Merge branch 't/dia'
[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 - overview.pdf is now based on dia, a simple diagram creation program.
15 The new version is much more detailed and contains descriptions of
16 the various programs of the paraslash package.
17
18 --------------------------------------
19 0.4.13 (2013-07-29) "spectral gravity"
20 --------------------------------------
21
22 One more 0.4.x release before the API-breaking changes for 0.5.0 go
23 in. The main features of this release are the ogg/opus audio format,
24 and UTF-8 support, but it includes also tons of other improvements
25 and fixes all over the place.
26
27 - New audio format: ogg/opus.
28 - UTF8 support for para_gui and the mp3 audio format handler.
29 - Scheduler improvements and fixes.
30 - The obsolete gettimeofday() function has been replaced
31 by clock_gettime() on systems which support it.
32 - Speed and usability improvements for para_gui.
33 - para_client now restores the fd flags of stdin and stdout
34 on shutdown.
35 - Improved manual pages.
36 - Consistent version strings for all executables.
37 - Reduced dependencies on generated files result in fewer
38 recompilations on changes.
39 - Performance improvements for the compress filter.
40 - Improved downloads web page.
41
42 -----------------------------------------
43 0.4.12 (2012-12-20) "volatile relativity"
44 -----------------------------------------
45 The new command line player, the resample filter, ALSA support for
46 para_fade, and the improved build system are the highlights of this
47 release which probably marks the end of the 0.4.x series.
48
49 - The afh receiver and the para_play executable.
50 - The resample filter: A sample rate converter based on
51 libsamplerate.
52 - The "versions" directory has been removed from the master
53 branch. The tarballs of the old releases are now available
54 in the new "releases" branch.
55 - Overhaul of the build system: All generated files are now
56 written to the "build" directory.
57 - The modular mixer API and the alsa mixer.
58 - Minor fixes for the osx writer.
59
60 --------------------------------------
61 0.4.11 (2012-07-20) "mutual diversity"
62 --------------------------------------
63
64 The major feature in this release is the new sideband API for
65 client-server communication. This API will be used exclusively starting
66 with 0.5.0, which breaks backward compatibility but allows to get rid
67 of quite some compatibility code. Other noteworthy changes include
68 decoder latency improvements and a long-standing bug fix for the
69 ALSA writer.
70
71 - Sideband connections: If both para_server and para_client
72 support this feature, data is sent as a multiplexed stream.
73 - The --no_default_filters option of para_filter has been
74 removed.
75 - Several fixes and latency improvements to various decoders.
76 - The ALSA writer now limits the prebuffer time to 500ms.
77 - Documentation improvements.
78 - Overhaul of the command_util.sh script.
79 - Fixes for some minor problems found by the clang analyzer.
80 - Compiles (almost) without warnings on gcc-3.
81 - Robustness improvements of the buffer tree code.
82
83 ------------------------------------------
84 0.4.10 (2012-03-30) "heterogeneous vacuum"
85 ------------------------------------------
86
87 Nothing earth-shaking in this release, but quite a few usability
88 improvements and the usual mix of cleanups and fixes.
89
90 - The --no_default_filters option of para_filter has been
91 deprecated. It still works but has no effect and will be
92 removed in the next version.
93 - para_gui now prints also the stderr output of the executing
94 command in the bottom window.
95 - Cleanup and consolidation of the various wrappers for
96 write(), writev(), send() and friends.
97 - The obscure error messages on mmap() failures have been
98 replaced by meaningful messages. This affects mainly
99 para_afh.
100 - para_audioc: Cleanups and memory leak fixes.
101 - Test 0004-server no longer fails if para_server is not
102 being built.
103 - New configure options: --with-id3tag-{headers,libs}.
104
105 -------------------------------------
106 0.4.9 (2011-12-06) "hybrid causality"
107 -------------------------------------
108
109 Support for another audio format, interactive mode for para_client
110 and para_audiod and many small improvements/fixes all over the place.
111
112 - Support for flac, the free lossless audio codec.
113 - Fix for an endless loop in the mp3 decoder for certain
114 (corrupt) mp3 files.
115 - When executed without specifying a command, para_client
116 and para_audioc start an interactive shell (requires
117 libreadline being installed). The interactive mode offers
118 full tab completion and command line history.
119 - autogen.sh now detects a distcc setup and adjusts the
120 parameter for the -j option of make accordingly.
121 - Shared memory areas are no longer restricted to 64K. We now
122 detect the maximal size of a shared memory area at runtime.
123 - cleanup of the internal uptime API.
124 - para_server prefaults the mmapped audio file to avoid
125 delays on slow media.
126 - A new test for the test-suite that exercises the
127 communication between para_server and para_audiod.
128 - The alsa writer eats up less CPU cycles when configured to
129 use the DMIX plugin.
130 - Simplified and unified receiver code.
131 - Makefile cleanups.
132 - Commands which print a list of matching audio files now
133 emit a meaningful error message if no audio file matched the
134 given pattern(s).
135
136 --------------------------------------
137 0.4.8 (2011-08-19) "nested assignment"
138 --------------------------------------
139
140 Gcrypt support, the overhauled osx writer and regex format specifiers
141 are the highlights of this release.
