4 ----------------------------------------------
5 0.5.1 (to be announced) "temporary implication"
6 ----------------------------------------------
7
8 - audiod improvements and fixes.
9 - buffer tree robustness improvements.
10
11 ----------------------------------------
12 0.5.0 (2013-08-23) "invertible validity"
13 ----------------------------------------
14
15 Some API-breaking changes, one serious bug fix, and a lot of bike-shedding.
16
17 - The sideband compatibility code has been removed, hence
18 sideband connections (introduced in 0.4.11) are now mandatory.
19 - Addblob commands can produce output.
20 - The stat command no longer sends garbage when para_server was
21 compiled against libgcrypt.
22 - Dependencies for gengetopt files are computed automatically.
23 This eliminates a constant source of build bugs.
24 - The setatt command now accepts file name patterns rather than only
25 path names.
26 - overview.pdf is now based on dia, a simple diagram creation program.
27 The new version is much more detailed and contains descriptions of
28 the various programs of the paraslash package.
29 - The separator of all multi-word options has been changed from
30 underscore to dash. For example --log_color becomes --log-color.
31 - Overhauled web pages and the new logo.

36 --------------------------------------
37 0.4.13 (2013-07-29) "spectral gravity"
38 --------------------------------------
39
40 One more 0.4.x release before the API-breaking changes for 0.5.0 go
41 in. The main features of this release are the ogg/opus audio format,
42 and UTF-8 support, but it includes also tons of other improvements
43 and fixes all over the place.
44
45 - New audio format: ogg/opus.
46 - UTF8 support for para_gui and the mp3 audio format handler.
47 - Scheduler improvements and fixes.
48 - The obsolete gettimeofday() function has been replaced
49 by clock_gettime() on systems which support it.
50 - Speed and usability improvements for para_gui.
51 - para_client now restores the fd flags of stdin and stdout
52 on shutdown.
53 - Improved manual pages.
54 - Consistent version strings for all executables.
55 - Reduced dependencies on generated files result in fewer
56 recompilations on changes.
57 - Performance improvements for the compress filter.
58 - Improved downloads web page.
59
60 -----------------------------------------
61 0.4.12 (2012-12-20) "volatile relativity"
62 -----------------------------------------
63 The new command line player, the resample filter, ALSA support for
64 para_fade, and the improved build system are the highlights of this
65 release which probably marks the end of the 0.4.x series.
66
67 - The afh receiver and the para_play executable.
68 - The resample filter: A sample rate converter based on
69 libsamplerate.
70 - The "versions" directory has been removed from the master
71 branch. The tarballs of the old releases are now available
72 in the new "releases" branch.
73 - Overhaul of the build system: All generated files are now
74 written to the "build" directory.
75 - The modular mixer API and the alsa mixer.
76 - Minor fixes for the osx writer.
77
78 --------------------------------------
79 0.4.11 (2012-07-20) "mutual diversity"
80 --------------------------------------
81
82 The major feature in this release is the new sideband API for
83 client-server communication. This API will be used exclusively starting
84 with 0.5.0, which breaks backward compatibility but allows to get rid
85 of quite some compatibility code. Other noteworthy changes include
86 decoder latency improvements and a long-standing bug fix for the
87 ALSA writer.
88
89 - Sideband connections: If both para_server and para_client
90 support this feature, data is sent as a multiplexed stream.
91 - The --no_default_filters option of para_filter has been
92 removed.
93 - Several fixes and latency improvements to various decoders.
94 - The ALSA writer now limits the prebuffer time to 500ms.
95 - Documentation improvements.
96 - Overhaul of the command_util.sh script.
97 - Fixes for some minor problems found by the clang analyzer.
98 - Compiles (almost) without warnings on gcc-3.
99 - Robustness improvements of the buffer tree code.
100
101 ------------------------------------------
102 0.4.10 (2012-03-30) "heterogeneous vacuum"
103 ------------------------------------------
104
105 Nothing earth-shaking in this release, but quite a few usability
106 improvements and the usual mix of cleanups and fixes.
107
108 - The --no_default_filters option of para_filter has been
109 deprecated. It still works but has no effect and will be
110 removed in the next version.
111 - para_gui now prints also the stderr output of the executing
112 command in the bottom window.
113 - Cleanup and consolidation of the various wrappers for
114 write(), writev(), send() and friends.
115 - The obscure error messages on mmap() failures have been
116 replaced by meaningful messages. This affects mainly
117 para_afh.
118 - para_audioc: Cleanups and memory leak fixes.
119 - Test 0004-server no longer fails if para_server is not
120 being built.
121 - New configure options: --with-id3tag-{headers,libs}.
122
123 -------------------------------------
124 0.4.9 (2011-12-06) "hybrid causality"
125 -------------------------------------
126
127 Support for another audio format, interactive mode for para_client
128 and para_audiod and many small improvements/fixes all over the place.
129
130 - Support for flac, the free lossless audio codec.
131 - Fix for an endless loop in the mp3 decoder for certain
132 (corrupt) mp3 files.
133 - When executed without specifying a command, para_client
134 and para_audioc start an interactive shell (requires
135 libreadline being installed). The interactive mode offers
136 full tab completion and command line history.
