5 0.5.3 (2014-08-01) "symbolic synchronization"
6 ---------------------------------------------
8 Not many new features, but lots of fixes and usability improvements.
10 - para_gui has been converted to use the paraslash scheduler.
11 - Various alsa-related fixes, mostly for the raspberry pi.
12 - Many scheduler improvements and cleanups.
13 - The test suite has been extended to include sanity checks
14 for the generated man pages.
15 - ao_writer fixes. This writer was in a quite bad shape. Many
16 serious bugs have been fixed.
17 - new audiod command: version.
18 - Minor improvements to the bitstream API.
19 - The cpsi command now prints a meaningful error message if
20 none of the given patterns matched any audio file.

26 0.5.2 (2014-04-11) "orthogonal interior"
27 ----------------------------------------
29 The new sync filter, the AES_CTR128 stream cipher and the overhauled
30 network code are the highlights of this release. It also includes a
31 fair number of smaller fixes and improvements not mentioned here.
33 - The new sync filter synchronizes playback between multiple
35 - Connections between para_server and para_client are now
36 encrypted by means of AES rather than RC4 if both sides
37 support it. RC4 is still available as a fallback. This
38 feature is fully transparent, i.e. no command line options
39 are necessary, and a client linked against openssl can
40 speak with a server linked against libgcrypt and vice versa.
41 - Major cleanup of the networking subsystem.
42 - Improvements to para_fade: the new set mode, multi-channel
43 initial volumes, better error logging.
44 - The man pages of para_audiod, para_filter, para_recv, and
45 para_write contain the relevant options for receivers, filters,
46 writers. This broke in 0.5.0.
47 - ogg/vorbis latency improvements.
48 - Improved user manual.
49 - Minor fixes to avoid clang warnings.

55 0.5.1 (2013-12-20) "temporary implication"
56 ------------------------------------------
58 Lots of fixes and improvements all over the place, and a major overhaul
61 - Audiod improvements and fixes.
62 - Buffer tree robustness improvements.
63 - Cleanup of the mood subsystem.
64 - Fixes and cleanups for the flac decoder.
65 - Latency improvements for the ogg/opus decoder.
66 - Crypto support is now optional. On systems without
67 openssl/gcrypt, the build succeeds but para_server,
68 para_audiod, para_client won't be built.
69 - The build system now works for cross-compile setups.
70 - The dependency tree has been flattened, which speeds up
71 builds and avoids to recreate the man pages on every change.
72 - The error code helper has been rewritten from perl to C,
73 which further improves build time.
74 - Many small bugs in the build system have been identified

81 0.5.0 (2013-08-23) "invertible validity"
82 ----------------------------------------
84 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
86 - The sideband compatibility code has been removed, hence
87 sideband connections (introduced in 0.4.11) are now mandatory.
88 - Addblob commands can produce output.
89 - The stat command no longer sends garbage when para_server was
90 compiled against libgcrypt.
91 - Dependencies for gengetopt files are computed automatically.
92 This eliminates a constant source of build bugs.
93 - The setatt command now accepts file name patterns rather than only
95 - overview.pdf is now based on dia, a simple diagram creation program.
96 The new version is much more detailed and contains descriptions of
97 the various programs of the paraslash package.
98 - The separator of all multi-word options has been changed from
99 underscore to dash. For example --log_color becomes --log-color.
100 - Overhauled web pages and the new logo.

106 0.4.13 (2013-07-29) "spectral gravity"
107 --------------------------------------
109 One more 0.4.x release before the API-breaking changes for 0.5.0 go
110 in. The main features of this release are the ogg/opus audio format,
111 and UTF-8 support, but it includes also tons of other improvements
112 and fixes all over the place.
114 - New audio format: ogg/opus.
115 - UTF8 support for para_gui and the mp3 audio format handler.
116 - Scheduler improvements and fixes.
117 - The obsolete gettimeofday() function has been replaced
118 by clock_gettime() on systems which support it.
119 - Speed and usability improvements for para_gui.
120 - para_client now restores the fd flags of stdin and stdout
122 - Improved manual pages.
123 - Consistent version strings for all executables.
124 - Reduced dependencies on generated files result in fewer
125 recompilations on changes.
126 - Performance improvements for the compress filter.
127 - Improved downloads web page.
129 -----------------------------------------
130 0.4.12 (2012-12-20) "volatile relativity"
131 -----------------------------------------
132 The new command line player, the resample filter, ALSA support for
133 para_fade, and the improved build system are the highlights of this
134 release which probably marks the end of the 0.4.x series.
136 - The afh receiver and the para_play executable.
137 - The resample filter: A sample rate converter based on
139 - The "versions" directory has been removed from the master
140 branch. The tarballs of the old releases are now available
141 in the new "releases" branch.
142 - Overhaul of the build system: All generated files are now
143 written to the "build" directory.
144 - The modular mixer API and the alsa mixer.
145 - Minor fixes for the osx writer.
147 --------------------------------------
148 0.4.11 (2012-07-20) "mutual diversity"
149 --------------------------------------
151 The major feature in this release is the new sideband API for
152 client-server communication. This API will be used exclusively starting
153 with 0.5.0, which breaks backward compatibility but allows to get rid
154 of quite some compatibility code. Other noteworthy changes include
155 decoder latency improvements and a long-standing bug fix for the
158 - Sideband connections: If both para_server and para_client
159 support this feature, data is sent as a multiplexed stream.