142
143 - support for libgcrypt as a drop-in replacement for openssl.
144 Run configure --enable-cryptolib=gcrypt to link against
145 libgcrypt. The two crypto implementations are compatible to
146 each other, i.e. a para_client executable linked against
147 gcrypt can connect to para_server linked against libssl
148 and vice versa.
149 - Rewrite of the osx writer (output plugin for Mac OS).
150 - audiod: The format specifier for receivers, filters and
151 writers is now treated as a regular expression. This allows
152 to replace 5 lines in the config file (one for each audio
153 format) by one single line. See the manual for details.
154 - The *.cmdline.[ch] files are no longer contained in the released
155 tarballs. This reduces the size of the tarballs but requires
156 gengetopt to build the tarball.
157 - Compiles cleanly also with llvm/clang.
158 - Corrupt mp3 files are handled more gracefully.
159 - The alsa writer uses poll fds instead of computing timeouts.
160 - Cleanup of the generic writer API.
161 - sched: Optimized zero timeouts.
162 - vss timeout cleanups.
163 - oggdec fixes and improvements.
164
165 --------------------------------------
166 0.4.7 (2011-06-01) "infinite rollback"
167 --------------------------------------
168
169 The new ao writer, support for ssh RSA keys and a couple of other
170 enhancements.
171
172 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
173 platforms through the libao audio library.
174 - Support for RSA keys generated with ssh-keygen.
175 - configure: improved options for ogg/vorbis/speex.
176 - The git version reported by --version always matches HEAD.
177 - The autogen script detects the number of processors and
178 runs a parallel make if possible.
179 - Major cleanup of the crypto API.
180 - Documentation updates.
181
182 ------------------------------------------
183 0.4.6 (2011-03-31) "deterministic entropy"
184 ------------------------------------------
185
186 Lots of ogg/vorbis improvements, the new test suite, enhancements
187 for para_gui and a fair amount of other bug fixes.
188
189 - For DCCP/OGG streams the audio file header is only sent once
190 at the beginning of the stream rather than periodically
191 every five seconds. This reduces network traffic and the
192 FEC group size.
193 - The vorbis comment header is replaced by an empty dummy header
194 before the header is sent over the network. This also results in
195 less network traffic and smaller FEC groups.
196 - The new "test" make target allows to perform some sanity checks prior
197 to installing the package.
198 - ogg timing fixes and performance improvements
199 - Scheduler improvements
200 - Proper exit codes for para_write
201 - para_gui: New option --theme to select a startup theme. Several
202 other improvements and fixes.
203 - aacdec error message cleanups
204 - simplified color error handling
205
206 --------------------------------------------
207 0.4.5 (2010-12-17) "symmetric randomization"
208 --------------------------------------------
209
210 Bug fixes, internal cleanups and variable-sized FEC slices.
211
212 - Contains a fix for an invalid-free-bug in the ogg audio format
213 handler code.
214 - Switching off the DCCP sender works again.
215 - para_audiod handles crashes of para_server more robustly.
216 - Internal scheduler and writer cleanups.
217 - Reduced latency due to variable-sized FEC slices.
218 - Improved documentation and error diagnostics.
219 - The build of para_server is now optional, allowing the build
220 to succeed in case libosl is not installed.
221
222 ------------------------------------------
223 0.4.4 (2010-08-06) "persistent regularity"
224 ------------------------------------------
225
226 Support for yet another audio format, para_write improvements and
227 bug fixes.
228
229 - Support for the speex codec.
230 - Support for sample formats other than 16 bit little endian.
231 - error2.h is now created by a perl script which speeds up configure
232 considerably.
233 - Fix a bug in the aac decoder which could lead to segfaults in
234 para_filter/para_audiod.
235 - Fixes for autoconf-2.66.
236
237 ----------------------------------------
238 0.4.3 (2010-07-05) "imaginary radiation"
239 ----------------------------------------
240
241 Many improvements for the DCCP and the UDP transport, the new user
242 manual and the usual mix of bug fixes and internal improvements.
243
244 - FEC support for the DCCP sender (Gerrit Renker). The new
245 --dccp_max_slice_size, --dccp_data_slices_per_group and
246 --dccp_slices_per_group options can be used to set the FEC
247 parameters for the DCCP transport.
248 - DNS lookups for UDP targets (Gerrit Renker).
249 - The new user manual replaces the README, README.afs, REQUIREMENTS
250 and INSTALL documents.
251 - Fix an end-of-file detection bug in the oggdec filter.
252 - The new nonblock API.
253 - Both options of the oggdec filter have been removed.
254 - New debug mode for the internal scheduler.
255
256 ------------------------------------------
257 0.4.2 (2010-04-23) "associative expansion"
258 ------------------------------------------
259
260 It's been some time since the last release, but finally here is
261 paraslash-0.4.2. The bulk of the changes comes from the new buffer
262 tree API, but there are changes all over the tree. Mainly performance
263 and usability improvements, but also quite some bug fixes.
