5 0.5.2 (???) "orthogonal interior"
6 ---------------------------------
7
8 - Minor fixes to avoid clang warnings.
9
10 ------------------------------------------
11 0.5.1 (2013-12-20) "temporary implication"
12 ------------------------------------------
13
14 Lots of fixes and improvements all over the place, and a major overhaul
15 of the build system.
16
17 - Audiod improvements and fixes.
18 - Buffer tree robustness improvements.
19 - Cleanup of the mood subsystem.
20 - Fixes and cleanups for the flac decoder.
21 - Latency improvements for the ogg/opus decoder.
22 - Crypto support is now optional. On systems without
23 openssl/gcrypt, the build succeeds but para_server,
24 para_audiod, para_client won't be built.
25 - The build system now works for cross-compile setups.
26 - The dependency tree has been flattened, which speeds up
27 builds and avoids to recreate the man pages on every change.
28 - The error code helper has been rewritten from perl to C,
29 which further improves build time.
30 - Many small bugs in the build system have been identified
31 and fixed.

37 0.5.0 (2013-08-23) "invertible validity"
38 ----------------------------------------
39
40 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
41
42 - The sideband compatibility code has been removed, hence
43 sideband connections (introduced in 0.4.11) are now mandatory.
44 - Addblob commands can produce output.
45 - The stat command no longer sends garbage when para_server was
46 compiled against libgcrypt.
47 - Dependencies for gengetopt files are computed automatically.
48 This eliminates a constant source of build bugs.
49 - The setatt command now accepts file name patterns rather than only
50 path names.
51 - overview.pdf is now based on dia, a simple diagram creation program.
52 The new version is much more detailed and contains descriptions of
53 the various programs of the paraslash package.
54 - The separator of all multi-word options has been changed from
55 underscore to dash. For example --log_color becomes --log-color.
56 - Overhauled web pages and the new logo.

61 --------------------------------------
62 0.4.13 (2013-07-29) "spectral gravity"
63 --------------------------------------
64
65 One more 0.4.x release before the API-breaking changes for 0.5.0 go
66 in. The main features of this release are the ogg/opus audio format,
67 and UTF-8 support, but it includes also tons of other improvements
68 and fixes all over the place.
69
70 - New audio format: ogg/opus.
71 - UTF8 support for para_gui and the mp3 audio format handler.
72 - Scheduler improvements and fixes.
73 - The obsolete gettimeofday() function has been replaced
74 by clock_gettime() on systems which support it.
75 - Speed and usability improvements for para_gui.
76 - para_client now restores the fd flags of stdin and stdout
77 on shutdown.
78 - Improved manual pages.
79 - Consistent version strings for all executables.
80 - Reduced dependencies on generated files result in fewer
81 recompilations on changes.
82 - Performance improvements for the compress filter.
83 - Improved downloads web page.
84
85 -----------------------------------------
86 0.4.12 (2012-12-20) "volatile relativity"
87 -----------------------------------------
88 The new command line player, the resample filter, ALSA support for
89 para_fade, and the improved build system are the highlights of this
90 release which probably marks the end of the 0.4.x series.
91
92 - The afh receiver and the para_play executable.
93 - The resample filter: A sample rate converter based on
94 libsamplerate.
95 - The "versions" directory has been removed from the master
96 branch. The tarballs of the old releases are now available
97 in the new "releases" branch.
98 - Overhaul of the build system: All generated files are now
99 written to the "build" directory.
100 - The modular mixer API and the alsa mixer.
101 - Minor fixes for the osx writer.
102
103 --------------------------------------
104 0.4.11 (2012-07-20) "mutual diversity"
105 --------------------------------------
106
107 The major feature in this release is the new sideband API for
108 client-server communication. This API will be used exclusively starting
109 with 0.5.0, which breaks backward compatibility but allows to get rid
110 of quite some compatibility code. Other noteworthy changes include
111 decoder latency improvements and a long-standing bug fix for the
112 ALSA writer.
113
114 - Sideband connections: If both para_server and para_client
115 support this feature, data is sent as a multiplexed stream.
116 - The --no_default_filters option of para_filter has been
117 removed.
118 - Several fixes and latency improvements to various decoders.
119 - The ALSA writer now limits the prebuffer time to 500ms.
120 - Documentation improvements.
121 - Overhaul of the command_util.sh script.
122 - Fixes for some minor problems found by the clang analyzer.
123 - Compiles (almost) without warnings on gcc-3.
124 - Robustness improvements of the buffer tree code.
125
126 ------------------------------------------
127 0.4.10 (2012-03-30) "heterogeneous vacuum"
128 ------------------------------------------
129
130 Nothing earth-shaking in this release, but quite a few usability
131 improvements and the usual mix of cleanups and fixes.
132
133 - The --no_default_filters option of para_filter has been
134 deprecated. It still works but has no effect and will be
135 removed in the next version.
136 - para_gui now prints also the stderr output of the executing
137 command in the bottom window.
138 - Cleanup and consolidation of the various wrappers for
139 write(), writev(), send() and friends.
140 - The obscure error messages on mmap() failures have been
141 replaced by meaningful messages. This affects mainly
142 para_afh.
