1 --------------------------------------------
2 Noteworthy changes recently merged to master
3 --------------------------------------------
5 - The sideband compatibility code has been removed, hence
6 sideband connections (introduced in 0.4.11) are now mandatory.
7 - Addblob commands can produce output.
8 - The stat command no longer sends garbage when para_server was
9 compiled against libgcrypt.
11 --------------------------------------
12 0.4.13 (2013-07-29) "spectral gravity"
13 --------------------------------------
15 One more 0.4.x release before the API-breaking changes for 0.5.0 go
16 in. The main features of this release are the ogg/opus audio format,
17 and UTF-8 support, but it includes also tons of other improvements
18 and fixes all over the place.
20 - New audio format: ogg/opus.
21 - UTF8 support for para_gui and the mp3 audio format handler.
22 - Scheduler improvements and fixes.
23 - The obsolete gettimeofday() function has been replaced
24 by clock_gettime() on systems which support it.
25 - Speed and usability improvements for para_gui.
26 - para_client now restores the fd flags of stdin and stdout
28 - Improved manual pages.
29 - Consistent version strings for all executables.
30 - Reduced dependencies on generated files result in fewer
31 recompilations on changes.
32 - Performance improvements for the compress filter.
33 - Improved downloads web page.

38 -----------------------------------------
39 0.4.12 (2012-12-20) "volatile relativity"
40 -----------------------------------------
41 The new command line player, the resample filter, ALSA support for
42 para_fade, and the improved build system are the highlights of this
43 release which probably marks the end of the 0.4.x series.
45 - The afh receiver and the para_play executable.
46 - The resample filter: A sample rate converter based on
48 - The "versions" directory has been removed from the master
49 branch. The tarballs of the old releases are now available
50 in the new "releases" branch.
51 - Overhaul of the build system: All generated files are now
52 written to the "build" directory.
53 - The modular mixer API and the alsa mixer.
54 - Minor fixes for the osx writer.
56 --------------------------------------
57 0.4.11 (2012-07-20) "mutual diversity"
58 --------------------------------------
60 The major feature in this release is the new sideband API for
61 client-server communication. This API will be used exclusively starting
62 with 0.5.0, which breaks backward compatibility but allows to get rid
63 of quite some compatibility code. Other noteworthy changes include
64 decoder latency improvements and a long-standing bug fix for the
67 - Sideband connections: If both para_server and para_client
68 support this feature, data is sent as a multiplexed stream.
69 - The --no_default_filters option of para_filter has been
71 - Several fixes and latency improvements to various decoders.
72 - The ALSA writer now limits the prebuffer time to 500ms.
73 - Documentation improvements.
74 - Overhaul of the command_util.sh script.
75 - Fixes for some minor problems found by the clang analyzer.
76 - Compiles (almost) without warnings on gcc-3.
77 - Robustness improvements of the buffer tree code.
79 ------------------------------------------
80 0.4.10 (2012-03-30) "heterogeneous vacuum"
81 ------------------------------------------
83 Nothing earth-shaking in this release, but quite a few usability
84 improvements and the usual mix of cleanups and fixes.
86 - The --no_default_filters option of para_filter has been
87 deprecated. It still works but has no effect and will be
88 removed in the next version.
89 - para_gui now prints also the stderr output of the executing
90 command in the bottom window.
91 - Cleanup and consolidation of the various wrappers for
92 write(), writev(), send() and friends.
93 - The obscure error messages on mmap() failures have been
94 replaced by meaningful messages. This affects mainly
96 - para_audioc: Cleanups and memory leak fixes.
97 - Test 0004-server no longer fails if para_server is not
99 - New configure options: --with-id3tag-{headers,libs}.
101 -------------------------------------
102 0.4.9 (2011-12-06) "hybrid causality"
103 -------------------------------------
105 Support for another audio format, interactive mode for para_client
106 and para_audiod and many small improvements/fixes all over the place.
108 - Support for flac, the free lossless audio codec.
109 - Fix for an endless loop in the mp3 decoder for certain
111 - When executed without specifying a command, para_client
112 and para_audioc start an interactive shell (requires
113 libreadline being installed). The interactive mode offers
114 full tab completion and command line history.
115 - autogen.sh now detects a distcc setup and adjusts the
116 parameter for the -j option of make accordingly.
117 - Shared memory areas are no longer restricted to 64K. We now
118 detect the maximal size of a shared memory area at runtime.
119 - cleanup of the internal uptime API.
120 - para_server prefaults the mmapped audio file to avoid
121 delays on slow media.
122 - A new test for the test-suite that exercises the
123 communication between para_server and para_audiod.
124 - The alsa writer eats up less CPU cycles when configured to
126 - Simplified and unified receiver code.
128 - Commands which print a list of matching audio files now
129 emit a meaningful error message if no audio file matched the
132 --------------------------------------
133 0.4.8 (2011-08-19) "nested assignment"
134 --------------------------------------
136 Gcrypt support, the overhauled osx writer and regex format specifiers
137 are the highlights of this release.
139 - support for libgcrypt as a drop-in replacement for openssl.
