7 - On Linux systems, local sockets are now created in the
8 abstract name space by default. This allows to get rid of
9 the socket specials in /var/paraslash.
10 - New autoconf macros to avoid duplication in configure.ac.
11 - Status items (as shown by para_gui) are updated correctly
12 when the meta information of the current audio changes.

38 ---------------------------------------------
39
40 Not many new features, but lots of fixes and usability improvements.
41
42 - para_gui has been converted to use the paraslash scheduler.
43 - Various alsa-related fixes, mostly for the raspberry pi.
44 - Many scheduler improvements and cleanups.
45 - The test suite has been extended to include sanity checks
46 for the generated man pages.
47 - ao_writer fixes. This writer was in a quite bad shape. Many
48 serious bugs have been fixed.
49 - new audiod command: version.
50 - Minor improvements to the bitstream API.
51 - The cpsi command now prints a meaningful error message if
52 none of the given patterns matched any audio file.

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

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

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

137 --------------------------------------
138 0.4.13 (2013-07-29) "spectral gravity"
139 --------------------------------------
140
141 One more 0.4.x release before the API-breaking changes for 0.5.0 go
142 in. The main features of this release are the ogg/opus audio format,
143 and UTF-8 support, but it includes also tons of other improvements
144 and fixes all over the place.
145
146 - New audio format: ogg/opus.
147 - UTF8 support for para_gui and the mp3 audio format handler.
148 - Scheduler improvements and fixes.
149 - The obsolete gettimeofday() function has been replaced
150 by clock_gettime() on systems which support it.
151 - Speed and usability improvements for para_gui.
152 - para_client now restores the fd flags of stdin and stdout
153 on shutdown.
154 - Improved manual pages.
155 - Consistent version strings for all executables.
156 - Reduced dependencies on generated files result in fewer
157 recompilations on changes.
158 - Performance improvements for the compress filter.
159 - Improved downloads web page.
160
161 -----------------------------------------
162 0.4.12 (2012-12-20) "volatile relativity"
163 -----------------------------------------
164 The new command line player, the resample filter, ALSA support for
165 para_fade, and the improved build system are the highlights of this
166 release which probably marks the end of the 0.4.x series.
167
168 - The afh receiver and the para_play executable.
169 - The resample filter: A sample rate converter based on
170 libsamplerate.
171 - The "versions" directory has been removed from the master
172 branch. The tarballs of the old releases are now available
173 in the new "releases" branch.
174 - Overhaul of the build system: All generated files are now
175 written to the "build" directory.
176 - The modular mixer API and the alsa mixer.
177 - Minor fixes for the osx writer.
178
179 --------------------------------------
180 0.4.11 (2012-07-20) "mutual diversity"
181 --------------------------------------
182
183 The major feature in this release is the new sideband API for
184 client-server communication. This API will be used exclusively starting
185 with 0.5.0, which breaks backward compatibility but allows to get rid
186 of quite some compatibility code. Other noteworthy changes include
187 decoder latency improvements and a long-standing bug fix for the
188 ALSA writer.
189
190 - Sideband connections: If both para_server and para_client
191 support this feature, data is sent as a multiplexed stream.
192 - The --no_default_filters option of para_filter has been
193 removed.
194 - Several fixes and latency improvements to various decoders.
195 - The ALSA writer now limits the prebuffer time to 500ms.
196 - Documentation improvements.
197 - Overhaul of the command_util.sh script.
198 - Fixes for some minor problems found by the clang analyzer.
199 - Compiles (almost) without warnings on gcc-3.
200 - Robustness improvements of the buffer tree code.
201
202 ------------------------------------------
203 0.4.10 (2012-03-30) "heterogeneous vacuum"
204 ------------------------------------------
205
206 Nothing earth-shaking in this release, but quite a few usability
207 improvements and the usual mix of cleanups and fixes.
208
209 - The --no_default_filters option of para_filter has been
210 deprecated. It still works but has no effect and will be
211 removed in the next version.
212 - para_gui now prints also the stderr output of the executing
213 command in the bottom window.
214 - Cleanup and consolidation of the various wrappers for
215 write(), writev(), send() and friends.
216 - The obscure error messages on mmap() failures have been
217 replaced by meaningful messages. This affects mainly
218 para_afh.
219 - para_audioc: Cleanups and memory leak fixes.
220 - Test 0004-server no longer fails if para_server is not
221 being built.
222 - New configure options: --with-id3tag-{headers,libs}.
223
224 -------------------------------------
225 0.4.9 (2011-12-06) "hybrid causality"
226 -------------------------------------
227
228 Support for another audio format, interactive mode for para_client
229 and para_audiod and many small improvements/fixes all over the place.
230
231 - Support for flac, the free lossless audio codec.
232 - Fix for an endless loop in the mp3 decoder for certain
233 (corrupt) mp3 files.
234 - When executed without specifying a command, para_client
235 and para_audioc start an interactive shell (requires
236 libreadline being installed). The interactive mode offers
237 full tab completion and command line history.
238 - autogen.sh now detects a distcc setup and adjusts the
239 parameter for the -j option of make accordingly.
