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

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

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

119 --------------------------------------
120 0.4.13 (2013-07-29) "spectral gravity"
121 --------------------------------------
122
123 One more 0.4.x release before the API-breaking changes for 0.5.0 go
124 in. The main features of this release are the ogg/opus audio format,
125 and UTF-8 support, but it includes also tons of other improvements
126 and fixes all over the place.
127
128 - New audio format: ogg/opus.
129 - UTF8 support for para_gui and the mp3 audio format handler.
130 - Scheduler improvements and fixes.
131 - The obsolete gettimeofday() function has been replaced
132 by clock_gettime() on systems which support it.
133 - Speed and usability improvements for para_gui.
134 - para_client now restores the fd flags of stdin and stdout
135 on shutdown.
136 - Improved manual pages.
137 - Consistent version strings for all executables.
138 - Reduced dependencies on generated files result in fewer
139 recompilations on changes.
140 - Performance improvements for the compress filter.
141 - Improved downloads web page.
142
143 -----------------------------------------
144 0.4.12 (2012-12-20) "volatile relativity"
145 -----------------------------------------
146 The new command line player, the resample filter, ALSA support for
147 para_fade, and the improved build system are the highlights of this
148 release which probably marks the end of the 0.4.x series.
149
150 - The afh receiver and the para_play executable.
151 - The resample filter: A sample rate converter based on
152 libsamplerate.
153 - The "versions" directory has been removed from the master
154 branch. The tarballs of the old releases are now available
155 in the new "releases" branch.
156 - Overhaul of the build system: All generated files are now
157 written to the "build" directory.
158 - The modular mixer API and the alsa mixer.
159 - Minor fixes for the osx writer.
160
161 --------------------------------------
162 0.4.11 (2012-07-20) "mutual diversity"
163 --------------------------------------
164
165 The major feature in this release is the new sideband API for
166 client-server communication. This API will be used exclusively starting
167 with 0.5.0, which breaks backward compatibility but allows to get rid
168 of quite some compatibility code. Other noteworthy changes include
169 decoder latency improvements and a long-standing bug fix for the
170 ALSA writer.
171
172 - Sideband connections: If both para_server and para_client
173 support this feature, data is sent as a multiplexed stream.
174 - The --no_default_filters option of para_filter has been
175 removed.
176 - Several fixes and latency improvements to various decoders.
177 - The ALSA writer now limits the prebuffer time to 500ms.
178 - Documentation improvements.
179 - Overhaul of the command_util.sh script.
180 - Fixes for some minor problems found by the clang analyzer.
181 - Compiles (almost) without warnings on gcc-3.
182 - Robustness improvements of the buffer tree code.
183
184 ------------------------------------------
185 0.4.10 (2012-03-30) "heterogeneous vacuum"
186 ------------------------------------------
187
188 Nothing earth-shaking in this release, but quite a few usability
189 improvements and the usual mix of cleanups and fixes.
190
191 - The --no_default_filters option of para_filter has been
192 deprecated. It still works but has no effect and will be
193 removed in the next version.
194 - para_gui now prints also the stderr output of the executing
195 command in the bottom window.
196 - Cleanup and consolidation of the various wrappers for
197 write(), writev(), send() and friends.
198 - The obscure error messages on mmap() failures have been
199 replaced by meaningful messages. This affects mainly
200 para_afh.
201 - para_audioc: Cleanups and memory leak fixes.
202 - Test 0004-server no longer fails if para_server is not
203 being built.
204 - New configure options: --with-id3tag-{headers,libs}.
205
206 -------------------------------------
207 0.4.9 (2011-12-06) "hybrid causality"
208 -------------------------------------
209
210 Support for another audio format, interactive mode for para_client
211 and para_audiod and many small improvements/fixes all over the place.
212
213 - Support for flac, the free lossless audio codec.
214 - Fix for an endless loop in the mp3 decoder for certain
215 (corrupt) mp3 files.
216 - When executed without specifying a command, para_client
217 and para_audioc start an interactive shell (requires
218 libreadline being installed). The interactive mode offers
219 full tab completion and command line history.
220 - autogen.sh now detects a distcc setup and adjusts the
221 parameter for the -j option of make accordingly.
222 - Shared memory areas are no longer restricted to 64K. We now
223 detect the maximal size of a shared memory area at runtime.
224 - cleanup of the internal uptime API.
225 - para_server prefaults the mmapped audio file to avoid
226 delays on slow media.
227 - A new test for the test-suite that exercises the
228 communication between para_server and para_audiod.
229 - The alsa writer eats up less CPU cycles when configured to
230 use the DMIX plugin.
231 - Simplified and unified receiver code.
232 - Makefile cleanups.
233 - Commands which print a list of matching audio files now
234 emit a meaningful error message if no audio file matched the
235 given pattern(s).
236
237 --------------------------------------
238 0.4.8 (2011-08-19) "nested assignment"
239 --------------------------------------
240
241 Gcrypt support, the overhauled osx writer and regex format specifiers
242 are the highlights of this release.
