5 0.5.6 (2016-07-10) "cascading gradient"
6 ---------------------------------------
8 The highlight of this release is the new -m flag for para_afh which
9 lets it modify the meta tags of the given audio file(s). This feature
10 is supported for all audio formats. Many small cleanups and bug fixes
11 not mentioned here have accumulated and are also part of the release.
13 - para_afh learned to modify meta tags of mp3 wma ogg spx
15 - afs commands propagate error codes to the client.
16 - The check command now also checks the attribute table for
18 - New -v flag for the version command (print verbose version string)
19 - New option --priority for para_server and para_audiod.
20 - New mood methods: image_id and lyrics_id.
21 - The manual and this NEWS file have been converted to markdown.
22 - Support for the compile-time loglevel feature has been removed.
23 - Cleanup of the wma decoder and bitstream code.
24 - Improved wide-character support and fixes related to signal handling.
25 - para_gui no longer reports 100% playing time at the stream start.

32 0.5.5 (2015-09-20) "magnetic momentum"
33 --------------------------------------
35 Many new features and a lot of other improvements.
37 - On Linux systems, local sockets are now created in the
38 abstract name space by default. This allows to get rid of
39 the socket specials in /var/paraslash.
40 - The --user-allow option of para_audiod now accepts also
41 usernames rather than only user IDs.
42 - New autoconf macros to avoid duplication in configure.ac.
43 - Status items (as shown by para_gui) are updated correctly
44 when the meta information of the current audio changes.
45 - para_server and para_audiod no longer refuse to start in
46 the background if no log file is given. Instead, all log
47 messages go to /dev/null in this case.
49 - New syntax for the -l and -s options of the ls command.
50 These options should now be specified as -l=v rather than
51 -lv, for example. The old syntax still works, but support
52 will be dropped in v0.6.0.

79 ---------------------------------------------
80 0.5.3 (2014-08-01) "symbolic synchronization"
81 ---------------------------------------------
83 Not many new features, but lots of fixes and usability improvements.
85 - para_gui has been converted to use the paraslash scheduler.
86 - Various alsa-related fixes, mostly for the raspberry pi.
87 - Many scheduler improvements and cleanups.
88 - The test suite has been extended to include sanity checks
89 for the generated man pages.
90 - ao_writer fixes. This writer was in a quite bad shape. Many
91 serious bugs have been fixed.
92 - new audiod command: version.
93 - Minor improvements to the bitstream API.
94 - The cpsi command now prints a meaningful error message if
95 none of the given patterns matched any audio file.

101 ----------------------------------------
102 0.5.2 (2014-04-11) "orthogonal interior"
103 ----------------------------------------
105 The new sync filter, the AES_CTR128 stream cipher and the overhauled
106 network code are the highlights of this release. It also includes a
107 fair number of smaller fixes and improvements not mentioned here.
109 - The new sync filter synchronizes playback between multiple
111 - Connections between para_server and para_client are now
112 encrypted by means of AES rather than RC4 if both sides
113 support it. RC4 is still available as a fallback. This
114 feature is fully transparent, i.e. no command line options
115 are necessary, and a client linked against openssl can
116 speak with a server linked against libgcrypt and vice versa.
117 - Major cleanup of the networking subsystem.
118 - Improvements to para_fade: the new set mode, multi-channel
119 initial volumes, better error logging.
120 - The man pages of para_audiod, para_filter, para_recv, and
121 para_write contain the relevant options for receivers, filters,
122 writers. This broke in 0.5.0.
123 - ogg/vorbis latency improvements.
124 - Improved user manual.
125 - Minor fixes to avoid clang warnings.

131 ------------------------------------------
132 0.5.1 (2013-12-20) "temporary implication"
133 ------------------------------------------
135 Lots of fixes and improvements all over the place, and a major overhaul
138 - Audiod improvements and fixes.
139 - Buffer tree robustness improvements.
140 - Cleanup of the mood subsystem.
141 - Fixes and cleanups for the flac decoder.
142 - Latency improvements for the ogg/opus decoder.
143 - Crypto support is now optional. On systems without
144 openssl/gcrypt, the build succeeds but para_server,
145 para_audiod, para_client won't be built.
146 - The build system now works for cross-compile setups.
147 - The dependency tree has been flattened, which speeds up
148 builds and avoids to recreate the man pages on every change.
149 - The error code helper has been rewritten from perl to C,
150 which further improves build time.
151 - Many small bugs in the build system have been identified

159 0.5.0 (2013-08-23) "invertible validity"
160 ----------------------------------------
162 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
164 - The sideband compatibility code has been removed, hence
165 sideband connections (introduced in 0.4.11) are now mandatory.
166 - Addblob commands can produce output.
167 - The stat command no longer sends garbage when para_server was
168 compiled against libgcrypt.
169 - Dependencies for gengetopt files are computed automatically.
170 This eliminates a constant source of build bugs.
171 - The setatt command now accepts file name patterns rather than only
173 - overview.pdf is now based on dia, a simple diagram creation program.
174 The new version is much more detailed and contains descriptions of
175 the various programs of the paraslash package.
