1 ---------------------------------------------
2 0.?.? (to be announced) "volatile relativity"
3 ---------------------------------------------
5 - The "versions" directory has been removed from the master
6 branch. The tarballs of the old releases are now available
7 in the new "releases" branch.
8 - Overhaul of the build system: All generated files are now
9 written to the "build" directory.
10 - The modular mixer API and the alsa mixer.
12 --------------------------------------
13 0.4.11 (2012-07-20) "mutual diversity"
14 --------------------------------------
16 The major feature in this release is the new sideband API for
17 client-server communication. This API will be used exclusively starting
18 with 0.5.0, which breaks backward compatibility but allows to get rid
19 of quite some compatibility code. Other noteworthy changes include
20 decoder latency improvements and a long-standing bug fix for the
23 - Sideband connections: If both para_server and para_client
24 support this feature, data is sent as a multiplexed stream.
25 - The --no_default_filters option of para_filter has been
27 - Several fixes and latency improvements to various decoders.
28 - The ALSA writer now limits the prebuffer time to 500ms.
29 - Documentation improvements.
30 - Overhaul of the command_util.sh script.
31 - Fixes for some minor problems found by the clang analyzer.
32 - Compiles (almost) without warnings on gcc-3.
33 - Robustness improvements of the buffer tree code.
35 ------------------------------------------
36 0.4.10 (2012-03-30) "heterogeneous vacuum"
37 ------------------------------------------
39 Nothing earth-shaking in this release, but quite a few usability
40 improvements and the usual mix of cleanups and fixes.
42 - The --no_default_filters option of para_filter has been
43 deprecated. It still works but has no effect and will be
44 removed in the next version.
45 - para_gui now prints also the stderr output of the executing
46 command in the bottom window.
47 - Cleanup and consolidation of the various wrappers for
48 write(), writev(), send() and friends.
49 - The obscure error messages on mmap() failures have been
50 replaced by meaningful messages. This affects mainly
52 - para_audioc: Cleanups and memory leak fixes.
53 - Test 0004-server no longer fails if para_server is not
55 - New configure options: --with-id3tag-{headers,libs}.
57 -------------------------------------
58 0.4.9 (2011-12-06) "hybrid causality"
59 -------------------------------------
61 Support for another audio format, interactive mode for para_client
62 and para_audiod and many small improvements/fixes all over the place.
64 - Support for flac, the free lossless audio codec.
65 - Fix for an endless loop in the mp3 decoder for certain
67 - When executed without specifying a command, para_client
68 and para_audioc start an interactive shell (requires
69 libreadline being installed). The interactive mode offers
70 full tab completion and command line history.
71 - autogen.sh now detects a distcc setup and adjusts the
72 parameter for the -j option of make accordingly.
73 - Shared memory areas are no longer restricted to 64K. We now
74 detect the maximal size of a shared memory area at runtime.
75 - cleanup of the internal uptime API.
76 - para_server prefaults the mmapped audio file to avoid
78 - A new test for the test-suite that exercises the
79 communication between para_server and para_audiod.
80 - The alsa writer eats up less CPU cycles when configured to
82 - Simplified and unified receiver code.
84 - Commands which print a list of matching audio files now
85 emit a meaningful error message if no audio file matched the
88 --------------------------------------
89 0.4.8 (2011-08-19) "nested assignment"
90 --------------------------------------
92 Gcrypt support, the overhauled osx writer and regex format specifiers
93 are the highlights of this release.
95 - support for libgcrypt as a drop-in replacement for openssl.
96 Run configure --enable-cryptolib=gcrypt to link against
97 libgcrypt. The two crypto implementations are compatible to
98 each other, i.e. a para_client executable linked against
99 gcrypt can connect to para_server linked against libssl
101 - Rewrite of the osx writer (output plugin for Mac OS).
102 - audiod: The format specifier for receivers, filters and
103 writers is now treated as a regular expression. This allows
104 to replace 5 lines in the config file (one for each audio
105 format) by one single line. See the manual for details.
106 - The *.cmdline.[ch] files are no longer contained in the released
107 tarballs. This reduces the size of the tarballs but requires
108 gengetopt to build the tarball.
109 - Compiles cleanly also with llvm/clang.
110 - Corrupt mp3 files are handled more gracefully.
111 - The alsa writer uses poll fds instead of computing timeouts.
112 - Cleanup of the generic writer API.
113 - sched: Optimized zero timeouts.
114 - vss timeout cleanups.
115 - oggdec fixes and improvements.
117 --------------------------------------
118 0.4.7 (2011-06-01) "infinite rollback"
119 --------------------------------------
121 The new ao writer, support for ssh RSA keys and a couple of other
124 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
125 platforms through the libao audio library.
126 - Support for RSA keys generated with ssh-keygen.
127 - configure: improved options for ogg/vorbis/speex.
128 - The git version reported by --version always matches HEAD.
