23 0.5.3 (2014-08-01) "symbolic synchronization"
24 ---------------------------------------------
25
26 Not many new features, but lots of fixes and usability improvements.

29 - Various alsa-related fixes, mostly for the raspberry pi.
30 - Many scheduler improvements and cleanups.
31 - The test suite has been extended to include sanity checks
32 for the generated man pages.

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

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

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

123 --------------------------------------
124 0.4.13 (2013-07-29) "spectral gravity"
125 --------------------------------------
126
127 One more 0.4.x release before the API-breaking changes for 0.5.0 go
128 in. The main features of this release are the ogg/opus audio format,
129 and UTF-8 support, but it includes also tons of other improvements
130 and fixes all over the place.
131
132 - New audio format: ogg/opus.
133 - UTF8 support for para_gui and the mp3 audio format handler.
134 - Scheduler improvements and fixes.
135 - The obsolete gettimeofday() function has been replaced
136 by clock_gettime() on systems which support it.
137 - Speed and usability improvements for para_gui.
138 - para_client now restores the fd flags of stdin and stdout
139 on shutdown.
140 - Improved manual pages.
141 - Consistent version strings for all executables.
142 - Reduced dependencies on generated files result in fewer
143 recompilations on changes.
144 - Performance improvements for the compress filter.
145 - Improved downloads web page.
146
147 -----------------------------------------
148 0.4.12 (2012-12-20) "volatile relativity"
149 -----------------------------------------
150 The new command line player, the resample filter, ALSA support for
151 para_fade, and the improved build system are the highlights of this
152 release which probably marks the end of the 0.4.x series.
153
154 - The afh receiver and the para_play executable.
155 - The resample filter: A sample rate converter based on
156 libsamplerate.
157 - The "versions" directory has been removed from the master
158 branch. The tarballs of the old releases are now available
159 in the new "releases" branch.
160 - Overhaul of the build system: All generated files are now
161 written to the "build" directory.
162 - The modular mixer API and the alsa mixer.
163 - Minor fixes for the osx writer.
164
165 --------------------------------------
166 0.4.11 (2012-07-20) "mutual diversity"
167 --------------------------------------
168
169 The major feature in this release is the new sideband API for
170 client-server communication. This API will be used exclusively starting
171 with 0.5.0, which breaks backward compatibility but allows to get rid
172 of quite some compatibility code. Other noteworthy changes include
173 decoder latency improvements and a long-standing bug fix for the
174 ALSA writer.
175
176 - Sideband connections: If both para_server and para_client
177 support this feature, data is sent as a multiplexed stream.
178 - The --no_default_filters option of para_filter has been
179 removed.
180 - Several fixes and latency improvements to various decoders.
181 - The ALSA writer now limits the prebuffer time to 500ms.
182 - Documentation improvements.
183 - Overhaul of the command_util.sh script.
184 - Fixes for some minor problems found by the clang analyzer.
185 - Compiles (almost) without warnings on gcc-3.
186 - Robustness improvements of the buffer tree code.
187
188 ------------------------------------------
189 0.4.10 (2012-03-30) "heterogeneous vacuum"
190 ------------------------------------------
191
192 Nothing earth-shaking in this release, but quite a few usability
193 improvements and the usual mix of cleanups and fixes.
194
195 - The --no_default_filters option of para_filter has been
196 deprecated. It still works but has no effect and will be
197 removed in the next version.
198 - para_gui now prints also the stderr output of the executing
199 command in the bottom window.
200 - Cleanup and consolidation of the various wrappers for
201 write(), writev(), send() and friends.
202 - The obscure error messages on mmap() failures have been
203 replaced by meaningful messages. This affects mainly
204 para_afh.
205 - para_audioc: Cleanups and memory leak fixes.
206 - Test 0004-server no longer fails if para_server is not
207 being built.
208 - New configure options: --with-id3tag-{headers,libs}.
209
210 -------------------------------------
211 0.4.9 (2011-12-06) "hybrid causality"
212 -------------------------------------
213
214 Support for another audio format, interactive mode for para_client
215 and para_audiod and many small improvements/fixes all over the place.
216
217 - Support for flac, the free lossless audio codec.
218 - Fix for an endless loop in the mp3 decoder for certain
219 (corrupt) mp3 files.
220 - When executed without specifying a command, para_client
221 and para_audioc start an interactive shell (requires
222 libreadline being installed). The interactive mode offers
223 full tab completion and command line history.
224 - autogen.sh now detects a distcc setup and adjusts the
225 parameter for the -j option of make accordingly.
226 - Shared memory areas are no longer restricted to 64K. We now
227 detect the maximal size of a shared memory area at runtime.
228 - cleanup of the internal uptime API.
229 - para_server prefaults the mmapped audio file to avoid
230 delays on slow media.
231 - A new test for the test-suite that exercises the
232 communication between para_server and para_audiod.
233 - The alsa writer eats up less CPU cycles when configured to
234 use the DMIX plugin.
235 - Simplified and unified receiver code.
236 - Makefile cleanups.
