42 ---------------------------------------
43
44 This release contains a few important fixes which have accumulated in

59 0.6.3 (2021-02-18) "generalized activity"
60 -----------------------------------------
61
62 It has been a while since the last release, but paraslash-0.6.3
63 finally has arrived. It contains a fair number of improvements,
64 features and fixes all over the place.
65
66 - The ff command now accepts a negative argument to instruct the
67 virtual streaming system to jump backwards in the current audio
68 stream. The old syntax (e.g., "ff 30-") is still supported but it
69 is deprecated and no longer documented. The compatibility code is
70 sheduled for removal after 0.7.0.
71 - para_afh: New option: --preserve to reset the modification time to
72 the value of the original file after meta data modification.
73 - Overhaul of the compress filter code. The refined algorithm should
74 reduce clipping. The meaning of --aggressiveness has changed, see the
75 updated and extended documentation of the compress filter for details.
76 - Cleanup of the audio format handler code.
77 - We now build the tree using the .ONESHELL feature of GNU make,
78 which results in a significant speedup.
79 - Two robustness fixes for FreeBSD.
80 - para_client now supports RFC4716 private keys as generated with
81 ssh-keygen -m RFC4716. In fact, this key format has been made the
82 default, and the former PEM keys will be depreciated at some point.
83 - The ogg audio format handlers learned to detect holes and now report
84 the correct duration also if ogg pages are missing in the file. This
85 affects ogg/vorbis ogg/speex and ogg/opus.
86 - Robustness improvements for para_mixer.
87 - A fix for an old bug that could cause the server to crash or report
88 garbage in its status output.
89 - New para_play option: --end-of-playlist
90 - Streaming m4a files over udp has been improved.

97 0.6.2 (2018-06-30) "elastic diversity"
98 --------------------------------------
99
100 The main new feature of this release is the --listen-address option
101 for para_server and para_audiod. But there are also a large number of
102 small improvements and bug fixes all over the place. The user-visible
103 changes include
104
105 - para_gui no longer waits up to one second to update the screen when
106 the geometry of the terminal changes.
107 - Minor documentation improvements.
108 - Improvements to the crypto subsystem.
109 - The server subcommand "task" has been deprecated. It still works,
110 but prints nothing. It will be removed in the next major release.
111 - Server log output is now serialized, avoiding issues with partial
112 lines.
113 - It is now possible to switch to a different afs database by changing
114 the server configuration and sending SIGHUP to the server process.
115 - New server options: --listen--address, --http-listen-address and
116 --dccp-listen-address. These options restrict the set of listening
117 addresses of the TCP and DCCP sockets of the server process.
118 - The help commands of server, audiod, play now support --long. By default,
119 the short help is shown.
120 - The code which merges the command line options with the config file
121 options has been consolidated.
122 - If the current audio file is renamed, the status items are now updated
123 accordingly.
124 - After the server process received SIGHUP, changes to the current audio
125 file did not trigger an update of the status items. This has been fixed.

132 0.6.1 (2017-09-23) "segmented iteration"
133 ----------------------------------------
134
135 The highlight of this release is the version 2 mood parser. But there
136 is a lot more than that, as summarized in the list below. And of
137 course we have many small usability improvements and bug fixes not
138 mentioned here.
139
140 - A more intuitive syntax for moods ("version 2 moods"). The
141 traditional version 1 moods are still supported but are deprecated
142 now. Removal of the version 1 mood parser is scheduled for the next
143 major release.
144 - Flex and bison are now required to build para_server.
145 - New sort order for the ls command: -s=h sorts the ls output by hash
146 value of the audio file.
147 - autogen.sh now runs the test suite after a successful build.
148 - The contents of overview.pdf have been integrated into the user
149 manual.
150 - Fixed sized audio format headers for ogg/opus streams.
151 - The doxygen source browser has been disabled temporarily. The
152 API reference is still online, though.
153 - Overhaul of the source code documentation.
154 - The deprecated --full-path option of the ls command has been
155 removed. It was a no-op since 0.6.0.
156 - The wma decoder has been cleaned up and its bitstream API made
157 more robust.
158 - The image/lyrics ID status items of the current audio file are now
159 updated on changes. This affects para_gui, which used to report the
160 old value until EOF.

167 0.5.8 (2017-09-23) "branching parabola"
168 ---------------------------------------
169
170 A couple of fixes for serious old bugs have accummulated in the maint
171 branch since paraslash-0.5.7 was released nine months ago. So here
172 is another 0.5.x release. As usual, all commits in the maint branch
173 have been merged into master, so the upcoming paraslash-0.6.1 also
174 contains them. For details see the git log.

180 -------------------------------
181 0.6.0 (2017-04-28) "fuzzy flux"
182 -------------------------------
183
184 The highlights of this release are the conversion of all option parsers
185 to the lopsub library and the improved AAC support. But there are
186 many other user-visible changes all over the place. Also a lot of
187 old cruft has been removed, leading to incompatible changes. Hence
188 the new major version number.
189
190 - Support for Mac OS X has been removed.
191 - On Linux systems, glibc-2.17 or newer is required to build the
192 source tree.
193 - Support for RSA public keys in ASN format (as generated by openssl
194 genrsa) has been removed. These keys have been deprecated since
195 2011, so users should have long switched to keys generated with
196 ssh-keygen(1).
197 - If libgcrypt is used as the crypto library, we now require version
198 1.5.0 (released in 2011) or later.
199 - The insecure RC4 stream cipher has been removed. It was superseded
200 by aes_ctr128 three years ago but the RC4 code had been kept for
201 backwards compatibility.
202 - On Linux, abstract unix domain sockets are used unconditionally.
203 - The "install" target no longer strips executables, the new
204 install-strip target can be used to get the old behaviour.
205 - The clean targets have been renamed: clean2 is gone, and the new
206 mostlyclean removes only the executables and object files.
207 - New target: check (identical to test).
208 - The DESTDIR make variable is honored to prepend a path to the
209 installation directory. This feature is orthogonal to the --prefix
210 option to configure.
211 - Minor WMA cleanups.
212 - The aac audio format handler has been rewritten to use the mp4ff library.
213 See the manual for how to install the library on your system.
214 - New status item: max_chunk_size. The value is stored in a previously
215 unused field of the afhi object of the aft table. Although backwards
216 compatible, users are encouraged to re-add m4a files to populate
217 the new field.
218 - No more chunk tables for aac. Chunk boundaries are determined
219 dynamically at stream time.
220 - Release and master branch tarballs are now compressed with xz rather
221 than bzip2.
222 - The lopsub package is required to install the paraslash package.
223 Gengetopt is no longer needed.
224 - make dep is gone. Dependencies have been created automatically for
225 a long time and it was never necessary to run make dep manually.
226 - para_gui lost its --timeout option.
227 - Most manual pages have been extended to include an overall
228 description of the command.
229 - The --stream-delay option of para_audiod has been removed. It had
230 been a no-op for many years.
231 - The deprecated --path option of the server ls command has been
232 removed. The command now prints full paths by default, making
233 --full-path a no-op. Hence --full-path has been depreacted and is
234 scheduled for removal in v0.6.1.
235 - It is now possible to use 'CFLAGS' to override the default compiler
236 options.
237 - para_fade has been renamed to para_mixer. The four modes of operation
238 (set, fade, snooze, sleep) are implemented as subcommands of the
239 new program.
240 - The sleep subcommand of para_mixer (former sleep mode of para_fade)
241 lost its --wake-hour and --wake-min options in favor of the new
242 --wake-time option which also accepts relative wakeup times like
243 "+9:30".
244 - The new --fade-exponent option of para_mixer allows for non-linear
245 channel fading.
246 - The new logo.

