5 0.7.3 (to be announced) "weighted correctness"
6 ----------------------------------------------
8 - Old style PEM keys are now deprecated. They still work but their
9 use results in a run-time warning. The removal of PEM key support is
10 scheduled for paraslash-0.8.0.
11 - Version 1.0 of the openssl library has been deprecated. A warning
12 is printed at compile-time on systems which have this outdated version
13 because it will no longer be supported once paraslash-0.8.0 comes out.
14 - A spring cleanup for the senescent code in fd.c.
15 - The --admissible option of the ls command now takes an optional
16 argument. When invoked like --admissible=m/foo, only files which are
17 admissible with respect to mood foo are listed.
18 - The select server command is now quiet by default, The new --verbose
19 option can be used to show information about the newly loaded mood

26 0.7.2 (2023-03-08) "optical friction"
27 -------------------------------------
29 The improved error reporting of afs commands and the two new options
30 for the sleep subcommand of para_mixer are the most prominent features
31 of this minor release. The bulk of the changes are cleanups of the
32 afs and net subsystems, which should both have no user-visible impact.
34 - A major cleanup of the audio file selector.
35 - The client no longer prints error messages from afs commands to
37 - The sleep subcommand of para_mixer gained two options to control
38 the startup mood and the time period before fade-out starts. A bunch
39 of further improvements for this subcommand went in as well.
40 - Minor cleanup of the net subsystem.
41 - The openssl specific code now employs the EVP API to compute hashes.
42 It should compile without warnings against openssl-3.
43 - The deprecated syntax for specifying negative offsets in the argument
44 to the "ff" server command has been removed.

51 0.7.1 (2022-10-03) "digital spindrift"
52 --------------------------------------
54 The two new ll commands and the internal mp4ff library are the most
55 user-visible changes of this release. On top of that there are two
56 core changes which aim to improve the robustness of the code but which
57 are otherwise invisible: the switch from select(2) to poll(2) and the
58 revised memory allocation API which checks for integer overflows. The
59 release also comes with a slight change to the build system and the
60 usual mix of bug fixes and minor improvements not mentioned here.
62 - The autogen.sh script now only creates the autoconf specific files
63 but no longer runs configure, make and the test suite.
64 - A stripped down copy of the discontinued libmp4ff library has become
65 part of the paraslash code base. As a result it is no longer necessary
66 to install faad from source to get support for aac/m4a files. The
67 faad decoder package must still be installed.
68 - The log level of the running daemon can now be changed with the
69 new ll command. It is available for para_server and para_audiod.
70 - All calls to select(2) have been replaced by calls to poll(2)
71 to avoid known shortcomings of the select API.
72 - All allocation functions now check for integer overflow. Since this
73 requires support from the compiler, the oldest supported gcc version
74 has been bumped to gcc-5.4 (released in 2015).

81 0.7.0 (2022-03-12) "seismic orbit"
82 ----------------------------------
84 The major incompatible change which requires to bump the major version
85 is the switch from sha1 to sha256, see below for details. However,
86 there are many other improvements, the usual amount of bug fixes and
87 a couple of new features.
89 - Starting with paraslash-0.7.0, the sha256 hash value of each known
90 audio file is stored in the database while older versions employed the
91 sha1 hash algorithm which has been considered insecure since 2005
92 and should no longer be used today. The switch from sha1 to sha256
93 requires users to upgrade their database using the new para_upgrade_db
94 program, followed by re-adding all files to recompute the hashes. With
95 this approach all metadata stored in the database (last played date,
96 num played value, moods, playlists, attributes etc.) are kept. An
97 simpler alternative is to start over from scratch by running the
98 "init" command but this will lose these metadata.
99 - Server and client now hash the session keys with sha256 rather
100 than sha1 during the initial handshake. This feature is optional and
101 backwards compatible: old clients can still connect to a new server
102 (using sha1). Also new clients can connect to an old server (again
104 - The new "duration" keyword of the mood grammar makes it possible to
105 impose a constraint on the duration of the admissible files.
106 - The long deprecated version 1 mood syntax is no longer supported.
107 - Paraslash writers handle early end-of-file more gracefully.
108 - The alsa writer no longer warns about spurious underruns.
109 - The score formula of the audio file selector has been reworked.
110 - Cleanups of the doubly linked lists code.
111 - New option for configure: --enable-ubsan to detect and report undefined
113 - The "tasks" server command has been removed.
114 - The fancy new logo and a minor overhaul of the web pages.

126 still be supported for some time and subsequent maintenance releases
129 - The udp sender no longer crashes when empty chunks are encountered.
130 - Fix a double-free bug in the exit path of the server.

149 of life and will no longer be supported. All users should upgrade to
150 a more recent version at this point.
152 - Fix an issue with the bash completion script.

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

200 0.6.2 (2018-06-30) "elastic diversity"
201 --------------------------------------
203 The main new feature of this release is the --listen-address option
204 for para_server and para_audiod. But there are also a large number of
205 small improvements and bug fixes all over the place. The user-visible
208 - para_gui no longer waits up to one second to update the screen when
209 the geometry of the terminal changes.
210 - Minor documentation improvements.
211 - Improvements to the crypto subsystem.
212 - The server subcommand "task" has been deprecated. It still works,
213 but prints nothing. It will be removed in the next major release.
214 - Server log output is now serialized, avoiding issues with partial
216 - It is now possible to switch to a different afs database by changing
217 the server configuration and sending SIGHUP to the server process.
218 - New server options: --listen--address, --http-listen-address and
219 --dccp-listen-address. These options restrict the set of listening
220 addresses of the TCP and DCCP sockets of the server process.
221 - The help commands of server, audiod, play now support --long. By default,
222 the short help is shown.
223 - The code which merges the command line options with the config file
224 options has been consolidated.
225 - If the current audio file is renamed, the status items are now updated
227 - After the server process received SIGHUP, changes to the current audio
228 file did not trigger an update of the status items. This has been fixed.

