33 0.5.3 (2014-08-01) "symbolic synchronization"
34 ---------------------------------------------
35
36 Not many new features, but lots of fixes and usability improvements.
37
38 - para_gui has been converted to use the paraslash scheduler.
39 - Various alsa-related fixes, mostly for the raspberry pi.
40 - Many scheduler improvements and cleanups.
41 - The test suite has been extended to include sanity checks
42 for the generated man pages.
43 - ao_writer fixes. This writer was in a quite bad shape. Many
44 serious bugs have been fixed.
45 - new audiod command: version.
46 - Minor improvements to the bitstream API.
47 - The cpsi command now prints a meaningful error message if
48 none of the given patterns matched any audio file.

54 0.5.2 (2014-04-11) "orthogonal interior"
55 ----------------------------------------
56
57 The new sync filter, the AES_CTR128 stream cipher and the overhauled
58 network code are the highlights of this release. It also includes a
59 fair number of smaller fixes and improvements not mentioned here.
60
61 - The new sync filter synchronizes playback between multiple
62 clients.
63 - Connections between para_server and para_client are now
64 encrypted by means of AES rather than RC4 if both sides
65 support it. RC4 is still available as a fallback. This
66 feature is fully transparent, i.e. no command line options
67 are necessary, and a client linked against openssl can
68 speak with a server linked against libgcrypt and vice versa.
69 - Major cleanup of the networking subsystem.
70 - Improvements to para_fade: the new set mode, multi-channel
71 initial volumes, better error logging.
72 - The man pages of para_audiod, para_filter, para_recv, and
73 para_write contain the relevant options for receivers, filters,
74 writers. This broke in 0.5.0.
75 - ogg/vorbis latency improvements.
76 - Improved user manual.
77 - Minor fixes to avoid clang warnings.

82 ------------------------------------------
83 0.5.1 (2013-12-20) "temporary implication"
84 ------------------------------------------
85
86 Lots of fixes and improvements all over the place, and a major overhaul
87 of the build system.
88
89 - Audiod improvements and fixes.
90 - Buffer tree robustness improvements.
91 - Cleanup of the mood subsystem.
92 - Fixes and cleanups for the flac decoder.
93 - Latency improvements for the ogg/opus decoder.
94 - Crypto support is now optional. On systems without
95 openssl/gcrypt, the build succeeds but para_server,
96 para_audiod, para_client won't be built.
97 - The build system now works for cross-compile setups.
98 - The dependency tree has been flattened, which speeds up
99 builds and avoids to recreate the man pages on every change.
100 - The error code helper has been rewritten from perl to C,
101 which further improves build time.
102 - Many small bugs in the build system have been identified
103 and fixed.

108 ----------------------------------------
109 0.5.0 (2013-08-23) "invertible validity"
110 ----------------------------------------
111
112 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
113
114 - The sideband compatibility code has been removed, hence
115 sideband connections (introduced in 0.4.11) are now mandatory.
116 - Addblob commands can produce output.
117 - The stat command no longer sends garbage when para_server was
118 compiled against libgcrypt.
119 - Dependencies for gengetopt files are computed automatically.
120 This eliminates a constant source of build bugs.
121 - The setatt command now accepts file name patterns rather than only
122 path names.
123 - overview.pdf is now based on dia, a simple diagram creation program.
124 The new version is much more detailed and contains descriptions of
125 the various programs of the paraslash package.
126 - The separator of all multi-word options has been changed from
127 underscore to dash. For example --log_color becomes --log-color.
128 - Overhauled web pages and the new logo.

133 --------------------------------------
134 0.4.13 (2013-07-29) "spectral gravity"
135 --------------------------------------
136
137 One more 0.4.x release before the API-breaking changes for 0.5.0 go
138 in. The main features of this release are the ogg/opus audio format,
139 and UTF-8 support, but it includes also tons of other improvements
140 and fixes all over the place.
141
142 - New audio format: ogg/opus.
143 - UTF8 support for para_gui and the mp3 audio format handler.
144 - Scheduler improvements and fixes.
145 - The obsolete gettimeofday() function has been replaced
146 by clock_gettime() on systems which support it.
147 - Speed and usability improvements for para_gui.
148 - para_client now restores the fd flags of stdin and stdout
149 on shutdown.
150 - Improved manual pages.
151 - Consistent version strings for all executables.
152 - Reduced dependencies on generated files result in fewer
153 recompilations on changes.
154 - Performance improvements for the compress filter.
155 - Improved downloads web page.
156
157 -----------------------------------------
158 0.4.12 (2012-12-20) "volatile relativity"
159 -----------------------------------------
160 The new command line player, the resample filter, ALSA support for
161 para_fade, and the improved build system are the highlights of this
162 release which probably marks the end of the 0.4.x series.
163
164 - The afh receiver and the para_play executable.
165 - The resample filter: A sample rate converter based on
166 libsamplerate.
167 - The "versions" directory has been removed from the master
168 branch. The tarballs of the old releases are now available
169 in the new "releases" branch.
170 - Overhaul of the build system: All generated files are now
171 written to the "build" directory.
172 - The modular mixer API and the alsa mixer.
173 - Minor fixes for the osx writer.
174
175 --------------------------------------
176 0.4.11 (2012-07-20) "mutual diversity"
177 --------------------------------------
178
179 The major feature in this release is the new sideband API for
180 client-server communication. This API will be used exclusively starting
181 with 0.5.0, which breaks backward compatibility but allows to get rid
182 of quite some compatibility code. Other noteworthy changes include
183 decoder latency improvements and a long-standing bug fix for the
184 ALSA writer.
185
186 - Sideband connections: If both para_server and para_client
187 support this feature, data is sent as a multiplexed stream.
