1 ---------------------------------------------
2 0.?.? (to be announced) "volatile relativity"
3 ---------------------------------------------
5 --------------------------------------
6 0.4.11 (2012-07-20) "mutual diversity"
7 --------------------------------------
9 The major feature in this release is the new sideband API for
10 client-server communication. This API will be used exclusively starting
11 with 0.5.0, which breaks backward compatibility but allows to get rid
12 of quite some compatibility code. Other noteworthy changes include
13 decoder latency improvements and a long-standing bug fix for the
16 - Sideband connections: If both para_server and para_client
17 support this feature, data is sent as a multiplexed stream.
18 - The --no_default_filters option of para_filter has been
20 - Several fixes and latency improvements to various decoders.
21 - The ALSA writer now limits the prebuffer time to 500ms.
22 - Documentation improvements.
23 - Overhaul of the command_util.sh script.
24 - Fixes for some minor problems found by the clang analyzer.
25 - Compiles (almost) without warnings on gcc-3.
26 - Robustness improvements of the buffer tree code.
28 ------------------------------------------
29 0.4.10 (2012-03-30) "heterogeneous vacuum"
30 ------------------------------------------
32 Nothing earth-shaking in this release, but quite a few usability
33 improvements and the usual mix of cleanups and fixes.
35 - The --no_default_filters option of para_filter has been
36 deprecated. It still works but has no effect and will be
37 removed in the next version.
38 - para_gui now prints also the stderr output of the executing
39 command in the bottom window.
40 - Cleanup and consolidation of the various wrappers for
41 write(), writev(), send() and friends.
42 - The obscure error messages on mmap() failures have been
43 replaced by meaningful messages. This affects mainly
45 - para_audioc: Cleanups and memory leak fixes.
46 - Test 0004-server no longer fails if para_server is not
48 - New configure options: --with-id3tag-{headers,libs}.
50 -------------------------------------
51 0.4.9 (2011-12-06) "hybrid causality"
52 -------------------------------------
54 Support for another audio format, interactive mode for para_client
55 and para_audiod and many small improvements/fixes all over the place.
57 - Support for flac, the free lossless audio codec.
58 - Fix for an endless loop in the mp3 decoder for certain
60 - When executed without specifying a command, para_client
61 and para_audioc start an interactive shell (requires
62 libreadline being installed). The interactive mode offers
63 full tab completion and command line history.
64 - autogen.sh now detects a distcc setup and adjusts the
65 parameter for the -j option of make accordingly.
66 - Shared memory areas are no longer restricted to 64K. We now
67 detect the maximal size of a shared memory area at runtime.
68 - cleanup of the internal uptime API.
69 - para_server prefaults the mmapped audio file to avoid
71 - A new test for the test-suite that exercises the
72 communication between para_server and para_audiod.
73 - The alsa writer eats up less CPU cycles when configured to
75 - Simplified and unified receiver code.
77 - Commands which print a list of matching audio files now
78 emit a meaningful error message if no audio file matched the
81 --------------------------------------
82 0.4.8 (2011-08-19) "nested assignment"
83 --------------------------------------
85 Gcrypt support, the overhauled osx writer and regex format specifiers
86 are the highlights of this release.
88 - support for libgcrypt as a drop-in replacement for openssl.
89 Run configure --enable-cryptolib=gcrypt to link against
90 libgcrypt. The two crypto implementations are compatible to
91 each other, i.e. a para_client executable linked against
92 gcrypt can connect to para_server linked against libssl
94 - Rewrite of the osx writer (output plugin for Mac OS).
95 - audiod: The format specifier for receivers, filters and
96 writers is now treated as a regular expression. This allows
97 to replace 5 lines in the config file (one for each audio
98 format) by one single line. See the manual for details.
99 - The *.cmdline.[ch] files are no longer contained in the released
100 tarballs. This reduces the size of the tarballs but requires
101 gengetopt to build the tarball.
102 - Compiles cleanly also with llvm/clang.
103 - Corrupt mp3 files are handled more gracefully.
104 - The alsa writer uses poll fds instead of computing timeouts.
105 - Cleanup of the generic writer API.
106 - sched: Optimized zero timeouts.
107 - vss timeout cleanups.
108 - oggdec fixes and improvements.
110 --------------------------------------
111 0.4.7 (2011-06-01) "infinite rollback"
112 --------------------------------------
114 The new ao writer, support for ssh RSA keys and a couple of other
117 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
118 platforms through the libao audio library.
119 - Support for RSA keys generated with ssh-keygen.
120 - configure: improved options for ogg/vorbis/speex.
121 - The git version reported by --version always matches HEAD.
122 - The autogen script detects the number of processors and
123 runs a parallel make if possible.