143 - para_audioc: Cleanups and memory leak fixes.
144 - Test 0004-server no longer fails if para_server is not
145 being built.
146 - New configure options: --with-id3tag-{headers,libs}.
147
148 -------------------------------------
149 0.4.9 (2011-12-06) "hybrid causality"
150 -------------------------------------
151
152 Support for another audio format, interactive mode for para_client
153 and para_audiod and many small improvements/fixes all over the place.
154
155 - Support for flac, the free lossless audio codec.
156 - Fix for an endless loop in the mp3 decoder for certain
157 (corrupt) mp3 files.
158 - When executed without specifying a command, para_client
159 and para_audioc start an interactive shell (requires
160 libreadline being installed). The interactive mode offers
161 full tab completion and command line history.
162 - autogen.sh now detects a distcc setup and adjusts the
163 parameter for the -j option of make accordingly.
164 - Shared memory areas are no longer restricted to 64K. We now
165 detect the maximal size of a shared memory area at runtime.
166 - cleanup of the internal uptime API.
167 - para_server prefaults the mmapped audio file to avoid
168 delays on slow media.
169 - A new test for the test-suite that exercises the
170 communication between para_server and para_audiod.
171 - The alsa writer eats up less CPU cycles when configured to
172 use the DMIX plugin.
173 - Simplified and unified receiver code.
174 - Makefile cleanups.
175 - Commands which print a list of matching audio files now
176 emit a meaningful error message if no audio file matched the
177 given pattern(s).
178
179 --------------------------------------
180 0.4.8 (2011-08-19) "nested assignment"
181 --------------------------------------
182
183 Gcrypt support, the overhauled osx writer and regex format specifiers
184 are the highlights of this release.
185
186 - support for libgcrypt as a drop-in replacement for openssl.
187 Run configure --enable-cryptolib=gcrypt to link against
188 libgcrypt. The two crypto implementations are compatible to
189 each other, i.e. a para_client executable linked against
190 gcrypt can connect to para_server linked against libssl
191 and vice versa.
192 - Rewrite of the osx writer (output plugin for Mac OS).
193 - audiod: The format specifier for receivers, filters and
194 writers is now treated as a regular expression. This allows
195 to replace 5 lines in the config file (one for each audio
196 format) by one single line. See the manual for details.
197 - The *.cmdline.[ch] files are no longer contained in the released
198 tarballs. This reduces the size of the tarballs but requires
199 gengetopt to build the tarball.
200 - Compiles cleanly also with llvm/clang.
201 - Corrupt mp3 files are handled more gracefully.
202 - The alsa writer uses poll fds instead of computing timeouts.
203 - Cleanup of the generic writer API.
204 - sched: Optimized zero timeouts.
205 - vss timeout cleanups.
206 - oggdec fixes and improvements.
207
208 --------------------------------------
209 0.4.7 (2011-06-01) "infinite rollback"
210 --------------------------------------
211
212 The new ao writer, support for ssh RSA keys and a couple of other
213 enhancements.
214
215 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
216 platforms through the libao audio library.
217 - Support for RSA keys generated with ssh-keygen.
218 - configure: improved options for ogg/vorbis/speex.
219 - The git version reported by --version always matches HEAD.
220 - The autogen script detects the number of processors and
221 runs a parallel make if possible.
222 - Major cleanup of the crypto API.
223 - Documentation updates.
224
225 ------------------------------------------
226 0.4.6 (2011-03-31) "deterministic entropy"
227 ------------------------------------------
228
229 Lots of ogg/vorbis improvements, the new test suite, enhancements
230 for para_gui and a fair amount of other bug fixes.
231
232 - For DCCP/OGG streams the audio file header is only sent once
233 at the beginning of the stream rather than periodically
234 every five seconds. This reduces network traffic and the
235 FEC group size.
236 - The vorbis comment header is replaced by an empty dummy header
237 before the header is sent over the network. This also results in
238 less network traffic and smaller FEC groups.
239 - The new "test" make target allows to perform some sanity checks prior
240 to installing the package.
241 - ogg timing fixes and performance improvements
242 - Scheduler improvements
243 - Proper exit codes for para_write
244 - para_gui: New option --theme to select a startup theme. Several
245 other improvements and fixes.
246 - aacdec error message cleanups
247 - simplified color error handling
248
249 --------------------------------------------
250 0.4.5 (2010-12-17) "symmetric randomization"
251 --------------------------------------------
252
253 Bug fixes, internal cleanups and variable-sized FEC slices.
254
255 - Contains a fix for an invalid-free-bug in the ogg audio format
256 handler code.
257 - Switching off the DCCP sender works again.
258 - para_audiod handles crashes of para_server more robustly.
259 - Internal scheduler and writer cleanups.
260 - Reduced latency due to variable-sized FEC slices.
261 - Improved documentation and error diagnostics.
262 - The build of para_server is now optional, allowing the build
263 to succeed in case libosl is not installed.
264
265 ------------------------------------------
266 0.4.4 (2010-08-06) "persistent regularity"
267 ------------------------------------------
268
269 Support for yet another audio format, para_write improvements and
270 bug fixes.