129 - The autogen script detects the number of processors and
130 runs a parallel make if possible.
131 - Major cleanup of the crypto API.
132 - Documentation updates.
134 ------------------------------------------
135 0.4.6 (2011-03-31) "deterministic entropy"
136 ------------------------------------------
138 Lots of ogg/vorbis improvements, the new test suite, enhancements
139 for para_gui and a fair amount of other bug fixes.
141 - For DCCP/OGG streams the audio file header is only sent once
142 at the beginning of the stream rather than periodically
143 every five seconds. This reduces network traffic and the
145 - The vorbis comment header is replaced by an empty dummy header
146 before the header is sent over the network. This also results in
147 less network traffic and smaller FEC groups.
148 - The new "test" make target allows to perform some sanity checks prior
149 to installing the package.
150 - ogg timing fixes and performance improvements
151 - Scheduler improvements
152 - Proper exit codes for para_write
153 - para_gui: New option --theme to select a startup theme. Several
154 other improvements and fixes.
155 - aacdec error message cleanups
156 - simplified color error handling
158 --------------------------------------------
159 0.4.5 (2010-12-17) "symmetric randomization"
160 --------------------------------------------
162 Bug fixes, internal cleanups and variable-sized FEC slices.
164 - Contains a fix for an invalid-free-bug in the ogg audio format
166 - Switching off the DCCP sender works again.
167 - para_audiod handles crashes of para_server more robustly.
168 - Internal scheduler and writer cleanups.
169 - Reduced latency due to variable-sized FEC slices.
170 - Improved documentation and error diagnostics.
171 - The build of para_server is now optional, allowing the build
172 to succeed in case libosl is not installed.
174 ------------------------------------------
175 0.4.4 (2010-08-06) "persistent regularity"
176 ------------------------------------------
178 Support for yet another audio format, para_write improvements and
181 - Support for the speex codec.
182 - Support for sample formats other than 16 bit little endian.
183 - error2.h is now created by a perl script which speeds up configure
185 - Fix a bug in the aac decoder which could lead to segfaults in
186 para_filter/para_audiod.
187 - Fixes for autoconf-2.66.
189 ----------------------------------------
190 0.4.3 (2010-07-05) "imaginary radiation"
191 ----------------------------------------
193 Many improvements for the DCCP and the UDP transport, the new user
194 manual and the usual mix of bug fixes and internal improvements.
196 - FEC support for the DCCP sender (Gerrit Renker). The new
197 --dccp_max_slice_size, --dccp_data_slices_per_group and
198 --dccp_slices_per_group options can be used to set the FEC
199 parameters for the DCCP transport.
200 - DNS lookups for UDP targets (Gerrit Renker).
201 - The new user manual replaces the README, README.afs, REQUIREMENTS
202 and INSTALL documents.
203 - Fix an end-of-file detection bug in the oggdec filter.
204 - The new nonblock API.
205 - Both options of the oggdec filter have been removed.
206 - New debug mode for the internal scheduler.
208 ------------------------------------------
209 0.4.2 (2010-04-23) "associative expansion"
210 ------------------------------------------
212 It's been some time since the last release, but finally here is
213 paraslash-0.4.2. The bulk of the changes comes from the new buffer
214 tree API, but there are changes all over the tree. Mainly performance
215 and usability improvements, but also quite some bug fixes.
217 - The new buffer tree API.
218 - DCCP: Support for CCID negotiation (Gerrit Renker).
219 - UDP robustness fixes.
220 - The --bufsize option for mp3dec is gone as it no longer makes sense
221 for the new buffer tree API.
222 - Fix audible buffer underruns for wma streams.
223 - The alsa writer no longer prints meaningless underrun durations.
224 - audiod: Defaults work also for udp streams. If no filter is
225 given for an audio format that is received via upd, fecdec is
226 automatically added as the first filter (along with the decoder).
228 ---------------------------------------
229 0.4.1 (2009-12-22) "concurrent horizon"
230 ---------------------------------------
232 Support for another audio format, minor feature enhancements and lots of bug
233 fixes. All fixes that have been accumulated in the maint branch (in particular
234 those mentionened in the 0.3.6 release notes) appear in this release as well.
237 - new afh option: --human to activate human-readable output.
238 - new server/audiod option: --log-timing to print timing information.
239 - build system improvements.
240 - source code documentation updates.
242 -------------------------------------
243 0.3.6 (2009-12-07) "cubic continuity"
244 -------------------------------------
246 Quite a few bugs have been found and fixed since 0.3.5, so here's
247 another 0.3.x release. No new features.
249 - Always check return value of malloc().
250 - ogg vorbis/FEC: Do not write garbage after the audio file header.
251 - exit if root privileges could not be dropped.
252 - FEC: Fix computation of extra slices.
253 - oss: Fix check for empty input buffer.
254 - Avoid buffer underruns due to filter chain output buffer constraints.