264
265 - The new buffer tree API.
266 - DCCP: Support for CCID negotiation (Gerrit Renker).
267 - UDP robustness fixes.
268 - The --bufsize option for mp3dec is gone as it no longer makes sense
269 for the new buffer tree API.
270 - Fix audible buffer underruns for wma streams.
271 - The alsa writer no longer prints meaningless underrun durations.
272 - audiod: Defaults work also for udp streams. If no filter is
273 given for an audio format that is received via upd, fecdec is
274 automatically added as the first filter (along with the decoder).
275
276 ---------------------------------------
277 0.4.1 (2009-12-22) "concurrent horizon"
278 ---------------------------------------
279
280 Support for another audio format, minor feature enhancements and lots of bug
281 fixes. All fixes that have been accumulated in the maint branch (in particular
282 those mentionened in the 0.3.6 release notes) appear in this release as well.
283
284 - wma support.
285 - new afh option: --human to activate human-readable output.
286 - new server/audiod option: --log-timing to print timing information.
287 - build system improvements.
288 - source code documentation updates.
289
290 -------------------------------------
291 0.3.6 (2009-12-07) "cubic continuity"
292 -------------------------------------
293
294 Quite a few bugs have been found and fixed since 0.3.5, so here's
295 another 0.3.x release. No new features.
296
297 - Always check return value of malloc().
298 - ogg vorbis/FEC: Do not write garbage after the audio file header.
299 - exit if root privileges could not be dropped.
300 - FEC: Fix computation of extra slices.
301 - oss: Fix check for empty input buffer.
302 - Avoid buffer underruns due to filter chain output buffer constraints.
303 - server: Fix assignment of afs_pid.
304 - Don't panic if the afs database contains unknown audio formats.
305 - http/dccp: Do not send the audio file header twice.
306 - FEC: Timing improvements.
307
308 ----------------------------------------------
309 0.4.0 (2009-11-10) "simultaneous independence"
310 ----------------------------------------------
311
312 Two significant changes which require the new version number: The
313 improved authentication dialog and the fact that the database code
314 has been moved to a library, libosl. To use the new version, you have
315 to generate new RSA keys, see INSTALL for details. A shell script is
316 provided for conversion of the 0.3 database to the new 0.4 format.
317
318 - stronger crypto for client authentication
319 - the database code has been moved to a library
320 - improved status item handling
321 - cleanup of the build system
322 - The "-V" option now also prints the git version
323 - the new parser-friendly listing mode for the ls and stat commands
324 - mandatory rc4 encryption
325 - major audio format handler cleanups
326 - (id3,...) tags are no longer stored as a combined string in the database
327 - new mood methods: artist_matches, title_matches, comment_matches,
328 album_matches, year_maches, year.
329
330 --------------------------------------------
331 0.3.5 (2009-09-21) "symplectic separability"
332 --------------------------------------------
333
334 Full client support for *BSD Unixes, complete re-write of the ogg
335 vorbis audio format handler, various improvements all over the place
336 and the usual mix of bugfixes. This release marks the end of the 0.3
337 series if no serious problems show up.
338
339 - the new oss writer (supported on *BSD and Linux)
340 - rewrite of the ogg vorbis audio format handler. It's
341 recommended to replace the chunk tables of existing ogg
342 vorbis files in the afs database by re-adding these files
343 with "add -f".
344 - support for netmask subsets (Gerrit Renker)
345 - the new prebuffer filter
346 - improved signal handling
347 - variable fec output buffer size
348 - improved FEC timing fixes audible buffer underruns in UDP mode
349 - --log_color actually works
350 - new ls option: -d (print dates as seconds after the epoch)
351 - update to gengetopt 2.22.2
352 - support for RSA keys of size > 512 bits
353 - new option "mixer_channel" for para_fade
354
355 -----------------------------------------
356 0.3.4 (2009-05-07) "elliptic inheritance"
357 -----------------------------------------
358
359 The new udp sender, forward error correction, colored logs and various
360 other improvements. As the udp sender does not depend on any special
361 libraries, it is built unconditionally.
362
363 - The udp sender replaces the ortp sender. The new code uses forward
364 error correction to protect against packet losses. Many thanks to
365 Gerrit Renker for providing ipv6 support.
366 - The default port for udp streaming now defaults to 8000, like
367 for the http and the dccp senders/receivers.
368 - Loglevels are now specified as symbolic names, e.g.
369 "--loglevel info".
370 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
371 - para_server/para_audiod: Color support for log messages.
372 - new options for mp3dec: --ignore-crc, --bufsize
373 - new audiod option: --config-file.
374 - gengetopt cleanups.
375 - Improved help/man pages: The documentation of para_audiod,
376 para_recv, para_filter and para_write now also contains
377 all options of the available receivers/filters/writers. The
378 man page of para_fade contains a description of the different
379 modes of operation.
380 - More source code documentation.
381 - vss timing fixes.
382
383 --------------------------------------------
384 0.3.3 (2008-12-01) "axiomatic perspectivity"
385 --------------------------------------------
386
387 Internal code cleanups, bug fixes, improved tag handling and the new
388 amplification filter.
