[paraslash.git] / NEWS
1 -------------------------------------------
2 0.4.7 (to be announced) "infinite rollback"
3 -------------------------------------------
4
5 The new ao writer, support for ssh RSA keys and a couple of other
6 enhancements.
7
8 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
9 platforms through the libao audio library.
10 - Support for RSA keys generated with ssh-keygen.
11 - configure: improved options for ogg/vorbis/speex.
12 - The git version reported by --version always matches HEAD.
13 - The autogen script detects the number of processors and
14 runs a parallel make if possible.
15 - Major cleanup of the crypto API.
16 - Documentation updates.
17
18 ------------------------------------------
19 0.4.6 (2011-03-31) "deterministic entropy"
20 ------------------------------------------
21
22 Lots of ogg/vorbis improvements, the new test suite, enhancements
23 for para_gui and a fair amount of other bug fixes.
24
25 - For DCCP/OGG streams the audio file header is only sent once
26 at the beginning of the stream rather than periodically
27 every five seconds. This reduces network traffic and the
28 FEC group size.
29 - The vorbis comment header is replaced by an empty dummy header
30 before the header is sent over the network. This also results in
31 less network traffic and smaller FEC groups.
32 - The new "test" make target allows to perform some sanity checks prior
33 to installing the package.
34 - ogg timing fixes and performance improvements
35 - Scheduler improvements
36 - Proper exit codes for para_write
37 - para_gui: New option --theme to select a startup theme. Several
38 other improvements and fixes.
39 - aacdec error message cleanups
40 - simplified color error handling
41
42 --------------------------------------------
43 0.4.5 (2010-12-17) "symmetric randomization"
44 --------------------------------------------
45
46 Bug fixes, internal cleanups and variable-sized FEC slices.
47
48 - Contains a fix for an invalid-free-bug in the ogg audio format
49 handler code.
50 - Switching off the DCCP sender works again.
51 - para_audiod handles crashes of para_server more robustly.
52 - Internal scheduler and writer cleanups.
53 - Reduced latency due to variable-sized FEC slices.
54 - Improved documentation and error diagnostics.
55 - The build of para_server is now optional, allowing the build
56 to succeed in case libosl is not installed.
57
58 ------------------------------------------
59 0.4.4 (2010-08-06) "persistent regularity"
60 ------------------------------------------
61
62 Support for yet another audio format, para_write improvements and
63 bug fixes.
64
65 - Support for the speex codec.
66 - Support for sample formats other than 16 bit little endian.
67 - error2.h is now created by a perl script which speeds up configure
68 considerably.
69 - Fix a bug in the aac decoder which could lead to segfaults in
70 para_filter/para_audiod.
71 - Fixes for autoconf-2.66.
72
73 ----------------------------------------
74 0.4.3 (2010-07-05) "imaginary radiation"
75 ----------------------------------------
76
77 Many improvements for the DCCP and the UDP transport, the new user
78 manual and the usual mix of bug fixes and internal improvements.
79
80 - FEC support for the DCCP sender (Gerrit Renker). The new
81 --dccp_max_slice_size, --dccp_data_slices_per_group and
82 --dccp_slices_per_group options can be used to set the FEC
83 parameters for the DCCP transport.
84 - DNS lookups for UDP targets (Gerrit Renker).
85 - The new user manual replaces the README, README.afs, REQUIREMENTS
86 and INSTALL documents.
87 - Fix an end-of-file detection bug in the oggdec filter.
88 - The new nonblock API.
89 - Both options of the oggdec filter have been removed.
90 - New debug mode for the internal scheduler.
91
92 ------------------------------------------
93 0.4.2 (2010-04-23) "associative expansion"
94 ------------------------------------------
95
96 It's been some time since the last release, but finally here is
97 paraslash-0.4.2. The bulk of the changes comes from the new buffer
98 tree API, but there are changes all over the tree. Mainly performance
99 and usability improvements, but also quite some bug fixes.
100
101 - The new buffer tree API.
102 - DCCP: Support for CCID negotiation (Gerrit Renker).
103 - UDP robustness fixes.
104 - The --bufsize option for mp3dec is gone as it no longer makes sense
105 for the new buffer tree API.
106 - Fix audible buffer underruns for wma streams.
107 - The alsa writer no longer prints meaningless underrun durations.
108 - audiod: Defaults work also for udp streams. If no filter is
109 given for an audio format that is received via upd, fecdec is
110 automatically added as the first filter (along with the decoder).
