[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 - Compiles cleanly also with llvm/clang.
20 - Corrupt mp3 files are handled more gracefully.
21 - sched: Optimized zero timeouts.
22
23 --------------------------------------
24 0.4.7 (2011-06-01) "infinite rollback"
25 --------------------------------------
26
27 The new ao writer, support for ssh RSA keys and a couple of other
28 enhancements.
29
30 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
31 platforms through the libao audio library.
32 - Support for RSA keys generated with ssh-keygen.
33 - configure: improved options for ogg/vorbis/speex.
34 - The git version reported by --version always matches HEAD.
35 - The autogen script detects the number of processors and
36 runs a parallel make if possible.
37 - Major cleanup of the crypto API.
38 - Documentation updates.
39
40 ------------------------------------------
41 0.4.6 (2011-03-31) "deterministic entropy"
42 ------------------------------------------
43
44 Lots of ogg/vorbis improvements, the new test suite, enhancements
45 for para_gui and a fair amount of other bug fixes.
46
47 - For DCCP/OGG streams the audio file header is only sent once
48 at the beginning of the stream rather than periodically
49 every five seconds. This reduces network traffic and the
50 FEC group size.
51 - The vorbis comment header is replaced by an empty dummy header
52 before the header is sent over the network. This also results in
53 less network traffic and smaller FEC groups.
54 - The new "test" make target allows to perform some sanity checks prior
55 to installing the package.
56 - ogg timing fixes and performance improvements
57 - Scheduler improvements
58 - Proper exit codes for para_write
59 - para_gui: New option --theme to select a startup theme. Several
60 other improvements and fixes.
61 - aacdec error message cleanups
62 - simplified color error handling
63
64 --------------------------------------------
65 0.4.5 (2010-12-17) "symmetric randomization"
66 --------------------------------------------
67
68 Bug fixes, internal cleanups and variable-sized FEC slices.
69
70 - Contains a fix for an invalid-free-bug in the ogg audio format
71 handler code.
72 - Switching off the DCCP sender works again.
73 - para_audiod handles crashes of para_server more robustly.
74 - Internal scheduler and writer cleanups.
75 - Reduced latency due to variable-sized FEC slices.
76 - Improved documentation and error diagnostics.
77 - The build of para_server is now optional, allowing the build
78 to succeed in case libosl is not installed.
79
80 ------------------------------------------
81 0.4.4 (2010-08-06) "persistent regularity"
82 ------------------------------------------
83
84 Support for yet another audio format, para_write improvements and
85 bug fixes.
86
87 - Support for the speex codec.
88 - Support for sample formats other than 16 bit little endian.
89 - error2.h is now created by a perl script which speeds up configure
90 considerably.
91 - Fix a bug in the aac decoder which could lead to segfaults in
92 para_filter/para_audiod.
93 - Fixes for autoconf-2.66.
94
95 ----------------------------------------
96 0.4.3 (2010-07-05) "imaginary radiation"
97 ----------------------------------------
98
99 Many improvements for the DCCP and the UDP transport, the new user
100 manual and the usual mix of bug fixes and internal improvements.
101
102 - FEC support for the DCCP sender (Gerrit Renker). The new
103 --dccp_max_slice_size, --dccp_data_slices_per_group and
104 --dccp_slices_per_group options can be used to set the FEC
105 parameters for the DCCP transport.
106 - DNS lookups for UDP targets (Gerrit Renker).
107 - The new user manual replaces the README, README.afs, REQUIREMENTS
108 and INSTALL documents.
109 - Fix an end-of-file detection bug in the oggdec filter.
110 - The new nonblock API.
111 - Both options of the oggdec filter have been removed.
112 - New debug mode for the internal scheduler.
113
114 ------------------------------------------
115 0.4.2 (2010-04-23) "associative expansion"
116 ------------------------------------------
117
118 It's been some time since the last release, but finally here is
119 paraslash-0.4.2. The bulk of the changes comes from the new buffer
120 tree API, but there are changes all over the tree. Mainly performance
121 and usability improvements, but also quite some bug fixes.
122
123 - The new buffer tree API.
124 - DCCP: Support for CCID negotiation (Gerrit Renker).
125 - UDP robustness fixes.
126 - The --bufsize option for mp3dec is gone as it no longer makes sense
127 for the new buffer tree API.
128 - Fix audible buffer underruns for wma streams.
129 - The alsa writer no longer prints meaningless underrun durations.
130 - audiod: Defaults work also for udp streams. If no filter is
131 given for an audio format that is received via upd, fecdec is
132 automatically added as the first filter (along with the decoder).
