[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
13 --------------------------------------
14 0.4.13 (2013-07-29) "spectral gravity"
15 --------------------------------------
16
17 One more 0.4.x release before the API-breaking changes for 0.5.0 go
18 in. The main features of this release are the ogg/opus audio format,
19 and UTF-8 support, but it includes also tons of other improvements
20 and fixes all over the place.
21
22 - New audio format: ogg/opus.
23 - UTF8 support for para_gui and the mp3 audio format handler.
24 - Scheduler improvements and fixes.
25 - The obsolete gettimeofday() function has been replaced
26 by clock_gettime() on systems which support it.
27 - Speed and usability improvements for para_gui.
28 - para_client now restores the fd flags of stdin and stdout
29 on shutdown.
30 - Improved manual pages.
31 - Consistent version strings for all executables.
32 - Reduced dependencies on generated files result in fewer
33 recompilations on changes.
34 - Performance improvements for the compress filter.
35 - Improved downloads web page.
36
37 -----------------------------------------
38 0.4.12 (2012-12-20) "volatile relativity"
39 -----------------------------------------
40 The new command line player, the resample filter, ALSA support for
41 para_fade, and the improved build system are the highlights of this
42 release which probably marks the end of the 0.4.x series.
43
44 - The afh receiver and the para_play executable.
45 - The resample filter: A sample rate converter based on
46 libsamplerate.
47 - The "versions" directory has been removed from the master
48 branch. The tarballs of the old releases are now available
49 in the new "releases" branch.
50 - Overhaul of the build system: All generated files are now
51 written to the "build" directory.
52 - The modular mixer API and the alsa mixer.
53 - Minor fixes for the osx writer.
54
55 --------------------------------------
56 0.4.11 (2012-07-20) "mutual diversity"
57 --------------------------------------
58
59 The major feature in this release is the new sideband API for
60 client-server communication. This API will be used exclusively starting
61 with 0.5.0, which breaks backward compatibility but allows to get rid
62 of quite some compatibility code. Other noteworthy changes include
63 decoder latency improvements and a long-standing bug fix for the
64 ALSA writer.
65
66 - Sideband connections: If both para_server and para_client
67 support this feature, data is sent as a multiplexed stream.
68 - The --no_default_filters option of para_filter has been
69 removed.
70 - Several fixes and latency improvements to various decoders.
71 - The ALSA writer now limits the prebuffer time to 500ms.
72 - Documentation improvements.
73 - Overhaul of the command_util.sh script.
74 - Fixes for some minor problems found by the clang analyzer.
75 - Compiles (almost) without warnings on gcc-3.
76 - Robustness improvements of the buffer tree code.
77
78 ------------------------------------------
79 0.4.10 (2012-03-30) "heterogeneous vacuum"
80 ------------------------------------------
81
82 Nothing earth-shaking in this release, but quite a few usability
83 improvements and the usual mix of cleanups and fixes.
84
85 - The --no_default_filters option of para_filter has been
86 deprecated. It still works but has no effect and will be
87 removed in the next version.
88 - para_gui now prints also the stderr output of the executing
89 command in the bottom window.
90 - Cleanup and consolidation of the various wrappers for
91 write(), writev(), send() and friends.
92 - The obscure error messages on mmap() failures have been
93 replaced by meaningful messages. This affects mainly
94 para_afh.
95 - para_audioc: Cleanups and memory leak fixes.
96 - Test 0004-server no longer fails if para_server is not
97 being built.
98 - New configure options: --with-id3tag-{headers,libs}.
99
100 -------------------------------------
101 0.4.9 (2011-12-06) "hybrid causality"
102 -------------------------------------
103
104 Support for another audio format, interactive mode for para_client
105 and para_audiod and many small improvements/fixes all over the place.
106
107 - Support for flac, the free lossless audio codec.
108 - Fix for an endless loop in the mp3 decoder for certain
109 (corrupt) mp3 files.
110 - When executed without specifying a command, para_client
111 and para_audioc start an interactive shell (requires
112 libreadline being installed). The interactive mode offers
113 full tab completion and command line history.
114 - autogen.sh now detects a distcc setup and adjusts the
115 parameter for the -j option of make accordingly.
116 - Shared memory areas are no longer restricted to 64K. We now
117 detect the maximal size of a shared memory area at runtime.
118 - cleanup of the internal uptime API.
119 - para_server prefaults the mmapped audio file to avoid
120 delays on slow media.
121 - A new test for the test-suite that exercises the
122 communication between para_server and para_audiod.
123 - The alsa writer eats up less CPU cycles when configured to
124 use the DMIX plugin.
125 - Simplified and unified receiver code.
126 - Makefile cleanups.
127 - Commands which print a list of matching audio files now
128 emit a meaningful error message if no audio file matched the
129 given pattern(s).
130
131 --------------------------------------
132 0.4.8 (2011-08-19) "nested assignment"
133 --------------------------------------
134
135 Gcrypt support, the overhauled osx writer and regex format specifiers
136 are the highlights of this release.
137
138 - support for libgcrypt as a drop-in replacement for openssl.
