3
4 ---------------------------------------------
5 0.5.2 (to be announced) "orthogonal interior"
6 ---------------------------------------------
7
8 - The new sync filter synchronizes playback between multiple
9 clients.
10 - Major cleanup of the networking subsystem.
11 - Improved user manual.
12 - Minor fixes to avoid clang warnings.
13
14 ------------------------------------------
15 0.5.1 (2013-12-20) "temporary implication"
16 ------------------------------------------
17
18 Lots of fixes and improvements all over the place, and a major overhaul
19 of the build system.
20
21 - Audiod improvements and fixes.
22 - Buffer tree robustness improvements.
23 - Cleanup of the mood subsystem.
24 - Fixes and cleanups for the flac decoder.
25 - Latency improvements for the ogg/opus decoder.
26 - Crypto support is now optional. On systems without
27 openssl/gcrypt, the build succeeds but para_server,
28 para_audiod, para_client won't be built.
29 - The build system now works for cross-compile setups.
30 - The dependency tree has been flattened, which speeds up
31 builds and avoids to recreate the man pages on every change.
32 - The error code helper has been rewritten from perl to C,
33 which further improves build time.
34 - Many small bugs in the build system have been identified
35 and fixed.
36
37 ----------------------------------------
38 0.5.0 (2013-08-23) "invertible validity"
39 ----------------------------------------
40
41 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
42
43 - The sideband compatibility code has been removed, hence
44 sideband connections (introduced in 0.4.11) are now mandatory.
45 - Addblob commands can produce output.
46 - The stat command no longer sends garbage when para_server was
47 compiled against libgcrypt.
48 - Dependencies for gengetopt files are computed automatically.
49 This eliminates a constant source of build bugs.
50 - The setatt command now accepts file name patterns rather than only
51 path names.
52 - overview.pdf is now based on dia, a simple diagram creation program.
53 The new version is much more detailed and contains descriptions of
54 the various programs of the paraslash package.
55 - The separator of all multi-word options has been changed from
56 underscore to dash. For example --log_color becomes --log-color.
57 - Overhauled web pages and the new logo.

61
62 --------------------------------------
63 0.4.13 (2013-07-29) "spectral gravity"
64 --------------------------------------
65
66 One more 0.4.x release before the API-breaking changes for 0.5.0 go
67 in. The main features of this release are the ogg/opus audio format,
68 and UTF-8 support, but it includes also tons of other improvements
69 and fixes all over the place.
70
71 - New audio format: ogg/opus.
72 - UTF8 support for para_gui and the mp3 audio format handler.
73 - Scheduler improvements and fixes.
74 - The obsolete gettimeofday() function has been replaced
75 by clock_gettime() on systems which support it.
76 - Speed and usability improvements for para_gui.
77 - para_client now restores the fd flags of stdin and stdout
78 on shutdown.
79 - Improved manual pages.
80 - Consistent version strings for all executables.
81 - Reduced dependencies on generated files result in fewer
82 recompilations on changes.
83 - Performance improvements for the compress filter.
84 - Improved downloads web page.
85
86 -----------------------------------------
87 0.4.12 (2012-12-20) "volatile relativity"
88 -----------------------------------------
89 The new command line player, the resample filter, ALSA support for
90 para_fade, and the improved build system are the highlights of this
91 release which probably marks the end of the 0.4.x series.
92
93 - The afh receiver and the para_play executable.
94 - The resample filter: A sample rate converter based on
95 libsamplerate.
96 - The "versions" directory has been removed from the master
97 branch. The tarballs of the old releases are now available
98 in the new "releases" branch.
99 - Overhaul of the build system: All generated files are now
100 written to the "build" directory.
101 - The modular mixer API and the alsa mixer.
102 - Minor fixes for the osx writer.
103
104 --------------------------------------
105 0.4.11 (2012-07-20) "mutual diversity"
106 --------------------------------------
107
108 The major feature in this release is the new sideband API for
109 client-server communication. This API will be used exclusively starting
110 with 0.5.0, which breaks backward compatibility but allows to get rid
111 of quite some compatibility code. Other noteworthy changes include
112 decoder latency improvements and a long-standing bug fix for the
113 ALSA writer.
114
115 - Sideband connections: If both para_server and para_client
116 support this feature, data is sent as a multiplexed stream.
117 - The --no_default_filters option of para_filter has been
118 removed.
119 - Several fixes and latency improvements to various decoders.
120 - The ALSA writer now limits the prebuffer time to 500ms.
121 - Documentation improvements.
122 - Overhaul of the command_util.sh script.
123 - Fixes for some minor problems found by the clang analyzer.
124 - Compiles (almost) without warnings on gcc-3.
125 - Robustness improvements of the buffer tree code.
126
127 ------------------------------------------
128 0.4.10 (2012-03-30) "heterogeneous vacuum"
129 ------------------------------------------
130
131 Nothing earth-shaking in this release, but quite a few usability
132 improvements and the usual mix of cleanups and fixes.
133
134 - The --no_default_filters option of para_filter has been
135 deprecated. It still works but has no effect and will be
136 removed in the next version.
137 - para_gui now prints also the stderr output of the executing
138 command in the bottom window.
