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 - be more carful wrt. signed vs. unsigned argument passing.
12 - cleanup error.h and fix some references to invalid error
13 codes.
14
15 --------------------------------------
16 0.2.16 (2007-04-05) "neural discharge"
17 --------------------------------------
18
19 The main change in this release is the major audio format handler
20 cleanup which removes some similar/duplicate code and makes it easier
21 to implement plugins for other audio formats. Of course, the usual mix
22 of other improvements/changes/bugfixes also made it into the release.
23
24 - simplified audio format handlers (most of the handling functions
25 were moved one layer up to the virtual streaming system).
26 - para_server uses mmap to read audio files
27 - repositioning of mp3 streams is much faster, in particular for
28 jumping near the end of large mp3 files.
29 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
30 and AFS_WRITE.
31 - fix a bug in para_filter that caused decoding of aac files
32 to start only after a few seconds.
33 - fix osx_writer hangs
34 - simplified dccp code (thanks to Gerrit Renker)
35 - the compress filter works also on big endian systems (ppc)
36
37 -----------------------------------------
38 0.2.15 (2007-02-16) "inductive resonance"
39 -----------------------------------------
40
41 Minor improvements, more documentation and a bunch of bug fixes.
42
43 - para_server: The server.users file is only read once on server
44 startup rather than for each connection
45 - mp3dec: Fix decoding of corrupt mp3 files
46 - afs (audio file sender) is now called vss (virtual streaming
47 system). Consequently, the permission flags specified in
48 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
49 become VSS_READ and VSS_WRITE respectively.
50 - para_audiod/para_filter: Fix a bug that caused the last chunk
51 of audio data not being written under certain circumstances
52 - audiod: compute the difference of server time and local time
53 correctly
54 - para_server/para_audiod: Fix some memory leaks
55 - documentation improvements
56 - configure.ac: fix checks for para_krell
57 - new man pages
58
59 -------------------------------------------
60 0.2.14 (2006-10-15) "transient singularity"
61 -------------------------------------------
62
63 The only major enhancement of this version is the osx writer which completes
64 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
65 until now for reasons beyond the scope of this changelog entry.
66
67 - new output plugin for Mac Os: the osx writer
68 - rename configure command line options from --enable-xxx-headers to
69 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
70 - configure: new command line options: --with-mad-headers,
71 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
72 - some robustness fixes
73 - dymamic audio format recognition for audiod
74 - para_server: new command line option: --autoplay_delay
75 - para_audiod: new command line option: --clock_diff_count
76
77 ---------------------------------------
78 0.2.13 (2006-07-14) "sonic convolution"
79 ---------------------------------------
80
81 A bunch of new features and core changes.
82
83 - the new paraslash scheduler, short and sweet.
84 - Support for m4a/mp4 files via the new aac audio format
85 handler/filter (requires libfaad).
86 - each writer has its own command line parser, just like
87 para_recv and para_filter.
88 - para_client and para_audioc use the error subsystem
89 - writers are integrated in para_audiod (currently linux-only)
90 - para_client is integrated in para_audiod
91 - random/playlist selector: improved info strings
92 - new audiod commands: tasks, kill
93 - update to libortp-0.10.1
94 - para_fade: wake time defaults to 8 hours from now
95 - update to autoconf-2.60
96
97
98 ------------------------------------------
99 0.2.12 (2006-05-12) "oriented abstraction"
100 ------------------------------------------
101
102 Many user-visible changes in this release and lots of new
103 features:
104
105
106 - the new optional dccp sender/receiver. It uses the datagram
107 congestion control protocol. You'll need a fairly new kernel
108 for this.
109 - paraslash works on Mac OS X (thanks to Gerd Becker)
110 - para_play renamed to para_write
111 - modular output plugin design (writers) for para_write
112 - new file_writer output plugin for para_write
113 - compress filter speed improvements
114 - update to libortp-0.9.1
115 - update to gengetopt-2.17rc
116 - para_client no longer depends on libreadline (as the
117 code for the interactive mode was removed).
