5 0.5.3 (to be released) "symbolic synchronization"
6 -------------------------------------------------
7
8 - Various alsa-related fixes, mostly for the raspberry pi.
9
10 ----------------------------------------
11 0.5.2 (2014-04-11) "orthogonal interior"
12 ----------------------------------------
13
14 The new sync filter, the AES_CTR128 stream cipher and the overhauled
15 network code are the highlights of this release. It also includes a
16 fair number of smaller fixes and improvements not mentioned here.
17
18 - The new sync filter synchronizes playback between multiple
19 clients.
20 - Connections between para_server and para_client are now
21 encrypted by means of AES rather than RC4 if both sides
22 support it. RC4 is still available as a fallback. This
23 feature is fully transparent, i.e. no command line options
24 are necessary, and a client linked against openssl can
25 speak with a server linked against libgcrypt and vice versa.
26 - Major cleanup of the networking subsystem.
27 - Improvements to para_fade: the new set mode, multi-channel
28 initial volumes, better error logging.
29 - The man pages of para_audiod, para_filter, para_recv, and
30 para_write contain the relevant options for receivers, filters,
31 writers. This broke in 0.5.0.
32 - ogg/vorbis latency improvements.
33 - Improved user manual.
34 - Minor fixes to avoid clang warnings.

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

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

90 --------------------------------------
91 0.4.13 (2013-07-29) "spectral gravity"
92 --------------------------------------
93
94 One more 0.4.x release before the API-breaking changes for 0.5.0 go
95 in. The main features of this release are the ogg/opus audio format,
96 and UTF-8 support, but it includes also tons of other improvements
97 and fixes all over the place.
98
99 - New audio format: ogg/opus.
100 - UTF8 support for para_gui and the mp3 audio format handler.
101 - Scheduler improvements and fixes.
102 - The obsolete gettimeofday() function has been replaced
103 by clock_gettime() on systems which support it.
104 - Speed and usability improvements for para_gui.
105 - para_client now restores the fd flags of stdin and stdout
106 on shutdown.
107 - Improved manual pages.
108 - Consistent version strings for all executables.
109 - Reduced dependencies on generated files result in fewer
110 recompilations on changes.
111 - Performance improvements for the compress filter.
112 - Improved downloads web page.
113
114 -----------------------------------------
115 0.4.12 (2012-12-20) "volatile relativity"
116 -----------------------------------------
117 The new command line player, the resample filter, ALSA support for
118 para_fade, and the improved build system are the highlights of this
119 release which probably marks the end of the 0.4.x series.
120
121 - The afh receiver and the para_play executable.
122 - The resample filter: A sample rate converter based on
123 libsamplerate.
124 - The "versions" directory has been removed from the master
125 branch. The tarballs of the old releases are now available
126 in the new "releases" branch.
127 - Overhaul of the build system: All generated files are now
128 written to the "build" directory.
129 - The modular mixer API and the alsa mixer.
130 - Minor fixes for the osx writer.
131
132 --------------------------------------
133 0.4.11 (2012-07-20) "mutual diversity"
134 --------------------------------------
135
136 The major feature in this release is the new sideband API for
137 client-server communication. This API will be used exclusively starting
138 with 0.5.0, which breaks backward compatibility but allows to get rid
139 of quite some compatibility code. Other noteworthy changes include
140 decoder latency improvements and a long-standing bug fix for the
141 ALSA writer.
142
143 - Sideband connections: If both para_server and para_client
144 support this feature, data is sent as a multiplexed stream.
145 - The --no_default_filters option of para_filter has been
146 removed.
147 - Several fixes and latency improvements to various decoders.
148 - The ALSA writer now limits the prebuffer time to 500ms.
149 - Documentation improvements.
150 - Overhaul of the command_util.sh script.
151 - Fixes for some minor problems found by the clang analyzer.
152 - Compiles (almost) without warnings on gcc-3.
153 - Robustness improvements of the buffer tree code.
154
155 ------------------------------------------
156 0.4.10 (2012-03-30) "heterogeneous vacuum"
157 ------------------------------------------
158
159 Nothing earth-shaking in this release, but quite a few usability
160 improvements and the usual mix of cleanups and fixes.
161
162 - The --no_default_filters option of para_filter has been
163 deprecated. It still works but has no effect and will be
164 removed in the next version.
165 - para_gui now prints also the stderr output of the executing
166 command in the bottom window.
167 - Cleanup and consolidation of the various wrappers for
168 write(), writev(), send() and friends.
169 - The obscure error messages on mmap() failures have been
170 replaced by meaningful messages. This affects mainly
171 para_afh.
172 - para_audioc: Cleanups and memory leak fixes.
173 - Test 0004-server no longer fails if para_server is not
174 being built.
175 - New configure options: --with-id3tag-{headers,libs}.
