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

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

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

96 0.4.13 (2013-07-29) "spectral gravity"
97 --------------------------------------
98
99 One more 0.4.x release before the API-breaking changes for 0.5.0 go
100 in. The main features of this release are the ogg/opus audio format,
101 and UTF-8 support, but it includes also tons of other improvements
102 and fixes all over the place.
103
104 - New audio format: ogg/opus.
105 - UTF8 support for para_gui and the mp3 audio format handler.
106 - Scheduler improvements and fixes.
107 - The obsolete gettimeofday() function has been replaced
108 by clock_gettime() on systems which support it.
109 - Speed and usability improvements for para_gui.
110 - para_client now restores the fd flags of stdin and stdout
111 on shutdown.
112 - Improved manual pages.
113 - Consistent version strings for all executables.
114 - Reduced dependencies on generated files result in fewer
115 recompilations on changes.
116 - Performance improvements for the compress filter.
117 - Improved downloads web page.
118
119 -----------------------------------------
120 0.4.12 (2012-12-20) "volatile relativity"
121 -----------------------------------------
122 The new command line player, the resample filter, ALSA support for
123 para_fade, and the improved build system are the highlights of this
124 release which probably marks the end of the 0.4.x series.
125
126 - The afh receiver and the para_play executable.
127 - The resample filter: A sample rate converter based on
128 libsamplerate.
129 - The "versions" directory has been removed from the master
130 branch. The tarballs of the old releases are now available
131 in the new "releases" branch.
132 - Overhaul of the build system: All generated files are now
133 written to the "build" directory.
134 - The modular mixer API and the alsa mixer.
135 - Minor fixes for the osx writer.
136
137 --------------------------------------
138 0.4.11 (2012-07-20) "mutual diversity"
139 --------------------------------------
140
141 The major feature in this release is the new sideband API for
142 client-server communication. This API will be used exclusively starting
143 with 0.5.0, which breaks backward compatibility but allows to get rid
144 of quite some compatibility code. Other noteworthy changes include
145 decoder latency improvements and a long-standing bug fix for the
146 ALSA writer.
147
148 - Sideband connections: If both para_server and para_client
149 support this feature, data is sent as a multiplexed stream.
150 - The --no_default_filters option of para_filter has been
151 removed.
152 - Several fixes and latency improvements to various decoders.
153 - The ALSA writer now limits the prebuffer time to 500ms.
154 - Documentation improvements.
155 - Overhaul of the command_util.sh script.
156 - Fixes for some minor problems found by the clang analyzer.
157 - Compiles (almost) without warnings on gcc-3.
158 - Robustness improvements of the buffer tree code.
159
160 ------------------------------------------
161 0.4.10 (2012-03-30) "heterogeneous vacuum"
162 ------------------------------------------
163
164 Nothing earth-shaking in this release, but quite a few usability
165 improvements and the usual mix of cleanups and fixes.
166
167 - The --no_default_filters option of para_filter has been
168 deprecated. It still works but has no effect and will be
169 removed in the next version.
170 - para_gui now prints also the stderr output of the executing
171 command in the bottom window.
172 - Cleanup and consolidation of the various wrappers for
173 write(), writev(), send() and friends.
174 - The obscure error messages on mmap() failures have been
175 replaced by meaningful messages. This affects mainly
176 para_afh.
177 - para_audioc: Cleanups and memory leak fixes.
178 - Test 0004-server no longer fails if para_server is not
179 being built.
180 - New configure options: --with-id3tag-{headers,libs}.
181
182 -------------------------------------
183 0.4.9 (2011-12-06) "hybrid causality"
184 -------------------------------------
185
186 Support for another audio format, interactive mode for para_client
187 and para_audiod and many small improvements/fixes all over the place.
188
189 - Support for flac, the free lossless audio codec.
190 - Fix for an endless loop in the mp3 decoder for certain
191 (corrupt) mp3 files.
192 - When executed without specifying a command, para_client
193 and para_audioc start an interactive shell (requires
194 libreadline being installed). The interactive mode offers
195 full tab completion and command line history.
196 - autogen.sh now detects a distcc setup and adjusts the
197 parameter for the -j option of make accordingly.
198 - Shared memory areas are no longer restricted to 64K. We now
199 detect the maximal size of a shared memory area at runtime.
200 - cleanup of the internal uptime API.
201 - para_server prefaults the mmapped audio file to avoid
202 delays on slow media.
203 - A new test for the test-suite that exercises the
204 communication between para_server and para_audiod.
205 - The alsa writer eats up less CPU cycles when configured to
206 use the DMIX plugin.
207 - Simplified and unified receiver code.
208 - Makefile cleanups.
209 - Commands which print a list of matching audio files now
210 emit a meaningful error message if no audio file matched the
211 given pattern(s).
