4 --------------------------------------------
5 Noteworthy changes recently merged to master
6 --------------------------------------------
8 - The sideband compatibility code has been removed, hence
9 sideband connections (introduced in 0.4.11) are now mandatory.
10 - Addblob commands can produce output.
11 - The stat command no longer sends garbage when para_server was
12 compiled against libgcrypt.
14 --------------------------------------
15 0.4.13 (2013-07-29) "spectral gravity"
16 --------------------------------------
18 One more 0.4.x release before the API-breaking changes for 0.5.0 go
19 in. The main features of this release are the ogg/opus audio format,
20 and UTF-8 support, but it includes also tons of other improvements
21 and fixes all over the place.
23 - New audio format: ogg/opus.
24 - UTF8 support for para_gui and the mp3 audio format handler.
25 - Scheduler improvements and fixes.
26 - The obsolete gettimeofday() function has been replaced
27 by clock_gettime() on systems which support it.
28 - Speed and usability improvements for para_gui.
29 - para_client now restores the fd flags of stdin and stdout
31 - Improved manual pages.
32 - Consistent version strings for all executables.
33 - Reduced dependencies on generated files result in fewer
34 recompilations on changes.
35 - Performance improvements for the compress filter.
36 - Improved downloads web page.

41 -----------------------------------------
42 0.4.12 (2012-12-20) "volatile relativity"
43 -----------------------------------------
44 The new command line player, the resample filter, ALSA support for
45 para_fade, and the improved build system are the highlights of this
46 release which probably marks the end of the 0.4.x series.
48 - The afh receiver and the para_play executable.
49 - The resample filter: A sample rate converter based on
51 - The "versions" directory has been removed from the master
52 branch. The tarballs of the old releases are now available
53 in the new "releases" branch.
54 - Overhaul of the build system: All generated files are now
55 written to the "build" directory.
56 - The modular mixer API and the alsa mixer.
57 - Minor fixes for the osx writer.
59 --------------------------------------
60 0.4.11 (2012-07-20) "mutual diversity"
61 --------------------------------------
63 The major feature in this release is the new sideband API for
64 client-server communication. This API will be used exclusively starting
65 with 0.5.0, which breaks backward compatibility but allows to get rid
66 of quite some compatibility code. Other noteworthy changes include
67 decoder latency improvements and a long-standing bug fix for the
70 - Sideband connections: If both para_server and para_client
71 support this feature, data is sent as a multiplexed stream.
72 - The --no_default_filters option of para_filter has been
74 - Several fixes and latency improvements to various decoders.
75 - The ALSA writer now limits the prebuffer time to 500ms.
76 - Documentation improvements.
77 - Overhaul of the command_util.sh script.
78 - Fixes for some minor problems found by the clang analyzer.
79 - Compiles (almost) without warnings on gcc-3.
80 - Robustness improvements of the buffer tree code.
82 ------------------------------------------
83 0.4.10 (2012-03-30) "heterogeneous vacuum"
84 ------------------------------------------
86 Nothing earth-shaking in this release, but quite a few usability
87 improvements and the usual mix of cleanups and fixes.
89 - The --no_default_filters option of para_filter has been
90 deprecated. It still works but has no effect and will be
91 removed in the next version.
92 - para_gui now prints also the stderr output of the executing
93 command in the bottom window.
94 - Cleanup and consolidation of the various wrappers for
95 write(), writev(), send() and friends.
96 - The obscure error messages on mmap() failures have been
97 replaced by meaningful messages. This affects mainly
99 - para_audioc: Cleanups and memory leak fixes.
100 - Test 0004-server no longer fails if para_server is not
102 - New configure options: --with-id3tag-{headers,libs}.
104 -------------------------------------
105 0.4.9 (2011-12-06) "hybrid causality"
106 -------------------------------------
108 Support for another audio format, interactive mode for para_client
109 and para_audiod and many small improvements/fixes all over the place.
111 - Support for flac, the free lossless audio codec.
112 - Fix for an endless loop in the mp3 decoder for certain
114 - When executed without specifying a command, para_client
115 and para_audioc start an interactive shell (requires
116 libreadline being installed). The interactive mode offers
117 full tab completion and command line history.
118 - autogen.sh now detects a distcc setup and adjusts the
119 parameter for the -j option of make accordingly.
120 - Shared memory areas are no longer restricted to 64K. We now
121 detect the maximal size of a shared memory area at runtime.
122 - cleanup of the internal uptime API.
123 - para_server prefaults the mmapped audio file to avoid
124 delays on slow media.
125 - A new test for the test-suite that exercises the
126 communication between para_server and para_audiod.
127 - The alsa writer eats up less CPU cycles when configured to
129 - Simplified and unified receiver code.
131 - Commands which print a list of matching audio files now
132 emit a meaningful error message if no audio file matched the
135 --------------------------------------
136 0.4.8 (2011-08-19) "nested assignment"
137 --------------------------------------
139 Gcrypt support, the overhauled osx writer and regex format specifiers
140 are the highlights of this release.
142 - support for libgcrypt as a drop-in replacement for openssl.