139 Run configure --enable-cryptolib=gcrypt to link against
140 libgcrypt. The two crypto implementations are compatible to
141 each other, i.e. a para_client executable linked against
142 gcrypt can connect to para_server linked against libssl
143 and vice versa.
144 - Rewrite of the osx writer (output plugin for Mac OS).
145 - audiod: The format specifier for receivers, filters and
146 writers is now treated as a regular expression. This allows
147 to replace 5 lines in the config file (one for each audio
148 format) by one single line. See the manual for details.
149 - The *.cmdline.[ch] files are no longer contained in the released
150 tarballs. This reduces the size of the tarballs but requires
151 gengetopt to build the tarball.
152 - Compiles cleanly also with llvm/clang.
153 - Corrupt mp3 files are handled more gracefully.
154 - The alsa writer uses poll fds instead of computing timeouts.
155 - Cleanup of the generic writer API.
156 - sched: Optimized zero timeouts.
157 - vss timeout cleanups.
158 - oggdec fixes and improvements.
159
160 --------------------------------------
161 0.4.7 (2011-06-01) "infinite rollback"
162 --------------------------------------
163
164 The new ao writer, support for ssh RSA keys and a couple of other
165 enhancements.
166
167 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
168 platforms through the libao audio library.
169 - Support for RSA keys generated with ssh-keygen.
170 - configure: improved options for ogg/vorbis/speex.
171 - The git version reported by --version always matches HEAD.
172 - The autogen script detects the number of processors and
173 runs a parallel make if possible.
174 - Major cleanup of the crypto API.
175 - Documentation updates.
176
177 ------------------------------------------
178 0.4.6 (2011-03-31) "deterministic entropy"
179 ------------------------------------------
180
181 Lots of ogg/vorbis improvements, the new test suite, enhancements
182 for para_gui and a fair amount of other bug fixes.
183
184 - For DCCP/OGG streams the audio file header is only sent once
185 at the beginning of the stream rather than periodically
186 every five seconds. This reduces network traffic and the
187 FEC group size.
188 - The vorbis comment header is replaced by an empty dummy header
189 before the header is sent over the network. This also results in
190 less network traffic and smaller FEC groups.
191 - The new "test" make target allows to perform some sanity checks prior
192 to installing the package.
193 - ogg timing fixes and performance improvements
194 - Scheduler improvements
195 - Proper exit codes for para_write
196 - para_gui: New option --theme to select a startup theme. Several
197 other improvements and fixes.
198 - aacdec error message cleanups
199 - simplified color error handling
200
201 --------------------------------------------
202 0.4.5 (2010-12-17) "symmetric randomization"
203 --------------------------------------------
204
205 Bug fixes, internal cleanups and variable-sized FEC slices.
206
207 - Contains a fix for an invalid-free-bug in the ogg audio format
208 handler code.
209 - Switching off the DCCP sender works again.
210 - para_audiod handles crashes of para_server more robustly.
211 - Internal scheduler and writer cleanups.
212 - Reduced latency due to variable-sized FEC slices.
213 - Improved documentation and error diagnostics.
214 - The build of para_server is now optional, allowing the build
215 to succeed in case libosl is not installed.
216
217 ------------------------------------------
218 0.4.4 (2010-08-06) "persistent regularity"
219 ------------------------------------------
220
221 Support for yet another audio format, para_write improvements and
222 bug fixes.
223
224 - Support for the speex codec.
225 - Support for sample formats other than 16 bit little endian.
226 - error2.h is now created by a perl script which speeds up configure
227 considerably.
228 - Fix a bug in the aac decoder which could lead to segfaults in
229 para_filter/para_audiod.
230 - Fixes for autoconf-2.66.
231
232 ----------------------------------------
233 0.4.3 (2010-07-05) "imaginary radiation"
234 ----------------------------------------
235
236 Many improvements for the DCCP and the UDP transport, the new user
237 manual and the usual mix of bug fixes and internal improvements.
238
239 - FEC support for the DCCP sender (Gerrit Renker). The new
240 --dccp_max_slice_size, --dccp_data_slices_per_group and
241 --dccp_slices_per_group options can be used to set the FEC
242 parameters for the DCCP transport.
243 - DNS lookups for UDP targets (Gerrit Renker).
244 - The new user manual replaces the README, README.afs, REQUIREMENTS
245 and INSTALL documents.
246 - Fix an end-of-file detection bug in the oggdec filter.
247 - The new nonblock API.
248 - Both options of the oggdec filter have been removed.
249 - New debug mode for the internal scheduler.
250
251 ------------------------------------------
252 0.4.2 (2010-04-23) "associative expansion"
253 ------------------------------------------
254
255 It's been some time since the last release, but finally here is
256 paraslash-0.4.2. The bulk of the changes comes from the new buffer
257 tree API, but there are changes all over the tree. Mainly performance
258 and usability improvements, but also quite some bug fixes.
259
260 - The new buffer tree API.
261 - DCCP: Support for CCID negotiation (Gerrit Renker).
262 - UDP robustness fixes.
