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

55 ----------------------------------------
56 0.5.0 (2013-08-23) "invertible validity"
57 ----------------------------------------
58
59 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
60
61 - The sideband compatibility code has been removed, hence
62 sideband connections (introduced in 0.4.11) are now mandatory.
63 - Addblob commands can produce output.
64 - The stat command no longer sends garbage when para_server was
65 compiled against libgcrypt.
66 - Dependencies for gengetopt files are computed automatically.
67 This eliminates a constant source of build bugs.
68 - The setatt command now accepts file name patterns rather than only
69 path names.
70 - overview.pdf is now based on dia, a simple diagram creation program.
71 The new version is much more detailed and contains descriptions of
72 the various programs of the paraslash package.
73 - The separator of all multi-word options has been changed from
74 underscore to dash. For example --log_color becomes --log-color.
75 - Overhauled web pages and the new logo.

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