5 0.5.2 (2014-04-11) "orthogonal interior"
6 ----------------------------------------
7
8 The new sync filter, the AES_CTR128 stream cipher and the overhauled
9 network code are the highlights of this release. It also includes a
10 fair number of smaller fixes and improvements not mentioned here.
11
12 - The new sync filter synchronizes playback between multiple
13 clients.
14 - Connections between para_server and para_client are now
15 encrypted by means of AES rather than RC4 if both sides
16 support it. RC4 is still available as a fallback. This
17 feature is fully transparent, i.e. no command line options
18 are necessary, and a client linked against openssl can
19 speak with a server linked against libgcrypt and vice versa.
20 - Major cleanup of the networking subsystem.
21 - Improvements to para_fade: the new set mode, multi-channel
22 initial volumes, better error logging.
23 - The man pages of para_audiod, para_filter, para_recv, and
24 para_write contain the relevant options for receivers, filters,
25 writers. This broke in 0.5.0.
26 - ogg/vorbis latency improvements.
27 - Improved user manual.
28 - Minor fixes to avoid clang warnings.

34 0.5.1 (2013-12-20) "temporary implication"
35 ------------------------------------------
36
37 Lots of fixes and improvements all over the place, and a major overhaul
38 of the build system.
39
40 - Audiod improvements and fixes.
41 - Buffer tree robustness improvements.
42 - Cleanup of the mood subsystem.
43 - Fixes and cleanups for the flac decoder.
44 - Latency improvements for the ogg/opus decoder.
45 - Crypto support is now optional. On systems without
46 openssl/gcrypt, the build succeeds but para_server,
47 para_audiod, para_client won't be built.
48 - The build system now works for cross-compile setups.
49 - The dependency tree has been flattened, which speeds up
50 builds and avoids to recreate the man pages on every change.
51 - The error code helper has been rewritten from perl to C,
52 which further improves build time.
53 - Many small bugs in the build system have been identified
54 and fixed.

60 0.5.0 (2013-08-23) "invertible validity"
61 ----------------------------------------
62
63 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
64
65 - The sideband compatibility code has been removed, hence
66 sideband connections (introduced in 0.4.11) are now mandatory.
67 - Addblob commands can produce output.
68 - The stat command no longer sends garbage when para_server was
69 compiled against libgcrypt.
70 - Dependencies for gengetopt files are computed automatically.
71 This eliminates a constant source of build bugs.
72 - The setatt command now accepts file name patterns rather than only
73 path names.
74 - overview.pdf is now based on dia, a simple diagram creation program.
75 The new version is much more detailed and contains descriptions of
76 the various programs of the paraslash package.
77 - The separator of all multi-word options has been changed from
78 underscore to dash. For example --log_color becomes --log-color.
79 - Overhauled web pages and the new logo.

85 0.4.13 (2013-07-29) "spectral gravity"
86 --------------------------------------
87
88 One more 0.4.x release before the API-breaking changes for 0.5.0 go
89 in. The main features of this release are the ogg/opus audio format,
90 and UTF-8 support, but it includes also tons of other improvements
91 and fixes all over the place.
92
93 - New audio format: ogg/opus.
94 - UTF8 support for para_gui and the mp3 audio format handler.
95 - Scheduler improvements and fixes.
96 - The obsolete gettimeofday() function has been replaced
97 by clock_gettime() on systems which support it.
98 - Speed and usability improvements for para_gui.
99 - para_client now restores the fd flags of stdin and stdout
100 on shutdown.
101 - Improved manual pages.
102 - Consistent version strings for all executables.
103 - Reduced dependencies on generated files result in fewer
104 recompilations on changes.
105 - Performance improvements for the compress filter.
106 - Improved downloads web page.
107
108 -----------------------------------------
109 0.4.12 (2012-12-20) "volatile relativity"
110 -----------------------------------------
111 The new command line player, the resample filter, ALSA support for
112 para_fade, and the improved build system are the highlights of this
113 release which probably marks the end of the 0.4.x series.
114
115 - The afh receiver and the para_play executable.
116 - The resample filter: A sample rate converter based on
117 libsamplerate.
118 - The "versions" directory has been removed from the master
119 branch. The tarballs of the old releases are now available
120 in the new "releases" branch.
121 - Overhaul of the build system: All generated files are now
122 written to the "build" directory.
123 - The modular mixer API and the alsa mixer.
124 - Minor fixes for the osx writer.
125
126 --------------------------------------
127 0.4.11 (2012-07-20) "mutual diversity"
128 --------------------------------------
129
130 The major feature in this release is the new sideband API for
131 client-server communication. This API will be used exclusively starting
132 with 0.5.0, which breaks backward compatibility but allows to get rid
133 of quite some compatibility code. Other noteworthy changes include
134 decoder latency improvements and a long-standing bug fix for the
135 ALSA writer.
136
137 - Sideband connections: If both para_server and para_client
138 support this feature, data is sent as a multiplexed stream.
139 - The --no_default_filters option of para_filter has been
140 removed.
141 - Several fixes and latency improvements to various decoders.