133
134 ---------------------------------------
135 0.4.1 (2009-12-22) "concurrent horizon"
136 ---------------------------------------
137
138 Support for another audio format, minor feature enhancements and lots of bug
139 fixes. All fixes that have been accumulated in the maint branch (in particular
140 those mentionened in the 0.3.6 release notes) appear in this release as well.
141
142 - wma support.
143 - new afh option: --human to activate human-readable output.
144 - new server/audiod option: --log-timing to print timing information.
145 - build system improvements.
146 - source code documentation updates.
147
148 -------------------------------------
149 0.3.6 (2009-12-07) "cubic continuity"
150 -------------------------------------
151
152 Quite a few bugs have been found and fixed since 0.3.5, so here's
153 another 0.3.x release. No new features.
154
155 - Always check return value of malloc().
156 - ogg vorbis/FEC: Do not write garbage after the audio file header.
157 - exit if root privileges could not be dropped.
158 - FEC: Fix computation of extra slices.
159 - oss: Fix check for empty input buffer.
160 - Avoid buffer underruns due to filter chain output buffer constraints.
161 - server: Fix assignment of afs_pid.
162 - Don't panic if the afs database contains unknown audio formats.
163 - http/dccp: Do not send the audio file header twice.
164 - FEC: Timing improvements.
165
166 ----------------------------------------------
167 0.4.0 (2009-11-10) "simultaneous independence"
168 ----------------------------------------------
169
170 Two significant changes which require the new version number: The
171 improved authentication dialog and the fact that the database code
172 has been moved to a library, libosl. To use the new version, you have
173 to generate new RSA keys, see INSTALL for details. A shell script is
174 provided for conversion of the 0.3 database to the new 0.4 format.
175
176 - stronger crypto for client authentication
177 - the database code has been moved to a library
178 - improved status item handling
179 - cleanup of the build system
180 - The "-V" option now also prints the git version
181 - the new parser-friendly listing mode for the ls and stat commands
182 - mandatory rc4 encryption
183 - major audio format handler cleanups
184 - (id3,...) tags are no longer stored as a combined string in the database
185 - new mood methods: artist_matches, title_matches, comment_matches,
186 album_matches, year_maches, year.
187
188 --------------------------------------------
189 0.3.5 (2009-09-21) "symplectic separability"
190 --------------------------------------------
191
192 Full client support for *BSD Unixes, complete re-write of the ogg
193 vorbis audio format handler, various improvements all over the place
194 and the usual mix of bugfixes. This release marks the end of the 0.3
195 series if no serious problems show up.
196
197 - the new oss writer (supported on *BSD and Linux)
198 - rewrite of the ogg vorbis audio format handler. It's
199 recommended to replace the chunk tables of existing ogg
200 vorbis files in the afs database by re-adding these files
201 with "add -f".
202 - support for netmask subsets (Gerrit Renker)
203 - the new prebuffer filter
204 - improved signal handling
205 - variable fec output buffer size
206 - improved FEC timing fixes audible buffer underruns in UDP mode
207 - --log_color actually works
208 - new ls option: -d (print dates as seconds after the epoch)
209 - update to gengetopt 2.22.2
210 - support for RSA keys of size > 512 bits
211 - new option "mixer_channel" for para_fade
212
213 -----------------------------------------
214 0.3.4 (2009-05-07) "elliptic inheritance"
215 -----------------------------------------
216
217 The new udp sender, forward error correction, colored logs and various
218 other improvements. As the udp sender does not depend on any special
219 libraries, it is built unconditionally.
220
221 - The udp sender replaces the ortp sender. The new code uses forward
222 error correction to protect against packet losses. Many thanks to
223 Gerrit Renker for providing ipv6 support.
224 - The default port for udp streaming now defaults to 8000, like
225 for the http and the dccp senders/receivers.
226 - Loglevels are now specified as symbolic names, e.g.
227 "--loglevel info".
228 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
229 - para_server/para_audiod: Color support for log messages.
230 - new options for mp3dec: --ignore-crc, --bufsize
231 - new audiod option: --config-file.
232 - gengetopt cleanups.
233 - Improved help/man pages: The documentation of para_audiod,
234 para_recv, para_filter and para_write now also contains
235 all options of the available receivers/filters/writers. The
236 man page of para_fade contains a description of the different
237 modes of operation.
238 - More source code documentation.
239 - vss timing fixes.
240
241 --------------------------------------------
242 0.3.3 (2008-12-01) "axiomatic perspectivity"
243 --------------------------------------------
244
245 Internal code cleanups, bug fixes, improved tag handling and the new
246 amplification filter.
