4 -------------------------------------------------
5 0.5.3 (to be released) "symbolic synchronization"
6 -------------------------------------------------
7
8 - Various alsa-related fixes, mostly for the raspberry pi.
9 - The test suite has been extended to include sanity checks
10 for the generated man pages.
11 - ao_writer fixes. This writer was in a quite bad shape. Many
12 serious bugs have been fixed.
13
14 ----------------------------------------
15 0.5.2 (2014-04-11) "orthogonal interior"
16 ----------------------------------------
17
18 The new sync filter, the AES_CTR128 stream cipher and the overhauled
19 network code are the highlights of this release. It also includes a
20 fair number of smaller fixes and improvements not mentioned here.
21
22 - The new sync filter synchronizes playback between multiple
23 clients.
24 - Connections between para_server and para_client are now
25 encrypted by means of AES rather than RC4 if both sides
26 support it. RC4 is still available as a fallback. This
27 feature is fully transparent, i.e. no command line options
28 are necessary, and a client linked against openssl can
29 speak with a server linked against libgcrypt and vice versa.
30 - Major cleanup of the networking subsystem.
31 - Improvements to para_fade: the new set mode, multi-channel
32 initial volumes, better error logging.
33 - The man pages of para_audiod, para_filter, para_recv, and
34 para_write contain the relevant options for receivers, filters,
35 writers. This broke in 0.5.0.
36 - ogg/vorbis latency improvements.
37 - Improved user manual.
38 - Minor fixes to avoid clang warnings.

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

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

94 --------------------------------------
95 0.4.13 (2013-07-29) "spectral gravity"
96 --------------------------------------
97
98 One more 0.4.x release before the API-breaking changes for 0.5.0 go
99 in. The main features of this release are the ogg/opus audio format,
100 and UTF-8 support, but it includes also tons of other improvements
101 and fixes all over the place.
102
103 - New audio format: ogg/opus.
104 - UTF8 support for para_gui and the mp3 audio format handler.
105 - Scheduler improvements and fixes.
106 - The obsolete gettimeofday() function has been replaced
107 by clock_gettime() on systems which support it.
108 - Speed and usability improvements for para_gui.
109 - para_client now restores the fd flags of stdin and stdout
110 on shutdown.
111 - Improved manual pages.
112 - Consistent version strings for all executables.
113 - Reduced dependencies on generated files result in fewer
114 recompilations on changes.
115 - Performance improvements for the compress filter.
116 - Improved downloads web page.
117
118 -----------------------------------------
119 0.4.12 (2012-12-20) "volatile relativity"
120 -----------------------------------------
121 The new command line player, the resample filter, ALSA support for
122 para_fade, and the improved build system are the highlights of this
123 release which probably marks the end of the 0.4.x series.
124
125 - The afh receiver and the para_play executable.
126 - The resample filter: A sample rate converter based on
127 libsamplerate.
128 - The "versions" directory has been removed from the master
129 branch. The tarballs of the old releases are now available
130 in the new "releases" branch.
131 - Overhaul of the build system: All generated files are now
132 written to the "build" directory.
133 - The modular mixer API and the alsa mixer.
134 - Minor fixes for the osx writer.
135
136 --------------------------------------
137 0.4.11 (2012-07-20) "mutual diversity"
138 --------------------------------------
139
140 The major feature in this release is the new sideband API for
141 client-server communication. This API will be used exclusively starting
142 with 0.5.0, which breaks backward compatibility but allows to get rid
143 of quite some compatibility code. Other noteworthy changes include
144 decoder latency improvements and a long-standing bug fix for the
145 ALSA writer.
146
147 - Sideband connections: If both para_server and para_client
148 support this feature, data is sent as a multiplexed stream.
149 - The --no_default_filters option of para_filter has been
150 removed.
151 - Several fixes and latency improvements to various decoders.
152 - The ALSA writer now limits the prebuffer time to 500ms.
153 - Documentation improvements.
154 - Overhaul of the command_util.sh script.
155 - Fixes for some minor problems found by the clang analyzer.
156 - Compiles (almost) without warnings on gcc-3.
157 - Robustness improvements of the buffer tree code.
158
159 ------------------------------------------
160 0.4.10 (2012-03-30) "heterogeneous vacuum"
161 ------------------------------------------
162
163 Nothing earth-shaking in this release, but quite a few usability
164 improvements and the usual mix of cleanups and fixes.
165
166 - The --no_default_filters option of para_filter has been
167 deprecated. It still works but has no effect and will be
168 removed in the next version.
169 - para_gui now prints also the stderr output of the executing
170 command in the bottom window.
171 - Cleanup and consolidation of the various wrappers for
172 write(), writev(), send() and friends.
173 - The obscure error messages on mmap() failures have been
174 replaced by meaningful messages. This affects mainly
175 para_afh.
176 - para_audioc: Cleanups and memory leak fixes.
177 - Test 0004-server no longer fails if para_server is not
178 being built.
179 - New configure options: --with-id3tag-{headers,libs}.