137 - autogen.sh now detects a distcc setup and adjusts the
138 parameter for the -j option of make accordingly.
139 - Shared memory areas are no longer restricted to 64K. We now
140 detect the maximal size of a shared memory area at runtime.
141 - cleanup of the internal uptime API.
142 - para_server prefaults the mmapped audio file to avoid
143 delays on slow media.
144 - A new test for the test-suite that exercises the
145 communication between para_server and para_audiod.
146 - The alsa writer eats up less CPU cycles when configured to
147 use the DMIX plugin.
148 - Simplified and unified receiver code.
149 - Makefile cleanups.
150 - Commands which print a list of matching audio files now
151 emit a meaningful error message if no audio file matched the
152 given pattern(s).
153
154 --------------------------------------
155 0.4.8 (2011-08-19) "nested assignment"
156 --------------------------------------
157
158 Gcrypt support, the overhauled osx writer and regex format specifiers
159 are the highlights of this release.
160
161 - support for libgcrypt as a drop-in replacement for openssl.
162 Run configure --enable-cryptolib=gcrypt to link against
163 libgcrypt. The two crypto implementations are compatible to
164 each other, i.e. a para_client executable linked against
165 gcrypt can connect to para_server linked against libssl
166 and vice versa.
167 - Rewrite of the osx writer (output plugin for Mac OS).
168 - audiod: The format specifier for receivers, filters and
169 writers is now treated as a regular expression. This allows
170 to replace 5 lines in the config file (one for each audio
171 format) by one single line. See the manual for details.
172 - The *.cmdline.[ch] files are no longer contained in the released
173 tarballs. This reduces the size of the tarballs but requires
174 gengetopt to build the tarball.
175 - Compiles cleanly also with llvm/clang.
176 - Corrupt mp3 files are handled more gracefully.
177 - The alsa writer uses poll fds instead of computing timeouts.
178 - Cleanup of the generic writer API.
179 - sched: Optimized zero timeouts.
180 - vss timeout cleanups.
181 - oggdec fixes and improvements.
182
183 --------------------------------------
184 0.4.7 (2011-06-01) "infinite rollback"
185 --------------------------------------
186
187 The new ao writer, support for ssh RSA keys and a couple of other
188 enhancements.
189
190 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
191 platforms through the libao audio library.
192 - Support for RSA keys generated with ssh-keygen.
193 - configure: improved options for ogg/vorbis/speex.
194 - The git version reported by --version always matches HEAD.
195 - The autogen script detects the number of processors and
196 runs a parallel make if possible.
197 - Major cleanup of the crypto API.
198 - Documentation updates.
199
200 ------------------------------------------
201 0.4.6 (2011-03-31) "deterministic entropy"
202 ------------------------------------------
203
204 Lots of ogg/vorbis improvements, the new test suite, enhancements
205 for para_gui and a fair amount of other bug fixes.
206
207 - For DCCP/OGG streams the audio file header is only sent once
208 at the beginning of the stream rather than periodically
209 every five seconds. This reduces network traffic and the
210 FEC group size.
211 - The vorbis comment header is replaced by an empty dummy header
212 before the header is sent over the network. This also results in
213 less network traffic and smaller FEC groups.
214 - The new "test" make target allows to perform some sanity checks prior
215 to installing the package.
216 - ogg timing fixes and performance improvements
217 - Scheduler improvements
218 - Proper exit codes for para_write
219 - para_gui: New option --theme to select a startup theme. Several
220 other improvements and fixes.
221 - aacdec error message cleanups
222 - simplified color error handling
223
224 --------------------------------------------
225 0.4.5 (2010-12-17) "symmetric randomization"
226 --------------------------------------------
227
228 Bug fixes, internal cleanups and variable-sized FEC slices.
229
230 - Contains a fix for an invalid-free-bug in the ogg audio format
231 handler code.
232 - Switching off the DCCP sender works again.
233 - para_audiod handles crashes of para_server more robustly.
234 - Internal scheduler and writer cleanups.
235 - Reduced latency due to variable-sized FEC slices.
236 - Improved documentation and error diagnostics.
237 - The build of para_server is now optional, allowing the build
238 to succeed in case libosl is not installed.
239
240 ------------------------------------------
241 0.4.4 (2010-08-06) "persistent regularity"
242 ------------------------------------------
243
244 Support for yet another audio format, para_write improvements and
245 bug fixes.
246
247 - Support for the speex codec.
248 - Support for sample formats other than 16 bit little endian.
249 - error2.h is now created by a perl script which speeds up configure
250 considerably.
251 - Fix a bug in the aac decoder which could lead to segfaults in
252 para_filter/para_audiod.
253 - Fixes for autoconf-2.66.
254
255 ----------------------------------------
256 0.4.3 (2010-07-05) "imaginary radiation"
257 ----------------------------------------
258
259 Many improvements for the DCCP and the UDP transport, the new user
260 manual and the usual mix of bug fixes and internal improvements.
261
262 - FEC support for the DCCP sender (Gerrit Renker). The new
263 --dccp_max_slice_size, --dccp_data_slices_per_group and
264 --dccp_slices_per_group options can be used to set the FEC
265 parameters for the DCCP transport.