143 Run configure --enable-cryptolib=gcrypt to link against
144 libgcrypt. The two crypto implementations are compatible to
145 each other, i.e. a para_client executable linked against
146 gcrypt can connect to para_server linked against libssl
148 - Rewrite of the osx writer (output plugin for Mac OS).
149 - audiod: The format specifier for receivers, filters and
150 writers is now treated as a regular expression. This allows
151 to replace 5 lines in the config file (one for each audio
152 format) by one single line. See the manual for details.
153 - The *.cmdline.[ch] files are no longer contained in the released
154 tarballs. This reduces the size of the tarballs but requires
155 gengetopt to build the tarball.
156 - Compiles cleanly also with llvm/clang.
157 - Corrupt mp3 files are handled more gracefully.
158 - The alsa writer uses poll fds instead of computing timeouts.
159 - Cleanup of the generic writer API.
160 - sched: Optimized zero timeouts.
161 - vss timeout cleanups.
162 - oggdec fixes and improvements.
164 --------------------------------------
165 0.4.7 (2011-06-01) "infinite rollback"
166 --------------------------------------
168 The new ao writer, support for ssh RSA keys and a couple of other
171 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
172 platforms through the libao audio library.
173 - Support for RSA keys generated with ssh-keygen.
174 - configure: improved options for ogg/vorbis/speex.
175 - The git version reported by --version always matches HEAD.
176 - The autogen script detects the number of processors and
177 runs a parallel make if possible.
178 - Major cleanup of the crypto API.
179 - Documentation updates.
181 ------------------------------------------
182 0.4.6 (2011-03-31) "deterministic entropy"
183 ------------------------------------------
185 Lots of ogg/vorbis improvements, the new test suite, enhancements
186 for para_gui and a fair amount of other bug fixes.
188 - For DCCP/OGG streams the audio file header is only sent once
189 at the beginning of the stream rather than periodically
190 every five seconds. This reduces network traffic and the
192 - The vorbis comment header is replaced by an empty dummy header
193 before the header is sent over the network. This also results in
194 less network traffic and smaller FEC groups.
195 - The new "test" make target allows to perform some sanity checks prior
196 to installing the package.
197 - ogg timing fixes and performance improvements
198 - Scheduler improvements
199 - Proper exit codes for para_write
200 - para_gui: New option --theme to select a startup theme. Several
201 other improvements and fixes.
202 - aacdec error message cleanups
203 - simplified color error handling
205 --------------------------------------------
206 0.4.5 (2010-12-17) "symmetric randomization"
207 --------------------------------------------
209 Bug fixes, internal cleanups and variable-sized FEC slices.
211 - Contains a fix for an invalid-free-bug in the ogg audio format
213 - Switching off the DCCP sender works again.
214 - para_audiod handles crashes of para_server more robustly.
215 - Internal scheduler and writer cleanups.
216 - Reduced latency due to variable-sized FEC slices.
217 - Improved documentation and error diagnostics.
218 - The build of para_server is now optional, allowing the build
219 to succeed in case libosl is not installed.
221 ------------------------------------------
222 0.4.4 (2010-08-06) "persistent regularity"
223 ------------------------------------------
225 Support for yet another audio format, para_write improvements and
228 - Support for the speex codec.
229 - Support for sample formats other than 16 bit little endian.
230 - error2.h is now created by a perl script which speeds up configure
232 - Fix a bug in the aac decoder which could lead to segfaults in
233 para_filter/para_audiod.
234 - Fixes for autoconf-2.66.
236 ----------------------------------------
237 0.4.3 (2010-07-05) "imaginary radiation"
238 ----------------------------------------
240 Many improvements for the DCCP and the UDP transport, the new user
241 manual and the usual mix of bug fixes and internal improvements.
243 - FEC support for the DCCP sender (Gerrit Renker). The new
244 --dccp_max_slice_size, --dccp_data_slices_per_group and
245 --dccp_slices_per_group options can be used to set the FEC
246 parameters for the DCCP transport.
247 - DNS lookups for UDP targets (Gerrit Renker).
248 - The new user manual replaces the README, README.afs, REQUIREMENTS
249 and INSTALL documents.
250 - Fix an end-of-file detection bug in the oggdec filter.
251 - The new nonblock API.
252 - Both options of the oggdec filter have been removed.
253 - New debug mode for the internal scheduler.
255 ------------------------------------------
256 0.4.2 (2010-04-23) "associative expansion"
257 ------------------------------------------
259 It's been some time since the last release, but finally here is
260 paraslash-0.4.2. The bulk of the changes comes from the new buffer
261 tree API, but there are changes all over the tree. Mainly performance
262 and usability improvements, but also quite some bug fixes.
264 - The new buffer tree API.
265 - DCCP: Support for CCID negotiation (Gerrit Renker).
266 - UDP robustness fixes.
267 - The --bufsize option for mp3dec is gone as it no longer makes sense
268 for the new buffer tree API.
269 - Fix audible buffer underruns for wma streams.
270 - The alsa writer no longer prints meaningless underrun durations.
