NEWS update.
[paraslash.git] / NEWS
1 -------------------------------------------------
2 0.4.5 (to be announced) "symmetric randomization"
3 -------------------------------------------------
4
5 Mainly bug fixes and the var_fec_slices patch set.
6
7 - Contains a fix for an invalid-free-bug in the ogg audio format
8 handler code.
9 - Switching off the DCCP sender works again.
10 - para_audiod handles crashes of para_server more robustly.
11 - Internal scheduler cleanups.
12 - reduced latency due to variable sized FEC slices.
13 - Improved documentation and error diagnostics.
14
15 ------------------------------------------
16 0.4.4 (2010-08-06) "persistent regularity"
17 ------------------------------------------
18
19 Support for yet another audio format, para_write improvements and
20 bug fixes.
21
22 - Support for the speex codec.
23 - Support for sample formats other than 16 bit little endian.
24 - error2.h is now created by a perl script which speeds up configure
25 considerably.
26 - Fix a bug in the aac decoder which could lead to segfaults in
27 para_filter/para_audiod.
28 - Fixes for autoconf-2.66.
29
30 ----------------------------------------
31 0.4.3 (2010-07-05) "imaginary radiation"
32 ----------------------------------------
33
34 Many improvements for the DCCP and the UDP transport, the new user
35 manual and the usual mix of bug fixes and internal improvements.
36
37 - FEC support for the DCCP sender (Gerrit Renker). The new
38 --dccp_max_slice_size, --dccp_data_slices_per_group and
39 --dccp_slices_per_group options can be used to set the FEC
40 parameters for the DCCP transport.
41 - DNS lookups for UDP targets (Gerrit Renker).
42 - The new user manual replaces the README, README.afs, REQUIREMENTS
43 and INSTALL documents.
44 - Fix an end-of-file detection bug in the oggdec filter.
45 - The new nonblock API.
46 - Both options of the oggdec filter have been removed.
47 - New debug mode for the internal scheduler.
48
49 ------------------------------------------
50 0.4.2 (2010-04-23) "associative expansion"
51 ------------------------------------------
52
53 It's been some time since the last release, but finally here is
54 paraslash-0.4.2. The bulk of the changes comes from the new buffer
55 tree API, but there are changes all over the tree. Mainly performance
56 and usability improvements, but also quite some bug fixes.
57
58 - The new buffer tree API.
59 - DCCP: Support for CCID negotiation (Gerrit Renker).
60 - UDP robustness fixes.
61 - The --bufsize option for mp3dec is gone as it no longer makes sense
62 for the new buffer tree API.
63 - Fix audible buffer underruns for wma streams.
64 - The alsa writer no longer prints meaningless underrun durations.
65 - audiod: Defaults work also for udp streams. If no filter is
66 given for an audio format that is received via upd, fecdec is
67 automatically added as the first filter (along with the decoder).
68
69 ---------------------------------------
70 0.4.1 (2009-12-22) "concurrent horizon"
71 ---------------------------------------
72
73 Support for another audio format, minor feature enhancements and lots of bug
74 fixes. All fixes that have been accumulated in the maint branch (in particular
75 those mentionened in the 0.3.6 release notes) appear in this release as well.
76
77 - wma support.
78 - new afh option: --human to activate human-readable output.
79 - new server/audiod option: --log-timing to print timing information.
80 - build system improvements.
81 - source code documentation updates.
82
83 -------------------------------------
84 0.3.6 (2009-12-07) "cubic continuity"
85 -------------------------------------
86
87 Quite a few bugs have been found and fixed since 0.3.5, so here's
88 another 0.3.x release. No new features.
89
90 - Always check return value of malloc().
91 - ogg vorbis/FEC: Do not write garbage after the audio file header.
92 - exit if root privileges could not be dropped.
93 - FEC: Fix computation of extra slices.
94 - oss: Fix check for empty input buffer.
95 - Avoid buffer underruns due to filter chain output buffer constraints.
96 - server: Fix assignment of afs_pid.
97 - Don't panic if the afs database contains unknown audio formats.
98 - http/dccp: Do not send the audio file header twice.
99 - FEC: Timing improvements.