238 The highlight of this release is the version 2 mood parser. But there
239 is a lot more than that, as summarized in the list below. And of
240 course we have many small usability improvements and bug fixes not
243 - A more intuitive syntax for moods ("version 2 moods"). The
244 traditional version 1 moods are still supported but are deprecated
245 now. Removal of the version 1 mood parser is scheduled for the next
247 - Flex and bison are now required to build para_server.
248 - New sort order for the ls command: -s=h sorts the ls output by hash
249 value of the audio file.
250 - autogen.sh now runs the test suite after a successful build.
251 - The contents of overview.pdf have been integrated into the user
253 - Fixed sized audio format headers for ogg/opus streams.
254 - The doxygen source browser has been disabled temporarily. The
255 API reference is still online, though.
256 - Overhaul of the source code documentation.
257 - The deprecated --full-path option of the ls command has been
258 removed. It was a no-op since 0.6.0.
259 - The wma decoder has been cleaned up and its bitstream API made
261 - The image/lyrics ID status items of the current audio file are now

290 A couple of fixes for serious old bugs have accummulated in the maint
291 branch since paraslash-0.5.7 was released nine months ago. So here
292 is another 0.5.x release. As usual, all commits in the maint branch

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

388 - The wma decoder and audio format handler now correctly decodes
389 files with unusual block sizes.
390 - We now compile with -Wformat-signedness if possible.

403 Many fixes for nasty bugs have accumulated over the years since 0.4.13
404 was released in 2013. This release contains all of them. It is the
405 last v0.4.x release, so v0.4.x is now end of life. The maint branch
406 of the git repository has been forwarded to v0.5.7 and will start to
407 receive important fixes for 0.5.x, which is now in maintenance mode.
409 - Fix for the "double encryption bug" with gcrypt, which caused
410 garbage to be sent to stat clients.
411 - The "prev" command of para_play now works as expected.
412 - Invalid parameters for the begin and end chunk no longer cause
413 the afh receiver of para_recv to segfault.
414 - A fix for an assertion that triggered in the FEC slice setup code.
415 - Closing the terminal with a running para_gui causes the process to
416 die, rather than using 100% of CPU time.
417 - para_gui no longer shows stale information about the previous
419 - A fix for a bug in the fec decoder which caused aborts if the buffer
421 - The assertion in the buffer tree code no longer triggers.

423 error no longer occurs on attribute changes.
424 - A NULL pointer dereference in com_sender() has been fixed.
425 - The -i option of lsatt works as advertised.

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

466 - On Linux systems, local sockets are now created in the
467 abstract name space by default. This allows to get rid of
468 the socket specials in /var/paraslash.
469 - The --user-allow option of para_audiod now accepts also
470 usernames rather than only user IDs.
471 - New autoconf macros to avoid duplication in configure.ac.
472 - Status items (as shown by para_gui) are updated correctly
473 when the meta information of the current audio changes.
474 - para_server and para_audiod no longer refuse to start in
475 the background if no log file is given. Instead, all log
476 messages go to /dev/null in this case.
478 - New syntax for the -l and -s options of the ls command.
479 These options should now be specified as -l=v rather than
480 -lv, for example. The old syntax still works, but support
481 will be dropped in v0.6.0.

534 The new sync filter, the AES_CTR128 stream cipher and the overhauled
535 network code are the highlights of this release. It also includes a
536 fair number of smaller fixes and improvements not mentioned here.
538 - The new sync filter synchronizes playback between multiple
540 - Connections between para_server and para_client are now
541 encrypted by means of AES rather than RC4 if both sides
542 support it. RC4 is still available as a fallback. This
543 feature is fully transparent, i.e. no command line options
544 are necessary, and a client linked against openssl can
545 speak with a server linked against libgcrypt and vice versa.
546 - Major cleanup of the networking subsystem.
547 - Improvements to para_fade: the new set mode, multi-channel
548 initial volumes, better error logging.
549 - The man pages of para_audiod, para_filter, para_recv, and
550 para_write contain the relevant options for receivers, filters,
551 writers. This broke in 0.5.0.
552 - ogg/vorbis latency improvements.
553 - Improved user manual.
554 - Minor fixes to avoid clang warnings.

560 ------------------------------------------
561 0.5.1 (2013-12-20) "temporary implication"
562 ------------------------------------------
564 Lots of fixes and improvements all over the place, and a major overhaul
567 - Audiod improvements and fixes.
568 - Buffer tree robustness improvements.
569 - Cleanup of the mood subsystem.
570 - Fixes and cleanups for the flac decoder.
571 - Latency improvements for the ogg/opus decoder.
572 - Crypto support is now optional. On systems without
573 openssl/gcrypt, the build succeeds but para_server,
574 para_audiod, para_client won't be built.
575 - The build system now works for cross-compile setups.
576 - The dependency tree has been flattened, which speeds up
577 builds and avoids to recreate the man pages on every change.
578 - The error code helper has been rewritten from perl to C,
579 which further improves build time.
580 - Many small bugs in the build system have been identified

587 ----------------------------------------
588 0.5.0 (2013-08-23) "invertible validity"
589 ----------------------------------------
591 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
593 - The sideband compatibility code has been removed, hence
594 sideband connections (introduced in 0.4.11) are now mandatory.
595 - Addblob commands can produce output.
596 - The stat command no longer sends garbage when para_server was
597 compiled against libgcrypt.
598 - Dependencies for gengetopt files are computed automatically.
599 This eliminates a constant source of build bugs.
600 - The setatt command now accepts file name patterns rather than only
602 - overview.pdf is now based on dia, a simple diagram creation program.
603 The new version is much more detailed and contains descriptions of
604 the various programs of the paraslash package.
605 - The separator of all multi-word options has been changed from
606 underscore to dash. For example --log_color becomes --log-color.
607 - Overhauled web pages and the new logo.

