4 ------------------------------------------------
5 0.2.14 (to be announced) "transient singularity"
6 ------------------------------------------------
7
8 - new output plugin for Mac Os: the osx writer
9 - rename configure command line options from --enable-xxx-headers to
10 --with-xxx-headers and --enable-xxx-libs by --with-xxx-libs
11 - configure: new command line options: --with-mad-headers
12 and --with-mad-libs
13 - some small robustness fixes
14
15 ---------------------------------------
16 0.2.13 (2006-07-14) "sonic convolution"
17 ---------------------------------------
18
19 A bunch of new features and core changes.
20
21 - the new paraslash scheduler, short and sweet.
22 - Support for m4a/mp4 files via the new aac audio format
23 handler/filter (requires libfaad).
24 - each writer has its own command line parser, just like
25 para_recv and para_filter.
26 - para_client and para_audioc use the error subsystem
27 - writers are integrated in para_audiod (currently linux-only)
28 - para_client is integrated in para_audiod
29 - random/playlist selector: improved info strings
30 - new audiod commands: tasks, kill
31 - update to libortp-0.10.1
32 - para_fade: wake time defaults to 8 hours from now
33 - update to autoconf-2.60
34
35
36 ------------------------------------------
37 0.2.12 (2006-05-12) "oriented abstraction"
38 ------------------------------------------
39
40 Many user-visible changes in this release and lots of new
41 features:
42
43
44 - the new optional dccp sender/receiver. It uses the datagram
45 congestion control protocol. You'll need a fairly new kernel
46 for this.
47 - paraslash works on Mac OS X (thanks to Gerd Becker)
48 - para_play renamed to para_write
49 - modular output plugin design (writers) for para_write
50 - new file_writer output plugin for para_write
51 - compress filter speed improvements
52 - update to libortp-0.9.1
53 - update to gengetopt-2.17rc
54 - para_client no longer depends on libreadline (as the
55 code for the interactive mode was removed).
56 - gcc-2-95 is no longer a supported compiler. It may still
57 work, but it gets no more testing.
58 - the tarball no longer contains the screenshot images which
59 reduces its size quite a bit.
60 - configure: new command line options: --enable-mysql-headers
61 and --enable-mysql-libs
62
63 ------------------------------------
64 0.2.11 (2006-03-11) "atomic duality"
65 ------------------------------------
66
67 Here it is, the first paraslash release developed with git. There
68 are fairly many user-visible changes in this release. As two out of
69 the three "database tools" of paraslash don't use a database at all,
70 they are now called "audio file selectors" instead.
71
72
73 - the cdt command (change database tool) becomes chs (change
74 selector)
75 - no more colon separators: The syntax of some options of
76 para_audiod and para_filter have changed. Use --help for
77 more info (and some examples).
78 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
79 - switch from cvs to git (should've done that earlier)
80 - the new ipc subsystem
81 - new audio file selector: playlist
82 - para_server: the dopey selector is now called "random",
83 and is the default selector. Use the --selector option to
84 choose another selector at startup, or the chs command to
85 change the selector at runtime.
86 - X86_64 fixes (thanks to Steffen Klassert)
87 - para_play fixes
88
89
90 --------------------------------------
91 0.2.10 (2006-02-17) "cyclic attractor"
92 --------------------------------------
93
94 Huge documentation update, a scrollable window for para_gui, ortp
95 improvements, and of course many small fixes not mentioned here.
96 The diffstat below is rather misleading as most insertions are due
97 to the new source documentation.
98
99 - autoconf cleanup
100 - para_server also uses the new error subsystem
101 - lots of new documentation (UTSL)
102 - gui improvements:
103 - keysyms for cursor keys and for next/previous page keys
104 - scrollable output window
105 - new internal commands: scroll up/down, page up/down
106 - fix color of command output.
107 - ortp: the --chunk_time and --header flags are no longer needed
108 for para_recv/para_audiod as this information is now encoded in
109 each rtp packet sent by para_server.