142 - The ALSA writer now limits the prebuffer time to 500ms.
143 - Documentation improvements.
144 - Overhaul of the command_util.sh script.
145 - Fixes for some minor problems found by the clang analyzer.
146 - Compiles (almost) without warnings on gcc-3.
147 - Robustness improvements of the buffer tree code.
148
149 ------------------------------------------
150 0.4.10 (2012-03-30) "heterogeneous vacuum"
151 ------------------------------------------
152
153 Nothing earth-shaking in this release, but quite a few usability
154 improvements and the usual mix of cleanups and fixes.
155
156 - The --no_default_filters option of para_filter has been
157 deprecated. It still works but has no effect and will be
158 removed in the next version.
159 - para_gui now prints also the stderr output of the executing
160 command in the bottom window.
161 - Cleanup and consolidation of the various wrappers for
162 write(), writev(), send() and friends.
163 - The obscure error messages on mmap() failures have been
164 replaced by meaningful messages. This affects mainly
165 para_afh.
166 - para_audioc: Cleanups and memory leak fixes.
167 - Test 0004-server no longer fails if para_server is not
168 being built.
169 - New configure options: --with-id3tag-{headers,libs}.
170
171 -------------------------------------
172 0.4.9 (2011-12-06) "hybrid causality"
173 -------------------------------------
174
175 Support for another audio format, interactive mode for para_client
176 and para_audiod and many small improvements/fixes all over the place.
177
178 - Support for flac, the free lossless audio codec.
179 - Fix for an endless loop in the mp3 decoder for certain
180 (corrupt) mp3 files.
181 - When executed without specifying a command, para_client
182 and para_audioc start an interactive shell (requires
183 libreadline being installed). The interactive mode offers
184 full tab completion and command line history.
185 - autogen.sh now detects a distcc setup and adjusts the
186 parameter for the -j option of make accordingly.
187 - Shared memory areas are no longer restricted to 64K. We now
188 detect the maximal size of a shared memory area at runtime.
189 - cleanup of the internal uptime API.
190 - para_server prefaults the mmapped audio file to avoid
191 delays on slow media.
192 - A new test for the test-suite that exercises the
193 communication between para_server and para_audiod.
194 - The alsa writer eats up less CPU cycles when configured to
195 use the DMIX plugin.
196 - Simplified and unified receiver code.
197 - Makefile cleanups.
198 - Commands which print a list of matching audio files now
199 emit a meaningful error message if no audio file matched the
200 given pattern(s).
201
202 --------------------------------------
203 0.4.8 (2011-08-19) "nested assignment"
204 --------------------------------------
205
206 Gcrypt support, the overhauled osx writer and regex format specifiers
207 are the highlights of this release.
208
209 - support for libgcrypt as a drop-in replacement for openssl.
210 Run configure --enable-cryptolib=gcrypt to link against
211 libgcrypt. The two crypto implementations are compatible to
212 each other, i.e. a para_client executable linked against
213 gcrypt can connect to para_server linked against libssl
214 and vice versa.
215 - Rewrite of the osx writer (output plugin for Mac OS).
216 - audiod: The format specifier for receivers, filters and
217 writers is now treated as a regular expression. This allows
218 to replace 5 lines in the config file (one for each audio
219 format) by one single line. See the manual for details.
220 - The *.cmdline.[ch] files are no longer contained in the released
221 tarballs. This reduces the size of the tarballs but requires
222 gengetopt to build the tarball.
223 - Compiles cleanly also with llvm/clang.
224 - Corrupt mp3 files are handled more gracefully.
225 - The alsa writer uses poll fds instead of computing timeouts.
226 - Cleanup of the generic writer API.
227 - sched: Optimized zero timeouts.
228 - vss timeout cleanups.
229 - oggdec fixes and improvements.
230
231 --------------------------------------
232 0.4.7 (2011-06-01) "infinite rollback"
233 --------------------------------------
234
235 The new ao writer, support for ssh RSA keys and a couple of other
236 enhancements.
237
238 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
239 platforms through the libao audio library.
240 - Support for RSA keys generated with ssh-keygen.
241 - configure: improved options for ogg/vorbis/speex.
242 - The git version reported by --version always matches HEAD.
243 - The autogen script detects the number of processors and
244 runs a parallel make if possible.
245 - Major cleanup of the crypto API.
246 - Documentation updates.
247
248 ------------------------------------------
249 0.4.6 (2011-03-31) "deterministic entropy"
250 ------------------------------------------
251
252 Lots of ogg/vorbis improvements, the new test suite, enhancements
253 for para_gui and a fair amount of other bug fixes.
254
255 - For DCCP/OGG streams the audio file header is only sent once
256 at the beginning of the stream rather than periodically
257 every five seconds. This reduces network traffic and the
258 FEC group size.
259 - The vorbis comment header is replaced by an empty dummy header
260 before the header is sent over the network. This also results in
261 less network traffic and smaller FEC groups.
262 - The new "test" make target allows to perform some sanity checks prior
263 to installing the package.