240 - Shared memory areas are no longer restricted to 64K. We now
241 detect the maximal size of a shared memory area at runtime.
242 - cleanup of the internal uptime API.
243 - para_server prefaults the mmapped audio file to avoid
244 delays on slow media.
245 - A new test for the test-suite that exercises the
246 communication between para_server and para_audiod.
247 - The alsa writer eats up less CPU cycles when configured to
248 use the DMIX plugin.
249 - Simplified and unified receiver code.
250 - Makefile cleanups.
251 - Commands which print a list of matching audio files now
252 emit a meaningful error message if no audio file matched the
253 given pattern(s).
254
255 --------------------------------------
256 0.4.8 (2011-08-19) "nested assignment"
257 --------------------------------------
258
259 Gcrypt support, the overhauled osx writer and regex format specifiers
260 are the highlights of this release.
261
262 - support for libgcrypt as a drop-in replacement for openssl.
263 Run configure --enable-cryptolib=gcrypt to link against
264 libgcrypt. The two crypto implementations are compatible to
265 each other, i.e. a para_client executable linked against
266 gcrypt can connect to para_server linked against libssl
267 and vice versa.
268 - Rewrite of the osx writer (output plugin for Mac OS).
269 - audiod: The format specifier for receivers, filters and
270 writers is now treated as a regular expression. This allows
271 to replace 5 lines in the config file (one for each audio
272 format) by one single line. See the manual for details.
273 - The *.cmdline.[ch] files are no longer contained in the released
274 tarballs. This reduces the size of the tarballs but requires
275 gengetopt to build the tarball.
276 - Compiles cleanly also with llvm/clang.
277 - Corrupt mp3 files are handled more gracefully.
278 - The alsa writer uses poll fds instead of computing timeouts.
279 - Cleanup of the generic writer API.
280 - sched: Optimized zero timeouts.
281 - vss timeout cleanups.
282 - oggdec fixes and improvements.
283
284 --------------------------------------
285 0.4.7 (2011-06-01) "infinite rollback"
286 --------------------------------------
287
288 The new ao writer, support for ssh RSA keys and a couple of other
289 enhancements.
290
291 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
292 platforms through the libao audio library.
293 - Support for RSA keys generated with ssh-keygen.
294 - configure: improved options for ogg/vorbis/speex.
295 - The git version reported by --version always matches HEAD.
296 - The autogen script detects the number of processors and
297 runs a parallel make if possible.
298 - Major cleanup of the crypto API.
299 - Documentation updates.
300
301 ------------------------------------------
302 0.4.6 (2011-03-31) "deterministic entropy"
303 ------------------------------------------
304
305 Lots of ogg/vorbis improvements, the new test suite, enhancements
306 for para_gui and a fair amount of other bug fixes.
307
308 - For DCCP/OGG streams the audio file header is only sent once
309 at the beginning of the stream rather than periodically
310 every five seconds. This reduces network traffic and the
311 FEC group size.
312 - The vorbis comment header is replaced by an empty dummy header
313 before the header is sent over the network. This also results in
314 less network traffic and smaller FEC groups.
315 - The new "test" make target allows to perform some sanity checks prior
316 to installing the package.
317 - ogg timing fixes and performance improvements
318 - Scheduler improvements
319 - Proper exit codes for para_write
320 - para_gui: New option --theme to select a startup theme. Several
321 other improvements and fixes.
322 - aacdec error message cleanups
323 - simplified color error handling
324
325 --------------------------------------------
326 0.4.5 (2010-12-17) "symmetric randomization"
327 --------------------------------------------
328
329 Bug fixes, internal cleanups and variable-sized FEC slices.
330
331 - Contains a fix for an invalid-free-bug in the ogg audio format
332 handler code.
333 - Switching off the DCCP sender works again.
334 - para_audiod handles crashes of para_server more robustly.
335 - Internal scheduler and writer cleanups.
336 - Reduced latency due to variable-sized FEC slices.
337 - Improved documentation and error diagnostics.
338 - The build of para_server is now optional, allowing the build
339 to succeed in case libosl is not installed.
340
341 ------------------------------------------
342 0.4.4 (2010-08-06) "persistent regularity"
343 ------------------------------------------
344
345 Support for yet another audio format, para_write improvements and
346 bug fixes.
347
348 - Support for the speex codec.
349 - Support for sample formats other than 16 bit little endian.
350 - error2.h is now created by a perl script which speeds up configure
351 considerably.
352 - Fix a bug in the aac decoder which could lead to segfaults in
353 para_filter/para_audiod.
354 - Fixes for autoconf-2.66.
355
356 ----------------------------------------
357 0.4.3 (2010-07-05) "imaginary radiation"
358 ----------------------------------------
359
360 Many improvements for the DCCP and the UDP transport, the new user
361 manual and the usual mix of bug fixes and internal improvements.
362
363 - FEC support for the DCCP sender (Gerrit Renker). The new
364 --dccp_max_slice_size, --dccp_data_slices_per_group and
365 --dccp_slices_per_group options can be used to set the FEC
366 parameters for the DCCP transport.
367 - DNS lookups for UDP targets (Gerrit Renker).