176 - The separator of all multi-word options has been changed from
177 underscore to dash. For example --log_color becomes --log-color.
178 - Overhauled web pages and the new logo.

184 --------------------------------------
185 0.4.13 (2013-07-29) "spectral gravity"
186 --------------------------------------
188 One more 0.4.x release before the API-breaking changes for 0.5.0 go
189 in. The main features of this release are the ogg/opus audio format,
190 and UTF-8 support, but it includes also tons of other improvements
191 and fixes all over the place.
193 - New audio format: ogg/opus.
194 - UTF8 support for para_gui and the mp3 audio format handler.
195 - Scheduler improvements and fixes.
196 - The obsolete gettimeofday() function has been replaced
197 by clock_gettime() on systems which support it.
198 - Speed and usability improvements for para_gui.
199 - para_client now restores the fd flags of stdin and stdout
201 - Improved manual pages.
202 - Consistent version strings for all executables.
203 - Reduced dependencies on generated files result in fewer
204 recompilations on changes.
205 - Performance improvements for the compress filter.
206 - Improved downloads web page.
208 -----------------------------------------
209 0.4.12 (2012-12-20) "volatile relativity"
210 -----------------------------------------
211 The new command line player, the resample filter, ALSA support for
212 para_fade, and the improved build system are the highlights of this
213 release which probably marks the end of the 0.4.x series.
215 - The afh receiver and the para_play executable.
216 - The resample filter: A sample rate converter based on
218 - The "versions" directory has been removed from the master
219 branch. The tarballs of the old releases are now available
220 in the new "releases" branch.
221 - Overhaul of the build system: All generated files are now
222 written to the "build" directory.
223 - The modular mixer API and the alsa mixer.
224 - Minor fixes for the osx writer.
226 --------------------------------------
227 0.4.11 (2012-07-20) "mutual diversity"
228 --------------------------------------
230 The major feature in this release is the new sideband API for
231 client-server communication. This API will be used exclusively starting
232 with 0.5.0, which breaks backward compatibility but allows to get rid
233 of quite some compatibility code. Other noteworthy changes include
234 decoder latency improvements and a long-standing bug fix for the
237 - Sideband connections: If both para_server and para_client
238 support this feature, data is sent as a multiplexed stream.
239 - The --no_default_filters option of para_filter has been
241 - Several fixes and latency improvements to various decoders.
242 - The ALSA writer now limits the prebuffer time to 500ms.
243 - Documentation improvements.
244 - Overhaul of the command_util.sh script.
245 - Fixes for some minor problems found by the clang analyzer.
246 - Compiles (almost) without warnings on gcc-3.
247 - Robustness improvements of the buffer tree code.
249 ------------------------------------------
250 0.4.10 (2012-03-30) "heterogeneous vacuum"
251 ------------------------------------------
253 Nothing earth-shaking in this release, but quite a few usability
254 improvements and the usual mix of cleanups and fixes.
256 - The --no_default_filters option of para_filter has been
257 deprecated. It still works but has no effect and will be
258 removed in the next version.
259 - para_gui now prints also the stderr output of the executing
260 command in the bottom window.
261 - Cleanup and consolidation of the various wrappers for
262 write(), writev(), send() and friends.
263 - The obscure error messages on mmap() failures have been
264 replaced by meaningful messages. This affects mainly
266 - para_audioc: Cleanups and memory leak fixes.
267 - Test 0004-server no longer fails if para_server is not
269 - New configure options: --with-id3tag-{headers,libs}.
271 -------------------------------------
272 0.4.9 (2011-12-06) "hybrid causality"
273 -------------------------------------
275 Support for another audio format, interactive mode for para_client
276 and para_audiod and many small improvements/fixes all over the place.
278 - Support for flac, the free lossless audio codec.
279 - Fix for an endless loop in the mp3 decoder for certain
281 - When executed without specifying a command, para_client
282 and para_audioc start an interactive shell (requires
283 libreadline being installed). The interactive mode offers
284 full tab completion and command line history.
285 - autogen.sh now detects a distcc setup and adjusts the
286 parameter for the -j option of make accordingly.
287 - Shared memory areas are no longer restricted to 64K. We now
288 detect the maximal size of a shared memory area at runtime.
289 - cleanup of the internal uptime API.
290 - para_server prefaults the mmapped audio file to avoid
291 delays on slow media.
292 - A new test for the test-suite that exercises the
293 communication between para_server and para_audiod.
294 - The alsa writer eats up less CPU cycles when configured to
296 - Simplified and unified receiver code.
298 - Commands which print a list of matching audio files now
299 emit a meaningful error message if no audio file matched the
302 --------------------------------------
303 0.4.8 (2011-08-19) "nested assignment"
304 --------------------------------------
306 Gcrypt support, the overhauled osx writer and regex format specifiers
307 are the highlights of this release.
309 - support for libgcrypt as a drop-in replacement for openssl.
310 Run configure --enable-cryptolib=gcrypt to link against
311 libgcrypt. The two crypto implementations are compatible to
312 each other, i.e. a para_client executable linked against
313 gcrypt can connect to para_server linked against libssl
315 - Rewrite of the osx writer (output plugin for Mac OS).