188 - The --no_default_filters option of para_filter has been
189 removed.
190 - Several fixes and latency improvements to various decoders.
191 - The ALSA writer now limits the prebuffer time to 500ms.
192 - Documentation improvements.
193 - Overhaul of the command_util.sh script.
194 - Fixes for some minor problems found by the clang analyzer.
195 - Compiles (almost) without warnings on gcc-3.
196 - Robustness improvements of the buffer tree code.
197
198 ------------------------------------------
199 0.4.10 (2012-03-30) "heterogeneous vacuum"
200 ------------------------------------------
201
202 Nothing earth-shaking in this release, but quite a few usability
203 improvements and the usual mix of cleanups and fixes.
204
205 - The --no_default_filters option of para_filter has been
206 deprecated. It still works but has no effect and will be
207 removed in the next version.
208 - para_gui now prints also the stderr output of the executing
209 command in the bottom window.
210 - Cleanup and consolidation of the various wrappers for
211 write(), writev(), send() and friends.
212 - The obscure error messages on mmap() failures have been
213 replaced by meaningful messages. This affects mainly
214 para_afh.
215 - para_audioc: Cleanups and memory leak fixes.
216 - Test 0004-server no longer fails if para_server is not
217 being built.
218 - New configure options: --with-id3tag-{headers,libs}.
219
220 -------------------------------------
221 0.4.9 (2011-12-06) "hybrid causality"
222 -------------------------------------
223
224 Support for another audio format, interactive mode for para_client
225 and para_audiod and many small improvements/fixes all over the place.
226
227 - Support for flac, the free lossless audio codec.
228 - Fix for an endless loop in the mp3 decoder for certain
229 (corrupt) mp3 files.
230 - When executed without specifying a command, para_client
231 and para_audioc start an interactive shell (requires
232 libreadline being installed). The interactive mode offers
233 full tab completion and command line history.
234 - autogen.sh now detects a distcc setup and adjusts the
235 parameter for the -j option of make accordingly.
236 - Shared memory areas are no longer restricted to 64K. We now
237 detect the maximal size of a shared memory area at runtime.
238 - cleanup of the internal uptime API.
239 - para_server prefaults the mmapped audio file to avoid
240 delays on slow media.
241 - A new test for the test-suite that exercises the
242 communication between para_server and para_audiod.
243 - The alsa writer eats up less CPU cycles when configured to
244 use the DMIX plugin.
245 - Simplified and unified receiver code.
246 - Makefile cleanups.
247 - Commands which print a list of matching audio files now
248 emit a meaningful error message if no audio file matched the
249 given pattern(s).
250
251 --------------------------------------
252 0.4.8 (2011-08-19) "nested assignment"
253 --------------------------------------
254
255 Gcrypt support, the overhauled osx writer and regex format specifiers
256 are the highlights of this release.
257
258 - support for libgcrypt as a drop-in replacement for openssl.
259 Run configure --enable-cryptolib=gcrypt to link against
260 libgcrypt. The two crypto implementations are compatible to
261 each other, i.e. a para_client executable linked against
262 gcrypt can connect to para_server linked against libssl
263 and vice versa.
264 - Rewrite of the osx writer (output plugin for Mac OS).
265 - audiod: The format specifier for receivers, filters and
266 writers is now treated as a regular expression. This allows
267 to replace 5 lines in the config file (one for each audio
268 format) by one single line. See the manual for details.
269 - The *.cmdline.[ch] files are no longer contained in the released
270 tarballs. This reduces the size of the tarballs but requires
271 gengetopt to build the tarball.
272 - Compiles cleanly also with llvm/clang.
273 - Corrupt mp3 files are handled more gracefully.
274 - The alsa writer uses poll fds instead of computing timeouts.
275 - Cleanup of the generic writer API.
276 - sched: Optimized zero timeouts.
277 - vss timeout cleanups.
278 - oggdec fixes and improvements.
279
280 --------------------------------------
281 0.4.7 (2011-06-01) "infinite rollback"
282 --------------------------------------
283
284 The new ao writer, support for ssh RSA keys and a couple of other
285 enhancements.
286
287 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
288 platforms through the libao audio library.
289 - Support for RSA keys generated with ssh-keygen.
290 - configure: improved options for ogg/vorbis/speex.
291 - The git version reported by --version always matches HEAD.
292 - The autogen script detects the number of processors and
293 runs a parallel make if possible.
294 - Major cleanup of the crypto API.
295 - Documentation updates.
296
297 ------------------------------------------
298 0.4.6 (2011-03-31) "deterministic entropy"
299 ------------------------------------------
300
301 Lots of ogg/vorbis improvements, the new test suite, enhancements
302 for para_gui and a fair amount of other bug fixes.
303
304 - For DCCP/OGG streams the audio file header is only sent once
305 at the beginning of the stream rather than periodically
306 every five seconds. This reduces network traffic and the
307 FEC group size.
308 - The vorbis comment header is replaced by an empty dummy header
309 before the header is sent over the network. This also results in
310 less network traffic and smaller FEC groups.
311 - The new "test" make target allows to perform some sanity checks prior
312 to installing the package.
