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