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

824 - config file for gui and sdl_gui
825 - fix problems with filenames containing funny characters
826 (reported by Thomas Forell)
827 - improved signal handling for gui, now it rereads conf on SIGHUP
828 - new dbtool command: cdb (create database)
829 - switch from argtable to gengetopt
830 - major code cleanup and speed improvements
831 - fix several potential buffer overflows
