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

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

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

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

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

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

203 0.5.8 (2017-09-23) "branching parabola"
204 ---------------------------------------
206 A couple of fixes for serious old bugs have accummulated in the maint
207 branch since paraslash-0.5.7 was released nine months ago. So here
208 is another 0.5.x release. As usual, all commits in the maint branch
209 have been merged into master, so the upcoming paraslash-0.6.1 also
210 contains them. For details see the git log.

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

289 0.5.7 (2016-12-31) "semantic density"
290 -------------------------------------
292 Mostly a bug fix release, and a bunch of internal improvements.
293 The only user-visible changes are the sanity checks for the touch
294 command and the new options to the ls command.
296 - Speedup of the base64 decoder.
297 - One of the two source browsers has been removed from the web pages.
298 The doxygen API reference still contains an HTML version of each
300 - Two race conditions in para_server have been fixed.
301 - ls -p is now deprecated in favor of -F or -b. See the help text of
302 the ls command for details.
303 - The openssl code has been adjusted to work also with openssl-1.1.
304 - The wma decoder and audio format handler now correctly decodes
305 files with unusual block sizes.
306 - We now compile with -Wformat-signedness if possible.
307 - The touch command now refuses to set an invalid image or lyrics ID.
308 - New section on contributing for the user manual.
309 - Major simplification of the error subsystem.

316 0.4.14 (2016-12-31) "branching oscillation"
317 -------------------------------------------
319 Many fixes for nasty bugs have accumulated over the years since 0.4.13
320 was released in 2013. This release contains all of them. It is the
321 last v0.4.x release, so v0.4.x is now end of life. The maint branch
322 of the git repository has been forwarded to v0.5.7 and will start to
323 receive important fixes for 0.5.x, which is now in maintenance mode.
325 - Fix for the "double encryption bug" with gcrypt, which caused
326 garbage to be sent to stat clients.
327 - The "prev" command of para_play now works as expected.
328 - Invalid parameters for the begin and end chunk no longer cause
329 the afh receiver of para_recv to segfault.
330 - A fix for an assertion that triggered in the FEC slice setup code.
331 - Closing the terminal with a running para_gui causes the process to
332 die, rather than using 100% of CPU time.
333 - para_gui no longer shows stale information about the previous
335 - A fix for a bug in the fec decoder which caused aborts if the buffer
337 - The assertion in the buffer tree code no longer triggers.

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

352 The highlight of this release is the new -m flag for para_afh which
353 lets it modify the meta tags of the given audio file(s). This feature
354 is supported for all audio formats. Many small cleanups and bug fixes
355 not mentioned here have accumulated and are also part of the release.
357 - para_afh learned to modify meta tags of mp3 wma ogg spx
359 - afs commands propagate error codes to the client.
360 - The check command now also checks the attribute table for
362 - New -v flag for the version command (print verbose version string)

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

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

485 - Cleanup of the mood subsystem.
486 - Fixes and cleanups for the flac decoder.
487 - Latency improvements for the ogg/opus decoder.
488 - Crypto support is now optional. On systems without
489 openssl/gcrypt, the build succeeds but para_server,
490 para_audiod, para_client won't be built.
491 - The build system now works for cross-compile setups.
492 - The dependency tree has been flattened, which speeds up
493 builds and avoids to recreate the man pages on every change.
494 - The error code helper has been rewritten from perl to C,
495 which further improves build time.
496 - Many small bugs in the build system have been identified

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

533 One more 0.4.x release before the API-breaking changes for 0.5.0 go
534 in. The main features of this release are the ogg/opus audio format,
535 and UTF-8 support, but it includes also tons of other improvements
536 and fixes all over the place.
538 - New audio format: ogg/opus.
539 - UTF8 support for para_gui and the mp3 audio format handler.
540 - Scheduler improvements and fixes.
541 - The obsolete gettimeofday() function has been replaced
542 by clock_gettime() on systems which support it.
543 - Speed and usability improvements for para_gui.
544 - para_client now restores the fd flags of stdin and stdout
546 - Improved manual pages.
547 - Consistent version strings for all executables.
548 - Reduced dependencies on generated files result in fewer
549 recompilations on changes.