139 - Cleanup and consolidation of the various wrappers for
140 write(), writev(), send() and friends.
141 - The obscure error messages on mmap() failures have been
142 replaced by meaningful messages. This affects mainly
143 para_afh.
144 - para_audioc: Cleanups and memory leak fixes.
145 - Test 0004-server no longer fails if para_server is not
146 being built.
147 - New configure options: --with-id3tag-{headers,libs}.
148
149 -------------------------------------
150 0.4.9 (2011-12-06) "hybrid causality"
151 -------------------------------------
152
153 Support for another audio format, interactive mode for para_client
154 and para_audiod and many small improvements/fixes all over the place.
155
156 - Support for flac, the free lossless audio codec.
157 - Fix for an endless loop in the mp3 decoder for certain
158 (corrupt) mp3 files.
159 - When executed without specifying a command, para_client
160 and para_audioc start an interactive shell (requires
161 libreadline being installed). The interactive mode offers
162 full tab completion and command line history.
163 - autogen.sh now detects a distcc setup and adjusts the
164 parameter for the -j option of make accordingly.
165 - Shared memory areas are no longer restricted to 64K. We now
166 detect the maximal size of a shared memory area at runtime.
167 - cleanup of the internal uptime API.
168 - para_server prefaults the mmapped audio file to avoid
169 delays on slow media.
170 - A new test for the test-suite that exercises the
171 communication between para_server and para_audiod.
172 - The alsa writer eats up less CPU cycles when configured to
173 use the DMIX plugin.
174 - Simplified and unified receiver code.
175 - Makefile cleanups.
176 - Commands which print a list of matching audio files now
177 emit a meaningful error message if no audio file matched the
178 given pattern(s).
179
180 --------------------------------------
181 0.4.8 (2011-08-19) "nested assignment"
182 --------------------------------------
183
184 Gcrypt support, the overhauled osx writer and regex format specifiers
185 are the highlights of this release.
186
187 - support for libgcrypt as a drop-in replacement for openssl.
188 Run configure --enable-cryptolib=gcrypt to link against
189 libgcrypt. The two crypto implementations are compatible to
190 each other, i.e. a para_client executable linked against
191 gcrypt can connect to para_server linked against libssl
192 and vice versa.
193 - Rewrite of the osx writer (output plugin for Mac OS).
194 - audiod: The format specifier for receivers, filters and
195 writers is now treated as a regular expression. This allows
196 to replace 5 lines in the config file (one for each audio
197 format) by one single line. See the manual for details.
198 - The *.cmdline.[ch] files are no longer contained in the released
199 tarballs. This reduces the size of the tarballs but requires
200 gengetopt to build the tarball.
201 - Compiles cleanly also with llvm/clang.
202 - Corrupt mp3 files are handled more gracefully.
203 - The alsa writer uses poll fds instead of computing timeouts.
204 - Cleanup of the generic writer API.
205 - sched: Optimized zero timeouts.
206 - vss timeout cleanups.
207 - oggdec fixes and improvements.
208
209 --------------------------------------
210 0.4.7 (2011-06-01) "infinite rollback"
211 --------------------------------------
212
213 The new ao writer, support for ssh RSA keys and a couple of other
214 enhancements.
215
216 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
217 platforms through the libao audio library.
218 - Support for RSA keys generated with ssh-keygen.
219 - configure: improved options for ogg/vorbis/speex.
220 - The git version reported by --version always matches HEAD.
221 - The autogen script detects the number of processors and
222 runs a parallel make if possible.
223 - Major cleanup of the crypto API.
224 - Documentation updates.
225
226 ------------------------------------------
227 0.4.6 (2011-03-31) "deterministic entropy"
228 ------------------------------------------
229
230 Lots of ogg/vorbis improvements, the new test suite, enhancements
231 for para_gui and a fair amount of other bug fixes.
232
233 - For DCCP/OGG streams the audio file header is only sent once
234 at the beginning of the stream rather than periodically
235 every five seconds. This reduces network traffic and the
236 FEC group size.
237 - The vorbis comment header is replaced by an empty dummy header
238 before the header is sent over the network. This also results in
239 less network traffic and smaller FEC groups.
240 - The new "test" make target allows to perform some sanity checks prior
241 to installing the package.
242 - ogg timing fixes and performance improvements
243 - Scheduler improvements
244 - Proper exit codes for para_write
245 - para_gui: New option --theme to select a startup theme. Several
246 other improvements and fixes.
247 - aacdec error message cleanups
248 - simplified color error handling
249
250 --------------------------------------------
251 0.4.5 (2010-12-17) "symmetric randomization"
252 --------------------------------------------
253
254 Bug fixes, internal cleanups and variable-sized FEC slices.
255
256 - Contains a fix for an invalid-free-bug in the ogg audio format
257 handler code.
258 - Switching off the DCCP sender works again.
259 - para_audiod handles crashes of para_server more robustly.
260 - Internal scheduler and writer cleanups.
261 - Reduced latency due to variable-sized FEC slices.
262 - Improved documentation and error diagnostics.
263 - The build of para_server is now optional, allowing the build
264 to succeed in case libosl is not installed.
