3
4 ---------------------------------------------
5 0.5.2 (to be announced) "orthogonal interior"
6 ---------------------------------------------
7
8 - The new sync synchronizes playback between multiple clients.
9 - Major cleanup of the networking subsystem.
10 - Minor fixes to avoid clang warnings.
11
12 ------------------------------------------
13 0.5.1 (2013-12-20) "temporary implication"
14 ------------------------------------------
15
16 Lots of fixes and improvements all over the place, and a major overhaul
17 of the build system.
18
19 - Audiod improvements and fixes.
20 - Buffer tree robustness improvements.
21 - Cleanup of the mood subsystem.
22 - Fixes and cleanups for the flac decoder.
23 - Latency improvements for the ogg/opus decoder.
24 - Crypto support is now optional. On systems without
25 openssl/gcrypt, the build succeeds but para_server,
26 para_audiod, para_client won't be built.
27 - The build system now works for cross-compile setups.
28 - The dependency tree has been flattened, which speeds up
29 builds and avoids to recreate the man pages on every change.
30 - The error code helper has been rewritten from perl to C,
31 which further improves build time.
32 - Many small bugs in the build system have been identified
33 and fixed.
34
35 ----------------------------------------
36 0.5.0 (2013-08-23) "invertible validity"
37 ----------------------------------------
38
39 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
40
41 - The sideband compatibility code has been removed, hence
42 sideband connections (introduced in 0.4.11) are now mandatory.
43 - Addblob commands can produce output.
44 - The stat command no longer sends garbage when para_server was
45 compiled against libgcrypt.
46 - Dependencies for gengetopt files are computed automatically.
47 This eliminates a constant source of build bugs.
48 - The setatt command now accepts file name patterns rather than only
49 path names.
50 - overview.pdf is now based on dia, a simple diagram creation program.
51 The new version is much more detailed and contains descriptions of
52 the various programs of the paraslash package.
53 - The separator of all multi-word options has been changed from
54 underscore to dash. For example --log_color becomes --log-color.
55 - Overhauled web pages and the new logo.

57 Downloads: ./releases/paraslash-0.5.0.tar.bz2 (tarball),
58 ./releases/paraslash-0.5.0.tar.bz2.asc (signature)
59
60 --------------------------------------
61 0.4.13 (2013-07-29) "spectral gravity"
62 --------------------------------------
63
64 One more 0.4.x release before the API-breaking changes for 0.5.0 go
65 in. The main features of this release are the ogg/opus audio format,
66 and UTF-8 support, but it includes also tons of other improvements
67 and fixes all over the place.
68
69 - New audio format: ogg/opus.
70 - UTF8 support for para_gui and the mp3 audio format handler.
71 - Scheduler improvements and fixes.
72 - The obsolete gettimeofday() function has been replaced
73 by clock_gettime() on systems which support it.
74 - Speed and usability improvements for para_gui.
75 - para_client now restores the fd flags of stdin and stdout
76 on shutdown.
77 - Improved manual pages.
78 - Consistent version strings for all executables.
79 - Reduced dependencies on generated files result in fewer
80 recompilations on changes.
81 - Performance improvements for the compress filter.
82 - Improved downloads web page.
83
84 -----------------------------------------
85 0.4.12 (2012-12-20) "volatile relativity"
86 -----------------------------------------
87 The new command line player, the resample filter, ALSA support for
88 para_fade, and the improved build system are the highlights of this
89 release which probably marks the end of the 0.4.x series.
90
91 - The afh receiver and the para_play executable.
92 - The resample filter: A sample rate converter based on
93 libsamplerate.
94 - The "versions" directory has been removed from the master
95 branch. The tarballs of the old releases are now available
96 in the new "releases" branch.
97 - Overhaul of the build system: All generated files are now
98 written to the "build" directory.
99 - The modular mixer API and the alsa mixer.
100 - Minor fixes for the osx writer.
101
102 --------------------------------------
103 0.4.11 (2012-07-20) "mutual diversity"
104 --------------------------------------
105
106 The major feature in this release is the new sideband API for
107 client-server communication. This API will be used exclusively starting
108 with 0.5.0, which breaks backward compatibility but allows to get rid
109 of quite some compatibility code. Other noteworthy changes include
110 decoder latency improvements and a long-standing bug fix for the
111 ALSA writer.
112
113 - Sideband connections: If both para_server and para_client
114 support this feature, data is sent as a multiplexed stream.
115 - The --no_default_filters option of para_filter has been
116 removed.
117 - Several fixes and latency improvements to various decoders.
118 - The ALSA writer now limits the prebuffer time to 500ms.
119 - Documentation improvements.
120 - Overhaul of the command_util.sh script.
121 - Fixes for some minor problems found by the clang analyzer.
122 - Compiles (almost) without warnings on gcc-3.
123 - Robustness improvements of the buffer tree code.
124
125 ------------------------------------------
126 0.4.10 (2012-03-30) "heterogeneous vacuum"
127 ------------------------------------------
128
129 Nothing earth-shaking in this release, but quite a few usability
130 improvements and the usual mix of cleanups and fixes.
