4 -------------------------------------------------
5 0.5.3 (to be released) "symbolic synchronization"
6 -------------------------------------------------
7
8 - Various alsa-related fixes, mostly for the raspberry pi.
9 - The test suite has been extended to include sanity checks
10 for the generated man pages.
11
12 ----------------------------------------
13 0.5.2 (2014-04-11) "orthogonal interior"
14 ----------------------------------------
15
16 The new sync filter, the AES_CTR128 stream cipher and the overhauled
17 network code are the highlights of this release. It also includes a
18 fair number of smaller fixes and improvements not mentioned here.
19
20 - The new sync filter synchronizes playback between multiple
21 clients.
22 - Connections between para_server and para_client are now
23 encrypted by means of AES rather than RC4 if both sides
24 support it. RC4 is still available as a fallback. This
25 feature is fully transparent, i.e. no command line options
26 are necessary, and a client linked against openssl can
27 speak with a server linked against libgcrypt and vice versa.
28 - Major cleanup of the networking subsystem.
29 - Improvements to para_fade: the new set mode, multi-channel
30 initial volumes, better error logging.
31 - The man pages of para_audiod, para_filter, para_recv, and
32 para_write contain the relevant options for receivers, filters,
33 writers. This broke in 0.5.0.
34 - ogg/vorbis latency improvements.
35 - Improved user manual.
36 - Minor fixes to avoid clang warnings.

42 0.5.1 (2013-12-20) "temporary implication"
43 ------------------------------------------
44
45 Lots of fixes and improvements all over the place, and a major overhaul
46 of the build system.
47
48 - Audiod improvements and fixes.
49 - Buffer tree robustness improvements.
50 - Cleanup of the mood subsystem.
51 - Fixes and cleanups for the flac decoder.
52 - Latency improvements for the ogg/opus decoder.
53 - Crypto support is now optional. On systems without
54 openssl/gcrypt, the build succeeds but para_server,
55 para_audiod, para_client won't be built.
56 - The build system now works for cross-compile setups.
57 - The dependency tree has been flattened, which speeds up
58 builds and avoids to recreate the man pages on every change.
59 - The error code helper has been rewritten from perl to C,
60 which further improves build time.
61 - Many small bugs in the build system have been identified
62 and fixed.

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

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