4 ----------------------------------------------
5 0.5.1 (to be announced) "temporary implication"
6 ----------------------------------------------
8 - audiod improvements and fixes.
10 ----------------------------------------
11 0.5.0 (2013-08-23) "invertible validity"
12 ----------------------------------------
14 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
16 - The sideband compatibility code has been removed, hence
17 sideband connections (introduced in 0.4.11) are now mandatory.
18 - Addblob commands can produce output.
19 - The stat command no longer sends garbage when para_server was
20 compiled against libgcrypt.
21 - Dependencies for gengetopt files are computed automatically.
22 This eliminates a constant source of build bugs.
23 - The setatt command now accepts file name patterns rather than only
25 - overview.pdf is now based on dia, a simple diagram creation program.
26 The new version is much more detailed and contains descriptions of
27 the various programs of the paraslash package.
28 - The separator of all multi-word options has been changed from
29 underscore to dash. For example --log_color becomes --log-color.
30 - Overhauled web pages and the new logo.

35 --------------------------------------
36 0.4.13 (2013-07-29) "spectral gravity"
37 --------------------------------------
39 One more 0.4.x release before the API-breaking changes for 0.5.0 go
40 in. The main features of this release are the ogg/opus audio format,
41 and UTF-8 support, but it includes also tons of other improvements
42 and fixes all over the place.
44 - New audio format: ogg/opus.
45 - UTF8 support for para_gui and the mp3 audio format handler.
46 - Scheduler improvements and fixes.
47 - The obsolete gettimeofday() function has been replaced
48 by clock_gettime() on systems which support it.
49 - Speed and usability improvements for para_gui.
50 - para_client now restores the fd flags of stdin and stdout
52 - Improved manual pages.
53 - Consistent version strings for all executables.
54 - Reduced dependencies on generated files result in fewer
55 recompilations on changes.
56 - Performance improvements for the compress filter.
57 - Improved downloads web page.
59 -----------------------------------------
60 0.4.12 (2012-12-20) "volatile relativity"
61 -----------------------------------------
62 The new command line player, the resample filter, ALSA support for
63 para_fade, and the improved build system are the highlights of this
64 release which probably marks the end of the 0.4.x series.
66 - The afh receiver and the para_play executable.
67 - The resample filter: A sample rate converter based on
69 - The "versions" directory has been removed from the master
70 branch. The tarballs of the old releases are now available
71 in the new "releases" branch.
72 - Overhaul of the build system: All generated files are now
73 written to the "build" directory.
74 - The modular mixer API and the alsa mixer.
75 - Minor fixes for the osx writer.
77 --------------------------------------
78 0.4.11 (2012-07-20) "mutual diversity"
79 --------------------------------------
81 The major feature in this release is the new sideband API for
82 client-server communication. This API will be used exclusively starting
83 with 0.5.0, which breaks backward compatibility but allows to get rid
84 of quite some compatibility code. Other noteworthy changes include
85 decoder latency improvements and a long-standing bug fix for the
88 - Sideband connections: If both para_server and para_client
89 support this feature, data is sent as a multiplexed stream.
90 - The --no_default_filters option of para_filter has been
92 - Several fixes and latency improvements to various decoders.
93 - The ALSA writer now limits the prebuffer time to 500ms.
94 - Documentation improvements.
95 - Overhaul of the command_util.sh script.
96 - Fixes for some minor problems found by the clang analyzer.
97 - Compiles (almost) without warnings on gcc-3.
98 - Robustness improvements of the buffer tree code.
100 ------------------------------------------
101 0.4.10 (2012-03-30) "heterogeneous vacuum"
102 ------------------------------------------
104 Nothing earth-shaking in this release, but quite a few usability
105 improvements and the usual mix of cleanups and fixes.
107 - The --no_default_filters option of para_filter has been
108 deprecated. It still works but has no effect and will be
109 removed in the next version.
110 - para_gui now prints also the stderr output of the executing
111 command in the bottom window.
112 - Cleanup and consolidation of the various wrappers for
113 write(), writev(), send() and friends.
114 - The obscure error messages on mmap() failures have been
115 replaced by meaningful messages. This affects mainly
117 - para_audioc: Cleanups and memory leak fixes.
118 - Test 0004-server no longer fails if para_server is not
120 - New configure options: --with-id3tag-{headers,libs}.
122 -------------------------------------
123 0.4.9 (2011-12-06) "hybrid causality"
124 -------------------------------------
126 Support for another audio format, interactive mode for para_client
127 and para_audiod and many small improvements/fixes all over the place.
129 - Support for flac, the free lossless audio codec.
130 - Fix for an endless loop in the mp3 decoder for certain
132 - When executed without specifying a command, para_client
133 and para_audioc start an interactive shell (requires
134 libreadline being installed). The interactive mode offers
135 full tab completion and command line history.
136 - autogen.sh now detects a distcc setup and adjusts the
137 parameter for the -j option of make accordingly.
138 - Shared memory areas are no longer restricted to 64K. We now
139 detect the maximal size of a shared memory area at runtime.
140 - cleanup of the internal uptime API.
141 - para_server prefaults the mmapped audio file to avoid
142 delays on slow media.