271
272 - Support for the speex codec.
273 - Support for sample formats other than 16 bit little endian.
274 - error2.h is now created by a perl script which speeds up configure
275 considerably.
276 - Fix a bug in the aac decoder which could lead to segfaults in
277 para_filter/para_audiod.
278 - Fixes for autoconf-2.66.
279
280 ----------------------------------------
281 0.4.3 (2010-07-05) "imaginary radiation"
282 ----------------------------------------
283
284 Many improvements for the DCCP and the UDP transport, the new user
285 manual and the usual mix of bug fixes and internal improvements.
286
287 - FEC support for the DCCP sender (Gerrit Renker). The new
288 --dccp_max_slice_size, --dccp_data_slices_per_group and
289 --dccp_slices_per_group options can be used to set the FEC
290 parameters for the DCCP transport.
291 - DNS lookups for UDP targets (Gerrit Renker).
292 - The new user manual replaces the README, README.afs, REQUIREMENTS
293 and INSTALL documents.
294 - Fix an end-of-file detection bug in the oggdec filter.
295 - The new nonblock API.
296 - Both options of the oggdec filter have been removed.
297 - New debug mode for the internal scheduler.
298
299 ------------------------------------------
300 0.4.2 (2010-04-23) "associative expansion"
301 ------------------------------------------
302
303 It's been some time since the last release, but finally here is
304 paraslash-0.4.2. The bulk of the changes comes from the new buffer
305 tree API, but there are changes all over the tree. Mainly performance
306 and usability improvements, but also quite some bug fixes.
307
308 - The new buffer tree API.
309 - DCCP: Support for CCID negotiation (Gerrit Renker).
310 - UDP robustness fixes.
311 - The --bufsize option for mp3dec is gone as it no longer makes sense
312 for the new buffer tree API.
313 - Fix audible buffer underruns for wma streams.
314 - The alsa writer no longer prints meaningless underrun durations.
315 - audiod: Defaults work also for udp streams. If no filter is
316 given for an audio format that is received via upd, fecdec is
317 automatically added as the first filter (along with the decoder).
318
319 ---------------------------------------
320 0.4.1 (2009-12-22) "concurrent horizon"
321 ---------------------------------------
322
323 Support for another audio format, minor feature enhancements and lots of bug
324 fixes. All fixes that have been accumulated in the maint branch (in particular
325 those mentionened in the 0.3.6 release notes) appear in this release as well.
326
327 - wma support.
328 - new afh option: --human to activate human-readable output.
329 - new server/audiod option: --log-timing to print timing information.
330 - build system improvements.
331 - source code documentation updates.
332
333 -------------------------------------
334 0.3.6 (2009-12-07) "cubic continuity"
335 -------------------------------------
336
337 Quite a few bugs have been found and fixed since 0.3.5, so here's
338 another 0.3.x release. No new features.
339
340 - Always check return value of malloc().
341 - ogg vorbis/FEC: Do not write garbage after the audio file header.
342 - exit if root privileges could not be dropped.
343 - FEC: Fix computation of extra slices.
344 - oss: Fix check for empty input buffer.
345 - Avoid buffer underruns due to filter chain output buffer constraints.
346 - server: Fix assignment of afs_pid.
347 - Don't panic if the afs database contains unknown audio formats.
348 - http/dccp: Do not send the audio file header twice.
349 - FEC: Timing improvements.
350
351 ----------------------------------------------
352 0.4.0 (2009-11-10) "simultaneous independence"
353 ----------------------------------------------
354
355 Two significant changes which require the new version number: The
356 improved authentication dialog and the fact that the database code
357 has been moved to a library, libosl. To use the new version, you have
358 to generate new RSA keys, see INSTALL for details. A shell script is
359 provided for conversion of the 0.3 database to the new 0.4 format.
360
361 - stronger crypto for client authentication
362 - the database code has been moved to a library
363 - improved status item handling
364 - cleanup of the build system
365 - The "-V" option now also prints the git version
366 - the new parser-friendly listing mode for the ls and stat commands
367 - mandatory rc4 encryption
368 - major audio format handler cleanups
369 - (id3,...) tags are no longer stored as a combined string in the database
370 - new mood methods: artist_matches, title_matches, comment_matches,
371 album_matches, year_maches, year.
372
373 --------------------------------------------
374 0.3.5 (2009-09-21) "symplectic separability"
375 --------------------------------------------
376
377 Full client support for *BSD Unixes, complete re-write of the ogg
378 vorbis audio format handler, various improvements all over the place
379 and the usual mix of bugfixes. This release marks the end of the 0.3
380 series if no serious problems show up.
381
382 - the new oss writer (supported on *BSD and Linux)
383 - rewrite of the ogg vorbis audio format handler. It's
384 recommended to replace the chunk tables of existing ogg
385 vorbis files in the afs database by re-adding these files
386 with "add -f".