255 - server: Fix assignment of afs_pid.
256 - Don't panic if the afs database contains unknown audio formats.
257 - http/dccp: Do not send the audio file header twice.
258 - FEC: Timing improvements.
260 ----------------------------------------------
261 0.4.0 (2009-11-10) "simultaneous independence"
262 ----------------------------------------------
264 Two significant changes which require the new version number: The
265 improved authentication dialog and the fact that the database code
266 has been moved to a library, libosl. To use the new version, you have
267 to generate new RSA keys, see INSTALL for details. A shell script is
268 provided for conversion of the 0.3 database to the new 0.4 format.
270 - stronger crypto for client authentication
271 - the database code has been moved to a library
272 - improved status item handling
273 - cleanup of the build system
274 - The "-V" option now also prints the git version
275 - the new parser-friendly listing mode for the ls and stat commands
276 - mandatory rc4 encryption
277 - major audio format handler cleanups
278 - (id3,...) tags are no longer stored as a combined string in the database
279 - new mood methods: artist_matches, title_matches, comment_matches,
280 album_matches, year_maches, year.
282 --------------------------------------------
283 0.3.5 (2009-09-21) "symplectic separability"
284 --------------------------------------------
286 Full client support for *BSD Unixes, complete re-write of the ogg
287 vorbis audio format handler, various improvements all over the place
288 and the usual mix of bugfixes. This release marks the end of the 0.3
289 series if no serious problems show up.
291 - the new oss writer (supported on *BSD and Linux)
292 - rewrite of the ogg vorbis audio format handler. It's
293 recommended to replace the chunk tables of existing ogg
294 vorbis files in the afs database by re-adding these files
296 - support for netmask subsets (Gerrit Renker)
297 - the new prebuffer filter
298 - improved signal handling
299 - variable fec output buffer size
300 - improved FEC timing fixes audible buffer underruns in UDP mode
301 - --log_color actually works
302 - new ls option: -d (print dates as seconds after the epoch)
303 - update to gengetopt 2.22.2
304 - support for RSA keys of size > 512 bits
305 - new option "mixer_channel" for para_fade
307 -----------------------------------------
308 0.3.4 (2009-05-07) "elliptic inheritance"
309 -----------------------------------------
311 The new udp sender, forward error correction, colored logs and various
312 other improvements. As the udp sender does not depend on any special
313 libraries, it is built unconditionally.
315 - The udp sender replaces the ortp sender. The new code uses forward
316 error correction to protect against packet losses. Many thanks to
317 Gerrit Renker for providing ipv6 support.
318 - The default port for udp streaming now defaults to 8000, like
319 for the http and the dccp senders/receivers.
320 - Loglevels are now specified as symbolic names, e.g.
322 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
323 - para_server/para_audiod: Color support for log messages.
324 - new options for mp3dec: --ignore-crc, --bufsize
325 - new audiod option: --config-file.
326 - gengetopt cleanups.
327 - Improved help/man pages: The documentation of para_audiod,
328 para_recv, para_filter and para_write now also contains
329 all options of the available receivers/filters/writers. The
330 man page of para_fade contains a description of the different
332 - More source code documentation.
335 --------------------------------------------
336 0.3.3 (2008-12-01) "axiomatic perspectivity"
337 --------------------------------------------
339 Internal code cleanups, bug fixes, improved tag handling and the new
340 amplification filter.
342 - para_server uses the generic scheduling code.
343 - overhaul of the virtual streaming system.
344 - mp3: id3 version 2 support via libid3tag (optional)
345 - ogg: vorbis comment support.
346 - aac meta info support.
347 - mp3 audio format handler cleanups.
348 - new filter: "amp" to amplify the amplitude of the audio stream
349 - new status item/database entry: amplification. It is
350 used by the amp filter to pre-amplify the audio stream.
351 - fix a close-without-open bug in para_write.
352 - fix a bug in com_init() which was introduced in 0.3.2.
353 - better error diagnostics for para_client.
355 -----------------------------------------
356 0.3.2 (2008-04-11) "probabilistic parity"
357 -----------------------------------------
359 The new para_afh executable, scheduling and documentation improvements.
361 - new ls option: -lc (list chunk table)
362 - new executable: para_afh, the stand-alone audio file handler tool
363 - afs commands can send output more than SHMMAX (32MB on Linux). This
364 also reduces the memory usage of commands that produce large amounts
366 - major scheduler and audiod cleanups.
367 - more detailed and much nicer man pages.
369 ---------------------------------------
370 0.3.1 (2008-02-23) "liquid interaction"
371 ---------------------------------------
373 A mix of cleanups, bug fixes, improvements, and some new features. No
374 significant changes to the new database (osl) code, which is generally
377 - Share some similar/duplicate code between the http and the
379 - Generic access control lists for paraslash senders.
380 - dccp sender: Access control lists, connection limiting and support
381 for the allow,deny,on,off,help sender commands.
