Merge branch 't/image-0.5'
[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 - New logo.
20
21 --------------------------------------
22 0.4.13 (2013-07-29) "spectral gravity"
23 --------------------------------------
24
25 One more 0.4.x release before the API-breaking changes for 0.5.0 go
26 in. The main features of this release are the ogg/opus audio format,
27 and UTF-8 support, but it includes also tons of other improvements
28 and fixes all over the place.
29
30 - New audio format: ogg/opus.
31 - UTF8 support for para_gui and the mp3 audio format handler.
32 - Scheduler improvements and fixes.
33 - The obsolete gettimeofday() function has been replaced
34 by clock_gettime() on systems which support it.
35 - Speed and usability improvements for para_gui.
36 - para_client now restores the fd flags of stdin and stdout
37 on shutdown.
38 - Improved manual pages.
39 - Consistent version strings for all executables.
40 - Reduced dependencies on generated files result in fewer
41 recompilations on changes.
42 - Performance improvements for the compress filter.
43 - Improved downloads web page.
44
45 -----------------------------------------
46 0.4.12 (2012-12-20) "volatile relativity"
47 -----------------------------------------
48 The new command line player, the resample filter, ALSA support for
49 para_fade, and the improved build system are the highlights of this
50 release which probably marks the end of the 0.4.x series.
51
52 - The afh receiver and the para_play executable.
53 - The resample filter: A sample rate converter based on
54 libsamplerate.
55 - The "versions" directory has been removed from the master
56 branch. The tarballs of the old releases are now available
57 in the new "releases" branch.
58 - Overhaul of the build system: All generated files are now
59 written to the "build" directory.
60 - The modular mixer API and the alsa mixer.
61 - Minor fixes for the osx writer.
62
63 --------------------------------------
64 0.4.11 (2012-07-20) "mutual diversity"
65 --------------------------------------
66
67 The major feature in this release is the new sideband API for
68 client-server communication. This API will be used exclusively starting
69 with 0.5.0, which breaks backward compatibility but allows to get rid
70 of quite some compatibility code. Other noteworthy changes include
71 decoder latency improvements and a long-standing bug fix for the
72 ALSA writer.
73
74 - Sideband connections: If both para_server and para_client
75 support this feature, data is sent as a multiplexed stream.
76 - The --no_default_filters option of para_filter has been
77 removed.
78 - Several fixes and latency improvements to various decoders.
79 - The ALSA writer now limits the prebuffer time to 500ms.
80 - Documentation improvements.
81 - Overhaul of the command_util.sh script.
82 - Fixes for some minor problems found by the clang analyzer.
83 - Compiles (almost) without warnings on gcc-3.
84 - Robustness improvements of the buffer tree code.
85
86 ------------------------------------------
87 0.4.10 (2012-03-30) "heterogeneous vacuum"
88 ------------------------------------------
89
90 Nothing earth-shaking in this release, but quite a few usability
91 improvements and the usual mix of cleanups and fixes.
92
93 - The --no_default_filters option of para_filter has been
94 deprecated. It still works but has no effect and will be
95 removed in the next version.
96 - para_gui now prints also the stderr output of the executing
97 command in the bottom window.
98 - Cleanup and consolidation of the various wrappers for
99 write(), writev(), send() and friends.
100 - The obscure error messages on mmap() failures have been
101 replaced by meaningful messages. This affects mainly
102 para_afh.
103 - para_audioc: Cleanups and memory leak fixes.
104 - Test 0004-server no longer fails if para_server is not
105 being built.
106 - New configure options: --with-id3tag-{headers,libs}.
107
108 -------------------------------------
109 0.4.9 (2011-12-06) "hybrid causality"
110 -------------------------------------
111
112 Support for another audio format, interactive mode for para_client
113 and para_audiod and many small improvements/fixes all over the place.
114
115 - Support for flac, the free lossless audio codec.
116 - Fix for an endless loop in the mp3 decoder for certain
117 (corrupt) mp3 files.
118 - When executed without specifying a command, para_client
119 and para_audioc start an interactive shell (requires
120 libreadline being installed). The interactive mode offers
121 full tab completion and command line history.
122 - autogen.sh now detects a distcc setup and adjusts the
123 parameter for the -j option of make accordingly.
124 - Shared memory areas are no longer restricted to 64K. We now
125 detect the maximal size of a shared memory area at runtime.
126 - cleanup of the internal uptime API.
127 - para_server prefaults the mmapped audio file to avoid
128 delays on slow media.
129 - A new test for the test-suite that exercises the
130 communication between para_server and para_audiod.
131 - The alsa writer eats up less CPU cycles when configured to
132 use the DMIX plugin.
133 - Simplified and unified receiver code.
134 - Makefile cleanups.
135 - Commands which print a list of matching audio files now
136 emit a meaningful error message if no audio file matched the
137 given pattern(s).
138
139 --------------------------------------
140 0.4.8 (2011-08-19) "nested assignment"
141 --------------------------------------
142
143 Gcrypt support, the overhauled osx writer and regex format specifiers
144 are the highlights of this release.