387 - support for netmask subsets (Gerrit Renker)
388 - the new prebuffer filter
389 - improved signal handling
390 - variable fec output buffer size
391 - improved FEC timing fixes audible buffer underruns in UDP mode
392 - --log_color actually works
393 - new ls option: -d (print dates as seconds after the epoch)
394 - update to gengetopt 2.22.2
395 - support for RSA keys of size > 512 bits
396 - new option "mixer_channel" for para_fade
397
398 -----------------------------------------
399 0.3.4 (2009-05-07) "elliptic inheritance"
400 -----------------------------------------
401
402 The new udp sender, forward error correction, colored logs and various
403 other improvements. As the udp sender does not depend on any special
404 libraries, it is built unconditionally.
405
406 - The udp sender replaces the ortp sender. The new code uses forward
407 error correction to protect against packet losses. Many thanks to
408 Gerrit Renker for providing ipv6 support.
409 - The default port for udp streaming now defaults to 8000, like
410 for the http and the dccp senders/receivers.
411 - Loglevels are now specified as symbolic names, e.g.
412 "--loglevel info".
413 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
414 - para_server/para_audiod: Color support for log messages.
415 - new options for mp3dec: --ignore-crc, --bufsize
416 - new audiod option: --config-file.
417 - gengetopt cleanups.
418 - Improved help/man pages: The documentation of para_audiod,
419 para_recv, para_filter and para_write now also contains
420 all options of the available receivers/filters/writers. The
421 man page of para_fade contains a description of the different
422 modes of operation.
423 - More source code documentation.
424 - vss timing fixes.
425
426 --------------------------------------------
427 0.3.3 (2008-12-01) "axiomatic perspectivity"
428 --------------------------------------------
429
430 Internal code cleanups, bug fixes, improved tag handling and the new
431 amplification filter.
432
433 - para_server uses the generic scheduling code.
434 - overhaul of the virtual streaming system.
435 - mp3: id3 version 2 support via libid3tag (optional)
436 - ogg: vorbis comment support.
437 - aac meta info support.
438 - mp3 audio format handler cleanups.
439 - new filter: "amp" to amplify the amplitude of the audio stream
440 - new status item/database entry: amplification. It is
441 used by the amp filter to pre-amplify the audio stream.
442 - fix a close-without-open bug in para_write.
443 - fix a bug in com_init() which was introduced in 0.3.2.
444 - better error diagnostics for para_client.
445
446 -----------------------------------------
447 0.3.2 (2008-04-11) "probabilistic parity"
448 -----------------------------------------
449
450 The new para_afh executable, scheduling and documentation improvements.
451
452 - new ls option: -lc (list chunk table)
453 - new executable: para_afh, the stand-alone audio file handler tool
454 - afs commands can send output more than SHMMAX (32MB on Linux). This
455 also reduces the memory usage of commands that produce large amounts
456 of output.
457 - major scheduler and audiod cleanups.
458 - more detailed and much nicer man pages.
459
460 ---------------------------------------
461 0.3.1 (2008-02-23) "liquid interaction"
462 ---------------------------------------
463
464 A mix of cleanups, bug fixes, improvements, and some new features. No
465 significant changes to the new database (osl) code, which is generally
466 a good sign.
467
468 - Share some similar/duplicate code between the http and the
469 dccp sender.
470 - Generic access control lists for paraslash senders.
471 - dccp sender: Access control lists, connection limiting and support
472 for the allow,deny,on,off,help sender commands.
473 - The default dccp port changed from 5001 to 8000 (suggested by
474 Gerrit Renker).
475 - para_server starts even if not all public keys could be loaded.
476 - Audiod performance improvements.
477 - fix a bug in the "off" command of the http sender.
478 - fix some fd and memory leaks.
479 - Update to gengetopt-2.22.
480
481 -------------------------------------
482 0.3.0 (2008-01-12) "solar saturation"
483 -------------------------------------
484
485 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
486
487
488 Usually one might expect lots of new features AND a big increase in size
489 for a major release like this.
490
491 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
492 ever. The decrease in size is mostly due to the removal of some
493 graphical tools (which were only quick hacks anyway). But also the
494 fact that the mysql code is gone cuts down the size a bit.
495
496 Being independent of mysql comes at a cost: The fact that paraslash
497 now contains its own database (the object storage layer, osl) increases
498 the (stripped) binary size of para_server by ~50K on i386.
499
500 - no more restrictions on unique basenames.
501 - independent of mysql: The new self-contained object
502 storage layer (osl) replaces the mysql database.
503 - New executable para_fsck: Check integrity of osl tables.
504 - Lyrics support.
505 - Reliable audio file move/rename detection.
506 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
507 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
508 Solaris (sparc64).
509 - the new osl-based audio file selector (afs) replaces the random,
510 the playlist and the mysql selector of paraslash-0.2.x.
511 - IPv6 support (thanks to Gerrit Renker).
512 - paraslash-0.2.x streams are now called "moods". Writing
513 0.3.x-mood definitions should be both easier and more
514 powerful than writing 0.2.x-stream definitions.
515 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
516 been removed. The world is a better place without them. However,
517 para_gui is still there.
518 - afs tracks audio file selection also in playlist mode.
519 - few easy-to-use afs commands replace the many not-so-easy-to-use
520 mysql commands (and are available also in playlist mode).
