1 --------------------------------------
2 0.4.13 (2013-07-29) "spectral gravity"
3 --------------------------------------
5 One more 0.4.x release before the API-breaking changes for 0.5.0 go
6 in. The main features of this release are the ogg/opus audio format,
7 and UTF-8 support, but it includes also tons of other improvements
8 and fixes all over the place.
10 - New audio format: ogg/opus.
11 - UTF8 support for para_gui and the mp3 audio format handler.
12 - Scheduler improvements and fixes.
13 - The obsolete gettimeofday() function has been replaced
14 by clock_gettime() on systems which support it.
15 - Speed and usability improvements for para_gui.
16 - para_client now restores the fd flags of stdin and stdout
18 - Improved manual pages.
19 - Consistent version strings for all executables.
20 - Reduced depencies on generated files result in fewer
21 recompilations on changes.
22 - Performance improvements for the compress filter.
23 - Improved downloads web page.
25 -----------------------------------------
26 0.4.12 (2012-12-20) "volatile relativity"
27 -----------------------------------------
28 The new command line player, the resample filter, ALSA support for
29 para_fade, and the improved build system are the highlights of this
30 release which probably marks the end of the 0.4.x series.
32 - The afh receiver and the para_play executable.
33 - The resample filter: A sample rate converter based on
35 - The "versions" directory has been removed from the master
36 branch. The tarballs of the old releases are now available
37 in the new "releases" branch.
38 - Overhaul of the build system: All generated files are now
39 written to the "build" directory.
40 - The modular mixer API and the alsa mixer.
41 - Minor fixes for the osx writer.
43 --------------------------------------
44 0.4.11 (2012-07-20) "mutual diversity"
45 --------------------------------------
47 The major feature in this release is the new sideband API for
48 client-server communication. This API will be used exclusively starting
49 with 0.5.0, which breaks backward compatibility but allows to get rid
50 of quite some compatibility code. Other noteworthy changes include
51 decoder latency improvements and a long-standing bug fix for the
54 - Sideband connections: If both para_server and para_client
55 support this feature, data is sent as a multiplexed stream.
56 - The --no_default_filters option of para_filter has been
58 - Several fixes and latency improvements to various decoders.
59 - The ALSA writer now limits the prebuffer time to 500ms.
60 - Documentation improvements.
61 - Overhaul of the command_util.sh script.
62 - Fixes for some minor problems found by the clang analyzer.
63 - Compiles (almost) without warnings on gcc-3.
64 - Robustness improvements of the buffer tree code.
66 ------------------------------------------
67 0.4.10 (2012-03-30) "heterogeneous vacuum"
68 ------------------------------------------
70 Nothing earth-shaking in this release, but quite a few usability
71 improvements and the usual mix of cleanups and fixes.
73 - The --no_default_filters option of para_filter has been
74 deprecated. It still works but has no effect and will be
75 removed in the next version.
76 - para_gui now prints also the stderr output of the executing
77 command in the bottom window.
78 - Cleanup and consolidation of the various wrappers for
79 write(), writev(), send() and friends.
80 - The obscure error messages on mmap() failures have been
81 replaced by meaningful messages. This affects mainly
83 - para_audioc: Cleanups and memory leak fixes.
84 - Test 0004-server no longer fails if para_server is not
86 - New configure options: --with-id3tag-{headers,libs}.
88 -------------------------------------
89 0.4.9 (2011-12-06) "hybrid causality"
90 -------------------------------------
92 Support for another audio format, interactive mode for para_client
93 and para_audiod and many small improvements/fixes all over the place.
95 - Support for flac, the free lossless audio codec.
96 - Fix for an endless loop in the mp3 decoder for certain
98 - When executed without specifying a command, para_client
99 and para_audioc start an interactive shell (requires
100 libreadline being installed). The interactive mode offers
101 full tab completion and command line history.
102 - autogen.sh now detects a distcc setup and adjusts the
103 parameter for the -j option of make accordingly.
104 - Shared memory areas are no longer restricted to 64K. We now
105 detect the maximal size of a shared memory area at runtime.
106 - cleanup of the internal uptime API.
107 - para_server prefaults the mmapped audio file to avoid
108 delays on slow media.
109 - A new test for the test-suite that exercises the
110 communication between para_server and para_audiod.
111 - The alsa writer eats up less CPU cycles when configured to
113 - Simplified and unified receiver code.
115 - Commands which print a list of matching audio files now
116 emit a meaningful error message if no audio file matched the
119 --------------------------------------
120 0.4.8 (2011-08-19) "nested assignment"
121 --------------------------------------
123 Gcrypt support, the overhauled osx writer and regex format specifiers
124 are the highlights of this release.
126 - support for libgcrypt as a drop-in replacement for openssl.
127 Run configure --enable-cryptolib=gcrypt to link against
128 libgcrypt. The two crypto implementations are compatible to
129 each other, i.e. a para_client executable linked against
130 gcrypt can connect to para_server linked against libssl
132 - Rewrite of the osx writer (output plugin for Mac OS).