145
146 - support for libgcrypt as a drop-in replacement for openssl.
147 Run configure --enable-cryptolib=gcrypt to link against
148 libgcrypt. The two crypto implementations are compatible to
149 each other, i.e. a para_client executable linked against
150 gcrypt can connect to para_server linked against libssl
151 and vice versa.
152 - Rewrite of the osx writer (output plugin for Mac OS).
153 - audiod: The format specifier for receivers, filters and
154 writers is now treated as a regular expression. This allows
155 to replace 5 lines in the config file (one for each audio
156 format) by one single line. See the manual for details.
157 - The *.cmdline.[ch] files are no longer contained in the released
158 tarballs. This reduces the size of the tarballs but requires
159 gengetopt to build the tarball.
160 - Compiles cleanly also with llvm/clang.
161 - Corrupt mp3 files are handled more gracefully.
162 - The alsa writer uses poll fds instead of computing timeouts.
163 - Cleanup of the generic writer API.
164 - sched: Optimized zero timeouts.
165 - vss timeout cleanups.
166 - oggdec fixes and improvements.
167
168 --------------------------------------
169 0.4.7 (2011-06-01) "infinite rollback"
170 --------------------------------------
171
172 The new ao writer, support for ssh RSA keys and a couple of other
173 enhancements.
174
175 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
176 platforms through the libao audio library.
177 - Support for RSA keys generated with ssh-keygen.
178 - configure: improved options for ogg/vorbis/speex.
179 - The git version reported by --version always matches HEAD.
180 - The autogen script detects the number of processors and
181 runs a parallel make if possible.
182 - Major cleanup of the crypto API.
183 - Documentation updates.
184
185 ------------------------------------------
186 0.4.6 (2011-03-31) "deterministic entropy"
187 ------------------------------------------
188
189 Lots of ogg/vorbis improvements, the new test suite, enhancements
190 for para_gui and a fair amount of other bug fixes.
191
192 - For DCCP/OGG streams the audio file header is only sent once
193 at the beginning of the stream rather than periodically
194 every five seconds. This reduces network traffic and the
195 FEC group size.
196 - The vorbis comment header is replaced by an empty dummy header
197 before the header is sent over the network. This also results in
198 less network traffic and smaller FEC groups.
199 - The new "test" make target allows to perform some sanity checks prior
200 to installing the package.
201 - ogg timing fixes and performance improvements
202 - Scheduler improvements
203 - Proper exit codes for para_write
204 - para_gui: New option --theme to select a startup theme. Several
205 other improvements and fixes.
206 - aacdec error message cleanups
207 - simplified color error handling
208
209 --------------------------------------------
210 0.4.5 (2010-12-17) "symmetric randomization"
211 --------------------------------------------
212
213 Bug fixes, internal cleanups and variable-sized FEC slices.
214
215 - Contains a fix for an invalid-free-bug in the ogg audio format
216 handler code.
217 - Switching off the DCCP sender works again.
218 - para_audiod handles crashes of para_server more robustly.
219 - Internal scheduler and writer cleanups.
220 - Reduced latency due to variable-sized FEC slices.
221 - Improved documentation and error diagnostics.
222 - The build of para_server is now optional, allowing the build
223 to succeed in case libosl is not installed.
224
225 ------------------------------------------
226 0.4.4 (2010-08-06) "persistent regularity"
227 ------------------------------------------
228
229 Support for yet another audio format, para_write improvements and
230 bug fixes.
231
232 - Support for the speex codec.
233 - Support for sample formats other than 16 bit little endian.
234 - error2.h is now created by a perl script which speeds up configure
235 considerably.
236 - Fix a bug in the aac decoder which could lead to segfaults in
237 para_filter/para_audiod.
238 - Fixes for autoconf-2.66.
239
240 ----------------------------------------
241 0.4.3 (2010-07-05) "imaginary radiation"
242 ----------------------------------------
243
244 Many improvements for the DCCP and the UDP transport, the new user
245 manual and the usual mix of bug fixes and internal improvements.
246
247 - FEC support for the DCCP sender (Gerrit Renker). The new
248 --dccp_max_slice_size, --dccp_data_slices_per_group and
249 --dccp_slices_per_group options can be used to set the FEC
250 parameters for the DCCP transport.
251 - DNS lookups for UDP targets (Gerrit Renker).
252 - The new user manual replaces the README, README.afs, REQUIREMENTS
253 and INSTALL documents.
254 - Fix an end-of-file detection bug in the oggdec filter.
255 - The new nonblock API.
256 - Both options of the oggdec filter have been removed.
257 - New debug mode for the internal scheduler.
258
259 ------------------------------------------
260 0.4.2 (2010-04-23) "associative expansion"
261 ------------------------------------------
262
263 It's been some time since the last release, but finally here is
264 paraslash-0.4.2. The bulk of the changes comes from the new buffer
265 tree API, but there are changes all over the tree. Mainly performance
266 and usability improvements, but also quite some bug fixes.
267
268 - The new buffer tree API.
269 - DCCP: Support for CCID negotiation (Gerrit Renker).