247
248 - para_server uses the generic scheduling code.
249 - overhaul of the virtual streaming system.
250 - mp3: id3 version 2 support via libid3tag (optional)
251 - ogg: vorbis comment support.
252 - aac meta info support.
253 - mp3 audio format handler cleanups.
254 - new filter: "amp" to amplify the amplitude of the audio stream
255 - new status item/database entry: amplification. It is
256 used by the amp filter to pre-amplify the audio stream.
257 - fix a close-without-open bug in para_write.
258 - fix a bug in com_init() which was introduced in 0.3.2.
259 - better error diagnostics for para_client.
260
261 -----------------------------------------
262 0.3.2 (2008-04-11) "probabilistic parity"
263 -----------------------------------------
264
265 The new para_afh executable, scheduling and documentation improvements.
266
267 - new ls option: -lc (list chunk table)
268 - new executable: para_afh, the stand-alone audio file handler tool
269 - afs commands can send output more than SHMMAX (32MB on Linux). This
270 also reduces the memory usage of commands that produce large amounts
271 of output.
272 - major scheduler and audiod cleanups.
273 - more detailed and much nicer man pages.
274
275 ---------------------------------------
276 0.3.1 (2008-02-23) "liquid interaction"
277 ---------------------------------------
278
279 A mix of cleanups, bug fixes, improvements, and some new features. No
280 significant changes to the new database (osl) code, which is generally
281 a good sign.
282
283 - Share some similar/duplicate code between the http and the
284 dccp sender.
285 - Generic access control lists for paraslash senders.
286 - dccp sender: Access control lists, connection limiting and support
287 for the allow,deny,on,off,help sender commands.
288 - The default dccp port changed from 5001 to 8000 (suggested by
289 Gerrit Renker).
290 - para_server starts even if not all public keys could be loaded.
291 - Audiod performance improvements.
292 - fix a bug in the "off" command of the http sender.
293 - fix some fd and memory leaks.
294 - Update to gengetopt-2.22.
295
296 -------------------------------------
297 0.3.0 (2008-01-12) "solar saturation"
298 -------------------------------------
299
300 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
301
302
303 Usually one might expect lots of new features AND a big increase in size
304 for a major release like this.
305
306 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
307 ever. The decrease in size is mostly due to the removal of some
308 graphical tools (which were only quick hacks anyway). But also the
309 fact that the mysql code is gone cuts down the size a bit.
310
311 Being independent of mysql comes at a cost: The fact that paraslash
312 now contains its own database (the object storage layer, osl) increases
313 the (stripped) binary size of para_server by ~50K on i386.
314
315 - no more restrictions on unique basenames.
316 - independent of mysql: The new self-contained object
317 storage layer (osl) replaces the mysql database.
318 - New executable para_fsck: Check integrity of osl tables.
319 - Lyrics support.
320 - Reliable audio file move/rename detection.
321 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
322 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
323 Solaris (sparc64).
324 - the new osl-based audio file selector (afs) replaces the random,
325 the playlist and the mysql selector of paraslash-0.2.x.
326 - IPv6 support (thanks to Gerrit Renker).
327 - paraslash-0.2.x streams are now called "moods". Writing
328 0.3.x-mood definitions should be both easier and more
329 powerful than writing 0.2.x-stream definitions.
330 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
331 been removed. The world is a better place without them. However,
332 para_gui is still there.
333 - afs tracks audio file selection also in playlist mode.
334 - few easy-to-use afs commands replace the many not-so-easy-to-use
335 mysql commands (and are available also in playlist mode).
336 - Improved error subsystem.
337 - The earth-shaking new logo.
338
339 -----------------------------------------
340 0.2.17 (2007-11-20) "isotropic threshold"
341 -----------------------------------------
342
343 Mainly bugfixes and cleanups in this version which marks the end of
344 the 0.2.x series if no serious bugs show up after the release.
345
346 - mysql_selector: fix a locking bug.
347 - universal chunk queueing.
348 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
349 to Gerrit Renker).
350 - be more carful wrt. signed vs. unsigned argument passing.
351 - cleanup error.h and fix some references to invalid error
352 codes.
353 - update to gengetopt-2.21.
354 - update to ortp-0.13.1.
355 - autoconf: extend checks for headers, library functions and
356 compiler characteristics.
357 - Fix streaming of large mp3 files.
358 - Fix an off-by-one bug in playlist handling.
