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

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

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

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

1122
1123 - rename projectname from icc to paraslash (play, archive, rate
1124 and stream large audio sets happily)
1125 - paraslash is no longer restricted to one particular audio
1126 streaming software
1127 - new dbtool commands (stradd, strq, strdel) for easy stream
1128 managment w/o configuration file. That obsoletes stream_defs
1129 file/config option for dbtool.
1130 - picadd accepts jpeg data from stdin
1131 - new server commands: ps (select previous stream), sc (song change)
1132 - new default pictures for sdl_gui
1133 - gui: new key_map option for binding commands and internal
1134 functions to arbitrary keys, nice help screen, rip out
1135 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1136 show silly logo on startup
1137 - new executables: para_fade for fading volume, para_dbadm for
1138 manipulating attributes

1147
1148 - kick icecast in favour of poc. That removes some races and reduces

1152 - gui can start decoder (see config options). Further new gui
1153 commands: refresh (^L), jmp (F1-F10)
1154 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1155 terminates gui. This fixes dead instances consuming memory

1159 - codename funnies