521 - Improved error subsystem.
522 - The earth-shaking new logo.
523
524 -----------------------------------------
525 0.2.17 (2007-11-20) "isotropic threshold"
526 -----------------------------------------
527
528 Mainly bugfixes and cleanups in this version which marks the end of
529 the 0.2.x series if no serious bugs show up after the release.
530
531 - mysql_selector: fix a locking bug.
532 - universal chunk queueing.
533 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
534 to Gerrit Renker).
535 - be more carful wrt. signed vs. unsigned argument passing.
536 - cleanup error.h and fix some references to invalid error
537 codes.
538 - update to gengetopt-2.21.
539 - update to ortp-0.13.1.
540 - autoconf: extend checks for headers, library functions and
541 compiler characteristics.
542 - Fix streaming of large mp3 files.
543 - Fix an off-by-one bug in playlist handling.
544
545 --------------------------------------
546 0.2.16 (2007-04-05) "neural discharge"
547 --------------------------------------
548
549 The main change in this release is the major audio format handler
550 cleanup which removes some similar/duplicate code and makes it easier
551 to implement plugins for other audio formats. Of course, the usual mix
552 of other improvements/changes/bugfixes also made it into the release.
553
554 - simplified audio format handlers (most of the handling functions
555 were moved one layer up to the virtual streaming system).
556 - para_server uses mmap to read audio files
557 - repositioning of mp3 streams is much faster, in particular for
558 jumping near the end of large mp3 files.
559 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
560 and AFS_WRITE.
561 - fix a bug in para_filter that caused decoding of aac files
562 to start only after a few seconds.
563 - fix osx_writer hangs
564 - simplified dccp code (thanks to Gerrit Renker)
565 - the compress filter works also on big endian systems (ppc)
566
567 -----------------------------------------
568 0.2.15 (2007-02-16) "inductive resonance"
569 -----------------------------------------
570
571 Minor improvements, more documentation and a bunch of bug fixes.
572
573 - para_server: The server.users file is only read once on server
574 startup rather than for each connection
575 - mp3dec: Fix decoding of corrupt mp3 files
576 - afs (audio file sender) is now called vss (virtual streaming
577 system). Consequently, the permission flags specified in
578 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
579 become VSS_READ and VSS_WRITE respectively.
580 - para_audiod/para_filter: Fix a bug that caused the last chunk
581 of audio data not being written under certain circumstances
582 - audiod: compute the difference of server time and local time
583 correctly
584 - para_server/para_audiod: Fix some memory leaks
585 - documentation improvements
586 - configure.ac: fix checks for para_krell
587 - new man pages
588
589 -------------------------------------------
590 0.2.14 (2006-10-15) "transient singularity"
591 -------------------------------------------
592
593 The only major enhancement of this version is the osx writer which completes
594 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
595 until now for reasons beyond the scope of this changelog entry.
596
597 - new output plugin for Mac Os: the osx writer
598 - rename configure command line options from --enable-xxx-headers to
599 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
600 - configure: new command line options: --with-mad-headers,
601 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
602 - some robustness fixes
603 - dymamic audio format recognition for audiod
604 - para_server: new command line option: --autoplay_delay
605 - para_audiod: new command line option: --clock_diff_count
606
607 ---------------------------------------
608 0.2.13 (2006-07-14) "sonic convolution"
609 ---------------------------------------
610
611 A bunch of new features and core changes.
612
613 - the new paraslash scheduler, short and sweet.
614 - Support for m4a/mp4 files via the new aac audio format
615 handler/filter (requires libfaad).
616 - each writer has its own command line parser, just like
617 para_recv and para_filter.
618 - para_client and para_audioc use the error subsystem
619 - writers are integrated in para_audiod (currently linux-only)
620 - para_client is integrated in para_audiod
621 - random/playlist selector: improved info strings
622 - new audiod commands: tasks, kill
623 - update to libortp-0.10.1
624 - para_fade: wake time defaults to 8 hours from now
625 - update to autoconf-2.60
626
627 ------------------------------------------
628 0.2.12 (2006-05-12) "oriented abstraction"
629 ------------------------------------------
630
631 Many user-visible changes in this release and lots of new
632 features:
633
634
635 - the new optional dccp sender/receiver. It uses the datagram
636 congestion control protocol. You'll need a fairly new kernel
637 for this.
638 - paraslash works on Mac OS X (thanks to Gerd Becker)
639 - para_play renamed to para_write
640 - modular output plugin design (writers) for para_write
641 - new file_writer output plugin for para_write
642 - compress filter speed improvements
643 - update to libortp-0.9.1
644 - update to gengetopt-2.17rc
645 - para_client no longer depends on libreadline (as the
646 code for the interactive mode was removed).
647 - gcc-2-95 is no longer a supported compiler. It may still
648 work, but it gets no more testing.
649 - the tarball no longer contains the screenshot images which
650 reduces its size quite a bit.
