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 - update to gengetopt-2.20
15
16 --------------------------------------
17 0.2.16 (2007-04-05) "neural discharge"
18 --------------------------------------
19
20 The main change in this release is the major audio format handler
21 cleanup which removes some similar/duplicate code and makes it easier
22 to implement plugins for other audio formats. Of course, the usual mix
23 of other improvements/changes/bugfixes also made it into the release.
24
25 - simplified audio format handlers (most of the handling functions
26 were moved one layer up to the virtual streaming system).
27 - para_server uses mmap to read audio files
28 - repositioning of mp3 streams is much faster, in particular for
29 jumping near the end of large mp3 files.
30 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
31 and AFS_WRITE.
32 - fix a bug in para_filter that caused decoding of aac files
33 to start only after a few seconds.
34 - fix osx_writer hangs
35 - simplified dccp code (thanks to Gerrit Renker)
36 - the compress filter works also on big endian systems (ppc)
37
38 -----------------------------------------
39 0.2.15 (2007-02-16) "inductive resonance"
40 -----------------------------------------
41
42 Minor improvements, more documentation and a bunch of bug fixes.
43
44 - para_server: The server.users file is only read once on server
45 startup rather than for each connection
46 - mp3dec: Fix decoding of corrupt mp3 files
47 - afs (audio file sender) is now called vss (virtual streaming
48 system). Consequently, the permission flags specified in
49 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
50 become VSS_READ and VSS_WRITE respectively.
51 - para_audiod/para_filter: Fix a bug that caused the last chunk
52 of audio data not being written under certain circumstances
53 - audiod: compute the difference of server time and local time
54 correctly
55 - para_server/para_audiod: Fix some memory leaks
56 - documentation improvements
57 - configure.ac: fix checks for para_krell
58 - new man pages
59
60 -------------------------------------------
61 0.2.14 (2006-10-15) "transient singularity"
62 -------------------------------------------
63
64 The only major enhancement of this version is the osx writer which completes
65 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
66 until now for reasons beyond the scope of this changelog entry.
67
68 - new output plugin for Mac Os: the osx writer
69 - rename configure command line options from --enable-xxx-headers to
70 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
71 - configure: new command line options: --with-mad-headers,
72 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
73 - some robustness fixes
74 - dymamic audio format recognition for audiod
75 - para_server: new command line option: --autoplay_delay
76 - para_audiod: new command line option: --clock_diff_count
77
78 ---------------------------------------
79 0.2.13 (2006-07-14) "sonic convolution"
80 ---------------------------------------
81
82 A bunch of new features and core changes.
83
84 - the new paraslash scheduler, short and sweet.
85 - Support for m4a/mp4 files via the new aac audio format
86 handler/filter (requires libfaad).
87 - each writer has its own command line parser, just like
88 para_recv and para_filter.
89 - para_client and para_audioc use the error subsystem
90 - writers are integrated in para_audiod (currently linux-only)
91 - para_client is integrated in para_audiod
92 - random/playlist selector: improved info strings
93 - new audiod commands: tasks, kill
94 - update to libortp-0.10.1
95 - para_fade: wake time defaults to 8 hours from now
96 - update to autoconf-2.60
97
98
99 ------------------------------------------
100 0.2.12 (2006-05-12) "oriented abstraction"
101 ------------------------------------------
102
103 Many user-visible changes in this release and lots of new
104 features:
105
106
107 - the new optional dccp sender/receiver. It uses the datagram
108 congestion control protocol. You'll need a fairly new kernel
109 for this.
110 - paraslash works on Mac OS X (thanks to Gerd Becker)
111 - para_play renamed to para_write
112 - modular output plugin design (writers) for para_write
113 - new file_writer output plugin for para_write
114 - compress filter speed improvements
115 - update to libortp-0.9.1
116 - update to gengetopt-2.17rc
117 - para_client no longer depends on libreadline (as the
118 code for the interactive mode was removed).
