5 0.7.2 (2023-03-08) "optical friction"
6 -------------------------------------
8 The improved error reporting of afs commands and the two new options
9 for the sleep subcommand of para_mixer are the most prominent features
10 of this minor release. The bulk of the changes are cleanups of the
11 afs and net subsystems, which should both have no user-visible impact.
13 - A major cleanup of the audio file selector.
14 - The client no longer prints error messages from afs commands to
16 - The sleep subcommand of para_mixer gained two options to control
17 the startup mood and the time period before fade-out starts. A bunch
18 of further improvements for this subcommand went in as well.
19 - Minor cleanup of the net subsystem.
20 - The openssl specific code now employs the EVP API to compute hashes.
21 It should compile without warnings against openssl-3.
22 - The deprecated syntax for specifying negative offsets in the argument
23 to the "ff" server command has been removed.

30 0.7.1 (2022-10-03) "digital spindrift"
31 --------------------------------------
33 The two new ll commands and the internal mp4ff library are the most
34 user-visible changes of this release. On top of that there are two
35 core changes which aim to improve the robustness of the code but which
36 are otherwise invisible: the switch from select(2) to poll(2) and the
37 revised memory allocation API which checks for integer overflows. The
38 release also comes with a slight change to the build system and the
39 usual mix of bug fixes and minor improvements not mentioned here.
41 - The autogen.sh script now only creates the autoconf specific files
42 but no longer runs configure, make and the test suite.
43 - A stripped down copy of the discontinued libmp4ff library has become
44 part of the paraslash code base. As a result it is no longer necessary
45 to install faad from source to get support for aac/m4a files. The
46 faad decoder package must still be installed.
47 - The log level of the running daemon can now be changed with the
48 new ll command. It is available for para_server and para_audiod.
49 - All calls to select(2) have been replaced by calls to poll(2)
50 to avoid known shortcomings of the select API.
51 - All allocation functions now check for integer overflow. Since this
52 requires support from the compiler, the oldest supported gcc version
53 has been bumped to gcc-5.4 (released in 2015).

60 0.7.0 (2022-03-12) "seismic orbit"
61 ----------------------------------
63 The major incompatible change which requires to bump the major version
64 is the switch from sha1 to sha256, see below for details. However,
65 there are many other improvements, the usual amount of bug fixes and
66 a couple of new features.
68 - Starting with paraslash-0.7.0, the sha256 hash value of each known
69 audio file is stored in the database while older versions employed the
70 sha1 hash algorithm which has been considered insecure since 2005
71 and should no longer be used today. The switch from sha1 to sha256
72 requires users to upgrade their database using the new para_upgrade_db
73 program, followed by re-adding all files to recompute the hashes. With
74 this approach all metadata stored in the database (last played date,
75 num played value, moods, playlists, attributes etc.) are kept. An
76 simpler alternative is to start over from scratch by running the
77 "init" command but this will lose these metadata.
78 - Server and client now hash the session keys with sha256 rather
79 than sha1 during the initial handshake. This feature is optional and
80 backwards compatible: old clients can still connect to a new server
81 (using sha1). Also new clients can connect to an old server (again
83 - The new "duration" keyword of the mood grammar makes it possible to
84 impose a constraint on the duration of the admissible files.
85 - The long deprecated version 1 mood syntax is no longer supported.
86 - Paraslash writers handle early end-of-file more gracefully.
87 - The alsa writer no longer warns about spurious underruns.
88 - The score formula of the audio file selector has been reworked.
89 - Cleanups of the doubly linked lists code.
90 - New option for configure: --enable-ubsan to detect and report undefined
92 - The "tasks" server command has been removed.
93 - The fancy new logo and a minor overhaul of the web pages.

103 This point release contains a fair number of fixes but no new features.
104 This marks the end of the 0.6 development, although paraslash-0.6 will
105 still be supported for some time and subsequent maintenance releases
108 - The udp sender no longer crashes when empty chunks are encountered.
109 - Fix a double-free bug in the exit path of the server.
110 - The "jmp" command now errors out when given a negative percentage.
111 - A fix for a bug in para_afh which triggered on the attempt to modify
112 the tags of an invalid mp4 file.
113 - A memory leak in para_afh has been fixed.
114 - The udp sender no longer sends multiple EOF packets.

126 This release contains a few important fixes which have accumulated in
127 the maint branch. The paraslash-0.5.x series has now reached its end
128 of life and will no longer be supported. All users should upgrade to
129 a more recent version at this point.
131 - Fix an issue with the bash completion script.
132 - Initialize the random seed also when using libgrypt.

141 0.6.3 (2021-02-18) "generalized activity"
142 -----------------------------------------
144 It has been a while since the last release, but paraslash-0.6.3
145 finally has arrived. It contains a fair number of improvements,
146 features and fixes all over the place.
148 - The ff command now accepts a negative argument to instruct the
149 virtual streaming system to jump backwards in the current audio
150 stream. The old syntax (e.g., "ff 30-") is still supported but it
151 is deprecated and no longer documented. The compatibility code is
152 sheduled for removal after 0.7.0.
153 - para_afh: New option: --preserve to reset the modification time to
154 the value of the original file after meta data modification.
155 - Overhaul of the compress filter code. The refined algorithm should
156 reduce clipping. The meaning of --aggressiveness has changed, see the
157 updated and extended documentation of the compress filter for details.
158 - Cleanup of the audio format handler code.
159 - We now build the tree using the .ONESHELL feature of GNU make,
160 which results in a significant speedup.
161 - Two robustness fixes for FreeBSD.
162 - para_client now supports RFC4716 private keys as generated with
163 ssh-keygen -m RFC4716. In fact, this key format has been made the
164 default, and the former PEM keys will be depreciated at some point.
165 - The ogg audio format handlers learned to detect holes and now report
166 the correct duration also if ogg pages are missing in the file. This
167 affects ogg/vorbis ogg/speex and ogg/opus.
168 - Robustness improvements for para_mixer.
169 - A fix for an old bug that could cause the server to crash or report
170 garbage in its status output.
171 - New para_play option: --end-of-playlist
172 - Streaming m4a files over udp has been improved.

179 0.6.2 (2018-06-30) "elastic diversity"
180 --------------------------------------
182 The main new feature of this release is the --listen-address option
183 for para_server and para_audiod. But there are also a large number of
184 small improvements and bug fixes all over the place. The user-visible
187 - para_gui no longer waits up to one second to update the screen when
188 the geometry of the terminal changes.
189 - Minor documentation improvements.
190 - Improvements to the crypto subsystem.
191 - The server subcommand "task" has been deprecated. It still works,
192 but prints nothing. It will be removed in the next major release.
193 - Server log output is now serialized, avoiding issues with partial
195 - It is now possible to switch to a different afs database by changing
196 the server configuration and sending SIGHUP to the server process.
197 - New server options: --listen--address, --http-listen-address and
198 --dccp-listen-address. These options restrict the set of listening
199 addresses of the TCP and DCCP sockets of the server process.
200 - The help commands of server, audiod, play now support --long. By default,
201 the short help is shown.
202 - The code which merges the command line options with the config file
203 options has been consolidated.
204 - If the current audio file is renamed, the status items are now updated
206 - After the server process received SIGHUP, changes to the current audio
207 file did not trigger an update of the status items. This has been fixed.