111
112 ---------------------------------------
113 0.4.1 (2009-12-22) "concurrent horizon"
114 ---------------------------------------
115
116 Support for another audio format, minor feature enhancements and lots of bug
117 fixes. All fixes that have been accumulated in the maint branch (in particular
118 those mentionened in the 0.3.6 release notes) appear in this release as well.
119
120 - wma support.
121 - new afh option: --human to activate human-readable output.
122 - new server/audiod option: --log-timing to print timing information.
123 - build system improvements.
124 - source code documentation updates.
125
126 -------------------------------------
127 0.3.6 (2009-12-07) "cubic continuity"
128 -------------------------------------
129
130 Quite a few bugs have been found and fixed since 0.3.5, so here's
131 another 0.3.x release. No new features.
132
133 - Always check return value of malloc().
134 - ogg vorbis/FEC: Do not write garbage after the audio file header.
135 - exit if root privileges could not be dropped.
136 - FEC: Fix computation of extra slices.
137 - oss: Fix check for empty input buffer.
138 - Avoid buffer underruns due to filter chain output buffer constraints.
139 - server: Fix assignment of afs_pid.
140 - Don't panic if the afs database contains unknown audio formats.
141 - http/dccp: Do not send the audio file header twice.
142 - FEC: Timing improvements.
143
144 ----------------------------------------------
145 0.4.0 (2009-11-10) "simultaneous independence"
146 ----------------------------------------------
147
148 Two significant changes which require the new version number: The
149 improved authentication dialog and the fact that the database code
150 has been moved to a library, libosl. To use the new version, you have
151 to generate new RSA keys, see INSTALL for details. A shell script is
152 provided for conversion of the 0.3 database to the new 0.4 format.
153
154 - stronger crypto for client authentication
155 - the database code has been moved to a library
156 - improved status item handling
157 - cleanup of the build system
158 - The "-V" option now also prints the git version
159 - the new parser-friendly listing mode for the ls and stat commands
160 - mandatory rc4 encryption
161 - major audio format handler cleanups
162 - (id3,...) tags are no longer stored as a combined string in the database
163 - new mood methods: artist_matches, title_matches, comment_matches,
164 album_matches, year_maches, year.
165
166 --------------------------------------------
167 0.3.5 (2009-09-21) "symplectic separability"
168 --------------------------------------------
169
170 Full client support for *BSD Unixes, complete re-write of the ogg
171 vorbis audio format handler, various improvements all over the place
172 and the usual mix of bugfixes. This release marks the end of the 0.3
173 series if no serious problems show up.
174
175 - the new oss writer (supported on *BSD and Linux)
176 - rewrite of the ogg vorbis audio format handler. It's
177 recommended to replace the chunk tables of existing ogg
178 vorbis files in the afs database by re-adding these files
179 with "add -f".
180 - support for netmask subsets (Gerrit Renker)
181 - the new prebuffer filter
182 - improved signal handling
183 - variable fec output buffer size
184 - improved FEC timing fixes audible buffer underruns in UDP mode
185 - --log_color actually works
186 - new ls option: -d (print dates as seconds after the epoch)
187 - update to gengetopt 2.22.2
188 - support for RSA keys of size > 512 bits
189 - new option "mixer_channel" for para_fade
190
191 -----------------------------------------
192 0.3.4 (2009-05-07) "elliptic inheritance"
193 -----------------------------------------
194
195 The new udp sender, forward error correction, colored logs and various
196 other improvements. As the udp sender does not depend on any special
197 libraries, it is built unconditionally.
198
199 - The udp sender replaces the ortp sender. The new code uses forward
200 error correction to protect against packet losses. Many thanks to
201 Gerrit Renker for providing ipv6 support.
202 - The default port for udp streaming now defaults to 8000, like
203 for the http and the dccp senders/receivers.
204 - Loglevels are now specified as symbolic names, e.g.
205 "--loglevel info".
206 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
207 - para_server/para_audiod: Color support for log messages.
208 - new options for mp3dec: --ignore-crc, --bufsize
209 - new audiod option: --config-file.
210 - gengetopt cleanups.
211 - Improved help/man pages: The documentation of para_audiod,
212 para_recv, para_filter and para_write now also contains
213 all options of the available receivers/filters/writers. The
214 man page of para_fade contains a description of the different
215 modes of operation.
216 - More source code documentation.
217 - vss timing fixes.
218
219 --------------------------------------------
220 0.3.3 (2008-12-01) "axiomatic perspectivity"
221 --------------------------------------------
222
223 Internal code cleanups, bug fixes, improved tag handling and the new
224 amplification filter.
225
226 - para_server uses the generic scheduling code.