140 Run configure --enable-cryptolib=gcrypt to link against
141 libgcrypt. The two crypto implementations are compatible to
142 each other, i.e. a para_client executable linked against
143 gcrypt can connect to para_server linked against libssl
145 - Rewrite of the osx writer (output plugin for Mac OS).
146 - audiod: The format specifier for receivers, filters and
147 writers is now treated as a regular expression. This allows
148 to replace 5 lines in the config file (one for each audio
149 format) by one single line. See the manual for details.
150 - The *.cmdline.[ch] files are no longer contained in the released
151 tarballs. This reduces the size of the tarballs but requires
152 gengetopt to build the tarball.
153 - Compiles cleanly also with llvm/clang.
154 - Corrupt mp3 files are handled more gracefully.
155 - The alsa writer uses poll fds instead of computing timeouts.
156 - Cleanup of the generic writer API.
157 - sched: Optimized zero timeouts.
158 - vss timeout cleanups.
159 - oggdec fixes and improvements.
161 --------------------------------------
162 0.4.7 (2011-06-01) "infinite rollback"
163 --------------------------------------
165 The new ao writer, support for ssh RSA keys and a couple of other
168 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
169 platforms through the libao audio library.
170 - Support for RSA keys generated with ssh-keygen.
171 - configure: improved options for ogg/vorbis/speex.
172 - The git version reported by --version always matches HEAD.
173 - The autogen script detects the number of processors and
174 runs a parallel make if possible.
175 - Major cleanup of the crypto API.
176 - Documentation updates.
178 ------------------------------------------
179 0.4.6 (2011-03-31) "deterministic entropy"
180 ------------------------------------------
182 Lots of ogg/vorbis improvements, the new test suite, enhancements
183 for para_gui and a fair amount of other bug fixes.
185 - For DCCP/OGG streams the audio file header is only sent once
186 at the beginning of the stream rather than periodically
187 every five seconds. This reduces network traffic and the
189 - The vorbis comment header is replaced by an empty dummy header
190 before the header is sent over the network. This also results in
191 less network traffic and smaller FEC groups.
192 - The new "test" make target allows to perform some sanity checks prior
193 to installing the package.
194 - ogg timing fixes and performance improvements
195 - Scheduler improvements
196 - Proper exit codes for para_write
197 - para_gui: New option --theme to select a startup theme. Several
198 other improvements and fixes.
199 - aacdec error message cleanups
200 - simplified color error handling
202 --------------------------------------------
203 0.4.5 (2010-12-17) "symmetric randomization"
204 --------------------------------------------
206 Bug fixes, internal cleanups and variable-sized FEC slices.
208 - Contains a fix for an invalid-free-bug in the ogg audio format
210 - Switching off the DCCP sender works again.
211 - para_audiod handles crashes of para_server more robustly.
212 - Internal scheduler and writer cleanups.
213 - Reduced latency due to variable-sized FEC slices.
214 - Improved documentation and error diagnostics.
215 - The build of para_server is now optional, allowing the build
216 to succeed in case libosl is not installed.
218 ------------------------------------------
219 0.4.4 (2010-08-06) "persistent regularity"
220 ------------------------------------------
222 Support for yet another audio format, para_write improvements and
225 - Support for the speex codec.
226 - Support for sample formats other than 16 bit little endian.
227 - error2.h is now created by a perl script which speeds up configure
229 - Fix a bug in the aac decoder which could lead to segfaults in
230 para_filter/para_audiod.
231 - Fixes for autoconf-2.66.
233 ----------------------------------------
234 0.4.3 (2010-07-05) "imaginary radiation"
235 ----------------------------------------
237 Many improvements for the DCCP and the UDP transport, the new user
238 manual and the usual mix of bug fixes and internal improvements.
240 - FEC support for the DCCP sender (Gerrit Renker). The new
241 --dccp_max_slice_size, --dccp_data_slices_per_group and
242 --dccp_slices_per_group options can be used to set the FEC
243 parameters for the DCCP transport.
244 - DNS lookups for UDP targets (Gerrit Renker).
245 - The new user manual replaces the README, README.afs, REQUIREMENTS
246 and INSTALL documents.
247 - Fix an end-of-file detection bug in the oggdec filter.
248 - The new nonblock API.
249 - Both options of the oggdec filter have been removed.
250 - New debug mode for the internal scheduler.
252 ------------------------------------------
253 0.4.2 (2010-04-23) "associative expansion"
254 ------------------------------------------
256 It's been some time since the last release, but finally here is
257 paraslash-0.4.2. The bulk of the changes comes from the new buffer
258 tree API, but there are changes all over the tree. Mainly performance
259 and usability improvements, but also quite some bug fixes.
261 - The new buffer tree API.
262 - DCCP: Support for CCID negotiation (Gerrit Renker).
263 - UDP robustness fixes.
264 - The --bufsize option for mp3dec is gone as it no longer makes sense
265 for the new buffer tree API.
266 - Fix audible buffer underruns for wma streams.
267 - The alsa writer no longer prints meaningless underrun durations.