265
266 ------------------------------------------
267 0.4.4 (2010-08-06) "persistent regularity"
268 ------------------------------------------
269
270 Support for yet another audio format, para_write improvements and
271 bug fixes.
272
273 - Support for the speex codec.
274 - Support for sample formats other than 16 bit little endian.
275 - error2.h is now created by a perl script which speeds up configure
276 considerably.
277 - Fix a bug in the aac decoder which could lead to segfaults in
278 para_filter/para_audiod.
279 - Fixes for autoconf-2.66.
280
281 ----------------------------------------
282 0.4.3 (2010-07-05) "imaginary radiation"
283 ----------------------------------------
284
285 Many improvements for the DCCP and the UDP transport, the new user
286 manual and the usual mix of bug fixes and internal improvements.
287
288 - FEC support for the DCCP sender (Gerrit Renker). The new
289 --dccp_max_slice_size, --dccp_data_slices_per_group and
290 --dccp_slices_per_group options can be used to set the FEC
291 parameters for the DCCP transport.
292 - DNS lookups for UDP targets (Gerrit Renker).
293 - The new user manual replaces the README, README.afs, REQUIREMENTS
294 and INSTALL documents.
295 - Fix an end-of-file detection bug in the oggdec filter.
296 - The new nonblock API.
297 - Both options of the oggdec filter have been removed.
298 - New debug mode for the internal scheduler.
299
300 ------------------------------------------
301 0.4.2 (2010-04-23) "associative expansion"
302 ------------------------------------------
303
304 It's been some time since the last release, but finally here is
305 paraslash-0.4.2. The bulk of the changes comes from the new buffer
306 tree API, but there are changes all over the tree. Mainly performance
307 and usability improvements, but also quite some bug fixes.
308
309 - The new buffer tree API.
310 - DCCP: Support for CCID negotiation (Gerrit Renker).
311 - UDP robustness fixes.
312 - The --bufsize option for mp3dec is gone as it no longer makes sense
313 for the new buffer tree API.
314 - Fix audible buffer underruns for wma streams.
315 - The alsa writer no longer prints meaningless underrun durations.
316 - audiod: Defaults work also for udp streams. If no filter is
317 given for an audio format that is received via upd, fecdec is
318 automatically added as the first filter (along with the decoder).
319
320 ---------------------------------------
321 0.4.1 (2009-12-22) "concurrent horizon"
322 ---------------------------------------
323
324 Support for another audio format, minor feature enhancements and lots of bug
325 fixes. All fixes that have been accumulated in the maint branch (in particular
326 those mentionened in the 0.3.6 release notes) appear in this release as well.
327
328 - wma support.
329 - new afh option: --human to activate human-readable output.
330 - new server/audiod option: --log-timing to print timing information.
331 - build system improvements.
332 - source code documentation updates.
333
334 -------------------------------------
335 0.3.6 (2009-12-07) "cubic continuity"
336 -------------------------------------
337
338 Quite a few bugs have been found and fixed since 0.3.5, so here's
339 another 0.3.x release. No new features.
340
341 - Always check return value of malloc().
342 - ogg vorbis/FEC: Do not write garbage after the audio file header.
343 - exit if root privileges could not be dropped.
344 - FEC: Fix computation of extra slices.
345 - oss: Fix check for empty input buffer.
346 - Avoid buffer underruns due to filter chain output buffer constraints.
347 - server: Fix assignment of afs_pid.
348 - Don't panic if the afs database contains unknown audio formats.
349 - http/dccp: Do not send the audio file header twice.
350 - FEC: Timing improvements.
351
352 ----------------------------------------------
353 0.4.0 (2009-11-10) "simultaneous independence"
354 ----------------------------------------------
355
356 Two significant changes which require the new version number: The
357 improved authentication dialog and the fact that the database code
358 has been moved to a library, libosl. To use the new version, you have
359 to generate new RSA keys, see INSTALL for details. A shell script is
360 provided for conversion of the 0.3 database to the new 0.4 format.
361
362 - stronger crypto for client authentication
363 - the database code has been moved to a library
364 - improved status item handling
365 - cleanup of the build system
366 - The "-V" option now also prints the git version
367 - the new parser-friendly listing mode for the ls and stat commands
368 - mandatory rc4 encryption
369 - major audio format handler cleanups
370 - (id3,...) tags are no longer stored as a combined string in the database
371 - new mood methods: artist_matches, title_matches, comment_matches,
372 album_matches, year_maches, year.
373
374 --------------------------------------------
375 0.3.5 (2009-09-21) "symplectic separability"
376 --------------------------------------------
377
378 Full client support for *BSD Unixes, complete re-write of the ogg
379 vorbis audio format handler, various improvements all over the place
380 and the usual mix of bugfixes. This release marks the end of the 0.3
381 series if no serious problems show up.
382
383 - the new oss writer (supported on *BSD and Linux)
384 - rewrite of the ogg vorbis audio format handler. It's
385 recommended to replace the chunk tables of existing ogg
386 vorbis files in the afs database by re-adding these files
387 with "add -f".