613 --------------------------------------
614 0.4.13 (2013-07-29) "spectral gravity"
615 --------------------------------------
617 One more 0.4.x release before the API-breaking changes for 0.5.0 go
618 in. The main features of this release are the ogg/opus audio format,
619 and UTF-8 support, but it includes also tons of other improvements
620 and fixes all over the place.
622 - New audio format: ogg/opus.
623 - UTF8 support for para_gui and the mp3 audio format handler.
624 - Scheduler improvements and fixes.
625 - The obsolete gettimeofday() function has been replaced
626 by clock_gettime() on systems which support it.
627 - Speed and usability improvements for para_gui.
628 - para_client now restores the fd flags of stdin and stdout
630 - Improved manual pages.
631 - Consistent version strings for all executables.
632 - Reduced dependencies on generated files result in fewer
633 recompilations on changes.
634 - Performance improvements for the compress filter.
635 - Improved downloads web page.
637 -----------------------------------------
638 0.4.12 (2012-12-20) "volatile relativity"
639 -----------------------------------------
640 The new command line player, the resample filter, ALSA support for
641 para_fade, and the improved build system are the highlights of this
642 release which probably marks the end of the 0.4.x series.
644 - The afh receiver and the para_play executable.
645 - The resample filter: A sample rate converter based on
647 - The "versions" directory has been removed from the master
648 branch. The tarballs of the old releases are now available
649 in the new "releases" branch.
650 - Overhaul of the build system: All generated files are now
651 written to the "build" directory.
652 - The modular mixer API and the alsa mixer.
653 - Minor fixes for the osx writer.
655 --------------------------------------
656 0.4.11 (2012-07-20) "mutual diversity"
657 --------------------------------------
659 The major feature in this release is the new sideband API for
660 client-server communication. This API will be used exclusively starting
661 with 0.5.0, which breaks backward compatibility but allows to get rid
662 of quite some compatibility code. Other noteworthy changes include
663 decoder latency improvements and a long-standing bug fix for the
666 - Sideband connections: If both para_server and para_client
667 support this feature, data is sent as a multiplexed stream.
668 - The --no_default_filters option of para_filter has been
670 - Several fixes and latency improvements to various decoders.
671 - The ALSA writer now limits the prebuffer time to 500ms.
672 - Documentation improvements.
673 - Overhaul of the command_util.sh script.
674 - Fixes for some minor problems found by the clang analyzer.
675 - Compiles (almost) without warnings on gcc-3.
676 - Robustness improvements of the buffer tree code.
678 ------------------------------------------
679 0.4.10 (2012-03-30) "heterogeneous vacuum"
680 ------------------------------------------
682 Nothing earth-shaking in this release, but quite a few usability
683 improvements and the usual mix of cleanups and fixes.
685 - The --no_default_filters option of para_filter has been
686 deprecated. It still works but has no effect and will be
687 removed in the next version.
688 - para_gui now prints also the stderr output of the executing
689 command in the bottom window.
690 - Cleanup and consolidation of the various wrappers for
691 write(), writev(), send() and friends.
692 - The obscure error messages on mmap() failures have been
693 replaced by meaningful messages. This affects mainly
695 - para_audioc: Cleanups and memory leak fixes.
696 - Test 0004-server no longer fails if para_server is not
698 - New configure options: --with-id3tag-{headers,libs}.
700 -------------------------------------
701 0.4.9 (2011-12-06) "hybrid causality"
702 -------------------------------------
704 Support for another audio format, interactive mode for para_client
705 and para_audiod and many small improvements/fixes all over the place.
707 - Support for flac, the free lossless audio codec.
708 - Fix for an endless loop in the mp3 decoder for certain
710 - When executed without specifying a command, para_client
711 and para_audioc start an interactive shell (requires
712 libreadline being installed). The interactive mode offers
713 full tab completion and command line history.
714 - autogen.sh now detects a distcc setup and adjusts the
715 parameter for the -j option of make accordingly.
716 - Shared memory areas are no longer restricted to 64K. We now
717 detect the maximal size of a shared memory area at runtime.
718 - cleanup of the internal uptime API.
719 - para_server prefaults the mmapped audio file to avoid
720 delays on slow media.
721 - A new test for the test-suite that exercises the
722 communication between para_server and para_audiod.
723 - The alsa writer eats up less CPU cycles when configured to
725 - Simplified and unified receiver code.
727 - Commands which print a list of matching audio files now
728 emit a meaningful error message if no audio file matched the
731 --------------------------------------
732 0.4.8 (2011-08-19) "nested assignment"
733 --------------------------------------
735 Gcrypt support, the overhauled osx writer and regex format specifiers
736 are the highlights of this release.
738 - support for libgcrypt as a drop-in replacement for openssl.
739 Run configure --enable-cryptolib=gcrypt to link against
740 libgcrypt. The two crypto implementations are compatible to
741 each other, i.e. a para_client executable linked against
742 gcrypt can connect to para_server linked against libssl
744 - Rewrite of the osx writer (output plugin for Mac OS).
745 - audiod: The format specifier for receivers, filters and
746 writers is now treated as a regular expression. This allows
747 to replace 5 lines in the config file (one for each audio
748 format) by one single line. See the manual for details.
749 - The \*.cmdline.[ch] files are no longer contained in the released
750 tarballs. This reduces the size of the tarballs but requires
751 gengetopt to build the tarball.
752 - Compiles cleanly also with llvm/clang.
753 - Corrupt mp3 files are handled more gracefully.
754 - The alsa writer uses poll fds instead of computing timeouts.
755 - Cleanup of the generic writer API.
756 - sched: Optimized zero timeouts.
757 - vss timeout cleanups.
758 - oggdec fixes and improvements.
760 --------------------------------------
761 0.4.7 (2011-06-01) "infinite rollback"
762 --------------------------------------
764 The new ao writer, support for ssh RSA keys and a couple of other
767 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
768 platforms through the libao audio library.
769 - Support for RSA keys generated with ssh-keygen.
770 - configure: improved options for ogg/vorbis/speex.
771 - The git version reported by --version always matches HEAD.
772 - The autogen script detects the number of processors and
773 runs a parallel make if possible.
774 - Major cleanup of the crypto API.
775 - Documentation updates.
777 ------------------------------------------
778 0.4.6 (2011-03-31) "deterministic entropy"
779 ------------------------------------------
781 Lots of ogg/vorbis improvements, the new test suite, enhancements
782 for para_gui and a fair amount of other bug fixes.
784 - For DCCP/OGG streams the audio file header is only sent once
785 at the beginning of the stream rather than periodically
786 every five seconds. This reduces network traffic and the