266 - DNS lookups for UDP targets (Gerrit Renker).
267 - The new user manual replaces the README, README.afs, REQUIREMENTS
268 and INSTALL documents.
269 - Fix an end-of-file detection bug in the oggdec filter.
270 - The new nonblock API.
271 - Both options of the oggdec filter have been removed.
272 - New debug mode for the internal scheduler.
273
274 ------------------------------------------
275 0.4.2 (2010-04-23) "associative expansion"
276 ------------------------------------------
277
278 It's been some time since the last release, but finally here is
279 paraslash-0.4.2. The bulk of the changes comes from the new buffer
280 tree API, but there are changes all over the tree. Mainly performance
281 and usability improvements, but also quite some bug fixes.
282
283 - The new buffer tree API.
284 - DCCP: Support for CCID negotiation (Gerrit Renker).
285 - UDP robustness fixes.
286 - The --bufsize option for mp3dec is gone as it no longer makes sense
287 for the new buffer tree API.
288 - Fix audible buffer underruns for wma streams.
289 - The alsa writer no longer prints meaningless underrun durations.
290 - audiod: Defaults work also for udp streams. If no filter is
291 given for an audio format that is received via upd, fecdec is
292 automatically added as the first filter (along with the decoder).
293
294 ---------------------------------------
295 0.4.1 (2009-12-22) "concurrent horizon"
296 ---------------------------------------
297
298 Support for another audio format, minor feature enhancements and lots of bug
299 fixes. All fixes that have been accumulated in the maint branch (in particular
300 those mentionened in the 0.3.6 release notes) appear in this release as well.
301
302 - wma support.
303 - new afh option: --human to activate human-readable output.
304 - new server/audiod option: --log-timing to print timing information.
305 - build system improvements.
306 - source code documentation updates.
307
308 -------------------------------------
309 0.3.6 (2009-12-07) "cubic continuity"
310 -------------------------------------
311
312 Quite a few bugs have been found and fixed since 0.3.5, so here's
313 another 0.3.x release. No new features.
314
315 - Always check return value of malloc().
316 - ogg vorbis/FEC: Do not write garbage after the audio file header.
317 - exit if root privileges could not be dropped.
318 - FEC: Fix computation of extra slices.
319 - oss: Fix check for empty input buffer.
320 - Avoid buffer underruns due to filter chain output buffer constraints.
321 - server: Fix assignment of afs_pid.
322 - Don't panic if the afs database contains unknown audio formats.
323 - http/dccp: Do not send the audio file header twice.
324 - FEC: Timing improvements.
325
326 ----------------------------------------------
327 0.4.0 (2009-11-10) "simultaneous independence"
328 ----------------------------------------------
329
330 Two significant changes which require the new version number: The
331 improved authentication dialog and the fact that the database code
332 has been moved to a library, libosl. To use the new version, you have
333 to generate new RSA keys, see INSTALL for details. A shell script is
334 provided for conversion of the 0.3 database to the new 0.4 format.
335
336 - stronger crypto for client authentication
337 - the database code has been moved to a library
338 - improved status item handling
339 - cleanup of the build system
340 - The "-V" option now also prints the git version
341 - the new parser-friendly listing mode for the ls and stat commands
342 - mandatory rc4 encryption
343 - major audio format handler cleanups
344 - (id3,...) tags are no longer stored as a combined string in the database
345 - new mood methods: artist_matches, title_matches, comment_matches,
346 album_matches, year_maches, year.
347
348 --------------------------------------------
349 0.3.5 (2009-09-21) "symplectic separability"
350 --------------------------------------------
351
352 Full client support for *BSD Unixes, complete re-write of the ogg
353 vorbis audio format handler, various improvements all over the place
354 and the usual mix of bugfixes. This release marks the end of the 0.3
355 series if no serious problems show up.
356
357 - the new oss writer (supported on *BSD and Linux)
358 - rewrite of the ogg vorbis audio format handler. It's
359 recommended to replace the chunk tables of existing ogg
360 vorbis files in the afs database by re-adding these files
361 with "add -f".
362 - support for netmask subsets (Gerrit Renker)
363 - the new prebuffer filter
364 - improved signal handling
365 - variable fec output buffer size
366 - improved FEC timing fixes audible buffer underruns in UDP mode
367 - --log_color actually works
368 - new ls option: -d (print dates as seconds after the epoch)
369 - update to gengetopt 2.22.2
370 - support for RSA keys of size > 512 bits
371 - new option "mixer_channel" for para_fade
372
373 -----------------------------------------
374 0.3.4 (2009-05-07) "elliptic inheritance"
375 -----------------------------------------
376
377 The new udp sender, forward error correction, colored logs and various
378 other improvements. As the udp sender does not depend on any special
379 libraries, it is built unconditionally.
380
381 - The udp sender replaces the ortp sender. The new code uses forward
382 error correction to protect against packet losses. Many thanks to
383 Gerrit Renker for providing ipv6 support.
384 - The default port for udp streaming now defaults to 8000, like
385 for the http and the dccp senders/receivers.