237 - Commands which print a list of matching audio files now
238 emit a meaningful error message if no audio file matched the
239 given pattern(s).
240
241 --------------------------------------
242 0.4.8 (2011-08-19) "nested assignment"
243 --------------------------------------
244
245 Gcrypt support, the overhauled osx writer and regex format specifiers
246 are the highlights of this release.
247
248 - support for libgcrypt as a drop-in replacement for openssl.
249 Run configure --enable-cryptolib=gcrypt to link against
250 libgcrypt. The two crypto implementations are compatible to
251 each other, i.e. a para_client executable linked against
252 gcrypt can connect to para_server linked against libssl
253 and vice versa.
254 - Rewrite of the osx writer (output plugin for Mac OS).
255 - audiod: The format specifier for receivers, filters and
256 writers is now treated as a regular expression. This allows
257 to replace 5 lines in the config file (one for each audio
258 format) by one single line. See the manual for details.
259 - The *.cmdline.[ch] files are no longer contained in the released
260 tarballs. This reduces the size of the tarballs but requires
261 gengetopt to build the tarball.
262 - Compiles cleanly also with llvm/clang.
263 - Corrupt mp3 files are handled more gracefully.
264 - The alsa writer uses poll fds instead of computing timeouts.
265 - Cleanup of the generic writer API.
266 - sched: Optimized zero timeouts.
267 - vss timeout cleanups.
268 - oggdec fixes and improvements.
269
270 --------------------------------------
271 0.4.7 (2011-06-01) "infinite rollback"
272 --------------------------------------
273
274 The new ao writer, support for ssh RSA keys and a couple of other
275 enhancements.
276
277 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
278 platforms through the libao audio library.
279 - Support for RSA keys generated with ssh-keygen.
280 - configure: improved options for ogg/vorbis/speex.
281 - The git version reported by --version always matches HEAD.
282 - The autogen script detects the number of processors and
283 runs a parallel make if possible.
284 - Major cleanup of the crypto API.
285 - Documentation updates.
286
287 ------------------------------------------
288 0.4.6 (2011-03-31) "deterministic entropy"
289 ------------------------------------------
290
291 Lots of ogg/vorbis improvements, the new test suite, enhancements
292 for para_gui and a fair amount of other bug fixes.
293
294 - For DCCP/OGG streams the audio file header is only sent once
295 at the beginning of the stream rather than periodically
296 every five seconds. This reduces network traffic and the
297 FEC group size.
298 - The vorbis comment header is replaced by an empty dummy header
299 before the header is sent over the network. This also results in
300 less network traffic and smaller FEC groups.
301 - The new "test" make target allows to perform some sanity checks prior
302 to installing the package.
303 - ogg timing fixes and performance improvements
304 - Scheduler improvements
305 - Proper exit codes for para_write
306 - para_gui: New option --theme to select a startup theme. Several
307 other improvements and fixes.
308 - aacdec error message cleanups
309 - simplified color error handling
310
311 --------------------------------------------
312 0.4.5 (2010-12-17) "symmetric randomization"
313 --------------------------------------------
314
315 Bug fixes, internal cleanups and variable-sized FEC slices.
316
317 - Contains a fix for an invalid-free-bug in the ogg audio format
318 handler code.
319 - Switching off the DCCP sender works again.
320 - para_audiod handles crashes of para_server more robustly.
321 - Internal scheduler and writer cleanups.
322 - Reduced latency due to variable-sized FEC slices.
323 - Improved documentation and error diagnostics.
324 - The build of para_server is now optional, allowing the build
325 to succeed in case libosl is not installed.
326
327 ------------------------------------------
328 0.4.4 (2010-08-06) "persistent regularity"
329 ------------------------------------------
330
331 Support for yet another audio format, para_write improvements and
332 bug fixes.
333
334 - Support for the speex codec.
335 - Support for sample formats other than 16 bit little endian.
336 - error2.h is now created by a perl script which speeds up configure
337 considerably.
338 - Fix a bug in the aac decoder which could lead to segfaults in
339 para_filter/para_audiod.
340 - Fixes for autoconf-2.66.
341
342 ----------------------------------------
343 0.4.3 (2010-07-05) "imaginary radiation"
344 ----------------------------------------
345
346 Many improvements for the DCCP and the UDP transport, the new user
347 manual and the usual mix of bug fixes and internal improvements.
348
349 - FEC support for the DCCP sender (Gerrit Renker). The new
350 --dccp_max_slice_size, --dccp_data_slices_per_group and
351 --dccp_slices_per_group options can be used to set the FEC
352 parameters for the DCCP transport.
353 - DNS lookups for UDP targets (Gerrit Renker).
354 - The new user manual replaces the README, README.afs, REQUIREMENTS
355 and INSTALL documents.
356 - Fix an end-of-file detection bug in the oggdec filter.
357 - The new nonblock API.
358 - Both options of the oggdec filter have been removed.
359 - New debug mode for the internal scheduler.