124 - Major cleanup of the crypto API.
125 - Documentation updates.
127 ------------------------------------------
128 0.4.6 (2011-03-31) "deterministic entropy"
129 ------------------------------------------
131 Lots of ogg/vorbis improvements, the new test suite, enhancements
132 for para_gui and a fair amount of other bug fixes.
134 - For DCCP/OGG streams the audio file header is only sent once
135 at the beginning of the stream rather than periodically
136 every five seconds. This reduces network traffic and the
138 - The vorbis comment header is replaced by an empty dummy header
139 before the header is sent over the network. This also results in
140 less network traffic and smaller FEC groups.
141 - The new "test" make target allows to perform some sanity checks prior
142 to installing the package.
143 - ogg timing fixes and performance improvements
144 - Scheduler improvements
145 - Proper exit codes for para_write
146 - para_gui: New option --theme to select a startup theme. Several
147 other improvements and fixes.
148 - aacdec error message cleanups
149 - simplified color error handling
151 --------------------------------------------
152 0.4.5 (2010-12-17) "symmetric randomization"
153 --------------------------------------------
155 Bug fixes, internal cleanups and variable-sized FEC slices.
157 - Contains a fix for an invalid-free-bug in the ogg audio format
159 - Switching off the DCCP sender works again.
160 - para_audiod handles crashes of para_server more robustly.
161 - Internal scheduler and writer cleanups.
162 - Reduced latency due to variable-sized FEC slices.
163 - Improved documentation and error diagnostics.
164 - The build of para_server is now optional, allowing the build
165 to succeed in case libosl is not installed.
167 ------------------------------------------
168 0.4.4 (2010-08-06) "persistent regularity"
169 ------------------------------------------
171 Support for yet another audio format, para_write improvements and
174 - Support for the speex codec.
175 - Support for sample formats other than 16 bit little endian.
176 - error2.h is now created by a perl script which speeds up configure
178 - Fix a bug in the aac decoder which could lead to segfaults in
179 para_filter/para_audiod.
180 - Fixes for autoconf-2.66.
182 ----------------------------------------
183 0.4.3 (2010-07-05) "imaginary radiation"
184 ----------------------------------------
186 Many improvements for the DCCP and the UDP transport, the new user
187 manual and the usual mix of bug fixes and internal improvements.
189 - FEC support for the DCCP sender (Gerrit Renker). The new
190 --dccp_max_slice_size, --dccp_data_slices_per_group and
191 --dccp_slices_per_group options can be used to set the FEC
192 parameters for the DCCP transport.
193 - DNS lookups for UDP targets (Gerrit Renker).
194 - The new user manual replaces the README, README.afs, REQUIREMENTS
195 and INSTALL documents.
196 - Fix an end-of-file detection bug in the oggdec filter.
197 - The new nonblock API.
198 - Both options of the oggdec filter have been removed.
199 - New debug mode for the internal scheduler.
201 ------------------------------------------
202 0.4.2 (2010-04-23) "associative expansion"
203 ------------------------------------------
205 It's been some time since the last release, but finally here is
206 paraslash-0.4.2. The bulk of the changes comes from the new buffer
207 tree API, but there are changes all over the tree. Mainly performance
208 and usability improvements, but also quite some bug fixes.
210 - The new buffer tree API.
211 - DCCP: Support for CCID negotiation (Gerrit Renker).
212 - UDP robustness fixes.
213 - The --bufsize option for mp3dec is gone as it no longer makes sense
214 for the new buffer tree API.
215 - Fix audible buffer underruns for wma streams.
216 - The alsa writer no longer prints meaningless underrun durations.
217 - audiod: Defaults work also for udp streams. If no filter is
218 given for an audio format that is received via upd, fecdec is
219 automatically added as the first filter (along with the decoder).
221 ---------------------------------------
222 0.4.1 (2009-12-22) "concurrent horizon"
223 ---------------------------------------
225 Support for another audio format, minor feature enhancements and lots of bug
226 fixes. All fixes that have been accumulated in the maint branch (in particular
227 those mentionened in the 0.3.6 release notes) appear in this release as well.
230 - new afh option: --human to activate human-readable output.
231 - new server/audiod option: --log-timing to print timing information.
232 - build system improvements.
233 - source code documentation updates.
235 -------------------------------------
236 0.3.6 (2009-12-07) "cubic continuity"
237 -------------------------------------
239 Quite a few bugs have been found and fixed since 0.3.5, so here's
240 another 0.3.x release. No new features.
242 - Always check return value of malloc().
243 - ogg vorbis/FEC: Do not write garbage after the audio file header.
244 - exit if root privileges could not be dropped.