268 - audiod: Defaults work also for udp streams. If no filter is
269 given for an audio format that is received via upd, fecdec is
270 automatically added as the first filter (along with the decoder).
272 ---------------------------------------
273 0.4.1 (2009-12-22) "concurrent horizon"
274 ---------------------------------------
276 Support for another audio format, minor feature enhancements and lots of bug
277 fixes. All fixes that have been accumulated in the maint branch (in particular
278 those mentionened in the 0.3.6 release notes) appear in this release as well.
281 - new afh option: --human to activate human-readable output.
282 - new server/audiod option: --log-timing to print timing information.
283 - build system improvements.
284 - source code documentation updates.
286 -------------------------------------
287 0.3.6 (2009-12-07) "cubic continuity"
288 -------------------------------------
290 Quite a few bugs have been found and fixed since 0.3.5, so here's
291 another 0.3.x release. No new features.
293 - Always check return value of malloc().
294 - ogg vorbis/FEC: Do not write garbage after the audio file header.
295 - exit if root privileges could not be dropped.
296 - FEC: Fix computation of extra slices.
297 - oss: Fix check for empty input buffer.
298 - Avoid buffer underruns due to filter chain output buffer constraints.
299 - server: Fix assignment of afs_pid.
300 - Don't panic if the afs database contains unknown audio formats.
301 - http/dccp: Do not send the audio file header twice.
302 - FEC: Timing improvements.
304 ----------------------------------------------
305 0.4.0 (2009-11-10) "simultaneous independence"
306 ----------------------------------------------
308 Two significant changes which require the new version number: The
309 improved authentication dialog and the fact that the database code
310 has been moved to a library, libosl. To use the new version, you have
311 to generate new RSA keys, see INSTALL for details. A shell script is
312 provided for conversion of the 0.3 database to the new 0.4 format.
314 - stronger crypto for client authentication
315 - the database code has been moved to a library
316 - improved status item handling
317 - cleanup of the build system
318 - The "-V" option now also prints the git version
319 - the new parser-friendly listing mode for the ls and stat commands
320 - mandatory rc4 encryption
321 - major audio format handler cleanups
322 - (id3,...) tags are no longer stored as a combined string in the database
323 - new mood methods: artist_matches, title_matches, comment_matches,
324 album_matches, year_maches, year.
326 --------------------------------------------
327 0.3.5 (2009-09-21) "symplectic separability"
328 --------------------------------------------
330 Full client support for *BSD Unixes, complete re-write of the ogg
331 vorbis audio format handler, various improvements all over the place
332 and the usual mix of bugfixes. This release marks the end of the 0.3
333 series if no serious problems show up.
335 - the new oss writer (supported on *BSD and Linux)
336 - rewrite of the ogg vorbis audio format handler. It's
337 recommended to replace the chunk tables of existing ogg
338 vorbis files in the afs database by re-adding these files
340 - support for netmask subsets (Gerrit Renker)
341 - the new prebuffer filter
342 - improved signal handling
343 - variable fec output buffer size
344 - improved FEC timing fixes audible buffer underruns in UDP mode
345 - --log_color actually works
346 - new ls option: -d (print dates as seconds after the epoch)
347 - update to gengetopt 2.22.2
348 - support for RSA keys of size > 512 bits
349 - new option "mixer_channel" for para_fade
351 -----------------------------------------
352 0.3.4 (2009-05-07) "elliptic inheritance"
353 -----------------------------------------
355 The new udp sender, forward error correction, colored logs and various
356 other improvements. As the udp sender does not depend on any special
357 libraries, it is built unconditionally.
359 - The udp sender replaces the ortp sender. The new code uses forward
360 error correction to protect against packet losses. Many thanks to
361 Gerrit Renker for providing ipv6 support.
362 - The default port for udp streaming now defaults to 8000, like
363 for the http and the dccp senders/receivers.
364 - Loglevels are now specified as symbolic names, e.g.
366 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
367 - para_server/para_audiod: Color support for log messages.
368 - new options for mp3dec: --ignore-crc, --bufsize
369 - new audiod option: --config-file.
370 - gengetopt cleanups.
371 - Improved help/man pages: The documentation of para_audiod,
372 para_recv, para_filter and para_write now also contains
373 all options of the available receivers/filters/writers. The
374 man page of para_fade contains a description of the different
376 - More source code documentation.
379 --------------------------------------------
380 0.3.3 (2008-12-01) "axiomatic perspectivity"
381 --------------------------------------------
383 Internal code cleanups, bug fixes, improved tag handling and the new
384 amplification filter.
386 - para_server uses the generic scheduling code.
387 - overhaul of the virtual streaming system.
388 - mp3: id3 version 2 support via libid3tag (optional)
389 - ogg: vorbis comment support.
390 - aac meta info support.
391 - mp3 audio format handler cleanups.
392 - new filter: "amp" to amplify the amplitude of the audio stream
393 - new status item/database entry: amplification. It is
394 used by the amp filter to pre-amplify the audio stream.
395 - fix a close-without-open bug in para_write.
396 - fix a bug in com_init() which was introduced in 0.3.2.
