5 0.?.? (to be announced) "transient singularity"
6 ------------------------------------------------
7
8 ---------------------------------------
9 0.2.13 (2006-07-14) "sonic convolution"
10 ---------------------------------------
11
12 A bunch of new features and core changes.
13
14 - the new paraslash scheduler, short and sweet.
15 - Support for m4a/mp4 files via the new aac audio format
16 handler/filter (requires libfaad).
17 - each writer has its own command line parser, just like
18 para_recv and para_filter.
19 - para_client and para_audioc use the error subsystem
20 - writers are integrated in para_audiod (currently linux-only)
21 - para_client is integrated in para_audiod
22 - random/playlist selector: improved info strings
23 - new audiod commands: tasks, kill
24 - update to libortp-0.10.1
25 - para_fade: wake time defaults to 8 hours from now
26 - update to autoconf-2.60
27
28
29 ------------------------------------------
30 0.2.12 (2006-05-12) "oriented abstraction"
31 ------------------------------------------
32
33 Many user-visible changes in this release and lots of new
34 features:
35
36
37 - the new optional dccp sender/receiver. It uses the datagram
38 congestion control protocol. You'll need a fairly new kernel
39 for this.
40 - paraslash works on Mac OS X (thanks to Gerd Becker)
41 - para_play renamed to para_write
42 - modular output plugin design (writers) for para_write
43 - new file_writer output plugin for para_write
44 - compress filter speed improvements
45 - update to libortp-0.9.1
46 - update to gengetopt-2.17rc
47 - para_client no longer depends on libreadline (as the
48 code for the interactive mode was removed).
49 - gcc-2-95 is no longer a supported compiler. It may still
50 work, but it gets no more testing.
51 - the tarball no longer contains the screenshot images which
52 reduces its size quite a bit.
53 - configure: new command line options: --enable-mysql-headers
54 and --enable-mysql-libs
55
56 ------------------------------------
57 0.2.11 (2006-03-11) "atomic duality"
58 ------------------------------------
59
60 Here it is, the first paraslash release developed with git. There
61 are fairly many user-visible changes in this release. As two out of
62 the three "database tools" of paraslash don't use a database at all,
63 they are now called "audio file selectors" instead.
64
65
66 - the cdt command (change database tool) becomes chs (change
67 selector)
68 - no more colon separators: The syntax of some options of
69 para_audiod and para_filter have changed. Use --help for
70 more info (and some examples).
71 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
72 - switch from cvs to git (should've done that earlier)
73 - the new ipc subsystem
74 - new audio file selector: playlist
75 - para_server: the dopey selector is now called "random",
76 and is the default selector. Use the --selector option to
77 choose another selector at startup, or the chs command to
78 change the selector at runtime.
79 - X86_64 fixes (thanks to Steffen Klassert)
80 - para_play fixes
81
82
83 --------------------------------------
84 0.2.10 (2006-02-17) "cyclic attractor"
85 --------------------------------------
86
87 Huge documentation update, a scrollable window for para_gui, ortp
88 improvements, and of course many small fixes not mentioned here.
89 The diffstat below is rather misleading as most insertions are due
90 to the new source documentation.
91
92 - autoconf cleanup
93 - para_server also uses the new error subsystem
94 - lots of new documentation (UTSL)
95 - gui improvements:
96 - keysyms for cursor keys and for next/previous page keys
97 - scrollable output window
98 - new internal commands: scroll up/down, page up/down
99 - fix color of command output.
100 - ortp: the --chunk_time and --header flags are no longer needed
101 for para_recv/para_audiod as this information is now encoded in
102 each rtp packet sent by para_server.
103
104
105 -------------------------------------------
106 0.2.9 (2006-01-24) "progressive turbulence"
107 -------------------------------------------
108
109 Internal audiod receivers/filters, the new error subsystem and
110 a lot of small improvements.
111
112 - para_recv and para_filter are integrated into the para_audiod
113 binary, i.e. audiod no longer spawns a new process for
114 each receiver/filter. As para_recv and para_filter might be
115 useful as standalone programs, they still get built (linked
116 against the same object files that are also used for audiod).