388 - support for netmask subsets (Gerrit Renker)
389 - the new prebuffer filter
390 - improved signal handling
391 - variable fec output buffer size
392 - improved FEC timing fixes audible buffer underruns in UDP mode
393 - --log_color actually works
394 - new ls option: -d (print dates as seconds after the epoch)
395 - update to gengetopt 2.22.2
396 - support for RSA keys of size > 512 bits
397 - new option "mixer_channel" for para_fade
398
399 -----------------------------------------
400 0.3.4 (2009-05-07) "elliptic inheritance"
401 -----------------------------------------
402
403 The new udp sender, forward error correction, colored logs and various
404 other improvements. As the udp sender does not depend on any special
405 libraries, it is built unconditionally.
406
407 - The udp sender replaces the ortp sender. The new code uses forward
408 error correction to protect against packet losses. Many thanks to
409 Gerrit Renker for providing ipv6 support.
410 - The default port for udp streaming now defaults to 8000, like
411 for the http and the dccp senders/receivers.
412 - Loglevels are now specified as symbolic names, e.g.
413 "--loglevel info".
414 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
415 - para_server/para_audiod: Color support for log messages.
416 - new options for mp3dec: --ignore-crc, --bufsize
417 - new audiod option: --config-file.
418 - gengetopt cleanups.
419 - Improved help/man pages: The documentation of para_audiod,
420 para_recv, para_filter and para_write now also contains
421 all options of the available receivers/filters/writers. The
422 man page of para_fade contains a description of the different
423 modes of operation.
424 - More source code documentation.
425 - vss timing fixes.
426
427 --------------------------------------------
428 0.3.3 (2008-12-01) "axiomatic perspectivity"
429 --------------------------------------------
430
431 Internal code cleanups, bug fixes, improved tag handling and the new
432 amplification filter.
433
434 - para_server uses the generic scheduling code.
435 - overhaul of the virtual streaming system.
436 - mp3: id3 version 2 support via libid3tag (optional)
437 - ogg: vorbis comment support.
438 - aac meta info support.
439 - mp3 audio format handler cleanups.
440 - new filter: "amp" to amplify the amplitude of the audio stream
441 - new status item/database entry: amplification. It is
442 used by the amp filter to pre-amplify the audio stream.
443 - fix a close-without-open bug in para_write.
444 - fix a bug in com_init() which was introduced in 0.3.2.
445 - better error diagnostics for para_client.
446
447 -----------------------------------------
448 0.3.2 (2008-04-11) "probabilistic parity"
449 -----------------------------------------
450
451 The new para_afh executable, scheduling and documentation improvements.
452
453 - new ls option: -lc (list chunk table)
454 - new executable: para_afh, the stand-alone audio file handler tool
455 - afs commands can send output more than SHMMAX (32MB on Linux). This
456 also reduces the memory usage of commands that produce large amounts
457 of output.
458 - major scheduler and audiod cleanups.
459 - more detailed and much nicer man pages.
460
461 ---------------------------------------
462 0.3.1 (2008-02-23) "liquid interaction"
463 ---------------------------------------
464
465 A mix of cleanups, bug fixes, improvements, and some new features. No
466 significant changes to the new database (osl) code, which is generally
467 a good sign.
468
469 - Share some similar/duplicate code between the http and the
470 dccp sender.
471 - Generic access control lists for paraslash senders.
472 - dccp sender: Access control lists, connection limiting and support
473 for the allow,deny,on,off,help sender commands.
474 - The default dccp port changed from 5001 to 8000 (suggested by
475 Gerrit Renker).
476 - para_server starts even if not all public keys could be loaded.
477 - Audiod performance improvements.
478 - fix a bug in the "off" command of the http sender.
479 - fix some fd and memory leaks.
480 - Update to gengetopt-2.22.
481
482 -------------------------------------
483 0.3.0 (2008-01-12) "solar saturation"
484 -------------------------------------
485
486 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
487
488
489 Usually one might expect lots of new features AND a big increase in size
490 for a major release like this.
491
492 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
493 ever. The decrease in size is mostly due to the removal of some
494 graphical tools (which were only quick hacks anyway). But also the
495 fact that the mysql code is gone cuts down the size a bit.
496
497 Being independent of mysql comes at a cost: The fact that paraslash
498 now contains its own database (the object storage layer, osl) increases
499 the (stripped) binary size of para_server by ~50K on i386.
500
501 - no more restrictions on unique basenames.
502 - independent of mysql: The new self-contained object
503 storage layer (osl) replaces the mysql database.
504 - New executable para_fsck: Check integrity of osl tables.
505 - Lyrics support.
506 - Reliable audio file move/rename detection.
507 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
508 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
509 Solaris (sparc64).
510 - the new osl-based audio file selector (afs) replaces the random,
511 the playlist and the mysql selector of paraslash-0.2.x.
512 - IPv6 support (thanks to Gerrit Renker).
513 - paraslash-0.2.x streams are now called "moods". Writing
514 0.3.x-mood definitions should be both easier and more
515 powerful than writing 0.2.x-stream definitions.
516 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
517 been removed. The world is a better place without them. However,
518 para_gui is still there.