119 - gcc-2-95 is no longer a supported compiler. It may still
120 work, but it gets no more testing.
121 - the tarball no longer contains the screenshot images which
122 reduces its size quite a bit.
123 - configure: new command line options: --enable-mysql-headers
124 and --enable-mysql-libs
125
126 ------------------------------------
127 0.2.11 (2006-03-11) "atomic duality"
128 ------------------------------------
129
130 Here it is, the first paraslash release developed with git. There
131 are fairly many user-visible changes in this release. As two out of
132 the three "database tools" of paraslash don't use a database at all,
133 they are now called "audio file selectors" instead.
134
135
136 - the cdt command (change database tool) becomes chs (change
137 selector)
138 - no more colon separators: The syntax of some options of
139 para_audiod and para_filter have changed. Use --help for
140 more info (and some examples).
141 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
142 - switch from cvs to git (should've done that earlier)
143 - the new ipc subsystem
144 - new audio file selector: playlist
145 - para_server: the dopey selector is now called "random",
146 and is the default selector. Use the --selector option to
147 choose another selector at startup, or the chs command to
148 change the selector at runtime.
149 - X86_64 fixes (thanks to Steffen Klassert)
150 - para_play fixes
151
152
153 --------------------------------------
154 0.2.10 (2006-02-17) "cyclic attractor"
155 --------------------------------------
156
157 Huge documentation update, a scrollable window for para_gui, ortp
158 improvements, and of course many small fixes not mentioned here.
159 The diffstat below is rather misleading as most insertions are due
160 to the new source documentation.
161
162 - autoconf cleanup
163 - para_server also uses the new error subsystem
164 - lots of new documentation (UTSL)
165 - gui improvements:
166 - keysyms for cursor keys and for next/previous page keys
167 - scrollable output window
168 - new internal commands: scroll up/down, page up/down
169 - fix color of command output.
170 - ortp: the --chunk_time and --header flags are no longer needed
171 for para_recv/para_audiod as this information is now encoded in
172 each rtp packet sent by para_server.
173
174
175 -------------------------------------------
176 0.2.9 (2006-01-24) "progressive turbulence"
177 -------------------------------------------
178
179 Internal audiod receivers/filters, the new error subsystem and
180 a lot of small improvements.
181
182 - para_recv and para_filter are integrated into the para_audiod
183 binary, i.e. audiod no longer spawns a new process for
184 each receiver/filter. As para_recv and para_filter might be
185 useful as standalone programs, they still get built (linked
186 against the same object files that are also used for audiod).
187 - further ortp timing improvements should reduce the CPU usage
188 of the ortp receiver.
189 - improved audio grabbing. The 'grab' command of para_audiod
190 has its own set of command line options. Read the output of
191 "para_audioc help grab" for more info.
192 - oggdec: configurable input prebuffer size.
193 - the new error subsystem gives better error diagnostics
194 and reduces code size.
195
196
197 -----------------------------------------
198 0.2.8 (2006-01-02) "dynamic accumulation"
199 -----------------------------------------
200
201 The new modular filter design and the para_play-hangs bugfix.
202
203 - new executable: para_filter. It combines para_mp3dec,
204 para_oggdec and para_compress. It also adds a further filter
205 type, wav, that just inserts a wave header at the desired point
206 of the filter chain. All 'piping' is done in-memory (i.e. no
207 read/write operations are used).
208 - para_play: fix a stupid bug that caused it to hang under
209 certain circumstances.
210
211
212 -------------------------------------------
213 0.2.7 (2006-12-27) "transparent invariance"
214 -------------------------------------------
215
216 Not many user-visible changes but a fair amount of internal improvements.
217
218
219 - The http sender buffers data if it can not be sent
220 out immediately (because the socket is not writable). This
221 should prevent para_server from shutting down the connection
222 too early on a loaded network.
223 - para_play also prebuffers data if it is told to start at a
224 future time by the --start_time option.