313 - ogg timing fixes and performance improvements
314 - Scheduler improvements
315 - Proper exit codes for para_write
316 - para_gui: New option --theme to select a startup theme. Several
317 other improvements and fixes.
318 - aacdec error message cleanups
319 - simplified color error handling
320
321 --------------------------------------------
322 0.4.5 (2010-12-17) "symmetric randomization"
323 --------------------------------------------
324
325 Bug fixes, internal cleanups and variable-sized FEC slices.
326
327 - Contains a fix for an invalid-free-bug in the ogg audio format
328 handler code.
329 - Switching off the DCCP sender works again.
330 - para_audiod handles crashes of para_server more robustly.
331 - Internal scheduler and writer cleanups.
332 - Reduced latency due to variable-sized FEC slices.
333 - Improved documentation and error diagnostics.
334 - The build of para_server is now optional, allowing the build
335 to succeed in case libosl is not installed.
336
337 ------------------------------------------
338 0.4.4 (2010-08-06) "persistent regularity"
339 ------------------------------------------
340
341 Support for yet another audio format, para_write improvements and
342 bug fixes.
343
344 - Support for the speex codec.
345 - Support for sample formats other than 16 bit little endian.
346 - error2.h is now created by a perl script which speeds up configure
347 considerably.
348 - Fix a bug in the aac decoder which could lead to segfaults in
349 para_filter/para_audiod.
350 - Fixes for autoconf-2.66.
351
352 ----------------------------------------
353 0.4.3 (2010-07-05) "imaginary radiation"
354 ----------------------------------------
355
356 Many improvements for the DCCP and the UDP transport, the new user
357 manual and the usual mix of bug fixes and internal improvements.
358
359 - FEC support for the DCCP sender (Gerrit Renker). The new
360 --dccp_max_slice_size, --dccp_data_slices_per_group and
361 --dccp_slices_per_group options can be used to set the FEC
362 parameters for the DCCP transport.
363 - DNS lookups for UDP targets (Gerrit Renker).
364 - The new user manual replaces the README, README.afs, REQUIREMENTS
365 and INSTALL documents.
366 - Fix an end-of-file detection bug in the oggdec filter.
367 - The new nonblock API.
368 - Both options of the oggdec filter have been removed.
369 - New debug mode for the internal scheduler.
370
371 ------------------------------------------
372 0.4.2 (2010-04-23) "associative expansion"
373 ------------------------------------------
374
375 It's been some time since the last release, but finally here is
376 paraslash-0.4.2. The bulk of the changes comes from the new buffer
377 tree API, but there are changes all over the tree. Mainly performance
378 and usability improvements, but also quite some bug fixes.
379
380 - The new buffer tree API.
381 - DCCP: Support for CCID negotiation (Gerrit Renker).
382 - UDP robustness fixes.
383 - The --bufsize option for mp3dec is gone as it no longer makes sense
384 for the new buffer tree API.
385 - Fix audible buffer underruns for wma streams.
386 - The alsa writer no longer prints meaningless underrun durations.
387 - audiod: Defaults work also for udp streams. If no filter is
388 given for an audio format that is received via upd, fecdec is
389 automatically added as the first filter (along with the decoder).
390
391 ---------------------------------------
392 0.4.1 (2009-12-22) "concurrent horizon"
393 ---------------------------------------
394
395 Support for another audio format, minor feature enhancements and lots of bug
396 fixes. All fixes that have been accumulated in the maint branch (in particular
397 those mentionened in the 0.3.6 release notes) appear in this release as well.
398
399 - wma support.
400 - new afh option: --human to activate human-readable output.
401 - new server/audiod option: --log-timing to print timing information.
402 - build system improvements.
403 - source code documentation updates.
404
405 -------------------------------------
406 0.3.6 (2009-12-07) "cubic continuity"
407 -------------------------------------
408
409 Quite a few bugs have been found and fixed since 0.3.5, so here's
410 another 0.3.x release. No new features.
411
412 - Always check return value of malloc().
413 - ogg vorbis/FEC: Do not write garbage after the audio file header.
414 - exit if root privileges could not be dropped.
415 - FEC: Fix computation of extra slices.
416 - oss: Fix check for empty input buffer.
417 - Avoid buffer underruns due to filter chain output buffer constraints.
418 - server: Fix assignment of afs_pid.
419 - Don't panic if the afs database contains unknown audio formats.
420 - http/dccp: Do not send the audio file header twice.
421 - FEC: Timing improvements.
422
423 ----------------------------------------------
424 0.4.0 (2009-11-10) "simultaneous independence"
425 ----------------------------------------------
426
427 Two significant changes which require the new version number: The
428 improved authentication dialog and the fact that the database code
429 has been moved to a library, libosl. To use the new version, you have
430 to generate new RSA keys, see INSTALL for details. A shell script is
431 provided for conversion of the 0.3 database to the new 0.4 format.
432
433 - stronger crypto for client authentication
434 - the database code has been moved to a library
435 - improved status item handling
436 - cleanup of the build system
437 - The "-V" option now also prints the git version
438 - the new parser-friendly listing mode for the ls and stat commands
439 - mandatory rc4 encryption
440 - major audio format handler cleanups
441 - (id3,...) tags are no longer stored as a combined string in the database
442 - new mood methods: artist_matches, title_matches, comment_matches,
443 album_matches, year_maches, year.
444
445 --------------------------------------------
446 0.3.5 (2009-09-21) "symplectic separability"
447 --------------------------------------------
448
449 Full client support for *BSD Unixes, complete re-write of the ogg
450 vorbis audio format handler, various improvements all over the place
451 and the usual mix of bugfixes. This release marks the end of the 0.3
452 series if no serious problems show up.