788 - The vorbis comment header is replaced by an empty dummy header
789 before the header is sent over the network. This also results in
790 less network traffic and smaller FEC groups.
791 - The new "test" make target allows to perform some sanity checks prior
792 to installing the package.
793 - ogg timing fixes and performance improvements
794 - Scheduler improvements
795 - Proper exit codes for para_write
796 - para_gui: New option --theme to select a startup theme. Several
797 other improvements and fixes.
798 - aacdec error message cleanups
799 - simplified color error handling
801 --------------------------------------------
802 0.4.5 (2010-12-17) "symmetric randomization"
803 --------------------------------------------
805 Bug fixes, internal cleanups and variable-sized FEC slices.
807 - Contains a fix for an invalid-free-bug in the ogg audio format
809 - Switching off the DCCP sender works again.
810 - para_audiod handles crashes of para_server more robustly.
811 - Internal scheduler and writer cleanups.
812 - Reduced latency due to variable-sized FEC slices.
813 - Improved documentation and error diagnostics.
814 - The build of para_server is now optional, allowing the build
815 to succeed in case libosl is not installed.
817 ------------------------------------------
818 0.4.4 (2010-08-06) "persistent regularity"
819 ------------------------------------------
821 Support for yet another audio format, para_write improvements and
824 - Support for the speex codec.
825 - Support for sample formats other than 16 bit little endian.
826 - error2.h is now created by a perl script which speeds up configure
828 - Fix a bug in the aac decoder which could lead to segfaults in
829 para_filter/para_audiod.
830 - Fixes for autoconf-2.66.
832 ----------------------------------------
833 0.4.3 (2010-07-05) "imaginary radiation"
834 ----------------------------------------
836 Many improvements for the DCCP and the UDP transport, the new user
837 manual and the usual mix of bug fixes and internal improvements.
839 - FEC support for the DCCP sender (Gerrit Renker). The new
840 --dccp_max_slice_size, --dccp_data_slices_per_group and
841 --dccp_slices_per_group options can be used to set the FEC
842 parameters for the DCCP transport.
843 - DNS lookups for UDP targets (Gerrit Renker).
844 - The new user manual replaces the README, README.afs, REQUIREMENTS
845 and INSTALL documents.
846 - Fix an end-of-file detection bug in the oggdec filter.
847 - The new nonblock API.
848 - Both options of the oggdec filter have been removed.
849 - New debug mode for the internal scheduler.
851 ------------------------------------------
852 0.4.2 (2010-04-23) "associative expansion"
853 ------------------------------------------
855 It's been some time since the last release, but finally here is
856 paraslash-0.4.2. The bulk of the changes comes from the new buffer
857 tree API, but there are changes all over the tree. Mainly performance
858 and usability improvements, but also quite some bug fixes.
860 - The new buffer tree API.
861 - DCCP: Support for CCID negotiation (Gerrit Renker).
862 - UDP robustness fixes.
863 - The --bufsize option for mp3dec is gone as it no longer makes sense
864 for the new buffer tree API.
865 - Fix audible buffer underruns for wma streams.
866 - The alsa writer no longer prints meaningless underrun durations.
867 - audiod: Defaults work also for udp streams. If no filter is
868 given for an audio format that is received via upd, fecdec is
869 automatically added as the first filter (along with the decoder).
871 ---------------------------------------
872 0.4.1 (2009-12-22) "concurrent horizon"
873 ---------------------------------------
875 Support for another audio format, minor feature enhancements and lots of bug
876 fixes. All fixes that have been accumulated in the maint branch (in particular
877 those mentionened in the 0.3.6 release notes) appear in this release as well.
880 - new afh option: --human to activate human-readable output.
881 - new server/audiod option: --log-timing to print timing information.
882 - build system improvements.
883 - source code documentation updates.
885 -------------------------------------
886 0.3.6 (2009-12-07) "cubic continuity"
887 -------------------------------------
889 Quite a few bugs have been found and fixed since 0.3.5, so here's
890 another 0.3.x release. No new features.
892 - Always check return value of malloc().
893 - ogg vorbis/FEC: Do not write garbage after the audio file header.
894 - exit if root privileges could not be dropped.
895 - FEC: Fix computation of extra slices.
896 - oss: Fix check for empty input buffer.
897 - Avoid buffer underruns due to filter chain output buffer constraints.
898 - server: Fix assignment of afs_pid.
899 - Don't panic if the afs database contains unknown audio formats.
900 - http/dccp: Do not send the audio file header twice.
901 - FEC: Timing improvements.
903 ----------------------------------------------
904 0.4.0 (2009-11-10) "simultaneous independence"
905 ----------------------------------------------
907 Two significant changes which require the new version number: The
908 improved authentication dialog and the fact that the database code
909 has been moved to a library, libosl. To use the new version, you have
910 to generate new RSA keys, see INSTALL for details. A shell script is
911 provided for conversion of the 0.3 database to the new 0.4 format.
913 - stronger crypto for client authentication
914 - the database code has been moved to a library
915 - improved status item handling
916 - cleanup of the build system
917 - The "-V" option now also prints the git version
918 - the new parser-friendly listing mode for the ls and stat commands
919 - mandatory rc4 encryption
920 - major audio format handler cleanups
921 - (id3,...) tags are no longer stored as a combined string in the database
922 - new mood methods: artist_matches, title_matches, comment_matches,
923 album_matches, year_maches, year.
925 --------------------------------------------
926 0.3.5 (2009-09-21) "symplectic separability"
927 --------------------------------------------
929 Full client support for \*BSD Unixes, complete re-write of the ogg
930 vorbis audio format handler, various improvements all over the place
931 and the usual mix of bugfixes. This release marks the end of the 0.3
932 series if no serious problems show up.
934 - the new oss writer (supported on \*BSD and Linux)
935 - rewrite of the ogg vorbis audio format handler. It's
936 recommended to replace the chunk tables of existing ogg
937 vorbis files in the afs database by re-adding these files
939 - support for netmask subsets (Gerrit Renker)
940 - the new prebuffer filter
941 - improved signal handling
942 - variable fec output buffer size
943 - improved FEC timing fixes audible buffer underruns in UDP mode
944 - --log_color actually works
945 - new ls option: -d (print dates as seconds after the epoch)
946 - update to gengetopt 2.22.2
947 - support for RSA keys of size > 512 bits
948 - new option "mixer_channel" for para_fade
950 -----------------------------------------
951 0.3.4 (2009-05-07) "elliptic inheritance"
952 -----------------------------------------
954 The new udp sender, forward error correction, colored logs and various
955 other improvements. As the udp sender does not depend on any special
956 libraries, it is built unconditionally.
958 - The udp sender replaces the ortp sender. The new code uses forward
959 error correction to protect against packet losses. Many thanks to