143 - A new test for the test-suite that exercises the
144 communication between para_server and para_audiod.
145 - The alsa writer eats up less CPU cycles when configured to
147 - Simplified and unified receiver code.
149 - Commands which print a list of matching audio files now
150 emit a meaningful error message if no audio file matched the
153 --------------------------------------
154 0.4.8 (2011-08-19) "nested assignment"
155 --------------------------------------
157 Gcrypt support, the overhauled osx writer and regex format specifiers
158 are the highlights of this release.
160 - support for libgcrypt as a drop-in replacement for openssl.
161 Run configure --enable-cryptolib=gcrypt to link against
162 libgcrypt. The two crypto implementations are compatible to
163 each other, i.e. a para_client executable linked against
164 gcrypt can connect to para_server linked against libssl
166 - Rewrite of the osx writer (output plugin for Mac OS).
167 - audiod: The format specifier for receivers, filters and
168 writers is now treated as a regular expression. This allows
169 to replace 5 lines in the config file (one for each audio
170 format) by one single line. See the manual for details.
171 - The *.cmdline.[ch] files are no longer contained in the released
172 tarballs. This reduces the size of the tarballs but requires
173 gengetopt to build the tarball.
174 - Compiles cleanly also with llvm/clang.
175 - Corrupt mp3 files are handled more gracefully.
176 - The alsa writer uses poll fds instead of computing timeouts.
177 - Cleanup of the generic writer API.
178 - sched: Optimized zero timeouts.
179 - vss timeout cleanups.
180 - oggdec fixes and improvements.
182 --------------------------------------
183 0.4.7 (2011-06-01) "infinite rollback"
184 --------------------------------------
186 The new ao writer, support for ssh RSA keys and a couple of other
189 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
190 platforms through the libao audio library.
191 - Support for RSA keys generated with ssh-keygen.
192 - configure: improved options for ogg/vorbis/speex.
193 - The git version reported by --version always matches HEAD.
194 - The autogen script detects the number of processors and
195 runs a parallel make if possible.
196 - Major cleanup of the crypto API.
197 - Documentation updates.
199 ------------------------------------------
200 0.4.6 (2011-03-31) "deterministic entropy"
201 ------------------------------------------
203 Lots of ogg/vorbis improvements, the new test suite, enhancements
204 for para_gui and a fair amount of other bug fixes.
206 - For DCCP/OGG streams the audio file header is only sent once
207 at the beginning of the stream rather than periodically
208 every five seconds. This reduces network traffic and the
210 - The vorbis comment header is replaced by an empty dummy header
211 before the header is sent over the network. This also results in
212 less network traffic and smaller FEC groups.
213 - The new "test" make target allows to perform some sanity checks prior
214 to installing the package.
215 - ogg timing fixes and performance improvements
216 - Scheduler improvements
217 - Proper exit codes for para_write
218 - para_gui: New option --theme to select a startup theme. Several
219 other improvements and fixes.
220 - aacdec error message cleanups
221 - simplified color error handling
223 --------------------------------------------
224 0.4.5 (2010-12-17) "symmetric randomization"
225 --------------------------------------------
227 Bug fixes, internal cleanups and variable-sized FEC slices.
229 - Contains a fix for an invalid-free-bug in the ogg audio format
231 - Switching off the DCCP sender works again.
232 - para_audiod handles crashes of para_server more robustly.
233 - Internal scheduler and writer cleanups.
234 - Reduced latency due to variable-sized FEC slices.
235 - Improved documentation and error diagnostics.
236 - The build of para_server is now optional, allowing the build
237 to succeed in case libosl is not installed.
239 ------------------------------------------
240 0.4.4 (2010-08-06) "persistent regularity"
241 ------------------------------------------
243 Support for yet another audio format, para_write improvements and
246 - Support for the speex codec.
247 - Support for sample formats other than 16 bit little endian.
248 - error2.h is now created by a perl script which speeds up configure
250 - Fix a bug in the aac decoder which could lead to segfaults in
251 para_filter/para_audiod.
252 - Fixes for autoconf-2.66.
254 ----------------------------------------
255 0.4.3 (2010-07-05) "imaginary radiation"
256 ----------------------------------------
258 Many improvements for the DCCP and the UDP transport, the new user
259 manual and the usual mix of bug fixes and internal improvements.
261 - FEC support for the DCCP sender (Gerrit Renker). The new
262 --dccp_max_slice_size, --dccp_data_slices_per_group and
263 --dccp_slices_per_group options can be used to set the FEC
264 parameters for the DCCP transport.
265 - DNS lookups for UDP targets (Gerrit Renker).
266 - The new user manual replaces the README, README.afs, REQUIREMENTS
267 and INSTALL documents.
268 - Fix an end-of-file detection bug in the oggdec filter.
269 - The new nonblock API.
270 - Both options of the oggdec filter have been removed.
271 - New debug mode for the internal scheduler.
273 ------------------------------------------
274 0.4.2 (2010-04-23) "associative expansion"
275 ------------------------------------------
277 It's been some time since the last release, but finally here is
278 paraslash-0.4.2. The bulk of the changes comes from the new buffer
279 tree API, but there are changes all over the tree. Mainly performance
280 and usability improvements, but also quite some bug fixes.
