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.
9 --------------------------------------
10 0.4.11 (2012-07-20) "mutual diversity"
11 --------------------------------------
13 The major feature in this release is the new sideband API for
14 client-server communication. This API will be used exclusively starting
15 with 0.5.0, which breaks backward compatibility but allows to get rid
16 of quite some compatibility code. Other noteworthy changes include
17 decoder latency improvements and a long-standing bug fix for the
20 - Sideband connections: If both para_server and para_client
21 support this feature, data is sent as a multiplexed stream.
22 - The --no_default_filters option of para_filter has been
24 - Several fixes and latency improvements to various decoders.
25 - The ALSA writer now limits the prebuffer time to 500ms.
26 - Documentation improvements.
27 - Overhaul of the command_util.sh script.
28 - Fixes for some minor problems found by the clang analyzer.
29 - Compiles (almost) without warnings on gcc-3.
30 - Robustness improvements of the buffer tree code.
32 ------------------------------------------
33 0.4.10 (2012-03-30) "heterogeneous vacuum"
34 ------------------------------------------
36 Nothing earth-shaking in this release, but quite a few usability
37 improvements and the usual mix of cleanups and fixes.
39 - The --no_default_filters option of para_filter has been
40 deprecated. It still works but has no effect and will be
41 removed in the next version.
42 - para_gui now prints also the stderr output of the executing
43 command in the bottom window.
44 - Cleanup and consolidation of the various wrappers for
45 write(), writev(), send() and friends.
46 - The obscure error messages on mmap() failures have been
47 replaced by meaningful messages. This affects mainly
49 - para_audioc: Cleanups and memory leak fixes.
50 - Test 0004-server no longer fails if para_server is not
52 - New configure options: --with-id3tag-{headers,libs}.
54 -------------------------------------
55 0.4.9 (2011-12-06) "hybrid causality"
56 -------------------------------------
58 Support for another audio format, interactive mode for para_client
59 and para_audiod and many small improvements/fixes all over the place.
61 - Support for flac, the free lossless audio codec.
62 - Fix for an endless loop in the mp3 decoder for certain
64 - When executed without specifying a command, para_client
65 and para_audioc start an interactive shell (requires
66 libreadline being installed). The interactive mode offers
67 full tab completion and command line history.
68 - autogen.sh now detects a distcc setup and adjusts the
69 parameter for the -j option of make accordingly.
70 - Shared memory areas are no longer restricted to 64K. We now
71 detect the maximal size of a shared memory area at runtime.
72 - cleanup of the internal uptime API.
73 - para_server prefaults the mmapped audio file to avoid
75 - A new test for the test-suite that exercises the
76 communication between para_server and para_audiod.
77 - The alsa writer eats up less CPU cycles when configured to
79 - Simplified and unified receiver code.
81 - Commands which print a list of matching audio files now
82 emit a meaningful error message if no audio file matched the
85 --------------------------------------
86 0.4.8 (2011-08-19) "nested assignment"
87 --------------------------------------
89 Gcrypt support, the overhauled osx writer and regex format specifiers
90 are the highlights of this release.
92 - support for libgcrypt as a drop-in replacement for openssl.
93 Run configure --enable-cryptolib=gcrypt to link against
94 libgcrypt. The two crypto implementations are compatible to
95 each other, i.e. a para_client executable linked against
96 gcrypt can connect to para_server linked against libssl
98 - Rewrite of the osx writer (output plugin for Mac OS).
99 - audiod: The format specifier for receivers, filters and
100 writers is now treated as a regular expression. This allows
101 to replace 5 lines in the config file (one for each audio
102 format) by one single line. See the manual for details.
103 - The *.cmdline.[ch] files are no longer contained in the released
104 tarballs. This reduces the size of the tarballs but requires
105 gengetopt to build the tarball.
106 - Compiles cleanly also with llvm/clang.
107 - Corrupt mp3 files are handled more gracefully.
108 - The alsa writer uses poll fds instead of computing timeouts.
109 - Cleanup of the generic writer API.
110 - sched: Optimized zero timeouts.
111 - vss timeout cleanups.
112 - oggdec fixes and improvements.
114 --------------------------------------
115 0.4.7 (2011-06-01) "infinite rollback"
116 --------------------------------------
118 The new ao writer, support for ssh RSA keys and a couple of other
121 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
122 platforms through the libao audio library.
123 - Support for RSA keys generated with ssh-keygen.
124 - configure: improved options for ogg/vorbis/speex.
125 - The git version reported by --version always matches HEAD.
126 - The autogen script detects the number of processors and
127 runs a parallel make if possible.
128 - Major cleanup of the crypto API.
129 - Documentation updates.
131 ------------------------------------------
132 0.4.6 (2011-03-31) "deterministic entropy"
133 ------------------------------------------
135 Lots of ogg/vorbis improvements, the new test suite, enhancements
136 for para_gui and a fair amount of other bug fixes.