960 Gerrit Renker for providing ipv6 support.
961 - The default port for udp streaming now defaults to 8000, like
962 for the http and the dccp senders/receivers.
963 - Loglevels are now specified as symbolic names, e.g.
965 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
966 - para_server/para_audiod: Color support for log messages.
967 - new options for mp3dec: --ignore-crc, --bufsize
968 - new audiod option: --config-file.
969 - gengetopt cleanups.
970 - Improved help/man pages: The documentation of para_audiod,
971 para_recv, para_filter and para_write now also contains
972 all options of the available receivers/filters/writers. The
973 man page of para_fade contains a description of the different
975 - More source code documentation.
978 --------------------------------------------
979 0.3.3 (2008-12-01) "axiomatic perspectivity"
980 --------------------------------------------
982 Internal code cleanups, bug fixes, improved tag handling and the new
983 amplification filter.
985 - para_server uses the generic scheduling code.
986 - overhaul of the virtual streaming system.
987 - mp3: id3 version 2 support via libid3tag (optional)
988 - ogg: vorbis comment support.
989 - aac meta info support.
990 - mp3 audio format handler cleanups.
991 - new filter: "amp" to amplify the amplitude of the audio stream
992 - new status item/database entry: amplification. It is
993 used by the amp filter to pre-amplify the audio stream.
994 - fix a close-without-open bug in para_write.
995 - fix a bug in com_init() which was introduced in 0.3.2.
996 - better error diagnostics for para_client.
998 -----------------------------------------
999 0.3.2 (2008-04-11) "probabilistic parity"
1000 -----------------------------------------
1002 The new para_afh executable, scheduling and documentation improvements.
1004 - new ls option: -lc (list chunk table)
1005 - new executable: para_afh, the stand-alone audio file handler tool
1006 - afs commands can send output more than SHMMAX (32MB on Linux). This
1007 also reduces the memory usage of commands that produce large amounts
1009 - major scheduler and audiod cleanups.
1010 - more detailed and much nicer man pages.
1012 ---------------------------------------
1013 0.3.1 (2008-02-23) "liquid interaction"
1014 ---------------------------------------
1016 A mix of cleanups, bug fixes, improvements, and some new features. No
1017 significant changes to the new database (osl) code, which is generally
1020 - Share some similar/duplicate code between the http and the
1022 - Generic access control lists for paraslash senders.
1023 - dccp sender: Access control lists, connection limiting and support
1024 for the allow,deny,on,off,help sender commands.
1025 - The default dccp port changed from 5001 to 8000 (suggested by
1027 - para_server starts even if not all public keys could be loaded.
1028 - Audiod performance improvements.
1029 - fix a bug in the "off" command of the http sender.
1030 - fix some fd and memory leaks.
1031 - Update to gengetopt-2.22.
1033 -------------------------------------
1034 0.3.0 (2008-01-12) "solar saturation"
1035 -------------------------------------
1037 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
1040 Usually one might expect lots of new features AND a big increase in size
1041 for a major release like this.
1043 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
1044 ever. The decrease in size is mostly due to the removal of some
1045 graphical tools (which were only quick hacks anyway). But also the
1046 fact that the mysql code is gone cuts down the size a bit.
1048 Being independent of mysql comes at a cost: The fact that paraslash
1049 now contains its own database (the object storage layer, osl) increases
1050 the (stripped) binary size of para_server by ~50K on i386.
1052 - no more restrictions on unique basenames.
1053 - independent of mysql: The new self-contained object
1054 storage layer (osl) replaces the mysql database.
1055 - New executable para_fsck: Check integrity of osl tables.
1057 - Reliable audio file move/rename detection.
1058 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
1059 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
1061 - the new osl-based audio file selector (afs) replaces the random,
1062 the playlist and the mysql selector of paraslash-0.2.x.
1063 - IPv6 support (thanks to Gerrit Renker).
1064 - paraslash-0.2.x streams are now called "moods". Writing
1065 0.3.x-mood definitions should be both easier and more
1066 powerful than writing 0.2.x-stream definitions.
1067 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
1068 been removed. The world is a better place without them. However,
1069 para_gui is still there.
1070 - afs tracks audio file selection also in playlist mode.
1071 - few easy-to-use afs commands replace the many not-so-easy-to-use
1072 mysql commands (and are available also in playlist mode).
1073 - Improved error subsystem.
1074 - The earth-shaking new logo.
1076 -----------------------------------------
1077 0.2.17 (2007-11-20) "isotropic threshold"
1078 -----------------------------------------
1080 Mainly bugfixes and cleanups in this version which marks the end of
1081 the 0.2.x series if no serious bugs show up after the release.
1083 - mysql_selector: fix a locking bug.
1084 - universal chunk queueing.
1085 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
1087 - be more carful wrt. signed vs. unsigned argument passing.
1088 - cleanup error.h and fix some references to invalid error
1090 - update to gengetopt-2.21.
1091 - update to ortp-0.13.1.
1092 - autoconf: extend checks for headers, library functions and
1093 compiler characteristics.
1094 - Fix streaming of large mp3 files.
1095 - Fix an off-by-one bug in playlist handling.
1097 --------------------------------------
1098 0.2.16 (2007-04-05) "neural discharge"
1099 --------------------------------------
1101 The main change in this release is the major audio format handler
1102 cleanup which removes some similar/duplicate code and makes it easier
1103 to implement plugins for other audio formats. Of course, the usual mix
1104 of other improvements/changes/bugfixes also made it into the release.
1106 - simplified audio format handlers (most of the handling functions
1107 were moved one layer up to the virtual streaming system).
1108 - para_server uses mmap to read audio files
1109 - repositioning of mp3 streams is much faster, in particular for
1110 jumping near the end of large mp3 files.
1111 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
1113 - fix a bug in para_filter that caused decoding of aac files
1114 to start only after a few seconds.
1115 - fix osx_writer hangs
1116 - simplified dccp code (thanks to Gerrit Renker)
1117 - the compress filter works also on big endian systems (ppc)
1119 -----------------------------------------
1120 0.2.15 (2007-02-16) "inductive resonance"
1121 -----------------------------------------
1123 Minor improvements, more documentation and a bunch of bug fixes.
1125 - para_server: The server.users file is only read once on server
1126 startup rather than for each connection
1127 - mp3dec: Fix decoding of corrupt mp3 files
1128 - afs (audio file sender) is now called vss (virtual streaming
1129 system). Consequently, the permission flags specified in
1130 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
1131 become VSS_READ and VSS_WRITE respectively.
1132 - para_audiod/para_filter: Fix a bug that caused the last chunk
1133 of audio data not being written under certain circumstances
