4 --------------------------------------------
5 Noteworthy changes recently merged to master
6 --------------------------------------------
7
8 - The sideband compatibility code has been removed, hence
9 sideband connections (introduced in 0.4.11) are now mandatory.
10 - Addblob commands can produce output.
11 - The stat command no longer sends garbage when para_server was
12 compiled against libgcrypt.
13 - Dependencies for gengetopt files are computed automatically.
14 This eliminates a constant source of build bugs.
15 - The setatt command now accepts file name patterns rather than only
16 path names.
17 - overview.pdf is now based on dia, a simple diagram creation program.
18 The new version is much more detailed and contains descriptions of
19 the various programs of the paraslash package.
20 - The separator of all multi-word options has been changed from
21 underscore to dash. For example --log_color becomes --log-color.
22 - Overhauled web pages and the new logo.
23
24 --------------------------------------
25 0.4.13 (2013-07-29) "spectral gravity"
26 --------------------------------------
27
28 One more 0.4.x release before the API-breaking changes for 0.5.0 go
29 in. The main features of this release are the ogg/opus audio format,
30 and UTF-8 support, but it includes also tons of other improvements
31 and fixes all over the place.
32
33 - New audio format: ogg/opus.
34 - UTF8 support for para_gui and the mp3 audio format handler.
35 - Scheduler improvements and fixes.
36 - The obsolete gettimeofday() function has been replaced
37 by clock_gettime() on systems which support it.
38 - Speed and usability improvements for para_gui.
39 - para_client now restores the fd flags of stdin and stdout
40 on shutdown.
41 - Improved manual pages.
42 - Consistent version strings for all executables.
43 - Reduced dependencies on generated files result in fewer
44 recompilations on changes.
45 - Performance improvements for the compress filter.
46 - Improved downloads web page.

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