245 - FEC: Fix computation of extra slices.
246 - oss: Fix check for empty input buffer.
247 - Avoid buffer underruns due to filter chain output buffer constraints.
248 - server: Fix assignment of afs_pid.
249 - Don't panic if the afs database contains unknown audio formats.
250 - http/dccp: Do not send the audio file header twice.
251 - FEC: Timing improvements.
253 ----------------------------------------------
254 0.4.0 (2009-11-10) "simultaneous independence"
255 ----------------------------------------------
257 Two significant changes which require the new version number: The
258 improved authentication dialog and the fact that the database code
259 has been moved to a library, libosl. To use the new version, you have
260 to generate new RSA keys, see INSTALL for details. A shell script is
261 provided for conversion of the 0.3 database to the new 0.4 format.
263 - stronger crypto for client authentication
264 - the database code has been moved to a library
265 - improved status item handling
266 - cleanup of the build system
267 - The "-V" option now also prints the git version
268 - the new parser-friendly listing mode for the ls and stat commands
269 - mandatory rc4 encryption
270 - major audio format handler cleanups
271 - (id3,...) tags are no longer stored as a combined string in the database
272 - new mood methods: artist_matches, title_matches, comment_matches,
273 album_matches, year_maches, year.
275 --------------------------------------------
276 0.3.5 (2009-09-21) "symplectic separability"
277 --------------------------------------------
279 Full client support for *BSD Unixes, complete re-write of the ogg
280 vorbis audio format handler, various improvements all over the place
281 and the usual mix of bugfixes. This release marks the end of the 0.3
282 series if no serious problems show up.
284 - the new oss writer (supported on *BSD and Linux)
285 - rewrite of the ogg vorbis audio format handler. It's
286 recommended to replace the chunk tables of existing ogg
287 vorbis files in the afs database by re-adding these files
289 - support for netmask subsets (Gerrit Renker)
290 - the new prebuffer filter
291 - improved signal handling
292 - variable fec output buffer size
293 - improved FEC timing fixes audible buffer underruns in UDP mode
294 - --log_color actually works
295 - new ls option: -d (print dates as seconds after the epoch)
296 - update to gengetopt 2.22.2
297 - support for RSA keys of size > 512 bits
298 - new option "mixer_channel" for para_fade
300 -----------------------------------------
301 0.3.4 (2009-05-07) "elliptic inheritance"
302 -----------------------------------------
304 The new udp sender, forward error correction, colored logs and various
305 other improvements. As the udp sender does not depend on any special
306 libraries, it is built unconditionally.
308 - The udp sender replaces the ortp sender. The new code uses forward
309 error correction to protect against packet losses. Many thanks to
310 Gerrit Renker for providing ipv6 support.
311 - The default port for udp streaming now defaults to 8000, like
312 for the http and the dccp senders/receivers.
313 - Loglevels are now specified as symbolic names, e.g.
315 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
316 - para_server/para_audiod: Color support for log messages.
317 - new options for mp3dec: --ignore-crc, --bufsize
318 - new audiod option: --config-file.
319 - gengetopt cleanups.
320 - Improved help/man pages: The documentation of para_audiod,
321 para_recv, para_filter and para_write now also contains
322 all options of the available receivers/filters/writers. The
323 man page of para_fade contains a description of the different
325 - More source code documentation.
328 --------------------------------------------
329 0.3.3 (2008-12-01) "axiomatic perspectivity"
330 --------------------------------------------
332 Internal code cleanups, bug fixes, improved tag handling and the new
333 amplification filter.
335 - para_server uses the generic scheduling code.
336 - overhaul of the virtual streaming system.
337 - mp3: id3 version 2 support via libid3tag (optional)
338 - ogg: vorbis comment support.
339 - aac meta info support.
340 - mp3 audio format handler cleanups.
341 - new filter: "amp" to amplify the amplitude of the audio stream
342 - new status item/database entry: amplification. It is
343 used by the amp filter to pre-amplify the audio stream.
344 - fix a close-without-open bug in para_write.
345 - fix a bug in com_init() which was introduced in 0.3.2.
346 - better error diagnostics for para_client.
348 -----------------------------------------
349 0.3.2 (2008-04-11) "probabilistic parity"
350 -----------------------------------------
352 The new para_afh executable, scheduling and documentation improvements.
354 - new ls option: -lc (list chunk table)
355 - new executable: para_afh, the stand-alone audio file handler tool
356 - afs commands can send output more than SHMMAX (32MB on Linux). This
357 also reduces the memory usage of commands that produce large amounts
359 - major scheduler and audiod cleanups.
360 - more detailed and much nicer man pages.
