[paraslash.git] / NEWS
1 -------------------------------------------
2 0.4.8 (to be announced) "nested assignment"
3 -------------------------------------------
4
5 Gcrypt support, the overhauled osx writer and regex format specifiers
6 are the highlights of this release.
7
8 - support for libgcrypt as a drop-in replacement for openssl.
9 Run configure --enable-cryptolib=gcrypt to link against
10 libgcrypt. The two crypto implementations are compatible to
11 each other, i.e. a para_client executable linked against
12 gcrypt can connect to para_server linked against libssl
13 and vice versa.
14 - Rewrite of the osx writer (output plugin for Mac OS).
15 - audiod: The format specifier for receivers, filters and
16 writers is now treated as a regular expression. This allows
17 to replace 5 lines in the config file (one for each audio
18 format) by one single line. See the manual for details.
19 - The *.cmdline.[ch] files are no longer contained in the released
20 tarballs. This reduces the size of the tarballs but requires
21 gengetopt to build the tarball.
22 - Compiles cleanly also with llvm/clang.
23 - Corrupt mp3 files are handled more gracefully.
24 - The alsa writer uses poll fds instead of computing timeouts.
25 - Cleanup of the generic writer API.
26 - sched: Optimized zero timeouts.
27 - vss timeout cleanups.
28
29 --------------------------------------
30 0.4.7 (2011-06-01) "infinite rollback"
31 --------------------------------------
32
33 The new ao writer, support for ssh RSA keys and a couple of other
34 enhancements.
35
36 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
37 platforms through the libao audio library.
38 - Support for RSA keys generated with ssh-keygen.
39 - configure: improved options for ogg/vorbis/speex.
40 - The git version reported by --version always matches HEAD.
41 - The autogen script detects the number of processors and
42 runs a parallel make if possible.
43 - Major cleanup of the crypto API.
44 - Documentation updates.
45
46 ------------------------------------------
47 0.4.6 (2011-03-31) "deterministic entropy"
48 ------------------------------------------
49
50 Lots of ogg/vorbis improvements, the new test suite, enhancements
51 for para_gui and a fair amount of other bug fixes.
52
53 - For DCCP/OGG streams the audio file header is only sent once
54 at the beginning of the stream rather than periodically
55 every five seconds. This reduces network traffic and the
56 FEC group size.
57 - The vorbis comment header is replaced by an empty dummy header
58 before the header is sent over the network. This also results in
59 less network traffic and smaller FEC groups.
60 - The new "test" make target allows to perform some sanity checks prior
61 to installing the package.
62 - ogg timing fixes and performance improvements
63 - Scheduler improvements
64 - Proper exit codes for para_write
65 - para_gui: New option --theme to select a startup theme. Several
66 other improvements and fixes.
67 - aacdec error message cleanups
68 - simplified color error handling
69
70 --------------------------------------------
71 0.4.5 (2010-12-17) "symmetric randomization"
72 --------------------------------------------
73
74 Bug fixes, internal cleanups and variable-sized FEC slices.
75
76 - Contains a fix for an invalid-free-bug in the ogg audio format
77 handler code.
78 - Switching off the DCCP sender works again.
79 - para_audiod handles crashes of para_server more robustly.
80 - Internal scheduler and writer cleanups.
81 - Reduced latency due to variable-sized FEC slices.
82 - Improved documentation and error diagnostics.
83 - The build of para_server is now optional, allowing the build
84 to succeed in case libosl is not installed.
85
86 ------------------------------------------
87 0.4.4 (2010-08-06) "persistent regularity"
88 ------------------------------------------
89
90 Support for yet another audio format, para_write improvements and
91 bug fixes.
92
93 - Support for the speex codec.
94 - Support for sample formats other than 16 bit little endian.
95 - error2.h is now created by a perl script which speeds up configure
96 considerably.
97 - Fix a bug in the aac decoder which could lead to segfaults in
98 para_filter/para_audiod.
99 - Fixes for autoconf-2.66.
100
101 ----------------------------------------
102 0.4.3 (2010-07-05) "imaginary radiation"
103 ----------------------------------------
104
105 Many improvements for the DCCP and the UDP transport, the new user
106 manual and the usual mix of bug fixes and internal improvements.
107
108 - FEC support for the DCCP sender (Gerrit Renker). The new
109 --dccp_max_slice_size, --dccp_data_slices_per_group and
110 --dccp_slices_per_group options can be used to set the FEC
111 parameters for the DCCP transport.
112 - DNS lookups for UDP targets (Gerrit Renker).
113 - The new user manual replaces the README, README.afs, REQUIREMENTS
114 and INSTALL documents.
115 - Fix an end-of-file detection bug in the oggdec filter.
116 - The new nonblock API.
