26 ---------------------------------------------
27
28 Not many new features, but lots of fixes and usability improvements.
29
30 - para_gui has been converted to use the paraslash scheduler.
31 - Various alsa-related fixes, mostly for the raspberry pi.
32 - Many scheduler improvements and cleanups.
33 - The test suite has been extended to include sanity checks
34 for the generated man pages.
35 - ao_writer fixes. This writer was in a quite bad shape. Many
36 serious bugs have been fixed.
37 - new audiod command: version.
38 - Minor improvements to the bitstream API.
39 - The cpsi command now prints a meaningful error message if
40 none of the given patterns matched any audio file.

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

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

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

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

1048
1049 -----------------------------------------
1050 0.1.4 (2004-12-19) "tunneling transition"
1051 -----------------------------------------
1052
1053 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1054 Hopefully, most of them got wiped out with this release. Some
1055 enhancements went also in.
1056
1057 - improved error diagnostics for all commands
1058 - stradd/picadd: overwrite previous contents if entry already
1059 exists, rather than returning errors
1060 - stradd: use current stream if invoked without args
1061 - faster (and hopefully more stable) ogg-vorbis handling
1062 - para_krell: reap children to avoid zombie-flooding in case
1063 no server is running
1064 - si: report also server pid
1065 - server: don't busy-loop if dbtool reports only invalid files.
1066 - gui: CTRL+C works again, fix stream_read command line option
1067 - fix pic_add, hist
1068 - fix mysql dbtool startup in case no database exists
1069 - many small fixes and cleanups
1070
1071 ---------------------------------------
1072 0.1.3: (2004-12-10) "vanishing inertia"
1073 ---------------------------------------
1074
1075 Starting from this release, the database tools are integrated in the
1076 server binary. This decreases server startup time, reduces code size
1077 and speeds up database commands. However, the layout of the underlying
1078 mysql database changed only slightly and 0.1.3 should be backwards
1079 compatible in that respect.
1080
1081 Visible changes:
1082
1083 - If mysql is not detected at compile time, or fails to init
1084 at runtime, fall back to the dopey database tool which should
1085 always work.
1086 - para_dbtool and dbtool.conf are gone. All mysql specific
1087 options are read from server.conf and are prefixed by 'mysql_'.
1088 - new command: cdt (change database tool)
1089 - new command line option: dbtool (choose startup database tool)
1090 - The name of current stream is now stored in the database,
1091 so paraslash remembers its current stream when restarted.
1092 - new command: csp (change stream and play)
1093 - para_gui also reports current database tool and server uptime
1094
1095 -------------------------------------------
1096 0.1.2: (2004-11-28) "spherical fluctuation"
1097 -------------------------------------------
1098
1099 Point release before the big dbtool changes go in.
1100
1101 - dbtool: rename ca to cam (copy all meta data). It now also
1102 copies numplayed and lastplayed time as well as the picture
1103 id.

1105
1106 -----------------------------------------

1129
1130 - rename projectname from icc to paraslash (play, archive, rate
1131 and stream large audio sets happily)
1132 - paraslash is no longer restricted to one particular audio
1133 streaming software
1134 - new dbtool commands (stradd, strq, strdel) for easy stream
1135 managment w/o configuration file. That obsoletes stream_defs
1136 file/config option for dbtool.
1137 - picadd accepts jpeg data from stdin
1138 - new server commands: ps (select previous stream), sc (song change)
1139 - new default pictures for sdl_gui

1141 functions to arbitrary keys, nice help screen, rip out

1145 manipulating attributes

1159 - gui can start decoder (see config options). Further new gui
1160 commands: refresh (^L), jmp (F1-F10)
1161 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1162 terminates gui. This fixes dead instances consuming memory

1166 - codename funnies