176
177 -------------------------------------
178 0.4.9 (2011-12-06) "hybrid causality"
179 -------------------------------------
180
181 Support for another audio format, interactive mode for para_client
182 and para_audiod and many small improvements/fixes all over the place.
183
184 - Support for flac, the free lossless audio codec.
185 - Fix for an endless loop in the mp3 decoder for certain
186 (corrupt) mp3 files.
187 - When executed without specifying a command, para_client
188 and para_audioc start an interactive shell (requires
189 libreadline being installed). The interactive mode offers
190 full tab completion and command line history.
191 - autogen.sh now detects a distcc setup and adjusts the
192 parameter for the -j option of make accordingly.
193 - Shared memory areas are no longer restricted to 64K. We now
194 detect the maximal size of a shared memory area at runtime.
195 - cleanup of the internal uptime API.
196 - para_server prefaults the mmapped audio file to avoid
197 delays on slow media.
198 - A new test for the test-suite that exercises the
199 communication between para_server and para_audiod.
200 - The alsa writer eats up less CPU cycles when configured to
201 use the DMIX plugin.
202 - Simplified and unified receiver code.
203 - Makefile cleanups.
204 - Commands which print a list of matching audio files now
205 emit a meaningful error message if no audio file matched the
206 given pattern(s).
207
208 --------------------------------------
209 0.4.8 (2011-08-19) "nested assignment"
210 --------------------------------------
211
212 Gcrypt support, the overhauled osx writer and regex format specifiers
213 are the highlights of this release.
214
215 - support for libgcrypt as a drop-in replacement for openssl.
216 Run configure --enable-cryptolib=gcrypt to link against
217 libgcrypt. The two crypto implementations are compatible to
218 each other, i.e. a para_client executable linked against
219 gcrypt can connect to para_server linked against libssl
220 and vice versa.
221 - Rewrite of the osx writer (output plugin for Mac OS).
222 - audiod: The format specifier for receivers, filters and
223 writers is now treated as a regular expression. This allows
224 to replace 5 lines in the config file (one for each audio
225 format) by one single line. See the manual for details.
226 - The *.cmdline.[ch] files are no longer contained in the released
227 tarballs. This reduces the size of the tarballs but requires
228 gengetopt to build the tarball.
229 - Compiles cleanly also with llvm/clang.
230 - Corrupt mp3 files are handled more gracefully.
231 - The alsa writer uses poll fds instead of computing timeouts.
232 - Cleanup of the generic writer API.
233 - sched: Optimized zero timeouts.
234 - vss timeout cleanups.
235 - oggdec fixes and improvements.
236
237 --------------------------------------
238 0.4.7 (2011-06-01) "infinite rollback"
239 --------------------------------------
240
241 The new ao writer, support for ssh RSA keys and a couple of other
242 enhancements.
243
244 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
245 platforms through the libao audio library.
246 - Support for RSA keys generated with ssh-keygen.
247 - configure: improved options for ogg/vorbis/speex.
248 - The git version reported by --version always matches HEAD.
249 - The autogen script detects the number of processors and
250 runs a parallel make if possible.
251 - Major cleanup of the crypto API.
252 - Documentation updates.
253
254 ------------------------------------------
255 0.4.6 (2011-03-31) "deterministic entropy"
256 ------------------------------------------
257
258 Lots of ogg/vorbis improvements, the new test suite, enhancements
259 for para_gui and a fair amount of other bug fixes.
260
261 - For DCCP/OGG streams the audio file header is only sent once
262 at the beginning of the stream rather than periodically
263 every five seconds. This reduces network traffic and the
264 FEC group size.
265 - The vorbis comment header is replaced by an empty dummy header
266 before the header is sent over the network. This also results in
267 less network traffic and smaller FEC groups.
268 - The new "test" make target allows to perform some sanity checks prior
269 to installing the package.
270 - ogg timing fixes and performance improvements
271 - Scheduler improvements
272 - Proper exit codes for para_write
273 - para_gui: New option --theme to select a startup theme. Several
274 other improvements and fixes.
275 - aacdec error message cleanups
276 - simplified color error handling
277
278 --------------------------------------------
279 0.4.5 (2010-12-17) "symmetric randomization"
280 --------------------------------------------
281
282 Bug fixes, internal cleanups and variable-sized FEC slices.
283
284 - Contains a fix for an invalid-free-bug in the ogg audio format
285 handler code.
286 - Switching off the DCCP sender works again.
287 - para_audiod handles crashes of para_server more robustly.
288 - Internal scheduler and writer cleanups.
289 - Reduced latency due to variable-sized FEC slices.
290 - Improved documentation and error diagnostics.
291 - The build of para_server is now optional, allowing the build
292 to succeed in case libosl is not installed.
293
294 ------------------------------------------
295 0.4.4 (2010-08-06) "persistent regularity"
296 ------------------------------------------
297
298 Support for yet another audio format, para_write improvements and
299 bug fixes.
300
301 - Support for the speex codec.