117 - further ortp timing improvements should reduce the CPU usage
118 of the ortp receiver.
119 - improved audio grabbing. The 'grab' command of para_audiod
120 has its own set of command line options. Read the output of
121 "para_audioc help grab" for more info.
122 - oggdec: configurable input prebuffer size.
123 - the new error subsystem gives better error diagnostics
124 and reduces code size.
125
126
127 -----------------------------------------
128 0.2.8 (2006-01-02) "dynamic accumulation"
129 -----------------------------------------
130
131 The new modular filter design and the para_play-hangs bugfix.
132
133 - new executable: para_filter. It combines para_mp3dec,
134 para_oggdec and para_compress. It also adds a further filter
135 type, wav, that just inserts a wave header at the desired point
136 of the filter chain. All 'piping' is done in-memory (i.e. no
137 read/write operations are used).
138 - para_play: fix a stupid bug that caused it to hang under
139 certain circumstances.
140
141
142 -------------------------------------------
143 0.2.7 (2006-12-27) "transparent invariance"
144 -------------------------------------------
145
146 Not many user-visible changes but a fair amount of internal improvements.
147
148
149 - The http sender buffers data if it can not be sent
150 out immediately (because the socket is not writable). This
151 should prevent para_server from shutting down the connection
152 too early on a loaded network.
153 - para_play also prebuffers data if it is told to start at a
154 future time by the --start_time option.
155 - The return of para_recv: It combines para_ortp_recv and
156 para_http_recv. Use the --receiver option to switch between
157 the two. para_recv builds without libortp, but contains
158 only the http receiver in this case.
159 - update to ortp 0.8.1. As this ortp release contains incompatible
160 changes, para_recv-0.2.7 won't link against older ortp libs.
161 - improved ortp timings.
162 - use of gcc-extensions that #define away for non-gcc and
163 gcc < 3.0.
164
165
166 -------------------------------------------
167 0.2.6 (2005-10-29) "recursive compensation"
168 -------------------------------------------
169
170 Transparent session encryption (uses openssl's Alleged RC4 cipher),
171 the internal find command and several other improvements and cleanups.
172
173 - Encrypt the session if encryption is requested by the client
174 (default for para_client 0.2.6). This is backwards
175 compatible, so older clients can still connect to para_server
176 0.2.6. Use the new client option --plain to request an
177 uncrypted session (off by default, must be set to on in
178 order to connect to para_server 0.2.x with 0 <= x <= 5).
179 - para_server uses an internal function to locate audio files
180 rather than calling find(1). The server option
181 --mysql_audio_file_dir replaces --mysql_find_cmd.
182 - documentation update
183 - man pages
184 - header file cleanup
185 - para_client code cleanup
186 - para_gui: faster display of output of display commands
187
188
189 ------------------------------------------
190 0.2.5 (2005-10-13) "aggressive_resolution"
191 ------------------------------------------
192
193 This release adds internal senders, i.e. no more external programs are
194 spawned for sending out the audio data. There are two different senders
195 available: The http sender and the ortp sender (former para_send which
196 is no longer needed).
197
198 The new sender code has a plugin-like design so it can be easily
199 extended should there be be any future need for supporting another
200 network streaming protocol. All senders are completely independent of
201 each other. In particular, the http and the ortp sender can operate
202 in parallel.
203
204 - new server command: sender to control senders at runtime.
205 Read the output of "para_server -h" and "para_client help
206 sender" for more information.
207 - para_recv renamed to para_ortp_recv
208 - new executable: para_http_recv, a simple command line
209 http receiver.
210 - major afs/mp3/ogg code simplifications due to internal
211 senders.
212 - ogg timing improvements
213 - fix several minor memory leaks (found by valgrind)
214 - empty stream definitions work again
215 - com_ne(): ignore errors on remove
216 - audiod: fix segfault on server restart
217
218
219 ---------------------------------------
220 0.2.4 (2005-09-21) "toxic anticipation"
221 ---------------------------------------
222
223 Several small improvements, fixes and the new grab command.
224
225 - audiod:
226 - new command: "grab" to grab the output of the stream reader
227 or any filters. Read the output of "para_audioc help grab"
228 for more information.