138 - For DCCP/OGG streams the audio file header is only sent once
139 at the beginning of the stream rather than periodically
140 every five seconds. This reduces network traffic and the
142 - The vorbis comment header is replaced by an empty dummy header
143 before the header is sent over the network. This also results in
144 less network traffic and smaller FEC groups.
145 - The new "test" make target allows to perform some sanity checks prior
146 to installing the package.
147 - ogg timing fixes and performance improvements
148 - Scheduler improvements
149 - Proper exit codes for para_write
150 - para_gui: New option --theme to select a startup theme. Several
151 other improvements and fixes.
152 - aacdec error message cleanups
153 - simplified color error handling
155 --------------------------------------------
156 0.4.5 (2010-12-17) "symmetric randomization"
157 --------------------------------------------
159 Bug fixes, internal cleanups and variable-sized FEC slices.
161 - Contains a fix for an invalid-free-bug in the ogg audio format
163 - Switching off the DCCP sender works again.
164 - para_audiod handles crashes of para_server more robustly.
165 - Internal scheduler and writer cleanups.
166 - Reduced latency due to variable-sized FEC slices.
167 - Improved documentation and error diagnostics.
168 - The build of para_server is now optional, allowing the build
169 to succeed in case libosl is not installed.
171 ------------------------------------------
172 0.4.4 (2010-08-06) "persistent regularity"
173 ------------------------------------------
175 Support for yet another audio format, para_write improvements and
178 - Support for the speex codec.
179 - Support for sample formats other than 16 bit little endian.
180 - error2.h is now created by a perl script which speeds up configure
182 - Fix a bug in the aac decoder which could lead to segfaults in
183 para_filter/para_audiod.
184 - Fixes for autoconf-2.66.
186 ----------------------------------------
187 0.4.3 (2010-07-05) "imaginary radiation"
188 ----------------------------------------
190 Many improvements for the DCCP and the UDP transport, the new user
191 manual and the usual mix of bug fixes and internal improvements.
193 - FEC support for the DCCP sender (Gerrit Renker). The new
194 --dccp_max_slice_size, --dccp_data_slices_per_group and
195 --dccp_slices_per_group options can be used to set the FEC
196 parameters for the DCCP transport.
197 - DNS lookups for UDP targets (Gerrit Renker).
198 - The new user manual replaces the README, README.afs, REQUIREMENTS
199 and INSTALL documents.
200 - Fix an end-of-file detection bug in the oggdec filter.
201 - The new nonblock API.
202 - Both options of the oggdec filter have been removed.
203 - New debug mode for the internal scheduler.
205 ------------------------------------------
206 0.4.2 (2010-04-23) "associative expansion"
207 ------------------------------------------
209 It's been some time since the last release, but finally here is
210 paraslash-0.4.2. The bulk of the changes comes from the new buffer
211 tree API, but there are changes all over the tree. Mainly performance
212 and usability improvements, but also quite some bug fixes.
214 - The new buffer tree API.
215 - DCCP: Support for CCID negotiation (Gerrit Renker).
216 - UDP robustness fixes.
217 - The --bufsize option for mp3dec is gone as it no longer makes sense
218 for the new buffer tree API.
219 - Fix audible buffer underruns for wma streams.
220 - The alsa writer no longer prints meaningless underrun durations.
221 - audiod: Defaults work also for udp streams. If no filter is
222 given for an audio format that is received via upd, fecdec is
223 automatically added as the first filter (along with the decoder).
225 ---------------------------------------
226 0.4.1 (2009-12-22) "concurrent horizon"
227 ---------------------------------------
229 Support for another audio format, minor feature enhancements and lots of bug
230 fixes. All fixes that have been accumulated in the maint branch (in particular
231 those mentionened in the 0.3.6 release notes) appear in this release as well.
234 - new afh option: --human to activate human-readable output.
235 - new server/audiod option: --log-timing to print timing information.
236 - build system improvements.
237 - source code documentation updates.
239 -------------------------------------
240 0.3.6 (2009-12-07) "cubic continuity"
241 -------------------------------------
243 Quite a few bugs have been found and fixed since 0.3.5, so here's
244 another 0.3.x release. No new features.
246 - Always check return value of malloc().
247 - ogg vorbis/FEC: Do not write garbage after the audio file header.
248 - exit if root privileges could not be dropped.
249 - FEC: Fix computation of extra slices.
250 - oss: Fix check for empty input buffer.
251 - Avoid buffer underruns due to filter chain output buffer constraints.
252 - server: Fix assignment of afs_pid.
253 - Don't panic if the afs database contains unknown audio formats.
254 - http/dccp: Do not send the audio file header twice.
255 - FEC: Timing improvements.