160 - The --no_default_filters option of para_filter has been
162 - Several fixes and latency improvements to various decoders.
163 - The ALSA writer now limits the prebuffer time to 500ms.
164 - Documentation improvements.
165 - Overhaul of the command_util.sh script.
166 - Fixes for some minor problems found by the clang analyzer.
167 - Compiles (almost) without warnings on gcc-3.
168 - Robustness improvements of the buffer tree code.
170 ------------------------------------------
171 0.4.10 (2012-03-30) "heterogeneous vacuum"
172 ------------------------------------------
174 Nothing earth-shaking in this release, but quite a few usability
175 improvements and the usual mix of cleanups and fixes.
177 - The --no_default_filters option of para_filter has been
178 deprecated. It still works but has no effect and will be
179 removed in the next version.
180 - para_gui now prints also the stderr output of the executing
181 command in the bottom window.
182 - Cleanup and consolidation of the various wrappers for
183 write(), writev(), send() and friends.
184 - The obscure error messages on mmap() failures have been
185 replaced by meaningful messages. This affects mainly
187 - para_audioc: Cleanups and memory leak fixes.
188 - Test 0004-server no longer fails if para_server is not
190 - New configure options: --with-id3tag-{headers,libs}.
192 -------------------------------------
193 0.4.9 (2011-12-06) "hybrid causality"
194 -------------------------------------
196 Support for another audio format, interactive mode for para_client
197 and para_audiod and many small improvements/fixes all over the place.
199 - Support for flac, the free lossless audio codec.
200 - Fix for an endless loop in the mp3 decoder for certain
202 - When executed without specifying a command, para_client
203 and para_audioc start an interactive shell (requires
204 libreadline being installed). The interactive mode offers
205 full tab completion and command line history.
206 - autogen.sh now detects a distcc setup and adjusts the
207 parameter for the -j option of make accordingly.
208 - Shared memory areas are no longer restricted to 64K. We now
209 detect the maximal size of a shared memory area at runtime.
210 - cleanup of the internal uptime API.
211 - para_server prefaults the mmapped audio file to avoid
212 delays on slow media.
213 - A new test for the test-suite that exercises the
214 communication between para_server and para_audiod.
215 - The alsa writer eats up less CPU cycles when configured to
217 - Simplified and unified receiver code.
219 - Commands which print a list of matching audio files now
220 emit a meaningful error message if no audio file matched the
223 --------------------------------------
224 0.4.8 (2011-08-19) "nested assignment"
225 --------------------------------------
227 Gcrypt support, the overhauled osx writer and regex format specifiers
228 are the highlights of this release.
230 - support for libgcrypt as a drop-in replacement for openssl.
231 Run configure --enable-cryptolib=gcrypt to link against
232 libgcrypt. The two crypto implementations are compatible to
233 each other, i.e. a para_client executable linked against
234 gcrypt can connect to para_server linked against libssl
236 - Rewrite of the osx writer (output plugin for Mac OS).
237 - audiod: The format specifier for receivers, filters and
238 writers is now treated as a regular expression. This allows
239 to replace 5 lines in the config file (one for each audio
240 format) by one single line. See the manual for details.
241 - The *.cmdline.[ch] files are no longer contained in the released
242 tarballs. This reduces the size of the tarballs but requires
243 gengetopt to build the tarball.
244 - Compiles cleanly also with llvm/clang.
245 - Corrupt mp3 files are handled more gracefully.
246 - The alsa writer uses poll fds instead of computing timeouts.
247 - Cleanup of the generic writer API.
248 - sched: Optimized zero timeouts.
249 - vss timeout cleanups.
250 - oggdec fixes and improvements.
252 --------------------------------------
253 0.4.7 (2011-06-01) "infinite rollback"
254 --------------------------------------
256 The new ao writer, support for ssh RSA keys and a couple of other
259 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
260 platforms through the libao audio library.
261 - Support for RSA keys generated with ssh-keygen.
262 - configure: improved options for ogg/vorbis/speex.
263 - The git version reported by --version always matches HEAD.
264 - The autogen script detects the number of processors and
265 runs a parallel make if possible.
266 - Major cleanup of the crypto API.
267 - Documentation updates.
269 ------------------------------------------
270 0.4.6 (2011-03-31) "deterministic entropy"
271 ------------------------------------------
273 Lots of ogg/vorbis improvements, the new test suite, enhancements
274 for para_gui and a fair amount of other bug fixes.
276 - For DCCP/OGG streams the audio file header is only sent once
277 at the beginning of the stream rather than periodically
278 every five seconds. This reduces network traffic and the
280 - The vorbis comment header is replaced by an empty dummy header
281 before the header is sent over the network. This also results in
282 less network traffic and smaller FEC groups.
283 - The new "test" make target allows to perform some sanity checks prior
284 to installing the package.
285 - ogg timing fixes and performance improvements
286 - Scheduler improvements
287 - Proper exit codes for para_write
288 - para_gui: New option --theme to select a startup theme. Several
289 other improvements and fixes.
