17 ----------------------------------------
18
19 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
20
21 - The sideband compatibility code has been removed, hence
22 sideband connections (introduced in 0.4.11) are now mandatory.
23 - Addblob commands can produce output.
24 - The stat command no longer sends garbage when para_server was
25 compiled against libgcrypt.

27 This eliminates a constant source of build bugs.
28 - The setatt command now accepts file name patterns rather than only
29 path names.
30 - overview.pdf is now based on dia, a simple diagram creation program.
31 The new version is much more detailed and contains descriptions of
32 the various programs of the paraslash package.
33 - The separator of all multi-word options has been changed from
34 underscore to dash. For example --log_color becomes --log-color.
35 - Overhauled web pages and the new logo.

40 --------------------------------------
41 0.4.13 (2013-07-29) "spectral gravity"
42 --------------------------------------
43
44 One more 0.4.x release before the API-breaking changes for 0.5.0 go
45 in. The main features of this release are the ogg/opus audio format,
46 and UTF-8 support, but it includes also tons of other improvements
47 and fixes all over the place.
48
49 - New audio format: ogg/opus.
50 - UTF8 support for para_gui and the mp3 audio format handler.
51 - Scheduler improvements and fixes.
52 - The obsolete gettimeofday() function has been replaced
53 by clock_gettime() on systems which support it.
54 - Speed and usability improvements for para_gui.
55 - para_client now restores the fd flags of stdin and stdout
56 on shutdown.
57 - Improved manual pages.
58 - Consistent version strings for all executables.
59 - Reduced dependencies on generated files result in fewer
60 recompilations on changes.
61 - Performance improvements for the compress filter.
62 - Improved downloads web page.
63
64 -----------------------------------------
65 0.4.12 (2012-12-20) "volatile relativity"
66 -----------------------------------------
67 The new command line player, the resample filter, ALSA support for
68 para_fade, and the improved build system are the highlights of this
69 release which probably marks the end of the 0.4.x series.
70
71 - The afh receiver and the para_play executable.
72 - The resample filter: A sample rate converter based on
73 libsamplerate.
74 - The "versions" directory has been removed from the master
75 branch. The tarballs of the old releases are now available
76 in the new "releases" branch.
77 - Overhaul of the build system: All generated files are now
78 written to the "build" directory.
79 - The modular mixer API and the alsa mixer.
80 - Minor fixes for the osx writer.
81
82 --------------------------------------
83 0.4.11 (2012-07-20) "mutual diversity"
84 --------------------------------------
85
86 The major feature in this release is the new sideband API for
87 client-server communication. This API will be used exclusively starting
88 with 0.5.0, which breaks backward compatibility but allows to get rid
89 of quite some compatibility code. Other noteworthy changes include
90 decoder latency improvements and a long-standing bug fix for the
91 ALSA writer.
92
93 - Sideband connections: If both para_server and para_client
94 support this feature, data is sent as a multiplexed stream.
95 - The --no_default_filters option of para_filter has been
96 removed.
97 - Several fixes and latency improvements to various decoders.
98 - The ALSA writer now limits the prebuffer time to 500ms.
99 - Documentation improvements.
100 - Overhaul of the command_util.sh script.
101 - Fixes for some minor problems found by the clang analyzer.
102 - Compiles (almost) without warnings on gcc-3.
103 - Robustness improvements of the buffer tree code.
104
105 ------------------------------------------
106 0.4.10 (2012-03-30) "heterogeneous vacuum"
107 ------------------------------------------
108
109 Nothing earth-shaking in this release, but quite a few usability
110 improvements and the usual mix of cleanups and fixes.
111
112 - The --no_default_filters option of para_filter has been
113 deprecated. It still works but has no effect and will be
114 removed in the next version.
115 - para_gui now prints also the stderr output of the executing
116 command in the bottom window.
117 - Cleanup and consolidation of the various wrappers for
118 write(), writev(), send() and friends.
119 - The obscure error messages on mmap() failures have been
120 replaced by meaningful messages. This affects mainly
121 para_afh.
122 - para_audioc: Cleanups and memory leak fixes.
123 - Test 0004-server no longer fails if para_server is not
124 being built.
125 - New configure options: --with-id3tag-{headers,libs}.
126
127 -------------------------------------
128 0.4.9 (2011-12-06) "hybrid causality"
129 -------------------------------------
130
131 Support for another audio format, interactive mode for para_client
132 and para_audiod and many small improvements/fixes all over the place.
133
134 - Support for flac, the free lossless audio codec.
135 - Fix for an endless loop in the mp3 decoder for certain
136 (corrupt) mp3 files.
137 - When executed without specifying a command, para_client
138 and para_audioc start an interactive shell (requires
139 libreadline being installed). The interactive mode offers
140 full tab completion and command line history.
141 - autogen.sh now detects a distcc setup and adjusts the
142 parameter for the -j option of make accordingly.
143 - Shared memory areas are no longer restricted to 64K. We now
144 detect the maximal size of a shared memory area at runtime.
145 - cleanup of the internal uptime API.
