15 ---------------------------------------
16 0.5.6 (2016-07-10) "cascading gradient"
17 ---------------------------------------
19 The highlight of this release is the new -m flag for para_afh which
20 lets it modify the meta tags of the given audio file(s). This feature
21 is supported for all audio formats. Many small cleanups and bug fixes
22 not mentioned here have accumulated and are also part of the release.
24 - para_afh learned to modify meta tags of mp3 wma ogg spx
26 - afs commands propagate error codes to the client.
27 - The check command now also checks the attribute table for
29 - New -v flag for the version command (print verbose version string)
30 - New option --priority for para_server and para_audiod.
31 - New mood methods: image_id and lyrics_id.
32 - The manual and this NEWS file have been converted to markdown.
33 - Support for the compile-time loglevel feature has been removed.
34 - Cleanup of the wma decoder and bitstream code.
35 - Improved wide-character support and fixes related to signal handling.
36 - para_gui no longer reports 100% playing time at the stream start.

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

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

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

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

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

195 --------------------------------------
196 0.4.13 (2013-07-29) "spectral gravity"
197 --------------------------------------
199 One more 0.4.x release before the API-breaking changes for 0.5.0 go
200 in. The main features of this release are the ogg/opus audio format,
201 and UTF-8 support, but it includes also tons of other improvements
202 and fixes all over the place.
204 - New audio format: ogg/opus.
205 - UTF8 support for para_gui and the mp3 audio format handler.
206 - Scheduler improvements and fixes.
207 - The obsolete gettimeofday() function has been replaced
208 by clock_gettime() on systems which support it.
209 - Speed and usability improvements for para_gui.
210 - para_client now restores the fd flags of stdin and stdout
212 - Improved manual pages.
213 - Consistent version strings for all executables.
214 - Reduced dependencies on generated files result in fewer
215 recompilations on changes.
216 - Performance improvements for the compress filter.
217 - Improved downloads web page.
219 -----------------------------------------
220 0.4.12 (2012-12-20) "volatile relativity"
221 -----------------------------------------
222 The new command line player, the resample filter, ALSA support for
223 para_fade, and the improved build system are the highlights of this
224 release which probably marks the end of the 0.4.x series.
226 - The afh receiver and the para_play executable.
227 - The resample filter: A sample rate converter based on
229 - The "versions" directory has been removed from the master
230 branch. The tarballs of the old releases are now available
231 in the new "releases" branch.
232 - Overhaul of the build system: All generated files are now
233 written to the "build" directory.
234 - The modular mixer API and the alsa mixer.
235 - Minor fixes for the osx writer.
237 --------------------------------------
238 0.4.11 (2012-07-20) "mutual diversity"
239 --------------------------------------
241 The major feature in this release is the new sideband API for
242 client-server communication. This API will be used exclusively starting
243 with 0.5.0, which breaks backward compatibility but allows to get rid
244 of quite some compatibility code. Other noteworthy changes include
245 decoder latency improvements and a long-standing bug fix for the
248 - Sideband connections: If both para_server and para_client
249 support this feature, data is sent as a multiplexed stream.
250 - The --no_default_filters option of para_filter has been
252 - Several fixes and latency improvements to various decoders.
253 - The ALSA writer now limits the prebuffer time to 500ms.
254 - Documentation improvements.
255 - Overhaul of the command_util.sh script.
256 - Fixes for some minor problems found by the clang analyzer.
257 - Compiles (almost) without warnings on gcc-3.
258 - Robustness improvements of the buffer tree code.
260 ------------------------------------------
261 0.4.10 (2012-03-30) "heterogeneous vacuum"
262 ------------------------------------------
264 Nothing earth-shaking in this release, but quite a few usability
265 improvements and the usual mix of cleanups and fixes.
267 - The --no_default_filters option of para_filter has been
268 deprecated. It still works but has no effect and will be
269 removed in the next version.
270 - para_gui now prints also the stderr output of the executing
271 command in the bottom window.
272 - Cleanup and consolidation of the various wrappers for
273 write(), writev(), send() and friends.
274 - The obscure error messages on mmap() failures have been
275 replaced by meaningful messages. This affects mainly
277 - para_audioc: Cleanups and memory leak fixes.
278 - Test 0004-server no longer fails if para_server is not
280 - New configure options: --with-id3tag-{headers,libs}.
282 -------------------------------------
283 0.4.9 (2011-12-06) "hybrid causality"
284 -------------------------------------
286 Support for another audio format, interactive mode for para_client
287 and para_audiod and many small improvements/fixes all over the place.