133 - audiod: The format specifier for receivers, filters and
134 writers is now treated as a regular expression. This allows
135 to replace 5 lines in the config file (one for each audio
136 format) by one single line. See the manual for details.
137 - The *.cmdline.[ch] files are no longer contained in the released
138 tarballs. This reduces the size of the tarballs but requires
139 gengetopt to build the tarball.
140 - Compiles cleanly also with llvm/clang.
141 - Corrupt mp3 files are handled more gracefully.
142 - The alsa writer uses poll fds instead of computing timeouts.
143 - Cleanup of the generic writer API.
144 - sched: Optimized zero timeouts.
145 - vss timeout cleanups.
146 - oggdec fixes and improvements.
148 --------------------------------------
149 0.4.7 (2011-06-01) "infinite rollback"
150 --------------------------------------
152 The new ao writer, support for ssh RSA keys and a couple of other
155 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
156 platforms through the libao audio library.
157 - Support for RSA keys generated with ssh-keygen.
158 - configure: improved options for ogg/vorbis/speex.
159 - The git version reported by --version always matches HEAD.
160 - The autogen script detects the number of processors and
161 runs a parallel make if possible.
162 - Major cleanup of the crypto API.
163 - Documentation updates.
165 ------------------------------------------
166 0.4.6 (2011-03-31) "deterministic entropy"
167 ------------------------------------------
169 Lots of ogg/vorbis improvements, the new test suite, enhancements
170 for para_gui and a fair amount of other bug fixes.
172 - For DCCP/OGG streams the audio file header is only sent once
173 at the beginning of the stream rather than periodically
174 every five seconds. This reduces network traffic and the
176 - The vorbis comment header is replaced by an empty dummy header
177 before the header is sent over the network. This also results in
178 less network traffic and smaller FEC groups.
179 - The new "test" make target allows to perform some sanity checks prior
180 to installing the package.
181 - ogg timing fixes and performance improvements
182 - Scheduler improvements
183 - Proper exit codes for para_write
184 - para_gui: New option --theme to select a startup theme. Several
185 other improvements and fixes.
186 - aacdec error message cleanups
187 - simplified color error handling
189 --------------------------------------------
190 0.4.5 (2010-12-17) "symmetric randomization"
191 --------------------------------------------
193 Bug fixes, internal cleanups and variable-sized FEC slices.
195 - Contains a fix for an invalid-free-bug in the ogg audio format
197 - Switching off the DCCP sender works again.
198 - para_audiod handles crashes of para_server more robustly.
199 - Internal scheduler and writer cleanups.
200 - Reduced latency due to variable-sized FEC slices.
201 - Improved documentation and error diagnostics.
202 - The build of para_server is now optional, allowing the build
203 to succeed in case libosl is not installed.
205 ------------------------------------------
206 0.4.4 (2010-08-06) "persistent regularity"
207 ------------------------------------------
209 Support for yet another audio format, para_write improvements and
212 - Support for the speex codec.
213 - Support for sample formats other than 16 bit little endian.
214 - error2.h is now created by a perl script which speeds up configure
216 - Fix a bug in the aac decoder which could lead to segfaults in
217 para_filter/para_audiod.
218 - Fixes for autoconf-2.66.
220 ----------------------------------------
221 0.4.3 (2010-07-05) "imaginary radiation"
222 ----------------------------------------
224 Many improvements for the DCCP and the UDP transport, the new user
225 manual and the usual mix of bug fixes and internal improvements.
227 - FEC support for the DCCP sender (Gerrit Renker). The new
228 --dccp_max_slice_size, --dccp_data_slices_per_group and
229 --dccp_slices_per_group options can be used to set the FEC
230 parameters for the DCCP transport.
231 - DNS lookups for UDP targets (Gerrit Renker).
232 - The new user manual replaces the README, README.afs, REQUIREMENTS
233 and INSTALL documents.
234 - Fix an end-of-file detection bug in the oggdec filter.
235 - The new nonblock API.
236 - Both options of the oggdec filter have been removed.
237 - New debug mode for the internal scheduler.
239 ------------------------------------------
240 0.4.2 (2010-04-23) "associative expansion"
241 ------------------------------------------
243 It's been some time since the last release, but finally here is
244 paraslash-0.4.2. The bulk of the changes comes from the new buffer
245 tree API, but there are changes all over the tree. Mainly performance
246 and usability improvements, but also quite some bug fixes.
248 - The new buffer tree API.
249 - DCCP: Support for CCID negotiation (Gerrit Renker).
250 - UDP robustness fixes.
251 - The --bufsize option for mp3dec is gone as it no longer makes sense
252 for the new buffer tree API.
253 - Fix audible buffer underruns for wma streams.
254 - The alsa writer no longer prints meaningless underrun durations.
255 - audiod: Defaults work also for udp streams. If no filter is
256 given for an audio format that is received via upd, fecdec is
257 automatically added as the first filter (along with the decoder).