557 para_fade, and the improved build system are the highlights of this
558 release which probably marks the end of the 0.4.x series.
560 - The afh receiver and the para_play executable.
561 - The resample filter: A sample rate converter based on
563 - The "versions" directory has been removed from the master
564 branch. The tarballs of the old releases are now available
565 in the new "releases" branch.
566 - Overhaul of the build system: All generated files are now
567 written to the "build" directory.
568 - The modular mixer API and the alsa mixer.
569 - Minor fixes for the osx writer.
571 --------------------------------------
572 0.4.11 (2012-07-20) "mutual diversity"
573 --------------------------------------
575 The major feature in this release is the new sideband API for
576 client-server communication. This API will be used exclusively starting
577 with 0.5.0, which breaks backward compatibility but allows to get rid
578 of quite some compatibility code. Other noteworthy changes include
579 decoder latency improvements and a long-standing bug fix for the
582 - Sideband connections: If both para_server and para_client
583 support this feature, data is sent as a multiplexed stream.
584 - The --no_default_filters option of para_filter has been
586 - Several fixes and latency improvements to various decoders.
587 - The ALSA writer now limits the prebuffer time to 500ms.
588 - Documentation improvements.
589 - Overhaul of the command_util.sh script.
590 - Fixes for some minor problems found by the clang analyzer.
591 - Compiles (almost) without warnings on gcc-3.
592 - Robustness improvements of the buffer tree code.
594 ------------------------------------------
595 0.4.10 (2012-03-30) "heterogeneous vacuum"
596 ------------------------------------------
598 Nothing earth-shaking in this release, but quite a few usability
599 improvements and the usual mix of cleanups and fixes.
601 - The --no_default_filters option of para_filter has been
602 deprecated. It still works but has no effect and will be
603 removed in the next version.
604 - para_gui now prints also the stderr output of the executing
605 command in the bottom window.
606 - Cleanup and consolidation of the various wrappers for
607 write(), writev(), send() and friends.
608 - The obscure error messages on mmap() failures have been
609 replaced by meaningful messages. This affects mainly
611 - para_audioc: Cleanups and memory leak fixes.
612 - Test 0004-server no longer fails if para_server is not
614 - New configure options: --with-id3tag-{headers,libs}.
616 -------------------------------------
617 0.4.9 (2011-12-06) "hybrid causality"
618 -------------------------------------
620 Support for another audio format, interactive mode for para_client
621 and para_audiod and many small improvements/fixes all over the place.
623 - Support for flac, the free lossless audio codec.
624 - Fix for an endless loop in the mp3 decoder for certain
626 - When executed without specifying a command, para_client
627 and para_audioc start an interactive shell (requires
628 libreadline being installed). The interactive mode offers
629 full tab completion and command line history.
630 - autogen.sh now detects a distcc setup and adjusts the
631 parameter for the -j option of make accordingly.
632 - Shared memory areas are no longer restricted to 64K. We now
633 detect the maximal size of a shared memory area at runtime.
634 - cleanup of the internal uptime API.
635 - para_server prefaults the mmapped audio file to avoid
636 delays on slow media.
637 - A new test for the test-suite that exercises the
638 communication between para_server and para_audiod.
639 - The alsa writer eats up less CPU cycles when configured to
641 - Simplified and unified receiver code.
643 - Commands which print a list of matching audio files now
644 emit a meaningful error message if no audio file matched the
647 --------------------------------------
648 0.4.8 (2011-08-19) "nested assignment"
649 --------------------------------------
651 Gcrypt support, the overhauled osx writer and regex format specifiers
652 are the highlights of this release.
654 - support for libgcrypt as a drop-in replacement for openssl.
655 Run configure --enable-cryptolib=gcrypt to link against
656 libgcrypt. The two crypto implementations are compatible to
657 each other, i.e. a para_client executable linked against
658 gcrypt can connect to para_server linked against libssl
660 - Rewrite of the osx writer (output plugin for Mac OS).
661 - audiod: The format specifier for receivers, filters and
662 writers is now treated as a regular expression. This allows
663 to replace 5 lines in the config file (one for each audio
664 format) by one single line. See the manual for details.
665 - The \*.cmdline.[ch] files are no longer contained in the released
666 tarballs. This reduces the size of the tarballs but requires
667 gengetopt to build the tarball.
668 - Compiles cleanly also with llvm/clang.
669 - Corrupt mp3 files are handled more gracefully.
670 - The alsa writer uses poll fds instead of computing timeouts.
671 - Cleanup of the generic writer API.
672 - sched: Optimized zero timeouts.
673 - vss timeout cleanups.
674 - oggdec fixes and improvements.
676 --------------------------------------
677 0.4.7 (2011-06-01) "infinite rollback"
678 --------------------------------------
680 The new ao writer, support for ssh RSA keys and a couple of other
683 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
684 platforms through the libao audio library.
685 - Support for RSA keys generated with ssh-keygen.
686 - configure: improved options for ogg/vorbis/speex.
687 - The git version reported by --version always matches HEAD.
688 - The autogen script detects the number of processors and
689 runs a parallel make if possible.
690 - Major cleanup of the crypto API.
691 - Documentation updates.
693 ------------------------------------------
694 0.4.6 (2011-03-31) "deterministic entropy"
695 ------------------------------------------
697 Lots of ogg/vorbis improvements, the new test suite, enhancements
698 for para_gui and a fair amount of other bug fixes.
700 - For DCCP/OGG streams the audio file header is only sent once
701 at the beginning of the stream rather than periodically
702 every five seconds. This reduces network traffic and the
704 - The vorbis comment header is replaced by an empty dummy header