253 0.5.7 (2016-12-31) "semantic density"
254 -------------------------------------
255
256 Mostly a bug fix release, and a bunch of internal improvements.
257 The only user-visible changes are the sanity checks for the touch
258 command and the new options to the ls command.
259
260 - Speedup of the base64 decoder.
261 - One of the two source browsers has been removed from the web pages.
262 The doxygen API reference still contains an HTML version of each
263 source file.
264 - Two race conditions in para_server have been fixed.
265 - ls -p is now deprecated in favor of -F or -b. See the help text of
266 the ls command for details.
267 - The openssl code has been adjusted to work also with openssl-1.1.
268 - The wma decoder and audio format handler now correctly decodes
269 files with unusual block sizes.
270 - We now compile with -Wformat-signedness if possible.
271 - The touch command now refuses to set an invalid image or lyrics ID.
272 - New section on contributing for the user manual.
273 - Major simplification of the error subsystem.

280 0.4.14 (2016-12-31) "branching oscillation"
281 -------------------------------------------
282
283 Many fixes for nasty bugs have accumulated over the years since 0.4.13
284 was released in 2013. This release contains all of them. It is the
285 last v0.4.x release, so v0.4.x is now end of life. The maint branch
286 of the git repository has been forwarded to v0.5.7 and will start to
287 receive important fixes for 0.5.x, which is now in maintenance mode.
288
289 - Fix for the "double encryption bug" with gcrypt, which caused
290 garbage to be sent to stat clients.
291 - The "prev" command of para_play now works as expected.
292 - Invalid parameters for the begin and end chunk no longer cause
293 the afh receiver of para_recv to segfault.
294 - A fix for an assertion that triggered in the FEC slice setup code.
295 - Closing the terminal with a running para_gui causes the process to
296 die, rather than using 100% of CPU time.
297 - para_gui no longer shows stale information about the previous
298 audio file.
299 - A fix for a bug in the fec decoder which caused aborts if the buffer
300 pool filled up.
301 - The assertion in the buffer tree code no longer triggers.
302 - The "afs_event: table moods, event 0: key already exists in rbtree"
303 error no longer occurs on attribute changes.
304 - A NULL pointer dereference in com_sender() has been fixed.
305 - The -i option of lsatt works as advertised.
306 - Various fixes for the build system.

313 0.5.6 (2016-07-10) "cascading gradient"
314 ---------------------------------------
315
316 The highlight of this release is the new -m flag for para_afh which
317 lets it modify the meta tags of the given audio file(s). This feature
318 is supported for all audio formats. Many small cleanups and bug fixes
319 not mentioned here have accumulated and are also part of the release.
320
321 - para_afh learned to modify meta tags of mp3 wma ogg spx
322 opus flac aac files.
323 - afs commands propagate error codes to the client.
324 - The check command now also checks the attribute table for
325 inconsistencies.
326 - New -v flag for the version command (print verbose version string)
327 - New option --priority for para_server and para_audiod.
328 - New mood methods: image_id and lyrics_id.
329 - The manual and this NEWS file have been converted to markdown.
330 - Support for the compile-time loglevel feature has been removed.
331 - Cleanup of the wma decoder and bitstream code.
332 - Improved wide-character support and fixes related to signal handling.
333 - para_gui no longer reports 100% playing time at the stream start.
334 - Opus cleanups.

342 --------------------------------------
343
344 Many new features and a lot of other improvements.
345
346 - On Linux systems, local sockets are now created in the
347 abstract name space by default. This allows to get rid of
348 the socket specials in /var/paraslash.
349 - The --user-allow option of para_audiod now accepts also
350 usernames rather than only user IDs.
351 - New autoconf macros to avoid duplication in configure.ac.
352 - Status items (as shown by para_gui) are updated correctly
353 when the meta information of the current audio changes.
354 - para_server and para_audiod no longer refuse to start in
355 the background if no log file is given. Instead, all log
356 messages go to /dev/null in this case.
357 - Web page cleanup.
358 - New syntax for the -l and -s options of the ls command.
359 These options should now be specified as -l=v rather than
360 -lv, for example. The old syntax still works, but support
361 will be dropped in v0.6.0.

391
392 Not many new features, but lots of fixes and usability improvements.
393
394 - para_gui has been converted to use the paraslash scheduler.
395 - Various alsa-related fixes, mostly for the raspberry pi.
396 - Many scheduler improvements and cleanups.
397 - The test suite has been extended to include sanity checks
398 for the generated man pages.
399 - ao_writer fixes. This writer was in a quite bad shape. Many
400 serious bugs have been fixed.
401 - new audiod command: version.
402 - Minor improvements to the bitstream API.
403 - The cpsi command now prints a meaningful error message if
404 none of the given patterns matched any audio file.

413
414 The new sync filter, the AES_CTR128 stream cipher and the overhauled
415 network code are the highlights of this release. It also includes a
416 fair number of smaller fixes and improvements not mentioned here.
417
418 - The new sync filter synchronizes playback between multiple
419 clients.
420 - Connections between para_server and para_client are now
421 encrypted by means of AES rather than RC4 if both sides
422 support it. RC4 is still available as a fallback. This
423 feature is fully transparent, i.e. no command line options
424 are necessary, and a client linked against openssl can
425 speak with a server linked against libgcrypt and vice versa.
426 - Major cleanup of the networking subsystem.
427 - Improvements to para_fade: the new set mode, multi-channel
428 initial volumes, better error logging.
429 - The man pages of para_audiod, para_filter, para_recv, and
430 para_write contain the relevant options for receivers, filters,
431 writers. This broke in 0.5.0.
432 - ogg/vorbis latency improvements.
433 - Improved user manual.
434 - Minor fixes to avoid clang warnings.

441 0.5.1 (2013-12-20) "temporary implication"

443
444 Lots of fixes and improvements all over the place, and a major overhaul
445 of the build system.
446
447 - Audiod improvements and fixes.
448 - Buffer tree robustness improvements.
449 - Cleanup of the mood subsystem.
450 - Fixes and cleanups for the flac decoder.
451 - Latency improvements for the ogg/opus decoder.
452 - Crypto support is now optional. On systems without
453 openssl/gcrypt, the build succeeds but para_server,
454 para_audiod, para_client won't be built.
455 - The build system now works for cross-compile setups.
456 - The dependency tree has been flattened, which speeds up
457 builds and avoids to recreate the man pages on every change.
458 - The error code helper has been rewritten from perl to C,
459 which further improves build time.
460 - Many small bugs in the build system have been identified
461 and fixed.

