21 ---------------------------------------------
22 0.5.3 (2014-08-01) "symbolic synchronization"
23 ---------------------------------------------
25 Not many new features, but lots of fixes and usability improvements.
27 - para_gui has been converted to use the paraslash scheduler.
28 - Various alsa-related fixes, mostly for the raspberry pi.
29 - Many scheduler improvements and cleanups.

43 0.5.2 (2014-04-11) "orthogonal interior"
44 ----------------------------------------
46 The new sync filter, the AES_CTR128 stream cipher and the overhauled
47 network code are the highlights of this release. It also includes a
48 fair number of smaller fixes and improvements not mentioned here.
50 - The new sync filter synchronizes playback between multiple
52 - Connections between para_server and para_client are now
53 encrypted by means of AES rather than RC4 if both sides
54 support it. RC4 is still available as a fallback. This
55 feature is fully transparent, i.e. no command line options
56 are necessary, and a client linked against openssl can
57 speak with a server linked against libgcrypt and vice versa.
58 - Major cleanup of the networking subsystem.
59 - Improvements to para_fade: the new set mode, multi-channel
60 initial volumes, better error logging.
61 - The man pages of para_audiod, para_filter, para_recv, and
62 para_write contain the relevant options for receivers, filters,
63 writers. This broke in 0.5.0.
64 - ogg/vorbis latency improvements.
65 - Improved user manual.
66 - Minor fixes to avoid clang warnings.

72 0.5.1 (2013-12-20) "temporary implication"
73 ------------------------------------------
75 Lots of fixes and improvements all over the place, and a major overhaul
78 - Audiod improvements and fixes.
79 - Buffer tree robustness improvements.
80 - Cleanup of the mood subsystem.
81 - Fixes and cleanups for the flac decoder.
82 - Latency improvements for the ogg/opus decoder.
83 - Crypto support is now optional. On systems without
84 openssl/gcrypt, the build succeeds but para_server,
85 para_audiod, para_client won't be built.
86 - The build system now works for cross-compile setups.
87 - The dependency tree has been flattened, which speeds up
88 builds and avoids to recreate the man pages on every change.
89 - The error code helper has been rewritten from perl to C,
90 which further improves build time.
91 - Many small bugs in the build system have been identified

98 0.5.0 (2013-08-23) "invertible validity"
99 ----------------------------------------
101 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
103 - The sideband compatibility code has been removed, hence
104 sideband connections (introduced in 0.4.11) are now mandatory.
105 - Addblob commands can produce output.
106 - The stat command no longer sends garbage when para_server was
107 compiled against libgcrypt.
108 - Dependencies for gengetopt files are computed automatically.
109 This eliminates a constant source of build bugs.
110 - The setatt command now accepts file name patterns rather than only
112 - overview.pdf is now based on dia, a simple diagram creation program.
113 The new version is much more detailed and contains descriptions of
114 the various programs of the paraslash package.
115 - The separator of all multi-word options has been changed from
116 underscore to dash. For example --log_color becomes --log-color.
117 - Overhauled web pages and the new logo.

123 0.4.13 (2013-07-29) "spectral gravity"
124 --------------------------------------
126 One more 0.4.x release before the API-breaking changes for 0.5.0 go
127 in. The main features of this release are the ogg/opus audio format,
128 and UTF-8 support, but it includes also tons of other improvements
129 and fixes all over the place.
131 - New audio format: ogg/opus.
132 - UTF8 support for para_gui and the mp3 audio format handler.
133 - Scheduler improvements and fixes.
134 - The obsolete gettimeofday() function has been replaced
135 by clock_gettime() on systems which support it.
136 - Speed and usability improvements for para_gui.
137 - para_client now restores the fd flags of stdin and stdout
139 - Improved manual pages.
140 - Consistent version strings for all executables.
141 - Reduced dependencies on generated files result in fewer
142 recompilations on changes.
143 - Performance improvements for the compress filter.
144 - Improved downloads web page.
146 -----------------------------------------
147 0.4.12 (2012-12-20) "volatile relativity"
148 -----------------------------------------
149 The new command line player, the resample filter, ALSA support for
150 para_fade, and the improved build system are the highlights of this
151 release which probably marks the end of the 0.4.x series.
153 - The afh receiver and the para_play executable.
154 - The resample filter: A sample rate converter based on
156 - The "versions" directory has been removed from the master
157 branch. The tarballs of the old releases are now available
158 in the new "releases" branch.
159 - Overhaul of the build system: All generated files are now
160 written to the "build" directory.
161 - The modular mixer API and the alsa mixer.
162 - Minor fixes for the osx writer.
164 --------------------------------------
165 0.4.11 (2012-07-20) "mutual diversity"
166 --------------------------------------
168 The major feature in this release is the new sideband API for
169 client-server communication. This API will be used exclusively starting
170 with 0.5.0, which breaks backward compatibility but allows to get rid
171 of quite some compatibility code. Other noteworthy changes include
172 decoder latency improvements and a long-standing bug fix for the
175 - Sideband connections: If both para_server and para_client
176 support this feature, data is sent as a multiplexed stream.
177 - The --no_default_filters option of para_filter has been
179 - Several fixes and latency improvements to various decoders.