289 - Support for flac, the free lossless audio codec.
290 - Fix for an endless loop in the mp3 decoder for certain
292 - When executed without specifying a command, para_client
293 and para_audioc start an interactive shell (requires
294 libreadline being installed). The interactive mode offers
295 full tab completion and command line history.
296 - autogen.sh now detects a distcc setup and adjusts the
297 parameter for the -j option of make accordingly.
298 - Shared memory areas are no longer restricted to 64K. We now
299 detect the maximal size of a shared memory area at runtime.
300 - cleanup of the internal uptime API.
301 - para_server prefaults the mmapped audio file to avoid
302 delays on slow media.
303 - A new test for the test-suite that exercises the
304 communication between para_server and para_audiod.
305 - The alsa writer eats up less CPU cycles when configured to
307 - Simplified and unified receiver code.
309 - Commands which print a list of matching audio files now
310 emit a meaningful error message if no audio file matched the
313 --------------------------------------
314 0.4.8 (2011-08-19) "nested assignment"
315 --------------------------------------
317 Gcrypt support, the overhauled osx writer and regex format specifiers
318 are the highlights of this release.
320 - support for libgcrypt as a drop-in replacement for openssl.
321 Run configure --enable-cryptolib=gcrypt to link against
322 libgcrypt. The two crypto implementations are compatible to
323 each other, i.e. a para_client executable linked against
324 gcrypt can connect to para_server linked against libssl
326 - Rewrite of the osx writer (output plugin for Mac OS).
327 - audiod: The format specifier for receivers, filters and
328 writers is now treated as a regular expression. This allows
329 to replace 5 lines in the config file (one for each audio
330 format) by one single line. See the manual for details.
331 - The \*.cmdline.[ch] files are no longer contained in the released
332 tarballs. This reduces the size of the tarballs but requires
333 gengetopt to build the tarball.
334 - Compiles cleanly also with llvm/clang.
335 - Corrupt mp3 files are handled more gracefully.
336 - The alsa writer uses poll fds instead of computing timeouts.
337 - Cleanup of the generic writer API.
338 - sched: Optimized zero timeouts.
339 - vss timeout cleanups.
340 - oggdec fixes and improvements.
342 --------------------------------------
343 0.4.7 (2011-06-01) "infinite rollback"
344 --------------------------------------
346 The new ao writer, support for ssh RSA keys and a couple of other
349 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
350 platforms through the libao audio library.
351 - Support for RSA keys generated with ssh-keygen.
352 - configure: improved options for ogg/vorbis/speex.
353 - The git version reported by --version always matches HEAD.
354 - The autogen script detects the number of processors and
355 runs a parallel make if possible.
356 - Major cleanup of the crypto API.
357 - Documentation updates.
359 ------------------------------------------
360 0.4.6 (2011-03-31) "deterministic entropy"
361 ------------------------------------------
363 Lots of ogg/vorbis improvements, the new test suite, enhancements
364 for para_gui and a fair amount of other bug fixes.
366 - For DCCP/OGG streams the audio file header is only sent once
367 at the beginning of the stream rather than periodically
368 every five seconds. This reduces network traffic and the
370 - The vorbis comment header is replaced by an empty dummy header
371 before the header is sent over the network. This also results in
372 less network traffic and smaller FEC groups.
373 - The new "test" make target allows to perform some sanity checks prior
374 to installing the package.
375 - ogg timing fixes and performance improvements
376 - Scheduler improvements
377 - Proper exit codes for para_write
378 - para_gui: New option --theme to select a startup theme. Several
379 other improvements and fixes.
380 - aacdec error message cleanups
381 - simplified color error handling
383 --------------------------------------------
384 0.4.5 (2010-12-17) "symmetric randomization"
385 --------------------------------------------
387 Bug fixes, internal cleanups and variable-sized FEC slices.
389 - Contains a fix for an invalid-free-bug in the ogg audio format
391 - Switching off the DCCP sender works again.
392 - para_audiod handles crashes of para_server more robustly.
393 - Internal scheduler and writer cleanups.
394 - Reduced latency due to variable-sized FEC slices.
395 - Improved documentation and error diagnostics.
396 - The build of para_server is now optional, allowing the build
397 to succeed in case libosl is not installed.
399 ------------------------------------------
400 0.4.4 (2010-08-06) "persistent regularity"
401 ------------------------------------------
403 Support for yet another audio format, para_write improvements and
406 - Support for the speex codec.
407 - Support for sample formats other than 16 bit little endian.
408 - error2.h is now created by a perl script which speeds up configure
410 - Fix a bug in the aac decoder which could lead to segfaults in
411 para_filter/para_audiod.
