NEWS update.
[paraslash.git] / NEWS
1 ----------------------------------------------
2 0.4.12 (to be announced) "volatile relativity"
3 ----------------------------------------------
4 The new command line player, the resample filter, ALSA support for
5 para_fade, and the improved build system are the highlights of this
6 release which probably marks the end of the 0.4.x series.
7
8 - The afh receiver and the para_play executable.
9 - The resample filter: A sample rate converter based on
10 libsamplerate.
11 - The "versions" directory has been removed from the master
12 branch. The tarballs of the old releases are now available
13 in the new "releases" branch.
14 - Overhaul of the build system: All generated files are now
15 written to the "build" directory.
16 - The modular mixer API and the alsa mixer.
17 - Minor fixes for the osx writer.
18
19 --------------------------------------
20 0.4.11 (2012-07-20) "mutual diversity"
21 --------------------------------------
22
23 The major feature in this release is the new sideband API for
24 client-server communication. This API will be used exclusively starting
25 with 0.5.0, which breaks backward compatibility but allows to get rid
26 of quite some compatibility code. Other noteworthy changes include
27 decoder latency improvements and a long-standing bug fix for the
28 ALSA writer.
29
30 - Sideband connections: If both para_server and para_client
31 support this feature, data is sent as a multiplexed stream.
32 - The --no_default_filters option of para_filter has been
33 removed.
34 - Several fixes and latency improvements to various decoders.
35 - The ALSA writer now limits the prebuffer time to 500ms.
36 - Documentation improvements.
37 - Overhaul of the command_util.sh script.
38 - Fixes for some minor problems found by the clang analyzer.
39 - Compiles (almost) without warnings on gcc-3.
40 - Robustness improvements of the buffer tree code.
41
42 ------------------------------------------
43 0.4.10 (2012-03-30) "heterogeneous vacuum"
44 ------------------------------------------
45
46 Nothing earth-shaking in this release, but quite a few usability
47 improvements and the usual mix of cleanups and fixes.
48
49 - The --no_default_filters option of para_filter has been
50 deprecated. It still works but has no effect and will be
51 removed in the next version.
52 - para_gui now prints also the stderr output of the executing
53 command in the bottom window.
54 - Cleanup and consolidation of the various wrappers for
55 write(), writev(), send() and friends.
56 - The obscure error messages on mmap() failures have been
57 replaced by meaningful messages. This affects mainly
58 para_afh.
59 - para_audioc: Cleanups and memory leak fixes.
60 - Test 0004-server no longer fails if para_server is not
61 being built.
62 - New configure options: --with-id3tag-{headers,libs}.
63
64 -------------------------------------
65 0.4.9 (2011-12-06) "hybrid causality"
66 -------------------------------------
67
68 Support for another audio format, interactive mode for para_client
69 and para_audiod and many small improvements/fixes all over the place.
70
71 - Support for flac, the free lossless audio codec.
72 - Fix for an endless loop in the mp3 decoder for certain
73 (corrupt) mp3 files.
74 - When executed without specifying a command, para_client
75 and para_audioc start an interactive shell (requires
76 libreadline being installed). The interactive mode offers
77 full tab completion and command line history.
78 - autogen.sh now detects a distcc setup and adjusts the
79 parameter for the -j option of make accordingly.
80 - Shared memory areas are no longer restricted to 64K. We now
81 detect the maximal size of a shared memory area at runtime.
82 - cleanup of the internal uptime API.
83 - para_server prefaults the mmapped audio file to avoid
84 delays on slow media.
85 - A new test for the test-suite that exercises the
86 communication between para_server and para_audiod.
87 - The alsa writer eats up less CPU cycles when configured to
88 use the DMIX plugin.
89 - Simplified and unified receiver code.
90 - Makefile cleanups.
91 - Commands which print a list of matching audio files now
92 emit a meaningful error message if no audio file matched the
93 given pattern(s).
94
95 --------------------------------------
96 0.4.8 (2011-08-19) "nested assignment"
97 --------------------------------------
98
99 Gcrypt support, the overhauled osx writer and regex format specifiers
100 are the highlights of this release.
101
102 - support for libgcrypt as a drop-in replacement for openssl.
103 Run configure --enable-cryptolib=gcrypt to link against
104 libgcrypt. The two crypto implementations are compatible to
105 each other, i.e. a para_client executable linked against
106 gcrypt can connect to para_server linked against libssl
107 and vice versa.
108 - Rewrite of the osx writer (output plugin for Mac OS).
109 - audiod: The format specifier for receivers, filters and
110 writers is now treated as a regular expression. This allows
111 to replace 5 lines in the config file (one for each audio
112 format) by one single line. See the manual for details.
113 - The *.cmdline.[ch] files are no longer contained in the released
114 tarballs. This reduces the size of the tarballs but requires
115 gengetopt to build the tarball.
116 - Compiles cleanly also with llvm/clang.
117 - Corrupt mp3 files are handled more gracefully.
118 - The alsa writer uses poll fds instead of computing timeouts.
119 - Cleanup of the generic writer API.
120 - sched: Optimized zero timeouts.
121 - vss timeout cleanups.