468 0.5.0 (2013-08-23) "invertible validity"
469 ----------------------------------------
470
471 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
472
473 - The sideband compatibility code has been removed, hence
474 sideband connections (introduced in 0.4.11) are now mandatory.
475 - Addblob commands can produce output.
476 - The stat command no longer sends garbage when para_server was
477 compiled against libgcrypt.
478 - Dependencies for gengetopt files are computed automatically.
479 This eliminates a constant source of build bugs.
480 - The setatt command now accepts file name patterns rather than only
481 path names.
482 - overview.pdf is now based on dia, a simple diagram creation program.
483 The new version is much more detailed and contains descriptions of
484 the various programs of the paraslash package.
485 - The separator of all multi-word options has been changed from
486 underscore to dash. For example --log_color becomes --log-color.
487 - Overhauled web pages and the new logo.

496
497 One more 0.4.x release before the API-breaking changes for 0.5.0 go
498 in. The main features of this release are the ogg/opus audio format,
499 and UTF-8 support, but it includes also tons of other improvements
500 and fixes all over the place.
501
502 - New audio format: ogg/opus.
503 - UTF8 support for para_gui and the mp3 audio format handler.
504 - Scheduler improvements and fixes.
505 - The obsolete gettimeofday() function has been replaced
506 by clock_gettime() on systems which support it.
507 - Speed and usability improvements for para_gui.
508 - para_client now restores the fd flags of stdin and stdout
509 on shutdown.
510 - Improved manual pages.
511 - Consistent version strings for all executables.
512 - Reduced dependencies on generated files result in fewer
513 recompilations on changes.
514 - Performance improvements for the compress filter.
515 - Improved downloads web page.
516
517 -----------------------------------------
518 0.4.12 (2012-12-20) "volatile relativity"
519 -----------------------------------------
520 The new command line player, the resample filter, ALSA support for
521 para_fade, and the improved build system are the highlights of this
522 release which probably marks the end of the 0.4.x series.
523
524 - The afh receiver and the para_play executable.
525 - The resample filter: A sample rate converter based on
526 libsamplerate.
527 - The "versions" directory has been removed from the master
528 branch. The tarballs of the old releases are now available
529 in the new "releases" branch.
530 - Overhaul of the build system: All generated files are now
531 written to the "build" directory.
532 - The modular mixer API and the alsa mixer.
533 - Minor fixes for the osx writer.
534
535 --------------------------------------
536 0.4.11 (2012-07-20) "mutual diversity"
537 --------------------------------------
538
539 The major feature in this release is the new sideband API for
540 client-server communication. This API will be used exclusively starting
541 with 0.5.0, which breaks backward compatibility but allows to get rid
542 of quite some compatibility code. Other noteworthy changes include
543 decoder latency improvements and a long-standing bug fix for the
544 ALSA writer.
545
546 - Sideband connections: If both para_server and para_client
547 support this feature, data is sent as a multiplexed stream.
548 - The --no_default_filters option of para_filter has been
549 removed.
550 - Several fixes and latency improvements to various decoders.
551 - The ALSA writer now limits the prebuffer time to 500ms.
552 - Documentation improvements.
553 - Overhaul of the command_util.sh script.
554 - Fixes for some minor problems found by the clang analyzer.
555 - Compiles (almost) without warnings on gcc-3.
556 - Robustness improvements of the buffer tree code.
557
558 ------------------------------------------
559 0.4.10 (2012-03-30) "heterogeneous vacuum"
560 ------------------------------------------
561
562 Nothing earth-shaking in this release, but quite a few usability
563 improvements and the usual mix of cleanups and fixes.
564
565 - The --no_default_filters option of para_filter has been
566 deprecated. It still works but has no effect and will be
567 removed in the next version.
568 - para_gui now prints also the stderr output of the executing
569 command in the bottom window.
570 - Cleanup and consolidation of the various wrappers for
571 write(), writev(), send() and friends.
572 - The obscure error messages on mmap() failures have been
573 replaced by meaningful messages. This affects mainly
574 para_afh.
575 - para_audioc: Cleanups and memory leak fixes.
576 - Test 0004-server no longer fails if para_server is not
577 being built.
578 - New configure options: --with-id3tag-{headers,libs}.
579
580 -------------------------------------
581 0.4.9 (2011-12-06) "hybrid causality"
582 -------------------------------------
583
584 Support for another audio format, interactive mode for para_client
585 and para_audiod and many small improvements/fixes all over the place.
586
587 - Support for flac, the free lossless audio codec.
588 - Fix for an endless loop in the mp3 decoder for certain
589 (corrupt) mp3 files.
590 - When executed without specifying a command, para_client
591 and para_audioc start an interactive shell (requires
592 libreadline being installed). The interactive mode offers
593 full tab completion and command line history.
594 - autogen.sh now detects a distcc setup and adjusts the
595 parameter for the -j option of make accordingly.
596 - Shared memory areas are no longer restricted to 64K. We now
597 detect the maximal size of a shared memory area at runtime.
598 - cleanup of the internal uptime API.
599 - para_server prefaults the mmapped audio file to avoid
600 delays on slow media.
601 - A new test for the test-suite that exercises the
602 communication between para_server and para_audiod.
603 - The alsa writer eats up less CPU cycles when configured to
604 use the DMIX plugin.
605 - Simplified and unified receiver code.
606 - Makefile cleanups.
607 - Commands which print a list of matching audio files now
608 emit a meaningful error message if no audio file matched the
609 given pattern(s).
610
611 --------------------------------------
612 0.4.8 (2011-08-19) "nested assignment"
613 --------------------------------------
614
615 Gcrypt support, the overhauled osx writer and regex format specifiers
616 are the highlights of this release.
617
618 - support for libgcrypt as a drop-in replacement for openssl.
619 Run configure --enable-cryptolib=gcrypt to link against
620 libgcrypt. The two crypto implementations are compatible to
621 each other, i.e. a para_client executable linked against
622 gcrypt can connect to para_server linked against libssl
623 and vice versa.
624 - Rewrite of the osx writer (output plugin for Mac OS).
625 - audiod: The format specifier for receivers, filters and
626 writers is now treated as a regular expression. This allows
627 to replace 5 lines in the config file (one for each audio
628 format) by one single line. See the manual for details.
629 - The \*.cmdline.[ch] files are no longer contained in the released
630 tarballs. This reduces the size of the tarballs but requires
631 gengetopt to build the tarball.
632 - Compiles cleanly also with llvm/clang.
633 - Corrupt mp3 files are handled more gracefully.
634 - The alsa writer uses poll fds instead of computing timeouts.
635 - Cleanup of the generic writer API.
636 - sched: Optimized zero timeouts.
637 - vss timeout cleanups.
638 - oggdec fixes and improvements.
639
640 --------------------------------------
641 0.4.7 (2011-06-01) "infinite rollback"
642 --------------------------------------
643
