11 0.7.0 (2022-03-12) "seismic orbit"
12 ----------------------------------
13
14 The major incompatible change which requires to bump the major version
15 is the switch from sha1 to sha256, see below for details. However,
16 there are many other improvements, the usual amount of bug fixes and
17 a couple of new features.
18
19 - Starting with paraslash-0.7.0, the sha256 hash value of each known
20 audio file is stored in the database while older versions employed the
21 sha1 hash algorithm which has been considered insecure since 2005
22 and should no longer be used today. The switch from sha1 to sha256
23 requires users to upgrade their database using the new para_upgrade_db
24 program, followed by re-adding all files to recompute the hashes. With
25 this approach all metadata stored in the database (last played date,
26 num played value, moods, playlists, attributes etc.) are kept. An
27 simpler alternative is to start over from scratch by running the
28 "init" command but this will lose these metadata.
29 - Server and client now hash the session keys with sha256 rather
30 than sha1 during the initial handshake. This feature is optional and
31 backwards compatible: old clients can still connect to a new server
32 (using sha1). Also new clients can connect to an old server (again
33 using sha1).
34 - The new "duration" keyword of the mood grammar makes it possible to
35 impose a constraint on the duration of the admissible files.
36 - The long deprecated version 1 mood syntax is no longer supported.
37 - Paraslash writers handle early end-of-file more gracefully.
38 - The alsa writer no longer warns about spurious underruns.
39 - The score formula of the audio file selector has been reworked.
40 - Cleanups of the doubly linked lists code.
41 - New option for configure: --enable-ubsan to detect and report undefined
42 behaviour.
43 - The "tasks" server command has been removed.
44 - The fancy new logo and a minor overhaul of the web pages.

51 0.6.4 (2021-11-04) "fuzzy calibration"
52 --------------------------------------
53
54 This point release contains a fair number of fixes but no new features.
55 This marks the end of the 0.6 development, although paraslash-0.6 will
56 still be supported for some time and subsequent maintenance releases
57 may follow.
58
59 - The udp sender no longer crashes when empty chunks are encountered.
60 - Fix a double-free bug in the exit path of the server.
61 - The "jmp" command now errors out when given a negative percentage.
62 - A fix for a bug in para_afh which triggered on the attempt to modify
63 the tags of an invalid mp4 file.
64 - A memory leak in para_afh has been fixed.
65 - The udp sender no longer sends multiple EOF packets.
66 - Some gcc warnings have been silenced.
67 - Minor log level adjustments and documentation improvements.

74 0.5.9 (2021-11-04) "reversed dimension"
75 ---------------------------------------
76
77 This release contains a few important fixes which have accumulated in
78 the maint branch. The paraslash-0.5.x series has now reached its end
79 of life and will no longer be supported. All users should upgrade to
80 a more recent version at this point.
81
82 - Fix an issue with the bash completion script.
83 - Initialize the random seed also when using libgrypt.
84 - Fix some compiler warnings in the resample filter
85 - Don't return spurious errors from the ff server command.

92 0.6.3 (2021-02-18) "generalized activity"
93 -----------------------------------------
94
95 It has been a while since the last release, but paraslash-0.6.3
96 finally has arrived. It contains a fair number of improvements,
97 features and fixes all over the place.
98
99 - The ff command now accepts a negative argument to instruct the
100 virtual streaming system to jump backwards in the current audio
101 stream. The old syntax (e.g., "ff 30-") is still supported but it
102 is deprecated and no longer documented. The compatibility code is
103 sheduled for removal after 0.7.0.
104 - para_afh: New option: --preserve to reset the modification time to
105 the value of the original file after meta data modification.
106 - Overhaul of the compress filter code. The refined algorithm should
107 reduce clipping. The meaning of --aggressiveness has changed, see the
108 updated and extended documentation of the compress filter for details.
109 - Cleanup of the audio format handler code.
110 - We now build the tree using the .ONESHELL feature of GNU make,
111 which results in a significant speedup.
112 - Two robustness fixes for FreeBSD.
113 - para_client now supports RFC4716 private keys as generated with
114 ssh-keygen -m RFC4716. In fact, this key format has been made the
115 default, and the former PEM keys will be depreciated at some point.
116 - The ogg audio format handlers learned to detect holes and now report
117 the correct duration also if ogg pages are missing in the file. This
118 affects ogg/vorbis ogg/speex and ogg/opus.
119 - Robustness improvements for para_mixer.
120 - A fix for an old bug that could cause the server to crash or report
121 garbage in its status output.
122 - New para_play option: --end-of-playlist
123 - Streaming m4a files over udp has been improved.

130 0.6.2 (2018-06-30) "elastic diversity"
131 --------------------------------------
132
133 The main new feature of this release is the --listen-address option
134 for para_server and para_audiod. But there are also a large number of
135 small improvements and bug fixes all over the place. The user-visible
136 changes include
137
138 - para_gui no longer waits up to one second to update the screen when
139 the geometry of the terminal changes.
140 - Minor documentation improvements.
141 - Improvements to the crypto subsystem.
142 - The server subcommand "task" has been deprecated. It still works,
143 but prints nothing. It will be removed in the next major release.
144 - Server log output is now serialized, avoiding issues with partial
145 lines.
146 - It is now possible to switch to a different afs database by changing
147 the server configuration and sending SIGHUP to the server process.
148 - New server options: --listen--address, --http-listen-address and
149 --dccp-listen-address. These options restrict the set of listening
150 addresses of the TCP and DCCP sockets of the server process.
151 - The help commands of server, audiod, play now support --long. By default,
152 the short help is shown.
153 - The code which merges the command line options with the config file
154 options has been consolidated.
155 - If the current audio file is renamed, the status items are now updated
156 accordingly.
157 - After the server process received SIGHUP, changes to the current audio
158 file did not trigger an update of the status items. This has been fixed.

165 0.6.1 (2017-09-23) "segmented iteration"
166 ----------------------------------------
167
168 The highlight of this release is the version 2 mood parser. But there
169 is a lot more than that, as summarized in the list below. And of
170 course we have many small usability improvements and bug fixes not
171 mentioned here.
172
173 - A more intuitive syntax for moods ("version 2 moods"). The
174 traditional version 1 moods are still supported but are deprecated
175 now. Removal of the version 1 mood parser is scheduled for the next
176 major release.
177 - Flex and bison are now required to build para_server.
178 - New sort order for the ls command: -s=h sorts the ls output by hash
179 value of the audio file.
180 - autogen.sh now runs the test suite after a successful build.
181 - The contents of overview.pdf have been integrated into the user
182 manual.
183 - Fixed sized audio format headers for ogg/opus streams.
184 - The doxygen source browser has been disabled temporarily. The
185 API reference is still online, though.
186 - Overhaul of the source code documentation.
187 - The deprecated --full-path option of the ls command has been
188 removed. It was a no-op since 0.6.0.
189 - The wma decoder has been cleaned up and its bitstream API made
190 more robust.
191 - The image/lyrics ID status items of the current audio file are now
192 updated on changes. This affects para_gui, which used to report the
193 old value until EOF.