225 - The return of para_recv: It combines para_ortp_recv and
226 para_http_recv. Use the --receiver option to switch between
227 the two. para_recv builds without libortp, but contains
228 only the http receiver in this case.
229 - update to ortp 0.8.1. As this ortp release contains incompatible
230 changes, para_recv-0.2.7 won't link against older ortp libs.
231 - improved ortp timings.
232 - use of gcc-extensions that #define away for non-gcc and
233 gcc < 3.0.
234
235
236 -------------------------------------------
237 0.2.6 (2005-10-29) "recursive compensation"
238 -------------------------------------------
239
240 Transparent session encryption (uses openssl's Alleged RC4 cipher),
241 the internal find command and several other improvements and cleanups.
242
243 - Encrypt the session if encryption is requested by the client
244 (default for para_client 0.2.6). This is backwards
245 compatible, so older clients can still connect to para_server
246 0.2.6. Use the new client option --plain to request an
247 uncrypted session (off by default, must be set to on in
248 order to connect to para_server 0.2.x with 0 <= x <= 5).
249 - para_server uses an internal function to locate audio files
250 rather than calling find(1). The server option
251 --mysql_audio_file_dir replaces --mysql_find_cmd.
252 - documentation update
253 - man pages
254 - header file cleanup
255 - para_client code cleanup
256 - para_gui: faster display of output of display commands
257
258
259 ------------------------------------------
260 0.2.5 (2005-10-13) "aggressive resolution"
261 ------------------------------------------
262
263 This release adds internal senders, i.e. no more external programs are
264 spawned for sending out the audio data. There are two different senders
265 available: The http sender and the ortp sender (former para_send which
266 is no longer needed).
267
268 The new sender code has a plugin-like design so it can be easily
269 extended should there be be any future need for supporting another
270 network streaming protocol. All senders are completely independent of
271 each other. In particular, the http and the ortp sender can operate
272 in parallel.
273
274 - new server command: sender to control senders at runtime.
275 Read the output of "para_server -h" and "para_client help
276 sender" for more information.
277 - para_recv renamed to para_ortp_recv
278 - new executable: para_http_recv, a simple command line
279 http receiver.
280 - major afs/mp3/ogg code simplifications due to internal
281 senders.
282 - ogg timing improvements
283 - fix several minor memory leaks (found by valgrind)
284 - empty stream definitions work again
285 - com_ne(): ignore errors on remove
286 - audiod: fix segfault on server restart
287
288
289 ---------------------------------------
290 0.2.4 (2005-09-21) "toxic anticipation"
291 ---------------------------------------
292
293 Several small improvements, fixes and the new grab command.
294
295 - audiod:
296 - new command: "grab" to grab the output of the stream reader
297 or any filters. Read the output of "para_audioc help grab"
298 for more information.
299 - fix memory leak
300 - code cleanup
301 - audioc: new command line option: --bufsize to specify a
302 buffer size different from the default size 8192.
303 - improved error diagnostics for para_play.
304 - new configure option: --enable-ssldir so search for openssl in
305 non-standard places
306 - sdl_gui: Make it look nice again for 1024x768
307 - server: report total size of memory allocated with sbrk by malloc,
308 new command line option: --announce_time
309
310
311 -----------------------------------------
312 0.2.3 (2005-09-01) "hydrophilic movement"
313 -----------------------------------------
314
315 Two new executables and major feature enhancements.
316
317 - audiod filters: It is now possible to specify arbitrary many
318 (including none) filters for each supported audio
319 format. This can be used e.g. for normalizing volume,
320 transforming or grabbing the audio stream, or for using
321 visualizers. Read the output of "para_audiod -h" for the
322 syntax of the new --filter_cmd option.
323 - new executable: para_play, a tiny alsa player. It
324 can play wave files or raw pcm (16 bit little endian)
325 from stdin.
326 - new executable: para_compress, a dynamic range compressor
327 intended to keep audio output at a consistent volume. Derived
328 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
329 - audiod: New option: --stream_delay. This can be used in
330 a local network to syncronize the audio output of all
331 clients that play the same stream.