100
101 ----------------------------------------------
102 0.4.0 (2009-11-10) "simultaneous independence"
103 ----------------------------------------------
104
105 Two significant changes which require the new version number: The
106 improved authentication dialog and the fact that the database code
107 has been moved to a library, libosl. To use the new version, you have
108 to generate new RSA keys, see INSTALL for details. A shell script is
109 provided for conversion of the 0.3 database to the new 0.4 format.
110
111 - stronger crypto for client authentication
112 - the database code has been moved to a library
113 - improved status item handling
114 - cleanup of the build system
115 - The "-V" option now also prints the git version
116 - the new parser-friendly listing mode for the ls and stat commands
117 - mandatory rc4 encryption
118 - major audio format handler cleanups
119 - (id3,...) tags are no longer stored as a combined string in the database
120 - new mood methods: artist_matches, title_matches, comment_matches,
121 album_matches, year_maches, year.
122
123 --------------------------------------------
124 0.3.5 (2009-09-21) "symplectic separability"
125 --------------------------------------------
126
127 Full client support for *BSD Unixes, complete re-write of the ogg
128 vorbis audio format handler, various improvements all over the place
129 and the usual mix of bugfixes. This release marks the end of the 0.3
130 series if no serious problems show up.
131
132 - the new oss writer (supported on *BSD and Linux)
133 - rewrite of the ogg vorbis audio format handler. It's
134 recommended to replace the chunk tables of existing ogg
135 vorbis files in the afs database by re-adding these files
136 with "add -f".
137 - support for netmask subsets (Gerrit Renker)
138 - the new prebuffer filter
139 - improved signal handling
140 - variable fec output buffer size
141 - improved FEC timing fixes audible buffer underruns in UDP mode
142 - --log_color actually works
143 - new ls option: -d (print dates as seconds after the epoch)
144 - update to gengetopt 2.22.2
145 - support for RSA keys of size > 512 bits
146 - new option "mixer_channel" for para_fade
147
148 -----------------------------------------
149 0.3.4 (2009-05-07) "elliptic inheritance"
150 -----------------------------------------
151
152 The new udp sender, forward error correction, colored logs and various
153 other improvements. As the udp sender does not depend on any special
154 libraries, it is built unconditionally.
155
156 - The udp sender replaces the ortp sender. The new code uses forward
157 error correction to protect against packet losses. Many thanks to
158 Gerrit Renker for providing ipv6 support.
159 - The default port for udp streaming now defaults to 8000, like
160 for the http and the dccp senders/receivers.
161 - Loglevels are now specified as symbolic names, e.g.
162 "--loglevel info".
163 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
164 - para_server/para_audiod: Color support for log messages.
165 - new options for mp3dec: --ignore-crc, --bufsize
166 - new audiod option: --config-file.
167 - gengetopt cleanups.
168 - Improved help/man pages: The documentation of para_audiod,
169 para_recv, para_filter and para_write now also contains
170 all options of the available receivers/filters/writers. The
171 man page of para_fade contains a description of the different
172 modes of operation.
173 - More source code documentation.
174 - vss timing fixes.
175
176 --------------------------------------------
177 0.3.3 (2008-12-01) "axiomatic perspectivity"
178 --------------------------------------------
179
180 Internal code cleanups, bug fixes, improved tag handling and the new
181 amplification filter.
182
183 - para_server uses the generic scheduling code.
184 - overhaul of the virtual streaming system.
185 - mp3: id3 version 2 support via libid3tag (optional)
186 - ogg: vorbis comment support.
187 - aac meta info support.
188 - mp3 audio format handler cleanups.
189 - new filter: "amp" to amplify the amplitude of the audio stream
190 - new status item/database entry: amplification. It is
191 used by the amp filter to pre-amplify the audio stream.
192 - fix a close-without-open bug in para_write.
193 - fix a bug in com_init() which was introduced in 0.3.2.
194 - better error diagnostics for para_client.
195
196 -----------------------------------------
197 0.3.2 (2008-04-11) "probabilistic parity"
198 -----------------------------------------
199
200 The new para_afh executable, scheduling and documentation improvements.
201
202 - new ls option: -lc (list chunk table)
203 - new executable: para_afh, the stand-alone audio file handler tool
204 - afs commands can send output more than SHMMAX (32MB on Linux). This
205 also reduces the memory usage of commands that produce large amounts
206 of output.