227 - overhaul of the virtual streaming system.
228 - mp3: id3 version 2 support via libid3tag (optional)
229 - ogg: vorbis comment support.
230 - aac meta info support.
231 - mp3 audio format handler cleanups.
232 - new filter: "amp" to amplify the amplitude of the audio stream
233 - new status item/database entry: amplification. It is
234 used by the amp filter to pre-amplify the audio stream.
235 - fix a close-without-open bug in para_write.
236 - fix a bug in com_init() which was introduced in 0.3.2.
237 - better error diagnostics for para_client.
238
239 -----------------------------------------
240 0.3.2 (2008-04-11) "probabilistic parity"
241 -----------------------------------------
242
243 The new para_afh executable, scheduling and documentation improvements.
244
245 - new ls option: -lc (list chunk table)
246 - new executable: para_afh, the stand-alone audio file handler tool
247 - afs commands can send output more than SHMMAX (32MB on Linux). This
248 also reduces the memory usage of commands that produce large amounts
249 of output.
250 - major scheduler and audiod cleanups.
251 - more detailed and much nicer man pages.
252
253 ---------------------------------------
254 0.3.1 (2008-02-23) "liquid interaction"
255 ---------------------------------------
256
257 A mix of cleanups, bug fixes, improvements, and some new features. No
258 significant changes to the new database (osl) code, which is generally
259 a good sign.
260
261 - Share some similar/duplicate code between the http and the
262 dccp sender.
263 - Generic access control lists for paraslash senders.
264 - dccp sender: Access control lists, connection limiting and support
265 for the allow,deny,on,off,help sender commands.
266 - The default dccp port changed from 5001 to 8000 (suggested by
267 Gerrit Renker).
268 - para_server starts even if not all public keys could be loaded.
269 - Audiod performance improvements.
270 - fix a bug in the "off" command of the http sender.
271 - fix some fd and memory leaks.
272 - Update to gengetopt-2.22.
273
274 -------------------------------------
275 0.3.0 (2008-01-12) "solar saturation"
276 -------------------------------------
277
278 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
279
280
281 Usually one might expect lots of new features AND a big increase in size
282 for a major release like this.
283
284 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
285 ever. The decrease in size is mostly due to the removal of some
286 graphical tools (which were only quick hacks anyway). But also the
287 fact that the mysql code is gone cuts down the size a bit.
288
289 Being independent of mysql comes at a cost: The fact that paraslash
290 now contains its own database (the object storage layer, osl) increases
291 the (stripped) binary size of para_server by ~50K on i386.
292
293 - no more restrictions on unique basenames.
294 - independent of mysql: The new self-contained object
295 storage layer (osl) replaces the mysql database.
296 - New executable para_fsck: Check integrity of osl tables.
297 - Lyrics support.
298 - Reliable audio file move/rename detection.
299 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
300 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
301 Solaris (sparc64).
302 - the new osl-based audio file selector (afs) replaces the random,
303 the playlist and the mysql selector of paraslash-0.2.x.
304 - IPv6 support (thanks to Gerrit Renker).
305 - paraslash-0.2.x streams are now called "moods". Writing
306 0.3.x-mood definitions should be both easier and more
307 powerful than writing 0.2.x-stream definitions.
308 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
309 been removed. The world is a better place without them. However,
310 para_gui is still there.
311 - afs tracks audio file selection also in playlist mode.
312 - few easy-to-use afs commands replace the many not-so-easy-to-use
313 mysql commands (and are available also in playlist mode).
314 - Improved error subsystem.
315 - The earth-shaking new logo.
316
317 -----------------------------------------
318 0.2.17 (2007-11-20) "isotropic threshold"
319 -----------------------------------------
320
321 Mainly bugfixes and cleanups in this version which marks the end of
322 the 0.2.x series if no serious bugs show up after the release.
323
324 - mysql_selector: fix a locking bug.
325 - universal chunk queueing.
326 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
327 to Gerrit Renker).
328 - be more carful wrt. signed vs. unsigned argument passing.
329 - cleanup error.h and fix some references to invalid error
330 codes.
331 - update to gengetopt-2.21.
332 - update to ortp-0.13.1.
333 - autoconf: extend checks for headers, library functions and
334 compiler characteristics.
335 - Fix streaming of large mp3 files.
336 - Fix an off-by-one bug in playlist handling.
337
338 --------------------------------------
339 0.2.16 (2007-04-05) "neural discharge"
340 --------------------------------------
341
342 The main change in this release is the major audio format handler
343 cleanup which removes some similar/duplicate code and makes it easier
344 to implement plugins for other audio formats. Of course, the usual mix
345 of other improvements/changes/bugfixes also made it into the release.