180 - The ALSA writer now limits the prebuffer time to 500ms.
181 - Documentation improvements.
182 - Overhaul of the command_util.sh script.
183 - Fixes for some minor problems found by the clang analyzer.
184 - Compiles (almost) without warnings on gcc-3.
185 - Robustness improvements of the buffer tree code.
187 ------------------------------------------
188 0.4.10 (2012-03-30) "heterogeneous vacuum"
189 ------------------------------------------
191 Nothing earth-shaking in this release, but quite a few usability
192 improvements and the usual mix of cleanups and fixes.
194 - The --no_default_filters option of para_filter has been
195 deprecated. It still works but has no effect and will be
196 removed in the next version.
197 - para_gui now prints also the stderr output of the executing
198 command in the bottom window.
199 - Cleanup and consolidation of the various wrappers for
200 write(), writev(), send() and friends.
201 - The obscure error messages on mmap() failures have been
202 replaced by meaningful messages. This affects mainly
204 - para_audioc: Cleanups and memory leak fixes.
205 - Test 0004-server no longer fails if para_server is not
207 - New configure options: --with-id3tag-{headers,libs}.
209 -------------------------------------
210 0.4.9 (2011-12-06) "hybrid causality"
211 -------------------------------------
213 Support for another audio format, interactive mode for para_client
214 and para_audiod and many small improvements/fixes all over the place.
216 - Support for flac, the free lossless audio codec.
217 - Fix for an endless loop in the mp3 decoder for certain
219 - When executed without specifying a command, para_client
220 and para_audioc start an interactive shell (requires
221 libreadline being installed). The interactive mode offers
222 full tab completion and command line history.
223 - autogen.sh now detects a distcc setup and adjusts the
224 parameter for the -j option of make accordingly.
225 - Shared memory areas are no longer restricted to 64K. We now
226 detect the maximal size of a shared memory area at runtime.
227 - cleanup of the internal uptime API.
228 - para_server prefaults the mmapped audio file to avoid
229 delays on slow media.
230 - A new test for the test-suite that exercises the
231 communication between para_server and para_audiod.
232 - The alsa writer eats up less CPU cycles when configured to
234 - Simplified and unified receiver code.
236 - Commands which print a list of matching audio files now
237 emit a meaningful error message if no audio file matched the
240 --------------------------------------
241 0.4.8 (2011-08-19) "nested assignment"
242 --------------------------------------
244 Gcrypt support, the overhauled osx writer and regex format specifiers
245 are the highlights of this release.
247 - support for libgcrypt as a drop-in replacement for openssl.
248 Run configure --enable-cryptolib=gcrypt to link against
249 libgcrypt. The two crypto implementations are compatible to
250 each other, i.e. a para_client executable linked against
251 gcrypt can connect to para_server linked against libssl
253 - Rewrite of the osx writer (output plugin for Mac OS).
254 - audiod: The format specifier for receivers, filters and
255 writers is now treated as a regular expression. This allows
256 to replace 5 lines in the config file (one for each audio
257 format) by one single line. See the manual for details.
258 - The *.cmdline.[ch] files are no longer contained in the released
259 tarballs. This reduces the size of the tarballs but requires
260 gengetopt to build the tarball.
261 - Compiles cleanly also with llvm/clang.
262 - Corrupt mp3 files are handled more gracefully.
263 - The alsa writer uses poll fds instead of computing timeouts.
264 - Cleanup of the generic writer API.
265 - sched: Optimized zero timeouts.
266 - vss timeout cleanups.
267 - oggdec fixes and improvements.
269 --------------------------------------
270 0.4.7 (2011-06-01) "infinite rollback"
271 --------------------------------------
273 The new ao writer, support for ssh RSA keys and a couple of other
276 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
277 platforms through the libao audio library.
278 - Support for RSA keys generated with ssh-keygen.
279 - configure: improved options for ogg/vorbis/speex.
280 - The git version reported by --version always matches HEAD.
281 - The autogen script detects the number of processors and
282 runs a parallel make if possible.
283 - Major cleanup of the crypto API.
284 - Documentation updates.
286 ------------------------------------------
287 0.4.6 (2011-03-31) "deterministic entropy"
288 ------------------------------------------
290 Lots of ogg/vorbis improvements, the new test suite, enhancements
291 for para_gui and a fair amount of other bug fixes.
293 - For DCCP/OGG streams the audio file header is only sent once
294 at the beginning of the stream rather than periodically
295 every five seconds. This reduces network traffic and the
297 - The vorbis comment header is replaced by an empty dummy header
298 before the header is sent over the network. This also results in
299 less network traffic and smaller FEC groups.
300 - The new "test" make target allows to perform some sanity checks prior
301 to installing the package.
302 - ogg timing fixes and performance improvements
303 - Scheduler improvements
304 - Proper exit codes for para_write
305 - para_gui: New option --theme to select a startup theme. Several
306 other improvements and fixes.
307 - aacdec error message cleanups
308 - simplified color error handling
310 --------------------------------------------
311 0.4.5 (2010-12-17) "symmetric randomization"
312 --------------------------------------------
314 Bug fixes, internal cleanups and variable-sized FEC slices.
316 - Contains a fix for an invalid-free-bug in the ogg audio format
318 - Switching off the DCCP sender works again.