212
213 --------------------------------------
214 0.4.8 (2011-08-19) "nested assignment"
215 --------------------------------------
216
217 Gcrypt support, the overhauled osx writer and regex format specifiers
218 are the highlights of this release.
219
220 - support for libgcrypt as a drop-in replacement for openssl.
221 Run configure --enable-cryptolib=gcrypt to link against
222 libgcrypt. The two crypto implementations are compatible to
223 each other, i.e. a para_client executable linked against
224 gcrypt can connect to para_server linked against libssl
225 and vice versa.
226 - Rewrite of the osx writer (output plugin for Mac OS).
227 - audiod: The format specifier for receivers, filters and
228 writers is now treated as a regular expression. This allows
229 to replace 5 lines in the config file (one for each audio
230 format) by one single line. See the manual for details.
231 - The *.cmdline.[ch] files are no longer contained in the released
232 tarballs. This reduces the size of the tarballs but requires
233 gengetopt to build the tarball.
234 - Compiles cleanly also with llvm/clang.
235 - Corrupt mp3 files are handled more gracefully.
236 - The alsa writer uses poll fds instead of computing timeouts.
237 - Cleanup of the generic writer API.
238 - sched: Optimized zero timeouts.
239 - vss timeout cleanups.
240 - oggdec fixes and improvements.
241
242 --------------------------------------
243 0.4.7 (2011-06-01) "infinite rollback"
244 --------------------------------------
245
246 The new ao writer, support for ssh RSA keys and a couple of other
247 enhancements.
248
249 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
250 platforms through the libao audio library.
251 - Support for RSA keys generated with ssh-keygen.
252 - configure: improved options for ogg/vorbis/speex.
253 - The git version reported by --version always matches HEAD.
254 - The autogen script detects the number of processors and
255 runs a parallel make if possible.
256 - Major cleanup of the crypto API.
257 - Documentation updates.
258
259 ------------------------------------------
260 0.4.6 (2011-03-31) "deterministic entropy"
261 ------------------------------------------
262
263 Lots of ogg/vorbis improvements, the new test suite, enhancements
264 for para_gui and a fair amount of other bug fixes.
265
266 - For DCCP/OGG streams the audio file header is only sent once
267 at the beginning of the stream rather than periodically
268 every five seconds. This reduces network traffic and the
269 FEC group size.
270 - The vorbis comment header is replaced by an empty dummy header
271 before the header is sent over the network. This also results in
272 less network traffic and smaller FEC groups.
273 - The new "test" make target allows to perform some sanity checks prior
274 to installing the package.
275 - ogg timing fixes and performance improvements
276 - Scheduler improvements
277 - Proper exit codes for para_write
278 - para_gui: New option --theme to select a startup theme. Several
279 other improvements and fixes.
280 - aacdec error message cleanups
281 - simplified color error handling
282
283 --------------------------------------------
284 0.4.5 (2010-12-17) "symmetric randomization"
285 --------------------------------------------
286
287 Bug fixes, internal cleanups and variable-sized FEC slices.
288
289 - Contains a fix for an invalid-free-bug in the ogg audio format
290 handler code.
291 - Switching off the DCCP sender works again.
292 - para_audiod handles crashes of para_server more robustly.
293 - Internal scheduler and writer cleanups.
294 - Reduced latency due to variable-sized FEC slices.
295 - Improved documentation and error diagnostics.
296 - The build of para_server is now optional, allowing the build
297 to succeed in case libosl is not installed.
298
299 ------------------------------------------
300 0.4.4 (2010-08-06) "persistent regularity"
301 ------------------------------------------
302
303 Support for yet another audio format, para_write improvements and
304 bug fixes.
305
306 - Support for the speex codec.
307 - Support for sample formats other than 16 bit little endian.
308 - error2.h is now created by a perl script which speeds up configure
309 considerably.
310 - Fix a bug in the aac decoder which could lead to segfaults in
311 para_filter/para_audiod.
312 - Fixes for autoconf-2.66.
313
314 ----------------------------------------
315 0.4.3 (2010-07-05) "imaginary radiation"
316 ----------------------------------------
317
318 Many improvements for the DCCP and the UDP transport, the new user
319 manual and the usual mix of bug fixes and internal improvements.
320
321 - FEC support for the DCCP sender (Gerrit Renker). The new
322 --dccp_max_slice_size, --dccp_data_slices_per_group and
323 --dccp_slices_per_group options can be used to set the FEC
324 parameters for the DCCP transport.
325 - DNS lookups for UDP targets (Gerrit Renker).
326 - The new user manual replaces the README, README.afs, REQUIREMENTS
327 and INSTALL documents.
328 - Fix an end-of-file detection bug in the oggdec filter.
329 - The new nonblock API.
330 - Both options of the oggdec filter have been removed.
331 - New debug mode for the internal scheduler.