346
347 - simplified audio format handlers (most of the handling functions
348 were moved one layer up to the virtual streaming system).
349 - para_server uses mmap to read audio files
350 - repositioning of mp3 streams is much faster, in particular for
351 jumping near the end of large mp3 files.
352 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
353 and AFS_WRITE.
354 - fix a bug in para_filter that caused decoding of aac files
355 to start only after a few seconds.
356 - fix osx_writer hangs
357 - simplified dccp code (thanks to Gerrit Renker)
358 - the compress filter works also on big endian systems (ppc)
359
360 -----------------------------------------
361 0.2.15 (2007-02-16) "inductive resonance"
362 -----------------------------------------
363
364 Minor improvements, more documentation and a bunch of bug fixes.
365
366 - para_server: The server.users file is only read once on server
367 startup rather than for each connection
368 - mp3dec: Fix decoding of corrupt mp3 files
369 - afs (audio file sender) is now called vss (virtual streaming
370 system). Consequently, the permission flags specified in
371 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
372 become VSS_READ and VSS_WRITE respectively.
373 - para_audiod/para_filter: Fix a bug that caused the last chunk
374 of audio data not being written under certain circumstances
375 - audiod: compute the difference of server time and local time
376 correctly
377 - para_server/para_audiod: Fix some memory leaks
378 - documentation improvements
379 - configure.ac: fix checks for para_krell
380 - new man pages
381
382 -------------------------------------------
383 0.2.14 (2006-10-15) "transient singularity"
384 -------------------------------------------
385
386 The only major enhancement of this version is the osx writer which completes
387 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
388 until now for reasons beyond the scope of this changelog entry.
389
390 - new output plugin for Mac Os: the osx writer
391 - rename configure command line options from --enable-xxx-headers to
392 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
393 - configure: new command line options: --with-mad-headers,
394 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
395 - some robustness fixes
396 - dymamic audio format recognition for audiod
397 - para_server: new command line option: --autoplay_delay
398 - para_audiod: new command line option: --clock_diff_count
399
400 ---------------------------------------
401 0.2.13 (2006-07-14) "sonic convolution"
402 ---------------------------------------
403
404 A bunch of new features and core changes.
405
406 - the new paraslash scheduler, short and sweet.
407 - Support for m4a/mp4 files via the new aac audio format
408 handler/filter (requires libfaad).
409 - each writer has its own command line parser, just like
410 para_recv and para_filter.
411 - para_client and para_audioc use the error subsystem
412 - writers are integrated in para_audiod (currently linux-only)
413 - para_client is integrated in para_audiod
414 - random/playlist selector: improved info strings
415 - new audiod commands: tasks, kill
416 - update to libortp-0.10.1
417 - para_fade: wake time defaults to 8 hours from now
418 - update to autoconf-2.60
419
420
421 ------------------------------------------
422 0.2.12 (2006-05-12) "oriented abstraction"
423 ------------------------------------------
424
425 Many user-visible changes in this release and lots of new
426 features:
427
428
429 - the new optional dccp sender/receiver. It uses the datagram
430 congestion control protocol. You'll need a fairly new kernel
431 for this.
432 - paraslash works on Mac OS X (thanks to Gerd Becker)
433 - para_play renamed to para_write
434 - modular output plugin design (writers) for para_write
435 - new file_writer output plugin for para_write
436 - compress filter speed improvements
437 - update to libortp-0.9.1
438 - update to gengetopt-2.17rc
439 - para_client no longer depends on libreadline (as the
440 code for the interactive mode was removed).
441 - gcc-2-95 is no longer a supported compiler. It may still
442 work, but it gets no more testing.
443 - the tarball no longer contains the screenshot images which
444 reduces its size quite a bit.
445 - configure: new command line options: --enable-mysql-headers
446 and --enable-mysql-libs
447
448 ------------------------------------
449 0.2.11 (2006-03-11) "atomic duality"
450 ------------------------------------
451
452 Here it is, the first paraslash release developed with git. There
453 are fairly many user-visible changes in this release. As two out of
454 the three "database tools" of paraslash don't use a database at all,
455 they are now called "audio file selectors" instead.
456
457
458 - the cdt command (change database tool) becomes chs (change
459 selector)
460 - no more colon separators: The syntax of some options of
461 para_audiod and para_filter have changed. Use --help for
462 more info (and some examples).