362 ---------------------------------------
363 0.3.1 (2008-02-23) "liquid interaction"
364 ---------------------------------------
366 A mix of cleanups, bug fixes, improvements, and some new features. No
367 significant changes to the new database (osl) code, which is generally
370 - Share some similar/duplicate code between the http and the
372 - Generic access control lists for paraslash senders.
373 - dccp sender: Access control lists, connection limiting and support
374 for the allow,deny,on,off,help sender commands.
375 - The default dccp port changed from 5001 to 8000 (suggested by
377 - para_server starts even if not all public keys could be loaded.
378 - Audiod performance improvements.
379 - fix a bug in the "off" command of the http sender.
380 - fix some fd and memory leaks.
381 - Update to gengetopt-2.22.
383 -------------------------------------
384 0.3.0 (2008-01-12) "solar saturation"
385 -------------------------------------
387 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
390 Usually one might expect lots of new features AND a big increase in size
391 for a major release like this.
393 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
394 ever. The decrease in size is mostly due to the removal of some
395 graphical tools (which were only quick hacks anyway). But also the
396 fact that the mysql code is gone cuts down the size a bit.
398 Being independent of mysql comes at a cost: The fact that paraslash
399 now contains its own database (the object storage layer, osl) increases
400 the (stripped) binary size of para_server by ~50K on i386.
402 - no more restrictions on unique basenames.
403 - independent of mysql: The new self-contained object
404 storage layer (osl) replaces the mysql database.
405 - New executable para_fsck: Check integrity of osl tables.
407 - Reliable audio file move/rename detection.
408 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
409 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
411 - the new osl-based audio file selector (afs) replaces the random,
412 the playlist and the mysql selector of paraslash-0.2.x.
413 - IPv6 support (thanks to Gerrit Renker).
414 - paraslash-0.2.x streams are now called "moods". Writing
415 0.3.x-mood definitions should be both easier and more
416 powerful than writing 0.2.x-stream definitions.
417 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
418 been removed. The world is a better place without them. However,
419 para_gui is still there.
420 - afs tracks audio file selection also in playlist mode.
421 - few easy-to-use afs commands replace the many not-so-easy-to-use
422 mysql commands (and are available also in playlist mode).
423 - Improved error subsystem.
424 - The earth-shaking new logo.
426 -----------------------------------------
427 0.2.17 (2007-11-20) "isotropic threshold"
428 -----------------------------------------
430 Mainly bugfixes and cleanups in this version which marks the end of
431 the 0.2.x series if no serious bugs show up after the release.
433 - mysql_selector: fix a locking bug.
434 - universal chunk queueing.
435 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
437 - be more carful wrt. signed vs. unsigned argument passing.
438 - cleanup error.h and fix some references to invalid error
440 - update to gengetopt-2.21.
441 - update to ortp-0.13.1.
442 - autoconf: extend checks for headers, library functions and
443 compiler characteristics.
444 - Fix streaming of large mp3 files.
445 - Fix an off-by-one bug in playlist handling.
447 --------------------------------------
448 0.2.16 (2007-04-05) "neural discharge"
449 --------------------------------------
451 The main change in this release is the major audio format handler
452 cleanup which removes some similar/duplicate code and makes it easier
453 to implement plugins for other audio formats. Of course, the usual mix
454 of other improvements/changes/bugfixes also made it into the release.
456 - simplified audio format handlers (most of the handling functions
457 were moved one layer up to the virtual streaming system).
458 - para_server uses mmap to read audio files
459 - repositioning of mp3 streams is much faster, in particular for
460 jumping near the end of large mp3 files.
461 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
463 - fix a bug in para_filter that caused decoding of aac files
464 to start only after a few seconds.
465 - fix osx_writer hangs
466 - simplified dccp code (thanks to Gerrit Renker)
467 - the compress filter works also on big endian systems (ppc)
469 -----------------------------------------
470 0.2.15 (2007-02-16) "inductive resonance"
471 -----------------------------------------
473 Minor improvements, more documentation and a bunch of bug fixes.
475 - para_server: The server.users file is only read once on server
476 startup rather than for each connection
477 - mp3dec: Fix decoding of corrupt mp3 files
478 - afs (audio file sender) is now called vss (virtual streaming
479 system). Consequently, the permission flags specified in
480 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
481 become VSS_READ and VSS_WRITE respectively.
482 - para_audiod/para_filter: Fix a bug that caused the last chunk
483 of audio data not being written under certain circumstances
484 - audiod: compute the difference of server time and local time
486 - para_server/para_audiod: Fix some memory leaks
487 - documentation improvements
488 - configure.ac: fix checks for para_krell
491 -------------------------------------------
492 0.2.14 (2006-10-15) "transient singularity"
493 -------------------------------------------
495 The only major enhancement of this version is the osx writer which completes
496 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
497 until now for reasons beyond the scope of this changelog entry.