214 0.6.1 (2017-09-23) "segmented iteration"
215 ----------------------------------------
217 The highlight of this release is the version 2 mood parser. But there
218 is a lot more than that, as summarized in the list below. And of
219 course we have many small usability improvements and bug fixes not
222 - A more intuitive syntax for moods ("version 2 moods"). The
223 traditional version 1 moods are still supported but are deprecated
224 now. Removal of the version 1 mood parser is scheduled for the next
226 - Flex and bison are now required to build para_server.
227 - New sort order for the ls command: -s=h sorts the ls output by hash
228 value of the audio file.
229 - autogen.sh now runs the test suite after a successful build.
230 - The contents of overview.pdf have been integrated into the user
232 - Fixed sized audio format headers for ogg/opus streams.
233 - The doxygen source browser has been disabled temporarily. The
234 API reference is still online, though.
235 - Overhaul of the source code documentation.
236 - The deprecated --full-path option of the ls command has been
237 removed. It was a no-op since 0.6.0.
238 - The wma decoder has been cleaned up and its bitstream API made
240 - The image/lyrics ID status items of the current audio file are now
241 updated on changes. This affects para_gui, which used to report the

269 A couple of fixes for serious old bugs have accummulated in the maint
270 branch since paraslash-0.5.7 was released nine months ago. So here
271 is another 0.5.x release. As usual, all commits in the maint branch
272 have been merged into master, so the upcoming paraslash-0.6.1 also

280 0.6.0 (2017-04-28) "fuzzy flux"
281 -------------------------------
283 The highlights of this release are the conversion of all option parsers
284 to the lopsub library and the improved AAC support. But there are
285 many other user-visible changes all over the place. Also a lot of
286 old cruft has been removed, leading to incompatible changes. Hence
287 the new major version number.
289 - Support for Mac OS X has been removed.
290 - On Linux systems, glibc-2.17 or newer is required to build the
292 - Support for RSA public keys in ASN format (as generated by openssl
293 genrsa) has been removed. These keys have been deprecated since
294 2011, so users should have long switched to keys generated with
296 - If libgcrypt is used as the crypto library, we now require version
297 1.5.0 (released in 2011) or later.
298 - The insecure RC4 stream cipher has been removed. It was superseded
299 by aes_ctr128 three years ago but the RC4 code had been kept for
300 backwards compatibility.
301 - On Linux, abstract unix domain sockets are used unconditionally.
302 - The "install" target no longer strips executables, the new
303 install-strip target can be used to get the old behaviour.
304 - The clean targets have been renamed: clean2 is gone, and the new
305 mostlyclean removes only the executables and object files.
306 - New target: check (identical to test).
307 - The DESTDIR make variable is honored to prepend a path to the
308 installation directory. This feature is orthogonal to the --prefix
310 - Minor WMA cleanups.
311 - The aac audio format handler has been rewritten to use the mp4ff library.
312 See the manual for how to install the library on your system.
313 - New status item: max_chunk_size. The value is stored in a previously
314 unused field of the afhi object of the aft table. Although backwards
315 compatible, users are encouraged to re-add m4a files to populate
317 - No more chunk tables for aac. Chunk boundaries are determined
318 dynamically at stream time.
319 - Release and master branch tarballs are now compressed with xz rather
321 - The lopsub package is required to install the paraslash package.
322 Gengetopt is no longer needed.
323 - make dep is gone. Dependencies have been created automatically for
324 a long time and it was never necessary to run make dep manually.
325 - para_gui lost its --timeout option.
326 - Most manual pages have been extended to include an overall
327 description of the command.
328 - The --stream-delay option of para_audiod has been removed. It had
329 been a no-op for many years.
330 - The deprecated --path option of the server ls command has been
331 removed. The command now prints full paths by default, making
332 --full-path a no-op. Hence --full-path has been depreacted and is
333 scheduled for removal in v0.6.1.
334 - It is now possible to use 'CFLAGS' to override the default compiler
336 - para_fade has been renamed to para_mixer. The four modes of operation
337 (set, fade, snooze, sleep) are implemented as subcommands of the
339 - The sleep subcommand of para_mixer (former sleep mode of para_fade)
340 lost its --wake-hour and --wake-min options in favor of the new
341 --wake-time option which also accepts relative wakeup times like

355 Mostly a bug fix release, and a bunch of internal improvements.
356 The only user-visible changes are the sanity checks for the touch
357 command and the new options to the ls command.
359 - Speedup of the base64 decoder.
360 - One of the two source browsers has been removed from the web pages.
361 The doxygen API reference still contains an HTML version of each
363 - Two race conditions in para_server have been fixed.

365 the ls command for details.
366 - The openssl code has been adjusted to work also with openssl-1.1.
367 - The wma decoder and audio format handler now correctly decodes
368 files with unusual block sizes.
369 - We now compile with -Wformat-signedness if possible.
370 - The touch command now refuses to set an invalid image or lyrics ID.
371 - New section on contributing for the user manual.
372 - Major simplification of the error subsystem.

379 0.4.14 (2016-12-31) "branching oscillation"
380 -------------------------------------------
382 Many fixes for nasty bugs have accumulated over the years since 0.4.13
383 was released in 2013. This release contains all of them. It is the
384 last v0.4.x release, so v0.4.x is now end of life. The maint branch
385 of the git repository has been forwarded to v0.5.7 and will start to
386 receive important fixes for 0.5.x, which is now in maintenance mode.
388 - Fix for the "double encryption bug" with gcrypt, which caused
389 garbage to be sent to stat clients.
390 - The "prev" command of para_play now works as expected.
391 - Invalid parameters for the begin and end chunk no longer cause
392 the afh receiver of para_recv to segfault.
393 - A fix for an assertion that triggered in the FEC slice setup code.
394 - Closing the terminal with a running para_gui causes the process to
395 die, rather than using 100% of CPU time.
396 - para_gui no longer shows stale information about the previous
398 - A fix for a bug in the fec decoder which caused aborts if the buffer
400 - The assertion in the buffer tree code no longer triggers.
401 - The "afs_event: table moods, event 0: key already exists in rbtree"
402 error no longer occurs on attribute changes.
403 - A NULL pointer dereference in com_sender() has been fixed.
404 - The -i option of lsatt works as advertised.

416 lets it modify the meta tags of the given audio file(s). This feature
417 is supported for all audio formats. Many small cleanups and bug fixes
418 not mentioned here have accumulated and are also part of the release.
420 - para_afh learned to modify meta tags of mp3 wma ogg spx
422 - afs commands propagate error codes to the client.

445 - On Linux systems, local sockets are now created in the
446 abstract name space by default. This allows to get rid of
447 the socket specials in /var/paraslash.
448 - The --user-allow option of para_audiod now accepts also
449 usernames rather than only user IDs.
450 - New autoconf macros to avoid duplication in configure.ac.
451 - Status items (as shown by para_gui) are updated correctly
452 when the meta information of the current audio changes.
453 - para_server and para_audiod no longer refuse to start in
454 the background if no log file is given. Instead, all log
455 messages go to /dev/null in this case.
457 - New syntax for the -l and -s options of the ls command.
458 These options should now be specified as -l=v rather than
459 -lv, for example. The old syntax still works, but support
460 will be dropped in v0.6.0.