264 - ogg timing fixes and performance improvements
265 - Scheduler improvements
266 - Proper exit codes for para_write
267 - para_gui: New option --theme to select a startup theme. Several
268 other improvements and fixes.
269 - aacdec error message cleanups
270 - simplified color error handling
271
272 --------------------------------------------
273 0.4.5 (2010-12-17) "symmetric randomization"
274 --------------------------------------------
275
276 Bug fixes, internal cleanups and variable-sized FEC slices.
277
278 - Contains a fix for an invalid-free-bug in the ogg audio format
279 handler code.
280 - Switching off the DCCP sender works again.
281 - para_audiod handles crashes of para_server more robustly.
282 - Internal scheduler and writer cleanups.
283 - Reduced latency due to variable-sized FEC slices.
284 - Improved documentation and error diagnostics.
285 - The build of para_server is now optional, allowing the build
286 to succeed in case libosl is not installed.
287
288 ------------------------------------------
289 0.4.4 (2010-08-06) "persistent regularity"
290 ------------------------------------------
291
292 Support for yet another audio format, para_write improvements and
293 bug fixes.
294
295 - Support for the speex codec.
296 - Support for sample formats other than 16 bit little endian.
297 - error2.h is now created by a perl script which speeds up configure
298 considerably.
299 - Fix a bug in the aac decoder which could lead to segfaults in
300 para_filter/para_audiod.
301 - Fixes for autoconf-2.66.
302
303 ----------------------------------------
304 0.4.3 (2010-07-05) "imaginary radiation"
305 ----------------------------------------
306
307 Many improvements for the DCCP and the UDP transport, the new user
308 manual and the usual mix of bug fixes and internal improvements.
309
310 - FEC support for the DCCP sender (Gerrit Renker). The new
311 --dccp_max_slice_size, --dccp_data_slices_per_group and
312 --dccp_slices_per_group options can be used to set the FEC
313 parameters for the DCCP transport.
314 - DNS lookups for UDP targets (Gerrit Renker).
315 - The new user manual replaces the README, README.afs, REQUIREMENTS
316 and INSTALL documents.
317 - Fix an end-of-file detection bug in the oggdec filter.
318 - The new nonblock API.
319 - Both options of the oggdec filter have been removed.
320 - New debug mode for the internal scheduler.
321
322 ------------------------------------------
323 0.4.2 (2010-04-23) "associative expansion"
324 ------------------------------------------
325
326 It's been some time since the last release, but finally here is
327 paraslash-0.4.2. The bulk of the changes comes from the new buffer
328 tree API, but there are changes all over the tree. Mainly performance
329 and usability improvements, but also quite some bug fixes.
330
331 - The new buffer tree API.
332 - DCCP: Support for CCID negotiation (Gerrit Renker).
333 - UDP robustness fixes.
334 - The --bufsize option for mp3dec is gone as it no longer makes sense
335 for the new buffer tree API.
336 - Fix audible buffer underruns for wma streams.
337 - The alsa writer no longer prints meaningless underrun durations.
338 - audiod: Defaults work also for udp streams. If no filter is
339 given for an audio format that is received via upd, fecdec is
340 automatically added as the first filter (along with the decoder).
341
342 ---------------------------------------
343 0.4.1 (2009-12-22) "concurrent horizon"
344 ---------------------------------------
345
346 Support for another audio format, minor feature enhancements and lots of bug
347 fixes. All fixes that have been accumulated in the maint branch (in particular
348 those mentionened in the 0.3.6 release notes) appear in this release as well.
349
350 - wma support.
351 - new afh option: --human to activate human-readable output.
352 - new server/audiod option: --log-timing to print timing information.
353 - build system improvements.
354 - source code documentation updates.
355
356 -------------------------------------
357 0.3.6 (2009-12-07) "cubic continuity"
358 -------------------------------------
359
360 Quite a few bugs have been found and fixed since 0.3.5, so here's
361 another 0.3.x release. No new features.
362
363 - Always check return value of malloc().
364 - ogg vorbis/FEC: Do not write garbage after the audio file header.
365 - exit if root privileges could not be dropped.
366 - FEC: Fix computation of extra slices.
367 - oss: Fix check for empty input buffer.
368 - Avoid buffer underruns due to filter chain output buffer constraints.
369 - server: Fix assignment of afs_pid.
370 - Don't panic if the afs database contains unknown audio formats.
371 - http/dccp: Do not send the audio file header twice.
372 - FEC: Timing improvements.
373
374 ----------------------------------------------
375 0.4.0 (2009-11-10) "simultaneous independence"
376 ----------------------------------------------
377
378 Two significant changes which require the new version number: The
379 improved authentication dialog and the fact that the database code
380 has been moved to a library, libosl. To use the new version, you have
381 to generate new RSA keys, see INSTALL for details. A shell script is
382 provided for conversion of the 0.3 database to the new 0.4 format.
383
384 - stronger crypto for client authentication
385 - the database code has been moved to a library
386 - improved status item handling
387 - cleanup of the build system
388 - The "-V" option now also prints the git version
389 - the new parser-friendly listing mode for the ls and stat commands
390 - mandatory rc4 encryption
391 - major audio format handler cleanups
392 - (id3,...) tags are no longer stored as a combined string in the database
393 - new mood methods: artist_matches, title_matches, comment_matches,
394 album_matches, year_maches, year.