319 - para_audiod handles crashes of para_server more robustly.
320 - Internal scheduler and writer cleanups.
321 - Reduced latency due to variable-sized FEC slices.
322 - Improved documentation and error diagnostics.
323 - The build of para_server is now optional, allowing the build
324 to succeed in case libosl is not installed.
326 ------------------------------------------
327 0.4.4 (2010-08-06) "persistent regularity"
328 ------------------------------------------
330 Support for yet another audio format, para_write improvements and
333 - Support for the speex codec.
334 - Support for sample formats other than 16 bit little endian.
335 - error2.h is now created by a perl script which speeds up configure
337 - Fix a bug in the aac decoder which could lead to segfaults in
338 para_filter/para_audiod.
339 - Fixes for autoconf-2.66.
341 ----------------------------------------
342 0.4.3 (2010-07-05) "imaginary radiation"
343 ----------------------------------------
345 Many improvements for the DCCP and the UDP transport, the new user
346 manual and the usual mix of bug fixes and internal improvements.
348 - FEC support for the DCCP sender (Gerrit Renker). The new
349 --dccp_max_slice_size, --dccp_data_slices_per_group and
350 --dccp_slices_per_group options can be used to set the FEC
351 parameters for the DCCP transport.
352 - DNS lookups for UDP targets (Gerrit Renker).
353 - The new user manual replaces the README, README.afs, REQUIREMENTS
354 and INSTALL documents.
355 - Fix an end-of-file detection bug in the oggdec filter.
356 - The new nonblock API.
357 - Both options of the oggdec filter have been removed.
358 - New debug mode for the internal scheduler.
360 ------------------------------------------
361 0.4.2 (2010-04-23) "associative expansion"
362 ------------------------------------------
364 It's been some time since the last release, but finally here is
365 paraslash-0.4.2. The bulk of the changes comes from the new buffer
366 tree API, but there are changes all over the tree. Mainly performance
367 and usability improvements, but also quite some bug fixes.
369 - The new buffer tree API.
370 - DCCP: Support for CCID negotiation (Gerrit Renker).
371 - UDP robustness fixes.
372 - The --bufsize option for mp3dec is gone as it no longer makes sense
373 for the new buffer tree API.
374 - Fix audible buffer underruns for wma streams.
375 - The alsa writer no longer prints meaningless underrun durations.
376 - audiod: Defaults work also for udp streams. If no filter is
377 given for an audio format that is received via upd, fecdec is
378 automatically added as the first filter (along with the decoder).
380 ---------------------------------------
381 0.4.1 (2009-12-22) "concurrent horizon"
382 ---------------------------------------
384 Support for another audio format, minor feature enhancements and lots of bug
385 fixes. All fixes that have been accumulated in the maint branch (in particular
386 those mentionened in the 0.3.6 release notes) appear in this release as well.
389 - new afh option: --human to activate human-readable output.
390 - new server/audiod option: --log-timing to print timing information.
391 - build system improvements.
392 - source code documentation updates.
394 -------------------------------------
395 0.3.6 (2009-12-07) "cubic continuity"
396 -------------------------------------
398 Quite a few bugs have been found and fixed since 0.3.5, so here's
399 another 0.3.x release. No new features.
401 - Always check return value of malloc().
402 - ogg vorbis/FEC: Do not write garbage after the audio file header.
403 - exit if root privileges could not be dropped.
404 - FEC: Fix computation of extra slices.
405 - oss: Fix check for empty input buffer.
406 - Avoid buffer underruns due to filter chain output buffer constraints.
407 - server: Fix assignment of afs_pid.
408 - Don't panic if the afs database contains unknown audio formats.
409 - http/dccp: Do not send the audio file header twice.
410 - FEC: Timing improvements.
412 ----------------------------------------------
413 0.4.0 (2009-11-10) "simultaneous independence"
414 ----------------------------------------------
416 Two significant changes which require the new version number: The
417 improved authentication dialog and the fact that the database code
418 has been moved to a library, libosl. To use the new version, you have
419 to generate new RSA keys, see INSTALL for details. A shell script is
420 provided for conversion of the 0.3 database to the new 0.4 format.
422 - stronger crypto for client authentication
423 - the database code has been moved to a library
424 - improved status item handling
425 - cleanup of the build system
426 - The "-V" option now also prints the git version
427 - the new parser-friendly listing mode for the ls and stat commands
428 - mandatory rc4 encryption
429 - major audio format handler cleanups
430 - (id3,...) tags are no longer stored as a combined string in the database
431 - new mood methods: artist_matches, title_matches, comment_matches,
432 album_matches, year_maches, year.
434 --------------------------------------------
435 0.3.5 (2009-09-21) "symplectic separability"
436 --------------------------------------------
438 Full client support for *BSD Unixes, complete re-write of the ogg
439 vorbis audio format handler, various improvements all over the place
440 and the usual mix of bugfixes. This release marks the end of the 0.3
441 series if no serious problems show up.