453
454 - the new oss writer (supported on *BSD and Linux)
455 - rewrite of the ogg vorbis audio format handler. It's
456 recommended to replace the chunk tables of existing ogg
457 vorbis files in the afs database by re-adding these files
458 with "add -f".
459 - support for netmask subsets (Gerrit Renker)
460 - the new prebuffer filter
461 - improved signal handling
462 - variable fec output buffer size
463 - improved FEC timing fixes audible buffer underruns in UDP mode
464 - --log_color actually works
465 - new ls option: -d (print dates as seconds after the epoch)
466 - update to gengetopt 2.22.2
467 - support for RSA keys of size > 512 bits
468 - new option "mixer_channel" for para_fade
469
470 -----------------------------------------
471 0.3.4 (2009-05-07) "elliptic inheritance"
472 -----------------------------------------
473
474 The new udp sender, forward error correction, colored logs and various
475 other improvements. As the udp sender does not depend on any special
476 libraries, it is built unconditionally.
477
478 - The udp sender replaces the ortp sender. The new code uses forward
479 error correction to protect against packet losses. Many thanks to
480 Gerrit Renker for providing ipv6 support.
481 - The default port for udp streaming now defaults to 8000, like
482 for the http and the dccp senders/receivers.
483 - Loglevels are now specified as symbolic names, e.g.
484 "--loglevel info".
485 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
486 - para_server/para_audiod: Color support for log messages.
487 - new options for mp3dec: --ignore-crc, --bufsize
488 - new audiod option: --config-file.
489 - gengetopt cleanups.
490 - Improved help/man pages: The documentation of para_audiod,
491 para_recv, para_filter and para_write now also contains
492 all options of the available receivers/filters/writers. The
493 man page of para_fade contains a description of the different
494 modes of operation.
495 - More source code documentation.
496 - vss timing fixes.
497
498 --------------------------------------------
499 0.3.3 (2008-12-01) "axiomatic perspectivity"
500 --------------------------------------------
501
502 Internal code cleanups, bug fixes, improved tag handling and the new
503 amplification filter.
504
505 - para_server uses the generic scheduling code.
506 - overhaul of the virtual streaming system.
507 - mp3: id3 version 2 support via libid3tag (optional)
508 - ogg: vorbis comment support.
509 - aac meta info support.
510 - mp3 audio format handler cleanups.
511 - new filter: "amp" to amplify the amplitude of the audio stream
512 - new status item/database entry: amplification. It is
513 used by the amp filter to pre-amplify the audio stream.
514 - fix a close-without-open bug in para_write.
515 - fix a bug in com_init() which was introduced in 0.3.2.
516 - better error diagnostics for para_client.
517
518 -----------------------------------------
519 0.3.2 (2008-04-11) "probabilistic parity"
520 -----------------------------------------
521
522 The new para_afh executable, scheduling and documentation improvements.
523
524 - new ls option: -lc (list chunk table)
525 - new executable: para_afh, the stand-alone audio file handler tool
526 - afs commands can send output more than SHMMAX (32MB on Linux). This
527 also reduces the memory usage of commands that produce large amounts
528 of output.
529 - major scheduler and audiod cleanups.
530 - more detailed and much nicer man pages.
531
532 ---------------------------------------
533 0.3.1 (2008-02-23) "liquid interaction"
534 ---------------------------------------
535
536 A mix of cleanups, bug fixes, improvements, and some new features. No
537 significant changes to the new database (osl) code, which is generally
538 a good sign.
539
540 - Share some similar/duplicate code between the http and the
541 dccp sender.
542 - Generic access control lists for paraslash senders.
543 - dccp sender: Access control lists, connection limiting and support
544 for the allow,deny,on,off,help sender commands.
545 - The default dccp port changed from 5001 to 8000 (suggested by
546 Gerrit Renker).
547 - para_server starts even if not all public keys could be loaded.
548 - Audiod performance improvements.
549 - fix a bug in the "off" command of the http sender.
550 - fix some fd and memory leaks.
551 - Update to gengetopt-2.22.
552
553 -------------------------------------
554 0.3.0 (2008-01-12) "solar saturation"
555 -------------------------------------
556
557 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
558
559
560 Usually one might expect lots of new features AND a big increase in size
561 for a major release like this.
562
563 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
564 ever. The decrease in size is mostly due to the removal of some
565 graphical tools (which were only quick hacks anyway). But also the
566 fact that the mysql code is gone cuts down the size a bit.
567
568 Being independent of mysql comes at a cost: The fact that paraslash
569 now contains its own database (the object storage layer, osl) increases
570 the (stripped) binary size of para_server by ~50K on i386.
571
572 - no more restrictions on unique basenames.
573 - independent of mysql: The new self-contained object
574 storage layer (osl) replaces the mysql database.
575 - New executable para_fsck: Check integrity of osl tables.
576 - Lyrics support.
577 - Reliable audio file move/rename detection.
578 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
579 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
580 Solaris (sparc64).
581 - the new osl-based audio file selector (afs) replaces the random,
582 the playlist and the mysql selector of paraslash-0.2.x.
583 - IPv6 support (thanks to Gerrit Renker).
584 - paraslash-0.2.x streams are now called "moods". Writing
585 0.3.x-mood definitions should be both easier and more
586 powerful than writing 0.2.x-stream definitions.
