5 0.?.? (to be announced) "sonic convolution"
6 -------------------------------------------
7
8 A bunch of new features and core changes.
9
10 - the new paraslash scheduler, short and sweet.
11 - Support for m4a files via the new aac filter/ and audio
12 format handler. (requires libfaad)
13 - new writer: osxplay (thanks to Gerd Becker)
14 - writers are integrated in para_audiod
15 - para_client is integrated in para_audiod
16 - each writer of para_write has its own command line parser,
17 just like para_recv and para_filter.
18 - random/playlist selector: improved info strings
19 - new audiod commands: tasks, kill
20 - para_client/para_audioc use the error subsystem
21
22
23 ------------------------------------------
24 0.2.12 (2006-05-12) "oriented abstraction"
25 ------------------------------------------
26
27 Many user-visible changes in this release and lots of new
28 features:
29
30
31 - the new optional dccp sender/receiver. It uses the datagram
32 congestion control protocol. You'll need a fairly new kernel
33 for this.
34 - paraslash works on Mac OS X (thanks to Gerd Becker)
35 - para_play renamed to para_write
36 - modular output plugin design (writers) for para_write
37 - new file_writer output plugin for para_write
38 - compress filter speed improvements
39 - update to libortp-0.9.1
40 - update to gengetopt-2.17rc
41 - para_client no longer depends on libreadline (as the
42 code for the interactive mode was removed).
43 - gcc-2-95 is no longer a supported compiler. It may still
44 work, but it gets no more testing.
45 - the tarball no longer contains the screenshot images which
46 reduces its size quite a bit.
47 - configure: new command line options: --enable-mysql-headers
48 and --enable-mysql-libs
49
50 ------------------------------------
51 0.2.11 (2006-03-11) "atomic duality"
52 ------------------------------------
53
54 Here it is, the first paraslash release developed with git. There
55 are fairly many user-visible changes in this release. As two out of
56 the three "database tools" of paraslash don't use a database at all,
57 they are now called "audio file selectors" instead.
58
59
60 - the cdt command (change database tool) becomes chs (change
61 selector)
62 - no more colon separators: The syntax of some options of
63 para_audiod and para_filter have changed. Use --help for
64 more info (and some examples).
65 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
66 - switch from cvs to git (should've done that earlier)
67 - the new ipc subsystem
68 - new audio file selector: playlist
69 - para_server: the dopey selector is now called "random",
70 and is the default selector. Use the --selector option to
71 choose another selector at startup, or the chs command to
72 change the selector at runtime.
73 - X86_64 fixes (thanks to Steffen Klassert)
74 - para_play fixes
75
76
77 --------------------------------------
78 0.2.10 (2006-02-17) "cyclic attractor"
79 --------------------------------------
80
81 Huge documentation update, a scrollable window for para_gui, ortp
82 improvements, and of course many small fixes not mentioned here.
83 The diffstat below is rather misleading as most insertions are due
84 to the new source documentation.
85
86 - autoconf cleanup
87 - para_server also uses the new error subsystem
88 - lots of new documentation (UTSL)
89 - gui improvements:
90 - keysyms for cursor keys and for next/previous page keys
91 - scrollable output window
92 - new internal commands: scroll up/down, page up/down
93 - fix color of command output.
94 - ortp: the --chunk_time and --header flags are no longer needed
95 for para_recv/para_audiod as this information is now encoded in
96 each rtp packet sent by para_server.
97
98
99 -------------------------------------------
100 0.2.9 (2006-01-24) "progressive turbulence"
101 -------------------------------------------
102
103 Internal audiod receivers/filters, the new error subsystem and
104 a lot of small improvements.
105
106 - para_recv and para_filter are integrated into the para_audiod
107 binary, i.e. audiod no longer spawns a new process for
108 each receiver/filter. As para_recv and para_filter might be
109 useful as standalone programs, they still get built (linked
110 against the same object files that are also used for audiod).
111 - further ortp timing improvements should reduce the CPU usage
112 of the ortp receiver.