443 - the new oss writer (supported on *BSD and Linux)
444 - rewrite of the ogg vorbis audio format handler. It's
445 recommended to replace the chunk tables of existing ogg
446 vorbis files in the afs database by re-adding these files
448 - support for netmask subsets (Gerrit Renker)
449 - the new prebuffer filter
450 - improved signal handling
451 - variable fec output buffer size
452 - improved FEC timing fixes audible buffer underruns in UDP mode
453 - --log_color actually works
454 - new ls option: -d (print dates as seconds after the epoch)
455 - update to gengetopt 2.22.2
456 - support for RSA keys of size > 512 bits
457 - new option "mixer_channel" for para_fade
459 -----------------------------------------
460 0.3.4 (2009-05-07) "elliptic inheritance"
461 -----------------------------------------
463 The new udp sender, forward error correction, colored logs and various
464 other improvements. As the udp sender does not depend on any special
465 libraries, it is built unconditionally.
467 - The udp sender replaces the ortp sender. The new code uses forward
468 error correction to protect against packet losses. Many thanks to
469 Gerrit Renker for providing ipv6 support.
470 - The default port for udp streaming now defaults to 8000, like
471 for the http and the dccp senders/receivers.
472 - Loglevels are now specified as symbolic names, e.g.
474 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
475 - para_server/para_audiod: Color support for log messages.
476 - new options for mp3dec: --ignore-crc, --bufsize
477 - new audiod option: --config-file.
478 - gengetopt cleanups.
479 - Improved help/man pages: The documentation of para_audiod,
480 para_recv, para_filter and para_write now also contains
481 all options of the available receivers/filters/writers. The
482 man page of para_fade contains a description of the different
484 - More source code documentation.
487 --------------------------------------------
488 0.3.3 (2008-12-01) "axiomatic perspectivity"
489 --------------------------------------------
491 Internal code cleanups, bug fixes, improved tag handling and the new
492 amplification filter.
494 - para_server uses the generic scheduling code.
495 - overhaul of the virtual streaming system.
496 - mp3: id3 version 2 support via libid3tag (optional)
497 - ogg: vorbis comment support.
498 - aac meta info support.
499 - mp3 audio format handler cleanups.
500 - new filter: "amp" to amplify the amplitude of the audio stream
501 - new status item/database entry: amplification. It is
502 used by the amp filter to pre-amplify the audio stream.
503 - fix a close-without-open bug in para_write.
504 - fix a bug in com_init() which was introduced in 0.3.2.
505 - better error diagnostics for para_client.
507 -----------------------------------------
508 0.3.2 (2008-04-11) "probabilistic parity"
509 -----------------------------------------
511 The new para_afh executable, scheduling and documentation improvements.
513 - new ls option: -lc (list chunk table)
514 - new executable: para_afh, the stand-alone audio file handler tool
515 - afs commands can send output more than SHMMAX (32MB on Linux). This
516 also reduces the memory usage of commands that produce large amounts
518 - major scheduler and audiod cleanups.
519 - more detailed and much nicer man pages.
521 ---------------------------------------
522 0.3.1 (2008-02-23) "liquid interaction"
523 ---------------------------------------
525 A mix of cleanups, bug fixes, improvements, and some new features. No
526 significant changes to the new database (osl) code, which is generally
529 - Share some similar/duplicate code between the http and the
531 - Generic access control lists for paraslash senders.
532 - dccp sender: Access control lists, connection limiting and support
533 for the allow,deny,on,off,help sender commands.
534 - The default dccp port changed from 5001 to 8000 (suggested by
536 - para_server starts even if not all public keys could be loaded.
537 - Audiod performance improvements.
538 - fix a bug in the "off" command of the http sender.
539 - fix some fd and memory leaks.
540 - Update to gengetopt-2.22.
542 -------------------------------------
543 0.3.0 (2008-01-12) "solar saturation"
544 -------------------------------------
546 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
549 Usually one might expect lots of new features AND a big increase in size
550 for a major release like this.
552 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
553 ever. The decrease in size is mostly due to the removal of some
554 graphical tools (which were only quick hacks anyway). But also the
555 fact that the mysql code is gone cuts down the size a bit.
557 Being independent of mysql comes at a cost: The fact that paraslash
558 now contains its own database (the object storage layer, osl) increases
559 the (stripped) binary size of para_server by ~50K on i386.
561 - no more restrictions on unique basenames.
562 - independent of mysql: The new self-contained object
563 storage layer (osl) replaces the mysql database.
564 - New executable para_fsck: Check integrity of osl tables.
566 - Reliable audio file move/rename detection.
567 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
568 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
570 - the new osl-based audio file selector (afs) replaces the random,
571 the playlist and the mysql selector of paraslash-0.2.x.
572 - IPv6 support (thanks to Gerrit Renker).
573 - paraslash-0.2.x streams are now called "moods". Writing
574 0.3.x-mood definitions should be both easier and more
575 powerful than writing 0.2.x-stream definitions.
576 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
577 been removed. The world is a better place without them. However,
578 para_gui is still there.
579 - afs tracks audio file selection also in playlist mode.
580 - few easy-to-use afs commands replace the many not-so-easy-to-use
581 mysql commands (and are available also in playlist mode).
582 - Improved error subsystem.
583 - The earth-shaking new logo.