395
396 --------------------------------------------
397 0.3.5 (2009-09-21) "symplectic separability"
398 --------------------------------------------
399
400 Full client support for *BSD Unixes, complete re-write of the ogg
401 vorbis audio format handler, various improvements all over the place
402 and the usual mix of bugfixes. This release marks the end of the 0.3
403 series if no serious problems show up.
404
405 - the new oss writer (supported on *BSD and Linux)
406 - rewrite of the ogg vorbis audio format handler. It's
407 recommended to replace the chunk tables of existing ogg
408 vorbis files in the afs database by re-adding these files
409 with "add -f".
410 - support for netmask subsets (Gerrit Renker)
411 - the new prebuffer filter
412 - improved signal handling
413 - variable fec output buffer size
414 - improved FEC timing fixes audible buffer underruns in UDP mode
415 - --log_color actually works
416 - new ls option: -d (print dates as seconds after the epoch)
417 - update to gengetopt 2.22.2
418 - support for RSA keys of size > 512 bits
419 - new option "mixer_channel" for para_fade
420
421 -----------------------------------------
422 0.3.4 (2009-05-07) "elliptic inheritance"
423 -----------------------------------------
424
425 The new udp sender, forward error correction, colored logs and various
426 other improvements. As the udp sender does not depend on any special
427 libraries, it is built unconditionally.
428
429 - The udp sender replaces the ortp sender. The new code uses forward
430 error correction to protect against packet losses. Many thanks to
431 Gerrit Renker for providing ipv6 support.
432 - The default port for udp streaming now defaults to 8000, like
433 for the http and the dccp senders/receivers.
434 - Loglevels are now specified as symbolic names, e.g.
435 "--loglevel info".
436 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
437 - para_server/para_audiod: Color support for log messages.
438 - new options for mp3dec: --ignore-crc, --bufsize
439 - new audiod option: --config-file.
440 - gengetopt cleanups.
441 - Improved help/man pages: The documentation of para_audiod,
442 para_recv, para_filter and para_write now also contains
443 all options of the available receivers/filters/writers. The
444 man page of para_fade contains a description of the different
445 modes of operation.
446 - More source code documentation.
447 - vss timing fixes.
448
449 --------------------------------------------
450 0.3.3 (2008-12-01) "axiomatic perspectivity"
451 --------------------------------------------
452
453 Internal code cleanups, bug fixes, improved tag handling and the new
454 amplification filter.
455
456 - para_server uses the generic scheduling code.
457 - overhaul of the virtual streaming system.
458 - mp3: id3 version 2 support via libid3tag (optional)
459 - ogg: vorbis comment support.
460 - aac meta info support.
461 - mp3 audio format handler cleanups.
462 - new filter: "amp" to amplify the amplitude of the audio stream
463 - new status item/database entry: amplification. It is
464 used by the amp filter to pre-amplify the audio stream.
465 - fix a close-without-open bug in para_write.
466 - fix a bug in com_init() which was introduced in 0.3.2.
467 - better error diagnostics for para_client.
468
469 -----------------------------------------
470 0.3.2 (2008-04-11) "probabilistic parity"
471 -----------------------------------------
472
473 The new para_afh executable, scheduling and documentation improvements.
474
475 - new ls option: -lc (list chunk table)
476 - new executable: para_afh, the stand-alone audio file handler tool
477 - afs commands can send output more than SHMMAX (32MB on Linux). This
478 also reduces the memory usage of commands that produce large amounts
479 of output.
480 - major scheduler and audiod cleanups.
481 - more detailed and much nicer man pages.
482
483 ---------------------------------------
484 0.3.1 (2008-02-23) "liquid interaction"
485 ---------------------------------------
486
487 A mix of cleanups, bug fixes, improvements, and some new features. No
488 significant changes to the new database (osl) code, which is generally
489 a good sign.
490
491 - Share some similar/duplicate code between the http and the
492 dccp sender.
493 - Generic access control lists for paraslash senders.
494 - dccp sender: Access control lists, connection limiting and support
495 for the allow,deny,on,off,help sender commands.
496 - The default dccp port changed from 5001 to 8000 (suggested by
497 Gerrit Renker).
498 - para_server starts even if not all public keys could be loaded.
499 - Audiod performance improvements.
500 - fix a bug in the "off" command of the http sender.
501 - fix some fd and memory leaks.
502 - Update to gengetopt-2.22.
503
504 -------------------------------------
505 0.3.0 (2008-01-12) "solar saturation"
506 -------------------------------------
507
508 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
509
510
511 Usually one might expect lots of new features AND a big increase in size
512 for a major release like this.
513
514 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
515 ever. The decrease in size is mostly due to the removal of some
516 graphical tools (which were only quick hacks anyway). But also the
517 fact that the mysql code is gone cuts down the size a bit.