122 - oggdec fixes and improvements.
123
124 --------------------------------------
125 0.4.7 (2011-06-01) "infinite rollback"
126 --------------------------------------
127
128 The new ao writer, support for ssh RSA keys and a couple of other
129 enhancements.
130
131 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
132 platforms through the libao audio library.
133 - Support for RSA keys generated with ssh-keygen.
134 - configure: improved options for ogg/vorbis/speex.
135 - The git version reported by --version always matches HEAD.
136 - The autogen script detects the number of processors and
137 runs a parallel make if possible.
138 - Major cleanup of the crypto API.
139 - Documentation updates.
140
141 ------------------------------------------
142 0.4.6 (2011-03-31) "deterministic entropy"
143 ------------------------------------------
144
145 Lots of ogg/vorbis improvements, the new test suite, enhancements
146 for para_gui and a fair amount of other bug fixes.
147
148 - For DCCP/OGG streams the audio file header is only sent once
149 at the beginning of the stream rather than periodically
150 every five seconds. This reduces network traffic and the
151 FEC group size.
152 - The vorbis comment header is replaced by an empty dummy header
153 before the header is sent over the network. This also results in
154 less network traffic and smaller FEC groups.
155 - The new "test" make target allows to perform some sanity checks prior
156 to installing the package.
157 - ogg timing fixes and performance improvements
158 - Scheduler improvements
159 - Proper exit codes for para_write
160 - para_gui: New option --theme to select a startup theme. Several
161 other improvements and fixes.
162 - aacdec error message cleanups
163 - simplified color error handling
164
165 --------------------------------------------
166 0.4.5 (2010-12-17) "symmetric randomization"
167 --------------------------------------------
168
169 Bug fixes, internal cleanups and variable-sized FEC slices.
170
171 - Contains a fix for an invalid-free-bug in the ogg audio format
172 handler code.
173 - Switching off the DCCP sender works again.
174 - para_audiod handles crashes of para_server more robustly.
175 - Internal scheduler and writer cleanups.
176 - Reduced latency due to variable-sized FEC slices.
177 - Improved documentation and error diagnostics.
178 - The build of para_server is now optional, allowing the build
179 to succeed in case libosl is not installed.
180
181 ------------------------------------------
182 0.4.4 (2010-08-06) "persistent regularity"
183 ------------------------------------------
184
185 Support for yet another audio format, para_write improvements and
186 bug fixes.
187
188 - Support for the speex codec.
189 - Support for sample formats other than 16 bit little endian.
190 - error2.h is now created by a perl script which speeds up configure
191 considerably.
192 - Fix a bug in the aac decoder which could lead to segfaults in
193 para_filter/para_audiod.
194 - Fixes for autoconf-2.66.
195
196 ----------------------------------------
197 0.4.3 (2010-07-05) "imaginary radiation"
198 ----------------------------------------
199
200 Many improvements for the DCCP and the UDP transport, the new user
201 manual and the usual mix of bug fixes and internal improvements.
202
203 - FEC support for the DCCP sender (Gerrit Renker). The new
204 --dccp_max_slice_size, --dccp_data_slices_per_group and
205 --dccp_slices_per_group options can be used to set the FEC
206 parameters for the DCCP transport.
207 - DNS lookups for UDP targets (Gerrit Renker).
208 - The new user manual replaces the README, README.afs, REQUIREMENTS
209 and INSTALL documents.
210 - Fix an end-of-file detection bug in the oggdec filter.
211 - The new nonblock API.
212 - Both options of the oggdec filter have been removed.
213 - New debug mode for the internal scheduler.
214
215 ------------------------------------------
216 0.4.2 (2010-04-23) "associative expansion"
217 ------------------------------------------
218
219 It's been some time since the last release, but finally here is
220 paraslash-0.4.2. The bulk of the changes comes from the new buffer
221 tree API, but there are changes all over the tree. Mainly performance
222 and usability improvements, but also quite some bug fixes.
223
224 - The new buffer tree API.
225 - DCCP: Support for CCID negotiation (Gerrit Renker).
226 - UDP robustness fixes.
227 - The --bufsize option for mp3dec is gone as it no longer makes sense
228 for the new buffer tree API.
229 - Fix audible buffer underruns for wma streams.
230 - The alsa writer no longer prints meaningless underrun durations.
231 - audiod: Defaults work also for udp streams. If no filter is
232 given for an audio format that is received via upd, fecdec is
233 automatically added as the first filter (along with the decoder).
234
235 ---------------------------------------
236 0.4.1 (2009-12-22) "concurrent horizon"
237 ---------------------------------------
238
239 Support for another audio format, minor feature enhancements and lots of bug
240 fixes. All fixes that have been accumulated in the maint branch (in particular
241 those mentionened in the 0.3.6 release notes) appear in this release as well.
242
243 - wma support.
244 - new afh option: --human to activate human-readable output.
245 - new server/audiod option: --log-timing to print timing information.
246 - build system improvements.
247 - source code documentation updates.
248
249 -------------------------------------
250 0.3.6 (2009-12-07) "cubic continuity"
251 -------------------------------------
252
253 Quite a few bugs have been found and fixed since 0.3.5, so here's
254 another 0.3.x release. No new features.