412 - Fixes for autoconf-2.66.
414 ----------------------------------------
415 0.4.3 (2010-07-05) "imaginary radiation"
416 ----------------------------------------
418 Many improvements for the DCCP and the UDP transport, the new user
419 manual and the usual mix of bug fixes and internal improvements.
421 - FEC support for the DCCP sender (Gerrit Renker). The new
422 --dccp_max_slice_size, --dccp_data_slices_per_group and
423 --dccp_slices_per_group options can be used to set the FEC
424 parameters for the DCCP transport.
425 - DNS lookups for UDP targets (Gerrit Renker).
426 - The new user manual replaces the README, README.afs, REQUIREMENTS
427 and INSTALL documents.
428 - Fix an end-of-file detection bug in the oggdec filter.
429 - The new nonblock API.
430 - Both options of the oggdec filter have been removed.
431 - New debug mode for the internal scheduler.
433 ------------------------------------------
434 0.4.2 (2010-04-23) "associative expansion"
435 ------------------------------------------
437 It's been some time since the last release, but finally here is
438 paraslash-0.4.2. The bulk of the changes comes from the new buffer
439 tree API, but there are changes all over the tree. Mainly performance
440 and usability improvements, but also quite some bug fixes.
442 - The new buffer tree API.
443 - DCCP: Support for CCID negotiation (Gerrit Renker).
444 - UDP robustness fixes.
445 - The --bufsize option for mp3dec is gone as it no longer makes sense
446 for the new buffer tree API.
447 - Fix audible buffer underruns for wma streams.
448 - The alsa writer no longer prints meaningless underrun durations.
449 - audiod: Defaults work also for udp streams. If no filter is
450 given for an audio format that is received via upd, fecdec is
451 automatically added as the first filter (along with the decoder).
453 ---------------------------------------
454 0.4.1 (2009-12-22) "concurrent horizon"
455 ---------------------------------------
457 Support for another audio format, minor feature enhancements and lots of bug
458 fixes. All fixes that have been accumulated in the maint branch (in particular
459 those mentionened in the 0.3.6 release notes) appear in this release as well.
462 - new afh option: --human to activate human-readable output.
463 - new server/audiod option: --log-timing to print timing information.
464 - build system improvements.
465 - source code documentation updates.
467 -------------------------------------
468 0.3.6 (2009-12-07) "cubic continuity"
469 -------------------------------------
471 Quite a few bugs have been found and fixed since 0.3.5, so here's
472 another 0.3.x release. No new features.
474 - Always check return value of malloc().
475 - ogg vorbis/FEC: Do not write garbage after the audio file header.
476 - exit if root privileges could not be dropped.
477 - FEC: Fix computation of extra slices.
478 - oss: Fix check for empty input buffer.
479 - Avoid buffer underruns due to filter chain output buffer constraints.
480 - server: Fix assignment of afs_pid.
481 - Don't panic if the afs database contains unknown audio formats.
482 - http/dccp: Do not send the audio file header twice.
483 - FEC: Timing improvements.
485 ----------------------------------------------
486 0.4.0 (2009-11-10) "simultaneous independence"
487 ----------------------------------------------
489 Two significant changes which require the new version number: The
490 improved authentication dialog and the fact that the database code
491 has been moved to a library, libosl. To use the new version, you have
492 to generate new RSA keys, see INSTALL for details. A shell script is
493 provided for conversion of the 0.3 database to the new 0.4 format.
495 - stronger crypto for client authentication
496 - the database code has been moved to a library
497 - improved status item handling
498 - cleanup of the build system
499 - The "-V" option now also prints the git version
500 - the new parser-friendly listing mode for the ls and stat commands
501 - mandatory rc4 encryption
502 - major audio format handler cleanups
503 - (id3,...) tags are no longer stored as a combined string in the database
504 - new mood methods: artist_matches, title_matches, comment_matches,
505 album_matches, year_maches, year.
507 --------------------------------------------
508 0.3.5 (2009-09-21) "symplectic separability"
509 --------------------------------------------
511 Full client support for \*BSD Unixes, complete re-write of the ogg
512 vorbis audio format handler, various improvements all over the place
513 and the usual mix of bugfixes. This release marks the end of the 0.3
514 series if no serious problems show up.