270 - UDP robustness fixes.
271 - The --bufsize option for mp3dec is gone as it no longer makes sense
272 for the new buffer tree API.
273 - Fix audible buffer underruns for wma streams.
274 - The alsa writer no longer prints meaningless underrun durations.
275 - audiod: Defaults work also for udp streams. If no filter is
276 given for an audio format that is received via upd, fecdec is
277 automatically added as the first filter (along with the decoder).
278
279 ---------------------------------------
280 0.4.1 (2009-12-22) "concurrent horizon"
281 ---------------------------------------
282
283 Support for another audio format, minor feature enhancements and lots of bug
284 fixes. All fixes that have been accumulated in the maint branch (in particular
285 those mentionened in the 0.3.6 release notes) appear in this release as well.
286
287 - wma support.
288 - new afh option: --human to activate human-readable output.
289 - new server/audiod option: --log-timing to print timing information.
290 - build system improvements.
291 - source code documentation updates.
292
293 -------------------------------------
294 0.3.6 (2009-12-07) "cubic continuity"
295 -------------------------------------
296
297 Quite a few bugs have been found and fixed since 0.3.5, so here's
298 another 0.3.x release. No new features.
299
300 - Always check return value of malloc().
301 - ogg vorbis/FEC: Do not write garbage after the audio file header.
302 - exit if root privileges could not be dropped.
303 - FEC: Fix computation of extra slices.
304 - oss: Fix check for empty input buffer.
305 - Avoid buffer underruns due to filter chain output buffer constraints.
306 - server: Fix assignment of afs_pid.
307 - Don't panic if the afs database contains unknown audio formats.
308 - http/dccp: Do not send the audio file header twice.
309 - FEC: Timing improvements.
310
311 ----------------------------------------------
312 0.4.0 (2009-11-10) "simultaneous independence"
313 ----------------------------------------------
314
315 Two significant changes which require the new version number: The
316 improved authentication dialog and the fact that the database code
317 has been moved to a library, libosl. To use the new version, you have
318 to generate new RSA keys, see INSTALL for details. A shell script is
319 provided for conversion of the 0.3 database to the new 0.4 format.
320
321 - stronger crypto for client authentication
322 - the database code has been moved to a library
323 - improved status item handling
324 - cleanup of the build system
325 - The "-V" option now also prints the git version
326 - the new parser-friendly listing mode for the ls and stat commands
327 - mandatory rc4 encryption
328 - major audio format handler cleanups
329 - (id3,...) tags are no longer stored as a combined string in the database
330 - new mood methods: artist_matches, title_matches, comment_matches,
331 album_matches, year_maches, year.
332
333 --------------------------------------------
334 0.3.5 (2009-09-21) "symplectic separability"
335 --------------------------------------------
336
337 Full client support for *BSD Unixes, complete re-write of the ogg
338 vorbis audio format handler, various improvements all over the place
339 and the usual mix of bugfixes. This release marks the end of the 0.3
340 series if no serious problems show up.
341
342 - the new oss writer (supported on *BSD and Linux)
343 - rewrite of the ogg vorbis audio format handler. It's
344 recommended to replace the chunk tables of existing ogg
345 vorbis files in the afs database by re-adding these files
346 with "add -f".
347 - support for netmask subsets (Gerrit Renker)
348 - the new prebuffer filter
349 - improved signal handling
350 - variable fec output buffer size
351 - improved FEC timing fixes audible buffer underruns in UDP mode
352 - --log_color actually works
353 - new ls option: -d (print dates as seconds after the epoch)
354 - update to gengetopt 2.22.2
355 - support for RSA keys of size > 512 bits
356 - new option "mixer_channel" for para_fade
357
358 -----------------------------------------
359 0.3.4 (2009-05-07) "elliptic inheritance"
360 -----------------------------------------
361
362 The new udp sender, forward error correction, colored logs and various
363 other improvements. As the udp sender does not depend on any special
364 libraries, it is built unconditionally.
365
366 - The udp sender replaces the ortp sender. The new code uses forward
367 error correction to protect against packet losses. Many thanks to
368 Gerrit Renker for providing ipv6 support.
369 - The default port for udp streaming now defaults to 8000, like
370 for the http and the dccp senders/receivers.
371 - Loglevels are now specified as symbolic names, e.g.
372 "--loglevel info".
373 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
374 - para_server/para_audiod: Color support for log messages.
375 - new options for mp3dec: --ignore-crc, --bufsize
376 - new audiod option: --config-file.
377 - gengetopt cleanups.
378 - Improved help/man pages: The documentation of para_audiod,
379 para_recv, para_filter and para_write now also contains
380 all options of the available receivers/filters/writers. The
381 man page of para_fade contains a description of the different
382 modes of operation.
383 - More source code documentation.
384 - vss timing fixes.
385
386 --------------------------------------------
387 0.3.3 (2008-12-01) "axiomatic perspectivity"
388 --------------------------------------------
389
390 Internal code cleanups, bug fixes, improved tag handling and the new
391 amplification filter.