360
361 ------------------------------------------
362 0.4.2 (2010-04-23) "associative expansion"
363 ------------------------------------------
364
365 It's been some time since the last release, but finally here is
366 paraslash-0.4.2. The bulk of the changes comes from the new buffer
367 tree API, but there are changes all over the tree. Mainly performance
368 and usability improvements, but also quite some bug fixes.
369
370 - The new buffer tree API.
371 - DCCP: Support for CCID negotiation (Gerrit Renker).
372 - UDP robustness fixes.
373 - The --bufsize option for mp3dec is gone as it no longer makes sense
374 for the new buffer tree API.
375 - Fix audible buffer underruns for wma streams.
376 - The alsa writer no longer prints meaningless underrun durations.
377 - audiod: Defaults work also for udp streams. If no filter is
378 given for an audio format that is received via upd, fecdec is
379 automatically added as the first filter (along with the decoder).
380
381 ---------------------------------------
382 0.4.1 (2009-12-22) "concurrent horizon"
383 ---------------------------------------
384
385 Support for another audio format, minor feature enhancements and lots of bug
386 fixes. All fixes that have been accumulated in the maint branch (in particular
387 those mentionened in the 0.3.6 release notes) appear in this release as well.
388
389 - wma support.
390 - new afh option: --human to activate human-readable output.
391 - new server/audiod option: --log-timing to print timing information.
392 - build system improvements.
393 - source code documentation updates.
394
395 -------------------------------------
396 0.3.6 (2009-12-07) "cubic continuity"
397 -------------------------------------
398
399 Quite a few bugs have been found and fixed since 0.3.5, so here's
400 another 0.3.x release. No new features.
401
402 - Always check return value of malloc().
403 - ogg vorbis/FEC: Do not write garbage after the audio file header.
404 - exit if root privileges could not be dropped.
405 - FEC: Fix computation of extra slices.
406 - oss: Fix check for empty input buffer.
407 - Avoid buffer underruns due to filter chain output buffer constraints.
408 - server: Fix assignment of afs_pid.
409 - Don't panic if the afs database contains unknown audio formats.
410 - http/dccp: Do not send the audio file header twice.
411 - FEC: Timing improvements.
412
413 ----------------------------------------------
414 0.4.0 (2009-11-10) "simultaneous independence"
415 ----------------------------------------------
416
417 Two significant changes which require the new version number: The
418 improved authentication dialog and the fact that the database code
419 has been moved to a library, libosl. To use the new version, you have
420 to generate new RSA keys, see INSTALL for details. A shell script is
421 provided for conversion of the 0.3 database to the new 0.4 format.
422
423 - stronger crypto for client authentication
424 - the database code has been moved to a library
425 - improved status item handling
426 - cleanup of the build system
427 - The "-V" option now also prints the git version
428 - the new parser-friendly listing mode for the ls and stat commands
429 - mandatory rc4 encryption
430 - major audio format handler cleanups
431 - (id3,...) tags are no longer stored as a combined string in the database
432 - new mood methods: artist_matches, title_matches, comment_matches,
433 album_matches, year_maches, year.
434
435 --------------------------------------------
436 0.3.5 (2009-09-21) "symplectic separability"
437 --------------------------------------------
438
439 Full client support for *BSD Unixes, complete re-write of the ogg
440 vorbis audio format handler, various improvements all over the place
441 and the usual mix of bugfixes. This release marks the end of the 0.3
442 series if no serious problems show up.
443
444 - the new oss writer (supported on *BSD and Linux)
445 - rewrite of the ogg vorbis audio format handler. It's
446 recommended to replace the chunk tables of existing ogg
447 vorbis files in the afs database by re-adding these files
448 with "add -f".
449 - support for netmask subsets (Gerrit Renker)
450 - the new prebuffer filter
451 - improved signal handling
452 - variable fec output buffer size
453 - improved FEC timing fixes audible buffer underruns in UDP mode
454 - --log_color actually works
455 - new ls option: -d (print dates as seconds after the epoch)
456 - update to gengetopt 2.22.2
457 - support for RSA keys of size > 512 bits
458 - new option "mixer_channel" for para_fade
459
460 -----------------------------------------
461 0.3.4 (2009-05-07) "elliptic inheritance"
462 -----------------------------------------
463
464 The new udp sender, forward error correction, colored logs and various
465 other improvements. As the udp sender does not depend on any special
466 libraries, it is built unconditionally.
467
468 - The udp sender replaces the ortp sender. The new code uses forward
469 error correction to protect against packet losses. Many thanks to
470 Gerrit Renker for providing ipv6 support.
471 - The default port for udp streaming now defaults to 8000, like
472 for the http and the dccp senders/receivers.
473 - Loglevels are now specified as symbolic names, e.g.
474 "--loglevel info".
475 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
476 - para_server/para_audiod: Color support for log messages.
477 - new options for mp3dec: --ignore-crc, --bufsize
478 - new audiod option: --config-file.
479 - gengetopt cleanups.
480 - Improved help/man pages: The documentation of para_audiod,
481 para_recv, para_filter and para_write now also contains
482 all options of the available receivers/filters/writers. The
483 man page of para_fade contains a description of the different
484 modes of operation.