644 The new ao writer, support for ssh RSA keys and a couple of other
645 enhancements.
646
647 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
648 platforms through the libao audio library.
649 - Support for RSA keys generated with ssh-keygen.
650 - configure: improved options for ogg/vorbis/speex.
651 - The git version reported by --version always matches HEAD.
652 - The autogen script detects the number of processors and
653 runs a parallel make if possible.
654 - Major cleanup of the crypto API.
655 - Documentation updates.
656
657 ------------------------------------------
658 0.4.6 (2011-03-31) "deterministic entropy"
659 ------------------------------------------
660
661 Lots of ogg/vorbis improvements, the new test suite, enhancements
662 for para_gui and a fair amount of other bug fixes.
663
664 - For DCCP/OGG streams the audio file header is only sent once
665 at the beginning of the stream rather than periodically
666 every five seconds. This reduces network traffic and the
667 FEC group size.
668 - The vorbis comment header is replaced by an empty dummy header
669 before the header is sent over the network. This also results in
670 less network traffic and smaller FEC groups.
671 - The new "test" make target allows to perform some sanity checks prior
672 to installing the package.
673 - ogg timing fixes and performance improvements
674 - Scheduler improvements
675 - Proper exit codes for para_write
676 - para_gui: New option --theme to select a startup theme. Several
677 other improvements and fixes.
678 - aacdec error message cleanups
679 - simplified color error handling
680
681 --------------------------------------------
682 0.4.5 (2010-12-17) "symmetric randomization"
683 --------------------------------------------
684
685 Bug fixes, internal cleanups and variable-sized FEC slices.
686
687 - Contains a fix for an invalid-free-bug in the ogg audio format
688 handler code.
689 - Switching off the DCCP sender works again.
690 - para_audiod handles crashes of para_server more robustly.
691 - Internal scheduler and writer cleanups.
692 - Reduced latency due to variable-sized FEC slices.
693 - Improved documentation and error diagnostics.
694 - The build of para_server is now optional, allowing the build
695 to succeed in case libosl is not installed.
696
697 ------------------------------------------
698 0.4.4 (2010-08-06) "persistent regularity"
699 ------------------------------------------
700
701 Support for yet another audio format, para_write improvements and
702 bug fixes.
703
704 - Support for the speex codec.
705 - Support for sample formats other than 16 bit little endian.
706 - error2.h is now created by a perl script which speeds up configure
707 considerably.
708 - Fix a bug in the aac decoder which could lead to segfaults in
709 para_filter/para_audiod.
710 - Fixes for autoconf-2.66.
711
712 ----------------------------------------
713 0.4.3 (2010-07-05) "imaginary radiation"
714 ----------------------------------------
715
716 Many improvements for the DCCP and the UDP transport, the new user
717 manual and the usual mix of bug fixes and internal improvements.
718
719 - FEC support for the DCCP sender (Gerrit Renker). The new
720 --dccp_max_slice_size, --dccp_data_slices_per_group and
721 --dccp_slices_per_group options can be used to set the FEC
722 parameters for the DCCP transport.
723 - DNS lookups for UDP targets (Gerrit Renker).
724 - The new user manual replaces the README, README.afs, REQUIREMENTS
725 and INSTALL documents.
726 - Fix an end-of-file detection bug in the oggdec filter.
727 - The new nonblock API.
728 - Both options of the oggdec filter have been removed.
729 - New debug mode for the internal scheduler.
730
731 ------------------------------------------
732 0.4.2 (2010-04-23) "associative expansion"
733 ------------------------------------------
734
735 It's been some time since the last release, but finally here is
736 paraslash-0.4.2. The bulk of the changes comes from the new buffer
737 tree API, but there are changes all over the tree. Mainly performance
738 and usability improvements, but also quite some bug fixes.
739
740 - The new buffer tree API.
741 - DCCP: Support for CCID negotiation (Gerrit Renker).
742 - UDP robustness fixes.
743 - The --bufsize option for mp3dec is gone as it no longer makes sense
744 for the new buffer tree API.
745 - Fix audible buffer underruns for wma streams.
746 - The alsa writer no longer prints meaningless underrun durations.
747 - audiod: Defaults work also for udp streams. If no filter is
748 given for an audio format that is received via upd, fecdec is
749 automatically added as the first filter (along with the decoder).
750
751 ---------------------------------------
752 0.4.1 (2009-12-22) "concurrent horizon"
753 ---------------------------------------
754
755 Support for another audio format, minor feature enhancements and lots of bug
756 fixes. All fixes that have been accumulated in the maint branch (in particular
757 those mentionened in the 0.3.6 release notes) appear in this release as well.
758
759 - wma support.
760 - new afh option: --human to activate human-readable output.
761 - new server/audiod option: --log-timing to print timing information.
762 - build system improvements.
763 - source code documentation updates.
764
765 -------------------------------------
766 0.3.6 (2009-12-07) "cubic continuity"
767 -------------------------------------
768
769 Quite a few bugs have been found and fixed since 0.3.5, so here's
770 another 0.3.x release. No new features.
771
772 - Always check return value of malloc().
773 - ogg vorbis/FEC: Do not write garbage after the audio file header.
774 - exit if root privileges could not be dropped.
775 - FEC: Fix computation of extra slices.
776 - oss: Fix check for empty input buffer.
777 - Avoid buffer underruns due to filter chain output buffer constraints.
778 - server: Fix assignment of afs_pid.
779 - Don't panic if the afs database contains unknown audio formats.
780 - http/dccp: Do not send the audio file header twice.
781 - FEC: Timing improvements.
782
783 ----------------------------------------------
784 0.4.0 (2009-11-10) "simultaneous independence"
785 ----------------------------------------------
786
787 Two significant changes which require the new version number: The
788 improved authentication dialog and the fact that the database code
789 has been moved to a library, libosl. To use the new version, you have
790 to generate new RSA keys, see INSTALL for details. A shell script is
791 provided for conversion of the 0.3 database to the new 0.4 format.
792
793 - stronger crypto for client authentication
794 - the database code has been moved to a library
795 - improved status item handling
796 - cleanup of the build system
797 - The "-V" option now also prints the git version
798 - the new parser-friendly listing mode for the ls and stat commands
799 - mandatory rc4 encryption
800 - major audio format handler cleanups
801 - (id3,...) tags are no longer stored as a combined string in the database
802 - new mood methods: artist_matches, title_matches, comment_matches,
803 album_matches, year_maches, year.
804
805 --------------------------------------------
806 0.3.5 (2009-09-21) "symplectic separability"
807 --------------------------------------------
808
809 Full client support for \*BSD Unixes, complete re-write of the ogg
810 vorbis audio format handler, various improvements all over the place
811 and the usual mix of bugfixes. This release marks the end of the 0.3
812 series if no serious problems show up.
813
814 - the new oss writer (supported on \*BSD and Linux)
815 - rewrite of the ogg vorbis audio format handler. It's
816 recommended to replace the chunk tables of existing ogg