359
360 --------------------------------------
361 0.2.16 (2007-04-05) "neural discharge"
362 --------------------------------------
363
364 The main change in this release is the major audio format handler
365 cleanup which removes some similar/duplicate code and makes it easier
366 to implement plugins for other audio formats. Of course, the usual mix
367 of other improvements/changes/bugfixes also made it into the release.
368
369 - simplified audio format handlers (most of the handling functions
370 were moved one layer up to the virtual streaming system).
371 - para_server uses mmap to read audio files
372 - repositioning of mp3 streams is much faster, in particular for
373 jumping near the end of large mp3 files.
374 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
375 and AFS_WRITE.
376 - fix a bug in para_filter that caused decoding of aac files
377 to start only after a few seconds.
378 - fix osx_writer hangs
379 - simplified dccp code (thanks to Gerrit Renker)
380 - the compress filter works also on big endian systems (ppc)
381
382 -----------------------------------------
383 0.2.15 (2007-02-16) "inductive resonance"
384 -----------------------------------------
385
386 Minor improvements, more documentation and a bunch of bug fixes.
387
388 - para_server: The server.users file is only read once on server
389 startup rather than for each connection
390 - mp3dec: Fix decoding of corrupt mp3 files
391 - afs (audio file sender) is now called vss (virtual streaming
392 system). Consequently, the permission flags specified in
393 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
394 become VSS_READ and VSS_WRITE respectively.
395 - para_audiod/para_filter: Fix a bug that caused the last chunk
396 of audio data not being written under certain circumstances
397 - audiod: compute the difference of server time and local time
398 correctly
399 - para_server/para_audiod: Fix some memory leaks
400 - documentation improvements
401 - configure.ac: fix checks for para_krell
402 - new man pages
403
404 -------------------------------------------
405 0.2.14 (2006-10-15) "transient singularity"
406 -------------------------------------------
407
408 The only major enhancement of this version is the osx writer which completes
409 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
410 until now for reasons beyond the scope of this changelog entry.
411
412 - new output plugin for Mac Os: the osx writer
413 - rename configure command line options from --enable-xxx-headers to
414 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
415 - configure: new command line options: --with-mad-headers,
416 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
417 - some robustness fixes
418 - dymamic audio format recognition for audiod
419 - para_server: new command line option: --autoplay_delay
420 - para_audiod: new command line option: --clock_diff_count
421
422 ---------------------------------------
423 0.2.13 (2006-07-14) "sonic convolution"
424 ---------------------------------------
425
426 A bunch of new features and core changes.
427
428 - the new paraslash scheduler, short and sweet.
429 - Support for m4a/mp4 files via the new aac audio format
430 handler/filter (requires libfaad).
431 - each writer has its own command line parser, just like
432 para_recv and para_filter.
433 - para_client and para_audioc use the error subsystem
434 - writers are integrated in para_audiod (currently linux-only)
435 - para_client is integrated in para_audiod
436 - random/playlist selector: improved info strings
437 - new audiod commands: tasks, kill
438 - update to libortp-0.10.1
439 - para_fade: wake time defaults to 8 hours from now
440 - update to autoconf-2.60
441
442
443 ------------------------------------------
444 0.2.12 (2006-05-12) "oriented abstraction"
445 ------------------------------------------
446
447 Many user-visible changes in this release and lots of new
448 features:
449
450
451 - the new optional dccp sender/receiver. It uses the datagram
452 congestion control protocol. You'll need a fairly new kernel
453 for this.
454 - paraslash works on Mac OS X (thanks to Gerd Becker)
455 - para_play renamed to para_write
456 - modular output plugin design (writers) for para_write
457 - new file_writer output plugin for para_write
458 - compress filter speed improvements
459 - update to libortp-0.9.1
460 - update to gengetopt-2.17rc
461 - para_client no longer depends on libreadline (as the
462 code for the interactive mode was removed).
463 - gcc-2-95 is no longer a supported compiler. It may still
464 work, but it gets no more testing.
465 - the tarball no longer contains the screenshot images which
466 reduces its size quite a bit.
467 - configure: new command line options: --enable-mysql-headers
468 and --enable-mysql-libs
469
470 ------------------------------------
471 0.2.11 (2006-03-11) "atomic duality"
472 ------------------------------------
473
474 Here it is, the first paraslash release developed with git. There
475 are fairly many user-visible changes in this release. As two out of
476 the three "database tools" of paraslash don't use a database at all,
477 they are now called "audio file selectors" instead.
478
479
480 - the cdt command (change database tool) becomes chs (change
481 selector)
482 - no more colon separators: The syntax of some options of
483 para_audiod and para_filter have changed. Use --help for
484 more info (and some examples).