131
132 - The --no_default_filters option of para_filter has been
133 deprecated. It still works but has no effect and will be
134 removed in the next version.
135 - para_gui now prints also the stderr output of the executing
136 command in the bottom window.
137 - Cleanup and consolidation of the various wrappers for
138 write(), writev(), send() and friends.
139 - The obscure error messages on mmap() failures have been
140 replaced by meaningful messages. This affects mainly
141 para_afh.
142 - para_audioc: Cleanups and memory leak fixes.
143 - Test 0004-server no longer fails if para_server is not
144 being built.
145 - New configure options: --with-id3tag-{headers,libs}.
146
147 -------------------------------------
148 0.4.9 (2011-12-06) "hybrid causality"
149 -------------------------------------
150
151 Support for another audio format, interactive mode for para_client
152 and para_audiod and many small improvements/fixes all over the place.
153
154 - Support for flac, the free lossless audio codec.
155 - Fix for an endless loop in the mp3 decoder for certain
156 (corrupt) mp3 files.
157 - When executed without specifying a command, para_client
158 and para_audioc start an interactive shell (requires
159 libreadline being installed). The interactive mode offers
160 full tab completion and command line history.
161 - autogen.sh now detects a distcc setup and adjusts the
162 parameter for the -j option of make accordingly.
163 - Shared memory areas are no longer restricted to 64K. We now
164 detect the maximal size of a shared memory area at runtime.
165 - cleanup of the internal uptime API.
166 - para_server prefaults the mmapped audio file to avoid
167 delays on slow media.
168 - A new test for the test-suite that exercises the
169 communication between para_server and para_audiod.
170 - The alsa writer eats up less CPU cycles when configured to
171 use the DMIX plugin.
172 - Simplified and unified receiver code.
173 - Makefile cleanups.
174 - Commands which print a list of matching audio files now
175 emit a meaningful error message if no audio file matched the
176 given pattern(s).
177
178 --------------------------------------
179 0.4.8 (2011-08-19) "nested assignment"
180 --------------------------------------
181
182 Gcrypt support, the overhauled osx writer and regex format specifiers
183 are the highlights of this release.
184
185 - support for libgcrypt as a drop-in replacement for openssl.
186 Run configure --enable-cryptolib=gcrypt to link against
187 libgcrypt. The two crypto implementations are compatible to
188 each other, i.e. a para_client executable linked against
189 gcrypt can connect to para_server linked against libssl
190 and vice versa.
191 - Rewrite of the osx writer (output plugin for Mac OS).
192 - audiod: The format specifier for receivers, filters and
193 writers is now treated as a regular expression. This allows
194 to replace 5 lines in the config file (one for each audio
195 format) by one single line. See the manual for details.
196 - The *.cmdline.[ch] files are no longer contained in the released
197 tarballs. This reduces the size of the tarballs but requires
198 gengetopt to build the tarball.
199 - Compiles cleanly also with llvm/clang.
200 - Corrupt mp3 files are handled more gracefully.
201 - The alsa writer uses poll fds instead of computing timeouts.
202 - Cleanup of the generic writer API.
203 - sched: Optimized zero timeouts.
204 - vss timeout cleanups.
205 - oggdec fixes and improvements.
206
207 --------------------------------------
208 0.4.7 (2011-06-01) "infinite rollback"
209 --------------------------------------
210
211 The new ao writer, support for ssh RSA keys and a couple of other
212 enhancements.
213
214 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
215 platforms through the libao audio library.
216 - Support for RSA keys generated with ssh-keygen.
217 - configure: improved options for ogg/vorbis/speex.
218 - The git version reported by --version always matches HEAD.
219 - The autogen script detects the number of processors and
220 runs a parallel make if possible.
221 - Major cleanup of the crypto API.
222 - Documentation updates.
223
224 ------------------------------------------
225 0.4.6 (2011-03-31) "deterministic entropy"
226 ------------------------------------------
227
228 Lots of ogg/vorbis improvements, the new test suite, enhancements
229 for para_gui and a fair amount of other bug fixes.
230
231 - For DCCP/OGG streams the audio file header is only sent once
232 at the beginning of the stream rather than periodically
233 every five seconds. This reduces network traffic and the
234 FEC group size.
235 - The vorbis comment header is replaced by an empty dummy header
236 before the header is sent over the network. This also results in
237 less network traffic and smaller FEC groups.
238 - The new "test" make target allows to perform some sanity checks prior
239 to installing the package.
240 - ogg timing fixes and performance improvements
241 - Scheduler improvements
242 - Proper exit codes for para_write
243 - para_gui: New option --theme to select a startup theme. Several
244 other improvements and fixes.
245 - aacdec error message cleanups
246 - simplified color error handling
247
248 --------------------------------------------
249 0.4.5 (2010-12-17) "symmetric randomization"
250 --------------------------------------------
251
252 Bug fixes, internal cleanups and variable-sized FEC slices.
253
254 - Contains a fix for an invalid-free-bug in the ogg audio format
255 handler code.
256 - Switching off the DCCP sender works again.
257 - para_audiod handles crashes of para_server more robustly.
258 - Internal scheduler and writer cleanups.
259 - Reduced latency due to variable-sized FEC slices.