290 - aacdec error message cleanups
291 - simplified color error handling
293 --------------------------------------------
294 0.4.5 (2010-12-17) "symmetric randomization"
295 --------------------------------------------
297 Bug fixes, internal cleanups and variable-sized FEC slices.
299 - Contains a fix for an invalid-free-bug in the ogg audio format
301 - Switching off the DCCP sender works again.
302 - para_audiod handles crashes of para_server more robustly.
303 - Internal scheduler and writer cleanups.
304 - Reduced latency due to variable-sized FEC slices.
305 - Improved documentation and error diagnostics.
306 - The build of para_server is now optional, allowing the build
307 to succeed in case libosl is not installed.
309 ------------------------------------------
310 0.4.4 (2010-08-06) "persistent regularity"
311 ------------------------------------------
313 Support for yet another audio format, para_write improvements and
316 - Support for the speex codec.
317 - Support for sample formats other than 16 bit little endian.
318 - error2.h is now created by a perl script which speeds up configure
320 - Fix a bug in the aac decoder which could lead to segfaults in
321 para_filter/para_audiod.
322 - Fixes for autoconf-2.66.
324 ----------------------------------------
325 0.4.3 (2010-07-05) "imaginary radiation"
326 ----------------------------------------
328 Many improvements for the DCCP and the UDP transport, the new user
329 manual and the usual mix of bug fixes and internal improvements.
331 - FEC support for the DCCP sender (Gerrit Renker). The new
332 --dccp_max_slice_size, --dccp_data_slices_per_group and
333 --dccp_slices_per_group options can be used to set the FEC
334 parameters for the DCCP transport.
335 - DNS lookups for UDP targets (Gerrit Renker).
336 - The new user manual replaces the README, README.afs, REQUIREMENTS
337 and INSTALL documents.
338 - Fix an end-of-file detection bug in the oggdec filter.
339 - The new nonblock API.
340 - Both options of the oggdec filter have been removed.
341 - New debug mode for the internal scheduler.
343 ------------------------------------------
344 0.4.2 (2010-04-23) "associative expansion"
345 ------------------------------------------
347 It's been some time since the last release, but finally here is
348 paraslash-0.4.2. The bulk of the changes comes from the new buffer
349 tree API, but there are changes all over the tree. Mainly performance
350 and usability improvements, but also quite some bug fixes.
352 - The new buffer tree API.
353 - DCCP: Support for CCID negotiation (Gerrit Renker).
354 - UDP robustness fixes.
355 - The --bufsize option for mp3dec is gone as it no longer makes sense
356 for the new buffer tree API.
357 - Fix audible buffer underruns for wma streams.
358 - The alsa writer no longer prints meaningless underrun durations.
359 - audiod: Defaults work also for udp streams. If no filter is
360 given for an audio format that is received via upd, fecdec is
361 automatically added as the first filter (along with the decoder).
363 ---------------------------------------
364 0.4.1 (2009-12-22) "concurrent horizon"
365 ---------------------------------------
367 Support for another audio format, minor feature enhancements and lots of bug
368 fixes. All fixes that have been accumulated in the maint branch (in particular
369 those mentionened in the 0.3.6 release notes) appear in this release as well.
372 - new afh option: --human to activate human-readable output.
373 - new server/audiod option: --log-timing to print timing information.
374 - build system improvements.
375 - source code documentation updates.
377 -------------------------------------
378 0.3.6 (2009-12-07) "cubic continuity"
379 -------------------------------------
381 Quite a few bugs have been found and fixed since 0.3.5, so here's
382 another 0.3.x release. No new features.
384 - Always check return value of malloc().
385 - ogg vorbis/FEC: Do not write garbage after the audio file header.
386 - exit if root privileges could not be dropped.
387 - FEC: Fix computation of extra slices.
388 - oss: Fix check for empty input buffer.
389 - Avoid buffer underruns due to filter chain output buffer constraints.
390 - server: Fix assignment of afs_pid.
391 - Don't panic if the afs database contains unknown audio formats.
392 - http/dccp: Do not send the audio file header twice.
393 - FEC: Timing improvements.
395 ----------------------------------------------
396 0.4.0 (2009-11-10) "simultaneous independence"
397 ----------------------------------------------
399 Two significant changes which require the new version number: The
400 improved authentication dialog and the fact that the database code
401 has been moved to a library, libosl. To use the new version, you have
402 to generate new RSA keys, see INSTALL for details. A shell script is
403 provided for conversion of the 0.3 database to the new 0.4 format.
405 - stronger crypto for client authentication
406 - the database code has been moved to a library
407 - improved status item handling
408 - cleanup of the build system
409 - The "-V" option now also prints the git version
410 - the new parser-friendly listing mode for the ls and stat commands
411 - mandatory rc4 encryption
412 - major audio format handler cleanups
413 - (id3,...) tags are no longer stored as a combined string in the database
414 - new mood methods: artist_matches, title_matches, comment_matches,
415 album_matches, year_maches, year.
417 --------------------------------------------
418 0.3.5 (2009-09-21) "symplectic separability"
419 --------------------------------------------
421 Full client support for *BSD Unixes, complete re-write of the ogg
422 vorbis audio format handler, various improvements all over the place
423 and the usual mix of bugfixes. This release marks the end of the 0.3
424 series if no serious problems show up.