485 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
486 - switch from cvs to git (should've done that earlier)
487 - the new ipc subsystem
488 - new audio file selector: playlist
489 - para_server: the dopey selector is now called "random",
490 and is the default selector. Use the --selector option to
491 choose another selector at startup, or the chs command to
492 change the selector at runtime.
493 - X86_64 fixes (thanks to Steffen Klassert)
494 - para_play fixes
495
496
497 --------------------------------------
498 0.2.10 (2006-02-17) "cyclic attractor"
499 --------------------------------------
500
501 Huge documentation update, a scrollable window for para_gui, ortp
502 improvements, and of course many small fixes not mentioned here.
503 The diffstat below is rather misleading as most insertions are due
504 to the new source documentation.
505
506 - autoconf cleanup
507 - para_server also uses the new error subsystem
508 - lots of new documentation (UTSL)
509 - gui improvements:
510 - keysyms for cursor keys and for next/previous page keys
511 - scrollable output window
512 - new internal commands: scroll up/down, page up/down
513 - fix color of command output.
514 - ortp: the --chunk_time and --header flags are no longer needed
515 for para_recv/para_audiod as this information is now encoded in
516 each rtp packet sent by para_server.
517
518
519 -------------------------------------------
520 0.2.9 (2006-01-24) "progressive turbulence"
521 -------------------------------------------
522
523 Internal audiod receivers/filters, the new error subsystem and
524 a lot of small improvements.
525
526 - para_recv and para_filter are integrated into the para_audiod
527 binary, i.e. audiod no longer spawns a new process for
528 each receiver/filter. As para_recv and para_filter might be
529 useful as standalone programs, they still get built (linked
530 against the same object files that are also used for audiod).
531 - further ortp timing improvements should reduce the CPU usage
532 of the ortp receiver.
533 - improved audio grabbing. The 'grab' command of para_audiod
534 has its own set of command line options. Read the output of
535 "para_audioc help grab" for more info.
536 - oggdec: configurable input prebuffer size.
537 - the new error subsystem gives better error diagnostics
538 and reduces code size.
539
540
541 -----------------------------------------
542 0.2.8 (2006-01-02) "dynamic accumulation"
543 -----------------------------------------
544
545 The new modular filter design and the para_play-hangs bugfix.
546
547 - new executable: para_filter. It combines para_mp3dec,
548 para_oggdec and para_compress. It also adds a further filter
549 type, wav, that just inserts a wave header at the desired point
550 of the filter chain. All 'piping' is done in-memory (i.e. no
551 read/write operations are used).
552 - para_play: fix a stupid bug that caused it to hang under
553 certain circumstances.
554
555
556 -------------------------------------------
557 0.2.7 (2006-12-27) "transparent invariance"
558 -------------------------------------------
559
560 Not many user-visible changes but a fair amount of internal improvements.
561
562
563 - The http sender buffers data if it can not be sent
564 out immediately (because the socket is not writable). This
565 should prevent para_server from shutting down the connection
566 too early on a loaded network.
567 - para_play also prebuffers data if it is told to start at a
568 future time by the --start_time option.
569 - The return of para_recv: It combines para_ortp_recv and
570 para_http_recv. Use the --receiver option to switch between
571 the two. para_recv builds without libortp, but contains
572 only the http receiver in this case.
573 - update to ortp 0.8.1. As this ortp release contains incompatible
574 changes, para_recv-0.2.7 won't link against older ortp libs.
575 - improved ortp timings.
576 - use of gcc-extensions that #define away for non-gcc and
577 gcc < 3.0.
578
579
580 -------------------------------------------
581 0.2.6 (2005-10-29) "recursive compensation"
582 -------------------------------------------
583
584 Transparent session encryption (uses openssl's Alleged RC4 cipher),
585 the internal find command and several other improvements and cleanups.
586
587 - Encrypt the session if encryption is requested by the client
588 (default for para_client 0.2.6). This is backwards
589 compatible, so older clients can still connect to para_server
590 0.2.6. Use the new client option --plain to request an
591 uncrypted session (off by default, must be set to on in
592 order to connect to para_server 0.2.x with 0 <= x <= 5).
593 - para_server uses an internal function to locate audio files
594 rather than calling find(1). The server option
595 --mysql_audio_file_dir replaces --mysql_find_cmd.
596 - documentation update
597 - man pages
598 - header file cleanup
599 - para_client code cleanup
600 - para_gui: faster display of output of display commands
601
602
603 ------------------------------------------
604 0.2.5 (2005-10-13) "aggressive resolution"
605 ------------------------------------------
606
607 This release adds internal senders, i.e. no more external programs are
608 spawned for sending out the audio data. There are two different senders
609 available: The http sender and the ortp sender (former para_send which
610 is no longer needed).