651 - configure: new command line options: --enable-mysql-headers
652 and --enable-mysql-libs
653
654 ------------------------------------
655 0.2.11 (2006-03-11) "atomic duality"
656 ------------------------------------
657
658 Here it is, the first paraslash release developed with git. There
659 are fairly many user-visible changes in this release. As two out of
660 the three "database tools" of paraslash don't use a database at all,
661 they are now called "audio file selectors" instead.
662
663
664 - the cdt command (change database tool) becomes chs (change
665 selector)
666 - no more colon separators: The syntax of some options of
667 para_audiod and para_filter have changed. Use --help for
668 more info (and some examples).
669 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
670 - switch from cvs to git (should've done that earlier)
671 - the new ipc subsystem
672 - new audio file selector: playlist
673 - para_server: the dopey selector is now called "random",
674 and is the default selector. Use the --selector option to
675 choose another selector at startup, or the chs command to
676 change the selector at runtime.
677 - X86_64 fixes (thanks to Steffen Klassert)
678 - para_play fixes
679
680 --------------------------------------
681 0.2.10 (2006-02-17) "cyclic attractor"
682 --------------------------------------
683
684 Huge documentation update, a scrollable window for para_gui, ortp
685 improvements, and of course many small fixes not mentioned here.
686 The diffstat below is rather misleading as most insertions are due
687 to the new source documentation.
688
689 - autoconf cleanup
690 - para_server also uses the new error subsystem
691 - lots of new documentation (UTSL)
692 - gui improvements:
693 - keysyms for cursor keys and for next/previous page keys
694 - scrollable output window
695 - new internal commands: scroll up/down, page up/down
696 - fix color of command output.
697 - ortp: the --chunk_time and --header flags are no longer needed
698 for para_recv/para_audiod as this information is now encoded in
699 each rtp packet sent by para_server.
700
701 -------------------------------------------
702 0.2.9 (2006-01-24) "progressive turbulence"
703 -------------------------------------------
704
705 Internal audiod receivers/filters, the new error subsystem and
706 a lot of small improvements.
707
708 - para_recv and para_filter are integrated into the para_audiod
709 binary, i.e. audiod no longer spawns a new process for
710 each receiver/filter. As para_recv and para_filter might be
711 useful as standalone programs, they still get built (linked
712 against the same object files that are also used for audiod).
713 - further ortp timing improvements should reduce the CPU usage
714 of the ortp receiver.
715 - improved audio grabbing. The 'grab' command of para_audiod
716 has its own set of command line options. Read the output of
717 "para_audioc help grab" for more info.
718 - oggdec: configurable input prebuffer size.
719 - the new error subsystem gives better error diagnostics
720 and reduces code size.
721
722 -----------------------------------------
723 0.2.8 (2006-01-02) "dynamic accumulation"
724 -----------------------------------------
725
726 The new modular filter design and the para_play-hangs bugfix.
727
728 - new executable: para_filter. It combines para_mp3dec,
729 para_oggdec and para_compress. It also adds a further filter
730 type, wav, that just inserts a wave header at the desired point
731 of the filter chain. All 'piping' is done in-memory (i.e. no
732 read/write operations are used).
733 - para_play: fix a stupid bug that caused it to hang under
734 certain circumstances.
735
736 -------------------------------------------
737 0.2.7 (2006-12-27) "transparent invariance"
738 -------------------------------------------
739
740 Not many user-visible changes but a fair amount of internal improvements.
741
742
743 - The http sender buffers data if it can not be sent
744 out immediately (because the socket is not writable). This
745 should prevent para_server from shutting down the connection
746 too early on a loaded network.
747 - para_play also prebuffers data if it is told to start at a
748 future time by the --start_time option.
749 - The return of para_recv: It combines para_ortp_recv and
750 para_http_recv. Use the --receiver option to switch between
751 the two. para_recv builds without libortp, but contains
752 only the http receiver in this case.
753 - update to ortp 0.8.1. As this ortp release contains incompatible
754 changes, para_recv-0.2.7 won't link against older ortp libs.
755 - improved ortp timings.
756 - use of gcc-extensions that #define away for non-gcc and
757 gcc < 3.0.
758
759 -------------------------------------------
760 0.2.6 (2005-10-29) "recursive compensation"
761 -------------------------------------------
762
763 Transparent session encryption (uses openssl's Alleged RC4 cipher),
764 the internal find command and several other improvements and cleanups.
765
766 - Encrypt the session if encryption is requested by the client
767 (default for para_client 0.2.6). This is backwards
768 compatible, so older clients can still connect to para_server
769 0.2.6. Use the new client option --plain to request an
770 uncrypted session (off by default, must be set to on in
771 order to connect to para_server 0.2.x with 0 <= x <= 5).
772 - para_server uses an internal function to locate audio files
773 rather than calling find(1). The server option
774 --mysql_audio_file_dir replaces --mysql_find_cmd.
775 - documentation update
776 - man pages
777 - header file cleanup
778 - para_client code cleanup
779 - para_gui: faster display of output of display commands
780
781 ------------------------------------------
782 0.2.5 (2005-10-13) "aggressive resolution"
783 ------------------------------------------
784
785 This release adds internal senders, i.e. no more external programs are
786 spawned for sending out the audio data. There are two different senders
787 available: The http sender and the ortp sender (former para_send which
788 is no longer needed).