332
333
334 ------------------------------------------
335 0.2.2 (2005-08-19) "tangential excitation"
336 ------------------------------------------
337
338 Mostly internal changes in this release, but also some new commands
339 for the mysql database tool.
340
341 - cleanup exec.c, fix para_exec bug
342 - compile time loglevel (log messages below the given level
343 won't be compiled in, which reduces the size of the
344 resulting binaries)
345 - new log macros that shorten the size of the source code.
346 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
347 to send only zeros. With this workaround, para_audioc works
348 again.
349 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
350 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
351 (new entry), "snp" (set numplayed). Read the manual for more
352 information.
353
354
355 ---------------------------------------
356 0.2.1 (2005-08-15) "surreal experience"
357 ---------------------------------------
358
359 Here comes paraslash-0.2.1. It contains a couple of new features and,
360 surprise, only minor bug fixes.
361
362 - kill noisy mp3 debug message
363 - cleanup of the build system
364 - para_server and para_client directly use the crypto routines
365 of the openssl library rather than invoking the openssl command
366 line utitlity
367 - server/audiod: new option --user to switch to the given user
368 when invoked as root. Read the output of "para_server -h" for
369 more information.
370 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
371 status. Default: "para_audioc stat"
372 - sdl_gui: new option --pic_cmd to be used to download the picture.
373 Default: "para_client pic"
374 - audiod: 5 slots ought to be enough for everybody
375 - audiod: new status item: Uptime, kill hup command
376
377
378
379 ------------------------------------------
380 0.2.0 (2005-08-06) "distributed diffusion"
381 ------------------------------------------
382
383 After several month of increased development activity, paraslash-0.2.0
384 has arrived. It contains many new features and is much more
385 self-contained than the old 0.1.x series. Enjoy!
386
387
388 - para_server: fix hang on song change and crash on sighup.
389 Speed up mysql queries. The DIR_LIKE macro is gone.
390 - new executables: para_audiod, the local audio daemon that
391 starts playback (uses SCM_CREDENTIALS socket magic) and
392 para_audioc, the corresponding client.
393 - new executables: para_mp3dec/para_oggdec, two really teensy
394 decoders. para_mp3dec is based on libmad, para_oggdec requires
395 libvorbisfile.
396 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
397 they are now called para_send and para_recv respectively.
398 - documentation updates
399 - para_gui is themable. For now there is the default theme that
400 looks as before and the simple theme: blue and easy.
401 - gui: audio streaming is now handled by audiod. Time display shows
402 playback time rather than streaming time
403 - slider: update to libzmw-0.2.0
404 - para_krell: fix crash on server shutdown
405 - switch from gzip to bzip2
406
407
408 ----------------------------------------
409 0.1.7 (2005-04-18) "melting penetration"
410 ----------------------------------------
411
412 The main change in this release is clearly the oggvorbis rewrite,
413 but there are also lots of smaller changes. If you intend to use both
414 the mp3 and the ogg plugin, it is recommended to use software mixing,
415 e.g. the dmix plugin which is provided by ALSA.
416
417 - new executables: para_ovsend and para_ovrecv for sending/receiving
418 oggvorbis files via rtp. Requires the open rtp library. Get it at
419 http://www.linphone.org/ortp/
420 - rewrite of the ogg_vorbis core code
421 - configure detects libzmw and, if detected, includes
422 para_slider to the list of binaries to be built by make
423 - server stream writers read from their associated fifo rather
424 than from stdin
425 - slider: two new sliders, lastplayed and numplayed
426 - fix nasty double free bug which caused random segfaults in case of
427 mp3 files with invalid header information
428 - gui: new command line option: --stream_timeout=seconds to
429 deactivate a slot if it is idle for that many seconds (default=`5')
430 - diffstats
431
432
433 ---------------------------------------
434 0.1.6 (2005-03-05) "asymptotic balance"
435 ---------------------------------------
436
437 Only little user-visible changes in this release. Mainly bugfixes and
438 core code cleanup. This is probably the most stable version ever if you
439 stick to mp3...