180
181 -------------------------------------
182 0.4.9 (2011-12-06) "hybrid causality"
183 -------------------------------------
184
185 Support for another audio format, interactive mode for para_client
186 and para_audiod and many small improvements/fixes all over the place.
187
188 - Support for flac, the free lossless audio codec.
189 - Fix for an endless loop in the mp3 decoder for certain
190 (corrupt) mp3 files.
191 - When executed without specifying a command, para_client
192 and para_audioc start an interactive shell (requires
193 libreadline being installed). The interactive mode offers
194 full tab completion and command line history.
195 - autogen.sh now detects a distcc setup and adjusts the
196 parameter for the -j option of make accordingly.
197 - Shared memory areas are no longer restricted to 64K. We now
198 detect the maximal size of a shared memory area at runtime.
199 - cleanup of the internal uptime API.
200 - para_server prefaults the mmapped audio file to avoid
201 delays on slow media.
202 - A new test for the test-suite that exercises the
203 communication between para_server and para_audiod.
204 - The alsa writer eats up less CPU cycles when configured to
205 use the DMIX plugin.
206 - Simplified and unified receiver code.
207 - Makefile cleanups.
208 - Commands which print a list of matching audio files now
209 emit a meaningful error message if no audio file matched the
210 given pattern(s).
211
212 --------------------------------------
213 0.4.8 (2011-08-19) "nested assignment"
214 --------------------------------------
215
216 Gcrypt support, the overhauled osx writer and regex format specifiers
217 are the highlights of this release.
218
219 - support for libgcrypt as a drop-in replacement for openssl.
220 Run configure --enable-cryptolib=gcrypt to link against
221 libgcrypt. The two crypto implementations are compatible to
222 each other, i.e. a para_client executable linked against
223 gcrypt can connect to para_server linked against libssl
224 and vice versa.
225 - Rewrite of the osx writer (output plugin for Mac OS).
226 - audiod: The format specifier for receivers, filters and
227 writers is now treated as a regular expression. This allows
228 to replace 5 lines in the config file (one for each audio
229 format) by one single line. See the manual for details.
230 - The *.cmdline.[ch] files are no longer contained in the released
231 tarballs. This reduces the size of the tarballs but requires
232 gengetopt to build the tarball.
233 - Compiles cleanly also with llvm/clang.
234 - Corrupt mp3 files are handled more gracefully.
235 - The alsa writer uses poll fds instead of computing timeouts.
236 - Cleanup of the generic writer API.
237 - sched: Optimized zero timeouts.
238 - vss timeout cleanups.
239 - oggdec fixes and improvements.
240
241 --------------------------------------
242 0.4.7 (2011-06-01) "infinite rollback"
243 --------------------------------------
244
245 The new ao writer, support for ssh RSA keys and a couple of other
246 enhancements.
247
248 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
249 platforms through the libao audio library.
250 - Support for RSA keys generated with ssh-keygen.
251 - configure: improved options for ogg/vorbis/speex.
252 - The git version reported by --version always matches HEAD.
253 - The autogen script detects the number of processors and
254 runs a parallel make if possible.
255 - Major cleanup of the crypto API.
256 - Documentation updates.
257
258 ------------------------------------------
259 0.4.6 (2011-03-31) "deterministic entropy"
260 ------------------------------------------
261
262 Lots of ogg/vorbis improvements, the new test suite, enhancements
263 for para_gui and a fair amount of other bug fixes.
264
265 - For DCCP/OGG streams the audio file header is only sent once
266 at the beginning of the stream rather than periodically
267 every five seconds. This reduces network traffic and the
268 FEC group size.
269 - The vorbis comment header is replaced by an empty dummy header
270 before the header is sent over the network. This also results in
271 less network traffic and smaller FEC groups.
272 - The new "test" make target allows to perform some sanity checks prior
273 to installing the package.
274 - ogg timing fixes and performance improvements
275 - Scheduler improvements
276 - Proper exit codes for para_write
277 - para_gui: New option --theme to select a startup theme. Several
278 other improvements and fixes.
279 - aacdec error message cleanups
280 - simplified color error handling
281
282 --------------------------------------------
283 0.4.5 (2010-12-17) "symmetric randomization"
284 --------------------------------------------
285
286 Bug fixes, internal cleanups and variable-sized FEC slices.
287
288 - Contains a fix for an invalid-free-bug in the ogg audio format
289 handler code.
290 - Switching off the DCCP sender works again.
291 - para_audiod handles crashes of para_server more robustly.
292 - Internal scheduler and writer cleanups.
293 - Reduced latency due to variable-sized FEC slices.
294 - Improved documentation and error diagnostics.
295 - The build of para_server is now optional, allowing the build
296 to succeed in case libosl is not installed.
297
298 ------------------------------------------
299 0.4.4 (2010-08-06) "persistent regularity"
300 ------------------------------------------
301
302 Support for yet another audio format, para_write improvements and
303 bug fixes.
304
305 - Support for the speex codec.