243
244 - support for libgcrypt as a drop-in replacement for openssl.
245 Run configure --enable-cryptolib=gcrypt to link against
246 libgcrypt. The two crypto implementations are compatible to
247 each other, i.e. a para_client executable linked against
248 gcrypt can connect to para_server linked against libssl
249 and vice versa.
250 - Rewrite of the osx writer (output plugin for Mac OS).
251 - audiod: The format specifier for receivers, filters and
252 writers is now treated as a regular expression. This allows
253 to replace 5 lines in the config file (one for each audio
254 format) by one single line. See the manual for details.
255 - The *.cmdline.[ch] files are no longer contained in the released
256 tarballs. This reduces the size of the tarballs but requires
257 gengetopt to build the tarball.
258 - Compiles cleanly also with llvm/clang.
259 - Corrupt mp3 files are handled more gracefully.
260 - The alsa writer uses poll fds instead of computing timeouts.
261 - Cleanup of the generic writer API.
262 - sched: Optimized zero timeouts.
263 - vss timeout cleanups.
264 - oggdec fixes and improvements.
265
266 --------------------------------------
267 0.4.7 (2011-06-01) "infinite rollback"
268 --------------------------------------
269
270 The new ao writer, support for ssh RSA keys and a couple of other
271 enhancements.
272
273 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
274 platforms through the libao audio library.
275 - Support for RSA keys generated with ssh-keygen.
276 - configure: improved options for ogg/vorbis/speex.
277 - The git version reported by --version always matches HEAD.
278 - The autogen script detects the number of processors and
279 runs a parallel make if possible.
280 - Major cleanup of the crypto API.
281 - Documentation updates.
282
283 ------------------------------------------
284 0.4.6 (2011-03-31) "deterministic entropy"
285 ------------------------------------------
286
287 Lots of ogg/vorbis improvements, the new test suite, enhancements
288 for para_gui and a fair amount of other bug fixes.
289
290 - For DCCP/OGG streams the audio file header is only sent once
291 at the beginning of the stream rather than periodically
292 every five seconds. This reduces network traffic and the
293 FEC group size.
294 - The vorbis comment header is replaced by an empty dummy header
295 before the header is sent over the network. This also results in
296 less network traffic and smaller FEC groups.
297 - The new "test" make target allows to perform some sanity checks prior
298 to installing the package.
299 - ogg timing fixes and performance improvements
300 - Scheduler improvements
301 - Proper exit codes for para_write
302 - para_gui: New option --theme to select a startup theme. Several
303 other improvements and fixes.
304 - aacdec error message cleanups
305 - simplified color error handling
306
307 --------------------------------------------
308 0.4.5 (2010-12-17) "symmetric randomization"
309 --------------------------------------------
310
311 Bug fixes, internal cleanups and variable-sized FEC slices.
312
313 - Contains a fix for an invalid-free-bug in the ogg audio format
314 handler code.
315 - Switching off the DCCP sender works again.
316 - para_audiod handles crashes of para_server more robustly.
317 - Internal scheduler and writer cleanups.
318 - Reduced latency due to variable-sized FEC slices.
319 - Improved documentation and error diagnostics.
320 - The build of para_server is now optional, allowing the build
321 to succeed in case libosl is not installed.
322
323 ------------------------------------------
324 0.4.4 (2010-08-06) "persistent regularity"
325 ------------------------------------------
326
327 Support for yet another audio format, para_write improvements and
328 bug fixes.
329
330 - Support for the speex codec.
331 - Support for sample formats other than 16 bit little endian.
332 - error2.h is now created by a perl script which speeds up configure
333 considerably.
334 - Fix a bug in the aac decoder which could lead to segfaults in
335 para_filter/para_audiod.
336 - Fixes for autoconf-2.66.
337
338 ----------------------------------------
339 0.4.3 (2010-07-05) "imaginary radiation"
340 ----------------------------------------
341
342 Many improvements for the DCCP and the UDP transport, the new user
343 manual and the usual mix of bug fixes and internal improvements.
344
345 - FEC support for the DCCP sender (Gerrit Renker). The new
346 --dccp_max_slice_size, --dccp_data_slices_per_group and
347 --dccp_slices_per_group options can be used to set the FEC
348 parameters for the DCCP transport.
349 - DNS lookups for UDP targets (Gerrit Renker).
350 - The new user manual replaces the README, README.afs, REQUIREMENTS
351 and INSTALL documents.
352 - Fix an end-of-file detection bug in the oggdec filter.
353 - The new nonblock API.
354 - Both options of the oggdec filter have been removed.
355 - New debug mode for the internal scheduler.
356
357 ------------------------------------------
358 0.4.2 (2010-04-23) "associative expansion"
359 ------------------------------------------
360
361 It's been some time since the last release, but finally here is
362 paraslash-0.4.2. The bulk of the changes comes from the new buffer
363 tree API, but there are changes all over the tree. Mainly performance
364 and usability improvements, but also quite some bug fixes.