260 - Improved documentation and error diagnostics.
261 - The build of para_server is now optional, allowing the build
262 to succeed in case libosl is not installed.
263
264 ------------------------------------------
265 0.4.4 (2010-08-06) "persistent regularity"
266 ------------------------------------------
267
268 Support for yet another audio format, para_write improvements and
269 bug fixes.
270
271 - Support for the speex codec.
272 - Support for sample formats other than 16 bit little endian.
273 - error2.h is now created by a perl script which speeds up configure
274 considerably.
275 - Fix a bug in the aac decoder which could lead to segfaults in
276 para_filter/para_audiod.
277 - Fixes for autoconf-2.66.
278
279 ----------------------------------------
280 0.4.3 (2010-07-05) "imaginary radiation"
281 ----------------------------------------
282
283 Many improvements for the DCCP and the UDP transport, the new user
284 manual and the usual mix of bug fixes and internal improvements.
285
286 - FEC support for the DCCP sender (Gerrit Renker). The new
287 --dccp_max_slice_size, --dccp_data_slices_per_group and
288 --dccp_slices_per_group options can be used to set the FEC
289 parameters for the DCCP transport.
290 - DNS lookups for UDP targets (Gerrit Renker).
291 - The new user manual replaces the README, README.afs, REQUIREMENTS
292 and INSTALL documents.
293 - Fix an end-of-file detection bug in the oggdec filter.
294 - The new nonblock API.
295 - Both options of the oggdec filter have been removed.
296 - New debug mode for the internal scheduler.
297
298 ------------------------------------------
299 0.4.2 (2010-04-23) "associative expansion"
300 ------------------------------------------
301
302 It's been some time since the last release, but finally here is
303 paraslash-0.4.2. The bulk of the changes comes from the new buffer
304 tree API, but there are changes all over the tree. Mainly performance
305 and usability improvements, but also quite some bug fixes.
306
307 - The new buffer tree API.
308 - DCCP: Support for CCID negotiation (Gerrit Renker).
309 - UDP robustness fixes.
310 - The --bufsize option for mp3dec is gone as it no longer makes sense
311 for the new buffer tree API.
312 - Fix audible buffer underruns for wma streams.
313 - The alsa writer no longer prints meaningless underrun durations.
314 - audiod: Defaults work also for udp streams. If no filter is
315 given for an audio format that is received via upd, fecdec is
316 automatically added as the first filter (along with the decoder).
317
318 ---------------------------------------
319 0.4.1 (2009-12-22) "concurrent horizon"
320 ---------------------------------------
321
322 Support for another audio format, minor feature enhancements and lots of bug
323 fixes. All fixes that have been accumulated in the maint branch (in particular
324 those mentionened in the 0.3.6 release notes) appear in this release as well.
325
326 - wma support.
327 - new afh option: --human to activate human-readable output.
328 - new server/audiod option: --log-timing to print timing information.
329 - build system improvements.
330 - source code documentation updates.
331
332 -------------------------------------
333 0.3.6 (2009-12-07) "cubic continuity"
334 -------------------------------------
335
336 Quite a few bugs have been found and fixed since 0.3.5, so here's
337 another 0.3.x release. No new features.
338
339 - Always check return value of malloc().
340 - ogg vorbis/FEC: Do not write garbage after the audio file header.
341 - exit if root privileges could not be dropped.
342 - FEC: Fix computation of extra slices.
343 - oss: Fix check for empty input buffer.
344 - Avoid buffer underruns due to filter chain output buffer constraints.
345 - server: Fix assignment of afs_pid.
346 - Don't panic if the afs database contains unknown audio formats.
347 - http/dccp: Do not send the audio file header twice.
348 - FEC: Timing improvements.
349
350 ----------------------------------------------
351 0.4.0 (2009-11-10) "simultaneous independence"
352 ----------------------------------------------
353
354 Two significant changes which require the new version number: The
355 improved authentication dialog and the fact that the database code
356 has been moved to a library, libosl. To use the new version, you have
357 to generate new RSA keys, see INSTALL for details. A shell script is
358 provided for conversion of the 0.3 database to the new 0.4 format.
359
360 - stronger crypto for client authentication
361 - the database code has been moved to a library
362 - improved status item handling
363 - cleanup of the build system
364 - The "-V" option now also prints the git version
365 - the new parser-friendly listing mode for the ls and stat commands
366 - mandatory rc4 encryption
367 - major audio format handler cleanups
368 - (id3,...) tags are no longer stored as a combined string in the database
369 - new mood methods: artist_matches, title_matches, comment_matches,
370 album_matches, year_maches, year.
371
372 --------------------------------------------
373 0.3.5 (2009-09-21) "symplectic separability"
374 --------------------------------------------
375
376 Full client support for *BSD Unixes, complete re-write of the ogg
377 vorbis audio format handler, various improvements all over the place
378 and the usual mix of bugfixes. This release marks the end of the 0.3
379 series if no serious problems show up.
380
381 - the new oss writer (supported on *BSD and Linux)
382 - rewrite of the ogg vorbis audio format handler. It's
383 recommended to replace the chunk tables of existing ogg
384 vorbis files in the afs database by re-adding these files
385 with "add -f".