397 - better error diagnostics for para_client.
399 -----------------------------------------
400 0.3.2 (2008-04-11) "probabilistic parity"
401 -----------------------------------------
403 The new para_afh executable, scheduling and documentation improvements.
405 - new ls option: -lc (list chunk table)
406 - new executable: para_afh, the stand-alone audio file handler tool
407 - afs commands can send output more than SHMMAX (32MB on Linux). This
408 also reduces the memory usage of commands that produce large amounts
410 - major scheduler and audiod cleanups.
411 - more detailed and much nicer man pages.
413 ---------------------------------------
414 0.3.1 (2008-02-23) "liquid interaction"
415 ---------------------------------------
417 A mix of cleanups, bug fixes, improvements, and some new features. No
418 significant changes to the new database (osl) code, which is generally
421 - Share some similar/duplicate code between the http and the
423 - Generic access control lists for paraslash senders.
424 - dccp sender: Access control lists, connection limiting and support
425 for the allow,deny,on,off,help sender commands.
426 - The default dccp port changed from 5001 to 8000 (suggested by
428 - para_server starts even if not all public keys could be loaded.
429 - Audiod performance improvements.
430 - fix a bug in the "off" command of the http sender.
431 - fix some fd and memory leaks.
432 - Update to gengetopt-2.22.
434 -------------------------------------
435 0.3.0 (2008-01-12) "solar saturation"
436 -------------------------------------
438 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
441 Usually one might expect lots of new features AND a big increase in size
442 for a major release like this.
444 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
445 ever. The decrease in size is mostly due to the removal of some
446 graphical tools (which were only quick hacks anyway). But also the
447 fact that the mysql code is gone cuts down the size a bit.
449 Being independent of mysql comes at a cost: The fact that paraslash
450 now contains its own database (the object storage layer, osl) increases
451 the (stripped) binary size of para_server by ~50K on i386.
453 - no more restrictions on unique basenames.
454 - independent of mysql: The new self-contained object
455 storage layer (osl) replaces the mysql database.
456 - New executable para_fsck: Check integrity of osl tables.
458 - Reliable audio file move/rename detection.
459 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
460 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
462 - the new osl-based audio file selector (afs) replaces the random,
463 the playlist and the mysql selector of paraslash-0.2.x.
464 - IPv6 support (thanks to Gerrit Renker).
465 - paraslash-0.2.x streams are now called "moods". Writing
466 0.3.x-mood definitions should be both easier and more
467 powerful than writing 0.2.x-stream definitions.
468 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
469 been removed. The world is a better place without them. However,
470 para_gui is still there.
471 - afs tracks audio file selection also in playlist mode.
472 - few easy-to-use afs commands replace the many not-so-easy-to-use
473 mysql commands (and are available also in playlist mode).
474 - Improved error subsystem.
475 - The earth-shaking new logo.
477 -----------------------------------------
478 0.2.17 (2007-11-20) "isotropic threshold"
479 -----------------------------------------
481 Mainly bugfixes and cleanups in this version which marks the end of
482 the 0.2.x series if no serious bugs show up after the release.
484 - mysql_selector: fix a locking bug.
485 - universal chunk queueing.
486 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
488 - be more carful wrt. signed vs. unsigned argument passing.
489 - cleanup error.h and fix some references to invalid error
491 - update to gengetopt-2.21.
492 - update to ortp-0.13.1.
493 - autoconf: extend checks for headers, library functions and
494 compiler characteristics.
495 - Fix streaming of large mp3 files.
496 - Fix an off-by-one bug in playlist handling.
498 --------------------------------------
499 0.2.16 (2007-04-05) "neural discharge"
500 --------------------------------------
502 The main change in this release is the major audio format handler
503 cleanup which removes some similar/duplicate code and makes it easier
504 to implement plugins for other audio formats. Of course, the usual mix
505 of other improvements/changes/bugfixes also made it into the release.
507 - simplified audio format handlers (most of the handling functions
508 were moved one layer up to the virtual streaming system).
509 - para_server uses mmap to read audio files
510 - repositioning of mp3 streams is much faster, in particular for
511 jumping near the end of large mp3 files.
512 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
514 - fix a bug in para_filter that caused decoding of aac files
515 to start only after a few seconds.
516 - fix osx_writer hangs
517 - simplified dccp code (thanks to Gerrit Renker)
518 - the compress filter works also on big endian systems (ppc)
520 -----------------------------------------
521 0.2.15 (2007-02-16) "inductive resonance"
522 -----------------------------------------
524 Minor improvements, more documentation and a bunch of bug fixes.
526 - para_server: The server.users file is only read once on server
527 startup rather than for each connection
528 - mp3dec: Fix decoding of corrupt mp3 files
529 - afs (audio file sender) is now called vss (virtual streaming
530 system). Consequently, the permission flags specified in
531 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
532 become VSS_READ and VSS_WRITE respectively.