316 - audiod: The format specifier for receivers, filters and
317 writers is now treated as a regular expression. This allows
318 to replace 5 lines in the config file (one for each audio
319 format) by one single line. See the manual for details.
320 - The \*.cmdline.[ch] files are no longer contained in the released
321 tarballs. This reduces the size of the tarballs but requires
322 gengetopt to build the tarball.
323 - Compiles cleanly also with llvm/clang.
324 - Corrupt mp3 files are handled more gracefully.
325 - The alsa writer uses poll fds instead of computing timeouts.
326 - Cleanup of the generic writer API.
327 - sched: Optimized zero timeouts.
328 - vss timeout cleanups.
329 - oggdec fixes and improvements.
331 --------------------------------------
332 0.4.7 (2011-06-01) "infinite rollback"
333 --------------------------------------
335 The new ao writer, support for ssh RSA keys and a couple of other
338 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
339 platforms through the libao audio library.
340 - Support for RSA keys generated with ssh-keygen.
341 - configure: improved options for ogg/vorbis/speex.
342 - The git version reported by --version always matches HEAD.
343 - The autogen script detects the number of processors and
344 runs a parallel make if possible.
345 - Major cleanup of the crypto API.
346 - Documentation updates.
348 ------------------------------------------
349 0.4.6 (2011-03-31) "deterministic entropy"
350 ------------------------------------------
352 Lots of ogg/vorbis improvements, the new test suite, enhancements
353 for para_gui and a fair amount of other bug fixes.
355 - For DCCP/OGG streams the audio file header is only sent once
356 at the beginning of the stream rather than periodically
357 every five seconds. This reduces network traffic and the
359 - The vorbis comment header is replaced by an empty dummy header
360 before the header is sent over the network. This also results in
361 less network traffic and smaller FEC groups.
362 - The new "test" make target allows to perform some sanity checks prior
363 to installing the package.
364 - ogg timing fixes and performance improvements
365 - Scheduler improvements
366 - Proper exit codes for para_write
367 - para_gui: New option --theme to select a startup theme. Several
368 other improvements and fixes.
369 - aacdec error message cleanups
370 - simplified color error handling
372 --------------------------------------------
373 0.4.5 (2010-12-17) "symmetric randomization"
374 --------------------------------------------
376 Bug fixes, internal cleanups and variable-sized FEC slices.
378 - Contains a fix for an invalid-free-bug in the ogg audio format
380 - Switching off the DCCP sender works again.
381 - para_audiod handles crashes of para_server more robustly.
382 - Internal scheduler and writer cleanups.
383 - Reduced latency due to variable-sized FEC slices.
384 - Improved documentation and error diagnostics.
385 - The build of para_server is now optional, allowing the build
386 to succeed in case libosl is not installed.
388 ------------------------------------------
389 0.4.4 (2010-08-06) "persistent regularity"
390 ------------------------------------------
392 Support for yet another audio format, para_write improvements and
395 - Support for the speex codec.
396 - Support for sample formats other than 16 bit little endian.
397 - error2.h is now created by a perl script which speeds up configure
399 - Fix a bug in the aac decoder which could lead to segfaults in
400 para_filter/para_audiod.
401 - Fixes for autoconf-2.66.
403 ----------------------------------------
404 0.4.3 (2010-07-05) "imaginary radiation"
405 ----------------------------------------
407 Many improvements for the DCCP and the UDP transport, the new user
408 manual and the usual mix of bug fixes and internal improvements.
410 - FEC support for the DCCP sender (Gerrit Renker). The new
411 --dccp_max_slice_size, --dccp_data_slices_per_group and
412 --dccp_slices_per_group options can be used to set the FEC
413 parameters for the DCCP transport.
414 - DNS lookups for UDP targets (Gerrit Renker).
415 - The new user manual replaces the README, README.afs, REQUIREMENTS
416 and INSTALL documents.
417 - Fix an end-of-file detection bug in the oggdec filter.
418 - The new nonblock API.
419 - Both options of the oggdec filter have been removed.
420 - New debug mode for the internal scheduler.
422 ------------------------------------------
423 0.4.2 (2010-04-23) "associative expansion"
424 ------------------------------------------
426 It's been some time since the last release, but finally here is
427 paraslash-0.4.2. The bulk of the changes comes from the new buffer
428 tree API, but there are changes all over the tree. Mainly performance
429 and usability improvements, but also quite some bug fixes.
431 - The new buffer tree API.
432 - DCCP: Support for CCID negotiation (Gerrit Renker).
433 - UDP robustness fixes.
434 - The --bufsize option for mp3dec is gone as it no longer makes sense
435 for the new buffer tree API.
436 - Fix audible buffer underruns for wma streams.
437 - The alsa writer no longer prints meaningless underrun durations.
438 - audiod: Defaults work also for udp streams. If no filter is
439 given for an audio format that is received via upd, fecdec is
440 automatically added as the first filter (along with the decoder).
442 ---------------------------------------
443 0.4.1 (2009-12-22) "concurrent horizon"
444 ---------------------------------------
446 Support for another audio format, minor feature enhancements and lots of bug
447 fixes. All fixes that have been accumulated in the maint branch (in particular
448 those mentionened in the 0.3.6 release notes) appear in this release as well.