259 ---------------------------------------
260 0.4.1 (2009-12-22) "concurrent horizon"
261 ---------------------------------------
263 Support for another audio format, minor feature enhancements and lots of bug
264 fixes. All fixes that have been accumulated in the maint branch (in particular
265 those mentionened in the 0.3.6 release notes) appear in this release as well.
268 - new afh option: --human to activate human-readable output.
269 - new server/audiod option: --log-timing to print timing information.
270 - build system improvements.
271 - source code documentation updates.
273 -------------------------------------
274 0.3.6 (2009-12-07) "cubic continuity"
275 -------------------------------------
277 Quite a few bugs have been found and fixed since 0.3.5, so here's
278 another 0.3.x release. No new features.
280 - Always check return value of malloc().
281 - ogg vorbis/FEC: Do not write garbage after the audio file header.
282 - exit if root privileges could not be dropped.
283 - FEC: Fix computation of extra slices.
284 - oss: Fix check for empty input buffer.
285 - Avoid buffer underruns due to filter chain output buffer constraints.
286 - server: Fix assignment of afs_pid.
287 - Don't panic if the afs database contains unknown audio formats.
288 - http/dccp: Do not send the audio file header twice.
289 - FEC: Timing improvements.
291 ----------------------------------------------
292 0.4.0 (2009-11-10) "simultaneous independence"
293 ----------------------------------------------
295 Two significant changes which require the new version number: The
296 improved authentication dialog and the fact that the database code
297 has been moved to a library, libosl. To use the new version, you have
298 to generate new RSA keys, see INSTALL for details. A shell script is
299 provided for conversion of the 0.3 database to the new 0.4 format.
301 - stronger crypto for client authentication
302 - the database code has been moved to a library
303 - improved status item handling
304 - cleanup of the build system
305 - The "-V" option now also prints the git version
306 - the new parser-friendly listing mode for the ls and stat commands
307 - mandatory rc4 encryption
308 - major audio format handler cleanups
309 - (id3,...) tags are no longer stored as a combined string in the database
310 - new mood methods: artist_matches, title_matches, comment_matches,
311 album_matches, year_maches, year.
313 --------------------------------------------
314 0.3.5 (2009-09-21) "symplectic separability"
315 --------------------------------------------
317 Full client support for *BSD Unixes, complete re-write of the ogg
318 vorbis audio format handler, various improvements all over the place
319 and the usual mix of bugfixes. This release marks the end of the 0.3
320 series if no serious problems show up.
322 - the new oss writer (supported on *BSD and Linux)
323 - rewrite of the ogg vorbis audio format handler. It's
324 recommended to replace the chunk tables of existing ogg
325 vorbis files in the afs database by re-adding these files
327 - support for netmask subsets (Gerrit Renker)
328 - the new prebuffer filter
329 - improved signal handling
330 - variable fec output buffer size
331 - improved FEC timing fixes audible buffer underruns in UDP mode
332 - --log_color actually works
333 - new ls option: -d (print dates as seconds after the epoch)
334 - update to gengetopt 2.22.2
335 - support for RSA keys of size > 512 bits
336 - new option "mixer_channel" for para_fade
338 -----------------------------------------
339 0.3.4 (2009-05-07) "elliptic inheritance"
340 -----------------------------------------
342 The new udp sender, forward error correction, colored logs and various
343 other improvements. As the udp sender does not depend on any special
344 libraries, it is built unconditionally.
346 - The udp sender replaces the ortp sender. The new code uses forward
347 error correction to protect against packet losses. Many thanks to
348 Gerrit Renker for providing ipv6 support.
349 - The default port for udp streaming now defaults to 8000, like
350 for the http and the dccp senders/receivers.
351 - Loglevels are now specified as symbolic names, e.g.
353 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
354 - para_server/para_audiod: Color support for log messages.
355 - new options for mp3dec: --ignore-crc, --bufsize
356 - new audiod option: --config-file.
357 - gengetopt cleanups.
358 - Improved help/man pages: The documentation of para_audiod,
359 para_recv, para_filter and para_write now also contains
360 all options of the available receivers/filters/writers. The
361 man page of para_fade contains a description of the different
363 - More source code documentation.
366 --------------------------------------------
367 0.3.3 (2008-12-01) "axiomatic perspectivity"
368 --------------------------------------------
370 Internal code cleanups, bug fixes, improved tag handling and the new
371 amplification filter.
373 - para_server uses the generic scheduling code.
374 - overhaul of the virtual streaming system.
375 - mp3: id3 version 2 support via libid3tag (optional)
376 - ogg: vorbis comment support.
377 - aac meta info support.
378 - mp3 audio format handler cleanups.
379 - new filter: "amp" to amplify the amplitude of the audio stream
380 - new status item/database entry: amplification. It is
381 used by the amp filter to pre-amplify the audio stream.
382 - fix a close-without-open bug in para_write.
383 - fix a bug in com_init() which was introduced in 0.3.2.
384 - better error diagnostics for para_client.
