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

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

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

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

115 --------------------------------------
116 0.4.13 (2013-07-29) "spectral gravity"
117 --------------------------------------
118
119 One more 0.4.x release before the API-breaking changes for 0.5.0 go
120 in. The main features of this release are the ogg/opus audio format,
121 and UTF-8 support, but it includes also tons of other improvements
122 and fixes all over the place.
123
124 - New audio format: ogg/opus.
125 - UTF8 support for para_gui and the mp3 audio format handler.
126 - Scheduler improvements and fixes.
127 - The obsolete gettimeofday() function has been replaced
128 by clock_gettime() on systems which support it.
129 - Speed and usability improvements for para_gui.
130 - para_client now restores the fd flags of stdin and stdout
131 on shutdown.
132 - Improved manual pages.
133 - Consistent version strings for all executables.
134 - Reduced dependencies on generated files result in fewer
135 recompilations on changes.
136 - Performance improvements for the compress filter.
137 - Improved downloads web page.
138
139 -----------------------------------------
140 0.4.12 (2012-12-20) "volatile relativity"
141 -----------------------------------------
142 The new command line player, the resample filter, ALSA support for
143 para_fade, and the improved build system are the highlights of this
144 release which probably marks the end of the 0.4.x series.
145
146 - The afh receiver and the para_play executable.
147 - The resample filter: A sample rate converter based on
148 libsamplerate.
149 - The "versions" directory has been removed from the master
150 branch. The tarballs of the old releases are now available
151 in the new "releases" branch.
152 - Overhaul of the build system: All generated files are now
153 written to the "build" directory.
154 - The modular mixer API and the alsa mixer.
155 - Minor fixes for the osx writer.
156
157 --------------------------------------
158 0.4.11 (2012-07-20) "mutual diversity"
159 --------------------------------------
160
161 The major feature in this release is the new sideband API for
162 client-server communication. This API will be used exclusively starting
163 with 0.5.0, which breaks backward compatibility but allows to get rid
164 of quite some compatibility code. Other noteworthy changes include
165 decoder latency improvements and a long-standing bug fix for the
166 ALSA writer.
167
168 - Sideband connections: If both para_server and para_client
169 support this feature, data is sent as a multiplexed stream.
170 - The --no_default_filters option of para_filter has been
171 removed.
172 - Several fixes and latency improvements to various decoders.
173 - The ALSA writer now limits the prebuffer time to 500ms.
174 - Documentation improvements.
175 - Overhaul of the command_util.sh script.
176 - Fixes for some minor problems found by the clang analyzer.
177 - Compiles (almost) without warnings on gcc-3.
178 - Robustness improvements of the buffer tree code.
179
180 ------------------------------------------
181 0.4.10 (2012-03-30) "heterogeneous vacuum"
182 ------------------------------------------
183
184 Nothing earth-shaking in this release, but quite a few usability
185 improvements and the usual mix of cleanups and fixes.
186
187 - The --no_default_filters option of para_filter has been
188 deprecated. It still works but has no effect and will be
189 removed in the next version.
190 - para_gui now prints also the stderr output of the executing
191 command in the bottom window.
192 - Cleanup and consolidation of the various wrappers for
193 write(), writev(), send() and friends.
194 - The obscure error messages on mmap() failures have been
195 replaced by meaningful messages. This affects mainly
196 para_afh.
197 - para_audioc: Cleanups and memory leak fixes.
198 - Test 0004-server no longer fails if para_server is not
199 being built.
200 - New configure options: --with-id3tag-{headers,libs}.
201
202 -------------------------------------
203 0.4.9 (2011-12-06) "hybrid causality"
204 -------------------------------------
205
206 Support for another audio format, interactive mode for para_client
207 and para_audiod and many small improvements/fixes all over the place.
208
209 - Support for flac, the free lossless audio codec.
210 - Fix for an endless loop in the mp3 decoder for certain
211 (corrupt) mp3 files.
212 - When executed without specifying a command, para_client
213 and para_audioc start an interactive shell (requires
214 libreadline being installed). The interactive mode offers
215 full tab completion and command line history.
216 - autogen.sh now detects a distcc setup and adjusts the
217 parameter for the -j option of make accordingly.
218 - Shared memory areas are no longer restricted to 64K. We now
219 detect the maximal size of a shared memory area at runtime.
220 - cleanup of the internal uptime API.
221 - para_server prefaults the mmapped audio file to avoid
222 delays on slow media.
223 - A new test for the test-suite that exercises the
224 communication between para_server and para_audiod.
225 - The alsa writer eats up less CPU cycles when configured to
226 use the DMIX plugin.
227 - Simplified and unified receiver code.
228 - Makefile cleanups.
229 - Commands which print a list of matching audio files now
230 emit a meaningful error message if no audio file matched the
231 given pattern(s).