705 before the header is sent over the network. This also results in
706 less network traffic and smaller FEC groups.
707 - The new "test" make target allows to perform some sanity checks prior
708 to installing the package.
709 - ogg timing fixes and performance improvements
710 - Scheduler improvements
711 - Proper exit codes for para_write
712 - para_gui: New option --theme to select a startup theme. Several
713 other improvements and fixes.
714 - aacdec error message cleanups
715 - simplified color error handling
717 --------------------------------------------
718 0.4.5 (2010-12-17) "symmetric randomization"
719 --------------------------------------------
721 Bug fixes, internal cleanups and variable-sized FEC slices.
723 - Contains a fix for an invalid-free-bug in the ogg audio format
725 - Switching off the DCCP sender works again.
726 - para_audiod handles crashes of para_server more robustly.
727 - Internal scheduler and writer cleanups.
728 - Reduced latency due to variable-sized FEC slices.
729 - Improved documentation and error diagnostics.
730 - The build of para_server is now optional, allowing the build
731 to succeed in case libosl is not installed.
733 ------------------------------------------
734 0.4.4 (2010-08-06) "persistent regularity"
735 ------------------------------------------
737 Support for yet another audio format, para_write improvements and
740 - Support for the speex codec.
741 - Support for sample formats other than 16 bit little endian.
742 - error2.h is now created by a perl script which speeds up configure
744 - Fix a bug in the aac decoder which could lead to segfaults in
745 para_filter/para_audiod.
746 - Fixes for autoconf-2.66.
748 ----------------------------------------
749 0.4.3 (2010-07-05) "imaginary radiation"
750 ----------------------------------------
752 Many improvements for the DCCP and the UDP transport, the new user
753 manual and the usual mix of bug fixes and internal improvements.
755 - FEC support for the DCCP sender (Gerrit Renker). The new
756 --dccp_max_slice_size, --dccp_data_slices_per_group and
757 --dccp_slices_per_group options can be used to set the FEC
758 parameters for the DCCP transport.
759 - DNS lookups for UDP targets (Gerrit Renker).
760 - The new user manual replaces the README, README.afs, REQUIREMENTS
761 and INSTALL documents.
762 - Fix an end-of-file detection bug in the oggdec filter.
763 - The new nonblock API.
764 - Both options of the oggdec filter have been removed.
765 - New debug mode for the internal scheduler.
767 ------------------------------------------
768 0.4.2 (2010-04-23) "associative expansion"
769 ------------------------------------------
771 It's been some time since the last release, but finally here is
772 paraslash-0.4.2. The bulk of the changes comes from the new buffer
773 tree API, but there are changes all over the tree. Mainly performance
774 and usability improvements, but also quite some bug fixes.
776 - The new buffer tree API.
777 - DCCP: Support for CCID negotiation (Gerrit Renker).
778 - UDP robustness fixes.
779 - The --bufsize option for mp3dec is gone as it no longer makes sense
780 for the new buffer tree API.
781 - Fix audible buffer underruns for wma streams.
782 - The alsa writer no longer prints meaningless underrun durations.
783 - audiod: Defaults work also for udp streams. If no filter is
784 given for an audio format that is received via upd, fecdec is
785 automatically added as the first filter (along with the decoder).
787 ---------------------------------------
788 0.4.1 (2009-12-22) "concurrent horizon"
789 ---------------------------------------
791 Support for another audio format, minor feature enhancements and lots of bug
792 fixes. All fixes that have been accumulated in the maint branch (in particular
793 those mentionened in the 0.3.6 release notes) appear in this release as well.
796 - new afh option: --human to activate human-readable output.
797 - new server/audiod option: --log-timing to print timing information.
798 - build system improvements.
799 - source code documentation updates.
801 -------------------------------------
802 0.3.6 (2009-12-07) "cubic continuity"
803 -------------------------------------
805 Quite a few bugs have been found and fixed since 0.3.5, so here's
806 another 0.3.x release. No new features.
808 - Always check return value of malloc().
809 - ogg vorbis/FEC: Do not write garbage after the audio file header.
810 - exit if root privileges could not be dropped.
811 - FEC: Fix computation of extra slices.
812 - oss: Fix check for empty input buffer.
813 - Avoid buffer underruns due to filter chain output buffer constraints.
814 - server: Fix assignment of afs_pid.
815 - Don't panic if the afs database contains unknown audio formats.
816 - http/dccp: Do not send the audio file header twice.
817 - FEC: Timing improvements.
819 ----------------------------------------------
820 0.4.0 (2009-11-10) "simultaneous independence"
821 ----------------------------------------------
823 Two significant changes which require the new version number: The
824 improved authentication dialog and the fact that the database code
825 has been moved to a library, libosl. To use the new version, you have
826 to generate new RSA keys, see INSTALL for details. A shell script is
827 provided for conversion of the 0.3 database to the new 0.4 format.
829 - stronger crypto for client authentication
830 - the database code has been moved to a library
831 - improved status item handling
832 - cleanup of the build system
833 - The "-V" option now also prints the git version
834 - the new parser-friendly listing mode for the ls and stat commands
835 - mandatory rc4 encryption
836 - major audio format handler cleanups
837 - (id3,...) tags are no longer stored as a combined string in the database
838 - new mood methods: artist_matches, title_matches, comment_matches,
839 album_matches, year_maches, year.
841 --------------------------------------------
842 0.3.5 (2009-09-21) "symplectic separability"
843 --------------------------------------------
845 Full client support for \*BSD Unixes, complete re-write of the ogg
846 vorbis audio format handler, various improvements all over the place
847 and the usual mix of bugfixes. This release marks the end of the 0.3
848 series if no serious problems show up.
850 - the new oss writer (supported on \*BSD and Linux)
851 - rewrite of the ogg vorbis audio format handler. It's