817 vorbis files in the afs database by re-adding these files
818 with "add -f".
819 - support for netmask subsets (Gerrit Renker)
820 - the new prebuffer filter
821 - improved signal handling
822 - variable fec output buffer size
823 - improved FEC timing fixes audible buffer underruns in UDP mode
824 - --log_color actually works
825 - new ls option: -d (print dates as seconds after the epoch)
826 - update to gengetopt 2.22.2
827 - support for RSA keys of size > 512 bits
828 - new option "mixer_channel" for para_fade
829
830 -----------------------------------------
831 0.3.4 (2009-05-07) "elliptic inheritance"
832 -----------------------------------------
833
834 The new udp sender, forward error correction, colored logs and various
835 other improvements. As the udp sender does not depend on any special
836 libraries, it is built unconditionally.
837
838 - The udp sender replaces the ortp sender. The new code uses forward
839 error correction to protect against packet losses. Many thanks to
840 Gerrit Renker for providing ipv6 support.
841 - The default port for udp streaming now defaults to 8000, like
842 for the http and the dccp senders/receivers.
843 - Loglevels are now specified as symbolic names, e.g.
844 "--loglevel info".
845 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
846 - para_server/para_audiod: Color support for log messages.
847 - new options for mp3dec: --ignore-crc, --bufsize
848 - new audiod option: --config-file.
849 - gengetopt cleanups.
850 - Improved help/man pages: The documentation of para_audiod,
851 para_recv, para_filter and para_write now also contains
852 all options of the available receivers/filters/writers. The
853 man page of para_fade contains a description of the different
854 modes of operation.
855 - More source code documentation.
856 - vss timing fixes.
857
858 --------------------------------------------
859 0.3.3 (2008-12-01) "axiomatic perspectivity"
860 --------------------------------------------
861
862 Internal code cleanups, bug fixes, improved tag handling and the new
863 amplification filter.
864
865 - para_server uses the generic scheduling code.
866 - overhaul of the virtual streaming system.
867 - mp3: id3 version 2 support via libid3tag (optional)
868 - ogg: vorbis comment support.
869 - aac meta info support.
870 - mp3 audio format handler cleanups.
871 - new filter: "amp" to amplify the amplitude of the audio stream
872 - new status item/database entry: amplification. It is
873 used by the amp filter to pre-amplify the audio stream.
874 - fix a close-without-open bug in para_write.
875 - fix a bug in com_init() which was introduced in 0.3.2.
876 - better error diagnostics for para_client.
877
878 -----------------------------------------
879 0.3.2 (2008-04-11) "probabilistic parity"
880 -----------------------------------------
881
882 The new para_afh executable, scheduling and documentation improvements.
883
884 - new ls option: -lc (list chunk table)
885 - new executable: para_afh, the stand-alone audio file handler tool
886 - afs commands can send output more than SHMMAX (32MB on Linux). This
887 also reduces the memory usage of commands that produce large amounts
888 of output.
889 - major scheduler and audiod cleanups.
890 - more detailed and much nicer man pages.
891
892 ---------------------------------------
893 0.3.1 (2008-02-23) "liquid interaction"
894 ---------------------------------------
895
896 A mix of cleanups, bug fixes, improvements, and some new features. No
897 significant changes to the new database (osl) code, which is generally
898 a good sign.
899
900 - Share some similar/duplicate code between the http and the
901 dccp sender.
902 - Generic access control lists for paraslash senders.
903 - dccp sender: Access control lists, connection limiting and support
904 for the allow,deny,on,off,help sender commands.
905 - The default dccp port changed from 5001 to 8000 (suggested by
906 Gerrit Renker).
907 - para_server starts even if not all public keys could be loaded.
908 - Audiod performance improvements.
909 - fix a bug in the "off" command of the http sender.
910 - fix some fd and memory leaks.
911 - Update to gengetopt-2.22.
912
913 -------------------------------------
914 0.3.0 (2008-01-12) "solar saturation"
915 -------------------------------------
916
917 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
918
919
920 Usually one might expect lots of new features AND a big increase in size
921 for a major release like this.
922
923 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
924 ever. The decrease in size is mostly due to the removal of some
925 graphical tools (which were only quick hacks anyway). But also the
926 fact that the mysql code is gone cuts down the size a bit.
927
928 Being independent of mysql comes at a cost: The fact that paraslash
929 now contains its own database (the object storage layer, osl) increases
930 the (stripped) binary size of para_server by ~50K on i386.
931
932 - no more restrictions on unique basenames.
933 - independent of mysql: The new self-contained object
934 storage layer (osl) replaces the mysql database.
935 - New executable para_fsck: Check integrity of osl tables.
936 - Lyrics support.
937 - Reliable audio file move/rename detection.
938 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
939 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
940 Solaris (sparc64).
941 - the new osl-based audio file selector (afs) replaces the random,
942 the playlist and the mysql selector of paraslash-0.2.x.
943 - IPv6 support (thanks to Gerrit Renker).
944 - paraslash-0.2.x streams are now called "moods". Writing
945 0.3.x-mood definitions should be both easier and more
946 powerful than writing 0.2.x-stream definitions.
947 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
948 been removed. The world is a better place without them. However,
949 para_gui is still there.
950 - afs tracks audio file selection also in playlist mode.
951 - few easy-to-use afs commands replace the many not-so-easy-to-use
952 mysql commands (and are available also in playlist mode).
953 - Improved error subsystem.
954 - The earth-shaking new logo.
955
956 -----------------------------------------
957 0.2.17 (2007-11-20) "isotropic threshold"
958 -----------------------------------------
959
960 Mainly bugfixes and cleanups in this version which marks the end of
961 the 0.2.x series if no serious bugs show up after the release.
962
963 - mysql_selector: fix a locking bug.
964 - universal chunk queueing.
965 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
966 to Gerrit Renker).
967 - be more carful wrt. signed vs. unsigned argument passing.
968 - cleanup error.h and fix some references to invalid error
969 codes.
970 - update to gengetopt-2.21.
971 - update to ortp-0.13.1.
972 - autoconf: extend checks for headers, library functions and
973 compiler characteristics.
974 - Fix streaming of large mp3 files.
975 - Fix an off-by-one bug in playlist handling.
976
977 --------------------------------------
978 0.2.16 (2007-04-05) "neural discharge"
979 --------------------------------------
980
981 The main change in this release is the major audio format handler
982 cleanup which removes some similar/duplicate code and makes it easier
983 to implement plugins for other audio formats. Of course, the usual mix
984 of other improvements/changes/bugfixes also made it into the release.
985
986 - simplified audio format handlers (most of the handling functions
987 were moved one layer up to the virtual streaming system).
988 - para_server uses mmap to read audio files
989 - repositioning of mp3 streams is much faster, in particular for
990 jumping near the end of large mp3 files.
991 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
992 and AFS_WRITE.