499 - new output plugin for Mac Os: the osx writer
500 - rename configure command line options from --enable-xxx-headers to
501 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
502 - configure: new command line options: --with-mad-headers,
503 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
504 - some robustness fixes
505 - dymamic audio format recognition for audiod
506 - para_server: new command line option: --autoplay_delay
507 - para_audiod: new command line option: --clock_diff_count
509 ---------------------------------------
510 0.2.13 (2006-07-14) "sonic convolution"
511 ---------------------------------------
513 A bunch of new features and core changes.
515 - the new paraslash scheduler, short and sweet.
516 - Support for m4a/mp4 files via the new aac audio format
517 handler/filter (requires libfaad).
518 - each writer has its own command line parser, just like
519 para_recv and para_filter.
520 - para_client and para_audioc use the error subsystem
521 - writers are integrated in para_audiod (currently linux-only)
522 - para_client is integrated in para_audiod
523 - random/playlist selector: improved info strings
524 - new audiod commands: tasks, kill
525 - update to libortp-0.10.1
526 - para_fade: wake time defaults to 8 hours from now
527 - update to autoconf-2.60
530 ------------------------------------------
531 0.2.12 (2006-05-12) "oriented abstraction"
532 ------------------------------------------
534 Many user-visible changes in this release and lots of new
538 - the new optional dccp sender/receiver. It uses the datagram
539 congestion control protocol. You'll need a fairly new kernel
541 - paraslash works on Mac OS X (thanks to Gerd Becker)
542 - para_play renamed to para_write
543 - modular output plugin design (writers) for para_write
544 - new file_writer output plugin for para_write
545 - compress filter speed improvements
546 - update to libortp-0.9.1
547 - update to gengetopt-2.17rc
548 - para_client no longer depends on libreadline (as the
549 code for the interactive mode was removed).
550 - gcc-2-95 is no longer a supported compiler. It may still
551 work, but it gets no more testing.
552 - the tarball no longer contains the screenshot images which
553 reduces its size quite a bit.
554 - configure: new command line options: --enable-mysql-headers
555 and --enable-mysql-libs
557 ------------------------------------
558 0.2.11 (2006-03-11) "atomic duality"
559 ------------------------------------
561 Here it is, the first paraslash release developed with git. There
562 are fairly many user-visible changes in this release. As two out of
563 the three "database tools" of paraslash don't use a database at all,
564 they are now called "audio file selectors" instead.
567 - the cdt command (change database tool) becomes chs (change
569 - no more colon separators: The syntax of some options of
570 para_audiod and para_filter have changed. Use --help for
571 more info (and some examples).
572 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
573 - switch from cvs to git (should've done that earlier)
574 - the new ipc subsystem
575 - new audio file selector: playlist
576 - para_server: the dopey selector is now called "random",
577 and is the default selector. Use the --selector option to
578 choose another selector at startup, or the chs command to
579 change the selector at runtime.
580 - X86_64 fixes (thanks to Steffen Klassert)
584 --------------------------------------
585 0.2.10 (2006-02-17) "cyclic attractor"
586 --------------------------------------
588 Huge documentation update, a scrollable window for para_gui, ortp
589 improvements, and of course many small fixes not mentioned here.
590 The diffstat below is rather misleading as most insertions are due
591 to the new source documentation.
594 - para_server also uses the new error subsystem
595 - lots of new documentation (UTSL)
597 - keysyms for cursor keys and for next/previous page keys
598 - scrollable output window
599 - new internal commands: scroll up/down, page up/down
600 - fix color of command output.
601 - ortp: the --chunk_time and --header flags are no longer needed
602 for para_recv/para_audiod as this information is now encoded in
603 each rtp packet sent by para_server.
606 -------------------------------------------
607 0.2.9 (2006-01-24) "progressive turbulence"
608 -------------------------------------------
610 Internal audiod receivers/filters, the new error subsystem and
611 a lot of small improvements.
613 - para_recv and para_filter are integrated into the para_audiod
614 binary, i.e. audiod no longer spawns a new process for
615 each receiver/filter. As para_recv and para_filter might be
616 useful as standalone programs, they still get built (linked
617 against the same object files that are also used for audiod).
618 - further ortp timing improvements should reduce the CPU usage
619 of the ortp receiver.
620 - improved audio grabbing. The 'grab' command of para_audiod
621 has its own set of command line options. Read the output of
622 "para_audioc help grab" for more info.
623 - oggdec: configurable input prebuffer size.