389
390 - para_server uses the generic scheduling code.
391 - overhaul of the virtual streaming system.
392 - mp3: id3 version 2 support via libid3tag (optional)
393 - ogg: vorbis comment support.
394 - aac meta info support.
395 - mp3 audio format handler cleanups.
396 - new filter: "amp" to amplify the amplitude of the audio stream
397 - new status item/database entry: amplification. It is
398 used by the amp filter to pre-amplify the audio stream.
399 - fix a close-without-open bug in para_write.
400 - fix a bug in com_init() which was introduced in 0.3.2.
401 - better error diagnostics for para_client.
402
403 -----------------------------------------
404 0.3.2 (2008-04-11) "probabilistic parity"
405 -----------------------------------------
406
407 The new para_afh executable, scheduling and documentation improvements.
408
409 - new ls option: -lc (list chunk table)
410 - new executable: para_afh, the stand-alone audio file handler tool
411 - afs commands can send output more than SHMMAX (32MB on Linux). This
412 also reduces the memory usage of commands that produce large amounts
413 of output.
414 - major scheduler and audiod cleanups.
415 - more detailed and much nicer man pages.
416
417 ---------------------------------------
418 0.3.1 (2008-02-23) "liquid interaction"
419 ---------------------------------------
420
421 A mix of cleanups, bug fixes, improvements, and some new features. No
422 significant changes to the new database (osl) code, which is generally
423 a good sign.
424
425 - Share some similar/duplicate code between the http and the
426 dccp sender.
427 - Generic access control lists for paraslash senders.
428 - dccp sender: Access control lists, connection limiting and support
429 for the allow,deny,on,off,help sender commands.
430 - The default dccp port changed from 5001 to 8000 (suggested by
431 Gerrit Renker).
432 - para_server starts even if not all public keys could be loaded.
433 - Audiod performance improvements.
434 - fix a bug in the "off" command of the http sender.
435 - fix some fd and memory leaks.
436 - Update to gengetopt-2.22.
437
438 -------------------------------------
439 0.3.0 (2008-01-12) "solar saturation"
440 -------------------------------------
441
442 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
443
444
445 Usually one might expect lots of new features AND a big increase in size
446 for a major release like this.
447
448 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
449 ever. The decrease in size is mostly due to the removal of some
450 graphical tools (which were only quick hacks anyway). But also the
451 fact that the mysql code is gone cuts down the size a bit.
452
453 Being independent of mysql comes at a cost: The fact that paraslash
454 now contains its own database (the object storage layer, osl) increases
455 the (stripped) binary size of para_server by ~50K on i386.
456
457 - no more restrictions on unique basenames.
458 - independent of mysql: The new self-contained object
459 storage layer (osl) replaces the mysql database.
460 - New executable para_fsck: Check integrity of osl tables.
461 - Lyrics support.
462 - Reliable audio file move/rename detection.
463 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
464 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
465 Solaris (sparc64).
466 - the new osl-based audio file selector (afs) replaces the random,
467 the playlist and the mysql selector of paraslash-0.2.x.
468 - IPv6 support (thanks to Gerrit Renker).
469 - paraslash-0.2.x streams are now called "moods". Writing
470 0.3.x-mood definitions should be both easier and more
471 powerful than writing 0.2.x-stream definitions.
472 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
473 been removed. The world is a better place without them. However,
474 para_gui is still there.
475 - afs tracks audio file selection also in playlist mode.
476 - few easy-to-use afs commands replace the many not-so-easy-to-use
477 mysql commands (and are available also in playlist mode).
478 - Improved error subsystem.
479 - The earth-shaking new logo.
480
481 -----------------------------------------
482 0.2.17 (2007-11-20) "isotropic threshold"
483 -----------------------------------------
484
485 Mainly bugfixes and cleanups in this version which marks the end of
486 the 0.2.x series if no serious bugs show up after the release.
487
488 - mysql_selector: fix a locking bug.
489 - universal chunk queueing.
490 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
491 to Gerrit Renker).
492 - be more carful wrt. signed vs. unsigned argument passing.
493 - cleanup error.h and fix some references to invalid error
494 codes.
495 - update to gengetopt-2.21.
496 - update to ortp-0.13.1.
497 - autoconf: extend checks for headers, library functions and
498 compiler characteristics.
499 - Fix streaming of large mp3 files.
500 - Fix an off-by-one bug in playlist handling.
501
502 --------------------------------------
503 0.2.16 (2007-04-05) "neural discharge"
504 --------------------------------------
505
506 The main change in this release is the major audio format handler
507 cleanup which removes some similar/duplicate code and makes it easier
508 to implement plugins for other audio formats. Of course, the usual mix
509 of other improvements/changes/bugfixes also made it into the release.
510
511 - simplified audio format handlers (most of the handling functions
512 were moved one layer up to the virtual streaming system).
513 - para_server uses mmap to read audio files
514 - repositioning of mp3 streams is much faster, in particular for
515 jumping near the end of large mp3 files.
516 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
517 and AFS_WRITE.