110
111
112 -------------------------------------------
113 0.2.9 (2006-01-24) "progressive turbulence"
114 -------------------------------------------
115
116 Internal audiod receivers/filters, the new error subsystem and
117 a lot of small improvements.
118
119 - para_recv and para_filter are integrated into the para_audiod
120 binary, i.e. audiod no longer spawns a new process for
121 each receiver/filter. As para_recv and para_filter might be
122 useful as standalone programs, they still get built (linked
123 against the same object files that are also used for audiod).
124 - further ortp timing improvements should reduce the CPU usage
125 of the ortp receiver.
126 - improved audio grabbing. The 'grab' command of para_audiod
127 has its own set of command line options. Read the output of
128 "para_audioc help grab" for more info.
129 - oggdec: configurable input prebuffer size.
130 - the new error subsystem gives better error diagnostics
131 and reduces code size.
132
133
134 -----------------------------------------
135 0.2.8 (2006-01-02) "dynamic accumulation"
136 -----------------------------------------
137
138 The new modular filter design and the para_play-hangs bugfix.
139
140 - new executable: para_filter. It combines para_mp3dec,
141 para_oggdec and para_compress. It also adds a further filter
142 type, wav, that just inserts a wave header at the desired point
143 of the filter chain. All 'piping' is done in-memory (i.e. no
144 read/write operations are used).
145 - para_play: fix a stupid bug that caused it to hang under
146 certain circumstances.
147
148
149 -------------------------------------------
150 0.2.7 (2006-12-27) "transparent invariance"
151 -------------------------------------------
152
153 Not many user-visible changes but a fair amount of internal improvements.
154
155
156 - The http sender buffers data if it can not be sent
157 out immediately (because the socket is not writable). This
158 should prevent para_server from shutting down the connection
159 too early on a loaded network.
160 - para_play also prebuffers data if it is told to start at a
161 future time by the --start_time option.
162 - The return of para_recv: It combines para_ortp_recv and
163 para_http_recv. Use the --receiver option to switch between
164 the two. para_recv builds without libortp, but contains
165 only the http receiver in this case.
166 - update to ortp 0.8.1. As this ortp release contains incompatible
167 changes, para_recv-0.2.7 won't link against older ortp libs.
168 - improved ortp timings.
169 - use of gcc-extensions that #define away for non-gcc and
170 gcc < 3.0.
171
172
173 -------------------------------------------
174 0.2.6 (2005-10-29) "recursive compensation"
175 -------------------------------------------
176
177 Transparent session encryption (uses openssl's Alleged RC4 cipher),
178 the internal find command and several other improvements and cleanups.
179
180 - Encrypt the session if encryption is requested by the client
181 (default for para_client 0.2.6). This is backwards
182 compatible, so older clients can still connect to para_server
183 0.2.6. Use the new client option --plain to request an
184 uncrypted session (off by default, must be set to on in
185 order to connect to para_server 0.2.x with 0 <= x <= 5).
186 - para_server uses an internal function to locate audio files
187 rather than calling find(1). The server option
188 --mysql_audio_file_dir replaces --mysql_find_cmd.
189 - documentation update
190 - man pages
191 - header file cleanup
192 - para_client code cleanup
193 - para_gui: faster display of output of display commands
194
195
196 ------------------------------------------
197 0.2.5 (2005-10-13) "aggressive_resolution"
198 ------------------------------------------
199
200 This release adds internal senders, i.e. no more external programs are
201 spawned for sending out the audio data. There are two different senders
202 available: The http sender and the ortp sender (former para_send which
203 is no longer needed).
204
205 The new sender code has a plugin-like design so it can be easily
206 extended should there be be any future need for supporting another
207 network streaming protocol. All senders are completely independent of
208 each other. In particular, the http and the ortp sender can operate
209 in parallel.
210
211 - new server command: sender to control senders at runtime.
212 Read the output of "para_server -h" and "para_client help
213 sender" for more information.
214 - para_recv renamed to para_ortp_recv
215 - new executable: para_http_recv, a simple command line
216 http receiver.
217 - major afs/mp3/ogg code simplifications due to internal
218 senders.