232
233 --------------------------------------
234 0.4.8 (2011-08-19) "nested assignment"
235 --------------------------------------
236
237 Gcrypt support, the overhauled osx writer and regex format specifiers
238 are the highlights of this release.
239
240 - support for libgcrypt as a drop-in replacement for openssl.
241 Run configure --enable-cryptolib=gcrypt to link against
242 libgcrypt. The two crypto implementations are compatible to
243 each other, i.e. a para_client executable linked against
244 gcrypt can connect to para_server linked against libssl
245 and vice versa.
246 - Rewrite of the osx writer (output plugin for Mac OS).
247 - audiod: The format specifier for receivers, filters and
248 writers is now treated as a regular expression. This allows
249 to replace 5 lines in the config file (one for each audio
250 format) by one single line. See the manual for details.
251 - The *.cmdline.[ch] files are no longer contained in the released
252 tarballs. This reduces the size of the tarballs but requires
253 gengetopt to build the tarball.
254 - Compiles cleanly also with llvm/clang.
255 - Corrupt mp3 files are handled more gracefully.
256 - The alsa writer uses poll fds instead of computing timeouts.
257 - Cleanup of the generic writer API.
258 - sched: Optimized zero timeouts.
259 - vss timeout cleanups.
260 - oggdec fixes and improvements.
261
262 --------------------------------------
263 0.4.7 (2011-06-01) "infinite rollback"
264 --------------------------------------
265
266 The new ao writer, support for ssh RSA keys and a couple of other
267 enhancements.
268
269 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
270 platforms through the libao audio library.
271 - Support for RSA keys generated with ssh-keygen.
272 - configure: improved options for ogg/vorbis/speex.
273 - The git version reported by --version always matches HEAD.
274 - The autogen script detects the number of processors and
275 runs a parallel make if possible.
276 - Major cleanup of the crypto API.
277 - Documentation updates.
278
279 ------------------------------------------
280 0.4.6 (2011-03-31) "deterministic entropy"
281 ------------------------------------------
282
283 Lots of ogg/vorbis improvements, the new test suite, enhancements
284 for para_gui and a fair amount of other bug fixes.
285
286 - For DCCP/OGG streams the audio file header is only sent once
287 at the beginning of the stream rather than periodically
288 every five seconds. This reduces network traffic and the
289 FEC group size.
290 - The vorbis comment header is replaced by an empty dummy header
291 before the header is sent over the network. This also results in
292 less network traffic and smaller FEC groups.
293 - The new "test" make target allows to perform some sanity checks prior
294 to installing the package.
295 - ogg timing fixes and performance improvements
296 - Scheduler improvements
297 - Proper exit codes for para_write
298 - para_gui: New option --theme to select a startup theme. Several
299 other improvements and fixes.
300 - aacdec error message cleanups
301 - simplified color error handling
302
303 --------------------------------------------
304 0.4.5 (2010-12-17) "symmetric randomization"
305 --------------------------------------------
306
307 Bug fixes, internal cleanups and variable-sized FEC slices.
308
309 - Contains a fix for an invalid-free-bug in the ogg audio format
310 handler code.
311 - Switching off the DCCP sender works again.
312 - para_audiod handles crashes of para_server more robustly.
313 - Internal scheduler and writer cleanups.
314 - Reduced latency due to variable-sized FEC slices.
315 - Improved documentation and error diagnostics.
316 - The build of para_server is now optional, allowing the build
317 to succeed in case libosl is not installed.
318
319 ------------------------------------------
320 0.4.4 (2010-08-06) "persistent regularity"
321 ------------------------------------------
322
323 Support for yet another audio format, para_write improvements and
324 bug fixes.
325
326 - Support for the speex codec.
327 - Support for sample formats other than 16 bit little endian.
328 - error2.h is now created by a perl script which speeds up configure
329 considerably.
330 - Fix a bug in the aac decoder which could lead to segfaults in
331 para_filter/para_audiod.
332 - Fixes for autoconf-2.66.
333
334 ----------------------------------------
335 0.4.3 (2010-07-05) "imaginary radiation"
336 ----------------------------------------
337
338 Many improvements for the DCCP and the UDP transport, the new user
339 manual and the usual mix of bug fixes and internal improvements.
340
341 - FEC support for the DCCP sender (Gerrit Renker). The new
342 --dccp_max_slice_size, --dccp_data_slices_per_group and
343 --dccp_slices_per_group options can be used to set the FEC
344 parameters for the DCCP transport.
345 - DNS lookups for UDP targets (Gerrit Renker).
346 - The new user manual replaces the README, README.afs, REQUIREMENTS
347 and INSTALL documents.
348 - Fix an end-of-file detection bug in the oggdec filter.
349 - The new nonblock API.
350 - Both options of the oggdec filter have been removed.
351 - New debug mode for the internal scheduler.