255
256 - Always check return value of malloc().
257 - ogg vorbis/FEC: Do not write garbage after the audio file header.
258 - exit if root privileges could not be dropped.
259 - FEC: Fix computation of extra slices.
260 - oss: Fix check for empty input buffer.
261 - Avoid buffer underruns due to filter chain output buffer constraints.
262 - server: Fix assignment of afs_pid.
263 - Don't panic if the afs database contains unknown audio formats.
264 - http/dccp: Do not send the audio file header twice.
265 - FEC: Timing improvements.
266
267 ----------------------------------------------
268 0.4.0 (2009-11-10) "simultaneous independence"
269 ----------------------------------------------
270
271 Two significant changes which require the new version number: The
272 improved authentication dialog and the fact that the database code
273 has been moved to a library, libosl. To use the new version, you have
274 to generate new RSA keys, see INSTALL for details. A shell script is
275 provided for conversion of the 0.3 database to the new 0.4 format.
276
277 - stronger crypto for client authentication
278 - the database code has been moved to a library
279 - improved status item handling
280 - cleanup of the build system
281 - The "-V" option now also prints the git version
282 - the new parser-friendly listing mode for the ls and stat commands
283 - mandatory rc4 encryption
284 - major audio format handler cleanups
285 - (id3,...) tags are no longer stored as a combined string in the database
286 - new mood methods: artist_matches, title_matches, comment_matches,
287 album_matches, year_maches, year.
288
289 --------------------------------------------
290 0.3.5 (2009-09-21) "symplectic separability"
291 --------------------------------------------
292
293 Full client support for *BSD Unixes, complete re-write of the ogg
294 vorbis audio format handler, various improvements all over the place
295 and the usual mix of bugfixes. This release marks the end of the 0.3
296 series if no serious problems show up.
297
298 - the new oss writer (supported on *BSD and Linux)
299 - rewrite of the ogg vorbis audio format handler. It's
300 recommended to replace the chunk tables of existing ogg
301 vorbis files in the afs database by re-adding these files
302 with "add -f".
303 - support for netmask subsets (Gerrit Renker)
304 - the new prebuffer filter
305 - improved signal handling
306 - variable fec output buffer size
307 - improved FEC timing fixes audible buffer underruns in UDP mode
308 - --log_color actually works
309 - new ls option: -d (print dates as seconds after the epoch)
310 - update to gengetopt 2.22.2
311 - support for RSA keys of size > 512 bits
312 - new option "mixer_channel" for para_fade
313
314 -----------------------------------------
315 0.3.4 (2009-05-07) "elliptic inheritance"
316 -----------------------------------------
317
318 The new udp sender, forward error correction, colored logs and various
319 other improvements. As the udp sender does not depend on any special
320 libraries, it is built unconditionally.
321
322 - The udp sender replaces the ortp sender. The new code uses forward
323 error correction to protect against packet losses. Many thanks to
324 Gerrit Renker for providing ipv6 support.
325 - The default port for udp streaming now defaults to 8000, like
326 for the http and the dccp senders/receivers.
327 - Loglevels are now specified as symbolic names, e.g.
328 "--loglevel info".
329 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
330 - para_server/para_audiod: Color support for log messages.
331 - new options for mp3dec: --ignore-crc, --bufsize
332 - new audiod option: --config-file.
333 - gengetopt cleanups.
334 - Improved help/man pages: The documentation of para_audiod,
335 para_recv, para_filter and para_write now also contains
336 all options of the available receivers/filters/writers. The
337 man page of para_fade contains a description of the different
338 modes of operation.
339 - More source code documentation.
340 - vss timing fixes.
341
342 --------------------------------------------
343 0.3.3 (2008-12-01) "axiomatic perspectivity"
344 --------------------------------------------
345
346 Internal code cleanups, bug fixes, improved tag handling and the new
347 amplification filter.
348
349 - para_server uses the generic scheduling code.
350 - overhaul of the virtual streaming system.
351 - mp3: id3 version 2 support via libid3tag (optional)
352 - ogg: vorbis comment support.
353 - aac meta info support.
354 - mp3 audio format handler cleanups.
355 - new filter: "amp" to amplify the amplitude of the audio stream
356 - new status item/database entry: amplification. It is
357 used by the amp filter to pre-amplify the audio stream.
358 - fix a close-without-open bug in para_write.
359 - fix a bug in com_init() which was introduced in 0.3.2.
360 - better error diagnostics for para_client.
361
362 -----------------------------------------
363 0.3.2 (2008-04-11) "probabilistic parity"
364 -----------------------------------------
365
366 The new para_afh executable, scheduling and documentation improvements.
367
368 - new ls option: -lc (list chunk table)
369 - new executable: para_afh, the stand-alone audio file handler tool
370 - afs commands can send output more than SHMMAX (32MB on Linux). This
371 also reduces the memory usage of commands that produce large amounts
372 of output.
373 - major scheduler and audiod cleanups.
374 - more detailed and much nicer man pages.