118 - gcc-2-95 is no longer a supported compiler. It may still
119 work, but it gets no more testing.
120 - the tarball no longer contains the screenshot images which
121 reduces its size quite a bit.
122 - configure: new command line options: --enable-mysql-headers
123 and --enable-mysql-libs
124
125 ------------------------------------
126 0.2.11 (2006-03-11) "atomic duality"
127 ------------------------------------
128
129 Here it is, the first paraslash release developed with git. There
130 are fairly many user-visible changes in this release. As two out of
131 the three "database tools" of paraslash don't use a database at all,
132 they are now called "audio file selectors" instead.
133
134
135 - the cdt command (change database tool) becomes chs (change
136 selector)
137 - no more colon separators: The syntax of some options of
138 para_audiod and para_filter have changed. Use --help for
139 more info (and some examples).
140 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
141 - switch from cvs to git (should've done that earlier)
142 - the new ipc subsystem
143 - new audio file selector: playlist
144 - para_server: the dopey selector is now called "random",
145 and is the default selector. Use the --selector option to
146 choose another selector at startup, or the chs command to
147 change the selector at runtime.
148 - X86_64 fixes (thanks to Steffen Klassert)
149 - para_play fixes
150
151
152 --------------------------------------
153 0.2.10 (2006-02-17) "cyclic attractor"
154 --------------------------------------
155
156 Huge documentation update, a scrollable window for para_gui, ortp
157 improvements, and of course many small fixes not mentioned here.
158 The diffstat below is rather misleading as most insertions are due
159 to the new source documentation.
160
161 - autoconf cleanup
162 - para_server also uses the new error subsystem
163 - lots of new documentation (UTSL)
164 - gui improvements:
165 - keysyms for cursor keys and for next/previous page keys
166 - scrollable output window
167 - new internal commands: scroll up/down, page up/down
168 - fix color of command output.
169 - ortp: the --chunk_time and --header flags are no longer needed
170 for para_recv/para_audiod as this information is now encoded in
171 each rtp packet sent by para_server.
172
173
174 -------------------------------------------
175 0.2.9 (2006-01-24) "progressive turbulence"
176 -------------------------------------------
177
178 Internal audiod receivers/filters, the new error subsystem and
179 a lot of small improvements.
180
181 - para_recv and para_filter are integrated into the para_audiod
182 binary, i.e. audiod no longer spawns a new process for
183 each receiver/filter. As para_recv and para_filter might be
184 useful as standalone programs, they still get built (linked
185 against the same object files that are also used for audiod).
186 - further ortp timing improvements should reduce the CPU usage
187 of the ortp receiver.
188 - improved audio grabbing. The 'grab' command of para_audiod
189 has its own set of command line options. Read the output of
190 "para_audioc help grab" for more info.
191 - oggdec: configurable input prebuffer size.
192 - the new error subsystem gives better error diagnostics
193 and reduces code size.
194
195
196 -----------------------------------------
197 0.2.8 (2006-01-02) "dynamic accumulation"
198 -----------------------------------------
199
200 The new modular filter design and the para_play-hangs bugfix.
201
202 - new executable: para_filter. It combines para_mp3dec,
203 para_oggdec and para_compress. It also adds a further filter
204 type, wav, that just inserts a wave header at the desired point
205 of the filter chain. All 'piping' is done in-memory (i.e. no
206 read/write operations are used).
207 - para_play: fix a stupid bug that caused it to hang under
208 certain circumstances.
209
210
211 -------------------------------------------
212 0.2.7 (2006-12-27) "transparent invariance"
213 -------------------------------------------
214
215 Not many user-visible changes but a fair amount of internal improvements.
216
217
218 - The http sender buffers data if it can not be sent
219 out immediately (because the socket is not writable). This
220 should prevent para_server from shutting down the connection
221 too early on a loaded network.
222 - para_play also prebuffers data if it is told to start at a
223 future time by the --start_time option.