382 - The default dccp port changed from 5001 to 8000 (suggested by
384 - para_server starts even if not all public keys could be loaded.
385 - Audiod performance improvements.
386 - fix a bug in the "off" command of the http sender.
387 - fix some fd and memory leaks.
388 - Update to gengetopt-2.22.
390 -------------------------------------
391 0.3.0 (2008-01-12) "solar saturation"
392 -------------------------------------
394 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
397 Usually one might expect lots of new features AND a big increase in size
398 for a major release like this.
400 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
401 ever. The decrease in size is mostly due to the removal of some
402 graphical tools (which were only quick hacks anyway). But also the
403 fact that the mysql code is gone cuts down the size a bit.
405 Being independent of mysql comes at a cost: The fact that paraslash
406 now contains its own database (the object storage layer, osl) increases
407 the (stripped) binary size of para_server by ~50K on i386.
409 - no more restrictions on unique basenames.
410 - independent of mysql: The new self-contained object
411 storage layer (osl) replaces the mysql database.
412 - New executable para_fsck: Check integrity of osl tables.
414 - Reliable audio file move/rename detection.
415 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
416 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
418 - the new osl-based audio file selector (afs) replaces the random,
419 the playlist and the mysql selector of paraslash-0.2.x.
420 - IPv6 support (thanks to Gerrit Renker).
421 - paraslash-0.2.x streams are now called "moods". Writing
422 0.3.x-mood definitions should be both easier and more
423 powerful than writing 0.2.x-stream definitions.
424 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
425 been removed. The world is a better place without them. However,
426 para_gui is still there.
427 - afs tracks audio file selection also in playlist mode.
428 - few easy-to-use afs commands replace the many not-so-easy-to-use
429 mysql commands (and are available also in playlist mode).
430 - Improved error subsystem.
431 - The earth-shaking new logo.
433 -----------------------------------------
434 0.2.17 (2007-11-20) "isotropic threshold"
435 -----------------------------------------
437 Mainly bugfixes and cleanups in this version which marks the end of
438 the 0.2.x series if no serious bugs show up after the release.
440 - mysql_selector: fix a locking bug.
441 - universal chunk queueing.
442 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
444 - be more carful wrt. signed vs. unsigned argument passing.
445 - cleanup error.h and fix some references to invalid error
447 - update to gengetopt-2.21.
448 - update to ortp-0.13.1.
449 - autoconf: extend checks for headers, library functions and
450 compiler characteristics.
451 - Fix streaming of large mp3 files.
452 - Fix an off-by-one bug in playlist handling.
454 --------------------------------------
455 0.2.16 (2007-04-05) "neural discharge"
456 --------------------------------------
458 The main change in this release is the major audio format handler
459 cleanup which removes some similar/duplicate code and makes it easier
460 to implement plugins for other audio formats. Of course, the usual mix
461 of other improvements/changes/bugfixes also made it into the release.
463 - simplified audio format handlers (most of the handling functions
464 were moved one layer up to the virtual streaming system).
465 - para_server uses mmap to read audio files
466 - repositioning of mp3 streams is much faster, in particular for
467 jumping near the end of large mp3 files.
468 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
470 - fix a bug in para_filter that caused decoding of aac files
471 to start only after a few seconds.
472 - fix osx_writer hangs
473 - simplified dccp code (thanks to Gerrit Renker)
474 - the compress filter works also on big endian systems (ppc)
476 -----------------------------------------
477 0.2.15 (2007-02-16) "inductive resonance"
478 -----------------------------------------
480 Minor improvements, more documentation and a bunch of bug fixes.
482 - para_server: The server.users file is only read once on server
483 startup rather than for each connection
484 - mp3dec: Fix decoding of corrupt mp3 files
485 - afs (audio file sender) is now called vss (virtual streaming
486 system). Consequently, the permission flags specified in
487 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
488 become VSS_READ and VSS_WRITE respectively.
489 - para_audiod/para_filter: Fix a bug that caused the last chunk
490 of audio data not being written under certain circumstances
491 - audiod: compute the difference of server time and local time
493 - para_server/para_audiod: Fix some memory leaks
494 - documentation improvements
495 - configure.ac: fix checks for para_krell
498 -------------------------------------------
499 0.2.14 (2006-10-15) "transient singularity"
500 -------------------------------------------
502 The only major enhancement of this version is the osx writer which completes
503 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
504 until now for reasons beyond the scope of this changelog entry.
506 - new output plugin for Mac Os: the osx writer
507 - rename configure command line options from --enable-xxx-headers to
508 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
509 - configure: new command line options: --with-mad-headers,
510 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
511 - some robustness fixes
512 - dymamic audio format recognition for audiod
513 - para_server: new command line option: --autoplay_delay
514 - para_audiod: new command line option: --clock_diff_count
516 ---------------------------------------
517 0.2.13 (2006-07-14) "sonic convolution"
518 ---------------------------------------
520 A bunch of new features and core changes.
522 - the new paraslash scheduler, short and sweet.