306 - Support for sample formats other than 16 bit little endian.
307 - error2.h is now created by a perl script which speeds up configure
308 considerably.
309 - Fix a bug in the aac decoder which could lead to segfaults in
310 para_filter/para_audiod.
311 - Fixes for autoconf-2.66.
312
313 ----------------------------------------
314 0.4.3 (2010-07-05) "imaginary radiation"
315 ----------------------------------------
316
317 Many improvements for the DCCP and the UDP transport, the new user
318 manual and the usual mix of bug fixes and internal improvements.
319
320 - FEC support for the DCCP sender (Gerrit Renker). The new
321 --dccp_max_slice_size, --dccp_data_slices_per_group and
322 --dccp_slices_per_group options can be used to set the FEC
323 parameters for the DCCP transport.
324 - DNS lookups for UDP targets (Gerrit Renker).
325 - The new user manual replaces the README, README.afs, REQUIREMENTS
326 and INSTALL documents.
327 - Fix an end-of-file detection bug in the oggdec filter.
328 - The new nonblock API.
329 - Both options of the oggdec filter have been removed.
330 - New debug mode for the internal scheduler.
331
332 ------------------------------------------
333 0.4.2 (2010-04-23) "associative expansion"
334 ------------------------------------------
335
336 It's been some time since the last release, but finally here is
337 paraslash-0.4.2. The bulk of the changes comes from the new buffer
338 tree API, but there are changes all over the tree. Mainly performance
339 and usability improvements, but also quite some bug fixes.
340
341 - The new buffer tree API.
342 - DCCP: Support for CCID negotiation (Gerrit Renker).
343 - UDP robustness fixes.
344 - The --bufsize option for mp3dec is gone as it no longer makes sense
345 for the new buffer tree API.
346 - Fix audible buffer underruns for wma streams.
347 - The alsa writer no longer prints meaningless underrun durations.
348 - audiod: Defaults work also for udp streams. If no filter is
349 given for an audio format that is received via upd, fecdec is
350 automatically added as the first filter (along with the decoder).
351
352 ---------------------------------------
353 0.4.1 (2009-12-22) "concurrent horizon"
354 ---------------------------------------
355
356 Support for another audio format, minor feature enhancements and lots of bug
357 fixes. All fixes that have been accumulated in the maint branch (in particular
358 those mentionened in the 0.3.6 release notes) appear in this release as well.
359
360 - wma support.
361 - new afh option: --human to activate human-readable output.
362 - new server/audiod option: --log-timing to print timing information.
363 - build system improvements.
364 - source code documentation updates.
365
366 -------------------------------------
367 0.3.6 (2009-12-07) "cubic continuity"
368 -------------------------------------
369
370 Quite a few bugs have been found and fixed since 0.3.5, so here's
371 another 0.3.x release. No new features.
372
373 - Always check return value of malloc().
374 - ogg vorbis/FEC: Do not write garbage after the audio file header.
375 - exit if root privileges could not be dropped.
376 - FEC: Fix computation of extra slices.
377 - oss: Fix check for empty input buffer.
378 - Avoid buffer underruns due to filter chain output buffer constraints.
379 - server: Fix assignment of afs_pid.
380 - Don't panic if the afs database contains unknown audio formats.
381 - http/dccp: Do not send the audio file header twice.
382 - FEC: Timing improvements.
383
384 ----------------------------------------------
385 0.4.0 (2009-11-10) "simultaneous independence"
386 ----------------------------------------------
387
388 Two significant changes which require the new version number: The
389 improved authentication dialog and the fact that the database code
390 has been moved to a library, libosl. To use the new version, you have
391 to generate new RSA keys, see INSTALL for details. A shell script is
392 provided for conversion of the 0.3 database to the new 0.4 format.
393
394 - stronger crypto for client authentication
395 - the database code has been moved to a library
396 - improved status item handling
397 - cleanup of the build system
398 - The "-V" option now also prints the git version
399 - the new parser-friendly listing mode for the ls and stat commands
400 - mandatory rc4 encryption
401 - major audio format handler cleanups
402 - (id3,...) tags are no longer stored as a combined string in the database
403 - new mood methods: artist_matches, title_matches, comment_matches,
404 album_matches, year_maches, year.
405
406 --------------------------------------------
407 0.3.5 (2009-09-21) "symplectic separability"
408 --------------------------------------------
409
410 Full client support for *BSD Unixes, complete re-write of the ogg
411 vorbis audio format handler, various improvements all over the place
412 and the usual mix of bugfixes. This release marks the end of the 0.3
413 series if no serious problems show up.
414
415 - the new oss writer (supported on *BSD and Linux)
416 - rewrite of the ogg vorbis audio format handler. It's
417 recommended to replace the chunk tables of existing ogg
418 vorbis files in the afs database by re-adding these files
419 with "add -f".