852 recommended to replace the chunk tables of existing ogg
853 vorbis files in the afs database by re-adding these files
855 - support for netmask subsets (Gerrit Renker)
856 - the new prebuffer filter
857 - improved signal handling
858 - variable fec output buffer size
859 - improved FEC timing fixes audible buffer underruns in UDP mode
860 - --log_color actually works
861 - new ls option: -d (print dates as seconds after the epoch)
862 - update to gengetopt 2.22.2
863 - support for RSA keys of size > 512 bits
864 - new option "mixer_channel" for para_fade
866 -----------------------------------------
867 0.3.4 (2009-05-07) "elliptic inheritance"
868 -----------------------------------------
870 The new udp sender, forward error correction, colored logs and various
871 other improvements. As the udp sender does not depend on any special
872 libraries, it is built unconditionally.
874 - The udp sender replaces the ortp sender. The new code uses forward
875 error correction to protect against packet losses. Many thanks to
876 Gerrit Renker for providing ipv6 support.
877 - The default port for udp streaming now defaults to 8000, like
878 for the http and the dccp senders/receivers.
879 - Loglevels are now specified as symbolic names, e.g.
881 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
882 - para_server/para_audiod: Color support for log messages.
883 - new options for mp3dec: --ignore-crc, --bufsize
884 - new audiod option: --config-file.
885 - gengetopt cleanups.
886 - Improved help/man pages: The documentation of para_audiod,
887 para_recv, para_filter and para_write now also contains
888 all options of the available receivers/filters/writers. The
889 man page of para_fade contains a description of the different
891 - More source code documentation.
894 --------------------------------------------
895 0.3.3 (2008-12-01) "axiomatic perspectivity"
896 --------------------------------------------
898 Internal code cleanups, bug fixes, improved tag handling and the new
899 amplification filter.
901 - para_server uses the generic scheduling code.
902 - overhaul of the virtual streaming system.
903 - mp3: id3 version 2 support via libid3tag (optional)
904 - ogg: vorbis comment support.
905 - aac meta info support.
906 - mp3 audio format handler cleanups.
907 - new filter: "amp" to amplify the amplitude of the audio stream
908 - new status item/database entry: amplification. It is
909 used by the amp filter to pre-amplify the audio stream.
910 - fix a close-without-open bug in para_write.
911 - fix a bug in com_init() which was introduced in 0.3.2.
912 - better error diagnostics for para_client.
914 -----------------------------------------
915 0.3.2 (2008-04-11) "probabilistic parity"
916 -----------------------------------------
918 The new para_afh executable, scheduling and documentation improvements.
920 - new ls option: -lc (list chunk table)
921 - new executable: para_afh, the stand-alone audio file handler tool
922 - afs commands can send output more than SHMMAX (32MB on Linux). This
923 also reduces the memory usage of commands that produce large amounts
925 - major scheduler and audiod cleanups.
926 - more detailed and much nicer man pages.
928 ---------------------------------------
929 0.3.1 (2008-02-23) "liquid interaction"
930 ---------------------------------------
932 A mix of cleanups, bug fixes, improvements, and some new features. No
933 significant changes to the new database (osl) code, which is generally
936 - Share some similar/duplicate code between the http and the
938 - Generic access control lists for paraslash senders.
939 - dccp sender: Access control lists, connection limiting and support
940 for the allow,deny,on,off,help sender commands.
941 - The default dccp port changed from 5001 to 8000 (suggested by
943 - para_server starts even if not all public keys could be loaded.
944 - Audiod performance improvements.
945 - fix a bug in the "off" command of the http sender.
946 - fix some fd and memory leaks.
947 - Update to gengetopt-2.22.
949 -------------------------------------
950 0.3.0 (2008-01-12) "solar saturation"
951 -------------------------------------
953 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
956 Usually one might expect lots of new features AND a big increase in size
957 for a major release like this.
959 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
960 ever. The decrease in size is mostly due to the removal of some
961 graphical tools (which were only quick hacks anyway). But also the
962 fact that the mysql code is gone cuts down the size a bit.
964 Being independent of mysql comes at a cost: The fact that paraslash
965 now contains its own database (the object storage layer, osl) increases
966 the (stripped) binary size of para_server by ~50K on i386.
968 - no more restrictions on unique basenames.
969 - independent of mysql: The new self-contained object
970 storage layer (osl) replaces the mysql database.
971 - New executable para_fsck: Check integrity of osl tables.
973 - Reliable audio file move/rename detection.
974 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
975 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
977 - the new osl-based audio file selector (afs) replaces the random,
978 the playlist and the mysql selector of paraslash-0.2.x.
979 - IPv6 support (thanks to Gerrit Renker).
980 - paraslash-0.2.x streams are now called "moods". Writing
981 0.3.x-mood definitions should be both easier and more
982 powerful than writing 0.2.x-stream definitions.
983 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
984 been removed. The world is a better place without them. However,
985 para_gui is still there.
986 - afs tracks audio file selection also in playlist mode.
987 - few easy-to-use afs commands replace the many not-so-easy-to-use
988 mysql commands (and are available also in playlist mode).
989 - Improved error subsystem.
990 - The earth-shaking new logo.
992 -----------------------------------------
993 0.2.17 (2007-11-20) "isotropic threshold"
994 -----------------------------------------
996 Mainly bugfixes and cleanups in this version which marks the end of
997 the 0.2.x series if no serious bugs show up after the release.
999 - mysql_selector: fix a locking bug.
1000 - universal chunk queueing.
1001 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
1003 - be more carful wrt. signed vs. unsigned argument passing.