463 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
464 - switch from cvs to git (should've done that earlier)
465 - the new ipc subsystem
466 - new audio file selector: playlist
467 - para_server: the dopey selector is now called "random",
468 and is the default selector. Use the --selector option to
469 choose another selector at startup, or the chs command to
470 change the selector at runtime.
471 - X86_64 fixes (thanks to Steffen Klassert)
472 - para_play fixes
473
474
475 --------------------------------------
476 0.2.10 (2006-02-17) "cyclic attractor"
477 --------------------------------------
478
479 Huge documentation update, a scrollable window for para_gui, ortp
480 improvements, and of course many small fixes not mentioned here.
481 The diffstat below is rather misleading as most insertions are due
482 to the new source documentation.
483
484 - autoconf cleanup
485 - para_server also uses the new error subsystem
486 - lots of new documentation (UTSL)
487 - gui improvements:
488 - keysyms for cursor keys and for next/previous page keys
489 - scrollable output window
490 - new internal commands: scroll up/down, page up/down
491 - fix color of command output.
492 - ortp: the --chunk_time and --header flags are no longer needed
493 for para_recv/para_audiod as this information is now encoded in
494 each rtp packet sent by para_server.
495
496
497 -------------------------------------------
498 0.2.9 (2006-01-24) "progressive turbulence"
499 -------------------------------------------
500
501 Internal audiod receivers/filters, the new error subsystem and
502 a lot of small improvements.
503
504 - para_recv and para_filter are integrated into the para_audiod
505 binary, i.e. audiod no longer spawns a new process for
506 each receiver/filter. As para_recv and para_filter might be
507 useful as standalone programs, they still get built (linked
508 against the same object files that are also used for audiod).
509 - further ortp timing improvements should reduce the CPU usage
510 of the ortp receiver.
511 - improved audio grabbing. The 'grab' command of para_audiod
512 has its own set of command line options. Read the output of
513 "para_audioc help grab" for more info.
514 - oggdec: configurable input prebuffer size.
515 - the new error subsystem gives better error diagnostics
516 and reduces code size.
517
518
519 -----------------------------------------
520 0.2.8 (2006-01-02) "dynamic accumulation"
521 -----------------------------------------
522
523 The new modular filter design and the para_play-hangs bugfix.
524
525 - new executable: para_filter. It combines para_mp3dec,
526 para_oggdec and para_compress. It also adds a further filter
527 type, wav, that just inserts a wave header at the desired point
528 of the filter chain. All 'piping' is done in-memory (i.e. no
529 read/write operations are used).
530 - para_play: fix a stupid bug that caused it to hang under
531 certain circumstances.
532
533
534 -------------------------------------------
535 0.2.7 (2006-12-27) "transparent invariance"
536 -------------------------------------------
537
538 Not many user-visible changes but a fair amount of internal improvements.
539
540
541 - The http sender buffers data if it can not be sent
542 out immediately (because the socket is not writable). This
543 should prevent para_server from shutting down the connection
544 too early on a loaded network.
545 - para_play also prebuffers data if it is told to start at a
546 future time by the --start_time option.
547 - The return of para_recv: It combines para_ortp_recv and
548 para_http_recv. Use the --receiver option to switch between
549 the two. para_recv builds without libortp, but contains
550 only the http receiver in this case.
551 - update to ortp 0.8.1. As this ortp release contains incompatible
552 changes, para_recv-0.2.7 won't link against older ortp libs.
553 - improved ortp timings.
554 - use of gcc-extensions that #define away for non-gcc and
555 gcc < 3.0.
556
557
558 -------------------------------------------
559 0.2.6 (2005-10-29) "recursive compensation"
560 -------------------------------------------
561
562 Transparent session encryption (uses openssl's Alleged RC4 cipher),
563 the internal find command and several other improvements and cleanups.
564
565 - Encrypt the session if encryption is requested by the client
566 (default for para_client 0.2.6). This is backwards
567 compatible, so older clients can still connect to para_server
568 0.2.6. Use the new client option --plain to request an
569 uncrypted session (off by default, must be set to on in
570 order to connect to para_server 0.2.x with 0 <= x <= 5).
571 - para_server uses an internal function to locate audio files
572 rather than calling find(1). The server option
573 --mysql_audio_file_dir replaces --mysql_find_cmd.
574 - documentation update
575 - man pages
576 - header file cleanup
577 - para_client code cleanup
578 - para_gui: faster display of output of display commands
579
580
581 ------------------------------------------
582 0.2.5 (2005-10-13) "aggressive resolution"
583 ------------------------------------------
584
585 This release adds internal senders, i.e. no more external programs are
586 spawned for sending out the audio data. There are two different senders
587 available: The http sender and the ortp sender (former para_send which
588 is no longer needed).