207 - major scheduler and audiod cleanups.
208 - more detailed and much nicer man pages.
209
210 ---------------------------------------
211 0.3.1 (2008-02-23) "liquid interaction"
212 ---------------------------------------
213
214 A mix of cleanups, bug fixes, improvements, and some new features. No
215 significant changes to the new database (osl) code, which is generally
216 a good sign.
217
218 - Share some similar/duplicate code between the http and the
219 dccp sender.
220 - Generic access control lists for paraslash senders.
221 - dccp sender: Access control lists, connection limiting and support
222 for the allow,deny,on,off,help sender commands.
223 - The default dccp port changed from 5001 to 8000 (suggested by
224 Gerrit Renker).
225 - para_server starts even if not all public keys could be loaded.
226 - Audiod performance improvements.
227 - fix a bug in the "off" command of the http sender.
228 - fix some fd and memory leaks.
229 - Update to gengetopt-2.22.
230
231 -------------------------------------
232 0.3.0 (2008-01-12) "solar saturation"
233 -------------------------------------
234
235 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
236
237
238 Usually one might expect lots of new features AND a big increase in size
239 for a major release like this.
240
241 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
242 ever. The decrease in size is mostly due to the removal of some
243 graphical tools (which were only quick hacks anyway). But also the
244 fact that the mysql code is gone cuts down the size a bit.
245
246 Being independent of mysql comes at a cost: The fact that paraslash
247 now contains its own database (the object storage layer, osl) increases
248 the (stripped) binary size of para_server by ~50K on i386.
249
250 - no more restrictions on unique basenames.
251 - independent of mysql: The new self-contained object
252 storage layer (osl) replaces the mysql database.
253 - New executable para_fsck: Check integrity of osl tables.
254 - Lyrics support.
255 - Reliable audio file move/rename detection.
256 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
257 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
258 Solaris (sparc64).
259 - the new osl-based audio file selector (afs) replaces the random,
260 the playlist and the mysql selector of paraslash-0.2.x.
261 - IPv6 support (thanks to Gerrit Renker).
262 - paraslash-0.2.x streams are now called "moods". Writing
263 0.3.x-mood definitions should be both easier and more
264 powerful than writing 0.2.x-stream definitions.
265 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
266 been removed. The world is a better place without them. However,
267 para_gui is still there.
268 - afs tracks audio file selection also in playlist mode.
269 - few easy-to-use afs commands replace the many not-so-easy-to-use
270 mysql commands (and are available also in playlist mode).
271 - Improved error subsystem.
272 - The earth-shaking new logo.
273
274 -----------------------------------------
275 0.2.17 (2007-11-20) "isotropic threshold"
276 -----------------------------------------
277
278 Mainly bugfixes and cleanups in this version which marks the end of
279 the 0.2.x series if no serious bugs show up after the release.
280
281 - mysql_selector: fix a locking bug.
282 - universal chunk queueing.
283 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
284 to Gerrit Renker).
285 - be more carful wrt. signed vs. unsigned argument passing.
286 - cleanup error.h and fix some references to invalid error
287 codes.
288 - update to gengetopt-2.21.
289 - update to ortp-0.13.1.
290 - autoconf: extend checks for headers, library functions and
291 compiler characteristics.
292 - Fix streaming of large mp3 files.
293 - Fix an off-by-one bug in playlist handling.
294
295 --------------------------------------
296 0.2.16 (2007-04-05) "neural discharge"
297 --------------------------------------
298
299 The main change in this release is the major audio format handler
300 cleanup which removes some similar/duplicate code and makes it easier
301 to implement plugins for other audio formats. Of course, the usual mix
302 of other improvements/changes/bugfixes also made it into the release.
303
304 - simplified audio format handlers (most of the handling functions
305 were moved one layer up to the virtual streaming system).
306 - para_server uses mmap to read audio files
307 - repositioning of mp3 streams is much faster, in particular for
308 jumping near the end of large mp3 files.
309 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
310 and AFS_WRITE.
311 - fix a bug in para_filter that caused decoding of aac files
312 to start only after a few seconds.
