5 0.6.3 (to be announced) "generalized activity"
6 ----------------------------------------------
7
8 - The ff command now accepts a negative argument to instruct the
9 virtual streaming system to jump backwards in the current audio
10 stream. The old syntax (e.g., "ff 30-") is still supported but it
11 is deprecated and no longer documented. The compatibility code is
12 sheduled for removal after 0.7.0.
13 - para_afh: New option: --preserve to reset the modification time to
14 the value of the original file after meta data modification.
15 - Overhaul of the compress filter code. The refined algorithm should
16 reduce clipping. The meaning of --aggressiveness has changed, see the
17 updated and extended documentation of the compress filter for details.
18 - Cleanup of the audio format handler code.
19 - We now build the tree using the .ONESHELL feature of GNU make,
20 which results in a significant speedup.
21 - Two robustness fixes for FreeBSD.
22 - para_client now supports RFC4716 private keys as generated with
23 ssh-keygen -m RFC4716. In fact, this key format has been made the
24 default, and the former PEM keys will be depreciated at some point.
25
26 --------------------------------------
27 0.6.2 (2018-06-30) "elastic diversity"
28 --------------------------------------
29
30 The main new feature of this release is the --listen-address option
31 for para_server and para_audiod. But there are also a large number of
32 small improvements and bug fixes all over the place. The user-visible
33 changes include
34
35 - para_gui no longer waits up to one second to update the screen when
36 the geometry of the terminal changes.
37 - Minor documentation improvements.
38 - Improvements to the crypto subsystem.
39 - The server subcommand "task" has been deprecated. It still works,
40 but prints nothing. It will be removed in the next major release.
41 - Server log output is now serialized, avoiding issues with partial
42 lines.
43 - It is now possible to switch to a different afs database by changing
44 the server configuration and sending SIGHUP to the server process.
45 - New server options: --listen--address, --http-listen-address and
46 --dccp-listen-address. These options restrict the set of listening
47 addresses of the TCP and DCCP sockets of the server process.
48 - The help commands of server, audiod, play now support --long. By default,
49 the short help is shown.
50 - The code which merges the command line options with the config file
51 options has been consolidated.
52 - If the current audio file is renamed, the status items are now updated
53 accordingly.
54 - After the server process received SIGHUP, changes to the current audio
55 file did not trigger an update of the status items. This has been fixed.

61 ----------------------------------------
62 0.6.1 (2017-09-23) "segmented iteration"
63 ----------------------------------------
64
65 The highlight of this release is the version 2 mood parser. But there
66 is a lot more than that, as summarized in the list below. And of
67 course we have many small usability improvements and bug fixes not
68 mentioned here.
69
70 - A more intuitive syntax for moods ("version 2 moods"). The
71 traditional version 1 moods are still supported but are deprecated
72 now. Removal of the version 1 mood parser is scheduled for the next
73 major release.
74 - Flex and bison are now required to build para_server.
75 - New sort order for the ls command: -s=h sorts the ls output by hash
76 value of the audio file.
77 - autogen.sh now runs the test suite after a successful build.
78 - The contents of overview.pdf have been integrated into the user
79 manual.
80 - Fixed sized audio format headers for ogg/opus streams.
81 - The doxygen source browser has been disabled temporarily. The
82 API reference is still online, though.
83 - Overhaul of the source code documentation.
84 - The deprecated --full-path option of the ls command has been
85 removed. It was a no-op since 0.6.0.
86 - The wma decoder has been cleaned up and its bitstream API made
87 more robust.
88 - The image/lyrics ID status items of the current audio file are now
89 updated on changes. This affects para_gui, which used to report the
90 old value until EOF.

97 0.5.8 (2017-09-23) "branching parabola"
98 ---------------------------------------
99
100 A couple of fixes for serious old bugs have accummulated in the maint
101 branch since paraslash-0.5.7 was released nine months ago. So here
102 is another 0.5.x release. As usual, all commits in the maint branch
103 have been merged into master, so the upcoming paraslash-0.6.1 also
104 contains them. For details see the git log.

110 -------------------------------
111 0.6.0 (2017-04-28) "fuzzy flux"
112 -------------------------------
113
114 The highlights of this release are the conversion of all option parsers
115 to the lopsub library and the improved AAC support. But there are
116 many other user-visible changes all over the place. Also a lot of
117 old cruft has been removed, leading to incompatible changes. Hence
118 the new major version number.
119
120 - Support for Mac OS X has been removed.
121 - On Linux systems, glibc-2.17 or newer is required to build the
122 source tree.
123 - Support for RSA public keys in ASN format (as generated by openssl
124 genrsa) has been removed. These keys have been deprecated since
125 2011, so users should have long switched to keys generated with
126 ssh-keygen(1).
127 - If libgcrypt is used as the crypto library, we now require version
128 1.5.0 (released in 2011) or later.
129 - The insecure RC4 stream cipher has been removed. It was superseded
130 by aes_ctr128 three years ago but the RC4 code had been kept for
131 backwards compatibility.
132 - On Linux, abstract unix domain sockets are used unconditionally.
133 - The "install" target no longer strips executables, the new
134 install-strip target can be used to get the old behaviour.
135 - The clean targets have been renamed: clean2 is gone, and the new
136 mostlyclean removes only the executables and object files.
137 - New target: check (identical to test).
138 - The DESTDIR make variable is honored to prepend a path to the
139 installation directory. This feature is orthogonal to the --prefix
140 option to configure.
141 - Minor WMA cleanups.
142 - The aac audio format handler has been rewritten to use the mp4ff library.
143 See the manual for how to install the library on your system.
144 - New status item: max_chunk_size. The value is stored in a previously
145 unused field of the afhi object of the aft table. Although backwards
146 compatible, users are encouraged to re-add m4a files to populate
147 the new field.
148 - No more chunk tables for aac. Chunk boundaries are determined
149 dynamically at stream time.
150 - Release and master branch tarballs are now compressed with xz rather
151 than bzip2.
152 - The lopsub package is required to install the paraslash package.
153 Gengetopt is no longer needed.
154 - make dep is gone. Dependencies have been created automatically for
155 a long time and it was never necessary to run make dep manually.
156 - para_gui lost its --timeout option.
157 - Most manual pages have been extended to include an overall
158 description of the command.
159 - The --stream-delay option of para_audiod has been removed. It had
160 been a no-op for many years.
161 - The deprecated --path option of the server ls command has been
162 removed. The command now prints full paths by default, making
163 --full-path a no-op. Hence --full-path has been depreacted and is
164 scheduled for removal in v0.6.1.
165 - It is now possible to use 'CFLAGS' to override the default compiler
166 options.
167 - para_fade has been renamed to para_mixer. The four modes of operation
168 (set, fade, snooze, sleep) are implemented as subcommands of the
169 new program.
170 - The sleep subcommand of para_mixer (former sleep mode of para_fade)
171 lost its --wake-hour and --wake-min options in favor of the new
172 --wake-time option which also accepts relative wakeup times like
173 "+9:30".
174 - The new --fade-exponent option of para_mixer allows for non-linear
175 channel fading.
176 - The new logo.

183 0.5.7 (2016-12-31) "semantic density"
184 -------------------------------------
185
186 Mostly a bug fix release, and a bunch of internal improvements.
187 The only user-visible changes are the sanity checks for the touch
188 command and the new options to the ls command.