451 - new afh option: --human to activate human-readable output.
452 - new server/audiod option: --log-timing to print timing information.
453 - build system improvements.
454 - source code documentation updates.
456 -------------------------------------
457 0.3.6 (2009-12-07) "cubic continuity"
458 -------------------------------------
460 Quite a few bugs have been found and fixed since 0.3.5, so here's
461 another 0.3.x release. No new features.
463 - Always check return value of malloc().
464 - ogg vorbis/FEC: Do not write garbage after the audio file header.
465 - exit if root privileges could not be dropped.
466 - FEC: Fix computation of extra slices.
467 - oss: Fix check for empty input buffer.
468 - Avoid buffer underruns due to filter chain output buffer constraints.
469 - server: Fix assignment of afs_pid.
470 - Don't panic if the afs database contains unknown audio formats.
471 - http/dccp: Do not send the audio file header twice.
472 - FEC: Timing improvements.
474 ----------------------------------------------
475 0.4.0 (2009-11-10) "simultaneous independence"
476 ----------------------------------------------
478 Two significant changes which require the new version number: The
479 improved authentication dialog and the fact that the database code
480 has been moved to a library, libosl. To use the new version, you have
481 to generate new RSA keys, see INSTALL for details. A shell script is
482 provided for conversion of the 0.3 database to the new 0.4 format.
484 - stronger crypto for client authentication
485 - the database code has been moved to a library
486 - improved status item handling
487 - cleanup of the build system
488 - The "-V" option now also prints the git version
489 - the new parser-friendly listing mode for the ls and stat commands
490 - mandatory rc4 encryption
491 - major audio format handler cleanups
492 - (id3,...) tags are no longer stored as a combined string in the database
493 - new mood methods: artist_matches, title_matches, comment_matches,
494 album_matches, year_maches, year.
496 --------------------------------------------
497 0.3.5 (2009-09-21) "symplectic separability"
498 --------------------------------------------
500 Full client support for \*BSD Unixes, complete re-write of the ogg
501 vorbis audio format handler, various improvements all over the place
502 and the usual mix of bugfixes. This release marks the end of the 0.3
503 series if no serious problems show up.
505 - the new oss writer (supported on \*BSD and Linux)
506 - rewrite of the ogg vorbis audio format handler. It's
507 recommended to replace the chunk tables of existing ogg
508 vorbis files in the afs database by re-adding these files
510 - support for netmask subsets (Gerrit Renker)
511 - the new prebuffer filter
512 - improved signal handling

521 -----------------------------------------
522 0.3.4 (2009-05-07) "elliptic inheritance"
523 -----------------------------------------
525 The new udp sender, forward error correction, colored logs and various
526 other improvements. As the udp sender does not depend on any special
527 libraries, it is built unconditionally.
529 - The udp sender replaces the ortp sender. The new code uses forward
530 error correction to protect against packet losses. Many thanks to
531 Gerrit Renker for providing ipv6 support.
532 - The default port for udp streaming now defaults to 8000, like
533 for the http and the dccp senders/receivers.
534 - Loglevels are now specified as symbolic names, e.g.
536 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
537 - para_server/para_audiod: Color support for log messages.
538 - new options for mp3dec: --ignore-crc, --bufsize
539 - new audiod option: --config-file.
540 - gengetopt cleanups.
541 - Improved help/man pages: The documentation of para_audiod,
542 para_recv, para_filter and para_write now also contains
543 all options of the available receivers/filters/writers. The
544 man page of para_fade contains a description of the different
546 - More source code documentation.
549 --------------------------------------------
550 0.3.3 (2008-12-01) "axiomatic perspectivity"
551 --------------------------------------------
553 Internal code cleanups, bug fixes, improved tag handling and the new
554 amplification filter.
556 - para_server uses the generic scheduling code.
557 - overhaul of the virtual streaming system.
558 - mp3: id3 version 2 support via libid3tag (optional)
559 - ogg: vorbis comment support.
560 - aac meta info support.
561 - mp3 audio format handler cleanups.
562 - new filter: "amp" to amplify the amplitude of the audio stream
563 - new status item/database entry: amplification. It is
564 used by the amp filter to pre-amplify the audio stream.
565 - fix a close-without-open bug in para_write.
566 - fix a bug in com_init() which was introduced in 0.3.2.
567 - better error diagnostics for para_client.
569 -----------------------------------------
570 0.3.2 (2008-04-11) "probabilistic parity"
571 -----------------------------------------
573 The new para_afh executable, scheduling and documentation improvements.
575 - new ls option: -lc (list chunk table)
576 - new executable: para_afh, the stand-alone audio file handler tool
577 - afs commands can send output more than SHMMAX (32MB on Linux). This
578 also reduces the memory usage of commands that produce large amounts
580 - major scheduler and audiod cleanups.
581 - more detailed and much nicer man pages.
583 ---------------------------------------
584 0.3.1 (2008-02-23) "liquid interaction"
585 ---------------------------------------
587 A mix of cleanups, bug fixes, improvements, and some new features. No
588 significant changes to the new database (osl) code, which is generally
591 - Share some similar/duplicate code between the http and the
593 - Generic access control lists for paraslash senders.