302 - Support for sample formats other than 16 bit little endian.
303 - error2.h is now created by a perl script which speeds up configure
304 considerably.
305 - Fix a bug in the aac decoder which could lead to segfaults in
306 para_filter/para_audiod.
307 - Fixes for autoconf-2.66.
308
309 ----------------------------------------
310 0.4.3 (2010-07-05) "imaginary radiation"
311 ----------------------------------------
312
313 Many improvements for the DCCP and the UDP transport, the new user
314 manual and the usual mix of bug fixes and internal improvements.
315
316 - FEC support for the DCCP sender (Gerrit Renker). The new
317 --dccp_max_slice_size, --dccp_data_slices_per_group and
318 --dccp_slices_per_group options can be used to set the FEC
319 parameters for the DCCP transport.
320 - DNS lookups for UDP targets (Gerrit Renker).
321 - The new user manual replaces the README, README.afs, REQUIREMENTS
322 and INSTALL documents.
323 - Fix an end-of-file detection bug in the oggdec filter.
324 - The new nonblock API.
325 - Both options of the oggdec filter have been removed.
326 - New debug mode for the internal scheduler.
327
328 ------------------------------------------
329 0.4.2 (2010-04-23) "associative expansion"
330 ------------------------------------------
331
332 It's been some time since the last release, but finally here is
333 paraslash-0.4.2. The bulk of the changes comes from the new buffer
334 tree API, but there are changes all over the tree. Mainly performance
335 and usability improvements, but also quite some bug fixes.
336
337 - The new buffer tree API.
338 - DCCP: Support for CCID negotiation (Gerrit Renker).
339 - UDP robustness fixes.
340 - The --bufsize option for mp3dec is gone as it no longer makes sense
341 for the new buffer tree API.
342 - Fix audible buffer underruns for wma streams.
343 - The alsa writer no longer prints meaningless underrun durations.
344 - audiod: Defaults work also for udp streams. If no filter is
345 given for an audio format that is received via upd, fecdec is
346 automatically added as the first filter (along with the decoder).
347
348 ---------------------------------------
349 0.4.1 (2009-12-22) "concurrent horizon"
350 ---------------------------------------
351
352 Support for another audio format, minor feature enhancements and lots of bug
353 fixes. All fixes that have been accumulated in the maint branch (in particular
354 those mentionened in the 0.3.6 release notes) appear in this release as well.
355
356 - wma support.
357 - new afh option: --human to activate human-readable output.
358 - new server/audiod option: --log-timing to print timing information.
359 - build system improvements.
360 - source code documentation updates.
361
362 -------------------------------------
363 0.3.6 (2009-12-07) "cubic continuity"
364 -------------------------------------
365
366 Quite a few bugs have been found and fixed since 0.3.5, so here's
367 another 0.3.x release. No new features.
368
369 - Always check return value of malloc().
370 - ogg vorbis/FEC: Do not write garbage after the audio file header.
371 - exit if root privileges could not be dropped.
372 - FEC: Fix computation of extra slices.
373 - oss: Fix check for empty input buffer.
374 - Avoid buffer underruns due to filter chain output buffer constraints.
375 - server: Fix assignment of afs_pid.
376 - Don't panic if the afs database contains unknown audio formats.
377 - http/dccp: Do not send the audio file header twice.
378 - FEC: Timing improvements.
379
380 ----------------------------------------------
381 0.4.0 (2009-11-10) "simultaneous independence"
382 ----------------------------------------------
383
384 Two significant changes which require the new version number: The
385 improved authentication dialog and the fact that the database code
386 has been moved to a library, libosl. To use the new version, you have
387 to generate new RSA keys, see INSTALL for details. A shell script is
388 provided for conversion of the 0.3 database to the new 0.4 format.
389
390 - stronger crypto for client authentication
391 - the database code has been moved to a library
392 - improved status item handling
393 - cleanup of the build system
394 - The "-V" option now also prints the git version
395 - the new parser-friendly listing mode for the ls and stat commands
396 - mandatory rc4 encryption
397 - major audio format handler cleanups
398 - (id3,...) tags are no longer stored as a combined string in the database
399 - new mood methods: artist_matches, title_matches, comment_matches,
400 album_matches, year_maches, year.
401
402 --------------------------------------------
403 0.3.5 (2009-09-21) "symplectic separability"
404 --------------------------------------------
405
406 Full client support for *BSD Unixes, complete re-write of the ogg
407 vorbis audio format handler, various improvements all over the place
408 and the usual mix of bugfixes. This release marks the end of the 0.3
409 series if no serious problems show up.
410
411 - the new oss writer (supported on *BSD and Linux)
412 - rewrite of the ogg vorbis audio format handler. It's
413 recommended to replace the chunk tables of existing ogg
414 vorbis files in the afs database by re-adding these files
415 with "add -f".