392
393 - para_server uses the generic scheduling code.
394 - overhaul of the virtual streaming system.
395 - mp3: id3 version 2 support via libid3tag (optional)
396 - ogg: vorbis comment support.
397 - aac meta info support.
398 - mp3 audio format handler cleanups.
399 - new filter: "amp" to amplify the amplitude of the audio stream
400 - new status item/database entry: amplification. It is
401 used by the amp filter to pre-amplify the audio stream.
402 - fix a close-without-open bug in para_write.
403 - fix a bug in com_init() which was introduced in 0.3.2.
404 - better error diagnostics for para_client.
405
406 -----------------------------------------
407 0.3.2 (2008-04-11) "probabilistic parity"
408 -----------------------------------------
409
410 The new para_afh executable, scheduling and documentation improvements.
411
412 - new ls option: -lc (list chunk table)
413 - new executable: para_afh, the stand-alone audio file handler tool
414 - afs commands can send output more than SHMMAX (32MB on Linux). This
415 also reduces the memory usage of commands that produce large amounts
416 of output.
417 - major scheduler and audiod cleanups.
418 - more detailed and much nicer man pages.
419
420 ---------------------------------------
421 0.3.1 (2008-02-23) "liquid interaction"
422 ---------------------------------------
423
424 A mix of cleanups, bug fixes, improvements, and some new features. No
425 significant changes to the new database (osl) code, which is generally
426 a good sign.
427
428 - Share some similar/duplicate code between the http and the
429 dccp sender.
430 - Generic access control lists for paraslash senders.
431 - dccp sender: Access control lists, connection limiting and support
432 for the allow,deny,on,off,help sender commands.
433 - The default dccp port changed from 5001 to 8000 (suggested by
434 Gerrit Renker).
435 - para_server starts even if not all public keys could be loaded.
436 - Audiod performance improvements.
437 - fix a bug in the "off" command of the http sender.
438 - fix some fd and memory leaks.
439 - Update to gengetopt-2.22.
440
441 -------------------------------------
442 0.3.0 (2008-01-12) "solar saturation"
443 -------------------------------------
444
445 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
446
447
448 Usually one might expect lots of new features AND a big increase in size
449 for a major release like this.
450
451 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
452 ever. The decrease in size is mostly due to the removal of some
453 graphical tools (which were only quick hacks anyway). But also the
454 fact that the mysql code is gone cuts down the size a bit.
455
456 Being independent of mysql comes at a cost: The fact that paraslash
457 now contains its own database (the object storage layer, osl) increases
458 the (stripped) binary size of para_server by ~50K on i386.
459
460 - no more restrictions on unique basenames.
461 - independent of mysql: The new self-contained object
462 storage layer (osl) replaces the mysql database.
463 - New executable para_fsck: Check integrity of osl tables.
464 - Lyrics support.
465 - Reliable audio file move/rename detection.
466 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
467 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
468 Solaris (sparc64).
469 - the new osl-based audio file selector (afs) replaces the random,
470 the playlist and the mysql selector of paraslash-0.2.x.
471 - IPv6 support (thanks to Gerrit Renker).
472 - paraslash-0.2.x streams are now called "moods". Writing
473 0.3.x-mood definitions should be both easier and more
474 powerful than writing 0.2.x-stream definitions.
475 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
476 been removed. The world is a better place without them. However,
477 para_gui is still there.
478 - afs tracks audio file selection also in playlist mode.
479 - few easy-to-use afs commands replace the many not-so-easy-to-use
480 mysql commands (and are available also in playlist mode).
481 - Improved error subsystem.
482 - The earth-shaking new logo.
483
484 -----------------------------------------
485 0.2.17 (2007-11-20) "isotropic threshold"
486 -----------------------------------------
487
488 Mainly bugfixes and cleanups in this version which marks the end of
489 the 0.2.x series if no serious bugs show up after the release.
490
491 - mysql_selector: fix a locking bug.
492 - universal chunk queueing.
493 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
494 to Gerrit Renker).
495 - be more carful wrt. signed vs. unsigned argument passing.
496 - cleanup error.h and fix some references to invalid error
497 codes.
498 - update to gengetopt-2.21.
499 - update to ortp-0.13.1.
500 - autoconf: extend checks for headers, library functions and
501 compiler characteristics.
502 - Fix streaming of large mp3 files.
503 - Fix an off-by-one bug in playlist handling.
504
505 --------------------------------------
506 0.2.16 (2007-04-05) "neural discharge"
507 --------------------------------------
508
509 The main change in this release is the major audio format handler
510 cleanup which removes some similar/duplicate code and makes it easier
511 to implement plugins for other audio formats. Of course, the usual mix
512 of other improvements/changes/bugfixes also made it into the release.
513
514 - simplified audio format handlers (most of the handling functions
515 were moved one layer up to the virtual streaming system).
516 - para_server uses mmap to read audio files
517 - repositioning of mp3 streams is much faster, in particular for
518 jumping near the end of large mp3 files.
519 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
520 and AFS_WRITE.