518
519 Being independent of mysql comes at a cost: The fact that paraslash
520 now contains its own database (the object storage layer, osl) increases
521 the (stripped) binary size of para_server by ~50K on i386.
522
523 - no more restrictions on unique basenames.
524 - independent of mysql: The new self-contained object
525 storage layer (osl) replaces the mysql database.
526 - New executable para_fsck: Check integrity of osl tables.
527 - Lyrics support.
528 - Reliable audio file move/rename detection.
529 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
530 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
531 Solaris (sparc64).
532 - the new osl-based audio file selector (afs) replaces the random,
533 the playlist and the mysql selector of paraslash-0.2.x.
534 - IPv6 support (thanks to Gerrit Renker).
535 - paraslash-0.2.x streams are now called "moods". Writing
536 0.3.x-mood definitions should be both easier and more
537 powerful than writing 0.2.x-stream definitions.
538 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
539 been removed. The world is a better place without them. However,
540 para_gui is still there.
541 - afs tracks audio file selection also in playlist mode.
542 - few easy-to-use afs commands replace the many not-so-easy-to-use
543 mysql commands (and are available also in playlist mode).
544 - Improved error subsystem.
545 - The earth-shaking new logo.
546
547 -----------------------------------------
548 0.2.17 (2007-11-20) "isotropic threshold"
549 -----------------------------------------
550
551 Mainly bugfixes and cleanups in this version which marks the end of
552 the 0.2.x series if no serious bugs show up after the release.
553
554 - mysql_selector: fix a locking bug.
555 - universal chunk queueing.
556 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
557 to Gerrit Renker).
558 - be more carful wrt. signed vs. unsigned argument passing.
559 - cleanup error.h and fix some references to invalid error
560 codes.
561 - update to gengetopt-2.21.
562 - update to ortp-0.13.1.
563 - autoconf: extend checks for headers, library functions and
564 compiler characteristics.
565 - Fix streaming of large mp3 files.
566 - Fix an off-by-one bug in playlist handling.
567
568 --------------------------------------
569 0.2.16 (2007-04-05) "neural discharge"
570 --------------------------------------
571
572 The main change in this release is the major audio format handler
573 cleanup which removes some similar/duplicate code and makes it easier
574 to implement plugins for other audio formats. Of course, the usual mix
575 of other improvements/changes/bugfixes also made it into the release.
576
577 - simplified audio format handlers (most of the handling functions
578 were moved one layer up to the virtual streaming system).
579 - para_server uses mmap to read audio files
580 - repositioning of mp3 streams is much faster, in particular for
581 jumping near the end of large mp3 files.
582 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
583 and AFS_WRITE.
584 - fix a bug in para_filter that caused decoding of aac files
585 to start only after a few seconds.
586 - fix osx_writer hangs
587 - simplified dccp code (thanks to Gerrit Renker)
588 - the compress filter works also on big endian systems (ppc)
589
590 -----------------------------------------
591 0.2.15 (2007-02-16) "inductive resonance"
592 -----------------------------------------
593
594 Minor improvements, more documentation and a bunch of bug fixes.
595
596 - para_server: The server.users file is only read once on server
597 startup rather than for each connection
598 - mp3dec: Fix decoding of corrupt mp3 files
599 - afs (audio file sender) is now called vss (virtual streaming
600 system). Consequently, the permission flags specified in
601 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
602 become VSS_READ and VSS_WRITE respectively.
603 - para_audiod/para_filter: Fix a bug that caused the last chunk
604 of audio data not being written under certain circumstances
605 - audiod: compute the difference of server time and local time
606 correctly
607 - para_server/para_audiod: Fix some memory leaks
608 - documentation improvements
609 - configure.ac: fix checks for para_krell
610 - new man pages
611
612 -------------------------------------------
613 0.2.14 (2006-10-15) "transient singularity"
614 -------------------------------------------
615
616 The only major enhancement of this version is the osx writer which completes
617 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
618 until now for reasons beyond the scope of this changelog entry.
619
620 - new output plugin for Mac Os: the osx writer
621 - rename configure command line options from --enable-xxx-headers to
622 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
623 - configure: new command line options: --with-mad-headers,
624 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
625 - some robustness fixes
626 - dymamic audio format recognition for audiod
627 - para_server: new command line option: --autoplay_delay
628 - para_audiod: new command line option: --clock_diff_count
629
630 ---------------------------------------
631 0.2.13 (2006-07-14) "sonic convolution"
632 ---------------------------------------
633
634 A bunch of new features and core changes.
635
636 - the new paraslash scheduler, short and sweet.
637 - Support for m4a/mp4 files via the new aac audio format
638 handler/filter (requires libfaad).
639 - each writer has its own command line parser, just like
640 para_recv and para_filter.
641 - para_client and para_audioc use the error subsystem
642 - writers are integrated in para_audiod (currently linux-only)
643 - para_client is integrated in para_audiod
644 - random/playlist selector: improved info strings
645 - new audiod commands: tasks, kill
646 - update to libortp-0.10.1
647 - para_fade: wake time defaults to 8 hours from now
648 - update to autoconf-2.60
649
650 ------------------------------------------
651 0.2.12 (2006-05-12) "oriented abstraction"
652 ------------------------------------------
653
654 Many user-visible changes in this release and lots of new
655 features:
656
657
658 - the new optional dccp sender/receiver. It uses the datagram
659 congestion control protocol. You'll need a fairly new kernel
660 for this.