594 - dccp sender: Access control lists, connection limiting and support
595 for the allow,deny,on,off,help sender commands.
596 - The default dccp port changed from 5001 to 8000 (suggested by
598 - para_server starts even if not all public keys could be loaded.
599 - Audiod performance improvements.
600 - fix a bug in the "off" command of the http sender.
601 - fix some fd and memory leaks.
602 - Update to gengetopt-2.22.
604 -------------------------------------
605 0.3.0 (2008-01-12) "solar saturation"
606 -------------------------------------
608 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
611 Usually one might expect lots of new features AND a big increase in size
612 for a major release like this.
614 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
615 ever. The decrease in size is mostly due to the removal of some
616 graphical tools (which were only quick hacks anyway). But also the
617 fact that the mysql code is gone cuts down the size a bit.
619 Being independent of mysql comes at a cost: The fact that paraslash
620 now contains its own database (the object storage layer, osl) increases
621 the (stripped) binary size of para_server by ~50K on i386.
623 - no more restrictions on unique basenames.
624 - independent of mysql: The new self-contained object
625 storage layer (osl) replaces the mysql database.
626 - New executable para_fsck: Check integrity of osl tables.
628 - Reliable audio file move/rename detection.
629 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
630 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
632 - the new osl-based audio file selector (afs) replaces the random,
633 the playlist and the mysql selector of paraslash-0.2.x.
634 - IPv6 support (thanks to Gerrit Renker).
635 - paraslash-0.2.x streams are now called "moods". Writing
636 0.3.x-mood definitions should be both easier and more
637 powerful than writing 0.2.x-stream definitions.
638 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
639 been removed. The world is a better place without them. However,
640 para_gui is still there.
641 - afs tracks audio file selection also in playlist mode.
642 - few easy-to-use afs commands replace the many not-so-easy-to-use
643 mysql commands (and are available also in playlist mode).
644 - Improved error subsystem.
645 - The earth-shaking new logo.
647 -----------------------------------------
648 0.2.17 (2007-11-20) "isotropic threshold"
649 -----------------------------------------
651 Mainly bugfixes and cleanups in this version which marks the end of
652 the 0.2.x series if no serious bugs show up after the release.
654 - mysql_selector: fix a locking bug.
655 - universal chunk queueing.
656 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
658 - be more carful wrt. signed vs. unsigned argument passing.
659 - cleanup error.h and fix some references to invalid error
661 - update to gengetopt-2.21.
662 - update to ortp-0.13.1.
663 - autoconf: extend checks for headers, library functions and
664 compiler characteristics.
665 - Fix streaming of large mp3 files.
666 - Fix an off-by-one bug in playlist handling.
668 --------------------------------------
669 0.2.16 (2007-04-05) "neural discharge"
670 --------------------------------------
672 The main change in this release is the major audio format handler
673 cleanup which removes some similar/duplicate code and makes it easier
674 to implement plugins for other audio formats. Of course, the usual mix
675 of other improvements/changes/bugfixes also made it into the release.
677 - simplified audio format handlers (most of the handling functions
678 were moved one layer up to the virtual streaming system).
679 - para_server uses mmap to read audio files
680 - repositioning of mp3 streams is much faster, in particular for
681 jumping near the end of large mp3 files.
682 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
684 - fix a bug in para_filter that caused decoding of aac files
685 to start only after a few seconds.
686 - fix osx_writer hangs
687 - simplified dccp code (thanks to Gerrit Renker)
688 - the compress filter works also on big endian systems (ppc)
690 -----------------------------------------
691 0.2.15 (2007-02-16) "inductive resonance"
692 -----------------------------------------
694 Minor improvements, more documentation and a bunch of bug fixes.
696 - para_server: The server.users file is only read once on server
697 startup rather than for each connection
698 - mp3dec: Fix decoding of corrupt mp3 files
699 - afs (audio file sender) is now called vss (virtual streaming
700 system). Consequently, the permission flags specified in
701 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
702 become VSS_READ and VSS_WRITE respectively.
703 - para_audiod/para_filter: Fix a bug that caused the last chunk
704 of audio data not being written under certain circumstances
705 - audiod: compute the difference of server time and local time
707 - para_server/para_audiod: Fix some memory leaks
708 - documentation improvements
709 - configure.ac: fix checks for para_krell
712 -------------------------------------------
713 0.2.14 (2006-10-15) "transient singularity"
714 -------------------------------------------
716 The only major enhancement of this version is the osx writer which completes
717 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
718 until now for reasons beyond the scope of this changelog entry.
720 - new output plugin for Mac Os: the osx writer
721 - rename configure command line options from --enable-xxx-headers to
722 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
723 - configure: new command line options: --with-mad-headers,
724 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
725 - some robustness fixes
726 - dymamic audio format recognition for audiod
727 - para_server: new command line option: --autoplay_delay
728 - para_audiod: new command line option: --clock_diff_count
730 ---------------------------------------
731 0.2.13 (2006-07-14) "sonic convolution"
732 ---------------------------------------
734 A bunch of new features and core changes.
736 - the new paraslash scheduler, short and sweet.