224 - The return of para_recv: It combines para_ortp_recv and
225 para_http_recv. Use the --receiver option to switch between
226 the two. para_recv builds without libortp, but contains
227 only the http receiver in this case.
228 - update to ortp 0.8.1. As this ortp release contains incompatible
229 changes, para_recv-0.2.7 won't link against older ortp libs.
230 - improved ortp timings.
231 - use of gcc-extensions that #define away for non-gcc and
232 gcc < 3.0.
233
234
235 -------------------------------------------
236 0.2.6 (2005-10-29) "recursive compensation"
237 -------------------------------------------
238
239 Transparent session encryption (uses openssl's Alleged RC4 cipher),
240 the internal find command and several other improvements and cleanups.
241
242 - Encrypt the session if encryption is requested by the client
243 (default for para_client 0.2.6). This is backwards
244 compatible, so older clients can still connect to para_server
245 0.2.6. Use the new client option --plain to request an
246 uncrypted session (off by default, must be set to on in
247 order to connect to para_server 0.2.x with 0 <= x <= 5).
248 - para_server uses an internal function to locate audio files
249 rather than calling find(1). The server option
250 --mysql_audio_file_dir replaces --mysql_find_cmd.
251 - documentation update
252 - man pages
253 - header file cleanup
254 - para_client code cleanup
255 - para_gui: faster display of output of display commands
256
257
258 ------------------------------------------
259 0.2.5 (2005-10-13) "aggressive resolution"
260 ------------------------------------------
261
262 This release adds internal senders, i.e. no more external programs are
263 spawned for sending out the audio data. There are two different senders
264 available: The http sender and the ortp sender (former para_send which
265 is no longer needed).
266
267 The new sender code has a plugin-like design so it can be easily
268 extended should there be be any future need for supporting another
269 network streaming protocol. All senders are completely independent of
270 each other. In particular, the http and the ortp sender can operate
271 in parallel.
272
273 - new server command: sender to control senders at runtime.
274 Read the output of "para_server -h" and "para_client help
275 sender" for more information.
276 - para_recv renamed to para_ortp_recv
277 - new executable: para_http_recv, a simple command line
278 http receiver.
279 - major afs/mp3/ogg code simplifications due to internal
280 senders.
281 - ogg timing improvements
282 - fix several minor memory leaks (found by valgrind)
283 - empty stream definitions work again
284 - com_ne(): ignore errors on remove
285 - audiod: fix segfault on server restart
286
287
288 ---------------------------------------
289 0.2.4 (2005-09-21) "toxic anticipation"
290 ---------------------------------------
291
292 Several small improvements, fixes and the new grab command.
293
294 - audiod:
295 - new command: "grab" to grab the output of the stream reader
296 or any filters. Read the output of "para_audioc help grab"
297 for more information.
298 - fix memory leak
299 - code cleanup
300 - audioc: new command line option: --bufsize to specify a
301 buffer size different from the default size 8192.
302 - improved error diagnostics for para_play.
303 - new configure option: --enable-ssldir so search for openssl in
304 non-standard places
305 - sdl_gui: Make it look nice again for 1024x768
306 - server: report total size of memory allocated with sbrk by malloc,
307 new command line option: --announce_time
308
309
310 -----------------------------------------
311 0.2.3 (2005-09-01) "hydrophilic movement"
312 -----------------------------------------
313
314 Two new executables and major feature enhancements.
315
316 - audiod filters: It is now possible to specify arbitrary many
317 (including none) filters for each supported audio
318 format. This can be used e.g. for normalizing volume,
319 transforming or grabbing the audio stream, or for using
320 visualizers. Read the output of "para_audiod -h" for the
321 syntax of the new --filter_cmd option.
322 - new executable: para_play, a tiny alsa player. It
323 can play wave files or raw pcm (16 bit little endian)
324 from stdin.
325 - new executable: para_compress, a dynamic range compressor
326 intended to keep audio output at a consistent volume. Derived
327 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
328 - audiod: New option: --stream_delay. This can be used in
329 a local network to syncronize the audio output of all
330 clients that play the same stream.