661 - paraslash works on Mac OS X (thanks to Gerd Becker)
662 - para_play renamed to para_write
663 - modular output plugin design (writers) for para_write
664 - new file_writer output plugin for para_write
665 - compress filter speed improvements
666 - update to libortp-0.9.1
667 - update to gengetopt-2.17rc
668 - para_client no longer depends on libreadline (as the
669 code for the interactive mode was removed).
670 - gcc-2-95 is no longer a supported compiler. It may still
671 work, but it gets no more testing.
672 - the tarball no longer contains the screenshot images which
673 reduces its size quite a bit.
674 - configure: new command line options: --enable-mysql-headers
675 and --enable-mysql-libs
676
677 ------------------------------------
678 0.2.11 (2006-03-11) "atomic duality"
679 ------------------------------------
680
681 Here it is, the first paraslash release developed with git. There
682 are fairly many user-visible changes in this release. As two out of
683 the three "database tools" of paraslash don't use a database at all,
684 they are now called "audio file selectors" instead.
685
686
687 - the cdt command (change database tool) becomes chs (change
688 selector)
689 - no more colon separators: The syntax of some options of
690 para_audiod and para_filter have changed. Use --help for
691 more info (and some examples).
692 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
693 - switch from cvs to git (should've done that earlier)
694 - the new ipc subsystem
695 - new audio file selector: playlist
696 - para_server: the dopey selector is now called "random",
697 and is the default selector. Use the --selector option to
698 choose another selector at startup, or the chs command to
699 change the selector at runtime.
700 - X86_64 fixes (thanks to Steffen Klassert)
701 - para_play fixes
702
703 --------------------------------------
704 0.2.10 (2006-02-17) "cyclic attractor"
705 --------------------------------------
706
707 Huge documentation update, a scrollable window for para_gui, ortp
708 improvements, and of course many small fixes not mentioned here.
709 The diffstat below is rather misleading as most insertions are due
710 to the new source documentation.
711
712 - autoconf cleanup
713 - para_server also uses the new error subsystem
714 - lots of new documentation (UTSL)
715 - gui improvements:
716 - keysyms for cursor keys and for next/previous page keys
717 - scrollable output window
718 - new internal commands: scroll up/down, page up/down
719 - fix color of command output.
720 - ortp: the --chunk_time and --header flags are no longer needed
721 for para_recv/para_audiod as this information is now encoded in
722 each rtp packet sent by para_server.
723
724 -------------------------------------------
725 0.2.9 (2006-01-24) "progressive turbulence"
726 -------------------------------------------
727
728 Internal audiod receivers/filters, the new error subsystem and
729 a lot of small improvements.
730
731 - para_recv and para_filter are integrated into the para_audiod
732 binary, i.e. audiod no longer spawns a new process for
733 each receiver/filter. As para_recv and para_filter might be
734 useful as standalone programs, they still get built (linked
735 against the same object files that are also used for audiod).
736 - further ortp timing improvements should reduce the CPU usage
737 of the ortp receiver.
738 - improved audio grabbing. The 'grab' command of para_audiod
739 has its own set of command line options. Read the output of
740 "para_audioc help grab" for more info.
741 - oggdec: configurable input prebuffer size.
742 - the new error subsystem gives better error diagnostics
743 and reduces code size.
744
745 -----------------------------------------
746 0.2.8 (2006-01-02) "dynamic accumulation"
747 -----------------------------------------
748
749 The new modular filter design and the para_play-hangs bugfix.
750
751 - new executable: para_filter. It combines para_mp3dec,
752 para_oggdec and para_compress. It also adds a further filter
753 type, wav, that just inserts a wave header at the desired point
754 of the filter chain. All 'piping' is done in-memory (i.e. no
755 read/write operations are used).
756 - para_play: fix a stupid bug that caused it to hang under
757 certain circumstances.
758
759 -------------------------------------------
760 0.2.7 (2006-12-27) "transparent invariance"
761 -------------------------------------------
762
763 Not many user-visible changes but a fair amount of internal improvements.
764
765
766 - The http sender buffers data if it can not be sent
767 out immediately (because the socket is not writable). This
768 should prevent para_server from shutting down the connection
769 too early on a loaded network.
770 - para_play also prebuffers data if it is told to start at a
771 future time by the --start_time option.
772 - The return of para_recv: It combines para_ortp_recv and
773 para_http_recv. Use the --receiver option to switch between
774 the two. para_recv builds without libortp, but contains
775 only the http receiver in this case.
776 - update to ortp 0.8.1. As this ortp release contains incompatible
777 changes, para_recv-0.2.7 won't link against older ortp libs.
778 - improved ortp timings.
779 - use of gcc-extensions that #define away for non-gcc and
780 gcc < 3.0.