1134 - audiod: compute the difference of server time and local time
1136 - para_server/para_audiod: Fix some memory leaks
1137 - documentation improvements
1138 - configure.ac: fix checks for para_krell
1141 -------------------------------------------
1142 0.2.14 (2006-10-15) "transient singularity"
1143 -------------------------------------------
1145 The only major enhancement of this version is the osx writer which completes
1146 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
1147 until now for reasons beyond the scope of this changelog entry.
1149 - new output plugin for Mac Os: the osx writer
1150 - rename configure command line options from --enable-xxx-headers to
1151 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
1152 - configure: new command line options: --with-mad-headers,
1153 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
1154 - some robustness fixes
1155 - dymamic audio format recognition for audiod
1156 - para_server: new command line option: --autoplay_delay
1157 - para_audiod: new command line option: --clock_diff_count
1159 ---------------------------------------
1160 0.2.13 (2006-07-14) "sonic convolution"
1161 ---------------------------------------
1163 A bunch of new features and core changes.
1165 - the new paraslash scheduler, short and sweet.
1166 - Support for m4a/mp4 files via the new aac audio format
1167 handler/filter (requires libfaad).
1168 - each writer has its own command line parser, just like
1169 para_recv and para_filter.
1170 - para_client and para_audioc use the error subsystem
1171 - writers are integrated in para_audiod (currently linux-only)
1172 - para_client is integrated in para_audiod
1173 - random/playlist selector: improved info strings
1174 - new audiod commands: tasks, kill
1175 - update to libortp-0.10.1
1176 - para_fade: wake time defaults to 8 hours from now
1177 - update to autoconf-2.60
1179 ------------------------------------------
1180 0.2.12 (2006-05-12) "oriented abstraction"
1181 ------------------------------------------
1183 Many user-visible changes in this release and lots of new
1186 - the new optional dccp sender/receiver. It uses the datagram
1187 congestion control protocol. You'll need a fairly new kernel
1189 - paraslash works on Mac OS X (thanks to Gerd Becker)
1190 - para_play renamed to para_write
1191 - modular output plugin design (writers) for para_write
1192 - new file_writer output plugin for para_write
1193 - compress filter speed improvements
1194 - update to libortp-0.9.1
1195 - update to gengetopt-2.17rc
1196 - para_client no longer depends on libreadline (as the
1197 code for the interactive mode was removed).
1198 - gcc-2-95 is no longer a supported compiler. It may still
1199 work, but it gets no more testing.
1200 - the tarball no longer contains the screenshot images which
1201 reduces its size quite a bit.
1202 - configure: new command line options: --enable-mysql-headers
1203 and --enable-mysql-libs
1205 ------------------------------------
1206 0.2.11 (2006-03-11) "atomic duality"
1207 ------------------------------------
1209 Here it is, the first paraslash release developed with git. There
1210 are fairly many user-visible changes in this release. As two out of
1211 the three "database tools" of paraslash don't use a database at all,
1212 they are now called "audio file selectors" instead.
1214 - the cdt command (change database tool) becomes chs (change
1216 - no more colon separators: The syntax of some options of
1217 para_audiod and para_filter have changed. Use --help for
1218 more info (and some examples).
1219 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
1220 - switch from cvs to git (should've done that earlier)
1221 - the new ipc subsystem
1222 - new audio file selector: playlist
1223 - para_server: the dopey selector is now called "random",
1224 and is the default selector. Use the --selector option to
1225 choose another selector at startup, or the chs command to
1226 change the selector at runtime.
1227 - X86_64 fixes (thanks to Steffen Klassert)
1230 --------------------------------------
1231 0.2.10 (2006-02-17) "cyclic attractor"
1232 --------------------------------------
1234 Huge documentation update, a scrollable window for para_gui, ortp
1235 improvements, and of course many small fixes not mentioned here.
1236 The diffstat below is rather misleading as most insertions are due
1237 to the new source documentation.
1240 - para_server also uses the new error subsystem
1241 - lots of new documentation (UTSL)
1243 - keysyms for cursor keys and for next/previous page keys
1244 - scrollable output window
1245 - new internal commands: scroll up/down, page up/down
1246 - fix color of command output.
1247 - ortp: the --chunk_time and --header flags are no longer needed
1248 for para_recv/para_audiod as this information is now encoded in
1249 each rtp packet sent by para_server.
1251 -------------------------------------------
1252 0.2.9 (2006-01-24) "progressive turbulence"
1253 -------------------------------------------
1255 Internal audiod receivers/filters, the new error subsystem and
1256 a lot of small improvements.
1258 - para_recv and para_filter are integrated into the para_audiod
1259 binary, i.e. audiod no longer spawns a new process for
1260 each receiver/filter. As para_recv and para_filter might be
1261 useful as standalone programs, they still get built (linked
1262 against the same object files that are also used for audiod).
1263 - further ortp timing improvements should reduce the CPU usage
1264 of the ortp receiver.
1265 - improved audio grabbing. The 'grab' command of para_audiod
1266 has its own set of command line options. Read the output of
1267 "para_audioc help grab" for more info.
1268 - oggdec: configurable input prebuffer size.
1269 - the new error subsystem gives better error diagnostics
1270 and reduces code size.
1272 -----------------------------------------
1273 0.2.8 (2006-01-02) "dynamic accumulation"
1274 -----------------------------------------
1276 The new modular filter design and the para_play-hangs bugfix.
1278 - new executable: para_filter. It combines para_mp3dec,
1279 para_oggdec and para_compress. It also adds a further filter
1280 type, wav, that just inserts a wave header at the desired point
1281 of the filter chain. All 'piping' is done in-memory (i.e. no
1282 read/write operations are used).
1283 - para_play: fix a stupid bug that caused it to hang under
1284 certain circumstances.
1286 -------------------------------------------
1287 0.2.7 (2006-12-27) "transparent invariance"
1288 -------------------------------------------
1290 Not many user-visible changes but a fair amount of internal improvements.
1292 - The http sender buffers data if it can not be sent
1293 out immediately (because the socket is not writable). This
1294 should prevent para_server from shutting down the connection
1295 too early on a loaded network.
1296 - para_play also prebuffers data if it is told to start at a
1297 future time by the --start_time option.
1298 - The return of para_recv: It combines para_ortp_recv and
1299 para_http_recv. Use the --receiver option to switch between
1300 the two. para_recv builds without libortp, but contains
1301 only the http receiver in this case.
1302 - update to ortp 0.8.1. As this ortp release contains incompatible
1303 changes, para_recv-0.2.7 won't link against older ortp libs.
1304 - improved ortp timings.
1305 - use of gcc-extensions that #define away for non-gcc and