485 - More source code documentation.
486 - vss timing fixes.
487
488 --------------------------------------------
489 0.3.3 (2008-12-01) "axiomatic perspectivity"
490 --------------------------------------------
491
492 Internal code cleanups, bug fixes, improved tag handling and the new
493 amplification filter.
494
495 - para_server uses the generic scheduling code.
496 - overhaul of the virtual streaming system.
497 - mp3: id3 version 2 support via libid3tag (optional)
498 - ogg: vorbis comment support.
499 - aac meta info support.
500 - mp3 audio format handler cleanups.
501 - new filter: "amp" to amplify the amplitude of the audio stream
502 - new status item/database entry: amplification. It is
503 used by the amp filter to pre-amplify the audio stream.
504 - fix a close-without-open bug in para_write.
505 - fix a bug in com_init() which was introduced in 0.3.2.
506 - better error diagnostics for para_client.
507
508 -----------------------------------------
509 0.3.2 (2008-04-11) "probabilistic parity"
510 -----------------------------------------
511
512 The new para_afh executable, scheduling and documentation improvements.
513
514 - new ls option: -lc (list chunk table)
515 - new executable: para_afh, the stand-alone audio file handler tool
516 - afs commands can send output more than SHMMAX (32MB on Linux). This
517 also reduces the memory usage of commands that produce large amounts
518 of output.
519 - major scheduler and audiod cleanups.
520 - more detailed and much nicer man pages.
521
522 ---------------------------------------
523 0.3.1 (2008-02-23) "liquid interaction"
524 ---------------------------------------
525
526 A mix of cleanups, bug fixes, improvements, and some new features. No
527 significant changes to the new database (osl) code, which is generally
528 a good sign.
529
530 - Share some similar/duplicate code between the http and the
531 dccp sender.
532 - Generic access control lists for paraslash senders.
533 - dccp sender: Access control lists, connection limiting and support
534 for the allow,deny,on,off,help sender commands.
535 - The default dccp port changed from 5001 to 8000 (suggested by
536 Gerrit Renker).
537 - para_server starts even if not all public keys could be loaded.
538 - Audiod performance improvements.
539 - fix a bug in the "off" command of the http sender.
540 - fix some fd and memory leaks.
541 - Update to gengetopt-2.22.
542
543 -------------------------------------
544 0.3.0 (2008-01-12) "solar saturation"
545 -------------------------------------
546
547 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
548
549
550 Usually one might expect lots of new features AND a big increase in size
551 for a major release like this.
552
553 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
554 ever. The decrease in size is mostly due to the removal of some
555 graphical tools (which were only quick hacks anyway). But also the
556 fact that the mysql code is gone cuts down the size a bit.
557
558 Being independent of mysql comes at a cost: The fact that paraslash
559 now contains its own database (the object storage layer, osl) increases
560 the (stripped) binary size of para_server by ~50K on i386.
561
562 - no more restrictions on unique basenames.
563 - independent of mysql: The new self-contained object
564 storage layer (osl) replaces the mysql database.
565 - New executable para_fsck: Check integrity of osl tables.
566 - Lyrics support.
567 - Reliable audio file move/rename detection.
568 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
569 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
570 Solaris (sparc64).
571 - the new osl-based audio file selector (afs) replaces the random,
572 the playlist and the mysql selector of paraslash-0.2.x.
573 - IPv6 support (thanks to Gerrit Renker).
574 - paraslash-0.2.x streams are now called "moods". Writing
575 0.3.x-mood definitions should be both easier and more
576 powerful than writing 0.2.x-stream definitions.
577 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
578 been removed. The world is a better place without them. However,
579 para_gui is still there.
580 - afs tracks audio file selection also in playlist mode.
581 - few easy-to-use afs commands replace the many not-so-easy-to-use
582 mysql commands (and are available also in playlist mode).
583 - Improved error subsystem.
584 - The earth-shaking new logo.
585
586 -----------------------------------------
587 0.2.17 (2007-11-20) "isotropic threshold"
588 -----------------------------------------
589
590 Mainly bugfixes and cleanups in this version which marks the end of
591 the 0.2.x series if no serious bugs show up after the release.
592
593 - mysql_selector: fix a locking bug.
594 - universal chunk queueing.
595 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
596 to Gerrit Renker).
597 - be more carful wrt. signed vs. unsigned argument passing.
598 - cleanup error.h and fix some references to invalid error
599 codes.
600 - update to gengetopt-2.21.
601 - update to ortp-0.13.1.
602 - autoconf: extend checks for headers, library functions and
603 compiler characteristics.
604 - Fix streaming of large mp3 files.
605 - Fix an off-by-one bug in playlist handling.
606
607 --------------------------------------
608 0.2.16 (2007-04-05) "neural discharge"
609 --------------------------------------
610
611 The main change in this release is the major audio format handler
612 cleanup which removes some similar/duplicate code and makes it easier
613 to implement plugins for other audio formats. Of course, the usual mix
614 of other improvements/changes/bugfixes also made it into the release.