585 -----------------------------------------
586 0.2.17 (2007-11-20) "isotropic threshold"
587 -----------------------------------------
589 Mainly bugfixes and cleanups in this version which marks the end of
590 the 0.2.x series if no serious bugs show up after the release.
592 - mysql_selector: fix a locking bug.
593 - universal chunk queueing.
594 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
596 - be more carful wrt. signed vs. unsigned argument passing.
597 - cleanup error.h and fix some references to invalid error
599 - update to gengetopt-2.21.
600 - update to ortp-0.13.1.
601 - autoconf: extend checks for headers, library functions and
602 compiler characteristics.
603 - Fix streaming of large mp3 files.
604 - Fix an off-by-one bug in playlist handling.
606 --------------------------------------
607 0.2.16 (2007-04-05) "neural discharge"
608 --------------------------------------
610 The main change in this release is the major audio format handler
611 cleanup which removes some similar/duplicate code and makes it easier
612 to implement plugins for other audio formats. Of course, the usual mix
613 of other improvements/changes/bugfixes also made it into the release.
615 - simplified audio format handlers (most of the handling functions
616 were moved one layer up to the virtual streaming system).
617 - para_server uses mmap to read audio files
618 - repositioning of mp3 streams is much faster, in particular for
619 jumping near the end of large mp3 files.
620 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
622 - fix a bug in para_filter that caused decoding of aac files
623 to start only after a few seconds.
624 - fix osx_writer hangs
625 - simplified dccp code (thanks to Gerrit Renker)
626 - the compress filter works also on big endian systems (ppc)
628 -----------------------------------------
629 0.2.15 (2007-02-16) "inductive resonance"
630 -----------------------------------------
632 Minor improvements, more documentation and a bunch of bug fixes.
634 - para_server: The server.users file is only read once on server
635 startup rather than for each connection
636 - mp3dec: Fix decoding of corrupt mp3 files
637 - afs (audio file sender) is now called vss (virtual streaming
638 system). Consequently, the permission flags specified in
639 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
640 become VSS_READ and VSS_WRITE respectively.
641 - para_audiod/para_filter: Fix a bug that caused the last chunk
642 of audio data not being written under certain circumstances
643 - audiod: compute the difference of server time and local time
645 - para_server/para_audiod: Fix some memory leaks
646 - documentation improvements
647 - configure.ac: fix checks for para_krell
650 -------------------------------------------
651 0.2.14 (2006-10-15) "transient singularity"
652 -------------------------------------------
654 The only major enhancement of this version is the osx writer which completes
655 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
656 until now for reasons beyond the scope of this changelog entry.
658 - new output plugin for Mac Os: the osx writer
659 - rename configure command line options from --enable-xxx-headers to
660 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
661 - configure: new command line options: --with-mad-headers,
662 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
663 - some robustness fixes
664 - dymamic audio format recognition for audiod
665 - para_server: new command line option: --autoplay_delay
666 - para_audiod: new command line option: --clock_diff_count
668 ---------------------------------------
669 0.2.13 (2006-07-14) "sonic convolution"
670 ---------------------------------------
672 A bunch of new features and core changes.
674 - the new paraslash scheduler, short and sweet.
675 - Support for m4a/mp4 files via the new aac audio format
676 handler/filter (requires libfaad).
677 - each writer has its own command line parser, just like
678 para_recv and para_filter.
679 - para_client and para_audioc use the error subsystem
680 - writers are integrated in para_audiod (currently linux-only)
681 - para_client is integrated in para_audiod
682 - random/playlist selector: improved info strings
683 - new audiod commands: tasks, kill
684 - update to libortp-0.10.1
685 - para_fade: wake time defaults to 8 hours from now
686 - update to autoconf-2.60
688 ------------------------------------------
689 0.2.12 (2006-05-12) "oriented abstraction"
690 ------------------------------------------
692 Many user-visible changes in this release and lots of new
696 - the new optional dccp sender/receiver. It uses the datagram
697 congestion control protocol. You'll need a fairly new kernel
699 - paraslash works on Mac OS X (thanks to Gerd Becker)
700 - para_play renamed to para_write
701 - modular output plugin design (writers) for para_write
702 - new file_writer output plugin for para_write
703 - compress filter speed improvements
704 - update to libortp-0.9.1
705 - update to gengetopt-2.17rc
706 - para_client no longer depends on libreadline (as the
707 code for the interactive mode was removed).
708 - gcc-2-95 is no longer a supported compiler. It may still
709 work, but it gets no more testing.
710 - the tarball no longer contains the screenshot images which
711 reduces its size quite a bit.
712 - configure: new command line options: --enable-mysql-headers
713 and --enable-mysql-libs
715 ------------------------------------
716 0.2.11 (2006-03-11) "atomic duality"
717 ------------------------------------
719 Here it is, the first paraslash release developed with git. There
720 are fairly many user-visible changes in this release. As two out of
721 the three "database tools" of paraslash don't use a database at all,
722 they are now called "audio file selectors" instead.
725 - the cdt command (change database tool) becomes chs (change
727 - no more colon separators: The syntax of some options of
728 para_audiod and para_filter have changed. Use --help for
729 more info (and some examples).
