4 ---------------------------------------------
5 0.5.2 (to be announced) "orthogonal interior"
6 ---------------------------------------------
8 The new sync filter, the AES_CTR128 stream cipher and the overhauled
9 network code are the highlights of this release.
11 - The new sync filter synchronizes playback between multiple
13 - Connections between para_server and para_client are now
14 encrypted by means of AES rather than RC4 if both sides
15 support it. RC4 is still available as a fallback. This
16 feature is fully transparent, i.e. no command line options
17 are necessary, and a client linked against openssl can
18 speak with a server linked against libgcrypt and vice versa.
19 - Major cleanup of the networking subsystem.
20 - Improved user manual.
21 - Minor fixes to avoid clang warnings.
23 ------------------------------------------
24 0.5.1 (2013-12-20) "temporary implication"
25 ------------------------------------------
27 Lots of fixes and improvements all over the place, and a major overhaul
30 - Audiod improvements and fixes.
31 - Buffer tree robustness improvements.
32 - Cleanup of the mood subsystem.
33 - Fixes and cleanups for the flac decoder.
34 - Latency improvements for the ogg/opus decoder.
35 - Crypto support is now optional. On systems without
36 openssl/gcrypt, the build succeeds but para_server,
37 para_audiod, para_client won't be built.
38 - The build system now works for cross-compile setups.
39 - The dependency tree has been flattened, which speeds up
40 builds and avoids to recreate the man pages on every change.
41 - The error code helper has been rewritten from perl to C,
42 which further improves build time.
43 - Many small bugs in the build system have been identified
46 ----------------------------------------
47 0.5.0 (2013-08-23) "invertible validity"
48 ----------------------------------------
50 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
52 - The sideband compatibility code has been removed, hence
53 sideband connections (introduced in 0.4.11) are now mandatory.
54 - Addblob commands can produce output.
55 - The stat command no longer sends garbage when para_server was
56 compiled against libgcrypt.
57 - Dependencies for gengetopt files are computed automatically.
58 This eliminates a constant source of build bugs.
59 - The setatt command now accepts file name patterns rather than only
61 - overview.pdf is now based on dia, a simple diagram creation program.
62 The new version is much more detailed and contains descriptions of
63 the various programs of the paraslash package.
64 - The separator of all multi-word options has been changed from
65 underscore to dash. For example --log_color becomes --log-color.
66 - Overhauled web pages and the new logo.

71 --------------------------------------
72 0.4.13 (2013-07-29) "spectral gravity"
73 --------------------------------------
75 One more 0.4.x release before the API-breaking changes for 0.5.0 go
76 in. The main features of this release are the ogg/opus audio format,
77 and UTF-8 support, but it includes also tons of other improvements
78 and fixes all over the place.
80 - New audio format: ogg/opus.
81 - UTF8 support for para_gui and the mp3 audio format handler.
82 - Scheduler improvements and fixes.
83 - The obsolete gettimeofday() function has been replaced
84 by clock_gettime() on systems which support it.
85 - Speed and usability improvements for para_gui.
86 - para_client now restores the fd flags of stdin and stdout
88 - Improved manual pages.
89 - Consistent version strings for all executables.
90 - Reduced dependencies on generated files result in fewer
91 recompilations on changes.
92 - Performance improvements for the compress filter.
93 - Improved downloads web page.
95 -----------------------------------------
96 0.4.12 (2012-12-20) "volatile relativity"
97 -----------------------------------------
98 The new command line player, the resample filter, ALSA support for
99 para_fade, and the improved build system are the highlights of this
100 release which probably marks the end of the 0.4.x series.
102 - The afh receiver and the para_play executable.
103 - The resample filter: A sample rate converter based on
105 - The "versions" directory has been removed from the master
106 branch. The tarballs of the old releases are now available
107 in the new "releases" branch.
108 - Overhaul of the build system: All generated files are now
109 written to the "build" directory.
110 - The modular mixer API and the alsa mixer.
111 - Minor fixes for the osx writer.
113 --------------------------------------
114 0.4.11 (2012-07-20) "mutual diversity"
115 --------------------------------------
117 The major feature in this release is the new sideband API for
118 client-server communication. This API will be used exclusively starting
119 with 0.5.0, which breaks backward compatibility but allows to get rid
120 of quite some compatibility code. Other noteworthy changes include
121 decoder latency improvements and a long-standing bug fix for the
124 - Sideband connections: If both para_server and para_client
125 support this feature, data is sent as a multiplexed stream.
126 - The --no_default_filters option of para_filter has been
128 - Several fixes and latency improvements to various decoders.
129 - The ALSA writer now limits the prebuffer time to 500ms.
130 - Documentation improvements.
131 - Overhaul of the command_util.sh script.
132 - Fixes for some minor problems found by the clang analyzer.
133 - Compiles (almost) without warnings on gcc-3.
134 - Robustness improvements of the buffer tree code.
136 ------------------------------------------
137 0.4.10 (2012-03-30) "heterogeneous vacuum"
138 ------------------------------------------
140 Nothing earth-shaking in this release, but quite a few usability
141 improvements and the usual mix of cleanups and fixes.
143 - The --no_default_filters option of para_filter has been
144 deprecated. It still works but has no effect and will be
145 removed in the next version.
146 - para_gui now prints also the stderr output of the executing
147 command in the bottom window.