386 - support for netmask subsets (Gerrit Renker)
387 - the new prebuffer filter
388 - improved signal handling
389 - variable fec output buffer size
390 - improved FEC timing fixes audible buffer underruns in UDP mode
391 - --log_color actually works
392 - new ls option: -d (print dates as seconds after the epoch)
393 - update to gengetopt 2.22.2
394 - support for RSA keys of size > 512 bits
395 - new option "mixer_channel" for para_fade
396
397 -----------------------------------------
398 0.3.4 (2009-05-07) "elliptic inheritance"
399 -----------------------------------------
400
401 The new udp sender, forward error correction, colored logs and various
402 other improvements. As the udp sender does not depend on any special
403 libraries, it is built unconditionally.
404
405 - The udp sender replaces the ortp sender. The new code uses forward
406 error correction to protect against packet losses. Many thanks to
407 Gerrit Renker for providing ipv6 support.
408 - The default port for udp streaming now defaults to 8000, like
409 for the http and the dccp senders/receivers.
410 - Loglevels are now specified as symbolic names, e.g.
411 "--loglevel info".
412 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
413 - para_server/para_audiod: Color support for log messages.
414 - new options for mp3dec: --ignore-crc, --bufsize
415 - new audiod option: --config-file.
416 - gengetopt cleanups.
417 - Improved help/man pages: The documentation of para_audiod,
418 para_recv, para_filter and para_write now also contains
419 all options of the available receivers/filters/writers. The
420 man page of para_fade contains a description of the different
421 modes of operation.
422 - More source code documentation.
423 - vss timing fixes.
424
425 --------------------------------------------
426 0.3.3 (2008-12-01) "axiomatic perspectivity"
427 --------------------------------------------
428
429 Internal code cleanups, bug fixes, improved tag handling and the new
430 amplification filter.
431
432 - para_server uses the generic scheduling code.
433 - overhaul of the virtual streaming system.
434 - mp3: id3 version 2 support via libid3tag (optional)
435 - ogg: vorbis comment support.
436 - aac meta info support.
437 - mp3 audio format handler cleanups.
438 - new filter: "amp" to amplify the amplitude of the audio stream
439 - new status item/database entry: amplification. It is
440 used by the amp filter to pre-amplify the audio stream.
441 - fix a close-without-open bug in para_write.
442 - fix a bug in com_init() which was introduced in 0.3.2.
443 - better error diagnostics for para_client.
444
445 -----------------------------------------
446 0.3.2 (2008-04-11) "probabilistic parity"
447 -----------------------------------------
448
449 The new para_afh executable, scheduling and documentation improvements.
450
451 - new ls option: -lc (list chunk table)
452 - new executable: para_afh, the stand-alone audio file handler tool
453 - afs commands can send output more than SHMMAX (32MB on Linux). This
454 also reduces the memory usage of commands that produce large amounts
455 of output.
456 - major scheduler and audiod cleanups.
457 - more detailed and much nicer man pages.
458
459 ---------------------------------------
460 0.3.1 (2008-02-23) "liquid interaction"
461 ---------------------------------------
462
463 A mix of cleanups, bug fixes, improvements, and some new features. No
464 significant changes to the new database (osl) code, which is generally
465 a good sign.
466
467 - Share some similar/duplicate code between the http and the
468 dccp sender.
469 - Generic access control lists for paraslash senders.
470 - dccp sender: Access control lists, connection limiting and support
471 for the allow,deny,on,off,help sender commands.
472 - The default dccp port changed from 5001 to 8000 (suggested by
473 Gerrit Renker).
474 - para_server starts even if not all public keys could be loaded.
475 - Audiod performance improvements.
476 - fix a bug in the "off" command of the http sender.
477 - fix some fd and memory leaks.
478 - Update to gengetopt-2.22.
479
480 -------------------------------------
481 0.3.0 (2008-01-12) "solar saturation"
482 -------------------------------------
483
484 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
485
486
487 Usually one might expect lots of new features AND a big increase in size
488 for a major release like this.
489
490 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
491 ever. The decrease in size is mostly due to the removal of some
492 graphical tools (which were only quick hacks anyway). But also the
493 fact that the mysql code is gone cuts down the size a bit.
494
495 Being independent of mysql comes at a cost: The fact that paraslash
496 now contains its own database (the object storage layer, osl) increases
497 the (stripped) binary size of para_server by ~50K on i386.
498
499 - no more restrictions on unique basenames.
500 - independent of mysql: The new self-contained object
501 storage layer (osl) replaces the mysql database.
502 - New executable para_fsck: Check integrity of osl tables.
503 - Lyrics support.
504 - Reliable audio file move/rename detection.
505 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
506 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
507 Solaris (sparc64).
508 - the new osl-based audio file selector (afs) replaces the random,
509 the playlist and the mysql selector of paraslash-0.2.x.
510 - IPv6 support (thanks to Gerrit Renker).
511 - paraslash-0.2.x streams are now called "moods". Writing
512 0.3.x-mood definitions should be both easier and more
513 powerful than writing 0.2.x-stream definitions.
