[paraslash.git] / NEWS
1 ---------------------------------------------
2 0.5.0 (to be announced) "invertible validity"
3 ---------------------------------------------
4
5 - The sideband compatibility code has been removed, hence
6 sideband connections (introduced in 0.4.11) are now mandatory.
7 - Addblob commands can produce output.
8 - The stat command no longer sends garbage when para_server was
9 compiled against libgcrypt.
10 - Dependencies for gengetopt files are computed automatically.
11 This eliminates a constant source of build bugs.
12 - The setatt command now accepts file name patterns rather than only
13 path names.
14
15 --------------------------------------
16 0.4.13 (2013-07-29) "spectral gravity"
17 --------------------------------------
18
19 One more 0.4.x release before the API-breaking changes for 0.5.0 go
20 in. The main features of this release are the ogg/opus audio format,
21 and UTF-8 support, but it includes also tons of other improvements
22 and fixes all over the place.
23
24 - New audio format: ogg/opus.
25 - UTF8 support for para_gui and the mp3 audio format handler.
26 - Scheduler improvements and fixes.
27 - The obsolete gettimeofday() function has been replaced
28 by clock_gettime() on systems which support it.
29 - Speed and usability improvements for para_gui.
30 - para_client now restores the fd flags of stdin and stdout
31 on shutdown.
32 - Improved manual pages.
33 - Consistent version strings for all executables.
34 - Reduced dependencies on generated files result in fewer
35 recompilations on changes.
36 - Performance improvements for the compress filter.
37 - Improved downloads web page.
38
39 -----------------------------------------
40 0.4.12 (2012-12-20) "volatile relativity"
41 -----------------------------------------
42 The new command line player, the resample filter, ALSA support for
43 para_fade, and the improved build system are the highlights of this
44 release which probably marks the end of the 0.4.x series.
45
46 - The afh receiver and the para_play executable.
47 - The resample filter: A sample rate converter based on
48 libsamplerate.
49 - The "versions" directory has been removed from the master
50 branch. The tarballs of the old releases are now available
51 in the new "releases" branch.
52 - Overhaul of the build system: All generated files are now
53 written to the "build" directory.
54 - The modular mixer API and the alsa mixer.
55 - Minor fixes for the osx writer.
56
57 --------------------------------------
58 0.4.11 (2012-07-20) "mutual diversity"
59 --------------------------------------
60
61 The major feature in this release is the new sideband API for
62 client-server communication. This API will be used exclusively starting
63 with 0.5.0, which breaks backward compatibility but allows to get rid
64 of quite some compatibility code. Other noteworthy changes include
65 decoder latency improvements and a long-standing bug fix for the
66 ALSA writer.
67
68 - Sideband connections: If both para_server and para_client
69 support this feature, data is sent as a multiplexed stream.
70 - The --no_default_filters option of para_filter has been
71 removed.
72 - Several fixes and latency improvements to various decoders.
73 - The ALSA writer now limits the prebuffer time to 500ms.
74 - Documentation improvements.
75 - Overhaul of the command_util.sh script.
76 - Fixes for some minor problems found by the clang analyzer.
77 - Compiles (almost) without warnings on gcc-3.
78 - Robustness improvements of the buffer tree code.
79
80 ------------------------------------------
81 0.4.10 (2012-03-30) "heterogeneous vacuum"
82 ------------------------------------------
83
84 Nothing earth-shaking in this release, but quite a few usability
85 improvements and the usual mix of cleanups and fixes.
86
87 - The --no_default_filters option of para_filter has been
88 deprecated. It still works but has no effect and will be
89 removed in the next version.
90 - para_gui now prints also the stderr output of the executing
91 command in the bottom window.
92 - Cleanup and consolidation of the various wrappers for
93 write(), writev(), send() and friends.
94 - The obscure error messages on mmap() failures have been
95 replaced by meaningful messages. This affects mainly
96 para_afh.
97 - para_audioc: Cleanups and memory leak fixes.
98 - Test 0004-server no longer fails if para_server is not
99 being built.
100 - New configure options: --with-id3tag-{headers,libs}.
101
102 -------------------------------------
103 0.4.9 (2011-12-06) "hybrid causality"
104 -------------------------------------
105
106 Support for another audio format, interactive mode for para_client
107 and para_audiod and many small improvements/fixes all over the place.
108
109 - Support for flac, the free lossless audio codec.
110 - Fix for an endless loop in the mp3 decoder for certain
111 (corrupt) mp3 files.
112 - When executed without specifying a command, para_client
113 and para_audioc start an interactive shell (requires
114 libreadline being installed). The interactive mode offers
115 full tab completion and command line history.
116 - autogen.sh now detects a distcc setup and adjusts the
117 parameter for the -j option of make accordingly.
118 - Shared memory areas are no longer restricted to 64K. We now
119 detect the maximal size of a shared memory area at runtime.
120 - cleanup of the internal uptime API.
121 - para_server prefaults the mmapped audio file to avoid
122 delays on slow media.
123 - A new test for the test-suite that exercises the
124 communication between para_server and para_audiod.
125 - The alsa writer eats up less CPU cycles when configured to
126 use the DMIX plugin.