229 - fix memory leak
230 - code cleanup
231 - audioc: new command line option: --bufsize to specify a
232 buffer size different from the default size 8192.
233 - improved error diagnostics for para_play.
234 - new configure option: --enable-ssldir so search for openssl in
235 non-standard places
236 - sdl_gui: Make it look nice again for 1024x768
237 - server: report total size of memory allocated with sbrk by malloc,
238 new command line option: --announce_time
239
240
241 -----------------------------------------
242 0.2.3 (2005-09-01) "hydrophilic movement"
243 -----------------------------------------
244
245 Two new executables and major feature enhancements.
246
247 - audiod filters: It is now possible to specify arbitrary many
248 (including none) filters for each supported audio
249 format. This can be used e.g. for normalizing volume,
250 transforming or grabbing the audio stream, or for using
251 visualizers. Read the output of "para_audiod -h" for the
252 syntax of the new --filter_cmd option.
253 - new executable: para_play, a tiny alsa player. It
254 can play wave files or raw pcm (16 bit little endian)
255 from stdin.
256 - new executable: para_compress, a dynamic range compressor
257 intended to keep audio output at a consistent volume. Derived
258 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
259 - audiod: New option: --stream_delay. This can be used in
260 a local network to syncronize the audio output of all
261 clients that play the same stream.
262
263
264 ------------------------------------------
265 0.2.2 (2005-08-19) "tangential excitation"
266 ------------------------------------------
267
268 Mostly internal changes in this release, but also some new commands
269 for the mysql database tool.
270
271 - cleanup exec.c, fix para_exec bug
272 - compile time loglevel (log messages below the given level
273 won't be compiled in, which reduces the size of the
274 resulting binaries)
275 - new log macros that shorten the size of the source code.
276 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
277 to send only zeros. With this workaround, para_audioc works
278 again.
279 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
280 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
281 (new entry), "snp" (set numplayed). Read the manual for more
282 information.
283
284
285 ---------------------------------------
286 0.2.1 (2005-08-15) "surreal experience"
287 ---------------------------------------
288
289 Here comes paraslash-0.2.1. It contains a couple of new features and,
290 surprise, only minor bug fixes.
291
292 - kill noisy mp3 debug message
293 - cleanup of the build system
294 - para_server and para_client directly use the crypto routines
295 of the openssl library rather than invoking the openssl command
296 line utitlity
297 - server/audiod: new option --user to switch to the given user
298 when invoked as root. Read the output of "para_server -h" for
299 more information.
300 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
301 status. Default: "para_audioc stat"
302 - sdl_gui: new option --pic_cmd to be used to download the picture.
303 Default: "para_client pic"
304 - audiod: 5 slots ought to be enough for everybody
305 - audiod: new status item: Uptime, kill hup command
306
307
308
309 ------------------------------------------
310 0.2.0 (2005-08-06) "distributed diffusion"
311 ------------------------------------------
312
313 After several month of increased development activity, paraslash-0.2.0
314 has arrived. It contains many new features and is much more
315 self-contained than the old 0.1.x series. Enjoy!
316
317
318 - para_server: fix hang on song change and crash on sighup.
319 Speed up mysql queries. The DIR_LIKE macro is gone.
320 - new executables: para_audiod, the local audio daemon that
321 starts playback (uses SCM_CREDENTIALS socket magic) and
322 para_audioc, the corresponding client.
323 - new executables: para_mp3dec/para_oggdec, two really teensy
324 decoders. para_mp3dec is based on libmad, para_oggdec requires
325 libvorbisfile.
326 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
327 they are now called para_send and para_recv respectively.
328 - documentation updates
329 - para_gui is themable. For now there is the default theme that
330 looks as before and the simple theme: blue and easy.