332
333 ------------------------------------------
334 0.4.2 (2010-04-23) "associative expansion"
335 ------------------------------------------
336
337 It's been some time since the last release, but finally here is
338 paraslash-0.4.2. The bulk of the changes comes from the new buffer
339 tree API, but there are changes all over the tree. Mainly performance
340 and usability improvements, but also quite some bug fixes.
341
342 - The new buffer tree API.
343 - DCCP: Support for CCID negotiation (Gerrit Renker).
344 - UDP robustness fixes.
345 - The --bufsize option for mp3dec is gone as it no longer makes sense
346 for the new buffer tree API.
347 - Fix audible buffer underruns for wma streams.
348 - The alsa writer no longer prints meaningless underrun durations.
349 - audiod: Defaults work also for udp streams. If no filter is
350 given for an audio format that is received via upd, fecdec is
351 automatically added as the first filter (along with the decoder).
352
353 ---------------------------------------
354 0.4.1 (2009-12-22) "concurrent horizon"
355 ---------------------------------------
356
357 Support for another audio format, minor feature enhancements and lots of bug
358 fixes. All fixes that have been accumulated in the maint branch (in particular
359 those mentionened in the 0.3.6 release notes) appear in this release as well.
360
361 - wma support.
362 - new afh option: --human to activate human-readable output.
363 - new server/audiod option: --log-timing to print timing information.
364 - build system improvements.
365 - source code documentation updates.
366
367 -------------------------------------
368 0.3.6 (2009-12-07) "cubic continuity"
369 -------------------------------------
370
371 Quite a few bugs have been found and fixed since 0.3.5, so here's
372 another 0.3.x release. No new features.
373
374 - Always check return value of malloc().
375 - ogg vorbis/FEC: Do not write garbage after the audio file header.
376 - exit if root privileges could not be dropped.
377 - FEC: Fix computation of extra slices.
378 - oss: Fix check for empty input buffer.
379 - Avoid buffer underruns due to filter chain output buffer constraints.
380 - server: Fix assignment of afs_pid.
381 - Don't panic if the afs database contains unknown audio formats.
382 - http/dccp: Do not send the audio file header twice.
383 - FEC: Timing improvements.
384
385 ----------------------------------------------
386 0.4.0 (2009-11-10) "simultaneous independence"
387 ----------------------------------------------
388
389 Two significant changes which require the new version number: The
390 improved authentication dialog and the fact that the database code
391 has been moved to a library, libosl. To use the new version, you have
392 to generate new RSA keys, see INSTALL for details. A shell script is
393 provided for conversion of the 0.3 database to the new 0.4 format.
394
395 - stronger crypto for client authentication
396 - the database code has been moved to a library
397 - improved status item handling
398 - cleanup of the build system
399 - The "-V" option now also prints the git version
400 - the new parser-friendly listing mode for the ls and stat commands
401 - mandatory rc4 encryption
402 - major audio format handler cleanups
403 - (id3,...) tags are no longer stored as a combined string in the database
404 - new mood methods: artist_matches, title_matches, comment_matches,
405 album_matches, year_maches, year.
406
407 --------------------------------------------
408 0.3.5 (2009-09-21) "symplectic separability"
409 --------------------------------------------
410
411 Full client support for *BSD Unixes, complete re-write of the ogg
412 vorbis audio format handler, various improvements all over the place
413 and the usual mix of bugfixes. This release marks the end of the 0.3
414 series if no serious problems show up.
415
416 - the new oss writer (supported on *BSD and Linux)
417 - rewrite of the ogg vorbis audio format handler. It's
418 recommended to replace the chunk tables of existing ogg
419 vorbis files in the afs database by re-adding these files
420 with "add -f".
421 - support for netmask subsets (Gerrit Renker)
422 - the new prebuffer filter
423 - improved signal handling
424 - variable fec output buffer size
425 - improved FEC timing fixes audible buffer underruns in UDP mode
426 - --log_color actually works
427 - new ls option: -d (print dates as seconds after the epoch)
428 - update to gengetopt 2.22.2
429 - support for RSA keys of size > 512 bits
430 - new option "mixer_channel" for para_fade
431
432 -----------------------------------------
433 0.3.4 (2009-05-07) "elliptic inheritance"
434 -----------------------------------------
435
436 The new udp sender, forward error correction, colored logs and various
437 other improvements. As the udp sender does not depend on any special
438 libraries, it is built unconditionally.
439
440 - The udp sender replaces the ortp sender. The new code uses forward
441 error correction to protect against packet losses. Many thanks to
442 Gerrit Renker for providing ipv6 support.
443 - The default port for udp streaming now defaults to 8000, like
444 for the http and the dccp senders/receivers.
445 - Loglevels are now specified as symbolic names, e.g.
446 "--loglevel info".
447 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
448 - para_server/para_audiod: Color support for log messages.