386 -----------------------------------------
387 0.3.2 (2008-04-11) "probabilistic parity"
388 -----------------------------------------
390 The new para_afh executable, scheduling and documentation improvements.
392 - new ls option: -lc (list chunk table)
393 - new executable: para_afh, the stand-alone audio file handler tool
394 - afs commands can send output more than SHMMAX (32MB on Linux). This
395 also reduces the memory usage of commands that produce large amounts
397 - major scheduler and audiod cleanups.
398 - more detailed and much nicer man pages.
400 ---------------------------------------
401 0.3.1 (2008-02-23) "liquid interaction"
402 ---------------------------------------
404 A mix of cleanups, bug fixes, improvements, and some new features. No
405 significant changes to the new database (osl) code, which is generally
408 - Share some similar/duplicate code between the http and the
410 - Generic access control lists for paraslash senders.
411 - dccp sender: Access control lists, connection limiting and support
412 for the allow,deny,on,off,help sender commands.
413 - The default dccp port changed from 5001 to 8000 (suggested by
415 - para_server starts even if not all public keys could be loaded.
416 - Audiod performance improvements.
417 - fix a bug in the "off" command of the http sender.
418 - fix some fd and memory leaks.
419 - Update to gengetopt-2.22.
421 -------------------------------------
422 0.3.0 (2008-01-12) "solar saturation"
423 -------------------------------------
425 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
428 Usually one might expect lots of new features AND a big increase in size
429 for a major release like this.
431 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
432 ever. The decrease in size is mostly due to the removal of some
433 graphical tools (which were only quick hacks anyway). But also the
434 fact that the mysql code is gone cuts down the size a bit.
436 Being independent of mysql comes at a cost: The fact that paraslash
437 now contains its own database (the object storage layer, osl) increases
438 the (stripped) binary size of para_server by ~50K on i386.
440 - no more restrictions on unique basenames.
441 - independent of mysql: The new self-contained object
442 storage layer (osl) replaces the mysql database.
443 - New executable para_fsck: Check integrity of osl tables.
445 - Reliable audio file move/rename detection.
446 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
447 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
449 - the new osl-based audio file selector (afs) replaces the random,
450 the playlist and the mysql selector of paraslash-0.2.x.
451 - IPv6 support (thanks to Gerrit Renker).
452 - paraslash-0.2.x streams are now called "moods". Writing
453 0.3.x-mood definitions should be both easier and more
454 powerful than writing 0.2.x-stream definitions.
455 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
456 been removed. The world is a better place without them. However,
457 para_gui is still there.
458 - afs tracks audio file selection also in playlist mode.
459 - few easy-to-use afs commands replace the many not-so-easy-to-use
460 mysql commands (and are available also in playlist mode).
461 - Improved error subsystem.
462 - The earth-shaking new logo.
464 -----------------------------------------
465 0.2.17 (2007-11-20) "isotropic threshold"
466 -----------------------------------------
468 Mainly bugfixes and cleanups in this version which marks the end of
469 the 0.2.x series if no serious bugs show up after the release.
471 - mysql_selector: fix a locking bug.
472 - universal chunk queueing.
473 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
475 - be more carful wrt. signed vs. unsigned argument passing.
476 - cleanup error.h and fix some references to invalid error
478 - update to gengetopt-2.21.
479 - update to ortp-0.13.1.
480 - autoconf: extend checks for headers, library functions and
481 compiler characteristics.
482 - Fix streaming of large mp3 files.
483 - Fix an off-by-one bug in playlist handling.
485 --------------------------------------
486 0.2.16 (2007-04-05) "neural discharge"
487 --------------------------------------
489 The main change in this release is the major audio format handler
490 cleanup which removes some similar/duplicate code and makes it easier
491 to implement plugins for other audio formats. Of course, the usual mix
492 of other improvements/changes/bugfixes also made it into the release.
494 - simplified audio format handlers (most of the handling functions
495 were moved one layer up to the virtual streaming system).
496 - para_server uses mmap to read audio files
497 - repositioning of mp3 streams is much faster, in particular for
498 jumping near the end of large mp3 files.
499 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
501 - fix a bug in para_filter that caused decoding of aac files
502 to start only after a few seconds.
503 - fix osx_writer hangs
504 - simplified dccp code (thanks to Gerrit Renker)
505 - the compress filter works also on big endian systems (ppc)
507 -----------------------------------------
508 0.2.15 (2007-02-16) "inductive resonance"
509 -----------------------------------------
511 Minor improvements, more documentation and a bunch of bug fixes.
513 - para_server: The server.users file is only read once on server
514 startup rather than for each connection
515 - mp3dec: Fix decoding of corrupt mp3 files
516 - afs (audio file sender) is now called vss (virtual streaming
517 system). Consequently, the permission flags specified in
518 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
519 become VSS_READ and VSS_WRITE respectively.
520 - para_audiod/para_filter: Fix a bug that caused the last chunk
521 of audio data not being written under certain circumstances
522 - audiod: compute the difference of server time and local time
524 - para_server/para_audiod: Fix some memory leaks
525 - documentation improvements
526 - configure.ac: fix checks for para_krell
529 -------------------------------------------
530 0.2.14 (2006-10-15) "transient singularity"
531 -------------------------------------------
533 The only major enhancement of this version is the osx writer which completes
534 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
535 until now for reasons beyond the scope of this changelog entry.