263 - The --bufsize option for mp3dec is gone as it no longer makes sense
264 for the new buffer tree API.
265 - Fix audible buffer underruns for wma streams.
266 - The alsa writer no longer prints meaningless underrun durations.
267 - audiod: Defaults work also for udp streams. If no filter is
268 given for an audio format that is received via upd, fecdec is
269 automatically added as the first filter (along with the decoder).
270
271 ---------------------------------------
272 0.4.1 (2009-12-22) "concurrent horizon"
273 ---------------------------------------
274
275 Support for another audio format, minor feature enhancements and lots of bug
276 fixes. All fixes that have been accumulated in the maint branch (in particular
277 those mentionened in the 0.3.6 release notes) appear in this release as well.
278
279 - wma support.
280 - new afh option: --human to activate human-readable output.
281 - new server/audiod option: --log-timing to print timing information.
282 - build system improvements.
283 - source code documentation updates.
284
285 -------------------------------------
286 0.3.6 (2009-12-07) "cubic continuity"
287 -------------------------------------
288
289 Quite a few bugs have been found and fixed since 0.3.5, so here's
290 another 0.3.x release. No new features.
291
292 - Always check return value of malloc().
293 - ogg vorbis/FEC: Do not write garbage after the audio file header.
294 - exit if root privileges could not be dropped.
295 - FEC: Fix computation of extra slices.
296 - oss: Fix check for empty input buffer.
297 - Avoid buffer underruns due to filter chain output buffer constraints.
298 - server: Fix assignment of afs_pid.
299 - Don't panic if the afs database contains unknown audio formats.
300 - http/dccp: Do not send the audio file header twice.
301 - FEC: Timing improvements.
302
303 ----------------------------------------------
304 0.4.0 (2009-11-10) "simultaneous independence"
305 ----------------------------------------------
306
307 Two significant changes which require the new version number: The
308 improved authentication dialog and the fact that the database code
309 has been moved to a library, libosl. To use the new version, you have
310 to generate new RSA keys, see INSTALL for details. A shell script is
311 provided for conversion of the 0.3 database to the new 0.4 format.
312
313 - stronger crypto for client authentication
314 - the database code has been moved to a library
315 - improved status item handling
316 - cleanup of the build system
317 - The "-V" option now also prints the git version
318 - the new parser-friendly listing mode for the ls and stat commands
319 - mandatory rc4 encryption
320 - major audio format handler cleanups
321 - (id3,...) tags are no longer stored as a combined string in the database
322 - new mood methods: artist_matches, title_matches, comment_matches,
323 album_matches, year_maches, year.
324
325 --------------------------------------------
326 0.3.5 (2009-09-21) "symplectic separability"
327 --------------------------------------------
328
329 Full client support for *BSD Unixes, complete re-write of the ogg
330 vorbis audio format handler, various improvements all over the place
331 and the usual mix of bugfixes. This release marks the end of the 0.3
332 series if no serious problems show up.
333
334 - the new oss writer (supported on *BSD and Linux)
335 - rewrite of the ogg vorbis audio format handler. It's
336 recommended to replace the chunk tables of existing ogg
337 vorbis files in the afs database by re-adding these files
338 with "add -f".
339 - support for netmask subsets (Gerrit Renker)
340 - the new prebuffer filter
341 - improved signal handling
342 - variable fec output buffer size
343 - improved FEC timing fixes audible buffer underruns in UDP mode
344 - --log_color actually works
345 - new ls option: -d (print dates as seconds after the epoch)
346 - update to gengetopt 2.22.2
347 - support for RSA keys of size > 512 bits
348 - new option "mixer_channel" for para_fade
349
350 -----------------------------------------
351 0.3.4 (2009-05-07) "elliptic inheritance"
352 -----------------------------------------
353
354 The new udp sender, forward error correction, colored logs and various
355 other improvements. As the udp sender does not depend on any special
356 libraries, it is built unconditionally.
357
358 - The udp sender replaces the ortp sender. The new code uses forward
359 error correction to protect against packet losses. Many thanks to
360 Gerrit Renker for providing ipv6 support.
361 - The default port for udp streaming now defaults to 8000, like
362 for the http and the dccp senders/receivers.
363 - Loglevels are now specified as symbolic names, e.g.
364 "--loglevel info".
365 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
366 - para_server/para_audiod: Color support for log messages.
367 - new options for mp3dec: --ignore-crc, --bufsize
368 - new audiod option: --config-file.
369 - gengetopt cleanups.
370 - Improved help/man pages: The documentation of para_audiod,
371 para_recv, para_filter and para_write now also contains
372 all options of the available receivers/filters/writers. The
373 man page of para_fade contains a description of the different
374 modes of operation.
375 - More source code documentation.
376 - vss timing fixes.
377
378 --------------------------------------------
379 0.3.3 (2008-12-01) "axiomatic perspectivity"
380 --------------------------------------------
381
382 Internal code cleanups, bug fixes, improved tag handling and the new
383 amplification filter.
384
385 - para_server uses the generic scheduling code.
386 - overhaul of the virtual streaming system.