386 - Loglevels are now specified as symbolic names, e.g.
387 "--loglevel info".
388 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
389 - para_server/para_audiod: Color support for log messages.
390 - new options for mp3dec: --ignore-crc, --bufsize
391 - new audiod option: --config-file.
392 - gengetopt cleanups.
393 - Improved help/man pages: The documentation of para_audiod,
394 para_recv, para_filter and para_write now also contains
395 all options of the available receivers/filters/writers. The
396 man page of para_fade contains a description of the different
397 modes of operation.
398 - More source code documentation.
399 - vss timing fixes.
400
401 --------------------------------------------
402 0.3.3 (2008-12-01) "axiomatic perspectivity"
403 --------------------------------------------
404
405 Internal code cleanups, bug fixes, improved tag handling and the new
406 amplification filter.
407
408 - para_server uses the generic scheduling code.
409 - overhaul of the virtual streaming system.
410 - mp3: id3 version 2 support via libid3tag (optional)
411 - ogg: vorbis comment support.
412 - aac meta info support.
413 - mp3 audio format handler cleanups.
414 - new filter: "amp" to amplify the amplitude of the audio stream
415 - new status item/database entry: amplification. It is
416 used by the amp filter to pre-amplify the audio stream.
417 - fix a close-without-open bug in para_write.
418 - fix a bug in com_init() which was introduced in 0.3.2.
419 - better error diagnostics for para_client.
420
421 -----------------------------------------
422 0.3.2 (2008-04-11) "probabilistic parity"
423 -----------------------------------------
424
425 The new para_afh executable, scheduling and documentation improvements.
426
427 - new ls option: -lc (list chunk table)
428 - new executable: para_afh, the stand-alone audio file handler tool
429 - afs commands can send output more than SHMMAX (32MB on Linux). This
430 also reduces the memory usage of commands that produce large amounts
431 of output.
432 - major scheduler and audiod cleanups.
433 - more detailed and much nicer man pages.
434
435 ---------------------------------------
436 0.3.1 (2008-02-23) "liquid interaction"
437 ---------------------------------------
438
439 A mix of cleanups, bug fixes, improvements, and some new features. No
440 significant changes to the new database (osl) code, which is generally
441 a good sign.
442
443 - Share some similar/duplicate code between the http and the
444 dccp sender.
445 - Generic access control lists for paraslash senders.
446 - dccp sender: Access control lists, connection limiting and support
447 for the allow,deny,on,off,help sender commands.
448 - The default dccp port changed from 5001 to 8000 (suggested by
449 Gerrit Renker).
450 - para_server starts even if not all public keys could be loaded.
451 - Audiod performance improvements.
452 - fix a bug in the "off" command of the http sender.
453 - fix some fd and memory leaks.
454 - Update to gengetopt-2.22.
455
456 -------------------------------------
457 0.3.0 (2008-01-12) "solar saturation"
458 -------------------------------------
459
460 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
461
462
463 Usually one might expect lots of new features AND a big increase in size
464 for a major release like this.
465
466 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
467 ever. The decrease in size is mostly due to the removal of some
468 graphical tools (which were only quick hacks anyway). But also the
469 fact that the mysql code is gone cuts down the size a bit.
470
471 Being independent of mysql comes at a cost: The fact that paraslash
472 now contains its own database (the object storage layer, osl) increases
473 the (stripped) binary size of para_server by ~50K on i386.
474
475 - no more restrictions on unique basenames.
476 - independent of mysql: The new self-contained object
477 storage layer (osl) replaces the mysql database.
478 - New executable para_fsck: Check integrity of osl tables.
479 - Lyrics support.
480 - Reliable audio file move/rename detection.
481 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
482 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
483 Solaris (sparc64).
484 - the new osl-based audio file selector (afs) replaces the random,
485 the playlist and the mysql selector of paraslash-0.2.x.
486 - IPv6 support (thanks to Gerrit Renker).
487 - paraslash-0.2.x streams are now called "moods". Writing
488 0.3.x-mood definitions should be both easier and more
489 powerful than writing 0.2.x-stream definitions.
490 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
491 been removed. The world is a better place without them. However,
492 para_gui is still there.
493 - afs tracks audio file selection also in playlist mode.
494 - few easy-to-use afs commands replace the many not-so-easy-to-use
495 mysql commands (and are available also in playlist mode).
496 - Improved error subsystem.
497 - The earth-shaking new logo.
498
499 -----------------------------------------
500 0.2.17 (2007-11-20) "isotropic threshold"
501 -----------------------------------------
502
503 Mainly bugfixes and cleanups in this version which marks the end of
504 the 0.2.x series if no serious bugs show up after the release.
505
506 - mysql_selector: fix a locking bug.
507 - universal chunk queueing.
508 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
509 to Gerrit Renker).
510 - be more carful wrt. signed vs. unsigned argument passing.
511 - cleanup error.h and fix some references to invalid error
512 codes.
513 - update to gengetopt-2.21.
514 - update to ortp-0.13.1.
515 - autoconf: extend checks for headers, library functions and
516 compiler characteristics.
517 - Fix streaming of large mp3 files.