537 - new output plugin for Mac Os: the osx writer
538 - rename configure command line options from --enable-xxx-headers to
539 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
540 - configure: new command line options: --with-mad-headers,
541 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
542 - some robustness fixes
543 - dymamic audio format recognition for audiod
544 - para_server: new command line option: --autoplay_delay
545 - para_audiod: new command line option: --clock_diff_count
547 ---------------------------------------
548 0.2.13 (2006-07-14) "sonic convolution"
549 ---------------------------------------
551 A bunch of new features and core changes.
553 - the new paraslash scheduler, short and sweet.
554 - Support for m4a/mp4 files via the new aac audio format
555 handler/filter (requires libfaad).
556 - each writer has its own command line parser, just like
557 para_recv and para_filter.
558 - para_client and para_audioc use the error subsystem
559 - writers are integrated in para_audiod (currently linux-only)
560 - para_client is integrated in para_audiod
561 - random/playlist selector: improved info strings
562 - new audiod commands: tasks, kill
563 - update to libortp-0.10.1
564 - para_fade: wake time defaults to 8 hours from now
565 - update to autoconf-2.60
567 ------------------------------------------
568 0.2.12 (2006-05-12) "oriented abstraction"
569 ------------------------------------------
571 Many user-visible changes in this release and lots of new
575 - the new optional dccp sender/receiver. It uses the datagram
576 congestion control protocol. You'll need a fairly new kernel
578 - paraslash works on Mac OS X (thanks to Gerd Becker)
579 - para_play renamed to para_write
580 - modular output plugin design (writers) for para_write
581 - new file_writer output plugin for para_write
582 - compress filter speed improvements
583 - update to libortp-0.9.1
584 - update to gengetopt-2.17rc
585 - para_client no longer depends on libreadline (as the
586 code for the interactive mode was removed).
587 - gcc-2-95 is no longer a supported compiler. It may still
588 work, but it gets no more testing.
589 - the tarball no longer contains the screenshot images which
590 reduces its size quite a bit.
591 - configure: new command line options: --enable-mysql-headers
592 and --enable-mysql-libs
594 ------------------------------------
595 0.2.11 (2006-03-11) "atomic duality"
596 ------------------------------------
598 Here it is, the first paraslash release developed with git. There
599 are fairly many user-visible changes in this release. As two out of
600 the three "database tools" of paraslash don't use a database at all,
601 they are now called "audio file selectors" instead.
604 - the cdt command (change database tool) becomes chs (change
606 - no more colon separators: The syntax of some options of
607 para_audiod and para_filter have changed. Use --help for
608 more info (and some examples).
609 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
610 - switch from cvs to git (should've done that earlier)
611 - the new ipc subsystem
612 - new audio file selector: playlist
613 - para_server: the dopey selector is now called "random",
614 and is the default selector. Use the --selector option to
615 choose another selector at startup, or the chs command to
616 change the selector at runtime.
617 - X86_64 fixes (thanks to Steffen Klassert)
620 --------------------------------------
621 0.2.10 (2006-02-17) "cyclic attractor"
622 --------------------------------------
624 Huge documentation update, a scrollable window for para_gui, ortp
625 improvements, and of course many small fixes not mentioned here.
626 The diffstat below is rather misleading as most insertions are due
627 to the new source documentation.
630 - para_server also uses the new error subsystem
631 - lots of new documentation (UTSL)
633 - keysyms for cursor keys and for next/previous page keys
634 - scrollable output window
635 - new internal commands: scroll up/down, page up/down
636 - fix color of command output.
637 - ortp: the --chunk_time and --header flags are no longer needed
638 for para_recv/para_audiod as this information is now encoded in
639 each rtp packet sent by para_server.
641 -------------------------------------------
642 0.2.9 (2006-01-24) "progressive turbulence"
643 -------------------------------------------
645 Internal audiod receivers/filters, the new error subsystem and
646 a lot of small improvements.
648 - para_recv and para_filter are integrated into the para_audiod
649 binary, i.e. audiod no longer spawns a new process for
650 each receiver/filter. As para_recv and para_filter might be
651 useful as standalone programs, they still get built (linked
652 against the same object files that are also used for audiod).
653 - further ortp timing improvements should reduce the CPU usage
654 of the ortp receiver.
655 - improved audio grabbing. The 'grab' command of para_audiod
656 has its own set of command line options. Read the output of
657 "para_audioc help grab" for more info.
658 - oggdec: configurable input prebuffer size.
659 - the new error subsystem gives better error diagnostics
660 and reduces code size.
662 -----------------------------------------
663 0.2.8 (2006-01-02) "dynamic accumulation"
664 -----------------------------------------
666 The new modular filter design and the para_play-hangs bugfix.
668 - new executable: para_filter. It combines para_mp3dec,
669 para_oggdec and para_compress. It also adds a further filter
670 type, wav, that just inserts a wave header at the desired point
671 of the filter chain. All 'piping' is done in-memory (i.e. no
672 read/write operations are used).