513 The new sync filter, the AES_CTR128 stream cipher and the overhauled
514 network code are the highlights of this release. It also includes a
515 fair number of smaller fixes and improvements not mentioned here.
517 - The new sync filter synchronizes playback between multiple
519 - Connections between para_server and para_client are now
520 encrypted by means of AES rather than RC4 if both sides
521 support it. RC4 is still available as a fallback. This
522 feature is fully transparent, i.e. no command line options
523 are necessary, and a client linked against openssl can
524 speak with a server linked against libgcrypt and vice versa.
525 - Major cleanup of the networking subsystem.
526 - Improvements to para_fade: the new set mode, multi-channel
527 initial volumes, better error logging.
528 - The man pages of para_audiod, para_filter, para_recv, and
529 para_write contain the relevant options for receivers, filters,
530 writers. This broke in 0.5.0.
531 - ogg/vorbis latency improvements.

547 - Buffer tree robustness improvements.
548 - Cleanup of the mood subsystem.
549 - Fixes and cleanups for the flac decoder.
550 - Latency improvements for the ogg/opus decoder.
551 - Crypto support is now optional. On systems without
552 openssl/gcrypt, the build succeeds but para_server,
553 para_audiod, para_client won't be built.
554 - The build system now works for cross-compile setups.
555 - The dependency tree has been flattened, which speeds up
556 builds and avoids to recreate the man pages on every change.
557 - The error code helper has been rewritten from perl to C,
558 which further improves build time.
559 - Many small bugs in the build system have been identified

566 ----------------------------------------
567 0.5.0 (2013-08-23) "invertible validity"
568 ----------------------------------------
570 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
572 - The sideband compatibility code has been removed, hence
573 sideband connections (introduced in 0.4.11) are now mandatory.
574 - Addblob commands can produce output.
575 - The stat command no longer sends garbage when para_server was
576 compiled against libgcrypt.
577 - Dependencies for gengetopt files are computed automatically.
578 This eliminates a constant source of build bugs.
579 - The setatt command now accepts file name patterns rather than only
581 - overview.pdf is now based on dia, a simple diagram creation program.
582 The new version is much more detailed and contains descriptions of
583 the various programs of the paraslash package.
584 - The separator of all multi-word options has been changed from
585 underscore to dash. For example --log_color becomes --log-color.
586 - Overhauled web pages and the new logo.