514 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
515 been removed. The world is a better place without them. However,
516 para_gui is still there.
517 - afs tracks audio file selection also in playlist mode.
518 - few easy-to-use afs commands replace the many not-so-easy-to-use
519 mysql commands (and are available also in playlist mode).
520 - Improved error subsystem.
521 - The earth-shaking new logo.
522
523 -----------------------------------------
524 0.2.17 (2007-11-20) "isotropic threshold"
525 -----------------------------------------
526
527 Mainly bugfixes and cleanups in this version which marks the end of
528 the 0.2.x series if no serious bugs show up after the release.
529
530 - mysql_selector: fix a locking bug.
531 - universal chunk queueing.
532 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
533 to Gerrit Renker).
534 - be more carful wrt. signed vs. unsigned argument passing.
535 - cleanup error.h and fix some references to invalid error
536 codes.
537 - update to gengetopt-2.21.
538 - update to ortp-0.13.1.
539 - autoconf: extend checks for headers, library functions and
540 compiler characteristics.
541 - Fix streaming of large mp3 files.
542 - Fix an off-by-one bug in playlist handling.
543
544 --------------------------------------
545 0.2.16 (2007-04-05) "neural discharge"
546 --------------------------------------
547
548 The main change in this release is the major audio format handler
549 cleanup which removes some similar/duplicate code and makes it easier
550 to implement plugins for other audio formats. Of course, the usual mix
551 of other improvements/changes/bugfixes also made it into the release.
552
553 - simplified audio format handlers (most of the handling functions
554 were moved one layer up to the virtual streaming system).
555 - para_server uses mmap to read audio files
556 - repositioning of mp3 streams is much faster, in particular for
557 jumping near the end of large mp3 files.
558 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
559 and AFS_WRITE.
560 - fix a bug in para_filter that caused decoding of aac files
561 to start only after a few seconds.
562 - fix osx_writer hangs
563 - simplified dccp code (thanks to Gerrit Renker)
564 - the compress filter works also on big endian systems (ppc)
565
566 -----------------------------------------
567 0.2.15 (2007-02-16) "inductive resonance"
568 -----------------------------------------
569
570 Minor improvements, more documentation and a bunch of bug fixes.
571
572 - para_server: The server.users file is only read once on server
573 startup rather than for each connection
574 - mp3dec: Fix decoding of corrupt mp3 files
575 - afs (audio file sender) is now called vss (virtual streaming
576 system). Consequently, the permission flags specified in
577 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
578 become VSS_READ and VSS_WRITE respectively.
579 - para_audiod/para_filter: Fix a bug that caused the last chunk
580 of audio data not being written under certain circumstances
581 - audiod: compute the difference of server time and local time
582 correctly
583 - para_server/para_audiod: Fix some memory leaks
584 - documentation improvements
585 - configure.ac: fix checks for para_krell
586 - new man pages
587
588 -------------------------------------------
589 0.2.14 (2006-10-15) "transient singularity"
590 -------------------------------------------
591
592 The only major enhancement of this version is the osx writer which completes
593 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
594 until now for reasons beyond the scope of this changelog entry.
595
596 - new output plugin for Mac Os: the osx writer
597 - rename configure command line options from --enable-xxx-headers to
598 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
599 - configure: new command line options: --with-mad-headers,
600 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
601 - some robustness fixes
602 - dymamic audio format recognition for audiod
603 - para_server: new command line option: --autoplay_delay
604 - para_audiod: new command line option: --clock_diff_count
605
606 ---------------------------------------
607 0.2.13 (2006-07-14) "sonic convolution"
608 ---------------------------------------
609
610 A bunch of new features and core changes.
611
612 - the new paraslash scheduler, short and sweet.
613 - Support for m4a/mp4 files via the new aac audio format
614 handler/filter (requires libfaad).
615 - each writer has its own command line parser, just like
616 para_recv and para_filter.
617 - para_client and para_audioc use the error subsystem
618 - writers are integrated in para_audiod (currently linux-only)
619 - para_client is integrated in para_audiod
620 - random/playlist selector: improved info strings
621 - new audiod commands: tasks, kill
622 - update to libortp-0.10.1
623 - para_fade: wake time defaults to 8 hours from now
624 - update to autoconf-2.60
625
626 ------------------------------------------
627 0.2.12 (2006-05-12) "oriented abstraction"
628 ------------------------------------------
629
630 Many user-visible changes in this release and lots of new
631 features:
632
633
634 - the new optional dccp sender/receiver. It uses the datagram
635 congestion control protocol. You'll need a fairly new kernel
636 for this.
637 - paraslash works on Mac OS X (thanks to Gerd Becker)
638 - para_play renamed to para_write
639 - modular output plugin design (writers) for para_write
640 - new file_writer output plugin for para_write
641 - compress filter speed improvements
642 - update to libortp-0.9.1
643 - update to gengetopt-2.17rc
644 - para_client no longer depends on libreadline (as the
645 code for the interactive mode was removed).
646 - gcc-2-95 is no longer a supported compiler. It may still
647 work, but it gets no more testing.
648 - the tarball no longer contains the screenshot images which
649 reduces its size quite a bit.