146 - para_server prefaults the mmapped audio file to avoid
147 delays on slow media.
148 - A new test for the test-suite that exercises the
149 communication between para_server and para_audiod.
150 - The alsa writer eats up less CPU cycles when configured to
151 use the DMIX plugin.
152 - Simplified and unified receiver code.
153 - Makefile cleanups.
154 - Commands which print a list of matching audio files now
155 emit a meaningful error message if no audio file matched the
156 given pattern(s).
157
158 --------------------------------------
159 0.4.8 (2011-08-19) "nested assignment"
160 --------------------------------------
161
162 Gcrypt support, the overhauled osx writer and regex format specifiers
163 are the highlights of this release.
164
165 - support for libgcrypt as a drop-in replacement for openssl.
166 Run configure --enable-cryptolib=gcrypt to link against
167 libgcrypt. The two crypto implementations are compatible to
168 each other, i.e. a para_client executable linked against
169 gcrypt can connect to para_server linked against libssl
170 and vice versa.
171 - Rewrite of the osx writer (output plugin for Mac OS).
172 - audiod: The format specifier for receivers, filters and
173 writers is now treated as a regular expression. This allows
174 to replace 5 lines in the config file (one for each audio
175 format) by one single line. See the manual for details.
176 - The *.cmdline.[ch] files are no longer contained in the released
177 tarballs. This reduces the size of the tarballs but requires
178 gengetopt to build the tarball.
179 - Compiles cleanly also with llvm/clang.
180 - Corrupt mp3 files are handled more gracefully.
181 - The alsa writer uses poll fds instead of computing timeouts.
182 - Cleanup of the generic writer API.
183 - sched: Optimized zero timeouts.
184 - vss timeout cleanups.
185 - oggdec fixes and improvements.
186
187 --------------------------------------
188 0.4.7 (2011-06-01) "infinite rollback"
189 --------------------------------------
190
191 The new ao writer, support for ssh RSA keys and a couple of other
192 enhancements.
193
194 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
195 platforms through the libao audio library.
196 - Support for RSA keys generated with ssh-keygen.
197 - configure: improved options for ogg/vorbis/speex.
198 - The git version reported by --version always matches HEAD.
199 - The autogen script detects the number of processors and
200 runs a parallel make if possible.
201 - Major cleanup of the crypto API.
202 - Documentation updates.
203
204 ------------------------------------------
205 0.4.6 (2011-03-31) "deterministic entropy"
206 ------------------------------------------
207
208 Lots of ogg/vorbis improvements, the new test suite, enhancements
209 for para_gui and a fair amount of other bug fixes.
210
211 - For DCCP/OGG streams the audio file header is only sent once
212 at the beginning of the stream rather than periodically
213 every five seconds. This reduces network traffic and the
214 FEC group size.
215 - The vorbis comment header is replaced by an empty dummy header
216 before the header is sent over the network. This also results in
217 less network traffic and smaller FEC groups.
218 - The new "test" make target allows to perform some sanity checks prior
219 to installing the package.
220 - ogg timing fixes and performance improvements
221 - Scheduler improvements
222 - Proper exit codes for para_write
223 - para_gui: New option --theme to select a startup theme. Several
224 other improvements and fixes.
225 - aacdec error message cleanups
226 - simplified color error handling
227
228 --------------------------------------------
229 0.4.5 (2010-12-17) "symmetric randomization"
230 --------------------------------------------
231
232 Bug fixes, internal cleanups and variable-sized FEC slices.
233
234 - Contains a fix for an invalid-free-bug in the ogg audio format
235 handler code.
236 - Switching off the DCCP sender works again.
237 - para_audiod handles crashes of para_server more robustly.
238 - Internal scheduler and writer cleanups.
239 - Reduced latency due to variable-sized FEC slices.
240 - Improved documentation and error diagnostics.
241 - The build of para_server is now optional, allowing the build
242 to succeed in case libosl is not installed.
243
244 ------------------------------------------
245 0.4.4 (2010-08-06) "persistent regularity"
246 ------------------------------------------
247
248 Support for yet another audio format, para_write improvements and
249 bug fixes.
250
251 - Support for the speex codec.
252 - Support for sample formats other than 16 bit little endian.
253 - error2.h is now created by a perl script which speeds up configure
254 considerably.
255 - Fix a bug in the aac decoder which could lead to segfaults in
256 para_filter/para_audiod.
257 - Fixes for autoconf-2.66.
258
259 ----------------------------------------
260 0.4.3 (2010-07-05) "imaginary radiation"
261 ----------------------------------------
262
263 Many improvements for the DCCP and the UDP transport, the new user
264 manual and the usual mix of bug fixes and internal improvements.
265
266 - FEC support for the DCCP sender (Gerrit Renker). The new
267 --dccp_max_slice_size, --dccp_data_slices_per_group and
268 --dccp_slices_per_group options can be used to set the FEC
269 parameters for the DCCP transport.
270 - DNS lookups for UDP targets (Gerrit Renker).
271 - The new user manual replaces the README, README.afs, REQUIREMENTS
272 and INSTALL documents.