148 - Cleanup and consolidation of the various wrappers for
149 write(), writev(), send() and friends.
150 - The obscure error messages on mmap() failures have been
151 replaced by meaningful messages. This affects mainly
153 - para_audioc: Cleanups and memory leak fixes.
154 - Test 0004-server no longer fails if para_server is not
156 - New configure options: --with-id3tag-{headers,libs}.
158 -------------------------------------
159 0.4.9 (2011-12-06) "hybrid causality"
160 -------------------------------------
162 Support for another audio format, interactive mode for para_client
163 and para_audiod and many small improvements/fixes all over the place.
165 - Support for flac, the free lossless audio codec.
166 - Fix for an endless loop in the mp3 decoder for certain
168 - When executed without specifying a command, para_client
169 and para_audioc start an interactive shell (requires
170 libreadline being installed). The interactive mode offers
171 full tab completion and command line history.
172 - autogen.sh now detects a distcc setup and adjusts the
173 parameter for the -j option of make accordingly.
174 - Shared memory areas are no longer restricted to 64K. We now
175 detect the maximal size of a shared memory area at runtime.
176 - cleanup of the internal uptime API.
177 - para_server prefaults the mmapped audio file to avoid
178 delays on slow media.
179 - A new test for the test-suite that exercises the
180 communication between para_server and para_audiod.
181 - The alsa writer eats up less CPU cycles when configured to
183 - Simplified and unified receiver code.
185 - Commands which print a list of matching audio files now
186 emit a meaningful error message if no audio file matched the
189 --------------------------------------
190 0.4.8 (2011-08-19) "nested assignment"
191 --------------------------------------
193 Gcrypt support, the overhauled osx writer and regex format specifiers
194 are the highlights of this release.
196 - support for libgcrypt as a drop-in replacement for openssl.
197 Run configure --enable-cryptolib=gcrypt to link against
198 libgcrypt. The two crypto implementations are compatible to
199 each other, i.e. a para_client executable linked against
200 gcrypt can connect to para_server linked against libssl
202 - Rewrite of the osx writer (output plugin for Mac OS).
203 - audiod: The format specifier for receivers, filters and
204 writers is now treated as a regular expression. This allows
205 to replace 5 lines in the config file (one for each audio
206 format) by one single line. See the manual for details.
207 - The *.cmdline.[ch] files are no longer contained in the released
208 tarballs. This reduces the size of the tarballs but requires
209 gengetopt to build the tarball.
210 - Compiles cleanly also with llvm/clang.
211 - Corrupt mp3 files are handled more gracefully.
212 - The alsa writer uses poll fds instead of computing timeouts.
213 - Cleanup of the generic writer API.
214 - sched: Optimized zero timeouts.
215 - vss timeout cleanups.
216 - oggdec fixes and improvements.
218 --------------------------------------
219 0.4.7 (2011-06-01) "infinite rollback"
220 --------------------------------------
222 The new ao writer, support for ssh RSA keys and a couple of other
225 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
226 platforms through the libao audio library.
227 - Support for RSA keys generated with ssh-keygen.
228 - configure: improved options for ogg/vorbis/speex.
229 - The git version reported by --version always matches HEAD.
230 - The autogen script detects the number of processors and
231 runs a parallel make if possible.
232 - Major cleanup of the crypto API.
233 - Documentation updates.
235 ------------------------------------------
236 0.4.6 (2011-03-31) "deterministic entropy"
237 ------------------------------------------
239 Lots of ogg/vorbis improvements, the new test suite, enhancements
240 for para_gui and a fair amount of other bug fixes.
242 - For DCCP/OGG streams the audio file header is only sent once
243 at the beginning of the stream rather than periodically
244 every five seconds. This reduces network traffic and the
246 - The vorbis comment header is replaced by an empty dummy header
247 before the header is sent over the network. This also results in
248 less network traffic and smaller FEC groups.
249 - The new "test" make target allows to perform some sanity checks prior
250 to installing the package.
251 - ogg timing fixes and performance improvements
252 - Scheduler improvements
253 - Proper exit codes for para_write
254 - para_gui: New option --theme to select a startup theme. Several
255 other improvements and fixes.
256 - aacdec error message cleanups
257 - simplified color error handling
259 --------------------------------------------
260 0.4.5 (2010-12-17) "symmetric randomization"
261 --------------------------------------------
263 Bug fixes, internal cleanups and variable-sized FEC slices.
265 - Contains a fix for an invalid-free-bug in the ogg audio format
267 - Switching off the DCCP sender works again.
268 - para_audiod handles crashes of para_server more robustly.
269 - Internal scheduler and writer cleanups.
270 - Reduced latency due to variable-sized FEC slices.
271 - Improved documentation and error diagnostics.
272 - The build of para_server is now optional, allowing the build
273 to succeed in case libosl is not installed.
275 ------------------------------------------
276 0.4.4 (2010-08-06) "persistent regularity"
277 ------------------------------------------
279 Support for yet another audio format, para_write improvements and
282 - Support for the speex codec.
283 - Support for sample formats other than 16 bit little endian.
284 - error2.h is now created by a perl script which speeds up configure
286 - Fix a bug in the aac decoder which could lead to segfaults in
287 para_filter/para_audiod.
288 - Fixes for autoconf-2.66.