202
203 A couple of fixes for serious old bugs have accummulated in the maint
204 branch since paraslash-0.5.7 was released nine months ago. So here
205 is another 0.5.x release. As usual, all commits in the maint branch
206 have been merged into master, so the upcoming paraslash-0.6.1 also
207 contains them. For details see the git log.

213 -------------------------------
214 0.6.0 (2017-04-28) "fuzzy flux"
215 -------------------------------
216
217 The highlights of this release are the conversion of all option parsers
218 to the lopsub library and the improved AAC support. But there are
219 many other user-visible changes all over the place. Also a lot of
220 old cruft has been removed, leading to incompatible changes. Hence
221 the new major version number.
222
223 - Support for Mac OS X has been removed.
224 - On Linux systems, glibc-2.17 or newer is required to build the
225 source tree.
226 - Support for RSA public keys in ASN format (as generated by openssl
227 genrsa) has been removed. These keys have been deprecated since
228 2011, so users should have long switched to keys generated with
229 ssh-keygen(1).
230 - If libgcrypt is used as the crypto library, we now require version
231 1.5.0 (released in 2011) or later.
232 - The insecure RC4 stream cipher has been removed. It was superseded
233 by aes_ctr128 three years ago but the RC4 code had been kept for
234 backwards compatibility.
235 - On Linux, abstract unix domain sockets are used unconditionally.
236 - The "install" target no longer strips executables, the new
237 install-strip target can be used to get the old behaviour.
238 - The clean targets have been renamed: clean2 is gone, and the new
239 mostlyclean removes only the executables and object files.
240 - New target: check (identical to test).
241 - The DESTDIR make variable is honored to prepend a path to the
242 installation directory. This feature is orthogonal to the --prefix
243 option to configure.
244 - Minor WMA cleanups.
245 - The aac audio format handler has been rewritten to use the mp4ff library.
246 See the manual for how to install the library on your system.
247 - New status item: max_chunk_size. The value is stored in a previously
248 unused field of the afhi object of the aft table. Although backwards
249 compatible, users are encouraged to re-add m4a files to populate
250 the new field.
251 - No more chunk tables for aac. Chunk boundaries are determined
252 dynamically at stream time.
253 - Release and master branch tarballs are now compressed with xz rather
254 than bzip2.
255 - The lopsub package is required to install the paraslash package.
256 Gengetopt is no longer needed.
257 - make dep is gone. Dependencies have been created automatically for
258 a long time and it was never necessary to run make dep manually.
259 - para_gui lost its --timeout option.
260 - Most manual pages have been extended to include an overall
261 description of the command.
262 - The --stream-delay option of para_audiod has been removed. It had
263 been a no-op for many years.
264 - The deprecated --path option of the server ls command has been
265 removed. The command now prints full paths by default, making
266 --full-path a no-op. Hence --full-path has been depreacted and is
267 scheduled for removal in v0.6.1.
268 - It is now possible to use 'CFLAGS' to override the default compiler
269 options.
270 - para_fade has been renamed to para_mixer. The four modes of operation
271 (set, fade, snooze, sleep) are implemented as subcommands of the
272 new program.
273 - The sleep subcommand of para_mixer (former sleep mode of para_fade)
274 lost its --wake-hour and --wake-min options in favor of the new
275 --wake-time option which also accepts relative wakeup times like
276 "+9:30".
277 - The new --fade-exponent option of para_mixer allows for non-linear
278 channel fading.
279 - The new logo.

289 Mostly a bug fix release, and a bunch of internal improvements.
290 The only user-visible changes are the sanity checks for the touch
291 command and the new options to the ls command.
292
293 - Speedup of the base64 decoder.
294 - One of the two source browsers has been removed from the web pages.
295 The doxygen API reference still contains an HTML version of each
296 source file.
297 - Two race conditions in para_server have been fixed.
298 - ls -p is now deprecated in favor of -F or -b. See the help text of
299 the ls command for details.
300 - The openssl code has been adjusted to work also with openssl-1.1.
301 - The wma decoder and audio format handler now correctly decodes
302 files with unusual block sizes.
303 - We now compile with -Wformat-signedness if possible.
304 - The touch command now refuses to set an invalid image or lyrics ID.
305 - New section on contributing for the user manual.
306 - Major simplification of the error subsystem.

313 0.4.14 (2016-12-31) "branching oscillation"
314 -------------------------------------------
315
316 Many fixes for nasty bugs have accumulated over the years since 0.4.13
317 was released in 2013. This release contains all of them. It is the
318 last v0.4.x release, so v0.4.x is now end of life. The maint branch
319 of the git repository has been forwarded to v0.5.7 and will start to
320 receive important fixes for 0.5.x, which is now in maintenance mode.
321
322 - Fix for the "double encryption bug" with gcrypt, which caused
323 garbage to be sent to stat clients.
324 - The "prev" command of para_play now works as expected.
325 - Invalid parameters for the begin and end chunk no longer cause
326 the afh receiver of para_recv to segfault.
327 - A fix for an assertion that triggered in the FEC slice setup code.
328 - Closing the terminal with a running para_gui causes the process to
329 die, rather than using 100% of CPU time.
330 - para_gui no longer shows stale information about the previous
331 audio file.
332 - A fix for a bug in the fec decoder which caused aborts if the buffer
333 pool filled up.
334 - The assertion in the buffer tree code no longer triggers.
335 - The "afs_event: table moods, event 0: key already exists in rbtree"
336 error no longer occurs on attribute changes.
337 - A NULL pointer dereference in com_sender() has been fixed.
338 - The -i option of lsatt works as advertised.
339 - Various fixes for the build system.

346 0.5.6 (2016-07-10) "cascading gradient"
347 ---------------------------------------
348
349 The highlight of this release is the new -m flag for para_afh which
350 lets it modify the meta tags of the given audio file(s). This feature
351 is supported for all audio formats. Many small cleanups and bug fixes
352 not mentioned here have accumulated and are also part of the release.
353
354 - para_afh learned to modify meta tags of mp3 wma ogg spx
355 opus flac aac files.
356 - afs commands propagate error codes to the client.
357 - The check command now also checks the attribute table for
358 inconsistencies.
359 - New -v flag for the version command (print verbose version string)
360 - New option --priority for para_server and para_audiod.
361 - New mood methods: image_id and lyrics_id.
362 - The manual and this NEWS file have been converted to markdown.
363 - Support for the compile-time loglevel feature has been removed.
364 - Cleanup of the wma decoder and bitstream code.
365 - Improved wide-character support and fixes related to signal handling.
366 - para_gui no longer reports 100% playing time at the stream start.
367 - Opus cleanups.

377 Many new features and a lot of other improvements.
378
379 - On Linux systems, local sockets are now created in the
380 abstract name space by default. This allows to get rid of
381 the socket specials in /var/paraslash.
382 - The --user-allow option of para_audiod now accepts also
383 usernames rather than only user IDs.
384 - New autoconf macros to avoid duplication in configure.ac.
385 - Status items (as shown by para_gui) are updated correctly
386 when the meta information of the current audio changes.
387 - para_server and para_audiod no longer refuse to start in
388 the background if no log file is given. Instead, all log
389 messages go to /dev/null in this case.
390 - Web page cleanup.
391 - New syntax for the -l and -s options of the ls command.
392 These options should now be specified as -l=v rather than
393 -lv, for example. The old syntax still works, but support
394 will be dropped in v0.6.0.