523 - Support for m4a/mp4 files via the new aac audio format
524 handler/filter (requires libfaad).
525 - each writer has its own command line parser, just like
526 para_recv and para_filter.
527 - para_client and para_audioc use the error subsystem
528 - writers are integrated in para_audiod (currently linux-only)
529 - para_client is integrated in para_audiod
530 - random/playlist selector: improved info strings
531 - new audiod commands: tasks, kill
532 - update to libortp-0.10.1
533 - para_fade: wake time defaults to 8 hours from now
534 - update to autoconf-2.60
536 ------------------------------------------
537 0.2.12 (2006-05-12) "oriented abstraction"
538 ------------------------------------------
540 Many user-visible changes in this release and lots of new
544 - the new optional dccp sender/receiver. It uses the datagram
545 congestion control protocol. You'll need a fairly new kernel
547 - paraslash works on Mac OS X (thanks to Gerd Becker)
548 - para_play renamed to para_write
549 - modular output plugin design (writers) for para_write
550 - new file_writer output plugin for para_write
551 - compress filter speed improvements
552 - update to libortp-0.9.1
553 - update to gengetopt-2.17rc
554 - para_client no longer depends on libreadline (as the
555 code for the interactive mode was removed).
556 - gcc-2-95 is no longer a supported compiler. It may still
557 work, but it gets no more testing.
558 - the tarball no longer contains the screenshot images which
559 reduces its size quite a bit.
560 - configure: new command line options: --enable-mysql-headers
561 and --enable-mysql-libs
563 ------------------------------------
564 0.2.11 (2006-03-11) "atomic duality"
565 ------------------------------------
567 Here it is, the first paraslash release developed with git. There
568 are fairly many user-visible changes in this release. As two out of
569 the three "database tools" of paraslash don't use a database at all,
570 they are now called "audio file selectors" instead.
573 - the cdt command (change database tool) becomes chs (change
575 - no more colon separators: The syntax of some options of
576 para_audiod and para_filter have changed. Use --help for
577 more info (and some examples).
578 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
579 - switch from cvs to git (should've done that earlier)
580 - the new ipc subsystem
581 - new audio file selector: playlist
582 - para_server: the dopey selector is now called "random",
583 and is the default selector. Use the --selector option to
584 choose another selector at startup, or the chs command to
585 change the selector at runtime.
586 - X86_64 fixes (thanks to Steffen Klassert)
589 --------------------------------------
590 0.2.10 (2006-02-17) "cyclic attractor"
591 --------------------------------------
593 Huge documentation update, a scrollable window for para_gui, ortp
594 improvements, and of course many small fixes not mentioned here.
595 The diffstat below is rather misleading as most insertions are due
596 to the new source documentation.
599 - para_server also uses the new error subsystem
600 - lots of new documentation (UTSL)
602 - keysyms for cursor keys and for next/previous page keys
603 - scrollable output window
604 - new internal commands: scroll up/down, page up/down
605 - fix color of command output.
606 - ortp: the --chunk_time and --header flags are no longer needed
607 for para_recv/para_audiod as this information is now encoded in
608 each rtp packet sent by para_server.
610 -------------------------------------------
611 0.2.9 (2006-01-24) "progressive turbulence"
612 -------------------------------------------
614 Internal audiod receivers/filters, the new error subsystem and
615 a lot of small improvements.
617 - para_recv and para_filter are integrated into the para_audiod
618 binary, i.e. audiod no longer spawns a new process for
619 each receiver/filter. As para_recv and para_filter might be
620 useful as standalone programs, they still get built (linked
621 against the same object files that are also used for audiod).
622 - further ortp timing improvements should reduce the CPU usage
623 of the ortp receiver.
624 - improved audio grabbing. The 'grab' command of para_audiod
625 has its own set of command line options. Read the output of
626 "para_audioc help grab" for more info.
627 - oggdec: configurable input prebuffer size.
628 - the new error subsystem gives better error diagnostics
629 and reduces code size.
631 -----------------------------------------
632 0.2.8 (2006-01-02) "dynamic accumulation"
633 -----------------------------------------
635 The new modular filter design and the para_play-hangs bugfix.
637 - new executable: para_filter. It combines para_mp3dec,
638 para_oggdec and para_compress. It also adds a further filter
639 type, wav, that just inserts a wave header at the desired point
640 of the filter chain. All 'piping' is done in-memory (i.e. no
641 read/write operations are used).
642 - para_play: fix a stupid bug that caused it to hang under
643 certain circumstances.
645 -------------------------------------------
646 0.2.7 (2006-12-27) "transparent invariance"
647 -------------------------------------------
649 Not many user-visible changes but a fair amount of internal improvements.
652 - The http sender buffers data if it can not be sent
653 out immediately (because the socket is not writable). This
654 should prevent para_server from shutting down the connection
655 too early on a loaded network.