993 - fix a bug in para_filter that caused decoding of aac files
994 to start only after a few seconds.
995 - fix osx_writer hangs
996 - simplified dccp code (thanks to Gerrit Renker)
997 - the compress filter works also on big endian systems (ppc)
998
999 -----------------------------------------
1000 0.2.15 (2007-02-16) "inductive resonance"
1001 -----------------------------------------
1002
1003 Minor improvements, more documentation and a bunch of bug fixes.
1004
1005 - para_server: The server.users file is only read once on server
1006 startup rather than for each connection
1007 - mp3dec: Fix decoding of corrupt mp3 files
1008 - afs (audio file sender) is now called vss (virtual streaming
1009 system). Consequently, the permission flags specified in
1010 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
1011 become VSS_READ and VSS_WRITE respectively.
1012 - para_audiod/para_filter: Fix a bug that caused the last chunk
1013 of audio data not being written under certain circumstances
1014 - audiod: compute the difference of server time and local time
1015 correctly
1016 - para_server/para_audiod: Fix some memory leaks
1017 - documentation improvements
1018 - configure.ac: fix checks for para_krell
1019 - new man pages
1020
1021 -------------------------------------------
1022 0.2.14 (2006-10-15) "transient singularity"
1023 -------------------------------------------
1024
1025 The only major enhancement of this version is the osx writer which completes
1026 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
1027 until now for reasons beyond the scope of this changelog entry.
1028
1029 - new output plugin for Mac Os: the osx writer
1030 - rename configure command line options from --enable-xxx-headers to
1031 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
1032 - configure: new command line options: --with-mad-headers,
1033 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
1034 - some robustness fixes
1035 - dymamic audio format recognition for audiod
1036 - para_server: new command line option: --autoplay_delay
1037 - para_audiod: new command line option: --clock_diff_count
1038
1039 ---------------------------------------
1040 0.2.13 (2006-07-14) "sonic convolution"
1041 ---------------------------------------
1042
1043 A bunch of new features and core changes.
1044
1045 - the new paraslash scheduler, short and sweet.
1046 - Support for m4a/mp4 files via the new aac audio format
1047 handler/filter (requires libfaad).
1048 - each writer has its own command line parser, just like
1049 para_recv and para_filter.
1050 - para_client and para_audioc use the error subsystem
1051 - writers are integrated in para_audiod (currently linux-only)
1052 - para_client is integrated in para_audiod
1053 - random/playlist selector: improved info strings
1054 - new audiod commands: tasks, kill
1055 - update to libortp-0.10.1
1056 - para_fade: wake time defaults to 8 hours from now
1057 - update to autoconf-2.60
1058
1059 ------------------------------------------
1060 0.2.12 (2006-05-12) "oriented abstraction"
1061 ------------------------------------------
1062
1063 Many user-visible changes in this release and lots of new
1064 features:
1065
1066 - the new optional dccp sender/receiver. It uses the datagram
1067 congestion control protocol. You'll need a fairly new kernel
1068 for this.
1069 - paraslash works on Mac OS X (thanks to Gerd Becker)
1070 - para_play renamed to para_write
1071 - modular output plugin design (writers) for para_write
1072 - new file_writer output plugin for para_write
1073 - compress filter speed improvements
1074 - update to libortp-0.9.1
1075 - update to gengetopt-2.17rc
1076 - para_client no longer depends on libreadline (as the
1077 code for the interactive mode was removed).
1078 - gcc-2-95 is no longer a supported compiler. It may still
1079 work, but it gets no more testing.
1080 - the tarball no longer contains the screenshot images which
1081 reduces its size quite a bit.
1082 - configure: new command line options: --enable-mysql-headers
1083 and --enable-mysql-libs
1084
1085 ------------------------------------
1086 0.2.11 (2006-03-11) "atomic duality"
1087 ------------------------------------
1088
1089 Here it is, the first paraslash release developed with git. There
1090 are fairly many user-visible changes in this release. As two out of
1091 the three "database tools" of paraslash don't use a database at all,
1092 they are now called "audio file selectors" instead.
1093
1094 - the cdt command (change database tool) becomes chs (change
1095 selector)
1096 - no more colon separators: The syntax of some options of
1097 para_audiod and para_filter have changed. Use --help for
1098 more info (and some examples).
1099 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
1100 - switch from cvs to git (should've done that earlier)
1101 - the new ipc subsystem
1102 - new audio file selector: playlist
1103 - para_server: the dopey selector is now called "random",
1104 and is the default selector. Use the --selector option to
1105 choose another selector at startup, or the chs command to
1106 change the selector at runtime.
1107 - X86_64 fixes (thanks to Steffen Klassert)
1108 - para_play fixes
1109
1110 --------------------------------------
1111 0.2.10 (2006-02-17) "cyclic attractor"
1112 --------------------------------------
1113
1114 Huge documentation update, a scrollable window for para_gui, ortp
1115 improvements, and of course many small fixes not mentioned here.
1116 The diffstat below is rather misleading as most insertions are due
1117 to the new source documentation.
1118
1119 - autoconf cleanup
1120 - para_server also uses the new error subsystem
1121 - lots of new documentation (UTSL)
1122 - gui improvements:
1123 - keysyms for cursor keys and for next/previous page keys
1124 - scrollable output window
1125 - new internal commands: scroll up/down, page up/down
1126 - fix color of command output.
1127 - ortp: the --chunk_time and --header flags are no longer needed
1128 for para_recv/para_audiod as this information is now encoded in
1129 each rtp packet sent by para_server.
1130
1131 -------------------------------------------
1132 0.2.9 (2006-01-24) "progressive turbulence"
1133 -------------------------------------------
1134
1135 Internal audiod receivers/filters, the new error subsystem and
1136 a lot of small improvements.
1137
1138 - para_recv and para_filter are integrated into the para_audiod
1139 binary, i.e. audiod no longer spawns a new process for
1140 each receiver/filter. As para_recv and para_filter might be
1141 useful as standalone programs, they still get built (linked
1142 against the same object files that are also used for audiod).
1143 - further ortp timing improvements should reduce the CPU usage
1144 of the ortp receiver.
1145 - improved audio grabbing. The 'grab' command of para_audiod
1146 has its own set of command line options. Read the output of
1147 "para_audioc help grab" for more info.
1148 - oggdec: configurable input prebuffer size.
1149 - the new error subsystem gives better error diagnostics
1150 and reduces code size.
1151
1152 -----------------------------------------
1153 0.2.8 (2006-01-02) "dynamic accumulation"
1154 -----------------------------------------
1155
1156 The new modular filter design and the para_play-hangs bugfix.
1157
1158 - new executable: para_filter. It combines para_mp3dec,
1159 para_oggdec and para_compress. It also adds a further filter
1160 type, wav, that just inserts a wave header at the desired point
1161 of the filter chain. All 'piping' is done in-memory (i.e. no
1162 read/write operations are used).
1163 - para_play: fix a stupid bug that caused it to hang under
1164 certain circumstances.
1165