365
366 - The new buffer tree API.
367 - DCCP: Support for CCID negotiation (Gerrit Renker).
368 - UDP robustness fixes.
369 - The --bufsize option for mp3dec is gone as it no longer makes sense
370 for the new buffer tree API.
371 - Fix audible buffer underruns for wma streams.
372 - The alsa writer no longer prints meaningless underrun durations.
373 - audiod: Defaults work also for udp streams. If no filter is
374 given for an audio format that is received via upd, fecdec is
375 automatically added as the first filter (along with the decoder).
376
377 ---------------------------------------
378 0.4.1 (2009-12-22) "concurrent horizon"
379 ---------------------------------------
380
381 Support for another audio format, minor feature enhancements and lots of bug
382 fixes. All fixes that have been accumulated in the maint branch (in particular
383 those mentionened in the 0.3.6 release notes) appear in this release as well.
384
385 - wma support.
386 - new afh option: --human to activate human-readable output.
387 - new server/audiod option: --log-timing to print timing information.
388 - build system improvements.
389 - source code documentation updates.
390
391 -------------------------------------
392 0.3.6 (2009-12-07) "cubic continuity"
393 -------------------------------------
394
395 Quite a few bugs have been found and fixed since 0.3.5, so here's
396 another 0.3.x release. No new features.
397
398 - Always check return value of malloc().
399 - ogg vorbis/FEC: Do not write garbage after the audio file header.
400 - exit if root privileges could not be dropped.
401 - FEC: Fix computation of extra slices.
402 - oss: Fix check for empty input buffer.
403 - Avoid buffer underruns due to filter chain output buffer constraints.
404 - server: Fix assignment of afs_pid.
405 - Don't panic if the afs database contains unknown audio formats.
406 - http/dccp: Do not send the audio file header twice.
407 - FEC: Timing improvements.
408
409 ----------------------------------------------
410 0.4.0 (2009-11-10) "simultaneous independence"
411 ----------------------------------------------
412
413 Two significant changes which require the new version number: The
414 improved authentication dialog and the fact that the database code
415 has been moved to a library, libosl. To use the new version, you have
416 to generate new RSA keys, see INSTALL for details. A shell script is
417 provided for conversion of the 0.3 database to the new 0.4 format.
418
419 - stronger crypto for client authentication
420 - the database code has been moved to a library
421 - improved status item handling
422 - cleanup of the build system
423 - The "-V" option now also prints the git version
424 - the new parser-friendly listing mode for the ls and stat commands
425 - mandatory rc4 encryption
426 - major audio format handler cleanups
427 - (id3,...) tags are no longer stored as a combined string in the database
428 - new mood methods: artist_matches, title_matches, comment_matches,
429 album_matches, year_maches, year.
430
431 --------------------------------------------
432 0.3.5 (2009-09-21) "symplectic separability"
433 --------------------------------------------
434
435 Full client support for *BSD Unixes, complete re-write of the ogg
436 vorbis audio format handler, various improvements all over the place
437 and the usual mix of bugfixes. This release marks the end of the 0.3
438 series if no serious problems show up.
439
440 - the new oss writer (supported on *BSD and Linux)
441 - rewrite of the ogg vorbis audio format handler. It's
442 recommended to replace the chunk tables of existing ogg
443 vorbis files in the afs database by re-adding these files
444 with "add -f".
445 - support for netmask subsets (Gerrit Renker)
446 - the new prebuffer filter
447 - improved signal handling
448 - variable fec output buffer size
449 - improved FEC timing fixes audible buffer underruns in UDP mode
450 - --log_color actually works
451 - new ls option: -d (print dates as seconds after the epoch)
452 - update to gengetopt 2.22.2
453 - support for RSA keys of size > 512 bits
454 - new option "mixer_channel" for para_fade
455
456 -----------------------------------------
457 0.3.4 (2009-05-07) "elliptic inheritance"
458 -----------------------------------------
459
460 The new udp sender, forward error correction, colored logs and various
461 other improvements. As the udp sender does not depend on any special
462 libraries, it is built unconditionally.
463
464 - The udp sender replaces the ortp sender. The new code uses forward
465 error correction to protect against packet losses. Many thanks to
466 Gerrit Renker for providing ipv6 support.
467 - The default port for udp streaming now defaults to 8000, like
468 for the http and the dccp senders/receivers.
469 - Loglevels are now specified as symbolic names, e.g.
470 "--loglevel info".
471 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
472 - para_server/para_audiod: Color support for log messages.
473 - new options for mp3dec: --ignore-crc, --bufsize
474 - new audiod option: --config-file.
475 - gengetopt cleanups.
476 - Improved help/man pages: The documentation of para_audiod,
477 para_recv, para_filter and para_write now also contains
478 all options of the available receivers/filters/writers. The
479 man page of para_fade contains a description of the different
480 modes of operation.
481 - More source code documentation.
482 - vss timing fixes.