113 - improved audio grabbing. The 'grab' command of para_audiod
114 has its own set of command line options. Read the output of
115 "para_audioc help grab" for more info.
116 - oggdec: configurable input prebuffer size.
117 - the new error subsystem gives better error diagnostics
118 and reduces code size.
119
120
121 -----------------------------------------
122 0.2.8 (2006-01-02) "dynamic accumulation"
123 -----------------------------------------
124
125 The new modular filter design and the para_play-hangs bugfix.
126
127 - new executable: para_filter. It combines para_mp3dec,
128 para_oggdec and para_compress. It also adds a further filter
129 type, wav, that just inserts a wave header at the desired point
130 of the filter chain. All 'piping' is done in-memory (i.e. no
131 read/write operations are used).
132 - para_play: fix a stupid bug that caused it to hang under
133 certain circumstances.
134
135
136 -------------------------------------------
137 0.2.7 (2006-12-27) "transparent invariance"
138 -------------------------------------------
139
140 Not many user-visible changes but a fair amount of internal improvements.
141
142
143 - The http sender buffers data if it can not be sent
144 out immediately (because the socket is not writable). This
145 should prevent para_server from shutting down the connection
146 too early on a loaded network.
147 - para_play also prebuffers data if it is told to start at a
148 future time by the --start_time option.
149 - The return of para_recv: It combines para_ortp_recv and
150 para_http_recv. Use the --receiver option to switch between
151 the two. para_recv builds without libortp, but contains
152 only the http receiver in this case.
153 - update to ortp 0.8.1. As this ortp release contains incompatible
154 changes, para_recv-0.2.7 won't link against older ortp libs.
155 - improved ortp timings.
156 - use of gcc-extensions that #define away for non-gcc and
157 gcc < 3.0.
158
159
160 -------------------------------------------
161 0.2.6 (2005-10-29) "recursive compensation"
162 -------------------------------------------
163
164 Transparent session encryption (uses openssl's Alleged RC4 cipher),
165 the internal find command and several other improvements and cleanups.
166
167 - Encrypt the session if encryption is requested by the client
168 (default for para_client 0.2.6). This is backwards
169 compatible, so older clients can still connect to para_server
170 0.2.6. Use the new client option --plain to request an
171 uncrypted session (off by default, must be set to on in
172 order to connect to para_server 0.2.x with 0 <= x <= 5).
173 - para_server uses an internal function to locate audio files
174 rather than calling find(1). The server option
175 --mysql_audio_file_dir replaces --mysql_find_cmd.
176 - documentation update
177 - man pages
178 - header file cleanup
179 - para_client code cleanup
180 - para_gui: faster display of output of display commands
181
182
183 ------------------------------------------
184 0.2.5 (2005-10-13) "aggressive_resolution"
185 ------------------------------------------
186
187 This release adds internal senders, i.e. no more external programs are
188 spawned for sending out the audio data. There are two different senders
189 available: The http sender and the ortp sender (former para_send which
190 is no longer needed).
191
192 The new sender code has a plugin-like design so it can be easily
193 extended should there be be any future need for supporting another
194 network streaming protocol. All senders are completely independent of
195 each other. In particular, the http and the ortp sender can operate
196 in parallel.
197
198 - new server command: sender to control senders at runtime.
199 Read the output of "para_server -h" and "para_client help
200 sender" for more information.
201 - para_recv renamed to para_ortp_recv
202 - new executable: para_http_recv, a simple command line
203 http receiver.
204 - major afs/mp3/ogg code simplifications due to internal
205 senders.
206 - ogg timing improvements
207 - fix several minor memory leaks (found by valgrind)
208 - empty stream definitions work again
209 - com_ne(): ignore errors on remove
210 - audiod: fix segfault on server restart
211
212
213 ---------------------------------------
214 0.2.4 (2005-09-21) "toxic anticipation"
215 ---------------------------------------
216
217 Several small improvements, fixes and the new grab command.
218
219 - audiod:
220 - new command: "grab" to grab the output of the stream reader
221 or any filters. Read the output of "para_audioc help grab"
222 for more information.