352
353 ------------------------------------------
354 0.4.2 (2010-04-23) "associative expansion"
355 ------------------------------------------
356
357 It's been some time since the last release, but finally here is
358 paraslash-0.4.2. The bulk of the changes comes from the new buffer
359 tree API, but there are changes all over the tree. Mainly performance
360 and usability improvements, but also quite some bug fixes.
361
362 - The new buffer tree API.
363 - DCCP: Support for CCID negotiation (Gerrit Renker).
364 - UDP robustness fixes.
365 - The --bufsize option for mp3dec is gone as it no longer makes sense
366 for the new buffer tree API.
367 - Fix audible buffer underruns for wma streams.
368 - The alsa writer no longer prints meaningless underrun durations.
369 - audiod: Defaults work also for udp streams. If no filter is
370 given for an audio format that is received via upd, fecdec is
371 automatically added as the first filter (along with the decoder).
372
373 ---------------------------------------
374 0.4.1 (2009-12-22) "concurrent horizon"
375 ---------------------------------------
376
377 Support for another audio format, minor feature enhancements and lots of bug
378 fixes. All fixes that have been accumulated in the maint branch (in particular
379 those mentionened in the 0.3.6 release notes) appear in this release as well.
380
381 - wma support.
382 - new afh option: --human to activate human-readable output.
383 - new server/audiod option: --log-timing to print timing information.
384 - build system improvements.
385 - source code documentation updates.
386
387 -------------------------------------
388 0.3.6 (2009-12-07) "cubic continuity"
389 -------------------------------------
390
391 Quite a few bugs have been found and fixed since 0.3.5, so here's
392 another 0.3.x release. No new features.
393
394 - Always check return value of malloc().
395 - ogg vorbis/FEC: Do not write garbage after the audio file header.
396 - exit if root privileges could not be dropped.
397 - FEC: Fix computation of extra slices.
398 - oss: Fix check for empty input buffer.
399 - Avoid buffer underruns due to filter chain output buffer constraints.
400 - server: Fix assignment of afs_pid.
401 - Don't panic if the afs database contains unknown audio formats.
402 - http/dccp: Do not send the audio file header twice.
403 - FEC: Timing improvements.
404
405 ----------------------------------------------
406 0.4.0 (2009-11-10) "simultaneous independence"
407 ----------------------------------------------
408
409 Two significant changes which require the new version number: The
410 improved authentication dialog and the fact that the database code
411 has been moved to a library, libosl. To use the new version, you have
412 to generate new RSA keys, see INSTALL for details. A shell script is
413 provided for conversion of the 0.3 database to the new 0.4 format.
414
415 - stronger crypto for client authentication
416 - the database code has been moved to a library
417 - improved status item handling
418 - cleanup of the build system
419 - The "-V" option now also prints the git version
420 - the new parser-friendly listing mode for the ls and stat commands
421 - mandatory rc4 encryption
422 - major audio format handler cleanups
423 - (id3,...) tags are no longer stored as a combined string in the database
424 - new mood methods: artist_matches, title_matches, comment_matches,
425 album_matches, year_maches, year.
426
427 --------------------------------------------
428 0.3.5 (2009-09-21) "symplectic separability"
429 --------------------------------------------
430
431 Full client support for *BSD Unixes, complete re-write of the ogg
432 vorbis audio format handler, various improvements all over the place
433 and the usual mix of bugfixes. This release marks the end of the 0.3
434 series if no serious problems show up.
435
436 - the new oss writer (supported on *BSD and Linux)
437 - rewrite of the ogg vorbis audio format handler. It's
438 recommended to replace the chunk tables of existing ogg
439 vorbis files in the afs database by re-adding these files
440 with "add -f".
441 - support for netmask subsets (Gerrit Renker)
442 - the new prebuffer filter
443 - improved signal handling
444 - variable fec output buffer size
445 - improved FEC timing fixes audible buffer underruns in UDP mode
446 - --log_color actually works
447 - new ls option: -d (print dates as seconds after the epoch)
448 - update to gengetopt 2.22.2
449 - support for RSA keys of size > 512 bits
450 - new option "mixer_channel" for para_fade
451
452 -----------------------------------------
453 0.3.4 (2009-05-07) "elliptic inheritance"
454 -----------------------------------------
455
456 The new udp sender, forward error correction, colored logs and various
457 other improvements. As the udp sender does not depend on any special
458 libraries, it is built unconditionally.
459
460 - The udp sender replaces the ortp sender. The new code uses forward
461 error correction to protect against packet losses. Many thanks to
462 Gerrit Renker for providing ipv6 support.
463 - The default port for udp streaming now defaults to 8000, like
464 for the http and the dccp senders/receivers.
465 - Loglevels are now specified as symbolic names, e.g.
466 "--loglevel info".
467 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
468 - para_server/para_audiod: Color support for log messages.
469 - new options for mp3dec: --ignore-crc, --bufsize
470 - new audiod option: --config-file.