533 - para_audiod/para_filter: Fix a bug that caused the last chunk
534 of audio data not being written under certain circumstances
535 - audiod: compute the difference of server time and local time
537 - para_server/para_audiod: Fix some memory leaks
538 - documentation improvements
539 - configure.ac: fix checks for para_krell
542 -------------------------------------------
543 0.2.14 (2006-10-15) "transient singularity"
544 -------------------------------------------
546 The only major enhancement of this version is the osx writer which completes
547 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
548 until now for reasons beyond the scope of this changelog entry.
550 - new output plugin for Mac Os: the osx writer
551 - rename configure command line options from --enable-xxx-headers to
552 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
553 - configure: new command line options: --with-mad-headers,
554 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
555 - some robustness fixes
556 - dymamic audio format recognition for audiod
557 - para_server: new command line option: --autoplay_delay
558 - para_audiod: new command line option: --clock_diff_count
560 ---------------------------------------
561 0.2.13 (2006-07-14) "sonic convolution"
562 ---------------------------------------
564 A bunch of new features and core changes.
566 - the new paraslash scheduler, short and sweet.
567 - Support for m4a/mp4 files via the new aac audio format
568 handler/filter (requires libfaad).
569 - each writer has its own command line parser, just like
570 para_recv and para_filter.
571 - para_client and para_audioc use the error subsystem
572 - writers are integrated in para_audiod (currently linux-only)
573 - para_client is integrated in para_audiod
574 - random/playlist selector: improved info strings
575 - new audiod commands: tasks, kill
576 - update to libortp-0.10.1
577 - para_fade: wake time defaults to 8 hours from now
578 - update to autoconf-2.60
580 ------------------------------------------
581 0.2.12 (2006-05-12) "oriented abstraction"
582 ------------------------------------------
584 Many user-visible changes in this release and lots of new
588 - the new optional dccp sender/receiver. It uses the datagram
589 congestion control protocol. You'll need a fairly new kernel
591 - paraslash works on Mac OS X (thanks to Gerd Becker)
592 - para_play renamed to para_write
593 - modular output plugin design (writers) for para_write
594 - new file_writer output plugin for para_write
595 - compress filter speed improvements
596 - update to libortp-0.9.1
597 - update to gengetopt-2.17rc
598 - para_client no longer depends on libreadline (as the
599 code for the interactive mode was removed).
600 - gcc-2-95 is no longer a supported compiler. It may still
601 work, but it gets no more testing.
602 - the tarball no longer contains the screenshot images which
603 reduces its size quite a bit.
604 - configure: new command line options: --enable-mysql-headers
605 and --enable-mysql-libs
607 ------------------------------------
608 0.2.11 (2006-03-11) "atomic duality"
609 ------------------------------------
611 Here it is, the first paraslash release developed with git. There
612 are fairly many user-visible changes in this release. As two out of
613 the three "database tools" of paraslash don't use a database at all,
614 they are now called "audio file selectors" instead.
617 - the cdt command (change database tool) becomes chs (change
619 - no more colon separators: The syntax of some options of
620 para_audiod and para_filter have changed. Use --help for
621 more info (and some examples).
622 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
623 - switch from cvs to git (should've done that earlier)
624 - the new ipc subsystem
625 - new audio file selector: playlist
626 - para_server: the dopey selector is now called "random",
627 and is the default selector. Use the --selector option to
628 choose another selector at startup, or the chs command to
629 change the selector at runtime.
630 - X86_64 fixes (thanks to Steffen Klassert)
633 --------------------------------------
634 0.2.10 (2006-02-17) "cyclic attractor"
635 --------------------------------------
637 Huge documentation update, a scrollable window for para_gui, ortp
638 improvements, and of course many small fixes not mentioned here.
639 The diffstat below is rather misleading as most insertions are due
640 to the new source documentation.
643 - para_server also uses the new error subsystem
644 - lots of new documentation (UTSL)
646 - keysyms for cursor keys and for next/previous page keys
647 - scrollable output window
648 - new internal commands: scroll up/down, page up/down
649 - fix color of command output.
650 - ortp: the --chunk_time and --header flags are no longer needed
651 for para_recv/para_audiod as this information is now encoded in
652 each rtp packet sent by para_server.
654 -------------------------------------------
655 0.2.9 (2006-01-24) "progressive turbulence"
656 -------------------------------------------
658 Internal audiod receivers/filters, the new error subsystem and
659 a lot of small improvements.
661 - para_recv and para_filter are integrated into the para_audiod
662 binary, i.e. audiod no longer spawns a new process for
663 each receiver/filter. As para_recv and para_filter might be
664 useful as standalone programs, they still get built (linked
665 against the same object files that are also used for audiod).
666 - further ortp timing improvements should reduce the CPU usage
667 of the ortp receiver.
668 - improved audio grabbing. The 'grab' command of para_audiod
669 has its own set of command line options. Read the output of
670 "para_audioc help grab" for more info.
671 - oggdec: configurable input prebuffer size.
672 - the new error subsystem gives better error diagnostics
673 and reduces code size.
675 -----------------------------------------
676 0.2.8 (2006-01-02) "dynamic accumulation"
677 -----------------------------------------
679 The new modular filter design and the para_play-hangs bugfix.
681 - new executable: para_filter. It combines para_mp3dec,
682 para_oggdec and para_compress. It also adds a further filter
683 type, wav, that just inserts a wave header at the desired point
684 of the filter chain. All 'piping' is done in-memory (i.e. no
685 read/write operations are used).