290 ----------------------------------------
291 0.4.3 (2010-07-05) "imaginary radiation"
292 ----------------------------------------
294 Many improvements for the DCCP and the UDP transport, the new user
295 manual and the usual mix of bug fixes and internal improvements.
297 - FEC support for the DCCP sender (Gerrit Renker). The new
298 --dccp_max_slice_size, --dccp_data_slices_per_group and
299 --dccp_slices_per_group options can be used to set the FEC
300 parameters for the DCCP transport.
301 - DNS lookups for UDP targets (Gerrit Renker).
302 - The new user manual replaces the README, README.afs, REQUIREMENTS
303 and INSTALL documents.
304 - Fix an end-of-file detection bug in the oggdec filter.
305 - The new nonblock API.
306 - Both options of the oggdec filter have been removed.
307 - New debug mode for the internal scheduler.
309 ------------------------------------------
310 0.4.2 (2010-04-23) "associative expansion"
311 ------------------------------------------
313 It's been some time since the last release, but finally here is
314 paraslash-0.4.2. The bulk of the changes comes from the new buffer
315 tree API, but there are changes all over the tree. Mainly performance
316 and usability improvements, but also quite some bug fixes.
318 - The new buffer tree API.
319 - DCCP: Support for CCID negotiation (Gerrit Renker).
320 - UDP robustness fixes.
321 - The --bufsize option for mp3dec is gone as it no longer makes sense
322 for the new buffer tree API.
323 - Fix audible buffer underruns for wma streams.
324 - The alsa writer no longer prints meaningless underrun durations.
325 - audiod: Defaults work also for udp streams. If no filter is
326 given for an audio format that is received via upd, fecdec is
327 automatically added as the first filter (along with the decoder).
329 ---------------------------------------
330 0.4.1 (2009-12-22) "concurrent horizon"
331 ---------------------------------------
333 Support for another audio format, minor feature enhancements and lots of bug
334 fixes. All fixes that have been accumulated in the maint branch (in particular
335 those mentionened in the 0.3.6 release notes) appear in this release as well.
338 - new afh option: --human to activate human-readable output.
339 - new server/audiod option: --log-timing to print timing information.
340 - build system improvements.
341 - source code documentation updates.
343 -------------------------------------
344 0.3.6 (2009-12-07) "cubic continuity"
345 -------------------------------------
347 Quite a few bugs have been found and fixed since 0.3.5, so here's
348 another 0.3.x release. No new features.
350 - Always check return value of malloc().
351 - ogg vorbis/FEC: Do not write garbage after the audio file header.
352 - exit if root privileges could not be dropped.
353 - FEC: Fix computation of extra slices.
354 - oss: Fix check for empty input buffer.
355 - Avoid buffer underruns due to filter chain output buffer constraints.
356 - server: Fix assignment of afs_pid.
357 - Don't panic if the afs database contains unknown audio formats.
358 - http/dccp: Do not send the audio file header twice.
359 - FEC: Timing improvements.
361 ----------------------------------------------
362 0.4.0 (2009-11-10) "simultaneous independence"
363 ----------------------------------------------
365 Two significant changes which require the new version number: The
366 improved authentication dialog and the fact that the database code
367 has been moved to a library, libosl. To use the new version, you have
368 to generate new RSA keys, see INSTALL for details. A shell script is
369 provided for conversion of the 0.3 database to the new 0.4 format.
371 - stronger crypto for client authentication
372 - the database code has been moved to a library
373 - improved status item handling
374 - cleanup of the build system
375 - The "-V" option now also prints the git version
376 - the new parser-friendly listing mode for the ls and stat commands
377 - mandatory rc4 encryption
378 - major audio format handler cleanups
379 - (id3,...) tags are no longer stored as a combined string in the database
380 - new mood methods: artist_matches, title_matches, comment_matches,
381 album_matches, year_maches, year.
383 --------------------------------------------
384 0.3.5 (2009-09-21) "symplectic separability"
385 --------------------------------------------
387 Full client support for *BSD Unixes, complete re-write of the ogg
388 vorbis audio format handler, various improvements all over the place
389 and the usual mix of bugfixes. This release marks the end of the 0.3
390 series if no serious problems show up.
392 - the new oss writer (supported on *BSD and Linux)
393 - rewrite of the ogg vorbis audio format handler. It's
394 recommended to replace the chunk tables of existing ogg
395 vorbis files in the afs database by re-adding these files
397 - support for netmask subsets (Gerrit Renker)
398 - the new prebuffer filter
399 - improved signal handling
400 - variable fec output buffer size
401 - improved FEC timing fixes audible buffer underruns in UDP mode
402 - --log_color actually works
403 - new ls option: -d (print dates as seconds after the epoch)
404 - update to gengetopt 2.22.2
405 - support for RSA keys of size > 512 bits
406 - new option "mixer_channel" for para_fade
408 -----------------------------------------
409 0.3.4 (2009-05-07) "elliptic inheritance"
410 -----------------------------------------
412 The new udp sender, forward error correction, colored logs and various
413 other improvements. As the udp sender does not depend on any special
414 libraries, it is built unconditionally.
416 - The udp sender replaces the ortp sender. The new code uses forward
417 error correction to protect against packet losses. Many thanks to
418 Gerrit Renker for providing ipv6 support.
419 - The default port for udp streaming now defaults to 8000, like
420 for the http and the dccp senders/receivers.
421 - Loglevels are now specified as symbolic names, e.g.