427 - para_gui has been converted to use the paraslash scheduler.
428 - Various alsa-related fixes, mostly for the raspberry pi.
429 - Many scheduler improvements and cleanups.
430 - The test suite has been extended to include sanity checks
431 for the generated man pages.
432 - ao_writer fixes. This writer was in a quite bad shape. Many
433 serious bugs have been fixed.
434 - new audiod command: version.
435 - Minor improvements to the bitstream API.
436 - The cpsi command now prints a meaningful error message if
437 none of the given patterns matched any audio file.

447 The new sync filter, the AES_CTR128 stream cipher and the overhauled
448 network code are the highlights of this release. It also includes a
449 fair number of smaller fixes and improvements not mentioned here.
450
451 - The new sync filter synchronizes playback between multiple
452 clients.
453 - Connections between para_server and para_client are now
454 encrypted by means of AES rather than RC4 if both sides
455 support it. RC4 is still available as a fallback. This
456 feature is fully transparent, i.e. no command line options
457 are necessary, and a client linked against openssl can
458 speak with a server linked against libgcrypt and vice versa.
459 - Major cleanup of the networking subsystem.
460 - Improvements to para_fade: the new set mode, multi-channel
461 initial volumes, better error logging.
462 - The man pages of para_audiod, para_filter, para_recv, and
463 para_write contain the relevant options for receivers, filters,
464 writers. This broke in 0.5.0.
465 - ogg/vorbis latency improvements.
466 - Improved user manual.
467 - Minor fixes to avoid clang warnings.

474 0.5.1 (2013-12-20) "temporary implication"

476
477 Lots of fixes and improvements all over the place, and a major overhaul
478 of the build system.
479
480 - Audiod improvements and fixes.
481 - Buffer tree robustness improvements.
482 - Cleanup of the mood subsystem.
483 - Fixes and cleanups for the flac decoder.
484 - Latency improvements for the ogg/opus decoder.
485 - Crypto support is now optional. On systems without
486 openssl/gcrypt, the build succeeds but para_server,
487 para_audiod, para_client won't be built.
488 - The build system now works for cross-compile setups.
489 - The dependency tree has been flattened, which speeds up
490 builds and avoids to recreate the man pages on every change.
491 - The error code helper has been rewritten from perl to C,
492 which further improves build time.
493 - Many small bugs in the build system have been identified
494 and fixed.

504 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
505
506 - The sideband compatibility code has been removed, hence
507 sideband connections (introduced in 0.4.11) are now mandatory.
508 - Addblob commands can produce output.
509 - The stat command no longer sends garbage when para_server was
510 compiled against libgcrypt.
511 - Dependencies for gengetopt files are computed automatically.
512 This eliminates a constant source of build bugs.
513 - The setatt command now accepts file name patterns rather than only
514 path names.
515 - overview.pdf is now based on dia, a simple diagram creation program.
516 The new version is much more detailed and contains descriptions of
517 the various programs of the paraslash package.
518 - The separator of all multi-word options has been changed from
519 underscore to dash. For example --log_color becomes --log-color.
520 - Overhauled web pages and the new logo.