117 - Both options of the oggdec filter have been removed.
118 - New debug mode for the internal scheduler.
119
120 ------------------------------------------
121 0.4.2 (2010-04-23) "associative expansion"
122 ------------------------------------------
123
124 It's been some time since the last release, but finally here is
125 paraslash-0.4.2. The bulk of the changes comes from the new buffer
126 tree API, but there are changes all over the tree. Mainly performance
127 and usability improvements, but also quite some bug fixes.
128
129 - The new buffer tree API.
130 - DCCP: Support for CCID negotiation (Gerrit Renker).
131 - UDP robustness fixes.
132 - The --bufsize option for mp3dec is gone as it no longer makes sense
133 for the new buffer tree API.
134 - Fix audible buffer underruns for wma streams.
135 - The alsa writer no longer prints meaningless underrun durations.
136 - audiod: Defaults work also for udp streams. If no filter is
137 given for an audio format that is received via upd, fecdec is
138 automatically added as the first filter (along with the decoder).
139
140 ---------------------------------------
141 0.4.1 (2009-12-22) "concurrent horizon"
142 ---------------------------------------
143
144 Support for another audio format, minor feature enhancements and lots of bug
145 fixes. All fixes that have been accumulated in the maint branch (in particular
146 those mentionened in the 0.3.6 release notes) appear in this release as well.
147
148 - wma support.
149 - new afh option: --human to activate human-readable output.
150 - new server/audiod option: --log-timing to print timing information.
151 - build system improvements.
152 - source code documentation updates.
153
154 -------------------------------------
155 0.3.6 (2009-12-07) "cubic continuity"
156 -------------------------------------
157
158 Quite a few bugs have been found and fixed since 0.3.5, so here's
159 another 0.3.x release. No new features.
160
161 - Always check return value of malloc().
162 - ogg vorbis/FEC: Do not write garbage after the audio file header.
163 - exit if root privileges could not be dropped.
164 - FEC: Fix computation of extra slices.
165 - oss: Fix check for empty input buffer.
166 - Avoid buffer underruns due to filter chain output buffer constraints.
167 - server: Fix assignment of afs_pid.
168 - Don't panic if the afs database contains unknown audio formats.
169 - http/dccp: Do not send the audio file header twice.
170 - FEC: Timing improvements.
171
172 ----------------------------------------------
173 0.4.0 (2009-11-10) "simultaneous independence"
174 ----------------------------------------------
175
176 Two significant changes which require the new version number: The
177 improved authentication dialog and the fact that the database code
178 has been moved to a library, libosl. To use the new version, you have
179 to generate new RSA keys, see INSTALL for details. A shell script is
180 provided for conversion of the 0.3 database to the new 0.4 format.
181
182 - stronger crypto for client authentication
183 - the database code has been moved to a library
184 - improved status item handling
185 - cleanup of the build system
186 - The "-V" option now also prints the git version
187 - the new parser-friendly listing mode for the ls and stat commands
188 - mandatory rc4 encryption
189 - major audio format handler cleanups
190 - (id3,...) tags are no longer stored as a combined string in the database
191 - new mood methods: artist_matches, title_matches, comment_matches,
192 album_matches, year_maches, year.
193
194 --------------------------------------------
195 0.3.5 (2009-09-21) "symplectic separability"
196 --------------------------------------------
197
198 Full client support for *BSD Unixes, complete re-write of the ogg
199 vorbis audio format handler, various improvements all over the place
200 and the usual mix of bugfixes. This release marks the end of the 0.3
201 series if no serious problems show up.
202
203 - the new oss writer (supported on *BSD and Linux)
204 - rewrite of the ogg vorbis audio format handler. It's
205 recommended to replace the chunk tables of existing ogg
206 vorbis files in the afs database by re-adding these files
207 with "add -f".
208 - support for netmask subsets (Gerrit Renker)
209 - the new prebuffer filter
210 - improved signal handling
211 - variable fec output buffer size
212 - improved FEC timing fixes audible buffer underruns in UDP mode
213 - --log_color actually works
214 - new ls option: -d (print dates as seconds after the epoch)
215 - update to gengetopt 2.22.2
216 - support for RSA keys of size > 512 bits
217 - new option "mixer_channel" for para_fade
218
219 -----------------------------------------
220 0.3.4 (2009-05-07) "elliptic inheritance"
221 -----------------------------------------
222
223 The new udp sender, forward error correction, colored logs and various
224 other improvements. As the udp sender does not depend on any special
225 libraries, it is built unconditionally.
226
227 - The udp sender replaces the ortp sender. The new code uses forward
228 error correction to protect against packet losses. Many thanks to
229 Gerrit Renker for providing ipv6 support.
230 - The default port for udp streaming now defaults to 8000, like
231 for the http and the dccp senders/receivers.
