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