624 - the new error subsystem gives better error diagnostics
625 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.
643 -------------------------------------------
644 0.2.7 (2006-12-27) "transparent invariance"
645 -------------------------------------------
647 Not many user-visible changes but a fair amount of internal improvements.
650 - The http sender buffers data if it can not be sent
651 out immediately (because the socket is not writable). This
652 should prevent para_server from shutting down the connection
653 too early on a loaded network.
654 - para_play also prebuffers data if it is told to start at a
655 future time by the --start_time option.
656 - The return of para_recv: It combines para_ortp_recv and
657 para_http_recv. Use the --receiver option to switch between
658 the two. para_recv builds without libortp, but contains
659 only the http receiver in this case.
660 - update to ortp 0.8.1. As this ortp release contains incompatible
661 changes, para_recv-0.2.7 won't link against older ortp libs.
662 - improved ortp timings.
663 - use of gcc-extensions that #define away for non-gcc and
667 -------------------------------------------
668 0.2.6 (2005-10-29) "recursive compensation"
669 -------------------------------------------
671 Transparent session encryption (uses openssl's Alleged RC4 cipher),
672 the internal find command and several other improvements and cleanups.
674 - Encrypt the session if encryption is requested by the client
675 (default for para_client 0.2.6). This is backwards
676 compatible, so older clients can still connect to para_server
677 0.2.6. Use the new client option --plain to request an
678 uncrypted session (off by default, must be set to on in
679 order to connect to para_server 0.2.x with 0 <= x <= 5).
680 - para_server uses an internal function to locate audio files
681 rather than calling find(1). The server option
682 --mysql_audio_file_dir replaces --mysql_find_cmd.
683 - documentation update
685 - header file cleanup
686 - para_client code cleanup
687 - 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
720 ---------------------------------------
721 0.2.4 (2005-09-21) "toxic anticipation"
722 ---------------------------------------
724 Several small improvements, fixes and the new grab command.
727 - new command: "grab" to grab the output of the stream reader
728 or any filters. Read the output of "para_audioc help grab"
729 for more information.
732 - audioc: new command line option: --bufsize to specify a
733 buffer size different from the default size 8192.
734 - improved error diagnostics for para_play.
735 - new configure option: --enable-ssldir so search for openssl in
737 - sdl_gui: Make it look nice again for 1024x768
738 - server: report total size of memory allocated with sbrk by malloc,
739 new command line option: --announce_time
742 -----------------------------------------
743 0.2.3 (2005-09-01) "hydrophilic movement"
744 -----------------------------------------
746 Two new executables and major feature enhancements.
748 - audiod filters: It is now possible to specify arbitrary many
749 (including none) filters for each supported audio
750 format. This can be used e.g. for normalizing volume,
751 transforming or grabbing the audio stream, or for using
752 visualizers. Read the output of "para_audiod -h" for the
753 syntax of the new --filter_cmd option.
754 - new executable: para_play, a tiny alsa player. It
755 can play wave files or raw pcm (16 bit little endian)
757 - new executable: para_compress, a dynamic range compressor
758 intended to keep audio output at a consistent volume. Derived
759 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
760 - audiod: New option: --stream_delay. This can be used in
761 a local network to syncronize the audio output of all
762 clients that play the same stream.
765 ------------------------------------------
766 0.2.2 (2005-08-19) "tangential excitation"
767 ------------------------------------------
769 Mostly internal changes in this release, but also some new commands
770 for the mysql database tool.
772 - cleanup exec.c, fix para_exec bug
773 - compile time loglevel (log messages below the given level
774 won't be compiled in, which reduces the size of the
776 - new log macros that shorten the size of the source code.
777 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
778 to send only zeros. With this workaround, para_audioc works
780 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
781 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
782 (new entry), "snp" (set numplayed). Read the manual for more
786 ---------------------------------------
787 0.2.1 (2005-08-15) "surreal experience"
788 ---------------------------------------
790 Here comes paraslash-0.2.1. It contains a couple of new features and,
791 surprise, only minor bug fixes.
793 - kill noisy mp3 debug message
794 - cleanup of the build system
795 - para_server and para_client directly use the crypto routines
796 of the openssl library rather than invoking the openssl command
798 - server/audiod: new option --user to switch to the given user
799 when invoked as root. Read the output of "para_server -h" for
801 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
802 status. Default: "para_audioc stat"
803 - sdl_gui: new option --pic_cmd to be used to download the picture.
804 Default: "para_client pic"
805 - audiod: 5 slots ought to be enough for everybody
806 - audiod: new status item: Uptime, kill hup command
810 ------------------------------------------
811 0.2.0 (2005-08-06) "distributed diffusion"
812 ------------------------------------------
814 After several month of increased development activity, paraslash-0.2.0
815 has arrived. It contains many new features and is much more
816 self-contained than the old 0.1.x series. Enjoy!