587 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
588 been removed. The world is a better place without them. However,
589 para_gui is still there.
590 - afs tracks audio file selection also in playlist mode.
591 - few easy-to-use afs commands replace the many not-so-easy-to-use
592 mysql commands (and are available also in playlist mode).
593 - Improved error subsystem.
594 - The earth-shaking new logo.
595
596 -----------------------------------------
597 0.2.17 (2007-11-20) "isotropic threshold"
598 -----------------------------------------
599
600 Mainly bugfixes and cleanups in this version which marks the end of
601 the 0.2.x series if no serious bugs show up after the release.
602
603 - mysql_selector: fix a locking bug.
604 - universal chunk queueing.
605 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
606 to Gerrit Renker).
607 - be more carful wrt. signed vs. unsigned argument passing.
608 - cleanup error.h and fix some references to invalid error
609 codes.
610 - update to gengetopt-2.21.
611 - update to ortp-0.13.1.
612 - autoconf: extend checks for headers, library functions and
613 compiler characteristics.
614 - Fix streaming of large mp3 files.
615 - Fix an off-by-one bug in playlist handling.
616
617 --------------------------------------
618 0.2.16 (2007-04-05) "neural discharge"
619 --------------------------------------
620
621 The main change in this release is the major audio format handler
622 cleanup which removes some similar/duplicate code and makes it easier
623 to implement plugins for other audio formats. Of course, the usual mix
624 of other improvements/changes/bugfixes also made it into the release.
625
626 - simplified audio format handlers (most of the handling functions
627 were moved one layer up to the virtual streaming system).
628 - para_server uses mmap to read audio files
629 - repositioning of mp3 streams is much faster, in particular for
630 jumping near the end of large mp3 files.
631 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
632 and AFS_WRITE.
633 - fix a bug in para_filter that caused decoding of aac files
634 to start only after a few seconds.
635 - fix osx_writer hangs
636 - simplified dccp code (thanks to Gerrit Renker)
637 - the compress filter works also on big endian systems (ppc)
638
639 -----------------------------------------
640 0.2.15 (2007-02-16) "inductive resonance"
641 -----------------------------------------
642
643 Minor improvements, more documentation and a bunch of bug fixes.
644
645 - para_server: The server.users file is only read once on server
646 startup rather than for each connection
647 - mp3dec: Fix decoding of corrupt mp3 files
648 - afs (audio file sender) is now called vss (virtual streaming
649 system). Consequently, the permission flags specified in
650 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
651 become VSS_READ and VSS_WRITE respectively.
652 - para_audiod/para_filter: Fix a bug that caused the last chunk
653 of audio data not being written under certain circumstances
654 - audiod: compute the difference of server time and local time
655 correctly
656 - para_server/para_audiod: Fix some memory leaks
657 - documentation improvements
658 - configure.ac: fix checks for para_krell
659 - new man pages
660
661 -------------------------------------------
662 0.2.14 (2006-10-15) "transient singularity"
663 -------------------------------------------
664
665 The only major enhancement of this version is the osx writer which completes
666 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
667 until now for reasons beyond the scope of this changelog entry.
668
669 - new output plugin for Mac Os: the osx writer
670 - rename configure command line options from --enable-xxx-headers to
671 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
672 - configure: new command line options: --with-mad-headers,
673 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
674 - some robustness fixes
675 - dymamic audio format recognition for audiod
676 - para_server: new command line option: --autoplay_delay
677 - para_audiod: new command line option: --clock_diff_count
678
679 ---------------------------------------
680 0.2.13 (2006-07-14) "sonic convolution"
681 ---------------------------------------
682
683 A bunch of new features and core changes.
684
685 - the new paraslash scheduler, short and sweet.
686 - Support for m4a/mp4 files via the new aac audio format
687 handler/filter (requires libfaad).
688 - each writer has its own command line parser, just like
689 para_recv and para_filter.
690 - para_client and para_audioc use the error subsystem
691 - writers are integrated in para_audiod (currently linux-only)
692 - para_client is integrated in para_audiod
693 - random/playlist selector: improved info strings
694 - new audiod commands: tasks, kill
695 - update to libortp-0.10.1
696 - para_fade: wake time defaults to 8 hours from now
697 - update to autoconf-2.60
698
699 ------------------------------------------
700 0.2.12 (2006-05-12) "oriented abstraction"
701 ------------------------------------------
702
703 Many user-visible changes in this release and lots of new
704 features:
705
706
707 - the new optional dccp sender/receiver. It uses the datagram
708 congestion control protocol. You'll need a fairly new kernel
709 for this.
710 - paraslash works on Mac OS X (thanks to Gerd Becker)
711 - para_play renamed to para_write
712 - modular output plugin design (writers) for para_write
713 - new file_writer output plugin for para_write
714 - compress filter speed improvements
715 - update to libortp-0.9.1
716 - update to gengetopt-2.17rc
717 - para_client no longer depends on libreadline (as the
718 code for the interactive mode was removed).
719 - gcc-2-95 is no longer a supported compiler. It may still
720 work, but it gets no more testing.
721 - the tarball no longer contains the screenshot images which
722 reduces its size quite a bit.
723 - configure: new command line options: --enable-mysql-headers
724 and --enable-mysql-libs
725
726 ------------------------------------
727 0.2.11 (2006-03-11) "atomic duality"
728 ------------------------------------
729
730 Here it is, the first paraslash release developed with git. There
731 are fairly many user-visible changes in this release. As two out of
732 the three "database tools" of paraslash don't use a database at all,
733 they are now called "audio file selectors" instead.