519 - afs tracks audio file selection also in playlist mode.
520 - few easy-to-use afs commands replace the many not-so-easy-to-use
521 mysql commands (and are available also in playlist mode).
522 - Improved error subsystem.
523 - The earth-shaking new logo.
524
525 -----------------------------------------
526 0.2.17 (2007-11-20) "isotropic threshold"
527 -----------------------------------------
528
529 Mainly bugfixes and cleanups in this version which marks the end of
530 the 0.2.x series if no serious bugs show up after the release.
531
532 - mysql_selector: fix a locking bug.
533 - universal chunk queueing.
534 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
535 to Gerrit Renker).
536 - be more carful wrt. signed vs. unsigned argument passing.
537 - cleanup error.h and fix some references to invalid error
538 codes.
539 - update to gengetopt-2.21.
540 - update to ortp-0.13.1.
541 - autoconf: extend checks for headers, library functions and
542 compiler characteristics.
543 - Fix streaming of large mp3 files.
544 - Fix an off-by-one bug in playlist handling.
545
546 --------------------------------------
547 0.2.16 (2007-04-05) "neural discharge"
548 --------------------------------------
549
550 The main change in this release is the major audio format handler
551 cleanup which removes some similar/duplicate code and makes it easier
552 to implement plugins for other audio formats. Of course, the usual mix
553 of other improvements/changes/bugfixes also made it into the release.
554
555 - simplified audio format handlers (most of the handling functions
556 were moved one layer up to the virtual streaming system).
557 - para_server uses mmap to read audio files
558 - repositioning of mp3 streams is much faster, in particular for
559 jumping near the end of large mp3 files.
560 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
561 and AFS_WRITE.
562 - fix a bug in para_filter that caused decoding of aac files
563 to start only after a few seconds.
564 - fix osx_writer hangs
565 - simplified dccp code (thanks to Gerrit Renker)
566 - the compress filter works also on big endian systems (ppc)
567
568 -----------------------------------------
569 0.2.15 (2007-02-16) "inductive resonance"
570 -----------------------------------------
571
572 Minor improvements, more documentation and a bunch of bug fixes.
573
574 - para_server: The server.users file is only read once on server
575 startup rather than for each connection
576 - mp3dec: Fix decoding of corrupt mp3 files
577 - afs (audio file sender) is now called vss (virtual streaming
578 system). Consequently, the permission flags specified in
579 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
580 become VSS_READ and VSS_WRITE respectively.
581 - para_audiod/para_filter: Fix a bug that caused the last chunk
582 of audio data not being written under certain circumstances
583 - audiod: compute the difference of server time and local time
584 correctly
585 - para_server/para_audiod: Fix some memory leaks
586 - documentation improvements
587 - configure.ac: fix checks for para_krell
588 - new man pages
589
590 -------------------------------------------
591 0.2.14 (2006-10-15) "transient singularity"
592 -------------------------------------------
593
594 The only major enhancement of this version is the osx writer which completes
595 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
596 until now for reasons beyond the scope of this changelog entry.
597
598 - new output plugin for Mac Os: the osx writer
599 - rename configure command line options from --enable-xxx-headers to
600 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
601 - configure: new command line options: --with-mad-headers,
602 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
603 - some robustness fixes
604 - dymamic audio format recognition for audiod
605 - para_server: new command line option: --autoplay_delay
606 - para_audiod: new command line option: --clock_diff_count
607
608 ---------------------------------------
609 0.2.13 (2006-07-14) "sonic convolution"
610 ---------------------------------------
611
612 A bunch of new features and core changes.
613
614 - the new paraslash scheduler, short and sweet.
615 - Support for m4a/mp4 files via the new aac audio format
616 handler/filter (requires libfaad).
617 - each writer has its own command line parser, just like
618 para_recv and para_filter.
619 - para_client and para_audioc use the error subsystem
620 - writers are integrated in para_audiod (currently linux-only)
621 - para_client is integrated in para_audiod
622 - random/playlist selector: improved info strings
623 - new audiod commands: tasks, kill
624 - update to libortp-0.10.1
625 - para_fade: wake time defaults to 8 hours from now
626 - update to autoconf-2.60
627
628 ------------------------------------------
629 0.2.12 (2006-05-12) "oriented abstraction"
630 ------------------------------------------
631
632 Many user-visible changes in this release and lots of new
633 features:
634
635
636 - the new optional dccp sender/receiver. It uses the datagram
637 congestion control protocol. You'll need a fairly new kernel
638 for this.
639 - paraslash works on Mac OS X (thanks to Gerd Becker)
640 - para_play renamed to para_write
641 - modular output plugin design (writers) for para_write
642 - new file_writer output plugin for para_write
643 - compress filter speed improvements
644 - update to libortp-0.9.1
645 - update to gengetopt-2.17rc
646 - para_client no longer depends on libreadline (as the
647 code for the interactive mode was removed).
648 - gcc-2-95 is no longer a supported compiler. It may still
649 work, but it gets no more testing.
650 - the tarball no longer contains the screenshot images which
651 reduces its size quite a bit.