189
190 - Speedup of the base64 decoder.
191 - One of the two source browsers has been removed from the web pages.
192 The doxygen API reference still contains an HTML version of each
193 source file.
194 - Two race conditions in para_server have been fixed.
195 - ls -p is now deprecated in favor of -F or -b. See the help text of
196 the ls command for details.
197 - The openssl code has been adjusted to work also with openssl-1.1.
198 - The wma decoder and audio format handler now correctly decodes
199 files with unusual block sizes.
200 - We now compile with -Wformat-signedness if possible.
201 - The touch command now refuses to set an invalid image or lyrics ID.
202 - New section on contributing for the user manual.
203 - Major simplification of the error subsystem.

210 0.4.14 (2016-12-31) "branching oscillation"
211 -------------------------------------------
212
213 Many fixes for nasty bugs have accumulated over the years since 0.4.13
214 was released in 2013. This release contains all of them. It is the
215 last v0.4.x release, so v0.4.x is now end of life. The maint branch
216 of the git repository has been forwarded to v0.5.7 and will start to
217 receive important fixes for 0.5.x, which is now in maintenance mode.
218
219 - Fix for the "double encryption bug" with gcrypt, which caused
220 garbage to be sent to stat clients.
221 - The "prev" command of para_play now works as expected.
222 - Invalid parameters for the begin and end chunk no longer cause
223 the afh receiver of para_recv to segfault.
224 - A fix for an assertion that triggered in the FEC slice setup code.
225 - Closing the terminal with a running para_gui causes the process to
226 die, rather than using 100% of CPU time.
227 - para_gui no longer shows stale information about the previous
228 audio file.
229 - A fix for a bug in the fec decoder which caused aborts if the buffer
230 pool filled up.
231 - The assertion in the buffer tree code no longer triggers.
232 - The "afs_event: table moods, event 0: key already exists in rbtree"
233 error no longer occurs on attribute changes.
234 - A NULL pointer dereference in com_sender() has been fixed.
235 - The -i option of lsatt works as advertised.
236 - Various fixes for the build system.

243 0.5.6 (2016-07-10) "cascading gradient"
244 ---------------------------------------
245
246 The highlight of this release is the new -m flag for para_afh which
247 lets it modify the meta tags of the given audio file(s). This feature
248 is supported for all audio formats. Many small cleanups and bug fixes
249 not mentioned here have accumulated and are also part of the release.
250
251 - para_afh learned to modify meta tags of mp3 wma ogg spx
252 opus flac aac files.
253 - afs commands propagate error codes to the client.
254 - The check command now also checks the attribute table for
255 inconsistencies.
256 - New -v flag for the version command (print verbose version string)
257 - New option --priority for para_server and para_audiod.
258 - New mood methods: image_id and lyrics_id.
259 - The manual and this NEWS file have been converted to markdown.
260 - Support for the compile-time loglevel feature has been removed.
261 - Cleanup of the wma decoder and bitstream code.
262 - Improved wide-character support and fixes related to signal handling.
263 - para_gui no longer reports 100% playing time at the stream start.
264 - Opus cleanups.

271 0.5.5 (2015-09-20) "magnetic momentum"
272 --------------------------------------
273
274 Many new features and a lot of other improvements.
275
276 - On Linux systems, local sockets are now created in the
277 abstract name space by default. This allows to get rid of
278 the socket specials in /var/paraslash.
279 - The --user-allow option of para_audiod now accepts also
280 usernames rather than only user IDs.
281 - New autoconf macros to avoid duplication in configure.ac.
282 - Status items (as shown by para_gui) are updated correctly
283 when the meta information of the current audio changes.
284 - para_server and para_audiod no longer refuse to start in
285 the background if no log file is given. Instead, all log
286 messages go to /dev/null in this case.
287 - Web page cleanup.
288 - New syntax for the -l and -s options of the ls command.
289 These options should now be specified as -l=v rather than
290 -lv, for example. The old syntax still works, but support
291 will be dropped in v0.6.0.

319 0.5.3 (2014-08-01) "symbolic synchronization"
320 ---------------------------------------------
321
322 Not many new features, but lots of fixes and usability improvements.
323
324 - para_gui has been converted to use the paraslash scheduler.
325 - Various alsa-related fixes, mostly for the raspberry pi.
326 - Many scheduler improvements and cleanups.
327 - The test suite has been extended to include sanity checks
328 for the generated man pages.
329 - ao_writer fixes. This writer was in a quite bad shape. Many
330 serious bugs have been fixed.
331 - new audiod command: version.
332 - Minor improvements to the bitstream API.
333 - The cpsi command now prints a meaningful error message if
334 none of the given patterns matched any audio file.

341 0.5.2 (2014-04-11) "orthogonal interior"
342 ----------------------------------------
343
344 The new sync filter, the AES_CTR128 stream cipher and the overhauled
345 network code are the highlights of this release. It also includes a
346 fair number of smaller fixes and improvements not mentioned here.
347
348 - The new sync filter synchronizes playback between multiple
349 clients.
350 - Connections between para_server and para_client are now
351 encrypted by means of AES rather than RC4 if both sides
352 support it. RC4 is still available as a fallback. This
353 feature is fully transparent, i.e. no command line options
354 are necessary, and a client linked against openssl can
355 speak with a server linked against libgcrypt and vice versa.
356 - Major cleanup of the networking subsystem.
357 - Improvements to para_fade: the new set mode, multi-channel
358 initial volumes, better error logging.
359 - The man pages of para_audiod, para_filter, para_recv, and
360 para_write contain the relevant options for receivers, filters,
361 writers. This broke in 0.5.0.
362 - ogg/vorbis latency improvements.
363 - Improved user manual.
364 - Minor fixes to avoid clang warnings.

371 0.5.1 (2013-12-20) "temporary implication"
372 ------------------------------------------
373
374 Lots of fixes and improvements all over the place, and a major overhaul
375 of the build system.
376
377 - Audiod improvements and fixes.
378 - Buffer tree robustness improvements.
379 - Cleanup of the mood subsystem.
380 - Fixes and cleanups for the flac decoder.
381 - Latency improvements for the ogg/opus decoder.
382 - Crypto support is now optional. On systems without
383 openssl/gcrypt, the build succeeds but para_server,
384 para_audiod, para_client won't be built.
385 - The build system now works for cross-compile setups.
386 - The dependency tree has been flattened, which speeds up
387 builds and avoids to recreate the man pages on every change.
388 - The error code helper has been rewritten from perl to C,
389 which further improves build time.
390 - Many small bugs in the build system have been identified
391 and fixed.

398 0.5.0 (2013-08-23) "invertible validity"
399 ----------------------------------------
400
401 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
402
403 - The sideband compatibility code has been removed, hence
404 sideband connections (introduced in 0.4.11) are now mandatory.
405 - Addblob commands can produce output.
406 - The stat command no longer sends garbage when para_server was
407 compiled against libgcrypt.
408 - Dependencies for gengetopt files are computed automatically.
409 This eliminates a constant source of build bugs.
410 - The setatt command now accepts file name patterns rather than only
411 path names.
412 - overview.pdf is now based on dia, a simple diagram creation program.