271 - audiod: Defaults work also for udp streams. If no filter is
272 given for an audio format that is received via upd, fecdec is
273 automatically added as the first filter (along with the decoder).
275 ---------------------------------------
276 0.4.1 (2009-12-22) "concurrent horizon"
277 ---------------------------------------
279 Support for another audio format, minor feature enhancements and lots of bug
280 fixes. All fixes that have been accumulated in the maint branch (in particular
281 those mentionened in the 0.3.6 release notes) appear in this release as well.
284 - new afh option: --human to activate human-readable output.
285 - new server/audiod option: --log-timing to print timing information.
286 - build system improvements.
287 - source code documentation updates.
289 -------------------------------------
290 0.3.6 (2009-12-07) "cubic continuity"
291 -------------------------------------
293 Quite a few bugs have been found and fixed since 0.3.5, so here's
294 another 0.3.x release. No new features.
296 - Always check return value of malloc().
297 - ogg vorbis/FEC: Do not write garbage after the audio file header.
298 - exit if root privileges could not be dropped.
299 - FEC: Fix computation of extra slices.
300 - oss: Fix check for empty input buffer.
301 - Avoid buffer underruns due to filter chain output buffer constraints.
302 - server: Fix assignment of afs_pid.
303 - Don't panic if the afs database contains unknown audio formats.
304 - http/dccp: Do not send the audio file header twice.
305 - FEC: Timing improvements.
307 ----------------------------------------------
308 0.4.0 (2009-11-10) "simultaneous independence"
309 ----------------------------------------------
311 Two significant changes which require the new version number: The
312 improved authentication dialog and the fact that the database code
313 has been moved to a library, libosl. To use the new version, you have
314 to generate new RSA keys, see INSTALL for details. A shell script is
315 provided for conversion of the 0.3 database to the new 0.4 format.
317 - stronger crypto for client authentication
318 - the database code has been moved to a library
319 - improved status item handling
320 - cleanup of the build system
321 - The "-V" option now also prints the git version
322 - the new parser-friendly listing mode for the ls and stat commands
323 - mandatory rc4 encryption
324 - major audio format handler cleanups
325 - (id3,...) tags are no longer stored as a combined string in the database
326 - new mood methods: artist_matches, title_matches, comment_matches,
327 album_matches, year_maches, year.
329 --------------------------------------------
330 0.3.5 (2009-09-21) "symplectic separability"
331 --------------------------------------------
333 Full client support for *BSD Unixes, complete re-write of the ogg
334 vorbis audio format handler, various improvements all over the place
335 and the usual mix of bugfixes. This release marks the end of the 0.3
336 series if no serious problems show up.
338 - the new oss writer (supported on *BSD and Linux)
339 - rewrite of the ogg vorbis audio format handler. It's
340 recommended to replace the chunk tables of existing ogg
341 vorbis files in the afs database by re-adding these files
343 - support for netmask subsets (Gerrit Renker)
344 - the new prebuffer filter
345 - improved signal handling
346 - variable fec output buffer size
347 - improved FEC timing fixes audible buffer underruns in UDP mode
348 - --log_color actually works
349 - new ls option: -d (print dates as seconds after the epoch)
350 - update to gengetopt 2.22.2
351 - support for RSA keys of size > 512 bits
352 - new option "mixer_channel" for para_fade
354 -----------------------------------------
355 0.3.4 (2009-05-07) "elliptic inheritance"
356 -----------------------------------------
358 The new udp sender, forward error correction, colored logs and various
359 other improvements. As the udp sender does not depend on any special
360 libraries, it is built unconditionally.
362 - The udp sender replaces the ortp sender. The new code uses forward
363 error correction to protect against packet losses. Many thanks to
364 Gerrit Renker for providing ipv6 support.
365 - The default port for udp streaming now defaults to 8000, like
366 for the http and the dccp senders/receivers.
367 - Loglevels are now specified as symbolic names, e.g.
369 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
370 - para_server/para_audiod: Color support for log messages.
371 - new options for mp3dec: --ignore-crc, --bufsize
372 - new audiod option: --config-file.
373 - gengetopt cleanups.
374 - Improved help/man pages: The documentation of para_audiod,
375 para_recv, para_filter and para_write now also contains
376 all options of the available receivers/filters/writers. The
377 man page of para_fade contains a description of the different
379 - More source code documentation.
382 --------------------------------------------
383 0.3.3 (2008-12-01) "axiomatic perspectivity"
384 --------------------------------------------
386 Internal code cleanups, bug fixes, improved tag handling and the new
387 amplification filter.
389 - para_server uses the generic scheduling code.
390 - overhaul of the virtual streaming system.
391 - mp3: id3 version 2 support via libid3tag (optional)
392 - ogg: vorbis comment support.
393 - aac meta info support.
394 - mp3 audio format handler cleanups.
395 - new filter: "amp" to amplify the amplitude of the audio stream
396 - new status item/database entry: amplification. It is
397 used by the amp filter to pre-amplify the audio stream.
398 - fix a close-without-open bug in para_write.
399 - fix a bug in com_init() which was introduced in 0.3.2.