449 - new options for mp3dec: --ignore-crc, --bufsize
450 - new audiod option: --config-file.
451 - gengetopt cleanups.
452 - Improved help/man pages: The documentation of para_audiod,
453 para_recv, para_filter and para_write now also contains
454 all options of the available receivers/filters/writers. The
455 man page of para_fade contains a description of the different
456 modes of operation.
457 - More source code documentation.
458 - vss timing fixes.
459
460 --------------------------------------------
461 0.3.3 (2008-12-01) "axiomatic perspectivity"
462 --------------------------------------------
463
464 Internal code cleanups, bug fixes, improved tag handling and the new
465 amplification filter.
466
467 - para_server uses the generic scheduling code.
468 - overhaul of the virtual streaming system.
469 - mp3: id3 version 2 support via libid3tag (optional)
470 - ogg: vorbis comment support.
471 - aac meta info support.
472 - mp3 audio format handler cleanups.
473 - new filter: "amp" to amplify the amplitude of the audio stream
474 - new status item/database entry: amplification. It is
475 used by the amp filter to pre-amplify the audio stream.
476 - fix a close-without-open bug in para_write.
477 - fix a bug in com_init() which was introduced in 0.3.2.
478 - better error diagnostics for para_client.
479
480 -----------------------------------------
481 0.3.2 (2008-04-11) "probabilistic parity"
482 -----------------------------------------
483
484 The new para_afh executable, scheduling and documentation improvements.
485
486 - new ls option: -lc (list chunk table)
487 - new executable: para_afh, the stand-alone audio file handler tool
488 - afs commands can send output more than SHMMAX (32MB on Linux). This
489 also reduces the memory usage of commands that produce large amounts
490 of output.
491 - major scheduler and audiod cleanups.
492 - more detailed and much nicer man pages.
493
494 ---------------------------------------
495 0.3.1 (2008-02-23) "liquid interaction"
496 ---------------------------------------
497
498 A mix of cleanups, bug fixes, improvements, and some new features. No
499 significant changes to the new database (osl) code, which is generally
500 a good sign.
501
502 - Share some similar/duplicate code between the http and the
503 dccp sender.
504 - Generic access control lists for paraslash senders.
505 - dccp sender: Access control lists, connection limiting and support
506 for the allow,deny,on,off,help sender commands.
507 - The default dccp port changed from 5001 to 8000 (suggested by
508 Gerrit Renker).
509 - para_server starts even if not all public keys could be loaded.
510 - Audiod performance improvements.
511 - fix a bug in the "off" command of the http sender.
512 - fix some fd and memory leaks.
513 - Update to gengetopt-2.22.
514
515 -------------------------------------
516 0.3.0 (2008-01-12) "solar saturation"
517 -------------------------------------
518
519 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
520
521
522 Usually one might expect lots of new features AND a big increase in size
523 for a major release like this.
524
525 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
526 ever. The decrease in size is mostly due to the removal of some
527 graphical tools (which were only quick hacks anyway). But also the
528 fact that the mysql code is gone cuts down the size a bit.
529
530 Being independent of mysql comes at a cost: The fact that paraslash
531 now contains its own database (the object storage layer, osl) increases
532 the (stripped) binary size of para_server by ~50K on i386.
533
534 - no more restrictions on unique basenames.
535 - independent of mysql: The new self-contained object
536 storage layer (osl) replaces the mysql database.
537 - New executable para_fsck: Check integrity of osl tables.
538 - Lyrics support.
539 - Reliable audio file move/rename detection.
540 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
541 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
542 Solaris (sparc64).
543 - the new osl-based audio file selector (afs) replaces the random,
544 the playlist and the mysql selector of paraslash-0.2.x.
545 - IPv6 support (thanks to Gerrit Renker).
546 - paraslash-0.2.x streams are now called "moods". Writing
547 0.3.x-mood definitions should be both easier and more
548 powerful than writing 0.2.x-stream definitions.
549 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
550 been removed. The world is a better place without them. However,
551 para_gui is still there.
552 - afs tracks audio file selection also in playlist mode.
553 - few easy-to-use afs commands replace the many not-so-easy-to-use
554 mysql commands (and are available also in playlist mode).
555 - Improved error subsystem.
556 - The earth-shaking new logo.
557
558 -----------------------------------------
559 0.2.17 (2007-11-20) "isotropic threshold"
560 -----------------------------------------
561
562 Mainly bugfixes and cleanups in this version which marks the end of
563 the 0.2.x series if no serious bugs show up after the release.
564
565 - mysql_selector: fix a locking bug.
566 - universal chunk queueing.
567 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
568 to Gerrit Renker).
569 - be more carful wrt. signed vs. unsigned argument passing.
570 - cleanup error.h and fix some references to invalid error
571 codes.