471 - gengetopt cleanups.
472 - Improved help/man pages: The documentation of para_audiod,
473 para_recv, para_filter and para_write now also contains
474 all options of the available receivers/filters/writers. The
475 man page of para_fade contains a description of the different
476 modes of operation.
477 - More source code documentation.
478 - vss timing fixes.
479
480 --------------------------------------------
481 0.3.3 (2008-12-01) "axiomatic perspectivity"
482 --------------------------------------------
483
484 Internal code cleanups, bug fixes, improved tag handling and the new
485 amplification filter.
486
487 - para_server uses the generic scheduling code.
488 - overhaul of the virtual streaming system.
489 - mp3: id3 version 2 support via libid3tag (optional)
490 - ogg: vorbis comment support.
491 - aac meta info support.
492 - mp3 audio format handler cleanups.
493 - new filter: "amp" to amplify the amplitude of the audio stream
494 - new status item/database entry: amplification. It is
495 used by the amp filter to pre-amplify the audio stream.
496 - fix a close-without-open bug in para_write.
497 - fix a bug in com_init() which was introduced in 0.3.2.
498 - better error diagnostics for para_client.
499
500 -----------------------------------------
501 0.3.2 (2008-04-11) "probabilistic parity"
502 -----------------------------------------
503
504 The new para_afh executable, scheduling and documentation improvements.
505
506 - new ls option: -lc (list chunk table)
507 - new executable: para_afh, the stand-alone audio file handler tool
508 - afs commands can send output more than SHMMAX (32MB on Linux). This
509 also reduces the memory usage of commands that produce large amounts
510 of output.
511 - major scheduler and audiod cleanups.
512 - more detailed and much nicer man pages.
513
514 ---------------------------------------
515 0.3.1 (2008-02-23) "liquid interaction"
516 ---------------------------------------
517
518 A mix of cleanups, bug fixes, improvements, and some new features. No
519 significant changes to the new database (osl) code, which is generally
520 a good sign.
521
522 - Share some similar/duplicate code between the http and the
523 dccp sender.
524 - Generic access control lists for paraslash senders.
525 - dccp sender: Access control lists, connection limiting and support
526 for the allow,deny,on,off,help sender commands.
527 - The default dccp port changed from 5001 to 8000 (suggested by
528 Gerrit Renker).
529 - para_server starts even if not all public keys could be loaded.
530 - Audiod performance improvements.
531 - fix a bug in the "off" command of the http sender.
532 - fix some fd and memory leaks.
533 - Update to gengetopt-2.22.
534
535 -------------------------------------
536 0.3.0 (2008-01-12) "solar saturation"
537 -------------------------------------
538
539 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
540
541
542 Usually one might expect lots of new features AND a big increase in size
543 for a major release like this.
544
545 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
546 ever. The decrease in size is mostly due to the removal of some
547 graphical tools (which were only quick hacks anyway). But also the
548 fact that the mysql code is gone cuts down the size a bit.
549
550 Being independent of mysql comes at a cost: The fact that paraslash
551 now contains its own database (the object storage layer, osl) increases
552 the (stripped) binary size of para_server by ~50K on i386.
553
554 - no more restrictions on unique basenames.
555 - independent of mysql: The new self-contained object
556 storage layer (osl) replaces the mysql database.
557 - New executable para_fsck: Check integrity of osl tables.
558 - Lyrics support.
559 - Reliable audio file move/rename detection.
560 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
561 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
562 Solaris (sparc64).
563 - the new osl-based audio file selector (afs) replaces the random,
564 the playlist and the mysql selector of paraslash-0.2.x.
565 - IPv6 support (thanks to Gerrit Renker).
566 - paraslash-0.2.x streams are now called "moods". Writing
567 0.3.x-mood definitions should be both easier and more
568 powerful than writing 0.2.x-stream definitions.
569 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
570 been removed. The world is a better place without them. However,
571 para_gui is still there.
572 - afs tracks audio file selection also in playlist mode.
573 - few easy-to-use afs commands replace the many not-so-easy-to-use
574 mysql commands (and are available also in playlist mode).
575 - Improved error subsystem.
576 - The earth-shaking new logo.
577
578 -----------------------------------------
579 0.2.17 (2007-11-20) "isotropic threshold"
580 -----------------------------------------
581
582 Mainly bugfixes and cleanups in this version which marks the end of
583 the 0.2.x series if no serious bugs show up after the release.
584
585 - mysql_selector: fix a locking bug.
586 - universal chunk queueing.
587 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
588 to Gerrit Renker).
589 - be more carful wrt. signed vs. unsigned argument passing.
590 - cleanup error.h and fix some references to invalid error
591 codes.
592 - update to gengetopt-2.21.
593 - update to ortp-0.13.1.
594 - autoconf: extend checks for headers, library functions and
595 compiler characteristics.
596 - Fix streaming of large mp3 files.