232 - Loglevels are now specified as symbolic names, e.g.
233 "--loglevel info".
234 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
235 - para_server/para_audiod: Color support for log messages.
236 - new options for mp3dec: --ignore-crc, --bufsize
237 - new audiod option: --config-file.
238 - gengetopt cleanups.
239 - Improved help/man pages: The documentation of para_audiod,
240 para_recv, para_filter and para_write now also contains
241 all options of the available receivers/filters/writers. The
242 man page of para_fade contains a description of the different
243 modes of operation.
244 - More source code documentation.
245 - vss timing fixes.
246
247 --------------------------------------------
248 0.3.3 (2008-12-01) "axiomatic perspectivity"
249 --------------------------------------------
250
251 Internal code cleanups, bug fixes, improved tag handling and the new
252 amplification filter.
253
254 - para_server uses the generic scheduling code.
255 - overhaul of the virtual streaming system.
256 - mp3: id3 version 2 support via libid3tag (optional)
257 - ogg: vorbis comment support.
258 - aac meta info support.
259 - mp3 audio format handler cleanups.
260 - new filter: "amp" to amplify the amplitude of the audio stream
261 - new status item/database entry: amplification. It is
262 used by the amp filter to pre-amplify the audio stream.
263 - fix a close-without-open bug in para_write.
264 - fix a bug in com_init() which was introduced in 0.3.2.
265 - better error diagnostics for para_client.
266
267 -----------------------------------------
268 0.3.2 (2008-04-11) "probabilistic parity"
269 -----------------------------------------
270
271 The new para_afh executable, scheduling and documentation improvements.
272
273 - new ls option: -lc (list chunk table)
274 - new executable: para_afh, the stand-alone audio file handler tool
275 - afs commands can send output more than SHMMAX (32MB on Linux). This
276 also reduces the memory usage of commands that produce large amounts
277 of output.
278 - major scheduler and audiod cleanups.
279 - more detailed and much nicer man pages.
280
281 ---------------------------------------
282 0.3.1 (2008-02-23) "liquid interaction"
283 ---------------------------------------
284
285 A mix of cleanups, bug fixes, improvements, and some new features. No
286 significant changes to the new database (osl) code, which is generally
287 a good sign.
288
289 - Share some similar/duplicate code between the http and the
290 dccp sender.
291 - Generic access control lists for paraslash senders.
292 - dccp sender: Access control lists, connection limiting and support
293 for the allow,deny,on,off,help sender commands.
294 - The default dccp port changed from 5001 to 8000 (suggested by
295 Gerrit Renker).
296 - para_server starts even if not all public keys could be loaded.
297 - Audiod performance improvements.
298 - fix a bug in the "off" command of the http sender.
299 - fix some fd and memory leaks.
300 - Update to gengetopt-2.22.
301
302 -------------------------------------
303 0.3.0 (2008-01-12) "solar saturation"
304 -------------------------------------
305
306 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
307
308
309 Usually one might expect lots of new features AND a big increase in size
310 for a major release like this.
311
312 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
313 ever. The decrease in size is mostly due to the removal of some
314 graphical tools (which were only quick hacks anyway). But also the
315 fact that the mysql code is gone cuts down the size a bit.
316
317 Being independent of mysql comes at a cost: The fact that paraslash
318 now contains its own database (the object storage layer, osl) increases
319 the (stripped) binary size of para_server by ~50K on i386.
320
321 - no more restrictions on unique basenames.
322 - independent of mysql: The new self-contained object
323 storage layer (osl) replaces the mysql database.
324 - New executable para_fsck: Check integrity of osl tables.
325 - Lyrics support.
326 - Reliable audio file move/rename detection.
327 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
328 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
329 Solaris (sparc64).
330 - the new osl-based audio file selector (afs) replaces the random,
331 the playlist and the mysql selector of paraslash-0.2.x.
332 - IPv6 support (thanks to Gerrit Renker).
333 - paraslash-0.2.x streams are now called "moods". Writing
334 0.3.x-mood definitions should be both easier and more
335 powerful than writing 0.2.x-stream definitions.
336 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
337 been removed. The world is a better place without them. However,
338 para_gui is still there.
339 - afs tracks audio file selection also in playlist mode.
340 - few easy-to-use afs commands replace the many not-so-easy-to-use
341 mysql commands (and are available also in playlist mode).
342 - Improved error subsystem.
343 - The earth-shaking new logo.
344
345 -----------------------------------------
346 0.2.17 (2007-11-20) "isotropic threshold"
347 -----------------------------------------
348
349 Mainly bugfixes and cleanups in this version which marks the end of
350 the 0.2.x series if no serious bugs show up after the release.