368 - The new user manual replaces the README, README.afs, REQUIREMENTS
369 and INSTALL documents.
370 - Fix an end-of-file detection bug in the oggdec filter.
371 - The new nonblock API.
372 - Both options of the oggdec filter have been removed.
373 - New debug mode for the internal scheduler.
374
375 ------------------------------------------
376 0.4.2 (2010-04-23) "associative expansion"
377 ------------------------------------------
378
379 It's been some time since the last release, but finally here is
380 paraslash-0.4.2. The bulk of the changes comes from the new buffer
381 tree API, but there are changes all over the tree. Mainly performance
382 and usability improvements, but also quite some bug fixes.
383
384 - The new buffer tree API.
385 - DCCP: Support for CCID negotiation (Gerrit Renker).
386 - UDP robustness fixes.
387 - The --bufsize option for mp3dec is gone as it no longer makes sense
388 for the new buffer tree API.
389 - Fix audible buffer underruns for wma streams.
390 - The alsa writer no longer prints meaningless underrun durations.
391 - audiod: Defaults work also for udp streams. If no filter is
392 given for an audio format that is received via upd, fecdec is
393 automatically added as the first filter (along with the decoder).
394
395 ---------------------------------------
396 0.4.1 (2009-12-22) "concurrent horizon"
397 ---------------------------------------
398
399 Support for another audio format, minor feature enhancements and lots of bug
400 fixes. All fixes that have been accumulated in the maint branch (in particular
401 those mentionened in the 0.3.6 release notes) appear in this release as well.
402
403 - wma support.
404 - new afh option: --human to activate human-readable output.
405 - new server/audiod option: --log-timing to print timing information.
406 - build system improvements.
407 - source code documentation updates.
408
409 -------------------------------------
410 0.3.6 (2009-12-07) "cubic continuity"
411 -------------------------------------
412
413 Quite a few bugs have been found and fixed since 0.3.5, so here's
414 another 0.3.x release. No new features.
415
416 - Always check return value of malloc().
417 - ogg vorbis/FEC: Do not write garbage after the audio file header.
418 - exit if root privileges could not be dropped.
419 - FEC: Fix computation of extra slices.
420 - oss: Fix check for empty input buffer.
421 - Avoid buffer underruns due to filter chain output buffer constraints.
422 - server: Fix assignment of afs_pid.
423 - Don't panic if the afs database contains unknown audio formats.
424 - http/dccp: Do not send the audio file header twice.
425 - FEC: Timing improvements.
426
427 ----------------------------------------------
428 0.4.0 (2009-11-10) "simultaneous independence"
429 ----------------------------------------------
430
431 Two significant changes which require the new version number: The
432 improved authentication dialog and the fact that the database code
433 has been moved to a library, libosl. To use the new version, you have
434 to generate new RSA keys, see INSTALL for details. A shell script is
435 provided for conversion of the 0.3 database to the new 0.4 format.
436
437 - stronger crypto for client authentication
438 - the database code has been moved to a library
439 - improved status item handling
440 - cleanup of the build system
441 - The "-V" option now also prints the git version
442 - the new parser-friendly listing mode for the ls and stat commands
443 - mandatory rc4 encryption
444 - major audio format handler cleanups
445 - (id3,...) tags are no longer stored as a combined string in the database
446 - new mood methods: artist_matches, title_matches, comment_matches,
447 album_matches, year_maches, year.
448
449 --------------------------------------------
450 0.3.5 (2009-09-21) "symplectic separability"
451 --------------------------------------------
452
453 Full client support for *BSD Unixes, complete re-write of the ogg
454 vorbis audio format handler, various improvements all over the place
455 and the usual mix of bugfixes. This release marks the end of the 0.3
456 series if no serious problems show up.
457
458 - the new oss writer (supported on *BSD and Linux)
459 - rewrite of the ogg vorbis audio format handler. It's
460 recommended to replace the chunk tables of existing ogg
461 vorbis files in the afs database by re-adding these files
462 with "add -f".
463 - support for netmask subsets (Gerrit Renker)
464 - the new prebuffer filter
465 - improved signal handling
466 - variable fec output buffer size
467 - improved FEC timing fixes audible buffer underruns in UDP mode
468 - --log_color actually works
469 - new ls option: -d (print dates as seconds after the epoch)
470 - update to gengetopt 2.22.2
471 - support for RSA keys of size > 512 bits
472 - new option "mixer_channel" for para_fade
473
474 -----------------------------------------
475 0.3.4 (2009-05-07) "elliptic inheritance"
476 -----------------------------------------
477
478 The new udp sender, forward error correction, colored logs and various
479 other improvements. As the udp sender does not depend on any special
480 libraries, it is built unconditionally.
481
482 - The udp sender replaces the ortp sender. The new code uses forward
483 error correction to protect against packet losses. Many thanks to
484 Gerrit Renker for providing ipv6 support.
485 - The default port for udp streaming now defaults to 8000, like
486 for the http and the dccp senders/receivers.
487 - Loglevels are now specified as symbolic names, e.g.
488 "--loglevel info".
489 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
490 - para_server/para_audiod: Color support for log messages.