597 - Fix an off-by-one bug in playlist handling.
598
599 --------------------------------------
600 0.2.16 (2007-04-05) "neural discharge"
601 --------------------------------------
602
603 The main change in this release is the major audio format handler
604 cleanup which removes some similar/duplicate code and makes it easier
605 to implement plugins for other audio formats. Of course, the usual mix
606 of other improvements/changes/bugfixes also made it into the release.
607
608 - simplified audio format handlers (most of the handling functions
609 were moved one layer up to the virtual streaming system).
610 - para_server uses mmap to read audio files
611 - repositioning of mp3 streams is much faster, in particular for
612 jumping near the end of large mp3 files.
613 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
614 and AFS_WRITE.
615 - fix a bug in para_filter that caused decoding of aac files
616 to start only after a few seconds.
617 - fix osx_writer hangs
618 - simplified dccp code (thanks to Gerrit Renker)
619 - the compress filter works also on big endian systems (ppc)
620
621 -----------------------------------------
622 0.2.15 (2007-02-16) "inductive resonance"
623 -----------------------------------------
624
625 Minor improvements, more documentation and a bunch of bug fixes.
626
627 - para_server: The server.users file is only read once on server
628 startup rather than for each connection
629 - mp3dec: Fix decoding of corrupt mp3 files
630 - afs (audio file sender) is now called vss (virtual streaming
631 system). Consequently, the permission flags specified in
632 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
633 become VSS_READ and VSS_WRITE respectively.
634 - para_audiod/para_filter: Fix a bug that caused the last chunk
635 of audio data not being written under certain circumstances
636 - audiod: compute the difference of server time and local time
637 correctly
638 - para_server/para_audiod: Fix some memory leaks
639 - documentation improvements
640 - configure.ac: fix checks for para_krell
641 - new man pages
642
643 -------------------------------------------
644 0.2.14 (2006-10-15) "transient singularity"
645 -------------------------------------------
646
647 The only major enhancement of this version is the osx writer which completes
648 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
649 until now for reasons beyond the scope of this changelog entry.
650
651 - new output plugin for Mac Os: the osx writer
652 - rename configure command line options from --enable-xxx-headers to
653 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
654 - configure: new command line options: --with-mad-headers,
655 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
656 - some robustness fixes
657 - dymamic audio format recognition for audiod
658 - para_server: new command line option: --autoplay_delay
659 - para_audiod: new command line option: --clock_diff_count
660
661 ---------------------------------------
662 0.2.13 (2006-07-14) "sonic convolution"
663 ---------------------------------------
664
665 A bunch of new features and core changes.
666
667 - the new paraslash scheduler, short and sweet.
668 - Support for m4a/mp4 files via the new aac audio format
669 handler/filter (requires libfaad).
670 - each writer has its own command line parser, just like
671 para_recv and para_filter.
672 - para_client and para_audioc use the error subsystem
673 - writers are integrated in para_audiod (currently linux-only)
674 - para_client is integrated in para_audiod
675 - random/playlist selector: improved info strings
676 - new audiod commands: tasks, kill
677 - update to libortp-0.10.1
678 - para_fade: wake time defaults to 8 hours from now
679 - update to autoconf-2.60
680
681 ------------------------------------------
682 0.2.12 (2006-05-12) "oriented abstraction"
683 ------------------------------------------
684
685 Many user-visible changes in this release and lots of new
686 features:
687
688
689 - the new optional dccp sender/receiver. It uses the datagram
690 congestion control protocol. You'll need a fairly new kernel
691 for this.
692 - paraslash works on Mac OS X (thanks to Gerd Becker)
693 - para_play renamed to para_write
694 - modular output plugin design (writers) for para_write
695 - new file_writer output plugin for para_write
696 - compress filter speed improvements
697 - update to libortp-0.9.1
698 - update to gengetopt-2.17rc
699 - para_client no longer depends on libreadline (as the
700 code for the interactive mode was removed).
701 - gcc-2-95 is no longer a supported compiler. It may still
702 work, but it gets no more testing.
703 - the tarball no longer contains the screenshot images which
704 reduces its size quite a bit.
705 - configure: new command line options: --enable-mysql-headers
706 and --enable-mysql-libs
707
708 ------------------------------------
709 0.2.11 (2006-03-11) "atomic duality"
710 ------------------------------------
711
712 Here it is, the first paraslash release developed with git. There
713 are fairly many user-visible changes in this release. As two out of
714 the three "database tools" of paraslash don't use a database at all,
715 they are now called "audio file selectors" instead.
716
717
718 - the cdt command (change database tool) becomes chs (change
719 selector)
720 - no more colon separators: The syntax of some options of
721 para_audiod and para_filter have changed. Use --help for
722 more info (and some examples).