730 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
731 - switch from cvs to git (should've done that earlier)
732 - the new ipc subsystem
733 - new audio file selector: playlist
734 - para_server: the dopey selector is now called "random",
735 and is the default selector. Use the --selector option to
736 choose another selector at startup, or the chs command to
737 change the selector at runtime.
738 - X86_64 fixes (thanks to Steffen Klassert)
741 --------------------------------------
742 0.2.10 (2006-02-17) "cyclic attractor"
743 --------------------------------------
745 Huge documentation update, a scrollable window for para_gui, ortp
746 improvements, and of course many small fixes not mentioned here.
747 The diffstat below is rather misleading as most insertions are due
748 to the new source documentation.
751 - para_server also uses the new error subsystem
752 - lots of new documentation (UTSL)
754 - keysyms for cursor keys and for next/previous page keys
755 - scrollable output window
756 - new internal commands: scroll up/down, page up/down
757 - fix color of command output.
758 - ortp: the --chunk_time and --header flags are no longer needed
759 for para_recv/para_audiod as this information is now encoded in
760 each rtp packet sent by para_server.
762 -------------------------------------------
763 0.2.9 (2006-01-24) "progressive turbulence"
764 -------------------------------------------
766 Internal audiod receivers/filters, the new error subsystem and
767 a lot of small improvements.
769 - para_recv and para_filter are integrated into the para_audiod
770 binary, i.e. audiod no longer spawns a new process for
771 each receiver/filter. As para_recv and para_filter might be
772 useful as standalone programs, they still get built (linked
773 against the same object files that are also used for audiod).
774 - further ortp timing improvements should reduce the CPU usage
775 of the ortp receiver.
776 - improved audio grabbing. The 'grab' command of para_audiod
777 has its own set of command line options. Read the output of
778 "para_audioc help grab" for more info.
779 - oggdec: configurable input prebuffer size.
780 - the new error subsystem gives better error diagnostics
781 and reduces code size.
783 -----------------------------------------
784 0.2.8 (2006-01-02) "dynamic accumulation"
785 -----------------------------------------
787 The new modular filter design and the para_play-hangs bugfix.
789 - new executable: para_filter. It combines para_mp3dec,
790 para_oggdec and para_compress. It also adds a further filter
791 type, wav, that just inserts a wave header at the desired point
792 of the filter chain. All 'piping' is done in-memory (i.e. no
793 read/write operations are used).
794 - para_play: fix a stupid bug that caused it to hang under
795 certain circumstances.
797 -------------------------------------------
798 0.2.7 (2006-12-27) "transparent invariance"
799 -------------------------------------------
801 Not many user-visible changes but a fair amount of internal improvements.
804 - The http sender buffers data if it can not be sent
805 out immediately (because the socket is not writable). This
806 should prevent para_server from shutting down the connection
807 too early on a loaded network.
808 - para_play also prebuffers data if it is told to start at a
809 future time by the --start_time option.
810 - The return of para_recv: It combines para_ortp_recv and
811 para_http_recv. Use the --receiver option to switch between
812 the two. para_recv builds without libortp, but contains
813 only the http receiver in this case.
814 - update to ortp 0.8.1. As this ortp release contains incompatible
815 changes, para_recv-0.2.7 won't link against older ortp libs.
816 - improved ortp timings.
817 - use of gcc-extensions that #define away for non-gcc and
820 -------------------------------------------
821 0.2.6 (2005-10-29) "recursive compensation"
822 -------------------------------------------
824 Transparent session encryption (uses openssl's Alleged RC4 cipher),
825 the internal find command and several other improvements and cleanups.
827 - Encrypt the session if encryption is requested by the client
828 (default for para_client 0.2.6). This is backwards
829 compatible, so older clients can still connect to para_server
830 0.2.6. Use the new client option --plain to request an
831 uncrypted session (off by default, must be set to on in
832 order to connect to para_server 0.2.x with 0 <= x <= 5).
833 - para_server uses an internal function to locate audio files
834 rather than calling find(1). The server option
835 --mysql_audio_file_dir replaces --mysql_find_cmd.
836 - documentation update
838 - header file cleanup
839 - para_client code cleanup
840 - para_gui: faster display of output of display commands
842 ------------------------------------------
843 0.2.5 (2005-10-13) "aggressive resolution"
844 ------------------------------------------
846 This release adds internal senders, i.e. no more external programs are
847 spawned for sending out the audio data. There are two different senders
848 available: The http sender and the ortp sender (former para_send which
849 is no longer needed).
851 The new sender code has a plugin-like design so it can be easily
852 extended should there be be any future need for supporting another
853 network streaming protocol. All senders are completely independent of
854 each other. In particular, the http and the ortp sender can operate
857 - new server command: sender to control senders at runtime.
858 Read the output of "para_server -h" and "para_client help
859 sender" for more information.
860 - para_recv renamed to para_ortp_recv
861 - new executable: para_http_recv, a simple command line
863 - major afs/mp3/ogg code simplifications due to internal
865 - ogg timing improvements
866 - fix several minor memory leaks (found by valgrind)
867 - empty stream definitions work again
868 - com_ne(): ignore errors on remove
869 - audiod: fix segfault on server restart
871 ---------------------------------------
872 0.2.4 (2005-09-21) "toxic anticipation"
873 ---------------------------------------
875 Several small improvements, fixes and the new grab command.
878 - new command: "grab" to grab the output of the stream reader
879 or any filters. Read the output of "para_audioc help grab"
880 for more information.