420 - support for netmask subsets (Gerrit Renker)
421 - the new prebuffer filter
422 - improved signal handling
423 - variable fec output buffer size
424 - improved FEC timing fixes audible buffer underruns in UDP mode
425 - --log_color actually works
426 - new ls option: -d (print dates as seconds after the epoch)
427 - update to gengetopt 2.22.2
428 - support for RSA keys of size > 512 bits
429 - new option "mixer_channel" for para_fade
430
431 -----------------------------------------
432 0.3.4 (2009-05-07) "elliptic inheritance"
433 -----------------------------------------
434
435 The new udp sender, forward error correction, colored logs and various
436 other improvements. As the udp sender does not depend on any special
437 libraries, it is built unconditionally.
438
439 - The udp sender replaces the ortp sender. The new code uses forward
440 error correction to protect against packet losses. Many thanks to
441 Gerrit Renker for providing ipv6 support.
442 - The default port for udp streaming now defaults to 8000, like
443 for the http and the dccp senders/receivers.
444 - Loglevels are now specified as symbolic names, e.g.
445 "--loglevel info".
446 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
447 - para_server/para_audiod: Color support for log messages.
448 - new options for mp3dec: --ignore-crc, --bufsize
449 - new audiod option: --config-file.
450 - gengetopt cleanups.
451 - Improved help/man pages: The documentation of para_audiod,
452 para_recv, para_filter and para_write now also contains
453 all options of the available receivers/filters/writers. The
454 man page of para_fade contains a description of the different
455 modes of operation.
456 - More source code documentation.
457 - vss timing fixes.
458
459 --------------------------------------------
460 0.3.3 (2008-12-01) "axiomatic perspectivity"
461 --------------------------------------------
462
463 Internal code cleanups, bug fixes, improved tag handling and the new
464 amplification filter.
465
466 - para_server uses the generic scheduling code.
467 - overhaul of the virtual streaming system.
468 - mp3: id3 version 2 support via libid3tag (optional)
469 - ogg: vorbis comment support.
470 - aac meta info support.
471 - mp3 audio format handler cleanups.
472 - new filter: "amp" to amplify the amplitude of the audio stream
473 - new status item/database entry: amplification. It is
474 used by the amp filter to pre-amplify the audio stream.
475 - fix a close-without-open bug in para_write.
476 - fix a bug in com_init() which was introduced in 0.3.2.
477 - better error diagnostics for para_client.
478
479 -----------------------------------------
480 0.3.2 (2008-04-11) "probabilistic parity"
481 -----------------------------------------
482
483 The new para_afh executable, scheduling and documentation improvements.
484
485 - new ls option: -lc (list chunk table)
486 - new executable: para_afh, the stand-alone audio file handler tool
487 - afs commands can send output more than SHMMAX (32MB on Linux). This
488 also reduces the memory usage of commands that produce large amounts
489 of output.
490 - major scheduler and audiod cleanups.
491 - more detailed and much nicer man pages.
492
493 ---------------------------------------
494 0.3.1 (2008-02-23) "liquid interaction"
495 ---------------------------------------
496
497 A mix of cleanups, bug fixes, improvements, and some new features. No
498 significant changes to the new database (osl) code, which is generally
499 a good sign.
500
501 - Share some similar/duplicate code between the http and the
502 dccp sender.
503 - Generic access control lists for paraslash senders.
504 - dccp sender: Access control lists, connection limiting and support
505 for the allow,deny,on,off,help sender commands.
506 - The default dccp port changed from 5001 to 8000 (suggested by
507 Gerrit Renker).
508 - para_server starts even if not all public keys could be loaded.
509 - Audiod performance improvements.
510 - fix a bug in the "off" command of the http sender.
511 - fix some fd and memory leaks.
512 - Update to gengetopt-2.22.
513
514 -------------------------------------
515 0.3.0 (2008-01-12) "solar saturation"
516 -------------------------------------
517
518 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
519
520
521 Usually one might expect lots of new features AND a big increase in size
522 for a major release like this.
523
524 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
525 ever. The decrease in size is mostly due to the removal of some
526 graphical tools (which were only quick hacks anyway). But also the
527 fact that the mysql code is gone cuts down the size a bit.
528
529 Being independent of mysql comes at a cost: The fact that paraslash
530 now contains its own database (the object storage layer, osl) increases
531 the (stripped) binary size of para_server by ~50K on i386.
532
533 - no more restrictions on unique basenames.
534 - independent of mysql: The new self-contained object
535 storage layer (osl) replaces the mysql database.
536 - New executable para_fsck: Check integrity of osl tables.
537 - Lyrics support.
538 - Reliable audio file move/rename detection.
539 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
540 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
541 Solaris (sparc64).
542 - the new osl-based audio file selector (afs) replaces the random,
543 the playlist and the mysql selector of paraslash-0.2.x.
544 - IPv6 support (thanks to Gerrit Renker).
545 - paraslash-0.2.x streams are now called "moods". Writing
546 0.3.x-mood definitions should be both easier and more
547 powerful than writing 0.2.x-stream definitions.
548 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
549 been removed. The world is a better place without them. However,
550 para_gui is still there.