734
735
736 - the cdt command (change database tool) becomes chs (change
737 selector)
738 - no more colon separators: The syntax of some options of
739 para_audiod and para_filter have changed. Use --help for
740 more info (and some examples).
741 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
742 - switch from cvs to git (should've done that earlier)
743 - the new ipc subsystem
744 - new audio file selector: playlist
745 - para_server: the dopey selector is now called "random",
746 and is the default selector. Use the --selector option to
747 choose another selector at startup, or the chs command to
748 change the selector at runtime.
749 - X86_64 fixes (thanks to Steffen Klassert)
750 - para_play fixes
751
752 --------------------------------------
753 0.2.10 (2006-02-17) "cyclic attractor"
754 --------------------------------------
755
756 Huge documentation update, a scrollable window for para_gui, ortp
757 improvements, and of course many small fixes not mentioned here.
758 The diffstat below is rather misleading as most insertions are due
759 to the new source documentation.
760
761 - autoconf cleanup
762 - para_server also uses the new error subsystem
763 - lots of new documentation (UTSL)
764 - gui improvements:
765 - keysyms for cursor keys and for next/previous page keys
766 - scrollable output window
767 - new internal commands: scroll up/down, page up/down
768 - fix color of command output.
769 - ortp: the --chunk_time and --header flags are no longer needed
770 for para_recv/para_audiod as this information is now encoded in
771 each rtp packet sent by para_server.
772
773 -------------------------------------------
774 0.2.9 (2006-01-24) "progressive turbulence"
775 -------------------------------------------
776
777 Internal audiod receivers/filters, the new error subsystem and
778 a lot of small improvements.
779
780 - para_recv and para_filter are integrated into the para_audiod
781 binary, i.e. audiod no longer spawns a new process for
782 each receiver/filter. As para_recv and para_filter might be
783 useful as standalone programs, they still get built (linked
784 against the same object files that are also used for audiod).
785 - further ortp timing improvements should reduce the CPU usage
786 of the ortp receiver.
787 - improved audio grabbing. The 'grab' command of para_audiod
788 has its own set of command line options. Read the output of
789 "para_audioc help grab" for more info.
790 - oggdec: configurable input prebuffer size.
791 - the new error subsystem gives better error diagnostics
792 and reduces code size.
793
794 -----------------------------------------
795 0.2.8 (2006-01-02) "dynamic accumulation"
796 -----------------------------------------
797
798 The new modular filter design and the para_play-hangs bugfix.
799
800 - new executable: para_filter. It combines para_mp3dec,
801 para_oggdec and para_compress. It also adds a further filter
802 type, wav, that just inserts a wave header at the desired point
803 of the filter chain. All 'piping' is done in-memory (i.e. no
804 read/write operations are used).
805 - para_play: fix a stupid bug that caused it to hang under
806 certain circumstances.
807
808 -------------------------------------------
809 0.2.7 (2006-12-27) "transparent invariance"
810 -------------------------------------------
811
812 Not many user-visible changes but a fair amount of internal improvements.
813
814
815 - The http sender buffers data if it can not be sent
816 out immediately (because the socket is not writable). This
817 should prevent para_server from shutting down the connection
818 too early on a loaded network.
819 - para_play also prebuffers data if it is told to start at a
820 future time by the --start_time option.
821 - The return of para_recv: It combines para_ortp_recv and
822 para_http_recv. Use the --receiver option to switch between
823 the two. para_recv builds without libortp, but contains
824 only the http receiver in this case.
825 - update to ortp 0.8.1. As this ortp release contains incompatible
826 changes, para_recv-0.2.7 won't link against older ortp libs.
827 - improved ortp timings.
828 - use of gcc-extensions that #define away for non-gcc and
829 gcc < 3.0.
830
831 -------------------------------------------
832 0.2.6 (2005-10-29) "recursive compensation"
833 -------------------------------------------
834
835 Transparent session encryption (uses openssl's Alleged RC4 cipher),
836 the internal find command and several other improvements and cleanups.
837
838 - Encrypt the session if encryption is requested by the client
839 (default for para_client 0.2.6). This is backwards
840 compatible, so older clients can still connect to para_server
841 0.2.6. Use the new client option --plain to request an
842 uncrypted session (off by default, must be set to on in
843 order to connect to para_server 0.2.x with 0 <= x <= 5).
844 - para_server uses an internal function to locate audio files
845 rather than calling find(1). The server option
846 --mysql_audio_file_dir replaces --mysql_find_cmd.
847 - documentation update
848 - man pages
849 - header file cleanup
850 - para_client code cleanup
851 - para_gui: faster display of output of display commands
852
853 ------------------------------------------
854 0.2.5 (2005-10-13) "aggressive resolution"
855 ------------------------------------------
856
857 This release adds internal senders, i.e. no more external programs are
858 spawned for sending out the audio data. There are two different senders
859 available: The http sender and the ortp sender (former para_send which
860 is no longer needed).
861
862 The new sender code has a plugin-like design so it can be easily
863 extended should there be be any future need for supporting another
864 network streaming protocol. All senders are completely independent of
865 each other. In particular, the http and the ortp sender can operate
866 in parallel.
867
868 - new server command: sender to control senders at runtime.
869 Read the output of "para_server -h" and "para_client help
870 sender" for more information.
871 - para_recv renamed to para_ortp_recv
872 - new executable: para_http_recv, a simple command line
873 http receiver.