223 - fix memory leak
224 - code cleanup
225 - audioc: new command line option: --bufsize to specify a
226 buffer size different from the default size 8192.
227 - improved error diagnostics for para_play.
228 - new configure option: --enable-ssldir so search for openssl in
229 non-standard places
230 - sdl_gui: Make it look nice again for 1024x768
231 - server: report total size of memory allocated with sbrk by malloc,
232 new command line option: --announce_time
233
234
235 -----------------------------------------
236 0.2.3 (2005-09-01) "hydrophilic movement"
237 -----------------------------------------
238
239 Two new executables and major feature enhancements.
240
241 - audiod filters: It is now possible to specify arbitrary many
242 (including none) filters for each supported audio
243 format. This can be used e.g. for normalizing volume,
244 transforming or grabbing the audio stream, or for using
245 visualizers. Read the output of "para_audiod -h" for the
246 syntax of the new --filter_cmd option.
247 - new executable: para_play, a tiny alsa player. It
248 can play wave files or raw pcm (16 bit little endian)
249 from stdin.
250 - new executable: para_compress, a dynamic range compressor
251 intended to keep audio output at a consistent volume. Derived
252 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
253 - audiod: New option: --stream_delay. This can be used in
254 a local network to syncronize the audio output of all
255 clients that play the same stream.
256
257
258 ------------------------------------------
259 0.2.2 (2005-08-19) "tangential excitation"
260 ------------------------------------------
261
262 Mostly internal changes in this release, but also some new commands
263 for the mysql database tool.
264
265 - cleanup exec.c, fix para_exec bug
266 - compile time loglevel (log messages below the given level
267 won't be compiled in, which reduces the size of the
268 resulting binaries)
269 - new log macros that shorten the size of the source code.
270 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
271 to send only zeros. With this workaround, para_audioc works
272 again.
273 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
274 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
275 (new entry), "snp" (set numplayed). Read the manual for more
276 information.
277
278
279 ---------------------------------------
280 0.2.1 (2005-08-15) "surreal experience"
281 ---------------------------------------
282
283 Here comes paraslash-0.2.1. It contains a couple of new features and,
284 surprise, only minor bug fixes.
285
286 - kill noisy mp3 debug message
287 - cleanup of the build system
288 - para_server and para_client directly use the crypto routines
289 of the openssl library rather than invoking the openssl command
290 line utitlity
291 - server/audiod: new option --user to switch to the given user
292 when invoked as root. Read the output of "para_server -h" for
293 more information.
294 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
295 status. Default: "para_audioc stat"
296 - sdl_gui: new option --pic_cmd to be used to download the picture.
297 Default: "para_client pic"
298 - audiod: 5 slots ought to be enough for everybody
299 - audiod: new status item: Uptime, kill hup command
300
301
302
303 ------------------------------------------
304 0.2.0 (2005-08-06) "distributed diffusion"
305 ------------------------------------------
306
307 After several month of increased development activity, paraslash-0.2.0
308 has arrived. It contains many new features and is much more
309 self-contained than the old 0.1.x series. Enjoy!
310
311
312 - para_server: fix hang on song change and crash on sighup.
313 Speed up mysql queries. The DIR_LIKE macro is gone.
314 - new executables: para_audiod, the local audio daemon that
315 starts playback (uses SCM_CREDENTIALS socket magic) and
316 para_audioc, the corresponding client.
317 - new executables: para_mp3dec/para_oggdec, two really teensy
318 decoders. para_mp3dec is based on libmad, para_oggdec requires
319 libvorbisfile.
320 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
321 they are now called para_send and para_recv respectively.
322 - documentation updates
323 - para_gui is themable. For now there is the default theme that
324 looks as before and the simple theme: blue and easy.
325 - gui: audio streaming is now handled by audiod. Time display shows
326 playback time rather than streaming time
327 - slider: update to libzmw-0.2.0
328 - para_krell: fix crash on server shutdown
329 - switch from gzip to bzip2
330
331
332 ----------------------------------------
333 0.1.7 (2005-04-18) "melting penetration"
334 ----------------------------------------
335
336 The main change in this release is clearly the oggvorbis rewrite,
337 but there are also lots of smaller changes. If you intend to use both
338 the mp3 and the ogg plugin, it is recommended to use software mixing,
339 e.g. the dmix plugin which is provided by ALSA.