423 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
424 - para_server/para_audiod: Color support for log messages.
425 - new options for mp3dec: --ignore-crc, --bufsize
426 - new audiod option: --config-file.
427 - gengetopt cleanups.
428 - Improved help/man pages: The documentation of para_audiod,
429 para_recv, para_filter and para_write now also contains
430 all options of the available receivers/filters/writers. The
431 man page of para_fade contains a description of the different
433 - More source code documentation.
436 --------------------------------------------
437 0.3.3 (2008-12-01) "axiomatic perspectivity"
438 --------------------------------------------
440 Internal code cleanups, bug fixes, improved tag handling and the new
441 amplification filter.
443 - para_server uses the generic scheduling code.
444 - overhaul of the virtual streaming system.
445 - mp3: id3 version 2 support via libid3tag (optional)
446 - ogg: vorbis comment support.
447 - aac meta info support.
448 - mp3 audio format handler cleanups.
449 - new filter: "amp" to amplify the amplitude of the audio stream
450 - new status item/database entry: amplification. It is
451 used by the amp filter to pre-amplify the audio stream.
452 - fix a close-without-open bug in para_write.
453 - fix a bug in com_init() which was introduced in 0.3.2.
454 - better error diagnostics for para_client.
456 -----------------------------------------
457 0.3.2 (2008-04-11) "probabilistic parity"
458 -----------------------------------------
460 The new para_afh executable, scheduling and documentation improvements.
462 - new ls option: -lc (list chunk table)
463 - new executable: para_afh, the stand-alone audio file handler tool
464 - afs commands can send output more than SHMMAX (32MB on Linux). This
465 also reduces the memory usage of commands that produce large amounts
467 - major scheduler and audiod cleanups.
468 - more detailed and much nicer man pages.
470 ---------------------------------------
471 0.3.1 (2008-02-23) "liquid interaction"
472 ---------------------------------------
474 A mix of cleanups, bug fixes, improvements, and some new features. No
475 significant changes to the new database (osl) code, which is generally
478 - Share some similar/duplicate code between the http and the
480 - Generic access control lists for paraslash senders.
481 - dccp sender: Access control lists, connection limiting and support
482 for the allow,deny,on,off,help sender commands.
483 - The default dccp port changed from 5001 to 8000 (suggested by
485 - para_server starts even if not all public keys could be loaded.
486 - Audiod performance improvements.
487 - fix a bug in the "off" command of the http sender.
488 - fix some fd and memory leaks.
489 - Update to gengetopt-2.22.
491 -------------------------------------
492 0.3.0 (2008-01-12) "solar saturation"
493 -------------------------------------
495 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
498 Usually one might expect lots of new features AND a big increase in size
499 for a major release like this.
501 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
502 ever. The decrease in size is mostly due to the removal of some
503 graphical tools (which were only quick hacks anyway). But also the
504 fact that the mysql code is gone cuts down the size a bit.
506 Being independent of mysql comes at a cost: The fact that paraslash
507 now contains its own database (the object storage layer, osl) increases
508 the (stripped) binary size of para_server by ~50K on i386.
510 - no more restrictions on unique basenames.
511 - independent of mysql: The new self-contained object
512 storage layer (osl) replaces the mysql database.
513 - New executable para_fsck: Check integrity of osl tables.
515 - Reliable audio file move/rename detection.
516 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
517 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
519 - the new osl-based audio file selector (afs) replaces the random,
520 the playlist and the mysql selector of paraslash-0.2.x.
521 - IPv6 support (thanks to Gerrit Renker).
522 - paraslash-0.2.x streams are now called "moods". Writing
523 0.3.x-mood definitions should be both easier and more
524 powerful than writing 0.2.x-stream definitions.
525 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
526 been removed. The world is a better place without them. However,
527 para_gui is still there.
528 - afs tracks audio file selection also in playlist mode.
529 - few easy-to-use afs commands replace the many not-so-easy-to-use
530 mysql commands (and are available also in playlist mode).
531 - Improved error subsystem.
532 - The earth-shaking new logo.
534 -----------------------------------------
535 0.2.17 (2007-11-20) "isotropic threshold"
536 -----------------------------------------
538 Mainly bugfixes and cleanups in this version which marks the end of
539 the 0.2.x series if no serious bugs show up after the release.
541 - mysql_selector: fix a locking bug.
542 - universal chunk queueing.
543 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
545 - be more carful wrt. signed vs. unsigned argument passing.
546 - cleanup error.h and fix some references to invalid error
548 - update to gengetopt-2.21.
549 - update to ortp-0.13.1.
550 - autoconf: extend checks for headers, library functions and
551 compiler characteristics.
552 - Fix streaming of large mp3 files.
553 - Fix an off-by-one bug in playlist handling.
555 --------------------------------------
556 0.2.16 (2007-04-05) "neural discharge"
557 --------------------------------------
559 The main change in this release is the major audio format handler
560 cleanup which removes some similar/duplicate code and makes it easier
561 to implement plugins for other audio formats. Of course, the usual mix
562 of other improvements/changes/bugfixes also made it into the release.
564 - simplified audio format handlers (most of the handling functions
565 were moved one layer up to the virtual streaming system).
566 - para_server uses mmap to read audio files
567 - repositioning of mp3 streams is much faster, in particular for
568 jumping near the end of large mp3 files.