518 - Fix an off-by-one bug in playlist handling.
519
520 --------------------------------------
521 0.2.16 (2007-04-05) "neural discharge"
522 --------------------------------------
523
524 The main change in this release is the major audio format handler
525 cleanup which removes some similar/duplicate code and makes it easier
526 to implement plugins for other audio formats. Of course, the usual mix
527 of other improvements/changes/bugfixes also made it into the release.
528
529 - simplified audio format handlers (most of the handling functions
530 were moved one layer up to the virtual streaming system).
531 - para_server uses mmap to read audio files
532 - repositioning of mp3 streams is much faster, in particular for
533 jumping near the end of large mp3 files.
534 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
535 and AFS_WRITE.
536 - fix a bug in para_filter that caused decoding of aac files
537 to start only after a few seconds.
538 - fix osx_writer hangs
539 - simplified dccp code (thanks to Gerrit Renker)
540 - the compress filter works also on big endian systems (ppc)
541
542 -----------------------------------------
543 0.2.15 (2007-02-16) "inductive resonance"
544 -----------------------------------------
545
546 Minor improvements, more documentation and a bunch of bug fixes.
547
548 - para_server: The server.users file is only read once on server
549 startup rather than for each connection
550 - mp3dec: Fix decoding of corrupt mp3 files
551 - afs (audio file sender) is now called vss (virtual streaming
552 system). Consequently, the permission flags specified in
553 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
554 become VSS_READ and VSS_WRITE respectively.
555 - para_audiod/para_filter: Fix a bug that caused the last chunk
556 of audio data not being written under certain circumstances
557 - audiod: compute the difference of server time and local time
558 correctly
559 - para_server/para_audiod: Fix some memory leaks
560 - documentation improvements
561 - configure.ac: fix checks for para_krell
562 - new man pages
563
564 -------------------------------------------
565 0.2.14 (2006-10-15) "transient singularity"
566 -------------------------------------------
567
568 The only major enhancement of this version is the osx writer which completes
569 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
570 until now for reasons beyond the scope of this changelog entry.
571
572 - new output plugin for Mac Os: the osx writer
573 - rename configure command line options from --enable-xxx-headers to
574 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
575 - configure: new command line options: --with-mad-headers,
576 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
577 - some robustness fixes
578 - dymamic audio format recognition for audiod
579 - para_server: new command line option: --autoplay_delay
580 - para_audiod: new command line option: --clock_diff_count
581
582 ---------------------------------------
583 0.2.13 (2006-07-14) "sonic convolution"
584 ---------------------------------------
585
586 A bunch of new features and core changes.
587
588 - the new paraslash scheduler, short and sweet.
589 - Support for m4a/mp4 files via the new aac audio format
590 handler/filter (requires libfaad).
591 - each writer has its own command line parser, just like
592 para_recv and para_filter.
593 - para_client and para_audioc use the error subsystem
594 - writers are integrated in para_audiod (currently linux-only)
595 - para_client is integrated in para_audiod
596 - random/playlist selector: improved info strings
597 - new audiod commands: tasks, kill
598 - update to libortp-0.10.1
599 - para_fade: wake time defaults to 8 hours from now
600 - update to autoconf-2.60
601
602 ------------------------------------------
603 0.2.12 (2006-05-12) "oriented abstraction"
604 ------------------------------------------
605
606 Many user-visible changes in this release and lots of new
607 features:
608
609
610 - the new optional dccp sender/receiver. It uses the datagram
611 congestion control protocol. You'll need a fairly new kernel
612 for this.
613 - paraslash works on Mac OS X (thanks to Gerd Becker)
614 - para_play renamed to para_write
615 - modular output plugin design (writers) for para_write
616 - new file_writer output plugin for para_write
617 - compress filter speed improvements
618 - update to libortp-0.9.1
619 - update to gengetopt-2.17rc
620 - para_client no longer depends on libreadline (as the
621 code for the interactive mode was removed).
622 - gcc-2-95 is no longer a supported compiler. It may still
623 work, but it gets no more testing.
624 - the tarball no longer contains the screenshot images which
625 reduces its size quite a bit.
626 - configure: new command line options: --enable-mysql-headers
627 and --enable-mysql-libs
628
629 ------------------------------------
630 0.2.11 (2006-03-11) "atomic duality"
631 ------------------------------------
632
633 Here it is, the first paraslash release developed with git. There
634 are fairly many user-visible changes in this release. As two out of
635 the three "database tools" of paraslash don't use a database at all,
636 they are now called "audio file selectors" instead.
637
638
639 - the cdt command (change database tool) becomes chs (change
640 selector)
641 - no more colon separators: The syntax of some options of
642 para_audiod and para_filter have changed. Use --help for
643 more info (and some examples).
644 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
645 - switch from cvs to git (should've done that earlier)
646 - the new ipc subsystem
647 - new audio file selector: playlist
648 - para_server: the dopey selector is now called "random",
649 and is the default selector. Use the --selector option to
650 choose another selector at startup, or the chs command to
651 change the selector at runtime.