400 - better error diagnostics for para_client.
402 -----------------------------------------
403 0.3.2 (2008-04-11) "probabilistic parity"
404 -----------------------------------------
406 The new para_afh executable, scheduling and documentation improvements.
408 - new ls option: -lc (list chunk table)
409 - new executable: para_afh, the stand-alone audio file handler tool
410 - afs commands can send output more than SHMMAX (32MB on Linux). This
411 also reduces the memory usage of commands that produce large amounts
413 - major scheduler and audiod cleanups.
414 - more detailed and much nicer man pages.
416 ---------------------------------------
417 0.3.1 (2008-02-23) "liquid interaction"
418 ---------------------------------------
420 A mix of cleanups, bug fixes, improvements, and some new features. No
421 significant changes to the new database (osl) code, which is generally
424 - Share some similar/duplicate code between the http and the
426 - Generic access control lists for paraslash senders.
427 - dccp sender: Access control lists, connection limiting and support
428 for the allow,deny,on,off,help sender commands.
429 - The default dccp port changed from 5001 to 8000 (suggested by
431 - para_server starts even if not all public keys could be loaded.
432 - Audiod performance improvements.
433 - fix a bug in the "off" command of the http sender.
434 - fix some fd and memory leaks.
435 - Update to gengetopt-2.22.
437 -------------------------------------
438 0.3.0 (2008-01-12) "solar saturation"
439 -------------------------------------
441 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
444 Usually one might expect lots of new features AND a big increase in size
445 for a major release like this.
447 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
448 ever. The decrease in size is mostly due to the removal of some
449 graphical tools (which were only quick hacks anyway). But also the
450 fact that the mysql code is gone cuts down the size a bit.
452 Being independent of mysql comes at a cost: The fact that paraslash
453 now contains its own database (the object storage layer, osl) increases
454 the (stripped) binary size of para_server by ~50K on i386.
456 - no more restrictions on unique basenames.
457 - independent of mysql: The new self-contained object
458 storage layer (osl) replaces the mysql database.
459 - New executable para_fsck: Check integrity of osl tables.
461 - Reliable audio file move/rename detection.
462 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
463 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
465 - the new osl-based audio file selector (afs) replaces the random,
466 the playlist and the mysql selector of paraslash-0.2.x.
467 - IPv6 support (thanks to Gerrit Renker).
468 - paraslash-0.2.x streams are now called "moods". Writing
469 0.3.x-mood definitions should be both easier and more
470 powerful than writing 0.2.x-stream definitions.
471 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
472 been removed. The world is a better place without them. However,
473 para_gui is still there.
474 - afs tracks audio file selection also in playlist mode.
475 - few easy-to-use afs commands replace the many not-so-easy-to-use
476 mysql commands (and are available also in playlist mode).
477 - Improved error subsystem.
478 - The earth-shaking new logo.
480 -----------------------------------------
481 0.2.17 (2007-11-20) "isotropic threshold"
482 -----------------------------------------
484 Mainly bugfixes and cleanups in this version which marks the end of
485 the 0.2.x series if no serious bugs show up after the release.
487 - mysql_selector: fix a locking bug.
488 - universal chunk queueing.
489 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
491 - be more carful wrt. signed vs. unsigned argument passing.
492 - cleanup error.h and fix some references to invalid error
494 - update to gengetopt-2.21.
495 - update to ortp-0.13.1.
496 - autoconf: extend checks for headers, library functions and
497 compiler characteristics.
498 - Fix streaming of large mp3 files.
499 - Fix an off-by-one bug in playlist handling.
501 --------------------------------------
502 0.2.16 (2007-04-05) "neural discharge"
503 --------------------------------------
505 The main change in this release is the major audio format handler
506 cleanup which removes some similar/duplicate code and makes it easier
507 to implement plugins for other audio formats. Of course, the usual mix
508 of other improvements/changes/bugfixes also made it into the release.
510 - simplified audio format handlers (most of the handling functions
511 were moved one layer up to the virtual streaming system).
512 - para_server uses mmap to read audio files
513 - repositioning of mp3 streams is much faster, in particular for
514 jumping near the end of large mp3 files.
515 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
517 - fix a bug in para_filter that caused decoding of aac files
518 to start only after a few seconds.
519 - fix osx_writer hangs
520 - simplified dccp code (thanks to Gerrit Renker)
521 - the compress filter works also on big endian systems (ppc)
523 -----------------------------------------
524 0.2.15 (2007-02-16) "inductive resonance"
525 -----------------------------------------
527 Minor improvements, more documentation and a bunch of bug fixes.
529 - para_server: The server.users file is only read once on server
530 startup rather than for each connection
531 - mp3dec: Fix decoding of corrupt mp3 files
532 - afs (audio file sender) is now called vss (virtual streaming
533 system). Consequently, the permission flags specified in
534 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
535 become VSS_READ and VSS_WRITE respectively.