273 - Fix an end-of-file detection bug in the oggdec filter.
274 - The new nonblock API.
275 - Both options of the oggdec filter have been removed.
276 - New debug mode for the internal scheduler.
277
278 ------------------------------------------
279 0.4.2 (2010-04-23) "associative expansion"
280 ------------------------------------------
281
282 It's been some time since the last release, but finally here is
283 paraslash-0.4.2. The bulk of the changes comes from the new buffer
284 tree API, but there are changes all over the tree. Mainly performance
285 and usability improvements, but also quite some bug fixes.
286
287 - The new buffer tree API.
288 - DCCP: Support for CCID negotiation (Gerrit Renker).
289 - UDP robustness fixes.
290 - The --bufsize option for mp3dec is gone as it no longer makes sense
291 for the new buffer tree API.
292 - Fix audible buffer underruns for wma streams.
293 - The alsa writer no longer prints meaningless underrun durations.
294 - audiod: Defaults work also for udp streams. If no filter is
295 given for an audio format that is received via upd, fecdec is
296 automatically added as the first filter (along with the decoder).
297
298 ---------------------------------------
299 0.4.1 (2009-12-22) "concurrent horizon"
300 ---------------------------------------
301
302 Support for another audio format, minor feature enhancements and lots of bug
303 fixes. All fixes that have been accumulated in the maint branch (in particular
304 those mentionened in the 0.3.6 release notes) appear in this release as well.
305
306 - wma support.
307 - new afh option: --human to activate human-readable output.
308 - new server/audiod option: --log-timing to print timing information.
309 - build system improvements.
310 - source code documentation updates.
311
312 -------------------------------------
313 0.3.6 (2009-12-07) "cubic continuity"
314 -------------------------------------
315
316 Quite a few bugs have been found and fixed since 0.3.5, so here's
317 another 0.3.x release. No new features.
318
319 - Always check return value of malloc().
320 - ogg vorbis/FEC: Do not write garbage after the audio file header.
321 - exit if root privileges could not be dropped.
322 - FEC: Fix computation of extra slices.
323 - oss: Fix check for empty input buffer.
324 - Avoid buffer underruns due to filter chain output buffer constraints.
325 - server: Fix assignment of afs_pid.
326 - Don't panic if the afs database contains unknown audio formats.
327 - http/dccp: Do not send the audio file header twice.
328 - FEC: Timing improvements.
329
330 ----------------------------------------------
331 0.4.0 (2009-11-10) "simultaneous independence"
332 ----------------------------------------------
333
334 Two significant changes which require the new version number: The
335 improved authentication dialog and the fact that the database code
336 has been moved to a library, libosl. To use the new version, you have
337 to generate new RSA keys, see INSTALL for details. A shell script is
338 provided for conversion of the 0.3 database to the new 0.4 format.
339
340 - stronger crypto for client authentication
341 - the database code has been moved to a library
342 - improved status item handling
343 - cleanup of the build system
344 - The "-V" option now also prints the git version
345 - the new parser-friendly listing mode for the ls and stat commands
346 - mandatory rc4 encryption
347 - major audio format handler cleanups
348 - (id3,...) tags are no longer stored as a combined string in the database
349 - new mood methods: artist_matches, title_matches, comment_matches,
350 album_matches, year_maches, year.
351
352 --------------------------------------------
353 0.3.5 (2009-09-21) "symplectic separability"
354 --------------------------------------------
355
356 Full client support for *BSD Unixes, complete re-write of the ogg
357 vorbis audio format handler, various improvements all over the place
358 and the usual mix of bugfixes. This release marks the end of the 0.3
359 series if no serious problems show up.
360
361 - the new oss writer (supported on *BSD and Linux)
362 - rewrite of the ogg vorbis audio format handler. It's
363 recommended to replace the chunk tables of existing ogg
364 vorbis files in the afs database by re-adding these files
365 with "add -f".
366 - support for netmask subsets (Gerrit Renker)
367 - the new prebuffer filter
368 - improved signal handling
369 - variable fec output buffer size
370 - improved FEC timing fixes audible buffer underruns in UDP mode
371 - --log_color actually works
372 - new ls option: -d (print dates as seconds after the epoch)
373 - update to gengetopt 2.22.2
374 - support for RSA keys of size > 512 bits
375 - new option "mixer_channel" for para_fade
376
377 -----------------------------------------
378 0.3.4 (2009-05-07) "elliptic inheritance"
379 -----------------------------------------
380
381 The new udp sender, forward error correction, colored logs and various
382 other improvements. As the udp sender does not depend on any special
383 libraries, it is built unconditionally.
384
385 - The udp sender replaces the ortp sender. The new code uses forward
386 error correction to protect against packet losses. Many thanks to
387 Gerrit Renker for providing ipv6 support.
388 - The default port for udp streaming now defaults to 8000, like
389 for the http and the dccp senders/receivers.
390 - Loglevels are now specified as symbolic names, e.g.
391 "--loglevel info".
392 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
393 - para_server/para_audiod: Color support for log messages.