789
790 The new sender code has a plugin-like design so it can be easily
791 extended should there be be any future need for supporting another
792 network streaming protocol. All senders are completely independent of
793 each other. In particular, the http and the ortp sender can operate
794 in parallel.
795
796 - new server command: sender to control senders at runtime.
797 Read the output of "para_server -h" and "para_client help
798 sender" for more information.
799 - para_recv renamed to para_ortp_recv
800 - new executable: para_http_recv, a simple command line
801 http receiver.
802 - major afs/mp3/ogg code simplifications due to internal
803 senders.
804 - ogg timing improvements
805 - fix several minor memory leaks (found by valgrind)
806 - empty stream definitions work again
807 - com_ne(): ignore errors on remove
808 - audiod: fix segfault on server restart
809
810 ---------------------------------------
811 0.2.4 (2005-09-21) "toxic anticipation"
812 ---------------------------------------
813
814 Several small improvements, fixes and the new grab command.
815
816 - audiod:
817 - new command: "grab" to grab the output of the stream reader
818 or any filters. Read the output of "para_audioc help grab"
819 for more information.
820 - fix memory leak
821 - code cleanup
822 - audioc: new command line option: --bufsize to specify a
823 buffer size different from the default size 8192.
824 - improved error diagnostics for para_play.
825 - new configure option: --enable-ssldir so search for openssl in
826 non-standard places
827 - sdl_gui: Make it look nice again for 1024x768
828 - server: report total size of memory allocated with sbrk by malloc,
829 new command line option: --announce_time
830
831 -----------------------------------------
832 0.2.3 (2005-09-01) "hydrophilic movement"
833 -----------------------------------------
834
835 Two new executables and major feature enhancements.
836
837 - audiod filters: It is now possible to specify arbitrary many
838 (including none) filters for each supported audio
839 format. This can be used e.g. for normalizing volume,
840 transforming or grabbing the audio stream, or for using
841 visualizers. Read the output of "para_audiod -h" for the
842 syntax of the new --filter_cmd option.
843 - new executable: para_play, a tiny alsa player. It
844 can play wave files or raw pcm (16 bit little endian)
845 from stdin.
846 - new executable: para_compress, a dynamic range compressor
847 intended to keep audio output at a consistent volume. Derived
848 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
849 - audiod: New option: --stream_delay. This can be used in
850 a local network to syncronize the audio output of all
851 clients that play the same stream.
852
853 ------------------------------------------
854 0.2.2 (2005-08-19) "tangential excitation"
855 ------------------------------------------
856
857 Mostly internal changes in this release, but also some new commands
858 for the mysql database tool.
859
860 - cleanup exec.c, fix para_exec bug
861 - compile time loglevel (log messages below the given level
862 won't be compiled in, which reduces the size of the
863 resulting binaries)
864 - new log macros that shorten the size of the source code.
865 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
866 to send only zeros. With this workaround, para_audioc works
867 again.
868 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
869 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
870 (new entry), "snp" (set numplayed). Read the manual for more
871 information.
872
873 ---------------------------------------
874 0.2.1 (2005-08-15) "surreal experience"
875 ---------------------------------------
876
877 Here comes paraslash-0.2.1. It contains a couple of new features and,
878 surprise, only minor bug fixes.
879
880 - kill noisy mp3 debug message
881 - cleanup of the build system
882 - para_server and para_client directly use the crypto routines
883 of the openssl library rather than invoking the openssl command
884 line utitlity
885 - server/audiod: new option --user to switch to the given user
886 when invoked as root. Read the output of "para_server -h" for
887 more information.
888 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
889 status. Default: "para_audioc stat"
890 - sdl_gui: new option --pic_cmd to be used to download the picture.
891 Default: "para_client pic"
892 - audiod: 5 slots ought to be enough for everybody
893 - audiod: new status item: Uptime, kill hup command
894
895 ------------------------------------------
896 0.2.0 (2005-08-06) "distributed diffusion"
897 ------------------------------------------
898
899 After several month of increased development activity, paraslash-0.2.0
900 has arrived. It contains many new features and is much more
901 self-contained than the old 0.1.x series. Enjoy!
902
903
904 - para_server: fix hang on song change and crash on sighup.
905 Speed up mysql queries. The DIR_LIKE macro is gone.
906 - new executables: para_audiod, the local audio daemon that
907 starts playback (uses SCM_CREDENTIALS socket magic) and
908 para_audioc, the corresponding client.
909 - new executables: para_mp3dec/para_oggdec, two really teensy
910 decoders. para_mp3dec is based on libmad, para_oggdec requires
911 libvorbisfile.
912 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
913 they are now called para_send and para_recv respectively.
914 - documentation updates
915 - para_gui is themable. For now there is the default theme that
916 looks as before and the simple theme: blue and easy.