387 - mp3: id3 version 2 support via libid3tag (optional)
388 - ogg: vorbis comment support.
389 - aac meta info support.
390 - mp3 audio format handler cleanups.
391 - new filter: "amp" to amplify the amplitude of the audio stream
392 - new status item/database entry: amplification. It is
393 used by the amp filter to pre-amplify the audio stream.
394 - fix a close-without-open bug in para_write.
395 - fix a bug in com_init() which was introduced in 0.3.2.
396 - better error diagnostics for para_client.
397
398 -----------------------------------------
399 0.3.2 (2008-04-11) "probabilistic parity"
400 -----------------------------------------
401
402 The new para_afh executable, scheduling and documentation improvements.
403
404 - new ls option: -lc (list chunk table)
405 - new executable: para_afh, the stand-alone audio file handler tool
406 - afs commands can send output more than SHMMAX (32MB on Linux). This
407 also reduces the memory usage of commands that produce large amounts
408 of output.
409 - major scheduler and audiod cleanups.
410 - more detailed and much nicer man pages.
411
412 ---------------------------------------
413 0.3.1 (2008-02-23) "liquid interaction"
414 ---------------------------------------
415
416 A mix of cleanups, bug fixes, improvements, and some new features. No
417 significant changes to the new database (osl) code, which is generally
418 a good sign.
419
420 - Share some similar/duplicate code between the http and the
421 dccp sender.
422 - Generic access control lists for paraslash senders.
423 - dccp sender: Access control lists, connection limiting and support
424 for the allow,deny,on,off,help sender commands.
425 - The default dccp port changed from 5001 to 8000 (suggested by
426 Gerrit Renker).
427 - para_server starts even if not all public keys could be loaded.
428 - Audiod performance improvements.
429 - fix a bug in the "off" command of the http sender.
430 - fix some fd and memory leaks.
431 - Update to gengetopt-2.22.
432
433 -------------------------------------
434 0.3.0 (2008-01-12) "solar saturation"
435 -------------------------------------
436
437 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
438
439
440 Usually one might expect lots of new features AND a big increase in size
441 for a major release like this.
442
443 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
444 ever. The decrease in size is mostly due to the removal of some
445 graphical tools (which were only quick hacks anyway). But also the
446 fact that the mysql code is gone cuts down the size a bit.
447
448 Being independent of mysql comes at a cost: The fact that paraslash
449 now contains its own database (the object storage layer, osl) increases
450 the (stripped) binary size of para_server by ~50K on i386.
451
452 - no more restrictions on unique basenames.
453 - independent of mysql: The new self-contained object
454 storage layer (osl) replaces the mysql database.
455 - New executable para_fsck: Check integrity of osl tables.
456 - Lyrics support.
457 - Reliable audio file move/rename detection.
458 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
459 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
460 Solaris (sparc64).
461 - the new osl-based audio file selector (afs) replaces the random,
462 the playlist and the mysql selector of paraslash-0.2.x.
463 - IPv6 support (thanks to Gerrit Renker).
464 - paraslash-0.2.x streams are now called "moods". Writing
465 0.3.x-mood definitions should be both easier and more
466 powerful than writing 0.2.x-stream definitions.
467 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
468 been removed. The world is a better place without them. However,
469 para_gui is still there.
470 - afs tracks audio file selection also in playlist mode.
471 - few easy-to-use afs commands replace the many not-so-easy-to-use
472 mysql commands (and are available also in playlist mode).
473 - Improved error subsystem.
474 - The earth-shaking new logo.
475
476 -----------------------------------------
477 0.2.17 (2007-11-20) "isotropic threshold"
478 -----------------------------------------
479
480 Mainly bugfixes and cleanups in this version which marks the end of
481 the 0.2.x series if no serious bugs show up after the release.
482
483 - mysql_selector: fix a locking bug.
484 - universal chunk queueing.
485 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
486 to Gerrit Renker).
487 - be more carful wrt. signed vs. unsigned argument passing.
488 - cleanup error.h and fix some references to invalid error
489 codes.
490 - update to gengetopt-2.21.
491 - update to ortp-0.13.1.
492 - autoconf: extend checks for headers, library functions and
493 compiler characteristics.
494 - Fix streaming of large mp3 files.
495 - Fix an off-by-one bug in playlist handling.
496
497 --------------------------------------
498 0.2.16 (2007-04-05) "neural discharge"
499 --------------------------------------
500
501 The main change in this release is the major audio format handler
502 cleanup which removes some similar/duplicate code and makes it easier
503 to implement plugins for other audio formats. Of course, the usual mix
504 of other improvements/changes/bugfixes also made it into the release.
505
506 - simplified audio format handlers (most of the handling functions
507 were moved one layer up to the virtual streaming system).
508 - para_server uses mmap to read audio files
509 - repositioning of mp3 streams is much faster, in particular for
510 jumping near the end of large mp3 files.
511 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
512 and AFS_WRITE.
513 - fix a bug in para_filter that caused decoding of aac files
514 to start only after a few seconds.