416 - support for netmask subsets (Gerrit Renker)
417 - the new prebuffer filter
418 - improved signal handling
419 - variable fec output buffer size
420 - improved FEC timing fixes audible buffer underruns in UDP mode
421 - --log_color actually works
422 - new ls option: -d (print dates as seconds after the epoch)
423 - update to gengetopt 2.22.2
424 - support for RSA keys of size > 512 bits
425 - new option "mixer_channel" for para_fade
426
427 -----------------------------------------
428 0.3.4 (2009-05-07) "elliptic inheritance"
429 -----------------------------------------
430
431 The new udp sender, forward error correction, colored logs and various
432 other improvements. As the udp sender does not depend on any special
433 libraries, it is built unconditionally.
434
435 - The udp sender replaces the ortp sender. The new code uses forward
436 error correction to protect against packet losses. Many thanks to
437 Gerrit Renker for providing ipv6 support.
438 - The default port for udp streaming now defaults to 8000, like
439 for the http and the dccp senders/receivers.
440 - Loglevels are now specified as symbolic names, e.g.
441 "--loglevel info".
442 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
443 - para_server/para_audiod: Color support for log messages.
444 - new options for mp3dec: --ignore-crc, --bufsize
445 - new audiod option: --config-file.
446 - gengetopt cleanups.
447 - Improved help/man pages: The documentation of para_audiod,
448 para_recv, para_filter and para_write now also contains
449 all options of the available receivers/filters/writers. The
450 man page of para_fade contains a description of the different
451 modes of operation.
452 - More source code documentation.
453 - vss timing fixes.
454
455 --------------------------------------------
456 0.3.3 (2008-12-01) "axiomatic perspectivity"
457 --------------------------------------------
458
459 Internal code cleanups, bug fixes, improved tag handling and the new
460 amplification filter.
461
462 - para_server uses the generic scheduling code.
463 - overhaul of the virtual streaming system.
464 - mp3: id3 version 2 support via libid3tag (optional)
465 - ogg: vorbis comment support.
466 - aac meta info support.
467 - mp3 audio format handler cleanups.
468 - new filter: "amp" to amplify the amplitude of the audio stream
469 - new status item/database entry: amplification. It is
470 used by the amp filter to pre-amplify the audio stream.
471 - fix a close-without-open bug in para_write.
472 - fix a bug in com_init() which was introduced in 0.3.2.
473 - better error diagnostics for para_client.
474
475 -----------------------------------------
476 0.3.2 (2008-04-11) "probabilistic parity"
477 -----------------------------------------
478
479 The new para_afh executable, scheduling and documentation improvements.
480
481 - new ls option: -lc (list chunk table)
482 - new executable: para_afh, the stand-alone audio file handler tool
483 - afs commands can send output more than SHMMAX (32MB on Linux). This
484 also reduces the memory usage of commands that produce large amounts
485 of output.
486 - major scheduler and audiod cleanups.
487 - more detailed and much nicer man pages.
488
489 ---------------------------------------
490 0.3.1 (2008-02-23) "liquid interaction"
491 ---------------------------------------
492
493 A mix of cleanups, bug fixes, improvements, and some new features. No
494 significant changes to the new database (osl) code, which is generally
495 a good sign.
496
497 - Share some similar/duplicate code between the http and the
498 dccp sender.
499 - Generic access control lists for paraslash senders.
500 - dccp sender: Access control lists, connection limiting and support
501 for the allow,deny,on,off,help sender commands.
502 - The default dccp port changed from 5001 to 8000 (suggested by
503 Gerrit Renker).
504 - para_server starts even if not all public keys could be loaded.
505 - Audiod performance improvements.
506 - fix a bug in the "off" command of the http sender.
507 - fix some fd and memory leaks.
508 - Update to gengetopt-2.22.
509
510 -------------------------------------
511 0.3.0 (2008-01-12) "solar saturation"
512 -------------------------------------
513
514 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
515
516
517 Usually one might expect lots of new features AND a big increase in size
518 for a major release like this.
519
520 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
521 ever. The decrease in size is mostly due to the removal of some
522 graphical tools (which were only quick hacks anyway). But also the
523 fact that the mysql code is gone cuts down the size a bit.
524
525 Being independent of mysql comes at a cost: The fact that paraslash
526 now contains its own database (the object storage layer, osl) increases
527 the (stripped) binary size of para_server by ~50K on i386.
528
529 - no more restrictions on unique basenames.
530 - independent of mysql: The new self-contained object
531 storage layer (osl) replaces the mysql database.
532 - New executable para_fsck: Check integrity of osl tables.
533 - Lyrics support.
534 - Reliable audio file move/rename detection.
535 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
536 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
537 Solaris (sparc64).
538 - the new osl-based audio file selector (afs) replaces the random,
539 the playlist and the mysql selector of paraslash-0.2.x.
540 - IPv6 support (thanks to Gerrit Renker).