1166 -------------------------------------------
1167 0.2.7 (2006-12-27) "transparent invariance"
1168 -------------------------------------------
1169
1170 Not many user-visible changes but a fair amount of internal improvements.
1171
1172 - The http sender buffers data if it can not be sent
1173 out immediately (because the socket is not writable). This
1174 should prevent para_server from shutting down the connection
1175 too early on a loaded network.
1176 - para_play also prebuffers data if it is told to start at a
1177 future time by the --start_time option.
1178 - The return of para_recv: It combines para_ortp_recv and
1179 para_http_recv. Use the --receiver option to switch between
1180 the two. para_recv builds without libortp, but contains
1181 only the http receiver in this case.
1182 - update to ortp 0.8.1. As this ortp release contains incompatible
1183 changes, para_recv-0.2.7 won't link against older ortp libs.
1184 - improved ortp timings.
1185 - use of gcc-extensions that #define away for non-gcc and
1186 gcc < 3.0.
1187
1188 -------------------------------------------
1189 0.2.6 (2005-10-29) "recursive compensation"
1190 -------------------------------------------
1191
1192 Transparent session encryption (uses openssl's Alleged RC4 cipher),
1193 the internal find command and several other improvements and cleanups.
1194
1195 - Encrypt the session if encryption is requested by the client
1196 (default for para_client 0.2.6). This is backwards
1197 compatible, so older clients can still connect to para_server
1198 0.2.6. Use the new client option --plain to request an
1199 uncrypted session (off by default, must be set to on in
1200 order to connect to para_server 0.2.x with 0 <= x <= 5).
1201 - para_server uses an internal function to locate audio files
1202 rather than calling find(1). The server option
1203 --mysql_audio_file_dir replaces --mysql_find_cmd.
1204 - documentation update
1205 - man pages
1206 - header file cleanup
1207 - para_client code cleanup
1208 - para_gui: faster display of output of display commands
1209
1210 ------------------------------------------
1211 0.2.5 (2005-10-13) "aggressive resolution"
1212 ------------------------------------------
1213
1214 This release adds internal senders, i.e. no more external programs are
1215 spawned for sending out the audio data. There are two different senders
1216 available: The http sender and the ortp sender (former para_send which
1217 is no longer needed).
1218
1219 The new sender code has a plugin-like design so it can be easily
1220 extended should there be be any future need for supporting another
1221 network streaming protocol. All senders are completely independent of
1222 each other. In particular, the http and the ortp sender can operate
1223 in parallel.
1224
1225 - new server command: sender to control senders at runtime.
1226 Read the output of "para_server -h" and "para_client help
1227 sender" for more information.
1228 - para_recv renamed to para_ortp_recv
1229 - new executable: para_http_recv, a simple command line
1230 http receiver.
1231 - major afs/mp3/ogg code simplifications due to internal
1232 senders.
1233 - ogg timing improvements
1234 - fix several minor memory leaks (found by valgrind)
1235 - empty stream definitions work again
1236 - com_ne(): ignore errors on remove
1237 - audiod: fix segfault on server restart
1238
1239 ---------------------------------------
1240 0.2.4 (2005-09-21) "toxic anticipation"
1241 ---------------------------------------
1242
1243 Several small improvements, fixes and the new grab command.
1244
1245 - audiod:
1246 - new command: "grab" to grab the output of the stream reader
1247 or any filters. Read the output of "para_audioc help grab"
1248 for more information.
1249 - fix memory leak
1250 - code cleanup
1251 - audioc: new command line option: --bufsize to specify a
1252 buffer size different from the default size 8192.
1253 - improved error diagnostics for para_play.
1254 - new configure option: --enable-ssldir so search for openssl in
1255 non-standard places
1256 - sdl_gui: Make it look nice again for 1024x768
1257 - server: report total size of memory allocated with sbrk by malloc,
1258 new command line option: --announce_time
1259
1260 -----------------------------------------
1261 0.2.3 (2005-09-01) "hydrophilic movement"
1262 -----------------------------------------
1263
1264 Two new executables and major feature enhancements.
1265
1266 - audiod filters: It is now possible to specify arbitrary many
1267 (including none) filters for each supported audio
1268 format. This can be used e.g. for normalizing volume,
1269 transforming or grabbing the audio stream, or for using
1270 visualizers. Read the output of "para_audiod -h" for the
1271 syntax of the new --filter_cmd option.
1272 - new executable: para_play, a tiny alsa player. It
1273 can play wave files or raw pcm (16 bit little endian)
1274 from stdin.
1275 - new executable: para_compress, a dynamic range compressor
1276 intended to keep audio output at a consistent volume. Derived
1277 from [AudioCompress](http://trikuare.cx/code/AudioCompress.html).
1278 - audiod: New option: --stream_delay. This can be used in
1279 a local network to syncronize the audio output of all
1280 clients that play the same stream.
1281
1282 ------------------------------------------
1283 0.2.2 (2005-08-19) "tangential excitation"
1284 ------------------------------------------
1285
1286 Mostly internal changes in this release, but also some new commands
1287 for the mysql database tool.
1288
1289 - cleanup exec.c, fix para_exec bug
1290 - compile time loglevel (log messages below the given level
1291 won't be compiled in, which reduces the size of the
1292 resulting binaries)
1293 - new log macros that shorten the size of the source code.
1294 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
1295 to send only zeros. With this workaround, para_audioc works
1296 again.
1297 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
1298 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
1299 (new entry), "snp" (set numplayed). Read the manual for more
1300 information.
1301
1302 ---------------------------------------
1303 0.2.1 (2005-08-15) "surreal experience"
1304 ---------------------------------------
1305
1306 Here comes paraslash-0.2.1. It contains a couple of new features and,
1307 surprise, only minor bug fixes.
1308
1309 - kill noisy mp3 debug message
1310 - cleanup of the build system
1311 - para_server and para_client directly use the crypto routines
1312 of the openssl library rather than invoking the openssl command
1313 line utitlity
1314 - server/audiod: new option --user to switch to the given user
1315 when invoked as root. Read the output of "para_server -h" for
1316 more information.
1317 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
1318 status. Default: "para_audioc stat"
1319 - sdl_gui: new option --pic_cmd to be used to download the picture.
1320 Default: "para_client pic"
1321 - audiod: 5 slots ought to be enough for everybody
1322 - audiod: new status item: Uptime, kill hup command
1323
1324 ------------------------------------------
1325 0.2.0 (2005-08-06) "distributed diffusion"
1326 ------------------------------------------
1327
1328 After several month of increased development activity, paraslash-0.2.0
1329 has arrived. It contains many new features and is much more
1330 self-contained than the old 0.1.x series. Enjoy!
1331
1332 - para_server: fix hang on song change and crash on sighup.
1333 Speed up mysql queries. The DIR_LIKE macro is gone.
1334 - new executables: para_audiod, the local audio daemon that
1335 starts playback (uses SCM_CREDENTIALS socket magic) and
1336 para_audioc, the corresponding client.
1337 - new executables: para_mp3dec/para_oggdec, two really teensy