515 - fix osx_writer hangs
516 - simplified dccp code (thanks to Gerrit Renker)
517 - the compress filter works also on big endian systems (ppc)
518
519 -----------------------------------------
520 0.2.15 (2007-02-16) "inductive resonance"
521 -----------------------------------------
522
523 Minor improvements, more documentation and a bunch of bug fixes.
524
525 - para_server: The server.users file is only read once on server
526 startup rather than for each connection
527 - mp3dec: Fix decoding of corrupt mp3 files
528 - afs (audio file sender) is now called vss (virtual streaming
529 system). Consequently, the permission flags specified in
530 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
531 become VSS_READ and VSS_WRITE respectively.
532 - para_audiod/para_filter: Fix a bug that caused the last chunk
533 of audio data not being written under certain circumstances
534 - audiod: compute the difference of server time and local time
535 correctly
536 - para_server/para_audiod: Fix some memory leaks
537 - documentation improvements
538 - configure.ac: fix checks for para_krell
539 - new man pages
540
541 -------------------------------------------
542 0.2.14 (2006-10-15) "transient singularity"
543 -------------------------------------------
544
545 The only major enhancement of this version is the osx writer which completes
546 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
547 until now for reasons beyond the scope of this changelog entry.
548
549 - new output plugin for Mac Os: the osx writer
550 - rename configure command line options from --enable-xxx-headers to
551 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
552 - configure: new command line options: --with-mad-headers,
553 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
554 - some robustness fixes
555 - dymamic audio format recognition for audiod
556 - para_server: new command line option: --autoplay_delay
557 - para_audiod: new command line option: --clock_diff_count
558
559 ---------------------------------------
560 0.2.13 (2006-07-14) "sonic convolution"
561 ---------------------------------------
562
563 A bunch of new features and core changes.
564
565 - the new paraslash scheduler, short and sweet.
566 - Support for m4a/mp4 files via the new aac audio format
567 handler/filter (requires libfaad).
568 - each writer has its own command line parser, just like
569 para_recv and para_filter.
570 - para_client and para_audioc use the error subsystem
571 - writers are integrated in para_audiod (currently linux-only)
572 - para_client is integrated in para_audiod
573 - random/playlist selector: improved info strings
574 - new audiod commands: tasks, kill
575 - update to libortp-0.10.1
576 - para_fade: wake time defaults to 8 hours from now
577 - update to autoconf-2.60
578
579 ------------------------------------------
580 0.2.12 (2006-05-12) "oriented abstraction"
581 ------------------------------------------
582
583 Many user-visible changes in this release and lots of new
584 features:
585
586
587 - the new optional dccp sender/receiver. It uses the datagram
588 congestion control protocol. You'll need a fairly new kernel
589 for this.
590 - paraslash works on Mac OS X (thanks to Gerd Becker)
591 - para_play renamed to para_write
592 - modular output plugin design (writers) for para_write
593 - new file_writer output plugin for para_write
594 - compress filter speed improvements
595 - update to libortp-0.9.1
596 - update to gengetopt-2.17rc
597 - para_client no longer depends on libreadline (as the
598 code for the interactive mode was removed).
599 - gcc-2-95 is no longer a supported compiler. It may still
600 work, but it gets no more testing.
601 - the tarball no longer contains the screenshot images which
602 reduces its size quite a bit.
603 - configure: new command line options: --enable-mysql-headers
604 and --enable-mysql-libs
605
606 ------------------------------------
607 0.2.11 (2006-03-11) "atomic duality"
608 ------------------------------------
609
610 Here it is, the first paraslash release developed with git. There
611 are fairly many user-visible changes in this release. As two out of
612 the three "database tools" of paraslash don't use a database at all,
613 they are now called "audio file selectors" instead.
614
615
616 - the cdt command (change database tool) becomes chs (change
617 selector)
618 - no more colon separators: The syntax of some options of
619 para_audiod and para_filter have changed. Use --help for
620 more info (and some examples).
621 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
622 - switch from cvs to git (should've done that earlier)
623 - the new ipc subsystem
624 - new audio file selector: playlist
625 - para_server: the dopey selector is now called "random",
626 and is the default selector. Use the --selector option to
627 choose another selector at startup, or the chs command to
628 change the selector at runtime.
629 - X86_64 fixes (thanks to Steffen Klassert)
630 - para_play fixes
631
632 --------------------------------------
633 0.2.10 (2006-02-17) "cyclic attractor"
634 --------------------------------------
635
636 Huge documentation update, a scrollable window for para_gui, ortp
637 improvements, and of course many small fixes not mentioned here.
638 The diffstat below is rather misleading as most insertions are due
639 to the new source documentation.
640
641 - autoconf cleanup
642 - para_server also uses the new error subsystem
643 - lots of new documentation (UTSL)
644 - gui improvements:
645 - keysyms for cursor keys and for next/previous page keys
646 - scrollable output window
647 - new internal commands: scroll up/down, page up/down
648 - fix color of command output.
649 - ortp: the --chunk_time and --header flags are no longer needed
650 for para_recv/para_audiod as this information is now encoded in
651 each rtp packet sent by para_server.