652 - X86_64 fixes (thanks to Steffen Klassert)
653 - para_play fixes
654
655 --------------------------------------
656 0.2.10 (2006-02-17) "cyclic attractor"
657 --------------------------------------
658
659 Huge documentation update, a scrollable window for para_gui, ortp
660 improvements, and of course many small fixes not mentioned here.
661 The diffstat below is rather misleading as most insertions are due
662 to the new source documentation.
663
664 - autoconf cleanup
665 - para_server also uses the new error subsystem
666 - lots of new documentation (UTSL)
667 - gui improvements:
668 - keysyms for cursor keys and for next/previous page keys
669 - scrollable output window
670 - new internal commands: scroll up/down, page up/down
671 - fix color of command output.
672 - ortp: the --chunk_time and --header flags are no longer needed
673 for para_recv/para_audiod as this information is now encoded in
674 each rtp packet sent by para_server.
675
676 -------------------------------------------
677 0.2.9 (2006-01-24) "progressive turbulence"
678 -------------------------------------------
679
680 Internal audiod receivers/filters, the new error subsystem and
681 a lot of small improvements.
682
683 - para_recv and para_filter are integrated into the para_audiod
684 binary, i.e. audiod no longer spawns a new process for
685 each receiver/filter. As para_recv and para_filter might be
686 useful as standalone programs, they still get built (linked
687 against the same object files that are also used for audiod).
688 - further ortp timing improvements should reduce the CPU usage
689 of the ortp receiver.
690 - improved audio grabbing. The 'grab' command of para_audiod
691 has its own set of command line options. Read the output of
692 "para_audioc help grab" for more info.
693 - oggdec: configurable input prebuffer size.
694 - the new error subsystem gives better error diagnostics
695 and reduces code size.
696
697 -----------------------------------------
698 0.2.8 (2006-01-02) "dynamic accumulation"
699 -----------------------------------------
700
701 The new modular filter design and the para_play-hangs bugfix.
702
703 - new executable: para_filter. It combines para_mp3dec,
704 para_oggdec and para_compress. It also adds a further filter
705 type, wav, that just inserts a wave header at the desired point
706 of the filter chain. All 'piping' is done in-memory (i.e. no
707 read/write operations are used).
708 - para_play: fix a stupid bug that caused it to hang under
709 certain circumstances.
710
711 -------------------------------------------
712 0.2.7 (2006-12-27) "transparent invariance"
713 -------------------------------------------
714
715 Not many user-visible changes but a fair amount of internal improvements.
716
717
718 - The http sender buffers data if it can not be sent
719 out immediately (because the socket is not writable). This
720 should prevent para_server from shutting down the connection
721 too early on a loaded network.
722 - para_play also prebuffers data if it is told to start at a
723 future time by the --start_time option.
724 - The return of para_recv: It combines para_ortp_recv and
725 para_http_recv. Use the --receiver option to switch between
726 the two. para_recv builds without libortp, but contains
727 only the http receiver in this case.
728 - update to ortp 0.8.1. As this ortp release contains incompatible
729 changes, para_recv-0.2.7 won't link against older ortp libs.
730 - improved ortp timings.
731 - use of gcc-extensions that #define away for non-gcc and
732 gcc < 3.0.
733
734 -------------------------------------------
735 0.2.6 (2005-10-29) "recursive compensation"
736 -------------------------------------------
737
738 Transparent session encryption (uses openssl's Alleged RC4 cipher),
739 the internal find command and several other improvements and cleanups.
740
741 - Encrypt the session if encryption is requested by the client
742 (default for para_client 0.2.6). This is backwards
743 compatible, so older clients can still connect to para_server
744 0.2.6. Use the new client option --plain to request an
745 uncrypted session (off by default, must be set to on in
746 order to connect to para_server 0.2.x with 0 <= x <= 5).
747 - para_server uses an internal function to locate audio files
748 rather than calling find(1). The server option
749 --mysql_audio_file_dir replaces --mysql_find_cmd.
750 - documentation update
751 - man pages
752 - header file cleanup
753 - para_client code cleanup
754 - para_gui: faster display of output of display commands
755
756 ------------------------------------------
757 0.2.5 (2005-10-13) "aggressive resolution"
758 ------------------------------------------
759
760 This release adds internal senders, i.e. no more external programs are
761 spawned for sending out the audio data. There are two different senders
762 available: The http sender and the ortp sender (former para_send which
763 is no longer needed).
764
765 The new sender code has a plugin-like design so it can be easily
766 extended should there be be any future need for supporting another
767 network streaming protocol. All senders are completely independent of
768 each other. In particular, the http and the ortp sender can operate
769 in parallel.
770
771 - new server command: sender to control senders at runtime.
772 Read the output of "para_server -h" and "para_client help
773 sender" for more information.
774 - para_recv renamed to para_ortp_recv
775 - new executable: para_http_recv, a simple command line
776 http receiver.
777 - major afs/mp3/ogg code simplifications due to internal
778 senders.