572 - update to gengetopt-2.21.
573 - update to ortp-0.13.1.
574 - autoconf: extend checks for headers, library functions and
575 compiler characteristics.
576 - Fix streaming of large mp3 files.
577 - Fix an off-by-one bug in playlist handling.
578
579 --------------------------------------
580 0.2.16 (2007-04-05) "neural discharge"
581 --------------------------------------
582
583 The main change in this release is the major audio format handler
584 cleanup which removes some similar/duplicate code and makes it easier
585 to implement plugins for other audio formats. Of course, the usual mix
586 of other improvements/changes/bugfixes also made it into the release.
587
588 - simplified audio format handlers (most of the handling functions
589 were moved one layer up to the virtual streaming system).
590 - para_server uses mmap to read audio files
591 - repositioning of mp3 streams is much faster, in particular for
592 jumping near the end of large mp3 files.
593 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
594 and AFS_WRITE.
595 - fix a bug in para_filter that caused decoding of aac files
596 to start only after a few seconds.
597 - fix osx_writer hangs
598 - simplified dccp code (thanks to Gerrit Renker)
599 - the compress filter works also on big endian systems (ppc)
600
601 -----------------------------------------
602 0.2.15 (2007-02-16) "inductive resonance"
603 -----------------------------------------
604
605 Minor improvements, more documentation and a bunch of bug fixes.
606
607 - para_server: The server.users file is only read once on server
608 startup rather than for each connection
609 - mp3dec: Fix decoding of corrupt mp3 files
610 - afs (audio file sender) is now called vss (virtual streaming
611 system). Consequently, the permission flags specified in
612 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
613 become VSS_READ and VSS_WRITE respectively.
614 - para_audiod/para_filter: Fix a bug that caused the last chunk
615 of audio data not being written under certain circumstances
616 - audiod: compute the difference of server time and local time
617 correctly
618 - para_server/para_audiod: Fix some memory leaks
619 - documentation improvements
620 - configure.ac: fix checks for para_krell
621 - new man pages
622
623 -------------------------------------------
624 0.2.14 (2006-10-15) "transient singularity"
625 -------------------------------------------
626
627 The only major enhancement of this version is the osx writer which completes
628 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
629 until now for reasons beyond the scope of this changelog entry.
630
631 - new output plugin for Mac Os: the osx writer
632 - rename configure command line options from --enable-xxx-headers to
633 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
634 - configure: new command line options: --with-mad-headers,
635 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
636 - some robustness fixes
637 - dymamic audio format recognition for audiod
638 - para_server: new command line option: --autoplay_delay
639 - para_audiod: new command line option: --clock_diff_count
640
641 ---------------------------------------
642 0.2.13 (2006-07-14) "sonic convolution"
643 ---------------------------------------
644
645 A bunch of new features and core changes.
646
647 - the new paraslash scheduler, short and sweet.
648 - Support for m4a/mp4 files via the new aac audio format
649 handler/filter (requires libfaad).
650 - each writer has its own command line parser, just like
651 para_recv and para_filter.
652 - para_client and para_audioc use the error subsystem
653 - writers are integrated in para_audiod (currently linux-only)
654 - para_client is integrated in para_audiod
655 - random/playlist selector: improved info strings
656 - new audiod commands: tasks, kill
657 - update to libortp-0.10.1
658 - para_fade: wake time defaults to 8 hours from now
659 - update to autoconf-2.60
660
661 ------------------------------------------
662 0.2.12 (2006-05-12) "oriented abstraction"
663 ------------------------------------------
664
665 Many user-visible changes in this release and lots of new
666 features:
667
668
669 - the new optional dccp sender/receiver. It uses the datagram
670 congestion control protocol. You'll need a fairly new kernel
671 for this.
672 - paraslash works on Mac OS X (thanks to Gerd Becker)
673 - para_play renamed to para_write
674 - modular output plugin design (writers) for para_write
675 - new file_writer output plugin for para_write
676 - compress filter speed improvements
677 - update to libortp-0.9.1
678 - update to gengetopt-2.17rc
679 - para_client no longer depends on libreadline (as the
680 code for the interactive mode was removed).
681 - gcc-2-95 is no longer a supported compiler. It may still
682 work, but it gets no more testing.
683 - the tarball no longer contains the screenshot images which
684 reduces its size quite a bit.
685 - configure: new command line options: --enable-mysql-headers
686 and --enable-mysql-libs
687
688 ------------------------------------
689 0.2.11 (2006-03-11) "atomic duality"
690 ------------------------------------
691
692 Here it is, the first paraslash release developed with git. There
693 are fairly many user-visible changes in this release. As two out of
694 the three "database tools" of paraslash don't use a database at all,
695 they are now called "audio file selectors" instead.