257 ----------------------------------------------
258 0.4.0 (2009-11-10) "simultaneous independence"
259 ----------------------------------------------
261 Two significant changes which require the new version number: The
262 improved authentication dialog and the fact that the database code
263 has been moved to a library, libosl. To use the new version, you have
264 to generate new RSA keys, see INSTALL for details. A shell script is
265 provided for conversion of the 0.3 database to the new 0.4 format.
267 - stronger crypto for client authentication
268 - the database code has been moved to a library
269 - improved status item handling
270 - cleanup of the build system
271 - The "-V" option now also prints the git version
272 - the new parser-friendly listing mode for the ls and stat commands
273 - mandatory rc4 encryption
274 - major audio format handler cleanups
275 - (id3,...) tags are no longer stored as a combined string in the database
276 - new mood methods: artist_matches, title_matches, comment_matches,
277 album_matches, year_maches, year.
279 --------------------------------------------
280 0.3.5 (2009-09-21) "symplectic separability"
281 --------------------------------------------
283 Full client support for *BSD Unixes, complete re-write of the ogg
284 vorbis audio format handler, various improvements all over the place
285 and the usual mix of bugfixes. This release marks the end of the 0.3
286 series if no serious problems show up.
288 - the new oss writer (supported on *BSD and Linux)
289 - rewrite of the ogg vorbis audio format handler. It's
290 recommended to replace the chunk tables of existing ogg
291 vorbis files in the afs database by re-adding these files
293 - support for netmask subsets (Gerrit Renker)
294 - the new prebuffer filter
295 - improved signal handling
296 - variable fec output buffer size
297 - improved FEC timing fixes audible buffer underruns in UDP mode
298 - --log_color actually works
299 - new ls option: -d (print dates as seconds after the epoch)
300 - update to gengetopt 2.22.2
301 - support for RSA keys of size > 512 bits
302 - new option "mixer_channel" for para_fade
304 -----------------------------------------
305 0.3.4 (2009-05-07) "elliptic inheritance"
306 -----------------------------------------
308 The new udp sender, forward error correction, colored logs and various
309 other improvements. As the udp sender does not depend on any special
310 libraries, it is built unconditionally.
312 - The udp sender replaces the ortp sender. The new code uses forward
313 error correction to protect against packet losses. Many thanks to
314 Gerrit Renker for providing ipv6 support.
315 - The default port for udp streaming now defaults to 8000, like
316 for the http and the dccp senders/receivers.
317 - Loglevels are now specified as symbolic names, e.g.
319 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
320 - para_server/para_audiod: Color support for log messages.
321 - new options for mp3dec: --ignore-crc, --bufsize
322 - new audiod option: --config-file.
323 - gengetopt cleanups.
324 - Improved help/man pages: The documentation of para_audiod,
325 para_recv, para_filter and para_write now also contains
326 all options of the available receivers/filters/writers. The
327 man page of para_fade contains a description of the different
329 - More source code documentation.
332 --------------------------------------------
333 0.3.3 (2008-12-01) "axiomatic perspectivity"
334 --------------------------------------------
336 Internal code cleanups, bug fixes, improved tag handling and the new
337 amplification filter.
339 - para_server uses the generic scheduling code.
340 - overhaul of the virtual streaming system.
341 - mp3: id3 version 2 support via libid3tag (optional)
342 - ogg: vorbis comment support.
343 - aac meta info support.
344 - mp3 audio format handler cleanups.
345 - new filter: "amp" to amplify the amplitude of the audio stream
346 - new status item/database entry: amplification. It is
347 used by the amp filter to pre-amplify the audio stream.
348 - fix a close-without-open bug in para_write.
349 - fix a bug in com_init() which was introduced in 0.3.2.
350 - better error diagnostics for para_client.
352 -----------------------------------------
353 0.3.2 (2008-04-11) "probabilistic parity"
354 -----------------------------------------
356 The new para_afh executable, scheduling and documentation improvements.
358 - new ls option: -lc (list chunk table)
359 - new executable: para_afh, the stand-alone audio file handler tool
360 - afs commands can send output more than SHMMAX (32MB on Linux). This
361 also reduces the memory usage of commands that produce large amounts
363 - major scheduler and audiod cleanups.
364 - more detailed and much nicer man pages.
366 ---------------------------------------
367 0.3.1 (2008-02-23) "liquid interaction"
368 ---------------------------------------
370 A mix of cleanups, bug fixes, improvements, and some new features. No
371 significant changes to the new database (osl) code, which is generally
374 - Share some similar/duplicate code between the http and the
376 - Generic access control lists for paraslash senders.
377 - dccp sender: Access control lists, connection limiting and support
378 for the allow,deny,on,off,help sender commands.
379 - The default dccp port changed from 5001 to 8000 (suggested by
381 - para_server starts even if not all public keys could be loaded.
382 - Audiod performance improvements.
383 - fix a bug in the "off" command of the http sender.