525
526 --------------------------------------
527 0.4.13 (2013-07-29) "spectral gravity"
528 --------------------------------------
529
530 One more 0.4.x release before the API-breaking changes for 0.5.0 go
531 in. The main features of this release are the ogg/opus audio format,
532 and UTF-8 support, but it includes also tons of other improvements
533 and fixes all over the place.
534
535 - New audio format: ogg/opus.
536 - UTF8 support for para_gui and the mp3 audio format handler.
537 - Scheduler improvements and fixes.
538 - The obsolete gettimeofday() function has been replaced
539 by clock_gettime() on systems which support it.
540 - Speed and usability improvements for para_gui.
541 - para_client now restores the fd flags of stdin and stdout
542 on shutdown.
543 - Improved manual pages.
544 - Consistent version strings for all executables.
545 - Reduced dependencies on generated files result in fewer
546 recompilations on changes.
547 - Performance improvements for the compress filter.
548 - Improved downloads web page.
549
550 -----------------------------------------
551 0.4.12 (2012-12-20) "volatile relativity"
552 -----------------------------------------
553 The new command line player, the resample filter, ALSA support for
554 para_fade, and the improved build system are the highlights of this
555 release which probably marks the end of the 0.4.x series.
556
557 - The afh receiver and the para_play executable.
558 - The resample filter: A sample rate converter based on
559 libsamplerate.
560 - The "versions" directory has been removed from the master
561 branch. The tarballs of the old releases are now available
562 in the new "releases" branch.
563 - Overhaul of the build system: All generated files are now
564 written to the "build" directory.
565 - The modular mixer API and the alsa mixer.
566 - Minor fixes for the osx writer.
567
568 --------------------------------------
569 0.4.11 (2012-07-20) "mutual diversity"
570 --------------------------------------
571
572 The major feature in this release is the new sideband API for
573 client-server communication. This API will be used exclusively starting
574 with 0.5.0, which breaks backward compatibility but allows to get rid
575 of quite some compatibility code. Other noteworthy changes include
576 decoder latency improvements and a long-standing bug fix for the
577 ALSA writer.
578
579 - Sideband connections: If both para_server and para_client
580 support this feature, data is sent as a multiplexed stream.
581 - The --no_default_filters option of para_filter has been
582 removed.
583 - Several fixes and latency improvements to various decoders.
584 - The ALSA writer now limits the prebuffer time to 500ms.
585 - Documentation improvements.
586 - Overhaul of the command_util.sh script.
587 - Fixes for some minor problems found by the clang analyzer.
588 - Compiles (almost) without warnings on gcc-3.
589 - Robustness improvements of the buffer tree code.
590
591 ------------------------------------------
592 0.4.10 (2012-03-30) "heterogeneous vacuum"
593 ------------------------------------------
594
595 Nothing earth-shaking in this release, but quite a few usability
596 improvements and the usual mix of cleanups and fixes.
597
598 - The --no_default_filters option of para_filter has been
599 deprecated. It still works but has no effect and will be
600 removed in the next version.
601 - para_gui now prints also the stderr output of the executing
602 command in the bottom window.
603 - Cleanup and consolidation of the various wrappers for
604 write(), writev(), send() and friends.
605 - The obscure error messages on mmap() failures have been
606 replaced by meaningful messages. This affects mainly
607 para_afh.
608 - para_audioc: Cleanups and memory leak fixes.
609 - Test 0004-server no longer fails if para_server is not
610 being built.
611 - New configure options: --with-id3tag-{headers,libs}.
612
613 -------------------------------------
614 0.4.9 (2011-12-06) "hybrid causality"
615 -------------------------------------
616
617 Support for another audio format, interactive mode for para_client
618 and para_audiod and many small improvements/fixes all over the place.
619
620 - Support for flac, the free lossless audio codec.
621 - Fix for an endless loop in the mp3 decoder for certain
622 (corrupt) mp3 files.
623 - When executed without specifying a command, para_client
624 and para_audioc start an interactive shell (requires
625 libreadline being installed). The interactive mode offers
626 full tab completion and command line history.
627 - autogen.sh now detects a distcc setup and adjusts the
628 parameter for the -j option of make accordingly.
629 - Shared memory areas are no longer restricted to 64K. We now
630 detect the maximal size of a shared memory area at runtime.
631 - cleanup of the internal uptime API.
632 - para_server prefaults the mmapped audio file to avoid
633 delays on slow media.
634 - A new test for the test-suite that exercises the
635 communication between para_server and para_audiod.
636 - The alsa writer eats up less CPU cycles when configured to
637 use the DMIX plugin.
638 - Simplified and unified receiver code.
639 - Makefile cleanups.
640 - Commands which print a list of matching audio files now
641 emit a meaningful error message if no audio file matched the
642 given pattern(s).
643
644 --------------------------------------
645 0.4.8 (2011-08-19) "nested assignment"
646 --------------------------------------
647
648 Gcrypt support, the overhauled osx writer and regex format specifiers
649 are the highlights of this release.
650
651 - support for libgcrypt as a drop-in replacement for openssl.
652 Run configure --enable-cryptolib=gcrypt to link against
653 libgcrypt. The two crypto implementations are compatible to
654 each other, i.e. a para_client executable linked against
655 gcrypt can connect to para_server linked against libssl
656 and vice versa.
657 - Rewrite of the osx writer (output plugin for Mac OS).
658 - audiod: The format specifier for receivers, filters and
659 writers is now treated as a regular expression. This allows
660 to replace 5 lines in the config file (one for each audio
661 format) by one single line. See the manual for details.
662 - The \*.cmdline.[ch] files are no longer contained in the released
663 tarballs. This reduces the size of the tarballs but requires
664 gengetopt to build the tarball.
665 - Compiles cleanly also with llvm/clang.
666 - Corrupt mp3 files are handled more gracefully.
667 - The alsa writer uses poll fds instead of computing timeouts.
668 - Cleanup of the generic writer API.
669 - sched: Optimized zero timeouts.
670 - vss timeout cleanups.
671 - oggdec fixes and improvements.
672
673 --------------------------------------
674 0.4.7 (2011-06-01) "infinite rollback"
675 --------------------------------------
676
677 The new ao writer, support for ssh RSA keys and a couple of other
678 enhancements.
679
680 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
681 platforms through the libao audio library.
682 - Support for RSA keys generated with ssh-keygen.
683 - configure: improved options for ogg/vorbis/speex.
684 - The git version reported by --version always matches HEAD.
685 - The autogen script detects the number of processors and
686 runs a parallel make if possible.
687 - Major cleanup of the crypto API.
688 - Documentation updates.
689
690 ------------------------------------------
691 0.4.6 (2011-03-31) "deterministic entropy"
692 ------------------------------------------
693
694 Lots of ogg/vorbis improvements, the new test suite, enhancements
695 for para_gui and a fair amount of other bug fixes.
696
697 - For DCCP/OGG streams the audio file header is only sent once
698 at the beginning of the stream rather than periodically
699 every five seconds. This reduces network traffic and the
700 FEC group size.
701 - The vorbis comment header is replaced by an empty dummy header
702 before the header is sent over the network. This also results in
703 less network traffic and smaller FEC groups.
704 - The new "test" make target allows to perform some sanity checks prior
705 to installing the package.
706 - ogg timing fixes and performance improvements
707 - Scheduler improvements
708 - Proper exit codes for para_write
709 - para_gui: New option --theme to select a startup theme. Several
710 other improvements and fixes.
711 - aacdec error message cleanups
712 - simplified color error handling
713
714 --------------------------------------------
715 0.4.5 (2010-12-17) "symmetric randomization"
716 --------------------------------------------
717
718 Bug fixes, internal cleanups and variable-sized FEC slices.
719
720 - Contains a fix for an invalid-free-bug in the ogg audio format
721 handler code.
722 - Switching off the DCCP sender works again.