656 - para_play also prebuffers data if it is told to start at a
657 future time by the --start_time option.
658 - The return of para_recv: It combines para_ortp_recv and
659 para_http_recv. Use the --receiver option to switch between
660 the two. para_recv builds without libortp, but contains
661 only the http receiver in this case.
662 - update to ortp 0.8.1. As this ortp release contains incompatible
663 changes, para_recv-0.2.7 won't link against older ortp libs.
664 - improved ortp timings.
665 - use of gcc-extensions that #define away for non-gcc and
668 -------------------------------------------
669 0.2.6 (2005-10-29) "recursive compensation"
670 -------------------------------------------
672 Transparent session encryption (uses openssl's Alleged RC4 cipher),
673 the internal find command and several other improvements and cleanups.
675 - Encrypt the session if encryption is requested by the client
676 (default for para_client 0.2.6). This is backwards
677 compatible, so older clients can still connect to para_server
678 0.2.6. Use the new client option --plain to request an
679 uncrypted session (off by default, must be set to on in
680 order to connect to para_server 0.2.x with 0 <= x <= 5).
681 - para_server uses an internal function to locate audio files
682 rather than calling find(1). The server option
683 --mysql_audio_file_dir replaces --mysql_find_cmd.
684 - documentation update
686 - header file cleanup
687 - para_client code cleanup
688 - para_gui: faster display of output of display commands
690 ------------------------------------------
691 0.2.5 (2005-10-13) "aggressive resolution"
692 ------------------------------------------
694 This release adds internal senders, i.e. no more external programs are
695 spawned for sending out the audio data. There are two different senders
696 available: The http sender and the ortp sender (former para_send which
697 is no longer needed).
699 The new sender code has a plugin-like design so it can be easily
700 extended should there be be any future need for supporting another
701 network streaming protocol. All senders are completely independent of
702 each other. In particular, the http and the ortp sender can operate
705 - new server command: sender to control senders at runtime.
706 Read the output of "para_server -h" and "para_client help
707 sender" for more information.
708 - para_recv renamed to para_ortp_recv
709 - new executable: para_http_recv, a simple command line
711 - major afs/mp3/ogg code simplifications due to internal
713 - ogg timing improvements
714 - fix several minor memory leaks (found by valgrind)
715 - empty stream definitions work again
716 - com_ne(): ignore errors on remove
717 - audiod: fix segfault on server restart
719 ---------------------------------------
720 0.2.4 (2005-09-21) "toxic anticipation"
721 ---------------------------------------
723 Several small improvements, fixes and the new grab command.
726 - new command: "grab" to grab the output of the stream reader
727 or any filters. Read the output of "para_audioc help grab"
728 for more information.
731 - audioc: new command line option: --bufsize to specify a
732 buffer size different from the default size 8192.
733 - improved error diagnostics for para_play.
734 - new configure option: --enable-ssldir so search for openssl in
736 - sdl_gui: Make it look nice again for 1024x768
737 - server: report total size of memory allocated with sbrk by malloc,
738 new command line option: --announce_time
740 -----------------------------------------
741 0.2.3 (2005-09-01) "hydrophilic movement"
742 -----------------------------------------
744 Two new executables and major feature enhancements.
746 - audiod filters: It is now possible to specify arbitrary many
747 (including none) filters for each supported audio
748 format. This can be used e.g. for normalizing volume,
749 transforming or grabbing the audio stream, or for using
750 visualizers. Read the output of "para_audiod -h" for the
751 syntax of the new --filter_cmd option.
752 - new executable: para_play, a tiny alsa player. It
753 can play wave files or raw pcm (16 bit little endian)
755 - new executable: para_compress, a dynamic range compressor
756 intended to keep audio output at a consistent volume. Derived
757 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
758 - audiod: New option: --stream_delay. This can be used in
759 a local network to syncronize the audio output of all
760 clients that play the same stream.
762 ------------------------------------------
763 0.2.2 (2005-08-19) "tangential excitation"
764 ------------------------------------------
766 Mostly internal changes in this release, but also some new commands
767 for the mysql database tool.
769 - cleanup exec.c, fix para_exec bug
770 - compile time loglevel (log messages below the given level
771 won't be compiled in, which reduces the size of the
773 - new log macros that shorten the size of the source code.
774 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
775 to send only zeros. With this workaround, para_audioc works
777 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
778 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
779 (new entry), "snp" (set numplayed). Read the manual for more
782 ---------------------------------------
783 0.2.1 (2005-08-15) "surreal experience"
784 ---------------------------------------
786 Here comes paraslash-0.2.1. It contains a couple of new features and,
787 surprise, only minor bug fixes.