384 - fix some fd and memory leaks.
385 - Update to gengetopt-2.22.
387 -------------------------------------
388 0.3.0 (2008-01-12) "solar saturation"
389 -------------------------------------
391 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
394 Usually one might expect lots of new features AND a big increase in size
395 for a major release like this.
397 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
398 ever. The decrease in size is mostly due to the removal of some
399 graphical tools (which were only quick hacks anyway). But also the
400 fact that the mysql code is gone cuts down the size a bit.
402 Being independent of mysql comes at a cost: The fact that paraslash
403 now contains its own database (the object storage layer, osl) increases
404 the (stripped) binary size of para_server by ~50K on i386.
406 - no more restrictions on unique basenames.
407 - independent of mysql: The new self-contained object
408 storage layer (osl) replaces the mysql database.
409 - New executable para_fsck: Check integrity of osl tables.
411 - Reliable audio file move/rename detection.
412 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
413 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
415 - the new osl-based audio file selector (afs) replaces the random,
416 the playlist and the mysql selector of paraslash-0.2.x.
417 - IPv6 support (thanks to Gerrit Renker).
418 - paraslash-0.2.x streams are now called "moods". Writing
419 0.3.x-mood definitions should be both easier and more
420 powerful than writing 0.2.x-stream definitions.
421 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
422 been removed. The world is a better place without them. However,
423 para_gui is still there.
424 - afs tracks audio file selection also in playlist mode.
425 - few easy-to-use afs commands replace the many not-so-easy-to-use
426 mysql commands (and are available also in playlist mode).
427 - Improved error subsystem.
428 - The earth-shaking new logo.
430 -----------------------------------------
431 0.2.17 (2007-11-20) "isotropic threshold"
432 -----------------------------------------
434 Mainly bugfixes and cleanups in this version which marks the end of
435 the 0.2.x series if no serious bugs show up after the release.
437 - mysql_selector: fix a locking bug.
438 - universal chunk queueing.
439 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
441 - be more carful wrt. signed vs. unsigned argument passing.
442 - cleanup error.h and fix some references to invalid error
444 - update to gengetopt-2.21.
445 - update to ortp-0.13.1.
446 - autoconf: extend checks for headers, library functions and
447 compiler characteristics.
448 - Fix streaming of large mp3 files.
449 - Fix an off-by-one bug in playlist handling.
451 --------------------------------------
452 0.2.16 (2007-04-05) "neural discharge"
453 --------------------------------------
455 The main change in this release is the major audio format handler
456 cleanup which removes some similar/duplicate code and makes it easier
457 to implement plugins for other audio formats. Of course, the usual mix
458 of other improvements/changes/bugfixes also made it into the release.
460 - simplified audio format handlers (most of the handling functions
461 were moved one layer up to the virtual streaming system).
462 - para_server uses mmap to read audio files
463 - repositioning of mp3 streams is much faster, in particular for
464 jumping near the end of large mp3 files.
465 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
467 - fix a bug in para_filter that caused decoding of aac files
468 to start only after a few seconds.
469 - fix osx_writer hangs
470 - simplified dccp code (thanks to Gerrit Renker)
471 - the compress filter works also on big endian systems (ppc)
473 -----------------------------------------
474 0.2.15 (2007-02-16) "inductive resonance"
475 -----------------------------------------
477 Minor improvements, more documentation and a bunch of bug fixes.
479 - para_server: The server.users file is only read once on server
480 startup rather than for each connection
481 - mp3dec: Fix decoding of corrupt mp3 files
482 - afs (audio file sender) is now called vss (virtual streaming
483 system). Consequently, the permission flags specified in
484 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
485 become VSS_READ and VSS_WRITE respectively.
486 - para_audiod/para_filter: Fix a bug that caused the last chunk
487 of audio data not being written under certain circumstances
488 - audiod: compute the difference of server time and local time
490 - para_server/para_audiod: Fix some memory leaks
491 - documentation improvements
492 - configure.ac: fix checks for para_krell
495 -------------------------------------------
496 0.2.14 (2006-10-15) "transient singularity"
497 -------------------------------------------
499 The only major enhancement of this version is the osx writer which completes
500 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
501 until now for reasons beyond the scope of this changelog entry.
503 - new output plugin for Mac Os: the osx writer
504 - rename configure command line options from --enable-xxx-headers to
505 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
506 - configure: new command line options: --with-mad-headers,
507 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
508 - some robustness fixes
509 - dymamic audio format recognition for audiod
510 - para_server: new command line option: --autoplay_delay
511 - para_audiod: new command line option: --clock_diff_count
513 ---------------------------------------
514 0.2.13 (2006-07-14) "sonic convolution"
515 ---------------------------------------
517 A bunch of new features and core changes.
519 - the new paraslash scheduler, short and sweet.
520 - Support for m4a/mp4 files via the new aac audio format
521 handler/filter (requires libfaad).