874 - major afs/mp3/ogg code simplifications due to internal
875 senders.
876 - ogg timing improvements
877 - fix several minor memory leaks (found by valgrind)
878 - empty stream definitions work again
879 - com_ne(): ignore errors on remove
880 - audiod: fix segfault on server restart
881
882 ---------------------------------------
883 0.2.4 (2005-09-21) "toxic anticipation"
884 ---------------------------------------
885
886 Several small improvements, fixes and the new grab command.
887
888 - audiod:
889 - new command: "grab" to grab the output of the stream reader
890 or any filters. Read the output of "para_audioc help grab"
891 for more information.
892 - fix memory leak
893 - code cleanup
894 - audioc: new command line option: --bufsize to specify a
895 buffer size different from the default size 8192.
896 - improved error diagnostics for para_play.
897 - new configure option: --enable-ssldir so search for openssl in
898 non-standard places
899 - sdl_gui: Make it look nice again for 1024x768
900 - server: report total size of memory allocated with sbrk by malloc,
901 new command line option: --announce_time
902
903 -----------------------------------------
904 0.2.3 (2005-09-01) "hydrophilic movement"
905 -----------------------------------------
906
907 Two new executables and major feature enhancements.
908
909 - audiod filters: It is now possible to specify arbitrary many
910 (including none) filters for each supported audio
911 format. This can be used e.g. for normalizing volume,
912 transforming or grabbing the audio stream, or for using
913 visualizers. Read the output of "para_audiod -h" for the
914 syntax of the new --filter_cmd option.
915 - new executable: para_play, a tiny alsa player. It
916 can play wave files or raw pcm (16 bit little endian)
917 from stdin.
918 - new executable: para_compress, a dynamic range compressor
919 intended to keep audio output at a consistent volume. Derived
920 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
921 - audiod: New option: --stream_delay. This can be used in
922 a local network to syncronize the audio output of all
923 clients that play the same stream.
924
925 ------------------------------------------
926 0.2.2 (2005-08-19) "tangential excitation"
927 ------------------------------------------
928
929 Mostly internal changes in this release, but also some new commands
930 for the mysql database tool.
931
932 - cleanup exec.c, fix para_exec bug
933 - compile time loglevel (log messages below the given level
934 won't be compiled in, which reduces the size of the
935 resulting binaries)
936 - new log macros that shorten the size of the source code.
937 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
938 to send only zeros. With this workaround, para_audioc works
939 again.
940 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
941 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
942 (new entry), "snp" (set numplayed). Read the manual for more
943 information.
944
945 ---------------------------------------
946 0.2.1 (2005-08-15) "surreal experience"
947 ---------------------------------------
948
949 Here comes paraslash-0.2.1. It contains a couple of new features and,
950 surprise, only minor bug fixes.
951
952 - kill noisy mp3 debug message
953 - cleanup of the build system
954 - para_server and para_client directly use the crypto routines
955 of the openssl library rather than invoking the openssl command
956 line utitlity
957 - server/audiod: new option --user to switch to the given user
958 when invoked as root. Read the output of "para_server -h" for
959 more information.
960 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
961 status. Default: "para_audioc stat"
962 - sdl_gui: new option --pic_cmd to be used to download the picture.
963 Default: "para_client pic"
964 - audiod: 5 slots ought to be enough for everybody
965 - audiod: new status item: Uptime, kill hup command
966
967 ------------------------------------------
968 0.2.0 (2005-08-06) "distributed diffusion"
969 ------------------------------------------
970
971 After several month of increased development activity, paraslash-0.2.0
972 has arrived. It contains many new features and is much more
973 self-contained than the old 0.1.x series. Enjoy!
974
975
976 - para_server: fix hang on song change and crash on sighup.
977 Speed up mysql queries. The DIR_LIKE macro is gone.
978 - new executables: para_audiod, the local audio daemon that
979 starts playback (uses SCM_CREDENTIALS socket magic) and
980 para_audioc, the corresponding client.
981 - new executables: para_mp3dec/para_oggdec, two really teensy
982 decoders. para_mp3dec is based on libmad, para_oggdec requires
983 libvorbisfile.
984 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
985 they are now called para_send and para_recv respectively.
986 - documentation updates
987 - para_gui is themable. For now there is the default theme that
988 looks as before and the simple theme: blue and easy.
989 - gui: audio streaming is now handled by audiod. Time display shows
990 playback time rather than streaming time
991 - slider: update to libzmw-0.2.0
992 - para_krell: fix crash on server shutdown
993 - switch from gzip to bzip2
994
995 ----------------------------------------
996 0.1.7 (2005-04-18) "melting penetration"
997 ----------------------------------------
998
999 The main change in this release is clearly the oggvorbis rewrite,
1000 but there are also lots of smaller changes. If you intend to use both
1001 the mp3 and the ogg plugin, it is recommended to use software mixing,
1002 e.g. the dmix plugin which is provided by ALSA.
1003
1004 - new executables: para_ovsend and para_ovrecv for sending/receiving
1005 oggvorbis files via rtp. Requires the open rtp library. Get it at
1006 http://www.linphone.org/ortp/
1007 - rewrite of the ogg_vorbis core code
1008 - configure detects libzmw and, if detected, includes
1009 para_slider to the list of binaries to be built by make
1010 - server stream writers read from their associated fifo rather
1011 than from stdin
1012 - slider: two new sliders, lastplayed and numplayed
1013 - fix nasty double free bug which caused random segfaults in case of
1014 mp3 files with invalid header information
1015 - gui: new command line option: --stream_timeout=seconds to
1016 deactivate a slot if it is idle for that many seconds (default=`5')
1017 - diffstats
1018
1019 ---------------------------------------
1020 0.1.6 (2005-03-05) "asymptotic balance"
1021 ---------------------------------------
1022
1023 Only little user-visible changes in this release. Mainly bugfixes and
1024 core code cleanup. This is probably the most stable version ever if you
1025 stick to mp3...