673 - para_play: fix a stupid bug that caused it to hang under
674 certain circumstances.
676 -------------------------------------------
677 0.2.7 (2006-12-27) "transparent invariance"
678 -------------------------------------------
680 Not many user-visible changes but a fair amount of internal improvements.
683 - The http sender buffers data if it can not be sent
684 out immediately (because the socket is not writable). This
685 should prevent para_server from shutting down the connection
686 too early on a loaded network.
687 - para_play also prebuffers data if it is told to start at a
688 future time by the --start_time option.
689 - The return of para_recv: It combines para_ortp_recv and
690 para_http_recv. Use the --receiver option to switch between
691 the two. para_recv builds without libortp, but contains
692 only the http receiver in this case.
693 - update to ortp 0.8.1. As this ortp release contains incompatible
694 changes, para_recv-0.2.7 won't link against older ortp libs.
695 - improved ortp timings.
696 - use of gcc-extensions that #define away for non-gcc and
699 -------------------------------------------
700 0.2.6 (2005-10-29) "recursive compensation"
701 -------------------------------------------
703 Transparent session encryption (uses openssl's Alleged RC4 cipher),
704 the internal find command and several other improvements and cleanups.
706 - Encrypt the session if encryption is requested by the client
707 (default for para_client 0.2.6). This is backwards
708 compatible, so older clients can still connect to para_server
709 0.2.6. Use the new client option --plain to request an
710 uncrypted session (off by default, must be set to on in
711 order to connect to para_server 0.2.x with 0 <= x <= 5).
712 - para_server uses an internal function to locate audio files
713 rather than calling find(1). The server option
714 --mysql_audio_file_dir replaces --mysql_find_cmd.
715 - documentation update
717 - header file cleanup
718 - para_client code cleanup
719 - para_gui: faster display of output of display commands
721 ------------------------------------------
722 0.2.5 (2005-10-13) "aggressive resolution"
723 ------------------------------------------
725 This release adds internal senders, i.e. no more external programs are
726 spawned for sending out the audio data. There are two different senders
727 available: The http sender and the ortp sender (former para_send which
728 is no longer needed).
730 The new sender code has a plugin-like design so it can be easily
731 extended should there be be any future need for supporting another
732 network streaming protocol. All senders are completely independent of
733 each other. In particular, the http and the ortp sender can operate
736 - new server command: sender to control senders at runtime.
737 Read the output of "para_server -h" and "para_client help
738 sender" for more information.
739 - para_recv renamed to para_ortp_recv
740 - new executable: para_http_recv, a simple command line
742 - major afs/mp3/ogg code simplifications due to internal
744 - ogg timing improvements
745 - fix several minor memory leaks (found by valgrind)
746 - empty stream definitions work again
747 - com_ne(): ignore errors on remove
748 - audiod: fix segfault on server restart
750 ---------------------------------------
751 0.2.4 (2005-09-21) "toxic anticipation"
752 ---------------------------------------
754 Several small improvements, fixes and the new grab command.
757 - new command: "grab" to grab the output of the stream reader
758 or any filters. Read the output of "para_audioc help grab"
759 for more information.
762 - audioc: new command line option: --bufsize to specify a
763 buffer size different from the default size 8192.
764 - improved error diagnostics for para_play.
765 - new configure option: --enable-ssldir so search for openssl in
767 - sdl_gui: Make it look nice again for 1024x768
768 - server: report total size of memory allocated with sbrk by malloc,
769 new command line option: --announce_time
771 -----------------------------------------
772 0.2.3 (2005-09-01) "hydrophilic movement"
773 -----------------------------------------
775 Two new executables and major feature enhancements.
777 - audiod filters: It is now possible to specify arbitrary many
778 (including none) filters for each supported audio
779 format. This can be used e.g. for normalizing volume,
780 transforming or grabbing the audio stream, or for using
781 visualizers. Read the output of "para_audiod -h" for the
782 syntax of the new --filter_cmd option.
783 - new executable: para_play, a tiny alsa player. It
784 can play wave files or raw pcm (16 bit little endian)
786 - new executable: para_compress, a dynamic range compressor
787 intended to keep audio output at a consistent volume. Derived
788 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
789 - audiod: New option: --stream_delay. This can be used in
790 a local network to syncronize the audio output of all
791 clients that play the same stream.
793 ------------------------------------------
794 0.2.2 (2005-08-19) "tangential excitation"
795 ------------------------------------------
797 Mostly internal changes in this release, but also some new commands
798 for the mysql database tool.
800 - cleanup exec.c, fix para_exec bug
801 - compile time loglevel (log messages below the given level
802 won't be compiled in, which reduces the size of the
804 - new log macros that shorten the size of the source code.
805 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
806 to send only zeros. With this workaround, para_audioc works
808 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
809 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
810 (new entry), "snp" (set numplayed). Read the manual for more
813 ---------------------------------------
814 0.2.1 (2005-08-15) "surreal experience"
815 ---------------------------------------
817 Here comes paraslash-0.2.1. It contains a couple of new features and,
818 surprise, only minor bug fixes.