413 The new version is much more detailed and contains descriptions of
414 the various programs of the paraslash package.
415 - The separator of all multi-word options has been changed from
416 underscore to dash. For example --log_color becomes --log-color.
417 - Overhauled web pages and the new logo.

424 0.4.13 (2013-07-29) "spectral gravity"
425 --------------------------------------
426
427 One more 0.4.x release before the API-breaking changes for 0.5.0 go
428 in. The main features of this release are the ogg/opus audio format,
429 and UTF-8 support, but it includes also tons of other improvements
430 and fixes all over the place.
431
432 - New audio format: ogg/opus.
433 - UTF8 support for para_gui and the mp3 audio format handler.
434 - Scheduler improvements and fixes.
435 - The obsolete gettimeofday() function has been replaced
436 by clock_gettime() on systems which support it.
437 - Speed and usability improvements for para_gui.
438 - para_client now restores the fd flags of stdin and stdout
439 on shutdown.
440 - Improved manual pages.
441 - Consistent version strings for all executables.
442 - Reduced dependencies on generated files result in fewer
443 recompilations on changes.
444 - Performance improvements for the compress filter.
445 - Improved downloads web page.
446
447 -----------------------------------------
448 0.4.12 (2012-12-20) "volatile relativity"
449 -----------------------------------------
450 The new command line player, the resample filter, ALSA support for
451 para_fade, and the improved build system are the highlights of this
452 release which probably marks the end of the 0.4.x series.
453
454 - The afh receiver and the para_play executable.
455 - The resample filter: A sample rate converter based on
456 libsamplerate.
457 - The "versions" directory has been removed from the master
458 branch. The tarballs of the old releases are now available
459 in the new "releases" branch.
460 - Overhaul of the build system: All generated files are now
461 written to the "build" directory.
462 - The modular mixer API and the alsa mixer.
463 - Minor fixes for the osx writer.
464
465 --------------------------------------
466 0.4.11 (2012-07-20) "mutual diversity"
467 --------------------------------------
468
469 The major feature in this release is the new sideband API for
470 client-server communication. This API will be used exclusively starting
471 with 0.5.0, which breaks backward compatibility but allows to get rid
472 of quite some compatibility code. Other noteworthy changes include
473 decoder latency improvements and a long-standing bug fix for the
474 ALSA writer.
475
476 - Sideband connections: If both para_server and para_client
477 support this feature, data is sent as a multiplexed stream.
478 - The --no_default_filters option of para_filter has been
479 removed.
480 - Several fixes and latency improvements to various decoders.
481 - The ALSA writer now limits the prebuffer time to 500ms.
482 - Documentation improvements.
483 - Overhaul of the command_util.sh script.
484 - Fixes for some minor problems found by the clang analyzer.
485 - Compiles (almost) without warnings on gcc-3.
486 - Robustness improvements of the buffer tree code.
487
488 ------------------------------------------
489 0.4.10 (2012-03-30) "heterogeneous vacuum"
490 ------------------------------------------
491
492 Nothing earth-shaking in this release, but quite a few usability
493 improvements and the usual mix of cleanups and fixes.
494
495 - The --no_default_filters option of para_filter has been
496 deprecated. It still works but has no effect and will be
497 removed in the next version.
498 - para_gui now prints also the stderr output of the executing
499 command in the bottom window.
500 - Cleanup and consolidation of the various wrappers for
501 write(), writev(), send() and friends.
502 - The obscure error messages on mmap() failures have been
503 replaced by meaningful messages. This affects mainly
504 para_afh.
505 - para_audioc: Cleanups and memory leak fixes.
506 - Test 0004-server no longer fails if para_server is not
507 being built.
508 - New configure options: --with-id3tag-{headers,libs}.
509
510 -------------------------------------
511 0.4.9 (2011-12-06) "hybrid causality"
512 -------------------------------------
513
514 Support for another audio format, interactive mode for para_client
515 and para_audiod and many small improvements/fixes all over the place.
516
517 - Support for flac, the free lossless audio codec.
518 - Fix for an endless loop in the mp3 decoder for certain
519 (corrupt) mp3 files.
520 - When executed without specifying a command, para_client
521 and para_audioc start an interactive shell (requires
522 libreadline being installed). The interactive mode offers
523 full tab completion and command line history.
524 - autogen.sh now detects a distcc setup and adjusts the
525 parameter for the -j option of make accordingly.
526 - Shared memory areas are no longer restricted to 64K. We now
527 detect the maximal size of a shared memory area at runtime.
528 - cleanup of the internal uptime API.
529 - para_server prefaults the mmapped audio file to avoid
530 delays on slow media.
531 - A new test for the test-suite that exercises the
532 communication between para_server and para_audiod.
533 - The alsa writer eats up less CPU cycles when configured to
534 use the DMIX plugin.
535 - Simplified and unified receiver code.
536 - Makefile cleanups.
537 - Commands which print a list of matching audio files now
538 emit a meaningful error message if no audio file matched the
539 given pattern(s).
540
541 --------------------------------------
542 0.4.8 (2011-08-19) "nested assignment"
543 --------------------------------------
544
545 Gcrypt support, the overhauled osx writer and regex format specifiers
546 are the highlights of this release.
547
548 - support for libgcrypt as a drop-in replacement for openssl.
549 Run configure --enable-cryptolib=gcrypt to link against
550 libgcrypt. The two crypto implementations are compatible to
551 each other, i.e. a para_client executable linked against
552 gcrypt can connect to para_server linked against libssl
553 and vice versa.
554 - Rewrite of the osx writer (output plugin for Mac OS).
555 - audiod: The format specifier for receivers, filters and
556 writers is now treated as a regular expression. This allows
557 to replace 5 lines in the config file (one for each audio
558 format) by one single line. See the manual for details.
559 - The \*.cmdline.[ch] files are no longer contained in the released
560 tarballs. This reduces the size of the tarballs but requires
561 gengetopt to build the tarball.
562 - Compiles cleanly also with llvm/clang.
563 - Corrupt mp3 files are handled more gracefully.
564 - The alsa writer uses poll fds instead of computing timeouts.
565 - Cleanup of the generic writer API.
566 - sched: Optimized zero timeouts.
567 - vss timeout cleanups.
568 - oggdec fixes and improvements.
569
570 --------------------------------------
571 0.4.7 (2011-06-01) "infinite rollback"
572 --------------------------------------
573
574 The new ao writer, support for ssh RSA keys and a couple of other
575 enhancements.
576
577 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
578 platforms through the libao audio library.
579 - Support for RSA keys generated with ssh-keygen.
580 - configure: improved options for ogg/vorbis/speex.
581 - The git version reported by --version always matches HEAD.
582 - The autogen script detects the number of processors and
583 runs a parallel make if possible.
584 - Major cleanup of the crypto API.
585 - Documentation updates.
586
587 ------------------------------------------
588 0.4.6 (2011-03-31) "deterministic entropy"
589 ------------------------------------------
590
591 Lots of ogg/vorbis improvements, the new test suite, enhancements
592 for para_gui and a fair amount of other bug fixes.
593
594 - For DCCP/OGG streams the audio file header is only sent once
595 at the beginning of the stream rather than periodically
596 every five seconds. This reduces network traffic and the
597 FEC group size.
598 - The vorbis comment header is replaced by an empty dummy header
599 before the header is sent over the network. This also results in
600 less network traffic and smaller FEC groups.