652 - configure: new command line options: --enable-mysql-headers
653 and --enable-mysql-libs
654
655 ------------------------------------
656 0.2.11 (2006-03-11) "atomic duality"
657 ------------------------------------
658
659 Here it is, the first paraslash release developed with git. There
660 are fairly many user-visible changes in this release. As two out of
661 the three "database tools" of paraslash don't use a database at all,
662 they are now called "audio file selectors" instead.
663
664
665 - the cdt command (change database tool) becomes chs (change
666 selector)
667 - no more colon separators: The syntax of some options of
668 para_audiod and para_filter have changed. Use --help for
669 more info (and some examples).
670 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
671 - switch from cvs to git (should've done that earlier)
672 - the new ipc subsystem
673 - new audio file selector: playlist
674 - para_server: the dopey selector is now called "random",
675 and is the default selector. Use the --selector option to
676 choose another selector at startup, or the chs command to
677 change the selector at runtime.
678 - X86_64 fixes (thanks to Steffen Klassert)
679 - para_play fixes
680
681 --------------------------------------
682 0.2.10 (2006-02-17) "cyclic attractor"
683 --------------------------------------
684
685 Huge documentation update, a scrollable window for para_gui, ortp
686 improvements, and of course many small fixes not mentioned here.
687 The diffstat below is rather misleading as most insertions are due
688 to the new source documentation.
689
690 - autoconf cleanup
691 - para_server also uses the new error subsystem
692 - lots of new documentation (UTSL)
693 - gui improvements:
694 - keysyms for cursor keys and for next/previous page keys
695 - scrollable output window
696 - new internal commands: scroll up/down, page up/down
697 - fix color of command output.
698 - ortp: the --chunk_time and --header flags are no longer needed
699 for para_recv/para_audiod as this information is now encoded in
700 each rtp packet sent by para_server.
701
702 -------------------------------------------
703 0.2.9 (2006-01-24) "progressive turbulence"
704 -------------------------------------------
705
706 Internal audiod receivers/filters, the new error subsystem and
707 a lot of small improvements.
708
709 - para_recv and para_filter are integrated into the para_audiod
710 binary, i.e. audiod no longer spawns a new process for
711 each receiver/filter. As para_recv and para_filter might be
712 useful as standalone programs, they still get built (linked
713 against the same object files that are also used for audiod).
714 - further ortp timing improvements should reduce the CPU usage
715 of the ortp receiver.
716 - improved audio grabbing. The 'grab' command of para_audiod
717 has its own set of command line options. Read the output of
718 "para_audioc help grab" for more info.
719 - oggdec: configurable input prebuffer size.
720 - the new error subsystem gives better error diagnostics
721 and reduces code size.
722
723 -----------------------------------------
724 0.2.8 (2006-01-02) "dynamic accumulation"
725 -----------------------------------------
726
727 The new modular filter design and the para_play-hangs bugfix.
728
729 - new executable: para_filter. It combines para_mp3dec,
730 para_oggdec and para_compress. It also adds a further filter
731 type, wav, that just inserts a wave header at the desired point
732 of the filter chain. All 'piping' is done in-memory (i.e. no
733 read/write operations are used).
734 - para_play: fix a stupid bug that caused it to hang under
735 certain circumstances.
736
737 -------------------------------------------
738 0.2.7 (2006-12-27) "transparent invariance"
739 -------------------------------------------
740
741 Not many user-visible changes but a fair amount of internal improvements.
742
743
744 - The http sender buffers data if it can not be sent
745 out immediately (because the socket is not writable). This
746 should prevent para_server from shutting down the connection
747 too early on a loaded network.
748 - para_play also prebuffers data if it is told to start at a
749 future time by the --start_time option.
750 - The return of para_recv: It combines para_ortp_recv and
751 para_http_recv. Use the --receiver option to switch between
752 the two. para_recv builds without libortp, but contains
753 only the http receiver in this case.
754 - update to ortp 0.8.1. As this ortp release contains incompatible
755 changes, para_recv-0.2.7 won't link against older ortp libs.
756 - improved ortp timings.
757 - use of gcc-extensions that #define away for non-gcc and
758 gcc < 3.0.
759
760 -------------------------------------------
761 0.2.6 (2005-10-29) "recursive compensation"
762 -------------------------------------------
763
764 Transparent session encryption (uses openssl's Alleged RC4 cipher),
765 the internal find command and several other improvements and cleanups.
766
767 - Encrypt the session if encryption is requested by the client
768 (default for para_client 0.2.6). This is backwards
769 compatible, so older clients can still connect to para_server
770 0.2.6. Use the new client option --plain to request an
771 uncrypted session (off by default, must be set to on in
772 order to connect to para_server 0.2.x with 0 <= x <= 5).
773 - para_server uses an internal function to locate audio files
774 rather than calling find(1). The server option
775 --mysql_audio_file_dir replaces --mysql_find_cmd.
776 - documentation update
777 - man pages
778 - header file cleanup
779 - para_client code cleanup
780 - para_gui: faster display of output of display commands
781
782 ------------------------------------------
783 0.2.5 (2005-10-13) "aggressive resolution"
784 ------------------------------------------
785
786 This release adds internal senders, i.e. no more external programs are
787 spawned for sending out the audio data. There are two different senders
788 available: The http sender and the ortp sender (former para_send which
789 is no longer needed).