491 - new options for mp3dec: --ignore-crc, --bufsize
492 - new audiod option: --config-file.
493 - gengetopt cleanups.
494 - Improved help/man pages: The documentation of para_audiod,
495 para_recv, para_filter and para_write now also contains
496 all options of the available receivers/filters/writers. The
497 man page of para_fade contains a description of the different
498 modes of operation.
499 - More source code documentation.
500 - vss timing fixes.
501
502 --------------------------------------------
503 0.3.3 (2008-12-01) "axiomatic perspectivity"
504 --------------------------------------------
505
506 Internal code cleanups, bug fixes, improved tag handling and the new
507 amplification filter.
508
509 - para_server uses the generic scheduling code.
510 - overhaul of the virtual streaming system.
511 - mp3: id3 version 2 support via libid3tag (optional)
512 - ogg: vorbis comment support.
513 - aac meta info support.
514 - mp3 audio format handler cleanups.
515 - new filter: "amp" to amplify the amplitude of the audio stream
516 - new status item/database entry: amplification. It is
517 used by the amp filter to pre-amplify the audio stream.
518 - fix a close-without-open bug in para_write.
519 - fix a bug in com_init() which was introduced in 0.3.2.
520 - better error diagnostics for para_client.
521
522 -----------------------------------------
523 0.3.2 (2008-04-11) "probabilistic parity"
524 -----------------------------------------
525
526 The new para_afh executable, scheduling and documentation improvements.
527
528 - new ls option: -lc (list chunk table)
529 - new executable: para_afh, the stand-alone audio file handler tool
530 - afs commands can send output more than SHMMAX (32MB on Linux). This
531 also reduces the memory usage of commands that produce large amounts
532 of output.
533 - major scheduler and audiod cleanups.
534 - more detailed and much nicer man pages.
535
536 ---------------------------------------
537 0.3.1 (2008-02-23) "liquid interaction"
538 ---------------------------------------
539
540 A mix of cleanups, bug fixes, improvements, and some new features. No
541 significant changes to the new database (osl) code, which is generally
542 a good sign.
543
544 - Share some similar/duplicate code between the http and the
545 dccp sender.
546 - Generic access control lists for paraslash senders.
547 - dccp sender: Access control lists, connection limiting and support
548 for the allow,deny,on,off,help sender commands.
549 - The default dccp port changed from 5001 to 8000 (suggested by
550 Gerrit Renker).
551 - para_server starts even if not all public keys could be loaded.
552 - Audiod performance improvements.
553 - fix a bug in the "off" command of the http sender.
554 - fix some fd and memory leaks.
555 - Update to gengetopt-2.22.
556
557 -------------------------------------
558 0.3.0 (2008-01-12) "solar saturation"
559 -------------------------------------
560
561 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
562
563
564 Usually one might expect lots of new features AND a big increase in size
565 for a major release like this.
566
567 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
568 ever. The decrease in size is mostly due to the removal of some
569 graphical tools (which were only quick hacks anyway). But also the
570 fact that the mysql code is gone cuts down the size a bit.
571
572 Being independent of mysql comes at a cost: The fact that paraslash
573 now contains its own database (the object storage layer, osl) increases
574 the (stripped) binary size of para_server by ~50K on i386.
575
576 - no more restrictions on unique basenames.
577 - independent of mysql: The new self-contained object
578 storage layer (osl) replaces the mysql database.
579 - New executable para_fsck: Check integrity of osl tables.
580 - Lyrics support.
581 - Reliable audio file move/rename detection.
582 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
583 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
584 Solaris (sparc64).
585 - the new osl-based audio file selector (afs) replaces the random,
586 the playlist and the mysql selector of paraslash-0.2.x.
587 - IPv6 support (thanks to Gerrit Renker).
588 - paraslash-0.2.x streams are now called "moods". Writing
589 0.3.x-mood definitions should be both easier and more
590 powerful than writing 0.2.x-stream definitions.
591 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
592 been removed. The world is a better place without them. However,
593 para_gui is still there.
594 - afs tracks audio file selection also in playlist mode.
595 - few easy-to-use afs commands replace the many not-so-easy-to-use
596 mysql commands (and are available also in playlist mode).
597 - Improved error subsystem.
598 - The earth-shaking new logo.
599
600 -----------------------------------------
601 0.2.17 (2007-11-20) "isotropic threshold"
602 -----------------------------------------
603
604 Mainly bugfixes and cleanups in this version which marks the end of
605 the 0.2.x series if no serious bugs show up after the release.
606
607 - mysql_selector: fix a locking bug.
608 - universal chunk queueing.
609 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
610 to Gerrit Renker).
611 - be more carful wrt. signed vs. unsigned argument passing.
612 - cleanup error.h and fix some references to invalid error
613 codes.
614 - update to gengetopt-2.21.
615 - update to ortp-0.13.1.
616 - autoconf: extend checks for headers, library functions and
617 compiler characteristics.
618 - Fix streaming of large mp3 files.
619 - Fix an off-by-one bug in playlist handling.