440
441 - fix several memory leaks
442 - rename default name of mysql database from "music" to "paraslash".
443 Use para_server's --mysql_database option if you do not want to
444 rename your old database.
445 - rework ogg vorbis code
446 - make update command work on mysql servers with LOCAL_INFILE
447 disabled
448 - gui: improved stream I/O (slots)
449 - simplified audio format API
450 - para_pob_ogg is gone
451
452 ------------------------------------
453 0.1.5 (2004-12-31) "opaque eternity"
454 ------------------------------------
455
456 Let's slide gently into the new year.
457
458 - new: para_slider (not built automatically, type "make
459 para_slider" to build). A toy for those who always felt that
460 creating stream definitions is difficult. See screenshots,
461 README and FEATURES for more info.
462 - improved signal handling. Fixes server segfault on SIGHUP
463 for linux kernels newer than Aug 24 2004 and makes para_gui
464 race-free.
465 - reload database tool on SIGHUP
466 - improved help message for sl
467 - do not log "broken pipe" messages as errors. They are
468 perfectly ok.
469 - fix wrong error message on permission errors
470
471 -----------------------------------------
472 0.1.4 (2004-12-19) "tunneling transition"
473 -----------------------------------------
474
475 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
476 Hopefully, most of them got wiped out with this release. Some
477 enhancements went also in.
478
479 - improved error diagnostics for all commands
480 - stradd/picadd: overwrite previous contents if entry already
481 exists, rather than returning errors
482 - stradd: use current stream if invoked without args
483 - faster (and hopefully more stable) ogg-vorbis handling
484 - para_krell: reap children to avoid zombie-flooding in case
485 no server is running
486 - si: report also server pid
487 - server: don't busy-loop if dbtool reports only invalid files.
488 - gui: CTRL+C works again, fix stream_read command line option
489 - fix pic_add, hist
490 - fix mysql dbtool startup in case no database exists
491 - many small fixes and cleanups
492
493 ---------------------------------------
494 0.1.3: (2004-12-10) "vanishing inertia"
495 ---------------------------------------
496
497 Starting from this release, the database tools are integrated in the
498 server binary. This decreases server startup time, reduces code size
499 and speeds up database commands. However, the layout of the underlying
500 mysql database changed only slightly and 0.1.3 should be backwards
501 compatible in that respect.
502
503 Visible changes:
504
505 - If mysql is not detected at compile time, or fails to init
506 at runtime, fall back to the dopey database tool which should
507 always work.
508 - para_dbtool and dbtool.conf are gone. All mysql specific
509 options are read from server.conf and are prefixed by 'mysql_'.
510 - new command: cdt (change database tool)
511 - new command line option: dbtool (choose startup database tool)
512 - The name of current stream is now stored in the database,
513 so paraslash remembers its current stream when restarted.
514 - new command: csp (change stream and play)
515 - para_gui also reports current database tool and server uptime
516
517
518 -------------------------------------------
519 0.1.2: (2004-11-28) "spherical fluctuation"
520 -------------------------------------------
521
522 Point release before the big dbtool changes go in.
523
524 - dbtool: rename ca to cam (copy all meta data). It now also
525 copies numplayed and lastplayed time as well as the picture
526 id.
527 - fix endless-loop-bug caused by mp3 files with invalid header
528
529 -----------------------------------------
530 0.1.1: (2004-11-05) "floating atmosphere"
531 -----------------------------------------
532
533 - gkrellm plugin
534 - new dbtool command: mbox. Browse your sound-file collection
535 with your favorite mail reader.
536 - several small fixes
537
538 -------------------------------------
539 0.1.0: (2204-10-22) "rotating cortex"
540 -------------------------------------
541
542 - fix logging bug for loglevel > VERBOSE
543 - fix skip command
544 - correct timings for vbr mp3s