394 - new options for mp3dec: --ignore-crc, --bufsize
395 - new audiod option: --config-file.
396 - gengetopt cleanups.
397 - Improved help/man pages: The documentation of para_audiod,
398 para_recv, para_filter and para_write now also contains
399 all options of the available receivers/filters/writers. The
400 man page of para_fade contains a description of the different
401 modes of operation.
402 - More source code documentation.
403 - vss timing fixes.
404
405 --------------------------------------------
406 0.3.3 (2008-12-01) "axiomatic perspectivity"
407 --------------------------------------------
408
409 Internal code cleanups, bug fixes, improved tag handling and the new
410 amplification filter.
411
412 - para_server uses the generic scheduling code.
413 - overhaul of the virtual streaming system.
414 - mp3: id3 version 2 support via libid3tag (optional)
415 - ogg: vorbis comment support.
416 - aac meta info support.
417 - mp3 audio format handler cleanups.
418 - new filter: "amp" to amplify the amplitude of the audio stream
419 - new status item/database entry: amplification. It is
420 used by the amp filter to pre-amplify the audio stream.
421 - fix a close-without-open bug in para_write.
422 - fix a bug in com_init() which was introduced in 0.3.2.
423 - better error diagnostics for para_client.
424
425 -----------------------------------------
426 0.3.2 (2008-04-11) "probabilistic parity"
427 -----------------------------------------
428
429 The new para_afh executable, scheduling and documentation improvements.
430
431 - new ls option: -lc (list chunk table)
432 - new executable: para_afh, the stand-alone audio file handler tool
433 - afs commands can send output more than SHMMAX (32MB on Linux). This
434 also reduces the memory usage of commands that produce large amounts
435 of output.
436 - major scheduler and audiod cleanups.
437 - more detailed and much nicer man pages.
438
439 ---------------------------------------
440 0.3.1 (2008-02-23) "liquid interaction"
441 ---------------------------------------
442
443 A mix of cleanups, bug fixes, improvements, and some new features. No
444 significant changes to the new database (osl) code, which is generally
445 a good sign.
446
447 - Share some similar/duplicate code between the http and the
448 dccp sender.
449 - Generic access control lists for paraslash senders.
450 - dccp sender: Access control lists, connection limiting and support
451 for the allow,deny,on,off,help sender commands.
452 - The default dccp port changed from 5001 to 8000 (suggested by
453 Gerrit Renker).
454 - para_server starts even if not all public keys could be loaded.
455 - Audiod performance improvements.
456 - fix a bug in the "off" command of the http sender.
457 - fix some fd and memory leaks.
458 - Update to gengetopt-2.22.
459
460 -------------------------------------
461 0.3.0 (2008-01-12) "solar saturation"
462 -------------------------------------
463
464 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
465
466
467 Usually one might expect lots of new features AND a big increase in size
468 for a major release like this.
469
470 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
471 ever. The decrease in size is mostly due to the removal of some
472 graphical tools (which were only quick hacks anyway). But also the
473 fact that the mysql code is gone cuts down the size a bit.
474
475 Being independent of mysql comes at a cost: The fact that paraslash
476 now contains its own database (the object storage layer, osl) increases
477 the (stripped) binary size of para_server by ~50K on i386.
478
479 - no more restrictions on unique basenames.
480 - independent of mysql: The new self-contained object
481 storage layer (osl) replaces the mysql database.
482 - New executable para_fsck: Check integrity of osl tables.
483 - Lyrics support.
484 - Reliable audio file move/rename detection.
485 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
486 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
487 Solaris (sparc64).
488 - the new osl-based audio file selector (afs) replaces the random,
489 the playlist and the mysql selector of paraslash-0.2.x.
490 - IPv6 support (thanks to Gerrit Renker).
491 - paraslash-0.2.x streams are now called "moods". Writing
492 0.3.x-mood definitions should be both easier and more
493 powerful than writing 0.2.x-stream definitions.
494 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
495 been removed. The world is a better place without them. However,
496 para_gui is still there.
497 - afs tracks audio file selection also in playlist mode.
498 - few easy-to-use afs commands replace the many not-so-easy-to-use
499 mysql commands (and are available also in playlist mode).
500 - Improved error subsystem.
501 - The earth-shaking new logo.
502
503 -----------------------------------------
504 0.2.17 (2007-11-20) "isotropic threshold"
505 -----------------------------------------
506
507 Mainly bugfixes and cleanups in this version which marks the end of
508 the 0.2.x series if no serious bugs show up after the release.
509
510 - mysql_selector: fix a locking bug.
511 - universal chunk queueing.
512 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
513 to Gerrit Renker).
514 - be more carful wrt. signed vs. unsigned argument passing.
515 - cleanup error.h and fix some references to invalid error
516 codes.
517 - update to gengetopt-2.21.
518 - update to ortp-0.13.1.
519 - autoconf: extend checks for headers, library functions and
520 compiler characteristics.
521 - Fix streaming of large mp3 files.
522 - Fix an off-by-one bug in playlist handling.