820 - kill noisy mp3 debug message
821 - cleanup of the build system
822 - para_server and para_client directly use the crypto routines
823 of the openssl library rather than invoking the openssl command
825 - server/audiod: new option --user to switch to the given user
826 when invoked as root. Read the output of "para_server -h" for
828 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
829 status. Default: "para_audioc stat"
830 - sdl_gui: new option --pic_cmd to be used to download the picture.
831 Default: "para_client pic"
832 - audiod: 5 slots ought to be enough for everybody
833 - audiod: new status item: Uptime, kill hup command
835 ------------------------------------------
836 0.2.0 (2005-08-06) "distributed diffusion"
837 ------------------------------------------
839 After several month of increased development activity, paraslash-0.2.0
840 has arrived. It contains many new features and is much more
841 self-contained than the old 0.1.x series. Enjoy!
844 - para_server: fix hang on song change and crash on sighup.
845 Speed up mysql queries. The DIR_LIKE macro is gone.
846 - new executables: para_audiod, the local audio daemon that
847 starts playback (uses SCM_CREDENTIALS socket magic) and
848 para_audioc, the corresponding client.
849 - new executables: para_mp3dec/para_oggdec, two really teensy
850 decoders. para_mp3dec is based on libmad, para_oggdec requires
852 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
853 they are now called para_send and para_recv respectively.
854 - documentation updates
855 - para_gui is themable. For now there is the default theme that
856 looks as before and the simple theme: blue and easy.
857 - gui: audio streaming is now handled by audiod. Time display shows
858 playback time rather than streaming time
859 - slider: update to libzmw-0.2.0
860 - para_krell: fix crash on server shutdown
861 - switch from gzip to bzip2
863 ----------------------------------------
864 0.1.7 (2005-04-18) "melting penetration"
865 ----------------------------------------
867 The main change in this release is clearly the oggvorbis rewrite,
868 but there are also lots of smaller changes. If you intend to use both
869 the mp3 and the ogg plugin, it is recommended to use software mixing,
870 e.g. the dmix plugin which is provided by ALSA.
872 - new executables: para_ovsend and para_ovrecv for sending/receiving
873 oggvorbis files via rtp. Requires the open rtp library. Get it at
874 http://www.linphone.org/ortp/
875 - rewrite of the ogg_vorbis core code
876 - configure detects libzmw and, if detected, includes
877 para_slider to the list of binaries to be built by make
878 - server stream writers read from their associated fifo rather
880 - slider: two new sliders, lastplayed and numplayed
881 - fix nasty double free bug which caused random segfaults in case of
882 mp3 files with invalid header information
883 - gui: new command line option: --stream_timeout=seconds to
884 deactivate a slot if it is idle for that many seconds (default=`5')
887 ---------------------------------------
888 0.1.6 (2005-03-05) "asymptotic balance"
889 ---------------------------------------
891 Only little user-visible changes in this release. Mainly bugfixes and
892 core code cleanup. This is probably the most stable version ever if you
895 - fix several memory leaks
896 - rename default name of mysql database from "music" to "paraslash".
897 Use para_server's --mysql_database option if you do not want to
898 rename your old database.
899 - rework ogg vorbis code
900 - make update command work on mysql servers with LOCAL_INFILE
902 - gui: improved stream I/O (slots)
903 - simplified audio format API
904 - para_pob_ogg is gone
906 ------------------------------------
907 0.1.5 (2004-12-31) "opaque eternity"
908 ------------------------------------
910 Let's slide gently into the new year.
912 - new: para_slider (not built automatically, type "make
913 para_slider" to build). A toy for those who always felt that
914 creating stream definitions is difficult. See screenshots,
915 README and FEATURES for more info.
916 - improved signal handling. Fixes server segfault on SIGHUP
917 for linux kernels newer than Aug 24 2004 and makes para_gui
919 - reload database tool on SIGHUP
920 - improved help message for sl
921 - do not log "broken pipe" messages as errors. They are
923 - fix wrong error message on permission errors
925 -----------------------------------------
926 0.1.4 (2004-12-19) "tunneling transition"
927 -----------------------------------------
929 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
930 Hopefully, most of them got wiped out with this release. Some
931 enhancements went also in.
933 - improved error diagnostics for all commands
934 - stradd/picadd: overwrite previous contents if entry already
935 exists, rather than returning errors
936 - stradd: use current stream if invoked without args
937 - faster (and hopefully more stable) ogg-vorbis handling
938 - para_krell: reap children to avoid zombie-flooding in case
940 - si: report also server pid
941 - server: don't busy-loop if dbtool reports only invalid files.
942 - gui: CTRL+C works again, fix stream_read command line option
944 - fix mysql dbtool startup in case no database exists
945 - many small fixes and cleanups
947 ---------------------------------------
948 0.1.3: (2004-12-10) "vanishing inertia"
949 ---------------------------------------
951 Starting from this release, the database tools are integrated in the
952 server binary. This decreases server startup time, reduces code size
953 and speeds up database commands. However, the layout of the underlying
954 mysql database changed only slightly and 0.1.3 should be backwards
955 compatible in that respect.