282 - The new buffer tree API.
283 - DCCP: Support for CCID negotiation (Gerrit Renker).
284 - UDP robustness fixes.
285 - The --bufsize option for mp3dec is gone as it no longer makes sense
286 for the new buffer tree API.
287 - Fix audible buffer underruns for wma streams.
288 - The alsa writer no longer prints meaningless underrun durations.
289 - audiod: Defaults work also for udp streams. If no filter is
290 given for an audio format that is received via upd, fecdec is
291 automatically added as the first filter (along with the decoder).
293 ---------------------------------------
294 0.4.1 (2009-12-22) "concurrent horizon"
295 ---------------------------------------
297 Support for another audio format, minor feature enhancements and lots of bug
298 fixes. All fixes that have been accumulated in the maint branch (in particular
299 those mentionened in the 0.3.6 release notes) appear in this release as well.
302 - new afh option: --human to activate human-readable output.
303 - new server/audiod option: --log-timing to print timing information.
304 - build system improvements.
305 - source code documentation updates.
307 -------------------------------------
308 0.3.6 (2009-12-07) "cubic continuity"
309 -------------------------------------
311 Quite a few bugs have been found and fixed since 0.3.5, so here's
312 another 0.3.x release. No new features.
314 - Always check return value of malloc().
315 - ogg vorbis/FEC: Do not write garbage after the audio file header.
316 - exit if root privileges could not be dropped.
317 - FEC: Fix computation of extra slices.
318 - oss: Fix check for empty input buffer.
319 - Avoid buffer underruns due to filter chain output buffer constraints.
320 - server: Fix assignment of afs_pid.
321 - Don't panic if the afs database contains unknown audio formats.
322 - http/dccp: Do not send the audio file header twice.
323 - FEC: Timing improvements.
325 ----------------------------------------------
326 0.4.0 (2009-11-10) "simultaneous independence"
327 ----------------------------------------------
329 Two significant changes which require the new version number: The
330 improved authentication dialog and the fact that the database code
331 has been moved to a library, libosl. To use the new version, you have
332 to generate new RSA keys, see INSTALL for details. A shell script is
333 provided for conversion of the 0.3 database to the new 0.4 format.
335 - stronger crypto for client authentication
336 - the database code has been moved to a library
337 - improved status item handling
338 - cleanup of the build system
339 - The "-V" option now also prints the git version
340 - the new parser-friendly listing mode for the ls and stat commands
341 - mandatory rc4 encryption
342 - major audio format handler cleanups
343 - (id3,...) tags are no longer stored as a combined string in the database
344 - new mood methods: artist_matches, title_matches, comment_matches,
345 album_matches, year_maches, year.
347 --------------------------------------------
348 0.3.5 (2009-09-21) "symplectic separability"
349 --------------------------------------------
351 Full client support for *BSD Unixes, complete re-write of the ogg
352 vorbis audio format handler, various improvements all over the place
353 and the usual mix of bugfixes. This release marks the end of the 0.3
354 series if no serious problems show up.
356 - the new oss writer (supported on *BSD and Linux)
357 - rewrite of the ogg vorbis audio format handler. It's
358 recommended to replace the chunk tables of existing ogg
359 vorbis files in the afs database by re-adding these files
361 - support for netmask subsets (Gerrit Renker)
362 - the new prebuffer filter
363 - improved signal handling
364 - variable fec output buffer size
365 - improved FEC timing fixes audible buffer underruns in UDP mode
366 - --log_color actually works
367 - new ls option: -d (print dates as seconds after the epoch)
368 - update to gengetopt 2.22.2
369 - support for RSA keys of size > 512 bits
370 - new option "mixer_channel" for para_fade
372 -----------------------------------------
373 0.3.4 (2009-05-07) "elliptic inheritance"
374 -----------------------------------------
376 The new udp sender, forward error correction, colored logs and various
377 other improvements. As the udp sender does not depend on any special
378 libraries, it is built unconditionally.
380 - The udp sender replaces the ortp sender. The new code uses forward
381 error correction to protect against packet losses. Many thanks to
382 Gerrit Renker for providing ipv6 support.
383 - The default port for udp streaming now defaults to 8000, like
384 for the http and the dccp senders/receivers.
385 - Loglevels are now specified as symbolic names, e.g.
387 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
388 - para_server/para_audiod: Color support for log messages.
389 - new options for mp3dec: --ignore-crc, --bufsize
390 - new audiod option: --config-file.
391 - gengetopt cleanups.
392 - Improved help/man pages: The documentation of para_audiod,
393 para_recv, para_filter and para_write now also contains
394 all options of the available receivers/filters/writers. The
395 man page of para_fade contains a description of the different
397 - More source code documentation.
400 --------------------------------------------
401 0.3.3 (2008-12-01) "axiomatic perspectivity"
402 --------------------------------------------
404 Internal code cleanups, bug fixes, improved tag handling and the new
405 amplification filter.
407 - para_server uses the generic scheduling code.
408 - overhaul of the virtual streaming system.
409 - mp3: id3 version 2 support via libid3tag (optional)
410 - ogg: vorbis comment support.