313 - fix osx_writer hangs
314 - simplified dccp code (thanks to Gerrit Renker)
315 - the compress filter works also on big endian systems (ppc)
316
317 -----------------------------------------
318 0.2.15 (2007-02-16) "inductive resonance"
319 -----------------------------------------
320
321 Minor improvements, more documentation and a bunch of bug fixes.
322
323 - para_server: The server.users file is only read once on server
324 startup rather than for each connection
325 - mp3dec: Fix decoding of corrupt mp3 files
326 - afs (audio file sender) is now called vss (virtual streaming
327 system). Consequently, the permission flags specified in
328 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
329 become VSS_READ and VSS_WRITE respectively.
330 - para_audiod/para_filter: Fix a bug that caused the last chunk
331 of audio data not being written under certain circumstances
332 - audiod: compute the difference of server time and local time
333 correctly
334 - para_server/para_audiod: Fix some memory leaks
335 - documentation improvements
336 - configure.ac: fix checks for para_krell
337 - new man pages
338
339 -------------------------------------------
340 0.2.14 (2006-10-15) "transient singularity"
341 -------------------------------------------
342
343 The only major enhancement of this version is the osx writer which completes
344 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
345 until now for reasons beyond the scope of this changelog entry.
346
347 - new output plugin for Mac Os: the osx writer
348 - rename configure command line options from --enable-xxx-headers to
349 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
350 - configure: new command line options: --with-mad-headers,
351 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
352 - some robustness fixes
353 - dymamic audio format recognition for audiod
354 - para_server: new command line option: --autoplay_delay
355 - para_audiod: new command line option: --clock_diff_count
356
357 ---------------------------------------
358 0.2.13 (2006-07-14) "sonic convolution"
359 ---------------------------------------
360
361 A bunch of new features and core changes.
362
363 - the new paraslash scheduler, short and sweet.
364 - Support for m4a/mp4 files via the new aac audio format
365 handler/filter (requires libfaad).
366 - each writer has its own command line parser, just like
367 para_recv and para_filter.
368 - para_client and para_audioc use the error subsystem
369 - writers are integrated in para_audiod (currently linux-only)
370 - para_client is integrated in para_audiod
371 - random/playlist selector: improved info strings
372 - new audiod commands: tasks, kill
373 - update to libortp-0.10.1
374 - para_fade: wake time defaults to 8 hours from now
375 - update to autoconf-2.60
376
377
378 ------------------------------------------
379 0.2.12 (2006-05-12) "oriented abstraction"
380 ------------------------------------------
381
382 Many user-visible changes in this release and lots of new
383 features:
384
385
386 - the new optional dccp sender/receiver. It uses the datagram
387 congestion control protocol. You'll need a fairly new kernel
388 for this.
389 - paraslash works on Mac OS X (thanks to Gerd Becker)
390 - para_play renamed to para_write
391 - modular output plugin design (writers) for para_write
392 - new file_writer output plugin for para_write
393 - compress filter speed improvements
394 - update to libortp-0.9.1
395 - update to gengetopt-2.17rc
396 - para_client no longer depends on libreadline (as the
397 code for the interactive mode was removed).
398 - gcc-2-95 is no longer a supported compiler. It may still
399 work, but it gets no more testing.
400 - the tarball no longer contains the screenshot images which
401 reduces its size quite a bit.
402 - configure: new command line options: --enable-mysql-headers
403 and --enable-mysql-libs
404
405 ------------------------------------
406 0.2.11 (2006-03-11) "atomic duality"
407 ------------------------------------
408
409 Here it is, the first paraslash release developed with git. There
410 are fairly many user-visible changes in this release. As two out of
411 the three "database tools" of paraslash don't use a database at all,
412 they are now called "audio file selectors" instead.
413
414
415 - the cdt command (change database tool) becomes chs (change
416 selector)
417 - no more colon separators: The syntax of some options of
418 para_audiod and para_filter have changed. Use --help for
419 more info (and some examples).
420 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
421 - switch from cvs to git (should've done that earlier)
422 - the new ipc subsystem
423 - new audio file selector: playlist
424 - para_server: the dopey selector is now called "random",
425 and is the default selector. Use the --selector option to
426 choose another selector at startup, or the chs command to
427 change the selector at runtime.