375
376 ---------------------------------------
377 0.3.1 (2008-02-23) "liquid interaction"
378 ---------------------------------------
379
380 A mix of cleanups, bug fixes, improvements, and some new features. No
381 significant changes to the new database (osl) code, which is generally
382 a good sign.
383
384 - Share some similar/duplicate code between the http and the
385 dccp sender.
386 - Generic access control lists for paraslash senders.
387 - dccp sender: Access control lists, connection limiting and support
388 for the allow,deny,on,off,help sender commands.
389 - The default dccp port changed from 5001 to 8000 (suggested by
390 Gerrit Renker).
391 - para_server starts even if not all public keys could be loaded.
392 - Audiod performance improvements.
393 - fix a bug in the "off" command of the http sender.
394 - fix some fd and memory leaks.
395 - Update to gengetopt-2.22.
396
397 -------------------------------------
398 0.3.0 (2008-01-12) "solar saturation"
399 -------------------------------------
400
401 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
402
403
404 Usually one might expect lots of new features AND a big increase in size
405 for a major release like this.
406
407 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
408 ever. The decrease in size is mostly due to the removal of some
409 graphical tools (which were only quick hacks anyway). But also the
410 fact that the mysql code is gone cuts down the size a bit.
411
412 Being independent of mysql comes at a cost: The fact that paraslash
413 now contains its own database (the object storage layer, osl) increases
414 the (stripped) binary size of para_server by ~50K on i386.
415
416 - no more restrictions on unique basenames.
417 - independent of mysql: The new self-contained object
418 storage layer (osl) replaces the mysql database.
419 - New executable para_fsck: Check integrity of osl tables.
420 - Lyrics support.
421 - Reliable audio file move/rename detection.
422 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
423 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
424 Solaris (sparc64).
425 - the new osl-based audio file selector (afs) replaces the random,
426 the playlist and the mysql selector of paraslash-0.2.x.
427 - IPv6 support (thanks to Gerrit Renker).
428 - paraslash-0.2.x streams are now called "moods". Writing
429 0.3.x-mood definitions should be both easier and more
430 powerful than writing 0.2.x-stream definitions.
431 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
432 been removed. The world is a better place without them. However,
433 para_gui is still there.
434 - afs tracks audio file selection also in playlist mode.
435 - few easy-to-use afs commands replace the many not-so-easy-to-use
436 mysql commands (and are available also in playlist mode).
437 - Improved error subsystem.
438 - The earth-shaking new logo.
439
440 -----------------------------------------
441 0.2.17 (2007-11-20) "isotropic threshold"
442 -----------------------------------------
443
444 Mainly bugfixes and cleanups in this version which marks the end of
445 the 0.2.x series if no serious bugs show up after the release.
446
447 - mysql_selector: fix a locking bug.
448 - universal chunk queueing.
449 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
450 to Gerrit Renker).
451 - be more carful wrt. signed vs. unsigned argument passing.
452 - cleanup error.h and fix some references to invalid error
453 codes.
454 - update to gengetopt-2.21.
455 - update to ortp-0.13.1.
456 - autoconf: extend checks for headers, library functions and
457 compiler characteristics.
458 - Fix streaming of large mp3 files.
459 - Fix an off-by-one bug in playlist handling.
460
461 --------------------------------------
462 0.2.16 (2007-04-05) "neural discharge"
463 --------------------------------------
464
465 The main change in this release is the major audio format handler
466 cleanup which removes some similar/duplicate code and makes it easier
467 to implement plugins for other audio formats. Of course, the usual mix
468 of other improvements/changes/bugfixes also made it into the release.
469
470 - simplified audio format handlers (most of the handling functions
471 were moved one layer up to the virtual streaming system).
472 - para_server uses mmap to read audio files
473 - repositioning of mp3 streams is much faster, in particular for
474 jumping near the end of large mp3 files.
475 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
476 and AFS_WRITE.
477 - fix a bug in para_filter that caused decoding of aac files
478 to start only after a few seconds.
479 - fix osx_writer hangs
480 - simplified dccp code (thanks to Gerrit Renker)
481 - the compress filter works also on big endian systems (ppc)
482
483 -----------------------------------------
484 0.2.15 (2007-02-16) "inductive resonance"
485 -----------------------------------------
486
487 Minor improvements, more documentation and a bunch of bug fixes.
488
489 - para_server: The server.users file is only read once on server
490 startup rather than for each connection
491 - mp3dec: Fix decoding of corrupt mp3 files
492 - afs (audio file sender) is now called vss (virtual streaming
493 system). Consequently, the permission flags specified in
494 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
495 become VSS_READ and VSS_WRITE respectively.
496 - para_audiod/para_filter: Fix a bug that caused the last chunk
497 of audio data not being written under certain circumstances
498 - audiod: compute the difference of server time and local time
499 correctly
500 - para_server/para_audiod: Fix some memory leaks
501 - documentation improvements
502 - configure.ac: fix checks for para_krell
503 - new man pages
504
505 -------------------------------------------
506 0.2.14 (2006-10-15) "transient singularity"
507 -------------------------------------------
508
509 The only major enhancement of this version is the osx writer which completes
510 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
511 until now for reasons beyond the scope of this changelog entry.