483
484 --------------------------------------------
485 0.3.3 (2008-12-01) "axiomatic perspectivity"
486 --------------------------------------------
487
488 Internal code cleanups, bug fixes, improved tag handling and the new
489 amplification filter.
490
491 - para_server uses the generic scheduling code.
492 - overhaul of the virtual streaming system.
493 - mp3: id3 version 2 support via libid3tag (optional)
494 - ogg: vorbis comment support.
495 - aac meta info support.
496 - mp3 audio format handler cleanups.
497 - new filter: "amp" to amplify the amplitude of the audio stream
498 - new status item/database entry: amplification. It is
499 used by the amp filter to pre-amplify the audio stream.
500 - fix a close-without-open bug in para_write.
501 - fix a bug in com_init() which was introduced in 0.3.2.
502 - better error diagnostics for para_client.
503
504 -----------------------------------------
505 0.3.2 (2008-04-11) "probabilistic parity"
506 -----------------------------------------
507
508 The new para_afh executable, scheduling and documentation improvements.
509
510 - new ls option: -lc (list chunk table)
511 - new executable: para_afh, the stand-alone audio file handler tool
512 - afs commands can send output more than SHMMAX (32MB on Linux). This
513 also reduces the memory usage of commands that produce large amounts
514 of output.
515 - major scheduler and audiod cleanups.
516 - more detailed and much nicer man pages.
517
518 ---------------------------------------
519 0.3.1 (2008-02-23) "liquid interaction"
520 ---------------------------------------
521
522 A mix of cleanups, bug fixes, improvements, and some new features. No
523 significant changes to the new database (osl) code, which is generally
524 a good sign.
525
526 - Share some similar/duplicate code between the http and the
527 dccp sender.
528 - Generic access control lists for paraslash senders.
529 - dccp sender: Access control lists, connection limiting and support
530 for the allow,deny,on,off,help sender commands.
531 - The default dccp port changed from 5001 to 8000 (suggested by
532 Gerrit Renker).
533 - para_server starts even if not all public keys could be loaded.
534 - Audiod performance improvements.
535 - fix a bug in the "off" command of the http sender.
536 - fix some fd and memory leaks.
537 - Update to gengetopt-2.22.
538
539 -------------------------------------
540 0.3.0 (2008-01-12) "solar saturation"
541 -------------------------------------
542
543 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
544
545
546 Usually one might expect lots of new features AND a big increase in size
547 for a major release like this.
548
549 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
550 ever. The decrease in size is mostly due to the removal of some
551 graphical tools (which were only quick hacks anyway). But also the
552 fact that the mysql code is gone cuts down the size a bit.
553
554 Being independent of mysql comes at a cost: The fact that paraslash
555 now contains its own database (the object storage layer, osl) increases
556 the (stripped) binary size of para_server by ~50K on i386.
557
558 - no more restrictions on unique basenames.
559 - independent of mysql: The new self-contained object
560 storage layer (osl) replaces the mysql database.
561 - New executable para_fsck: Check integrity of osl tables.
562 - Lyrics support.
563 - Reliable audio file move/rename detection.
564 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
565 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
566 Solaris (sparc64).
567 - the new osl-based audio file selector (afs) replaces the random,
568 the playlist and the mysql selector of paraslash-0.2.x.
569 - IPv6 support (thanks to Gerrit Renker).
570 - paraslash-0.2.x streams are now called "moods". Writing
571 0.3.x-mood definitions should be both easier and more
572 powerful than writing 0.2.x-stream definitions.
573 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
574 been removed. The world is a better place without them. However,
575 para_gui is still there.
576 - afs tracks audio file selection also in playlist mode.
577 - few easy-to-use afs commands replace the many not-so-easy-to-use
578 mysql commands (and are available also in playlist mode).
579 - Improved error subsystem.
580 - The earth-shaking new logo.
581
582 -----------------------------------------
583 0.2.17 (2007-11-20) "isotropic threshold"
584 -----------------------------------------
585
586 Mainly bugfixes and cleanups in this version which marks the end of
587 the 0.2.x series if no serious bugs show up after the release.
588
589 - mysql_selector: fix a locking bug.
590 - universal chunk queueing.
591 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
592 to Gerrit Renker).
593 - be more carful wrt. signed vs. unsigned argument passing.
594 - cleanup error.h and fix some references to invalid error
595 codes.
596 - update to gengetopt-2.21.
597 - update to ortp-0.13.1.
598 - autoconf: extend checks for headers, library functions and
599 compiler characteristics.
600 - Fix streaming of large mp3 files.
601 - Fix an off-by-one bug in playlist handling.
602
603 --------------------------------------
604 0.2.16 (2007-04-05) "neural discharge"
605 --------------------------------------
606
607 The main change in this release is the major audio format handler
608 cleanup which removes some similar/duplicate code and makes it easier
609 to implement plugins for other audio formats. Of course, the usual mix
610 of other improvements/changes/bugfixes also made it into the release.
611
612 - simplified audio format handlers (most of the handling functions
613 were moved one layer up to the virtual streaming system).