723 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
724 - switch from cvs to git (should've done that earlier)
725 - the new ipc subsystem
726 - new audio file selector: playlist
727 - para_server: the dopey selector is now called "random",
728 and is the default selector. Use the --selector option to
729 choose another selector at startup, or the chs command to
730 change the selector at runtime.
731 - X86_64 fixes (thanks to Steffen Klassert)
732 - para_play fixes
733
734 --------------------------------------
735 0.2.10 (2006-02-17) "cyclic attractor"
736 --------------------------------------
737
738 Huge documentation update, a scrollable window for para_gui, ortp
739 improvements, and of course many small fixes not mentioned here.
740 The diffstat below is rather misleading as most insertions are due
741 to the new source documentation.
742
743 - autoconf cleanup
744 - para_server also uses the new error subsystem
745 - lots of new documentation (UTSL)
746 - gui improvements:
747 - keysyms for cursor keys and for next/previous page keys
748 - scrollable output window
749 - new internal commands: scroll up/down, page up/down
750 - fix color of command output.
751 - ortp: the --chunk_time and --header flags are no longer needed
752 for para_recv/para_audiod as this information is now encoded in
753 each rtp packet sent by para_server.
754
755 -------------------------------------------
756 0.2.9 (2006-01-24) "progressive turbulence"
757 -------------------------------------------
758
759 Internal audiod receivers/filters, the new error subsystem and
760 a lot of small improvements.
761
762 - para_recv and para_filter are integrated into the para_audiod
763 binary, i.e. audiod no longer spawns a new process for
764 each receiver/filter. As para_recv and para_filter might be
765 useful as standalone programs, they still get built (linked
766 against the same object files that are also used for audiod).
767 - further ortp timing improvements should reduce the CPU usage
768 of the ortp receiver.
769 - improved audio grabbing. The 'grab' command of para_audiod
770 has its own set of command line options. Read the output of
771 "para_audioc help grab" for more info.
772 - oggdec: configurable input prebuffer size.
773 - the new error subsystem gives better error diagnostics
774 and reduces code size.
775
776 -----------------------------------------
777 0.2.8 (2006-01-02) "dynamic accumulation"
778 -----------------------------------------
779
780 The new modular filter design and the para_play-hangs bugfix.
781
782 - new executable: para_filter. It combines para_mp3dec,
783 para_oggdec and para_compress. It also adds a further filter
784 type, wav, that just inserts a wave header at the desired point
785 of the filter chain. All 'piping' is done in-memory (i.e. no
786 read/write operations are used).
787 - para_play: fix a stupid bug that caused it to hang under
788 certain circumstances.
789
790 -------------------------------------------
791 0.2.7 (2006-12-27) "transparent invariance"
792 -------------------------------------------
793
794 Not many user-visible changes but a fair amount of internal improvements.
795
796
797 - The http sender buffers data if it can not be sent
798 out immediately (because the socket is not writable). This
799 should prevent para_server from shutting down the connection
800 too early on a loaded network.
801 - para_play also prebuffers data if it is told to start at a
802 future time by the --start_time option.
803 - The return of para_recv: It combines para_ortp_recv and
804 para_http_recv. Use the --receiver option to switch between
805 the two. para_recv builds without libortp, but contains
806 only the http receiver in this case.
807 - update to ortp 0.8.1. As this ortp release contains incompatible
808 changes, para_recv-0.2.7 won't link against older ortp libs.
809 - improved ortp timings.
810 - use of gcc-extensions that #define away for non-gcc and
811 gcc < 3.0.
812
813 -------------------------------------------
814 0.2.6 (2005-10-29) "recursive compensation"
815 -------------------------------------------
816
817 Transparent session encryption (uses openssl's Alleged RC4 cipher),
818 the internal find command and several other improvements and cleanups.
819
820 - Encrypt the session if encryption is requested by the client
821 (default for para_client 0.2.6). This is backwards
822 compatible, so older clients can still connect to para_server
823 0.2.6. Use the new client option --plain to request an
824 uncrypted session (off by default, must be set to on in
825 order to connect to para_server 0.2.x with 0 <= x <= 5).
826 - para_server uses an internal function to locate audio files
827 rather than calling find(1). The server option
828 --mysql_audio_file_dir replaces --mysql_find_cmd.
829 - documentation update
830 - man pages
831 - header file cleanup
832 - para_client code cleanup
833 - para_gui: faster display of output of display commands
834
835 ------------------------------------------
836 0.2.5 (2005-10-13) "aggressive resolution"
837 ------------------------------------------
838
839 This release adds internal senders, i.e. no more external programs are
840 spawned for sending out the audio data. There are two different senders
841 available: The http sender and the ortp sender (former para_send which
842 is no longer needed).
843
844 The new sender code has a plugin-like design so it can be easily
845 extended should there be be any future need for supporting another
846 network streaming protocol. All senders are completely independent of
847 each other. In particular, the http and the ortp sender can operate
848 in parallel.
849
850 - new server command: sender to control senders at runtime.