1004 - cleanup error.h and fix some references to invalid error
1006 - update to gengetopt-2.21.
1007 - update to ortp-0.13.1.
1008 - autoconf: extend checks for headers, library functions and
1009 compiler characteristics.
1010 - Fix streaming of large mp3 files.
1011 - Fix an off-by-one bug in playlist handling.
1013 --------------------------------------
1014 0.2.16 (2007-04-05) "neural discharge"
1015 --------------------------------------
1017 The main change in this release is the major audio format handler
1018 cleanup which removes some similar/duplicate code and makes it easier
1019 to implement plugins for other audio formats. Of course, the usual mix
1020 of other improvements/changes/bugfixes also made it into the release.
1022 - simplified audio format handlers (most of the handling functions
1023 were moved one layer up to the virtual streaming system).
1024 - para_server uses mmap to read audio files
1025 - repositioning of mp3 streams is much faster, in particular for
1026 jumping near the end of large mp3 files.
1027 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
1029 - fix a bug in para_filter that caused decoding of aac files
1030 to start only after a few seconds.
1031 - fix osx_writer hangs
1032 - simplified dccp code (thanks to Gerrit Renker)
1033 - the compress filter works also on big endian systems (ppc)
1035 -----------------------------------------
1036 0.2.15 (2007-02-16) "inductive resonance"
1037 -----------------------------------------
1039 Minor improvements, more documentation and a bunch of bug fixes.
1041 - para_server: The server.users file is only read once on server
1042 startup rather than for each connection
1043 - mp3dec: Fix decoding of corrupt mp3 files
1044 - afs (audio file sender) is now called vss (virtual streaming
1045 system). Consequently, the permission flags specified in
1046 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
1047 become VSS_READ and VSS_WRITE respectively.
1048 - para_audiod/para_filter: Fix a bug that caused the last chunk
1049 of audio data not being written under certain circumstances
1050 - audiod: compute the difference of server time and local time
1052 - para_server/para_audiod: Fix some memory leaks
1053 - documentation improvements
1054 - configure.ac: fix checks for para_krell
1057 -------------------------------------------
1058 0.2.14 (2006-10-15) "transient singularity"
1059 -------------------------------------------
1061 The only major enhancement of this version is the osx writer which completes
1062 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
1063 until now for reasons beyond the scope of this changelog entry.
1065 - new output plugin for Mac Os: the osx writer
1066 - rename configure command line options from --enable-xxx-headers to
1067 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
1068 - configure: new command line options: --with-mad-headers,
1069 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
1070 - some robustness fixes
1071 - dymamic audio format recognition for audiod
1072 - para_server: new command line option: --autoplay_delay
1073 - para_audiod: new command line option: --clock_diff_count
1075 ---------------------------------------
1076 0.2.13 (2006-07-14) "sonic convolution"
1077 ---------------------------------------
1079 A bunch of new features and core changes.
1081 - the new paraslash scheduler, short and sweet.
1082 - Support for m4a/mp4 files via the new aac audio format
1083 handler/filter (requires libfaad).
1084 - each writer has its own command line parser, just like
1085 para_recv and para_filter.
1086 - para_client and para_audioc use the error subsystem
1087 - writers are integrated in para_audiod (currently linux-only)
1088 - para_client is integrated in para_audiod
1089 - random/playlist selector: improved info strings
1090 - new audiod commands: tasks, kill
1091 - update to libortp-0.10.1
1092 - para_fade: wake time defaults to 8 hours from now
1093 - update to autoconf-2.60
1095 ------------------------------------------
1096 0.2.12 (2006-05-12) "oriented abstraction"
1097 ------------------------------------------
1099 Many user-visible changes in this release and lots of new
1102 - the new optional dccp sender/receiver. It uses the datagram
1103 congestion control protocol. You'll need a fairly new kernel
1105 - paraslash works on Mac OS X (thanks to Gerd Becker)
1106 - para_play renamed to para_write
1107 - modular output plugin design (writers) for para_write
1108 - new file_writer output plugin for para_write
1109 - compress filter speed improvements
1110 - update to libortp-0.9.1
1111 - update to gengetopt-2.17rc
1112 - para_client no longer depends on libreadline (as the
1113 code for the interactive mode was removed).
1114 - gcc-2-95 is no longer a supported compiler. It may still
1115 work, but it gets no more testing.
1116 - the tarball no longer contains the screenshot images which
1117 reduces its size quite a bit.
1118 - configure: new command line options: --enable-mysql-headers
1119 and --enable-mysql-libs
1121 ------------------------------------
1122 0.2.11 (2006-03-11) "atomic duality"
1123 ------------------------------------
1125 Here it is, the first paraslash release developed with git. There
1126 are fairly many user-visible changes in this release. As two out of
1127 the three "database tools" of paraslash don't use a database at all,
1128 they are now called "audio file selectors" instead.
1130 - the cdt command (change database tool) becomes chs (change
1132 - no more colon separators: The syntax of some options of
1133 para_audiod and para_filter have changed. Use --help for
1134 more info (and some examples).
1135 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
1136 - switch from cvs to git (should've done that earlier)
1137 - the new ipc subsystem
1138 - new audio file selector: playlist
1139 - para_server: the dopey selector is now called "random",
1140 and is the default selector. Use the --selector option to
1141 choose another selector at startup, or the chs command to
1142 change the selector at runtime.
1143 - X86_64 fixes (thanks to Steffen Klassert)
1146 --------------------------------------
1147 0.2.10 (2006-02-17) "cyclic attractor"
1148 --------------------------------------
1150 Huge documentation update, a scrollable window for para_gui, ortp
1151 improvements, and of course many small fixes not mentioned here.