516 - the new oss writer (supported on \*BSD and Linux)
517 - rewrite of the ogg vorbis audio format handler. It's
518 recommended to replace the chunk tables of existing ogg
519 vorbis files in the afs database by re-adding these files
521 - support for netmask subsets (Gerrit Renker)
522 - the new prebuffer filter
523 - improved signal handling
524 - variable fec output buffer size

532 -----------------------------------------
533 0.3.4 (2009-05-07) "elliptic inheritance"
534 -----------------------------------------
536 The new udp sender, forward error correction, colored logs and various
537 other improvements. As the udp sender does not depend on any special
538 libraries, it is built unconditionally.
540 - The udp sender replaces the ortp sender. The new code uses forward
541 error correction to protect against packet losses. Many thanks to
542 Gerrit Renker for providing ipv6 support.
543 - The default port for udp streaming now defaults to 8000, like
544 for the http and the dccp senders/receivers.
545 - Loglevels are now specified as symbolic names, e.g.
547 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
548 - para_server/para_audiod: Color support for log messages.
549 - new options for mp3dec: --ignore-crc, --bufsize
550 - new audiod option: --config-file.
551 - gengetopt cleanups.
552 - Improved help/man pages: The documentation of para_audiod,
553 para_recv, para_filter and para_write now also contains
554 all options of the available receivers/filters/writers. The
555 man page of para_fade contains a description of the different
557 - More source code documentation.
560 --------------------------------------------
561 0.3.3 (2008-12-01) "axiomatic perspectivity"
562 --------------------------------------------
564 Internal code cleanups, bug fixes, improved tag handling and the new
565 amplification filter.
567 - para_server uses the generic scheduling code.
568 - overhaul of the virtual streaming system.
569 - mp3: id3 version 2 support via libid3tag (optional)
570 - ogg: vorbis comment support.
571 - aac meta info support.
572 - mp3 audio format handler cleanups.
573 - new filter: "amp" to amplify the amplitude of the audio stream
574 - new status item/database entry: amplification. It is
575 used by the amp filter to pre-amplify the audio stream.
576 - fix a close-without-open bug in para_write.
577 - fix a bug in com_init() which was introduced in 0.3.2.
578 - better error diagnostics for para_client.
580 -----------------------------------------
581 0.3.2 (2008-04-11) "probabilistic parity"
582 -----------------------------------------
584 The new para_afh executable, scheduling and documentation improvements.
586 - new ls option: -lc (list chunk table)
587 - new executable: para_afh, the stand-alone audio file handler tool
588 - afs commands can send output more than SHMMAX (32MB on Linux). This
589 also reduces the memory usage of commands that produce large amounts
591 - major scheduler and audiod cleanups.
592 - more detailed and much nicer man pages.
594 ---------------------------------------
595 0.3.1 (2008-02-23) "liquid interaction"
596 ---------------------------------------
598 A mix of cleanups, bug fixes, improvements, and some new features. No
599 significant changes to the new database (osl) code, which is generally
602 - Share some similar/duplicate code between the http and the
604 - Generic access control lists for paraslash senders.
605 - dccp sender: Access control lists, connection limiting and support
606 for the allow,deny,on,off,help sender commands.
607 - The default dccp port changed from 5001 to 8000 (suggested by
609 - para_server starts even if not all public keys could be loaded.
610 - Audiod performance improvements.
611 - fix a bug in the "off" command of the http sender.
612 - fix some fd and memory leaks.
613 - Update to gengetopt-2.22.
615 -------------------------------------
616 0.3.0 (2008-01-12) "solar saturation"
617 -------------------------------------
619 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
622 Usually one might expect lots of new features AND a big increase in size
623 for a major release like this.
625 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
626 ever. The decrease in size is mostly due to the removal of some
627 graphical tools (which were only quick hacks anyway). But also the
628 fact that the mysql code is gone cuts down the size a bit.
630 Being independent of mysql comes at a cost: The fact that paraslash
631 now contains its own database (the object storage layer, osl) increases
632 the (stripped) binary size of para_server by ~50K on i386.
634 - no more restrictions on unique basenames.
635 - independent of mysql: The new self-contained object
636 storage layer (osl) replaces the mysql database.
637 - New executable para_fsck: Check integrity of osl tables.
639 - Reliable audio file move/rename detection.
640 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
641 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
643 - the new osl-based audio file selector (afs) replaces the random,
644 the playlist and the mysql selector of paraslash-0.2.x.
645 - IPv6 support (thanks to Gerrit Renker).
646 - paraslash-0.2.x streams are now called "moods". Writing
647 0.3.x-mood definitions should be both easier and more
648 powerful than writing 0.2.x-stream definitions.
649 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
650 been removed. The world is a better place without them. However,
651 para_gui is still there.
652 - afs tracks audio file selection also in playlist mode.
653 - few easy-to-use afs commands replace the many not-so-easy-to-use
654 mysql commands (and are available also in playlist mode).