611
612 The new sender code has a plugin-like design so it can be easily
613 extended should there be be any future need for supporting another
614 network streaming protocol. All senders are completely independent of
615 each other. In particular, the http and the ortp sender can operate
616 in parallel.
617
618 - new server command: sender to control senders at runtime.
619 Read the output of "para_server -h" and "para_client help
620 sender" for more information.
621 - para_recv renamed to para_ortp_recv
622 - new executable: para_http_recv, a simple command line
623 http receiver.
624 - major afs/mp3/ogg code simplifications due to internal
625 senders.
626 - ogg timing improvements
627 - fix several minor memory leaks (found by valgrind)
628 - empty stream definitions work again
629 - com_ne(): ignore errors on remove
630 - audiod: fix segfault on server restart
631
632
633 ---------------------------------------
634 0.2.4 (2005-09-21) "toxic anticipation"
635 ---------------------------------------
636
637 Several small improvements, fixes and the new grab command.
638
639 - audiod:
640 - new command: "grab" to grab the output of the stream reader
641 or any filters. Read the output of "para_audioc help grab"
642 for more information.
643 - fix memory leak
644 - code cleanup
645 - audioc: new command line option: --bufsize to specify a
646 buffer size different from the default size 8192.
647 - improved error diagnostics for para_play.
648 - new configure option: --enable-ssldir so search for openssl in
649 non-standard places
650 - sdl_gui: Make it look nice again for 1024x768
651 - server: report total size of memory allocated with sbrk by malloc,
652 new command line option: --announce_time
653
654
655 -----------------------------------------
656 0.2.3 (2005-09-01) "hydrophilic movement"
657 -----------------------------------------
658
659 Two new executables and major feature enhancements.
660
661 - audiod filters: It is now possible to specify arbitrary many
662 (including none) filters for each supported audio
663 format. This can be used e.g. for normalizing volume,
664 transforming or grabbing the audio stream, or for using
665 visualizers. Read the output of "para_audiod -h" for the
666 syntax of the new --filter_cmd option.
667 - new executable: para_play, a tiny alsa player. It
668 can play wave files or raw pcm (16 bit little endian)
669 from stdin.
670 - new executable: para_compress, a dynamic range compressor
671 intended to keep audio output at a consistent volume. Derived
672 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
673 - audiod: New option: --stream_delay. This can be used in
674 a local network to syncronize the audio output of all
675 clients that play the same stream.
676
677
678 ------------------------------------------
679 0.2.2 (2005-08-19) "tangential excitation"
680 ------------------------------------------
681
682 Mostly internal changes in this release, but also some new commands
683 for the mysql database tool.
684
685 - cleanup exec.c, fix para_exec bug
686 - compile time loglevel (log messages below the given level
687 won't be compiled in, which reduces the size of the
688 resulting binaries)
689 - new log macros that shorten the size of the source code.
690 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
691 to send only zeros. With this workaround, para_audioc works
692 again.
693 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
694 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
695 (new entry), "snp" (set numplayed). Read the manual for more
696 information.
697
698
699 ---------------------------------------
700 0.2.1 (2005-08-15) "surreal experience"
701 ---------------------------------------
702
703 Here comes paraslash-0.2.1. It contains a couple of new features and,
704 surprise, only minor bug fixes.
705
706 - kill noisy mp3 debug message
707 - cleanup of the build system
708 - para_server and para_client directly use the crypto routines
709 of the openssl library rather than invoking the openssl command
710 line utitlity
711 - server/audiod: new option --user to switch to the given user
712 when invoked as root. Read the output of "para_server -h" for
713 more information.
714 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
715 status. Default: "para_audioc stat"
716 - sdl_gui: new option --pic_cmd to be used to download the picture.
717 Default: "para_client pic"
718 - audiod: 5 slots ought to be enough for everybody
719 - audiod: new status item: Uptime, kill hup command
720
721
722
723 ------------------------------------------
724 0.2.0 (2005-08-06) "distributed diffusion"
725 ------------------------------------------
726
727 After several month of increased development activity, paraslash-0.2.0
728 has arrived. It contains many new features and is much more
729 self-contained than the old 0.1.x series. Enjoy!
730
731
732 - para_server: fix hang on song change and crash on sighup.
733 Speed up mysql queries. The DIR_LIKE macro is gone.
734 - new executables: para_audiod, the local audio daemon that
735 starts playback (uses SCM_CREDENTIALS socket magic) and
736 para_audioc, the corresponding client.