522 - each writer has its own command line parser, just like
523 para_recv and para_filter.
524 - para_client and para_audioc use the error subsystem
525 - writers are integrated in para_audiod (currently linux-only)
526 - para_client is integrated in para_audiod
527 - random/playlist selector: improved info strings
528 - new audiod commands: tasks, kill
529 - update to libortp-0.10.1
530 - para_fade: wake time defaults to 8 hours from now
531 - update to autoconf-2.60
533 ------------------------------------------
534 0.2.12 (2006-05-12) "oriented abstraction"
535 ------------------------------------------
537 Many user-visible changes in this release and lots of new
541 - the new optional dccp sender/receiver. It uses the datagram
542 congestion control protocol. You'll need a fairly new kernel
544 - paraslash works on Mac OS X (thanks to Gerd Becker)
545 - para_play renamed to para_write
546 - modular output plugin design (writers) for para_write
547 - new file_writer output plugin for para_write
548 - compress filter speed improvements
549 - update to libortp-0.9.1
550 - update to gengetopt-2.17rc
551 - para_client no longer depends on libreadline (as the
552 code for the interactive mode was removed).
553 - gcc-2-95 is no longer a supported compiler. It may still
554 work, but it gets no more testing.
555 - the tarball no longer contains the screenshot images which
556 reduces its size quite a bit.
557 - configure: new command line options: --enable-mysql-headers
558 and --enable-mysql-libs
560 ------------------------------------
561 0.2.11 (2006-03-11) "atomic duality"
562 ------------------------------------
564 Here it is, the first paraslash release developed with git. There
565 are fairly many user-visible changes in this release. As two out of
566 the three "database tools" of paraslash don't use a database at all,
567 they are now called "audio file selectors" instead.
570 - the cdt command (change database tool) becomes chs (change
572 - no more colon separators: The syntax of some options of
573 para_audiod and para_filter have changed. Use --help for
574 more info (and some examples).
575 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
576 - switch from cvs to git (should've done that earlier)
577 - the new ipc subsystem
578 - new audio file selector: playlist
579 - para_server: the dopey selector is now called "random",
580 and is the default selector. Use the --selector option to
581 choose another selector at startup, or the chs command to
582 change the selector at runtime.
583 - X86_64 fixes (thanks to Steffen Klassert)
586 --------------------------------------
587 0.2.10 (2006-02-17) "cyclic attractor"
588 --------------------------------------
590 Huge documentation update, a scrollable window for para_gui, ortp
591 improvements, and of course many small fixes not mentioned here.
592 The diffstat below is rather misleading as most insertions are due
593 to the new source documentation.
596 - para_server also uses the new error subsystem
597 - lots of new documentation (UTSL)
599 - keysyms for cursor keys and for next/previous page keys
600 - scrollable output window
601 - new internal commands: scroll up/down, page up/down
602 - fix color of command output.
603 - ortp: the --chunk_time and --header flags are no longer needed
604 for para_recv/para_audiod as this information is now encoded in
605 each rtp packet sent by para_server.
607 -------------------------------------------
608 0.2.9 (2006-01-24) "progressive turbulence"
609 -------------------------------------------
611 Internal audiod receivers/filters, the new error subsystem and
612 a lot of small improvements.
614 - para_recv and para_filter are integrated into the para_audiod
615 binary, i.e. audiod no longer spawns a new process for
616 each receiver/filter. As para_recv and para_filter might be
617 useful as standalone programs, they still get built (linked
618 against the same object files that are also used for audiod).
619 - further ortp timing improvements should reduce the CPU usage
620 of the ortp receiver.
621 - improved audio grabbing. The 'grab' command of para_audiod
622 has its own set of command line options. Read the output of
623 "para_audioc help grab" for more info.
624 - oggdec: configurable input prebuffer size.
625 - the new error subsystem gives better error diagnostics
626 and reduces code size.
628 -----------------------------------------
629 0.2.8 (2006-01-02) "dynamic accumulation"
630 -----------------------------------------
632 The new modular filter design and the para_play-hangs bugfix.
634 - new executable: para_filter. It combines para_mp3dec,
635 para_oggdec and para_compress. It also adds a further filter
636 type, wav, that just inserts a wave header at the desired point
637 of the filter chain. All 'piping' is done in-memory (i.e. no
638 read/write operations are used).
639 - para_play: fix a stupid bug that caused it to hang under
640 certain circumstances.
642 -------------------------------------------
643 0.2.7 (2006-12-27) "transparent invariance"
644 -------------------------------------------
646 Not many user-visible changes but a fair amount of internal improvements.
649 - The http sender buffers data if it can not be sent
650 out immediately (because the socket is not writable). This
651 should prevent para_server from shutting down the connection
652 too early on a loaded network.
653 - para_play also prebuffers data if it is told to start at a
654 future time by the --start_time option.
