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