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

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