652
653 -------------------------------------------
654 0.2.9 (2006-01-24) "progressive turbulence"
655 -------------------------------------------
656
657 Internal audiod receivers/filters, the new error subsystem and
658 a lot of small improvements.
659
660 - para_recv and para_filter are integrated into the para_audiod
661 binary, i.e. audiod no longer spawns a new process for
662 each receiver/filter. As para_recv and para_filter might be
663 useful as standalone programs, they still get built (linked
664 against the same object files that are also used for audiod).
665 - further ortp timing improvements should reduce the CPU usage
666 of the ortp receiver.
667 - improved audio grabbing. The 'grab' command of para_audiod
668 has its own set of command line options. Read the output of
669 "para_audioc help grab" for more info.
670 - oggdec: configurable input prebuffer size.
671 - the new error subsystem gives better error diagnostics
672 and reduces code size.
673
674 -----------------------------------------
675 0.2.8 (2006-01-02) "dynamic accumulation"
676 -----------------------------------------
677
678 The new modular filter design and the para_play-hangs bugfix.
679
680 - new executable: para_filter. It combines para_mp3dec,
681 para_oggdec and para_compress. It also adds a further filter
682 type, wav, that just inserts a wave header at the desired point
683 of the filter chain. All 'piping' is done in-memory (i.e. no
684 read/write operations are used).
685 - para_play: fix a stupid bug that caused it to hang under
686 certain circumstances.
687
688 -------------------------------------------
689 0.2.7 (2006-12-27) "transparent invariance"
690 -------------------------------------------
691
692 Not many user-visible changes but a fair amount of internal improvements.
693
694
695 - The http sender buffers data if it can not be sent
696 out immediately (because the socket is not writable). This
697 should prevent para_server from shutting down the connection
698 too early on a loaded network.
699 - para_play also prebuffers data if it is told to start at a
700 future time by the --start_time option.
701 - The return of para_recv: It combines para_ortp_recv and
702 para_http_recv. Use the --receiver option to switch between
703 the two. para_recv builds without libortp, but contains
704 only the http receiver in this case.
705 - update to ortp 0.8.1. As this ortp release contains incompatible
706 changes, para_recv-0.2.7 won't link against older ortp libs.
707 - improved ortp timings.
708 - use of gcc-extensions that #define away for non-gcc and
709 gcc < 3.0.
710
711 -------------------------------------------
712 0.2.6 (2005-10-29) "recursive compensation"
713 -------------------------------------------
714
715 Transparent session encryption (uses openssl's Alleged RC4 cipher),
716 the internal find command and several other improvements and cleanups.
717
718 - Encrypt the session if encryption is requested by the client
719 (default for para_client 0.2.6). This is backwards
720 compatible, so older clients can still connect to para_server
721 0.2.6. Use the new client option --plain to request an
722 uncrypted session (off by default, must be set to on in
723 order to connect to para_server 0.2.x with 0 <= x <= 5).
724 - para_server uses an internal function to locate audio files
725 rather than calling find(1). The server option
726 --mysql_audio_file_dir replaces --mysql_find_cmd.
727 - documentation update
728 - man pages
729 - header file cleanup
730 - para_client code cleanup
731 - para_gui: faster display of output of display commands
732
733 ------------------------------------------
734 0.2.5 (2005-10-13) "aggressive resolution"
735 ------------------------------------------
736
737 This release adds internal senders, i.e. no more external programs are
738 spawned for sending out the audio data. There are two different senders
739 available: The http sender and the ortp sender (former para_send which
740 is no longer needed).
741
742 The new sender code has a plugin-like design so it can be easily
743 extended should there be be any future need for supporting another
744 network streaming protocol. All senders are completely independent of
745 each other. In particular, the http and the ortp sender can operate
746 in parallel.
747
748 - new server command: sender to control senders at runtime.
749 Read the output of "para_server -h" and "para_client help
750 sender" for more information.
751 - para_recv renamed to para_ortp_recv
752 - new executable: para_http_recv, a simple command line
753 http receiver.
754 - major afs/mp3/ogg code simplifications due to internal
755 senders.
756 - ogg timing improvements
757 - fix several minor memory leaks (found by valgrind)
758 - empty stream definitions work again
759 - com_ne(): ignore errors on remove
760 - audiod: fix segfault on server restart
761
762 ---------------------------------------
763 0.2.4 (2005-09-21) "toxic anticipation"
764 ---------------------------------------
765
766 Several small improvements, fixes and the new grab command.
767
768 - audiod:
769 - new command: "grab" to grab the output of the stream reader
770 or any filters. Read the output of "para_audioc help grab"
771 for more information.
772 - fix memory leak
773 - code cleanup
774 - audioc: new command line option: --bufsize to specify a
775 buffer size different from the default size 8192.
776 - improved error diagnostics for para_play.