551 - afs tracks audio file selection also in playlist mode.
552 - few easy-to-use afs commands replace the many not-so-easy-to-use
553 mysql commands (and are available also in playlist mode).
554 - Improved error subsystem.
555 - The earth-shaking new logo.
556
557 -----------------------------------------
558 0.2.17 (2007-11-20) "isotropic threshold"
559 -----------------------------------------
560
561 Mainly bugfixes and cleanups in this version which marks the end of
562 the 0.2.x series if no serious bugs show up after the release.
563
564 - mysql_selector: fix a locking bug.
565 - universal chunk queueing.
566 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
567 to Gerrit Renker).
568 - be more carful wrt. signed vs. unsigned argument passing.
569 - cleanup error.h and fix some references to invalid error
570 codes.
571 - update to gengetopt-2.21.
572 - update to ortp-0.13.1.
573 - autoconf: extend checks for headers, library functions and
574 compiler characteristics.
575 - Fix streaming of large mp3 files.
576 - Fix an off-by-one bug in playlist handling.
577
578 --------------------------------------
579 0.2.16 (2007-04-05) "neural discharge"
580 --------------------------------------
581
582 The main change in this release is the major audio format handler
583 cleanup which removes some similar/duplicate code and makes it easier
584 to implement plugins for other audio formats. Of course, the usual mix
585 of other improvements/changes/bugfixes also made it into the release.
586
587 - simplified audio format handlers (most of the handling functions
588 were moved one layer up to the virtual streaming system).
589 - para_server uses mmap to read audio files
590 - repositioning of mp3 streams is much faster, in particular for
591 jumping near the end of large mp3 files.
592 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
593 and AFS_WRITE.
594 - fix a bug in para_filter that caused decoding of aac files
595 to start only after a few seconds.
596 - fix osx_writer hangs
597 - simplified dccp code (thanks to Gerrit Renker)
598 - the compress filter works also on big endian systems (ppc)
599
600 -----------------------------------------
601 0.2.15 (2007-02-16) "inductive resonance"
602 -----------------------------------------
603
604 Minor improvements, more documentation and a bunch of bug fixes.
605
606 - para_server: The server.users file is only read once on server
607 startup rather than for each connection
608 - mp3dec: Fix decoding of corrupt mp3 files
609 - afs (audio file sender) is now called vss (virtual streaming
610 system). Consequently, the permission flags specified in
611 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
612 become VSS_READ and VSS_WRITE respectively.
613 - para_audiod/para_filter: Fix a bug that caused the last chunk
614 of audio data not being written under certain circumstances
615 - audiod: compute the difference of server time and local time
616 correctly
617 - para_server/para_audiod: Fix some memory leaks
618 - documentation improvements
619 - configure.ac: fix checks for para_krell
620 - new man pages
621
622 -------------------------------------------
623 0.2.14 (2006-10-15) "transient singularity"
624 -------------------------------------------
625
626 The only major enhancement of this version is the osx writer which completes
627 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
628 until now for reasons beyond the scope of this changelog entry.
629
630 - new output plugin for Mac Os: the osx writer
631 - rename configure command line options from --enable-xxx-headers to
632 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
633 - configure: new command line options: --with-mad-headers,
634 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
635 - some robustness fixes
636 - dymamic audio format recognition for audiod
637 - para_server: new command line option: --autoplay_delay
638 - para_audiod: new command line option: --clock_diff_count
639
640 ---------------------------------------
641 0.2.13 (2006-07-14) "sonic convolution"
642 ---------------------------------------
643
644 A bunch of new features and core changes.
645
646 - the new paraslash scheduler, short and sweet.
647 - Support for m4a/mp4 files via the new aac audio format
648 handler/filter (requires libfaad).
649 - each writer has its own command line parser, just like
650 para_recv and para_filter.
651 - para_client and para_audioc use the error subsystem
652 - writers are integrated in para_audiod (currently linux-only)
653 - para_client is integrated in para_audiod
654 - random/playlist selector: improved info strings
655 - new audiod commands: tasks, kill
656 - update to libortp-0.10.1
657 - para_fade: wake time defaults to 8 hours from now
658 - update to autoconf-2.60
659
660 ------------------------------------------
661 0.2.12 (2006-05-12) "oriented abstraction"
662 ------------------------------------------
663
664 Many user-visible changes in this release and lots of new
665 features:
666
667
668 - the new optional dccp sender/receiver. It uses the datagram
669 congestion control protocol. You'll need a fairly new kernel
670 for this.
671 - paraslash works on Mac OS X (thanks to Gerd Becker)
672 - para_play renamed to para_write
673 - modular output plugin design (writers) for para_write
674 - new file_writer output plugin for para_write
675 - compress filter speed improvements
676 - update to libortp-0.9.1
677 - update to gengetopt-2.17rc
678 - para_client no longer depends on libreadline (as the
679 code for the interactive mode was removed).
680 - gcc-2-95 is no longer a supported compiler. It may still
681 work, but it gets no more testing.