219 - ogg timing improvements
220 - fix several minor memory leaks (found by valgrind)
221 - empty stream definitions work again
222 - com_ne(): ignore errors on remove
223 - audiod: fix segfault on server restart
224
225
226 ---------------------------------------
227 0.2.4 (2005-09-21) "toxic anticipation"
228 ---------------------------------------
229
230 Several small improvements, fixes and the new grab command.
231
232 - audiod:
233 - new command: "grab" to grab the output of the stream reader
234 or any filters. Read the output of "para_audioc help grab"
235 for more information.
236 - fix memory leak
237 - code cleanup
238 - audioc: new command line option: --bufsize to specify a
239 buffer size different from the default size 8192.
240 - improved error diagnostics for para_play.
241 - new configure option: --enable-ssldir so search for openssl in
242 non-standard places
243 - sdl_gui: Make it look nice again for 1024x768
244 - server: report total size of memory allocated with sbrk by malloc,
245 new command line option: --announce_time
246
247
248 -----------------------------------------
249 0.2.3 (2005-09-01) "hydrophilic movement"
250 -----------------------------------------
251
252 Two new executables and major feature enhancements.
253
254 - audiod filters: It is now possible to specify arbitrary many
255 (including none) filters for each supported audio
256 format. This can be used e.g. for normalizing volume,
257 transforming or grabbing the audio stream, or for using
258 visualizers. Read the output of "para_audiod -h" for the
259 syntax of the new --filter_cmd option.
260 - new executable: para_play, a tiny alsa player. It
261 can play wave files or raw pcm (16 bit little endian)
262 from stdin.
263 - new executable: para_compress, a dynamic range compressor
264 intended to keep audio output at a consistent volume. Derived
265 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
266 - audiod: New option: --stream_delay. This can be used in
267 a local network to syncronize the audio output of all
268 clients that play the same stream.
269
270
271 ------------------------------------------
272 0.2.2 (2005-08-19) "tangential excitation"
273 ------------------------------------------
274
275 Mostly internal changes in this release, but also some new commands
276 for the mysql database tool.
277
278 - cleanup exec.c, fix para_exec bug
279 - compile time loglevel (log messages below the given level
280 won't be compiled in, which reduces the size of the
281 resulting binaries)
282 - new log macros that shorten the size of the source code.
283 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
284 to send only zeros. With this workaround, para_audioc works
285 again.
286 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
287 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
288 (new entry), "snp" (set numplayed). Read the manual for more
289 information.
290
291
292 ---------------------------------------
293 0.2.1 (2005-08-15) "surreal experience"
294 ---------------------------------------
295
296 Here comes paraslash-0.2.1. It contains a couple of new features and,
297 surprise, only minor bug fixes.
298
299 - kill noisy mp3 debug message
300 - cleanup of the build system
301 - para_server and para_client directly use the crypto routines
302 of the openssl library rather than invoking the openssl command
303 line utitlity
304 - server/audiod: new option --user to switch to the given user
305 when invoked as root. Read the output of "para_server -h" for
306 more information.
307 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
308 status. Default: "para_audioc stat"
309 - sdl_gui: new option --pic_cmd to be used to download the picture.
310 Default: "para_client pic"
311 - audiod: 5 slots ought to be enough for everybody
312 - audiod: new status item: Uptime, kill hup command
313
314
315
316 ------------------------------------------
317 0.2.0 (2005-08-06) "distributed diffusion"
318 ------------------------------------------
319
320 After several month of increased development activity, paraslash-0.2.0
321 has arrived. It contains many new features and is much more
322 self-contained than the old 0.1.x series. Enjoy!
323
324
325 - para_server: fix hang on song change and crash on sighup.
326 Speed up mysql queries. The DIR_LIKE macro is gone.
327 - new executables: para_audiod, the local audio daemon that
328 starts playback (uses SCM_CREDENTIALS socket magic) and
329 para_audioc, the corresponding client.
330 - new executables: para_mp3dec/para_oggdec, two really teensy
331 decoders. para_mp3dec is based on libmad, para_oggdec requires
332 libvorbisfile.