686 - para_play: fix a stupid bug that caused it to hang under
687 certain circumstances.
689 -------------------------------------------
690 0.2.7 (2006-12-27) "transparent invariance"
691 -------------------------------------------
693 Not many user-visible changes but a fair amount of internal improvements.
696 - The http sender buffers data if it can not be sent
697 out immediately (because the socket is not writable). This
698 should prevent para_server from shutting down the connection
699 too early on a loaded network.
700 - para_play also prebuffers data if it is told to start at a
701 future time by the --start_time option.
702 - The return of para_recv: It combines para_ortp_recv and
703 para_http_recv. Use the --receiver option to switch between
704 the two. para_recv builds without libortp, but contains
705 only the http receiver in this case.
706 - update to ortp 0.8.1. As this ortp release contains incompatible
707 changes, para_recv-0.2.7 won't link against older ortp libs.
708 - improved ortp timings.
709 - use of gcc-extensions that #define away for non-gcc and
712 -------------------------------------------
713 0.2.6 (2005-10-29) "recursive compensation"
714 -------------------------------------------
716 Transparent session encryption (uses openssl's Alleged RC4 cipher),
717 the internal find command and several other improvements and cleanups.
719 - Encrypt the session if encryption is requested by the client
720 (default for para_client 0.2.6). This is backwards
721 compatible, so older clients can still connect to para_server
722 0.2.6. Use the new client option --plain to request an
723 uncrypted session (off by default, must be set to on in
724 order to connect to para_server 0.2.x with 0 <= x <= 5).
725 - para_server uses an internal function to locate audio files
726 rather than calling find(1). The server option
727 --mysql_audio_file_dir replaces --mysql_find_cmd.
728 - documentation update
730 - header file cleanup
731 - para_client code cleanup
732 - para_gui: faster display of output of display commands
734 ------------------------------------------
735 0.2.5 (2005-10-13) "aggressive resolution"
736 ------------------------------------------
738 This release adds internal senders, i.e. no more external programs are
739 spawned for sending out the audio data. There are two different senders
740 available: The http sender and the ortp sender (former para_send which
741 is no longer needed).
743 The new sender code has a plugin-like design so it can be easily
744 extended should there be be any future need for supporting another
745 network streaming protocol. All senders are completely independent of
746 each other. In particular, the http and the ortp sender can operate
749 - new server command: sender to control senders at runtime.
750 Read the output of "para_server -h" and "para_client help
751 sender" for more information.
752 - para_recv renamed to para_ortp_recv
753 - new executable: para_http_recv, a simple command line
755 - major afs/mp3/ogg code simplifications due to internal
757 - ogg timing improvements
758 - fix several minor memory leaks (found by valgrind)
759 - empty stream definitions work again
760 - com_ne(): ignore errors on remove
761 - audiod: fix segfault on server restart
763 ---------------------------------------
764 0.2.4 (2005-09-21) "toxic anticipation"
765 ---------------------------------------
767 Several small improvements, fixes and the new grab command.
770 - new command: "grab" to grab the output of the stream reader
771 or any filters. Read the output of "para_audioc help grab"
772 for more information.
775 - audioc: new command line option: --bufsize to specify a
776 buffer size different from the default size 8192.
777 - improved error diagnostics for para_play.
778 - new configure option: --enable-ssldir so search for openssl in
780 - sdl_gui: Make it look nice again for 1024x768
781 - server: report total size of memory allocated with sbrk by malloc,
782 new command line option: --announce_time
784 -----------------------------------------
785 0.2.3 (2005-09-01) "hydrophilic movement"
786 -----------------------------------------
788 Two new executables and major feature enhancements.
790 - audiod filters: It is now possible to specify arbitrary many
791 (including none) filters for each supported audio
792 format. This can be used e.g. for normalizing volume,
793 transforming or grabbing the audio stream, or for using
794 visualizers. Read the output of "para_audiod -h" for the
795 syntax of the new --filter_cmd option.
796 - new executable: para_play, a tiny alsa player. It
797 can play wave files or raw pcm (16 bit little endian)
799 - new executable: para_compress, a dynamic range compressor
800 intended to keep audio output at a consistent volume. Derived
801 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
802 - audiod: New option: --stream_delay. This can be used in
803 a local network to syncronize the audio output of all
804 clients that play the same stream.
806 ------------------------------------------
807 0.2.2 (2005-08-19) "tangential excitation"
808 ------------------------------------------
810 Mostly internal changes in this release, but also some new commands
811 for the mysql database tool.
813 - cleanup exec.c, fix para_exec bug
814 - compile time loglevel (log messages below the given level
815 won't be compiled in, which reduces the size of the
817 - new log macros that shorten the size of the source code.