851 Read the output of "para_server -h" and "para_client help
852 sender" for more information.
853 - para_recv renamed to para_ortp_recv
854 - new executable: para_http_recv, a simple command line
855 http receiver.
856 - major afs/mp3/ogg code simplifications due to internal
857 senders.
858 - ogg timing improvements
859 - fix several minor memory leaks (found by valgrind)
860 - empty stream definitions work again
861 - com_ne(): ignore errors on remove
862 - audiod: fix segfault on server restart
863
864 ---------------------------------------
865 0.2.4 (2005-09-21) "toxic anticipation"
866 ---------------------------------------
867
868 Several small improvements, fixes and the new grab command.
869
870 - audiod:
871 - new command: "grab" to grab the output of the stream reader
872 or any filters. Read the output of "para_audioc help grab"
873 for more information.
874 - fix memory leak
875 - code cleanup
876 - audioc: new command line option: --bufsize to specify a
877 buffer size different from the default size 8192.
878 - improved error diagnostics for para_play.
879 - new configure option: --enable-ssldir so search for openssl in
880 non-standard places
881 - sdl_gui: Make it look nice again for 1024x768
882 - server: report total size of memory allocated with sbrk by malloc,
883 new command line option: --announce_time
884
885 -----------------------------------------
886 0.2.3 (2005-09-01) "hydrophilic movement"
887 -----------------------------------------
888
889 Two new executables and major feature enhancements.
890
891 - audiod filters: It is now possible to specify arbitrary many
892 (including none) filters for each supported audio
893 format. This can be used e.g. for normalizing volume,
894 transforming or grabbing the audio stream, or for using
895 visualizers. Read the output of "para_audiod -h" for the
896 syntax of the new --filter_cmd option.
897 - new executable: para_play, a tiny alsa player. It
898 can play wave files or raw pcm (16 bit little endian)
899 from stdin.
900 - new executable: para_compress, a dynamic range compressor
901 intended to keep audio output at a consistent volume. Derived
902 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
903 - audiod: New option: --stream_delay. This can be used in
904 a local network to syncronize the audio output of all
905 clients that play the same stream.
906
907 ------------------------------------------
908 0.2.2 (2005-08-19) "tangential excitation"
909 ------------------------------------------
910
911 Mostly internal changes in this release, but also some new commands
912 for the mysql database tool.
913
914 - cleanup exec.c, fix para_exec bug
915 - compile time loglevel (log messages below the given level
916 won't be compiled in, which reduces the size of the
917 resulting binaries)
918 - new log macros that shorten the size of the source code.
919 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
920 to send only zeros. With this workaround, para_audioc works
921 again.
922 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
923 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
924 (new entry), "snp" (set numplayed). Read the manual for more
925 information.
926
927 ---------------------------------------
928 0.2.1 (2005-08-15) "surreal experience"
929 ---------------------------------------
930
931 Here comes paraslash-0.2.1. It contains a couple of new features and,
932 surprise, only minor bug fixes.
933
934 - kill noisy mp3 debug message
935 - cleanup of the build system
936 - para_server and para_client directly use the crypto routines
937 of the openssl library rather than invoking the openssl command
938 line utitlity
939 - server/audiod: new option --user to switch to the given user
940 when invoked as root. Read the output of "para_server -h" for
941 more information.
942 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
943 status. Default: "para_audioc stat"
944 - sdl_gui: new option --pic_cmd to be used to download the picture.
945 Default: "para_client pic"
946 - audiod: 5 slots ought to be enough for everybody
947 - audiod: new status item: Uptime, kill hup command
948
949 ------------------------------------------
950 0.2.0 (2005-08-06) "distributed diffusion"
951 ------------------------------------------
952
953 After several month of increased development activity, paraslash-0.2.0
954 has arrived. It contains many new features and is much more
955 self-contained than the old 0.1.x series. Enjoy!
956
957
958 - para_server: fix hang on song change and crash on sighup.
959 Speed up mysql queries. The DIR_LIKE macro is gone.
960 - new executables: para_audiod, the local audio daemon that
961 starts playback (uses SCM_CREDENTIALS socket magic) and
962 para_audioc, the corresponding client.
963 - new executables: para_mp3dec/para_oggdec, two really teensy
964 decoders. para_mp3dec is based on libmad, para_oggdec requires
965 libvorbisfile.
966 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
967 they are now called para_send and para_recv respectively.
968 - documentation updates
969 - para_gui is themable. For now there is the default theme that
970 looks as before and the simple theme: blue and easy.
971 - gui: audio streaming is now handled by audiod. Time display shows
972 playback time rather than streaming time
973 - slider: update to libzmw-0.2.0
974 - para_krell: fix crash on server shutdown
975 - switch from gzip to bzip2
976
977 ----------------------------------------
978 0.1.7 (2005-04-18) "melting penetration"
979 ----------------------------------------
980
981 The main change in this release is clearly the oggvorbis rewrite,
982 but there are also lots of smaller changes. If you intend to use both
983 the mp3 and the ogg plugin, it is recommended to use software mixing,
984 e.g. the dmix plugin which is provided by ALSA.