127 - Simplified and unified receiver code.
128 - Makefile cleanups.
129 - Commands which print a list of matching audio files now
130 emit a meaningful error message if no audio file matched the
131 given pattern(s).
132
133 --------------------------------------
134 0.4.8 (2011-08-19) "nested assignment"
135 --------------------------------------
136
137 Gcrypt support, the overhauled osx writer and regex format specifiers
138 are the highlights of this release.
139
140 - support for libgcrypt as a drop-in replacement for openssl.
141 Run configure --enable-cryptolib=gcrypt to link against
142 libgcrypt. The two crypto implementations are compatible to
143 each other, i.e. a para_client executable linked against
144 gcrypt can connect to para_server linked against libssl
145 and vice versa.
146 - Rewrite of the osx writer (output plugin for Mac OS).
147 - audiod: The format specifier for receivers, filters and
148 writers is now treated as a regular expression. This allows
149 to replace 5 lines in the config file (one for each audio
150 format) by one single line. See the manual for details.
151 - The *.cmdline.[ch] files are no longer contained in the released
152 tarballs. This reduces the size of the tarballs but requires
153 gengetopt to build the tarball.
154 - Compiles cleanly also with llvm/clang.
155 - Corrupt mp3 files are handled more gracefully.
156 - The alsa writer uses poll fds instead of computing timeouts.
157 - Cleanup of the generic writer API.
158 - sched: Optimized zero timeouts.
159 - vss timeout cleanups.
160 - oggdec fixes and improvements.
161
162 --------------------------------------
163 0.4.7 (2011-06-01) "infinite rollback"
164 --------------------------------------
165
166 The new ao writer, support for ssh RSA keys and a couple of other
167 enhancements.
168
169 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
170 platforms through the libao audio library.
171 - Support for RSA keys generated with ssh-keygen.
172 - configure: improved options for ogg/vorbis/speex.
173 - The git version reported by --version always matches HEAD.
174 - The autogen script detects the number of processors and
175 runs a parallel make if possible.
176 - Major cleanup of the crypto API.
177 - Documentation updates.
178
179 ------------------------------------------
180 0.4.6 (2011-03-31) "deterministic entropy"
181 ------------------------------------------
182
183 Lots of ogg/vorbis improvements, the new test suite, enhancements
184 for para_gui and a fair amount of other bug fixes.
185
186 - For DCCP/OGG streams the audio file header is only sent once
187 at the beginning of the stream rather than periodically
188 every five seconds. This reduces network traffic and the
189 FEC group size.
190 - The vorbis comment header is replaced by an empty dummy header
191 before the header is sent over the network. This also results in
192 less network traffic and smaller FEC groups.
193 - The new "test" make target allows to perform some sanity checks prior
194 to installing the package.
195 - ogg timing fixes and performance improvements
196 - Scheduler improvements
197 - Proper exit codes for para_write
198 - para_gui: New option --theme to select a startup theme. Several
199 other improvements and fixes.
200 - aacdec error message cleanups
201 - simplified color error handling
202
203 --------------------------------------------
204 0.4.5 (2010-12-17) "symmetric randomization"
205 --------------------------------------------
206
207 Bug fixes, internal cleanups and variable-sized FEC slices.
208
209 - Contains a fix for an invalid-free-bug in the ogg audio format
210 handler code.
211 - Switching off the DCCP sender works again.
212 - para_audiod handles crashes of para_server more robustly.
213 - Internal scheduler and writer cleanups.
214 - Reduced latency due to variable-sized FEC slices.
215 - Improved documentation and error diagnostics.
216 - The build of para_server is now optional, allowing the build
217 to succeed in case libosl is not installed.
218
219 ------------------------------------------
220 0.4.4 (2010-08-06) "persistent regularity"
221 ------------------------------------------
222
223 Support for yet another audio format, para_write improvements and
224 bug fixes.
225
226 - Support for the speex codec.
227 - Support for sample formats other than 16 bit little endian.
228 - error2.h is now created by a perl script which speeds up configure
229 considerably.
230 - Fix a bug in the aac decoder which could lead to segfaults in
231 para_filter/para_audiod.
232 - Fixes for autoconf-2.66.
233
234 ----------------------------------------
235 0.4.3 (2010-07-05) "imaginary radiation"
236 ----------------------------------------
237
238 Many improvements for the DCCP and the UDP transport, the new user
239 manual and the usual mix of bug fixes and internal improvements.
240
241 - FEC support for the DCCP sender (Gerrit Renker). The new
242 --dccp_max_slice_size, --dccp_data_slices_per_group and
243 --dccp_slices_per_group options can be used to set the FEC
244 parameters for the DCCP transport.
245 - DNS lookups for UDP targets (Gerrit Renker).
246 - The new user manual replaces the README, README.afs, REQUIREMENTS
247 and INSTALL documents.
248 - Fix an end-of-file detection bug in the oggdec filter.
249 - The new nonblock API.
250 - Both options of the oggdec filter have been removed.
251 - New debug mode for the internal scheduler.