777 - new configure option: --enable-ssldir so search for openssl in
778 non-standard places
779 - sdl_gui: Make it look nice again for 1024x768
780 - server: report total size of memory allocated with sbrk by malloc,
781 new command line option: --announce_time
782
783 -----------------------------------------
784 0.2.3 (2005-09-01) "hydrophilic movement"
785 -----------------------------------------
786
787 Two new executables and major feature enhancements.
788
789 - audiod filters: It is now possible to specify arbitrary many
790 (including none) filters for each supported audio
791 format. This can be used e.g. for normalizing volume,
792 transforming or grabbing the audio stream, or for using
793 visualizers. Read the output of "para_audiod -h" for the
794 syntax of the new --filter_cmd option.
795 - new executable: para_play, a tiny alsa player. It
796 can play wave files or raw pcm (16 bit little endian)
797 from stdin.
798 - new executable: para_compress, a dynamic range compressor
799 intended to keep audio output at a consistent volume. Derived
800 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
801 - audiod: New option: --stream_delay. This can be used in
802 a local network to syncronize the audio output of all
803 clients that play the same stream.
804
805 ------------------------------------------
806 0.2.2 (2005-08-19) "tangential excitation"
807 ------------------------------------------
808
809 Mostly internal changes in this release, but also some new commands
810 for the mysql database tool.
811
812 - cleanup exec.c, fix para_exec bug
813 - compile time loglevel (log messages below the given level
814 won't be compiled in, which reduces the size of the
815 resulting binaries)
816 - new log macros that shorten the size of the source code.
817 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
818 to send only zeros. With this workaround, para_audioc works
819 again.
820 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
821 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
822 (new entry), "snp" (set numplayed). Read the manual for more
823 information.
824
825 ---------------------------------------
826 0.2.1 (2005-08-15) "surreal experience"
827 ---------------------------------------
828
829 Here comes paraslash-0.2.1. It contains a couple of new features and,
830 surprise, only minor bug fixes.
831
832 - kill noisy mp3 debug message
833 - cleanup of the build system
834 - para_server and para_client directly use the crypto routines
835 of the openssl library rather than invoking the openssl command
836 line utitlity
837 - server/audiod: new option --user to switch to the given user
838 when invoked as root. Read the output of "para_server -h" for
839 more information.
840 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
841 status. Default: "para_audioc stat"
842 - sdl_gui: new option --pic_cmd to be used to download the picture.
843 Default: "para_client pic"
844 - audiod: 5 slots ought to be enough for everybody
845 - audiod: new status item: Uptime, kill hup command
846
847 ------------------------------------------
848 0.2.0 (2005-08-06) "distributed diffusion"
849 ------------------------------------------
850
851 After several month of increased development activity, paraslash-0.2.0
852 has arrived. It contains many new features and is much more
853 self-contained than the old 0.1.x series. Enjoy!
854
855
856 - para_server: fix hang on song change and crash on sighup.
857 Speed up mysql queries. The DIR_LIKE macro is gone.
858 - new executables: para_audiod, the local audio daemon that
859 starts playback (uses SCM_CREDENTIALS socket magic) and
860 para_audioc, the corresponding client.
861 - new executables: para_mp3dec/para_oggdec, two really teensy
862 decoders. para_mp3dec is based on libmad, para_oggdec requires
863 libvorbisfile.
864 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
865 they are now called para_send and para_recv respectively.
866 - documentation updates
867 - para_gui is themable. For now there is the default theme that
868 looks as before and the simple theme: blue and easy.
869 - gui: audio streaming is now handled by audiod. Time display shows
870 playback time rather than streaming time
871 - slider: update to libzmw-0.2.0
872 - para_krell: fix crash on server shutdown
873 - switch from gzip to bzip2
874
875 ----------------------------------------
876 0.1.7 (2005-04-18) "melting penetration"
877 ----------------------------------------
878
879 The main change in this release is clearly the oggvorbis rewrite,
880 but there are also lots of smaller changes. If you intend to use both
881 the mp3 and the ogg plugin, it is recommended to use software mixing,
882 e.g. the dmix plugin which is provided by ALSA.
883
884 - new executables: para_ovsend and para_ovrecv for sending/receiving
885 oggvorbis files via rtp. Requires the open rtp library. Get it at
886 http://www.linphone.org/ortp/
887 - rewrite of the ogg_vorbis core code
888 - configure detects libzmw and, if detected, includes
889 para_slider to the list of binaries to be built by make
890 - server stream writers read from their associated fifo rather
891 than from stdin
892 - slider: two new sliders, lastplayed and numplayed
893 - fix nasty double free bug which caused random segfaults in case of
894 mp3 files with invalid header information
895 - gui: new command line option: --stream_timeout=seconds to
896 deactivate a slot if it is idle for that many seconds (default=`5')
897 - diffstats
898
899 ---------------------------------------
900 0.1.6 (2005-03-05) "asymptotic balance"
901 ---------------------------------------
902
903 Only little user-visible changes in this release. Mainly bugfixes and
904 core code cleanup. This is probably the most stable version ever if you
905 stick to mp3...
906
907 - fix several memory leaks
908 - rename default name of mysql database from "music" to "paraslash".
909 Use para_server's --mysql_database option if you do not want to
910 rename your old database.