959 - If mysql is not detected at compile time, or fails to init
960 at runtime, fall back to the dopey database tool which should
962 - para_dbtool and dbtool.conf are gone. All mysql specific
963 options are read from server.conf and are prefixed by 'mysql_'.
964 - new command: cdt (change database tool)
965 - new command line option: dbtool (choose startup database tool)
966 - The name of current stream is now stored in the database,
967 so paraslash remembers its current stream when restarted.
968 - new command: csp (change stream and play)
969 - para_gui also reports current database tool and server uptime
971 -------------------------------------------
972 0.1.2: (2004-11-28) "spherical fluctuation"
973 -------------------------------------------
975 Point release before the big dbtool changes go in.
977 - dbtool: rename ca to cam (copy all meta data). It now also
978 copies numplayed and lastplayed time as well as the picture
980 - fix endless-loop-bug caused by mp3 files with invalid header
982 -----------------------------------------
983 0.1.1: (2004-11-05) "floating atmosphere"
984 -----------------------------------------
987 - new dbtool command: mbox. Browse your sound-file collection
988 with your favorite mail reader.
989 - several small fixes
991 -------------------------------------
992 0.1.0: (2004-10-22) "rotating cortex"
993 -------------------------------------
995 - fix logging bug for loglevel > VERBOSE
997 - correct timings for vbr mp3s
998 - modular audio format support
999 - ogg-vorbis support (experimental)
1000 - new server option: autoplay
1002 -----------------------------------------
1003 0.0.99: (2004-07-25) "harmonic deviation"
1004 -----------------------------------------
1006 - rename projectname from icc to paraslash (play, archive, rate
1007 and stream large audio sets happily)
1008 - paraslash is no longer restricted to one particular audio
1010 - new dbtool commands (stradd, strq, strdel) for easy stream
1011 managment w/o configuration file. That obsoletes stream_defs
1012 file/config option for dbtool.
1013 - picadd accepts jpeg data from stdin
1014 - new server commands: ps (select previous stream), sc (song change)
1015 - new default pictures for sdl_gui
1016 - gui: new key_map option for binding commands and internal
1017 functions to arbitrary keys, nice help screen, rip out
1018 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1019 show silly logo on startup
1020 - new executables: para_fade for fading volume, para_dbadm for
1021 manipulating attributes
1022 - cdb adds _all_ tables to mysql database
1023 - revised and beautified documentation
1024 - sample dbtool rewritten in C
1027 ---------------------------------------------
1028 0.0.98: (2003-12-26) "incremental smoothness"
1029 ---------------------------------------------
1031 - kick icecast in favour of poc. That removes some races and reduces
1032 core code considerably.
1033 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1034 give finer info on afs' status.
1035 - gui can start decoder (see config options). Further new gui
1036 commands: refresh (^L), jmp (F1-F10)
1037 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1038 terminates gui. This fixes dead instances consuming memory
1040 - new dbtool command: verb for sending verbatim sql queries.
1041 - fix pid_list races (by removing pid_list)
1044 --------------------
1045 0.0.97: (2003-10-26)
1046 --------------------
1048 - installation prefix now defaults to /usr/local
1049 - new commands for gui: snozze, sleep and reread config
1050 - config file for gui and sdl_gui
1051 - fix problems with filenames containing funny characters
1052 (reported by Thomas Forell)
1053 - improved signal handling for gui, now it rereads conf on SIGHUP
1054 - new dbtool command: cdb (create database)
1055 - switch from argtable to gengetopt
1056 - major code cleanup and speed improvements
1057 - fix several potential buffer overflows
1058 - many small fixes and cleanups
1064 - easy stream_defs syntax
1065 - sdl_gui can display images associated to the file being played
1066 - Major feature enhancements for icc_gui including dynamic text
1067 placement and the top/bottom window design
1068 - vrfy/clean now also checks for NULL values in attributes as
1069 well as for invalid picture pointers
1070 - fix long outstanding case sensitivity bug
1071 - many small fixes and cleanups
1077 - sdl gui runs much faster
1078 - new dbtool command: ca (copy attributes)
1079 - count and display number of times the song has been played
1080 - new feature: scoring
1081 - command line options for sdl_gui
1082 - simpler syntax of streams file
1083 - decrease network traffic of stat
1085 - many small fixes and cleanups
1091 - new server command: ns (next stream)
1092 - new icc_gui command: c (change stream)
1094 - stat shows also id3 tag info
1096 - log flodding bug fixed
1097 - many small fixes and cleanups
1103 - colors for icc_gui
1104 - icc_gui sets volume directly (linux only)
1105 - proper locking that fixes some races
1106 - fix security bug that caused commands to be executed even
1107 with unsufficient permissions
1108 - new command: hup to make all servers reread their configuration file
1109 - icecast meta data streaming
1110 - many small fixes and cleanups