781
782 -------------------------------------------
783 0.2.6 (2005-10-29) "recursive compensation"
784 -------------------------------------------
785
786 Transparent session encryption (uses openssl's Alleged RC4 cipher),
787 the internal find command and several other improvements and cleanups.
788
789 - Encrypt the session if encryption is requested by the client
790 (default for para_client 0.2.6). This is backwards
791 compatible, so older clients can still connect to para_server
792 0.2.6. Use the new client option --plain to request an
793 uncrypted session (off by default, must be set to on in
794 order to connect to para_server 0.2.x with 0 <= x <= 5).
795 - para_server uses an internal function to locate audio files
796 rather than calling find(1). The server option
797 --mysql_audio_file_dir replaces --mysql_find_cmd.
798 - documentation update
799 - man pages
800 - header file cleanup
801 - para_client code cleanup
802 - para_gui: faster display of output of display commands
803
804 ------------------------------------------
805 0.2.5 (2005-10-13) "aggressive resolution"
806 ------------------------------------------
807
808 This release adds internal senders, i.e. no more external programs are
809 spawned for sending out the audio data. There are two different senders
810 available: The http sender and the ortp sender (former para_send which
811 is no longer needed).
812
813 The new sender code has a plugin-like design so it can be easily
814 extended should there be be any future need for supporting another
815 network streaming protocol. All senders are completely independent of
816 each other. In particular, the http and the ortp sender can operate
817 in parallel.
818
819 - new server command: sender to control senders at runtime.
820 Read the output of "para_server -h" and "para_client help
821 sender" for more information.
822 - para_recv renamed to para_ortp_recv
823 - new executable: para_http_recv, a simple command line
824 http receiver.
825 - major afs/mp3/ogg code simplifications due to internal
826 senders.
827 - ogg timing improvements
828 - fix several minor memory leaks (found by valgrind)
829 - empty stream definitions work again
830 - com_ne(): ignore errors on remove
831 - audiod: fix segfault on server restart
832
833 ---------------------------------------
834 0.2.4 (2005-09-21) "toxic anticipation"
835 ---------------------------------------
836
837 Several small improvements, fixes and the new grab command.
838
839 - audiod:
840 - new command: "grab" to grab the output of the stream reader
841 or any filters. Read the output of "para_audioc help grab"
842 for more information.
843 - fix memory leak
844 - code cleanup
845 - audioc: new command line option: --bufsize to specify a
846 buffer size different from the default size 8192.
847 - improved error diagnostics for para_play.
848 - new configure option: --enable-ssldir so search for openssl in
849 non-standard places
850 - sdl_gui: Make it look nice again for 1024x768
851 - server: report total size of memory allocated with sbrk by malloc,
852 new command line option: --announce_time
853
854 -----------------------------------------
855 0.2.3 (2005-09-01) "hydrophilic movement"
856 -----------------------------------------
857
858 Two new executables and major feature enhancements.
859
860 - audiod filters: It is now possible to specify arbitrary many
861 (including none) filters for each supported audio
862 format. This can be used e.g. for normalizing volume,
863 transforming or grabbing the audio stream, or for using
864 visualizers. Read the output of "para_audiod -h" for the
865 syntax of the new --filter_cmd option.
866 - new executable: para_play, a tiny alsa player. It
867 can play wave files or raw pcm (16 bit little endian)
868 from stdin.
869 - new executable: para_compress, a dynamic range compressor
870 intended to keep audio output at a consistent volume. Derived
871 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
872 - audiod: New option: --stream_delay. This can be used in
873 a local network to syncronize the audio output of all
874 clients that play the same stream.
875
876 ------------------------------------------
877 0.2.2 (2005-08-19) "tangential excitation"
878 ------------------------------------------
879
880 Mostly internal changes in this release, but also some new commands
881 for the mysql database tool.
882
883 - cleanup exec.c, fix para_exec bug
884 - compile time loglevel (log messages below the given level
885 won't be compiled in, which reduces the size of the
886 resulting binaries)
887 - new log macros that shorten the size of the source code.
888 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
889 to send only zeros. With this workaround, para_audioc works
890 again.
891 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
892 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
893 (new entry), "snp" (set numplayed). Read the manual for more
894 information.
895
896 ---------------------------------------
897 0.2.1 (2005-08-15) "surreal experience"
898 ---------------------------------------
899
900 Here comes paraslash-0.2.1. It contains a couple of new features and,
901 surprise, only minor bug fixes.
902
903 - kill noisy mp3 debug message
904 - cleanup of the build system
905 - para_server and para_client directly use the crypto routines
906 of the openssl library rather than invoking the openssl command
907 line utitlity
908 - server/audiod: new option --user to switch to the given user
909 when invoked as root. Read the output of "para_server -h" for
910 more information.
911 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
912 status. Default: "para_audioc stat"
913 - sdl_gui: new option --pic_cmd to be used to download the picture.