601 - The new "test" make target allows to perform some sanity checks prior
602 to installing the package.
603 - ogg timing fixes and performance improvements
604 - Scheduler improvements
605 - Proper exit codes for para_write
606 - para_gui: New option --theme to select a startup theme. Several
607 other improvements and fixes.
608 - aacdec error message cleanups
609 - simplified color error handling
610
611 --------------------------------------------
612 0.4.5 (2010-12-17) "symmetric randomization"
613 --------------------------------------------
614
615 Bug fixes, internal cleanups and variable-sized FEC slices.
616
617 - Contains a fix for an invalid-free-bug in the ogg audio format
618 handler code.
619 - Switching off the DCCP sender works again.
620 - para_audiod handles crashes of para_server more robustly.
621 - Internal scheduler and writer cleanups.
622 - Reduced latency due to variable-sized FEC slices.
623 - Improved documentation and error diagnostics.
624 - The build of para_server is now optional, allowing the build
625 to succeed in case libosl is not installed.
626
627 ------------------------------------------
628 0.4.4 (2010-08-06) "persistent regularity"
629 ------------------------------------------
630
631 Support for yet another audio format, para_write improvements and
632 bug fixes.
633
634 - Support for the speex codec.
635 - Support for sample formats other than 16 bit little endian.
636 - error2.h is now created by a perl script which speeds up configure
637 considerably.
638 - Fix a bug in the aac decoder which could lead to segfaults in
639 para_filter/para_audiod.
640 - Fixes for autoconf-2.66.
641
642 ----------------------------------------
643 0.4.3 (2010-07-05) "imaginary radiation"
644 ----------------------------------------
645
646 Many improvements for the DCCP and the UDP transport, the new user
647 manual and the usual mix of bug fixes and internal improvements.
648
649 - FEC support for the DCCP sender (Gerrit Renker). The new
650 --dccp_max_slice_size, --dccp_data_slices_per_group and
651 --dccp_slices_per_group options can be used to set the FEC
652 parameters for the DCCP transport.
653 - DNS lookups for UDP targets (Gerrit Renker).
654 - The new user manual replaces the README, README.afs, REQUIREMENTS
655 and INSTALL documents.
656 - Fix an end-of-file detection bug in the oggdec filter.
657 - The new nonblock API.
658 - Both options of the oggdec filter have been removed.
659 - New debug mode for the internal scheduler.
660
661 ------------------------------------------
662 0.4.2 (2010-04-23) "associative expansion"
663 ------------------------------------------
664
665 It's been some time since the last release, but finally here is
666 paraslash-0.4.2. The bulk of the changes comes from the new buffer
667 tree API, but there are changes all over the tree. Mainly performance
668 and usability improvements, but also quite some bug fixes.
669
670 - The new buffer tree API.
671 - DCCP: Support for CCID negotiation (Gerrit Renker).
672 - UDP robustness fixes.
673 - The --bufsize option for mp3dec is gone as it no longer makes sense
674 for the new buffer tree API.
675 - Fix audible buffer underruns for wma streams.
676 - The alsa writer no longer prints meaningless underrun durations.
677 - audiod: Defaults work also for udp streams. If no filter is
678 given for an audio format that is received via upd, fecdec is
679 automatically added as the first filter (along with the decoder).
680
681 ---------------------------------------
682 0.4.1 (2009-12-22) "concurrent horizon"
683 ---------------------------------------
684
685 Support for another audio format, minor feature enhancements and lots of bug
686 fixes. All fixes that have been accumulated in the maint branch (in particular
687 those mentionened in the 0.3.6 release notes) appear in this release as well.
688
689 - wma support.
690 - new afh option: --human to activate human-readable output.
691 - new server/audiod option: --log-timing to print timing information.
692 - build system improvements.
693 - source code documentation updates.
694
695 -------------------------------------
696 0.3.6 (2009-12-07) "cubic continuity"
697 -------------------------------------
698
699 Quite a few bugs have been found and fixed since 0.3.5, so here's
700 another 0.3.x release. No new features.
701
702 - Always check return value of malloc().
703 - ogg vorbis/FEC: Do not write garbage after the audio file header.
704 - exit if root privileges could not be dropped.
705 - FEC: Fix computation of extra slices.
706 - oss: Fix check for empty input buffer.
707 - Avoid buffer underruns due to filter chain output buffer constraints.
708 - server: Fix assignment of afs_pid.
709 - Don't panic if the afs database contains unknown audio formats.
710 - http/dccp: Do not send the audio file header twice.
711 - FEC: Timing improvements.
712
713 ----------------------------------------------
714 0.4.0 (2009-11-10) "simultaneous independence"
715 ----------------------------------------------
716
717 Two significant changes which require the new version number: The
718 improved authentication dialog and the fact that the database code
719 has been moved to a library, libosl. To use the new version, you have
720 to generate new RSA keys, see INSTALL for details. A shell script is
721 provided for conversion of the 0.3 database to the new 0.4 format.
722
723 - stronger crypto for client authentication
724 - the database code has been moved to a library
725 - improved status item handling
726 - cleanup of the build system
727 - The "-V" option now also prints the git version
728 - the new parser-friendly listing mode for the ls and stat commands
729 - mandatory rc4 encryption
730 - major audio format handler cleanups
731 - (id3,...) tags are no longer stored as a combined string in the database
732 - new mood methods: artist_matches, title_matches, comment_matches,
733 album_matches, year_maches, year.
734
735 --------------------------------------------
736 0.3.5 (2009-09-21) "symplectic separability"
737 --------------------------------------------
738
739 Full client support for \*BSD Unixes, complete re-write of the ogg
740 vorbis audio format handler, various improvements all over the place
741 and the usual mix of bugfixes. This release marks the end of the 0.3
742 series if no serious problems show up.
743
744 - the new oss writer (supported on \*BSD and Linux)
745 - rewrite of the ogg vorbis audio format handler. It's
746 recommended to replace the chunk tables of existing ogg
747 vorbis files in the afs database by re-adding these files
748 with "add -f".
749 - support for netmask subsets (Gerrit Renker)
750 - the new prebuffer filter
751 - improved signal handling
752 - variable fec output buffer size
753 - improved FEC timing fixes audible buffer underruns in UDP mode
754 - --log_color actually works
755 - new ls option: -d (print dates as seconds after the epoch)
756 - update to gengetopt 2.22.2
757 - support for RSA keys of size > 512 bits
758 - new option "mixer_channel" for para_fade
759
760 -----------------------------------------
761 0.3.4 (2009-05-07) "elliptic inheritance"
762 -----------------------------------------
763
764 The new udp sender, forward error correction, colored logs and various
765 other improvements. As the udp sender does not depend on any special
766 libraries, it is built unconditionally.
767
768 - The udp sender replaces the ortp sender. The new code uses forward
769 error correction to protect against packet losses. Many thanks to
770 Gerrit Renker for providing ipv6 support.
771 - The default port for udp streaming now defaults to 8000, like
772 for the http and the dccp senders/receivers.
773 - Loglevels are now specified as symbolic names, e.g.
774 "--loglevel info".
775 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
776 - para_server/para_audiod: Color support for log messages.