536 - para_audiod/para_filter: Fix a bug that caused the last chunk
537 of audio data not being written under certain circumstances
538 - audiod: compute the difference of server time and local time
540 - para_server/para_audiod: Fix some memory leaks
541 - documentation improvements
542 - configure.ac: fix checks for para_krell
545 -------------------------------------------
546 0.2.14 (2006-10-15) "transient singularity"
547 -------------------------------------------
549 The only major enhancement of this version is the osx writer which completes
550 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
551 until now for reasons beyond the scope of this changelog entry.
553 - new output plugin for Mac Os: the osx writer
554 - rename configure command line options from --enable-xxx-headers to
555 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
556 - configure: new command line options: --with-mad-headers,
557 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
558 - some robustness fixes
559 - dymamic audio format recognition for audiod
560 - para_server: new command line option: --autoplay_delay
561 - para_audiod: new command line option: --clock_diff_count
563 ---------------------------------------
564 0.2.13 (2006-07-14) "sonic convolution"
565 ---------------------------------------
567 A bunch of new features and core changes.
569 - the new paraslash scheduler, short and sweet.
570 - Support for m4a/mp4 files via the new aac audio format
571 handler/filter (requires libfaad).
572 - each writer has its own command line parser, just like
573 para_recv and para_filter.
574 - para_client and para_audioc use the error subsystem
575 - writers are integrated in para_audiod (currently linux-only)
576 - para_client is integrated in para_audiod
577 - random/playlist selector: improved info strings
578 - new audiod commands: tasks, kill
579 - update to libortp-0.10.1
580 - para_fade: wake time defaults to 8 hours from now
581 - update to autoconf-2.60
583 ------------------------------------------
584 0.2.12 (2006-05-12) "oriented abstraction"
585 ------------------------------------------
587 Many user-visible changes in this release and lots of new
591 - the new optional dccp sender/receiver. It uses the datagram
592 congestion control protocol. You'll need a fairly new kernel
594 - paraslash works on Mac OS X (thanks to Gerd Becker)
595 - para_play renamed to para_write
596 - modular output plugin design (writers) for para_write
597 - new file_writer output plugin for para_write
598 - compress filter speed improvements
599 - update to libortp-0.9.1
600 - update to gengetopt-2.17rc
601 - para_client no longer depends on libreadline (as the
602 code for the interactive mode was removed).
603 - gcc-2-95 is no longer a supported compiler. It may still
604 work, but it gets no more testing.
605 - the tarball no longer contains the screenshot images which
606 reduces its size quite a bit.
607 - configure: new command line options: --enable-mysql-headers
608 and --enable-mysql-libs
610 ------------------------------------
611 0.2.11 (2006-03-11) "atomic duality"
612 ------------------------------------
614 Here it is, the first paraslash release developed with git. There
615 are fairly many user-visible changes in this release. As two out of
616 the three "database tools" of paraslash don't use a database at all,
617 they are now called "audio file selectors" instead.
620 - the cdt command (change database tool) becomes chs (change
622 - no more colon separators: The syntax of some options of
623 para_audiod and para_filter have changed. Use --help for
624 more info (and some examples).
625 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
626 - switch from cvs to git (should've done that earlier)
627 - the new ipc subsystem
628 - new audio file selector: playlist
629 - para_server: the dopey selector is now called "random",
630 and is the default selector. Use the --selector option to
631 choose another selector at startup, or the chs command to
632 change the selector at runtime.
633 - X86_64 fixes (thanks to Steffen Klassert)
636 --------------------------------------
637 0.2.10 (2006-02-17) "cyclic attractor"
638 --------------------------------------
640 Huge documentation update, a scrollable window for para_gui, ortp
641 improvements, and of course many small fixes not mentioned here.
642 The diffstat below is rather misleading as most insertions are due
643 to the new source documentation.
646 - para_server also uses the new error subsystem
647 - lots of new documentation (UTSL)
649 - keysyms for cursor keys and for next/previous page keys
650 - scrollable output window
651 - new internal commands: scroll up/down, page up/down
652 - fix color of command output.
653 - ortp: the --chunk_time and --header flags are no longer needed
654 for para_recv/para_audiod as this information is now encoded in
655 each rtp packet sent by para_server.
657 -------------------------------------------
658 0.2.9 (2006-01-24) "progressive turbulence"
659 -------------------------------------------
661 Internal audiod receivers/filters, the new error subsystem and
662 a lot of small improvements.
664 - para_recv and para_filter are integrated into the para_audiod
665 binary, i.e. audiod no longer spawns a new process for
666 each receiver/filter. As para_recv and para_filter might be
667 useful as standalone programs, they still get built (linked
668 against the same object files that are also used for audiod).
669 - further ortp timing improvements should reduce the CPU usage
670 of the ortp receiver.
671 - improved audio grabbing. The 'grab' command of para_audiod
672 has its own set of command line options. Read the output of
673 "para_audioc help grab" for more info.
674 - oggdec: configurable input prebuffer size.
675 - the new error subsystem gives better error diagnostics
676 and reduces code size.
678 -----------------------------------------
679 0.2.8 (2006-01-02) "dynamic accumulation"
680 -----------------------------------------
682 The new modular filter design and the para_play-hangs bugfix.
684 - new executable: para_filter. It combines para_mp3dec,
685 para_oggdec and para_compress. It also adds a further filter
686 type, wav, that just inserts a wave header at the desired point
687 of the filter chain. All 'piping' is done in-memory (i.e. no
688 read/write operations are used).