252
253 ------------------------------------------
254 0.4.2 (2010-04-23) "associative expansion"
255 ------------------------------------------
256
257 It's been some time since the last release, but finally here is
258 paraslash-0.4.2. The bulk of the changes comes from the new buffer
259 tree API, but there are changes all over the tree. Mainly performance
260 and usability improvements, but also quite some bug fixes.
261
262 - The new buffer tree API.
263 - DCCP: Support for CCID negotiation (Gerrit Renker).
264 - UDP robustness fixes.
265 - The --bufsize option for mp3dec is gone as it no longer makes sense
266 for the new buffer tree API.
267 - Fix audible buffer underruns for wma streams.
268 - The alsa writer no longer prints meaningless underrun durations.
269 - audiod: Defaults work also for udp streams. If no filter is
270 given for an audio format that is received via upd, fecdec is
271 automatically added as the first filter (along with the decoder).
272
273 ---------------------------------------
274 0.4.1 (2009-12-22) "concurrent horizon"
275 ---------------------------------------
276
277 Support for another audio format, minor feature enhancements and lots of bug
278 fixes. All fixes that have been accumulated in the maint branch (in particular
279 those mentionened in the 0.3.6 release notes) appear in this release as well.
280
281 - wma support.
282 - new afh option: --human to activate human-readable output.
283 - new server/audiod option: --log-timing to print timing information.
284 - build system improvements.
285 - source code documentation updates.
286
287 -------------------------------------
288 0.3.6 (2009-12-07) "cubic continuity"
289 -------------------------------------
290
291 Quite a few bugs have been found and fixed since 0.3.5, so here's
292 another 0.3.x release. No new features.
293
294 - Always check return value of malloc().
295 - ogg vorbis/FEC: Do not write garbage after the audio file header.
296 - exit if root privileges could not be dropped.
297 - FEC: Fix computation of extra slices.
298 - oss: Fix check for empty input buffer.
299 - Avoid buffer underruns due to filter chain output buffer constraints.
300 - server: Fix assignment of afs_pid.
301 - Don't panic if the afs database contains unknown audio formats.
302 - http/dccp: Do not send the audio file header twice.
303 - FEC: Timing improvements.
304
305 ----------------------------------------------
306 0.4.0 (2009-11-10) "simultaneous independence"
307 ----------------------------------------------
308
309 Two significant changes which require the new version number: The
310 improved authentication dialog and the fact that the database code
311 has been moved to a library, libosl. To use the new version, you have
312 to generate new RSA keys, see INSTALL for details. A shell script is
313 provided for conversion of the 0.3 database to the new 0.4 format.
314
315 - stronger crypto for client authentication
316 - the database code has been moved to a library
317 - improved status item handling
318 - cleanup of the build system
319 - The "-V" option now also prints the git version
320 - the new parser-friendly listing mode for the ls and stat commands
321 - mandatory rc4 encryption
322 - major audio format handler cleanups
323 - (id3,...) tags are no longer stored as a combined string in the database
324 - new mood methods: artist_matches, title_matches, comment_matches,
325 album_matches, year_maches, year.
326
327 --------------------------------------------
328 0.3.5 (2009-09-21) "symplectic separability"
329 --------------------------------------------
330
331 Full client support for *BSD Unixes, complete re-write of the ogg
332 vorbis audio format handler, various improvements all over the place
333 and the usual mix of bugfixes. This release marks the end of the 0.3
334 series if no serious problems show up.
335
336 - the new oss writer (supported on *BSD and Linux)
337 - rewrite of the ogg vorbis audio format handler. It's
338 recommended to replace the chunk tables of existing ogg
339 vorbis files in the afs database by re-adding these files
340 with "add -f".
341 - support for netmask subsets (Gerrit Renker)
342 - the new prebuffer filter
343 - improved signal handling
344 - variable fec output buffer size
345 - improved FEC timing fixes audible buffer underruns in UDP mode
346 - --log_color actually works
347 - new ls option: -d (print dates as seconds after the epoch)
348 - update to gengetopt 2.22.2
349 - support for RSA keys of size > 512 bits
350 - new option "mixer_channel" for para_fade
351
352 -----------------------------------------
353 0.3.4 (2009-05-07) "elliptic inheritance"
354 -----------------------------------------
355
356 The new udp sender, forward error correction, colored logs and various
357 other improvements. As the udp sender does not depend on any special
358 libraries, it is built unconditionally.
359
360 - The udp sender replaces the ortp sender. The new code uses forward
361 error correction to protect against packet losses. Many thanks to
362 Gerrit Renker for providing ipv6 support.
363 - The default port for udp streaming now defaults to 8000, like
364 for the http and the dccp senders/receivers.
365 - Loglevels are now specified as symbolic names, e.g.
366 "--loglevel info".
367 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
368 - para_server/para_audiod: Color support for log messages.
369 - new options for mp3dec: --ignore-crc, --bufsize
370 - new audiod option: --config-file.
371 - gengetopt cleanups.
372 - Improved help/man pages: The documentation of para_audiod,
373 para_recv, para_filter and para_write now also contains
374 all options of the available receivers/filters/writers. The
375 man page of para_fade contains a description of the different
376 modes of operation.
377 - More source code documentation.
378 - vss timing fixes.