737 - Support for m4a/mp4 files via the new aac audio format
738 handler/filter (requires libfaad).
739 - each writer has its own command line parser, just like
740 para_recv and para_filter.
741 - para_client and para_audioc use the error subsystem
742 - writers are integrated in para_audiod (currently linux-only)
743 - para_client is integrated in para_audiod
744 - random/playlist selector: improved info strings
745 - new audiod commands: tasks, kill
746 - update to libortp-0.10.1
747 - para_fade: wake time defaults to 8 hours from now
748 - update to autoconf-2.60
750 ------------------------------------------
751 0.2.12 (2006-05-12) "oriented abstraction"
752 ------------------------------------------
754 Many user-visible changes in this release and lots of new
757 - the new optional dccp sender/receiver. It uses the datagram
758 congestion control protocol. You'll need a fairly new kernel
760 - paraslash works on Mac OS X (thanks to Gerd Becker)
761 - para_play renamed to para_write
762 - modular output plugin design (writers) for para_write
763 - new file_writer output plugin for para_write
764 - compress filter speed improvements
765 - update to libortp-0.9.1
766 - update to gengetopt-2.17rc
767 - para_client no longer depends on libreadline (as the
768 code for the interactive mode was removed).
769 - gcc-2-95 is no longer a supported compiler. It may still
770 work, but it gets no more testing.
771 - the tarball no longer contains the screenshot images which
772 reduces its size quite a bit.
773 - configure: new command line options: --enable-mysql-headers
774 and --enable-mysql-libs
776 ------------------------------------
777 0.2.11 (2006-03-11) "atomic duality"
778 ------------------------------------
780 Here it is, the first paraslash release developed with git. There
781 are fairly many user-visible changes in this release. As two out of
782 the three "database tools" of paraslash don't use a database at all,
783 they are now called "audio file selectors" instead.
785 - the cdt command (change database tool) becomes chs (change
787 - no more colon separators: The syntax of some options of
788 para_audiod and para_filter have changed. Use --help for
789 more info (and some examples).
790 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
791 - switch from cvs to git (should've done that earlier)
792 - the new ipc subsystem
793 - new audio file selector: playlist
794 - para_server: the dopey selector is now called "random",
795 and is the default selector. Use the --selector option to
796 choose another selector at startup, or the chs command to
797 change the selector at runtime.
798 - X86_64 fixes (thanks to Steffen Klassert)
801 --------------------------------------
802 0.2.10 (2006-02-17) "cyclic attractor"
803 --------------------------------------
805 Huge documentation update, a scrollable window for para_gui, ortp
806 improvements, and of course many small fixes not mentioned here.
807 The diffstat below is rather misleading as most insertions are due
808 to the new source documentation.
811 - para_server also uses the new error subsystem
812 - lots of new documentation (UTSL)
814 - keysyms for cursor keys and for next/previous page keys
815 - scrollable output window
816 - new internal commands: scroll up/down, page up/down
817 - fix color of command output.
818 - ortp: the --chunk_time and --header flags are no longer needed
819 for para_recv/para_audiod as this information is now encoded in
820 each rtp packet sent by para_server.
822 -------------------------------------------
823 0.2.9 (2006-01-24) "progressive turbulence"
824 -------------------------------------------
826 Internal audiod receivers/filters, the new error subsystem and
827 a lot of small improvements.
829 - para_recv and para_filter are integrated into the para_audiod
830 binary, i.e. audiod no longer spawns a new process for
831 each receiver/filter. As para_recv and para_filter might be
832 useful as standalone programs, they still get built (linked
833 against the same object files that are also used for audiod).
834 - further ortp timing improvements should reduce the CPU usage
835 of the ortp receiver.
836 - improved audio grabbing. The 'grab' command of para_audiod
837 has its own set of command line options. Read the output of
838 "para_audioc help grab" for more info.
839 - oggdec: configurable input prebuffer size.
840 - the new error subsystem gives better error diagnostics
841 and reduces code size.
843 -----------------------------------------
844 0.2.8 (2006-01-02) "dynamic accumulation"
845 -----------------------------------------
847 The new modular filter design and the para_play-hangs bugfix.
849 - new executable: para_filter. It combines para_mp3dec,
850 para_oggdec and para_compress. It also adds a further filter
851 type, wav, that just inserts a wave header at the desired point
852 of the filter chain. All 'piping' is done in-memory (i.e. no
853 read/write operations are used).
854 - para_play: fix a stupid bug that caused it to hang under
855 certain circumstances.
857 -------------------------------------------
858 0.2.7 (2006-12-27) "transparent invariance"
859 -------------------------------------------
861 Not many user-visible changes but a fair amount of internal improvements.
863 - The http sender buffers data if it can not be sent
864 out immediately (because the socket is not writable). This
865 should prevent para_server from shutting down the connection
866 too early on a loaded network.
867 - para_play also prebuffers data if it is told to start at a
868 future time by the --start_time option.
869 - The return of para_recv: It combines para_ortp_recv and
870 para_http_recv. Use the --receiver option to switch between
871 the two. para_recv builds without libortp, but contains
872 only the http receiver in this case.