428 - X86_64 fixes (thanks to Steffen Klassert)
429 - para_play fixes
430
431
432 --------------------------------------
433 0.2.10 (2006-02-17) "cyclic attractor"
434 --------------------------------------
435
436 Huge documentation update, a scrollable window for para_gui, ortp
437 improvements, and of course many small fixes not mentioned here.
438 The diffstat below is rather misleading as most insertions are due
439 to the new source documentation.
440
441 - autoconf cleanup
442 - para_server also uses the new error subsystem
443 - lots of new documentation (UTSL)
444 - gui improvements:
445 - keysyms for cursor keys and for next/previous page keys
446 - scrollable output window
447 - new internal commands: scroll up/down, page up/down
448 - fix color of command output.
449 - ortp: the --chunk_time and --header flags are no longer needed
450 for para_recv/para_audiod as this information is now encoded in
451 each rtp packet sent by para_server.
452
453
454 -------------------------------------------
455 0.2.9 (2006-01-24) "progressive turbulence"
456 -------------------------------------------
457
458 Internal audiod receivers/filters, the new error subsystem and
459 a lot of small improvements.
460
461 - para_recv and para_filter are integrated into the para_audiod
462 binary, i.e. audiod no longer spawns a new process for
463 each receiver/filter. As para_recv and para_filter might be
464 useful as standalone programs, they still get built (linked
465 against the same object files that are also used for audiod).
466 - further ortp timing improvements should reduce the CPU usage
467 of the ortp receiver.
468 - improved audio grabbing. The 'grab' command of para_audiod
469 has its own set of command line options. Read the output of
470 "para_audioc help grab" for more info.
471 - oggdec: configurable input prebuffer size.
472 - the new error subsystem gives better error diagnostics
473 and reduces code size.
474
475
476 -----------------------------------------
477 0.2.8 (2006-01-02) "dynamic accumulation"
478 -----------------------------------------
479
480 The new modular filter design and the para_play-hangs bugfix.
481
482 - new executable: para_filter. It combines para_mp3dec,
483 para_oggdec and para_compress. It also adds a further filter
484 type, wav, that just inserts a wave header at the desired point
485 of the filter chain. All 'piping' is done in-memory (i.e. no
486 read/write operations are used).
487 - para_play: fix a stupid bug that caused it to hang under
488 certain circumstances.
489
490
491 -------------------------------------------
492 0.2.7 (2006-12-27) "transparent invariance"
493 -------------------------------------------
494
495 Not many user-visible changes but a fair amount of internal improvements.
496
497
498 - The http sender buffers data if it can not be sent
499 out immediately (because the socket is not writable). This
500 should prevent para_server from shutting down the connection
501 too early on a loaded network.
502 - para_play also prebuffers data if it is told to start at a
503 future time by the --start_time option.
504 - The return of para_recv: It combines para_ortp_recv and
505 para_http_recv. Use the --receiver option to switch between
506 the two. para_recv builds without libortp, but contains
507 only the http receiver in this case.
508 - update to ortp 0.8.1. As this ortp release contains incompatible
509 changes, para_recv-0.2.7 won't link against older ortp libs.
510 - improved ortp timings.
511 - use of gcc-extensions that #define away for non-gcc and
512 gcc < 3.0.
513
514
515 -------------------------------------------
516 0.2.6 (2005-10-29) "recursive compensation"
517 -------------------------------------------
518
519 Transparent session encryption (uses openssl's Alleged RC4 cipher),
520 the internal find command and several other improvements and cleanups.
521
522 - Encrypt the session if encryption is requested by the client
523 (default for para_client 0.2.6). This is backwards
524 compatible, so older clients can still connect to para_server
525 0.2.6. Use the new client option --plain to request an
526 uncrypted session (off by default, must be set to on in
527 order to connect to para_server 0.2.x with 0 <= x <= 5).
528 - para_server uses an internal function to locate audio files
529 rather than calling find(1). The server option
530 --mysql_audio_file_dir replaces --mysql_find_cmd.
531 - documentation update
532 - man pages
533 - header file cleanup
534 - para_client code cleanup
535 - para_gui: faster display of output of display commands
536
537
538 ------------------------------------------
539 0.2.5 (2005-10-13) "aggressive resolution"
540 ------------------------------------------
541
542 This release adds internal senders, i.e. no more external programs are
543 spawned for sending out the audio data. There are two different senders
544 available: The http sender and the ortp sender (former para_send which
545 is no longer needed).