518 - fix a bug in para_filter that caused decoding of aac files
519 to start only after a few seconds.
520 - fix osx_writer hangs
521 - simplified dccp code (thanks to Gerrit Renker)
522 - the compress filter works also on big endian systems (ppc)
523
524 -----------------------------------------
525 0.2.15 (2007-02-16) "inductive resonance"
526 -----------------------------------------
527
528 Minor improvements, more documentation and a bunch of bug fixes.
529
530 - para_server: The server.users file is only read once on server
531 startup rather than for each connection
532 - mp3dec: Fix decoding of corrupt mp3 files
533 - afs (audio file sender) is now called vss (virtual streaming
534 system). Consequently, the permission flags specified in
535 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
536 become VSS_READ and VSS_WRITE respectively.
537 - para_audiod/para_filter: Fix a bug that caused the last chunk
538 of audio data not being written under certain circumstances
539 - audiod: compute the difference of server time and local time
540 correctly
541 - para_server/para_audiod: Fix some memory leaks
542 - documentation improvements
543 - configure.ac: fix checks for para_krell
544 - new man pages
545
546 -------------------------------------------
547 0.2.14 (2006-10-15) "transient singularity"
548 -------------------------------------------
549
550 The only major enhancement of this version is the osx writer which completes
551 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
552 until now for reasons beyond the scope of this changelog entry.
553
554 - new output plugin for Mac Os: the osx writer
555 - rename configure command line options from --enable-xxx-headers to
556 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
557 - configure: new command line options: --with-mad-headers,
558 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
559 - some robustness fixes
560 - dymamic audio format recognition for audiod
561 - para_server: new command line option: --autoplay_delay
562 - para_audiod: new command line option: --clock_diff_count
563
564 ---------------------------------------
565 0.2.13 (2006-07-14) "sonic convolution"
566 ---------------------------------------
567
568 A bunch of new features and core changes.
569
570 - the new paraslash scheduler, short and sweet.
571 - Support for m4a/mp4 files via the new aac audio format
572 handler/filter (requires libfaad).
573 - each writer has its own command line parser, just like
574 para_recv and para_filter.
575 - para_client and para_audioc use the error subsystem
576 - writers are integrated in para_audiod (currently linux-only)
577 - para_client is integrated in para_audiod
578 - random/playlist selector: improved info strings
579 - new audiod commands: tasks, kill
580 - update to libortp-0.10.1
581 - para_fade: wake time defaults to 8 hours from now
582 - update to autoconf-2.60
583
584 ------------------------------------------
585 0.2.12 (2006-05-12) "oriented abstraction"
586 ------------------------------------------
587
588 Many user-visible changes in this release and lots of new
589 features:
590
591
592 - the new optional dccp sender/receiver. It uses the datagram
593 congestion control protocol. You'll need a fairly new kernel
594 for this.
595 - paraslash works on Mac OS X (thanks to Gerd Becker)
596 - para_play renamed to para_write
597 - modular output plugin design (writers) for para_write
598 - new file_writer output plugin for para_write
599 - compress filter speed improvements
600 - update to libortp-0.9.1
601 - update to gengetopt-2.17rc
602 - para_client no longer depends on libreadline (as the
603 code for the interactive mode was removed).
604 - gcc-2-95 is no longer a supported compiler. It may still
605 work, but it gets no more testing.
606 - the tarball no longer contains the screenshot images which
607 reduces its size quite a bit.
608 - configure: new command line options: --enable-mysql-headers
609 and --enable-mysql-libs
610
611 ------------------------------------
612 0.2.11 (2006-03-11) "atomic duality"
613 ------------------------------------
614
615 Here it is, the first paraslash release developed with git. There
616 are fairly many user-visible changes in this release. As two out of
617 the three "database tools" of paraslash don't use a database at all,
618 they are now called "audio file selectors" instead.
619
620
621 - the cdt command (change database tool) becomes chs (change
622 selector)
623 - no more colon separators: The syntax of some options of
624 para_audiod and para_filter have changed. Use --help for
625 more info (and some examples).
626 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
627 - switch from cvs to git (should've done that earlier)
628 - the new ipc subsystem
629 - new audio file selector: playlist
630 - para_server: the dopey selector is now called "random",
631 and is the default selector. Use the --selector option to
632 choose another selector at startup, or the chs command to
633 change the selector at runtime.
634 - X86_64 fixes (thanks to Steffen Klassert)
635 - para_play fixes
636
637 --------------------------------------
638 0.2.10 (2006-02-17) "cyclic attractor"
639 --------------------------------------
640
641 Huge documentation update, a scrollable window for para_gui, ortp
642 improvements, and of course many small fixes not mentioned here.
643 The diffstat below is rather misleading as most insertions are due
644 to the new source documentation.
645
646 - autoconf cleanup
647 - para_server also uses the new error subsystem
648 - lots of new documentation (UTSL)
649 - gui improvements:
650 - keysyms for cursor keys and for next/previous page keys
651 - scrollable output window
652 - new internal commands: scroll up/down, page up/down
653 - fix color of command output.