426 - the new oss writer (supported on *BSD and Linux)
427 - rewrite of the ogg vorbis audio format handler. It's
428 recommended to replace the chunk tables of existing ogg
429 vorbis files in the afs database by re-adding these files
431 - support for netmask subsets (Gerrit Renker)
432 - the new prebuffer filter
433 - improved signal handling
434 - variable fec output buffer size
435 - improved FEC timing fixes audible buffer underruns in UDP mode
436 - --log_color actually works
437 - new ls option: -d (print dates as seconds after the epoch)
438 - update to gengetopt 2.22.2
439 - support for RSA keys of size > 512 bits
440 - new option "mixer_channel" for para_fade
442 -----------------------------------------
443 0.3.4 (2009-05-07) "elliptic inheritance"
444 -----------------------------------------
446 The new udp sender, forward error correction, colored logs and various
447 other improvements. As the udp sender does not depend on any special
448 libraries, it is built unconditionally.
450 - The udp sender replaces the ortp sender. The new code uses forward
451 error correction to protect against packet losses. Many thanks to
452 Gerrit Renker for providing ipv6 support.
453 - The default port for udp streaming now defaults to 8000, like
454 for the http and the dccp senders/receivers.
455 - Loglevels are now specified as symbolic names, e.g.
457 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
458 - para_server/para_audiod: Color support for log messages.
459 - new options for mp3dec: --ignore-crc, --bufsize
460 - new audiod option: --config-file.
461 - gengetopt cleanups.
462 - Improved help/man pages: The documentation of para_audiod,
463 para_recv, para_filter and para_write now also contains
464 all options of the available receivers/filters/writers. The
465 man page of para_fade contains a description of the different
467 - More source code documentation.
470 --------------------------------------------
471 0.3.3 (2008-12-01) "axiomatic perspectivity"
472 --------------------------------------------
474 Internal code cleanups, bug fixes, improved tag handling and the new
475 amplification filter.
477 - para_server uses the generic scheduling code.
478 - overhaul of the virtual streaming system.
479 - mp3: id3 version 2 support via libid3tag (optional)
480 - ogg: vorbis comment support.
481 - aac meta info support.
482 - mp3 audio format handler cleanups.
483 - new filter: "amp" to amplify the amplitude of the audio stream
484 - new status item/database entry: amplification. It is
485 used by the amp filter to pre-amplify the audio stream.
486 - fix a close-without-open bug in para_write.
487 - fix a bug in com_init() which was introduced in 0.3.2.
488 - better error diagnostics for para_client.
490 -----------------------------------------
491 0.3.2 (2008-04-11) "probabilistic parity"
492 -----------------------------------------
494 The new para_afh executable, scheduling and documentation improvements.
496 - new ls option: -lc (list chunk table)
497 - new executable: para_afh, the stand-alone audio file handler tool
498 - afs commands can send output more than SHMMAX (32MB on Linux). This
499 also reduces the memory usage of commands that produce large amounts
501 - major scheduler and audiod cleanups.
502 - more detailed and much nicer man pages.
504 ---------------------------------------
505 0.3.1 (2008-02-23) "liquid interaction"
506 ---------------------------------------
508 A mix of cleanups, bug fixes, improvements, and some new features. No
509 significant changes to the new database (osl) code, which is generally
512 - Share some similar/duplicate code between the http and the
514 - Generic access control lists for paraslash senders.
515 - dccp sender: Access control lists, connection limiting and support
516 for the allow,deny,on,off,help sender commands.
517 - The default dccp port changed from 5001 to 8000 (suggested by
519 - para_server starts even if not all public keys could be loaded.
520 - Audiod performance improvements.
521 - fix a bug in the "off" command of the http sender.
522 - fix some fd and memory leaks.
523 - Update to gengetopt-2.22.
525 -------------------------------------
526 0.3.0 (2008-01-12) "solar saturation"
527 -------------------------------------
529 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
532 Usually one might expect lots of new features AND a big increase in size
533 for a major release like this.
535 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
536 ever. The decrease in size is mostly due to the removal of some
537 graphical tools (which were only quick hacks anyway). But also the
538 fact that the mysql code is gone cuts down the size a bit.
540 Being independent of mysql comes at a cost: The fact that paraslash
541 now contains its own database (the object storage layer, osl) increases
542 the (stripped) binary size of para_server by ~50K on i386.
544 - no more restrictions on unique basenames.
545 - independent of mysql: The new self-contained object
546 storage layer (osl) replaces the mysql database.
547 - New executable para_fsck: Check integrity of osl tables.
549 - Reliable audio file move/rename detection.
550 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
551 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
553 - the new osl-based audio file selector (afs) replaces the random,
554 the playlist and the mysql selector of paraslash-0.2.x.
555 - IPv6 support (thanks to Gerrit Renker).
556 - paraslash-0.2.x streams are now called "moods". Writing
557 0.3.x-mood definitions should be both easier and more
558 powerful than writing 0.2.x-stream definitions.
559 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
560 been removed. The world is a better place without them. However,
561 para_gui is still there.
562 - afs tracks audio file selection also in playlist mode.
563 - few easy-to-use afs commands replace the many not-so-easy-to-use
564 mysql commands (and are available also in playlist mode).
565 - Improved error subsystem.
566 - The earth-shaking new logo.
568 -----------------------------------------
569 0.2.17 (2007-11-20) "isotropic threshold"
570 -----------------------------------------
572 Mainly bugfixes and cleanups in this version which marks the end of
573 the 0.2.x series if no serious bugs show up after the release.