411 - aac meta info support.
412 - mp3 audio format handler cleanups.
413 - new filter: "amp" to amplify the amplitude of the audio stream
414 - new status item/database entry: amplification. It is
415 used by the amp filter to pre-amplify the audio stream.
416 - fix a close-without-open bug in para_write.
417 - fix a bug in com_init() which was introduced in 0.3.2.
418 - better error diagnostics for para_client.
420 -----------------------------------------
421 0.3.2 (2008-04-11) "probabilistic parity"
422 -----------------------------------------
424 The new para_afh executable, scheduling and documentation improvements.
426 - new ls option: -lc (list chunk table)
427 - new executable: para_afh, the stand-alone audio file handler tool
428 - afs commands can send output more than SHMMAX (32MB on Linux). This
429 also reduces the memory usage of commands that produce large amounts
431 - major scheduler and audiod cleanups.
432 - more detailed and much nicer man pages.
434 ---------------------------------------
435 0.3.1 (2008-02-23) "liquid interaction"
436 ---------------------------------------
438 A mix of cleanups, bug fixes, improvements, and some new features. No
439 significant changes to the new database (osl) code, which is generally
442 - Share some similar/duplicate code between the http and the
444 - Generic access control lists for paraslash senders.
445 - dccp sender: Access control lists, connection limiting and support
446 for the allow,deny,on,off,help sender commands.
447 - The default dccp port changed from 5001 to 8000 (suggested by
449 - para_server starts even if not all public keys could be loaded.
450 - Audiod performance improvements.
451 - fix a bug in the "off" command of the http sender.
452 - fix some fd and memory leaks.
453 - Update to gengetopt-2.22.
455 -------------------------------------
456 0.3.0 (2008-01-12) "solar saturation"
457 -------------------------------------
459 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
462 Usually one might expect lots of new features AND a big increase in size
463 for a major release like this.
465 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
466 ever. The decrease in size is mostly due to the removal of some
467 graphical tools (which were only quick hacks anyway). But also the
468 fact that the mysql code is gone cuts down the size a bit.
470 Being independent of mysql comes at a cost: The fact that paraslash
471 now contains its own database (the object storage layer, osl) increases
472 the (stripped) binary size of para_server by ~50K on i386.
474 - no more restrictions on unique basenames.
475 - independent of mysql: The new self-contained object
476 storage layer (osl) replaces the mysql database.
477 - New executable para_fsck: Check integrity of osl tables.
479 - Reliable audio file move/rename detection.
480 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
481 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
483 - the new osl-based audio file selector (afs) replaces the random,
484 the playlist and the mysql selector of paraslash-0.2.x.
485 - IPv6 support (thanks to Gerrit Renker).
486 - paraslash-0.2.x streams are now called "moods". Writing
487 0.3.x-mood definitions should be both easier and more
488 powerful than writing 0.2.x-stream definitions.
489 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
490 been removed. The world is a better place without them. However,
491 para_gui is still there.
492 - afs tracks audio file selection also in playlist mode.
493 - few easy-to-use afs commands replace the many not-so-easy-to-use
494 mysql commands (and are available also in playlist mode).
495 - Improved error subsystem.
496 - The earth-shaking new logo.
498 -----------------------------------------
499 0.2.17 (2007-11-20) "isotropic threshold"
500 -----------------------------------------
502 Mainly bugfixes and cleanups in this version which marks the end of
503 the 0.2.x series if no serious bugs show up after the release.
505 - mysql_selector: fix a locking bug.
506 - universal chunk queueing.
507 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
509 - be more carful wrt. signed vs. unsigned argument passing.
510 - cleanup error.h and fix some references to invalid error
512 - update to gengetopt-2.21.
513 - update to ortp-0.13.1.
514 - autoconf: extend checks for headers, library functions and
515 compiler characteristics.
516 - Fix streaming of large mp3 files.
517 - Fix an off-by-one bug in playlist handling.
519 --------------------------------------
520 0.2.16 (2007-04-05) "neural discharge"
521 --------------------------------------
523 The main change in this release is the major audio format handler
524 cleanup which removes some similar/duplicate code and makes it easier
525 to implement plugins for other audio formats. Of course, the usual mix
526 of other improvements/changes/bugfixes also made it into the release.
528 - simplified audio format handlers (most of the handling functions
529 were moved one layer up to the virtual streaming system).
530 - para_server uses mmap to read audio files
531 - repositioning of mp3 streams is much faster, in particular for
532 jumping near the end of large mp3 files.
533 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
535 - fix a bug in para_filter that caused decoding of aac files
536 to start only after a few seconds.
537 - fix osx_writer hangs
538 - simplified dccp code (thanks to Gerrit Renker)
539 - the compress filter works also on big endian systems (ppc)
541 -----------------------------------------
542 0.2.15 (2007-02-16) "inductive resonance"
543 -----------------------------------------
545 Minor improvements, more documentation and a bunch of bug fixes.
547 - para_server: The server.users file is only read once on server
548 startup rather than for each connection
549 - mp3dec: Fix decoding of corrupt mp3 files
550 - afs (audio file sender) is now called vss (virtual streaming
551 system). Consequently, the permission flags specified in
552 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
553 become VSS_READ and VSS_WRITE respectively.