331
332
333 ------------------------------------------
334 0.2.2 (2005-08-19) "tangential excitation"
335 ------------------------------------------
336
337 Mostly internal changes in this release, but also some new commands
338 for the mysql database tool.
339
340 - cleanup exec.c, fix para_exec bug
341 - compile time loglevel (log messages below the given level
342 won't be compiled in, which reduces the size of the
343 resulting binaries)
344 - new log macros that shorten the size of the source code.
345 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
346 to send only zeros. With this workaround, para_audioc works
347 again.
348 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
349 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
350 (new entry), "snp" (set numplayed). Read the manual for more
351 information.
352
353
354 ---------------------------------------
355 0.2.1 (2005-08-15) "surreal experience"
356 ---------------------------------------
357
358 Here comes paraslash-0.2.1. It contains a couple of new features and,
359 surprise, only minor bug fixes.
360
361 - kill noisy mp3 debug message
362 - cleanup of the build system
363 - para_server and para_client directly use the crypto routines
364 of the openssl library rather than invoking the openssl command
365 line utitlity
366 - server/audiod: new option --user to switch to the given user
367 when invoked as root. Read the output of "para_server -h" for
368 more information.
369 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
370 status. Default: "para_audioc stat"
371 - sdl_gui: new option --pic_cmd to be used to download the picture.
372 Default: "para_client pic"
373 - audiod: 5 slots ought to be enough for everybody
374 - audiod: new status item: Uptime, kill hup command
375
376
377
378 ------------------------------------------
379 0.2.0 (2005-08-06) "distributed diffusion"
380 ------------------------------------------
381
382 After several month of increased development activity, paraslash-0.2.0
383 has arrived. It contains many new features and is much more
384 self-contained than the old 0.1.x series. Enjoy!
385
386
387 - para_server: fix hang on song change and crash on sighup.
388 Speed up mysql queries. The DIR_LIKE macro is gone.
389 - new executables: para_audiod, the local audio daemon that
390 starts playback (uses SCM_CREDENTIALS socket magic) and
391 para_audioc, the corresponding client.
392 - new executables: para_mp3dec/para_oggdec, two really teensy
393 decoders. para_mp3dec is based on libmad, para_oggdec requires
394 libvorbisfile.
395 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
396 they are now called para_send and para_recv respectively.
397 - documentation updates
398 - para_gui is themable. For now there is the default theme that
399 looks as before and the simple theme: blue and easy.
400 - gui: audio streaming is now handled by audiod. Time display shows
401 playback time rather than streaming time
402 - slider: update to libzmw-0.2.0
403 - para_krell: fix crash on server shutdown
404 - switch from gzip to bzip2
405
406
407 ----------------------------------------
408 0.1.7 (2005-04-18) "melting penetration"
409 ----------------------------------------
410
411 The main change in this release is clearly the oggvorbis rewrite,
412 but there are also lots of smaller changes. If you intend to use both
413 the mp3 and the ogg plugin, it is recommended to use software mixing,
414 e.g. the dmix plugin which is provided by ALSA.
415
416 - new executables: para_ovsend and para_ovrecv for sending/receiving
417 oggvorbis files via rtp. Requires the open rtp library. Get it at
418 http://www.linphone.org/ortp/
419 - rewrite of the ogg_vorbis core code
420 - configure detects libzmw and, if detected, includes
421 para_slider to the list of binaries to be built by make
422 - server stream writers read from their associated fifo rather
423 than from stdin
424 - slider: two new sliders, lastplayed and numplayed
425 - fix nasty double free bug which caused random segfaults in case of
426 mp3 files with invalid header information
427 - gui: new command line option: --stream_timeout=seconds to
428 deactivate a slot if it is idle for that many seconds (default=`5')
429 - diffstats
430
431
432 ---------------------------------------
433 0.1.6 (2005-03-05) "asymptotic balance"
434 ---------------------------------------
435
436 Only little user-visible changes in this release. Mainly bugfixes and
437 core code cleanup. This is probably the most stable version ever if you
438 stick to mp3...