546
547 The new sender code has a plugin-like design so it can be easily
548 extended should there be be any future need for supporting another
549 network streaming protocol. All senders are completely independent of
550 each other. In particular, the http and the ortp sender can operate
551 in parallel.
552
553 - new server command: sender to control senders at runtime.
554 Read the output of "para_server -h" and "para_client help
555 sender" for more information.
556 - para_recv renamed to para_ortp_recv
557 - new executable: para_http_recv, a simple command line
558 http receiver.
559 - major afs/mp3/ogg code simplifications due to internal
560 senders.
561 - ogg timing improvements
562 - fix several minor memory leaks (found by valgrind)
563 - empty stream definitions work again
564 - com_ne(): ignore errors on remove
565 - audiod: fix segfault on server restart
566
567
568 ---------------------------------------
569 0.2.4 (2005-09-21) "toxic anticipation"
570 ---------------------------------------
571
572 Several small improvements, fixes and the new grab command.
573
574 - audiod:
575 - new command: "grab" to grab the output of the stream reader
576 or any filters. Read the output of "para_audioc help grab"
577 for more information.
578 - fix memory leak
579 - code cleanup
580 - audioc: new command line option: --bufsize to specify a
581 buffer size different from the default size 8192.
582 - improved error diagnostics for para_play.
583 - new configure option: --enable-ssldir so search for openssl in
584 non-standard places
585 - sdl_gui: Make it look nice again for 1024x768
586 - server: report total size of memory allocated with sbrk by malloc,
587 new command line option: --announce_time
588
589
590 -----------------------------------------
591 0.2.3 (2005-09-01) "hydrophilic movement"
592 -----------------------------------------
593
594 Two new executables and major feature enhancements.
595
596 - audiod filters: It is now possible to specify arbitrary many
597 (including none) filters for each supported audio
598 format. This can be used e.g. for normalizing volume,
599 transforming or grabbing the audio stream, or for using
600 visualizers. Read the output of "para_audiod -h" for the
601 syntax of the new --filter_cmd option.
602 - new executable: para_play, a tiny alsa player. It
603 can play wave files or raw pcm (16 bit little endian)
604 from stdin.
605 - new executable: para_compress, a dynamic range compressor
606 intended to keep audio output at a consistent volume. Derived
607 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
608 - audiod: New option: --stream_delay. This can be used in
609 a local network to syncronize the audio output of all
610 clients that play the same stream.
611
612
613 ------------------------------------------
614 0.2.2 (2005-08-19) "tangential excitation"
615 ------------------------------------------
616
617 Mostly internal changes in this release, but also some new commands
618 for the mysql database tool.
619
620 - cleanup exec.c, fix para_exec bug
621 - compile time loglevel (log messages below the given level
622 won't be compiled in, which reduces the size of the
623 resulting binaries)
624 - new log macros that shorten the size of the source code.
625 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
626 to send only zeros. With this workaround, para_audioc works
627 again.
628 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
629 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
630 (new entry), "snp" (set numplayed). Read the manual for more
631 information.
632
633
634 ---------------------------------------
635 0.2.1 (2005-08-15) "surreal experience"
636 ---------------------------------------
637
638 Here comes paraslash-0.2.1. It contains a couple of new features and,
639 surprise, only minor bug fixes.
640
641 - kill noisy mp3 debug message
642 - cleanup of the build system
643 - para_server and para_client directly use the crypto routines
644 of the openssl library rather than invoking the openssl command
645 line utitlity
646 - server/audiod: new option --user to switch to the given user
647 when invoked as root. Read the output of "para_server -h" for
648 more information.
649 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
650 status. Default: "para_audioc stat"
651 - sdl_gui: new option --pic_cmd to be used to download the picture.
652 Default: "para_client pic"
653 - audiod: 5 slots ought to be enough for everybody
654 - audiod: new status item: Uptime, kill hup command
655
656
657
658 ------------------------------------------
659 0.2.0 (2005-08-06) "distributed diffusion"
660 ------------------------------------------
661
662 After several month of increased development activity, paraslash-0.2.0
663 has arrived. It contains many new features and is much more
664 self-contained than the old 0.1.x series. Enjoy!