1308 -------------------------------------------
1309 0.2.6 (2005-10-29) "recursive compensation"
1310 -------------------------------------------
1312 Transparent session encryption (uses openssl's Alleged RC4 cipher),
1313 the internal find command and several other improvements and cleanups.
1315 - Encrypt the session if encryption is requested by the client
1316 (default for para_client 0.2.6). This is backwards
1317 compatible, so older clients can still connect to para_server
1318 0.2.6. Use the new client option --plain to request an
1319 uncrypted session (off by default, must be set to on in
1320 order to connect to para_server 0.2.x with 0 <= x <= 5).
1321 - para_server uses an internal function to locate audio files
1322 rather than calling find(1). The server option
1323 --mysql_audio_file_dir replaces --mysql_find_cmd.
1324 - documentation update
1326 - header file cleanup
1327 - para_client code cleanup
1328 - para_gui: faster display of output of display commands
1330 ------------------------------------------
1331 0.2.5 (2005-10-13) "aggressive resolution"
1332 ------------------------------------------
1334 This release adds internal senders, i.e. no more external programs are
1335 spawned for sending out the audio data. There are two different senders
1336 available: The http sender and the ortp sender (former para_send which
1337 is no longer needed).
1339 The new sender code has a plugin-like design so it can be easily
1340 extended should there be be any future need for supporting another
1341 network streaming protocol. All senders are completely independent of
1342 each other. In particular, the http and the ortp sender can operate
1345 - new server command: sender to control senders at runtime.
1346 Read the output of "para_server -h" and "para_client help
1347 sender" for more information.
1348 - para_recv renamed to para_ortp_recv
1349 - new executable: para_http_recv, a simple command line
1351 - major afs/mp3/ogg code simplifications due to internal
1353 - ogg timing improvements
1354 - fix several minor memory leaks (found by valgrind)
1355 - empty stream definitions work again
1356 - com_ne(): ignore errors on remove
1357 - audiod: fix segfault on server restart
1359 ---------------------------------------
1360 0.2.4 (2005-09-21) "toxic anticipation"
1361 ---------------------------------------
1363 Several small improvements, fixes and the new grab command.
1366 - new command: "grab" to grab the output of the stream reader
1367 or any filters. Read the output of "para_audioc help grab"
1368 for more information.
1371 - audioc: new command line option: --bufsize to specify a
1372 buffer size different from the default size 8192.
1373 - improved error diagnostics for para_play.
1374 - new configure option: --enable-ssldir so search for openssl in
1376 - sdl_gui: Make it look nice again for 1024x768
1377 - server: report total size of memory allocated with sbrk by malloc,
1378 new command line option: --announce_time
1380 -----------------------------------------
1381 0.2.3 (2005-09-01) "hydrophilic movement"
1382 -----------------------------------------
1384 Two new executables and major feature enhancements.
1386 - audiod filters: It is now possible to specify arbitrary many
1387 (including none) filters for each supported audio
1388 format. This can be used e.g. for normalizing volume,
1389 transforming or grabbing the audio stream, or for using
1390 visualizers. Read the output of "para_audiod -h" for the
1391 syntax of the new --filter_cmd option.
1392 - new executable: para_play, a tiny alsa player. It
1393 can play wave files or raw pcm (16 bit little endian)
1395 - new executable: para_compress, a dynamic range compressor
1396 intended to keep audio output at a consistent volume. Derived
1397 from [AudioCompress](http://trikuare.cx/code/AudioCompress.html).
1398 - audiod: New option: --stream_delay. This can be used in
1399 a local network to syncronize the audio output of all
1400 clients that play the same stream.
1402 ------------------------------------------
1403 0.2.2 (2005-08-19) "tangential excitation"
1404 ------------------------------------------
1406 Mostly internal changes in this release, but also some new commands
1407 for the mysql database tool.
1409 - cleanup exec.c, fix para_exec bug
1410 - compile time loglevel (log messages below the given level
1411 won't be compiled in, which reduces the size of the
1413 - new log macros that shorten the size of the source code.
1414 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
1415 to send only zeros. With this workaround, para_audioc works
1417 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
1418 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
1419 (new entry), "snp" (set numplayed). Read the manual for more
1422 ---------------------------------------
1423 0.2.1 (2005-08-15) "surreal experience"
1424 ---------------------------------------
1426 Here comes paraslash-0.2.1. It contains a couple of new features and,
1427 surprise, only minor bug fixes.
1429 - kill noisy mp3 debug message
1430 - cleanup of the build system
1431 - para_server and para_client directly use the crypto routines
1432 of the openssl library rather than invoking the openssl command
1434 - server/audiod: new option --user to switch to the given user
1435 when invoked as root. Read the output of "para_server -h" for
1437 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
1438 status. Default: "para_audioc stat"
1439 - sdl_gui: new option --pic_cmd to be used to download the picture.
1440 Default: "para_client pic"
1441 - audiod: 5 slots ought to be enough for everybody
1442 - audiod: new status item: Uptime, kill hup command
1444 ------------------------------------------
1445 0.2.0 (2005-08-06) "distributed diffusion"
1446 ------------------------------------------
1448 After several month of increased development activity, paraslash-0.2.0
1449 has arrived. It contains many new features and is much more
1450 self-contained than the old 0.1.x series. Enjoy!
1452 - para_server: fix hang on song change and crash on sighup.
1453 Speed up mysql queries. The DIR_LIKE macro is gone.
1454 - new executables: para_audiod, the local audio daemon that
1455 starts playback (uses SCM_CREDENTIALS socket magic) and
1456 para_audioc, the corresponding client.
1457 - new executables: para_mp3dec/para_oggdec, two really teensy
1458 decoders. para_mp3dec is based on libmad, para_oggdec requires
1460 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
1461 they are now called para_send and para_recv respectively.
1462 - documentation updates
1463 - para_gui is themable. For now there is the default theme that
1464 looks as before and the simple theme: blue and easy.
1465 - gui: audio streaming is now handled by audiod. Time display shows
1466 playback time rather than streaming time
1467 - slider: update to libzmw-0.2.0
1468 - para_krell: fix crash on server shutdown
1469 - switch from gzip to bzip2
1471 ----------------------------------------
1472 0.1.7 (2005-04-18) "melting penetration"
1473 ----------------------------------------
1475 The main change in this release is clearly the oggvorbis rewrite,
1476 but there are also lots of smaller changes. If you intend to use both
1477 the mp3 and the ogg plugin, it is recommended to use software mixing,
1478 e.g. the dmix plugin which is provided by ALSA.
1480 - new executables: para_ovsend and para_ovrecv for sending/receiving
1481 oggvorbis files via rtp. Requires the open rtp library. Get it at
1482 http://www.linphone.org/ortp/