779 - ogg timing improvements
780 - fix several minor memory leaks (found by valgrind)
781 - empty stream definitions work again
782 - com_ne(): ignore errors on remove
783 - audiod: fix segfault on server restart
784
785 ---------------------------------------
786 0.2.4 (2005-09-21) "toxic anticipation"
787 ---------------------------------------
788
789 Several small improvements, fixes and the new grab command.
790
791 - audiod:
792 - new command: "grab" to grab the output of the stream reader
793 or any filters. Read the output of "para_audioc help grab"
794 for more information.
795 - fix memory leak
796 - code cleanup
797 - audioc: new command line option: --bufsize to specify a
798 buffer size different from the default size 8192.
799 - improved error diagnostics for para_play.
800 - new configure option: --enable-ssldir so search for openssl in
801 non-standard places
802 - sdl_gui: Make it look nice again for 1024x768
803 - server: report total size of memory allocated with sbrk by malloc,
804 new command line option: --announce_time
805
806 -----------------------------------------
807 0.2.3 (2005-09-01) "hydrophilic movement"
808 -----------------------------------------
809
810 Two new executables and major feature enhancements.
811
812 - audiod filters: It is now possible to specify arbitrary many
813 (including none) filters for each supported audio
814 format. This can be used e.g. for normalizing volume,
815 transforming or grabbing the audio stream, or for using
816 visualizers. Read the output of "para_audiod -h" for the
817 syntax of the new --filter_cmd option.
818 - new executable: para_play, a tiny alsa player. It
819 can play wave files or raw pcm (16 bit little endian)
820 from stdin.
821 - new executable: para_compress, a dynamic range compressor
822 intended to keep audio output at a consistent volume. Derived
823 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
824 - audiod: New option: --stream_delay. This can be used in
825 a local network to syncronize the audio output of all
826 clients that play the same stream.
827
828 ------------------------------------------
829 0.2.2 (2005-08-19) "tangential excitation"
830 ------------------------------------------
831
832 Mostly internal changes in this release, but also some new commands
833 for the mysql database tool.
834
835 - cleanup exec.c, fix para_exec bug
836 - compile time loglevel (log messages below the given level
837 won't be compiled in, which reduces the size of the
838 resulting binaries)
839 - new log macros that shorten the size of the source code.
840 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
841 to send only zeros. With this workaround, para_audioc works
842 again.
843 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
844 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
845 (new entry), "snp" (set numplayed). Read the manual for more
846 information.
847
848 ---------------------------------------
849 0.2.1 (2005-08-15) "surreal experience"
850 ---------------------------------------
851
852 Here comes paraslash-0.2.1. It contains a couple of new features and,
853 surprise, only minor bug fixes.
854
855 - kill noisy mp3 debug message
856 - cleanup of the build system
857 - para_server and para_client directly use the crypto routines
858 of the openssl library rather than invoking the openssl command
859 line utitlity
860 - server/audiod: new option --user to switch to the given user
861 when invoked as root. Read the output of "para_server -h" for
862 more information.
863 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
864 status. Default: "para_audioc stat"
865 - sdl_gui: new option --pic_cmd to be used to download the picture.
866 Default: "para_client pic"
867 - audiod: 5 slots ought to be enough for everybody
868 - audiod: new status item: Uptime, kill hup command
869
870 ------------------------------------------
871 0.2.0 (2005-08-06) "distributed diffusion"
872 ------------------------------------------
873
874 After several month of increased development activity, paraslash-0.2.0
875 has arrived. It contains many new features and is much more
876 self-contained than the old 0.1.x series. Enjoy!
877
878
879 - para_server: fix hang on song change and crash on sighup.
880 Speed up mysql queries. The DIR_LIKE macro is gone.
881 - new executables: para_audiod, the local audio daemon that
882 starts playback (uses SCM_CREDENTIALS socket magic) and
883 para_audioc, the corresponding client.
884 - new executables: para_mp3dec/para_oggdec, two really teensy
885 decoders. para_mp3dec is based on libmad, para_oggdec requires
886 libvorbisfile.
887 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
888 they are now called para_send and para_recv respectively.
889 - documentation updates
890 - para_gui is themable. For now there is the default theme that
891 looks as before and the simple theme: blue and easy.
892 - gui: audio streaming is now handled by audiod. Time display shows
893 playback time rather than streaming time
894 - slider: update to libzmw-0.2.0
895 - para_krell: fix crash on server shutdown
896 - switch from gzip to bzip2
897
898 ----------------------------------------
899 0.1.7 (2005-04-18) "melting penetration"
900 ----------------------------------------
901
902 The main change in this release is clearly the oggvorbis rewrite,
903 but there are also lots of smaller changes. If you intend to use both
904 the mp3 and the ogg plugin, it is recommended to use software mixing,
905 e.g. the dmix plugin which is provided by ALSA.
906
907 - new executables: para_ovsend and para_ovrecv for sending/receiving
908 oggvorbis files via rtp. Requires the open rtp library. Get it at
909 http://www.linphone.org/ortp/
910 - rewrite of the ogg_vorbis core code
911 - configure detects libzmw and, if detected, includes
912 para_slider to the list of binaries to be built by make
913 - server stream writers read from their associated fifo rather
914 than from stdin
915 - slider: two new sliders, lastplayed and numplayed
916 - fix nasty double free bug which caused random segfaults in case of
917 mp3 files with invalid header information
918 - gui: new command line option: --stream_timeout=seconds to
919 deactivate a slot if it is idle for that many seconds (default=`5')
920 - diffstats
921
922 ---------------------------------------
923 0.1.6 (2005-03-05) "asymptotic balance"
924 ---------------------------------------
925
926 Only little user-visible changes in this release. Mainly bugfixes and
927 core code cleanup. This is probably the most stable version ever if you
928 stick to mp3...