379
380 --------------------------------------------
381 0.3.3 (2008-12-01) "axiomatic perspectivity"
382 --------------------------------------------
383
384 Internal code cleanups, bug fixes, improved tag handling and the new
385 amplification filter.
386
387 - para_server uses the generic scheduling code.
388 - overhaul of the virtual streaming system.
389 - mp3: id3 version 2 support via libid3tag (optional)
390 - ogg: vorbis comment support.
391 - aac meta info support.
392 - mp3 audio format handler cleanups.
393 - new filter: "amp" to amplify the amplitude of the audio stream
394 - new status item/database entry: amplification. It is
395 used by the amp filter to pre-amplify the audio stream.
396 - fix a close-without-open bug in para_write.
397 - fix a bug in com_init() which was introduced in 0.3.2.
398 - better error diagnostics for para_client.
399
400 -----------------------------------------
401 0.3.2 (2008-04-11) "probabilistic parity"
402 -----------------------------------------
403
404 The new para_afh executable, scheduling and documentation improvements.
405
406 - new ls option: -lc (list chunk table)
407 - new executable: para_afh, the stand-alone audio file handler tool
408 - afs commands can send output more than SHMMAX (32MB on Linux). This
409 also reduces the memory usage of commands that produce large amounts
410 of output.
411 - major scheduler and audiod cleanups.
412 - more detailed and much nicer man pages.
413
414 ---------------------------------------
415 0.3.1 (2008-02-23) "liquid interaction"
416 ---------------------------------------
417
418 A mix of cleanups, bug fixes, improvements, and some new features. No
419 significant changes to the new database (osl) code, which is generally
420 a good sign.
421
422 - Share some similar/duplicate code between the http and the
423 dccp sender.
424 - Generic access control lists for paraslash senders.
425 - dccp sender: Access control lists, connection limiting and support
426 for the allow,deny,on,off,help sender commands.
427 - The default dccp port changed from 5001 to 8000 (suggested by
428 Gerrit Renker).
429 - para_server starts even if not all public keys could be loaded.
430 - Audiod performance improvements.
431 - fix a bug in the "off" command of the http sender.
432 - fix some fd and memory leaks.
433 - Update to gengetopt-2.22.
434
435 -------------------------------------
436 0.3.0 (2008-01-12) "solar saturation"
437 -------------------------------------
438
439 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
440
441
442 Usually one might expect lots of new features AND a big increase in size
443 for a major release like this.
444
445 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
446 ever. The decrease in size is mostly due to the removal of some
447 graphical tools (which were only quick hacks anyway). But also the
448 fact that the mysql code is gone cuts down the size a bit.
449
450 Being independent of mysql comes at a cost: The fact that paraslash
451 now contains its own database (the object storage layer, osl) increases
452 the (stripped) binary size of para_server by ~50K on i386.
453
454 - no more restrictions on unique basenames.
455 - independent of mysql: The new self-contained object
456 storage layer (osl) replaces the mysql database.
457 - New executable para_fsck: Check integrity of osl tables.
458 - Lyrics support.
459 - Reliable audio file move/rename detection.
460 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
461 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
462 Solaris (sparc64).
463 - the new osl-based audio file selector (afs) replaces the random,
464 the playlist and the mysql selector of paraslash-0.2.x.
465 - IPv6 support (thanks to Gerrit Renker).
466 - paraslash-0.2.x streams are now called "moods". Writing
467 0.3.x-mood definitions should be both easier and more
468 powerful than writing 0.2.x-stream definitions.
469 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
470 been removed. The world is a better place without them. However,
471 para_gui is still there.
472 - afs tracks audio file selection also in playlist mode.
473 - few easy-to-use afs commands replace the many not-so-easy-to-use
474 mysql commands (and are available also in playlist mode).
475 - Improved error subsystem.
476 - The earth-shaking new logo.
477
478 -----------------------------------------
479 0.2.17 (2007-11-20) "isotropic threshold"
480 -----------------------------------------
481
482 Mainly bugfixes and cleanups in this version which marks the end of
483 the 0.2.x series if no serious bugs show up after the release.
484
485 - mysql_selector: fix a locking bug.
486 - universal chunk queueing.
487 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
488 to Gerrit Renker).
489 - be more carful wrt. signed vs. unsigned argument passing.
490 - cleanup error.h and fix some references to invalid error
491 codes.
492 - update to gengetopt-2.21.
493 - update to ortp-0.13.1.
494 - autoconf: extend checks for headers, library functions and
495 compiler characteristics.
496 - Fix streaming of large mp3 files.
497 - Fix an off-by-one bug in playlist handling.
498
499 --------------------------------------
500 0.2.16 (2007-04-05) "neural discharge"
501 --------------------------------------
502
503 The main change in this release is the major audio format handler
504 cleanup which removes some similar/duplicate code and makes it easier
505 to implement plugins for other audio formats. Of course, the usual mix
506 of other improvements/changes/bugfixes also made it into the release.
507
508 - simplified audio format handlers (most of the handling functions
509 were moved one layer up to the virtual streaming system).