620
621 --------------------------------------
622 0.2.16 (2007-04-05) "neural discharge"
623 --------------------------------------
624
625 The main change in this release is the major audio format handler
626 cleanup which removes some similar/duplicate code and makes it easier
627 to implement plugins for other audio formats. Of course, the usual mix
628 of other improvements/changes/bugfixes also made it into the release.
629
630 - simplified audio format handlers (most of the handling functions
631 were moved one layer up to the virtual streaming system).
632 - para_server uses mmap to read audio files
633 - repositioning of mp3 streams is much faster, in particular for
634 jumping near the end of large mp3 files.
635 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
636 and AFS_WRITE.
637 - fix a bug in para_filter that caused decoding of aac files
638 to start only after a few seconds.
639 - fix osx_writer hangs
640 - simplified dccp code (thanks to Gerrit Renker)
641 - the compress filter works also on big endian systems (ppc)
642
643 -----------------------------------------
644 0.2.15 (2007-02-16) "inductive resonance"
645 -----------------------------------------
646
647 Minor improvements, more documentation and a bunch of bug fixes.
648
649 - para_server: The server.users file is only read once on server
650 startup rather than for each connection
651 - mp3dec: Fix decoding of corrupt mp3 files
652 - afs (audio file sender) is now called vss (virtual streaming
653 system). Consequently, the permission flags specified in
654 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
655 become VSS_READ and VSS_WRITE respectively.
656 - para_audiod/para_filter: Fix a bug that caused the last chunk
657 of audio data not being written under certain circumstances
658 - audiod: compute the difference of server time and local time
659 correctly
660 - para_server/para_audiod: Fix some memory leaks
661 - documentation improvements
662 - configure.ac: fix checks for para_krell
663 - new man pages
664
665 -------------------------------------------
666 0.2.14 (2006-10-15) "transient singularity"
667 -------------------------------------------
668
669 The only major enhancement of this version is the osx writer which completes
670 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
671 until now for reasons beyond the scope of this changelog entry.
672
673 - new output plugin for Mac Os: the osx writer
674 - rename configure command line options from --enable-xxx-headers to
675 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
676 - configure: new command line options: --with-mad-headers,
677 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
678 - some robustness fixes
679 - dymamic audio format recognition for audiod
680 - para_server: new command line option: --autoplay_delay
681 - para_audiod: new command line option: --clock_diff_count
682
683 ---------------------------------------
684 0.2.13 (2006-07-14) "sonic convolution"
685 ---------------------------------------
686
687 A bunch of new features and core changes.
688
689 - the new paraslash scheduler, short and sweet.
690 - Support for m4a/mp4 files via the new aac audio format
691 handler/filter (requires libfaad).
692 - each writer has its own command line parser, just like
693 para_recv and para_filter.
694 - para_client and para_audioc use the error subsystem
695 - writers are integrated in para_audiod (currently linux-only)
696 - para_client is integrated in para_audiod
697 - random/playlist selector: improved info strings
698 - new audiod commands: tasks, kill
699 - update to libortp-0.10.1
700 - para_fade: wake time defaults to 8 hours from now
701 - update to autoconf-2.60
702
703 ------------------------------------------
704 0.2.12 (2006-05-12) "oriented abstraction"
705 ------------------------------------------
706
707 Many user-visible changes in this release and lots of new
708 features:
709
710
711 - the new optional dccp sender/receiver. It uses the datagram
712 congestion control protocol. You'll need a fairly new kernel
713 for this.
714 - paraslash works on Mac OS X (thanks to Gerd Becker)
715 - para_play renamed to para_write
716 - modular output plugin design (writers) for para_write
717 - new file_writer output plugin for para_write
718 - compress filter speed improvements
719 - update to libortp-0.9.1
720 - update to gengetopt-2.17rc
721 - para_client no longer depends on libreadline (as the
722 code for the interactive mode was removed).
723 - gcc-2-95 is no longer a supported compiler. It may still
724 work, but it gets no more testing.
725 - the tarball no longer contains the screenshot images which
726 reduces its size quite a bit.
727 - configure: new command line options: --enable-mysql-headers
728 and --enable-mysql-libs
729
730 ------------------------------------
731 0.2.11 (2006-03-11) "atomic duality"
732 ------------------------------------
733
734 Here it is, the first paraslash release developed with git. There
735 are fairly many user-visible changes in this release. As two out of
736 the three "database tools" of paraslash don't use a database at all,
737 they are now called "audio file selectors" instead.
738
739
740 - the cdt command (change database tool) becomes chs (change
741 selector)
742 - no more colon separators: The syntax of some options of
743 para_audiod and para_filter have changed. Use --help for
744 more info (and some examples).
745 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
746 - switch from cvs to git (should've done that earlier)
747 - the new ipc subsystem
748 - new audio file selector: playlist
749 - para_server: the dopey selector is now called "random",
750 and is the default selector. Use the --selector option to
751 choose another selector at startup, or the chs command to
752 change the selector at runtime.
753 - X86_64 fixes (thanks to Steffen Klassert)
754 - para_play fixes
755
756 --------------------------------------
757 0.2.10 (2006-02-17) "cyclic attractor"
758 --------------------------------------
759
760 Huge documentation update, a scrollable window for para_gui, ortp
761 improvements, and of course many small fixes not mentioned here.
