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

927 well as for invalid picture pointers
928 - fix long outstanding case sensitivity bug
929 - many small fixes and cleanups
930
931 -------------------
932 0.0.95 (2003-06-29)
933 -------------------
934
935 - sdl gui runs much faster
936 - new dbtool command: ca (copy attributes)
937 - count and display number of times the song has been played
938 - new feature: scoring
939 - command line options for sdl_gui
940 - simpler syntax of streams file
941 - decrease network traffic of stat
942 - fix zombie bug
943 - many small fixes and cleanups
944
945 -------------------
946 0.0.94 (2003-05-04)
947 -------------------
948
949 - new server command: ns (next stream)
950 - new icc_gui command: c (change stream)

959 -------------------
960
961 - colors for icc_gui
962 - icc_gui sets volume directly (linux only)
963 - proper locking that fixes some races
964 - fix security bug that caused commands to be executed even
965 with unsufficient permissions
966 - new command: hup to make all servers reread their configuration file
967 - icecast meta data streaming
968 - many small fixes and cleanups