510 - para_server uses mmap to read audio files
511 - repositioning of mp3 streams is much faster, in particular for
512 jumping near the end of large mp3 files.
513 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
514 and AFS_WRITE.
515 - fix a bug in para_filter that caused decoding of aac files
516 to start only after a few seconds.
517 - fix osx_writer hangs
518 - simplified dccp code (thanks to Gerrit Renker)
519 - the compress filter works also on big endian systems (ppc)
520
521 -----------------------------------------
522 0.2.15 (2007-02-16) "inductive resonance"
523 -----------------------------------------
524
525 Minor improvements, more documentation and a bunch of bug fixes.
526
527 - para_server: The server.users file is only read once on server
528 startup rather than for each connection
529 - mp3dec: Fix decoding of corrupt mp3 files
530 - afs (audio file sender) is now called vss (virtual streaming
531 system). Consequently, the permission flags specified in
532 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
533 become VSS_READ and VSS_WRITE respectively.
534 - para_audiod/para_filter: Fix a bug that caused the last chunk
535 of audio data not being written under certain circumstances
536 - audiod: compute the difference of server time and local time
537 correctly
538 - para_server/para_audiod: Fix some memory leaks
539 - documentation improvements
540 - configure.ac: fix checks for para_krell
541 - new man pages
542
543 -------------------------------------------
544 0.2.14 (2006-10-15) "transient singularity"
545 -------------------------------------------
546
547 The only major enhancement of this version is the osx writer which completes
548 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
549 until now for reasons beyond the scope of this changelog entry.
550
551 - new output plugin for Mac Os: the osx writer
552 - rename configure command line options from --enable-xxx-headers to
553 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
554 - configure: new command line options: --with-mad-headers,
555 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
556 - some robustness fixes
557 - dymamic audio format recognition for audiod
558 - para_server: new command line option: --autoplay_delay
559 - para_audiod: new command line option: --clock_diff_count
560
561 ---------------------------------------
562 0.2.13 (2006-07-14) "sonic convolution"
563 ---------------------------------------
564
565 A bunch of new features and core changes.
566
567 - the new paraslash scheduler, short and sweet.
568 - Support for m4a/mp4 files via the new aac audio format
569 handler/filter (requires libfaad).
570 - each writer has its own command line parser, just like
571 para_recv and para_filter.
572 - para_client and para_audioc use the error subsystem
573 - writers are integrated in para_audiod (currently linux-only)
574 - para_client is integrated in para_audiod
575 - random/playlist selector: improved info strings
576 - new audiod commands: tasks, kill
577 - update to libortp-0.10.1
578 - para_fade: wake time defaults to 8 hours from now
579 - update to autoconf-2.60
580
581 ------------------------------------------
582 0.2.12 (2006-05-12) "oriented abstraction"
583 ------------------------------------------
584
585 Many user-visible changes in this release and lots of new
586 features:
587
588
589 - the new optional dccp sender/receiver. It uses the datagram
590 congestion control protocol. You'll need a fairly new kernel
591 for this.
592 - paraslash works on Mac OS X (thanks to Gerd Becker)
593 - para_play renamed to para_write
594 - modular output plugin design (writers) for para_write
595 - new file_writer output plugin for para_write
596 - compress filter speed improvements
597 - update to libortp-0.9.1
598 - update to gengetopt-2.17rc
599 - para_client no longer depends on libreadline (as the
600 code for the interactive mode was removed).
601 - gcc-2-95 is no longer a supported compiler. It may still
602 work, but it gets no more testing.
603 - the tarball no longer contains the screenshot images which
604 reduces its size quite a bit.
605 - configure: new command line options: --enable-mysql-headers
606 and --enable-mysql-libs
607
608 ------------------------------------
609 0.2.11 (2006-03-11) "atomic duality"
610 ------------------------------------
611
612 Here it is, the first paraslash release developed with git. There
613 are fairly many user-visible changes in this release. As two out of
614 the three "database tools" of paraslash don't use a database at all,
615 they are now called "audio file selectors" instead.
616
617
618 - the cdt command (change database tool) becomes chs (change
619 selector)
620 - no more colon separators: The syntax of some options of
621 para_audiod and para_filter have changed. Use --help for
622 more info (and some examples).
623 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
624 - switch from cvs to git (should've done that earlier)
625 - the new ipc subsystem
626 - new audio file selector: playlist
627 - para_server: the dopey selector is now called "random",
628 and is the default selector. Use the --selector option to
629 choose another selector at startup, or the chs command to
630 change the selector at runtime.
631 - X86_64 fixes (thanks to Steffen Klassert)
632 - para_play fixes
633
634 --------------------------------------
635 0.2.10 (2006-02-17) "cyclic attractor"
636 --------------------------------------
637
638 Huge documentation update, a scrollable window for para_gui, ortp
639 improvements, and of course many small fixes not mentioned here.
640 The diffstat below is rather misleading as most insertions are due
641 to the new source documentation.
642
643 - autoconf cleanup
644 - para_server also uses the new error subsystem
645 - lots of new documentation (UTSL)
646 - gui improvements:
647 - keysyms for cursor keys and for next/previous page keys
648 - scrollable output window
649 - new internal commands: scroll up/down, page up/down
650 - fix color of command output.