777 - new options for mp3dec: --ignore-crc, --bufsize
778 - new audiod option: --config-file.
779 - gengetopt cleanups.
780 - Improved help/man pages: The documentation of para_audiod,
781 para_recv, para_filter and para_write now also contains
782 all options of the available receivers/filters/writers. The
783 man page of para_fade contains a description of the different
784 modes of operation.
785 - More source code documentation.
786 - vss timing fixes.
787
788 --------------------------------------------
789 0.3.3 (2008-12-01) "axiomatic perspectivity"
790 --------------------------------------------
791
792 Internal code cleanups, bug fixes, improved tag handling and the new
793 amplification filter.
794
795 - para_server uses the generic scheduling code.
796 - overhaul of the virtual streaming system.
797 - mp3: id3 version 2 support via libid3tag (optional)
798 - ogg: vorbis comment support.
799 - aac meta info support.
800 - mp3 audio format handler cleanups.
801 - new filter: "amp" to amplify the amplitude of the audio stream
802 - new status item/database entry: amplification. It is
803 used by the amp filter to pre-amplify the audio stream.
804 - fix a close-without-open bug in para_write.
805 - fix a bug in com_init() which was introduced in 0.3.2.
806 - better error diagnostics for para_client.
807
808 -----------------------------------------
809 0.3.2 (2008-04-11) "probabilistic parity"
810 -----------------------------------------
811
812 The new para_afh executable, scheduling and documentation improvements.
813
814 - new ls option: -lc (list chunk table)
815 - new executable: para_afh, the stand-alone audio file handler tool
816 - afs commands can send output more than SHMMAX (32MB on Linux). This
817 also reduces the memory usage of commands that produce large amounts
818 of output.
819 - major scheduler and audiod cleanups.
820 - more detailed and much nicer man pages.
821
822 ---------------------------------------
823 0.3.1 (2008-02-23) "liquid interaction"
824 ---------------------------------------
825
826 A mix of cleanups, bug fixes, improvements, and some new features. No
827 significant changes to the new database (osl) code, which is generally
828 a good sign.
829
830 - Share some similar/duplicate code between the http and the
831 dccp sender.
832 - Generic access control lists for paraslash senders.
833 - dccp sender: Access control lists, connection limiting and support
834 for the allow,deny,on,off,help sender commands.
835 - The default dccp port changed from 5001 to 8000 (suggested by
836 Gerrit Renker).
837 - para_server starts even if not all public keys could be loaded.
838 - Audiod performance improvements.
839 - fix a bug in the "off" command of the http sender.
840 - fix some fd and memory leaks.
841 - Update to gengetopt-2.22.
842
843 -------------------------------------
844 0.3.0 (2008-01-12) "solar saturation"
845 -------------------------------------
846
847 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
848
849
850 Usually one might expect lots of new features AND a big increase in size
851 for a major release like this.
852
853 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
854 ever. The decrease in size is mostly due to the removal of some
855 graphical tools (which were only quick hacks anyway). But also the
856 fact that the mysql code is gone cuts down the size a bit.
857
858 Being independent of mysql comes at a cost: The fact that paraslash
859 now contains its own database (the object storage layer, osl) increases
860 the (stripped) binary size of para_server by ~50K on i386.
861
862 - no more restrictions on unique basenames.
863 - independent of mysql: The new self-contained object
864 storage layer (osl) replaces the mysql database.
865 - New executable para_fsck: Check integrity of osl tables.
866 - Lyrics support.
867 - Reliable audio file move/rename detection.
868 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
869 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
870 Solaris (sparc64).
871 - the new osl-based audio file selector (afs) replaces the random,
872 the playlist and the mysql selector of paraslash-0.2.x.
873 - IPv6 support (thanks to Gerrit Renker).
874 - paraslash-0.2.x streams are now called "moods". Writing
875 0.3.x-mood definitions should be both easier and more
876 powerful than writing 0.2.x-stream definitions.
877 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
878 been removed. The world is a better place without them. However,
879 para_gui is still there.
880 - afs tracks audio file selection also in playlist mode.
881 - few easy-to-use afs commands replace the many not-so-easy-to-use
882 mysql commands (and are available also in playlist mode).
883 - Improved error subsystem.
884 - The earth-shaking new logo.
885
886 -----------------------------------------
887 0.2.17 (2007-11-20) "isotropic threshold"
888 -----------------------------------------
889
890 Mainly bugfixes and cleanups in this version which marks the end of
891 the 0.2.x series if no serious bugs show up after the release.
892
893 - mysql_selector: fix a locking bug.
894 - universal chunk queueing.
895 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
896 to Gerrit Renker).
897 - be more carful wrt. signed vs. unsigned argument passing.
898 - cleanup error.h and fix some references to invalid error
899 codes.
900 - update to gengetopt-2.21.
901 - update to ortp-0.13.1.
902 - autoconf: extend checks for headers, library functions and
903 compiler characteristics.
904 - Fix streaming of large mp3 files.
905 - Fix an off-by-one bug in playlist handling.
906
907 --------------------------------------
908 0.2.16 (2007-04-05) "neural discharge"
909 --------------------------------------
910
911 The main change in this release is the major audio format handler
912 cleanup which removes some similar/duplicate code and makes it easier
913 to implement plugins for other audio formats. Of course, the usual mix
914 of other improvements/changes/bugfixes also made it into the release.
915
916 - simplified audio format handlers (most of the handling functions
917 were moved one layer up to the virtual streaming system).
918 - para_server uses mmap to read audio files
919 - repositioning of mp3 streams is much faster, in particular for
920 jumping near the end of large mp3 files.
921 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
922 and AFS_WRITE.
923 - fix a bug in para_filter that caused decoding of aac files
924 to start only after a few seconds.
925 - fix osx_writer hangs
926 - simplified dccp code (thanks to Gerrit Renker)
927 - the compress filter works also on big endian systems (ppc)
928
929 -----------------------------------------
930 0.2.15 (2007-02-16) "inductive resonance"
931 -----------------------------------------
932
933 Minor improvements, more documentation and a bunch of bug fixes.
934
935 - para_server: The server.users file is only read once on server
936 startup rather than for each connection
937 - mp3dec: Fix decoding of corrupt mp3 files
938 - afs (audio file sender) is now called vss (virtual streaming
939 system). Consequently, the permission flags specified in
940 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
941 become VSS_READ and VSS_WRITE respectively.
942 - para_audiod/para_filter: Fix a bug that caused the last chunk
943 of audio data not being written under certain circumstances
944 - audiod: compute the difference of server time and local time
945 correctly
946 - para_server/para_audiod: Fix some memory leaks
947 - documentation improvements
948 - configure.ac: fix checks for para_krell
949 - new man pages
950
951 -------------------------------------------
952 0.2.14 (2006-10-15) "transient singularity"
953 -------------------------------------------
954
955 The only major enhancement of this version is the osx writer which completes
956 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
957 until now for reasons beyond the scope of this changelog entry.
958
959 - new output plugin for Mac Os: the osx writer
960 - rename configure command line options from --enable-xxx-headers to
961 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
962 - configure: new command line options: --with-mad-headers,
963 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
964 - some robustness fixes
965 - dymamic audio format recognition for audiod
966 - para_server: new command line option: --autoplay_delay
967 - para_audiod: new command line option: --clock_diff_count
968
969 ---------------------------------------
970 0.2.13 (2006-07-14) "sonic convolution"
971 ---------------------------------------
972
973 A bunch of new features and core changes.
974
975 - the new paraslash scheduler, short and sweet.