512
513 - new output plugin for Mac Os: the osx writer
514 - rename configure command line options from --enable-xxx-headers to
515 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
516 - configure: new command line options: --with-mad-headers,
517 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
518 - some robustness fixes
519 - dymamic audio format recognition for audiod
520 - para_server: new command line option: --autoplay_delay
521 - para_audiod: new command line option: --clock_diff_count
522
523 ---------------------------------------
524 0.2.13 (2006-07-14) "sonic convolution"
525 ---------------------------------------
526
527 A bunch of new features and core changes.
528
529 - the new paraslash scheduler, short and sweet.
530 - Support for m4a/mp4 files via the new aac audio format
531 handler/filter (requires libfaad).
532 - each writer has its own command line parser, just like
533 para_recv and para_filter.
534 - para_client and para_audioc use the error subsystem
535 - writers are integrated in para_audiod (currently linux-only)
536 - para_client is integrated in para_audiod
537 - random/playlist selector: improved info strings
538 - new audiod commands: tasks, kill
539 - update to libortp-0.10.1
540 - para_fade: wake time defaults to 8 hours from now
541 - update to autoconf-2.60
542
543 ------------------------------------------
544 0.2.12 (2006-05-12) "oriented abstraction"
545 ------------------------------------------
546
547 Many user-visible changes in this release and lots of new
548 features:
549
550
551 - the new optional dccp sender/receiver. It uses the datagram
552 congestion control protocol. You'll need a fairly new kernel
553 for this.
554 - paraslash works on Mac OS X (thanks to Gerd Becker)
555 - para_play renamed to para_write
556 - modular output plugin design (writers) for para_write
557 - new file_writer output plugin for para_write
558 - compress filter speed improvements
559 - update to libortp-0.9.1
560 - update to gengetopt-2.17rc
561 - para_client no longer depends on libreadline (as the
562 code for the interactive mode was removed).
563 - gcc-2-95 is no longer a supported compiler. It may still
564 work, but it gets no more testing.
565 - the tarball no longer contains the screenshot images which
566 reduces its size quite a bit.
567 - configure: new command line options: --enable-mysql-headers
568 and --enable-mysql-libs
569
570 ------------------------------------
571 0.2.11 (2006-03-11) "atomic duality"
572 ------------------------------------
573
574 Here it is, the first paraslash release developed with git. There
575 are fairly many user-visible changes in this release. As two out of
576 the three "database tools" of paraslash don't use a database at all,
577 they are now called "audio file selectors" instead.
578
579
580 - the cdt command (change database tool) becomes chs (change
581 selector)
582 - no more colon separators: The syntax of some options of
583 para_audiod and para_filter have changed. Use --help for
584 more info (and some examples).
585 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
586 - switch from cvs to git (should've done that earlier)
587 - the new ipc subsystem
588 - new audio file selector: playlist
589 - para_server: the dopey selector is now called "random",
590 and is the default selector. Use the --selector option to
591 choose another selector at startup, or the chs command to
592 change the selector at runtime.
593 - X86_64 fixes (thanks to Steffen Klassert)
594 - para_play fixes
595
596 --------------------------------------
597 0.2.10 (2006-02-17) "cyclic attractor"
598 --------------------------------------
599
600 Huge documentation update, a scrollable window for para_gui, ortp
601 improvements, and of course many small fixes not mentioned here.
602 The diffstat below is rather misleading as most insertions are due
603 to the new source documentation.
604
605 - autoconf cleanup
606 - para_server also uses the new error subsystem
607 - lots of new documentation (UTSL)
608 - gui improvements:
609 - keysyms for cursor keys and for next/previous page keys
610 - scrollable output window
611 - new internal commands: scroll up/down, page up/down
612 - fix color of command output.
613 - ortp: the --chunk_time and --header flags are no longer needed
614 for para_recv/para_audiod as this information is now encoded in
615 each rtp packet sent by para_server.
616
617 -------------------------------------------
618 0.2.9 (2006-01-24) "progressive turbulence"
619 -------------------------------------------
620
621 Internal audiod receivers/filters, the new error subsystem and
622 a lot of small improvements.
623
624 - para_recv and para_filter are integrated into the para_audiod
625 binary, i.e. audiod no longer spawns a new process for
626 each receiver/filter. As para_recv and para_filter might be
627 useful as standalone programs, they still get built (linked
628 against the same object files that are also used for audiod).
629 - further ortp timing improvements should reduce the CPU usage
630 of the ortp receiver.
631 - improved audio grabbing. The 'grab' command of para_audiod
632 has its own set of command line options. Read the output of
633 "para_audioc help grab" for more info.
634 - oggdec: configurable input prebuffer size.
635 - the new error subsystem gives better error diagnostics
636 and reduces code size.
637
638 -----------------------------------------
639 0.2.8 (2006-01-02) "dynamic accumulation"
640 -----------------------------------------
641
642 The new modular filter design and the para_play-hangs bugfix.
643
644 - new executable: para_filter. It combines para_mp3dec,
645 para_oggdec and para_compress. It also adds a further filter
646 type, wav, that just inserts a wave header at the desired point
647 of the filter chain. All 'piping' is done in-memory (i.e. no
648 read/write operations are used).