592 --------------------------------------
593 0.4.13 (2013-07-29) "spectral gravity"
594 --------------------------------------
596 One more 0.4.x release before the API-breaking changes for 0.5.0 go
597 in. The main features of this release are the ogg/opus audio format,
598 and UTF-8 support, but it includes also tons of other improvements
599 and fixes all over the place.
601 - New audio format: ogg/opus.
602 - UTF8 support for para_gui and the mp3 audio format handler.
603 - Scheduler improvements and fixes.
604 - The obsolete gettimeofday() function has been replaced
605 by clock_gettime() on systems which support it.
606 - Speed and usability improvements for para_gui.
607 - para_client now restores the fd flags of stdin and stdout
609 - Improved manual pages.
610 - Consistent version strings for all executables.
611 - Reduced dependencies on generated files result in fewer
612 recompilations on changes.
613 - Performance improvements for the compress filter.
614 - Improved downloads web page.
616 -----------------------------------------
617 0.4.12 (2012-12-20) "volatile relativity"
618 -----------------------------------------
619 The new command line player, the resample filter, ALSA support for
620 para_fade, and the improved build system are the highlights of this
621 release which probably marks the end of the 0.4.x series.
623 - The afh receiver and the para_play executable.
624 - The resample filter: A sample rate converter based on
626 - The "versions" directory has been removed from the master
627 branch. The tarballs of the old releases are now available
628 in the new "releases" branch.
629 - Overhaul of the build system: All generated files are now
630 written to the "build" directory.
631 - The modular mixer API and the alsa mixer.
632 - Minor fixes for the osx writer.
634 --------------------------------------
635 0.4.11 (2012-07-20) "mutual diversity"
636 --------------------------------------
638 The major feature in this release is the new sideband API for
639 client-server communication. This API will be used exclusively starting
640 with 0.5.0, which breaks backward compatibility but allows to get rid
641 of quite some compatibility code. Other noteworthy changes include
642 decoder latency improvements and a long-standing bug fix for the
645 - Sideband connections: If both para_server and para_client
646 support this feature, data is sent as a multiplexed stream.
647 - The --no_default_filters option of para_filter has been
649 - Several fixes and latency improvements to various decoders.
650 - The ALSA writer now limits the prebuffer time to 500ms.
651 - Documentation improvements.
652 - Overhaul of the command_util.sh script.
653 - Fixes for some minor problems found by the clang analyzer.
654 - Compiles (almost) without warnings on gcc-3.
655 - Robustness improvements of the buffer tree code.
657 ------------------------------------------
658 0.4.10 (2012-03-30) "heterogeneous vacuum"
659 ------------------------------------------
661 Nothing earth-shaking in this release, but quite a few usability
662 improvements and the usual mix of cleanups and fixes.
664 - The --no_default_filters option of para_filter has been
665 deprecated. It still works but has no effect and will be
666 removed in the next version.
667 - para_gui now prints also the stderr output of the executing
668 command in the bottom window.
669 - Cleanup and consolidation of the various wrappers for
670 write(), writev(), send() and friends.
671 - The obscure error messages on mmap() failures have been
672 replaced by meaningful messages. This affects mainly
674 - para_audioc: Cleanups and memory leak fixes.
675 - Test 0004-server no longer fails if para_server is not
677 - New configure options: --with-id3tag-{headers,libs}.
679 -------------------------------------
680 0.4.9 (2011-12-06) "hybrid causality"
681 -------------------------------------
683 Support for another audio format, interactive mode for para_client
684 and para_audiod and many small improvements/fixes all over the place.
686 - Support for flac, the free lossless audio codec.
687 - Fix for an endless loop in the mp3 decoder for certain
689 - When executed without specifying a command, para_client
690 and para_audioc start an interactive shell (requires
691 libreadline being installed). The interactive mode offers
692 full tab completion and command line history.
693 - autogen.sh now detects a distcc setup and adjusts the
694 parameter for the -j option of make accordingly.
695 - Shared memory areas are no longer restricted to 64K. We now
696 detect the maximal size of a shared memory area at runtime.
697 - cleanup of the internal uptime API.
698 - para_server prefaults the mmapped audio file to avoid
699 delays on slow media.
700 - A new test for the test-suite that exercises the
701 communication between para_server and para_audiod.
702 - The alsa writer eats up less CPU cycles when configured to
704 - Simplified and unified receiver code.
706 - Commands which print a list of matching audio files now
707 emit a meaningful error message if no audio file matched the
710 --------------------------------------
711 0.4.8 (2011-08-19) "nested assignment"
712 --------------------------------------
714 Gcrypt support, the overhauled osx writer and regex format specifiers
715 are the highlights of this release.
717 - support for libgcrypt as a drop-in replacement for openssl.
718 Run configure --enable-cryptolib=gcrypt to link against
719 libgcrypt. The two crypto implementations are compatible to
720 each other, i.e. a para_client executable linked against
721 gcrypt can connect to para_server linked against libssl
723 - Rewrite of the osx writer (output plugin for Mac OS).
724 - audiod: The format specifier for receivers, filters and
725 writers is now treated as a regular expression. This allows
726 to replace 5 lines in the config file (one for each audio
727 format) by one single line. See the manual for details.
728 - The \*.cmdline.[ch] files are no longer contained in the released
729 tarballs. This reduces the size of the tarballs but requires
730 gengetopt to build the tarball.
731 - Compiles cleanly also with llvm/clang.
732 - Corrupt mp3 files are handled more gracefully.
733 - The alsa writer uses poll fds instead of computing timeouts.
734 - Cleanup of the generic writer API.
735 - sched: Optimized zero timeouts.
736 - vss timeout cleanups.
737 - oggdec fixes and improvements.
739 --------------------------------------
740 0.4.7 (2011-06-01) "infinite rollback"
741 --------------------------------------
743 The new ao writer, support for ssh RSA keys and a couple of other
746 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
747 platforms through the libao audio library.
748 - Support for RSA keys generated with ssh-keygen.
749 - configure: improved options for ogg/vorbis/speex.
750 - The git version reported by --version always matches HEAD.
751 - The autogen script detects the number of processors and
752 runs a parallel make if possible.
753 - Major cleanup of the crypto API.
754 - Documentation updates.
756 ------------------------------------------
757 0.4.6 (2011-03-31) "deterministic entropy"
758 ------------------------------------------
760 Lots of ogg/vorbis improvements, the new test suite, enhancements
761 for para_gui and a fair amount of other bug fixes.
763 - For DCCP/OGG streams the audio file header is only sent once
764 at the beginning of the stream rather than periodically
765 every five seconds. This reduces network traffic and the
767 - The vorbis comment header is replaced by an empty dummy header
768 before the header is sent over the network. This also results in
769 less network traffic and smaller FEC groups.
770 - The new "test" make target allows to perform some sanity checks prior
771 to installing the package.
772 - ogg timing fixes and performance improvements
773 - Scheduler improvements
774 - Proper exit codes for para_write
775 - para_gui: New option --theme to select a startup theme. Several
776 other improvements and fixes.
777 - aacdec error message cleanups
778 - simplified color error handling
780 --------------------------------------------
781 0.4.5 (2010-12-17) "symmetric randomization"
782 --------------------------------------------
784 Bug fixes, internal cleanups and variable-sized FEC slices.
786 - Contains a fix for an invalid-free-bug in the ogg audio format
788 - Switching off the DCCP sender works again.
789 - para_audiod handles crashes of para_server more robustly.
790 - Internal scheduler and writer cleanups.
791 - Reduced latency due to variable-sized FEC slices.
792 - Improved documentation and error diagnostics.
793 - The build of para_server is now optional, allowing the build
794 to succeed in case libosl is not installed.
796 ------------------------------------------
797 0.4.4 (2010-08-06) "persistent regularity"
798 ------------------------------------------
800 Support for yet another audio format, para_write improvements and
803 - Support for the speex codec.
804 - Support for sample formats other than 16 bit little endian.
805 - error2.h is now created by a perl script which speeds up configure
807 - Fix a bug in the aac decoder which could lead to segfaults in