696
697
698 - the cdt command (change database tool) becomes chs (change
699 selector)
700 - no more colon separators: The syntax of some options of
701 para_audiod and para_filter have changed. Use --help for
702 more info (and some examples).
703 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
704 - switch from cvs to git (should've done that earlier)
705 - the new ipc subsystem
706 - new audio file selector: playlist
707 - para_server: the dopey selector is now called "random",
708 and is the default selector. Use the --selector option to
709 choose another selector at startup, or the chs command to
710 change the selector at runtime.
711 - X86_64 fixes (thanks to Steffen Klassert)
712 - para_play fixes
713
714 --------------------------------------
715 0.2.10 (2006-02-17) "cyclic attractor"
716 --------------------------------------
717
718 Huge documentation update, a scrollable window for para_gui, ortp
719 improvements, and of course many small fixes not mentioned here.
720 The diffstat below is rather misleading as most insertions are due
721 to the new source documentation.
722
723 - autoconf cleanup
724 - para_server also uses the new error subsystem
725 - lots of new documentation (UTSL)
726 - gui improvements:
727 - keysyms for cursor keys and for next/previous page keys
728 - scrollable output window
729 - new internal commands: scroll up/down, page up/down
730 - fix color of command output.
731 - ortp: the --chunk_time and --header flags are no longer needed
732 for para_recv/para_audiod as this information is now encoded in
733 each rtp packet sent by para_server.
734
735 -------------------------------------------
736 0.2.9 (2006-01-24) "progressive turbulence"
737 -------------------------------------------
738
739 Internal audiod receivers/filters, the new error subsystem and
740 a lot of small improvements.
741
742 - para_recv and para_filter are integrated into the para_audiod
743 binary, i.e. audiod no longer spawns a new process for
744 each receiver/filter. As para_recv and para_filter might be
745 useful as standalone programs, they still get built (linked
746 against the same object files that are also used for audiod).
747 - further ortp timing improvements should reduce the CPU usage
748 of the ortp receiver.
749 - improved audio grabbing. The 'grab' command of para_audiod
750 has its own set of command line options. Read the output of
751 "para_audioc help grab" for more info.
752 - oggdec: configurable input prebuffer size.
753 - the new error subsystem gives better error diagnostics
754 and reduces code size.
755
756 -----------------------------------------
757 0.2.8 (2006-01-02) "dynamic accumulation"
758 -----------------------------------------
759
760 The new modular filter design and the para_play-hangs bugfix.
761
762 - new executable: para_filter. It combines para_mp3dec,
763 para_oggdec and para_compress. It also adds a further filter
764 type, wav, that just inserts a wave header at the desired point
765 of the filter chain. All 'piping' is done in-memory (i.e. no
766 read/write operations are used).
767 - para_play: fix a stupid bug that caused it to hang under
768 certain circumstances.
769
770 -------------------------------------------
771 0.2.7 (2006-12-27) "transparent invariance"
772 -------------------------------------------
773
774 Not many user-visible changes but a fair amount of internal improvements.
775
776
777 - The http sender buffers data if it can not be sent
778 out immediately (because the socket is not writable). This
779 should prevent para_server from shutting down the connection
780 too early on a loaded network.
781 - para_play also prebuffers data if it is told to start at a
782 future time by the --start_time option.
783 - The return of para_recv: It combines para_ortp_recv and
784 para_http_recv. Use the --receiver option to switch between
785 the two. para_recv builds without libortp, but contains
786 only the http receiver in this case.
787 - update to ortp 0.8.1. As this ortp release contains incompatible
788 changes, para_recv-0.2.7 won't link against older ortp libs.
789 - improved ortp timings.
790 - use of gcc-extensions that #define away for non-gcc and
791 gcc < 3.0.
792
793 -------------------------------------------
794 0.2.6 (2005-10-29) "recursive compensation"
795 -------------------------------------------
796
797 Transparent session encryption (uses openssl's Alleged RC4 cipher),
798 the internal find command and several other improvements and cleanups.
799
800 - Encrypt the session if encryption is requested by the client
801 (default for para_client 0.2.6). This is backwards
802 compatible, so older clients can still connect to para_server
803 0.2.6. Use the new client option --plain to request an
804 uncrypted session (off by default, must be set to on in
805 order to connect to para_server 0.2.x with 0 <= x <= 5).
806 - para_server uses an internal function to locate audio files
807 rather than calling find(1). The server option
808 --mysql_audio_file_dir replaces --mysql_find_cmd.
809 - documentation update
810 - man pages
811 - header file cleanup
812 - para_client code cleanup
813 - para_gui: faster display of output of display commands
814
815 ------------------------------------------
816 0.2.5 (2005-10-13) "aggressive resolution"
817 ------------------------------------------
818
819 This release adds internal senders, i.e. no more external programs are
820 spawned for sending out the audio data. There are two different senders
821 available: The http sender and the ortp sender (former para_send which
822 is no longer needed).