331 - gui: audio streaming is now handled by audiod. Time display shows
332 playback time rather than streaming time
333 - slider: update to libzmw-0.2.0
334 - para_krell: fix crash on server shutdown
335 - switch from gzip to bzip2
336
337
338 ----------------------------------------
339 0.1.7 (2005-04-18) "melting penetration"
340 ----------------------------------------
341
342 The main change in this release is clearly the oggvorbis rewrite,
343 but there are also lots of smaller changes. If you intend to use both
344 the mp3 and the ogg plugin, it is recommended to use software mixing,
345 e.g. the dmix plugin which is provided by ALSA.
346
347 - new executables: para_ovsend and para_ovrecv for sending/receiving
348 oggvorbis files via rtp. Requires the open rtp library. Get it at
349 http://www.linphone.org/ortp/
350 - rewrite of the ogg_vorbis core code
351 - configure detects libzmw and, if detected, includes
352 para_slider to the list of binaries to be built by make
353 - server stream writers read from their associated fifo rather
354 than from stdin
355 - slider: two new sliders, lastplayed and numplayed
356 - fix nasty double free bug which caused random segfaults in case of
357 mp3 files with invalid header information
358 - gui: new command line option: --stream_timeout=seconds to
359 deactivate a slot if it is idle for that many seconds (default=`5')
360 - diffstats
361
362
363 ---------------------------------------
364 0.1.6 (2005-03-05) "asymptotic balance"
365 ---------------------------------------
366
367 Only little user-visible changes in this release. Mainly bugfixes and
368 core code cleanup. This is probably the most stable version ever if you
369 stick to mp3...
370
371 - fix several memory leaks
372 - rename default name of mysql database from "music" to "paraslash".
373 Use para_server's --mysql_database option if you do not want to
374 rename your old database.
375 - rework ogg vorbis code
376 - make update command work on mysql servers with LOCAL_INFILE
377 disabled
378 - gui: improved stream I/O (slots)
379 - simplified audio format API
380 - para_pob_ogg is gone
381
382 ------------------------------------
383 0.1.5 (2004-12-31) "opaque eternity"
384 ------------------------------------
385
386 Let's slide gently into the new year.
387
388 - new: para_slider (not built automatically, type "make
389 para_slider" to build). A toy for those who always felt that
390 creating stream definitions is difficult. See screenshots,
391 README and FEATURES for more info.
392 - improved signal handling. Fixes server segfault on SIGHUP
393 for linux kernels newer than Aug 24 2004 and makes para_gui
394 race-free.
395 - reload database tool on SIGHUP
396 - improved help message for sl
397 - do not log "broken pipe" messages as errors. They are
398 perfectly ok.
399 - fix wrong error message on permission errors
400
401 -----------------------------------------
402 0.1.4 (2004-12-19) "tunneling transition"
403 -----------------------------------------
404
405 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
406 Hopefully, most of them got wiped out with this release. Some
407 enhancements went also in.
408
409 - improved error diagnostics for all commands
410 - stradd/picadd: overwrite previous contents if entry already
411 exists, rather than returning errors
412 - stradd: use current stream if invoked without args
413 - faster (and hopefully more stable) ogg-vorbis handling
414 - para_krell: reap children to avoid zombie-flooding in case
415 no server is running
416 - si: report also server pid
417 - server: don't busy-loop if dbtool reports only invalid files.
418 - gui: CTRL+C works again, fix stream_read command line option
419 - fix pic_add, hist
420 - fix mysql dbtool startup in case no database exists
421 - many small fixes and cleanups
422
423 ---------------------------------------
424 0.1.3: (2004-12-10) "vanishing inertia"
425 ---------------------------------------
426
427 Starting from this release, the database tools are integrated in the
428 server binary. This decreases server startup time, reduces code size
429 and speeds up database commands. However, the layout of the underlying
430 mysql database changed only slightly and 0.1.3 should be backwards
431 compatible in that respect.
432
433 Visible changes:
434
435 - If mysql is not detected at compile time, or fails to init
436 at runtime, fall back to the dopey database tool which should
437 always work.
438 - para_dbtool and dbtool.conf are gone. All mysql specific
439 options are read from server.conf and are prefixed by 'mysql_'.