649 - para_play: fix a stupid bug that caused it to hang under
650 certain circumstances.
651
652 -------------------------------------------
653 0.2.7 (2006-12-27) "transparent invariance"
654 -------------------------------------------
655
656 Not many user-visible changes but a fair amount of internal improvements.
657
658
659 - The http sender buffers data if it can not be sent
660 out immediately (because the socket is not writable). This
661 should prevent para_server from shutting down the connection
662 too early on a loaded network.
663 - para_play also prebuffers data if it is told to start at a
664 future time by the --start_time option.
665 - The return of para_recv: It combines para_ortp_recv and
666 para_http_recv. Use the --receiver option to switch between
667 the two. para_recv builds without libortp, but contains
668 only the http receiver in this case.
669 - update to ortp 0.8.1. As this ortp release contains incompatible
670 changes, para_recv-0.2.7 won't link against older ortp libs.
671 - improved ortp timings.
672 - use of gcc-extensions that #define away for non-gcc and
673 gcc < 3.0.
674
675 -------------------------------------------
676 0.2.6 (2005-10-29) "recursive compensation"
677 -------------------------------------------
678
679 Transparent session encryption (uses openssl's Alleged RC4 cipher),
680 the internal find command and several other improvements and cleanups.
681
682 - Encrypt the session if encryption is requested by the client
683 (default for para_client 0.2.6). This is backwards
684 compatible, so older clients can still connect to para_server
685 0.2.6. Use the new client option --plain to request an
686 uncrypted session (off by default, must be set to on in
687 order to connect to para_server 0.2.x with 0 <= x <= 5).
688 - para_server uses an internal function to locate audio files
689 rather than calling find(1). The server option
690 --mysql_audio_file_dir replaces --mysql_find_cmd.
691 - documentation update
692 - man pages
693 - header file cleanup
694 - para_client code cleanup
695 - para_gui: faster display of output of display commands
696
697 ------------------------------------------
698 0.2.5 (2005-10-13) "aggressive resolution"
699 ------------------------------------------
700
701 This release adds internal senders, i.e. no more external programs are
702 spawned for sending out the audio data. There are two different senders
703 available: The http sender and the ortp sender (former para_send which
704 is no longer needed).
705
706 The new sender code has a plugin-like design so it can be easily
707 extended should there be be any future need for supporting another
708 network streaming protocol. All senders are completely independent of
709 each other. In particular, the http and the ortp sender can operate
710 in parallel.
711
712 - new server command: sender to control senders at runtime.
713 Read the output of "para_server -h" and "para_client help
714 sender" for more information.
715 - para_recv renamed to para_ortp_recv
716 - new executable: para_http_recv, a simple command line
717 http receiver.
718 - major afs/mp3/ogg code simplifications due to internal
719 senders.
720 - ogg timing improvements
721 - fix several minor memory leaks (found by valgrind)
722 - empty stream definitions work again
723 - com_ne(): ignore errors on remove
724 - audiod: fix segfault on server restart
725
726 ---------------------------------------
727 0.2.4 (2005-09-21) "toxic anticipation"
728 ---------------------------------------
729
730 Several small improvements, fixes and the new grab command.
731
732 - audiod:
733 - new command: "grab" to grab the output of the stream reader
734 or any filters. Read the output of "para_audioc help grab"
735 for more information.
736 - fix memory leak
737 - code cleanup
738 - audioc: new command line option: --bufsize to specify a
739 buffer size different from the default size 8192.
740 - improved error diagnostics for para_play.
741 - new configure option: --enable-ssldir so search for openssl in
742 non-standard places
743 - sdl_gui: Make it look nice again for 1024x768
744 - server: report total size of memory allocated with sbrk by malloc,
745 new command line option: --announce_time
746
747 -----------------------------------------
748 0.2.3 (2005-09-01) "hydrophilic movement"
749 -----------------------------------------
750
751 Two new executables and major feature enhancements.
752
753 - audiod filters: It is now possible to specify arbitrary many
754 (including none) filters for each supported audio
755 format. This can be used e.g. for normalizing volume,
756 transforming or grabbing the audio stream, or for using
757 visualizers. Read the output of "para_audiod -h" for the
758 syntax of the new --filter_cmd option.
759 - new executable: para_play, a tiny alsa player. It
760 can play wave files or raw pcm (16 bit little endian)
761 from stdin.
762 - new executable: para_compress, a dynamic range compressor
763 intended to keep audio output at a consistent volume. Derived
764 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
765 - audiod: New option: --stream_delay. This can be used in
766 a local network to syncronize the audio output of all
767 clients that play the same stream.
768
769 ------------------------------------------
770 0.2.2 (2005-08-19) "tangential excitation"
771 ------------------------------------------
772
773 Mostly internal changes in this release, but also some new commands
774 for the mysql database tool.
775
776 - cleanup exec.c, fix para_exec bug
777 - compile time loglevel (log messages below the given level
778 won't be compiled in, which reduces the size of the
779 resulting binaries)
780 - new log macros that shorten the size of the source code.
781 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
782 to send only zeros. With this workaround, para_audioc works
783 again.