1026
1027 - fix several memory leaks
1028 - rename default name of mysql database from "music" to "paraslash".
1029 Use para_server's --mysql_database option if you do not want to
1030 rename your old database.
1031 - rework ogg vorbis code
1032 - make update command work on mysql servers with LOCAL_INFILE
1033 disabled
1034 - gui: improved stream I/O (slots)
1035 - simplified audio format API
1036 - para_pob_ogg is gone
1037
1038 ------------------------------------
1039 0.1.5 (2004-12-31) "opaque eternity"
1040 ------------------------------------
1041
1042 Let's slide gently into the new year.
1043
1044 - new: para_slider (not built automatically, type "make
1045 para_slider" to build). A toy for those who always felt that
1046 creating stream definitions is difficult. See screenshots,
1047 README and FEATURES for more info.
1048 - improved signal handling. Fixes server segfault on SIGHUP
1049 for linux kernels newer than Aug 24 2004 and makes para_gui
1050 race-free.
1051 - reload database tool on SIGHUP
1052 - improved help message for sl
1053 - do not log "broken pipe" messages as errors. They are

1056
1057 -----------------------------------------
1058 0.1.4 (2004-12-19) "tunneling transition"
1059 -----------------------------------------
1060
1061 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1062 Hopefully, most of them got wiped out with this release. Some
1063 enhancements went also in.
1064
1065 - improved error diagnostics for all commands
1066 - stradd/picadd: overwrite previous contents if entry already
1067 exists, rather than returning errors
1068 - stradd: use current stream if invoked without args
1069 - faster (and hopefully more stable) ogg-vorbis handling
1070 - para_krell: reap children to avoid zombie-flooding in case
1071 no server is running
1072 - si: report also server pid
1073 - server: don't busy-loop if dbtool reports only invalid files.
1074 - gui: CTRL+C works again, fix stream_read command line option
1075 - fix pic_add, hist
1076 - fix mysql dbtool startup in case no database exists
1077 - many small fixes and cleanups
1078
1079 ---------------------------------------
1080 0.1.3: (2004-12-10) "vanishing inertia"
1081 ---------------------------------------
1082
1083 Starting from this release, the database tools are integrated in the
1084 server binary. This decreases server startup time, reduces code size
1085 and speeds up database commands. However, the layout of the underlying
1086 mysql database changed only slightly and 0.1.3 should be backwards
1087 compatible in that respect.
1088
1089 Visible changes:
1090
1091 - If mysql is not detected at compile time, or fails to init
1092 at runtime, fall back to the dopey database tool which should
1093 always work.
1094 - para_dbtool and dbtool.conf are gone. All mysql specific
1095 options are read from server.conf and are prefixed by 'mysql_'.
1096 - new command: cdt (change database tool)
1097 - new command line option: dbtool (choose startup database tool)
1098 - The name of current stream is now stored in the database,
1099 so paraslash remembers its current stream when restarted.
1100 - new command: csp (change stream and play)
1101 - para_gui also reports current database tool and server uptime
1102
1103 -------------------------------------------
1104 0.1.2: (2004-11-28) "spherical fluctuation"
1105 -------------------------------------------
1106
1107 Point release before the big dbtool changes go in.
1108
1109 - dbtool: rename ca to cam (copy all meta data). It now also
1110 copies numplayed and lastplayed time as well as the picture
1111 id.
1112 - fix endless-loop-bug caused by mp3 files with invalid header
1113
1114 -----------------------------------------
1115 0.1.1: (2004-11-05) "floating atmosphere"
1116 -----------------------------------------
1117

1133
1134 -----------------------------------------
1135 0.0.99: (2004-07-25) "harmonic deviation"
1136 -----------------------------------------
1137
1138 - rename projectname from icc to paraslash (play, archive, rate
1139 and stream large audio sets happily)
1140 - paraslash is no longer restricted to one particular audio
1141 streaming software
1142 - new dbtool commands (stradd, strq, strdel) for easy stream
1143 managment w/o configuration file. That obsoletes stream_defs
1144 file/config option for dbtool.
1145 - picadd accepts jpeg data from stdin
1146 - new server commands: ps (select previous stream), sc (song change)
1147 - new default pictures for sdl_gui
1148 - gui: new key_map option for binding commands and internal
1149 functions to arbitrary keys, nice help screen, rip out
1150 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1151 show silly logo on startup
1152 - new executables: para_fade for fading volume, para_dbadm for
1153 manipulating attributes
1154 - cdb adds _all_ tables to mysql database

1162
1163 - kick icecast in favour of poc. That removes some races and reduces
1164 core code considerably.
1165 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags

1167 - gui can start decoder (see config options). Further new gui
1168 commands: refresh (^L), jmp (F1-F10)
1169 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1170 terminates gui. This fixes dead instances consuming memory
1171 continuously.
1172 - new dbtool command: verb for sending verbatim sql queries.
1173 - fix pid_list races (by removing pid_list)
1174 - codename funnies