655 - Improved error subsystem.
656 - The earth-shaking new logo.
658 -----------------------------------------
659 0.2.17 (2007-11-20) "isotropic threshold"
660 -----------------------------------------
662 Mainly bugfixes and cleanups in this version which marks the end of
663 the 0.2.x series if no serious bugs show up after the release.
665 - mysql_selector: fix a locking bug.
666 - universal chunk queueing.
667 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
669 - be more carful wrt. signed vs. unsigned argument passing.
670 - cleanup error.h and fix some references to invalid error
672 - update to gengetopt-2.21.
673 - update to ortp-0.13.1.
674 - autoconf: extend checks for headers, library functions and
675 compiler characteristics.
676 - Fix streaming of large mp3 files.
677 - Fix an off-by-one bug in playlist handling.
679 --------------------------------------
680 0.2.16 (2007-04-05) "neural discharge"
681 --------------------------------------
683 The main change in this release is the major audio format handler
684 cleanup which removes some similar/duplicate code and makes it easier
685 to implement plugins for other audio formats. Of course, the usual mix
686 of other improvements/changes/bugfixes also made it into the release.
688 - simplified audio format handlers (most of the handling functions
689 were moved one layer up to the virtual streaming system).
690 - para_server uses mmap to read audio files
691 - repositioning of mp3 streams is much faster, in particular for
692 jumping near the end of large mp3 files.
693 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
695 - fix a bug in para_filter that caused decoding of aac files
696 to start only after a few seconds.
697 - fix osx_writer hangs
698 - simplified dccp code (thanks to Gerrit Renker)
699 - the compress filter works also on big endian systems (ppc)
701 -----------------------------------------
702 0.2.15 (2007-02-16) "inductive resonance"
703 -----------------------------------------
705 Minor improvements, more documentation and a bunch of bug fixes.
707 - para_server: The server.users file is only read once on server
708 startup rather than for each connection
709 - mp3dec: Fix decoding of corrupt mp3 files
710 - afs (audio file sender) is now called vss (virtual streaming
711 system). Consequently, the permission flags specified in
712 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
713 become VSS_READ and VSS_WRITE respectively.
714 - para_audiod/para_filter: Fix a bug that caused the last chunk
715 of audio data not being written under certain circumstances
716 - audiod: compute the difference of server time and local time
718 - para_server/para_audiod: Fix some memory leaks
719 - documentation improvements
720 - configure.ac: fix checks for para_krell
723 -------------------------------------------
724 0.2.14 (2006-10-15) "transient singularity"
725 -------------------------------------------
727 The only major enhancement of this version is the osx writer which completes
728 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
729 until now for reasons beyond the scope of this changelog entry.
731 - new output plugin for Mac Os: the osx writer
732 - rename configure command line options from --enable-xxx-headers to
733 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
734 - configure: new command line options: --with-mad-headers,
735 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
736 - some robustness fixes
737 - dymamic audio format recognition for audiod
738 - para_server: new command line option: --autoplay_delay
739 - para_audiod: new command line option: --clock_diff_count
741 ---------------------------------------
742 0.2.13 (2006-07-14) "sonic convolution"
743 ---------------------------------------
745 A bunch of new features and core changes.
747 - the new paraslash scheduler, short and sweet.
748 - Support for m4a/mp4 files via the new aac audio format
749 handler/filter (requires libfaad).
750 - each writer has its own command line parser, just like
751 para_recv and para_filter.
752 - para_client and para_audioc use the error subsystem
753 - writers are integrated in para_audiod (currently linux-only)
754 - para_client is integrated in para_audiod
755 - random/playlist selector: improved info strings
756 - new audiod commands: tasks, kill
757 - update to libortp-0.10.1
758 - para_fade: wake time defaults to 8 hours from now
759 - update to autoconf-2.60
761 ------------------------------------------
762 0.2.12 (2006-05-12) "oriented abstraction"
763 ------------------------------------------
765 Many user-visible changes in this release and lots of new
768 - the new optional dccp sender/receiver. It uses the datagram
769 congestion control protocol. You'll need a fairly new kernel
771 - paraslash works on Mac OS X (thanks to Gerd Becker)
772 - para_play renamed to para_write
773 - modular output plugin design (writers) for para_write
774 - new file_writer output plugin for para_write
775 - compress filter speed improvements
776 - update to libortp-0.9.1
777 - update to gengetopt-2.17rc
778 - para_client no longer depends on libreadline (as the
779 code for the interactive mode was removed).
780 - gcc-2-95 is no longer a supported compiler. It may still
781 work, but it gets no more testing.