873 - update to ortp 0.8.1. As this ortp release contains incompatible
874 changes, para_recv-0.2.7 won't link against older ortp libs.
875 - improved ortp timings.
876 - use of gcc-extensions that #define away for non-gcc and
879 -------------------------------------------
880 0.2.6 (2005-10-29) "recursive compensation"
881 -------------------------------------------
883 Transparent session encryption (uses openssl's Alleged RC4 cipher),
884 the internal find command and several other improvements and cleanups.
886 - Encrypt the session if encryption is requested by the client
887 (default for para_client 0.2.6). This is backwards
888 compatible, so older clients can still connect to para_server
889 0.2.6. Use the new client option --plain to request an
890 uncrypted session (off by default, must be set to on in
891 order to connect to para_server 0.2.x with 0 <= x <= 5).
892 - para_server uses an internal function to locate audio files
893 rather than calling find(1). The server option
894 --mysql_audio_file_dir replaces --mysql_find_cmd.
895 - documentation update
897 - header file cleanup
898 - para_client code cleanup
899 - para_gui: faster display of output of display commands
901 ------------------------------------------
902 0.2.5 (2005-10-13) "aggressive resolution"
903 ------------------------------------------
905 This release adds internal senders, i.e. no more external programs are
906 spawned for sending out the audio data. There are two different senders
907 available: The http sender and the ortp sender (former para_send which
908 is no longer needed).
910 The new sender code has a plugin-like design so it can be easily
911 extended should there be be any future need for supporting another
912 network streaming protocol. All senders are completely independent of
913 each other. In particular, the http and the ortp sender can operate
916 - new server command: sender to control senders at runtime.
917 Read the output of "para_server -h" and "para_client help
918 sender" for more information.
919 - para_recv renamed to para_ortp_recv
920 - new executable: para_http_recv, a simple command line
922 - major afs/mp3/ogg code simplifications due to internal
924 - ogg timing improvements
925 - fix several minor memory leaks (found by valgrind)
926 - empty stream definitions work again
927 - com_ne(): ignore errors on remove
928 - audiod: fix segfault on server restart
930 ---------------------------------------
931 0.2.4 (2005-09-21) "toxic anticipation"
932 ---------------------------------------
934 Several small improvements, fixes and the new grab command.
937 - new command: "grab" to grab the output of the stream reader
938 or any filters. Read the output of "para_audioc help grab"
939 for more information.
942 - audioc: new command line option: --bufsize to specify a
943 buffer size different from the default size 8192.
944 - improved error diagnostics for para_play.
945 - new configure option: --enable-ssldir so search for openssl in
947 - sdl_gui: Make it look nice again for 1024x768
948 - server: report total size of memory allocated with sbrk by malloc,
949 new command line option: --announce_time
951 -----------------------------------------
952 0.2.3 (2005-09-01) "hydrophilic movement"
953 -----------------------------------------
955 Two new executables and major feature enhancements.
957 - audiod filters: It is now possible to specify arbitrary many
958 (including none) filters for each supported audio
959 format. This can be used e.g. for normalizing volume,
960 transforming or grabbing the audio stream, or for using
961 visualizers. Read the output of "para_audiod -h" for the
962 syntax of the new --filter_cmd option.
963 - new executable: para_play, a tiny alsa player. It
964 can play wave files or raw pcm (16 bit little endian)
966 - new executable: para_compress, a dynamic range compressor
967 intended to keep audio output at a consistent volume. Derived
968 from [AudioCompress](http://trikuare.cx/code/AudioCompress.html).
969 - audiod: New option: --stream_delay. This can be used in
970 a local network to syncronize the audio output of all
971 clients that play the same stream.
973 ------------------------------------------
974 0.2.2 (2005-08-19) "tangential excitation"
975 ------------------------------------------
977 Mostly internal changes in this release, but also some new commands
978 for the mysql database tool.
980 - cleanup exec.c, fix para_exec bug
981 - compile time loglevel (log messages below the given level
982 won't be compiled in, which reduces the size of the
984 - new log macros that shorten the size of the source code.
985 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
986 to send only zeros. With this workaround, para_audioc works
988 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
989 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
990 (new entry), "snp" (set numplayed). Read the manual for more
993 ---------------------------------------
994 0.2.1 (2005-08-15) "surreal experience"
995 ---------------------------------------
997 Here comes paraslash-0.2.1. It contains a couple of new features and,
998 surprise, only minor bug fixes.
1000 - kill noisy mp3 debug message
1001 - cleanup of the build system
1002 - para_server and para_client directly use the crypto routines
1003 of the openssl library rather than invoking the openssl command
1005 - server/audiod: new option --user to switch to the given user
1006 when invoked as root. Read the output of "para_server -h" for
1008 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
1009 status. Default: "para_audioc stat"
1010 - sdl_gui: new option --pic_cmd to be used to download the picture.
1011 Default: "para_client pic"
1012 - audiod: 5 slots ought to be enough for everybody
1013 - audiod: new status item: Uptime, kill hup command
1015 ------------------------------------------
1016 0.2.0 (2005-08-06) "distributed diffusion"
1017 ------------------------------------------
1019 After several month of increased development activity, paraslash-0.2.0
1020 has arrived. It contains many new features and is much more
1021 self-contained than the old 0.1.x series. Enjoy!