569 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
571 - fix a bug in para_filter that caused decoding of aac files
572 to start only after a few seconds.
573 - fix osx_writer hangs
574 - simplified dccp code (thanks to Gerrit Renker)
575 - the compress filter works also on big endian systems (ppc)
577 -----------------------------------------
578 0.2.15 (2007-02-16) "inductive resonance"
579 -----------------------------------------
581 Minor improvements, more documentation and a bunch of bug fixes.
583 - para_server: The server.users file is only read once on server
584 startup rather than for each connection
585 - mp3dec: Fix decoding of corrupt mp3 files
586 - afs (audio file sender) is now called vss (virtual streaming
587 system). Consequently, the permission flags specified in
588 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
589 become VSS_READ and VSS_WRITE respectively.
590 - para_audiod/para_filter: Fix a bug that caused the last chunk
591 of audio data not being written under certain circumstances
592 - audiod: compute the difference of server time and local time
594 - para_server/para_audiod: Fix some memory leaks
595 - documentation improvements
596 - configure.ac: fix checks for para_krell
599 -------------------------------------------
600 0.2.14 (2006-10-15) "transient singularity"
601 -------------------------------------------
603 The only major enhancement of this version is the osx writer which completes
604 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
605 until now for reasons beyond the scope of this changelog entry.
607 - new output plugin for Mac Os: the osx writer
608 - rename configure command line options from --enable-xxx-headers to
609 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
610 - configure: new command line options: --with-mad-headers,
611 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
612 - some robustness fixes
613 - dymamic audio format recognition for audiod
614 - para_server: new command line option: --autoplay_delay
615 - para_audiod: new command line option: --clock_diff_count
617 ---------------------------------------
618 0.2.13 (2006-07-14) "sonic convolution"
619 ---------------------------------------
621 A bunch of new features and core changes.
623 - the new paraslash scheduler, short and sweet.
624 - Support for m4a/mp4 files via the new aac audio format
625 handler/filter (requires libfaad).
626 - each writer has its own command line parser, just like
627 para_recv and para_filter.
628 - para_client and para_audioc use the error subsystem
629 - writers are integrated in para_audiod (currently linux-only)
630 - para_client is integrated in para_audiod
631 - random/playlist selector: improved info strings
632 - new audiod commands: tasks, kill
633 - update to libortp-0.10.1
634 - para_fade: wake time defaults to 8 hours from now
635 - update to autoconf-2.60
637 ------------------------------------------
638 0.2.12 (2006-05-12) "oriented abstraction"
639 ------------------------------------------
641 Many user-visible changes in this release and lots of new
645 - the new optional dccp sender/receiver. It uses the datagram
646 congestion control protocol. You'll need a fairly new kernel
648 - paraslash works on Mac OS X (thanks to Gerd Becker)
649 - para_play renamed to para_write
650 - modular output plugin design (writers) for para_write
651 - new file_writer output plugin for para_write
652 - compress filter speed improvements
653 - update to libortp-0.9.1
654 - update to gengetopt-2.17rc
655 - para_client no longer depends on libreadline (as the
656 code for the interactive mode was removed).
657 - gcc-2-95 is no longer a supported compiler. It may still
658 work, but it gets no more testing.
659 - the tarball no longer contains the screenshot images which
660 reduces its size quite a bit.
661 - configure: new command line options: --enable-mysql-headers
662 and --enable-mysql-libs
664 ------------------------------------
665 0.2.11 (2006-03-11) "atomic duality"
666 ------------------------------------
668 Here it is, the first paraslash release developed with git. There
669 are fairly many user-visible changes in this release. As two out of
670 the three "database tools" of paraslash don't use a database at all,
671 they are now called "audio file selectors" instead.
674 - the cdt command (change database tool) becomes chs (change
676 - no more colon separators: The syntax of some options of
677 para_audiod and para_filter have changed. Use --help for
678 more info (and some examples).
679 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
680 - switch from cvs to git (should've done that earlier)
681 - the new ipc subsystem
682 - new audio file selector: playlist
683 - para_server: the dopey selector is now called "random",
684 and is the default selector. Use the --selector option to
685 choose another selector at startup, or the chs command to
686 change the selector at runtime.
687 - X86_64 fixes (thanks to Steffen Klassert)
690 --------------------------------------
691 0.2.10 (2006-02-17) "cyclic attractor"
692 --------------------------------------
694 Huge documentation update, a scrollable window for para_gui, ortp
695 improvements, and of course many small fixes not mentioned here.
696 The diffstat below is rather misleading as most insertions are due
697 to the new source documentation.
700 - para_server also uses the new error subsystem
701 - lots of new documentation (UTSL)
703 - keysyms for cursor keys and for next/previous page keys
704 - scrollable output window
705 - new internal commands: scroll up/down, page up/down
706 - fix color of command output.
707 - ortp: the --chunk_time and --header flags are no longer needed
708 for para_recv/para_audiod as this information is now encoded in
709 each rtp packet sent by para_server.
711 -------------------------------------------
712 0.2.9 (2006-01-24) "progressive turbulence"
713 -------------------------------------------
715 Internal audiod receivers/filters, the new error subsystem and
716 a lot of small improvements.
718 - para_recv and para_filter are integrated into the para_audiod
719 binary, i.e. audiod no longer spawns a new process for
720 each receiver/filter. As para_recv and para_filter might be
721 useful as standalone programs, they still get built (linked
722 against the same object files that are also used for audiod).