521 - fix a bug in para_filter that caused decoding of aac files
522 to start only after a few seconds.
523 - fix osx_writer hangs
524 - simplified dccp code (thanks to Gerrit Renker)
525 - the compress filter works also on big endian systems (ppc)
526
527 -----------------------------------------
528 0.2.15 (2007-02-16) "inductive resonance"
529 -----------------------------------------
530
531 Minor improvements, more documentation and a bunch of bug fixes.
532
533 - para_server: The server.users file is only read once on server
534 startup rather than for each connection
535 - mp3dec: Fix decoding of corrupt mp3 files
536 - afs (audio file sender) is now called vss (virtual streaming
537 system). Consequently, the permission flags specified in
538 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
539 become VSS_READ and VSS_WRITE respectively.
540 - para_audiod/para_filter: Fix a bug that caused the last chunk
541 of audio data not being written under certain circumstances
542 - audiod: compute the difference of server time and local time
543 correctly
544 - para_server/para_audiod: Fix some memory leaks
545 - documentation improvements
546 - configure.ac: fix checks for para_krell
547 - new man pages
548
549 -------------------------------------------
550 0.2.14 (2006-10-15) "transient singularity"
551 -------------------------------------------
552
553 The only major enhancement of this version is the osx writer which completes
554 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
555 until now for reasons beyond the scope of this changelog entry.
556
557 - new output plugin for Mac Os: the osx writer
558 - rename configure command line options from --enable-xxx-headers to
559 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
560 - configure: new command line options: --with-mad-headers,
561 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
562 - some robustness fixes
563 - dymamic audio format recognition for audiod
564 - para_server: new command line option: --autoplay_delay
565 - para_audiod: new command line option: --clock_diff_count
566
567 ---------------------------------------
568 0.2.13 (2006-07-14) "sonic convolution"
569 ---------------------------------------
570
571 A bunch of new features and core changes.
572
573 - the new paraslash scheduler, short and sweet.
574 - Support for m4a/mp4 files via the new aac audio format
575 handler/filter (requires libfaad).
576 - each writer has its own command line parser, just like
577 para_recv and para_filter.
578 - para_client and para_audioc use the error subsystem
579 - writers are integrated in para_audiod (currently linux-only)
580 - para_client is integrated in para_audiod
581 - random/playlist selector: improved info strings
582 - new audiod commands: tasks, kill
583 - update to libortp-0.10.1
584 - para_fade: wake time defaults to 8 hours from now
585 - update to autoconf-2.60
586
587 ------------------------------------------
588 0.2.12 (2006-05-12) "oriented abstraction"
589 ------------------------------------------
590
591 Many user-visible changes in this release and lots of new
592 features:
593
594
595 - the new optional dccp sender/receiver. It uses the datagram
596 congestion control protocol. You'll need a fairly new kernel
597 for this.
598 - paraslash works on Mac OS X (thanks to Gerd Becker)
599 - para_play renamed to para_write
600 - modular output plugin design (writers) for para_write
601 - new file_writer output plugin for para_write
602 - compress filter speed improvements
603 - update to libortp-0.9.1
604 - update to gengetopt-2.17rc
605 - para_client no longer depends on libreadline (as the
606 code for the interactive mode was removed).
607 - gcc-2-95 is no longer a supported compiler. It may still
608 work, but it gets no more testing.
609 - the tarball no longer contains the screenshot images which
610 reduces its size quite a bit.
611 - configure: new command line options: --enable-mysql-headers
612 and --enable-mysql-libs
613
614 ------------------------------------
615 0.2.11 (2006-03-11) "atomic duality"
616 ------------------------------------
617
618 Here it is, the first paraslash release developed with git. There
619 are fairly many user-visible changes in this release. As two out of
620 the three "database tools" of paraslash don't use a database at all,
621 they are now called "audio file selectors" instead.
622
623
624 - the cdt command (change database tool) becomes chs (change
625 selector)
626 - no more colon separators: The syntax of some options of
627 para_audiod and para_filter have changed. Use --help for
628 more info (and some examples).
629 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
630 - switch from cvs to git (should've done that earlier)
631 - the new ipc subsystem
632 - new audio file selector: playlist
633 - para_server: the dopey selector is now called "random",
634 and is the default selector. Use the --selector option to
635 choose another selector at startup, or the chs command to
636 change the selector at runtime.
637 - X86_64 fixes (thanks to Steffen Klassert)
638 - para_play fixes
639
640 --------------------------------------
641 0.2.10 (2006-02-17) "cyclic attractor"
642 --------------------------------------
643
644 Huge documentation update, a scrollable window for para_gui, ortp
645 improvements, and of course many small fixes not mentioned here.
646 The diffstat below is rather misleading as most insertions are due
647 to the new source documentation.
648
649 - autoconf cleanup
650 - para_server also uses the new error subsystem
651 - lots of new documentation (UTSL)
652 - gui improvements:
653 - keysyms for cursor keys and for next/previous page keys
654 - scrollable output window
655 - new internal commands: scroll up/down, page up/down
656 - fix color of command output.