784 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
785 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
786 (new entry), "snp" (set numplayed). Read the manual for more
787 information.
788
789 ---------------------------------------
790 0.2.1 (2005-08-15) "surreal experience"
791 ---------------------------------------
792
793 Here comes paraslash-0.2.1. It contains a couple of new features and,
794 surprise, only minor bug fixes.
795
796 - kill noisy mp3 debug message
797 - cleanup of the build system
798 - para_server and para_client directly use the crypto routines
799 of the openssl library rather than invoking the openssl command
800 line utitlity
801 - server/audiod: new option --user to switch to the given user
802 when invoked as root. Read the output of "para_server -h" for
803 more information.
804 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
805 status. Default: "para_audioc stat"
806 - sdl_gui: new option --pic_cmd to be used to download the picture.
807 Default: "para_client pic"
808 - audiod: 5 slots ought to be enough for everybody
809 - audiod: new status item: Uptime, kill hup command
810
811 ------------------------------------------
812 0.2.0 (2005-08-06) "distributed diffusion"
813 ------------------------------------------
814
815 After several month of increased development activity, paraslash-0.2.0
816 has arrived. It contains many new features and is much more
817 self-contained than the old 0.1.x series. Enjoy!
818
819
820 - para_server: fix hang on song change and crash on sighup.
821 Speed up mysql queries. The DIR_LIKE macro is gone.
822 - new executables: para_audiod, the local audio daemon that
823 starts playback (uses SCM_CREDENTIALS socket magic) and
824 para_audioc, the corresponding client.
825 - new executables: para_mp3dec/para_oggdec, two really teensy
826 decoders. para_mp3dec is based on libmad, para_oggdec requires
827 libvorbisfile.
828 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
829 they are now called para_send and para_recv respectively.
830 - documentation updates
831 - para_gui is themable. For now there is the default theme that
832 looks as before and the simple theme: blue and easy.
833 - gui: audio streaming is now handled by audiod. Time display shows
834 playback time rather than streaming time
835 - slider: update to libzmw-0.2.0
836 - para_krell: fix crash on server shutdown
837 - switch from gzip to bzip2
838
839 ----------------------------------------
840 0.1.7 (2005-04-18) "melting penetration"
841 ----------------------------------------
842
843 The main change in this release is clearly the oggvorbis rewrite,
844 but there are also lots of smaller changes. If you intend to use both
845 the mp3 and the ogg plugin, it is recommended to use software mixing,
846 e.g. the dmix plugin which is provided by ALSA.
847
848 - new executables: para_ovsend and para_ovrecv for sending/receiving
849 oggvorbis files via rtp. Requires the open rtp library. Get it at
850 http://www.linphone.org/ortp/
851 - rewrite of the ogg_vorbis core code
852 - configure detects libzmw and, if detected, includes
853 para_slider to the list of binaries to be built by make
854 - server stream writers read from their associated fifo rather
855 than from stdin
856 - slider: two new sliders, lastplayed and numplayed
857 - fix nasty double free bug which caused random segfaults in case of
858 mp3 files with invalid header information
859 - gui: new command line option: --stream_timeout=seconds to
860 deactivate a slot if it is idle for that many seconds (default=`5')
861 - diffstats
862
863 ---------------------------------------
864 0.1.6 (2005-03-05) "asymptotic balance"
865 ---------------------------------------
866
867 Only little user-visible changes in this release. Mainly bugfixes and
868 core code cleanup. This is probably the most stable version ever if you
869 stick to mp3...
870
871 - fix several memory leaks
872 - rename default name of mysql database from "music" to "paraslash".
873 Use para_server's --mysql_database option if you do not want to
874 rename your old database.
875 - rework ogg vorbis code
876 - make update command work on mysql servers with LOCAL_INFILE
877 disabled
878 - gui: improved stream I/O (slots)
879 - simplified audio format API
880 - para_pob_ogg is gone
881
882 ------------------------------------
883 0.1.5 (2004-12-31) "opaque eternity"
884 ------------------------------------
885
886 Let's slide gently into the new year.
887
888 - new: para_slider (not built automatically, type "make
889 para_slider" to build). A toy for those who always felt that
890 creating stream definitions is difficult. See screenshots,
891 README and FEATURES for more info.
892 - improved signal handling. Fixes server segfault on SIGHUP
893 for linux kernels newer than Aug 24 2004 and makes para_gui
894 race-free.
895 - reload database tool on SIGHUP
896 - improved help message for sl
897 - do not log "broken pipe" messages as errors. They are
898 perfectly ok.
899 - fix wrong error message on permission errors
900
901 -----------------------------------------
902 0.1.4 (2004-12-19) "tunneling transition"
903 -----------------------------------------
904
905 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
906 Hopefully, most of them got wiped out with this release. Some
907 enhancements went also in.
908
909 - improved error diagnostics for all commands
910 - stradd/picadd: overwrite previous contents if entry already
911 exists, rather than returning errors
912 - stradd: use current stream if invoked without args
913 - faster (and hopefully more stable) ogg-vorbis handling
914 - para_krell: reap children to avoid zombie-flooding in case
915 no server is running
916 - si: report also server pid
917 - server: don't busy-loop if dbtool reports only invalid files.