823
824 The new sender code has a plugin-like design so it can be easily
825 extended should there be be any future need for supporting another
826 network streaming protocol. All senders are completely independent of
827 each other. In particular, the http and the ortp sender can operate
828 in parallel.
829
830 - new server command: sender to control senders at runtime.
831 Read the output of "para_server -h" and "para_client help
832 sender" for more information.
833 - para_recv renamed to para_ortp_recv
834 - new executable: para_http_recv, a simple command line
835 http receiver.
836 - major afs/mp3/ogg code simplifications due to internal
837 senders.
838 - ogg timing improvements
839 - fix several minor memory leaks (found by valgrind)
840 - empty stream definitions work again
841 - com_ne(): ignore errors on remove
842 - audiod: fix segfault on server restart
843
844 ---------------------------------------
845 0.2.4 (2005-09-21) "toxic anticipation"
846 ---------------------------------------
847
848 Several small improvements, fixes and the new grab command.
849
850 - audiod:
851 - new command: "grab" to grab the output of the stream reader
852 or any filters. Read the output of "para_audioc help grab"
853 for more information.
854 - fix memory leak
855 - code cleanup
856 - audioc: new command line option: --bufsize to specify a
857 buffer size different from the default size 8192.
858 - improved error diagnostics for para_play.
859 - new configure option: --enable-ssldir so search for openssl in
860 non-standard places
861 - sdl_gui: Make it look nice again for 1024x768
862 - server: report total size of memory allocated with sbrk by malloc,
863 new command line option: --announce_time
864
865 -----------------------------------------
866 0.2.3 (2005-09-01) "hydrophilic movement"
867 -----------------------------------------
868
869 Two new executables and major feature enhancements.
870
871 - audiod filters: It is now possible to specify arbitrary many
872 (including none) filters for each supported audio
873 format. This can be used e.g. for normalizing volume,
874 transforming or grabbing the audio stream, or for using
875 visualizers. Read the output of "para_audiod -h" for the
876 syntax of the new --filter_cmd option.
877 - new executable: para_play, a tiny alsa player. It
878 can play wave files or raw pcm (16 bit little endian)
879 from stdin.
880 - new executable: para_compress, a dynamic range compressor
881 intended to keep audio output at a consistent volume. Derived
882 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
883 - audiod: New option: --stream_delay. This can be used in
884 a local network to syncronize the audio output of all
885 clients that play the same stream.
886
887 ------------------------------------------
888 0.2.2 (2005-08-19) "tangential excitation"
889 ------------------------------------------
890
891 Mostly internal changes in this release, but also some new commands
892 for the mysql database tool.
893
894 - cleanup exec.c, fix para_exec bug
895 - compile time loglevel (log messages below the given level
896 won't be compiled in, which reduces the size of the
897 resulting binaries)
898 - new log macros that shorten the size of the source code.
899 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
900 to send only zeros. With this workaround, para_audioc works
901 again.
902 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
903 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
904 (new entry), "snp" (set numplayed). Read the manual for more
905 information.
906
907 ---------------------------------------
908 0.2.1 (2005-08-15) "surreal experience"
909 ---------------------------------------
910
911 Here comes paraslash-0.2.1. It contains a couple of new features and,
912 surprise, only minor bug fixes.
913
914 - kill noisy mp3 debug message
915 - cleanup of the build system
916 - para_server and para_client directly use the crypto routines
917 of the openssl library rather than invoking the openssl command
918 line utitlity
919 - server/audiod: new option --user to switch to the given user
920 when invoked as root. Read the output of "para_server -h" for
921 more information.
922 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
923 status. Default: "para_audioc stat"
924 - sdl_gui: new option --pic_cmd to be used to download the picture.
925 Default: "para_client pic"
926 - audiod: 5 slots ought to be enough for everybody
927 - audiod: new status item: Uptime, kill hup command
928
929 ------------------------------------------
930 0.2.0 (2005-08-06) "distributed diffusion"
931 ------------------------------------------
932
933 After several month of increased development activity, paraslash-0.2.0
934 has arrived. It contains many new features and is much more
935 self-contained than the old 0.1.x series. Enjoy!
936
937
938 - para_server: fix hang on song change and crash on sighup.
939 Speed up mysql queries. The DIR_LIKE macro is gone.
940 - new executables: para_audiod, the local audio daemon that
941 starts playback (uses SCM_CREDENTIALS socket magic) and
942 para_audioc, the corresponding client.
943 - new executables: para_mp3dec/para_oggdec, two really teensy
944 decoders. para_mp3dec is based on libmad, para_oggdec requires
945 libvorbisfile.
946 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
947 they are now called para_send and para_recv respectively.
948 - documentation updates
949 - para_gui is themable. For now there is the default theme that
950 looks as before and the simple theme: blue and easy.