655 - The return of para_recv: It combines para_ortp_recv and
656 para_http_recv. Use the --receiver option to switch between
657 the two. para_recv builds without libortp, but contains
658 only the http receiver in this case.
659 - update to ortp 0.8.1. As this ortp release contains incompatible
660 changes, para_recv-0.2.7 won't link against older ortp libs.
661 - improved ortp timings.
662 - use of gcc-extensions that #define away for non-gcc and
665 -------------------------------------------
666 0.2.6 (2005-10-29) "recursive compensation"
667 -------------------------------------------
669 Transparent session encryption (uses openssl's Alleged RC4 cipher),
670 the internal find command and several other improvements and cleanups.
672 - Encrypt the session if encryption is requested by the client
673 (default for para_client 0.2.6). This is backwards
674 compatible, so older clients can still connect to para_server
675 0.2.6. Use the new client option --plain to request an
676 uncrypted session (off by default, must be set to on in
677 order to connect to para_server 0.2.x with 0 <= x <= 5).
678 - para_server uses an internal function to locate audio files
679 rather than calling find(1). The server option
680 --mysql_audio_file_dir replaces --mysql_find_cmd.
681 - documentation update
683 - header file cleanup
684 - para_client code cleanup
685 - para_gui: faster display of output of display commands
687 ------------------------------------------
688 0.2.5 (2005-10-13) "aggressive resolution"
689 ------------------------------------------
691 This release adds internal senders, i.e. no more external programs are
692 spawned for sending out the audio data. There are two different senders
693 available: The http sender and the ortp sender (former para_send which
694 is no longer needed).
696 The new sender code has a plugin-like design so it can be easily
697 extended should there be be any future need for supporting another
698 network streaming protocol. All senders are completely independent of
699 each other. In particular, the http and the ortp sender can operate
702 - new server command: sender to control senders at runtime.
703 Read the output of "para_server -h" and "para_client help
704 sender" for more information.
705 - para_recv renamed to para_ortp_recv
706 - new executable: para_http_recv, a simple command line
708 - major afs/mp3/ogg code simplifications due to internal
710 - ogg timing improvements
711 - fix several minor memory leaks (found by valgrind)
712 - empty stream definitions work again
713 - com_ne(): ignore errors on remove
714 - audiod: fix segfault on server restart
716 ---------------------------------------
717 0.2.4 (2005-09-21) "toxic anticipation"
718 ---------------------------------------
720 Several small improvements, fixes and the new grab command.
723 - new command: "grab" to grab the output of the stream reader
724 or any filters. Read the output of "para_audioc help grab"
725 for more information.
728 - audioc: new command line option: --bufsize to specify a
729 buffer size different from the default size 8192.
730 - improved error diagnostics for para_play.
731 - new configure option: --enable-ssldir so search for openssl in
733 - sdl_gui: Make it look nice again for 1024x768
734 - server: report total size of memory allocated with sbrk by malloc,
735 new command line option: --announce_time
737 -----------------------------------------
738 0.2.3 (2005-09-01) "hydrophilic movement"
739 -----------------------------------------
741 Two new executables and major feature enhancements.
743 - audiod filters: It is now possible to specify arbitrary many
744 (including none) filters for each supported audio
745 format. This can be used e.g. for normalizing volume,
746 transforming or grabbing the audio stream, or for using
747 visualizers. Read the output of "para_audiod -h" for the
748 syntax of the new --filter_cmd option.
749 - new executable: para_play, a tiny alsa player. It
750 can play wave files or raw pcm (16 bit little endian)
752 - new executable: para_compress, a dynamic range compressor
753 intended to keep audio output at a consistent volume. Derived
754 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
755 - audiod: New option: --stream_delay. This can be used in
756 a local network to syncronize the audio output of all
757 clients that play the same stream.
759 ------------------------------------------
760 0.2.2 (2005-08-19) "tangential excitation"
761 ------------------------------------------
763 Mostly internal changes in this release, but also some new commands
764 for the mysql database tool.
766 - cleanup exec.c, fix para_exec bug
767 - compile time loglevel (log messages below the given level
768 won't be compiled in, which reduces the size of the
770 - new log macros that shorten the size of the source code.
771 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
772 to send only zeros. With this workaround, para_audioc works
774 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
775 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
776 (new entry), "snp" (set numplayed). Read the manual for more
779 ---------------------------------------
780 0.2.1 (2005-08-15) "surreal experience"
781 ---------------------------------------
783 Here comes paraslash-0.2.1. It contains a couple of new features and,
784 surprise, only minor bug fixes.
786 - kill noisy mp3 debug message
787 - cleanup of the build system
788 - para_server and para_client directly use the crypto routines
789 of the openssl library rather than invoking the openssl command
791 - server/audiod: new option --user to switch to the given user
792 when invoked as root. Read the output of "para_server -h" for
794 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
795 status. Default: "para_audioc stat"
796 - sdl_gui: new option --pic_cmd to be used to download the picture.