883 - audioc: new command line option: --bufsize to specify a
884 buffer size different from the default size 8192.
885 - improved error diagnostics for para_play.
886 - new configure option: --enable-ssldir so search for openssl in
888 - sdl_gui: Make it look nice again for 1024x768
889 - server: report total size of memory allocated with sbrk by malloc,
890 new command line option: --announce_time
892 -----------------------------------------
893 0.2.3 (2005-09-01) "hydrophilic movement"
894 -----------------------------------------
896 Two new executables and major feature enhancements.
898 - audiod filters: It is now possible to specify arbitrary many
899 (including none) filters for each supported audio
900 format. This can be used e.g. for normalizing volume,
901 transforming or grabbing the audio stream, or for using
902 visualizers. Read the output of "para_audiod -h" for the
903 syntax of the new --filter_cmd option.
904 - new executable: para_play, a tiny alsa player. It
905 can play wave files or raw pcm (16 bit little endian)
907 - new executable: para_compress, a dynamic range compressor
908 intended to keep audio output at a consistent volume. Derived
909 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
910 - audiod: New option: --stream_delay. This can be used in
911 a local network to syncronize the audio output of all
912 clients that play the same stream.
914 ------------------------------------------
915 0.2.2 (2005-08-19) "tangential excitation"
916 ------------------------------------------
918 Mostly internal changes in this release, but also some new commands
919 for the mysql database tool.
921 - cleanup exec.c, fix para_exec bug
922 - compile time loglevel (log messages below the given level
923 won't be compiled in, which reduces the size of the
925 - new log macros that shorten the size of the source code.
926 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
927 to send only zeros. With this workaround, para_audioc works
929 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
930 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
931 (new entry), "snp" (set numplayed). Read the manual for more
934 ---------------------------------------
935 0.2.1 (2005-08-15) "surreal experience"
936 ---------------------------------------
938 Here comes paraslash-0.2.1. It contains a couple of new features and,
939 surprise, only minor bug fixes.
941 - kill noisy mp3 debug message
942 - cleanup of the build system
943 - para_server and para_client directly use the crypto routines
944 of the openssl library rather than invoking the openssl command
946 - server/audiod: new option --user to switch to the given user
947 when invoked as root. Read the output of "para_server -h" for
949 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
950 status. Default: "para_audioc stat"
951 - sdl_gui: new option --pic_cmd to be used to download the picture.
952 Default: "para_client pic"
953 - audiod: 5 slots ought to be enough for everybody
954 - audiod: new status item: Uptime, kill hup command
956 ------------------------------------------
957 0.2.0 (2005-08-06) "distributed diffusion"
958 ------------------------------------------
960 After several month of increased development activity, paraslash-0.2.0
961 has arrived. It contains many new features and is much more
962 self-contained than the old 0.1.x series. Enjoy!
965 - para_server: fix hang on song change and crash on sighup.
966 Speed up mysql queries. The DIR_LIKE macro is gone.
967 - new executables: para_audiod, the local audio daemon that
968 starts playback (uses SCM_CREDENTIALS socket magic) and
969 para_audioc, the corresponding client.
970 - new executables: para_mp3dec/para_oggdec, two really teensy
971 decoders. para_mp3dec is based on libmad, para_oggdec requires
973 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
974 they are now called para_send and para_recv respectively.
975 - documentation updates
976 - para_gui is themable. For now there is the default theme that
977 looks as before and the simple theme: blue and easy.
978 - gui: audio streaming is now handled by audiod. Time display shows
979 playback time rather than streaming time
980 - slider: update to libzmw-0.2.0
981 - para_krell: fix crash on server shutdown
982 - switch from gzip to bzip2
984 ----------------------------------------
985 0.1.7 (2005-04-18) "melting penetration"
986 ----------------------------------------
988 The main change in this release is clearly the oggvorbis rewrite,
989 but there are also lots of smaller changes. If you intend to use both
990 the mp3 and the ogg plugin, it is recommended to use software mixing,
991 e.g. the dmix plugin which is provided by ALSA.
993 - new executables: para_ovsend and para_ovrecv for sending/receiving
994 oggvorbis files via rtp. Requires the open rtp library. Get it at
995 http://www.linphone.org/ortp/
996 - rewrite of the ogg_vorbis core code
997 - configure detects libzmw and, if detected, includes
998 para_slider to the list of binaries to be built by make
999 - server stream writers read from their associated fifo rather
1001 - slider: two new sliders, lastplayed and numplayed
1002 - fix nasty double free bug which caused random segfaults in case of
1003 mp3 files with invalid header information
1004 - gui: new command line option: --stream_timeout=seconds to
1005 deactivate a slot if it is idle for that many seconds (default=`5')
1008 ---------------------------------------
1009 0.1.6 (2005-03-05) "asymptotic balance"
1010 ---------------------------------------
1012 Only little user-visible changes in this release. Mainly bugfixes and
1013 core code cleanup. This is probably the most stable version ever if you
1016 - fix several memory leaks
1017 - rename default name of mysql database from "music" to "paraslash".