762 The diffstat below is rather misleading as most insertions are due
763 to the new source documentation.
764
765 - autoconf cleanup
766 - para_server also uses the new error subsystem
767 - lots of new documentation (UTSL)
768 - gui improvements:
769 - keysyms for cursor keys and for next/previous page keys
770 - scrollable output window
771 - new internal commands: scroll up/down, page up/down
772 - fix color of command output.
773 - ortp: the --chunk_time and --header flags are no longer needed
774 for para_recv/para_audiod as this information is now encoded in
775 each rtp packet sent by para_server.
776
777 -------------------------------------------
778 0.2.9 (2006-01-24) "progressive turbulence"
779 -------------------------------------------
780
781 Internal audiod receivers/filters, the new error subsystem and
782 a lot of small improvements.
783
784 - para_recv and para_filter are integrated into the para_audiod
785 binary, i.e. audiod no longer spawns a new process for
786 each receiver/filter. As para_recv and para_filter might be
787 useful as standalone programs, they still get built (linked
788 against the same object files that are also used for audiod).
789 - further ortp timing improvements should reduce the CPU usage
790 of the ortp receiver.
791 - improved audio grabbing. The 'grab' command of para_audiod
792 has its own set of command line options. Read the output of
793 "para_audioc help grab" for more info.
794 - oggdec: configurable input prebuffer size.
795 - the new error subsystem gives better error diagnostics
796 and reduces code size.
797
798 -----------------------------------------
799 0.2.8 (2006-01-02) "dynamic accumulation"
800 -----------------------------------------
801
802 The new modular filter design and the para_play-hangs bugfix.
803
804 - new executable: para_filter. It combines para_mp3dec,
805 para_oggdec and para_compress. It also adds a further filter
806 type, wav, that just inserts a wave header at the desired point
807 of the filter chain. All 'piping' is done in-memory (i.e. no
808 read/write operations are used).
809 - para_play: fix a stupid bug that caused it to hang under
810 certain circumstances.
811
812 -------------------------------------------
813 0.2.7 (2006-12-27) "transparent invariance"
814 -------------------------------------------
815
816 Not many user-visible changes but a fair amount of internal improvements.
817
818
819 - The http sender buffers data if it can not be sent
820 out immediately (because the socket is not writable). This
821 should prevent para_server from shutting down the connection
822 too early on a loaded network.
823 - para_play also prebuffers data if it is told to start at a
824 future time by the --start_time option.
825 - The return of para_recv: It combines para_ortp_recv and
826 para_http_recv. Use the --receiver option to switch between
827 the two. para_recv builds without libortp, but contains
828 only the http receiver in this case.
829 - update to ortp 0.8.1. As this ortp release contains incompatible
830 changes, para_recv-0.2.7 won't link against older ortp libs.
831 - improved ortp timings.
832 - use of gcc-extensions that #define away for non-gcc and
833 gcc < 3.0.
834
835 -------------------------------------------
836 0.2.6 (2005-10-29) "recursive compensation"
837 -------------------------------------------
838
839 Transparent session encryption (uses openssl's Alleged RC4 cipher),
840 the internal find command and several other improvements and cleanups.
841
842 - Encrypt the session if encryption is requested by the client
843 (default for para_client 0.2.6). This is backwards
844 compatible, so older clients can still connect to para_server
845 0.2.6. Use the new client option --plain to request an
846 uncrypted session (off by default, must be set to on in
847 order to connect to para_server 0.2.x with 0 <= x <= 5).
848 - para_server uses an internal function to locate audio files
849 rather than calling find(1). The server option
850 --mysql_audio_file_dir replaces --mysql_find_cmd.
851 - documentation update
852 - man pages
853 - header file cleanup
854 - para_client code cleanup
855 - para_gui: faster display of output of display commands
856
857 ------------------------------------------
858 0.2.5 (2005-10-13) "aggressive resolution"
859 ------------------------------------------
860
861 This release adds internal senders, i.e. no more external programs are
862 spawned for sending out the audio data. There are two different senders
863 available: The http sender and the ortp sender (former para_send which
864 is no longer needed).
865
866 The new sender code has a plugin-like design so it can be easily
867 extended should there be be any future need for supporting another
868 network streaming protocol. All senders are completely independent of
869 each other. In particular, the http and the ortp sender can operate
870 in parallel.
871
872 - new server command: sender to control senders at runtime.
873 Read the output of "para_server -h" and "para_client help
874 sender" for more information.
875 - para_recv renamed to para_ortp_recv
876 - new executable: para_http_recv, a simple command line
877 http receiver.
878 - major afs/mp3/ogg code simplifications due to internal
879 senders.
880 - ogg timing improvements
881 - fix several minor memory leaks (found by valgrind)
882 - empty stream definitions work again
883 - com_ne(): ignore errors on remove
884 - audiod: fix segfault on server restart
885
886 ---------------------------------------
887 0.2.4 (2005-09-21) "toxic anticipation"
888 ---------------------------------------
889
890 Several small improvements, fixes and the new grab command.
891
892 - audiod:
893 - new command: "grab" to grab the output of the stream reader
894 or any filters. Read the output of "para_audioc help grab"
895 for more information.