976 - Support for m4a/mp4 files via the new aac audio format
977 handler/filter (requires libfaad).
978 - each writer has its own command line parser, just like
979 para_recv and para_filter.
980 - para_client and para_audioc use the error subsystem
981 - writers are integrated in para_audiod (currently linux-only)
982 - para_client is integrated in para_audiod
983 - random/playlist selector: improved info strings
984 - new audiod commands: tasks, kill
985 - update to libortp-0.10.1
986 - para_fade: wake time defaults to 8 hours from now
987 - update to autoconf-2.60
988
989 ------------------------------------------
990 0.2.12 (2006-05-12) "oriented abstraction"
991 ------------------------------------------
992
993 Many user-visible changes in this release and lots of new
994 features:
995
996 - the new optional dccp sender/receiver. It uses the datagram
997 congestion control protocol. You'll need a fairly new kernel
998 for this.
999 - paraslash works on Mac OS X (thanks to Gerd Becker)
1000 - para_play renamed to para_write
1001 - modular output plugin design (writers) for para_write
1002 - new file_writer output plugin for para_write
1003 - compress filter speed improvements
1004 - update to libortp-0.9.1
1005 - update to gengetopt-2.17rc
1006 - para_client no longer depends on libreadline (as the
1007 code for the interactive mode was removed).
1008 - gcc-2-95 is no longer a supported compiler. It may still
1009 work, but it gets no more testing.
1010 - the tarball no longer contains the screenshot images which
1011 reduces its size quite a bit.
1012 - configure: new command line options: --enable-mysql-headers
1013 and --enable-mysql-libs
1014
1015 ------------------------------------
1016 0.2.11 (2006-03-11) "atomic duality"
1017 ------------------------------------
1018
1019 Here it is, the first paraslash release developed with git. There
1020 are fairly many user-visible changes in this release. As two out of
1021 the three "database tools" of paraslash don't use a database at all,
1022 they are now called "audio file selectors" instead.
1023
1024 - the cdt command (change database tool) becomes chs (change
1025 selector)
1026 - no more colon separators: The syntax of some options of
1027 para_audiod and para_filter have changed. Use --help for
1028 more info (and some examples).
1029 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
1030 - switch from cvs to git (should've done that earlier)
1031 - the new ipc subsystem
1032 - new audio file selector: playlist
1033 - para_server: the dopey selector is now called "random",
1034 and is the default selector. Use the --selector option to
1035 choose another selector at startup, or the chs command to
1036 change the selector at runtime.
1037 - X86_64 fixes (thanks to Steffen Klassert)
1038 - para_play fixes
1039
1040 --------------------------------------
1041 0.2.10 (2006-02-17) "cyclic attractor"
1042 --------------------------------------
1043
1044 Huge documentation update, a scrollable window for para_gui, ortp
1045 improvements, and of course many small fixes not mentioned here.
1046 The diffstat below is rather misleading as most insertions are due
1047 to the new source documentation.
1048
1049 - autoconf cleanup
1050 - para_server also uses the new error subsystem
1051 - lots of new documentation (UTSL)
1052 - gui improvements:
1053 - keysyms for cursor keys and for next/previous page keys
1054 - scrollable output window
1055 - new internal commands: scroll up/down, page up/down
1056 - fix color of command output.
1057 - ortp: the --chunk_time and --header flags are no longer needed
1058 for para_recv/para_audiod as this information is now encoded in
1059 each rtp packet sent by para_server.
1060
1061 -------------------------------------------
1062 0.2.9 (2006-01-24) "progressive turbulence"
1063 -------------------------------------------
1064
1065 Internal audiod receivers/filters, the new error subsystem and
1066 a lot of small improvements.
1067
1068 - para_recv and para_filter are integrated into the para_audiod
1069 binary, i.e. audiod no longer spawns a new process for
1070 each receiver/filter. As para_recv and para_filter might be
1071 useful as standalone programs, they still get built (linked
1072 against the same object files that are also used for audiod).
1073 - further ortp timing improvements should reduce the CPU usage
1074 of the ortp receiver.
1075 - improved audio grabbing. The 'grab' command of para_audiod
1076 has its own set of command line options. Read the output of
1077 "para_audioc help grab" for more info.
1078 - oggdec: configurable input prebuffer size.
1079 - the new error subsystem gives better error diagnostics
1080 and reduces code size.
1081
1082 -----------------------------------------
1083 0.2.8 (2006-01-02) "dynamic accumulation"
1084 -----------------------------------------
1085
1086 The new modular filter design and the para_play-hangs bugfix.
1087
1088 - new executable: para_filter. It combines para_mp3dec,
1089 para_oggdec and para_compress. It also adds a further filter
1090 type, wav, that just inserts a wave header at the desired point
1091 of the filter chain. All 'piping' is done in-memory (i.e. no
1092 read/write operations are used).
1093 - para_play: fix a stupid bug that caused it to hang under
1094 certain circumstances.
1095
1096 -------------------------------------------
1097 0.2.7 (2006-12-27) "transparent invariance"
1098 -------------------------------------------
1099
1100 Not many user-visible changes but a fair amount of internal improvements.
1101
1102 - The http sender buffers data if it can not be sent
1103 out immediately (because the socket is not writable). This
1104 should prevent para_server from shutting down the connection
1105 too early on a loaded network.
1106 - para_play also prebuffers data if it is told to start at a
1107 future time by the --start_time option.
1108 - The return of para_recv: It combines para_ortp_recv and
1109 para_http_recv. Use the --receiver option to switch between
1110 the two. para_recv builds without libortp, but contains
1111 only the http receiver in this case.
1112 - update to ortp 0.8.1. As this ortp release contains incompatible
1113 changes, para_recv-0.2.7 won't link against older ortp libs.
1114 - improved ortp timings.
1115 - use of gcc-extensions that #define away for non-gcc and
1116 gcc < 3.0.
1117
1118 -------------------------------------------
1119 0.2.6 (2005-10-29) "recursive compensation"
1120 -------------------------------------------
1121
1122 Transparent session encryption (uses openssl's Alleged RC4 cipher),
1123 the internal find command and several other improvements and cleanups.
1124
1125 - Encrypt the session if encryption is requested by the client
1126 (default for para_client 0.2.6). This is backwards
1127 compatible, so older clients can still connect to para_server
1128 0.2.6. Use the new client option --plain to request an
1129 uncrypted session (off by default, must be set to on in
1130 order to connect to para_server 0.2.x with 0 <= x <= 5).
1131 - para_server uses an internal function to locate audio files
1132 rather than calling find(1). The server option
1133 --mysql_audio_file_dir replaces --mysql_find_cmd.
1134 - documentation update
1135 - man pages
1136 - header file cleanup
1137 - para_client code cleanup
1138 - para_gui: faster display of output of display commands
1139
1140 ------------------------------------------
1141 0.2.5 (2005-10-13) "aggressive resolution"
1142 ------------------------------------------
1143
1144 This release adds internal senders, i.e. no more external programs are
1145 spawned for sending out the audio data. There are two different senders
1146 available: The http sender and the ortp sender (former para_send which
1147 is no longer needed).
