4 ---------------------------------------------
5 0.5.2 (to be announced) "orthogonal interior"
6 ---------------------------------------------
7
8 The new sync filter, the AES_CTR128 stream cipher and the overhauled
9 network code are the highlights of this release. It also includes a
10 fair number of smaller fixes and improvements not mentioned here.
11
12 - The new sync filter synchronizes playback between multiple
13 clients.
14 - Connections between para_server and para_client are now
15 encrypted by means of AES rather than RC4 if both sides
16 support it. RC4 is still available as a fallback. This
17 feature is fully transparent, i.e. no command line options
18 are necessary, and a client linked against openssl can
19 speak with a server linked against libgcrypt and vice versa.
20 - Major cleanup of the networking subsystem.
21 - Improvements to para_fade: the new set mode, multi-channel
22 initial volumes, better error logging.
23 - The man pages of para_audiod, para_filter, para_recv, and
24 para_write contain the relevant options for receivers, filters,
25 writers. This broke in 0.5.0.
26 - ogg/vorbis latency improvements.
27 - Improved user manual.
28 - Minor fixes to avoid clang warnings.
29
30 ------------------------------------------
31 0.5.1 (2013-12-20) "temporary implication"
32 ------------------------------------------
33
34 Lots of fixes and improvements all over the place, and a major overhaul
35 of the build system.
36
37 - Audiod improvements and fixes.
38 - Buffer tree robustness improvements.
39 - Cleanup of the mood subsystem.
40 - Fixes and cleanups for the flac decoder.
41 - Latency improvements for the ogg/opus decoder.
42 - Crypto support is now optional. On systems without
43 openssl/gcrypt, the build succeeds but para_server,
44 para_audiod, para_client won't be built.
45 - The build system now works for cross-compile setups.
46 - The dependency tree has been flattened, which speeds up
47 builds and avoids to recreate the man pages on every change.
48 - The error code helper has been rewritten from perl to C,
49 which further improves build time.
50 - Many small bugs in the build system have been identified
51 and fixed.

56 ----------------------------------------
57 0.5.0 (2013-08-23) "invertible validity"
58 ----------------------------------------
59
60 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
61
62 - The sideband compatibility code has been removed, hence
63 sideband connections (introduced in 0.4.11) are now mandatory.
64 - Addblob commands can produce output.
65 - The stat command no longer sends garbage when para_server was
66 compiled against libgcrypt.
67 - Dependencies for gengetopt files are computed automatically.
68 This eliminates a constant source of build bugs.
69 - The setatt command now accepts file name patterns rather than only
70 path names.
71 - overview.pdf is now based on dia, a simple diagram creation program.
72 The new version is much more detailed and contains descriptions of
73 the various programs of the paraslash package.
74 - The separator of all multi-word options has been changed from
75 underscore to dash. For example --log_color becomes --log-color.
76 - Overhauled web pages and the new logo.

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