575 - mysql_selector: fix a locking bug.
576 - universal chunk queueing.
577 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
579 - be more carful wrt. signed vs. unsigned argument passing.
580 - cleanup error.h and fix some references to invalid error
582 - update to gengetopt-2.21.
583 - update to ortp-0.13.1.
584 - autoconf: extend checks for headers, library functions and
585 compiler characteristics.
586 - Fix streaming of large mp3 files.
587 - Fix an off-by-one bug in playlist handling.
589 --------------------------------------
590 0.2.16 (2007-04-05) "neural discharge"
591 --------------------------------------
593 The main change in this release is the major audio format handler
594 cleanup which removes some similar/duplicate code and makes it easier
595 to implement plugins for other audio formats. Of course, the usual mix
596 of other improvements/changes/bugfixes also made it into the release.
598 - simplified audio format handlers (most of the handling functions
599 were moved one layer up to the virtual streaming system).
600 - para_server uses mmap to read audio files
601 - repositioning of mp3 streams is much faster, in particular for
602 jumping near the end of large mp3 files.
603 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
605 - fix a bug in para_filter that caused decoding of aac files
606 to start only after a few seconds.
607 - fix osx_writer hangs
608 - simplified dccp code (thanks to Gerrit Renker)
609 - the compress filter works also on big endian systems (ppc)
611 -----------------------------------------
612 0.2.15 (2007-02-16) "inductive resonance"
613 -----------------------------------------
615 Minor improvements, more documentation and a bunch of bug fixes.
617 - para_server: The server.users file is only read once on server
618 startup rather than for each connection
619 - mp3dec: Fix decoding of corrupt mp3 files
620 - afs (audio file sender) is now called vss (virtual streaming
621 system). Consequently, the permission flags specified in
622 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
623 become VSS_READ and VSS_WRITE respectively.
624 - para_audiod/para_filter: Fix a bug that caused the last chunk
625 of audio data not being written under certain circumstances
626 - audiod: compute the difference of server time and local time
628 - para_server/para_audiod: Fix some memory leaks
629 - documentation improvements
630 - configure.ac: fix checks for para_krell
633 -------------------------------------------
634 0.2.14 (2006-10-15) "transient singularity"
635 -------------------------------------------
637 The only major enhancement of this version is the osx writer which completes
638 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
639 until now for reasons beyond the scope of this changelog entry.
641 - new output plugin for Mac Os: the osx writer
642 - rename configure command line options from --enable-xxx-headers to
643 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
644 - configure: new command line options: --with-mad-headers,
645 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
646 - some robustness fixes
647 - dymamic audio format recognition for audiod
648 - para_server: new command line option: --autoplay_delay
649 - para_audiod: new command line option: --clock_diff_count
651 ---------------------------------------
652 0.2.13 (2006-07-14) "sonic convolution"
653 ---------------------------------------
655 A bunch of new features and core changes.
657 - the new paraslash scheduler, short and sweet.
658 - Support for m4a/mp4 files via the new aac audio format
659 handler/filter (requires libfaad).
660 - each writer has its own command line parser, just like
661 para_recv and para_filter.
662 - para_client and para_audioc use the error subsystem
663 - writers are integrated in para_audiod (currently linux-only)
664 - para_client is integrated in para_audiod
665 - random/playlist selector: improved info strings
666 - new audiod commands: tasks, kill
667 - update to libortp-0.10.1
668 - para_fade: wake time defaults to 8 hours from now
669 - update to autoconf-2.60
671 ------------------------------------------
672 0.2.12 (2006-05-12) "oriented abstraction"
673 ------------------------------------------
675 Many user-visible changes in this release and lots of new
679 - the new optional dccp sender/receiver. It uses the datagram
680 congestion control protocol. You'll need a fairly new kernel
682 - paraslash works on Mac OS X (thanks to Gerd Becker)
683 - para_play renamed to para_write
684 - modular output plugin design (writers) for para_write
685 - new file_writer output plugin for para_write
686 - compress filter speed improvements
687 - update to libortp-0.9.1
688 - update to gengetopt-2.17rc
689 - para_client no longer depends on libreadline (as the
690 code for the interactive mode was removed).
691 - gcc-2-95 is no longer a supported compiler. It may still
692 work, but it gets no more testing.
693 - the tarball no longer contains the screenshot images which
694 reduces its size quite a bit.
695 - configure: new command line options: --enable-mysql-headers
696 and --enable-mysql-libs
698 ------------------------------------
699 0.2.11 (2006-03-11) "atomic duality"
700 ------------------------------------
702 Here it is, the first paraslash release developed with git. There
703 are fairly many user-visible changes in this release. As two out of
704 the three "database tools" of paraslash don't use a database at all,
705 they are now called "audio file selectors" instead.
708 - the cdt command (change database tool) becomes chs (change
710 - no more colon separators: The syntax of some options of
711 para_audiod and para_filter have changed. Use --help for
712 more info (and some examples).
713 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
714 - switch from cvs to git (should've done that earlier)
715 - the new ipc subsystem
716 - new audio file selector: playlist
717 - para_server: the dopey selector is now called "random",
718 and is the default selector. Use the --selector option to
719 choose another selector at startup, or the chs command to
720 change the selector at runtime.