651 - ortp: the --chunk_time and --header flags are no longer needed
652 for para_recv/para_audiod as this information is now encoded in
653 each rtp packet sent by para_server.
654
655 -------------------------------------------
656 0.2.9 (2006-01-24) "progressive turbulence"
657 -------------------------------------------
658
659 Internal audiod receivers/filters, the new error subsystem and
660 a lot of small improvements.
661
662 - para_recv and para_filter are integrated into the para_audiod
663 binary, i.e. audiod no longer spawns a new process for
664 each receiver/filter. As para_recv and para_filter might be
665 useful as standalone programs, they still get built (linked
666 against the same object files that are also used for audiod).
667 - further ortp timing improvements should reduce the CPU usage
668 of the ortp receiver.
669 - improved audio grabbing. The 'grab' command of para_audiod
670 has its own set of command line options. Read the output of
671 "para_audioc help grab" for more info.
672 - oggdec: configurable input prebuffer size.
673 - the new error subsystem gives better error diagnostics
674 and reduces code size.
675
676 -----------------------------------------
677 0.2.8 (2006-01-02) "dynamic accumulation"
678 -----------------------------------------
679
680 The new modular filter design and the para_play-hangs bugfix.
681
682 - new executable: para_filter. It combines para_mp3dec,
683 para_oggdec and para_compress. It also adds a further filter
684 type, wav, that just inserts a wave header at the desired point
685 of the filter chain. All 'piping' is done in-memory (i.e. no
686 read/write operations are used).
687 - para_play: fix a stupid bug that caused it to hang under
688 certain circumstances.
689
690 -------------------------------------------
691 0.2.7 (2006-12-27) "transparent invariance"
692 -------------------------------------------
693
694 Not many user-visible changes but a fair amount of internal improvements.
695
696
697 - The http sender buffers data if it can not be sent
698 out immediately (because the socket is not writable). This
699 should prevent para_server from shutting down the connection
700 too early on a loaded network.
701 - para_play also prebuffers data if it is told to start at a
702 future time by the --start_time option.
703 - The return of para_recv: It combines para_ortp_recv and
704 para_http_recv. Use the --receiver option to switch between
705 the two. para_recv builds without libortp, but contains
706 only the http receiver in this case.
707 - update to ortp 0.8.1. As this ortp release contains incompatible
708 changes, para_recv-0.2.7 won't link against older ortp libs.
709 - improved ortp timings.
710 - use of gcc-extensions that #define away for non-gcc and
711 gcc < 3.0.
712
713 -------------------------------------------
714 0.2.6 (2005-10-29) "recursive compensation"
715 -------------------------------------------
716
717 Transparent session encryption (uses openssl's Alleged RC4 cipher),
718 the internal find command and several other improvements and cleanups.
719
720 - Encrypt the session if encryption is requested by the client
721 (default for para_client 0.2.6). This is backwards
722 compatible, so older clients can still connect to para_server
723 0.2.6. Use the new client option --plain to request an
724 uncrypted session (off by default, must be set to on in
725 order to connect to para_server 0.2.x with 0 <= x <= 5).
726 - para_server uses an internal function to locate audio files
727 rather than calling find(1). The server option
728 --mysql_audio_file_dir replaces --mysql_find_cmd.
729 - documentation update
730 - man pages
731 - header file cleanup
732 - para_client code cleanup
733 - para_gui: faster display of output of display commands
734
735 ------------------------------------------
736 0.2.5 (2005-10-13) "aggressive resolution"
737 ------------------------------------------
738
739 This release adds internal senders, i.e. no more external programs are
740 spawned for sending out the audio data. There are two different senders
741 available: The http sender and the ortp sender (former para_send which
742 is no longer needed).
743
744 The new sender code has a plugin-like design so it can be easily
745 extended should there be be any future need for supporting another
746 network streaming protocol. All senders are completely independent of
747 each other. In particular, the http and the ortp sender can operate
748 in parallel.
749
750 - new server command: sender to control senders at runtime.
751 Read the output of "para_server -h" and "para_client help
752 sender" for more information.
753 - para_recv renamed to para_ortp_recv
754 - new executable: para_http_recv, a simple command line
755 http receiver.
756 - major afs/mp3/ogg code simplifications due to internal
757 senders.
758 - ogg timing improvements
759 - fix several minor memory leaks (found by valgrind)
760 - empty stream definitions work again
761 - com_ne(): ignore errors on remove
762 - audiod: fix segfault on server restart
763
764 ---------------------------------------
765 0.2.4 (2005-09-21) "toxic anticipation"
766 ---------------------------------------
767
768 Several small improvements, fixes and the new grab command.
769
770 - audiod:
771 - new command: "grab" to grab the output of the stream reader
772 or any filters. Read the output of "para_audioc help grab"
773 for more information.
774 - fix memory leak
775 - code cleanup
776 - audioc: new command line option: --bufsize to specify a
777 buffer size different from the default size 8192.
778 - improved error diagnostics for para_play.