682 - the tarball no longer contains the screenshot images which
683 reduces its size quite a bit.
684 - configure: new command line options: --enable-mysql-headers
685 and --enable-mysql-libs
686
687 ------------------------------------
688 0.2.11 (2006-03-11) "atomic duality"
689 ------------------------------------
690
691 Here it is, the first paraslash release developed with git. There
692 are fairly many user-visible changes in this release. As two out of
693 the three "database tools" of paraslash don't use a database at all,
694 they are now called "audio file selectors" instead.
695
696
697 - the cdt command (change database tool) becomes chs (change
698 selector)
699 - no more colon separators: The syntax of some options of
700 para_audiod and para_filter have changed. Use --help for
701 more info (and some examples).
702 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
703 - switch from cvs to git (should've done that earlier)
704 - the new ipc subsystem
705 - new audio file selector: playlist
706 - para_server: the dopey selector is now called "random",
707 and is the default selector. Use the --selector option to
708 choose another selector at startup, or the chs command to
709 change the selector at runtime.
710 - X86_64 fixes (thanks to Steffen Klassert)
711 - para_play fixes
712
713 --------------------------------------
714 0.2.10 (2006-02-17) "cyclic attractor"
715 --------------------------------------
716
717 Huge documentation update, a scrollable window for para_gui, ortp
718 improvements, and of course many small fixes not mentioned here.
719 The diffstat below is rather misleading as most insertions are due
720 to the new source documentation.
721
722 - autoconf cleanup
723 - para_server also uses the new error subsystem
724 - lots of new documentation (UTSL)
725 - gui improvements:
726 - keysyms for cursor keys and for next/previous page keys
727 - scrollable output window
728 - new internal commands: scroll up/down, page up/down
729 - fix color of command output.
730 - ortp: the --chunk_time and --header flags are no longer needed
731 for para_recv/para_audiod as this information is now encoded in
732 each rtp packet sent by para_server.
733
734 -------------------------------------------
735 0.2.9 (2006-01-24) "progressive turbulence"
736 -------------------------------------------
737
738 Internal audiod receivers/filters, the new error subsystem and
739 a lot of small improvements.
740
741 - para_recv and para_filter are integrated into the para_audiod
742 binary, i.e. audiod no longer spawns a new process for
743 each receiver/filter. As para_recv and para_filter might be
744 useful as standalone programs, they still get built (linked
745 against the same object files that are also used for audiod).
746 - further ortp timing improvements should reduce the CPU usage
747 of the ortp receiver.
748 - improved audio grabbing. The 'grab' command of para_audiod
749 has its own set of command line options. Read the output of
750 "para_audioc help grab" for more info.
751 - oggdec: configurable input prebuffer size.
752 - the new error subsystem gives better error diagnostics
753 and reduces code size.
754
755 -----------------------------------------
756 0.2.8 (2006-01-02) "dynamic accumulation"
757 -----------------------------------------
758
759 The new modular filter design and the para_play-hangs bugfix.
760
761 - new executable: para_filter. It combines para_mp3dec,
762 para_oggdec and para_compress. It also adds a further filter
763 type, wav, that just inserts a wave header at the desired point
764 of the filter chain. All 'piping' is done in-memory (i.e. no
765 read/write operations are used).
766 - para_play: fix a stupid bug that caused it to hang under
767 certain circumstances.
768
769 -------------------------------------------
770 0.2.7 (2006-12-27) "transparent invariance"
771 -------------------------------------------
772
773 Not many user-visible changes but a fair amount of internal improvements.
774
775
776 - The http sender buffers data if it can not be sent
777 out immediately (because the socket is not writable). This
778 should prevent para_server from shutting down the connection
779 too early on a loaded network.
780 - para_play also prebuffers data if it is told to start at a
781 future time by the --start_time option.
782 - The return of para_recv: It combines para_ortp_recv and
783 para_http_recv. Use the --receiver option to switch between
784 the two. para_recv builds without libortp, but contains
785 only the http receiver in this case.
786 - update to ortp 0.8.1. As this ortp release contains incompatible
787 changes, para_recv-0.2.7 won't link against older ortp libs.
788 - improved ortp timings.
789 - use of gcc-extensions that #define away for non-gcc and
790 gcc < 3.0.
791
792 -------------------------------------------
793 0.2.6 (2005-10-29) "recursive compensation"
794 -------------------------------------------
795
796 Transparent session encryption (uses openssl's Alleged RC4 cipher),
797 the internal find command and several other improvements and cleanups.
798
799 - Encrypt the session if encryption is requested by the client
800 (default for para_client 0.2.6). This is backwards
801 compatible, so older clients can still connect to para_server
802 0.2.6. Use the new client option --plain to request an
803 uncrypted session (off by default, must be set to on in
804 order to connect to para_server 0.2.x with 0 <= x <= 5).
805 - para_server uses an internal function to locate audio files
806 rather than calling find(1). The server option
807 --mysql_audio_file_dir replaces --mysql_find_cmd.