1152 The diffstat below is rather misleading as most insertions are due
1153 to the new source documentation.
1156 - para_server also uses the new error subsystem
1157 - lots of new documentation (UTSL)
1159 - keysyms for cursor keys and for next/previous page keys
1160 - scrollable output window
1161 - new internal commands: scroll up/down, page up/down
1162 - fix color of command output.
1163 - ortp: the --chunk_time and --header flags are no longer needed
1164 for para_recv/para_audiod as this information is now encoded in
1165 each rtp packet sent by para_server.
1167 -------------------------------------------
1168 0.2.9 (2006-01-24) "progressive turbulence"
1169 -------------------------------------------
1171 Internal audiod receivers/filters, the new error subsystem and
1172 a lot of small improvements.
1174 - para_recv and para_filter are integrated into the para_audiod
1175 binary, i.e. audiod no longer spawns a new process for
1176 each receiver/filter. As para_recv and para_filter might be
1177 useful as standalone programs, they still get built (linked
1178 against the same object files that are also used for audiod).
1179 - further ortp timing improvements should reduce the CPU usage
1180 of the ortp receiver.
1181 - improved audio grabbing. The 'grab' command of para_audiod
1182 has its own set of command line options. Read the output of
1183 "para_audioc help grab" for more info.
1184 - oggdec: configurable input prebuffer size.
1185 - the new error subsystem gives better error diagnostics
1186 and reduces code size.
1188 -----------------------------------------
1189 0.2.8 (2006-01-02) "dynamic accumulation"
1190 -----------------------------------------
1192 The new modular filter design and the para_play-hangs bugfix.
1194 - new executable: para_filter. It combines para_mp3dec,
1195 para_oggdec and para_compress. It also adds a further filter
1196 type, wav, that just inserts a wave header at the desired point
1197 of the filter chain. All 'piping' is done in-memory (i.e. no
1198 read/write operations are used).
1199 - para_play: fix a stupid bug that caused it to hang under
1200 certain circumstances.
1202 -------------------------------------------
1203 0.2.7 (2006-12-27) "transparent invariance"
1204 -------------------------------------------
1206 Not many user-visible changes but a fair amount of internal improvements.
1208 - The http sender buffers data if it can not be sent
1209 out immediately (because the socket is not writable). This
1210 should prevent para_server from shutting down the connection
1211 too early on a loaded network.
1212 - para_play also prebuffers data if it is told to start at a
1213 future time by the --start_time option.
1214 - The return of para_recv: It combines para_ortp_recv and
1215 para_http_recv. Use the --receiver option to switch between
1216 the two. para_recv builds without libortp, but contains
1217 only the http receiver in this case.
1218 - update to ortp 0.8.1. As this ortp release contains incompatible
1219 changes, para_recv-0.2.7 won't link against older ortp libs.
1220 - improved ortp timings.
1221 - use of gcc-extensions that #define away for non-gcc and
1224 -------------------------------------------
1225 0.2.6 (2005-10-29) "recursive compensation"
1226 -------------------------------------------
1228 Transparent session encryption (uses openssl's Alleged RC4 cipher),
1229 the internal find command and several other improvements and cleanups.
1231 - Encrypt the session if encryption is requested by the client
1232 (default for para_client 0.2.6). This is backwards
1233 compatible, so older clients can still connect to para_server
1234 0.2.6. Use the new client option --plain to request an
1235 uncrypted session (off by default, must be set to on in
1236 order to connect to para_server 0.2.x with 0 <= x <= 5).
1237 - para_server uses an internal function to locate audio files
1238 rather than calling find(1). The server option
1239 --mysql_audio_file_dir replaces --mysql_find_cmd.
1240 - documentation update
1242 - header file cleanup
1243 - para_client code cleanup
1244 - para_gui: faster display of output of display commands
1246 ------------------------------------------
1247 0.2.5 (2005-10-13) "aggressive resolution"
1248 ------------------------------------------
1250 This release adds internal senders, i.e. no more external programs are
1251 spawned for sending out the audio data. There are two different senders
1252 available: The http sender and the ortp sender (former para_send which
1253 is no longer needed).
1255 The new sender code has a plugin-like design so it can be easily
1256 extended should there be be any future need for supporting another
1257 network streaming protocol. All senders are completely independent of
1258 each other. In particular, the http and the ortp sender can operate
1261 - new server command: sender to control senders at runtime.
1262 Read the output of "para_server -h" and "para_client help
1263 sender" for more information.
1264 - para_recv renamed to para_ortp_recv
1265 - new executable: para_http_recv, a simple command line
1267 - major afs/mp3/ogg code simplifications due to internal
1269 - ogg timing improvements
1270 - fix several minor memory leaks (found by valgrind)
1271 - empty stream definitions work again
1272 - com_ne(): ignore errors on remove
1273 - audiod: fix segfault on server restart
1275 ---------------------------------------
1276 0.2.4 (2005-09-21) "toxic anticipation"
1277 ---------------------------------------
1279 Several small improvements, fixes and the new grab command.
1282 - new command: "grab" to grab the output of the stream reader
1283 or any filters. Read the output of "para_audioc help grab"
1284 for more information.
1287 - audioc: new command line option: --bufsize to specify a
1288 buffer size different from the default size 8192.
1289 - improved error diagnostics for para_play.
1290 - new configure option: --enable-ssldir so search for openssl in
1292 - sdl_gui: Make it look nice again for 1024x768
1293 - server: report total size of memory allocated with sbrk by malloc,
1294 new command line option: --announce_time
1296 -----------------------------------------
1297 0.2.3 (2005-09-01) "hydrophilic movement"
1298 -----------------------------------------
1300 Two new executables and major feature enhancements.
1302 - audiod filters: It is now possible to specify arbitrary many