589
590 The new sender code has a plugin-like design so it can be easily
591 extended should there be be any future need for supporting another
592 network streaming protocol. All senders are completely independent of
593 each other. In particular, the http and the ortp sender can operate
594 in parallel.
595
596 - new server command: sender to control senders at runtime.
597 Read the output of "para_server -h" and "para_client help
598 sender" for more information.
599 - para_recv renamed to para_ortp_recv
600 - new executable: para_http_recv, a simple command line
601 http receiver.
602 - major afs/mp3/ogg code simplifications due to internal
603 senders.
604 - ogg timing improvements
605 - fix several minor memory leaks (found by valgrind)
606 - empty stream definitions work again
607 - com_ne(): ignore errors on remove
608 - audiod: fix segfault on server restart
609
610
611 ---------------------------------------
612 0.2.4 (2005-09-21) "toxic anticipation"
613 ---------------------------------------
614
615 Several small improvements, fixes and the new grab command.
616
617 - audiod:
618 - new command: "grab" to grab the output of the stream reader
619 or any filters. Read the output of "para_audioc help grab"
620 for more information.
621 - fix memory leak
622 - code cleanup
623 - audioc: new command line option: --bufsize to specify a
624 buffer size different from the default size 8192.
625 - improved error diagnostics for para_play.
626 - new configure option: --enable-ssldir so search for openssl in
627 non-standard places
628 - sdl_gui: Make it look nice again for 1024x768
629 - server: report total size of memory allocated with sbrk by malloc,
630 new command line option: --announce_time
631
632
633 -----------------------------------------
634 0.2.3 (2005-09-01) "hydrophilic movement"
635 -----------------------------------------
636
637 Two new executables and major feature enhancements.
638
639 - audiod filters: It is now possible to specify arbitrary many
640 (including none) filters for each supported audio
641 format. This can be used e.g. for normalizing volume,
642 transforming or grabbing the audio stream, or for using
643 visualizers. Read the output of "para_audiod -h" for the
644 syntax of the new --filter_cmd option.
645 - new executable: para_play, a tiny alsa player. It
646 can play wave files or raw pcm (16 bit little endian)
647 from stdin.
648 - new executable: para_compress, a dynamic range compressor
649 intended to keep audio output at a consistent volume. Derived
650 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
651 - audiod: New option: --stream_delay. This can be used in
652 a local network to syncronize the audio output of all
653 clients that play the same stream.
654
655
656 ------------------------------------------
657 0.2.2 (2005-08-19) "tangential excitation"
658 ------------------------------------------
659
660 Mostly internal changes in this release, but also some new commands
661 for the mysql database tool.
662
663 - cleanup exec.c, fix para_exec bug
664 - compile time loglevel (log messages below the given level
665 won't be compiled in, which reduces the size of the
666 resulting binaries)
667 - new log macros that shorten the size of the source code.
668 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
669 to send only zeros. With this workaround, para_audioc works
670 again.
671 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
672 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
673 (new entry), "snp" (set numplayed). Read the manual for more
674 information.
675
676
677 ---------------------------------------
678 0.2.1 (2005-08-15) "surreal experience"
679 ---------------------------------------
680
681 Here comes paraslash-0.2.1. It contains a couple of new features and,
682 surprise, only minor bug fixes.
683
684 - kill noisy mp3 debug message
685 - cleanup of the build system
686 - para_server and para_client directly use the crypto routines
687 of the openssl library rather than invoking the openssl command
688 line utitlity
689 - server/audiod: new option --user to switch to the given user
690 when invoked as root. Read the output of "para_server -h" for
691 more information.
692 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
693 status. Default: "para_audioc stat"
694 - sdl_gui: new option --pic_cmd to be used to download the picture.
695 Default: "para_client pic"
696 - audiod: 5 slots ought to be enough for everybody
697 - audiod: new status item: Uptime, kill hup command
698
699
700
701 ------------------------------------------
702 0.2.0 (2005-08-06) "distributed diffusion"
703 ------------------------------------------
704
705 After several month of increased development activity, paraslash-0.2.0
706 has arrived. It contains many new features and is much more
707 self-contained than the old 0.1.x series. Enjoy!
708
709
710 - para_server: fix hang on song change and crash on sighup.
711 Speed up mysql queries. The DIR_LIKE macro is gone.
712 - new executables: para_audiod, the local audio daemon that
713 starts playback (uses SCM_CREDENTIALS socket magic) and
714 para_audioc, the corresponding client.