523
524 --------------------------------------
525 0.2.16 (2007-04-05) "neural discharge"
526 --------------------------------------
527
528 The main change in this release is the major audio format handler
529 cleanup which removes some similar/duplicate code and makes it easier
530 to implement plugins for other audio formats. Of course, the usual mix
531 of other improvements/changes/bugfixes also made it into the release.
532
533 - simplified audio format handlers (most of the handling functions
534 were moved one layer up to the virtual streaming system).
535 - para_server uses mmap to read audio files
536 - repositioning of mp3 streams is much faster, in particular for
537 jumping near the end of large mp3 files.
538 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
539 and AFS_WRITE.
540 - fix a bug in para_filter that caused decoding of aac files
541 to start only after a few seconds.
542 - fix osx_writer hangs
543 - simplified dccp code (thanks to Gerrit Renker)
544 - the compress filter works also on big endian systems (ppc)
545
546 -----------------------------------------
547 0.2.15 (2007-02-16) "inductive resonance"
548 -----------------------------------------
549
550 Minor improvements, more documentation and a bunch of bug fixes.
551
552 - para_server: The server.users file is only read once on server
553 startup rather than for each connection
554 - mp3dec: Fix decoding of corrupt mp3 files
555 - afs (audio file sender) is now called vss (virtual streaming
556 system). Consequently, the permission flags specified in
557 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
558 become VSS_READ and VSS_WRITE respectively.
559 - para_audiod/para_filter: Fix a bug that caused the last chunk
560 of audio data not being written under certain circumstances
561 - audiod: compute the difference of server time and local time
562 correctly
563 - para_server/para_audiod: Fix some memory leaks
564 - documentation improvements
565 - configure.ac: fix checks for para_krell
566 - new man pages
567
568 -------------------------------------------
569 0.2.14 (2006-10-15) "transient singularity"
570 -------------------------------------------
571
572 The only major enhancement of this version is the osx writer which completes
573 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
574 until now for reasons beyond the scope of this changelog entry.
575
576 - new output plugin for Mac Os: the osx writer
577 - rename configure command line options from --enable-xxx-headers to
578 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
579 - configure: new command line options: --with-mad-headers,
580 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
581 - some robustness fixes
582 - dymamic audio format recognition for audiod
583 - para_server: new command line option: --autoplay_delay
584 - para_audiod: new command line option: --clock_diff_count
585
586 ---------------------------------------
587 0.2.13 (2006-07-14) "sonic convolution"
588 ---------------------------------------
589
590 A bunch of new features and core changes.
591
592 - the new paraslash scheduler, short and sweet.
593 - Support for m4a/mp4 files via the new aac audio format
594 handler/filter (requires libfaad).
595 - each writer has its own command line parser, just like
596 para_recv and para_filter.
597 - para_client and para_audioc use the error subsystem
598 - writers are integrated in para_audiod (currently linux-only)
599 - para_client is integrated in para_audiod
600 - random/playlist selector: improved info strings
601 - new audiod commands: tasks, kill
602 - update to libortp-0.10.1
603 - para_fade: wake time defaults to 8 hours from now
604 - update to autoconf-2.60
605
606 ------------------------------------------
607 0.2.12 (2006-05-12) "oriented abstraction"
608 ------------------------------------------
609
610 Many user-visible changes in this release and lots of new
611 features:
612
613
614 - the new optional dccp sender/receiver. It uses the datagram
615 congestion control protocol. You'll need a fairly new kernel
616 for this.
617 - paraslash works on Mac OS X (thanks to Gerd Becker)
618 - para_play renamed to para_write
619 - modular output plugin design (writers) for para_write
620 - new file_writer output plugin for para_write
621 - compress filter speed improvements
622 - update to libortp-0.9.1
623 - update to gengetopt-2.17rc
624 - para_client no longer depends on libreadline (as the
625 code for the interactive mode was removed).
626 - gcc-2-95 is no longer a supported compiler. It may still
627 work, but it gets no more testing.
628 - the tarball no longer contains the screenshot images which
629 reduces its size quite a bit.
630 - configure: new command line options: --enable-mysql-headers
631 and --enable-mysql-libs
632
633 ------------------------------------
634 0.2.11 (2006-03-11) "atomic duality"
635 ------------------------------------
636
637 Here it is, the first paraslash release developed with git. There
638 are fairly many user-visible changes in this release. As two out of
639 the three "database tools" of paraslash don't use a database at all,
640 they are now called "audio file selectors" instead.
641
642
643 - the cdt command (change database tool) becomes chs (change
644 selector)
645 - no more colon separators: The syntax of some options of
646 para_audiod and para_filter have changed. Use --help for
647 more info (and some examples).
648 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
649 - switch from cvs to git (should've done that earlier)
650 - the new ipc subsystem
651 - new audio file selector: playlist
652 - para_server: the dopey selector is now called "random",
653 and is the default selector. Use the --selector option to
654 choose another selector at startup, or the chs command to
655 change the selector at runtime.