1303 (including none) filters for each supported audio
1304 format. This can be used e.g. for normalizing volume,
1305 transforming or grabbing the audio stream, or for using
1306 visualizers. Read the output of "para_audiod -h" for the
1307 syntax of the new --filter_cmd option.
1308 - new executable: para_play, a tiny alsa player. It
1309 can play wave files or raw pcm (16 bit little endian)
1311 - new executable: para_compress, a dynamic range compressor
1312 intended to keep audio output at a consistent volume. Derived
1313 from [AudioCompress](http://trikuare.cx/code/AudioCompress.html).
1314 - audiod: New option: --stream_delay. This can be used in
1315 a local network to syncronize the audio output of all
1316 clients that play the same stream.
1318 ------------------------------------------
1319 0.2.2 (2005-08-19) "tangential excitation"
1320 ------------------------------------------
1322 Mostly internal changes in this release, but also some new commands
1323 for the mysql database tool.
1325 - cleanup exec.c, fix para_exec bug
1326 - compile time loglevel (log messages below the given level
1327 won't be compiled in, which reduces the size of the
1329 - new log macros that shorten the size of the source code.
1330 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
1331 to send only zeros. With this workaround, para_audioc works
1333 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
1334 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
1335 (new entry), "snp" (set numplayed). Read the manual for more
1338 ---------------------------------------
1339 0.2.1 (2005-08-15) "surreal experience"
1340 ---------------------------------------
1342 Here comes paraslash-0.2.1. It contains a couple of new features and,
1343 surprise, only minor bug fixes.
1345 - kill noisy mp3 debug message
1346 - cleanup of the build system
1347 - para_server and para_client directly use the crypto routines
1348 of the openssl library rather than invoking the openssl command
1350 - server/audiod: new option --user to switch to the given user
1351 when invoked as root. Read the output of "para_server -h" for
1353 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
1354 status. Default: "para_audioc stat"
1355 - sdl_gui: new option --pic_cmd to be used to download the picture.
1356 Default: "para_client pic"
1357 - audiod: 5 slots ought to be enough for everybody
1358 - audiod: new status item: Uptime, kill hup command
1360 ------------------------------------------
1361 0.2.0 (2005-08-06) "distributed diffusion"
1362 ------------------------------------------
1364 After several month of increased development activity, paraslash-0.2.0
1365 has arrived. It contains many new features and is much more
1366 self-contained than the old 0.1.x series. Enjoy!
1368 - para_server: fix hang on song change and crash on sighup.
1369 Speed up mysql queries. The DIR_LIKE macro is gone.
1370 - new executables: para_audiod, the local audio daemon that
1371 starts playback (uses SCM_CREDENTIALS socket magic) and
1372 para_audioc, the corresponding client.
1373 - new executables: para_mp3dec/para_oggdec, two really teensy
1374 decoders. para_mp3dec is based on libmad, para_oggdec requires
1376 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
1377 they are now called para_send and para_recv respectively.
1378 - documentation updates
1379 - para_gui is themable. For now there is the default theme that
1380 looks as before and the simple theme: blue and easy.
1381 - gui: audio streaming is now handled by audiod. Time display shows
1382 playback time rather than streaming time
1383 - slider: update to libzmw-0.2.0
1384 - para_krell: fix crash on server shutdown
1385 - switch from gzip to bzip2
1387 ----------------------------------------
1388 0.1.7 (2005-04-18) "melting penetration"
1389 ----------------------------------------
1391 The main change in this release is clearly the oggvorbis rewrite,
1392 but there are also lots of smaller changes. If you intend to use both
1393 the mp3 and the ogg plugin, it is recommended to use software mixing,
1394 e.g. the dmix plugin which is provided by ALSA.
1396 - new executables: para_ovsend and para_ovrecv for sending/receiving
1397 oggvorbis files via rtp. Requires the open rtp library. Get it at
1398 http://www.linphone.org/ortp/
1399 - rewrite of the ogg_vorbis core code
1400 - configure detects libzmw and, if detected, includes
1401 para_slider to the list of binaries to be built by make
1402 - server stream writers read from their associated fifo rather
1404 - slider: two new sliders, lastplayed and numplayed
1405 - fix nasty double free bug which caused random segfaults in case of
1406 mp3 files with invalid header information
1407 - gui: new command line option: --stream_timeout=seconds to
1408 deactivate a slot if it is idle for that many seconds (default=`5')
1411 ---------------------------------------
1412 0.1.6 (2005-03-05) "asymptotic balance"
1413 ---------------------------------------
1415 Only little user-visible changes in this release. Mainly bugfixes and
1416 core code cleanup. This is probably the most stable version ever if you
1419 - fix several memory leaks
1420 - rename default name of mysql database from "music" to "paraslash".
1421 Use para_server's --mysql_database option if you do not want to
1422 rename your old database.
1423 - rework ogg vorbis code
1424 - make update command work on mysql servers with LOCAL_INFILE
1426 - gui: improved stream I/O (slots)
1427 - simplified audio format API
1428 - para_pob_ogg is gone
1430 ------------------------------------
1431 0.1.5 (2004-12-31) "opaque eternity"
1432 ------------------------------------
1434 Let's slide gently into the new year.
1436 - new: para_slider (not built automatically, type "make
1437 para_slider" to build). A toy for those who always felt that
1438 creating stream definitions is difficult. See screenshots,
1439 README and FEATURES for more info.
1440 - improved signal handling. Fixes server segfault on SIGHUP
1441 for linux kernels newer than Aug 24 2004 and makes para_gui
1443 - reload database tool on SIGHUP
1444 - improved help message for sl
1445 - do not log "broken pipe" messages as errors. They are
1447 - fix wrong error message on permission errors
1449 -----------------------------------------
1450 0.1.4 (2004-12-19) "tunneling transition"
1451 -----------------------------------------