929
930 - fix several memory leaks
931 - rename default name of mysql database from "music" to "paraslash".
932 Use para_server's --mysql_database option if you do not want to
933 rename your old database.
934 - rework ogg vorbis code
935 - make update command work on mysql servers with LOCAL_INFILE
936 disabled
937 - gui: improved stream I/O (slots)
938 - simplified audio format API
939 - para_pob_ogg is gone
940
941 ------------------------------------
942 0.1.5 (2004-12-31) "opaque eternity"
943 ------------------------------------
944
945 Let's slide gently into the new year.
946
947 - new: para_slider (not built automatically, type "make
948 para_slider" to build). A toy for those who always felt that
949 creating stream definitions is difficult. See screenshots,
950 README and FEATURES for more info.
951 - improved signal handling. Fixes server segfault on SIGHUP
952 for linux kernels newer than Aug 24 2004 and makes para_gui
953 race-free.
954 - reload database tool on SIGHUP
955 - improved help message for sl
956 - do not log "broken pipe" messages as errors. They are
957 perfectly ok.
958 - fix wrong error message on permission errors
959
960 -----------------------------------------
961 0.1.4 (2004-12-19) "tunneling transition"
962 -----------------------------------------
963
964 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
965 Hopefully, most of them got wiped out with this release. Some
966 enhancements went also in.
967
968 - improved error diagnostics for all commands
969 - stradd/picadd: overwrite previous contents if entry already
970 exists, rather than returning errors
971 - stradd: use current stream if invoked without args
972 - faster (and hopefully more stable) ogg-vorbis handling
973 - para_krell: reap children to avoid zombie-flooding in case
974 no server is running
975 - si: report also server pid
976 - server: don't busy-loop if dbtool reports only invalid files.
977 - gui: CTRL+C works again, fix stream_read command line option
978 - fix pic_add, hist
979 - fix mysql dbtool startup in case no database exists
980 - many small fixes and cleanups
981
982 ---------------------------------------
983 0.1.3: (2004-12-10) "vanishing inertia"
984 ---------------------------------------
985
986 Starting from this release, the database tools are integrated in the
987 server binary. This decreases server startup time, reduces code size
988 and speeds up database commands. However, the layout of the underlying
989 mysql database changed only slightly and 0.1.3 should be backwards
990 compatible in that respect.
991
992 Visible changes:
993
994 - If mysql is not detected at compile time, or fails to init
995 at runtime, fall back to the dopey database tool which should
996 always work.
997 - para_dbtool and dbtool.conf are gone. All mysql specific
998 options are read from server.conf and are prefixed by 'mysql_'.
999 - new command: cdt (change database tool)
1000 - new command line option: dbtool (choose startup database tool)
1001 - The name of current stream is now stored in the database,
1002 so paraslash remembers its current stream when restarted.
1003 - new command: csp (change stream and play)
1004 - para_gui also reports current database tool and server uptime
1005
1006 -------------------------------------------
1007 0.1.2: (2004-11-28) "spherical fluctuation"
1008 -------------------------------------------
1009
1010 Point release before the big dbtool changes go in.
1011
1012 - dbtool: rename ca to cam (copy all meta data). It now also
1013 copies numplayed and lastplayed time as well as the picture
1014 id.
1015 - fix endless-loop-bug caused by mp3 files with invalid header
1016
1017 -----------------------------------------
1018 0.1.1: (2004-11-05) "floating atmosphere"
1019 -----------------------------------------
1020
1021 - gkrellm plugin
1022 - new dbtool command: mbox. Browse your sound-file collection
1023 with your favorite mail reader.
1024 - several small fixes
1025
1026 -------------------------------------
1027 0.1.0: (2004-10-22) "rotating cortex"
1028 -------------------------------------
1029
1030 - fix logging bug for loglevel > VERBOSE
1031 - fix skip command
1032 - correct timings for vbr mp3s
1033 - modular audio format support
1034 - ogg-vorbis support (experimental)
1035 - new server option: autoplay
1036
1037 -----------------------------------------
1038 0.0.99: (2004-07-25) "harmonic deviation"
1039 -----------------------------------------
1040
1041 - rename projectname from icc to paraslash (play, archive, rate
1042 and stream large audio sets happily)
1043 - paraslash is no longer restricted to one particular audio
1044 streaming software
1045 - new dbtool commands (stradd, strq, strdel) for easy stream
1046 managment w/o configuration file. That obsoletes stream_defs
1047 file/config option for dbtool.
1048 - picadd accepts jpeg data from stdin
1049 - new server commands: ps (select previous stream), sc (song change)
1050 - new default pictures for sdl_gui
1051 - gui: new key_map option for binding commands and internal