723 - para_audiod handles crashes of para_server more robustly.
724 - Internal scheduler and writer cleanups.
725 - Reduced latency due to variable-sized FEC slices.
726 - Improved documentation and error diagnostics.
727 - The build of para_server is now optional, allowing the build
728 to succeed in case libosl is not installed.
729
730 ------------------------------------------
731 0.4.4 (2010-08-06) "persistent regularity"
732 ------------------------------------------
733
734 Support for yet another audio format, para_write improvements and
735 bug fixes.
736
737 - Support for the speex codec.
738 - Support for sample formats other than 16 bit little endian.
739 - error2.h is now created by a perl script which speeds up configure
740 considerably.
741 - Fix a bug in the aac decoder which could lead to segfaults in
742 para_filter/para_audiod.
743 - Fixes for autoconf-2.66.
744
745 ----------------------------------------
746 0.4.3 (2010-07-05) "imaginary radiation"
747 ----------------------------------------
748
749 Many improvements for the DCCP and the UDP transport, the new user
750 manual and the usual mix of bug fixes and internal improvements.
751
752 - FEC support for the DCCP sender (Gerrit Renker). The new
753 --dccp_max_slice_size, --dccp_data_slices_per_group and
754 --dccp_slices_per_group options can be used to set the FEC
755 parameters for the DCCP transport.
756 - DNS lookups for UDP targets (Gerrit Renker).
757 - The new user manual replaces the README, README.afs, REQUIREMENTS
758 and INSTALL documents.
759 - Fix an end-of-file detection bug in the oggdec filter.
760 - The new nonblock API.
761 - Both options of the oggdec filter have been removed.
762 - New debug mode for the internal scheduler.
763
764 ------------------------------------------
765 0.4.2 (2010-04-23) "associative expansion"
766 ------------------------------------------
767
768 It's been some time since the last release, but finally here is
769 paraslash-0.4.2. The bulk of the changes comes from the new buffer
770 tree API, but there are changes all over the tree. Mainly performance
771 and usability improvements, but also quite some bug fixes.
772
773 - The new buffer tree API.
774 - DCCP: Support for CCID negotiation (Gerrit Renker).
775 - UDP robustness fixes.
776 - The --bufsize option for mp3dec is gone as it no longer makes sense
777 for the new buffer tree API.
778 - Fix audible buffer underruns for wma streams.
779 - The alsa writer no longer prints meaningless underrun durations.
780 - audiod: Defaults work also for udp streams. If no filter is
781 given for an audio format that is received via upd, fecdec is
782 automatically added as the first filter (along with the decoder).
783
784 ---------------------------------------
785 0.4.1 (2009-12-22) "concurrent horizon"
786 ---------------------------------------
787
788 Support for another audio format, minor feature enhancements and lots of bug
789 fixes. All fixes that have been accumulated in the maint branch (in particular
790 those mentionened in the 0.3.6 release notes) appear in this release as well.
791
792 - wma support.
793 - new afh option: --human to activate human-readable output.
794 - new server/audiod option: --log-timing to print timing information.
795 - build system improvements.
796 - source code documentation updates.
797
798 -------------------------------------
799 0.3.6 (2009-12-07) "cubic continuity"
800 -------------------------------------
801
802 Quite a few bugs have been found and fixed since 0.3.5, so here's
803 another 0.3.x release. No new features.
804
805 - Always check return value of malloc().
806 - ogg vorbis/FEC: Do not write garbage after the audio file header.
807 - exit if root privileges could not be dropped.
808 - FEC: Fix computation of extra slices.
809 - oss: Fix check for empty input buffer.
810 - Avoid buffer underruns due to filter chain output buffer constraints.
811 - server: Fix assignment of afs_pid.
812 - Don't panic if the afs database contains unknown audio formats.
813 - http/dccp: Do not send the audio file header twice.
814 - FEC: Timing improvements.
815
816 ----------------------------------------------
817 0.4.0 (2009-11-10) "simultaneous independence"
818 ----------------------------------------------
819
820 Two significant changes which require the new version number: The
821 improved authentication dialog and the fact that the database code
822 has been moved to a library, libosl. To use the new version, you have
823 to generate new RSA keys, see INSTALL for details. A shell script is
824 provided for conversion of the 0.3 database to the new 0.4 format.
825
826 - stronger crypto for client authentication
827 - the database code has been moved to a library
828 - improved status item handling
829 - cleanup of the build system
830 - The "-V" option now also prints the git version
831 - the new parser-friendly listing mode for the ls and stat commands
832 - mandatory rc4 encryption
833 - major audio format handler cleanups
834 - (id3,...) tags are no longer stored as a combined string in the database
835 - new mood methods: artist_matches, title_matches, comment_matches,
836 album_matches, year_maches, year.
837
838 --------------------------------------------
839 0.3.5 (2009-09-21) "symplectic separability"
840 --------------------------------------------
841
842 Full client support for \*BSD Unixes, complete re-write of the ogg
843 vorbis audio format handler, various improvements all over the place
844 and the usual mix of bugfixes. This release marks the end of the 0.3
845 series if no serious problems show up.
846
847 - the new oss writer (supported on \*BSD and Linux)
848 - rewrite of the ogg vorbis audio format handler. It's
849 recommended to replace the chunk tables of existing ogg
850 vorbis files in the afs database by re-adding these files
851 with "add -f".
852 - support for netmask subsets (Gerrit Renker)
853 - the new prebuffer filter
854 - improved signal handling
855 - variable fec output buffer size
856 - improved FEC timing fixes audible buffer underruns in UDP mode
857 - --log_color actually works
858 - new ls option: -d (print dates as seconds after the epoch)
859 - update to gengetopt 2.22.2
860 - support for RSA keys of size > 512 bits
861 - new option "mixer_channel" for para_fade
862
863 -----------------------------------------
864 0.3.4 (2009-05-07) "elliptic inheritance"
865 -----------------------------------------
866
867 The new udp sender, forward error correction, colored logs and various
868 other improvements. As the udp sender does not depend on any special
869 libraries, it is built unconditionally.
870
871 - The udp sender replaces the ortp sender. The new code uses forward
872 error correction to protect against packet losses. Many thanks to
873 Gerrit Renker for providing ipv6 support.
874 - The default port for udp streaming now defaults to 8000, like
875 for the http and the dccp senders/receivers.
876 - Loglevels are now specified as symbolic names, e.g.
877 "--loglevel info".
878 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
879 - para_server/para_audiod: Color support for log messages.
880 - new options for mp3dec: --ignore-crc, --bufsize
881 - new audiod option: --config-file.
882 - gengetopt cleanups.
883 - Improved help/man pages: The documentation of para_audiod,
884 para_recv, para_filter and para_write now also contains
885 all options of the available receivers/filters/writers. The
886 man page of para_fade contains a description of the different
887 modes of operation.
888 - More source code documentation.
889 - vss timing fixes.
890
891 --------------------------------------------
892 0.3.3 (2008-12-01) "axiomatic perspectivity"
893 --------------------------------------------
894
895 Internal code cleanups, bug fixes, improved tag handling and the new
896 amplification filter.
897
898 - para_server uses the generic scheduling code.
899 - overhaul of the virtual streaming system.
900 - mp3: id3 version 2 support via libid3tag (optional)
901 - ogg: vorbis comment support.
902 - aac meta info support.
903 - mp3 audio format handler cleanups.
904 - new filter: "amp" to amplify the amplitude of the audio stream
905 - new status item/database entry: amplification. It is
906 used by the amp filter to pre-amplify the audio stream.
907 - fix a close-without-open bug in para_write.
908 - fix a bug in com_init() which was introduced in 0.3.2.
909 - better error diagnostics for para_client.
910
911 -----------------------------------------
912 0.3.2 (2008-04-11) "probabilistic parity"
913 -----------------------------------------
914
915 The new para_afh executable, scheduling and documentation improvements.
916
917 - new ls option: -lc (list chunk table)
918 - new executable: para_afh, the stand-alone audio file handler tool