818 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
819 to send only zeros. With this workaround, para_audioc works
821 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
822 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
823 (new entry), "snp" (set numplayed). Read the manual for more
826 ---------------------------------------
827 0.2.1 (2005-08-15) "surreal experience"
828 ---------------------------------------
830 Here comes paraslash-0.2.1. It contains a couple of new features and,
831 surprise, only minor bug fixes.
833 - kill noisy mp3 debug message
834 - cleanup of the build system
835 - para_server and para_client directly use the crypto routines
836 of the openssl library rather than invoking the openssl command
838 - server/audiod: new option --user to switch to the given user
839 when invoked as root. Read the output of "para_server -h" for
841 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
842 status. Default: "para_audioc stat"
843 - sdl_gui: new option --pic_cmd to be used to download the picture.
844 Default: "para_client pic"
845 - audiod: 5 slots ought to be enough for everybody
846 - audiod: new status item: Uptime, kill hup command
848 ------------------------------------------
849 0.2.0 (2005-08-06) "distributed diffusion"
850 ------------------------------------------
852 After several month of increased development activity, paraslash-0.2.0
853 has arrived. It contains many new features and is much more
854 self-contained than the old 0.1.x series. Enjoy!
857 - para_server: fix hang on song change and crash on sighup.
858 Speed up mysql queries. The DIR_LIKE macro is gone.
859 - new executables: para_audiod, the local audio daemon that
860 starts playback (uses SCM_CREDENTIALS socket magic) and
861 para_audioc, the corresponding client.
862 - new executables: para_mp3dec/para_oggdec, two really teensy
863 decoders. para_mp3dec is based on libmad, para_oggdec requires
865 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
866 they are now called para_send and para_recv respectively.
867 - documentation updates
868 - para_gui is themable. For now there is the default theme that
869 looks as before and the simple theme: blue and easy.
870 - gui: audio streaming is now handled by audiod. Time display shows
871 playback time rather than streaming time
872 - slider: update to libzmw-0.2.0
873 - para_krell: fix crash on server shutdown
874 - switch from gzip to bzip2
876 ----------------------------------------
877 0.1.7 (2005-04-18) "melting penetration"
878 ----------------------------------------
880 The main change in this release is clearly the oggvorbis rewrite,
881 but there are also lots of smaller changes. If you intend to use both
882 the mp3 and the ogg plugin, it is recommended to use software mixing,
883 e.g. the dmix plugin which is provided by ALSA.
885 - new executables: para_ovsend and para_ovrecv for sending/receiving
886 oggvorbis files via rtp. Requires the open rtp library. Get it at
887 http://www.linphone.org/ortp/
888 - rewrite of the ogg_vorbis core code
889 - configure detects libzmw and, if detected, includes
890 para_slider to the list of binaries to be built by make
891 - server stream writers read from their associated fifo rather
893 - slider: two new sliders, lastplayed and numplayed
894 - fix nasty double free bug which caused random segfaults in case of
895 mp3 files with invalid header information
896 - gui: new command line option: --stream_timeout=seconds to
897 deactivate a slot if it is idle for that many seconds (default=`5')
900 ---------------------------------------
901 0.1.6 (2005-03-05) "asymptotic balance"
902 ---------------------------------------
904 Only little user-visible changes in this release. Mainly bugfixes and
905 core code cleanup. This is probably the most stable version ever if you
908 - fix several memory leaks
909 - rename default name of mysql database from "music" to "paraslash".
910 Use para_server's --mysql_database option if you do not want to
911 rename your old database.
912 - rework ogg vorbis code
913 - make update command work on mysql servers with LOCAL_INFILE
915 - gui: improved stream I/O (slots)
916 - simplified audio format API
917 - para_pob_ogg is gone
919 ------------------------------------
920 0.1.5 (2004-12-31) "opaque eternity"
921 ------------------------------------
923 Let's slide gently into the new year.
925 - new: para_slider (not built automatically, type "make
926 para_slider" to build). A toy for those who always felt that
927 creating stream definitions is difficult. See screenshots,
928 README and FEATURES for more info.
929 - improved signal handling. Fixes server segfault on SIGHUP
930 for linux kernels newer than Aug 24 2004 and makes para_gui
932 - reload database tool on SIGHUP
933 - improved help message for sl
934 - do not log "broken pipe" messages as errors. They are
936 - fix wrong error message on permission errors
938 -----------------------------------------
939 0.1.4 (2004-12-19) "tunneling transition"
940 -----------------------------------------
942 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
943 Hopefully, most of them got wiped out with this release. Some
944 enhancements went also in.
946 - improved error diagnostics for all commands
947 - stradd/picadd: overwrite previous contents if entry already
948 exists, rather than returning errors
949 - stradd: use current stream if invoked without args
950 - faster (and hopefully more stable) ogg-vorbis handling
951 - para_krell: reap children to avoid zombie-flooding in case
953 - si: report also server pid
954 - server: don't busy-loop if dbtool reports only invalid files.
955 - gui: CTRL+C works again, fix stream_read command line option
957 - fix mysql dbtool startup in case no database exists
958 - many small fixes and cleanups
960 ---------------------------------------
961 0.1.3: (2004-12-10) "vanishing inertia"
962 ---------------------------------------
964 Starting from this release, the database tools are integrated in the
965 server binary. This decreases server startup time, reduces code size
966 and speeds up database commands. However, the layout of the underlying
967 mysql database changed only slightly and 0.1.3 should be backwards
968 compatible in that respect.