351
352 - mysql_selector: fix a locking bug.
353 - universal chunk queueing.
354 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
355 to Gerrit Renker).
356 - be more carful wrt. signed vs. unsigned argument passing.
357 - cleanup error.h and fix some references to invalid error
358 codes.
359 - update to gengetopt-2.21.
360 - update to ortp-0.13.1.
361 - autoconf: extend checks for headers, library functions and
362 compiler characteristics.
363 - Fix streaming of large mp3 files.
364 - Fix an off-by-one bug in playlist handling.
365
366 --------------------------------------
367 0.2.16 (2007-04-05) "neural discharge"
368 --------------------------------------
369
370 The main change in this release is the major audio format handler
371 cleanup which removes some similar/duplicate code and makes it easier
372 to implement plugins for other audio formats. Of course, the usual mix
373 of other improvements/changes/bugfixes also made it into the release.
374
375 - simplified audio format handlers (most of the handling functions
376 were moved one layer up to the virtual streaming system).
377 - para_server uses mmap to read audio files
378 - repositioning of mp3 streams is much faster, in particular for
379 jumping near the end of large mp3 files.
380 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
381 and AFS_WRITE.
382 - fix a bug in para_filter that caused decoding of aac files
383 to start only after a few seconds.
384 - fix osx_writer hangs
385 - simplified dccp code (thanks to Gerrit Renker)
386 - the compress filter works also on big endian systems (ppc)
387
388 -----------------------------------------
389 0.2.15 (2007-02-16) "inductive resonance"
390 -----------------------------------------
391
392 Minor improvements, more documentation and a bunch of bug fixes.
393
394 - para_server: The server.users file is only read once on server
395 startup rather than for each connection
396 - mp3dec: Fix decoding of corrupt mp3 files
397 - afs (audio file sender) is now called vss (virtual streaming
398 system). Consequently, the permission flags specified in
399 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
400 become VSS_READ and VSS_WRITE respectively.
401 - para_audiod/para_filter: Fix a bug that caused the last chunk
402 of audio data not being written under certain circumstances
403 - audiod: compute the difference of server time and local time
404 correctly
405 - para_server/para_audiod: Fix some memory leaks
406 - documentation improvements
407 - configure.ac: fix checks for para_krell
408 - new man pages
409
410 -------------------------------------------
411 0.2.14 (2006-10-15) "transient singularity"
412 -------------------------------------------
413
414 The only major enhancement of this version is the osx writer which completes
415 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
416 until now for reasons beyond the scope of this changelog entry.
417
418 - new output plugin for Mac Os: the osx writer
419 - rename configure command line options from --enable-xxx-headers to
420 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
421 - configure: new command line options: --with-mad-headers,
422 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
423 - some robustness fixes
424 - dymamic audio format recognition for audiod
425 - para_server: new command line option: --autoplay_delay
426 - para_audiod: new command line option: --clock_diff_count
427
428 ---------------------------------------
429 0.2.13 (2006-07-14) "sonic convolution"
430 ---------------------------------------
431
432 A bunch of new features and core changes.
433
434 - the new paraslash scheduler, short and sweet.
435 - Support for m4a/mp4 files via the new aac audio format
436 handler/filter (requires libfaad).
437 - each writer has its own command line parser, just like
438 para_recv and para_filter.
439 - para_client and para_audioc use the error subsystem
440 - writers are integrated in para_audiod (currently linux-only)
441 - para_client is integrated in para_audiod
442 - random/playlist selector: improved info strings
443 - new audiod commands: tasks, kill
444 - update to libortp-0.10.1
445 - para_fade: wake time defaults to 8 hours from now
446 - update to autoconf-2.60
447
448
449 ------------------------------------------
450 0.2.12 (2006-05-12) "oriented abstraction"
451 ------------------------------------------
452
453 Many user-visible changes in this release and lots of new
454 features:
455
456
457 - the new optional dccp sender/receiver. It uses the datagram
458 congestion control protocol. You'll need a fairly new kernel
459 for this.
460 - paraslash works on Mac OS X (thanks to Gerd Becker)
461 - para_play renamed to para_write
462 - modular output plugin design (writers) for para_write
463 - new file_writer output plugin for para_write
464 - compress filter speed improvements
465 - update to libortp-0.9.1
466 - update to gengetopt-2.17rc
467 - para_client no longer depends on libreadline (as the
468 code for the interactive mode was removed).
469 - gcc-2-95 is no longer a supported compiler. It may still
470 work, but it gets no more testing.
471 - the tarball no longer contains the screenshot images which
472 reduces its size quite a bit.