654 - ortp: the --chunk_time and --header flags are no longer needed
655 for para_recv/para_audiod as this information is now encoded in
656 each rtp packet sent by para_server.
657
658 -------------------------------------------
659 0.2.9 (2006-01-24) "progressive turbulence"
660 -------------------------------------------
661
662 Internal audiod receivers/filters, the new error subsystem and
663 a lot of small improvements.
664
665 - para_recv and para_filter are integrated into the para_audiod
666 binary, i.e. audiod no longer spawns a new process for
667 each receiver/filter. As para_recv and para_filter might be
668 useful as standalone programs, they still get built (linked
669 against the same object files that are also used for audiod).
670 - further ortp timing improvements should reduce the CPU usage
671 of the ortp receiver.
672 - improved audio grabbing. The 'grab' command of para_audiod
673 has its own set of command line options. Read the output of
674 "para_audioc help grab" for more info.
675 - oggdec: configurable input prebuffer size.
676 - the new error subsystem gives better error diagnostics
677 and reduces code size.
678
679 -----------------------------------------
680 0.2.8 (2006-01-02) "dynamic accumulation"
681 -----------------------------------------
682
683 The new modular filter design and the para_play-hangs bugfix.
684
685 - new executable: para_filter. It combines para_mp3dec,
686 para_oggdec and para_compress. It also adds a further filter
687 type, wav, that just inserts a wave header at the desired point
688 of the filter chain. All 'piping' is done in-memory (i.e. no
689 read/write operations are used).
690 - para_play: fix a stupid bug that caused it to hang under
691 certain circumstances.
692
693 -------------------------------------------
694 0.2.7 (2006-12-27) "transparent invariance"
695 -------------------------------------------
696
697 Not many user-visible changes but a fair amount of internal improvements.
698
699
700 - The http sender buffers data if it can not be sent
701 out immediately (because the socket is not writable). This
702 should prevent para_server from shutting down the connection
703 too early on a loaded network.
704 - para_play also prebuffers data if it is told to start at a
705 future time by the --start_time option.
706 - The return of para_recv: It combines para_ortp_recv and
707 para_http_recv. Use the --receiver option to switch between
708 the two. para_recv builds without libortp, but contains
709 only the http receiver in this case.
710 - update to ortp 0.8.1. As this ortp release contains incompatible
711 changes, para_recv-0.2.7 won't link against older ortp libs.
712 - improved ortp timings.
713 - use of gcc-extensions that #define away for non-gcc and
714 gcc < 3.0.
715
716 -------------------------------------------
717 0.2.6 (2005-10-29) "recursive compensation"
718 -------------------------------------------
719
720 Transparent session encryption (uses openssl's Alleged RC4 cipher),
721 the internal find command and several other improvements and cleanups.
722
723 - Encrypt the session if encryption is requested by the client
724 (default for para_client 0.2.6). This is backwards
725 compatible, so older clients can still connect to para_server
726 0.2.6. Use the new client option --plain to request an
727 uncrypted session (off by default, must be set to on in
728 order to connect to para_server 0.2.x with 0 <= x <= 5).
729 - para_server uses an internal function to locate audio files
730 rather than calling find(1). The server option
731 --mysql_audio_file_dir replaces --mysql_find_cmd.
732 - documentation update
733 - man pages
734 - header file cleanup
735 - para_client code cleanup
736 - para_gui: faster display of output of display commands
737
738 ------------------------------------------
739 0.2.5 (2005-10-13) "aggressive resolution"
740 ------------------------------------------
741
742 This release adds internal senders, i.e. no more external programs are
743 spawned for sending out the audio data. There are two different senders
744 available: The http sender and the ortp sender (former para_send which
745 is no longer needed).
746
747 The new sender code has a plugin-like design so it can be easily
748 extended should there be be any future need for supporting another
749 network streaming protocol. All senders are completely independent of
750 each other. In particular, the http and the ortp sender can operate
751 in parallel.
752
753 - new server command: sender to control senders at runtime.
754 Read the output of "para_server -h" and "para_client help
755 sender" for more information.
756 - para_recv renamed to para_ortp_recv
757 - new executable: para_http_recv, a simple command line
758 http receiver.
759 - major afs/mp3/ogg code simplifications due to internal
760 senders.
761 - ogg timing improvements
762 - fix several minor memory leaks (found by valgrind)
763 - empty stream definitions work again
764 - com_ne(): ignore errors on remove
765 - audiod: fix segfault on server restart
766
767 ---------------------------------------
768 0.2.4 (2005-09-21) "toxic anticipation"
769 ---------------------------------------
770
771 Several small improvements, fixes and the new grab command.
772
773 - audiod:
774 - new command: "grab" to grab the output of the stream reader
775 or any filters. Read the output of "para_audioc help grab"
776 for more information.
777 - fix memory leak
778 - code cleanup
779 - audioc: new command line option: --bufsize to specify a
780 buffer size different from the default size 8192.
781 - improved error diagnostics for para_play.