819 - para_server: fix hang on song change and crash on sighup.
820 Speed up mysql queries. The DIR_LIKE macro is gone.
821 - new executables: para_audiod, the local audio daemon that
822 starts playback (uses SCM_CREDENTIALS socket magic) and
823 para_audioc, the corresponding client.
824 - new executables: para_mp3dec/para_oggdec, two really teensy
825 decoders. para_mp3dec is based on libmad, para_oggdec requires
827 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
828 they are now called para_send and para_recv respectively.
829 - documentation updates
830 - para_gui is themable. For now there is the default theme that
831 looks as before and the simple theme: blue and easy.
832 - gui: audio streaming is now handled by audiod. Time display shows
833 playback time rather than streaming time
834 - slider: update to libzmw-0.2.0
835 - para_krell: fix crash on server shutdown
836 - switch from gzip to bzip2
839 ----------------------------------------
840 0.1.7 (2005-04-18) "melting penetration"
841 ----------------------------------------
843 The main change in this release is clearly the oggvorbis rewrite,
844 but there are also lots of smaller changes. If you intend to use both
845 the mp3 and the ogg plugin, it is recommended to use software mixing,
846 e.g. the dmix plugin which is provided by ALSA.
848 - new executables: para_ovsend and para_ovrecv for sending/receiving
849 oggvorbis files via rtp. Requires the open rtp library. Get it at
850 http://www.linphone.org/ortp/
851 - rewrite of the ogg_vorbis core code
852 - configure detects libzmw and, if detected, includes
853 para_slider to the list of binaries to be built by make
854 - server stream writers read from their associated fifo rather
856 - slider: two new sliders, lastplayed and numplayed
857 - fix nasty double free bug which caused random segfaults in case of
858 mp3 files with invalid header information
859 - gui: new command line option: --stream_timeout=seconds to
860 deactivate a slot if it is idle for that many seconds (default=`5')
864 ---------------------------------------
865 0.1.6 (2005-03-05) "asymptotic balance"
866 ---------------------------------------
868 Only little user-visible changes in this release. Mainly bugfixes and
869 core code cleanup. This is probably the most stable version ever if you
872 - fix several memory leaks
873 - rename default name of mysql database from "music" to "paraslash".
874 Use para_server's --mysql_database option if you do not want to
875 rename your old database.
876 - rework ogg vorbis code
877 - make update command work on mysql servers with LOCAL_INFILE
879 - gui: improved stream I/O (slots)
880 - simplified audio format API
881 - para_pob_ogg is gone
883 ------------------------------------
884 0.1.5 (2004-12-31) "opaque eternity"
885 ------------------------------------
887 Let's slide gently into the new year.
889 - new: para_slider (not built automatically, type "make
890 para_slider" to build). A toy for those who always felt that
891 creating stream definitions is difficult. See screenshots,
892 README and FEATURES for more info.
893 - improved signal handling. Fixes server segfault on SIGHUP
894 for linux kernels newer than Aug 24 2004 and makes para_gui
896 - reload database tool on SIGHUP
897 - improved help message for sl
898 - do not log "broken pipe" messages as errors. They are
900 - fix wrong error message on permission errors
902 -----------------------------------------
903 0.1.4 (2004-12-19) "tunneling transition"
904 -----------------------------------------
906 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
907 Hopefully, most of them got wiped out with this release. Some
908 enhancements went also in.
910 - improved error diagnostics for all commands
911 - stradd/picadd: overwrite previous contents if entry already
912 exists, rather than returning errors
913 - stradd: use current stream if invoked without args
914 - faster (and hopefully more stable) ogg-vorbis handling
915 - para_krell: reap children to avoid zombie-flooding in case
917 - si: report also server pid
918 - server: don't busy-loop if dbtool reports only invalid files.
919 - gui: CTRL+C works again, fix stream_read command line option
921 - fix mysql dbtool startup in case no database exists
922 - many small fixes and cleanups
924 ---------------------------------------
925 0.1.3: (2004-12-10) "vanishing inertia"
926 ---------------------------------------
928 Starting from this release, the database tools are integrated in the
929 server binary. This decreases server startup time, reduces code size
930 and speeds up database commands. However, the layout of the underlying
931 mysql database changed only slightly and 0.1.3 should be backwards
932 compatible in that respect.
936 - If mysql is not detected at compile time, or fails to init
937 at runtime, fall back to the dopey database tool which should
939 - para_dbtool and dbtool.conf are gone. All mysql specific
940 options are read from server.conf and are prefixed by 'mysql_'.