918 - gui: CTRL+C works again, fix stream_read command line option
919 - fix pic_add, hist
920 - fix mysql dbtool startup in case no database exists
921 - many small fixes and cleanups
922
923 ---------------------------------------
924 0.1.3: (2004-12-10) "vanishing inertia"
925 ---------------------------------------
926
927 Starting from this release, the database tools are integrated in the
928 server binary. This decreases server startup time, reduces code size
929 and speeds up database commands. However, the layout of the underlying
930 mysql database changed only slightly and 0.1.3 should be backwards
931 compatible in that respect.
932
933 Visible changes:
934
935 - If mysql is not detected at compile time, or fails to init
936 at runtime, fall back to the dopey database tool which should
937 always work.
938 - para_dbtool and dbtool.conf are gone. All mysql specific
939 options are read from server.conf and are prefixed by 'mysql_'.
940 - new command: cdt (change database tool)
941 - new command line option: dbtool (choose startup database tool)
942 - The name of current stream is now stored in the database,
943 so paraslash remembers its current stream when restarted.
944 - new command: csp (change stream and play)
945 - para_gui also reports current database tool and server uptime
946
947 -------------------------------------------
948 0.1.2: (2004-11-28) "spherical fluctuation"
949 -------------------------------------------
950
951 Point release before the big dbtool changes go in.
952
953 - dbtool: rename ca to cam (copy all meta data). It now also
954 copies numplayed and lastplayed time as well as the picture
955 id.
956 - fix endless-loop-bug caused by mp3 files with invalid header
957
958 -----------------------------------------
959 0.1.1: (2004-11-05) "floating atmosphere"
960 -----------------------------------------
961
962 - gkrellm plugin
963 - new dbtool command: mbox. Browse your sound-file collection
964 with your favorite mail reader.
965 - several small fixes
966
967 -------------------------------------
968 0.1.0: (2004-10-22) "rotating cortex"
969 -------------------------------------
970
971 - fix logging bug for loglevel > VERBOSE
972 - fix skip command
973 - correct timings for vbr mp3s
974 - modular audio format support
975 - ogg-vorbis support (experimental)
976 - new server option: autoplay
977
978 -----------------------------------------
979 0.0.99: (2004-07-25) "harmonic deviation"
980 -----------------------------------------
981
982 - rename projectname from icc to paraslash (play, archive, rate
983 and stream large audio sets happily)
984 - paraslash is no longer restricted to one particular audio
985 streaming software
986 - new dbtool commands (stradd, strq, strdel) for easy stream
987 managment w/o configuration file. That obsoletes stream_defs
988 file/config option for dbtool.
989 - picadd accepts jpeg data from stdin
990 - new server commands: ps (select previous stream), sc (song change)
991 - new default pictures for sdl_gui
992 - gui: new key_map option for binding commands and internal
993 functions to arbitrary keys, nice help screen, rip out
994 soundcard/linux specific stuff, avoid noise artefacts while jumping,
995 show silly logo on startup
996 - new executables: para_fade for fading volume, para_dbadm for
997 manipulating attributes
998 - cdb adds _all_ tables to mysql database
999 - revised and beautified documentation
1000 - sample dbtool rewritten in C
1001 - autoconf
1002
1003 ---------------------------------------------
1004 0.0.98: (2003-12-26) "incremental smoothness"
1005 ---------------------------------------------
1006
1007 - kick icecast in favour of poc. That removes some races and reduces
1008 core code considerably.
1009 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1010 give finer info on afs' status.
1011 - gui can start decoder (see config options). Further new gui
1012 commands: refresh (^L), jmp (F1-F10)
1013 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1014 terminates gui. This fixes dead instances consuming memory
1015 continuously.
1016 - new dbtool command: verb for sending verbatim sql queries.
1017 - fix pid_list races (by removing pid_list)
1018 - codename funnies
1019
1020 --------------------
1021 0.0.97: (2003-10-26)
1022 --------------------
1023
1024 - installation prefix now defaults to /usr/local
1025 - new commands for gui: snozze, sleep and reread config
1026 - config file for gui and sdl_gui
1027 - fix problems with filenames containing funny characters
1028 (reported by Thomas Forell)
1029 - improved signal handling for gui, now it rereads conf on SIGHUP
1030 - new dbtool command: cdb (create database)
1031 - switch from argtable to gengetopt
1032 - major code cleanup and speed improvements
1033 - fix several potential buffer overflows
1034 - many small fixes and cleanups
1035
1036 -------------------
1037 0.0.96 (2003-08-30)
1038 -------------------
1039
1040 - easy stream_defs syntax
1041 - sdl_gui can display images associated to the file being played
1042 - Major feature enhancements for icc_gui including dynamic text
1043 placement and the top/bottom window design
1044 - vrfy/clean now also checks for NULL values in attributes as
1045 well as for invalid picture pointers
1046 - fix long outstanding case sensitivity bug
1047 - many small fixes and cleanups
1048
1049 -------------------
1050 0.0.95 (2003-06-29)
1051 -------------------
1052
1053 - sdl gui runs much faster
1054 - new dbtool command: ca (copy attributes)