789 - kill noisy mp3 debug message
790 - cleanup of the build system
791 - para_server and para_client directly use the crypto routines
792 of the openssl library rather than invoking the openssl command
794 - server/audiod: new option --user to switch to the given user
795 when invoked as root. Read the output of "para_server -h" for
797 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
798 status. Default: "para_audioc stat"
799 - sdl_gui: new option --pic_cmd to be used to download the picture.
800 Default: "para_client pic"
801 - audiod: 5 slots ought to be enough for everybody
802 - audiod: new status item: Uptime, kill hup command
804 ------------------------------------------
805 0.2.0 (2005-08-06) "distributed diffusion"
806 ------------------------------------------
808 After several month of increased development activity, paraslash-0.2.0
809 has arrived. It contains many new features and is much more
810 self-contained than the old 0.1.x series. Enjoy!
813 - para_server: fix hang on song change and crash on sighup.
814 Speed up mysql queries. The DIR_LIKE macro is gone.
815 - new executables: para_audiod, the local audio daemon that
816 starts playback (uses SCM_CREDENTIALS socket magic) and
817 para_audioc, the corresponding client.
818 - new executables: para_mp3dec/para_oggdec, two really teensy
819 decoders. para_mp3dec is based on libmad, para_oggdec requires
821 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
822 they are now called para_send and para_recv respectively.
823 - documentation updates
824 - para_gui is themable. For now there is the default theme that
825 looks as before and the simple theme: blue and easy.
826 - gui: audio streaming is now handled by audiod. Time display shows
827 playback time rather than streaming time
828 - slider: update to libzmw-0.2.0
829 - para_krell: fix crash on server shutdown
830 - switch from gzip to bzip2
832 ----------------------------------------
833 0.1.7 (2005-04-18) "melting penetration"
834 ----------------------------------------
836 The main change in this release is clearly the oggvorbis rewrite,
837 but there are also lots of smaller changes. If you intend to use both
838 the mp3 and the ogg plugin, it is recommended to use software mixing,
839 e.g. the dmix plugin which is provided by ALSA.
841 - new executables: para_ovsend and para_ovrecv for sending/receiving
842 oggvorbis files via rtp. Requires the open rtp library. Get it at
843 http://www.linphone.org/ortp/
844 - rewrite of the ogg_vorbis core code
845 - configure detects libzmw and, if detected, includes
846 para_slider to the list of binaries to be built by make
847 - server stream writers read from their associated fifo rather
849 - slider: two new sliders, lastplayed and numplayed
850 - fix nasty double free bug which caused random segfaults in case of
851 mp3 files with invalid header information
852 - gui: new command line option: --stream_timeout=seconds to
853 deactivate a slot if it is idle for that many seconds (default=`5')
856 ---------------------------------------
857 0.1.6 (2005-03-05) "asymptotic balance"
858 ---------------------------------------
860 Only little user-visible changes in this release. Mainly bugfixes and
861 core code cleanup. This is probably the most stable version ever if you
864 - fix several memory leaks
865 - rename default name of mysql database from "music" to "paraslash".
866 Use para_server's --mysql_database option if you do not want to
867 rename your old database.
868 - rework ogg vorbis code
869 - make update command work on mysql servers with LOCAL_INFILE
871 - gui: improved stream I/O (slots)
872 - simplified audio format API
873 - para_pob_ogg is gone
875 ------------------------------------
876 0.1.5 (2004-12-31) "opaque eternity"
877 ------------------------------------
879 Let's slide gently into the new year.
881 - new: para_slider (not built automatically, type "make
882 para_slider" to build). A toy for those who always felt that
883 creating stream definitions is difficult. See screenshots,
884 README and FEATURES for more info.
885 - improved signal handling. Fixes server segfault on SIGHUP
886 for linux kernels newer than Aug 24 2004 and makes para_gui
888 - reload database tool on SIGHUP
889 - improved help message for sl
890 - do not log "broken pipe" messages as errors. They are
892 - fix wrong error message on permission errors
894 -----------------------------------------
895 0.1.4 (2004-12-19) "tunneling transition"
896 -----------------------------------------
898 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
899 Hopefully, most of them got wiped out with this release. Some
900 enhancements went also in.
902 - improved error diagnostics for all commands
903 - stradd/picadd: overwrite previous contents if entry already
904 exists, rather than returning errors
905 - stradd: use current stream if invoked without args
906 - faster (and hopefully more stable) ogg-vorbis handling
907 - para_krell: reap children to avoid zombie-flooding in case
909 - si: report also server pid
910 - server: don't busy-loop if dbtool reports only invalid files.
911 - gui: CTRL+C works again, fix stream_read command line option
913 - fix mysql dbtool startup in case no database exists
914 - many small fixes and cleanups
916 ---------------------------------------
917 0.1.3: (2004-12-10) "vanishing inertia"
918 ---------------------------------------
920 Starting from this release, the database tools are integrated in the
921 server binary. This decreases server startup time, reduces code size
922 and speeds up database commands. However, the layout of the underlying
923 mysql database changed only slightly and 0.1.3 should be backwards
924 compatible in that respect.