896 - fix memory leak
897 - code cleanup
898 - audioc: new command line option: --bufsize to specify a
899 buffer size different from the default size 8192.
900 - improved error diagnostics for para_play.
901 - new configure option: --enable-ssldir so search for openssl in
902 non-standard places
903 - sdl_gui: Make it look nice again for 1024x768
904 - server: report total size of memory allocated with sbrk by malloc,
905 new command line option: --announce_time
906
907 -----------------------------------------
908 0.2.3 (2005-09-01) "hydrophilic movement"
909 -----------------------------------------
910
911 Two new executables and major feature enhancements.
912
913 - audiod filters: It is now possible to specify arbitrary many
914 (including none) filters for each supported audio
915 format. This can be used e.g. for normalizing volume,
916 transforming or grabbing the audio stream, or for using
917 visualizers. Read the output of "para_audiod -h" for the
918 syntax of the new --filter_cmd option.
919 - new executable: para_play, a tiny alsa player. It
920 can play wave files or raw pcm (16 bit little endian)
921 from stdin.
922 - new executable: para_compress, a dynamic range compressor
923 intended to keep audio output at a consistent volume. Derived
924 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
925 - audiod: New option: --stream_delay. This can be used in
926 a local network to syncronize the audio output of all
927 clients that play the same stream.
928
929 ------------------------------------------
930 0.2.2 (2005-08-19) "tangential excitation"
931 ------------------------------------------
932
933 Mostly internal changes in this release, but also some new commands
934 for the mysql database tool.
935
936 - cleanup exec.c, fix para_exec bug
937 - compile time loglevel (log messages below the given level
938 won't be compiled in, which reduces the size of the
939 resulting binaries)
940 - new log macros that shorten the size of the source code.
941 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
942 to send only zeros. With this workaround, para_audioc works
943 again.
944 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
945 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
946 (new entry), "snp" (set numplayed). Read the manual for more
947 information.
948
949 ---------------------------------------
950 0.2.1 (2005-08-15) "surreal experience"
951 ---------------------------------------
952
953 Here comes paraslash-0.2.1. It contains a couple of new features and,
954 surprise, only minor bug fixes.
955
956 - kill noisy mp3 debug message
957 - cleanup of the build system
958 - para_server and para_client directly use the crypto routines
959 of the openssl library rather than invoking the openssl command
960 line utitlity
961 - server/audiod: new option --user to switch to the given user
962 when invoked as root. Read the output of "para_server -h" for
963 more information.
964 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
965 status. Default: "para_audioc stat"
966 - sdl_gui: new option --pic_cmd to be used to download the picture.
967 Default: "para_client pic"
968 - audiod: 5 slots ought to be enough for everybody
969 - audiod: new status item: Uptime, kill hup command
970
971 ------------------------------------------
972 0.2.0 (2005-08-06) "distributed diffusion"
973 ------------------------------------------
974
975 After several month of increased development activity, paraslash-0.2.0
976 has arrived. It contains many new features and is much more
977 self-contained than the old 0.1.x series. Enjoy!
978
979
980 - para_server: fix hang on song change and crash on sighup.
981 Speed up mysql queries. The DIR_LIKE macro is gone.
982 - new executables: para_audiod, the local audio daemon that
983 starts playback (uses SCM_CREDENTIALS socket magic) and
984 para_audioc, the corresponding client.
985 - new executables: para_mp3dec/para_oggdec, two really teensy
986 decoders. para_mp3dec is based on libmad, para_oggdec requires
987 libvorbisfile.
988 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
989 they are now called para_send and para_recv respectively.
990 - documentation updates
991 - para_gui is themable. For now there is the default theme that
992 looks as before and the simple theme: blue and easy.
993 - gui: audio streaming is now handled by audiod. Time display shows
994 playback time rather than streaming time
995 - slider: update to libzmw-0.2.0
996 - para_krell: fix crash on server shutdown
997 - switch from gzip to bzip2
998
999 ----------------------------------------
1000 0.1.7 (2005-04-18) "melting penetration"
1001 ----------------------------------------
1002
1003 The main change in this release is clearly the oggvorbis rewrite,
1004 but there are also lots of smaller changes. If you intend to use both
1005 the mp3 and the ogg plugin, it is recommended to use software mixing,
1006 e.g. the dmix plugin which is provided by ALSA.
1007
1008 - new executables: para_ovsend and para_ovrecv for sending/receiving
1009 oggvorbis files via rtp. Requires the open rtp library. Get it at
1010 http://www.linphone.org/ortp/
1011 - rewrite of the ogg_vorbis core code
1012 - configure detects libzmw and, if detected, includes
1013 para_slider to the list of binaries to be built by make
1014 - server stream writers read from their associated fifo rather
1015 than from stdin
1016 - slider: two new sliders, lastplayed and numplayed
1017 - fix nasty double free bug which caused random segfaults in case of
1018 mp3 files with invalid header information
1019 - gui: new command line option: --stream_timeout=seconds to
1020 deactivate a slot if it is idle for that many seconds (default=`5')
1021 - diffstats
1022
1023 ---------------------------------------
1024 0.1.6 (2005-03-05) "asymptotic balance"
1025 ---------------------------------------
1026
1027 Only little user-visible changes in this release. Mainly bugfixes and
1028 core code cleanup. This is probably the most stable version ever if you
1029 stick to mp3...