657 - ortp: the --chunk_time and --header flags are no longer needed
658 for para_recv/para_audiod as this information is now encoded in
659 each rtp packet sent by para_server.
660
661 -------------------------------------------
662 0.2.9 (2006-01-24) "progressive turbulence"
663 -------------------------------------------
664
665 Internal audiod receivers/filters, the new error subsystem and
666 a lot of small improvements.
667
668 - para_recv and para_filter are integrated into the para_audiod
669 binary, i.e. audiod no longer spawns a new process for
670 each receiver/filter. As para_recv and para_filter might be
671 useful as standalone programs, they still get built (linked
672 against the same object files that are also used for audiod).
673 - further ortp timing improvements should reduce the CPU usage
674 of the ortp receiver.
675 - improved audio grabbing. The 'grab' command of para_audiod
676 has its own set of command line options. Read the output of
677 "para_audioc help grab" for more info.
678 - oggdec: configurable input prebuffer size.
679 - the new error subsystem gives better error diagnostics
680 and reduces code size.
681
682 -----------------------------------------
683 0.2.8 (2006-01-02) "dynamic accumulation"
684 -----------------------------------------
685
686 The new modular filter design and the para_play-hangs bugfix.
687
688 - new executable: para_filter. It combines para_mp3dec,
689 para_oggdec and para_compress. It also adds a further filter
690 type, wav, that just inserts a wave header at the desired point
691 of the filter chain. All 'piping' is done in-memory (i.e. no
692 read/write operations are used).
693 - para_play: fix a stupid bug that caused it to hang under
694 certain circumstances.
695
696 -------------------------------------------
697 0.2.7 (2006-12-27) "transparent invariance"
698 -------------------------------------------
699
700 Not many user-visible changes but a fair amount of internal improvements.
701
702
703 - The http sender buffers data if it can not be sent
704 out immediately (because the socket is not writable). This
705 should prevent para_server from shutting down the connection
706 too early on a loaded network.
707 - para_play also prebuffers data if it is told to start at a
708 future time by the --start_time option.
709 - The return of para_recv: It combines para_ortp_recv and
710 para_http_recv. Use the --receiver option to switch between
711 the two. para_recv builds without libortp, but contains
712 only the http receiver in this case.
713 - update to ortp 0.8.1. As this ortp release contains incompatible
714 changes, para_recv-0.2.7 won't link against older ortp libs.
715 - improved ortp timings.
716 - use of gcc-extensions that #define away for non-gcc and
717 gcc < 3.0.
718
719 -------------------------------------------
720 0.2.6 (2005-10-29) "recursive compensation"
721 -------------------------------------------
722
723 Transparent session encryption (uses openssl's Alleged RC4 cipher),
724 the internal find command and several other improvements and cleanups.
725
726 - Encrypt the session if encryption is requested by the client
727 (default for para_client 0.2.6). This is backwards
728 compatible, so older clients can still connect to para_server
729 0.2.6. Use the new client option --plain to request an
730 uncrypted session (off by default, must be set to on in
731 order to connect to para_server 0.2.x with 0 <= x <= 5).
732 - para_server uses an internal function to locate audio files
733 rather than calling find(1). The server option
734 --mysql_audio_file_dir replaces --mysql_find_cmd.
735 - documentation update
736 - man pages
737 - header file cleanup
738 - para_client code cleanup
739 - para_gui: faster display of output of display commands
740
741 ------------------------------------------
742 0.2.5 (2005-10-13) "aggressive resolution"
743 ------------------------------------------
744
745 This release adds internal senders, i.e. no more external programs are
746 spawned for sending out the audio data. There are two different senders
747 available: The http sender and the ortp sender (former para_send which
748 is no longer needed).
749
750 The new sender code has a plugin-like design so it can be easily
751 extended should there be be any future need for supporting another
752 network streaming protocol. All senders are completely independent of
753 each other. In particular, the http and the ortp sender can operate
754 in parallel.
755
756 - new server command: sender to control senders at runtime.
757 Read the output of "para_server -h" and "para_client help
758 sender" for more information.
759 - para_recv renamed to para_ortp_recv
760 - new executable: para_http_recv, a simple command line
761 http receiver.
762 - major afs/mp3/ogg code simplifications due to internal
763 senders.
764 - ogg timing improvements
765 - fix several minor memory leaks (found by valgrind)
766 - empty stream definitions work again
767 - com_ne(): ignore errors on remove
768 - audiod: fix segfault on server restart
769
770 ---------------------------------------
771 0.2.4 (2005-09-21) "toxic anticipation"
772 ---------------------------------------
773
774 Several small improvements, fixes and the new grab command.
775
776 - audiod:
777 - new command: "grab" to grab the output of the stream reader
778 or any filters. Read the output of "para_audioc help grab"
779 for more information.
780 - fix memory leak
781 - code cleanup
782 - audioc: new command line option: --bufsize to specify a
783 buffer size different from the default size 8192.
784 - improved error diagnostics for para_play.