614 - para_server uses mmap to read audio files
615 - repositioning of mp3 streams is much faster, in particular for
616 jumping near the end of large mp3 files.
617 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
618 and AFS_WRITE.
619 - fix a bug in para_filter that caused decoding of aac files
620 to start only after a few seconds.
621 - fix osx_writer hangs
622 - simplified dccp code (thanks to Gerrit Renker)
623 - the compress filter works also on big endian systems (ppc)
624
625 -----------------------------------------
626 0.2.15 (2007-02-16) "inductive resonance"
627 -----------------------------------------
628
629 Minor improvements, more documentation and a bunch of bug fixes.
630
631 - para_server: The server.users file is only read once on server
632 startup rather than for each connection
633 - mp3dec: Fix decoding of corrupt mp3 files
634 - afs (audio file sender) is now called vss (virtual streaming
635 system). Consequently, the permission flags specified in
636 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
637 become VSS_READ and VSS_WRITE respectively.
638 - para_audiod/para_filter: Fix a bug that caused the last chunk
639 of audio data not being written under certain circumstances
640 - audiod: compute the difference of server time and local time
641 correctly
642 - para_server/para_audiod: Fix some memory leaks
643 - documentation improvements
644 - configure.ac: fix checks for para_krell
645 - new man pages
646
647 -------------------------------------------
648 0.2.14 (2006-10-15) "transient singularity"
649 -------------------------------------------
650
651 The only major enhancement of this version is the osx writer which completes
652 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
653 until now for reasons beyond the scope of this changelog entry.
654
655 - new output plugin for Mac Os: the osx writer
656 - rename configure command line options from --enable-xxx-headers to
657 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
658 - configure: new command line options: --with-mad-headers,
659 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
660 - some robustness fixes
661 - dymamic audio format recognition for audiod
662 - para_server: new command line option: --autoplay_delay
663 - para_audiod: new command line option: --clock_diff_count
664
665 ---------------------------------------
666 0.2.13 (2006-07-14) "sonic convolution"
667 ---------------------------------------
668
669 A bunch of new features and core changes.
670
671 - the new paraslash scheduler, short and sweet.
672 - Support for m4a/mp4 files via the new aac audio format
673 handler/filter (requires libfaad).
674 - each writer has its own command line parser, just like
675 para_recv and para_filter.
676 - para_client and para_audioc use the error subsystem
677 - writers are integrated in para_audiod (currently linux-only)
678 - para_client is integrated in para_audiod
679 - random/playlist selector: improved info strings
680 - new audiod commands: tasks, kill
681 - update to libortp-0.10.1
682 - para_fade: wake time defaults to 8 hours from now
683 - update to autoconf-2.60
684
685 ------------------------------------------
686 0.2.12 (2006-05-12) "oriented abstraction"
687 ------------------------------------------
688
689 Many user-visible changes in this release and lots of new
690 features:
691
692
693 - the new optional dccp sender/receiver. It uses the datagram
694 congestion control protocol. You'll need a fairly new kernel
695 for this.
696 - paraslash works on Mac OS X (thanks to Gerd Becker)
697 - para_play renamed to para_write
698 - modular output plugin design (writers) for para_write
699 - new file_writer output plugin for para_write
700 - compress filter speed improvements
701 - update to libortp-0.9.1
702 - update to gengetopt-2.17rc
703 - para_client no longer depends on libreadline (as the
704 code for the interactive mode was removed).
705 - gcc-2-95 is no longer a supported compiler. It may still
706 work, but it gets no more testing.
707 - the tarball no longer contains the screenshot images which
708 reduces its size quite a bit.
709 - configure: new command line options: --enable-mysql-headers
710 and --enable-mysql-libs
711
712 ------------------------------------
713 0.2.11 (2006-03-11) "atomic duality"
714 ------------------------------------
715
716 Here it is, the first paraslash release developed with git. There
717 are fairly many user-visible changes in this release. As two out of
718 the three "database tools" of paraslash don't use a database at all,
719 they are now called "audio file selectors" instead.
720
721
722 - the cdt command (change database tool) becomes chs (change
723 selector)
724 - no more colon separators: The syntax of some options of
725 para_audiod and para_filter have changed. Use --help for
726 more info (and some examples).
727 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
728 - switch from cvs to git (should've done that earlier)
729 - the new ipc subsystem
730 - new audio file selector: playlist
731 - para_server: the dopey selector is now called "random",
732 and is the default selector. Use the --selector option to
733 choose another selector at startup, or the chs command to
734 change the selector at runtime.
735 - X86_64 fixes (thanks to Steffen Klassert)
736 - para_play fixes
737
738 --------------------------------------
739 0.2.10 (2006-02-17) "cyclic attractor"
740 --------------------------------------
741
742 Huge documentation update, a scrollable window for para_gui, ortp
743 improvements, and of course many small fixes not mentioned here.
744 The diffstat below is rather misleading as most insertions are due
745 to the new source documentation.