1030
1031 - fix several memory leaks
1032 - rename default name of mysql database from "music" to "paraslash".
1033 Use para_server's --mysql_database option if you do not want to
1034 rename your old database.
1035 - rework ogg vorbis code
1036 - make update command work on mysql servers with LOCAL_INFILE
1037 disabled
1038 - gui: improved stream I/O (slots)
1039 - simplified audio format API
1040 - para_pob_ogg is gone
1041
1042 ------------------------------------
1043 0.1.5 (2004-12-31) "opaque eternity"
1044 ------------------------------------
1045
1046 Let's slide gently into the new year.
1047
1048 - new: para_slider (not built automatically, type "make
1049 para_slider" to build). A toy for those who always felt that
1050 creating stream definitions is difficult. See screenshots,
1051 README and FEATURES for more info.
1052 - improved signal handling. Fixes server segfault on SIGHUP
1053 for linux kernels newer than Aug 24 2004 and makes para_gui
1054 race-free.
1055 - reload database tool on SIGHUP
1056 - improved help message for sl
1057 - do not log "broken pipe" messages as errors. They are
1058 perfectly ok.
1059 - fix wrong error message on permission errors
1060
1061 -----------------------------------------
1062 0.1.4 (2004-12-19) "tunneling transition"
1063 -----------------------------------------
1064
1065 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1066 Hopefully, most of them got wiped out with this release. Some
1067 enhancements went also in.
1068
1069 - improved error diagnostics for all commands
1070 - stradd/picadd: overwrite previous contents if entry already
1071 exists, rather than returning errors
1072 - stradd: use current stream if invoked without args
1073 - faster (and hopefully more stable) ogg-vorbis handling
1074 - para_krell: reap children to avoid zombie-flooding in case
1075 no server is running
1076 - si: report also server pid
1077 - server: don't busy-loop if dbtool reports only invalid files.
1078 - gui: CTRL+C works again, fix stream_read command line option
1079 - fix pic_add, hist
1080 - fix mysql dbtool startup in case no database exists
1081 - many small fixes and cleanups
1082
1083 ---------------------------------------
1084 0.1.3: (2004-12-10) "vanishing inertia"
1085 ---------------------------------------
1086
1087 Starting from this release, the database tools are integrated in the
1088 server binary. This decreases server startup time, reduces code size
1089 and speeds up database commands. However, the layout of the underlying
1090 mysql database changed only slightly and 0.1.3 should be backwards
1091 compatible in that respect.
1092
1093 Visible changes:
1094
1095 - If mysql is not detected at compile time, or fails to init
1096 at runtime, fall back to the dopey database tool which should
1097 always work.
1098 - para_dbtool and dbtool.conf are gone. All mysql specific
1099 options are read from server.conf and are prefixed by 'mysql_'.
1100 - new command: cdt (change database tool)
1101 - new command line option: dbtool (choose startup database tool)
1102 - The name of current stream is now stored in the database,
1103 so paraslash remembers its current stream when restarted.
1104 - new command: csp (change stream and play)
1105 - para_gui also reports current database tool and server uptime
1106
1107 -------------------------------------------
1108 0.1.2: (2004-11-28) "spherical fluctuation"
1109 -------------------------------------------
1110
1111 Point release before the big dbtool changes go in.
1112
1113 - dbtool: rename ca to cam (copy all meta data). It now also
1114 copies numplayed and lastplayed time as well as the picture
1115 id.
1116 - fix endless-loop-bug caused by mp3 files with invalid header
1117
1118 -----------------------------------------
1119 0.1.1: (2004-11-05) "floating atmosphere"
1120 -----------------------------------------

1140 -----------------------------------------
1141
1142 - rename projectname from icc to paraslash (play, archive, rate
1143 and stream large audio sets happily)
1144 - paraslash is no longer restricted to one particular audio
1145 streaming software
1146 - new dbtool commands (stradd, strq, strdel) for easy stream
1147 managment w/o configuration file. That obsoletes stream_defs
1148 file/config option for dbtool.
1149 - picadd accepts jpeg data from stdin
1150 - new server commands: ps (select previous stream), sc (song change)
1151 - new default pictures for sdl_gui
1152 - gui: new key_map option for binding commands and internal
1153 functions to arbitrary keys, nice help screen, rip out
1154 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1155 show silly logo on startup
1156 - new executables: para_fade for fading volume, para_dbadm for
1157 manipulating attributes

1166
1167 - kick icecast in favour of poc. That removes some races and reduces

1171 - gui can start decoder (see config options). Further new gui
1172 commands: refresh (^L), jmp (F1-F10)
1173 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1174 terminates gui. This fixes dead instances consuming memory
1175 continuously.

1177 - fix pid_list races (by removing pid_list)
1178 - codename funnies