333 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
334 they are now called para_send and para_recv respectively.
335 - documentation updates
336 - para_gui is themable. For now there is the default theme that
337 looks as before and the simple theme: blue and easy.
338 - gui: audio streaming is now handled by audiod. Time display shows
339 playback time rather than streaming time
340 - slider: update to libzmw-0.2.0
341 - para_krell: fix crash on server shutdown
342 - switch from gzip to bzip2
343
344
345 ----------------------------------------
346 0.1.7 (2005-04-18) "melting penetration"
347 ----------------------------------------
348
349 The main change in this release is clearly the oggvorbis rewrite,
350 but there are also lots of smaller changes. If you intend to use both
351 the mp3 and the ogg plugin, it is recommended to use software mixing,
352 e.g. the dmix plugin which is provided by ALSA.
353
354 - new executables: para_ovsend and para_ovrecv for sending/receiving
355 oggvorbis files via rtp. Requires the open rtp library. Get it at
356 http://www.linphone.org/ortp/
357 - rewrite of the ogg_vorbis core code
358 - configure detects libzmw and, if detected, includes
359 para_slider to the list of binaries to be built by make
360 - server stream writers read from their associated fifo rather
361 than from stdin
362 - slider: two new sliders, lastplayed and numplayed
363 - fix nasty double free bug which caused random segfaults in case of
364 mp3 files with invalid header information
365 - gui: new command line option: --stream_timeout=seconds to
366 deactivate a slot if it is idle for that many seconds (default=`5')
367 - diffstats
368
369
370 ---------------------------------------
371 0.1.6 (2005-03-05) "asymptotic balance"
372 ---------------------------------------
373
374 Only little user-visible changes in this release. Mainly bugfixes and
375 core code cleanup. This is probably the most stable version ever if you
376 stick to mp3...
377
378 - fix several memory leaks
379 - rename default name of mysql database from "music" to "paraslash".
380 Use para_server's --mysql_database option if you do not want to
381 rename your old database.
382 - rework ogg vorbis code
383 - make update command work on mysql servers with LOCAL_INFILE
384 disabled
385 - gui: improved stream I/O (slots)
386 - simplified audio format API
387 - para_pob_ogg is gone
388
389 ------------------------------------
390 0.1.5 (2004-12-31) "opaque eternity"
391 ------------------------------------
392
393 Let's slide gently into the new year.
394
395 - new: para_slider (not built automatically, type "make
396 para_slider" to build). A toy for those who always felt that
397 creating stream definitions is difficult. See screenshots,
398 README and FEATURES for more info.
399 - improved signal handling. Fixes server segfault on SIGHUP
400 for linux kernels newer than Aug 24 2004 and makes para_gui
401 race-free.
402 - reload database tool on SIGHUP
403 - improved help message for sl
404 - do not log "broken pipe" messages as errors. They are
405 perfectly ok.
406 - fix wrong error message on permission errors
407
408 -----------------------------------------
409 0.1.4 (2004-12-19) "tunneling transition"
410 -----------------------------------------
411
412 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
413 Hopefully, most of them got wiped out with this release. Some
414 enhancements went also in.
415
416 - improved error diagnostics for all commands
417 - stradd/picadd: overwrite previous contents if entry already
418 exists, rather than returning errors
419 - stradd: use current stream if invoked without args
420 - faster (and hopefully more stable) ogg-vorbis handling
421 - para_krell: reap children to avoid zombie-flooding in case
422 no server is running
423 - si: report also server pid
424 - server: don't busy-loop if dbtool reports only invalid files.
425 - gui: CTRL+C works again, fix stream_read command line option
426 - fix pic_add, hist
427 - fix mysql dbtool startup in case no database exists
428 - many small fixes and cleanups
429
430 ---------------------------------------
431 0.1.3: (2004-12-10) "vanishing inertia"
432 ---------------------------------------
433
434 Starting from this release, the database tools are integrated in the
435 server binary. This decreases server startup time, reduces code size
436 and speeds up database commands. However, the layout of the underlying
437 mysql database changed only slightly and 0.1.3 should be backwards
438 compatible in that respect.