785 - new configure option: --enable-ssldir so search for openssl in
786 non-standard places
787 - sdl_gui: Make it look nice again for 1024x768
788 - server: report total size of memory allocated with sbrk by malloc,
789 new command line option: --announce_time
790
791 -----------------------------------------
792 0.2.3 (2005-09-01) "hydrophilic movement"
793 -----------------------------------------
794
795 Two new executables and major feature enhancements.
796
797 - audiod filters: It is now possible to specify arbitrary many
798 (including none) filters for each supported audio
799 format. This can be used e.g. for normalizing volume,
800 transforming or grabbing the audio stream, or for using
801 visualizers. Read the output of "para_audiod -h" for the
802 syntax of the new --filter_cmd option.
803 - new executable: para_play, a tiny alsa player. It
804 can play wave files or raw pcm (16 bit little endian)
805 from stdin.
806 - new executable: para_compress, a dynamic range compressor
807 intended to keep audio output at a consistent volume. Derived
808 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
809 - audiod: New option: --stream_delay. This can be used in
810 a local network to syncronize the audio output of all
811 clients that play the same stream.
812
813 ------------------------------------------
814 0.2.2 (2005-08-19) "tangential excitation"
815 ------------------------------------------
816
817 Mostly internal changes in this release, but also some new commands
818 for the mysql database tool.
819
820 - cleanup exec.c, fix para_exec bug
821 - compile time loglevel (log messages below the given level
822 won't be compiled in, which reduces the size of the
823 resulting binaries)
824 - new log macros that shorten the size of the source code.
825 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
826 to send only zeros. With this workaround, para_audioc works
827 again.
828 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
829 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
830 (new entry), "snp" (set numplayed). Read the manual for more
831 information.
832
833 ---------------------------------------
834 0.2.1 (2005-08-15) "surreal experience"
835 ---------------------------------------
836
837 Here comes paraslash-0.2.1. It contains a couple of new features and,
838 surprise, only minor bug fixes.
839
840 - kill noisy mp3 debug message
841 - cleanup of the build system
842 - para_server and para_client directly use the crypto routines
843 of the openssl library rather than invoking the openssl command
844 line utitlity
845 - server/audiod: new option --user to switch to the given user
846 when invoked as root. Read the output of "para_server -h" for
847 more information.
848 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
849 status. Default: "para_audioc stat"
850 - sdl_gui: new option --pic_cmd to be used to download the picture.
851 Default: "para_client pic"
852 - audiod: 5 slots ought to be enough for everybody
853 - audiod: new status item: Uptime, kill hup command
854
855 ------------------------------------------
856 0.2.0 (2005-08-06) "distributed diffusion"
857 ------------------------------------------
858
859 After several month of increased development activity, paraslash-0.2.0
860 has arrived. It contains many new features and is much more
861 self-contained than the old 0.1.x series. Enjoy!
862
863
864 - para_server: fix hang on song change and crash on sighup.
865 Speed up mysql queries. The DIR_LIKE macro is gone.
866 - new executables: para_audiod, the local audio daemon that
867 starts playback (uses SCM_CREDENTIALS socket magic) and
868 para_audioc, the corresponding client.
869 - new executables: para_mp3dec/para_oggdec, two really teensy
870 decoders. para_mp3dec is based on libmad, para_oggdec requires
871 libvorbisfile.
872 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
873 they are now called para_send and para_recv respectively.
874 - documentation updates
875 - para_gui is themable. For now there is the default theme that
876 looks as before and the simple theme: blue and easy.
877 - gui: audio streaming is now handled by audiod. Time display shows
878 playback time rather than streaming time
879 - slider: update to libzmw-0.2.0
880 - para_krell: fix crash on server shutdown
881 - switch from gzip to bzip2
882
883 ----------------------------------------
884 0.1.7 (2005-04-18) "melting penetration"
885 ----------------------------------------
886
887 The main change in this release is clearly the oggvorbis rewrite,
888 but there are also lots of smaller changes. If you intend to use both
889 the mp3 and the ogg plugin, it is recommended to use software mixing,
890 e.g. the dmix plugin which is provided by ALSA.
891
892 - new executables: para_ovsend and para_ovrecv for sending/receiving
893 oggvorbis files via rtp. Requires the open rtp library. Get it at
894 http://www.linphone.org/ortp/
895 - rewrite of the ogg_vorbis core code
896 - configure detects libzmw and, if detected, includes
897 para_slider to the list of binaries to be built by make
898 - server stream writers read from their associated fifo rather
899 than from stdin
900 - slider: two new sliders, lastplayed and numplayed
901 - fix nasty double free bug which caused random segfaults in case of
902 mp3 files with invalid header information
903 - gui: new command line option: --stream_timeout=seconds to
904 deactivate a slot if it is idle for that many seconds (default=`5')
905 - diffstats
906
907 ---------------------------------------
908 0.1.6 (2005-03-05) "asymptotic balance"
909 ---------------------------------------
910
911 Only little user-visible changes in this release. Mainly bugfixes and
912 core code cleanup. This is probably the most stable version ever if you
913 stick to mp3...
914
915 - fix several memory leaks
916 - rename default name of mysql database from "music" to "paraslash".