340
341 - new executables: para_ovsend and para_ovrecv for sending/receiving
342 oggvorbis files via rtp. Requires the open rtp library. Get it at
343 http://www.linphone.org/ortp/
344 - rewrite of the ogg_vorbis core code
345 - configure detects libzmw and, if detected, includes
346 para_slider to the list of binaries to be built by make
347 - server stream writers read from their associated fifo rather
348 than from stdin
349 - slider: two new sliders, lastplayed and numplayed
350 - fix nasty double free bug which caused random segfaults in case of
351 mp3 files with invalid header information
352 - gui: new command line option: --stream_timeout=seconds to
353 deactivate a slot if it is idle for that many seconds (default=`5')
354 - diffstats
355
356
357 ---------------------------------------
358 0.1.6 (2005-03-05) "asymptotic balance"
359 ---------------------------------------
360
361 Only little user-visible changes in this release. Mainly bugfixes and
362 core code cleanup. This is probably the most stable version ever if you
363 stick to mp3...
364
365 - fix several memory leaks
366 - rename default name of mysql database from "music" to "paraslash".
367 Use para_server's --mysql_database option if you do not want to
368 rename your old database.
369 - rework ogg vorbis code
370 - make update command work on mysql servers with LOCAL_INFILE
371 disabled
372 - gui: improved stream I/O (slots)
373 - simplified audio format API
374 - para_pob_ogg is gone
375
376 ------------------------------------
377 0.1.5 (2004-12-31) "opaque eternity"
378 ------------------------------------
379
380 Let's slide gently into the new year.
381
382 - new: para_slider (not built automatically, type "make
383 para_slider" to build). A toy for those who always felt that
384 creating stream definitions is difficult. See screenshots,
385 README and FEATURES for more info.
386 - improved signal handling. Fixes server segfault on SIGHUP
387 for linux kernels newer than Aug 24 2004 and makes para_gui
388 race-free.
389 - reload database tool on SIGHUP
390 - improved help message for sl
391 - do not log "broken pipe" messages as errors. They are
392 perfectly ok.
393 - fix wrong error message on permission errors
394
395 -----------------------------------------
396 0.1.4 (2004-12-19) "tunneling transition"
397 -----------------------------------------
398
399 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
400 Hopefully, most of them got wiped out with this release. Some
401 enhancements went also in.
402
403 - improved error diagnostics for all commands
404 - stradd/picadd: overwrite previous contents if entry already
405 exists, rather than returning errors
406 - stradd: use current stream if invoked without args
407 - faster (and hopefully more stable) ogg-vorbis handling
408 - para_krell: reap children to avoid zombie-flooding in case
409 no server is running
410 - si: report also server pid
411 - server: don't busy-loop if dbtool reports only invalid files.
412 - gui: CTRL+C works again, fix stream_read command line option
413 - fix pic_add, hist
414 - fix mysql dbtool startup in case no database exists
415 - many small fixes and cleanups
416
417 ---------------------------------------
418 0.1.3: (2004-12-10) "vanishing inertia"
419 ---------------------------------------
420
421 Starting from this release, the database tools are integrated in the
422 server binary. This decreases server startup time, reduces code size
423 and speeds up database commands. However, the layout of the underlying
424 mysql database changed only slightly and 0.1.3 should be backwards
425 compatible in that respect.
426
427 Visible changes:
428
429 - If mysql is not detected at compile time, or fails to init
430 at runtime, fall back to the dopey database tool which should
431 always work.
432 - para_dbtool and dbtool.conf are gone. All mysql specific
433 options are read from server.conf and are prefixed by 'mysql_'.
434 - new command: cdt (change database tool)
435 - new command line option: dbtool (choose startup database tool)
436 - The name of current stream is now stored in the database,
437 so paraslash remembers its current stream when restarted.