917 - gui: audio streaming is now handled by audiod. Time display shows
918 playback time rather than streaming time
919 - slider: update to libzmw-0.2.0
920 - para_krell: fix crash on server shutdown
921 - switch from gzip to bzip2
922
923 ----------------------------------------
924 0.1.7 (2005-04-18) "melting penetration"
925 ----------------------------------------
926
927 The main change in this release is clearly the oggvorbis rewrite,
928 but there are also lots of smaller changes. If you intend to use both
929 the mp3 and the ogg plugin, it is recommended to use software mixing,
930 e.g. the dmix plugin which is provided by ALSA.
931
932 - new executables: para_ovsend and para_ovrecv for sending/receiving
933 oggvorbis files via rtp. Requires the open rtp library. Get it at
934 http://www.linphone.org/ortp/
935 - rewrite of the ogg_vorbis core code
936 - configure detects libzmw and, if detected, includes
937 para_slider to the list of binaries to be built by make
938 - server stream writers read from their associated fifo rather
939 than from stdin
940 - slider: two new sliders, lastplayed and numplayed
941 - fix nasty double free bug which caused random segfaults in case of
942 mp3 files with invalid header information
943 - gui: new command line option: --stream_timeout=seconds to
944 deactivate a slot if it is idle for that many seconds (default=`5')
945 - diffstats
946
947 ---------------------------------------
948 0.1.6 (2005-03-05) "asymptotic balance"
949 ---------------------------------------
950
951 Only little user-visible changes in this release. Mainly bugfixes and
952 core code cleanup. This is probably the most stable version ever if you
953 stick to mp3...
954
955 - fix several memory leaks
956 - rename default name of mysql database from "music" to "paraslash".
957 Use para_server's --mysql_database option if you do not want to
958 rename your old database.
959 - rework ogg vorbis code
960 - make update command work on mysql servers with LOCAL_INFILE
961 disabled
962 - gui: improved stream I/O (slots)
963 - simplified audio format API
964 - para_pob_ogg is gone
965
966 ------------------------------------
967 0.1.5 (2004-12-31) "opaque eternity"
968 ------------------------------------
969
970 Let's slide gently into the new year.
971
972 - new: para_slider (not built automatically, type "make
973 para_slider" to build). A toy for those who always felt that
974 creating stream definitions is difficult. See screenshots,
975 README and FEATURES for more info.
976 - improved signal handling. Fixes server segfault on SIGHUP
977 for linux kernels newer than Aug 24 2004 and makes para_gui
978 race-free.
979 - reload database tool on SIGHUP
980 - improved help message for sl
981 - do not log "broken pipe" messages as errors. They are
982 perfectly ok.
983 - fix wrong error message on permission errors
984
985 -----------------------------------------
986 0.1.4 (2004-12-19) "tunneling transition"
987 -----------------------------------------
988
989 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
990 Hopefully, most of them got wiped out with this release. Some
991 enhancements went also in.
992
993 - improved error diagnostics for all commands
994 - stradd/picadd: overwrite previous contents if entry already
995 exists, rather than returning errors
996 - stradd: use current stream if invoked without args
997 - faster (and hopefully more stable) ogg-vorbis handling
998 - para_krell: reap children to avoid zombie-flooding in case
999 no server is running
1000 - si: report also server pid
1001 - server: don't busy-loop if dbtool reports only invalid files.
1002 - gui: CTRL+C works again, fix stream_read command line option
1003 - fix pic_add, hist
1004 - fix mysql dbtool startup in case no database exists
1005 - many small fixes and cleanups
1006
1007 ---------------------------------------
1008 0.1.3: (2004-12-10) "vanishing inertia"
1009 ---------------------------------------
1010
1011 Starting from this release, the database tools are integrated in the
1012 server binary. This decreases server startup time, reduces code size
1013 and speeds up database commands. However, the layout of the underlying
1014 mysql database changed only slightly and 0.1.3 should be backwards
1015 compatible in that respect.
1016
1017 Visible changes:
1018
1019 - If mysql is not detected at compile time, or fails to init
1020 at runtime, fall back to the dopey database tool which should
1021 always work.
1022 - para_dbtool and dbtool.conf are gone. All mysql specific
1023 options are read from server.conf and are prefixed by 'mysql_'.
1024 - new command: cdt (change database tool)
1025 - new command line option: dbtool (choose startup database tool)
1026 - The name of current stream is now stored in the database,
1027 so paraslash remembers its current stream when restarted.
1028 - new command: csp (change stream and play)
1029 - para_gui also reports current database tool and server uptime
1030
1031 -------------------------------------------
1032 0.1.2: (2004-11-28) "spherical fluctuation"
1033 -------------------------------------------
1034
1035 Point release before the big dbtool changes go in.
1036
1037 - dbtool: rename ca to cam (copy all meta data). It now also
1038 copies numplayed and lastplayed time as well as the picture
1039 id.
1040 - fix endless-loop-bug caused by mp3 files with invalid header
1041
1042 -----------------------------------------
1043 0.1.1: (2004-11-05) "floating atmosphere"
1044 -----------------------------------------
1045
1046 - gkrellm plugin
1047 - new dbtool command: mbox. Browse your sound-file collection
1048 with your favorite mail reader.
1049 - several small fixes
1050
1051 -------------------------------------
1052 0.1.0: (2004-10-22) "rotating cortex"