808 para_filter/para_audiod.
809 - Fixes for autoconf-2.66.
811 ----------------------------------------
812 0.4.3 (2010-07-05) "imaginary radiation"
813 ----------------------------------------
815 Many improvements for the DCCP and the UDP transport, the new user
816 manual and the usual mix of bug fixes and internal improvements.
818 - FEC support for the DCCP sender (Gerrit Renker). The new
819 --dccp_max_slice_size, --dccp_data_slices_per_group and
820 --dccp_slices_per_group options can be used to set the FEC
821 parameters for the DCCP transport.
822 - DNS lookups for UDP targets (Gerrit Renker).
823 - The new user manual replaces the README, README.afs, REQUIREMENTS
824 and INSTALL documents.
825 - Fix an end-of-file detection bug in the oggdec filter.
826 - The new nonblock API.
827 - Both options of the oggdec filter have been removed.
828 - New debug mode for the internal scheduler.
830 ------------------------------------------
831 0.4.2 (2010-04-23) "associative expansion"
832 ------------------------------------------
834 It's been some time since the last release, but finally here is
835 paraslash-0.4.2. The bulk of the changes comes from the new buffer
836 tree API, but there are changes all over the tree. Mainly performance
837 and usability improvements, but also quite some bug fixes.
839 - The new buffer tree API.
840 - DCCP: Support for CCID negotiation (Gerrit Renker).
841 - UDP robustness fixes.
842 - The --bufsize option for mp3dec is gone as it no longer makes sense
843 for the new buffer tree API.
844 - Fix audible buffer underruns for wma streams.
845 - The alsa writer no longer prints meaningless underrun durations.
846 - audiod: Defaults work also for udp streams. If no filter is
847 given for an audio format that is received via upd, fecdec is
848 automatically added as the first filter (along with the decoder).
850 ---------------------------------------
851 0.4.1 (2009-12-22) "concurrent horizon"
852 ---------------------------------------
854 Support for another audio format, minor feature enhancements and lots of bug
855 fixes. All fixes that have been accumulated in the maint branch (in particular
856 those mentionened in the 0.3.6 release notes) appear in this release as well.
859 - new afh option: --human to activate human-readable output.
860 - new server/audiod option: --log-timing to print timing information.
861 - build system improvements.
862 - source code documentation updates.
864 -------------------------------------
865 0.3.6 (2009-12-07) "cubic continuity"
866 -------------------------------------
868 Quite a few bugs have been found and fixed since 0.3.5, so here's
869 another 0.3.x release. No new features.
871 - Always check return value of malloc().
872 - ogg vorbis/FEC: Do not write garbage after the audio file header.
873 - exit if root privileges could not be dropped.
874 - FEC: Fix computation of extra slices.
875 - oss: Fix check for empty input buffer.
876 - Avoid buffer underruns due to filter chain output buffer constraints.
877 - server: Fix assignment of afs_pid.
878 - Don't panic if the afs database contains unknown audio formats.
879 - http/dccp: Do not send the audio file header twice.
880 - FEC: Timing improvements.
882 ----------------------------------------------
883 0.4.0 (2009-11-10) "simultaneous independence"
884 ----------------------------------------------
886 Two significant changes which require the new version number: The
887 improved authentication dialog and the fact that the database code
888 has been moved to a library, libosl. To use the new version, you have
889 to generate new RSA keys, see INSTALL for details. A shell script is
890 provided for conversion of the 0.3 database to the new 0.4 format.
892 - stronger crypto for client authentication
893 - the database code has been moved to a library
894 - improved status item handling
895 - cleanup of the build system
896 - The "-V" option now also prints the git version
897 - the new parser-friendly listing mode for the ls and stat commands
898 - mandatory rc4 encryption
899 - major audio format handler cleanups
900 - (id3,...) tags are no longer stored as a combined string in the database
901 - new mood methods: artist_matches, title_matches, comment_matches,
902 album_matches, year_maches, year.
904 --------------------------------------------
905 0.3.5 (2009-09-21) "symplectic separability"
906 --------------------------------------------
908 Full client support for \*BSD Unixes, complete re-write of the ogg
909 vorbis audio format handler, various improvements all over the place
910 and the usual mix of bugfixes. This release marks the end of the 0.3
911 series if no serious problems show up.
913 - the new oss writer (supported on \*BSD and Linux)
914 - rewrite of the ogg vorbis audio format handler. It's
915 recommended to replace the chunk tables of existing ogg
916 vorbis files in the afs database by re-adding these files
918 - support for netmask subsets (Gerrit Renker)
919 - the new prebuffer filter
920 - improved signal handling
921 - variable fec output buffer size
922 - improved FEC timing fixes audible buffer underruns in UDP mode
923 - --log_color actually works
924 - new ls option: -d (print dates as seconds after the epoch)
925 - update to gengetopt 2.22.2
926 - support for RSA keys of size > 512 bits
927 - new option "mixer_channel" for para_fade
929 -----------------------------------------
930 0.3.4 (2009-05-07) "elliptic inheritance"
931 -----------------------------------------
933 The new udp sender, forward error correction, colored logs and various
934 other improvements. As the udp sender does not depend on any special
935 libraries, it is built unconditionally.
937 - The udp sender replaces the ortp sender. The new code uses forward
938 error correction to protect against packet losses. Many thanks to
939 Gerrit Renker for providing ipv6 support.
940 - The default port for udp streaming now defaults to 8000, like
941 for the http and the dccp senders/receivers.
942 - Loglevels are now specified as symbolic names, e.g.
944 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
945 - para_server/para_audiod: Color support for log messages.
946 - new options for mp3dec: --ignore-crc, --bufsize
947 - new audiod option: --config-file.
948 - gengetopt cleanups.
949 - Improved help/man pages: The documentation of para_audiod,
950 para_recv, para_filter and para_write now also contains
951 all options of the available receivers/filters/writers. The
952 man page of para_fade contains a description of the different
954 - More source code documentation.
957 --------------------------------------------
958 0.3.3 (2008-12-01) "axiomatic perspectivity"
959 --------------------------------------------
961 Internal code cleanups, bug fixes, improved tag handling and the new
962 amplification filter.
964 - para_server uses the generic scheduling code.
965 - overhaul of the virtual streaming system.
966 - mp3: id3 version 2 support via libid3tag (optional)
967 - ogg: vorbis comment support.
968 - aac meta info support.
969 - mp3 audio format handler cleanups.
970 - new filter: "amp" to amplify the amplitude of the audio stream
971 - new status item/database entry: amplification. It is
972 used by the amp filter to pre-amplify the audio stream.
973 - fix a close-without-open bug in para_write.
974 - fix a bug in com_init() which was introduced in 0.3.2.
975 - better error diagnostics for para_client.
977 -----------------------------------------
978 0.3.2 (2008-04-11) "probabilistic parity"
979 -----------------------------------------
981 The new para_afh executable, scheduling and documentation improvements.
983 - new ls option: -lc (list chunk table)
984 - new executable: para_afh, the stand-alone audio file handler tool
985 - afs commands can send output more than SHMMAX (32MB on Linux). This
986 also reduces the memory usage of commands that produce large amounts
988 - major scheduler and audiod cleanups.
989 - more detailed and much nicer man pages.
991 ---------------------------------------
992 0.3.1 (2008-02-23) "liquid interaction"
993 ---------------------------------------
995 A mix of cleanups, bug fixes, improvements, and some new features. No
996 significant changes to the new database (osl) code, which is generally
999 - Share some similar/duplicate code between the http and the
1001 - Generic access control lists for paraslash senders.
1002 - dccp sender: Access control lists, connection limiting and support
1003 for the allow,deny,on,off,help sender commands.
1004 - The default dccp port changed from 5001 to 8000 (suggested by
1006 - para_server starts even if not all public keys could be loaded.
1007 - Audiod performance improvements.
1008 - fix a bug in the "off" command of the http sender.
1009 - fix some fd and memory leaks.
1010 - Update to gengetopt-2.22.
1012 -------------------------------------
1013 0.3.0 (2008-01-12) "solar saturation"
1014 -------------------------------------
1016 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
1019 Usually one might expect lots of new features AND a big increase in size
1020 for a major release like this.
1022 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