715 - new executables: para_mp3dec/para_oggdec, two really teensy
716 decoders. para_mp3dec is based on libmad, para_oggdec requires
717 libvorbisfile.
718 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
719 they are now called para_send and para_recv respectively.
720 - documentation updates
721 - para_gui is themable. For now there is the default theme that
722 looks as before and the simple theme: blue and easy.
723 - gui: audio streaming is now handled by audiod. Time display shows
724 playback time rather than streaming time
725 - slider: update to libzmw-0.2.0
726 - para_krell: fix crash on server shutdown
727 - switch from gzip to bzip2
728
729
730 ----------------------------------------
731 0.1.7 (2005-04-18) "melting penetration"
732 ----------------------------------------
733
734 The main change in this release is clearly the oggvorbis rewrite,
735 but there are also lots of smaller changes. If you intend to use both
736 the mp3 and the ogg plugin, it is recommended to use software mixing,
737 e.g. the dmix plugin which is provided by ALSA.
738
739 - new executables: para_ovsend and para_ovrecv for sending/receiving
740 oggvorbis files via rtp. Requires the open rtp library. Get it at
741 http://www.linphone.org/ortp/
742 - rewrite of the ogg_vorbis core code
743 - configure detects libzmw and, if detected, includes
744 para_slider to the list of binaries to be built by make
745 - server stream writers read from their associated fifo rather
746 than from stdin
747 - slider: two new sliders, lastplayed and numplayed
748 - fix nasty double free bug which caused random segfaults in case of
749 mp3 files with invalid header information
750 - gui: new command line option: --stream_timeout=seconds to
751 deactivate a slot if it is idle for that many seconds (default=`5')
752 - diffstats
753
754
755 ---------------------------------------
756 0.1.6 (2005-03-05) "asymptotic balance"
757 ---------------------------------------
758
759 Only little user-visible changes in this release. Mainly bugfixes and
760 core code cleanup. This is probably the most stable version ever if you
761 stick to mp3...
762
763 - fix several memory leaks
764 - rename default name of mysql database from "music" to "paraslash".
765 Use para_server's --mysql_database option if you do not want to
766 rename your old database.
767 - rework ogg vorbis code
768 - make update command work on mysql servers with LOCAL_INFILE
769 disabled
770 - gui: improved stream I/O (slots)
771 - simplified audio format API
772 - para_pob_ogg is gone
773
774 ------------------------------------
775 0.1.5 (2004-12-31) "opaque eternity"
776 ------------------------------------
777
778 Let's slide gently into the new year.
779
780 - new: para_slider (not built automatically, type "make
781 para_slider" to build). A toy for those who always felt that
782 creating stream definitions is difficult. See screenshots,
783 README and FEATURES for more info.
784 - improved signal handling. Fixes server segfault on SIGHUP
785 for linux kernels newer than Aug 24 2004 and makes para_gui
786 race-free.
787 - reload database tool on SIGHUP
788 - improved help message for sl
789 - do not log "broken pipe" messages as errors. They are
790 perfectly ok.
791 - fix wrong error message on permission errors
792
793 -----------------------------------------
794 0.1.4 (2004-12-19) "tunneling transition"
795 -----------------------------------------
796
797 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
798 Hopefully, most of them got wiped out with this release. Some
799 enhancements went also in.
800
801 - improved error diagnostics for all commands
802 - stradd/picadd: overwrite previous contents if entry already
803 exists, rather than returning errors
804 - stradd: use current stream if invoked without args
805 - faster (and hopefully more stable) ogg-vorbis handling
806 - para_krell: reap children to avoid zombie-flooding in case
807 no server is running
808 - si: report also server pid
809 - server: don't busy-loop if dbtool reports only invalid files.
810 - gui: CTRL+C works again, fix stream_read command line option
811 - fix pic_add, hist
812 - fix mysql dbtool startup in case no database exists
813 - many small fixes and cleanups
814
815 ---------------------------------------
816 0.1.3: (2004-12-10) "vanishing inertia"
817 ---------------------------------------
818
819 Starting from this release, the database tools are integrated in the
820 server binary. This decreases server startup time, reduces code size
821 and speeds up database commands. However, the layout of the underlying
822 mysql database changed only slightly and 0.1.3 should be backwards
823 compatible in that respect.
824
825 Visible changes:
826
827 - If mysql is not detected at compile time, or fails to init
828 at runtime, fall back to the dopey database tool which should
829 always work.
830 - para_dbtool and dbtool.conf are gone. All mysql specific
831 options are read from server.conf and are prefixed by 'mysql_'.