554 - para_audiod/para_filter: Fix a bug that caused the last chunk
555 of audio data not being written under certain circumstances
556 - audiod: compute the difference of server time and local time
558 - para_server/para_audiod: Fix some memory leaks
559 - documentation improvements
560 - configure.ac: fix checks for para_krell
563 -------------------------------------------
564 0.2.14 (2006-10-15) "transient singularity"
565 -------------------------------------------
567 The only major enhancement of this version is the osx writer which completes
568 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
569 until now for reasons beyond the scope of this changelog entry.
571 - new output plugin for Mac Os: the osx writer
572 - rename configure command line options from --enable-xxx-headers to
573 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
574 - configure: new command line options: --with-mad-headers,
575 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
576 - some robustness fixes
577 - dymamic audio format recognition for audiod
578 - para_server: new command line option: --autoplay_delay
579 - para_audiod: new command line option: --clock_diff_count
581 ---------------------------------------
582 0.2.13 (2006-07-14) "sonic convolution"
583 ---------------------------------------
585 A bunch of new features and core changes.
587 - the new paraslash scheduler, short and sweet.
588 - Support for m4a/mp4 files via the new aac audio format
589 handler/filter (requires libfaad).
590 - each writer has its own command line parser, just like
591 para_recv and para_filter.
592 - para_client and para_audioc use the error subsystem
593 - writers are integrated in para_audiod (currently linux-only)
594 - para_client is integrated in para_audiod
595 - random/playlist selector: improved info strings
596 - new audiod commands: tasks, kill
597 - update to libortp-0.10.1
598 - para_fade: wake time defaults to 8 hours from now
599 - update to autoconf-2.60
601 ------------------------------------------
602 0.2.12 (2006-05-12) "oriented abstraction"
603 ------------------------------------------
605 Many user-visible changes in this release and lots of new
609 - the new optional dccp sender/receiver. It uses the datagram
610 congestion control protocol. You'll need a fairly new kernel
612 - paraslash works on Mac OS X (thanks to Gerd Becker)
613 - para_play renamed to para_write
614 - modular output plugin design (writers) for para_write
615 - new file_writer output plugin for para_write
616 - compress filter speed improvements
617 - update to libortp-0.9.1
618 - update to gengetopt-2.17rc
619 - para_client no longer depends on libreadline (as the
620 code for the interactive mode was removed).
621 - gcc-2-95 is no longer a supported compiler. It may still
622 work, but it gets no more testing.
623 - the tarball no longer contains the screenshot images which
624 reduces its size quite a bit.
625 - configure: new command line options: --enable-mysql-headers
626 and --enable-mysql-libs
628 ------------------------------------
629 0.2.11 (2006-03-11) "atomic duality"
630 ------------------------------------
632 Here it is, the first paraslash release developed with git. There
633 are fairly many user-visible changes in this release. As two out of
634 the three "database tools" of paraslash don't use a database at all,
635 they are now called "audio file selectors" instead.
638 - the cdt command (change database tool) becomes chs (change
640 - no more colon separators: The syntax of some options of
641 para_audiod and para_filter have changed. Use --help for
642 more info (and some examples).
643 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
644 - switch from cvs to git (should've done that earlier)
645 - the new ipc subsystem
646 - new audio file selector: playlist
647 - para_server: the dopey selector is now called "random",
648 and is the default selector. Use the --selector option to
649 choose another selector at startup, or the chs command to
650 change the selector at runtime.
651 - X86_64 fixes (thanks to Steffen Klassert)
654 --------------------------------------
655 0.2.10 (2006-02-17) "cyclic attractor"
656 --------------------------------------
658 Huge documentation update, a scrollable window for para_gui, ortp
659 improvements, and of course many small fixes not mentioned here.
660 The diffstat below is rather misleading as most insertions are due
661 to the new source documentation.
664 - para_server also uses the new error subsystem
665 - lots of new documentation (UTSL)
667 - keysyms for cursor keys and for next/previous page keys
668 - scrollable output window
669 - new internal commands: scroll up/down, page up/down
670 - fix color of command output.
671 - ortp: the --chunk_time and --header flags are no longer needed
672 for para_recv/para_audiod as this information is now encoded in
673 each rtp packet sent by para_server.
675 -------------------------------------------
676 0.2.9 (2006-01-24) "progressive turbulence"
677 -------------------------------------------
679 Internal audiod receivers/filters, the new error subsystem and
680 a lot of small improvements.
682 - para_recv and para_filter are integrated into the para_audiod
683 binary, i.e. audiod no longer spawns a new process for
684 each receiver/filter. As para_recv and para_filter might be
685 useful as standalone programs, they still get built (linked
686 against the same object files that are also used for audiod).
687 - further ortp timing improvements should reduce the CPU usage
688 of the ortp receiver.
689 - improved audio grabbing. The 'grab' command of para_audiod
690 has its own set of command line options. Read the output of
691 "para_audioc help grab" for more info.
692 - oggdec: configurable input prebuffer size.
693 - the new error subsystem gives better error diagnostics
694 and reduces code size.