438 - new command: csp (change stream and play)
439 - para_gui also reports current database tool and server uptime
440
441
442 -------------------------------------------
443 0.1.2: (2004-11-28) "spherical fluctuation"
444 -------------------------------------------
445
446 Point release before the big dbtool changes go in.
447
448 - dbtool: rename ca to cam (copy all meta data). It now also
449 copies numplayed and lastplayed time as well as the picture
450 id.
451 - fix endless-loop-bug caused by mp3 files with invalid header
452
453 -----------------------------------------
454 0.1.1: (2004-11-05) "floating atmosphere"
455 -----------------------------------------
456
457 - gkrellm plugin
458 - new dbtool command: mbox. Browse your sound-file collection
459 with your favorite mail reader.
460 - several small fixes
461
462 -------------------------------------
463 0.1.0: (2204-10-22) "rotating cortex"
464 -------------------------------------
465
466 - fix logging bug for loglevel > VERBOSE
467 - fix skip command
468 - correct timings for vbr mp3s
469 - modular audio format support
470 - ogg-vorbis support (experimental)
471 - new server option: autoplay
472
473 -----------------------------------------
474 0.0.99: (2004-07-25) "harmonic deviation"
475 -----------------------------------------
476
477 - rename projectname from icc to paraslash (play, archive, rate
478 and stream large audio sets happily)
479 - paraslash is no longer restricted to one particular audio
480 streaming software
481 - new dbtool commands (stradd, strq, strdel) for easy stream
482 managment w/o configuration file. That obsoletes stream_defs
483 file/config option for dbtool.
484 - picadd accepts jpeg data from stdin
485 - new server commands: ps (select previous stream), sc (song change)
486 - new default pictures for sdl_gui
487 - gui: new key_map option for binding commands and internal
488 functions to arbitrary keys, nice help screen, rip out
489 soundcard/linux specific stuff, avoid noise artefacts while jumping,
490 show silly logo on startup
491 - new executables: para_fade for fading volume, para_dbadm for
492 manipulating attributes
493 - cdb adds _all_ tables to mysql database
494 - revised and beautified documentation
495 - sample dbtool rewritten in C
496 - autoconf
497
498 ---------------------------------------------
499 0.0.98: (2003-12-26) "incremental smoothness"
500 ---------------------------------------------
501
502 - kick icecast in favour of poc. That removes some races and reduces
503 core code considerably.
504 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
505 give finer info on afs' status.
506 - gui can start decoder (see config options). Further new gui
507 commands: refresh (^L), jmp (F1-F10)
508 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
509 terminates gui. This fixes dead instances consuming memory
510 continuously.
511 - new dbtool command: verb for sending verbatim sql queries.
512 - fix pid_list races (by removing pid_list)
513 - codename funnies
514
515 --------------------
516 0.0.97: (2003-10-26)
517 --------------------
518
519 - installation prefix now defaults to /usr/local
520 - new commands for gui: snozze, sleep and reread config
521 - config file for gui and sdl_gui
522 - fix problems with filenames containing funny characters
523 (reported by Thomas Forell)
524 - improved signal handling for gui, now it rereads conf on SIGHUP
525 - new dbtool command: cdb (create database)
526 - switch from argtable to gengetopt
527 - major code cleanup and speed improvements
528 - fix several potential buffer overflows
529 - many small fixes and cleanups
530
531 -------------------
532 0.0.96 (2003-08-30)
533 -------------------
534
535 - easy stream_defs syntax
536 - sdl_gui can display images associated to the file being played
537 - Major feature enhancements for icc_gui including dynamic text
538 placement and the top/bottom window design
539 - vrfy/clean now also checks for NULL values in attributes as
540 well as for invalid picture pointers
541 - fix long outstanding case sensitivity bug
542 - many small fixes and cleanups
543
544 -------------------
545 0.0.95 (2003-06-29)
546 -------------------
547
548 - sdl gui runs much faster
549 - new dbtool command: ca (copy attributes)
550 - count and display number of times the song has been played