721 - X86_64 fixes (thanks to Steffen Klassert)
724 --------------------------------------
725 0.2.10 (2006-02-17) "cyclic attractor"
726 --------------------------------------
728 Huge documentation update, a scrollable window for para_gui, ortp
729 improvements, and of course many small fixes not mentioned here.
730 The diffstat below is rather misleading as most insertions are due
731 to the new source documentation.
734 - para_server also uses the new error subsystem
735 - lots of new documentation (UTSL)
737 - keysyms for cursor keys and for next/previous page keys
738 - scrollable output window
739 - new internal commands: scroll up/down, page up/down
740 - fix color of command output.
741 - ortp: the --chunk_time and --header flags are no longer needed
742 for para_recv/para_audiod as this information is now encoded in
743 each rtp packet sent by para_server.
745 -------------------------------------------
746 0.2.9 (2006-01-24) "progressive turbulence"
747 -------------------------------------------
749 Internal audiod receivers/filters, the new error subsystem and
750 a lot of small improvements.
752 - para_recv and para_filter are integrated into the para_audiod
753 binary, i.e. audiod no longer spawns a new process for
754 each receiver/filter. As para_recv and para_filter might be
755 useful as standalone programs, they still get built (linked
756 against the same object files that are also used for audiod).
757 - further ortp timing improvements should reduce the CPU usage
758 of the ortp receiver.
759 - improved audio grabbing. The 'grab' command of para_audiod
760 has its own set of command line options. Read the output of
761 "para_audioc help grab" for more info.
762 - oggdec: configurable input prebuffer size.
763 - the new error subsystem gives better error diagnostics
764 and reduces code size.
766 -----------------------------------------
767 0.2.8 (2006-01-02) "dynamic accumulation"
768 -----------------------------------------
770 The new modular filter design and the para_play-hangs bugfix.
772 - new executable: para_filter. It combines para_mp3dec,
773 para_oggdec and para_compress. It also adds a further filter
774 type, wav, that just inserts a wave header at the desired point
775 of the filter chain. All 'piping' is done in-memory (i.e. no
776 read/write operations are used).
777 - para_play: fix a stupid bug that caused it to hang under
778 certain circumstances.
780 -------------------------------------------
781 0.2.7 (2006-12-27) "transparent invariance"
782 -------------------------------------------
784 Not many user-visible changes but a fair amount of internal improvements.
787 - The http sender buffers data if it can not be sent
788 out immediately (because the socket is not writable). This
789 should prevent para_server from shutting down the connection
790 too early on a loaded network.
791 - para_play also prebuffers data if it is told to start at a
792 future time by the --start_time option.
793 - The return of para_recv: It combines para_ortp_recv and
794 para_http_recv. Use the --receiver option to switch between
795 the two. para_recv builds without libortp, but contains
796 only the http receiver in this case.
797 - update to ortp 0.8.1. As this ortp release contains incompatible
798 changes, para_recv-0.2.7 won't link against older ortp libs.
799 - improved ortp timings.
800 - use of gcc-extensions that #define away for non-gcc and
803 -------------------------------------------
804 0.2.6 (2005-10-29) "recursive compensation"
805 -------------------------------------------
807 Transparent session encryption (uses openssl's Alleged RC4 cipher),
808 the internal find command and several other improvements and cleanups.
810 - Encrypt the session if encryption is requested by the client
811 (default for para_client 0.2.6). This is backwards
812 compatible, so older clients can still connect to para_server
813 0.2.6. Use the new client option --plain to request an
814 uncrypted session (off by default, must be set to on in
815 order to connect to para_server 0.2.x with 0 <= x <= 5).
816 - para_server uses an internal function to locate audio files
817 rather than calling find(1). The server option
818 --mysql_audio_file_dir replaces --mysql_find_cmd.
819 - documentation update
821 - header file cleanup
822 - para_client code cleanup
823 - para_gui: faster display of output of display commands
825 ------------------------------------------
826 0.2.5 (2005-10-13) "aggressive resolution"
827 ------------------------------------------
829 This release adds internal senders, i.e. no more external programs are
830 spawned for sending out the audio data. There are two different senders
831 available: The http sender and the ortp sender (former para_send which
832 is no longer needed).
834 The new sender code has a plugin-like design so it can be easily
835 extended should there be be any future need for supporting another
836 network streaming protocol. All senders are completely independent of
837 each other. In particular, the http and the ortp sender can operate
840 - new server command: sender to control senders at runtime.
841 Read the output of "para_server -h" and "para_client help
842 sender" for more information.
843 - para_recv renamed to para_ortp_recv
844 - new executable: para_http_recv, a simple command line
846 - major afs/mp3/ogg code simplifications due to internal
848 - ogg timing improvements
849 - fix several minor memory leaks (found by valgrind)
850 - empty stream definitions work again
851 - com_ne(): ignore errors on remove
852 - audiod: fix segfault on server restart
854 ---------------------------------------
855 0.2.4 (2005-09-21) "toxic anticipation"
856 ---------------------------------------
858 Several small improvements, fixes and the new grab command.
861 - new command: "grab" to grab the output of the stream reader
862 or any filters. Read the output of "para_audioc help grab"
863 for more information.
866 - audioc: new command line option: --bufsize to specify a
867 buffer size different from the default size 8192.