696 -----------------------------------------
697 0.2.8 (2006-01-02) "dynamic accumulation"
698 -----------------------------------------
700 The new modular filter design and the para_play-hangs bugfix.
702 - new executable: para_filter. It combines para_mp3dec,
703 para_oggdec and para_compress. It also adds a further filter
704 type, wav, that just inserts a wave header at the desired point
705 of the filter chain. All 'piping' is done in-memory (i.e. no
706 read/write operations are used).
707 - para_play: fix a stupid bug that caused it to hang under
708 certain circumstances.
710 -------------------------------------------
711 0.2.7 (2006-12-27) "transparent invariance"
712 -------------------------------------------
714 Not many user-visible changes but a fair amount of internal improvements.
717 - The http sender buffers data if it can not be sent
718 out immediately (because the socket is not writable). This
719 should prevent para_server from shutting down the connection
720 too early on a loaded network.
721 - para_play also prebuffers data if it is told to start at a
722 future time by the --start_time option.
723 - The return of para_recv: It combines para_ortp_recv and
724 para_http_recv. Use the --receiver option to switch between
725 the two. para_recv builds without libortp, but contains
726 only the http receiver in this case.
727 - update to ortp 0.8.1. As this ortp release contains incompatible
728 changes, para_recv-0.2.7 won't link against older ortp libs.
729 - improved ortp timings.
730 - use of gcc-extensions that #define away for non-gcc and
733 -------------------------------------------
734 0.2.6 (2005-10-29) "recursive compensation"
735 -------------------------------------------
737 Transparent session encryption (uses openssl's Alleged RC4 cipher),
738 the internal find command and several other improvements and cleanups.
740 - Encrypt the session if encryption is requested by the client
741 (default for para_client 0.2.6). This is backwards
742 compatible, so older clients can still connect to para_server
743 0.2.6. Use the new client option --plain to request an
744 uncrypted session (off by default, must be set to on in
745 order to connect to para_server 0.2.x with 0 <= x <= 5).
746 - para_server uses an internal function to locate audio files
747 rather than calling find(1). The server option
748 --mysql_audio_file_dir replaces --mysql_find_cmd.
749 - documentation update
751 - header file cleanup
752 - para_client code cleanup
753 - para_gui: faster display of output of display commands
755 ------------------------------------------
756 0.2.5 (2005-10-13) "aggressive resolution"
757 ------------------------------------------
759 This release adds internal senders, i.e. no more external programs are
760 spawned for sending out the audio data. There are two different senders
761 available: The http sender and the ortp sender (former para_send which
762 is no longer needed).
764 The new sender code has a plugin-like design so it can be easily
765 extended should there be be any future need for supporting another
766 network streaming protocol. All senders are completely independent of
767 each other. In particular, the http and the ortp sender can operate
770 - new server command: sender to control senders at runtime.
771 Read the output of "para_server -h" and "para_client help
772 sender" for more information.
773 - para_recv renamed to para_ortp_recv
774 - new executable: para_http_recv, a simple command line
776 - major afs/mp3/ogg code simplifications due to internal
778 - ogg timing improvements
779 - fix several minor memory leaks (found by valgrind)
780 - empty stream definitions work again
781 - com_ne(): ignore errors on remove
782 - audiod: fix segfault on server restart
784 ---------------------------------------
785 0.2.4 (2005-09-21) "toxic anticipation"
786 ---------------------------------------
788 Several small improvements, fixes and the new grab command.
791 - new command: "grab" to grab the output of the stream reader
792 or any filters. Read the output of "para_audioc help grab"
793 for more information.
796 - audioc: new command line option: --bufsize to specify a
797 buffer size different from the default size 8192.
798 - improved error diagnostics for para_play.
799 - new configure option: --enable-ssldir so search for openssl in
801 - sdl_gui: Make it look nice again for 1024x768
802 - server: report total size of memory allocated with sbrk by malloc,
803 new command line option: --announce_time
805 -----------------------------------------
806 0.2.3 (2005-09-01) "hydrophilic movement"
807 -----------------------------------------
809 Two new executables and major feature enhancements.
811 - audiod filters: It is now possible to specify arbitrary many
812 (including none) filters for each supported audio
813 format. This can be used e.g. for normalizing volume,
814 transforming or grabbing the audio stream, or for using
815 visualizers. Read the output of "para_audiod -h" for the
816 syntax of the new --filter_cmd option.
817 - new executable: para_play, a tiny alsa player. It
818 can play wave files or raw pcm (16 bit little endian)
820 - new executable: para_compress, a dynamic range compressor
821 intended to keep audio output at a consistent volume. Derived
822 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
823 - audiod: New option: --stream_delay. This can be used in
824 a local network to syncronize the audio output of all
825 clients that play the same stream.
827 ------------------------------------------
828 0.2.2 (2005-08-19) "tangential excitation"
829 ------------------------------------------
831 Mostly internal changes in this release, but also some new commands
832 for the mysql database tool.
834 - cleanup exec.c, fix para_exec bug
835 - compile time loglevel (log messages below the given level
836 won't be compiled in, which reduces the size of the
838 - new log macros that shorten the size of the source code.