737 - new executables: para_mp3dec/para_oggdec, two really teensy
738 decoders. para_mp3dec is based on libmad, para_oggdec requires
739 libvorbisfile.
740 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
741 they are now called para_send and para_recv respectively.
742 - documentation updates
743 - para_gui is themable. For now there is the default theme that
744 looks as before and the simple theme: blue and easy.
745 - gui: audio streaming is now handled by audiod. Time display shows
746 playback time rather than streaming time
747 - slider: update to libzmw-0.2.0
748 - para_krell: fix crash on server shutdown
749 - switch from gzip to bzip2
750
751
752 ----------------------------------------
753 0.1.7 (2005-04-18) "melting penetration"
754 ----------------------------------------
755
756 The main change in this release is clearly the oggvorbis rewrite,
757 but there are also lots of smaller changes. If you intend to use both
758 the mp3 and the ogg plugin, it is recommended to use software mixing,
759 e.g. the dmix plugin which is provided by ALSA.
760
761 - new executables: para_ovsend and para_ovrecv for sending/receiving
762 oggvorbis files via rtp. Requires the open rtp library. Get it at
763 http://www.linphone.org/ortp/
764 - rewrite of the ogg_vorbis core code
765 - configure detects libzmw and, if detected, includes
766 para_slider to the list of binaries to be built by make
767 - server stream writers read from their associated fifo rather
768 than from stdin
769 - slider: two new sliders, lastplayed and numplayed
770 - fix nasty double free bug which caused random segfaults in case of
771 mp3 files with invalid header information
772 - gui: new command line option: --stream_timeout=seconds to
773 deactivate a slot if it is idle for that many seconds (default=`5')
774 - diffstats
775
776
777 ---------------------------------------
778 0.1.6 (2005-03-05) "asymptotic balance"
779 ---------------------------------------
780
781 Only little user-visible changes in this release. Mainly bugfixes and
782 core code cleanup. This is probably the most stable version ever if you
783 stick to mp3...
784
785 - fix several memory leaks
786 - rename default name of mysql database from "music" to "paraslash".
787 Use para_server's --mysql_database option if you do not want to
788 rename your old database.
789 - rework ogg vorbis code
790 - make update command work on mysql servers with LOCAL_INFILE
791 disabled
792 - gui: improved stream I/O (slots)
793 - simplified audio format API
794 - para_pob_ogg is gone
795
796 ------------------------------------
797 0.1.5 (2004-12-31) "opaque eternity"
798 ------------------------------------
799
800 Let's slide gently into the new year.
801
802 - new: para_slider (not built automatically, type "make
803 para_slider" to build). A toy for those who always felt that
804 creating stream definitions is difficult. See screenshots,
805 README and FEATURES for more info.
806 - improved signal handling. Fixes server segfault on SIGHUP
807 for linux kernels newer than Aug 24 2004 and makes para_gui
808 race-free.
809 - reload database tool on SIGHUP
810 - improved help message for sl
811 - do not log "broken pipe" messages as errors. They are
812 perfectly ok.
813 - fix wrong error message on permission errors
814
815 -----------------------------------------
816 0.1.4 (2004-12-19) "tunneling transition"
817 -----------------------------------------
818
819 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
820 Hopefully, most of them got wiped out with this release. Some
821 enhancements went also in.
822
823 - improved error diagnostics for all commands
824 - stradd/picadd: overwrite previous contents if entry already
825 exists, rather than returning errors
826 - stradd: use current stream if invoked without args
827 - faster (and hopefully more stable) ogg-vorbis handling
828 - para_krell: reap children to avoid zombie-flooding in case
829 no server is running
830 - si: report also server pid
831 - server: don't busy-loop if dbtool reports only invalid files.
832 - gui: CTRL+C works again, fix stream_read command line option
833 - fix pic_add, hist
834 - fix mysql dbtool startup in case no database exists
835 - many small fixes and cleanups
836
837 ---------------------------------------
838 0.1.3: (2004-12-10) "vanishing inertia"
839 ---------------------------------------
840
841 Starting from this release, the database tools are integrated in the
842 server binary. This decreases server startup time, reduces code size
843 and speeds up database commands. However, the layout of the underlying
844 mysql database changed only slightly and 0.1.3 should be backwards
845 compatible in that respect.
846
847 Visible changes:
848
849 - If mysql is not detected at compile time, or fails to init
850 at runtime, fall back to the dopey database tool which should
851 always work.