782 - the tarball no longer contains the screenshot images which
783 reduces its size quite a bit.
784 - configure: new command line options: --enable-mysql-headers
785 and --enable-mysql-libs
787 ------------------------------------
788 0.2.11 (2006-03-11) "atomic duality"
789 ------------------------------------
791 Here it is, the first paraslash release developed with git. There
792 are fairly many user-visible changes in this release. As two out of
793 the three "database tools" of paraslash don't use a database at all,
794 they are now called "audio file selectors" instead.
796 - the cdt command (change database tool) becomes chs (change
798 - no more colon separators: The syntax of some options of
799 para_audiod and para_filter have changed. Use --help for
800 more info (and some examples).
801 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
802 - switch from cvs to git (should've done that earlier)
803 - the new ipc subsystem
804 - new audio file selector: playlist
805 - para_server: the dopey selector is now called "random",
806 and is the default selector. Use the --selector option to
807 choose another selector at startup, or the chs command to
808 change the selector at runtime.
809 - X86_64 fixes (thanks to Steffen Klassert)
812 --------------------------------------
813 0.2.10 (2006-02-17) "cyclic attractor"
814 --------------------------------------
816 Huge documentation update, a scrollable window for para_gui, ortp
817 improvements, and of course many small fixes not mentioned here.
818 The diffstat below is rather misleading as most insertions are due
819 to the new source documentation.
822 - para_server also uses the new error subsystem
823 - lots of new documentation (UTSL)
825 - keysyms for cursor keys and for next/previous page keys
826 - scrollable output window
827 - new internal commands: scroll up/down, page up/down
828 - fix color of command output.
829 - ortp: the --chunk_time and --header flags are no longer needed
830 for para_recv/para_audiod as this information is now encoded in
831 each rtp packet sent by para_server.
833 -------------------------------------------
834 0.2.9 (2006-01-24) "progressive turbulence"
835 -------------------------------------------
837 Internal audiod receivers/filters, the new error subsystem and
838 a lot of small improvements.
840 - para_recv and para_filter are integrated into the para_audiod
841 binary, i.e. audiod no longer spawns a new process for
842 each receiver/filter. As para_recv and para_filter might be
843 useful as standalone programs, they still get built (linked
844 against the same object files that are also used for audiod).
845 - further ortp timing improvements should reduce the CPU usage
846 of the ortp receiver.
847 - improved audio grabbing. The 'grab' command of para_audiod
848 has its own set of command line options. Read the output of
849 "para_audioc help grab" for more info.
850 - oggdec: configurable input prebuffer size.
851 - the new error subsystem gives better error diagnostics
852 and reduces code size.
854 -----------------------------------------
855 0.2.8 (2006-01-02) "dynamic accumulation"
856 -----------------------------------------
858 The new modular filter design and the para_play-hangs bugfix.
860 - new executable: para_filter. It combines para_mp3dec,
861 para_oggdec and para_compress. It also adds a further filter
862 type, wav, that just inserts a wave header at the desired point
863 of the filter chain. All 'piping' is done in-memory (i.e. no
864 read/write operations are used).
865 - para_play: fix a stupid bug that caused it to hang under
866 certain circumstances.
868 -------------------------------------------
869 0.2.7 (2006-12-27) "transparent invariance"
870 -------------------------------------------
872 Not many user-visible changes but a fair amount of internal improvements.
874 - The http sender buffers data if it can not be sent
875 out immediately (because the socket is not writable). This
876 should prevent para_server from shutting down the connection
877 too early on a loaded network.
878 - para_play also prebuffers data if it is told to start at a
879 future time by the --start_time option.
880 - The return of para_recv: It combines para_ortp_recv and
881 para_http_recv. Use the --receiver option to switch between
882 the two. para_recv builds without libortp, but contains
883 only the http receiver in this case.
884 - update to ortp 0.8.1. As this ortp release contains incompatible
885 changes, para_recv-0.2.7 won't link against older ortp libs.
886 - improved ortp timings.
887 - use of gcc-extensions that #define away for non-gcc and
890 -------------------------------------------
891 0.2.6 (2005-10-29) "recursive compensation"
892 -------------------------------------------
894 Transparent session encryption (uses openssl's Alleged RC4 cipher),
895 the internal find command and several other improvements and cleanups.
897 - Encrypt the session if encryption is requested by the client
898 (default for para_client 0.2.6). This is backwards
899 compatible, so older clients can still connect to para_server
900 0.2.6. Use the new client option --plain to request an
901 uncrypted session (off by default, must be set to on in
902 order to connect to para_server 0.2.x with 0 <= x <= 5).