650 - configure: new command line options: --enable-mysql-headers
651 and --enable-mysql-libs
652
653 ------------------------------------
654 0.2.11 (2006-03-11) "atomic duality"
655 ------------------------------------
656
657 Here it is, the first paraslash release developed with git. There
658 are fairly many user-visible changes in this release. As two out of
659 the three "database tools" of paraslash don't use a database at all,
660 they are now called "audio file selectors" instead.
661
662
663 - the cdt command (change database tool) becomes chs (change
664 selector)
665 - no more colon separators: The syntax of some options of
666 para_audiod and para_filter have changed. Use --help for
667 more info (and some examples).
668 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
669 - switch from cvs to git (should've done that earlier)
670 - the new ipc subsystem
671 - new audio file selector: playlist
672 - para_server: the dopey selector is now called "random",
673 and is the default selector. Use the --selector option to
674 choose another selector at startup, or the chs command to
675 change the selector at runtime.
676 - X86_64 fixes (thanks to Steffen Klassert)
677 - para_play fixes
678
679 --------------------------------------
680 0.2.10 (2006-02-17) "cyclic attractor"
681 --------------------------------------
682
683 Huge documentation update, a scrollable window for para_gui, ortp
684 improvements, and of course many small fixes not mentioned here.
685 The diffstat below is rather misleading as most insertions are due
686 to the new source documentation.
687
688 - autoconf cleanup
689 - para_server also uses the new error subsystem
690 - lots of new documentation (UTSL)
691 - gui improvements:
692 - keysyms for cursor keys and for next/previous page keys
693 - scrollable output window
694 - new internal commands: scroll up/down, page up/down
695 - fix color of command output.
696 - ortp: the --chunk_time and --header flags are no longer needed
697 for para_recv/para_audiod as this information is now encoded in
698 each rtp packet sent by para_server.
699
700 -------------------------------------------
701 0.2.9 (2006-01-24) "progressive turbulence"
702 -------------------------------------------
703
704 Internal audiod receivers/filters, the new error subsystem and
705 a lot of small improvements.
706
707 - para_recv and para_filter are integrated into the para_audiod
708 binary, i.e. audiod no longer spawns a new process for
709 each receiver/filter. As para_recv and para_filter might be
710 useful as standalone programs, they still get built (linked
711 against the same object files that are also used for audiod).
712 - further ortp timing improvements should reduce the CPU usage
713 of the ortp receiver.
714 - improved audio grabbing. The 'grab' command of para_audiod
715 has its own set of command line options. Read the output of
716 "para_audioc help grab" for more info.
717 - oggdec: configurable input prebuffer size.
718 - the new error subsystem gives better error diagnostics
719 and reduces code size.
720
721 -----------------------------------------
722 0.2.8 (2006-01-02) "dynamic accumulation"
723 -----------------------------------------
724
725 The new modular filter design and the para_play-hangs bugfix.
726
727 - new executable: para_filter. It combines para_mp3dec,
728 para_oggdec and para_compress. It also adds a further filter
729 type, wav, that just inserts a wave header at the desired point
730 of the filter chain. All 'piping' is done in-memory (i.e. no
731 read/write operations are used).
732 - para_play: fix a stupid bug that caused it to hang under
733 certain circumstances.
734
735 -------------------------------------------
736 0.2.7 (2006-12-27) "transparent invariance"
737 -------------------------------------------
738
739 Not many user-visible changes but a fair amount of internal improvements.
740
741
742 - The http sender buffers data if it can not be sent
743 out immediately (because the socket is not writable). This
744 should prevent para_server from shutting down the connection
745 too early on a loaded network.
746 - para_play also prebuffers data if it is told to start at a
747 future time by the --start_time option.
748 - The return of para_recv: It combines para_ortp_recv and
749 para_http_recv. Use the --receiver option to switch between
750 the two. para_recv builds without libortp, but contains
751 only the http receiver in this case.
752 - update to ortp 0.8.1. As this ortp release contains incompatible
753 changes, para_recv-0.2.7 won't link against older ortp libs.
754 - improved ortp timings.
755 - use of gcc-extensions that #define away for non-gcc and
756 gcc < 3.0.
757
758 -------------------------------------------
759 0.2.6 (2005-10-29) "recursive compensation"
760 -------------------------------------------
761
762 Transparent session encryption (uses openssl's Alleged RC4 cipher),
763 the internal find command and several other improvements and cleanups.
764
765 - Encrypt the session if encryption is requested by the client
766 (default for para_client 0.2.6). This is backwards
767 compatible, so older clients can still connect to para_server
768 0.2.6. Use the new client option --plain to request an
769 uncrypted session (off by default, must be set to on in
770 order to connect to para_server 0.2.x with 0 <= x <= 5).
771 - para_server uses an internal function to locate audio files
772 rather than calling find(1). The server option
773 --mysql_audio_file_dir replaces --mysql_find_cmd.
774 - documentation update
775 - man pages
776 - header file cleanup
777 - para_client code cleanup
778 - para_gui: faster display of output of display commands
779
780 ------------------------------------------
781 0.2.5 (2005-10-13) "aggressive resolution"
782 ------------------------------------------
783
784 This release adds internal senders, i.e. no more external programs are
785 spawned for sending out the audio data. There are two different senders
786 available: The http sender and the ortp sender (former para_send which
787 is no longer needed).