919 - afs commands can send output more than SHMMAX (32MB on Linux). This
920 also reduces the memory usage of commands that produce large amounts
921 of output.
922 - major scheduler and audiod cleanups.
923 - more detailed and much nicer man pages.
924
925 ---------------------------------------
926 0.3.1 (2008-02-23) "liquid interaction"
927 ---------------------------------------
928
929 A mix of cleanups, bug fixes, improvements, and some new features. No
930 significant changes to the new database (osl) code, which is generally
931 a good sign.
932
933 - Share some similar/duplicate code between the http and the
934 dccp sender.
935 - Generic access control lists for paraslash senders.
936 - dccp sender: Access control lists, connection limiting and support
937 for the allow,deny,on,off,help sender commands.
938 - The default dccp port changed from 5001 to 8000 (suggested by
939 Gerrit Renker).
940 - para_server starts even if not all public keys could be loaded.
941 - Audiod performance improvements.
942 - fix a bug in the "off" command of the http sender.
943 - fix some fd and memory leaks.
944 - Update to gengetopt-2.22.
945
946 -------------------------------------
947 0.3.0 (2008-01-12) "solar saturation"
948 -------------------------------------
949
950 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
951
952
953 Usually one might expect lots of new features AND a big increase in size
954 for a major release like this.
955
956 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
957 ever. The decrease in size is mostly due to the removal of some
958 graphical tools (which were only quick hacks anyway). But also the
959 fact that the mysql code is gone cuts down the size a bit.
960
961 Being independent of mysql comes at a cost: The fact that paraslash
962 now contains its own database (the object storage layer, osl) increases
963 the (stripped) binary size of para_server by ~50K on i386.
964
965 - no more restrictions on unique basenames.
966 - independent of mysql: The new self-contained object
967 storage layer (osl) replaces the mysql database.
968 - New executable para_fsck: Check integrity of osl tables.
969 - Lyrics support.
970 - Reliable audio file move/rename detection.
971 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
972 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
973 Solaris (sparc64).
974 - the new osl-based audio file selector (afs) replaces the random,
975 the playlist and the mysql selector of paraslash-0.2.x.
976 - IPv6 support (thanks to Gerrit Renker).
977 - paraslash-0.2.x streams are now called "moods". Writing
978 0.3.x-mood definitions should be both easier and more
979 powerful than writing 0.2.x-stream definitions.
980 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
981 been removed. The world is a better place without them. However,
982 para_gui is still there.
983 - afs tracks audio file selection also in playlist mode.
984 - few easy-to-use afs commands replace the many not-so-easy-to-use
985 mysql commands (and are available also in playlist mode).
986 - Improved error subsystem.
987 - The earth-shaking new logo.
988
989 -----------------------------------------
990 0.2.17 (2007-11-20) "isotropic threshold"
991 -----------------------------------------
992
993 Mainly bugfixes and cleanups in this version which marks the end of
994 the 0.2.x series if no serious bugs show up after the release.
995
996 - mysql_selector: fix a locking bug.
997 - universal chunk queueing.
998 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
999 to Gerrit Renker).
1000 - be more carful wrt. signed vs. unsigned argument passing.
1001 - cleanup error.h and fix some references to invalid error
1002 codes.
1003 - update to gengetopt-2.21.
1004 - update to ortp-0.13.1.
1005 - autoconf: extend checks for headers, library functions and
1006 compiler characteristics.
1007 - Fix streaming of large mp3 files.
1008 - Fix an off-by-one bug in playlist handling.
1009
1010 --------------------------------------
1011 0.2.16 (2007-04-05) "neural discharge"
1012 --------------------------------------
1013
1014 The main change in this release is the major audio format handler
1015 cleanup which removes some similar/duplicate code and makes it easier
1016 to implement plugins for other audio formats. Of course, the usual mix
1017 of other improvements/changes/bugfixes also made it into the release.
1018
1019 - simplified audio format handlers (most of the handling functions
1020 were moved one layer up to the virtual streaming system).
1021 - para_server uses mmap to read audio files
1022 - repositioning of mp3 streams is much faster, in particular for
1023 jumping near the end of large mp3 files.
1024 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
1025 and AFS_WRITE.
1026 - fix a bug in para_filter that caused decoding of aac files
1027 to start only after a few seconds.
1028 - fix osx_writer hangs
1029 - simplified dccp code (thanks to Gerrit Renker)
1030 - the compress filter works also on big endian systems (ppc)
1031
1032 -----------------------------------------
1033 0.2.15 (2007-02-16) "inductive resonance"
1034 -----------------------------------------
1035
1036 Minor improvements, more documentation and a bunch of bug fixes.
1037
1038 - para_server: The server.users file is only read once on server
1039 startup rather than for each connection
1040 - mp3dec: Fix decoding of corrupt mp3 files
1041 - afs (audio file sender) is now called vss (virtual streaming
1042 system). Consequently, the permission flags specified in
1043 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
1044 become VSS_READ and VSS_WRITE respectively.
1045 - para_audiod/para_filter: Fix a bug that caused the last chunk
1046 of audio data not being written under certain circumstances
1047 - audiod: compute the difference of server time and local time
1048 correctly
1049 - para_server/para_audiod: Fix some memory leaks
1050 - documentation improvements
1051 - configure.ac: fix checks for para_krell
1052 - new man pages
1053
1054 -------------------------------------------
1055 0.2.14 (2006-10-15) "transient singularity"
1056 -------------------------------------------
1057
1058 The only major enhancement of this version is the osx writer which completes
1059 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
1060 until now for reasons beyond the scope of this changelog entry.
1061
1062 - new output plugin for Mac Os: the osx writer
1063 - rename configure command line options from --enable-xxx-headers to
1064 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
1065 - configure: new command line options: --with-mad-headers,
1066 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
1067 - some robustness fixes
1068 - dymamic audio format recognition for audiod
1069 - para_server: new command line option: --autoplay_delay
1070 - para_audiod: new command line option: --clock_diff_count
1071
1072 ---------------------------------------
1073 0.2.13 (2006-07-14) "sonic convolution"
1074 ---------------------------------------
1075
1076 A bunch of new features and core changes.
1077
1078 - the new paraslash scheduler, short and sweet.
1079 - Support for m4a/mp4 files via the new aac audio format
1080 handler/filter (requires libfaad).
1081 - each writer has its own command line parser, just like
1082 para_recv and para_filter.
1083 - para_client and para_audioc use the error subsystem
1084 - writers are integrated in para_audiod (currently linux-only)
1085 - para_client is integrated in para_audiod
1086 - random/playlist selector: improved info strings
1087 - new audiod commands: tasks, kill
1088 - update to libortp-0.10.1
1089 - para_fade: wake time defaults to 8 hours from now
1090 - update to autoconf-2.60
1091
1092 ------------------------------------------
1093 0.2.12 (2006-05-12) "oriented abstraction"
1094 ------------------------------------------
1095
1096 Many user-visible changes in this release and lots of new
1097 features:
1098
1099 - the new optional dccp sender/receiver. It uses the datagram
1100 congestion control protocol. You'll need a fairly new kernel
1101 for this.
1102 - paraslash works on Mac OS X (thanks to Gerd Becker)
1103 - para_play renamed to para_write
1104 - modular output plugin design (writers) for para_write
1105 - new file_writer output plugin for para_write
1106 - compress filter speed improvements
1107 - update to libortp-0.9.1
1108 - update to gengetopt-2.17rc
1109 - para_client no longer depends on libreadline (as the
1110 code for the interactive mode was removed).
1111 - gcc-2-95 is no longer a supported compiler. It may still
1112 work, but it gets no more testing.
1113 - the tarball no longer contains the screenshot images which
1114 reduces its size quite a bit.
1115 - configure: new command line options: --enable-mysql-headers