665
666
667 - para_server: fix hang on song change and crash on sighup.
668 Speed up mysql queries. The DIR_LIKE macro is gone.
669 - new executables: para_audiod, the local audio daemon that
670 starts playback (uses SCM_CREDENTIALS socket magic) and
671 para_audioc, the corresponding client.
672 - new executables: para_mp3dec/para_oggdec, two really teensy
673 decoders. para_mp3dec is based on libmad, para_oggdec requires
674 libvorbisfile.
675 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
676 they are now called para_send and para_recv respectively.
677 - documentation updates
678 - para_gui is themable. For now there is the default theme that
679 looks as before and the simple theme: blue and easy.
680 - gui: audio streaming is now handled by audiod. Time display shows
681 playback time rather than streaming time
682 - slider: update to libzmw-0.2.0
683 - para_krell: fix crash on server shutdown
684 - switch from gzip to bzip2
685
686
687 ----------------------------------------
688 0.1.7 (2005-04-18) "melting penetration"
689 ----------------------------------------
690
691 The main change in this release is clearly the oggvorbis rewrite,
692 but there are also lots of smaller changes. If you intend to use both
693 the mp3 and the ogg plugin, it is recommended to use software mixing,
694 e.g. the dmix plugin which is provided by ALSA.
695
696 - new executables: para_ovsend and para_ovrecv for sending/receiving
697 oggvorbis files via rtp. Requires the open rtp library. Get it at
698 http://www.linphone.org/ortp/
699 - rewrite of the ogg_vorbis core code
700 - configure detects libzmw and, if detected, includes
701 para_slider to the list of binaries to be built by make
702 - server stream writers read from their associated fifo rather
703 than from stdin
704 - slider: two new sliders, lastplayed and numplayed
705 - fix nasty double free bug which caused random segfaults in case of
706 mp3 files with invalid header information
707 - gui: new command line option: --stream_timeout=seconds to
708 deactivate a slot if it is idle for that many seconds (default=`5')
709 - diffstats
710
711
712 ---------------------------------------
713 0.1.6 (2005-03-05) "asymptotic balance"
714 ---------------------------------------
715
716 Only little user-visible changes in this release. Mainly bugfixes and
717 core code cleanup. This is probably the most stable version ever if you
718 stick to mp3...
719
720 - fix several memory leaks
721 - rename default name of mysql database from "music" to "paraslash".
722 Use para_server's --mysql_database option if you do not want to
723 rename your old database.
724 - rework ogg vorbis code
725 - make update command work on mysql servers with LOCAL_INFILE
726 disabled
727 - gui: improved stream I/O (slots)
728 - simplified audio format API
729 - para_pob_ogg is gone
730
731 ------------------------------------
732 0.1.5 (2004-12-31) "opaque eternity"
733 ------------------------------------
734
735 Let's slide gently into the new year.
736
737 - new: para_slider (not built automatically, type "make
738 para_slider" to build). A toy for those who always felt that
739 creating stream definitions is difficult. See screenshots,
740 README and FEATURES for more info.
741 - improved signal handling. Fixes server segfault on SIGHUP
742 for linux kernels newer than Aug 24 2004 and makes para_gui
743 race-free.
744 - reload database tool on SIGHUP
745 - improved help message for sl
746 - do not log "broken pipe" messages as errors. They are
747 perfectly ok.
748 - fix wrong error message on permission errors
749
750 -----------------------------------------
751 0.1.4 (2004-12-19) "tunneling transition"
752 -----------------------------------------
753
754 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
755 Hopefully, most of them got wiped out with this release. Some
756 enhancements went also in.
757
758 - improved error diagnostics for all commands
759 - stradd/picadd: overwrite previous contents if entry already
760 exists, rather than returning errors
761 - stradd: use current stream if invoked without args
762 - faster (and hopefully more stable) ogg-vorbis handling
763 - para_krell: reap children to avoid zombie-flooding in case
764 no server is running
765 - si: report also server pid
766 - server: don't busy-loop if dbtool reports only invalid files.
