a slot if it is idle for that many seconds (default=`5')
433 - diffstats
434
435
436 ---------------------------------------
437 0.1.6 (2005-03-05) "asymptotic balance"
438 ---------------------------------------
439
440 Only little user-visible changes in this release. Mainly bugfixes and
441 core code cleanup. This is probably the most stable version ever if you
442 stick to mp3...
443
444 - fix several memory leaks
445 - rename default name of mysql database from "music" to "paraslash".
446 Use para_server's --mysql_database option if you do not want to
447 rename your old database.
448 - rework ogg vorbis code
449 - make update command work on mysql servers with LOCAL_INFILE
450 disabled
451 - gui: improved stream I/O (slots)
452 - simplified audio format API
453 - para_pob_ogg is gone
454
455 ------------------------------------
456 0.1.5 (2004-12-31) "opaque eternity"
457 ------------------------------------
458
459 Let's slide gently into the new year.
460
461 - new: para_slider (not built automatically, type "make
462 para_slider" to build). A toy for those who always felt that
463 creating stream definitions is difficult. See screenshots,
464 README and FEATURES for more info.
465 - improved signal handling. Fixes server segfault on SIGHUP
466 for linux kernels newer than Aug 24 2004 and makes para_gui
467 race-free.
468 - reload database tool on SIGHUP
469 - improved help message for sl
470 - do not log "broken pipe" messages as errors. They are
471 perfectly ok.
472 - fix wrong error message on permission errors
473
474 -----------------------------------------
475 0.1.4 (2004-12-19) "tunneling transition"
476 -----------------------------------------
477
478 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
479 Hopefully, most of them got wiped out with this release. Some
480 enhancements went also in.
481
482 - improved error diagnostics for all commands
483 - stradd/picadd: overwrite previous contents if entry already
484 exists, rather than returning errors
485 - stradd: use current stream if invoked without args
486 - faster (and hopefully more stable) ogg-vorbis handling
487 - para_krell: reap children to avoid zombie-flooding in case
488 no server is running
489 - si: report also server pid
490 - server: don't busy-loop if dbtool reports only invalid files.
491 - gui: CTRL+C works again, fix stream_read command line option
492 - fix pic_add, hist
493 - fix mysql dbtool startup in case no database exists
494 - many small fixes and cleanups
495
496 ---------------------------------------
497 0.1.3: (2004-12-10) "vanishing inertia"
498 ---------------------------------------
499
500 Starting from this release, the database tools are integrated in the
501 server binary. This decreases server startup time, reduces code size
502 and speeds up database commands. However, the layout of the underlying
503 mysql database changed only slightly and 0.1.3 should be backwards
504 compatible in that respect.
505
506 Visible changes:
507
508 - If mysql is not detected at compile time, or fails to init
509 at runtime, fall back to the dopey database tool which should
510 always work.
511 - para_dbtool and dbtool.conf are gone. All mysql specific
512 options are read from server.conf and are prefixed by 'mysql_'.
513 - new command: cdt (change database tool)
514 - new command line option: dbtool (choose startup database tool)
515 - The name of current stream is now stored in the database,
516 so paraslash remembers its current stream when restarted.
517 - new command: csp (change stream and play)
518 - para_gui also reports current database tool and server uptime
519
520
521 -------------------------------------------
522 0.1.2: (2004-11-28) "spherical fluctuation"
523 -------------------------------------------
524
525 Point release before the big dbtool changes go in.
526
527 - dbtool: rename ca to cam (copy all meta data). It now also
528 copies numplayed and lastplayed time as well as the picture
529 id.
530 - fix endless-loop-bug caused by mp3 files with invalid header
531
532 -----------------------------------------
533 0.1.1: (2004-11-05) "floating atmosphere"
534 -----------------------------------------
535
536 - gkrellm plugin
537 - new dbtool command: mbox. Browse your sound-file collection
538 with your favorite mail reader.
539 - several small fixes
540
541 -------------------------------------
542 0.1.0: (2204-10-22) "rotating cortex"
543 -------------------------------------
544