1483 - rewrite of the ogg_vorbis core code
1484 - configure detects libzmw and, if detected, includes
1485 para_slider to the list of binaries to be built by make
1486 - server stream writers read from their associated fifo rather
1488 - slider: two new sliders, lastplayed and numplayed
1489 - fix nasty double free bug which caused random segfaults in case of
1490 mp3 files with invalid header information
1491 - gui: new command line option: --stream_timeout=seconds to
1492 deactivate a slot if it is idle for that many seconds (default=`5')
1495 ---------------------------------------
1496 0.1.6 (2005-03-05) "asymptotic balance"
1497 ---------------------------------------
1499 Only little user-visible changes in this release. Mainly bugfixes and
1500 core code cleanup. This is probably the most stable version ever if you
1503 - fix several memory leaks
1504 - rename default name of mysql database from "music" to "paraslash".
1505 Use para_server's --mysql_database option if you do not want to
1506 rename your old database.
1507 - rework ogg vorbis code
1508 - make update command work on mysql servers with LOCAL_INFILE
1510 - gui: improved stream I/O (slots)
1511 - simplified audio format API
1512 - para_pob_ogg is gone
1514 ------------------------------------
1515 0.1.5 (2004-12-31) "opaque eternity"
1516 ------------------------------------
1518 Let's slide gently into the new year.
1520 - new: para_slider (not built automatically, type "make
1521 para_slider" to build). A toy for those who always felt that
1522 creating stream definitions is difficult. See screenshots,
1523 README and FEATURES for more info.
1524 - improved signal handling. Fixes server segfault on SIGHUP
1525 for linux kernels newer than Aug 24 2004 and makes para_gui
1527 - reload database tool on SIGHUP
1528 - improved help message for sl
1529 - do not log "broken pipe" messages as errors. They are
1531 - fix wrong error message on permission errors
1533 -----------------------------------------
1534 0.1.4 (2004-12-19) "tunneling transition"
1535 -----------------------------------------
1537 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1538 Hopefully, most of them got wiped out with this release. Some
1539 enhancements went also in.
1541 - improved error diagnostics for all commands
1542 - stradd/picadd: overwrite previous contents if entry already
1543 exists, rather than returning errors
1544 - stradd: use current stream if invoked without args
1545 - faster (and hopefully more stable) ogg-vorbis handling
1546 - para_krell: reap children to avoid zombie-flooding in case
1547 no server is running
1548 - si: report also server pid
1549 - server: don't busy-loop if dbtool reports only invalid files.
1550 - gui: CTRL+C works again, fix stream_read command line option
1552 - fix mysql dbtool startup in case no database exists
1553 - many small fixes and cleanups
1555 ---------------------------------------
1556 0.1.3: (2004-12-10) "vanishing inertia"
1557 ---------------------------------------
1559 Starting from this release, the database tools are integrated in the
1560 server binary. This decreases server startup time, reduces code size
1561 and speeds up database commands. However, the layout of the underlying
1562 mysql database changed only slightly and 0.1.3 should be backwards
1563 compatible in that respect.
1567 - If mysql is not detected at compile time, or fails to init
1568 at runtime, fall back to the dopey database tool which should
1570 - para_dbtool and dbtool.conf are gone. All mysql specific
1571 options are read from server.conf and are prefixed by 'mysql_'.
1572 - new command: cdt (change database tool)
1573 - new command line option: dbtool (choose startup database tool)
1574 - The name of current stream is now stored in the database,
1575 so paraslash remembers its current stream when restarted.
1576 - new command: csp (change stream and play)
1577 - para_gui also reports current database tool and server uptime
1579 -------------------------------------------
1580 0.1.2: (2004-11-28) "spherical fluctuation"
1581 -------------------------------------------
1583 Point release before the big dbtool changes go in.
1585 - dbtool: rename ca to cam (copy all meta data). It now also
1586 copies numplayed and lastplayed time as well as the picture
1588 - fix endless-loop-bug caused by mp3 files with invalid header
1590 -----------------------------------------
1591 0.1.1: (2004-11-05) "floating atmosphere"
1592 -----------------------------------------
1595 - new dbtool command: mbox. Browse your sound-file collection
1596 with your favorite mail reader.
1597 - several small fixes
1599 -------------------------------------
1600 0.1.0: (2004-10-22) "rotating cortex"
1601 -------------------------------------
1603 - fix logging bug for loglevel > VERBOSE
1605 - correct timings for vbr mp3s
1606 - modular audio format support
1607 - ogg-vorbis support (experimental)
1608 - new server option: autoplay
1610 -----------------------------------------
1611 0.0.99: (2004-07-25) "harmonic deviation"
1612 -----------------------------------------
1614 - rename projectname from icc to paraslash (play, archive, rate
1615 and stream large audio sets happily)
1616 - paraslash is no longer restricted to one particular audio
1618 - new dbtool commands (stradd, strq, strdel) for easy stream
1619 managment w/o configuration file. That obsoletes stream_defs
1620 file/config option for dbtool.
1621 - picadd accepts jpeg data from stdin
1622 - new server commands: ps (select previous stream), sc (song change)
1623 - new default pictures for sdl_gui
1624 - gui: new key_map option for binding commands and internal
1625 functions to arbitrary keys, nice help screen, rip out
1626 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1627 show silly logo on startup
1628 - new executables: para_fade for fading volume, para_dbadm for
1629 manipulating attributes
1630 - cdb adds _all_ tables to mysql database
1631 - revised and beautified documentation
1632 - sample dbtool rewritten in C
1635 ---------------------------------------------
1636 0.0.98: (2003-12-26) "incremental smoothness"
1637 ---------------------------------------------
1639 - kick icecast in favour of poc. That removes some races and reduces
1640 core code considerably.
1641 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1642 give finer info on afs' status.
1643 - gui can start decoder (see config options). Further new gui
1644 commands: refresh (^L), jmp (F1-F10)
1645 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1646 terminates gui. This fixes dead instances consuming memory
1648 - new dbtool command: verb for sending verbatim sql queries.
1649 - fix pid_list races (by removing pid_list)
1652 --------------------
1653 0.0.97: (2003-10-26)
1654 --------------------
1656 - installation prefix now defaults to /usr/local
1657 - new commands for gui: snozze, sleep and reread config
1658 - config file for gui and sdl_gui
1659 - fix problems with filenames containing funny characters
1660 (reported by Thomas Forell)
1661 - improved signal handling for gui, now it rereads conf on SIGHUP
1662 - new dbtool command: cdb (create database)
1663 - switch from argtable to gengetopt
1664 - major code cleanup and speed improvements
1665 - fix several potential buffer overflows
1666 - many small fixes and cleanups
1672 - easy stream_defs syntax
1673 - sdl_gui can display images associated to the file being played
1674 - Major feature enhancements for icc_gui including dynamic text