1148
1149 The new sender code has a plugin-like design so it can be easily
1150 extended should there be be any future need for supporting another
1151 network streaming protocol. All senders are completely independent of
1152 each other. In particular, the http and the ortp sender can operate
1153 in parallel.
1154
1155 - new server command: sender to control senders at runtime.
1156 Read the output of "para_server -h" and "para_client help
1157 sender" for more information.
1158 - para_recv renamed to para_ortp_recv
1159 - new executable: para_http_recv, a simple command line
1160 http receiver.
1161 - major afs/mp3/ogg code simplifications due to internal
1162 senders.
1163 - ogg timing improvements
1164 - fix several minor memory leaks (found by valgrind)
1165 - empty stream definitions work again
1166 - com_ne(): ignore errors on remove
1167 - audiod: fix segfault on server restart
1168
1169 ---------------------------------------
1170 0.2.4 (2005-09-21) "toxic anticipation"
1171 ---------------------------------------
1172
1173 Several small improvements, fixes and the new grab command.
1174
1175 - audiod:
1176 - new command: "grab" to grab the output of the stream reader
1177 or any filters. Read the output of "para_audioc help grab"
1178 for more information.
1179 - fix memory leak
1180 - code cleanup
1181 - audioc: new command line option: --bufsize to specify a
1182 buffer size different from the default size 8192.
1183 - improved error diagnostics for para_play.
1184 - new configure option: --enable-ssldir so search for openssl in
1185 non-standard places
1186 - sdl_gui: Make it look nice again for 1024x768
1187 - server: report total size of memory allocated with sbrk by malloc,
1188 new command line option: --announce_time
1189
1190 -----------------------------------------
1191 0.2.3 (2005-09-01) "hydrophilic movement"
1192 -----------------------------------------
1193
1194 Two new executables and major feature enhancements.
1195
1196 - audiod filters: It is now possible to specify arbitrary many
1197 (including none) filters for each supported audio
1198 format. This can be used e.g. for normalizing volume,
1199 transforming or grabbing the audio stream, or for using
1200 visualizers. Read the output of "para_audiod -h" for the
1201 syntax of the new --filter_cmd option.
1202 - new executable: para_play, a tiny alsa player. It
1203 can play wave files or raw pcm (16 bit little endian)
1204 from stdin.
1205 - new executable: para_compress, a dynamic range compressor
1206 intended to keep audio output at a consistent volume. Derived
1207 from [AudioCompress](http://trikuare.cx/code/AudioCompress.html).
1208 - audiod: New option: --stream_delay. This can be used in
1209 a local network to syncronize the audio output of all
1210 clients that play the same stream.
1211
1212 ------------------------------------------
1213 0.2.2 (2005-08-19) "tangential excitation"
1214 ------------------------------------------
1215
1216 Mostly internal changes in this release, but also some new commands
1217 for the mysql database tool.
1218
1219 - cleanup exec.c, fix para_exec bug
1220 - compile time loglevel (log messages below the given level
1221 won't be compiled in, which reduces the size of the
1222 resulting binaries)
1223 - new log macros that shorten the size of the source code.
1224 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
1225 to send only zeros. With this workaround, para_audioc works
1226 again.
1227 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
1228 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
1229 (new entry), "snp" (set numplayed). Read the manual for more
1230 information.
1231
1232 ---------------------------------------
1233 0.2.1 (2005-08-15) "surreal experience"
1234 ---------------------------------------
1235
1236 Here comes paraslash-0.2.1. It contains a couple of new features and,
1237 surprise, only minor bug fixes.
1238
1239 - kill noisy mp3 debug message
1240 - cleanup of the build system
1241 - para_server and para_client directly use the crypto routines
1242 of the openssl library rather than invoking the openssl command
1243 line utitlity
1244 - server/audiod: new option --user to switch to the given user
1245 when invoked as root. Read the output of "para_server -h" for
1246 more information.
1247 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
1248 status. Default: "para_audioc stat"
1249 - sdl_gui: new option --pic_cmd to be used to download the picture.
1250 Default: "para_client pic"
1251 - audiod: 5 slots ought to be enough for everybody
1252 - audiod: new status item: Uptime, kill hup command
1253
1254 ------------------------------------------
1255 0.2.0 (2005-08-06) "distributed diffusion"
1256 ------------------------------------------
1257
1258 After several month of increased development activity, paraslash-0.2.0
1259 has arrived. It contains many new features and is much more
1260 self-contained than the old 0.1.x series. Enjoy!
1261
1262 - para_server: fix hang on song change and crash on sighup.
1263 Speed up mysql queries. The DIR_LIKE macro is gone.
1264 - new executables: para_audiod, the local audio daemon that
1265 starts playback (uses SCM_CREDENTIALS socket magic) and
1266 para_audioc, the corresponding client.
1267 - new executables: para_mp3dec/para_oggdec, two really teensy
1268 decoders. para_mp3dec is based on libmad, para_oggdec requires
1269 libvorbisfile.
1270 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
1271 they are now called para_send and para_recv respectively.
1272 - documentation updates
1273 - para_gui is themable. For now there is the default theme that
1274 looks as before and the simple theme: blue and easy.
1275 - gui: audio streaming is now handled by audiod. Time display shows
1276 playback time rather than streaming time
1277 - slider: update to libzmw-0.2.0
1278 - para_krell: fix crash on server shutdown
1279 - switch from gzip to bzip2
1280
1281 ----------------------------------------
1282 0.1.7 (2005-04-18) "melting penetration"
1283 ----------------------------------------
1284
1285 The main change in this release is clearly the oggvorbis rewrite,
1286 but there are also lots of smaller changes. If you intend to use both
1287 the mp3 and the ogg plugin, it is recommended to use software mixing,
1288 e.g. the dmix plugin which is provided by ALSA.
1289
1290 - new executables: para_ovsend and para_ovrecv for sending/receiving
1291 oggvorbis files via rtp. Requires the open rtp library. Get it at
1292 http://www.linphone.org/ortp/
1293 - rewrite of the ogg_vorbis core code
1294 - configure detects libzmw and, if detected, includes
1295 para_slider to the list of binaries to be built by make
1296 - server stream writers read from their associated fifo rather
1297 than from stdin
1298 - slider: two new sliders, lastplayed and numplayed
1299 - fix nasty double free bug which caused random segfaults in case of
1300 mp3 files with invalid header information
1301 - gui: new command line option: --stream_timeout=seconds to
1302 deactivate a slot if it is idle for that many seconds (default=`5')
1303 - diffstats
1304
1305 ---------------------------------------
1306 0.1.6 (2005-03-05) "asymptotic balance"
1307 ---------------------------------------
1308
1309 Only little user-visible changes in this release. Mainly bugfixes and
1310 core code cleanup. This is probably the most stable version ever if you
1311 stick to mp3...
1312
1313 - fix several memory leaks
1314 - rename default name of mysql database from "music" to "paraslash".
1315 Use para_server's --mysql_database option if you do not want to
1316 rename your old database.