808 - documentation update
809 - man pages
810 - header file cleanup
811 - para_client code cleanup
812 - para_gui: faster display of output of display commands
813
814 ------------------------------------------
815 0.2.5 (2005-10-13) "aggressive resolution"
816 ------------------------------------------
817
818 This release adds internal senders, i.e. no more external programs are
819 spawned for sending out the audio data. There are two different senders
820 available: The http sender and the ortp sender (former para_send which
821 is no longer needed).
822
823 The new sender code has a plugin-like design so it can be easily
824 extended should there be be any future need for supporting another
825 network streaming protocol. All senders are completely independent of
826 each other. In particular, the http and the ortp sender can operate
827 in parallel.
828
829 - new server command: sender to control senders at runtime.
830 Read the output of "para_server -h" and "para_client help
831 sender" for more information.
832 - para_recv renamed to para_ortp_recv
833 - new executable: para_http_recv, a simple command line
834 http receiver.
835 - major afs/mp3/ogg code simplifications due to internal
836 senders.
837 - ogg timing improvements
838 - fix several minor memory leaks (found by valgrind)
839 - empty stream definitions work again
840 - com_ne(): ignore errors on remove
841 - audiod: fix segfault on server restart
842
843 ---------------------------------------
844 0.2.4 (2005-09-21) "toxic anticipation"
845 ---------------------------------------
846
847 Several small improvements, fixes and the new grab command.
848
849 - audiod:
850 - new command: "grab" to grab the output of the stream reader
851 or any filters. Read the output of "para_audioc help grab"
852 for more information.
853 - fix memory leak
854 - code cleanup
855 - audioc: new command line option: --bufsize to specify a
856 buffer size different from the default size 8192.
857 - improved error diagnostics for para_play.
858 - new configure option: --enable-ssldir so search for openssl in
859 non-standard places
860 - sdl_gui: Make it look nice again for 1024x768
861 - server: report total size of memory allocated with sbrk by malloc,
862 new command line option: --announce_time
863
864 -----------------------------------------
865 0.2.3 (2005-09-01) "hydrophilic movement"
866 -----------------------------------------
867
868 Two new executables and major feature enhancements.
869
870 - audiod filters: It is now possible to specify arbitrary many
871 (including none) filters for each supported audio
872 format. This can be used e.g. for normalizing volume,
873 transforming or grabbing the audio stream, or for using
874 visualizers. Read the output of "para_audiod -h" for the
875 syntax of the new --filter_cmd option.
876 - new executable: para_play, a tiny alsa player. It
877 can play wave files or raw pcm (16 bit little endian)
878 from stdin.
879 - new executable: para_compress, a dynamic range compressor
880 intended to keep audio output at a consistent volume. Derived
881 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
882 - audiod: New option: --stream_delay. This can be used in
883 a local network to syncronize the audio output of all
884 clients that play the same stream.
885
886 ------------------------------------------
887 0.2.2 (2005-08-19) "tangential excitation"
888 ------------------------------------------
889
890 Mostly internal changes in this release, but also some new commands
891 for the mysql database tool.
892
893 - cleanup exec.c, fix para_exec bug
894 - compile time loglevel (log messages below the given level
895 won't be compiled in, which reduces the size of the
896 resulting binaries)
897 - new log macros that shorten the size of the source code.
898 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
899 to send only zeros. With this workaround, para_audioc works
900 again.
901 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
902 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
903 (new entry), "snp" (set numplayed). Read the manual for more
904 information.
905
906 ---------------------------------------
907 0.2.1 (2005-08-15) "surreal experience"
908 ---------------------------------------
909
910 Here comes paraslash-0.2.1. It contains a couple of new features and,
911 surprise, only minor bug fixes.
912
913 - kill noisy mp3 debug message
914 - cleanup of the build system
915 - para_server and para_client directly use the crypto routines
916 of the openssl library rather than invoking the openssl command
917 line utitlity
918 - server/audiod: new option --user to switch to the given user
919 when invoked as root. Read the output of "para_server -h" for
920 more information.
921 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
922 status. Default: "para_audioc stat"
923 - sdl_gui: new option --pic_cmd to be used to download the picture.
924 Default: "para_client pic"
925 - audiod: 5 slots ought to be enough for everybody
926 - audiod: new status item: Uptime, kill hup command
927
928 ------------------------------------------
929 0.2.0 (2005-08-06) "distributed diffusion"
930 ------------------------------------------
931
932 After several month of increased development activity, paraslash-0.2.0
933 has arrived. It contains many new features and is much more
934 self-contained than the old 0.1.x series. Enjoy!
935
936
937 - para_server: fix hang on song change and crash on sighup.
938 Speed up mysql queries. The DIR_LIKE macro is gone.
939 - new executables: para_audiod, the local audio daemon that
940 starts playback (uses SCM_CREDENTIALS socket magic) and
941 para_audioc, the corresponding client.
942 - new executables: para_mp3dec/para_oggdec, two really teensy
943 decoders. para_mp3dec is based on libmad, para_oggdec requires
944 libvorbisfile.