723 - further ortp timing improvements should reduce the CPU usage
724 of the ortp receiver.
725 - improved audio grabbing. The 'grab' command of para_audiod
726 has its own set of command line options. Read the output of
727 "para_audioc help grab" for more info.
728 - oggdec: configurable input prebuffer size.
729 - the new error subsystem gives better error diagnostics
730 and reduces code size.
732 -----------------------------------------
733 0.2.8 (2006-01-02) "dynamic accumulation"
734 -----------------------------------------
736 The new modular filter design and the para_play-hangs bugfix.
738 - new executable: para_filter. It combines para_mp3dec,
739 para_oggdec and para_compress. It also adds a further filter
740 type, wav, that just inserts a wave header at the desired point
741 of the filter chain. All 'piping' is done in-memory (i.e. no
742 read/write operations are used).
743 - para_play: fix a stupid bug that caused it to hang under
744 certain circumstances.
746 -------------------------------------------
747 0.2.7 (2006-12-27) "transparent invariance"
748 -------------------------------------------
750 Not many user-visible changes but a fair amount of internal improvements.
753 - The http sender buffers data if it can not be sent
754 out immediately (because the socket is not writable). This
755 should prevent para_server from shutting down the connection
756 too early on a loaded network.
757 - para_play also prebuffers data if it is told to start at a
758 future time by the --start_time option.
759 - The return of para_recv: It combines para_ortp_recv and
760 para_http_recv. Use the --receiver option to switch between
761 the two. para_recv builds without libortp, but contains
762 only the http receiver in this case.
763 - update to ortp 0.8.1. As this ortp release contains incompatible
764 changes, para_recv-0.2.7 won't link against older ortp libs.
765 - improved ortp timings.
766 - use of gcc-extensions that #define away for non-gcc and
769 -------------------------------------------
770 0.2.6 (2005-10-29) "recursive compensation"
771 -------------------------------------------
773 Transparent session encryption (uses openssl's Alleged RC4 cipher),
774 the internal find command and several other improvements and cleanups.
776 - Encrypt the session if encryption is requested by the client
777 (default for para_client 0.2.6). This is backwards
778 compatible, so older clients can still connect to para_server
779 0.2.6. Use the new client option --plain to request an
780 uncrypted session (off by default, must be set to on in
781 order to connect to para_server 0.2.x with 0 <= x <= 5).
782 - para_server uses an internal function to locate audio files
783 rather than calling find(1). The server option
784 --mysql_audio_file_dir replaces --mysql_find_cmd.
785 - documentation update
787 - header file cleanup
788 - para_client code cleanup
789 - para_gui: faster display of output of display commands
791 ------------------------------------------
792 0.2.5 (2005-10-13) "aggressive resolution"
793 ------------------------------------------
795 This release adds internal senders, i.e. no more external programs are
796 spawned for sending out the audio data. There are two different senders
797 available: The http sender and the ortp sender (former para_send which
798 is no longer needed).
800 The new sender code has a plugin-like design so it can be easily
801 extended should there be be any future need for supporting another
802 network streaming protocol. All senders are completely independent of
803 each other. In particular, the http and the ortp sender can operate
806 - new server command: sender to control senders at runtime.
807 Read the output of "para_server -h" and "para_client help
808 sender" for more information.
809 - para_recv renamed to para_ortp_recv
810 - new executable: para_http_recv, a simple command line
812 - major afs/mp3/ogg code simplifications due to internal
814 - ogg timing improvements
815 - fix several minor memory leaks (found by valgrind)
816 - empty stream definitions work again
817 - com_ne(): ignore errors on remove
818 - audiod: fix segfault on server restart
820 ---------------------------------------
821 0.2.4 (2005-09-21) "toxic anticipation"
822 ---------------------------------------
824 Several small improvements, fixes and the new grab command.
827 - new command: "grab" to grab the output of the stream reader
828 or any filters. Read the output of "para_audioc help grab"
829 for more information.
832 - audioc: new command line option: --bufsize to specify a
833 buffer size different from the default size 8192.
834 - improved error diagnostics for para_play.
835 - new configure option: --enable-ssldir so search for openssl in
837 - sdl_gui: Make it look nice again for 1024x768
838 - server: report total size of memory allocated with sbrk by malloc,
839 new command line option: --announce_time
841 -----------------------------------------
842 0.2.3 (2005-09-01) "hydrophilic movement"
843 -----------------------------------------
845 Two new executables and major feature enhancements.
847 - audiod filters: It is now possible to specify arbitrary many
848 (including none) filters for each supported audio
849 format. This can be used e.g. for normalizing volume,
850 transforming or grabbing the audio stream, or for using
851 visualizers. Read the output of "para_audiod -h" for the
852 syntax of the new --filter_cmd option.
853 - new executable: para_play, a tiny alsa player. It
854 can play wave files or raw pcm (16 bit little endian)
856 - new executable: para_compress, a dynamic range compressor
857 intended to keep audio output at a consistent volume. Derived
858 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
859 - audiod: New option: --stream_delay. This can be used in
860 a local network to syncronize the audio output of all
861 clients that play the same stream.
863 ------------------------------------------
864 0.2.2 (2005-08-19) "tangential excitation"
865 ------------------------------------------
867 Mostly internal changes in this release, but also some new commands
868 for the mysql database tool.