473 - configure: new command line options: --enable-mysql-headers
474 and --enable-mysql-libs
475
476 ------------------------------------
477 0.2.11 (2006-03-11) "atomic duality"
478 ------------------------------------
479
480 Here it is, the first paraslash release developed with git. There
481 are fairly many user-visible changes in this release. As two out of
482 the three "database tools" of paraslash don't use a database at all,
483 they are now called "audio file selectors" instead.
484
485
486 - the cdt command (change database tool) becomes chs (change
487 selector)
488 - no more colon separators: The syntax of some options of
489 para_audiod and para_filter have changed. Use --help for
490 more info (and some examples).
491 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
492 - switch from cvs to git (should've done that earlier)
493 - the new ipc subsystem
494 - new audio file selector: playlist
495 - para_server: the dopey selector is now called "random",
496 and is the default selector. Use the --selector option to
497 choose another selector at startup, or the chs command to
498 change the selector at runtime.
499 - X86_64 fixes (thanks to Steffen Klassert)
500 - para_play fixes
501
502
503 --------------------------------------
504 0.2.10 (2006-02-17) "cyclic attractor"
505 --------------------------------------
506
507 Huge documentation update, a scrollable window for para_gui, ortp
508 improvements, and of course many small fixes not mentioned here.
509 The diffstat below is rather misleading as most insertions are due
510 to the new source documentation.
511
512 - autoconf cleanup
513 - para_server also uses the new error subsystem
514 - lots of new documentation (UTSL)
515 - gui improvements:
516 - keysyms for cursor keys and for next/previous page keys
517 - scrollable output window
518 - new internal commands: scroll up/down, page up/down
519 - fix color of command output.
520 - ortp: the --chunk_time and --header flags are no longer needed
521 for para_recv/para_audiod as this information is now encoded in
522 each rtp packet sent by para_server.
523
524
525 -------------------------------------------
526 0.2.9 (2006-01-24) "progressive turbulence"
527 -------------------------------------------
528
529 Internal audiod receivers/filters, the new error subsystem and
530 a lot of small improvements.
531
532 - para_recv and para_filter are integrated into the para_audiod
533 binary, i.e. audiod no longer spawns a new process for
534 each receiver/filter. As para_recv and para_filter might be
535 useful as standalone programs, they still get built (linked
536 against the same object files that are also used for audiod).
537 - further ortp timing improvements should reduce the CPU usage
538 of the ortp receiver.
539 - improved audio grabbing. The 'grab' command of para_audiod
540 has its own set of command line options. Read the output of
541 "para_audioc help grab" for more info.
542 - oggdec: configurable input prebuffer size.
543 - the new error subsystem gives better error diagnostics
544 and reduces code size.
545
546
547 -----------------------------------------
548 0.2.8 (2006-01-02) "dynamic accumulation"
549 -----------------------------------------
550
551 The new modular filter design and the para_play-hangs bugfix.
552
553 - new executable: para_filter. It combines para_mp3dec,
554 para_oggdec and para_compress. It also adds a further filter
555 type, wav, that just inserts a wave header at the desired point
556 of the filter chain. All 'piping' is done in-memory (i.e. no
557 read/write operations are used).
558 - para_play: fix a stupid bug that caused it to hang under
559 certain circumstances.
560
561
562 -------------------------------------------
563 0.2.7 (2006-12-27) "transparent invariance"
564 -------------------------------------------
565
566 Not many user-visible changes but a fair amount of internal improvements.
567
568
569 - The http sender buffers data if it can not be sent
570 out immediately (because the socket is not writable). This
571 should prevent para_server from shutting down the connection
572 too early on a loaded network.
573 - para_play also prebuffers data if it is told to start at a
574 future time by the --start_time option.
575 - The return of para_recv: It combines para_ortp_recv and
576 para_http_recv. Use the --receiver option to switch between
577 the two. para_recv builds without libortp, but contains
578 only the http receiver in this case.
579 - update to ortp 0.8.1. As this ortp release contains incompatible
580 changes, para_recv-0.2.7 won't link against older ortp libs.
581 - improved ortp timings.
582 - use of gcc-extensions that #define away for non-gcc and
583 gcc < 3.0.
584
585
586 -------------------------------------------
587 0.2.6 (2005-10-29) "recursive compensation"
588 -------------------------------------------
589
590 Transparent session encryption (uses openssl's Alleged RC4 cipher),
591 the internal find command and several other improvements and cleanups.
592
593 - Encrypt the session if encryption is requested by the client
594 (default for para_client 0.2.6). This is backwards
595 compatible, so older clients can still connect to para_server
596 0.2.6. Use the new client option --plain to request an
597 uncrypted session (off by default, must be set to on in
598 order to connect to para_server 0.2.x with 0 <= x <= 5).