689 - para_play: fix a stupid bug that caused it to hang under
690 certain circumstances.
692 -------------------------------------------
693 0.2.7 (2006-12-27) "transparent invariance"
694 -------------------------------------------
696 Not many user-visible changes but a fair amount of internal improvements.
699 - The http sender buffers data if it can not be sent
700 out immediately (because the socket is not writable). This
701 should prevent para_server from shutting down the connection
702 too early on a loaded network.
703 - para_play also prebuffers data if it is told to start at a
704 future time by the --start_time option.
705 - The return of para_recv: It combines para_ortp_recv and
706 para_http_recv. Use the --receiver option to switch between
707 the two. para_recv builds without libortp, but contains
708 only the http receiver in this case.
709 - update to ortp 0.8.1. As this ortp release contains incompatible
710 changes, para_recv-0.2.7 won't link against older ortp libs.
711 - improved ortp timings.
712 - use of gcc-extensions that #define away for non-gcc and
715 -------------------------------------------
716 0.2.6 (2005-10-29) "recursive compensation"
717 -------------------------------------------
719 Transparent session encryption (uses openssl's Alleged RC4 cipher),
720 the internal find command and several other improvements and cleanups.
722 - Encrypt the session if encryption is requested by the client
723 (default for para_client 0.2.6). This is backwards
724 compatible, so older clients can still connect to para_server
725 0.2.6. Use the new client option --plain to request an
726 uncrypted session (off by default, must be set to on in
727 order to connect to para_server 0.2.x with 0 <= x <= 5).
728 - para_server uses an internal function to locate audio files
729 rather than calling find(1). The server option
730 --mysql_audio_file_dir replaces --mysql_find_cmd.
731 - documentation update
733 - header file cleanup
734 - para_client code cleanup
735 - para_gui: faster display of output of display commands
737 ------------------------------------------
738 0.2.5 (2005-10-13) "aggressive resolution"
739 ------------------------------------------
741 This release adds internal senders, i.e. no more external programs are
742 spawned for sending out the audio data. There are two different senders
743 available: The http sender and the ortp sender (former para_send which
744 is no longer needed).
746 The new sender code has a plugin-like design so it can be easily
747 extended should there be be any future need for supporting another
748 network streaming protocol. All senders are completely independent of
749 each other. In particular, the http and the ortp sender can operate
752 - new server command: sender to control senders at runtime.
753 Read the output of "para_server -h" and "para_client help
754 sender" for more information.
755 - para_recv renamed to para_ortp_recv
756 - new executable: para_http_recv, a simple command line
758 - major afs/mp3/ogg code simplifications due to internal
760 - ogg timing improvements
761 - fix several minor memory leaks (found by valgrind)
762 - empty stream definitions work again
763 - com_ne(): ignore errors on remove
764 - audiod: fix segfault on server restart
766 ---------------------------------------
767 0.2.4 (2005-09-21) "toxic anticipation"
768 ---------------------------------------
770 Several small improvements, fixes and the new grab command.
773 - new command: "grab" to grab the output of the stream reader
774 or any filters. Read the output of "para_audioc help grab"
775 for more information.
778 - audioc: new command line option: --bufsize to specify a
779 buffer size different from the default size 8192.
780 - improved error diagnostics for para_play.
781 - new configure option: --enable-ssldir so search for openssl in
783 - sdl_gui: Make it look nice again for 1024x768
784 - server: report total size of memory allocated with sbrk by malloc,
785 new command line option: --announce_time
787 -----------------------------------------
788 0.2.3 (2005-09-01) "hydrophilic movement"
789 -----------------------------------------
791 Two new executables and major feature enhancements.
793 - audiod filters: It is now possible to specify arbitrary many
794 (including none) filters for each supported audio
795 format. This can be used e.g. for normalizing volume,
796 transforming or grabbing the audio stream, or for using
797 visualizers. Read the output of "para_audiod -h" for the
798 syntax of the new --filter_cmd option.
799 - new executable: para_play, a tiny alsa player. It
800 can play wave files or raw pcm (16 bit little endian)
802 - new executable: para_compress, a dynamic range compressor
803 intended to keep audio output at a consistent volume. Derived
804 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
805 - audiod: New option: --stream_delay. This can be used in
806 a local network to syncronize the audio output of all
807 clients that play the same stream.
809 ------------------------------------------
810 0.2.2 (2005-08-19) "tangential excitation"
811 ------------------------------------------
813 Mostly internal changes in this release, but also some new commands
814 for the mysql database tool.
816 - cleanup exec.c, fix para_exec bug
817 - compile time loglevel (log messages below the given level
818 won't be compiled in, which reduces the size of the
820 - new log macros that shorten the size of the source code.