1317 - rework ogg vorbis code
1318 - make update command work on mysql servers with LOCAL_INFILE
1319 disabled
1320 - gui: improved stream I/O (slots)
1321 - simplified audio format API
1322 - para_pob_ogg is gone
1323
1324 ------------------------------------
1325 0.1.5 (2004-12-31) "opaque eternity"
1326 ------------------------------------
1327
1328 Let's slide gently into the new year.
1329
1330 - new: para_slider (not built automatically, type "make
1331 para_slider" to build). A toy for those who always felt that
1332 creating stream definitions is difficult. See screenshots,
1333 README and FEATURES for more info.
1334 - improved signal handling. Fixes server segfault on SIGHUP
1335 for linux kernels newer than Aug 24 2004 and makes para_gui
1336 race-free.
1337 - reload database tool on SIGHUP
1338 - improved help message for sl
1339 - do not log "broken pipe" messages as errors. They are
1340 perfectly ok.
1341 - fix wrong error message on permission errors
1342
1343 -----------------------------------------
1344 0.1.4 (2004-12-19) "tunneling transition"
1345 -----------------------------------------
1346
1347 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1348 Hopefully, most of them got wiped out with this release. Some
1349 enhancements went also in.
1350
1351 - improved error diagnostics for all commands
1352 - stradd/picadd: overwrite previous contents if entry already
1353 exists, rather than returning errors
1354 - stradd: use current stream if invoked without args
1355 - faster (and hopefully more stable) ogg-vorbis handling
1356 - para_krell: reap children to avoid zombie-flooding in case
1357 no server is running
1358 - si: report also server pid
1359 - server: don't busy-loop if dbtool reports only invalid files.
1360 - gui: CTRL+C works again, fix stream_read command line option
1361 - fix pic_add, hist
1362 - fix mysql dbtool startup in case no database exists
1363 - many small fixes and cleanups
1364
1365 ---------------------------------------
1366 0.1.3: (2004-12-10) "vanishing inertia"
1367 ---------------------------------------
1368
1369 Starting from this release, the database tools are integrated in the
1370 server binary. This decreases server startup time, reduces code size
1371 and speeds up database commands. However, the layout of the underlying
1372 mysql database changed only slightly and 0.1.3 should be backwards
1373 compatible in that respect.
1374
1375 Visible changes:
1376
1377 - If mysql is not detected at compile time, or fails to init
1378 at runtime, fall back to the dopey database tool which should
1379 always work.
1380 - para_dbtool and dbtool.conf are gone. All mysql specific
1381 options are read from server.conf and are prefixed by 'mysql_'.
1382 - new command: cdt (change database tool)
1383 - new command line option: dbtool (choose startup database tool)
1384 - The name of current stream is now stored in the database,
1385 so paraslash remembers its current stream when restarted.
1386 - new command: csp (change stream and play)
1387 - para_gui also reports current database tool and server uptime
1388
1389 -------------------------------------------
1390 0.1.2: (2004-11-28) "spherical fluctuation"
1391 -------------------------------------------
1392
1393 Point release before the big dbtool changes go in.
1394
1395 - dbtool: rename ca to cam (copy all meta data). It now also
1396 copies numplayed and lastplayed time as well as the picture
1397 id.
1398 - fix endless-loop-bug caused by mp3 files with invalid header
1399
1400 -----------------------------------------
1401 0.1.1: (2004-11-05) "floating atmosphere"
1402 -----------------------------------------
1403
1404 - gkrellm plugin
1405 - new dbtool command: mbox. Browse your sound-file collection
1406 with your favorite mail reader.
1407 - several small fixes
1408
1409 -------------------------------------
1410 0.1.0: (2004-10-22) "rotating cortex"
1411 -------------------------------------
1412
1413 - fix logging bug for loglevel > VERBOSE
1414 - fix skip command
1415 - correct timings for vbr mp3s
1416 - modular audio format support
1417 - ogg-vorbis support (experimental)
1418 - new server option: autoplay
1419
1420 -----------------------------------------
1421 0.0.99: (2004-07-25) "harmonic deviation"
1422 -----------------------------------------
1423
1424 - rename projectname from icc to paraslash (play, archive, rate
1425 and stream large audio sets happily)
1426 - paraslash is no longer restricted to one particular audio
1427 streaming software
1428 - new dbtool commands (stradd, strq, strdel) for easy stream
1429 managment w/o configuration file. That obsoletes stream_defs
1430 file/config option for dbtool.
1431 - picadd accepts jpeg data from stdin
1432 - new server commands: ps (select previous stream), sc (song change)
1433 - new default pictures for sdl_gui
1434 - gui: new key_map option for binding commands and internal
1435 functions to arbitrary keys, nice help screen, rip out
1436 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1437 show silly logo on startup
1438 - new executables: para_fade for fading volume, para_dbadm for
1439 manipulating attributes
1440 - cdb adds _all_ tables to mysql database
1441 - revised and beautified documentation
1442 - sample dbtool rewritten in C
1443 - autoconf
1444
1445 ---------------------------------------------
1446 0.0.98: (2003-12-26) "incremental smoothness"
1447 ---------------------------------------------
1448
1449 - kick icecast in favour of poc. That removes some races and reduces
1450 core code considerably.
1451 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1452 give finer info on afs' status.
1453 - gui can start decoder (see config options). Further new gui
1454 commands: refresh (^L), jmp (F1-F10)
1455 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1456 terminates gui. This fixes dead instances consuming memory
1457 continuously.
1458 - new dbtool command: verb for sending verbatim sql queries.
1459 - fix pid_list races (by removing pid_list)
1460 - codename funnies
1461
1462 --------------------
1463 0.0.97: (2003-10-26)
1464 --------------------
1465
1466 - installation prefix now defaults to /usr/local
1467 - new commands for gui: snozze, sleep and reread config
1468 - config file for gui and sdl_gui
1469 - fix problems with filenames containing funny characters
1470 (reported by Thomas Forell)
1471 - improved signal handling for gui, now it rereads conf on SIGHUP
1472 - new dbtool command: cdb (create database)
1473 - switch from argtable to gengetopt
1474 - major code cleanup and speed improvements
1475 - fix several potential buffer overflows

1484 - Major feature enhancements for icc_gui including dynamic text
1485 placement and the top/bottom window design
1486 - vrfy/clean now also checks for NULL values in attributes as
1487 well as for invalid picture pointers
1488 - fix long outstanding case sensitivity bug
1489 - many small fixes and cleanups
1490
1491 -------------------
1492 0.0.95 (2003-06-29)
1493 -------------------
1494
1495 - sdl gui runs much faster
1496 - new dbtool command: ca (copy attributes)
1497 - count and display number of times the song has been played
1498 - new feature: scoring
1499 - command line options for sdl_gui
1500 - simpler syntax of streams file
1501 - decrease network traffic of stat
1502 - fix zombie bug

1511 - internal mp3info
1512 - stat shows also id3 tag info
1513 - new sdl based gui
1514 - log flodding bug fixed
1515 - many small fixes and cleanups
1516
1517 -------------------
1518 0.0.93 (2003-03-28)
1519 -------------------
1520
1521 - colors for icc_gui
1522 - icc_gui sets volume directly (linux only)
1523 - proper locking that fixes some races
1524 - fix security bug that caused commands to be executed even
1525 with unsufficient permissions
1526 - new command: hup to make all servers reread their configuration file
1527 - icecast meta data streaming
1528 - many small fixes and cleanups