914 Default: "para_client pic"
915 - audiod: 5 slots ought to be enough for everybody
916 - audiod: new status item: Uptime, kill hup command
917
918 ------------------------------------------
919 0.2.0 (2005-08-06) "distributed diffusion"
920 ------------------------------------------
921
922 After several month of increased development activity, paraslash-0.2.0
923 has arrived. It contains many new features and is much more
924 self-contained than the old 0.1.x series. Enjoy!
925
926
927 - para_server: fix hang on song change and crash on sighup.
928 Speed up mysql queries. The DIR_LIKE macro is gone.
929 - new executables: para_audiod, the local audio daemon that
930 starts playback (uses SCM_CREDENTIALS socket magic) and
931 para_audioc, the corresponding client.
932 - new executables: para_mp3dec/para_oggdec, two really teensy
933 decoders. para_mp3dec is based on libmad, para_oggdec requires
934 libvorbisfile.
935 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
936 they are now called para_send and para_recv respectively.
937 - documentation updates
938 - para_gui is themable. For now there is the default theme that
939 looks as before and the simple theme: blue and easy.
940 - gui: audio streaming is now handled by audiod. Time display shows
941 playback time rather than streaming time
942 - slider: update to libzmw-0.2.0
943 - para_krell: fix crash on server shutdown
944 - switch from gzip to bzip2
945
946 ----------------------------------------
947 0.1.7 (2005-04-18) "melting penetration"
948 ----------------------------------------
949
950 The main change in this release is clearly the oggvorbis rewrite,
951 but there are also lots of smaller changes. If you intend to use both
952 the mp3 and the ogg plugin, it is recommended to use software mixing,
953 e.g. the dmix plugin which is provided by ALSA.
954
955 - new executables: para_ovsend and para_ovrecv for sending/receiving
956 oggvorbis files via rtp. Requires the open rtp library. Get it at
957 http://www.linphone.org/ortp/
958 - rewrite of the ogg_vorbis core code
959 - configure detects libzmw and, if detected, includes
960 para_slider to the list of binaries to be built by make
961 - server stream writers read from their associated fifo rather
962 than from stdin
963 - slider: two new sliders, lastplayed and numplayed
964 - fix nasty double free bug which caused random segfaults in case of
965 mp3 files with invalid header information
966 - gui: new command line option: --stream_timeout=seconds to
967 deactivate a slot if it is idle for that many seconds (default=`5')
968 - diffstats
969
970 ---------------------------------------
971 0.1.6 (2005-03-05) "asymptotic balance"
972 ---------------------------------------
973
974 Only little user-visible changes in this release. Mainly bugfixes and
975 core code cleanup. This is probably the most stable version ever if you
976 stick to mp3...
977
978 - fix several memory leaks
979 - rename default name of mysql database from "music" to "paraslash".
980 Use para_server's --mysql_database option if you do not want to
981 rename your old database.
982 - rework ogg vorbis code
983 - make update command work on mysql servers with LOCAL_INFILE
984 disabled
985 - gui: improved stream I/O (slots)
986 - simplified audio format API
987 - para_pob_ogg is gone
988
989 ------------------------------------
990 0.1.5 (2004-12-31) "opaque eternity"
991 ------------------------------------
992
993 Let's slide gently into the new year.
994
995 - new: para_slider (not built automatically, type "make
996 para_slider" to build). A toy for those who always felt that
997 creating stream definitions is difficult. See screenshots,
998 README and FEATURES for more info.
999 - improved signal handling. Fixes server segfault on SIGHUP
1000 for linux kernels newer than Aug 24 2004 and makes para_gui
1001 race-free.
1002 - reload database tool on SIGHUP
1003 - improved help message for sl
1004 - do not log "broken pipe" messages as errors. They are
1005 perfectly ok.
1006 - fix wrong error message on permission errors
1007
1008 -----------------------------------------
1009 0.1.4 (2004-12-19) "tunneling transition"
1010 -----------------------------------------
1011
1012 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1013 Hopefully, most of them got wiped out with this release. Some
1014 enhancements went also in.
1015
1016 - improved error diagnostics for all commands
1017 - stradd/picadd: overwrite previous contents if entry already
1018 exists, rather than returning errors
1019 - stradd: use current stream if invoked without args
1020 - faster (and hopefully more stable) ogg-vorbis handling
1021 - para_krell: reap children to avoid zombie-flooding in case
1022 no server is running
1023 - si: report also server pid
1024 - server: don't busy-loop if dbtool reports only invalid files.
1025 - gui: CTRL+C works again, fix stream_read command line option
1026 - fix pic_add, hist
1027 - fix mysql dbtool startup in case no database exists
1028 - many small fixes and cleanups
1029
1030 ---------------------------------------
1031 0.1.3: (2004-12-10) "vanishing inertia"
1032 ---------------------------------------
1033
1034 Starting from this release, the database tools are integrated in the
1035 server binary. This decreases server startup time, reduces code size
1036 and speeds up database commands. However, the layout of the underlying
1037 mysql database changed only slightly and 0.1.3 should be backwards
1038 compatible in that respect.
1039
1040 Visible changes:
1041
1042 - If mysql is not detected at compile time, or fails to init
1043 at runtime, fall back to the dopey database tool which should
