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

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