541 - paraslash-0.2.x streams are now called "moods". Writing
542 0.3.x-mood definitions should be both easier and more
543 powerful than writing 0.2.x-stream definitions.
544 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
545 been removed. The world is a better place without them. However,
546 para_gui is still there.
547 - afs tracks audio file selection also in playlist mode.
548 - few easy-to-use afs commands replace the many not-so-easy-to-use
549 mysql commands (and are available also in playlist mode).
550 - Improved error subsystem.
551 - The earth-shaking new logo.
552
553 -----------------------------------------
554 0.2.17 (2007-11-20) "isotropic threshold"
555 -----------------------------------------
556
557 Mainly bugfixes and cleanups in this version which marks the end of
558 the 0.2.x series if no serious bugs show up after the release.
559
560 - mysql_selector: fix a locking bug.
561 - universal chunk queueing.
562 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
563 to Gerrit Renker).
564 - be more carful wrt. signed vs. unsigned argument passing.
565 - cleanup error.h and fix some references to invalid error
566 codes.
567 - update to gengetopt-2.21.
568 - update to ortp-0.13.1.
569 - autoconf: extend checks for headers, library functions and
570 compiler characteristics.
571 - Fix streaming of large mp3 files.
572 - Fix an off-by-one bug in playlist handling.
573
574 --------------------------------------
575 0.2.16 (2007-04-05) "neural discharge"
576 --------------------------------------
577
578 The main change in this release is the major audio format handler
579 cleanup which removes some similar/duplicate code and makes it easier
580 to implement plugins for other audio formats. Of course, the usual mix
581 of other improvements/changes/bugfixes also made it into the release.
582
583 - simplified audio format handlers (most of the handling functions
584 were moved one layer up to the virtual streaming system).
585 - para_server uses mmap to read audio files
586 - repositioning of mp3 streams is much faster, in particular for
587 jumping near the end of large mp3 files.
588 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
589 and AFS_WRITE.
590 - fix a bug in para_filter that caused decoding of aac files
591 to start only after a few seconds.
592 - fix osx_writer hangs
593 - simplified dccp code (thanks to Gerrit Renker)
594 - the compress filter works also on big endian systems (ppc)
595
596 -----------------------------------------
597 0.2.15 (2007-02-16) "inductive resonance"
598 -----------------------------------------
599
600 Minor improvements, more documentation and a bunch of bug fixes.
601
602 - para_server: The server.users file is only read once on server
603 startup rather than for each connection
604 - mp3dec: Fix decoding of corrupt mp3 files
605 - afs (audio file sender) is now called vss (virtual streaming
606 system). Consequently, the permission flags specified in
607 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
608 become VSS_READ and VSS_WRITE respectively.
609 - para_audiod/para_filter: Fix a bug that caused the last chunk
610 of audio data not being written under certain circumstances
611 - audiod: compute the difference of server time and local time
612 correctly
613 - para_server/para_audiod: Fix some memory leaks
614 - documentation improvements
615 - configure.ac: fix checks for para_krell
616 - new man pages
617
618 -------------------------------------------
619 0.2.14 (2006-10-15) "transient singularity"
620 -------------------------------------------
621
622 The only major enhancement of this version is the osx writer which completes
623 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
624 until now for reasons beyond the scope of this changelog entry.
625
626 - new output plugin for Mac Os: the osx writer
627 - rename configure command line options from --enable-xxx-headers to
628 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
629 - configure: new command line options: --with-mad-headers,
630 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
631 - some robustness fixes
632 - dymamic audio format recognition for audiod
633 - para_server: new command line option: --autoplay_delay
634 - para_audiod: new command line option: --clock_diff_count
635
636 ---------------------------------------
637 0.2.13 (2006-07-14) "sonic convolution"
638 ---------------------------------------
639
640 A bunch of new features and core changes.
641
642 - the new paraslash scheduler, short and sweet.
643 - Support for m4a/mp4 files via the new aac audio format
644 handler/filter (requires libfaad).
645 - each writer has its own command line parser, just like
646 para_recv and para_filter.
647 - para_client and para_audioc use the error subsystem
648 - writers are integrated in para_audiod (currently linux-only)
649 - para_client is integrated in para_audiod
650 - random/playlist selector: improved info strings
651 - new audiod commands: tasks, kill
652 - update to libortp-0.10.1
653 - para_fade: wake time defaults to 8 hours from now
654 - update to autoconf-2.60
655
656 ------------------------------------------
657 0.2.12 (2006-05-12) "oriented abstraction"
658 ------------------------------------------
659
660 Many user-visible changes in this release and lots of new
661 features:
662
663
664 - the new optional dccp sender/receiver. It uses the datagram
665 congestion control protocol. You'll need a fairly new kernel
666 for this.