1023 ever. The decrease in size is mostly due to the removal of some
1024 graphical tools (which were only quick hacks anyway). But also the
1025 fact that the mysql code is gone cuts down the size a bit.
1027 Being independent of mysql comes at a cost: The fact that paraslash
1028 now contains its own database (the object storage layer, osl) increases
1029 the (stripped) binary size of para_server by ~50K on i386.
1031 - no more restrictions on unique basenames.
1032 - independent of mysql: The new self-contained object
1033 storage layer (osl) replaces the mysql database.
1034 - New executable para_fsck: Check integrity of osl tables.
1036 - Reliable audio file move/rename detection.
1037 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
1038 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
1040 - the new osl-based audio file selector (afs) replaces the random,
1041 the playlist and the mysql selector of paraslash-0.2.x.
1042 - IPv6 support (thanks to Gerrit Renker).
1043 - paraslash-0.2.x streams are now called "moods". Writing
1044 0.3.x-mood definitions should be both easier and more
1045 powerful than writing 0.2.x-stream definitions.
1046 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
1047 been removed. The world is a better place without them. However,
1048 para_gui is still there.
1049 - afs tracks audio file selection also in playlist mode.
1050 - few easy-to-use afs commands replace the many not-so-easy-to-use
1051 mysql commands (and are available also in playlist mode).
1052 - Improved error subsystem.
1053 - The earth-shaking new logo.
1055 -----------------------------------------
1056 0.2.17 (2007-11-20) "isotropic threshold"
1057 -----------------------------------------
1059 Mainly bugfixes and cleanups in this version which marks the end of
1060 the 0.2.x series if no serious bugs show up after the release.
1062 - mysql_selector: fix a locking bug.
1063 - universal chunk queueing.
1064 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
1066 - be more carful wrt. signed vs. unsigned argument passing.
1067 - cleanup error.h and fix some references to invalid error
1069 - update to gengetopt-2.21.
1070 - update to ortp-0.13.1.
1071 - autoconf: extend checks for headers, library functions and
1072 compiler characteristics.
1073 - Fix streaming of large mp3 files.
1074 - Fix an off-by-one bug in playlist handling.
1076 --------------------------------------
1077 0.2.16 (2007-04-05) "neural discharge"
1078 --------------------------------------
1080 The main change in this release is the major audio format handler
1081 cleanup which removes some similar/duplicate code and makes it easier
1082 to implement plugins for other audio formats. Of course, the usual mix
1083 of other improvements/changes/bugfixes also made it into the release.
1085 - simplified audio format handlers (most of the handling functions
1086 were moved one layer up to the virtual streaming system).
1087 - para_server uses mmap to read audio files
1088 - repositioning of mp3 streams is much faster, in particular for
1089 jumping near the end of large mp3 files.
1090 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
1092 - fix a bug in para_filter that caused decoding of aac files
1093 to start only after a few seconds.
1094 - fix osx_writer hangs
1095 - simplified dccp code (thanks to Gerrit Renker)
1096 - the compress filter works also on big endian systems (ppc)
1098 -----------------------------------------
1099 0.2.15 (2007-02-16) "inductive resonance"
1100 -----------------------------------------
1102 Minor improvements, more documentation and a bunch of bug fixes.
1104 - para_server: The server.users file is only read once on server
1105 startup rather than for each connection
1106 - mp3dec: Fix decoding of corrupt mp3 files
1107 - afs (audio file sender) is now called vss (virtual streaming
1108 system). Consequently, the permission flags specified in
1109 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
1110 become VSS_READ and VSS_WRITE respectively.
1111 - para_audiod/para_filter: Fix a bug that caused the last chunk
1112 of audio data not being written under certain circumstances
1113 - audiod: compute the difference of server time and local time
1115 - para_server/para_audiod: Fix some memory leaks
1116 - documentation improvements
1117 - configure.ac: fix checks for para_krell
1120 -------------------------------------------
1121 0.2.14 (2006-10-15) "transient singularity"
1122 -------------------------------------------
1124 The only major enhancement of this version is the osx writer which completes
1125 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
1126 until now for reasons beyond the scope of this changelog entry.
1128 - new output plugin for Mac Os: the osx writer
1129 - rename configure command line options from --enable-xxx-headers to
1130 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
1131 - configure: new command line options: --with-mad-headers,
1132 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
1133 - some robustness fixes
1134 - dymamic audio format recognition for audiod
1135 - para_server: new command line option: --autoplay_delay
1136 - para_audiod: new command line option: --clock_diff_count
1138 ---------------------------------------
1139 0.2.13 (2006-07-14) "sonic convolution"
1140 ---------------------------------------
1142 A bunch of new features and core changes.
1144 - the new paraslash scheduler, short and sweet.
1145 - Support for m4a/mp4 files via the new aac audio format
1146 handler/filter (requires libfaad).
1147 - each writer has its own command line parser, just like
1148 para_recv and para_filter.
1149 - para_client and para_audioc use the error subsystem
1150 - writers are integrated in para_audiod (currently linux-only)
1151 - para_client is integrated in para_audiod
1152 - random/playlist selector: improved info strings
1153 - new audiod commands: tasks, kill
1154 - update to libortp-0.10.1
1155 - para_fade: wake time defaults to 8 hours from now
1156 - update to autoconf-2.60
1158 ------------------------------------------
1159 0.2.12 (2006-05-12) "oriented abstraction"
1160 ------------------------------------------
1162 Many user-visible changes in this release and lots of new
1165 - the new optional dccp sender/receiver. It uses the datagram
1166 congestion control protocol. You'll need a fairly new kernel
1168 - paraslash works on Mac OS X (thanks to Gerd Becker)
1169 - para_play renamed to para_write
1170 - modular output plugin design (writers) for para_write
1171 - new file_writer output plugin for para_write
1172 - compress filter speed improvements
1173 - update to libortp-0.9.1
1174 - update to gengetopt-2.17rc
1175 - para_client no longer depends on libreadline (as the
1176 code for the interactive mode was removed).
1177 - gcc-2-95 is no longer a supported compiler. It may still
1178 work, but it gets no more testing.
1179 - the tarball no longer contains the screenshot images which
1180 reduces its size quite a bit.
1181 - configure: new command line options: --enable-mysql-headers
1182 and --enable-mysql-libs
1184 ------------------------------------
1185 0.2.11 (2006-03-11) "atomic duality"
1186 ------------------------------------
1188 Here it is, the first paraslash release developed with git. There
1189 are fairly many user-visible changes in this release. As two out of
1190 the three "database tools" of paraslash don't use a database at all,
1191 they are now called "audio file selectors" instead.
1193 - the cdt command (change database tool) becomes chs (change
1195 - no more colon separators: The syntax of some options of
1196 para_audiod and para_filter have changed. Use --help for
1197 more info (and some examples).
1198 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
1199 - switch from cvs to git (should've done that earlier)
1200 - the new ipc subsystem
1201 - new audio file selector: playlist
1202 - para_server: the dopey selector is now called "random",
1203 and is the default selector. Use the --selector option to
1204 choose another selector at startup, or the chs command to
1205 change the selector at runtime.
1206 - X86_64 fixes (thanks to Steffen Klassert)
1209 --------------------------------------
1210 0.2.10 (2006-02-17) "cyclic attractor"
1211 --------------------------------------
1213 Huge documentation update, a scrollable window for para_gui, ortp
1214 improvements, and of course many small fixes not mentioned here.
1215 The diffstat below is rather misleading as most insertions are due
1216 to the new source documentation.
1219 - para_server also uses the new error subsystem
1220 - lots of new documentation (UTSL)
1222 - keysyms for cursor keys and for next/previous page keys
1223 - scrollable output window
1224 - new internal commands: scroll up/down, page up/down
1225 - fix color of command output.
1226 - ortp: the --chunk_time and --header flags are no longer needed
1227 for para_recv/para_audiod as this information is now encoded in
1228 each rtp packet sent by para_server.
1230 -------------------------------------------
1231 0.2.9 (2006-01-24) "progressive turbulence"
1232 -------------------------------------------