903 - para_server uses an internal function to locate audio files
904 rather than calling find(1). The server option
905 --mysql_audio_file_dir replaces --mysql_find_cmd.
906 - documentation update
908 - header file cleanup
909 - para_client code cleanup
910 - para_gui: faster display of output of display commands
912 ------------------------------------------
913 0.2.5 (2005-10-13) "aggressive resolution"
914 ------------------------------------------
916 This release adds internal senders, i.e. no more external programs are
917 spawned for sending out the audio data. There are two different senders
918 available: The http sender and the ortp sender (former para_send which
919 is no longer needed).
921 The new sender code has a plugin-like design so it can be easily
922 extended should there be be any future need for supporting another
923 network streaming protocol. All senders are completely independent of
924 each other. In particular, the http and the ortp sender can operate
927 - new server command: sender to control senders at runtime.
928 Read the output of "para_server -h" and "para_client help
929 sender" for more information.
930 - para_recv renamed to para_ortp_recv
931 - new executable: para_http_recv, a simple command line
933 - major afs/mp3/ogg code simplifications due to internal
935 - ogg timing improvements
936 - fix several minor memory leaks (found by valgrind)
937 - empty stream definitions work again
938 - com_ne(): ignore errors on remove
939 - audiod: fix segfault on server restart
941 ---------------------------------------
942 0.2.4 (2005-09-21) "toxic anticipation"
943 ---------------------------------------
945 Several small improvements, fixes and the new grab command.
948 - new command: "grab" to grab the output of the stream reader
949 or any filters. Read the output of "para_audioc help grab"
950 for more information.
953 - audioc: new command line option: --bufsize to specify a
954 buffer size different from the default size 8192.
955 - improved error diagnostics for para_play.
956 - new configure option: --enable-ssldir so search for openssl in
958 - sdl_gui: Make it look nice again for 1024x768
959 - server: report total size of memory allocated with sbrk by malloc,
960 new command line option: --announce_time
962 -----------------------------------------
963 0.2.3 (2005-09-01) "hydrophilic movement"
964 -----------------------------------------
966 Two new executables and major feature enhancements.
968 - audiod filters: It is now possible to specify arbitrary many
969 (including none) filters for each supported audio
970 format. This can be used e.g. for normalizing volume,
971 transforming or grabbing the audio stream, or for using
972 visualizers. Read the output of "para_audiod -h" for the
973 syntax of the new --filter_cmd option.
974 - new executable: para_play, a tiny alsa player. It
975 can play wave files or raw pcm (16 bit little endian)
977 - new executable: para_compress, a dynamic range compressor
978 intended to keep audio output at a consistent volume. Derived
979 from [AudioCompress](http://trikuare.cx/code/AudioCompress.html).
980 - audiod: New option: --stream_delay. This can be used in
981 a local network to syncronize the audio output of all
982 clients that play the same stream.
984 ------------------------------------------
985 0.2.2 (2005-08-19) "tangential excitation"
986 ------------------------------------------
988 Mostly internal changes in this release, but also some new commands
989 for the mysql database tool.
991 - cleanup exec.c, fix para_exec bug
992 - compile time loglevel (log messages below the given level
993 won't be compiled in, which reduces the size of the
995 - new log macros that shorten the size of the source code.
996 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
997 to send only zeros. With this workaround, para_audioc works
999 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
1000 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
1001 (new entry), "snp" (set numplayed). Read the manual for more
1004 ---------------------------------------
1005 0.2.1 (2005-08-15) "surreal experience"
1006 ---------------------------------------
1008 Here comes paraslash-0.2.1. It contains a couple of new features and,
1009 surprise, only minor bug fixes.
1011 - kill noisy mp3 debug message
1012 - cleanup of the build system
1013 - para_server and para_client directly use the crypto routines
1014 of the openssl library rather than invoking the openssl command
1016 - server/audiod: new option --user to switch to the given user
1017 when invoked as root. Read the output of "para_server -h" for
1019 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
1020 status. Default: "para_audioc stat"
1021 - sdl_gui: new option --pic_cmd to be used to download the picture.
1022 Default: "para_client pic"
1023 - audiod: 5 slots ought to be enough for everybody
1024 - audiod: new status item: Uptime, kill hup command
1026 ------------------------------------------
1027 0.2.0 (2005-08-06) "distributed diffusion"
1028 ------------------------------------------
1030 After several month of increased development activity, paraslash-0.2.0
1031 has arrived. It contains many new features and is much more
1032 self-contained than the old 0.1.x series. Enjoy!