870 - cleanup exec.c, fix para_exec bug
871 - compile time loglevel (log messages below the given level
872 won't be compiled in, which reduces the size of the
874 - new log macros that shorten the size of the source code.
875 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
876 to send only zeros. With this workaround, para_audioc works
878 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
879 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
880 (new entry), "snp" (set numplayed). Read the manual for more
883 ---------------------------------------
884 0.2.1 (2005-08-15) "surreal experience"
885 ---------------------------------------
887 Here comes paraslash-0.2.1. It contains a couple of new features and,
888 surprise, only minor bug fixes.
890 - kill noisy mp3 debug message
891 - cleanup of the build system
892 - para_server and para_client directly use the crypto routines
893 of the openssl library rather than invoking the openssl command
895 - server/audiod: new option --user to switch to the given user
896 when invoked as root. Read the output of "para_server -h" for
898 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
899 status. Default: "para_audioc stat"
900 - sdl_gui: new option --pic_cmd to be used to download the picture.
901 Default: "para_client pic"
902 - audiod: 5 slots ought to be enough for everybody
903 - audiod: new status item: Uptime, kill hup command
905 ------------------------------------------
906 0.2.0 (2005-08-06) "distributed diffusion"
907 ------------------------------------------
909 After several month of increased development activity, paraslash-0.2.0
910 has arrived. It contains many new features and is much more
911 self-contained than the old 0.1.x series. Enjoy!
914 - para_server: fix hang on song change and crash on sighup.
915 Speed up mysql queries. The DIR_LIKE macro is gone.
916 - new executables: para_audiod, the local audio daemon that
917 starts playback (uses SCM_CREDENTIALS socket magic) and
918 para_audioc, the corresponding client.
919 - new executables: para_mp3dec/para_oggdec, two really teensy
920 decoders. para_mp3dec is based on libmad, para_oggdec requires
922 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
923 they are now called para_send and para_recv respectively.
924 - documentation updates
925 - para_gui is themable. For now there is the default theme that
926 looks as before and the simple theme: blue and easy.
927 - gui: audio streaming is now handled by audiod. Time display shows
928 playback time rather than streaming time
929 - slider: update to libzmw-0.2.0
930 - para_krell: fix crash on server shutdown
931 - switch from gzip to bzip2
933 ----------------------------------------
934 0.1.7 (2005-04-18) "melting penetration"
935 ----------------------------------------
937 The main change in this release is clearly the oggvorbis rewrite,
938 but there are also lots of smaller changes. If you intend to use both
939 the mp3 and the ogg plugin, it is recommended to use software mixing,
940 e.g. the dmix plugin which is provided by ALSA.
942 - new executables: para_ovsend and para_ovrecv for sending/receiving
943 oggvorbis files via rtp. Requires the open rtp library. Get it at
944 http://www.linphone.org/ortp/
945 - rewrite of the ogg_vorbis core code
946 - configure detects libzmw and, if detected, includes
947 para_slider to the list of binaries to be built by make
948 - server stream writers read from their associated fifo rather
950 - slider: two new sliders, lastplayed and numplayed
951 - fix nasty double free bug which caused random segfaults in case of
952 mp3 files with invalid header information
953 - gui: new command line option: --stream_timeout=seconds to
954 deactivate a slot if it is idle for that many seconds (default=`5')
957 ---------------------------------------
958 0.1.6 (2005-03-05) "asymptotic balance"
959 ---------------------------------------
961 Only little user-visible changes in this release. Mainly bugfixes and
962 core code cleanup. This is probably the most stable version ever if you
965 - fix several memory leaks
966 - rename default name of mysql database from "music" to "paraslash".
967 Use para_server's --mysql_database option if you do not want to
968 rename your old database.
969 - rework ogg vorbis code
970 - make update command work on mysql servers with LOCAL_INFILE
972 - gui: improved stream I/O (slots)
973 - simplified audio format API
974 - para_pob_ogg is gone
976 ------------------------------------
977 0.1.5 (2004-12-31) "opaque eternity"
978 ------------------------------------
980 Let's slide gently into the new year.
982 - new: para_slider (not built automatically, type "make
983 para_slider" to build). A toy for those who always felt that
984 creating stream definitions is difficult. See screenshots,
985 README and FEATURES for more info.
986 - improved signal handling. Fixes server segfault on SIGHUP
987 for linux kernels newer than Aug 24 2004 and makes para_gui
989 - reload database tool on SIGHUP
990 - improved help message for sl
991 - do not log "broken pipe" messages as errors. They are
993 - fix wrong error message on permission errors
995 -----------------------------------------
996 0.1.4 (2004-12-19) "tunneling transition"
997 -----------------------------------------
999 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
1000 Hopefully, most of them got wiped out with this release. Some
1001 enhancements went also in.
1003 - improved error diagnostics for all commands
1004 - stradd/picadd: overwrite previous contents if entry already
1005 exists, rather than returning errors
1006 - stradd: use current stream if invoked without args
1007 - faster (and hopefully more stable) ogg-vorbis handling
1008 - para_krell: reap children to avoid zombie-flooding in case
1009 no server is running
1010 - si: report also server pid
1011 - server: don't busy-loop if dbtool reports only invalid files.