439
440 Visible changes:
441
442 - If mysql is not detected at compile time, or fails to init
443 at runtime, fall back to the dopey database tool which should
444 always work.
445 - para_dbtool and dbtool.conf are gone. All mysql specific
446 options are read from server.conf and are prefixed by 'mysql_'.
447 - new command: cdt (change database tool)
448 - new command line option: dbtool (choose startup database tool)
449 - The name of current stream is now stored in the database,
450 so paraslash remembers its current stream when restarted.
451 - new command: csp (change stream and play)
452 - para_gui also reports current database tool and server uptime
453
454
455 -------------------------------------------
456 0.1.2: (2004-11-28) "spherical fluctuation"
457 -------------------------------------------
458
459 Point release before the big dbtool changes go in.
460
461 - dbtool: rename ca to cam (copy all meta data). It now also
462 copies numplayed and lastplayed time as well as the picture
463 id.
464 - fix endless-loop-bug caused by mp3 files with invalid header
465
466 -----------------------------------------
467 0.1.1: (2004-11-05) "floating atmosphere"
468 -----------------------------------------
469
470 - gkrellm plugin
471 - new dbtool command: mbox. Browse your sound-file collection
472 with your favorite mail reader.
473 - several small fixes
474
475 -------------------------------------
476 0.1.0: (2204-10-22) "rotating cortex"
477 -------------------------------------
478
479 - fix logging bug for loglevel > VERBOSE
480 - fix skip command
481 - correct timings for vbr mp3s
482 - modular audio format support
483 - ogg-vorbis support (experimental)
484 - new server option: autoplay
485
486 -----------------------------------------
487 0.0.99: (2004-07-25) "harmonic deviation"
488 -----------------------------------------
489
490 - rename projectname from icc to paraslash (play, archive, rate
491 and stream large audio sets happily)
492 - paraslash is no longer restricted to one particular audio
493 streaming software
494 - new dbtool commands (stradd, strq, strdel) for easy stream
495 managment w/o configuration file. That obsoletes stream_defs
496 file/config option for dbtool.
497 - picadd accepts jpeg data from stdin
498 - new server commands: ps (select previous stream), sc (song change)
499 - new default pictures for sdl_gui
500 - gui: new key_map option for binding commands and internal
501 functions to arbitrary keys, nice help screen, rip out
502 soundcard/linux specific stuff, avoid noise artefacts while jumping,
503 show silly logo on startup
504 - new executables: para_fade for fading volume, para_dbadm for
505 manipulating attributes
506 - cdb adds _all_ tables to mysql database
507 - revised and beautified documentation
508 - sample dbtool rewritten in C
509 - autoconf
510
511 ---------------------------------------------
512 0.0.98: (2003-12-26) "incremental smoothness"
513 ---------------------------------------------
514
515 - kick icecast in favour of poc. That removes some races and reduces
516 core code considerably.
517 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
518 give finer info on afs' status.
519 - gui can start decoder (see config options). Further new gui
520 commands: refresh (^L), jmp (F1-F10)
521 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
522 terminates gui. This fixes dead instances consuming memory
523 continuously.
524 - new dbtool command: verb for sending verbatim sql queries.
525 - fix pid_list races (by removing pid_list)
526 - codename funnies
527
528 --------------------
529 0.0.97: (2003-10-26)
530 --------------------
531
532 - installation prefix now defaults to /usr/local
533 - new commands for gui: snozze, sleep and reread config
534 - config file for gui and sdl_gui
535 - fix problems with filenames containing funny characters
536 (reported by Thomas Forell)
537 - improved signal handling for gui, now it rereads conf on SIGHUP
538 - new dbtool command: cdb (create database)
539 - switch from argtable to gengetopt
540 - major code cleanup and speed improvements
541 - fix several potential buffer overflows
542 - many small fixes and cleanups
543
544 -------------------
545 0.0.96 (2003-08-30)
546 -------------------
547