599 - para_server uses an internal function to locate audio files
600 rather than calling find(1). The server option
601 --mysql_audio_file_dir replaces --mysql_find_cmd.
602 - documentation update
603 - man pages
604 - header file cleanup
605 - para_client code cleanup
606 - para_gui: faster display of output of display commands
607
608
609 ------------------------------------------
610 0.2.5 (2005-10-13) "aggressive resolution"
611 ------------------------------------------
612
613 This release adds internal senders, i.e. no more external programs are
614 spawned for sending out the audio data. There are two different senders
615 available: The http sender and the ortp sender (former para_send which
616 is no longer needed).
617
618 The new sender code has a plugin-like design so it can be easily
619 extended should there be be any future need for supporting another
620 network streaming protocol. All senders are completely independent of
621 each other. In particular, the http and the ortp sender can operate
622 in parallel.
623
624 - new server command: sender to control senders at runtime.
625 Read the output of "para_server -h" and "para_client help
626 sender" for more information.
627 - para_recv renamed to para_ortp_recv
628 - new executable: para_http_recv, a simple command line
629 http receiver.
630 - major afs/mp3/ogg code simplifications due to internal
631 senders.
632 - ogg timing improvements
633 - fix several minor memory leaks (found by valgrind)
634 - empty stream definitions work again
635 - com_ne(): ignore errors on remove
636 - audiod: fix segfault on server restart
637
638
639 ---------------------------------------
640 0.2.4 (2005-09-21) "toxic anticipation"
641 ---------------------------------------
642
643 Several small improvements, fixes and the new grab command.
644
645 - audiod:
646 - new command: "grab" to grab the output of the stream reader
647 or any filters. Read the output of "para_audioc help grab"
648 for more information.
649 - fix memory leak
650 - code cleanup
651 - audioc: new command line option: --bufsize to specify a
652 buffer size different from the default size 8192.
653 - improved error diagnostics for para_play.
654 - new configure option: --enable-ssldir so search for openssl in
655 non-standard places
656 - sdl_gui: Make it look nice again for 1024x768
657 - server: report total size of memory allocated with sbrk by malloc,
658 new command line option: --announce_time
659
660
661 -----------------------------------------
662 0.2.3 (2005-09-01) "hydrophilic movement"
663 -----------------------------------------
664
665 Two new executables and major feature enhancements.
666
667 - audiod filters: It is now possible to specify arbitrary many
668 (including none) filters for each supported audio
669 format. This can be used e.g. for normalizing volume,
670 transforming or grabbing the audio stream, or for using
671 visualizers. Read the output of "para_audiod -h" for the
672 syntax of the new --filter_cmd option.
673 - new executable: para_play, a tiny alsa player. It
674 can play wave files or raw pcm (16 bit little endian)
675 from stdin.
676 - new executable: para_compress, a dynamic range compressor
677 intended to keep audio output at a consistent volume. Derived
678 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
679 - audiod: New option: --stream_delay. This can be used in
680 a local network to syncronize the audio output of all
681 clients that play the same stream.
682
683
684 ------------------------------------------
685 0.2.2 (2005-08-19) "tangential excitation"
686 ------------------------------------------
687
688 Mostly internal changes in this release, but also some new commands
689 for the mysql database tool.
690
691 - cleanup exec.c, fix para_exec bug
692 - compile time loglevel (log messages below the given level
693 won't be compiled in, which reduces the size of the
694 resulting binaries)
695 - new log macros that shorten the size of the source code.
696 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
697 to send only zeros. With this workaround, para_audioc works
698 again.
699 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
700 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
701 (new entry), "snp" (set numplayed). Read the manual for more
702 information.
703
704
705 ---------------------------------------
706 0.2.1 (2005-08-15) "surreal experience"
707 ---------------------------------------
708
709 Here comes paraslash-0.2.1. It contains a couple of new features and,
710 surprise, only minor bug fixes.
711
712 - kill noisy mp3 debug message
713 - cleanup of the build system
714 - para_server and para_client directly use the crypto routines
715 of the openssl library rather than invoking the openssl command
716 line utitlity
717 - server/audiod: new option --user to switch to the given user
718 when invoked as root. Read the output of "para_server -h" for
719 more information.
720 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
721 status. Default: "para_audioc stat"
722 - sdl_gui: new option --pic_cmd to be used to download the picture.
723 Default: "para_client pic"
724 - audiod: 5 slots ought to be enough for everybody
725 - audiod: new status item: Uptime, kill hup command
726
727
728
729 ------------------------------------------
730 0.2.0 (2005-08-06) "distributed diffusion"
731 ------------------------------------------
732
733 After several month of increased development activity, paraslash-0.2.0
734 has arrived. It contains many new features and is much more
735 self-contained than the old 0.1.x series. Enjoy!