615
616 - simplified audio format handlers (most of the handling functions
617 were moved one layer up to the virtual streaming system).
618 - para_server uses mmap to read audio files
619 - repositioning of mp3 streams is much faster, in particular for
620 jumping near the end of large mp3 files.
621 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
622 and AFS_WRITE.
623 - fix a bug in para_filter that caused decoding of aac files
624 to start only after a few seconds.
625 - fix osx_writer hangs
626 - simplified dccp code (thanks to Gerrit Renker)
627 - the compress filter works also on big endian systems (ppc)
628
629 -----------------------------------------
630 0.2.15 (2007-02-16) "inductive resonance"
631 -----------------------------------------
632
633 Minor improvements, more documentation and a bunch of bug fixes.
634
635 - para_server: The server.users file is only read once on server
636 startup rather than for each connection
637 - mp3dec: Fix decoding of corrupt mp3 files
638 - afs (audio file sender) is now called vss (virtual streaming
639 system). Consequently, the permission flags specified in
640 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
641 become VSS_READ and VSS_WRITE respectively.
642 - para_audiod/para_filter: Fix a bug that caused the last chunk
643 of audio data not being written under certain circumstances
644 - audiod: compute the difference of server time and local time
645 correctly
646 - para_server/para_audiod: Fix some memory leaks
647 - documentation improvements
648 - configure.ac: fix checks for para_krell
649 - new man pages
650
651 -------------------------------------------
652 0.2.14 (2006-10-15) "transient singularity"
653 -------------------------------------------
654
655 The only major enhancement of this version is the osx writer which completes
656 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
657 until now for reasons beyond the scope of this changelog entry.
658
659 - new output plugin for Mac Os: the osx writer
660 - rename configure command line options from --enable-xxx-headers to
661 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
662 - configure: new command line options: --with-mad-headers,
663 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
664 - some robustness fixes
665 - dymamic audio format recognition for audiod
666 - para_server: new command line option: --autoplay_delay
667 - para_audiod: new command line option: --clock_diff_count
668
669 ---------------------------------------
670 0.2.13 (2006-07-14) "sonic convolution"
671 ---------------------------------------
672
673 A bunch of new features and core changes.
674
675 - the new paraslash scheduler, short and sweet.
676 - Support for m4a/mp4 files via the new aac audio format
677 handler/filter (requires libfaad).
678 - each writer has its own command line parser, just like
679 para_recv and para_filter.
680 - para_client and para_audioc use the error subsystem
681 - writers are integrated in para_audiod (currently linux-only)
682 - para_client is integrated in para_audiod
683 - random/playlist selector: improved info strings
684 - new audiod commands: tasks, kill
685 - update to libortp-0.10.1
686 - para_fade: wake time defaults to 8 hours from now
687 - update to autoconf-2.60
688
689 ------------------------------------------
690 0.2.12 (2006-05-12) "oriented abstraction"
691 ------------------------------------------
692
693 Many user-visible changes in this release and lots of new
694 features:
695
696
697 - the new optional dccp sender/receiver. It uses the datagram
698 congestion control protocol. You'll need a fairly new kernel
699 for this.
700 - paraslash works on Mac OS X (thanks to Gerd Becker)
701 - para_play renamed to para_write
702 - modular output plugin design (writers) for para_write
703 - new file_writer output plugin for para_write
704 - compress filter speed improvements
705 - update to libortp-0.9.1
706 - update to gengetopt-2.17rc
707 - para_client no longer depends on libreadline (as the
708 code for the interactive mode was removed).
709 - gcc-2-95 is no longer a supported compiler. It may still
710 work, but it gets no more testing.
711 - the tarball no longer contains the screenshot images which
712 reduces its size quite a bit.
713 - configure: new command line options: --enable-mysql-headers
714 and --enable-mysql-libs
715
716 ------------------------------------
717 0.2.11 (2006-03-11) "atomic duality"
718 ------------------------------------
719
720 Here it is, the first paraslash release developed with git. There
721 are fairly many user-visible changes in this release. As two out of
722 the three "database tools" of paraslash don't use a database at all,
723 they are now called "audio file selectors" instead.
724
725
726 - the cdt command (change database tool) becomes chs (change
727 selector)
728 - no more colon separators: The syntax of some options of
729 para_audiod and para_filter have changed. Use --help for
730 more info (and some examples).
731 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
732 - switch from cvs to git (should've done that earlier)
733 - the new ipc subsystem
734 - new audio file selector: playlist
735 - para_server: the dopey selector is now called "random",
736 and is the default selector. Use the --selector option to
737 choose another selector at startup, or the chs command to
738 change the selector at runtime.
739 - X86_64 fixes (thanks to Steffen Klassert)
740 - para_play fixes
741
742 --------------------------------------
743 0.2.10 (2006-02-17) "cyclic attractor"
744 --------------------------------------
745
746 Huge documentation update, a scrollable window for para_gui, ortp
747 improvements, and of course many small fixes not mentioned here.