1234 Internal audiod receivers/filters, the new error subsystem and
1235 a lot of small improvements.
1237 - para_recv and para_filter are integrated into the para_audiod
1238 binary, i.e. audiod no longer spawns a new process for
1239 each receiver/filter. As para_recv and para_filter might be
1240 useful as standalone programs, they still get built (linked
1241 against the same object files that are also used for audiod).
1242 - further ortp timing improvements should reduce the CPU usage
1243 of the ortp receiver.
1244 - improved audio grabbing. The 'grab' command of para_audiod
1245 has its own set of command line options. Read the output of
1246 "para_audioc help grab" for more info.
1247 - oggdec: configurable input prebuffer size.
1248 - the new error subsystem gives better error diagnostics
1249 and reduces code size.
1251 -----------------------------------------
1252 0.2.8 (2006-01-02) "dynamic accumulation"
1253 -----------------------------------------
1255 The new modular filter design and the para_play-hangs bugfix.
1257 - new executable: para_filter. It combines para_mp3dec,
1258 para_oggdec and para_compress. It also adds a further filter
1259 type, wav, that just inserts a wave header at the desired point
1260 of the filter chain. All 'piping' is done in-memory (i.e. no
1261 read/write operations are used).
1262 - para_play: fix a stupid bug that caused it to hang under
1263 certain circumstances.
1265 -------------------------------------------
1266 0.2.7 (2006-12-27) "transparent invariance"
1267 -------------------------------------------
1269 Not many user-visible changes but a fair amount of internal improvements.
1271 - The http sender buffers data if it can not be sent
1272 out immediately (because the socket is not writable). This
1273 should prevent para_server from shutting down the connection
1274 too early on a loaded network.
1275 - para_play also prebuffers data if it is told to start at a
1276 future time by the --start_time option.
1277 - The return of para_recv: It combines para_ortp_recv and
1278 para_http_recv. Use the --receiver option to switch between
1279 the two. para_recv builds without libortp, but contains
1280 only the http receiver in this case.
1281 - update to ortp 0.8.1. As this ortp release contains incompatible
1282 changes, para_recv-0.2.7 won't link against older ortp libs.
1283 - improved ortp timings.
1284 - use of gcc-extensions that #define away for non-gcc and
1287 -------------------------------------------
1288 0.2.6 (2005-10-29) "recursive compensation"
1289 -------------------------------------------
1291 Transparent session encryption (uses openssl's Alleged RC4 cipher),
1292 the internal find command and several other improvements and cleanups.
1294 - Encrypt the session if encryption is requested by the client
1295 (default for para_client 0.2.6). This is backwards
1296 compatible, so older clients can still connect to para_server
1297 0.2.6. Use the new client option --plain to request an
1298 uncrypted session (off by default, must be set to on in
1299 order to connect to para_server 0.2.x with 0 <= x <= 5).
1300 - para_server uses an internal function to locate audio files
1301 rather than calling find(1). The server option
1302 --mysql_audio_file_dir replaces --mysql_find_cmd.
1303 - documentation update
1305 - header file cleanup
1306 - para_client code cleanup
1307 - para_gui: faster display of output of display commands
1309 ------------------------------------------
1310 0.2.5 (2005-10-13) "aggressive resolution"
1311 ------------------------------------------
1313 This release adds internal senders, i.e. no more external programs are
1314 spawned for sending out the audio data. There are two different senders
1315 available: The http sender and the ortp sender (former para_send which
1316 is no longer needed).
1318 The new sender code has a plugin-like design so it can be easily
1319 extended should there be be any future need for supporting another
1320 network streaming protocol. All senders are completely independent of
1321 each other. In particular, the http and the ortp sender can operate
1324 - new server command: sender to control senders at runtime.
1325 Read the output of "para_server -h" and "para_client help
1326 sender" for more information.
1327 - para_recv renamed to para_ortp_recv
1328 - new executable: para_http_recv, a simple command line
1330 - major afs/mp3/ogg code simplifications due to internal
1332 - ogg timing improvements
1333 - fix several minor memory leaks (found by valgrind)
1334 - empty stream definitions work again
1335 - com_ne(): ignore errors on remove
1336 - audiod: fix segfault on server restart
1338 ---------------------------------------
1339 0.2.4 (2005-09-21) "toxic anticipation"
1340 ---------------------------------------
1342 Several small improvements, fixes and the new grab command.
1345 - new command: "grab" to grab the output of the stream reader
1346 or any filters. Read the output of "para_audioc help grab"
1347 for more information.
1350 - audioc: new command line option: --bufsize to specify a
1351 buffer size different from the default size 8192.
1352 - improved error diagnostics for para_play.
1353 - new configure option: --enable-ssldir so search for openssl in
1355 - sdl_gui: Make it look nice again for 1024x768
1356 - server: report total size of memory allocated with sbrk by malloc,
1357 new command line option: --announce_time
1359 -----------------------------------------
1360 0.2.3 (2005-09-01) "hydrophilic movement"
1361 -----------------------------------------
1363 Two new executables and major feature enhancements.
1365 - audiod filters: It is now possible to specify arbitrary many
1366 (including none) filters for each supported audio
1367 format. This can be used e.g. for normalizing volume,
1368 transforming or grabbing the audio stream, or for using
1369 visualizers. Read the output of "para_audiod -h" for the
1370 syntax of the new --filter_cmd option.
1371 - new executable: para_play, a tiny alsa player. It
1372 can play wave files or raw pcm (16 bit little endian)
1374 - new executable: para_compress, a dynamic range compressor
1375 intended to keep audio output at a consistent volume. Derived
1376 from [AudioCompress](http://trikuare.cx/code/AudioCompress.html).
1377 - audiod: New option: --stream_delay. This can be used in
1378 a local network to syncronize the audio output of all
1379 clients that play the same stream.
1381 ------------------------------------------
1382 0.2.2 (2005-08-19) "tangential excitation"
1383 ------------------------------------------
1385 Mostly internal changes in this release, but also some new commands
1386 for the mysql database tool.
1388 - cleanup exec.c, fix para_exec bug
1389 - compile time loglevel (log messages below the given level
1390 won't be compiled in, which reduces the size of the
1392 - new log macros that shorten the size of the source code.
1393 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
1394 to send only zeros. With this workaround, para_audioc works
1396 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
1397 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
1398 (new entry), "snp" (set numplayed). Read the manual for more
1401 ---------------------------------------
1402 0.2.1 (2005-08-15) "surreal experience"
1403 ---------------------------------------
1405 Here comes paraslash-0.2.1. It contains a couple of new features and,
1406 surprise, only minor bug fixes.
1408 - kill noisy mp3 debug message
1409 - cleanup of the build system
1410 - para_server and para_client directly use the crypto routines
1411 of the openssl library rather than invoking the openssl command
1413 - server/audiod: new option --user to switch to the given user
1414 when invoked as root. Read the output of "para_server -h" for
1416 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
1417 status. Default: "para_audioc stat"
1418 - sdl_gui: new option --pic_cmd to be used to download the picture.
1419 Default: "para_client pic"
1420 - audiod: 5 slots ought to be enough for everybody
1421 - audiod: new status item: Uptime, kill hup command
1423 ------------------------------------------
1424 0.2.0 (2005-08-06) "distributed diffusion"
1425 ------------------------------------------
1427 After several month of increased development activity, paraslash-0.2.0
1428 has arrived. It contains many new features and is much more
1429 self-contained than the old 0.1.x series. Enjoy!
1431 - para_server: fix hang on song change and crash on sighup.
1432 Speed up mysql queries. The DIR_LIKE macro is gone.
1433 - new executables: para_audiod, the local audio daemon that
1434 starts playback (uses SCM_CREDENTIALS socket magic) and
1435 para_audioc, the corresponding client.
1436 - new executables: para_mp3dec/para_oggdec, two really teensy
1437 decoders. para_mp3dec is based on libmad, para_oggdec requires
1439 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
1440 they are now called para_send and para_recv respectively.
1441 - documentation updates
1442 - para_gui is themable. For now there is the default theme that
1443 looks as before and the simple theme: blue and easy.