839 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
840 to send only zeros. With this workaround, para_audioc works
842 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
843 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
844 (new entry), "snp" (set numplayed). Read the manual for more
847 ---------------------------------------
848 0.2.1 (2005-08-15) "surreal experience"
849 ---------------------------------------
851 Here comes paraslash-0.2.1. It contains a couple of new features and,
852 surprise, only minor bug fixes.
854 - kill noisy mp3 debug message
855 - cleanup of the build system
856 - para_server and para_client directly use the crypto routines
857 of the openssl library rather than invoking the openssl command
859 - server/audiod: new option --user to switch to the given user
860 when invoked as root. Read the output of "para_server -h" for
862 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
863 status. Default: "para_audioc stat"
864 - sdl_gui: new option --pic_cmd to be used to download the picture.
865 Default: "para_client pic"
866 - audiod: 5 slots ought to be enough for everybody
867 - audiod: new status item: Uptime, kill hup command
869 ------------------------------------------
870 0.2.0 (2005-08-06) "distributed diffusion"
871 ------------------------------------------
873 After several month of increased development activity, paraslash-0.2.0
874 has arrived. It contains many new features and is much more
875 self-contained than the old 0.1.x series. Enjoy!
878 - para_server: fix hang on song change and crash on sighup.
879 Speed up mysql queries. The DIR_LIKE macro is gone.
880 - new executables: para_audiod, the local audio daemon that
881 starts playback (uses SCM_CREDENTIALS socket magic) and
882 para_audioc, the corresponding client.
883 - new executables: para_mp3dec/para_oggdec, two really teensy
884 decoders. para_mp3dec is based on libmad, para_oggdec requires
886 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
887 they are now called para_send and para_recv respectively.
888 - documentation updates
889 - para_gui is themable. For now there is the default theme that
890 looks as before and the simple theme: blue and easy.
891 - gui: audio streaming is now handled by audiod. Time display shows
892 playback time rather than streaming time
893 - slider: update to libzmw-0.2.0
894 - para_krell: fix crash on server shutdown
895 - switch from gzip to bzip2
897 ----------------------------------------
898 0.1.7 (2005-04-18) "melting penetration"
899 ----------------------------------------
901 The main change in this release is clearly the oggvorbis rewrite,
902 but there are also lots of smaller changes. If you intend to use both
903 the mp3 and the ogg plugin, it is recommended to use software mixing,
904 e.g. the dmix plugin which is provided by ALSA.
906 - new executables: para_ovsend and para_ovrecv for sending/receiving
907 oggvorbis files via rtp. Requires the open rtp library. Get it at
908 http://www.linphone.org/ortp/
909 - rewrite of the ogg_vorbis core code
910 - configure detects libzmw and, if detected, includes
911 para_slider to the list of binaries to be built by make
912 - server stream writers read from their associated fifo rather
914 - slider: two new sliders, lastplayed and numplayed
915 - fix nasty double free bug which caused random segfaults in case of
916 mp3 files with invalid header information
917 - gui: new command line option: --stream_timeout=seconds to
918 deactivate a slot if it is idle for that many seconds (default=`5')
921 ---------------------------------------
922 0.1.6 (2005-03-05) "asymptotic balance"
923 ---------------------------------------
925 Only little user-visible changes in this release. Mainly bugfixes and
926 core code cleanup. This is probably the most stable version ever if you
929 - fix several memory leaks
930 - rename default name of mysql database from "music" to "paraslash".
931 Use para_server's --mysql_database option if you do not want to
932 rename your old database.
933 - rework ogg vorbis code
934 - make update command work on mysql servers with LOCAL_INFILE
936 - gui: improved stream I/O (slots)
937 - simplified audio format API
938 - para_pob_ogg is gone
940 ------------------------------------
941 0.1.5 (2004-12-31) "opaque eternity"
942 ------------------------------------
944 Let's slide gently into the new year.
946 - new: para_slider (not built automatically, type "make
947 para_slider" to build). A toy for those who always felt that
948 creating stream definitions is difficult. See screenshots,
949 README and FEATURES for more info.
950 - improved signal handling. Fixes server segfault on SIGHUP
951 for linux kernels newer than Aug 24 2004 and makes para_gui
953 - reload database tool on SIGHUP
954 - improved help message for sl
955 - do not log "broken pipe" messages as errors. They are
957 - fix wrong error message on permission errors
959 -----------------------------------------
960 0.1.4 (2004-12-19) "tunneling transition"
961 -----------------------------------------
963 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
964 Hopefully, most of them got wiped out with this release. Some
965 enhancements went also in.
967 - improved error diagnostics for all commands
968 - stradd/picadd: overwrite previous contents if entry already
969 exists, rather than returning errors
970 - stradd: use current stream if invoked without args
971 - faster (and hopefully more stable) ogg-vorbis handling
972 - para_krell: reap children to avoid zombie-flooding in case
974 - si: report also server pid
975 - server: don't busy-loop if dbtool reports only invalid files.