972 - If mysql is not detected at compile time, or fails to init
973 at runtime, fall back to the dopey database tool which should
975 - para_dbtool and dbtool.conf are gone. All mysql specific
976 options are read from server.conf and are prefixed by 'mysql_'.
977 - new command: cdt (change database tool)
978 - new command line option: dbtool (choose startup database tool)
979 - The name of current stream is now stored in the database,
980 so paraslash remembers its current stream when restarted.
981 - new command: csp (change stream and play)
982 - para_gui also reports current database tool and server uptime
984 -------------------------------------------
985 0.1.2: (2004-11-28) "spherical fluctuation"
986 -------------------------------------------
988 Point release before the big dbtool changes go in.
990 - dbtool: rename ca to cam (copy all meta data). It now also
991 copies numplayed and lastplayed time as well as the picture
993 - fix endless-loop-bug caused by mp3 files with invalid header
995 -----------------------------------------
996 0.1.1: (2004-11-05) "floating atmosphere"
997 -----------------------------------------
1000 - new dbtool command: mbox. Browse your sound-file collection
1001 with your favorite mail reader.
1002 - several small fixes
1004 -------------------------------------
1005 0.1.0: (2004-10-22) "rotating cortex"
1006 -------------------------------------
1008 - fix logging bug for loglevel > VERBOSE
1010 - correct timings for vbr mp3s
1011 - modular audio format support
1012 - ogg-vorbis support (experimental)
1013 - new server option: autoplay
1015 -----------------------------------------
1016 0.0.99: (2004-07-25) "harmonic deviation"
1017 -----------------------------------------
1019 - rename projectname from icc to paraslash (play, archive, rate
1020 and stream large audio sets happily)
1021 - paraslash is no longer restricted to one particular audio
1023 - new dbtool commands (stradd, strq, strdel) for easy stream
1024 managment w/o configuration file. That obsoletes stream_defs
1025 file/config option for dbtool.
1026 - picadd accepts jpeg data from stdin
1027 - new server commands: ps (select previous stream), sc (song change)
1028 - new default pictures for sdl_gui
1029 - gui: new key_map option for binding commands and internal
1030 functions to arbitrary keys, nice help screen, rip out
1031 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1032 show silly logo on startup
1033 - new executables: para_fade for fading volume, para_dbadm for
1034 manipulating attributes
1035 - cdb adds _all_ tables to mysql database
1036 - revised and beautified documentation
1037 - sample dbtool rewritten in C
1040 ---------------------------------------------
1041 0.0.98: (2003-12-26) "incremental smoothness"
1042 ---------------------------------------------
1044 - kick icecast in favour of poc. That removes some races and reduces
1045 core code considerably.
1046 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1047 give finer info on afs' status.
1048 - gui can start decoder (see config options). Further new gui
1049 commands: refresh (^L), jmp (F1-F10)
1050 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1051 terminates gui. This fixes dead instances consuming memory
1053 - new dbtool command: verb for sending verbatim sql queries.
1054 - fix pid_list races (by removing pid_list)
1057 --------------------
1058 0.0.97: (2003-10-26)
1059 --------------------
1061 - installation prefix now defaults to /usr/local
1062 - new commands for gui: snozze, sleep and reread config
1063 - config file for gui and sdl_gui
1064 - fix problems with filenames containing funny characters
1065 (reported by Thomas Forell)
1066 - improved signal handling for gui, now it rereads conf on SIGHUP
1067 - new dbtool command: cdb (create database)
1068 - switch from argtable to gengetopt
1069 - major code cleanup and speed improvements
1070 - fix several potential buffer overflows
1071 - many small fixes and cleanups
1077 - easy stream_defs syntax
1078 - sdl_gui can display images associated to the file being played
1079 - Major feature enhancements for icc_gui including dynamic text
1080 placement and the top/bottom window design
1081 - vrfy/clean now also checks for NULL values in attributes as
1082 well as for invalid picture pointers
1083 - fix long outstanding case sensitivity bug
1084 - many small fixes and cleanups
1090 - sdl gui runs much faster
1091 - new dbtool command: ca (copy attributes)
1092 - count and display number of times the song has been played
1093 - new feature: scoring
1094 - command line options for sdl_gui
1095 - simpler syntax of streams file
1096 - decrease network traffic of stat
1098 - many small fixes and cleanups
1104 - new server command: ns (next stream)
1105 - new icc_gui command: c (change stream)
1107 - stat shows also id3 tag info
1109 - log flodding bug fixed
1110 - many small fixes and cleanups
1116 - colors for icc_gui
1117 - icc_gui sets volume directly (linux only)
1118 - proper locking that fixes some races
1119 - fix security bug that caused commands to be executed even
1120 with unsufficient permissions
1121 - new command: hup to make all servers reread their configuration file
1122 - icecast meta data streaming
1123 - many small fixes and cleanups