951 - gui: audio streaming is now handled by audiod. Time display shows
952 playback time rather than streaming time
953 - slider: update to libzmw-0.2.0
954 - para_krell: fix crash on server shutdown
955 - switch from gzip to bzip2
956
957 ----------------------------------------
958 0.1.7 (2005-04-18) "melting penetration"
959 ----------------------------------------
960
961 The main change in this release is clearly the oggvorbis rewrite,
962 but there are also lots of smaller changes. If you intend to use both
963 the mp3 and the ogg plugin, it is recommended to use software mixing,
964 e.g. the dmix plugin which is provided by ALSA.
965
966 - new executables: para_ovsend and para_ovrecv for sending/receiving
967 oggvorbis files via rtp. Requires the open rtp library. Get it at
968 http://www.linphone.org/ortp/
969 - rewrite of the ogg_vorbis core code
970 - configure detects libzmw and, if detected, includes
971 para_slider to the list of binaries to be built by make
972 - server stream writers read from their associated fifo rather
973 than from stdin
974 - slider: two new sliders, lastplayed and numplayed
975 - fix nasty double free bug which caused random segfaults in case of
976 mp3 files with invalid header information
977 - gui: new command line option: --stream_timeout=seconds to
978 deactivate a slot if it is idle for that many seconds (default=`5')
979 - diffstats
980
981 ---------------------------------------
982 0.1.6 (2005-03-05) "asymptotic balance"
983 ---------------------------------------
984
985 Only little user-visible changes in this release. Mainly bugfixes and
986 core code cleanup. This is probably the most stable version ever if you
987 stick to mp3...
988
989 - fix several memory leaks
990 - rename default name of mysql database from "music" to "paraslash".
991 Use para_server's --mysql_database option if you do not want to
992 rename your old database.
993 - rework ogg vorbis code
994 - make update command work on mysql servers with LOCAL_INFILE
995 disabled
996 - gui: improved stream I/O (slots)
997 - simplified audio format API
998 - para_pob_ogg is gone
999
1000 ------------------------------------
1001 0.1.5 (2004-12-31) "opaque eternity"
1002 ------------------------------------
1003
1004 Let's slide gently into the new year.
1005
1006 - new: para_slider (not built automatically, type "make
1007 para_slider" to build). A toy for those who always felt that
1008 creating stream definitions is difficult. See screenshots,
1009 README and FEATURES for more info.
1010 - improved signal handling. Fixes server segfault on SIGHUP
1011 for linux kernels newer than Aug 24 2004 and makes para_gui
1012 race-free.
1013 - reload database tool on SIGHUP
1014 - improved help message for sl
1015 - do not log "broken pipe" messages as errors. They are
1016 perfectly ok.
1017 - fix wrong error message on permission errors
1018
1019 -----------------------------------------
1020 0.1.4 (2004-12-19) "tunneling transition"
1021 -----------------------------------------
1022
1023 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1024 Hopefully, most of them got wiped out with this release. Some
1025 enhancements went also in.
1026
1027 - improved error diagnostics for all commands
1028 - stradd/picadd: overwrite previous contents if entry already
1029 exists, rather than returning errors
1030 - stradd: use current stream if invoked without args
1031 - faster (and hopefully more stable) ogg-vorbis handling
1032 - para_krell: reap children to avoid zombie-flooding in case
1033 no server is running
1034 - si: report also server pid
1035 - server: don't busy-loop if dbtool reports only invalid files.
1036 - gui: CTRL+C works again, fix stream_read command line option
1037 - fix pic_add, hist
1038 - fix mysql dbtool startup in case no database exists
1039 - many small fixes and cleanups
1040
1041 ---------------------------------------
1042 0.1.3: (2004-12-10) "vanishing inertia"
1043 ---------------------------------------
1044
1045 Starting from this release, the database tools are integrated in the
1046 server binary. This decreases server startup time, reduces code size
1047 and speeds up database commands. However, the layout of the underlying
1048 mysql database changed only slightly and 0.1.3 should be backwards
1049 compatible in that respect.
1050
1051 Visible changes:
1052
1053 - If mysql is not detected at compile time, or fails to init
1054 at runtime, fall back to the dopey database tool which should
1055 always work.
1056 - para_dbtool and dbtool.conf are gone. All mysql specific
1057 options are read from server.conf and are prefixed by 'mysql_'.
1058 - new command: cdt (change database tool)
1059 - new command line option: dbtool (choose startup database tool)
1060 - The name of current stream is now stored in the database,
1061 so paraslash remembers its current stream when restarted.
1062 - new command: csp (change stream and play)
1063 - para_gui also reports current database tool and server uptime

1103 streaming software
1104 - new dbtool commands (stradd, strq, strdel) for easy stream
1105 managment w/o configuration file. That obsoletes stream_defs