976 - gui: CTRL+C works again, fix stream_read command line option
978 - fix mysql dbtool startup in case no database exists
979 - many small fixes and cleanups
981 ---------------------------------------
982 0.1.3: (2004-12-10) "vanishing inertia"
983 ---------------------------------------
985 Starting from this release, the database tools are integrated in the
986 server binary. This decreases server startup time, reduces code size
987 and speeds up database commands. However, the layout of the underlying
988 mysql database changed only slightly and 0.1.3 should be backwards
989 compatible in that respect.
993 - If mysql is not detected at compile time, or fails to init
994 at runtime, fall back to the dopey database tool which should
996 - para_dbtool and dbtool.conf are gone. All mysql specific
997 options are read from server.conf and are prefixed by 'mysql_'.
998 - new command: cdt (change database tool)
999 - new command line option: dbtool (choose startup database tool)
1000 - The name of current stream is now stored in the database,
1001 so paraslash remembers its current stream when restarted.
1002 - new command: csp (change stream and play)
1003 - para_gui also reports current database tool and server uptime
1005 -------------------------------------------
1006 0.1.2: (2004-11-28) "spherical fluctuation"
1007 -------------------------------------------
1009 Point release before the big dbtool changes go in.
1011 - dbtool: rename ca to cam (copy all meta data). It now also
1012 copies numplayed and lastplayed time as well as the picture
1014 - fix endless-loop-bug caused by mp3 files with invalid header
1016 -----------------------------------------
1017 0.1.1: (2004-11-05) "floating atmosphere"
1018 -----------------------------------------
1021 - new dbtool command: mbox. Browse your sound-file collection
1022 with your favorite mail reader.
1023 - several small fixes
1025 -------------------------------------
1026 0.1.0: (2004-10-22) "rotating cortex"
1027 -------------------------------------
1029 - fix logging bug for loglevel > VERBOSE
1031 - correct timings for vbr mp3s
1032 - modular audio format support
1033 - ogg-vorbis support (experimental)
1034 - new server option: autoplay
1036 -----------------------------------------
1037 0.0.99: (2004-07-25) "harmonic deviation"
1038 -----------------------------------------
1040 - rename projectname from icc to paraslash (play, archive, rate
1041 and stream large audio sets happily)
1042 - paraslash is no longer restricted to one particular audio
1044 - new dbtool commands (stradd, strq, strdel) for easy stream
1045 managment w/o configuration file. That obsoletes stream_defs
1046 file/config option for dbtool.
1047 - picadd accepts jpeg data from stdin
1048 - new server commands: ps (select previous stream), sc (song change)
1049 - new default pictures for sdl_gui
1050 - gui: new key_map option for binding commands and internal
1051 functions to arbitrary keys, nice help screen, rip out
1052 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1053 show silly logo on startup
1054 - new executables: para_fade for fading volume, para_dbadm for
1055 manipulating attributes
1056 - cdb adds _all_ tables to mysql database
1057 - revised and beautified documentation
1058 - sample dbtool rewritten in C
1061 ---------------------------------------------
1062 0.0.98: (2003-12-26) "incremental smoothness"
1063 ---------------------------------------------
1065 - kick icecast in favour of poc. That removes some races and reduces
1066 core code considerably.
1067 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1068 give finer info on afs' status.
1069 - gui can start decoder (see config options). Further new gui
1070 commands: refresh (^L), jmp (F1-F10)
1071 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1072 terminates gui. This fixes dead instances consuming memory
1074 - new dbtool command: verb for sending verbatim sql queries.
1075 - fix pid_list races (by removing pid_list)
1078 --------------------
1079 0.0.97: (2003-10-26)
1080 --------------------
1082 - installation prefix now defaults to /usr/local
1083 - new commands for gui: snozze, sleep and reread config
1084 - config file for gui and sdl_gui
1085 - fix problems with filenames containing funny characters
1086 (reported by Thomas Forell)
1087 - improved signal handling for gui, now it rereads conf on SIGHUP
1088 - new dbtool command: cdb (create database)
1089 - switch from argtable to gengetopt
1090 - major code cleanup and speed improvements
1091 - fix several potential buffer overflows
1092 - many small fixes and cleanups
1098 - easy stream_defs syntax
1099 - sdl_gui can display images associated to the file being played
1100 - Major feature enhancements for icc_gui including dynamic text
1101 placement and the top/bottom window design
1102 - vrfy/clean now also checks for NULL values in attributes as
1103 well as for invalid picture pointers
1104 - fix long outstanding case sensitivity bug
1105 - many small fixes and cleanups
1111 - sdl gui runs much faster
1112 - new dbtool command: ca (copy attributes)
1113 - count and display number of times the song has been played
1114 - new feature: scoring
1115 - command line options for sdl_gui
1116 - simpler syntax of streams file
1117 - decrease network traffic of stat
1119 - many small fixes and cleanups
1125 - new server command: ns (next stream)
1126 - new icc_gui command: c (change stream)
1128 - stat shows also id3 tag info
1130 - log flodding bug fixed
1131 - many small fixes and cleanups
1137 - colors for icc_gui
1138 - icc_gui sets volume directly (linux only)
1139 - proper locking that fixes some races
1140 - fix security bug that caused commands to be executed even
1141 with unsufficient permissions
1142 - new command: hup to make all servers reread their configuration file
1143 - icecast meta data streaming
1144 - many small fixes and cleanups