1116 and --enable-mysql-libs
1117
1118 ------------------------------------
1119 0.2.11 (2006-03-11) "atomic duality"
1120 ------------------------------------
1121
1122 Here it is, the first paraslash release developed with git. There
1123 are fairly many user-visible changes in this release. As two out of
1124 the three "database tools" of paraslash don't use a database at all,
1125 they are now called "audio file selectors" instead.
1126
1127 - the cdt command (change database tool) becomes chs (change
1128 selector)
1129 - no more colon separators: The syntax of some options of
1130 para_audiod and para_filter have changed. Use --help for
1131 more info (and some examples).
1132 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
1133 - switch from cvs to git (should've done that earlier)
1134 - the new ipc subsystem
1135 - new audio file selector: playlist
1136 - para_server: the dopey selector is now called "random",
1137 and is the default selector. Use the --selector option to
1138 choose another selector at startup, or the chs command to
1139 change the selector at runtime.
1140 - X86_64 fixes (thanks to Steffen Klassert)
1141 - para_play fixes
1142
1143 --------------------------------------
1144 0.2.10 (2006-02-17) "cyclic attractor"
1145 --------------------------------------
1146
1147 Huge documentation update, a scrollable window for para_gui, ortp
1148 improvements, and of course many small fixes not mentioned here.
1149 The diffstat below is rather misleading as most insertions are due
1150 to the new source documentation.
1151
1152 - autoconf cleanup
1153 - para_server also uses the new error subsystem
1154 - lots of new documentation (UTSL)
1155 - gui improvements:
1156 - keysyms for cursor keys and for next/previous page keys
1157 - scrollable output window
1158 - new internal commands: scroll up/down, page up/down
1159 - fix color of command output.
1160 - ortp: the --chunk_time and --header flags are no longer needed
1161 for para_recv/para_audiod as this information is now encoded in
1162 each rtp packet sent by para_server.
1163
1164 -------------------------------------------
1165 0.2.9 (2006-01-24) "progressive turbulence"
1166 -------------------------------------------
1167
1168 Internal audiod receivers/filters, the new error subsystem and
1169 a lot of small improvements.
1170
1171 - para_recv and para_filter are integrated into the para_audiod
1172 binary, i.e. audiod no longer spawns a new process for
1173 each receiver/filter. As para_recv and para_filter might be
1174 useful as standalone programs, they still get built (linked
1175 against the same object files that are also used for audiod).
1176 - further ortp timing improvements should reduce the CPU usage
1177 of the ortp receiver.
1178 - improved audio grabbing. The 'grab' command of para_audiod
1179 has its own set of command line options. Read the output of
1180 "para_audioc help grab" for more info.
1181 - oggdec: configurable input prebuffer size.
1182 - the new error subsystem gives better error diagnostics
1183 and reduces code size.
1184
1185 -----------------------------------------
1186 0.2.8 (2006-01-02) "dynamic accumulation"
1187 -----------------------------------------
1188
1189 The new modular filter design and the para_play-hangs bugfix.
1190
1191 - new executable: para_filter. It combines para_mp3dec,
1192 para_oggdec and para_compress. It also adds a further filter
1193 type, wav, that just inserts a wave header at the desired point
1194 of the filter chain. All 'piping' is done in-memory (i.e. no
1195 read/write operations are used).
1196 - para_play: fix a stupid bug that caused it to hang under
1197 certain circumstances.
1198
1199 -------------------------------------------
1200 0.2.7 (2006-12-27) "transparent invariance"
1201 -------------------------------------------
1202
1203 Not many user-visible changes but a fair amount of internal improvements.
1204
1205 - The http sender buffers data if it can not be sent
1206 out immediately (because the socket is not writable). This
1207 should prevent para_server from shutting down the connection
1208 too early on a loaded network.
1209 - para_play also prebuffers data if it is told to start at a
1210 future time by the --start_time option.
1211 - The return of para_recv: It combines para_ortp_recv and
1212 para_http_recv. Use the --receiver option to switch between
1213 the two. para_recv builds without libortp, but contains
1214 only the http receiver in this case.
1215 - update to ortp 0.8.1. As this ortp release contains incompatible
1216 changes, para_recv-0.2.7 won't link against older ortp libs.
1217 - improved ortp timings.
1218 - use of gcc-extensions that #define away for non-gcc and
1219 gcc < 3.0.
1220
1221 -------------------------------------------
1222 0.2.6 (2005-10-29) "recursive compensation"
1223 -------------------------------------------
1224
1225 Transparent session encryption (uses openssl's Alleged RC4 cipher),
1226 the internal find command and several other improvements and cleanups.
1227
1228 - Encrypt the session if encryption is requested by the client
1229 (default for para_client 0.2.6). This is backwards
1230 compatible, so older clients can still connect to para_server
1231 0.2.6. Use the new client option --plain to request an
1232 uncrypted session (off by default, must be set to on in
1233 order to connect to para_server 0.2.x with 0 <= x <= 5).
1234 - para_server uses an internal function to locate audio files
1235 rather than calling find(1). The server option
1236 --mysql_audio_file_dir replaces --mysql_find_cmd.
1237 - documentation update
1238 - man pages
1239 - header file cleanup
1240 - para_client code cleanup
1241 - para_gui: faster display of output of display commands
1242
1243 ------------------------------------------
1244 0.2.5 (2005-10-13) "aggressive resolution"
1245 ------------------------------------------
1246
1247 This release adds internal senders, i.e. no more external programs are
1248 spawned for sending out the audio data. There are two different senders
1249 available: The http sender and the ortp sender (former para_send which
1250 is no longer needed).
1251
1252 The new sender code has a plugin-like design so it can be easily
1253 extended should there be be any future need for supporting another
1254 network streaming protocol. All senders are completely independent of
1255 each other. In particular, the http and the ortp sender can operate
1256 in parallel.
1257
1258 - new server command: sender to control senders at runtime.
1259 Read the output of "para_server -h" and "para_client help
1260 sender" for more information.
1261 - para_recv renamed to para_ortp_recv
1262 - new executable: para_http_recv, a simple command line
1263 http receiver.
1264 - major afs/mp3/ogg code simplifications due to internal
1265 senders.
1266 - ogg timing improvements
1267 - fix several minor memory leaks (found by valgrind)
1268 - empty stream definitions work again
1269 - com_ne(): ignore errors on remove
1270 - audiod: fix segfault on server restart
1271
1272 ---------------------------------------
1273 0.2.4 (2005-09-21) "toxic anticipation"
1274 ---------------------------------------
1275
1276 Several small improvements, fixes and the new grab command.
1277
1278 - audiod:
1279 - new command: "grab" to grab the output of the stream reader
1280 or any filters. Read the output of "para_audioc help grab"
1281 for more information.
1282 - fix memory leak
1283 - code cleanup
1284 - audioc: new command line option: --bufsize to specify a
1285 buffer size different from the default size 8192.
1286 - improved error diagnostics for para_play.
1287 - new configure option: --enable-ssldir so search for openssl in
1288 non-standard places
1289 - sdl_gui: Make it look nice again for 1024x768
1290 - server: report total size of memory allocated with sbrk by malloc,
1291 new command line option: --announce_time
1292
1293 -----------------------------------------
1294 0.2.3 (2005-09-01) "hydrophilic movement"
1295 -----------------------------------------
1296
1297 Two new executables and major feature enhancements.
1298
1299 - audiod filters: It is now possible to specify arbitrary many
1300 (including none) filters for each supported audio
1301 format. This can be used e.g. for normalizing volume,
1302 transforming or grabbing the audio stream, or for using
1303 visualizers. Read the output of "para_audiod -h" for the
1304 syntax of the new --filter_cmd option.
1305 - new executable: para_play, a tiny alsa player. It
1306 can play wave files or raw pcm (16 bit little endian)
1307 from stdin.
1308 - new executable: para_compress, a dynamic range compressor
1309 intended to keep audio output at a consistent volume. Derived
1310 from [AudioCompress](http://trikuare.cx/code/AudioCompress.html).