746
747 - autoconf cleanup
748 - para_server also uses the new error subsystem
749 - lots of new documentation (UTSL)
750 - gui improvements:
751 - keysyms for cursor keys and for next/previous page keys
752 - scrollable output window
753 - new internal commands: scroll up/down, page up/down
754 - fix color of command output.
755 - ortp: the --chunk_time and --header flags are no longer needed
756 for para_recv/para_audiod as this information is now encoded in
757 each rtp packet sent by para_server.
758
759 -------------------------------------------
760 0.2.9 (2006-01-24) "progressive turbulence"
761 -------------------------------------------
762
763 Internal audiod receivers/filters, the new error subsystem and
764 a lot of small improvements.
765
766 - para_recv and para_filter are integrated into the para_audiod
767 binary, i.e. audiod no longer spawns a new process for
768 each receiver/filter. As para_recv and para_filter might be
769 useful as standalone programs, they still get built (linked
770 against the same object files that are also used for audiod).
771 - further ortp timing improvements should reduce the CPU usage
772 of the ortp receiver.
773 - improved audio grabbing. The 'grab' command of para_audiod
774 has its own set of command line options. Read the output of
775 "para_audioc help grab" for more info.
776 - oggdec: configurable input prebuffer size.
777 - the new error subsystem gives better error diagnostics
778 and reduces code size.
779
780 -----------------------------------------
781 0.2.8 (2006-01-02) "dynamic accumulation"
782 -----------------------------------------
783
784 The new modular filter design and the para_play-hangs bugfix.
785
786 - new executable: para_filter. It combines para_mp3dec,
787 para_oggdec and para_compress. It also adds a further filter
788 type, wav, that just inserts a wave header at the desired point
789 of the filter chain. All 'piping' is done in-memory (i.e. no
790 read/write operations are used).
791 - para_play: fix a stupid bug that caused it to hang under
792 certain circumstances.
793
794 -------------------------------------------
795 0.2.7 (2006-12-27) "transparent invariance"
796 -------------------------------------------
797
798 Not many user-visible changes but a fair amount of internal improvements.
799
800
801 - The http sender buffers data if it can not be sent
802 out immediately (because the socket is not writable). This
803 should prevent para_server from shutting down the connection
804 too early on a loaded network.
805 - para_play also prebuffers data if it is told to start at a
806 future time by the --start_time option.
807 - The return of para_recv: It combines para_ortp_recv and
808 para_http_recv. Use the --receiver option to switch between
809 the two. para_recv builds without libortp, but contains
810 only the http receiver in this case.
811 - update to ortp 0.8.1. As this ortp release contains incompatible
812 changes, para_recv-0.2.7 won't link against older ortp libs.
813 - improved ortp timings.
814 - use of gcc-extensions that #define away for non-gcc and
815 gcc < 3.0.
816
817 -------------------------------------------
818 0.2.6 (2005-10-29) "recursive compensation"
819 -------------------------------------------
820
821 Transparent session encryption (uses openssl's Alleged RC4 cipher),
822 the internal find command and several other improvements and cleanups.
823
824 - Encrypt the session if encryption is requested by the client
825 (default for para_client 0.2.6). This is backwards
826 compatible, so older clients can still connect to para_server
827 0.2.6. Use the new client option --plain to request an
828 uncrypted session (off by default, must be set to on in
829 order to connect to para_server 0.2.x with 0 <= x <= 5).
830 - para_server uses an internal function to locate audio files
831 rather than calling find(1). The server option
832 --mysql_audio_file_dir replaces --mysql_find_cmd.
833 - documentation update
834 - man pages
835 - header file cleanup
836 - para_client code cleanup
837 - para_gui: faster display of output of display commands
838
839 ------------------------------------------
840 0.2.5 (2005-10-13) "aggressive resolution"
841 ------------------------------------------
842
843 This release adds internal senders, i.e. no more external programs are
844 spawned for sending out the audio data. There are two different senders
845 available: The http sender and the ortp sender (former para_send which
846 is no longer needed).
847
848 The new sender code has a plugin-like design so it can be easily
849 extended should there be be any future need for supporting another
850 network streaming protocol. All senders are completely independent of
851 each other. In particular, the http and the ortp sender can operate
852 in parallel.
853
854 - new server command: sender to control senders at runtime.
855 Read the output of "para_server -h" and "para_client help
856 sender" for more information.
857 - para_recv renamed to para_ortp_recv
858 - new executable: para_http_recv, a simple command line
859 http receiver.
860 - major afs/mp3/ogg code simplifications due to internal
861 senders.
862 - ogg timing improvements
863 - fix several minor memory leaks (found by valgrind)
864 - empty stream definitions work again
865 - com_ne(): ignore errors on remove
866 - audiod: fix segfault on server restart
867
868 ---------------------------------------
869 0.2.4 (2005-09-21) "toxic anticipation"
870 ---------------------------------------
871
872 Several small improvements, fixes and the new grab command.
873
874 - audiod:
875 - new command: "grab" to grab the output of the stream reader
876 or any filters. Read the output of "para_audioc help grab"
877 for more information.