748 The diffstat below is rather misleading as most insertions are due
749 to the new source documentation.
750
751 - autoconf cleanup
752 - para_server also uses the new error subsystem
753 - lots of new documentation (UTSL)
754 - gui improvements:
755 - keysyms for cursor keys and for next/previous page keys
756 - scrollable output window
757 - new internal commands: scroll up/down, page up/down
758 - fix color of command output.
759 - ortp: the --chunk_time and --header flags are no longer needed
760 for para_recv/para_audiod as this information is now encoded in
761 each rtp packet sent by para_server.
762
763 -------------------------------------------
764 0.2.9 (2006-01-24) "progressive turbulence"
765 -------------------------------------------
766
767 Internal audiod receivers/filters, the new error subsystem and
768 a lot of small improvements.
769
770 - para_recv and para_filter are integrated into the para_audiod
771 binary, i.e. audiod no longer spawns a new process for
772 each receiver/filter. As para_recv and para_filter might be
773 useful as standalone programs, they still get built (linked
774 against the same object files that are also used for audiod).
775 - further ortp timing improvements should reduce the CPU usage
776 of the ortp receiver.
777 - improved audio grabbing. The 'grab' command of para_audiod
778 has its own set of command line options. Read the output of
779 "para_audioc help grab" for more info.
780 - oggdec: configurable input prebuffer size.
781 - the new error subsystem gives better error diagnostics
782 and reduces code size.
783
784 -----------------------------------------
785 0.2.8 (2006-01-02) "dynamic accumulation"
786 -----------------------------------------
787
788 The new modular filter design and the para_play-hangs bugfix.
789
790 - new executable: para_filter. It combines para_mp3dec,
791 para_oggdec and para_compress. It also adds a further filter
792 type, wav, that just inserts a wave header at the desired point
793 of the filter chain. All 'piping' is done in-memory (i.e. no
794 read/write operations are used).
795 - para_play: fix a stupid bug that caused it to hang under
796 certain circumstances.
797
798 -------------------------------------------
799 0.2.7 (2006-12-27) "transparent invariance"
800 -------------------------------------------
801
802 Not many user-visible changes but a fair amount of internal improvements.
803
804
805 - The http sender buffers data if it can not be sent
806 out immediately (because the socket is not writable). This
807 should prevent para_server from shutting down the connection
808 too early on a loaded network.
809 - para_play also prebuffers data if it is told to start at a
810 future time by the --start_time option.
811 - The return of para_recv: It combines para_ortp_recv and
812 para_http_recv. Use the --receiver option to switch between
813 the two. para_recv builds without libortp, but contains
814 only the http receiver in this case.
815 - update to ortp 0.8.1. As this ortp release contains incompatible
816 changes, para_recv-0.2.7 won't link against older ortp libs.
817 - improved ortp timings.
818 - use of gcc-extensions that #define away for non-gcc and
819 gcc < 3.0.
820
821 -------------------------------------------
822 0.2.6 (2005-10-29) "recursive compensation"
823 -------------------------------------------
824
825 Transparent session encryption (uses openssl's Alleged RC4 cipher),
826 the internal find command and several other improvements and cleanups.
827
828 - Encrypt the session if encryption is requested by the client
829 (default for para_client 0.2.6). This is backwards
830 compatible, so older clients can still connect to para_server
831 0.2.6. Use the new client option --plain to request an
832 uncrypted session (off by default, must be set to on in
833 order to connect to para_server 0.2.x with 0 <= x <= 5).
834 - para_server uses an internal function to locate audio files
835 rather than calling find(1). The server option
836 --mysql_audio_file_dir replaces --mysql_find_cmd.
837 - documentation update
838 - man pages
839 - header file cleanup
840 - para_client code cleanup
841 - para_gui: faster display of output of display commands
842
843 ------------------------------------------
844 0.2.5 (2005-10-13) "aggressive resolution"
845 ------------------------------------------
846
847 This release adds internal senders, i.e. no more external programs are
848 spawned for sending out the audio data. There are two different senders
849 available: The http sender and the ortp sender (former para_send which
850 is no longer needed).
851
852 The new sender code has a plugin-like design so it can be easily
853 extended should there be be any future need for supporting another
854 network streaming protocol. All senders are completely independent of
855 each other. In particular, the http and the ortp sender can operate
856 in parallel.
857
858 - new server command: sender to control senders at runtime.
859 Read the output of "para_server -h" and "para_client help
860 sender" for more information.
861 - para_recv renamed to para_ortp_recv
862 - new executable: para_http_recv, a simple command line
863 http receiver.
864 - major afs/mp3/ogg code simplifications due to internal
865 senders.
866 - ogg timing improvements
867 - fix several minor memory leaks (found by valgrind)
868 - empty stream definitions work again
869 - com_ne(): ignore errors on remove
870 - audiod: fix segfault on server restart
871
872 ---------------------------------------
873 0.2.4 (2005-09-21) "toxic anticipation"
874 ---------------------------------------
875
876 Several small improvements, fixes and the new grab command.
877
878 - audiod:
879 - new command: "grab" to grab the output of the stream reader
880 or any filters. Read the output of "para_audioc help grab"
881 for more information.