928 - If mysql is not detected at compile time, or fails to init
929 at runtime, fall back to the dopey database tool which should
931 - para_dbtool and dbtool.conf are gone. All mysql specific
932 options are read from server.conf and are prefixed by 'mysql_'.
933 - new command: cdt (change database tool)
934 - new command line option: dbtool (choose startup database tool)
935 - The name of current stream is now stored in the database,
936 so paraslash remembers its current stream when restarted.
937 - new command: csp (change stream and play)
938 - para_gui also reports current database tool and server uptime
940 -------------------------------------------
941 0.1.2: (2004-11-28) "spherical fluctuation"
942 -------------------------------------------
944 Point release before the big dbtool changes go in.
946 - dbtool: rename ca to cam (copy all meta data). It now also
947 copies numplayed and lastplayed time as well as the picture
949 - fix endless-loop-bug caused by mp3 files with invalid header
951 -----------------------------------------
952 0.1.1: (2004-11-05) "floating atmosphere"
953 -----------------------------------------
956 - new dbtool command: mbox. Browse your sound-file collection
957 with your favorite mail reader.
958 - several small fixes
960 -------------------------------------
961 0.1.0: (2004-10-22) "rotating cortex"
962 -------------------------------------
964 - fix logging bug for loglevel > VERBOSE
966 - correct timings for vbr mp3s
967 - modular audio format support
968 - ogg-vorbis support (experimental)
969 - new server option: autoplay
971 -----------------------------------------
972 0.0.99: (2004-07-25) "harmonic deviation"
973 -----------------------------------------
975 - rename projectname from icc to paraslash (play, archive, rate
976 and stream large audio sets happily)
977 - paraslash is no longer restricted to one particular audio
979 - new dbtool commands (stradd, strq, strdel) for easy stream
980 managment w/o configuration file. That obsoletes stream_defs
981 file/config option for dbtool.
982 - picadd accepts jpeg data from stdin
983 - new server commands: ps (select previous stream), sc (song change)
984 - new default pictures for sdl_gui
985 - gui: new key_map option for binding commands and internal
986 functions to arbitrary keys, nice help screen, rip out
987 soundcard/linux specific stuff, avoid noise artefacts while jumping,
988 show silly logo on startup
989 - new executables: para_fade for fading volume, para_dbadm for
990 manipulating attributes
991 - cdb adds _all_ tables to mysql database
992 - revised and beautified documentation
993 - sample dbtool rewritten in C
996 ---------------------------------------------
997 0.0.98: (2003-12-26) "incremental smoothness"
998 ---------------------------------------------
1000 - kick icecast in favour of poc. That removes some races and reduces
1001 core code considerably.
1002 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1003 give finer info on afs' status.
1004 - gui can start decoder (see config options). Further new gui
1005 commands: refresh (^L), jmp (F1-F10)
1006 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1007 terminates gui. This fixes dead instances consuming memory
1009 - new dbtool command: verb for sending verbatim sql queries.
1010 - fix pid_list races (by removing pid_list)
1013 --------------------
1014 0.0.97: (2003-10-26)
1015 --------------------
1017 - installation prefix now defaults to /usr/local
1018 - new commands for gui: snozze, sleep and reread config
1019 - config file for gui and sdl_gui
1020 - fix problems with filenames containing funny characters
1021 (reported by Thomas Forell)
1022 - improved signal handling for gui, now it rereads conf on SIGHUP
1023 - new dbtool command: cdb (create database)
1024 - switch from argtable to gengetopt
1025 - major code cleanup and speed improvements
1026 - fix several potential buffer overflows
1027 - many small fixes and cleanups
1033 - easy stream_defs syntax
1034 - sdl_gui can display images associated to the file being played
1035 - Major feature enhancements for icc_gui including dynamic text
1036 placement and the top/bottom window design
1037 - vrfy/clean now also checks for NULL values in attributes as
1038 well as for invalid picture pointers
1039 - fix long outstanding case sensitivity bug
1040 - many small fixes and cleanups
1046 - sdl gui runs much faster
1047 - new dbtool command: ca (copy attributes)
1048 - count and display number of times the song has been played
1049 - new feature: scoring
1050 - command line options for sdl_gui
1051 - simpler syntax of streams file
1052 - decrease network traffic of stat
1054 - many small fixes and cleanups
1060 - new server command: ns (next stream)
1061 - new icc_gui command: c (change stream)
1063 - stat shows also id3 tag info
1065 - log flodding bug fixed
1066 - many small fixes and cleanups
1072 - colors for icc_gui
1073 - icc_gui sets volume directly (linux only)
1074 - proper locking that fixes some races
1075 - fix security bug that caused commands to be executed even
1076 with unsufficient permissions
1077 - new command: hup to make all servers reread their configuration file
1078 - icecast meta data streaming
1079 - many small fixes and cleanups