790
791 The new sender code has a plugin-like design so it can be easily
792 extended should there be be any future need for supporting another
793 network streaming protocol. All senders are completely independent of
794 each other. In particular, the http and the ortp sender can operate
795 in parallel.
796
797 - new server command: sender to control senders at runtime.
798 Read the output of "para_server -h" and "para_client help
799 sender" for more information.
800 - para_recv renamed to para_ortp_recv
801 - new executable: para_http_recv, a simple command line
802 http receiver.
803 - major afs/mp3/ogg code simplifications due to internal
804 senders.
805 - ogg timing improvements
806 - fix several minor memory leaks (found by valgrind)
807 - empty stream definitions work again
808 - com_ne(): ignore errors on remove
809 - audiod: fix segfault on server restart
810
811 ---------------------------------------
812 0.2.4 (2005-09-21) "toxic anticipation"
813 ---------------------------------------
814
815 Several small improvements, fixes and the new grab command.
816
817 - audiod:
818 - new command: "grab" to grab the output of the stream reader
819 or any filters. Read the output of "para_audioc help grab"
820 for more information.
821 - fix memory leak
822 - code cleanup
823 - audioc: new command line option: --bufsize to specify a
824 buffer size different from the default size 8192.
825 - improved error diagnostics for para_play.
826 - new configure option: --enable-ssldir so search for openssl in
827 non-standard places
828 - sdl_gui: Make it look nice again for 1024x768
829 - server: report total size of memory allocated with sbrk by malloc,
830 new command line option: --announce_time
831
832 -----------------------------------------
833 0.2.3 (2005-09-01) "hydrophilic movement"
834 -----------------------------------------
835
836 Two new executables and major feature enhancements.
837
838 - audiod filters: It is now possible to specify arbitrary many
839 (including none) filters for each supported audio
840 format. This can be used e.g. for normalizing volume,
841 transforming or grabbing the audio stream, or for using
842 visualizers. Read the output of "para_audiod -h" for the
843 syntax of the new --filter_cmd option.
844 - new executable: para_play, a tiny alsa player. It
845 can play wave files or raw pcm (16 bit little endian)
846 from stdin.
847 - new executable: para_compress, a dynamic range compressor
848 intended to keep audio output at a consistent volume. Derived
849 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
850 - audiod: New option: --stream_delay. This can be used in
851 a local network to syncronize the audio output of all
852 clients that play the same stream.
853
854 ------------------------------------------
855 0.2.2 (2005-08-19) "tangential excitation"
856 ------------------------------------------
857
858 Mostly internal changes in this release, but also some new commands
859 for the mysql database tool.
860
861 - cleanup exec.c, fix para_exec bug
862 - compile time loglevel (log messages below the given level
863 won't be compiled in, which reduces the size of the
864 resulting binaries)
865 - new log macros that shorten the size of the source code.
866 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
867 to send only zeros. With this workaround, para_audioc works
868 again.
869 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
870 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
871 (new entry), "snp" (set numplayed). Read the manual for more
872 information.
873
874 ---------------------------------------
875 0.2.1 (2005-08-15) "surreal experience"
876 ---------------------------------------
877
878 Here comes paraslash-0.2.1. It contains a couple of new features and,
879 surprise, only minor bug fixes.
880
881 - kill noisy mp3 debug message
882 - cleanup of the build system
883 - para_server and para_client directly use the crypto routines
884 of the openssl library rather than invoking the openssl command
885 line utitlity
886 - server/audiod: new option --user to switch to the given user
887 when invoked as root. Read the output of "para_server -h" for
888 more information.
889 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
890 status. Default: "para_audioc stat"
891 - sdl_gui: new option --pic_cmd to be used to download the picture.
892 Default: "para_client pic"
893 - audiod: 5 slots ought to be enough for everybody
894 - audiod: new status item: Uptime, kill hup command
895
896 ------------------------------------------
897 0.2.0 (2005-08-06) "distributed diffusion"
898 ------------------------------------------
899
900 After several month of increased development activity, paraslash-0.2.0
901 has arrived. It contains many new features and is much more
902 self-contained than the old 0.1.x series. Enjoy!
903
904
905 - para_server: fix hang on song change and crash on sighup.
906 Speed up mysql queries. The DIR_LIKE macro is gone.
907 - new executables: para_audiod, the local audio daemon that
908 starts playback (uses SCM_CREDENTIALS socket magic) and
909 para_audioc, the corresponding client.
910 - new executables: para_mp3dec/para_oggdec, two really teensy
911 decoders. para_mp3dec is based on libmad, para_oggdec requires
912 libvorbisfile.
913 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
914 they are now called para_send and para_recv respectively.
915 - documentation updates
916 - para_gui is themable. For now there is the default theme that
917 looks as before and the simple theme: blue and easy.