779 - new configure option: --enable-ssldir so search for openssl in
780 non-standard places
781 - sdl_gui: Make it look nice again for 1024x768
782 - server: report total size of memory allocated with sbrk by malloc,
783 new command line option: --announce_time
784
785 -----------------------------------------
786 0.2.3 (2005-09-01) "hydrophilic movement"
787 -----------------------------------------
788
789 Two new executables and major feature enhancements.
790
791 - audiod filters: It is now possible to specify arbitrary many
792 (including none) filters for each supported audio
793 format. This can be used e.g. for normalizing volume,
794 transforming or grabbing the audio stream, or for using
795 visualizers. Read the output of "para_audiod -h" for the
796 syntax of the new --filter_cmd option.
797 - new executable: para_play, a tiny alsa player. It
798 can play wave files or raw pcm (16 bit little endian)
799 from stdin.
800 - new executable: para_compress, a dynamic range compressor
801 intended to keep audio output at a consistent volume. Derived
802 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
803 - audiod: New option: --stream_delay. This can be used in
804 a local network to syncronize the audio output of all
805 clients that play the same stream.
806
807 ------------------------------------------
808 0.2.2 (2005-08-19) "tangential excitation"
809 ------------------------------------------
810
811 Mostly internal changes in this release, but also some new commands
812 for the mysql database tool.
813
814 - cleanup exec.c, fix para_exec bug
815 - compile time loglevel (log messages below the given level
816 won't be compiled in, which reduces the size of the
817 resulting binaries)
818 - new log macros that shorten the size of the source code.
819 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
820 to send only zeros. With this workaround, para_audioc works
821 again.
822 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
823 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
824 (new entry), "snp" (set numplayed). Read the manual for more
825 information.
826
827 ---------------------------------------
828 0.2.1 (2005-08-15) "surreal experience"
829 ---------------------------------------
830
831 Here comes paraslash-0.2.1. It contains a couple of new features and,
832 surprise, only minor bug fixes.
833
834 - kill noisy mp3 debug message
835 - cleanup of the build system
836 - para_server and para_client directly use the crypto routines
837 of the openssl library rather than invoking the openssl command
838 line utitlity
839 - server/audiod: new option --user to switch to the given user
840 when invoked as root. Read the output of "para_server -h" for
841 more information.
842 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
843 status. Default: "para_audioc stat"
844 - sdl_gui: new option --pic_cmd to be used to download the picture.
845 Default: "para_client pic"
846 - audiod: 5 slots ought to be enough for everybody
847 - audiod: new status item: Uptime, kill hup command
848
849 ------------------------------------------
850 0.2.0 (2005-08-06) "distributed diffusion"
851 ------------------------------------------
852
853 After several month of increased development activity, paraslash-0.2.0
854 has arrived. It contains many new features and is much more
855 self-contained than the old 0.1.x series. Enjoy!
856
857
858 - para_server: fix hang on song change and crash on sighup.
859 Speed up mysql queries. The DIR_LIKE macro is gone.
860 - new executables: para_audiod, the local audio daemon that
861 starts playback (uses SCM_CREDENTIALS socket magic) and
862 para_audioc, the corresponding client.
863 - new executables: para_mp3dec/para_oggdec, two really teensy
864 decoders. para_mp3dec is based on libmad, para_oggdec requires
865 libvorbisfile.
866 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
867 they are now called para_send and para_recv respectively.
868 - documentation updates
869 - para_gui is themable. For now there is the default theme that
870 looks as before and the simple theme: blue and easy.
871 - gui: audio streaming is now handled by audiod. Time display shows
872 playback time rather than streaming time
873 - slider: update to libzmw-0.2.0
874 - para_krell: fix crash on server shutdown
875 - switch from gzip to bzip2
876
877 ----------------------------------------
878 0.1.7 (2005-04-18) "melting penetration"
879 ----------------------------------------
880
881 The main change in this release is clearly the oggvorbis rewrite,
882 but there are also lots of smaller changes. If you intend to use both
883 the mp3 and the ogg plugin, it is recommended to use software mixing,
884 e.g. the dmix plugin which is provided by ALSA.
885
886 - new executables: para_ovsend and para_ovrecv for sending/receiving
887 oggvorbis files via rtp. Requires the open rtp library. Get it at
888 http://www.linphone.org/ortp/
889 - rewrite of the ogg_vorbis core code
890 - configure detects libzmw and, if detected, includes
891 para_slider to the list of binaries to be built by make
892 - server stream writers read from their associated fifo rather
893 than from stdin
894 - slider: two new sliders, lastplayed and numplayed
895 - fix nasty double free bug which caused random segfaults in case of
896 mp3 files with invalid header information
897 - gui: new command line option: --stream_timeout=seconds to
898 deactivate a slot if it is idle for that many seconds (default=`5')
899 - diffstats
900
901 ---------------------------------------
902 0.1.6 (2005-03-05) "asymptotic balance"
903 ---------------------------------------
904
905 Only little user-visible changes in this release. Mainly bugfixes and
906 core code cleanup. This is probably the most stable version ever if you
907 stick to mp3...
908
909 - fix several memory leaks
910 - rename default name of mysql database from "music" to "paraslash".
911 Use para_server's --mysql_database option if you do not want to
912 rename your old database.