945 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
946 they are now called para_send and para_recv respectively.
947 - documentation updates
948 - para_gui is themable. For now there is the default theme that
949 looks as before and the simple theme: blue and easy.
950 - gui: audio streaming is now handled by audiod. Time display shows
951 playback time rather than streaming time
952 - slider: update to libzmw-0.2.0
953 - para_krell: fix crash on server shutdown
954 - switch from gzip to bzip2
955
956 ----------------------------------------
957 0.1.7 (2005-04-18) "melting penetration"
958 ----------------------------------------
959
960 The main change in this release is clearly the oggvorbis rewrite,
961 but there are also lots of smaller changes. If you intend to use both
962 the mp3 and the ogg plugin, it is recommended to use software mixing,
963 e.g. the dmix plugin which is provided by ALSA.
964
965 - new executables: para_ovsend and para_ovrecv for sending/receiving
966 oggvorbis files via rtp. Requires the open rtp library. Get it at
967 http://www.linphone.org/ortp/
968 - rewrite of the ogg_vorbis core code
969 - configure detects libzmw and, if detected, includes
970 para_slider to the list of binaries to be built by make
971 - server stream writers read from their associated fifo rather
972 than from stdin
973 - slider: two new sliders, lastplayed and numplayed
974 - fix nasty double free bug which caused random segfaults in case of
975 mp3 files with invalid header information
976 - gui: new command line option: --stream_timeout=seconds to
977 deactivate a slot if it is idle for that many seconds (default=`5')
978 - diffstats
979
980 ---------------------------------------
981 0.1.6 (2005-03-05) "asymptotic balance"
982 ---------------------------------------
983
984 Only little user-visible changes in this release. Mainly bugfixes and
985 core code cleanup. This is probably the most stable version ever if you
986 stick to mp3...
987
988 - fix several memory leaks
989 - rename default name of mysql database from "music" to "paraslash".
990 Use para_server's --mysql_database option if you do not want to
991 rename your old database.
992 - rework ogg vorbis code
993 - make update command work on mysql servers with LOCAL_INFILE
994 disabled
995 - gui: improved stream I/O (slots)
996 - simplified audio format API
997 - para_pob_ogg is gone
998
999 ------------------------------------
1000 0.1.5 (2004-12-31) "opaque eternity"
1001 ------------------------------------
1002
1003 Let's slide gently into the new year.
1004
1005 - new: para_slider (not built automatically, type "make
1006 para_slider" to build). A toy for those who always felt that
1007 creating stream definitions is difficult. See screenshots,
1008 README and FEATURES for more info.
1009 - improved signal handling. Fixes server segfault on SIGHUP
1010 for linux kernels newer than Aug 24 2004 and makes para_gui
1011 race-free.
1012 - reload database tool on SIGHUP
1013 - improved help message for sl
1014 - do not log "broken pipe" messages as errors. They are
1015 perfectly ok.
1016 - fix wrong error message on permission errors
1017
1018 -----------------------------------------
1019 0.1.4 (2004-12-19) "tunneling transition"
1020 -----------------------------------------
1021
1022 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1023 Hopefully, most of them got wiped out with this release. Some
1024 enhancements went also in.
1025
1026 - improved error diagnostics for all commands
1027 - stradd/picadd: overwrite previous contents if entry already
1028 exists, rather than returning errors
1029 - stradd: use current stream if invoked without args
1030 - faster (and hopefully more stable) ogg-vorbis handling
1031 - para_krell: reap children to avoid zombie-flooding in case
1032 no server is running
1033 - si: report also server pid
1034 - server: don't busy-loop if dbtool reports only invalid files.
1035 - gui: CTRL+C works again, fix stream_read command line option
1036 - fix pic_add, hist
1037 - fix mysql dbtool startup in case no database exists
1038 - many small fixes and cleanups
1039
1040 ---------------------------------------
1041 0.1.3: (2004-12-10) "vanishing inertia"
1042 ---------------------------------------
1043
1044 Starting from this release, the database tools are integrated in the
1045 server binary. This decreases server startup time, reduces code size
1046 and speeds up database commands. However, the layout of the underlying
1047 mysql database changed only slightly and 0.1.3 should be backwards
1048 compatible in that respect.
1049
1050 Visible changes:
1051
1052 - If mysql is not detected at compile time, or fails to init
1053 at runtime, fall back to the dopey database tool which should
1054 always work.
1055 - para_dbtool and dbtool.conf are gone. All mysql specific
1056 options are read from server.conf and are prefixed by 'mysql_'.
1057 - new command: cdt (change database tool)
1058 - new command line option: dbtool (choose startup database tool)
1059 - The name of current stream is now stored in the database,
1060 so paraslash remembers its current stream when restarted.
1061 - new command: csp (change stream and play)
1062 - para_gui also reports current database tool and server uptime

1102 streaming software
1103 - new dbtool commands (stradd, strq, strdel) for easy stream
1104 managment w/o configuration file. That obsoletes stream_defs