656 - X86_64 fixes (thanks to Steffen Klassert)
657 - para_play fixes
658
659 --------------------------------------
660 0.2.10 (2006-02-17) "cyclic attractor"
661 --------------------------------------
662
663 Huge documentation update, a scrollable window for para_gui, ortp
664 improvements, and of course many small fixes not mentioned here.
665 The diffstat below is rather misleading as most insertions are due
666 to the new source documentation.
667
668 - autoconf cleanup
669 - para_server also uses the new error subsystem
670 - lots of new documentation (UTSL)
671 - gui improvements:
672 - keysyms for cursor keys and for next/previous page keys
673 - scrollable output window
674 - new internal commands: scroll up/down, page up/down
675 - fix color of command output.
676 - ortp: the --chunk_time and --header flags are no longer needed
677 for para_recv/para_audiod as this information is now encoded in
678 each rtp packet sent by para_server.
679
680 -------------------------------------------
681 0.2.9 (2006-01-24) "progressive turbulence"
682 -------------------------------------------
683
684 Internal audiod receivers/filters, the new error subsystem and
685 a lot of small improvements.
686
687 - para_recv and para_filter are integrated into the para_audiod
688 binary, i.e. audiod no longer spawns a new process for
689 each receiver/filter. As para_recv and para_filter might be
690 useful as standalone programs, they still get built (linked
691 against the same object files that are also used for audiod).
692 - further ortp timing improvements should reduce the CPU usage
693 of the ortp receiver.
694 - improved audio grabbing. The 'grab' command of para_audiod
695 has its own set of command line options. Read the output of
696 "para_audioc help grab" for more info.
697 - oggdec: configurable input prebuffer size.
698 - the new error subsystem gives better error diagnostics
699 and reduces code size.
700
701 -----------------------------------------
702 0.2.8 (2006-01-02) "dynamic accumulation"
703 -----------------------------------------
704
705 The new modular filter design and the para_play-hangs bugfix.
706
707 - new executable: para_filter. It combines para_mp3dec,
708 para_oggdec and para_compress. It also adds a further filter
709 type, wav, that just inserts a wave header at the desired point
710 of the filter chain. All 'piping' is done in-memory (i.e. no
711 read/write operations are used).
712 - para_play: fix a stupid bug that caused it to hang under
713 certain circumstances.
714
715 -------------------------------------------
716 0.2.7 (2006-12-27) "transparent invariance"
717 -------------------------------------------
718
719 Not many user-visible changes but a fair amount of internal improvements.
720
721
722 - The http sender buffers data if it can not be sent
723 out immediately (because the socket is not writable). This
724 should prevent para_server from shutting down the connection
725 too early on a loaded network.
726 - para_play also prebuffers data if it is told to start at a
727 future time by the --start_time option.
728 - The return of para_recv: It combines para_ortp_recv and
729 para_http_recv. Use the --receiver option to switch between
730 the two. para_recv builds without libortp, but contains
731 only the http receiver in this case.
732 - update to ortp 0.8.1. As this ortp release contains incompatible
733 changes, para_recv-0.2.7 won't link against older ortp libs.
734 - improved ortp timings.
735 - use of gcc-extensions that #define away for non-gcc and
736 gcc < 3.0.
737
738 -------------------------------------------
739 0.2.6 (2005-10-29) "recursive compensation"
740 -------------------------------------------
741
742 Transparent session encryption (uses openssl's Alleged RC4 cipher),
743 the internal find command and several other improvements and cleanups.
744
745 - Encrypt the session if encryption is requested by the client
746 (default for para_client 0.2.6). This is backwards
747 compatible, so older clients can still connect to para_server
748 0.2.6. Use the new client option --plain to request an
749 uncrypted session (off by default, must be set to on in
750 order to connect to para_server 0.2.x with 0 <= x <= 5).
751 - para_server uses an internal function to locate audio files
752 rather than calling find(1). The server option
753 --mysql_audio_file_dir replaces --mysql_find_cmd.
754 - documentation update
755 - man pages
756 - header file cleanup
757 - para_client code cleanup
758 - para_gui: faster display of output of display commands
759
760 ------------------------------------------
761 0.2.5 (2005-10-13) "aggressive resolution"
762 ------------------------------------------
763
764 This release adds internal senders, i.e. no more external programs are
765 spawned for sending out the audio data. There are two different senders
766 available: The http sender and the ortp sender (former para_send which
767 is no longer needed).
768
769 The new sender code has a plugin-like design so it can be easily
770 extended should there be be any future need for supporting another
771 network streaming protocol. All senders are completely independent of
772 each other. In particular, the http and the ortp sender can operate
773 in parallel.
774
775 - new server command: sender to control senders at runtime.
776 Read the output of "para_server -h" and "para_client help
777 sender" for more information.
778 - para_recv renamed to para_ortp_recv
779 - new executable: para_http_recv, a simple command line
780 http receiver.
781 - major afs/mp3/ogg code simplifications due to internal
782 senders.