868 - improved error diagnostics for para_play.
869 - new configure option: --enable-ssldir so search for openssl in
871 - sdl_gui: Make it look nice again for 1024x768
872 - server: report total size of memory allocated with sbrk by malloc,
873 new command line option: --announce_time
875 -----------------------------------------
876 0.2.3 (2005-09-01) "hydrophilic movement"
877 -----------------------------------------
879 Two new executables and major feature enhancements.
881 - audiod filters: It is now possible to specify arbitrary many
882 (including none) filters for each supported audio
883 format. This can be used e.g. for normalizing volume,
884 transforming or grabbing the audio stream, or for using
885 visualizers. Read the output of "para_audiod -h" for the
886 syntax of the new --filter_cmd option.
887 - new executable: para_play, a tiny alsa player. It
888 can play wave files or raw pcm (16 bit little endian)
890 - new executable: para_compress, a dynamic range compressor
891 intended to keep audio output at a consistent volume. Derived
892 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
893 - audiod: New option: --stream_delay. This can be used in
894 a local network to syncronize the audio output of all
895 clients that play the same stream.
897 ------------------------------------------
898 0.2.2 (2005-08-19) "tangential excitation"
899 ------------------------------------------
901 Mostly internal changes in this release, but also some new commands
902 for the mysql database tool.
904 - cleanup exec.c, fix para_exec bug
905 - compile time loglevel (log messages below the given level
906 won't be compiled in, which reduces the size of the
908 - new log macros that shorten the size of the source code.
909 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
910 to send only zeros. With this workaround, para_audioc works
912 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
913 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
914 (new entry), "snp" (set numplayed). Read the manual for more
917 ---------------------------------------
918 0.2.1 (2005-08-15) "surreal experience"
919 ---------------------------------------
921 Here comes paraslash-0.2.1. It contains a couple of new features and,
922 surprise, only minor bug fixes.
924 - kill noisy mp3 debug message
925 - cleanup of the build system
926 - para_server and para_client directly use the crypto routines
927 of the openssl library rather than invoking the openssl command
929 - server/audiod: new option --user to switch to the given user
930 when invoked as root. Read the output of "para_server -h" for
932 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
933 status. Default: "para_audioc stat"
934 - sdl_gui: new option --pic_cmd to be used to download the picture.
935 Default: "para_client pic"
936 - audiod: 5 slots ought to be enough for everybody
937 - audiod: new status item: Uptime, kill hup command
939 ------------------------------------------
940 0.2.0 (2005-08-06) "distributed diffusion"
941 ------------------------------------------
943 After several month of increased development activity, paraslash-0.2.0
944 has arrived. It contains many new features and is much more
945 self-contained than the old 0.1.x series. Enjoy!
948 - para_server: fix hang on song change and crash on sighup.
949 Speed up mysql queries. The DIR_LIKE macro is gone.
950 - new executables: para_audiod, the local audio daemon that
951 starts playback (uses SCM_CREDENTIALS socket magic) and
952 para_audioc, the corresponding client.
953 - new executables: para_mp3dec/para_oggdec, two really teensy
954 decoders. para_mp3dec is based on libmad, para_oggdec requires
956 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
957 they are now called para_send and para_recv respectively.
958 - documentation updates
959 - para_gui is themable. For now there is the default theme that
960 looks as before and the simple theme: blue and easy.
961 - gui: audio streaming is now handled by audiod. Time display shows
962 playback time rather than streaming time
963 - slider: update to libzmw-0.2.0
964 - para_krell: fix crash on server shutdown
965 - switch from gzip to bzip2
967 ----------------------------------------
968 0.1.7 (2005-04-18) "melting penetration"
969 ----------------------------------------
971 The main change in this release is clearly the oggvorbis rewrite,
972 but there are also lots of smaller changes. If you intend to use both
973 the mp3 and the ogg plugin, it is recommended to use software mixing,
974 e.g. the dmix plugin which is provided by ALSA.
976 - new executables: para_ovsend and para_ovrecv for sending/receiving
977 oggvorbis files via rtp. Requires the open rtp library. Get it at
978 http://www.linphone.org/ortp/
979 - rewrite of the ogg_vorbis core code
980 - configure detects libzmw and, if detected, includes
981 para_slider to the list of binaries to be built by make
982 - server stream writers read from their associated fifo rather
984 - slider: two new sliders, lastplayed and numplayed
985 - fix nasty double free bug which caused random segfaults in case of
986 mp3 files with invalid header information
987 - gui: new command line option: --stream_timeout=seconds to
988 deactivate a slot if it is idle for that many seconds (default=`5')
991 ---------------------------------------
992 0.1.6 (2005-03-05) "asymptotic balance"
993 ---------------------------------------
995 Only little user-visible changes in this release. Mainly bugfixes and
996 core code cleanup. This is probably the most stable version ever if you
999 - fix several memory leaks
1000 - rename default name of mysql database from "music" to "paraslash".
1001 Use para_server's --mysql_database option if you do not want to
1002 rename your old database.