882 - fix memory leak
883 - code cleanup
884 - audioc: new command line option: --bufsize to specify a
885 buffer size different from the default size 8192.
886 - improved error diagnostics for para_play.
887 - new configure option: --enable-ssldir so search for openssl in
888 non-standard places
889 - sdl_gui: Make it look nice again for 1024x768
890 - server: report total size of memory allocated with sbrk by malloc,
891 new command line option: --announce_time
892
893 -----------------------------------------
894 0.2.3 (2005-09-01) "hydrophilic movement"
895 -----------------------------------------
896
897 Two new executables and major feature enhancements.
898
899 - audiod filters: It is now possible to specify arbitrary many
900 (including none) filters for each supported audio
901 format. This can be used e.g. for normalizing volume,
902 transforming or grabbing the audio stream, or for using
903 visualizers. Read the output of "para_audiod -h" for the
904 syntax of the new --filter_cmd option.
905 - new executable: para_play, a tiny alsa player. It
906 can play wave files or raw pcm (16 bit little endian)
907 from stdin.
908 - new executable: para_compress, a dynamic range compressor
909 intended to keep audio output at a consistent volume. Derived
910 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
911 - audiod: New option: --stream_delay. This can be used in
912 a local network to syncronize the audio output of all
913 clients that play the same stream.
914
915 ------------------------------------------
916 0.2.2 (2005-08-19) "tangential excitation"
917 ------------------------------------------
918
919 Mostly internal changes in this release, but also some new commands
920 for the mysql database tool.
921
922 - cleanup exec.c, fix para_exec bug
923 - compile time loglevel (log messages below the given level
924 won't be compiled in, which reduces the size of the
925 resulting binaries)
926 - new log macros that shorten the size of the source code.
927 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
928 to send only zeros. With this workaround, para_audioc works
929 again.
930 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
931 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
932 (new entry), "snp" (set numplayed). Read the manual for more
933 information.
934
935 ---------------------------------------
936 0.2.1 (2005-08-15) "surreal experience"
937 ---------------------------------------
938
939 Here comes paraslash-0.2.1. It contains a couple of new features and,
940 surprise, only minor bug fixes.
941
942 - kill noisy mp3 debug message
943 - cleanup of the build system
944 - para_server and para_client directly use the crypto routines
945 of the openssl library rather than invoking the openssl command
946 line utitlity
947 - server/audiod: new option --user to switch to the given user
948 when invoked as root. Read the output of "para_server -h" for
949 more information.
950 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
951 status. Default: "para_audioc stat"
952 - sdl_gui: new option --pic_cmd to be used to download the picture.
953 Default: "para_client pic"
954 - audiod: 5 slots ought to be enough for everybody
955 - audiod: new status item: Uptime, kill hup command
956
957 ------------------------------------------
958 0.2.0 (2005-08-06) "distributed diffusion"
959 ------------------------------------------
960
961 After several month of increased development activity, paraslash-0.2.0
962 has arrived. It contains many new features and is much more
963 self-contained than the old 0.1.x series. Enjoy!
964
965
966 - para_server: fix hang on song change and crash on sighup.
967 Speed up mysql queries. The DIR_LIKE macro is gone.
968 - new executables: para_audiod, the local audio daemon that
969 starts playback (uses SCM_CREDENTIALS socket magic) and
970 para_audioc, the corresponding client.
971 - new executables: para_mp3dec/para_oggdec, two really teensy
972 decoders. para_mp3dec is based on libmad, para_oggdec requires
973 libvorbisfile.
974 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
975 they are now called para_send and para_recv respectively.
976 - documentation updates
977 - para_gui is themable. For now there is the default theme that
978 looks as before and the simple theme: blue and easy.
979 - gui: audio streaming is now handled by audiod. Time display shows
980 playback time rather than streaming time
981 - slider: update to libzmw-0.2.0
982 - para_krell: fix crash on server shutdown
983 - switch from gzip to bzip2
984
985 ----------------------------------------
986 0.1.7 (2005-04-18) "melting penetration"
987 ----------------------------------------
988
989 The main change in this release is clearly the oggvorbis rewrite,
990 but there are also lots of smaller changes. If you intend to use both
991 the mp3 and the ogg plugin, it is recommended to use software mixing,
992 e.g. the dmix plugin which is provided by ALSA.
993
994 - new executables: para_ovsend and para_ovrecv for sending/receiving
995 oggvorbis files via rtp. Requires the open rtp library. Get it at
996 http://www.linphone.org/ortp/
997 - rewrite of the ogg_vorbis core code
998 - configure detects libzmw and, if detected, includes
999 para_slider to the list of binaries to be built by make
1000 - server stream writers read from their associated fifo rather
1001 than from stdin
1002 - slider: two new sliders, lastplayed and numplayed
1003 - fix nasty double free bug which caused random segfaults in case of
1004 mp3 files with invalid header information
1005 - gui: new command line option: --stream_timeout=seconds to
1006 deactivate a slot if it is idle for that many seconds (default=`5')
1007 - diffstats
1008
1009 ---------------------------------------
1010 0.1.6 (2005-03-05) "asymptotic balance"
1011 ---------------------------------------
1012
1013 Only little user-visible changes in this release. Mainly bugfixes and
1014 core code cleanup. This is probably the most stable version ever if you
1015 stick to mp3...