1338 decoders. para_mp3dec is based on libmad, para_oggdec requires
1339 libvorbisfile.
1340 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
1341 they are now called para_send and para_recv respectively.
1342 - documentation updates
1343 - para_gui is themable. For now there is the default theme that
1344 looks as before and the simple theme: blue and easy.
1345 - gui: audio streaming is now handled by audiod. Time display shows
1346 playback time rather than streaming time
1347 - slider: update to libzmw-0.2.0
1348 - para_krell: fix crash on server shutdown
1349 - switch from gzip to bzip2
1350
1351 ----------------------------------------
1352 0.1.7 (2005-04-18) "melting penetration"
1353 ----------------------------------------
1354
1355 The main change in this release is clearly the oggvorbis rewrite,
1356 but there are also lots of smaller changes. If you intend to use both
1357 the mp3 and the ogg plugin, it is recommended to use software mixing,
1358 e.g. the dmix plugin which is provided by ALSA.
1359
1360 - new executables: para_ovsend and para_ovrecv for sending/receiving
1361 oggvorbis files via rtp. Requires the open rtp library. Get it at
1362 http://www.linphone.org/ortp/
1363 - rewrite of the ogg_vorbis core code
1364 - configure detects libzmw and, if detected, includes
1365 para_slider to the list of binaries to be built by make
1366 - server stream writers read from their associated fifo rather
1367 than from stdin
1368 - slider: two new sliders, lastplayed and numplayed
1369 - fix nasty double free bug which caused random segfaults in case of
1370 mp3 files with invalid header information
1371 - gui: new command line option: --stream_timeout=seconds to
1372 deactivate a slot if it is idle for that many seconds (default=`5')
1373 - diffstats
1374
1375 ---------------------------------------
1376 0.1.6 (2005-03-05) "asymptotic balance"
1377 ---------------------------------------
1378
1379 Only little user-visible changes in this release. Mainly bugfixes and
1380 core code cleanup. This is probably the most stable version ever if you
1381 stick to mp3...
1382
1383 - fix several memory leaks
1384 - rename default name of mysql database from "music" to "paraslash".
1385 Use para_server's --mysql_database option if you do not want to
1386 rename your old database.
1387 - rework ogg vorbis code
1388 - make update command work on mysql servers with LOCAL_INFILE
1389 disabled
1390 - gui: improved stream I/O (slots)
1391 - simplified audio format API
1392 - para_pob_ogg is gone
1393
1394 ------------------------------------
1395 0.1.5 (2004-12-31) "opaque eternity"
1396 ------------------------------------
1397
1398 Let's slide gently into the new year.
1399
1400 - new: para_slider (not built automatically, type "make
1401 para_slider" to build). A toy for those who always felt that
1402 creating stream definitions is difficult. See screenshots,
1403 README and FEATURES for more info.
1404 - improved signal handling. Fixes server segfault on SIGHUP
1405 for linux kernels newer than Aug 24 2004 and makes para_gui
1406 race-free.
1407 - reload database tool on SIGHUP
1408 - improved help message for sl
1409 - do not log "broken pipe" messages as errors. They are
1410 perfectly ok.
1411 - fix wrong error message on permission errors
1412
1413 -----------------------------------------
1414 0.1.4 (2004-12-19) "tunneling transition"
1415 -----------------------------------------
1416
1417 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1418 Hopefully, most of them got wiped out with this release. Some
1419 enhancements went also in.
1420
1421 - improved error diagnostics for all commands
1422 - stradd/picadd: overwrite previous contents if entry already
1423 exists, rather than returning errors
1424 - stradd: use current stream if invoked without args
1425 - faster (and hopefully more stable) ogg-vorbis handling
1426 - para_krell: reap children to avoid zombie-flooding in case
1427 no server is running
1428 - si: report also server pid
1429 - server: don't busy-loop if dbtool reports only invalid files.
1430 - gui: CTRL+C works again, fix stream_read command line option
1431 - fix pic_add, hist
1432 - fix mysql dbtool startup in case no database exists
1433 - many small fixes and cleanups
1434
1435 ---------------------------------------
1436 0.1.3: (2004-12-10) "vanishing inertia"
1437 ---------------------------------------
1438
1439 Starting from this release, the database tools are integrated in the
1440 server binary. This decreases server startup time, reduces code size
1441 and speeds up database commands. However, the layout of the underlying
1442 mysql database changed only slightly and 0.1.3 should be backwards
1443 compatible in that respect.
1444
1445 Visible changes:
1446
1447 - If mysql is not detected at compile time, or fails to init
1448 at runtime, fall back to the dopey database tool which should
1449 always work.
1450 - para_dbtool and dbtool.conf are gone. All mysql specific
1451 options are read from server.conf and are prefixed by 'mysql_'.
1452 - new command: cdt (change database tool)
1453 - new command line option: dbtool (choose startup database tool)
1454 - The name of current stream is now stored in the database,
1455 so paraslash remembers its current stream when restarted.
1456 - new command: csp (change stream and play)
1457 - para_gui also reports current database tool and server uptime
1458
1459 -------------------------------------------
1460 0.1.2: (2004-11-28) "spherical fluctuation"
1461 -------------------------------------------
1462
1463 Point release before the big dbtool changes go in.
1464
1465 - dbtool: rename ca to cam (copy all meta data). It now also
1466 copies numplayed and lastplayed time as well as the picture
1467 id.
1468 - fix endless-loop-bug caused by mp3 files with invalid header
1469
1470 -----------------------------------------
1471 0.1.1: (2004-11-05) "floating atmosphere"
1472 -----------------------------------------
1473
1474 - gkrellm plugin
1475 - new dbtool command: mbox. Browse your sound-file collection
1476 with your favorite mail reader.
1477 - several small fixes
1478
1479 -------------------------------------
1480 0.1.0: (2004-10-22) "rotating cortex"
1481 -------------------------------------
1482
1483 - fix logging bug for loglevel > VERBOSE
1484 - fix skip command
1485 - correct timings for vbr mp3s
1486 - modular audio format support
1487 - ogg-vorbis support (experimental)
1488 - new server option: autoplay
1489
1490 -----------------------------------------
1491 0.0.99: (2004-07-25) "harmonic deviation"
1492 -----------------------------------------
1493
1494 - rename projectname from icc to paraslash (play, archive, rate
1495 and stream large audio sets happily)
1496 - paraslash is no longer restricted to one particular audio
1497 streaming software
1498 - new dbtool commands (stradd, strq, strdel) for easy stream
1499 managment w/o configuration file. That obsoletes stream_defs
1500 file/config option for dbtool.
1501 - picadd accepts jpeg data from stdin
1502 - new server commands: ps (select previous stream), sc (song change)
1503 - new default pictures for sdl_gui
1504 - gui: new key_map option for binding commands and internal
1505 functions to arbitrary keys, nice help screen, rip out
1506 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1507 show silly logo on startup
1508 - new executables: para_fade for fading volume, para_dbadm for
1509 manipulating attributes
1510 - cdb adds _all_ tables to mysql database
1511 - revised and beautified documentation
1512 - sample dbtool rewritten in C
1513 - autoconf
1514
1515 ---------------------------------------------
1516 0.0.98: (2003-12-26) "incremental smoothness"