667 - paraslash works on Mac OS X (thanks to Gerd Becker)
668 - para_play renamed to para_write
669 - modular output plugin design (writers) for para_write
670 - new file_writer output plugin for para_write
671 - compress filter speed improvements
672 - update to libortp-0.9.1
673 - update to gengetopt-2.17rc
674 - para_client no longer depends on libreadline (as the
675 code for the interactive mode was removed).
676 - gcc-2-95 is no longer a supported compiler. It may still
677 work, but it gets no more testing.
678 - the tarball no longer contains the screenshot images which
679 reduces its size quite a bit.
680 - configure: new command line options: --enable-mysql-headers
681 and --enable-mysql-libs
682
683 ------------------------------------
684 0.2.11 (2006-03-11) "atomic duality"
685 ------------------------------------
686
687 Here it is, the first paraslash release developed with git. There
688 are fairly many user-visible changes in this release. As two out of
689 the three "database tools" of paraslash don't use a database at all,
690 they are now called "audio file selectors" instead.
691
692
693 - the cdt command (change database tool) becomes chs (change
694 selector)
695 - no more colon separators: The syntax of some options of
696 para_audiod and para_filter have changed. Use --help for
697 more info (and some examples).
698 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
699 - switch from cvs to git (should've done that earlier)
700 - the new ipc subsystem
701 - new audio file selector: playlist
702 - para_server: the dopey selector is now called "random",
703 and is the default selector. Use the --selector option to
704 choose another selector at startup, or the chs command to
705 change the selector at runtime.
706 - X86_64 fixes (thanks to Steffen Klassert)
707 - para_play fixes
708
709 --------------------------------------
710 0.2.10 (2006-02-17) "cyclic attractor"
711 --------------------------------------
712
713 Huge documentation update, a scrollable window for para_gui, ortp
714 improvements, and of course many small fixes not mentioned here.
715 The diffstat below is rather misleading as most insertions are due
716 to the new source documentation.
717
718 - autoconf cleanup
719 - para_server also uses the new error subsystem
720 - lots of new documentation (UTSL)
721 - gui improvements:
722 - keysyms for cursor keys and for next/previous page keys
723 - scrollable output window
724 - new internal commands: scroll up/down, page up/down
725 - fix color of command output.
726 - ortp: the --chunk_time and --header flags are no longer needed
727 for para_recv/para_audiod as this information is now encoded in
728 each rtp packet sent by para_server.
729
730 -------------------------------------------
731 0.2.9 (2006-01-24) "progressive turbulence"
732 -------------------------------------------
733
734 Internal audiod receivers/filters, the new error subsystem and
735 a lot of small improvements.
736
737 - para_recv and para_filter are integrated into the para_audiod
738 binary, i.e. audiod no longer spawns a new process for
739 each receiver/filter. As para_recv and para_filter might be
740 useful as standalone programs, they still get built (linked
741 against the same object files that are also used for audiod).
742 - further ortp timing improvements should reduce the CPU usage
743 of the ortp receiver.
744 - improved audio grabbing. The 'grab' command of para_audiod
745 has its own set of command line options. Read the output of
746 "para_audioc help grab" for more info.
747 - oggdec: configurable input prebuffer size.
748 - the new error subsystem gives better error diagnostics
749 and reduces code size.
750
751 -----------------------------------------
752 0.2.8 (2006-01-02) "dynamic accumulation"
753 -----------------------------------------
754
755 The new modular filter design and the para_play-hangs bugfix.
756
757 - new executable: para_filter. It combines para_mp3dec,
758 para_oggdec and para_compress. It also adds a further filter
759 type, wav, that just inserts a wave header at the desired point
760 of the filter chain. All 'piping' is done in-memory (i.e. no
761 read/write operations are used).
762 - para_play: fix a stupid bug that caused it to hang under
763 certain circumstances.
764
765 -------------------------------------------
766 0.2.7 (2006-12-27) "transparent invariance"
767 -------------------------------------------
768
769 Not many user-visible changes but a fair amount of internal improvements.
770
771
772 - The http sender buffers data if it can not be sent
773 out immediately (because the socket is not writable). This
774 should prevent para_server from shutting down the connection
775 too early on a loaded network.
776 - para_play also prebuffers data if it is told to start at a
777 future time by the --start_time option.
778 - The return of para_recv: It combines para_ortp_recv and
779 para_http_recv. Use the --receiver option to switch between
780 the two. para_recv builds without libortp, but contains
781 only the http receiver in this case.
782 - update to ortp 0.8.1. As this ortp release contains incompatible
783 changes, para_recv-0.2.7 won't link against older ortp libs.
784 - improved ortp timings.
785 - use of gcc-extensions that #define away for non-gcc and
786 gcc < 3.0.
787
788 -------------------------------------------
789 0.2.6 (2005-10-29) "recursive compensation"
790 -------------------------------------------
791
792 Transparent session encryption (uses openssl's Alleged RC4 cipher),
793 the internal find command and several other improvements and cleanups.