1018 Use para_server's --mysql_database option if you do not want to
1019 rename your old database.
1020 - rework ogg vorbis code
1021 - make update command work on mysql servers with LOCAL_INFILE
1023 - gui: improved stream I/O (slots)
1024 - simplified audio format API
1025 - para_pob_ogg is gone
1027 ------------------------------------
1028 0.1.5 (2004-12-31) "opaque eternity"
1029 ------------------------------------
1031 Let's slide gently into the new year.
1033 - new: para_slider (not built automatically, type "make
1034 para_slider" to build). A toy for those who always felt that
1035 creating stream definitions is difficult. See screenshots,
1036 README and FEATURES for more info.
1037 - improved signal handling. Fixes server segfault on SIGHUP
1038 for linux kernels newer than Aug 24 2004 and makes para_gui
1040 - reload database tool on SIGHUP
1041 - improved help message for sl
1042 - do not log "broken pipe" messages as errors. They are
1044 - fix wrong error message on permission errors
1046 -----------------------------------------
1047 0.1.4 (2004-12-19) "tunneling transition"
1048 -----------------------------------------
1050 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1051 Hopefully, most of them got wiped out with this release. Some
1052 enhancements went also in.
1054 - improved error diagnostics for all commands
1055 - stradd/picadd: overwrite previous contents if entry already
1056 exists, rather than returning errors
1057 - stradd: use current stream if invoked without args
1058 - faster (and hopefully more stable) ogg-vorbis handling
1059 - para_krell: reap children to avoid zombie-flooding in case
1060 no server is running
1061 - si: report also server pid
1062 - server: don't busy-loop if dbtool reports only invalid files.
1063 - gui: CTRL+C works again, fix stream_read command line option
1065 - fix mysql dbtool startup in case no database exists
1066 - many small fixes and cleanups
1068 ---------------------------------------
1069 0.1.3: (2004-12-10) "vanishing inertia"
1070 ---------------------------------------
1072 Starting from this release, the database tools are integrated in the
1073 server binary. This decreases server startup time, reduces code size
1074 and speeds up database commands. However, the layout of the underlying
1075 mysql database changed only slightly and 0.1.3 should be backwards
1076 compatible in that respect.
1080 - If mysql is not detected at compile time, or fails to init
1081 at runtime, fall back to the dopey database tool which should
1083 - para_dbtool and dbtool.conf are gone. All mysql specific
1084 options are read from server.conf and are prefixed by 'mysql_'.
1085 - new command: cdt (change database tool)
1086 - new command line option: dbtool (choose startup database tool)
1087 - The name of current stream is now stored in the database,
1088 so paraslash remembers its current stream when restarted.
1089 - new command: csp (change stream and play)
1090 - para_gui also reports current database tool and server uptime
1092 -------------------------------------------
1093 0.1.2: (2004-11-28) "spherical fluctuation"
1094 -------------------------------------------
1096 Point release before the big dbtool changes go in.
1098 - dbtool: rename ca to cam (copy all meta data). It now also
1099 copies numplayed and lastplayed time as well as the picture
1101 - fix endless-loop-bug caused by mp3 files with invalid header
1103 -----------------------------------------
1104 0.1.1: (2004-11-05) "floating atmosphere"
1105 -----------------------------------------
1108 - new dbtool command: mbox. Browse your sound-file collection
1109 with your favorite mail reader.
1110 - several small fixes
1112 -------------------------------------
1113 0.1.0: (2004-10-22) "rotating cortex"
1114 -------------------------------------
1116 - fix logging bug for loglevel > VERBOSE
1118 - correct timings for vbr mp3s
1119 - modular audio format support
1120 - ogg-vorbis support (experimental)
1121 - new server option: autoplay
1123 -----------------------------------------
1124 0.0.99: (2004-07-25) "harmonic deviation"
1125 -----------------------------------------
1127 - rename projectname from icc to paraslash (play, archive, rate
1128 and stream large audio sets happily)
1129 - paraslash is no longer restricted to one particular audio
1131 - new dbtool commands (stradd, strq, strdel) for easy stream
1132 managment w/o configuration file. That obsoletes stream_defs
1133 file/config option for dbtool.
1134 - picadd accepts jpeg data from stdin
1135 - new server commands: ps (select previous stream), sc (song change)
1136 - new default pictures for sdl_gui
1137 - gui: new key_map option for binding commands and internal
1138 functions to arbitrary keys, nice help screen, rip out
1139 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1140 show silly logo on startup
1141 - new executables: para_fade for fading volume, para_dbadm for
1142 manipulating attributes
1143 - cdb adds _all_ tables to mysql database
1144 - revised and beautified documentation
1145 - sample dbtool rewritten in C
1148 ---------------------------------------------
1149 0.0.98: (2003-12-26) "incremental smoothness"
1150 ---------------------------------------------
1152 - kick icecast in favour of poc. That removes some races and reduces
1153 core code considerably.
1154 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1155 give finer info on afs' status.
1156 - gui can start decoder (see config options). Further new gui
1157 commands: refresh (^L), jmp (F1-F10)
1158 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1159 terminates gui. This fixes dead instances consuming memory