878 - fix memory leak
879 - code cleanup
880 - audioc: new command line option: --bufsize to specify a
881 buffer size different from the default size 8192.
882 - improved error diagnostics for para_play.
883 - new configure option: --enable-ssldir so search for openssl in
884 non-standard places
885 - sdl_gui: Make it look nice again for 1024x768
886 - server: report total size of memory allocated with sbrk by malloc,
887 new command line option: --announce_time
888
889 -----------------------------------------
890 0.2.3 (2005-09-01) "hydrophilic movement"
891 -----------------------------------------
892
893 Two new executables and major feature enhancements.
894
895 - audiod filters: It is now possible to specify arbitrary many
896 (including none) filters for each supported audio
897 format. This can be used e.g. for normalizing volume,
898 transforming or grabbing the audio stream, or for using
899 visualizers. Read the output of "para_audiod -h" for the
900 syntax of the new --filter_cmd option.
901 - new executable: para_play, a tiny alsa player. It
902 can play wave files or raw pcm (16 bit little endian)
903 from stdin.
904 - new executable: para_compress, a dynamic range compressor
905 intended to keep audio output at a consistent volume. Derived
906 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
907 - audiod: New option: --stream_delay. This can be used in
908 a local network to syncronize the audio output of all
909 clients that play the same stream.
910
911 ------------------------------------------
912 0.2.2 (2005-08-19) "tangential excitation"
913 ------------------------------------------
914
915 Mostly internal changes in this release, but also some new commands
916 for the mysql database tool.
917
918 - cleanup exec.c, fix para_exec bug
919 - compile time loglevel (log messages below the given level
920 won't be compiled in, which reduces the size of the
921 resulting binaries)
922 - new log macros that shorten the size of the source code.
923 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
924 to send only zeros. With this workaround, para_audioc works
925 again.
926 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
927 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
928 (new entry), "snp" (set numplayed). Read the manual for more
929 information.
930
931 ---------------------------------------
932 0.2.1 (2005-08-15) "surreal experience"
933 ---------------------------------------
934
935 Here comes paraslash-0.2.1. It contains a couple of new features and,
936 surprise, only minor bug fixes.
937
938 - kill noisy mp3 debug message
939 - cleanup of the build system
940 - para_server and para_client directly use the crypto routines
941 of the openssl library rather than invoking the openssl command
942 line utitlity
943 - server/audiod: new option --user to switch to the given user
944 when invoked as root. Read the output of "para_server -h" for
945 more information.
946 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
947 status. Default: "para_audioc stat"
948 - sdl_gui: new option --pic_cmd to be used to download the picture.
949 Default: "para_client pic"
950 - audiod: 5 slots ought to be enough for everybody
951 - audiod: new status item: Uptime, kill hup command
952
953 ------------------------------------------
954 0.2.0 (2005-08-06) "distributed diffusion"
955 ------------------------------------------
956
957 After several month of increased development activity, paraslash-0.2.0
958 has arrived. It contains many new features and is much more
959 self-contained than the old 0.1.x series. Enjoy!
960
961
962 - para_server: fix hang on song change and crash on sighup.
963 Speed up mysql queries. The DIR_LIKE macro is gone.
964 - new executables: para_audiod, the local audio daemon that
965 starts playback (uses SCM_CREDENTIALS socket magic) and
966 para_audioc, the corresponding client.
967 - new executables: para_mp3dec/para_oggdec, two really teensy
968 decoders. para_mp3dec is based on libmad, para_oggdec requires
969 libvorbisfile.
970 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
971 they are now called para_send and para_recv respectively.
972 - documentation updates
973 - para_gui is themable. For now there is the default theme that
974 looks as before and the simple theme: blue and easy.
975 - gui: audio streaming is now handled by audiod. Time display shows
976 playback time rather than streaming time
977 - slider: update to libzmw-0.2.0
978 - para_krell: fix crash on server shutdown
979 - switch from gzip to bzip2
980
981 ----------------------------------------
982 0.1.7 (2005-04-18) "melting penetration"
983 ----------------------------------------
984
985 The main change in this release is clearly the oggvorbis rewrite,
986 but there are also lots of smaller changes. If you intend to use both
987 the mp3 and the ogg plugin, it is recommended to use software mixing,
988 e.g. the dmix plugin which is provided by ALSA.
989
990 - new executables: para_ovsend and para_ovrecv for sending/receiving
991 oggvorbis files via rtp. Requires the open rtp library. Get it at
992 http://www.linphone.org/ortp/
993 - rewrite of the ogg_vorbis core code
994 - configure detects libzmw and, if detected, includes
995 para_slider to the list of binaries to be built by make
996 - server stream writers read from their associated fifo rather
997 than from stdin
998 - slider: two new sliders, lastplayed and numplayed
999 - fix nasty double free bug which caused random segfaults in case of
1000 mp3 files with invalid header information
1001 - gui: new command line option: --stream_timeout=seconds to
1002 deactivate a slot if it is idle for that many seconds (default=`5')
1003 - diffstats
1004
1005 ---------------------------------------
1006 0.1.6 (2005-03-05) "asymptotic balance"
1007 ---------------------------------------
1008
1009 Only little user-visible changes in this release. Mainly bugfixes and
1010 core code cleanup. This is probably the most stable version ever if you
1011 stick to mp3...