821 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
822 to send only zeros. With this workaround, para_audioc works
824 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
825 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
826 (new entry), "snp" (set numplayed). Read the manual for more
829 ---------------------------------------
830 0.2.1 (2005-08-15) "surreal experience"
831 ---------------------------------------
833 Here comes paraslash-0.2.1. It contains a couple of new features and,
834 surprise, only minor bug fixes.
836 - kill noisy mp3 debug message
837 - cleanup of the build system
838 - para_server and para_client directly use the crypto routines
839 of the openssl library rather than invoking the openssl command
841 - server/audiod: new option --user to switch to the given user
842 when invoked as root. Read the output of "para_server -h" for
844 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
845 status. Default: "para_audioc stat"
846 - sdl_gui: new option --pic_cmd to be used to download the picture.
847 Default: "para_client pic"
848 - audiod: 5 slots ought to be enough for everybody
849 - audiod: new status item: Uptime, kill hup command
851 ------------------------------------------
852 0.2.0 (2005-08-06) "distributed diffusion"
853 ------------------------------------------
855 After several month of increased development activity, paraslash-0.2.0
856 has arrived. It contains many new features and is much more
857 self-contained than the old 0.1.x series. Enjoy!
860 - para_server: fix hang on song change and crash on sighup.
861 Speed up mysql queries. The DIR_LIKE macro is gone.
862 - new executables: para_audiod, the local audio daemon that
863 starts playback (uses SCM_CREDENTIALS socket magic) and
864 para_audioc, the corresponding client.
865 - new executables: para_mp3dec/para_oggdec, two really teensy
866 decoders. para_mp3dec is based on libmad, para_oggdec requires
868 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
869 they are now called para_send and para_recv respectively.
870 - documentation updates
871 - para_gui is themable. For now there is the default theme that
872 looks as before and the simple theme: blue and easy.
873 - gui: audio streaming is now handled by audiod. Time display shows
874 playback time rather than streaming time
875 - slider: update to libzmw-0.2.0
876 - para_krell: fix crash on server shutdown
877 - switch from gzip to bzip2
879 ----------------------------------------
880 0.1.7 (2005-04-18) "melting penetration"
881 ----------------------------------------
883 The main change in this release is clearly the oggvorbis rewrite,
884 but there are also lots of smaller changes. If you intend to use both
885 the mp3 and the ogg plugin, it is recommended to use software mixing,
886 e.g. the dmix plugin which is provided by ALSA.
888 - new executables: para_ovsend and para_ovrecv for sending/receiving
889 oggvorbis files via rtp. Requires the open rtp library. Get it at
890 http://www.linphone.org/ortp/
891 - rewrite of the ogg_vorbis core code
892 - configure detects libzmw and, if detected, includes
893 para_slider to the list of binaries to be built by make
894 - server stream writers read from their associated fifo rather
896 - slider: two new sliders, lastplayed and numplayed
897 - fix nasty double free bug which caused random segfaults in case of
898 mp3 files with invalid header information
899 - gui: new command line option: --stream_timeout=seconds to
900 deactivate a slot if it is idle for that many seconds (default=`5')
903 ---------------------------------------
904 0.1.6 (2005-03-05) "asymptotic balance"
905 ---------------------------------------
907 Only little user-visible changes in this release. Mainly bugfixes and
908 core code cleanup. This is probably the most stable version ever if you
911 - fix several memory leaks
912 - rename default name of mysql database from "music" to "paraslash".
913 Use para_server's --mysql_database option if you do not want to
914 rename your old database.
915 - rework ogg vorbis code
916 - make update command work on mysql servers with LOCAL_INFILE
918 - gui: improved stream I/O (slots)
919 - simplified audio format API
920 - para_pob_ogg is gone
922 ------------------------------------
923 0.1.5 (2004-12-31) "opaque eternity"
924 ------------------------------------
926 Let's slide gently into the new year.
928 - new: para_slider (not built automatically, type "make
929 para_slider" to build). A toy for those who always felt that
930 creating stream definitions is difficult. See screenshots,
931 README and FEATURES for more info.
932 - improved signal handling. Fixes server segfault on SIGHUP
933 for linux kernels newer than Aug 24 2004 and makes para_gui
935 - reload database tool on SIGHUP
936 - improved help message for sl
937 - do not log "broken pipe" messages as errors. They are
939 - fix wrong error message on permission errors
941 -----------------------------------------
942 0.1.4 (2004-12-19) "tunneling transition"
943 -----------------------------------------
945 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
946 Hopefully, most of them got wiped out with this release. Some
947 enhancements went also in.
949 - improved error diagnostics for all commands
950 - stradd/picadd: overwrite previous contents if entry already
951 exists, rather than returning errors
952 - stradd: use current stream if invoked without args
953 - faster (and hopefully more stable) ogg-vorbis handling
954 - para_krell: reap children to avoid zombie-flooding in case
956 - si: report also server pid
957 - server: don't busy-loop if dbtool reports only invalid files.
958 - gui: CTRL+C works again, fix stream_read command line option
960 - fix mysql dbtool startup in case no database exists
961 - many small fixes and cleanups
963 ---------------------------------------
964 0.1.3: (2004-12-10) "vanishing inertia"
965 ---------------------------------------
967 Starting from this release, the database tools are integrated in the
968 server binary. This decreases server startup time, reduces code size
969 and speeds up database commands. However, the layout of the underlying
970 mysql database changed only slightly and 0.1.3 should be backwards
971 compatible in that respect.