911 - rework ogg vorbis code
912 - make update command work on mysql servers with LOCAL_INFILE
913 disabled
914 - gui: improved stream I/O (slots)
915 - simplified audio format API
916 - para_pob_ogg is gone
917
918 ------------------------------------
919 0.1.5 (2004-12-31) "opaque eternity"
920 ------------------------------------
921
922 Let's slide gently into the new year.
923
924 - new: para_slider (not built automatically, type "make
925 para_slider" to build). A toy for those who always felt that
926 creating stream definitions is difficult. See screenshots,
927 README and FEATURES for more info.
928 - improved signal handling. Fixes server segfault on SIGHUP
929 for linux kernels newer than Aug 24 2004 and makes para_gui
930 race-free.
931 - reload database tool on SIGHUP
932 - improved help message for sl
933 - do not log "broken pipe" messages as errors. They are
934 perfectly ok.
935 - fix wrong error message on permission errors
936
937 -----------------------------------------
938 0.1.4 (2004-12-19) "tunneling transition"
939 -----------------------------------------
940
941 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
942 Hopefully, most of them got wiped out with this release. Some
943 enhancements went also in.
944
945 - improved error diagnostics for all commands
946 - stradd/picadd: overwrite previous contents if entry already
947 exists, rather than returning errors
948 - stradd: use current stream if invoked without args
949 - faster (and hopefully more stable) ogg-vorbis handling
950 - para_krell: reap children to avoid zombie-flooding in case
951 no server is running
952 - si: report also server pid
953 - server: don't busy-loop if dbtool reports only invalid files.
954 - gui: CTRL+C works again, fix stream_read command line option
955 - fix pic_add, hist
956 - fix mysql dbtool startup in case no database exists
957 - many small fixes and cleanups
958
959 ---------------------------------------
960 0.1.3: (2004-12-10) "vanishing inertia"
961 ---------------------------------------
962
963 Starting from this release, the database tools are integrated in the
964 server binary. This decreases server startup time, reduces code size
965 and speeds up database commands. However, the layout of the underlying
966 mysql database changed only slightly and 0.1.3 should be backwards
967 compatible in that respect.
968
969 Visible changes:
970
971 - If mysql is not detected at compile time, or fails to init
972 at runtime, fall back to the dopey database tool which should
973 always work.
974 - para_dbtool and dbtool.conf are gone. All mysql specific
975 options are read from server.conf and are prefixed by 'mysql_'.
976 - new command: cdt (change database tool)
977 - new command line option: dbtool (choose startup database tool)
978 - The name of current stream is now stored in the database,
979 so paraslash remembers its current stream when restarted.
980 - new command: csp (change stream and play)
981 - para_gui also reports current database tool and server uptime
982
983 -------------------------------------------
984 0.1.2: (2004-11-28) "spherical fluctuation"
985 -------------------------------------------
986
987 Point release before the big dbtool changes go in.
988
989 - dbtool: rename ca to cam (copy all meta data). It now also
990 copies numplayed and lastplayed time as well as the picture
991 id.
992 - fix endless-loop-bug caused by mp3 files with invalid header
993
994 -----------------------------------------
995 0.1.1: (2004-11-05) "floating atmosphere"
996 -----------------------------------------
997
998 - gkrellm plugin
999 - new dbtool command: mbox. Browse your sound-file collection
1000 with your favorite mail reader.
1001 - several small fixes
1002
1003 -------------------------------------
1004 0.1.0: (2004-10-22) "rotating cortex"
1005 -------------------------------------
1006
1007 - fix logging bug for loglevel > VERBOSE
1008 - fix skip command
1009 - correct timings for vbr mp3s
1010 - modular audio format support
1011 - ogg-vorbis support (experimental)
1012 - new server option: autoplay
1013
1014 -----------------------------------------
1015 0.0.99: (2004-07-25) "harmonic deviation"
1016 -----------------------------------------
1017
1018 - rename projectname from icc to paraslash (play, archive, rate
1019 and stream large audio sets happily)
1020 - paraslash is no longer restricted to one particular audio
1021 streaming software
1022 - new dbtool commands (stradd, strq, strdel) for easy stream
1023 managment w/o configuration file. That obsoletes stream_defs
1024 file/config option for dbtool.
1025 - picadd accepts jpeg data from stdin
1026 - new server commands: ps (select previous stream), sc (song change)
1027 - new default pictures for sdl_gui
1028 - gui: new key_map option for binding commands and internal
1029 functions to arbitrary keys, nice help screen, rip out
1030 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1031 show silly logo on startup
1032 - new executables: para_fade for fading volume, para_dbadm for
1033 manipulating attributes
1034 - cdb adds _all_ tables to mysql database
1035 - revised and beautified documentation
1036 - sample dbtool rewritten in C
1037 - autoconf
1038
1039 ---------------------------------------------
1040 0.0.98: (2003-12-26) "incremental smoothness"
1041 ---------------------------------------------
1042
1043 - kick icecast in favour of poc. That removes some races and reduces
1044 core code considerably.
1045 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1046 give finer info on afs' status.
1047 - gui can start decoder (see config options). Further new gui
1048 commands: refresh (^L), jmp (F1-F10)