1311 - audiod: New option: --stream_delay. This can be used in
1312 a local network to syncronize the audio output of all
1313 clients that play the same stream.
1314
1315 ------------------------------------------
1316 0.2.2 (2005-08-19) "tangential excitation"
1317 ------------------------------------------
1318
1319 Mostly internal changes in this release, but also some new commands
1320 for the mysql database tool.
1321
1322 - cleanup exec.c, fix para_exec bug
1323 - compile time loglevel (log messages below the given level
1324 won't be compiled in, which reduces the size of the
1325 resulting binaries)
1326 - new log macros that shorten the size of the source code.
1327 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
1328 to send only zeros. With this workaround, para_audioc works
1329 again.
1330 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
1331 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
1332 (new entry), "snp" (set numplayed). Read the manual for more
1333 information.
1334
1335 ---------------------------------------
1336 0.2.1 (2005-08-15) "surreal experience"
1337 ---------------------------------------
1338
1339 Here comes paraslash-0.2.1. It contains a couple of new features and,
1340 surprise, only minor bug fixes.
1341
1342 - kill noisy mp3 debug message
1343 - cleanup of the build system
1344 - para_server and para_client directly use the crypto routines
1345 of the openssl library rather than invoking the openssl command
1346 line utitlity
1347 - server/audiod: new option --user to switch to the given user
1348 when invoked as root. Read the output of "para_server -h" for
1349 more information.
1350 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
1351 status. Default: "para_audioc stat"
1352 - sdl_gui: new option --pic_cmd to be used to download the picture.
1353 Default: "para_client pic"
1354 - audiod: 5 slots ought to be enough for everybody
1355 - audiod: new status item: Uptime, kill hup command
1356
1357 ------------------------------------------
1358 0.2.0 (2005-08-06) "distributed diffusion"
1359 ------------------------------------------
1360
1361 After several month of increased development activity, paraslash-0.2.0
1362 has arrived. It contains many new features and is much more
1363 self-contained than the old 0.1.x series. Enjoy!
1364
1365 - para_server: fix hang on song change and crash on sighup.
1366 Speed up mysql queries. The DIR_LIKE macro is gone.
1367 - new executables: para_audiod, the local audio daemon that
1368 starts playback (uses SCM_CREDENTIALS socket magic) and
1369 para_audioc, the corresponding client.
1370 - new executables: para_mp3dec/para_oggdec, two really teensy
1371 decoders. para_mp3dec is based on libmad, para_oggdec requires
1372 libvorbisfile.
1373 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
1374 they are now called para_send and para_recv respectively.
1375 - documentation updates
1376 - para_gui is themable. For now there is the default theme that
1377 looks as before and the simple theme: blue and easy.
1378 - gui: audio streaming is now handled by audiod. Time display shows
1379 playback time rather than streaming time
1380 - slider: update to libzmw-0.2.0
1381 - para_krell: fix crash on server shutdown
1382 - switch from gzip to bzip2
1383
1384 ----------------------------------------
1385 0.1.7 (2005-04-18) "melting penetration"
1386 ----------------------------------------
1387
1388 The main change in this release is clearly the oggvorbis rewrite,
1389 but there are also lots of smaller changes. If you intend to use both
1390 the mp3 and the ogg plugin, it is recommended to use software mixing,
1391 e.g. the dmix plugin which is provided by ALSA.
1392
1393 - new executables: para_ovsend and para_ovrecv for sending/receiving
1394 oggvorbis files via rtp. Requires the open rtp library. Get it at
1395 http://www.linphone.org/ortp/
1396 - rewrite of the ogg_vorbis core code
1397 - configure detects libzmw and, if detected, includes
1398 para_slider to the list of binaries to be built by make
1399 - server stream writers read from their associated fifo rather
1400 than from stdin
1401 - slider: two new sliders, lastplayed and numplayed
1402 - fix nasty double free bug which caused random segfaults in case of
1403 mp3 files with invalid header information
1404 - gui: new command line option: --stream_timeout=seconds to
1405 deactivate a slot if it is idle for that many seconds (default=`5')
1406 - diffstats
1407
1408 ---------------------------------------
1409 0.1.6 (2005-03-05) "asymptotic balance"
1410 ---------------------------------------
1411
1412 Only little user-visible changes in this release. Mainly bugfixes and
1413 core code cleanup. This is probably the most stable version ever if you
1414 stick to mp3...
1415
1416 - fix several memory leaks
1417 - rename default name of mysql database from "music" to "paraslash".
1418 Use para_server's --mysql_database option if you do not want to
1419 rename your old database.
1420 - rework ogg vorbis code
1421 - make update command work on mysql servers with LOCAL_INFILE
1422 disabled
1423 - gui: improved stream I/O (slots)
1424 - simplified audio format API
1425 - para_pob_ogg is gone
1426
1427 ------------------------------------
1428 0.1.5 (2004-12-31) "opaque eternity"
1429 ------------------------------------
1430
1431 Let's slide gently into the new year.
1432
1433 - new: para_slider (not built automatically, type "make
1434 para_slider" to build). A toy for those who always felt that
1435 creating stream definitions is difficult. See screenshots,
1436 README and FEATURES for more info.
1437 - improved signal handling. Fixes server segfault on SIGHUP
1438 for linux kernels newer than Aug 24 2004 and makes para_gui
1439 race-free.
1440 - reload database tool on SIGHUP
1441 - improved help message for sl
1442 - do not log "broken pipe" messages as errors. They are
1443 perfectly ok.
1444 - fix wrong error message on permission errors
1445
1446 -----------------------------------------
1447 0.1.4 (2004-12-19) "tunneling transition"
1448 -----------------------------------------
1449
1450 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1451 Hopefully, most of them got wiped out with this release. Some
1452 enhancements went also in.
1453
1454 - improved error diagnostics for all commands
1455 - stradd/picadd: overwrite previous contents if entry already
1456 exists, rather than returning errors
1457 - stradd: use current stream if invoked without args
1458 - faster (and hopefully more stable) ogg-vorbis handling
1459 - para_krell: reap children to avoid zombie-flooding in case
1460 no server is running
1461 - si: report also server pid
1462 - server: don't busy-loop if dbtool reports only invalid files.
1463 - gui: CTRL+C works again, fix stream_read command line option
1464 - fix pic_add, hist
1465 - fix mysql dbtool startup in case no database exists
1466 - many small fixes and cleanups
1467
1468 ---------------------------------------
1469 0.1.3: (2004-12-10) "vanishing inertia"
1470 ---------------------------------------
1471
1472 Starting from this release, the database tools are integrated in the
1473 server binary. This decreases server startup time, reduces code size
1474 and speeds up database commands. However, the layout of the underlying
1475 mysql database changed only slightly and 0.1.3 should be backwards
1476 compatible in that respect.
1477
1478 Visible changes:
1479
1480 - If mysql is not detected at compile time, or fails to init
1481 at runtime, fall back to the dopey database tool which should
1482 always work.
1483 - para_dbtool and dbtool.conf are gone. All mysql specific
1484 options are read from server.conf and are prefixed by 'mysql_'.
1485 - new command: cdt (change database tool)
1486 - new command line option: dbtool (choose startup database tool)
1487 - The name of current stream is now stored in the database,
1488 so paraslash remembers its current stream when restarted.
1489 - new command: csp (change stream and play)
1490 - para_gui also reports current database tool and server uptime
1491
1492 -------------------------------------------
1493 0.1.2: (2004-11-28) "spherical fluctuation"
1494 -------------------------------------------
1495
1496 Point release before the big dbtool changes go in.
1497
1498 - dbtool: rename ca to cam (copy all meta data). It now also
1499 copies numplayed and lastplayed time as well as the picture
1500 id.
1501 - fix endless-loop-bug caused by mp3 files with invalid header
1502
1503 -----------------------------------------
1504 0.1.1: (2004-11-05) "floating atmosphere"
1505 -----------------------------------------
1506
1507 - gkrellm plugin
1508 - new dbtool command: mbox. Browse your sound-file collection
1509 with your favorite mail reader.
1510 - several small fixes