736
737
738 - para_server: fix hang on song change and crash on sighup.
739 Speed up mysql queries. The DIR_LIKE macro is gone.
740 - new executables: para_audiod, the local audio daemon that
741 starts playback (uses SCM_CREDENTIALS socket magic) and
742 para_audioc, the corresponding client.
743 - new executables: para_mp3dec/para_oggdec, two really teensy
744 decoders. para_mp3dec is based on libmad, para_oggdec requires
745 libvorbisfile.
746 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
747 they are now called para_send and para_recv respectively.
748 - documentation updates
749 - para_gui is themable. For now there is the default theme that
750 looks as before and the simple theme: blue and easy.
751 - gui: audio streaming is now handled by audiod. Time display shows
752 playback time rather than streaming time
753 - slider: update to libzmw-0.2.0
754 - para_krell: fix crash on server shutdown
755 - switch from gzip to bzip2
756
757
758 ----------------------------------------
759 0.1.7 (2005-04-18) "melting penetration"
760 ----------------------------------------
761
762 The main change in this release is clearly the oggvorbis rewrite,
763 but there are also lots of smaller changes. If you intend to use both
764 the mp3 and the ogg plugin, it is recommended to use software mixing,
765 e.g. the dmix plugin which is provided by ALSA.
766
767 - new executables: para_ovsend and para_ovrecv for sending/receiving
768 oggvorbis files via rtp. Requires the open rtp library. Get it at
769 http://www.linphone.org/ortp/
770 - rewrite of the ogg_vorbis core code
771 - configure detects libzmw and, if detected, includes
772 para_slider to the list of binaries to be built by make
773 - server stream writers read from their associated fifo rather
774 than from stdin
775 - slider: two new sliders, lastplayed and numplayed
776 - fix nasty double free bug which caused random segfaults in case of
777 mp3 files with invalid header information
778 - gui: new command line option: --stream_timeout=seconds to
779 deactivate a slot if it is idle for that many seconds (default=`5')
780 - diffstats
781
782
783 ---------------------------------------
784 0.1.6 (2005-03-05) "asymptotic balance"
785 ---------------------------------------
786
787 Only little user-visible changes in this release. Mainly bugfixes and
788 core code cleanup. This is probably the most stable version ever if you
789 stick to mp3...
790
791 - fix several memory leaks
792 - rename default name of mysql database from "music" to "paraslash".
793 Use para_server's --mysql_database option if you do not want to
794 rename your old database.
795 - rework ogg vorbis code
796 - make update command work on mysql servers with LOCAL_INFILE
797 disabled
798 - gui: improved stream I/O (slots)
799 - simplified audio format API
800 - para_pob_ogg is gone
801
802 ------------------------------------
803 0.1.5 (2004-12-31) "opaque eternity"
804 ------------------------------------
805
806 Let's slide gently into the new year.
807
808 - new: para_slider (not built automatically, type "make
809 para_slider" to build). A toy for those who always felt that
810 creating stream definitions is difficult. See screenshots,
811 README and FEATURES for more info.
812 - improved signal handling. Fixes server segfault on SIGHUP
813 for linux kernels newer than Aug 24 2004 and makes para_gui
814 race-free.
815 - reload database tool on SIGHUP
816 - improved help message for sl
817 - do not log "broken pipe" messages as errors. They are
818 perfectly ok.
819 - fix wrong error message on permission errors
820
821 -----------------------------------------
822 0.1.4 (2004-12-19) "tunneling transition"
823 -----------------------------------------
824
825 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
826 Hopefully, most of them got wiped out with this release. Some
827 enhancements went also in.
828
829 - improved error diagnostics for all commands
830 - stradd/picadd: overwrite previous contents if entry already
831 exists, rather than returning errors
832 - stradd: use current stream if invoked without args
833 - faster (and hopefully more stable) ogg-vorbis handling
834 - para_krell: reap children to avoid zombie-flooding in case
835 no server is running
836 - si: report also server pid
837 - server: don't busy-loop if dbtool reports only invalid files.
838 - gui: CTRL+C works again, fix stream_read command line option
839 - fix pic_add, hist
840 - fix mysql dbtool startup in case no database exists
841 - many small fixes and cleanups
842
843 ---------------------------------------
844 0.1.3: (2004-12-10) "vanishing inertia"
845 ---------------------------------------
846
847 Starting from this release, the database tools are integrated in the
848 server binary. This decreases server startup time, reduces code size
849 and speeds up database commands. However, the layout of the underlying
850 mysql database changed only slightly and 0.1.3 should be backwards
851 compatible in that respect.
852
853 Visible changes:
854
855 - If mysql is not detected at compile time, or fails to init
856 at runtime, fall back to the dopey database tool which should
857 always work.