797 Default: "para_client pic"
798 - audiod: 5 slots ought to be enough for everybody
799 - audiod: new status item: Uptime, kill hup command
801 ------------------------------------------
802 0.2.0 (2005-08-06) "distributed diffusion"
803 ------------------------------------------
805 After several month of increased development activity, paraslash-0.2.0
806 has arrived. It contains many new features and is much more
807 self-contained than the old 0.1.x series. Enjoy!
810 - para_server: fix hang on song change and crash on sighup.
811 Speed up mysql queries. The DIR_LIKE macro is gone.
812 - new executables: para_audiod, the local audio daemon that
813 starts playback (uses SCM_CREDENTIALS socket magic) and
814 para_audioc, the corresponding client.
815 - new executables: para_mp3dec/para_oggdec, two really teensy
816 decoders. para_mp3dec is based on libmad, para_oggdec requires
818 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
819 they are now called para_send and para_recv respectively.
820 - documentation updates
821 - para_gui is themable. For now there is the default theme that
822 looks as before and the simple theme: blue and easy.
823 - gui: audio streaming is now handled by audiod. Time display shows
824 playback time rather than streaming time
825 - slider: update to libzmw-0.2.0
826 - para_krell: fix crash on server shutdown
827 - switch from gzip to bzip2
829 ----------------------------------------
830 0.1.7 (2005-04-18) "melting penetration"
831 ----------------------------------------
833 The main change in this release is clearly the oggvorbis rewrite,
834 but there are also lots of smaller changes. If you intend to use both
835 the mp3 and the ogg plugin, it is recommended to use software mixing,
836 e.g. the dmix plugin which is provided by ALSA.
838 - new executables: para_ovsend and para_ovrecv for sending/receiving
839 oggvorbis files via rtp. Requires the open rtp library. Get it at
840 http://www.linphone.org/ortp/
841 - rewrite of the ogg_vorbis core code
842 - configure detects libzmw and, if detected, includes
843 para_slider to the list of binaries to be built by make
844 - server stream writers read from their associated fifo rather
846 - slider: two new sliders, lastplayed and numplayed
847 - fix nasty double free bug which caused random segfaults in case of
848 mp3 files with invalid header information
849 - gui: new command line option: --stream_timeout=seconds to
850 deactivate a slot if it is idle for that many seconds (default=`5')
853 ---------------------------------------
854 0.1.6 (2005-03-05) "asymptotic balance"
855 ---------------------------------------
857 Only little user-visible changes in this release. Mainly bugfixes and
858 core code cleanup. This is probably the most stable version ever if you
861 - fix several memory leaks
862 - rename default name of mysql database from "music" to "paraslash".
863 Use para_server's --mysql_database option if you do not want to
864 rename your old database.
865 - rework ogg vorbis code
866 - make update command work on mysql servers with LOCAL_INFILE
868 - gui: improved stream I/O (slots)
869 - simplified audio format API
870 - para_pob_ogg is gone
872 ------------------------------------
873 0.1.5 (2004-12-31) "opaque eternity"
874 ------------------------------------
876 Let's slide gently into the new year.
878 - new: para_slider (not built automatically, type "make
879 para_slider" to build). A toy for those who always felt that
880 creating stream definitions is difficult. See screenshots,
881 README and FEATURES for more info.
882 - improved signal handling. Fixes server segfault on SIGHUP
883 for linux kernels newer than Aug 24 2004 and makes para_gui
885 - reload database tool on SIGHUP
886 - improved help message for sl
887 - do not log "broken pipe" messages as errors. They are
889 - fix wrong error message on permission errors
891 -----------------------------------------
892 0.1.4 (2004-12-19) "tunneling transition"
893 -----------------------------------------
895 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
896 Hopefully, most of them got wiped out with this release. Some
897 enhancements went also in.
899 - improved error diagnostics for all commands
900 - stradd/picadd: overwrite previous contents if entry already
901 exists, rather than returning errors
902 - stradd: use current stream if invoked without args
903 - faster (and hopefully more stable) ogg-vorbis handling
904 - para_krell: reap children to avoid zombie-flooding in case
906 - si: report also server pid
907 - server: don't busy-loop if dbtool reports only invalid files.
908 - gui: CTRL+C works again, fix stream_read command line option
910 - fix mysql dbtool startup in case no database exists
911 - many small fixes and cleanups
913 ---------------------------------------
914 0.1.3: (2004-12-10) "vanishing inertia"
915 ---------------------------------------
917 Starting from this release, the database tools are integrated in the
918 server binary. This decreases server startup time, reduces code size
919 and speeds up database commands. However, the layout of the underlying
920 mysql database changed only slightly and 0.1.3 should be backwards
921 compatible in that respect.