782 - new configure option: --enable-ssldir so search for openssl in
783 non-standard places
784 - sdl_gui: Make it look nice again for 1024x768
785 - server: report total size of memory allocated with sbrk by malloc,
786 new command line option: --announce_time
787
788 -----------------------------------------
789 0.2.3 (2005-09-01) "hydrophilic movement"
790 -----------------------------------------
791
792 Two new executables and major feature enhancements.
793
794 - audiod filters: It is now possible to specify arbitrary many
795 (including none) filters for each supported audio
796 format. This can be used e.g. for normalizing volume,
797 transforming or grabbing the audio stream, or for using
798 visualizers. Read the output of "para_audiod -h" for the
799 syntax of the new --filter_cmd option.
800 - new executable: para_play, a tiny alsa player. It
801 can play wave files or raw pcm (16 bit little endian)
802 from stdin.
803 - new executable: para_compress, a dynamic range compressor
804 intended to keep audio output at a consistent volume. Derived
805 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
806 - audiod: New option: --stream_delay. This can be used in
807 a local network to syncronize the audio output of all
808 clients that play the same stream.
809
810 ------------------------------------------
811 0.2.2 (2005-08-19) "tangential excitation"
812 ------------------------------------------
813
814 Mostly internal changes in this release, but also some new commands
815 for the mysql database tool.
816
817 - cleanup exec.c, fix para_exec bug
818 - compile time loglevel (log messages below the given level
819 won't be compiled in, which reduces the size of the
820 resulting binaries)
821 - new log macros that shorten the size of the source code.
822 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
823 to send only zeros. With this workaround, para_audioc works
824 again.
825 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
826 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
827 (new entry), "snp" (set numplayed). Read the manual for more
828 information.
829
830 ---------------------------------------
831 0.2.1 (2005-08-15) "surreal experience"
832 ---------------------------------------
833
834 Here comes paraslash-0.2.1. It contains a couple of new features and,
835 surprise, only minor bug fixes.
836
837 - kill noisy mp3 debug message
838 - cleanup of the build system
839 - para_server and para_client directly use the crypto routines
840 of the openssl library rather than invoking the openssl command
841 line utitlity
842 - server/audiod: new option --user to switch to the given user
843 when invoked as root. Read the output of "para_server -h" for
844 more information.
845 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
846 status. Default: "para_audioc stat"
847 - sdl_gui: new option --pic_cmd to be used to download the picture.
848 Default: "para_client pic"
849 - audiod: 5 slots ought to be enough for everybody
850 - audiod: new status item: Uptime, kill hup command
851
852 ------------------------------------------
853 0.2.0 (2005-08-06) "distributed diffusion"
854 ------------------------------------------
855
856 After several month of increased development activity, paraslash-0.2.0
857 has arrived. It contains many new features and is much more
858 self-contained than the old 0.1.x series. Enjoy!
859
860
861 - para_server: fix hang on song change and crash on sighup.
862 Speed up mysql queries. The DIR_LIKE macro is gone.
863 - new executables: para_audiod, the local audio daemon that
864 starts playback (uses SCM_CREDENTIALS socket magic) and
865 para_audioc, the corresponding client.
866 - new executables: para_mp3dec/para_oggdec, two really teensy
867 decoders. para_mp3dec is based on libmad, para_oggdec requires
868 libvorbisfile.
869 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
870 they are now called para_send and para_recv respectively.
871 - documentation updates
872 - para_gui is themable. For now there is the default theme that
873 looks as before and the simple theme: blue and easy.
874 - gui: audio streaming is now handled by audiod. Time display shows
875 playback time rather than streaming time
876 - slider: update to libzmw-0.2.0
877 - para_krell: fix crash on server shutdown
878 - switch from gzip to bzip2
879
880 ----------------------------------------
881 0.1.7 (2005-04-18) "melting penetration"
882 ----------------------------------------
883
884 The main change in this release is clearly the oggvorbis rewrite,
885 but there are also lots of smaller changes. If you intend to use both
886 the mp3 and the ogg plugin, it is recommended to use software mixing,
887 e.g. the dmix plugin which is provided by ALSA.
888
889 - new executables: para_ovsend and para_ovrecv for sending/receiving
890 oggvorbis files via rtp. Requires the open rtp library. Get it at
891 http://www.linphone.org/ortp/
892 - rewrite of the ogg_vorbis core code
893 - configure detects libzmw and, if detected, includes
894 para_slider to the list of binaries to be built by make
895 - server stream writers read from their associated fifo rather
896 than from stdin
897 - slider: two new sliders, lastplayed and numplayed
898 - fix nasty double free bug which caused random segfaults in case of
899 mp3 files with invalid header information
900 - gui: new command line option: --stream_timeout=seconds to
901 deactivate a slot if it is idle for that many seconds (default=`5')
902 - diffstats
903
904 ---------------------------------------
905 0.1.6 (2005-03-05) "asymptotic balance"
906 ---------------------------------------
907
908 Only little user-visible changes in this release. Mainly bugfixes and
909 core code cleanup. This is probably the most stable version ever if you
910 stick to mp3...
911
912 - fix several memory leaks
913 - rename default name of mysql database from "music" to "paraslash".
914 Use para_server's --mysql_database option if you do not want to
915 rename your old database.