439
440 - fix several memory leaks
441 - rename default name of mysql database from "music" to "paraslash".
442 Use para_server's --mysql_database option if you do not want to
443 rename your old database.
444 - rework ogg vorbis code
445 - make update command work on mysql servers with LOCAL_INFILE
446 disabled
447 - gui: improved stream I/O (slots)
448 - simplified audio format API
449 - para_pob_ogg is gone
450
451 ------------------------------------
452 0.1.5 (2004-12-31) "opaque eternity"
453 ------------------------------------
454
455 Let's slide gently into the new year.
456
457 - new: para_slider (not built automatically, type "make
458 para_slider" to build). A toy for those who always felt that
459 creating stream definitions is difficult. See screenshots,
460 README and FEATURES for more info.
461 - improved signal handling. Fixes server segfault on SIGHUP
462 for linux kernels newer than Aug 24 2004 and makes para_gui
463 race-free.
464 - reload database tool on SIGHUP
465 - improved help message for sl
466 - do not log "broken pipe" messages as errors. They are
467 perfectly ok.
468 - fix wrong error message on permission errors
469
470 -----------------------------------------
471 0.1.4 (2004-12-19) "tunneling transition"
472 -----------------------------------------
473
474 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
475 Hopefully, most of them got wiped out with this release. Some
476 enhancements went also in.
477
478 - improved error diagnostics for all commands
479 - stradd/picadd: overwrite previous contents if entry already
480 exists, rather than returning errors
481 - stradd: use current stream if invoked without args
482 - faster (and hopefully more stable) ogg-vorbis handling
483 - para_krell: reap children to avoid zombie-flooding in case
484 no server is running
485 - si: report also server pid
486 - server: don't busy-loop if dbtool reports only invalid files.
487 - gui: CTRL+C works again, fix stream_read command line option
488 - fix pic_add, hist
489 - fix mysql dbtool startup in case no database exists
490 - many small fixes and cleanups
491
492 ---------------------------------------
493 0.1.3: (2004-12-10) "vanishing inertia"
494 ---------------------------------------
495
496 Starting from this release, the database tools are integrated in the
497 server binary. This decreases server startup time, reduces code size
498 and speeds up database commands. However, the layout of the underlying
499 mysql database changed only slightly and 0.1.3 should be backwards
500 compatible in that respect.
501
502 Visible changes:
503
504 - If mysql is not detected at compile time, or fails to init
505 at runtime, fall back to the dopey database tool which should
506 always work.
507 - para_dbtool and dbtool.conf are gone. All mysql specific
508 options are read from server.conf and are prefixed by 'mysql_'.
509 - new command: cdt (change database tool)
510 - new command line option: dbtool (choose startup database tool)
511 - The name of current stream is now stored in the database,
512 so paraslash remembers its current stream when restarted.
513 - new command: csp (change stream and play)
514 - para_gui also reports current database tool and server uptime
515
516
517 -------------------------------------------
518 0.1.2: (2004-11-28) "spherical fluctuation"
519 -------------------------------------------
520
521 Point release before the big dbtool changes go in.
522
523 - dbtool: rename ca to cam (copy all meta data). It now also
524 copies numplayed and lastplayed time as well as the picture
525 id.
526 - fix endless-loop-bug caused by mp3 files with invalid header
527
528 -----------------------------------------
529 0.1.1: (2004-11-05) "floating atmosphere"
530 -----------------------------------------
531
532 - gkrellm plugin
533 - new dbtool command: mbox. Browse your sound-file collection
534 with your favorite mail reader.
535 - several small fixes
536
537 -------------------------------------
538 0.1.0: (2204-10-22) "rotating cortex"
539 -------------------------------------
540
541 - fix logging bug for loglevel > VERBOSE
542 - fix skip command
543 - correct timings for vbr mp3s
544 - modular audio format support