1444 - gui: audio streaming is now handled by audiod. Time display shows
1445 playback time rather than streaming time
1446 - slider: update to libzmw-0.2.0
1447 - para_krell: fix crash on server shutdown
1448 - switch from gzip to bzip2
1450 ----------------------------------------
1451 0.1.7 (2005-04-18) "melting penetration"
1452 ----------------------------------------
1454 The main change in this release is clearly the oggvorbis rewrite,
1455 but there are also lots of smaller changes. If you intend to use both
1456 the mp3 and the ogg plugin, it is recommended to use software mixing,
1457 e.g. the dmix plugin which is provided by ALSA.
1459 - new executables: para_ovsend and para_ovrecv for sending/receiving
1460 oggvorbis files via rtp. Requires the open rtp library. Get it at
1461 http://www.linphone.org/ortp/
1462 - rewrite of the ogg_vorbis core code
1463 - configure detects libzmw and, if detected, includes
1464 para_slider to the list of binaries to be built by make
1465 - server stream writers read from their associated fifo rather
1467 - slider: two new sliders, lastplayed and numplayed
1468 - fix nasty double free bug which caused random segfaults in case of
1469 mp3 files with invalid header information
1470 - gui: new command line option: --stream_timeout=seconds to
1471 deactivate a slot if it is idle for that many seconds (default=`5')
1474 ---------------------------------------
1475 0.1.6 (2005-03-05) "asymptotic balance"
1476 ---------------------------------------
1478 Only little user-visible changes in this release. Mainly bugfixes and
1479 core code cleanup. This is probably the most stable version ever if you
1482 - fix several memory leaks
1483 - rename default name of mysql database from "music" to "paraslash".
1484 Use para_server's --mysql_database option if you do not want to
1485 rename your old database.
1486 - rework ogg vorbis code
1487 - make update command work on mysql servers with LOCAL_INFILE
1489 - gui: improved stream I/O (slots)
1490 - simplified audio format API
1491 - para_pob_ogg is gone
1493 ------------------------------------
1494 0.1.5 (2004-12-31) "opaque eternity"
1495 ------------------------------------
1497 Let's slide gently into the new year.
1499 - new: para_slider (not built automatically, type "make
1500 para_slider" to build). A toy for those who always felt that
1501 creating stream definitions is difficult. See screenshots,
1502 README and FEATURES for more info.
1503 - improved signal handling. Fixes server segfault on SIGHUP
1504 for linux kernels newer than Aug 24 2004 and makes para_gui
1506 - reload database tool on SIGHUP
1507 - improved help message for sl
1508 - do not log "broken pipe" messages as errors. They are
1510 - fix wrong error message on permission errors
1512 -----------------------------------------
1513 0.1.4 (2004-12-19) "tunneling transition"
1514 -----------------------------------------
1516 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1517 Hopefully, most of them got wiped out with this release. Some
1518 enhancements went also in.
1520 - improved error diagnostics for all commands
1521 - stradd/picadd: overwrite previous contents if entry already
1522 exists, rather than returning errors
1523 - stradd: use current stream if invoked without args
1524 - faster (and hopefully more stable) ogg-vorbis handling
1525 - para_krell: reap children to avoid zombie-flooding in case
1526 no server is running
1527 - si: report also server pid
1528 - server: don't busy-loop if dbtool reports only invalid files.
1529 - gui: CTRL+C works again, fix stream_read command line option
1531 - fix mysql dbtool startup in case no database exists
1532 - many small fixes and cleanups
1534 ---------------------------------------
1535 0.1.3: (2004-12-10) "vanishing inertia"
1536 ---------------------------------------
1538 Starting from this release, the database tools are integrated in the
1539 server binary. This decreases server startup time, reduces code size
1540 and speeds up database commands. However, the layout of the underlying
1541 mysql database changed only slightly and 0.1.3 should be backwards
1542 compatible in that respect.
1546 - If mysql is not detected at compile time, or fails to init
1547 at runtime, fall back to the dopey database tool which should
1549 - para_dbtool and dbtool.conf are gone. All mysql specific
1550 options are read from server.conf and are prefixed by 'mysql_'.
1551 - new command: cdt (change database tool)
1552 - new command line option: dbtool (choose startup database tool)
1553 - The name of current stream is now stored in the database,
1554 so paraslash remembers its current stream when restarted.
1555 - new command: csp (change stream and play)
1556 - para_gui also reports current database tool and server uptime
1558 -------------------------------------------
1559 0.1.2: (2004-11-28) "spherical fluctuation"
1560 -------------------------------------------
1562 Point release before the big dbtool changes go in.
1564 - dbtool: rename ca to cam (copy all meta data). It now also
1565 copies numplayed and lastplayed time as well as the picture
1567 - fix endless-loop-bug caused by mp3 files with invalid header
1569 -----------------------------------------
1570 0.1.1: (2004-11-05) "floating atmosphere"
1571 -----------------------------------------
1574 - new dbtool command: mbox. Browse your sound-file collection
1575 with your favorite mail reader.
1576 - several small fixes
1578 -------------------------------------
1579 0.1.0: (2004-10-22) "rotating cortex"
1580 -------------------------------------
1582 - fix logging bug for loglevel > VERBOSE
1584 - correct timings for vbr mp3s
1585 - modular audio format support
1586 - ogg-vorbis support (experimental)
1587 - new server option: autoplay
1589 -----------------------------------------
1590 0.0.99: (2004-07-25) "harmonic deviation"
1591 -----------------------------------------
1593 - rename projectname from icc to paraslash (play, archive, rate
1594 and stream large audio sets happily)
1595 - paraslash is no longer restricted to one particular audio
1597 - new dbtool commands (stradd, strq, strdel) for easy stream
1598 managment w/o configuration file. That obsoletes stream_defs
1599 file/config option for dbtool.
1600 - picadd accepts jpeg data from stdin
1601 - new server commands: ps (select previous stream), sc (song change)
1602 - new default pictures for sdl_gui
1603 - gui: new key_map option for binding commands and internal
1604 functions to arbitrary keys, nice help screen, rip out
1605 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1606 show silly logo on startup
1607 - new executables: para_fade for fading volume, para_dbadm for
1608 manipulating attributes
1609 - cdb adds _all_ tables to mysql database
1610 - revised and beautified documentation
1611 - sample dbtool rewritten in C
1614 ---------------------------------------------
1615 0.0.98: (2003-12-26) "incremental smoothness"
1616 ---------------------------------------------
1618 - kick icecast in favour of poc. That removes some races and reduces
1619 core code considerably.
1620 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1621 give finer info on afs' status.
1622 - gui can start decoder (see config options). Further new gui
1623 commands: refresh (^L), jmp (F1-F10)
1624 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1625 terminates gui. This fixes dead instances consuming memory
1627 - new dbtool command: verb for sending verbatim sql queries.
1628 - fix pid_list races (by removing pid_list)
1631 --------------------
1632 0.0.97: (2003-10-26)
1633 --------------------
1635 - installation prefix now defaults to /usr/local
1636 - new commands for gui: snozze, sleep and reread config
1637 - config file for gui and sdl_gui
1638 - fix problems with filenames containing funny characters
1639 (reported by Thomas Forell)
1640 - improved signal handling for gui, now it rereads conf on SIGHUP
1641 - new dbtool command: cdb (create database)
1642 - switch from argtable to gengetopt
1643 - major code cleanup and speed improvements
1644 - fix several potential buffer overflows
1645 - many small fixes and cleanups
1651 - easy stream_defs syntax
1652 - sdl_gui can display images associated to the file being played
1653 - Major feature enhancements for icc_gui including dynamic text
1654 placement and the top/bottom window design
1655 - vrfy/clean now also checks for NULL values in attributes as
1656 well as for invalid picture pointers
1657 - fix long outstanding case sensitivity bug
1658 - many small fixes and cleanups
1664 - sdl gui runs much faster
1665 - new dbtool command: ca (copy attributes)
1666 - count and display number of times the song has been played
1667 - new feature: scoring
1668 - command line options for sdl_gui
1669 - simpler syntax of streams file
1670 - decrease network traffic of stat
1672 - many small fixes and cleanups
1678 - new server command: ns (next stream)
1679 - new icc_gui command: c (change stream)
1681 - stat shows also id3 tag info
1683 - log flodding bug fixed
1684 - many small fixes and cleanups
1690 - colors for icc_gui
1691 - icc_gui sets volume directly (linux only)
1692 - proper locking that fixes some races