858 - para_dbtool and dbtool.conf are gone. All mysql specific
859 options are read from server.conf and are prefixed by 'mysql_'.
860 - new command: cdt (change database tool)
861 - new command line option: dbtool (choose startup database tool)
862 - The name of current stream is now stored in the database,
863 so paraslash remembers its current stream when restarted.
864 - new command: csp (change stream and play)
865 - para_gui also reports current database tool and server uptime
866
867
868 -------------------------------------------
869 0.1.2: (2004-11-28) "spherical fluctuation"
870 -------------------------------------------
871
872 Point release before the big dbtool changes go in.
873
874 - dbtool: rename ca to cam (copy all meta data). It now also
875 copies numplayed and lastplayed time as well as the picture
876 id.
877 - fix endless-loop-bug caused by mp3 files with invalid header
878
879 -----------------------------------------
880 0.1.1: (2004-11-05) "floating atmosphere"
881 -----------------------------------------
882
883 - gkrellm plugin
884 - new dbtool command: mbox. Browse your sound-file collection
885 with your favorite mail reader.
886 - several small fixes
887
888 -------------------------------------
889 0.1.0: (2204-10-22) "rotating cortex"
890 -------------------------------------
891
892 - fix logging bug for loglevel > VERBOSE
893 - fix skip command
894 - correct timings for vbr mp3s
895 - modular audio format support
896 - ogg-vorbis support (experimental)
897 - new server option: autoplay
898
899 -----------------------------------------
900 0.0.99: (2004-07-25) "harmonic deviation"
901 -----------------------------------------
902
903 - rename projectname from icc to paraslash (play, archive, rate
904 and stream large audio sets happily)
905 - paraslash is no longer restricted to one particular audio
906 streaming software
907 - new dbtool commands (stradd, strq, strdel) for easy stream
908 managment w/o configuration file. That obsoletes stream_defs
909 file/config option for dbtool.
910 - picadd accepts jpeg data from stdin
911 - new server commands: ps (select previous stream), sc (song change)
912 - new default pictures for sdl_gui
913 - gui: new key_map option for binding commands and internal
914 functions to arbitrary keys, nice help screen, rip out
915 soundcard/linux specific stuff, avoid noise artefacts while jumping,
916 show silly logo on startup
917 - new executables: para_fade for fading volume, para_dbadm for
918 manipulating attributes
919 - cdb adds _all_ tables to mysql database
920 - revised and beautified documentation
921 - sample dbtool rewritten in C
922 - autoconf
923
924 ---------------------------------------------
925 0.0.98: (2003-12-26) "incremental smoothness"
926 ---------------------------------------------
927
928 - kick icecast in favour of poc. That removes some races and reduces
929 core code considerably.
930 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
931 give finer info on afs' status.
932 - gui can start decoder (see config options). Further new gui
933 commands: refresh (^L), jmp (F1-F10)
934 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
935 terminates gui. This fixes dead instances consuming memory
936 continuously.
937 - new dbtool command: verb for sending verbatim sql queries.
938 - fix pid_list races (by removing pid_list)
939 - codename funnies
940
941 --------------------
942 0.0.97: (2003-10-26)
943 --------------------
944
945 - installation prefix now defaults to /usr/local
946 - new commands for gui: snozze, sleep and reread config
947 - config file for gui and sdl_gui
948 - fix problems with filenames containing funny characters
949 (reported by Thomas Forell)
950 - improved signal handling for gui, now it rereads conf on SIGHUP
951 - new dbtool command: cdb (create database)
952 - switch from argtable to gengetopt
953 - major code cleanup and speed improvements
954 - fix several potential buffer overflows
955 - many small fixes and cleanups

959 -------------------
960
961 - easy stream_defs syntax
962 - sdl_gui can display images associated to the file being played
963 - Major feature enhancements for icc_gui including dynamic text

966 well as for invalid picture pointers
967 - fix long outstanding case sensitivity bug
968 - many small fixes and cleanups
969
970 -------------------
971 0.0.95 (2003-06-29)
972 -------------------
973
974 - sdl gui runs much faster
975 - new dbtool command: ca (copy attributes)
976 - count and display number of times the song has been played
977 - new feature: scoring
978 - command line options for sdl_gui

980 - decrease network traffic of stat
981 - fix zombie bug
982 - many small fixes and cleanups
983
984 -------------------

998 -------------------
999
1000 - colors for icc_gui
1001 - icc_gui sets volume directly (linux only)
1002 - proper locking that fixes some races
1003 - fix security bug that caused commands to be executed even
1004 with unsufficient permissions
1005 - new command: hup to make all servers reread their configuration file
1006 - icecast meta data streaming
1007 - many small fixes and cleanups