440 - new command: cdt (change database tool)
441 - new command line option: dbtool (choose startup database tool)
442 - The name of current stream is now stored in the database,
443 so paraslash remembers its current stream when restarted.
444 - new command: csp (change stream and play)
445 - para_gui also reports current database tool and server uptime
446
447
448 -------------------------------------------
449 0.1.2: (2004-11-28) "spherical fluctuation"
450 -------------------------------------------
451
452 Point release before the big dbtool changes go in.
453
454 - dbtool: rename ca to cam (copy all meta data). It now also
455 copies numplayed and lastplayed time as well as the picture
456 id.
457 - fix endless-loop-bug caused by mp3 files with invalid header
458
459 -----------------------------------------
460 0.1.1: (2004-11-05) "floating atmosphere"
461 -----------------------------------------
462
463 - gkrellm plugin
464 - new dbtool command: mbox. Browse your sound-file collection
465 with your favorite mail reader.
466 - several small fixes
467
468 -------------------------------------
469 0.1.0: (2204-10-22) "rotating cortex"
470 -------------------------------------
471
472 - fix logging bug for loglevel > VERBOSE
473 - fix skip command
474 - correct timings for vbr mp3s
475 - modular audio format support
476 - ogg-vorbis support (experimental)
477 - new server option: autoplay
478
479 -----------------------------------------
480 0.0.99: (2004-07-25) "harmonic deviation"
481 -----------------------------------------
482
483 - rename projectname from icc to paraslash (play, archive, rate
484 and stream large audio sets happily)
485 - paraslash is no longer restricted to one particular audio
486 streaming software
487 - new dbtool commands (stradd, strq, strdel) for easy stream
488 managment w/o configuration file. That obsoletes stream_defs
489 file/config option for dbtool.
490 - picadd accepts jpeg data from stdin
491 - new server commands: ps (select previous stream), sc (song change)
492 - new default pictures for sdl_gui
493 - gui: new key_map option for binding commands and internal
494 functions to arbitrary keys, nice help screen, rip out
495 soundcard/linux specific stuff, avoid noise artefacts while jumping,
496 show silly logo on startup
497 - new executables: para_fade for fading volume, para_dbadm for
498 manipulating attributes
499 - cdb adds _all_ tables to mysql database
500 - revised and beautified documentation
501 - sample dbtool rewritten in C
502 - autoconf
503
504 ---------------------------------------------
505 0.0.98: (2003-12-26) "incremental smoothness"
506 ---------------------------------------------
507
508 - kick icecast in favour of poc. That removes some races and reduces
509 core code considerably.
510 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
511 give finer info on afs' status.
512 - gui can start decoder (see config options). Further new gui
513 commands: refresh (^L), jmp (F1-F10)
514 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
515 terminates gui. This fixes dead instances consuming memory
516 continuously.
517 - new dbtool command: verb for sending verbatim sql queries.
518 - fix pid_list races (by removing pid_list)
519 - codename funnies
520
521 --------------------
522 0.0.97: (2003-10-26)
523 --------------------
524
525 - installation prefix now defaults to /usr/local
526 - new commands for gui: snozze, sleep and reread config
527 - config file for gui and sdl_gui
528 - fix problems with filenames containing funny characters
529 (reported by Thomas Forell)
530 - improved signal handling for gui, now it rereads conf on SIGHUP
531 - new dbtool command: cdb (create database)
532 - switch from argtable to gengetopt
533 - major code cleanup and speed improvements
534 - fix several potential buffer overflows
535 - many small fixes and cleanups
536
537 -------------------
538 0.0.96 (2003-08-30)
539 -------------------
540
541 - easy stream_defs syntax
542 - sdl_gui can display images associated to the file being played
543 - Major feature enhancements for icc_gui including dynamic text
544 placement and the top/bottom window design
545 - vrfy/clean now also checks for NULL values in attributes as
546 well as for invalid picture pointers
547 - fix long outstanding case sensitivity bug
548 - many small fixes and cleanups
549
550 -------------------
551 0.0.95 (2003-06-29)