1003 - rework ogg vorbis code
1004 - make update command work on mysql servers with LOCAL_INFILE
1006 - gui: improved stream I/O (slots)
1007 - simplified audio format API
1008 - para_pob_ogg is gone
1010 ------------------------------------
1011 0.1.5 (2004-12-31) "opaque eternity"
1012 ------------------------------------
1014 Let's slide gently into the new year.
1016 - new: para_slider (not built automatically, type "make
1017 para_slider" to build). A toy for those who always felt that
1018 creating stream definitions is difficult. See screenshots,
1019 README and FEATURES for more info.
1020 - improved signal handling. Fixes server segfault on SIGHUP
1021 for linux kernels newer than Aug 24 2004 and makes para_gui
1023 - reload database tool on SIGHUP
1024 - improved help message for sl
1025 - do not log "broken pipe" messages as errors. They are
1027 - fix wrong error message on permission errors
1029 -----------------------------------------
1030 0.1.4 (2004-12-19) "tunneling transition"
1031 -----------------------------------------
1033 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1034 Hopefully, most of them got wiped out with this release. Some
1035 enhancements went also in.
1037 - improved error diagnostics for all commands
1038 - stradd/picadd: overwrite previous contents if entry already
1039 exists, rather than returning errors
1040 - stradd: use current stream if invoked without args
1041 - faster (and hopefully more stable) ogg-vorbis handling
1042 - para_krell: reap children to avoid zombie-flooding in case
1043 no server is running
1044 - si: report also server pid
1045 - server: don't busy-loop if dbtool reports only invalid files.
1046 - gui: CTRL+C works again, fix stream_read command line option
1048 - fix mysql dbtool startup in case no database exists
1049 - many small fixes and cleanups
1051 ---------------------------------------
1052 0.1.3: (2004-12-10) "vanishing inertia"
1053 ---------------------------------------
1055 Starting from this release, the database tools are integrated in the
1056 server binary. This decreases server startup time, reduces code size
1057 and speeds up database commands. However, the layout of the underlying
1058 mysql database changed only slightly and 0.1.3 should be backwards
1059 compatible in that respect.
1063 - If mysql is not detected at compile time, or fails to init
1064 at runtime, fall back to the dopey database tool which should
1066 - para_dbtool and dbtool.conf are gone. All mysql specific
1067 options are read from server.conf and are prefixed by 'mysql_'.
1068 - new command: cdt (change database tool)
1069 - new command line option: dbtool (choose startup database tool)
1070 - The name of current stream is now stored in the database,
1071 so paraslash remembers its current stream when restarted.
1072 - new command: csp (change stream and play)
1073 - para_gui also reports current database tool and server uptime
1075 -------------------------------------------
1076 0.1.2: (2004-11-28) "spherical fluctuation"
1077 -------------------------------------------
1079 Point release before the big dbtool changes go in.
1081 - dbtool: rename ca to cam (copy all meta data). It now also
1082 copies numplayed and lastplayed time as well as the picture
1084 - fix endless-loop-bug caused by mp3 files with invalid header
1086 -----------------------------------------
1087 0.1.1: (2004-11-05) "floating atmosphere"
1088 -----------------------------------------
1091 - new dbtool command: mbox. Browse your sound-file collection
1092 with your favorite mail reader.
1093 - several small fixes
1095 -------------------------------------
1096 0.1.0: (2004-10-22) "rotating cortex"
1097 -------------------------------------
1099 - fix logging bug for loglevel > VERBOSE
1101 - correct timings for vbr mp3s
1102 - modular audio format support
1103 - ogg-vorbis support (experimental)
1104 - new server option: autoplay
1106 -----------------------------------------
1107 0.0.99: (2004-07-25) "harmonic deviation"
1108 -----------------------------------------
1110 - rename projectname from icc to paraslash (play, archive, rate
1111 and stream large audio sets happily)
1112 - paraslash is no longer restricted to one particular audio
1114 - new dbtool commands (stradd, strq, strdel) for easy stream
1115 managment w/o configuration file. That obsoletes stream_defs
1116 file/config option for dbtool.
1117 - picadd accepts jpeg data from stdin
1118 - new server commands: ps (select previous stream), sc (song change)
1119 - new default pictures for sdl_gui
1120 - gui: new key_map option for binding commands and internal
1121 functions to arbitrary keys, nice help screen, rip out
1122 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1123 show silly logo on startup
1124 - new executables: para_fade for fading volume, para_dbadm for
1125 manipulating attributes
1126 - cdb adds _all_ tables to mysql database
1127 - revised and beautified documentation
1128 - sample dbtool rewritten in C
1131 ---------------------------------------------
1132 0.0.98: (2003-12-26) "incremental smoothness"
1133 ---------------------------------------------
1135 - kick icecast in favour of poc. That removes some races and reduces
1136 core code considerably.
1137 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1138 give finer info on afs' status.
1139 - gui can start decoder (see config options). Further new gui
1140 commands: refresh (^L), jmp (F1-F10)
1141 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1142 terminates gui. This fixes dead instances consuming memory
1144 - new dbtool command: verb for sending verbatim sql queries.
1145 - fix pid_list races (by removing pid_list)
1148 --------------------
1149 0.0.97: (2003-10-26)
1150 --------------------
1152 - installation prefix now defaults to /usr/local
1153 - new commands for gui: snozze, sleep and reread config
1154 - config file for gui and sdl_gui
1155 - fix problems with filenames containing funny characters
1156 (reported by Thomas Forell)
1157 - improved signal handling for gui, now it rereads conf on SIGHUP