1016
1017 - fix several memory leaks
1018 - rename default name of mysql database from "music" to "paraslash".
1019 Use para_server's --mysql_database option if you do not want to
1020 rename your old database.
1021 - rework ogg vorbis code
1022 - make update command work on mysql servers with LOCAL_INFILE
1023 disabled
1024 - gui: improved stream I/O (slots)
1025 - simplified audio format API
1026 - para_pob_ogg is gone
1027
1028 ------------------------------------
1029 0.1.5 (2004-12-31) "opaque eternity"
1030 ------------------------------------
1031
1032 Let's slide gently into the new year.
1033
1034 - new: para_slider (not built automatically, type "make
1035 para_slider" to build). A toy for those who always felt that
1036 creating stream definitions is difficult. See screenshots,
1037 README and FEATURES for more info.
1038 - improved signal handling. Fixes server segfault on SIGHUP
1039 for linux kernels newer than Aug 24 2004 and makes para_gui
1040 race-free.
1041 - reload database tool on SIGHUP
1042 - improved help message for sl
1043 - do not log "broken pipe" messages as errors. They are
1044 perfectly ok.
1045 - fix wrong error message on permission errors
1046
1047 -----------------------------------------
1048 0.1.4 (2004-12-19) "tunneling transition"
1049 -----------------------------------------
1050
1051 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1052 Hopefully, most of them got wiped out with this release. Some
1053 enhancements went also in.
1054
1055 - improved error diagnostics for all commands
1056 - stradd/picadd: overwrite previous contents if entry already
1057 exists, rather than returning errors
1058 - stradd: use current stream if invoked without args
1059 - faster (and hopefully more stable) ogg-vorbis handling
1060 - para_krell: reap children to avoid zombie-flooding in case
1061 no server is running
1062 - si: report also server pid
1063 - server: don't busy-loop if dbtool reports only invalid files.
1064 - gui: CTRL+C works again, fix stream_read command line option
1065 - fix pic_add, hist
1066 - fix mysql dbtool startup in case no database exists
1067 - many small fixes and cleanups
1068
1069 ---------------------------------------
1070 0.1.3: (2004-12-10) "vanishing inertia"
1071 ---------------------------------------
1072
1073 Starting from this release, the database tools are integrated in the
1074 server binary. This decreases server startup time, reduces code size
1075 and speeds up database commands. However, the layout of the underlying
1076 mysql database changed only slightly and 0.1.3 should be backwards
1077 compatible in that respect.
1078
1079 Visible changes:
1080
1081 - If mysql is not detected at compile time, or fails to init
1082 at runtime, fall back to the dopey database tool which should
1083 always work.
1084 - para_dbtool and dbtool.conf are gone. All mysql specific
1085 options are read from server.conf and are prefixed by 'mysql_'.
1086 - new command: cdt (change database tool)
1087 - new command line option: dbtool (choose startup database tool)
1088 - The name of current stream is now stored in the database,
1089 so paraslash remembers its current stream when restarted.
1090 - new command: csp (change stream and play)
1091 - para_gui also reports current database tool and server uptime
1092
1093 -------------------------------------------
1094 0.1.2: (2004-11-28) "spherical fluctuation"
1095 -------------------------------------------
1096
1097 Point release before the big dbtool changes go in.
1098
1099 - dbtool: rename ca to cam (copy all meta data). It now also
1100 copies numplayed and lastplayed time as well as the picture
1101 id.
1102 - fix endless-loop-bug caused by mp3 files with invalid header
1103
1104 -----------------------------------------

1127
1128 - rename projectname from icc to paraslash (play, archive, rate
1129 and stream large audio sets happily)
1130 - paraslash is no longer restricted to one particular audio
1131 streaming software
1132 - new dbtool commands (stradd, strq, strdel) for easy stream
1133 managment w/o configuration file. That obsoletes stream_defs
1134 file/config option for dbtool.
1135 - picadd accepts jpeg data from stdin
1136 - new server commands: ps (select previous stream), sc (song change)
1137 - new default pictures for sdl_gui
1138 - gui: new key_map option for binding commands and internal
1139 functions to arbitrary keys, nice help screen, rip out
1140 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1141 show silly logo on startup
1142 - new executables: para_fade for fading volume, para_dbadm for
1143 manipulating attributes
1144 - cdb adds _all_ tables to mysql database

1157 - gui can start decoder (see config options). Further new gui
1158 commands: refresh (^L), jmp (F1-F10)
1159 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1160 terminates gui. This fixes dead instances consuming memory

1164 - codename funnies