913 - rework ogg vorbis code
914 - make update command work on mysql servers with LOCAL_INFILE
915 disabled
916 - gui: improved stream I/O (slots)
917 - simplified audio format API
918 - para_pob_ogg is gone
919
920 ------------------------------------
921 0.1.5 (2004-12-31) "opaque eternity"
922 ------------------------------------
923
924 Let's slide gently into the new year.
925
926 - new: para_slider (not built automatically, type "make
927 para_slider" to build). A toy for those who always felt that
928 creating stream definitions is difficult. See screenshots,
929 README and FEATURES for more info.
930 - improved signal handling. Fixes server segfault on SIGHUP
931 for linux kernels newer than Aug 24 2004 and makes para_gui
932 race-free.
933 - reload database tool on SIGHUP
934 - improved help message for sl
935 - do not log "broken pipe" messages as errors. They are
936 perfectly ok.
937 - fix wrong error message on permission errors
938
939 -----------------------------------------
940 0.1.4 (2004-12-19) "tunneling transition"
941 -----------------------------------------
942
943 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
944 Hopefully, most of them got wiped out with this release. Some
945 enhancements went also in.
946
947 - improved error diagnostics for all commands
948 - stradd/picadd: overwrite previous contents if entry already
949 exists, rather than returning errors
950 - stradd: use current stream if invoked without args
951 - faster (and hopefully more stable) ogg-vorbis handling
952 - para_krell: reap children to avoid zombie-flooding in case
953 no server is running
954 - si: report also server pid
955 - server: don't busy-loop if dbtool reports only invalid files.
956 - gui: CTRL+C works again, fix stream_read command line option
957 - fix pic_add, hist
958 - fix mysql dbtool startup in case no database exists
959 - many small fixes and cleanups
960
961 ---------------------------------------
962 0.1.3: (2004-12-10) "vanishing inertia"
963 ---------------------------------------
964
965 Starting from this release, the database tools are integrated in the
966 server binary. This decreases server startup time, reduces code size
967 and speeds up database commands. However, the layout of the underlying
968 mysql database changed only slightly and 0.1.3 should be backwards
969 compatible in that respect.
970
971 Visible changes:
972
973 - If mysql is not detected at compile time, or fails to init
974 at runtime, fall back to the dopey database tool which should
975 always work.
976 - para_dbtool and dbtool.conf are gone. All mysql specific
977 options are read from server.conf and are prefixed by 'mysql_'.
978 - new command: cdt (change database tool)
979 - new command line option: dbtool (choose startup database tool)
980 - The name of current stream is now stored in the database,
981 so paraslash remembers its current stream when restarted.
982 - new command: csp (change stream and play)
983 - para_gui also reports current database tool and server uptime
984
985 -------------------------------------------
986 0.1.2: (2004-11-28) "spherical fluctuation"
987 -------------------------------------------
988
989 Point release before the big dbtool changes go in.
990
991 - dbtool: rename ca to cam (copy all meta data). It now also
992 copies numplayed and lastplayed time as well as the picture
993 id.
994 - fix endless-loop-bug caused by mp3 files with invalid header
995
996 -----------------------------------------
997 0.1.1: (2004-11-05) "floating atmosphere"
998 -----------------------------------------
999
1000 - gkrellm plugin
1001 - new dbtool command: mbox. Browse your sound-file collection
1002 with your favorite mail reader.
1003 - several small fixes
1004
1005 -------------------------------------
1006 0.1.0: (2004-10-22) "rotating cortex"
1007 -------------------------------------
1008
1009 - fix logging bug for loglevel > VERBOSE
1010 - fix skip command
1011 - correct timings for vbr mp3s
1012 - modular audio format support
1013 - ogg-vorbis support (experimental)
1014 - new server option: autoplay
1015
1016 -----------------------------------------
1017 0.0.99: (2004-07-25) "harmonic deviation"
1018 -----------------------------------------
1019
1020 - rename projectname from icc to paraslash (play, archive, rate
1021 and stream large audio sets happily)
1022 - paraslash is no longer restricted to one particular audio
1023 streaming software
1024 - new dbtool commands (stradd, strq, strdel) for easy stream
1025 managment w/o configuration file. That obsoletes stream_defs
1026 file/config option for dbtool.
1027 - picadd accepts jpeg data from stdin
1028 - new server commands: ps (select previous stream), sc (song change)
1029 - new default pictures for sdl_gui
1030 - gui: new key_map option for binding commands and internal
1031 functions to arbitrary keys, nice help screen, rip out
1032 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1033 show silly logo on startup
1034 - new executables: para_fade for fading volume, para_dbadm for
1035 manipulating attributes
1036 - cdb adds _all_ tables to mysql database
1037 - revised and beautified documentation
1038 - sample dbtool rewritten in C
1039 - autoconf
1040
1041 ---------------------------------------------
1042 0.0.98: (2003-12-26) "incremental smoothness"
1043 ---------------------------------------------
1044
1045 - kick icecast in favour of poc. That removes some races and reduces
1046 core code considerably.
1047 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1048 give finer info on afs' status.
1049 - gui can start decoder (see config options). Further new gui