783 - ogg timing improvements
784 - fix several minor memory leaks (found by valgrind)
785 - empty stream definitions work again
786 - com_ne(): ignore errors on remove
787 - audiod: fix segfault on server restart
788
789 ---------------------------------------
790 0.2.4 (2005-09-21) "toxic anticipation"
791 ---------------------------------------
792
793 Several small improvements, fixes and the new grab command.
794
795 - audiod:
796 - new command: "grab" to grab the output of the stream reader
797 or any filters. Read the output of "para_audioc help grab"
798 for more information.
799 - fix memory leak
800 - code cleanup
801 - audioc: new command line option: --bufsize to specify a
802 buffer size different from the default size 8192.
803 - improved error diagnostics for para_play.
804 - new configure option: --enable-ssldir so search for openssl in
805 non-standard places
806 - sdl_gui: Make it look nice again for 1024x768
807 - server: report total size of memory allocated with sbrk by malloc,
808 new command line option: --announce_time
809
810 -----------------------------------------
811 0.2.3 (2005-09-01) "hydrophilic movement"
812 -----------------------------------------
813
814 Two new executables and major feature enhancements.
815
816 - audiod filters: It is now possible to specify arbitrary many
817 (including none) filters for each supported audio
818 format. This can be used e.g. for normalizing volume,
819 transforming or grabbing the audio stream, or for using
820 visualizers. Read the output of "para_audiod -h" for the
821 syntax of the new --filter_cmd option.
822 - new executable: para_play, a tiny alsa player. It
823 can play wave files or raw pcm (16 bit little endian)
824 from stdin.
825 - new executable: para_compress, a dynamic range compressor
826 intended to keep audio output at a consistent volume. Derived
827 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
828 - audiod: New option: --stream_delay. This can be used in
829 a local network to syncronize the audio output of all
830 clients that play the same stream.
831
832 ------------------------------------------
833 0.2.2 (2005-08-19) "tangential excitation"
834 ------------------------------------------
835
836 Mostly internal changes in this release, but also some new commands
837 for the mysql database tool.
838
839 - cleanup exec.c, fix para_exec bug
840 - compile time loglevel (log messages below the given level
841 won't be compiled in, which reduces the size of the
842 resulting binaries)
843 - new log macros that shorten the size of the source code.
844 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
845 to send only zeros. With this workaround, para_audioc works
846 again.
847 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
848 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
849 (new entry), "snp" (set numplayed). Read the manual for more
850 information.
851
852 ---------------------------------------
853 0.2.1 (2005-08-15) "surreal experience"
854 ---------------------------------------
855
856 Here comes paraslash-0.2.1. It contains a couple of new features and,
857 surprise, only minor bug fixes.
858
859 - kill noisy mp3 debug message
860 - cleanup of the build system
861 - para_server and para_client directly use the crypto routines
862 of the openssl library rather than invoking the openssl command
863 line utitlity
864 - server/audiod: new option --user to switch to the given user
865 when invoked as root. Read the output of "para_server -h" for
866 more information.
867 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
868 status. Default: "para_audioc stat"
869 - sdl_gui: new option --pic_cmd to be used to download the picture.
870 Default: "para_client pic"
871 - audiod: 5 slots ought to be enough for everybody
872 - audiod: new status item: Uptime, kill hup command
873
874 ------------------------------------------
875 0.2.0 (2005-08-06) "distributed diffusion"
876 ------------------------------------------
877
878 After several month of increased development activity, paraslash-0.2.0
879 has arrived. It contains many new features and is much more
880 self-contained than the old 0.1.x series. Enjoy!
881
882
883 - para_server: fix hang on song change and crash on sighup.
884 Speed up mysql queries. The DIR_LIKE macro is gone.
885 - new executables: para_audiod, the local audio daemon that
886 starts playback (uses SCM_CREDENTIALS socket magic) and
887 para_audioc, the corresponding client.
888 - new executables: para_mp3dec/para_oggdec, two really teensy
889 decoders. para_mp3dec is based on libmad, para_oggdec requires
890 libvorbisfile.
891 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
892 they are now called para_send and para_recv respectively.
893 - documentation updates
894 - para_gui is themable. For now there is the default theme that
895 looks as before and the simple theme: blue and easy.
896 - gui: audio streaming is now handled by audiod. Time display shows
897 playback time rather than streaming time
898 - slider: update to libzmw-0.2.0
899 - para_krell: fix crash on server shutdown
900 - switch from gzip to bzip2
901
902 ----------------------------------------
903 0.1.7 (2005-04-18) "melting penetration"
904 ----------------------------------------
905
906 The main change in this release is clearly the oggvorbis rewrite,
907 but there are also lots of smaller changes. If you intend to use both
908 the mp3 and the ogg plugin, it is recommended to use software mixing,
909 e.g. the dmix plugin which is provided by ALSA.