1012
1013 - fix several memory leaks
1014 - rename default name of mysql database from "music" to "paraslash".
1015 Use para_server's --mysql_database option if you do not want to
1016 rename your old database.
1017 - rework ogg vorbis code
1018 - make update command work on mysql servers with LOCAL_INFILE
1019 disabled
1020 - gui: improved stream I/O (slots)
1021 - simplified audio format API
1022 - para_pob_ogg is gone
1023
1024 ------------------------------------
1025 0.1.5 (2004-12-31) "opaque eternity"
1026 ------------------------------------
1027
1028 Let's slide gently into the new year.
1029
1030 - new: para_slider (not built automatically, type "make
1031 para_slider" to build). A toy for those who always felt that
1032 creating stream definitions is difficult. See screenshots,
1033 README and FEATURES for more info.
1034 - improved signal handling. Fixes server segfault on SIGHUP
1035 for linux kernels newer than Aug 24 2004 and makes para_gui
1036 race-free.
1037 - reload database tool on SIGHUP
1038 - improved help message for sl
1039 - do not log "broken pipe" messages as errors. They are
1040 perfectly ok.
1041 - fix wrong error message on permission errors
1042
1043 -----------------------------------------
1044 0.1.4 (2004-12-19) "tunneling transition"
1045 -----------------------------------------
1046
1047 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1048 Hopefully, most of them got wiped out with this release. Some
1049 enhancements went also in.
1050
1051 - improved error diagnostics for all commands
1052 - stradd/picadd: overwrite previous contents if entry already
1053 exists, rather than returning errors
1054 - stradd: use current stream if invoked without args
1055 - faster (and hopefully more stable) ogg-vorbis handling
1056 - para_krell: reap children to avoid zombie-flooding in case
1057 no server is running
1058 - si: report also server pid
1059 - server: don't busy-loop if dbtool reports only invalid files.
1060 - gui: CTRL+C works again, fix stream_read command line option
1061 - fix pic_add, hist
1062 - fix mysql dbtool startup in case no database exists
1063 - many small fixes and cleanups
1064
1065 ---------------------------------------
1066 0.1.3: (2004-12-10) "vanishing inertia"
1067 ---------------------------------------
1068
1069 Starting from this release, the database tools are integrated in the
1070 server binary. This decreases server startup time, reduces code size
1071 and speeds up database commands. However, the layout of the underlying
1072 mysql database changed only slightly and 0.1.3 should be backwards
1073 compatible in that respect.
1074
1075 Visible changes:
1076
1077 - If mysql is not detected at compile time, or fails to init
1078 at runtime, fall back to the dopey database tool which should
1079 always work.
1080 - para_dbtool and dbtool.conf are gone. All mysql specific
1081 options are read from server.conf and are prefixed by 'mysql_'.
1082 - new command: cdt (change database tool)
1083 - new command line option: dbtool (choose startup database tool)
1084 - The name of current stream is now stored in the database,
1085 so paraslash remembers its current stream when restarted.
1086 - new command: csp (change stream and play)
1087 - para_gui also reports current database tool and server uptime
1088
1089 -------------------------------------------
1090 0.1.2: (2004-11-28) "spherical fluctuation"
1091 -------------------------------------------
1092
1093 Point release before the big dbtool changes go in.
1094
1095 - dbtool: rename ca to cam (copy all meta data). It now also
1096 copies numplayed and lastplayed time as well as the picture
1097 id.
1098 - fix endless-loop-bug caused by mp3 files with invalid header
1099
1100 -----------------------------------------

1123
1124 - rename projectname from icc to paraslash (play, archive, rate
1125 and stream large audio sets happily)
1126 - paraslash is no longer restricted to one particular audio
1127 streaming software
1128 - new dbtool commands (stradd, strq, strdel) for easy stream
1129 managment w/o configuration file. That obsoletes stream_defs
1130 file/config option for dbtool.
1131 - picadd accepts jpeg data from stdin
1132 - new server commands: ps (select previous stream), sc (song change)
1133 - new default pictures for sdl_gui
1134 - gui: new key_map option for binding commands and internal
1135 functions to arbitrary keys, nice help screen, rip out
1136 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1137 show silly logo on startup
1138 - new executables: para_fade for fading volume, para_dbadm for
1139 manipulating attributes
1140 - cdb adds _all_ tables to mysql database

1148

1153 - gui can start decoder (see config options). Further new gui
1154 commands: refresh (^L), jmp (F1-F10)
1155 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1156 terminates gui. This fixes dead instances consuming memory

1160 - codename funnies