794
795 - Encrypt the session if encryption is requested by the client
796 (default for para_client 0.2.6). This is backwards
797 compatible, so older clients can still connect to para_server
798 0.2.6. Use the new client option --plain to request an
799 uncrypted session (off by default, must be set to on in
800 order to connect to para_server 0.2.x with 0 <= x <= 5).
801 - para_server uses an internal function to locate audio files
802 rather than calling find(1). The server option
803 --mysql_audio_file_dir replaces --mysql_find_cmd.
804 - documentation update
805 - man pages
806 - header file cleanup
807 - para_client code cleanup
808 - para_gui: faster display of output of display commands
809
810 ------------------------------------------
811 0.2.5 (2005-10-13) "aggressive resolution"
812 ------------------------------------------
813
814 This release adds internal senders, i.e. no more external programs are
815 spawned for sending out the audio data. There are two different senders
816 available: The http sender and the ortp sender (former para_send which
817 is no longer needed).
818
819 The new sender code has a plugin-like design so it can be easily
820 extended should there be be any future need for supporting another
821 network streaming protocol. All senders are completely independent of
822 each other. In particular, the http and the ortp sender can operate
823 in parallel.
824
825 - new server command: sender to control senders at runtime.
826 Read the output of "para_server -h" and "para_client help
827 sender" for more information.
828 - para_recv renamed to para_ortp_recv
829 - new executable: para_http_recv, a simple command line
830 http receiver.
831 - major afs/mp3/ogg code simplifications due to internal
832 senders.
833 - ogg timing improvements
834 - fix several minor memory leaks (found by valgrind)
835 - empty stream definitions work again
836 - com_ne(): ignore errors on remove
837 - audiod: fix segfault on server restart
838
839 ---------------------------------------
840 0.2.4 (2005-09-21) "toxic anticipation"
841 ---------------------------------------
842
843 Several small improvements, fixes and the new grab command.
844
845 - audiod:
846 - new command: "grab" to grab the output of the stream reader
847 or any filters. Read the output of "para_audioc help grab"
848 for more information.
849 - fix memory leak
850 - code cleanup
851 - audioc: new command line option: --bufsize to specify a
852 buffer size different from the default size 8192.
853 - improved error diagnostics for para_play.
854 - new configure option: --enable-ssldir so search for openssl in
855 non-standard places
856 - sdl_gui: Make it look nice again for 1024x768
857 - server: report total size of memory allocated with sbrk by malloc,
858 new command line option: --announce_time
859
860 -----------------------------------------
861 0.2.3 (2005-09-01) "hydrophilic movement"
862 -----------------------------------------
863
864 Two new executables and major feature enhancements.
865
866 - audiod filters: It is now possible to specify arbitrary many
867 (including none) filters for each supported audio
868 format. This can be used e.g. for normalizing volume,
869 transforming or grabbing the audio stream, or for using
870 visualizers. Read the output of "para_audiod -h" for the
871 syntax of the new --filter_cmd option.
872 - new executable: para_play, a tiny alsa player. It
873 can play wave files or raw pcm (16 bit little endian)
874 from stdin.
875 - new executable: para_compress, a dynamic range compressor
876 intended to keep audio output at a consistent volume. Derived
877 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
878 - audiod: New option: --stream_delay. This can be used in
879 a local network to syncronize the audio output of all
880 clients that play the same stream.
881
882 ------------------------------------------
883 0.2.2 (2005-08-19) "tangential excitation"
884 ------------------------------------------
885
886 Mostly internal changes in this release, but also some new commands
887 for the mysql database tool.
888
889 - cleanup exec.c, fix para_exec bug
890 - compile time loglevel (log messages below the given level
891 won't be compiled in, which reduces the size of the
892 resulting binaries)
893 - new log macros that shorten the size of the source code.
894 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
895 to send only zeros. With this workaround, para_audioc works
896 again.
897 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
898 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
899 (new entry), "snp" (set numplayed). Read the manual for more
900 information.
901
902 ---------------------------------------
903 0.2.1 (2005-08-15) "surreal experience"
904 ---------------------------------------
905
906 Here comes paraslash-0.2.1. It contains a couple of new features and,
907 surprise, only minor bug fixes.
908
909 - kill noisy mp3 debug message
910 - cleanup of the build system
911 - para_server and para_client directly use the crypto routines
912 of the openssl library rather than invoking the openssl command
913 line utitlity
914 - server/audiod: new option --user to switch to the given user
915 when invoked as root. Read the output of "para_server -h" for
916 more information.
917 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
918 status. Default: "para_audioc stat"
919 - sdl_gui: new option --pic_cmd to be used to download the picture.
920 Default: "para_client pic"
921 - audiod: 5 slots ought to be enough for everybody
922 - audiod: new status item: Uptime, kill hup command
923
924 ------------------------------------------
925 0.2.0 (2005-08-06) "distributed diffusion"
926 ------------------------------------------
927
928 After several month of increased development activity, paraslash-0.2.0
929 has arrived. It contains many new features and is much more
930 self-contained than the old 0.1.x series. Enjoy!