916 - rework ogg vorbis code
917 - make update command work on mysql servers with LOCAL_INFILE
918 disabled
919 - gui: improved stream I/O (slots)
920 - simplified audio format API
921 - para_pob_ogg is gone
922
923 ------------------------------------
924 0.1.5 (2004-12-31) "opaque eternity"
925 ------------------------------------
926
927 Let's slide gently into the new year.
928
929 - new: para_slider (not built automatically, type "make
930 para_slider" to build). A toy for those who always felt that
931 creating stream definitions is difficult. See screenshots,
932 README and FEATURES for more info.
933 - improved signal handling. Fixes server segfault on SIGHUP
934 for linux kernels newer than Aug 24 2004 and makes para_gui
935 race-free.
936 - reload database tool on SIGHUP
937 - improved help message for sl
938 - do not log "broken pipe" messages as errors. They are
939 perfectly ok.
940 - fix wrong error message on permission errors
941
942 -----------------------------------------
943 0.1.4 (2004-12-19) "tunneling transition"
944 -----------------------------------------
945
946 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
947 Hopefully, most of them got wiped out with this release. Some
948 enhancements went also in.
949
950 - improved error diagnostics for all commands
951 - stradd/picadd: overwrite previous contents if entry already
952 exists, rather than returning errors
953 - stradd: use current stream if invoked without args
954 - faster (and hopefully more stable) ogg-vorbis handling
955 - para_krell: reap children to avoid zombie-flooding in case
956 no server is running
957 - si: report also server pid
958 - server: don't busy-loop if dbtool reports only invalid files.
959 - gui: CTRL+C works again, fix stream_read command line option
960 - fix pic_add, hist
961 - fix mysql dbtool startup in case no database exists
962 - many small fixes and cleanups
963
964 ---------------------------------------
965 0.1.3: (2004-12-10) "vanishing inertia"
966 ---------------------------------------
967
968 Starting from this release, the database tools are integrated in the
969 server binary. This decreases server startup time, reduces code size
970 and speeds up database commands. However, the layout of the underlying
971 mysql database changed only slightly and 0.1.3 should be backwards
972 compatible in that respect.
973
974 Visible changes:
975
976 - If mysql is not detected at compile time, or fails to init
977 at runtime, fall back to the dopey database tool which should
978 always work.
979 - para_dbtool and dbtool.conf are gone. All mysql specific
980 options are read from server.conf and are prefixed by 'mysql_'.
981 - new command: cdt (change database tool)
982 - new command line option: dbtool (choose startup database tool)
983 - The name of current stream is now stored in the database,
984 so paraslash remembers its current stream when restarted.
985 - new command: csp (change stream and play)
986 - para_gui also reports current database tool and server uptime
987
988 -------------------------------------------
989 0.1.2: (2004-11-28) "spherical fluctuation"
990 -------------------------------------------
991
992 Point release before the big dbtool changes go in.
993
994 - dbtool: rename ca to cam (copy all meta data). It now also
995 copies numplayed and lastplayed time as well as the picture
996 id.
997 - fix endless-loop-bug caused by mp3 files with invalid header
998
999 -----------------------------------------
1000 0.1.1: (2004-11-05) "floating atmosphere"
1001 -----------------------------------------
1002
1003 - gkrellm plugin
1004 - new dbtool command: mbox. Browse your sound-file collection
1005 with your favorite mail reader.
1006 - several small fixes
1007
1008 -------------------------------------
1009 0.1.0: (2004-10-22) "rotating cortex"
1010 -------------------------------------
1011
1012 - fix logging bug for loglevel > VERBOSE
1013 - fix skip command
1014 - correct timings for vbr mp3s
1015 - modular audio format support
1016 - ogg-vorbis support (experimental)
1017 - new server option: autoplay
1018
1019 -----------------------------------------
1020 0.0.99: (2004-07-25) "harmonic deviation"
1021 -----------------------------------------
1022
1023 - rename projectname from icc to paraslash (play, archive, rate
1024 and stream large audio sets happily)
1025 - paraslash is no longer restricted to one particular audio
1026 streaming software
1027 - new dbtool commands (stradd, strq, strdel) for easy stream
1028 managment w/o configuration file. That obsoletes stream_defs
1029 file/config option for dbtool.
1030 - picadd accepts jpeg data from stdin
1031 - new server commands: ps (select previous stream), sc (song change)
1032 - new default pictures for sdl_gui
1033 - gui: new key_map option for binding commands and internal
1034 functions to arbitrary keys, nice help screen, rip out
1035 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1036 show silly logo on startup
1037 - new executables: para_fade for fading volume, para_dbadm for
1038 manipulating attributes
1039 - cdb adds _all_ tables to mysql database
1040 - revised and beautified documentation
1041 - sample dbtool rewritten in C
1042 - autoconf
1043
1044 ---------------------------------------------
1045 0.0.98: (2003-12-26) "incremental smoothness"
1046 ---------------------------------------------
1047
1048 - kick icecast in favour of poc. That removes some races and reduces
1049 core code considerably.
1050 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