910
911 - new executables: para_ovsend and para_ovrecv for sending/receiving
912 oggvorbis files via rtp. Requires the open rtp library. Get it at
913 http://www.linphone.org/ortp/
914 - rewrite of the ogg_vorbis core code
915 - configure detects libzmw and, if detected, includes
916 para_slider to the list of binaries to be built by make
917 - server stream writers read from their associated fifo rather
918 than from stdin
919 - slider: two new sliders, lastplayed and numplayed
920 - fix nasty double free bug which caused random segfaults in case of
921 mp3 files with invalid header information
922 - gui: new command line option: --stream_timeout=seconds to
923 deactivate a slot if it is idle for that many seconds (default=`5')
924 - diffstats
925
926 ---------------------------------------
927 0.1.6 (2005-03-05) "asymptotic balance"
928 ---------------------------------------
929
930 Only little user-visible changes in this release. Mainly bugfixes and
931 core code cleanup. This is probably the most stable version ever if you
932 stick to mp3...
933
934 - fix several memory leaks
935 - rename default name of mysql database from "music" to "paraslash".
936 Use para_server's --mysql_database option if you do not want to
937 rename your old database.
938 - rework ogg vorbis code
939 - make update command work on mysql servers with LOCAL_INFILE
940 disabled
941 - gui: improved stream I/O (slots)
942 - simplified audio format API
943 - para_pob_ogg is gone
944
945 ------------------------------------
946 0.1.5 (2004-12-31) "opaque eternity"
947 ------------------------------------
948
949 Let's slide gently into the new year.
950
951 - new: para_slider (not built automatically, type "make
952 para_slider" to build). A toy for those who always felt that
953 creating stream definitions is difficult. See screenshots,
954 README and FEATURES for more info.
955 - improved signal handling. Fixes server segfault on SIGHUP
956 for linux kernels newer than Aug 24 2004 and makes para_gui
957 race-free.
958 - reload database tool on SIGHUP
959 - improved help message for sl
960 - do not log "broken pipe" messages as errors. They are
961 perfectly ok.
962 - fix wrong error message on permission errors
963
964 -----------------------------------------
965 0.1.4 (2004-12-19) "tunneling transition"
966 -----------------------------------------
967
968 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
969 Hopefully, most of them got wiped out with this release. Some
970 enhancements went also in.
971
972 - improved error diagnostics for all commands
973 - stradd/picadd: overwrite previous contents if entry already
974 exists, rather than returning errors
975 - stradd: use current stream if invoked without args
976 - faster (and hopefully more stable) ogg-vorbis handling
977 - para_krell: reap children to avoid zombie-flooding in case
978 no server is running
979 - si: report also server pid
980 - server: don't busy-loop if dbtool reports only invalid files.
981 - gui: CTRL+C works again, fix stream_read command line option
982 - fix pic_add, hist
983 - fix mysql dbtool startup in case no database exists
984 - many small fixes and cleanups
985
986 ---------------------------------------
987 0.1.3: (2004-12-10) "vanishing inertia"
988 ---------------------------------------
989
990 Starting from this release, the database tools are integrated in the
991 server binary. This decreases server startup time, reduces code size
992 and speeds up database commands. However, the layout of the underlying
993 mysql database changed only slightly and 0.1.3 should be backwards
994 compatible in that respect.
995
996 Visible changes:
997
998 - If mysql is not detected at compile time, or fails to init
999 at runtime, fall back to the dopey database tool which should
1000 always work.
1001 - para_dbtool and dbtool.conf are gone. All mysql specific
1002 options are read from server.conf and are prefixed by 'mysql_'.
1003 - new command: cdt (change database tool)
1004 - new command line option: dbtool (choose startup database tool)
1005 - The name of current stream is now stored in the database,
1006 so paraslash remembers its current stream when restarted.
1007 - new command: csp (change stream and play)
1008 - para_gui also reports current database tool and server uptime
1009
1010 -------------------------------------------
1011 0.1.2: (2004-11-28) "spherical fluctuation"
1012 -------------------------------------------
1013
1014 Point release before the big dbtool changes go in.
1015
1016 - dbtool: rename ca to cam (copy all meta data). It now also
1017 copies numplayed and lastplayed time as well as the picture
1018 id.
1019 - fix endless-loop-bug caused by mp3 files with invalid header
1020
1021 -----------------------------------------
1022 0.1.1: (2004-11-05) "floating atmosphere"
1023 -----------------------------------------
1024
1025 - gkrellm plugin
1026 - new dbtool command: mbox. Browse your sound-file collection
1027 with your favorite mail reader.
1028 - several small fixes
1029
1030 -------------------------------------
1031 0.1.0: (2004-10-22) "rotating cortex"
1032 -------------------------------------
1033
1034 - fix logging bug for loglevel > VERBOSE
1035 - fix skip command
1036 - correct timings for vbr mp3s
1037 - modular audio format support
1038 - ogg-vorbis support (experimental)
1039 - new server option: autoplay
1040
1041 -----------------------------------------
1042 0.0.99: (2004-07-25) "harmonic deviation"
1043 -----------------------------------------
1044
1045 - rename projectname from icc to paraslash (play, archive, rate
1046 and stream large audio sets happily)
1047 - paraslash is no longer restricted to one particular audio
1048 streaming software
1049 - new dbtool commands (stradd, strq, strdel) for easy stream
1050 managment w/o configuration file. That obsoletes stream_defs
1051 file/config option for dbtool.