788
789 The new sender code has a plugin-like design so it can be easily
790 extended should there be be any future need for supporting another
791 network streaming protocol. All senders are completely independent of
792 each other. In particular, the http and the ortp sender can operate
793 in parallel.
794
795 - new server command: sender to control senders at runtime.
796 Read the output of "para_server -h" and "para_client help
797 sender" for more information.
798 - para_recv renamed to para_ortp_recv
799 - new executable: para_http_recv, a simple command line
800 http receiver.
801 - major afs/mp3/ogg code simplifications due to internal
802 senders.
803 - ogg timing improvements
804 - fix several minor memory leaks (found by valgrind)
805 - empty stream definitions work again
806 - com_ne(): ignore errors on remove
807 - audiod: fix segfault on server restart
808
809 ---------------------------------------
810 0.2.4 (2005-09-21) "toxic anticipation"
811 ---------------------------------------
812
813 Several small improvements, fixes and the new grab command.
814
815 - audiod:
816 - new command: "grab" to grab the output of the stream reader
817 or any filters. Read the output of "para_audioc help grab"
818 for more information.
819 - fix memory leak
820 - code cleanup
821 - audioc: new command line option: --bufsize to specify a
822 buffer size different from the default size 8192.
823 - improved error diagnostics for para_play.
824 - new configure option: --enable-ssldir so search for openssl in
825 non-standard places
826 - sdl_gui: Make it look nice again for 1024x768
827 - server: report total size of memory allocated with sbrk by malloc,
828 new command line option: --announce_time
829
830 -----------------------------------------
831 0.2.3 (2005-09-01) "hydrophilic movement"
832 -----------------------------------------
833
834 Two new executables and major feature enhancements.
835
836 - audiod filters: It is now possible to specify arbitrary many
837 (including none) filters for each supported audio
838 format. This can be used e.g. for normalizing volume,
839 transforming or grabbing the audio stream, or for using
840 visualizers. Read the output of "para_audiod -h" for the
841 syntax of the new --filter_cmd option.
842 - new executable: para_play, a tiny alsa player. It
843 can play wave files or raw pcm (16 bit little endian)
844 from stdin.
845 - new executable: para_compress, a dynamic range compressor
846 intended to keep audio output at a consistent volume. Derived
847 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
848 - audiod: New option: --stream_delay. This can be used in
849 a local network to syncronize the audio output of all
850 clients that play the same stream.
851
852 ------------------------------------------
853 0.2.2 (2005-08-19) "tangential excitation"
854 ------------------------------------------
855
856 Mostly internal changes in this release, but also some new commands
857 for the mysql database tool.
858
859 - cleanup exec.c, fix para_exec bug
860 - compile time loglevel (log messages below the given level
861 won't be compiled in, which reduces the size of the
862 resulting binaries)
863 - new log macros that shorten the size of the source code.
864 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
865 to send only zeros. With this workaround, para_audioc works
866 again.
867 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
868 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
869 (new entry), "snp" (set numplayed). Read the manual for more
870 information.
871
872 ---------------------------------------
873 0.2.1 (2005-08-15) "surreal experience"
874 ---------------------------------------
875
876 Here comes paraslash-0.2.1. It contains a couple of new features and,
877 surprise, only minor bug fixes.
878
879 - kill noisy mp3 debug message
880 - cleanup of the build system
881 - para_server and para_client directly use the crypto routines
882 of the openssl library rather than invoking the openssl command
883 line utitlity
884 - server/audiod: new option --user to switch to the given user
885 when invoked as root. Read the output of "para_server -h" for
886 more information.
887 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
888 status. Default: "para_audioc stat"
889 - sdl_gui: new option --pic_cmd to be used to download the picture.
890 Default: "para_client pic"
891 - audiod: 5 slots ought to be enough for everybody
892 - audiod: new status item: Uptime, kill hup command
893
894 ------------------------------------------
895 0.2.0 (2005-08-06) "distributed diffusion"
896 ------------------------------------------
897
898 After several month of increased development activity, paraslash-0.2.0
899 has arrived. It contains many new features and is much more
900 self-contained than the old 0.1.x series. Enjoy!
901
902
903 - para_server: fix hang on song change and crash on sighup.
904 Speed up mysql queries. The DIR_LIKE macro is gone.
905 - new executables: para_audiod, the local audio daemon that
906 starts playback (uses SCM_CREDENTIALS socket magic) and
907 para_audioc, the corresponding client.
908 - new executables: para_mp3dec/para_oggdec, two really teensy
909 decoders. para_mp3dec is based on libmad, para_oggdec requires
910 libvorbisfile.
911 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
912 they are now called para_send and para_recv respectively.
913 - documentation updates
914 - para_gui is themable. For now there is the default theme that
915 looks as before and the simple theme: blue and easy.