1023 - para_server: fix hang on song change and crash on sighup.
1024 Speed up mysql queries. The DIR_LIKE macro is gone.
1025 - new executables: para_audiod, the local audio daemon that
1026 starts playback (uses SCM_CREDENTIALS socket magic) and
1027 para_audioc, the corresponding client.
1028 - new executables: para_mp3dec/para_oggdec, two really teensy
1029 decoders. para_mp3dec is based on libmad, para_oggdec requires
1031 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
1032 they are now called para_send and para_recv respectively.
1033 - documentation updates
1034 - para_gui is themable. For now there is the default theme that
1035 looks as before and the simple theme: blue and easy.
1036 - gui: audio streaming is now handled by audiod. Time display shows
1037 playback time rather than streaming time
1038 - slider: update to libzmw-0.2.0
1039 - para_krell: fix crash on server shutdown
1040 - switch from gzip to bzip2
1042 ----------------------------------------
1043 0.1.7 (2005-04-18) "melting penetration"
1044 ----------------------------------------
1046 The main change in this release is clearly the oggvorbis rewrite,
1047 but there are also lots of smaller changes. If you intend to use both
1048 the mp3 and the ogg plugin, it is recommended to use software mixing,
1049 e.g. the dmix plugin which is provided by ALSA.
1051 - new executables: para_ovsend and para_ovrecv for sending/receiving
1052 oggvorbis files via rtp. Requires the open rtp library. Get it at
1053 http://www.linphone.org/ortp/
1054 - rewrite of the ogg_vorbis core code
1055 - configure detects libzmw and, if detected, includes
1056 para_slider to the list of binaries to be built by make
1057 - server stream writers read from their associated fifo rather
1059 - slider: two new sliders, lastplayed and numplayed
1060 - fix nasty double free bug which caused random segfaults in case of
1061 mp3 files with invalid header information
1062 - gui: new command line option: --stream_timeout=seconds to
1063 deactivate a slot if it is idle for that many seconds (default=`5')
1066 ---------------------------------------
1067 0.1.6 (2005-03-05) "asymptotic balance"
1068 ---------------------------------------
1070 Only little user-visible changes in this release. Mainly bugfixes and
1071 core code cleanup. This is probably the most stable version ever if you
1074 - fix several memory leaks
1075 - rename default name of mysql database from "music" to "paraslash".
1076 Use para_server's --mysql_database option if you do not want to
1077 rename your old database.
1078 - rework ogg vorbis code
1079 - make update command work on mysql servers with LOCAL_INFILE
1081 - gui: improved stream I/O (slots)
1082 - simplified audio format API
1083 - para_pob_ogg is gone
1085 ------------------------------------
1086 0.1.5 (2004-12-31) "opaque eternity"
1087 ------------------------------------
1089 Let's slide gently into the new year.
1091 - new: para_slider (not built automatically, type "make
1092 para_slider" to build). A toy for those who always felt that
1093 creating stream definitions is difficult. See screenshots,
1094 README and FEATURES for more info.
1095 - improved signal handling. Fixes server segfault on SIGHUP
1096 for linux kernels newer than Aug 24 2004 and makes para_gui
1098 - reload database tool on SIGHUP
1099 - improved help message for sl
1100 - do not log "broken pipe" messages as errors. They are
1102 - fix wrong error message on permission errors
1104 -----------------------------------------
1105 0.1.4 (2004-12-19) "tunneling transition"
1106 -----------------------------------------
1108 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1109 Hopefully, most of them got wiped out with this release. Some
1110 enhancements went also in.
1112 - improved error diagnostics for all commands
1113 - stradd/picadd: overwrite previous contents if entry already
1114 exists, rather than returning errors
1115 - stradd: use current stream if invoked without args
1116 - faster (and hopefully more stable) ogg-vorbis handling
1117 - para_krell: reap children to avoid zombie-flooding in case
1118 no server is running
1119 - si: report also server pid
1120 - server: don't busy-loop if dbtool reports only invalid files.
1121 - gui: CTRL+C works again, fix stream_read command line option
1123 - fix mysql dbtool startup in case no database exists
1124 - many small fixes and cleanups
1126 ---------------------------------------
1127 0.1.3: (2004-12-10) "vanishing inertia"
1128 ---------------------------------------
1130 Starting from this release, the database tools are integrated in the
1131 server binary. This decreases server startup time, reduces code size
1132 and speeds up database commands. However, the layout of the underlying
1133 mysql database changed only slightly and 0.1.3 should be backwards
1134 compatible in that respect.
1138 - If mysql is not detected at compile time, or fails to init
1139 at runtime, fall back to the dopey database tool which should
1141 - para_dbtool and dbtool.conf are gone. All mysql specific
1142 options are read from server.conf and are prefixed by 'mysql_'.
1143 - new command: cdt (change database tool)
1144 - new command line option: dbtool (choose startup database tool)
1145 - The name of current stream is now stored in the database,
1146 so paraslash remembers its current stream when restarted.
1147 - new command: csp (change stream and play)