925 - If mysql is not detected at compile time, or fails to init
926 at runtime, fall back to the dopey database tool which should
928 - para_dbtool and dbtool.conf are gone. All mysql specific
929 options are read from server.conf and are prefixed by 'mysql_'.
930 - new command: cdt (change database tool)
931 - new command line option: dbtool (choose startup database tool)
932 - The name of current stream is now stored in the database,
933 so paraslash remembers its current stream when restarted.
934 - new command: csp (change stream and play)
935 - para_gui also reports current database tool and server uptime
937 -------------------------------------------
938 0.1.2: (2004-11-28) "spherical fluctuation"
939 -------------------------------------------
941 Point release before the big dbtool changes go in.
943 - dbtool: rename ca to cam (copy all meta data). It now also
944 copies numplayed and lastplayed time as well as the picture
946 - fix endless-loop-bug caused by mp3 files with invalid header
948 -----------------------------------------
949 0.1.1: (2004-11-05) "floating atmosphere"
950 -----------------------------------------
953 - new dbtool command: mbox. Browse your sound-file collection
954 with your favorite mail reader.
955 - several small fixes
957 -------------------------------------
958 0.1.0: (2004-10-22) "rotating cortex"
959 -------------------------------------
961 - fix logging bug for loglevel > VERBOSE
963 - correct timings for vbr mp3s
964 - modular audio format support
965 - ogg-vorbis support (experimental)
966 - new server option: autoplay
968 -----------------------------------------
969 0.0.99: (2004-07-25) "harmonic deviation"
970 -----------------------------------------
972 - rename projectname from icc to paraslash (play, archive, rate
973 and stream large audio sets happily)
974 - paraslash is no longer restricted to one particular audio
976 - new dbtool commands (stradd, strq, strdel) for easy stream
977 managment w/o configuration file. That obsoletes stream_defs
978 file/config option for dbtool.
979 - picadd accepts jpeg data from stdin
980 - new server commands: ps (select previous stream), sc (song change)
981 - new default pictures for sdl_gui
982 - gui: new key_map option for binding commands and internal
983 functions to arbitrary keys, nice help screen, rip out
984 soundcard/linux specific stuff, avoid noise artefacts while jumping,
985 show silly logo on startup
986 - new executables: para_fade for fading volume, para_dbadm for
987 manipulating attributes
988 - cdb adds _all_ tables to mysql database
989 - revised and beautified documentation
990 - sample dbtool rewritten in C
993 ---------------------------------------------
994 0.0.98: (2003-12-26) "incremental smoothness"
995 ---------------------------------------------
997 - kick icecast in favour of poc. That removes some races and reduces
998 core code considerably.
999 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1000 give finer info on afs' status.
1001 - gui can start decoder (see config options). Further new gui
1002 commands: refresh (^L), jmp (F1-F10)
1003 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1004 terminates gui. This fixes dead instances consuming memory
1006 - new dbtool command: verb for sending verbatim sql queries.
1007 - fix pid_list races (by removing pid_list)
1010 --------------------
1011 0.0.97: (2003-10-26)
1012 --------------------
1014 - installation prefix now defaults to /usr/local
1015 - new commands for gui: snozze, sleep and reread config
1016 - config file for gui and sdl_gui
1017 - fix problems with filenames containing funny characters
1018 (reported by Thomas Forell)
1019 - improved signal handling for gui, now it rereads conf on SIGHUP
1020 - new dbtool command: cdb (create database)
1021 - switch from argtable to gengetopt
1022 - major code cleanup and speed improvements
1023 - fix several potential buffer overflows
1024 - many small fixes and cleanups
1030 - easy stream_defs syntax
1031 - sdl_gui can display images associated to the file being played
1032 - Major feature enhancements for icc_gui including dynamic text
1033 placement and the top/bottom window design
1034 - vrfy/clean now also checks for NULL values in attributes as
1035 well as for invalid picture pointers
1036 - fix long outstanding case sensitivity bug
1037 - many small fixes and cleanups
1043 - sdl gui runs much faster
1044 - new dbtool command: ca (copy attributes)
1045 - count and display number of times the song has been played
1046 - new feature: scoring
1047 - command line options for sdl_gui
1048 - simpler syntax of streams file
1049 - decrease network traffic of stat
1051 - many small fixes and cleanups
1057 - new server command: ns (next stream)
1058 - new icc_gui command: c (change stream)
1060 - stat shows also id3 tag info
1062 - log flodding bug fixed
1063 - many small fixes and cleanups
1069 - colors for icc_gui
1070 - icc_gui sets volume directly (linux only)
1071 - proper locking that fixes some races
1072 - fix security bug that caused commands to be executed even
1073 with unsufficient permissions
1074 - new command: hup to make all servers reread their configuration file
1075 - icecast meta data streaming
1076 - many small fixes and cleanups