916 - gui: audio streaming is now handled by audiod. Time display shows
917 playback time rather than streaming time
918 - slider: update to libzmw-0.2.0
919 - para_krell: fix crash on server shutdown
920 - switch from gzip to bzip2
921
922 ----------------------------------------
923 0.1.7 (2005-04-18) "melting penetration"
924 ----------------------------------------
925
926 The main change in this release is clearly the oggvorbis rewrite,
927 but there are also lots of smaller changes. If you intend to use both
928 the mp3 and the ogg plugin, it is recommended to use software mixing,
929 e.g. the dmix plugin which is provided by ALSA.
930
931 - new executables: para_ovsend and para_ovrecv for sending/receiving
932 oggvorbis files via rtp. Requires the open rtp library. Get it at
933 http://www.linphone.org/ortp/
934 - rewrite of the ogg_vorbis core code
935 - configure detects libzmw and, if detected, includes
936 para_slider to the list of binaries to be built by make
937 - server stream writers read from their associated fifo rather
938 than from stdin
939 - slider: two new sliders, lastplayed and numplayed
940 - fix nasty double free bug which caused random segfaults in case of
941 mp3 files with invalid header information
942 - gui: new command line option: --stream_timeout=seconds to
943 deactivate a slot if it is idle for that many seconds (default=`5')
944 - diffstats
945
946 ---------------------------------------
947 0.1.6 (2005-03-05) "asymptotic balance"
948 ---------------------------------------
949
950 Only little user-visible changes in this release. Mainly bugfixes and
951 core code cleanup. This is probably the most stable version ever if you
952 stick to mp3...
953
954 - fix several memory leaks
955 - rename default name of mysql database from "music" to "paraslash".
956 Use para_server's --mysql_database option if you do not want to
957 rename your old database.
958 - rework ogg vorbis code
959 - make update command work on mysql servers with LOCAL_INFILE
960 disabled
961 - gui: improved stream I/O (slots)
962 - simplified audio format API
963 - para_pob_ogg is gone
964
965 ------------------------------------
966 0.1.5 (2004-12-31) "opaque eternity"
967 ------------------------------------
968
969 Let's slide gently into the new year.
970
971 - new: para_slider (not built automatically, type "make
972 para_slider" to build). A toy for those who always felt that
973 creating stream definitions is difficult. See screenshots,
974 README and FEATURES for more info.
975 - improved signal handling. Fixes server segfault on SIGHUP
976 for linux kernels newer than Aug 24 2004 and makes para_gui
977 race-free.
978 - reload database tool on SIGHUP
979 - improved help message for sl
980 - do not log "broken pipe" messages as errors. They are
981 perfectly ok.
982 - fix wrong error message on permission errors
983
984 -----------------------------------------
985 0.1.4 (2004-12-19) "tunneling transition"
986 -----------------------------------------
987
988 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
989 Hopefully, most of them got wiped out with this release. Some
990 enhancements went also in.
991
992 - improved error diagnostics for all commands
993 - stradd/picadd: overwrite previous contents if entry already
994 exists, rather than returning errors
995 - stradd: use current stream if invoked without args
996 - faster (and hopefully more stable) ogg-vorbis handling
997 - para_krell: reap children to avoid zombie-flooding in case
998 no server is running
999 - si: report also server pid
1000 - server: don't busy-loop if dbtool reports only invalid files.
1001 - gui: CTRL+C works again, fix stream_read command line option
1002 - fix pic_add, hist
1003 - fix mysql dbtool startup in case no database exists
1004 - many small fixes and cleanups
1005
1006 ---------------------------------------
1007 0.1.3: (2004-12-10) "vanishing inertia"
1008 ---------------------------------------
1009
1010 Starting from this release, the database tools are integrated in the
1011 server binary. This decreases server startup time, reduces code size
1012 and speeds up database commands. However, the layout of the underlying
1013 mysql database changed only slightly and 0.1.3 should be backwards
1014 compatible in that respect.
1015
1016 Visible changes:
1017
1018 - If mysql is not detected at compile time, or fails to init
1019 at runtime, fall back to the dopey database tool which should
1020 always work.
1021 - para_dbtool and dbtool.conf are gone. All mysql specific
1022 options are read from server.conf and are prefixed by 'mysql_'.
1023 - new command: cdt (change database tool)
1024 - new command line option: dbtool (choose startup database tool)
1025 - The name of current stream is now stored in the database,
1026 so paraslash remembers its current stream when restarted.
1027 - new command: csp (change stream and play)
1028 - para_gui also reports current database tool and server uptime
1029
1030 -------------------------------------------
1031 0.1.2: (2004-11-28) "spherical fluctuation"
1032 -------------------------------------------
1033
1034 Point release before the big dbtool changes go in.
1035
1036 - dbtool: rename ca to cam (copy all meta data). It now also
1037 copies numplayed and lastplayed time as well as the picture
1038 id.
1039 - fix endless-loop-bug caused by mp3 files with invalid header
1040
1041 -----------------------------------------
1042 0.1.1: (2004-11-05) "floating atmosphere"
1043 -----------------------------------------
1044
1045 - gkrellm plugin
1046 - new dbtool command: mbox. Browse your sound-file collection
1047 with your favorite mail reader.
1048 - several small fixes
1049
1050 -------------------------------------
1051 0.1.0: (2004-10-22) "rotating cortex"