832 - new command: cdt (change database tool)
833 - new command line option: dbtool (choose startup database tool)
834 - The name of current stream is now stored in the database,
835 so paraslash remembers its current stream when restarted.
836 - new command: csp (change stream and play)
837 - para_gui also reports current database tool and server uptime
838
839
840 -------------------------------------------
841 0.1.2: (2004-11-28) "spherical fluctuation"
842 -------------------------------------------
843
844 Point release before the big dbtool changes go in.
845
846 - dbtool: rename ca to cam (copy all meta data). It now also
847 copies numplayed and lastplayed time as well as the picture
848 id.
849 - fix endless-loop-bug caused by mp3 files with invalid header
850
851 -----------------------------------------
852 0.1.1: (2004-11-05) "floating atmosphere"
853 -----------------------------------------
854
855 - gkrellm plugin
856 - new dbtool command: mbox. Browse your sound-file collection
857 with your favorite mail reader.
858 - several small fixes
859
860 -------------------------------------
861 0.1.0: (2204-10-22) "rotating cortex"
862 -------------------------------------
863
864 - fix logging bug for loglevel > VERBOSE
865 - fix skip command
866 - correct timings for vbr mp3s
867 - modular audio format support
868 - ogg-vorbis support (experimental)
869 - new server option: autoplay
870
871 -----------------------------------------
872 0.0.99: (2004-07-25) "harmonic deviation"
873 -----------------------------------------
874
875 - rename projectname from icc to paraslash (play, archive, rate
876 and stream large audio sets happily)
877 - paraslash is no longer restricted to one particular audio
878 streaming software
879 - new dbtool commands (stradd, strq, strdel) for easy stream
880 managment w/o configuration file. That obsoletes stream_defs
881 file/config option for dbtool.
882 - picadd accepts jpeg data from stdin
883 - new server commands: ps (select previous stream), sc (song change)
884 - new default pictures for sdl_gui
885 - gui: new key_map option for binding commands and internal
886 functions to arbitrary keys, nice help screen, rip out
887 soundcard/linux specific stuff, avoid noise artefacts while jumping,
888 show silly logo on startup
889 - new executables: para_fade for fading volume, para_dbadm for
890 manipulating attributes
891 - cdb adds _all_ tables to mysql database
892 - revised and beautified documentation
893 - sample dbtool rewritten in C
894 - autoconf
895
896 ---------------------------------------------
897 0.0.98: (2003-12-26) "incremental smoothness"
898 ---------------------------------------------
899
900 - kick icecast in favour of poc. That removes some races and reduces
901 core code considerably.
902 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
903 give finer info on afs' status.
904 - gui can start decoder (see config options). Further new gui
905 commands: refresh (^L), jmp (F1-F10)
906 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
907 terminates gui. This fixes dead instances consuming memory
908 continuously.
909 - new dbtool command: verb for sending verbatim sql queries.
910 - fix pid_list races (by removing pid_list)
911 - codename funnies
912
913 --------------------
914 0.0.97: (2003-10-26)
915 --------------------
916
917 - installation prefix now defaults to /usr/local
918 - new commands for gui: snozze, sleep and reread config
919 - config file for gui and sdl_gui
920 - fix problems with filenames containing funny characters
921 (reported by Thomas Forell)
922 - improved signal handling for gui, now it rereads conf on SIGHUP
923 - new dbtool command: cdb (create database)
924 - switch from argtable to gengetopt
925 - major code cleanup and speed improvements
926 - fix several potential buffer overflows
927 - many small fixes and cleanups
928
929 -------------------

931 -------------------
932
933 - easy stream_defs syntax
934 - sdl_gui can display images associated to the file being played
935 - Major feature enhancements for icc_gui including dynamic text
936 placement and the top/bottom window design

938 well as for invalid picture pointers
939 - fix long outstanding case sensitivity bug
940 - many small fixes and cleanups
941
942 -------------------
943 0.0.95 (2003-06-29)
944 -------------------
945
946 - sdl gui runs much faster
947 - new dbtool command: ca (copy attributes)
948 - count and display number of times the song has been played

952 - decrease network traffic of stat
953 - fix zombie bug
954 - many small fixes and cleanups
955
956 -------------------
957 0.0.94 (2003-05-04)
958 -------------------
959
960 - new server command: ns (next stream)

970 -------------------
971
972 - colors for icc_gui
973 - icc_gui sets volume directly (linux only)
974 - proper locking that fixes some races
975 - fix security bug that caused commands to be executed even
976 with unsufficient permissions
977 - new command: hup to make all servers reread their configuration file