975 - If mysql is not detected at compile time, or fails to init
976 at runtime, fall back to the dopey database tool which should
978 - para_dbtool and dbtool.conf are gone. All mysql specific
979 options are read from server.conf and are prefixed by 'mysql_'.
980 - new command: cdt (change database tool)
981 - new command line option: dbtool (choose startup database tool)
982 - The name of current stream is now stored in the database,
983 so paraslash remembers its current stream when restarted.
984 - new command: csp (change stream and play)
985 - para_gui also reports current database tool and server uptime
987 -------------------------------------------
988 0.1.2: (2004-11-28) "spherical fluctuation"
989 -------------------------------------------
991 Point release before the big dbtool changes go in.
993 - dbtool: rename ca to cam (copy all meta data). It now also
994 copies numplayed and lastplayed time as well as the picture
996 - fix endless-loop-bug caused by mp3 files with invalid header
998 -----------------------------------------
999 0.1.1: (2004-11-05) "floating atmosphere"
1000 -----------------------------------------
1003 - new dbtool command: mbox. Browse your sound-file collection
1004 with your favorite mail reader.
1005 - several small fixes
1007 -------------------------------------
1008 0.1.0: (2004-10-22) "rotating cortex"
1009 -------------------------------------
1011 - fix logging bug for loglevel > VERBOSE
1013 - correct timings for vbr mp3s
1014 - modular audio format support
1015 - ogg-vorbis support (experimental)
1016 - new server option: autoplay
1018 -----------------------------------------
1019 0.0.99: (2004-07-25) "harmonic deviation"
1020 -----------------------------------------
1022 - rename projectname from icc to paraslash (play, archive, rate
1023 and stream large audio sets happily)
1024 - paraslash is no longer restricted to one particular audio
1026 - new dbtool commands (stradd, strq, strdel) for easy stream
1027 managment w/o configuration file. That obsoletes stream_defs
1028 file/config option for dbtool.
1029 - picadd accepts jpeg data from stdin
1030 - new server commands: ps (select previous stream), sc (song change)
1031 - new default pictures for sdl_gui
1032 - gui: new key_map option for binding commands and internal
1033 functions to arbitrary keys, nice help screen, rip out
1034 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1035 show silly logo on startup
1036 - new executables: para_fade for fading volume, para_dbadm for
1037 manipulating attributes
1038 - cdb adds _all_ tables to mysql database
1039 - revised and beautified documentation
1040 - sample dbtool rewritten in C
1043 ---------------------------------------------
1044 0.0.98: (2003-12-26) "incremental smoothness"
1045 ---------------------------------------------
1047 - kick icecast in favour of poc. That removes some races and reduces
1048 core code considerably.
1049 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1050 give finer info on afs' status.
1051 - gui can start decoder (see config options). Further new gui
1052 commands: refresh (^L), jmp (F1-F10)
1053 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1054 terminates gui. This fixes dead instances consuming memory
1056 - new dbtool command: verb for sending verbatim sql queries.
1057 - fix pid_list races (by removing pid_list)
1060 --------------------
1061 0.0.97: (2003-10-26)
1062 --------------------
1064 - installation prefix now defaults to /usr/local
1065 - new commands for gui: snozze, sleep and reread config
1066 - config file for gui and sdl_gui
1067 - fix problems with filenames containing funny characters
1068 (reported by Thomas Forell)
1069 - improved signal handling for gui, now it rereads conf on SIGHUP
1070 - new dbtool command: cdb (create database)
1071 - switch from argtable to gengetopt
1072 - major code cleanup and speed improvements
1073 - fix several potential buffer overflows
1074 - many small fixes and cleanups
1080 - easy stream_defs syntax
1081 - sdl_gui can display images associated to the file being played
1082 - Major feature enhancements for icc_gui including dynamic text
1083 placement and the top/bottom window design
1084 - vrfy/clean now also checks for NULL values in attributes as
1085 well as for invalid picture pointers
1086 - fix long outstanding case sensitivity bug
1087 - many small fixes and cleanups
1093 - sdl gui runs much faster
1094 - new dbtool command: ca (copy attributes)
1095 - count and display number of times the song has been played
1096 - new feature: scoring
1097 - command line options for sdl_gui
1098 - simpler syntax of streams file
1099 - decrease network traffic of stat
1101 - many small fixes and cleanups
1107 - new server command: ns (next stream)
1108 - new icc_gui command: c (change stream)
1110 - stat shows also id3 tag info
1112 - log flodding bug fixed
1113 - many small fixes and cleanups
1119 - colors for icc_gui
1120 - icc_gui sets volume directly (linux only)
1121 - proper locking that fixes some races
1122 - fix security bug that caused commands to be executed even
1123 with unsufficient permissions
1124 - new command: hup to make all servers reread their configuration file
1125 - icecast meta data streaming
1126 - many small fixes and cleanups