767 - gui: CTRL+C works again, fix stream_read command line option
768 - fix pic_add, hist
769 - fix mysql dbtool startup in case no database exists
770 - many small fixes and cleanups
771
772 ---------------------------------------
773 0.1.3: (2004-12-10) "vanishing inertia"
774 ---------------------------------------
775
776 Starting from this release, the database tools are integrated in the
777 server binary. This decreases server startup time, reduces code size
778 and speeds up database commands. However, the layout of the underlying
779 mysql database changed only slightly and 0.1.3 should be backwards
780 compatible in that respect.
781
782 Visible changes:
783
784 - If mysql is not detected at compile time, or fails to init
785 at runtime, fall back to the dopey database tool which should
786 always work.
787 - para_dbtool and dbtool.conf are gone. All mysql specific
788 options are read from server.conf and are prefixed by 'mysql_'.
789 - new command: cdt (change database tool)
790 - new command line option: dbtool (choose startup database tool)
791 - The name of current stream is now stored in the database,
792 so paraslash remembers its current stream when restarted.
793 - new command: csp (change stream and play)
794 - para_gui also reports current database tool and server uptime
795
796
797 -------------------------------------------
798 0.1.2: (2004-11-28) "spherical fluctuation"
799 -------------------------------------------
800
801 Point release before the big dbtool changes go in.
802
803 - dbtool: rename ca to cam (copy all meta data). It now also
804 copies numplayed and lastplayed time as well as the picture
805 id.
806 - fix endless-loop-bug caused by mp3 files with invalid header
807
808 -----------------------------------------
809 0.1.1: (2004-11-05) "floating atmosphere"
810 -----------------------------------------
811
812 - gkrellm plugin
813 - new dbtool command: mbox. Browse your sound-file collection
814 with your favorite mail reader.
815 - several small fixes
816
817 -------------------------------------
818 0.1.0: (2204-10-22) "rotating cortex"
819 -------------------------------------
820
821 - fix logging bug for loglevel > VERBOSE
822 - fix skip command
823 - correct timings for vbr mp3s
824 - modular audio format support
825 - ogg-vorbis support (experimental)
826 - new server option: autoplay
827
828 -----------------------------------------
829 0.0.99: (2004-07-25) "harmonic deviation"
830 -----------------------------------------
831
832 - rename projectname from icc to paraslash (play, archive, rate
833 and stream large audio sets happily)
834 - paraslash is no longer restricted to one particular audio
835 streaming software
836 - new dbtool commands (stradd, strq, strdel) for easy stream
837 managment w/o configuration file. That obsoletes stream_defs
838 file/config option for dbtool.
839 - picadd accepts jpeg data from stdin
840 - new server commands: ps (select previous stream), sc (song change)
841 - new default pictures for sdl_gui
842 - gui: new key_map option for binding commands and internal
843 functions to arbitrary keys, nice help screen, rip out
844 soundcard/linux specific stuff, avoid noise artefacts while jumping,
845 show silly logo on startup
846 - new executables: para_fade for fading volume, para_dbadm for
847 manipulating attributes
848 - cdb adds _all_ tables to mysql database
849 - revised and beautified documentation
850 - sample dbtool rewritten in C
851 - autoconf
852
853 ---------------------------------------------
854 0.0.98: (2003-12-26) "incremental smoothness"
855 ---------------------------------------------
856
857 - kick icecast in favour of poc. That removes some races and reduces
858 core code considerably.
859 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
860 give finer info on afs' status.
861 - gui can start decoder (see config options). Further new gui
862 commands: refresh (^L), jmp (F1-F10)
863 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
864 terminates gui. This fixes dead instances consuming memory
865 continuously.
866 - new dbtool command: verb for sending verbatim sql queries.
867 - fix pid_list races (by removing pid_list)
868 - codename funnies
869
870 --------------------
871 0.0.97: (2003-10-26)
872 --------------------
873
874 - installation prefix now defaults to /usr/local
875 - new commands for gui: snozze, sleep and reread config
876 - config file for gui and sdl_gui
877 - fix problems with filenames containing funny characters
878 (reported by Thomas Forell)
879 - improved signal handling for gui, now it rereads conf on SIGHUP
880 - new dbtool command: cdb (create database)
881 - switch from argtable to gengetopt
882 - major code cleanup and speed improvements
883 - fix several potential buffer overflows