985
986 - new executables: para_ovsend and para_ovrecv for sending/receiving
987 oggvorbis files via rtp. Requires the open rtp library. Get it at
988 http://www.linphone.org/ortp/
989 - rewrite of the ogg_vorbis core code
990 - configure detects libzmw and, if detected, includes
991 para_slider to the list of binaries to be built by make
992 - server stream writers read from their associated fifo rather
993 than from stdin
994 - slider: two new sliders, lastplayed and numplayed
995 - fix nasty double free bug which caused random segfaults in case of
996 mp3 files with invalid header information
997 - gui: new command line option: --stream_timeout=seconds to
998 deactivate a slot if it is idle for that many seconds (default=`5')
999 - diffstats
1000
1001 ---------------------------------------
1002 0.1.6 (2005-03-05) "asymptotic balance"
1003 ---------------------------------------
1004
1005 Only little user-visible changes in this release. Mainly bugfixes and
1006 core code cleanup. This is probably the most stable version ever if you
1007 stick to mp3...
1008
1009 - fix several memory leaks
1010 - rename default name of mysql database from "music" to "paraslash".
1011 Use para_server's --mysql_database option if you do not want to
1012 rename your old database.
1013 - rework ogg vorbis code
1014 - make update command work on mysql servers with LOCAL_INFILE
1015 disabled
1016 - gui: improved stream I/O (slots)
1017 - simplified audio format API
1018 - para_pob_ogg is gone
1019
1020 ------------------------------------
1021 0.1.5 (2004-12-31) "opaque eternity"
1022 ------------------------------------
1023
1024 Let's slide gently into the new year.
1025
1026 - new: para_slider (not built automatically, type "make
1027 para_slider" to build). A toy for those who always felt that
1028 creating stream definitions is difficult. See screenshots,
1029 README and FEATURES for more info.
1030 - improved signal handling. Fixes server segfault on SIGHUP
1031 for linux kernels newer than Aug 24 2004 and makes para_gui
1032 race-free.
1033 - reload database tool on SIGHUP
1034 - improved help message for sl
1035 - do not log "broken pipe" messages as errors. They are
1036 perfectly ok.
1037 - fix wrong error message on permission errors
1038
1039 -----------------------------------------
1040 0.1.4 (2004-12-19) "tunneling transition"
1041 -----------------------------------------
1042
1043 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1044 Hopefully, most of them got wiped out with this release. Some
1045 enhancements went also in.
1046
1047 - improved error diagnostics for all commands
1048 - stradd/picadd: overwrite previous contents if entry already

1053 no server is running
1054 - si: report also server pid
1055 - server: don't busy-loop if dbtool reports only invalid files.
1056 - gui: CTRL+C works again, fix stream_read command line option

1060
1061 ---------------------------------------
1062 0.1.3: (2004-12-10) "vanishing inertia"
1063 ---------------------------------------
1064
1065 Starting from this release, the database tools are integrated in the
1066 server binary. This decreases server startup time, reduces code size
1067 and speeds up database commands. However, the layout of the underlying
1068 mysql database changed only slightly and 0.1.3 should be backwards
1069 compatible in that respect.
1070
1071 Visible changes:
1072
1073 - If mysql is not detected at compile time, or fails to init
1074 at runtime, fall back to the dopey database tool which should
1075 always work.
1076 - para_dbtool and dbtool.conf are gone. All mysql specific
1077 options are read from server.conf and are prefixed by 'mysql_'.
1078 - new command: cdt (change database tool)
1079 - new command line option: dbtool (choose startup database tool)
1080 - The name of current stream is now stored in the database,
1081 so paraslash remembers its current stream when restarted.
1082 - new command: csp (change stream and play)
1083 - para_gui also reports current database tool and server uptime
1084
1085 -------------------------------------------
1086 0.1.2: (2004-11-28) "spherical fluctuation"
1087 -------------------------------------------
1088
1089 Point release before the big dbtool changes go in.
1090
1091 - dbtool: rename ca to cam (copy all meta data). It now also
1092 copies numplayed and lastplayed time as well as the picture
1093 id.

1095

1121 and stream large audio sets happily)
1122 - paraslash is no longer restricted to one particular audio
1123 streaming software
1124 - new dbtool commands (stradd, strq, strdel) for easy stream
1125 managment w/o configuration file. That obsoletes stream_defs
1126 file/config option for dbtool.
1127 - picadd accepts jpeg data from stdin
1128 - new server commands: ps (select previous stream), sc (song change)
1129 - new default pictures for sdl_gui

1150 commands: refresh (^L), jmp (F1-F10)
1151 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