917 Use para_server's --mysql_database option if you do not want to
918 rename your old database.
919 - rework ogg vorbis code
920 - make update command work on mysql servers with LOCAL_INFILE
921 disabled
922 - gui: improved stream I/O (slots)
923 - simplified audio format API
924 - para_pob_ogg is gone
925
926 ------------------------------------
927 0.1.5 (2004-12-31) "opaque eternity"
928 ------------------------------------
929
930 Let's slide gently into the new year.
931
932 - new: para_slider (not built automatically, type "make
933 para_slider" to build). A toy for those who always felt that
934 creating stream definitions is difficult. See screenshots,
935 README and FEATURES for more info.
936 - improved signal handling. Fixes server segfault on SIGHUP
937 for linux kernels newer than Aug 24 2004 and makes para_gui
938 race-free.
939 - reload database tool on SIGHUP
940 - improved help message for sl
941 - do not log "broken pipe" messages as errors. They are
942 perfectly ok.
943 - fix wrong error message on permission errors
944
945 -----------------------------------------
946 0.1.4 (2004-12-19) "tunneling transition"
947 -----------------------------------------
948
949 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
950 Hopefully, most of them got wiped out with this release. Some
951 enhancements went also in.
952
953 - improved error diagnostics for all commands
954 - stradd/picadd: overwrite previous contents if entry already
955 exists, rather than returning errors
956 - stradd: use current stream if invoked without args
957 - faster (and hopefully more stable) ogg-vorbis handling
958 - para_krell: reap children to avoid zombie-flooding in case
959 no server is running
960 - si: report also server pid
961 - server: don't busy-loop if dbtool reports only invalid files.
962 - gui: CTRL+C works again, fix stream_read command line option
963 - fix pic_add, hist
964 - fix mysql dbtool startup in case no database exists
965 - many small fixes and cleanups
966
967 ---------------------------------------
968 0.1.3: (2004-12-10) "vanishing inertia"
969 ---------------------------------------
970
971 Starting from this release, the database tools are integrated in the
972 server binary. This decreases server startup time, reduces code size
973 and speeds up database commands. However, the layout of the underlying
974 mysql database changed only slightly and 0.1.3 should be backwards
975 compatible in that respect.
976
977 Visible changes:
978
979 - If mysql is not detected at compile time, or fails to init
980 at runtime, fall back to the dopey database tool which should
981 always work.
982 - para_dbtool and dbtool.conf are gone. All mysql specific
983 options are read from server.conf and are prefixed by 'mysql_'.
984 - new command: cdt (change database tool)
985 - new command line option: dbtool (choose startup database tool)
986 - The name of current stream is now stored in the database,
987 so paraslash remembers its current stream when restarted.
988 - new command: csp (change stream and play)
989 - para_gui also reports current database tool and server uptime
990
991 -------------------------------------------
992 0.1.2: (2004-11-28) "spherical fluctuation"
993 -------------------------------------------
994
995 Point release before the big dbtool changes go in.
996
997 - dbtool: rename ca to cam (copy all meta data). It now also
998 copies numplayed and lastplayed time as well as the picture
999 id.
1000 - fix endless-loop-bug caused by mp3 files with invalid header
1001
1002 -----------------------------------------
1003 0.1.1: (2004-11-05) "floating atmosphere"
1004 -----------------------------------------
1005
1006 - gkrellm plugin
1007 - new dbtool command: mbox. Browse your sound-file collection
1008 with your favorite mail reader.
1009 - several small fixes
1010
1011 -------------------------------------
1012 0.1.0: (2004-10-22) "rotating cortex"
1013 -------------------------------------
1014
1015 - fix logging bug for loglevel > VERBOSE
1016 - fix skip command
1017 - correct timings for vbr mp3s
1018 - modular audio format support
1019 - ogg-vorbis support (experimental)
1020 - new server option: autoplay
1021
1022 -----------------------------------------
1023 0.0.99: (2004-07-25) "harmonic deviation"
1024 -----------------------------------------
1025
1026 - rename projectname from icc to paraslash (play, archive, rate
1027 and stream large audio sets happily)
1028 - paraslash is no longer restricted to one particular audio
1029 streaming software
1030 - new dbtool commands (stradd, strq, strdel) for easy stream
1031 managment w/o configuration file. That obsoletes stream_defs
1032 file/config option for dbtool.
1033 - picadd accepts jpeg data from stdin
1034 - new server commands: ps (select previous stream), sc (song change)
1035 - new default pictures for sdl_gui
1036 - gui: new key_map option for binding commands and internal
1037 functions to arbitrary keys, nice help screen, rip out
1038 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1039 show silly logo on startup
1040 - new executables: para_fade for fading volume, para_dbadm for
1041 manipulating attributes
1042 - cdb adds _all_ tables to mysql database
1043 - revised and beautified documentation
1044 - sample dbtool rewritten in C
1045 - autoconf
1046
1047 ---------------------------------------------
1048 0.0.98: (2003-12-26) "incremental smoothness"
1049 ---------------------------------------------
1050