941 - new command: cdt (change database tool)
942 - new command line option: dbtool (choose startup database tool)
943 - The name of current stream is now stored in the database,
944 so paraslash remembers its current stream when restarted.
945 - new command: csp (change stream and play)
946 - para_gui also reports current database tool and server uptime
949 -------------------------------------------
950 0.1.2: (2004-11-28) "spherical fluctuation"
951 -------------------------------------------
953 Point release before the big dbtool changes go in.
955 - dbtool: rename ca to cam (copy all meta data). It now also
956 copies numplayed and lastplayed time as well as the picture
958 - fix endless-loop-bug caused by mp3 files with invalid header
960 -----------------------------------------
961 0.1.1: (2004-11-05) "floating atmosphere"
962 -----------------------------------------
965 - new dbtool command: mbox. Browse your sound-file collection
966 with your favorite mail reader.
967 - several small fixes
969 -------------------------------------
970 0.1.0: (2204-10-22) "rotating cortex"
971 -------------------------------------
973 - fix logging bug for loglevel > VERBOSE
975 - correct timings for vbr mp3s
976 - modular audio format support
977 - ogg-vorbis support (experimental)
978 - new server option: autoplay
980 -----------------------------------------
981 0.0.99: (2004-07-25) "harmonic deviation"
982 -----------------------------------------
984 - rename projectname from icc to paraslash (play, archive, rate
985 and stream large audio sets happily)
986 - paraslash is no longer restricted to one particular audio
988 - new dbtool commands (stradd, strq, strdel) for easy stream
989 managment w/o configuration file. That obsoletes stream_defs
990 file/config option for dbtool.
991 - picadd accepts jpeg data from stdin
992 - new server commands: ps (select previous stream), sc (song change)
993 - new default pictures for sdl_gui
994 - gui: new key_map option for binding commands and internal
995 functions to arbitrary keys, nice help screen, rip out
996 soundcard/linux specific stuff, avoid noise artefacts while jumping,
997 show silly logo on startup
998 - new executables: para_fade for fading volume, para_dbadm for
999 manipulating attributes
1000 - cdb adds _all_ tables to mysql database
1001 - revised and beautified documentation
1002 - sample dbtool rewritten in C
1005 ---------------------------------------------
1006 0.0.98: (2003-12-26) "incremental smoothness"
1007 ---------------------------------------------
1009 - kick icecast in favour of poc. That removes some races and reduces
1010 core code considerably.
1011 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1012 give finer info on afs' status.
1013 - gui can start decoder (see config options). Further new gui
1014 commands: refresh (^L), jmp (F1-F10)
1015 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1016 terminates gui. This fixes dead instances consuming memory
1018 - new dbtool command: verb for sending verbatim sql queries.
1019 - fix pid_list races (by removing pid_list)
1022 --------------------
1023 0.0.97: (2003-10-26)
1024 --------------------
1026 - installation prefix now defaults to /usr/local
1027 - new commands for gui: snozze, sleep and reread config
1028 - config file for gui and sdl_gui
1029 - fix problems with filenames containing funny characters
1030 (reported by Thomas Forell)
1031 - improved signal handling for gui, now it rereads conf on SIGHUP
1032 - new dbtool command: cdb (create database)
1033 - switch from argtable to gengetopt
1034 - major code cleanup and speed improvements
1035 - fix several potential buffer overflows
1036 - many small fixes and cleanups
1042 - easy stream_defs syntax
1043 - sdl_gui can display images associated to the file being played
1044 - Major feature enhancements for icc_gui including dynamic text
1045 placement and the top/bottom window design
1046 - vrfy/clean now also checks for NULL values in attributes as
1047 well as for invalid picture pointers
1048 - fix long outstanding case sensitivity bug
1049 - many small fixes and cleanups
1055 - sdl gui runs much faster
1056 - new dbtool command: ca (copy attributes)
1057 - count and display number of times the song has been played
1058 - new feature: scoring
1059 - command line options for sdl_gui
1060 - simpler syntax of streams file
1061 - decrease network traffic of stat
1063 - many small fixes and cleanups
1069 - new server command: ns (next stream)
1070 - new icc_gui command: c (change stream)
1072 - stat shows also id3 tag info
1074 - log flodding bug fixed
1075 - many small fixes and cleanups
1081 - colors for icc_gui
1082 - icc_gui sets volume directly (linux only)
1083 - proper locking that fixes some races
1084 - fix security bug that caused commands to be executed even
1085 with unsufficient permissions
1086 - new command: hup to make all servers reread their configuration file
1087 - icecast meta data streaming
1088 - many small fixes and cleanups