1453 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1454 Hopefully, most of them got wiped out with this release. Some
1455 enhancements went also in.
1457 - improved error diagnostics for all commands
1458 - stradd/picadd: overwrite previous contents if entry already
1459 exists, rather than returning errors
1460 - stradd: use current stream if invoked without args
1461 - faster (and hopefully more stable) ogg-vorbis handling
1462 - para_krell: reap children to avoid zombie-flooding in case
1463 no server is running
1464 - si: report also server pid
1465 - server: don't busy-loop if dbtool reports only invalid files.
1466 - gui: CTRL+C works again, fix stream_read command line option
1468 - fix mysql dbtool startup in case no database exists
1469 - many small fixes and cleanups
1471 ---------------------------------------
1472 0.1.3: (2004-12-10) "vanishing inertia"
1473 ---------------------------------------
1475 Starting from this release, the database tools are integrated in the
1476 server binary. This decreases server startup time, reduces code size
1477 and speeds up database commands. However, the layout of the underlying
1478 mysql database changed only slightly and 0.1.3 should be backwards
1479 compatible in that respect.
1483 - If mysql is not detected at compile time, or fails to init
1484 at runtime, fall back to the dopey database tool which should
1486 - para_dbtool and dbtool.conf are gone. All mysql specific
1487 options are read from server.conf and are prefixed by 'mysql_'.
1488 - new command: cdt (change database tool)
1489 - new command line option: dbtool (choose startup database tool)
1490 - The name of current stream is now stored in the database,
1491 so paraslash remembers its current stream when restarted.
1492 - new command: csp (change stream and play)
1493 - para_gui also reports current database tool and server uptime
1495 -------------------------------------------
1496 0.1.2: (2004-11-28) "spherical fluctuation"
1497 -------------------------------------------
1499 Point release before the big dbtool changes go in.
1501 - dbtool: rename ca to cam (copy all meta data). It now also
1502 copies numplayed and lastplayed time as well as the picture
1504 - fix endless-loop-bug caused by mp3 files with invalid header
1506 -----------------------------------------
1507 0.1.1: (2004-11-05) "floating atmosphere"
1508 -----------------------------------------
1511 - new dbtool command: mbox. Browse your sound-file collection
1512 with your favorite mail reader.
1513 - several small fixes
1515 -------------------------------------
1516 0.1.0: (2004-10-22) "rotating cortex"
1517 -------------------------------------
1519 - fix logging bug for loglevel > VERBOSE
1521 - correct timings for vbr mp3s
1522 - modular audio format support
1523 - ogg-vorbis support (experimental)
1524 - new server option: autoplay
1526 -----------------------------------------
1527 0.0.99: (2004-07-25) "harmonic deviation"
1528 -----------------------------------------
1530 - rename projectname from icc to paraslash (play, archive, rate
1531 and stream large audio sets happily)
1532 - paraslash is no longer restricted to one particular audio
1534 - new dbtool commands (stradd, strq, strdel) for easy stream
1535 managment w/o configuration file. That obsoletes stream_defs
1536 file/config option for dbtool.
1537 - picadd accepts jpeg data from stdin
1538 - new server commands: ps (select previous stream), sc (song change)
1539 - new default pictures for sdl_gui
1540 - gui: new key_map option for binding commands and internal
1541 functions to arbitrary keys, nice help screen, rip out
1542 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1543 show silly logo on startup
1544 - new executables: para_fade for fading volume, para_dbadm for
1545 manipulating attributes
1546 - cdb adds _all_ tables to mysql database
1547 - revised and beautified documentation
1548 - sample dbtool rewritten in C
1551 ---------------------------------------------
1552 0.0.98: (2003-12-26) "incremental smoothness"
1553 ---------------------------------------------
1555 - kick icecast in favour of poc. That removes some races and reduces
1556 core code considerably.
1557 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1558 give finer info on afs' status.
1559 - gui can start decoder (see config options). Further new gui
1560 commands: refresh (^L), jmp (F1-F10)
1561 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1562 terminates gui. This fixes dead instances consuming memory
1564 - new dbtool command: verb for sending verbatim sql queries.
1565 - fix pid_list races (by removing pid_list)
1568 --------------------
1569 0.0.97: (2003-10-26)
1570 --------------------
1572 - installation prefix now defaults to /usr/local
1573 - new commands for gui: snozze, sleep and reread config
1574 - config file for gui and sdl_gui
1575 - fix problems with filenames containing funny characters
1576 (reported by Thomas Forell)
1577 - improved signal handling for gui, now it rereads conf on SIGHUP
1578 - new dbtool command: cdb (create database)
1579 - switch from argtable to gengetopt
1580 - major code cleanup and speed improvements
1581 - fix several potential buffer overflows
1582 - many small fixes and cleanups
1588 - easy stream_defs syntax
1589 - sdl_gui can display images associated to the file being played
1590 - Major feature enhancements for icc_gui including dynamic text
1591 placement and the top/bottom window design
1592 - vrfy/clean now also checks for NULL values in attributes as
1593 well as for invalid picture pointers
1594 - fix long outstanding case sensitivity bug
1595 - many small fixes and cleanups
1601 - sdl gui runs much faster
1602 - new dbtool command: ca (copy attributes)
1603 - count and display number of times the song has been played
1604 - new feature: scoring
1605 - command line options for sdl_gui
1606 - simpler syntax of streams file
1607 - decrease network traffic of stat
1609 - many small fixes and cleanups
1615 - new server command: ns (next stream)
1616 - new icc_gui command: c (change stream)
1618 - stat shows also id3 tag info
1620 - log flodding bug fixed
1621 - many small fixes and cleanups
1627 - colors for icc_gui
1628 - icc_gui sets volume directly (linux only)

1631 with unsufficient permissions
1632 - new command: hup to make all servers reread their configuration file
1633 - icecast meta data streaming
1634 - many small fixes and cleanups