931
932
933 - para_server: fix hang on song change and crash on sighup.
934 Speed up mysql queries. The DIR_LIKE macro is gone.
935 - new executables: para_audiod, the local audio daemon that
936 starts playback (uses SCM_CREDENTIALS socket magic) and
937 para_audioc, the corresponding client.
938 - new executables: para_mp3dec/para_oggdec, two really teensy
939 decoders. para_mp3dec is based on libmad, para_oggdec requires
940 libvorbisfile.
941 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
942 they are now called para_send and para_recv respectively.
943 - documentation updates
944 - para_gui is themable. For now there is the default theme that
945 looks as before and the simple theme: blue and easy.
946 - gui: audio streaming is now handled by audiod. Time display shows
947 playback time rather than streaming time
948 - slider: update to libzmw-0.2.0
949 - para_krell: fix crash on server shutdown
950 - switch from gzip to bzip2
951
952 ----------------------------------------
953 0.1.7 (2005-04-18) "melting penetration"
954 ----------------------------------------
955
956 The main change in this release is clearly the oggvorbis rewrite,
957 but there are also lots of smaller changes. If you intend to use both
958 the mp3 and the ogg plugin, it is recommended to use software mixing,
959 e.g. the dmix plugin which is provided by ALSA.
960
961 - new executables: para_ovsend and para_ovrecv for sending/receiving
962 oggvorbis files via rtp. Requires the open rtp library. Get it at
963 http://www.linphone.org/ortp/
964 - rewrite of the ogg_vorbis core code
965 - configure detects libzmw and, if detected, includes
966 para_slider to the list of binaries to be built by make
967 - server stream writers read from their associated fifo rather
968 than from stdin
969 - slider: two new sliders, lastplayed and numplayed
970 - fix nasty double free bug which caused random segfaults in case of
971 mp3 files with invalid header information
972 - gui: new command line option: --stream_timeout=seconds to
973 deactivate a slot if it is idle for that many seconds (default=`5')
974 - diffstats
975
976 ---------------------------------------
977 0.1.6 (2005-03-05) "asymptotic balance"
978 ---------------------------------------
979
980 Only little user-visible changes in this release. Mainly bugfixes and
981 core code cleanup. This is probably the most stable version ever if you
982 stick to mp3...
983
984 - fix several memory leaks
985 - rename default name of mysql database from "music" to "paraslash".
986 Use para_server's --mysql_database option if you do not want to
987 rename your old database.
988 - rework ogg vorbis code
989 - make update command work on mysql servers with LOCAL_INFILE
990 disabled
991 - gui: improved stream I/O (slots)
992 - simplified audio format API
993 - para_pob_ogg is gone
994
995 ------------------------------------
996 0.1.5 (2004-12-31) "opaque eternity"
997 ------------------------------------
998
999 Let's slide gently into the new year.
1000
1001 - new: para_slider (not built automatically, type "make
1002 para_slider" to build). A toy for those who always felt that
1003 creating stream definitions is difficult. See screenshots,
1004 README and FEATURES for more info.
1005 - improved signal handling. Fixes server segfault on SIGHUP
1006 for linux kernels newer than Aug 24 2004 and makes para_gui
1007 race-free.
1008 - reload database tool on SIGHUP
1009 - improved help message for sl
1010 - do not log "broken pipe" messages as errors. They are
1011 perfectly ok.
1012 - fix wrong error message on permission errors
1013
1014 -----------------------------------------
1015 0.1.4 (2004-12-19) "tunneling transition"
1016 -----------------------------------------
1017
1018 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1019 Hopefully, most of them got wiped out with this release. Some
1020 enhancements went also in.
1021
1022 - improved error diagnostics for all commands
1023 - stradd/picadd: overwrite previous contents if entry already
1024 exists, rather than returning errors
1025 - stradd: use current stream if invoked without args
1026 - faster (and hopefully more stable) ogg-vorbis handling
1027 - para_krell: reap children to avoid zombie-flooding in case
1028 no server is running
1029 - si: report also server pid
1030 - server: don't busy-loop if dbtool reports only invalid files.
1031 - gui: CTRL+C works again, fix stream_read command line option
1032 - fix pic_add, hist
1033 - fix mysql dbtool startup in case no database exists
1034 - many small fixes and cleanups
1035
1036 ---------------------------------------
1037 0.1.3: (2004-12-10) "vanishing inertia"
1038 ---------------------------------------
1039
1040 Starting from this release, the database tools are integrated in the
1041 server binary. This decreases server startup time, reduces code size
1042 and speeds up database commands. However, the layout of the underlying
1043 mysql database changed only slightly and 0.1.3 should be backwards
1044 compatible in that respect.
1045
1046 Visible changes:
1047