1012 - gui: CTRL+C works again, fix stream_read command line option
1014 - fix mysql dbtool startup in case no database exists
1015 - many small fixes and cleanups
1017 ---------------------------------------
1018 0.1.3: (2004-12-10) "vanishing inertia"
1019 ---------------------------------------
1021 Starting from this release, the database tools are integrated in the
1022 server binary. This decreases server startup time, reduces code size
1023 and speeds up database commands. However, the layout of the underlying
1024 mysql database changed only slightly and 0.1.3 should be backwards
1025 compatible in that respect.
1029 - If mysql is not detected at compile time, or fails to init
1030 at runtime, fall back to the dopey database tool which should
1032 - para_dbtool and dbtool.conf are gone. All mysql specific
1033 options are read from server.conf and are prefixed by 'mysql_'.
1034 - new command: cdt (change database tool)
1035 - new command line option: dbtool (choose startup database tool)
1036 - The name of current stream is now stored in the database,
1037 so paraslash remembers its current stream when restarted.
1038 - new command: csp (change stream and play)
1039 - para_gui also reports current database tool and server uptime
1041 -------------------------------------------
1042 0.1.2: (2004-11-28) "spherical fluctuation"
1043 -------------------------------------------
1045 Point release before the big dbtool changes go in.
1047 - dbtool: rename ca to cam (copy all meta data). It now also
1048 copies numplayed and lastplayed time as well as the picture
1050 - fix endless-loop-bug caused by mp3 files with invalid header
1052 -----------------------------------------
1053 0.1.1: (2004-11-05) "floating atmosphere"
1054 -----------------------------------------
1057 - new dbtool command: mbox. Browse your sound-file collection
1058 with your favorite mail reader.
1059 - several small fixes
1061 -------------------------------------
1062 0.1.0: (2004-10-22) "rotating cortex"
1063 -------------------------------------
1065 - fix logging bug for loglevel > VERBOSE
1067 - correct timings for vbr mp3s
1068 - modular audio format support
1069 - ogg-vorbis support (experimental)
1070 - new server option: autoplay
1072 -----------------------------------------
1073 0.0.99: (2004-07-25) "harmonic deviation"
1074 -----------------------------------------
1076 - rename projectname from icc to paraslash (play, archive, rate
1077 and stream large audio sets happily)
1078 - paraslash is no longer restricted to one particular audio
1080 - new dbtool commands (stradd, strq, strdel) for easy stream
1081 managment w/o configuration file. That obsoletes stream_defs
1082 file/config option for dbtool.
1083 - picadd accepts jpeg data from stdin
1084 - new server commands: ps (select previous stream), sc (song change)
1085 - new default pictures for sdl_gui
1086 - gui: new key_map option for binding commands and internal
1087 functions to arbitrary keys, nice help screen, rip out
1088 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1089 show silly logo on startup
1090 - new executables: para_fade for fading volume, para_dbadm for
1091 manipulating attributes
1092 - cdb adds _all_ tables to mysql database
1093 - revised and beautified documentation
1094 - sample dbtool rewritten in C
1097 ---------------------------------------------
1098 0.0.98: (2003-12-26) "incremental smoothness"
1099 ---------------------------------------------
1101 - kick icecast in favour of poc. That removes some races and reduces
1102 core code considerably.
1103 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1104 give finer info on afs' status.
1105 - gui can start decoder (see config options). Further new gui
1106 commands: refresh (^L), jmp (F1-F10)
1107 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1108 terminates gui. This fixes dead instances consuming memory
1110 - new dbtool command: verb for sending verbatim sql queries.
1111 - fix pid_list races (by removing pid_list)
1114 --------------------
1115 0.0.97: (2003-10-26)
1116 --------------------
1118 - installation prefix now defaults to /usr/local
1119 - new commands for gui: snozze, sleep and reread config
1120 - config file for gui and sdl_gui
1121 - fix problems with filenames containing funny characters
1122 (reported by Thomas Forell)
1123 - improved signal handling for gui, now it rereads conf on SIGHUP
1124 - new dbtool command: cdb (create database)
1125 - switch from argtable to gengetopt
1126 - major code cleanup and speed improvements
1127 - fix several potential buffer overflows
1128 - many small fixes and cleanups
1134 - easy stream_defs syntax
1135 - sdl_gui can display images associated to the file being played
1136 - Major feature enhancements for icc_gui including dynamic text
1137 placement and the top/bottom window design
1138 - vrfy/clean now also checks for NULL values in attributes as
1139 well as for invalid picture pointers
1140 - fix long outstanding case sensitivity bug
1141 - many small fixes and cleanups
1147 - sdl gui runs much faster
1148 - new dbtool command: ca (copy attributes)
1149 - count and display number of times the song has been played
1150 - new feature: scoring
1151 - command line options for sdl_gui
1152 - simpler syntax of streams file
1153 - decrease network traffic of stat
1155 - many small fixes and cleanups
1161 - new server command: ns (next stream)
1162 - new icc_gui command: c (change stream)
1164 - stat shows also id3 tag info
1166 - log flodding bug fixed
1167 - many small fixes and cleanups
1173 - colors for icc_gui
1174 - icc_gui sets volume directly (linux only)
1175 - proper locking that fixes some races
1176 - fix security bug that caused commands to be executed even
1177 with unsufficient permissions
1178 - new command: hup to make all servers reread their configuration file
1179 - icecast meta data streaming
1180 - many small fixes and cleanups