918 - gui: audio streaming is now handled by audiod. Time display shows
919 playback time rather than streaming time
920 - slider: update to libzmw-0.2.0
921 - para_krell: fix crash on server shutdown
922 - switch from gzip to bzip2
923
924 ----------------------------------------
925 0.1.7 (2005-04-18) "melting penetration"
926 ----------------------------------------
927
928 The main change in this release is clearly the oggvorbis rewrite,
929 but there are also lots of smaller changes. If you intend to use both
930 the mp3 and the ogg plugin, it is recommended to use software mixing,
931 e.g. the dmix plugin which is provided by ALSA.
932
933 - new executables: para_ovsend and para_ovrecv for sending/receiving
934 oggvorbis files via rtp. Requires the open rtp library. Get it at
935 http://www.linphone.org/ortp/
936 - rewrite of the ogg_vorbis core code
937 - configure detects libzmw and, if detected, includes
938 para_slider to the list of binaries to be built by make
939 - server stream writers read from their associated fifo rather
940 than from stdin
941 - slider: two new sliders, lastplayed and numplayed
942 - fix nasty double free bug which caused random segfaults in case of
943 mp3 files with invalid header information
944 - gui: new command line option: --stream_timeout=seconds to
945 deactivate a slot if it is idle for that many seconds (default=`5')
946 - diffstats
947
948 ---------------------------------------
949 0.1.6 (2005-03-05) "asymptotic balance"
950 ---------------------------------------
951
952 Only little user-visible changes in this release. Mainly bugfixes and
953 core code cleanup. This is probably the most stable version ever if you
954 stick to mp3...
955
956 - fix several memory leaks
957 - rename default name of mysql database from "music" to "paraslash".
958 Use para_server's --mysql_database option if you do not want to
959 rename your old database.
960 - rework ogg vorbis code
961 - make update command work on mysql servers with LOCAL_INFILE
962 disabled
963 - gui: improved stream I/O (slots)
964 - simplified audio format API
965 - para_pob_ogg is gone
966
967 ------------------------------------
968 0.1.5 (2004-12-31) "opaque eternity"
969 ------------------------------------
970
971 Let's slide gently into the new year.
972
973 - new: para_slider (not built automatically, type "make
974 para_slider" to build). A toy for those who always felt that
975 creating stream definitions is difficult. See screenshots,
976 README and FEATURES for more info.
977 - improved signal handling. Fixes server segfault on SIGHUP
978 for linux kernels newer than Aug 24 2004 and makes para_gui
979 race-free.
980 - reload database tool on SIGHUP
981 - improved help message for sl
982 - do not log "broken pipe" messages as errors. They are
983 perfectly ok.
984 - fix wrong error message on permission errors
985
986 -----------------------------------------
987 0.1.4 (2004-12-19) "tunneling transition"
988 -----------------------------------------
989
990 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
991 Hopefully, most of them got wiped out with this release. Some
992 enhancements went also in.
993
994 - improved error diagnostics for all commands
995 - stradd/picadd: overwrite previous contents if entry already
996 exists, rather than returning errors
997 - stradd: use current stream if invoked without args
998 - faster (and hopefully more stable) ogg-vorbis handling
999 - para_krell: reap children to avoid zombie-flooding in case
1000 no server is running
1001 - si: report also server pid
1002 - server: don't busy-loop if dbtool reports only invalid files.
1003 - gui: CTRL+C works again, fix stream_read command line option
1004 - fix pic_add, hist
1005 - fix mysql dbtool startup in case no database exists
1006 - many small fixes and cleanups
1007
1008 ---------------------------------------
1009 0.1.3: (2004-12-10) "vanishing inertia"
1010 ---------------------------------------
1011
1012 Starting from this release, the database tools are integrated in the
1013 server binary. This decreases server startup time, reduces code size
1014 and speeds up database commands. However, the layout of the underlying
1015 mysql database changed only slightly and 0.1.3 should be backwards
1016 compatible in that respect.
1017
1018 Visible changes:
1019
1020 - If mysql is not detected at compile time, or fails to init
1021 at runtime, fall back to the dopey database tool which should
1022 always work.
1023 - para_dbtool and dbtool.conf are gone. All mysql specific
1024 options are read from server.conf and are prefixed by 'mysql_'.
1025 - new command: cdt (change database tool)
1026 - new command line option: dbtool (choose startup database tool)
1027 - The name of current stream is now stored in the database,
1028 so paraslash remembers its current stream when restarted.
1029 - new command: csp (change stream and play)
1030 - para_gui also reports current database tool and server uptime
1031
1032 -------------------------------------------
1033 0.1.2: (2004-11-28) "spherical fluctuation"
1034 -------------------------------------------
1035
1036 Point release before the big dbtool changes go in.
1037
1038 - dbtool: rename ca to cam (copy all meta data). It now also
1039 copies numplayed and lastplayed time as well as the picture
1040 id.
1041 - fix endless-loop-bug caused by mp3 files with invalid header
1042
1043 -----------------------------------------
1044 0.1.1: (2004-11-05) "floating atmosphere"
1045 -----------------------------------------
1046
1047 - gkrellm plugin
1048 - new dbtool command: mbox. Browse your sound-file collection
1049 with your favorite mail reader.
1050 - several small fixes
1051
1052 -------------------------------------
1053 0.1.0: (2004-10-22) "rotating cortex"