1034 - para_server: fix hang on song change and crash on sighup.
1035 Speed up mysql queries. The DIR_LIKE macro is gone.
1036 - new executables: para_audiod, the local audio daemon that
1037 starts playback (uses SCM_CREDENTIALS socket magic) and
1038 para_audioc, the corresponding client.
1039 - new executables: para_mp3dec/para_oggdec, two really teensy
1040 decoders. para_mp3dec is based on libmad, para_oggdec requires
1042 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
1043 they are now called para_send and para_recv respectively.
1044 - documentation updates
1045 - para_gui is themable. For now there is the default theme that
1046 looks as before and the simple theme: blue and easy.
1047 - gui: audio streaming is now handled by audiod. Time display shows
1048 playback time rather than streaming time
1049 - slider: update to libzmw-0.2.0
1050 - para_krell: fix crash on server shutdown
1051 - switch from gzip to bzip2
1053 ----------------------------------------
1054 0.1.7 (2005-04-18) "melting penetration"
1055 ----------------------------------------
1057 The main change in this release is clearly the oggvorbis rewrite,
1058 but there are also lots of smaller changes. If you intend to use both
1059 the mp3 and the ogg plugin, it is recommended to use software mixing,
1060 e.g. the dmix plugin which is provided by ALSA.
1062 - new executables: para_ovsend and para_ovrecv for sending/receiving
1063 oggvorbis files via rtp. Requires the open rtp library. Get it at
1064 http://www.linphone.org/ortp/
1065 - rewrite of the ogg_vorbis core code
1066 - configure detects libzmw and, if detected, includes
1067 para_slider to the list of binaries to be built by make
1068 - server stream writers read from their associated fifo rather
1070 - slider: two new sliders, lastplayed and numplayed
1071 - fix nasty double free bug which caused random segfaults in case of
1072 mp3 files with invalid header information
1073 - gui: new command line option: --stream_timeout=seconds to
1074 deactivate a slot if it is idle for that many seconds (default=`5')
1077 ---------------------------------------
1078 0.1.6 (2005-03-05) "asymptotic balance"
1079 ---------------------------------------
1081 Only little user-visible changes in this release. Mainly bugfixes and
1082 core code cleanup. This is probably the most stable version ever if you
1085 - fix several memory leaks
1086 - rename default name of mysql database from "music" to "paraslash".
1087 Use para_server's --mysql_database option if you do not want to
1088 rename your old database.
1089 - rework ogg vorbis code
1090 - make update command work on mysql servers with LOCAL_INFILE
1092 - gui: improved stream I/O (slots)
1093 - simplified audio format API
1094 - para_pob_ogg is gone
1096 ------------------------------------
1097 0.1.5 (2004-12-31) "opaque eternity"
1098 ------------------------------------
1100 Let's slide gently into the new year.
1102 - new: para_slider (not built automatically, type "make
1103 para_slider" to build). A toy for those who always felt that
1104 creating stream definitions is difficult. See screenshots,
1105 README and FEATURES for more info.
1106 - improved signal handling. Fixes server segfault on SIGHUP
1107 for linux kernels newer than Aug 24 2004 and makes para_gui
1109 - reload database tool on SIGHUP
1110 - improved help message for sl
1111 - do not log "broken pipe" messages as errors. They are
1113 - fix wrong error message on permission errors
1115 -----------------------------------------
1116 0.1.4 (2004-12-19) "tunneling transition"
1117 -----------------------------------------
1119 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1120 Hopefully, most of them got wiped out with this release. Some
1121 enhancements went also in.
1123 - improved error diagnostics for all commands
1124 - stradd/picadd: overwrite previous contents if entry already
1125 exists, rather than returning errors
1126 - stradd: use current stream if invoked without args
1127 - faster (and hopefully more stable) ogg-vorbis handling
1128 - para_krell: reap children to avoid zombie-flooding in case
1129 no server is running
1130 - si: report also server pid
1131 - server: don't busy-loop if dbtool reports only invalid files.
1132 - gui: CTRL+C works again, fix stream_read command line option
1134 - fix mysql dbtool startup in case no database exists
1135 - many small fixes and cleanups
1137 ---------------------------------------
1138 0.1.3: (2004-12-10) "vanishing inertia"
1139 ---------------------------------------
1141 Starting from this release, the database tools are integrated in the
1142 server binary. This decreases server startup time, reduces code size
1143 and speeds up database commands. However, the layout of the underlying
1144 mysql database changed only slightly and 0.1.3 should be backwards
1145 compatible in that respect.
1149 - If mysql is not detected at compile time, or fails to init