852 - para_dbtool and dbtool.conf are gone. All mysql specific
853 options are read from server.conf and are prefixed by 'mysql_'.
854 - new command: cdt (change database tool)
855 - new command line option: dbtool (choose startup database tool)
856 - The name of current stream is now stored in the database,
857 so paraslash remembers its current stream when restarted.
858 - new command: csp (change stream and play)
859 - para_gui also reports current database tool and server uptime
860
861
862 -------------------------------------------
863 0.1.2: (2004-11-28) "spherical fluctuation"
864 -------------------------------------------
865
866 Point release before the big dbtool changes go in.
867
868 - dbtool: rename ca to cam (copy all meta data). It now also
869 copies numplayed and lastplayed time as well as the picture
870 id.
871 - fix endless-loop-bug caused by mp3 files with invalid header
872
873 -----------------------------------------
874 0.1.1: (2004-11-05) "floating atmosphere"
875 -----------------------------------------
876
877 - gkrellm plugin
878 - new dbtool command: mbox. Browse your sound-file collection
879 with your favorite mail reader.
880 - several small fixes
881
882 -------------------------------------
883 0.1.0: (2204-10-22) "rotating cortex"
884 -------------------------------------
885
886 - fix logging bug for loglevel > VERBOSE
887 - fix skip command
888 - correct timings for vbr mp3s
889 - modular audio format support
890 - ogg-vorbis support (experimental)
891 - new server option: autoplay
892
893 -----------------------------------------
894 0.0.99: (2004-07-25) "harmonic deviation"
895 -----------------------------------------
896
897 - rename projectname from icc to paraslash (play, archive, rate
898 and stream large audio sets happily)
899 - paraslash is no longer restricted to one particular audio
900 streaming software
901 - new dbtool commands (stradd, strq, strdel) for easy stream
902 managment w/o configuration file. That obsoletes stream_defs
903 file/config option for dbtool.
904 - picadd accepts jpeg data from stdin
905 - new server commands: ps (select previous stream), sc (song change)
906 - new default pictures for sdl_gui
907 - gui: new key_map option for binding commands and internal
908 functions to arbitrary keys, nice help screen, rip out
909 soundcard/linux specific stuff, avoid noise artefacts while jumping,
910 show silly logo on startup
911 - new executables: para_fade for fading volume, para_dbadm for
912 manipulating attributes
913 - cdb adds _all_ tables to mysql database
914 - revised and beautified documentation
915 - sample dbtool rewritten in C
916 - autoconf
917
918 ---------------------------------------------
919 0.0.98: (2003-12-26) "incremental smoothness"
920 ---------------------------------------------
921
922 - kick icecast in favour of poc. That removes some races and reduces
923 core code considerably.
924 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
925 give finer info on afs' status.
926 - gui can start decoder (see config options). Further new gui
927 commands: refresh (^L), jmp (F1-F10)
928 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
929 terminates gui. This fixes dead instances consuming memory
930 continuously.
931 - new dbtool command: verb for sending verbatim sql queries.
932 - fix pid_list races (by removing pid_list)
933 - codename funnies
934
935 --------------------
936 0.0.97: (2003-10-26)
937 --------------------
938
939 - installation prefix now defaults to /usr/local
940 - new commands for gui: snozze, sleep and reread config
941 - config file for gui and sdl_gui
942 - fix problems with filenames containing funny characters
943 (reported by Thomas Forell)
944 - improved signal handling for gui, now it rereads conf on SIGHUP
945 - new dbtool command: cdb (create database)
946 - switch from argtable to gengetopt
947 - major code cleanup and speed improvements
948 - fix several potential buffer overflows
949 - many small fixes and cleanups
950
951 -------------------
952 0.0.96 (2003-08-30)
953 -------------------
954
955 - easy stream_defs syntax
956 - sdl_gui can display images associated to the file being played
957 - Major feature enhancements for icc_gui including dynamic text
958 placement and the top/bottom window design
959 - vrfy/clean now also checks for NULL values in attributes as
960 well as for invalid picture pointers
961 - fix long outstanding case sensitivity bug
962 - many small fixes and cleanups
963
964 -------------------
965 0.0.95 (2003-06-29)
966 -------------------
967
968 - sdl gui runs much faster
969 - new dbtool command: ca (copy attributes)
970 - count and display number of times the song has been played
971 - new feature: scoring
972 - command line options for sdl_gui

974 - decrease network traffic of stat
975 - fix zombie bug
976 - many small fixes and cleanups
977
978 -------------------
979 0.0.94 (2003-05-04)
980 -------------------
981
982 - new server command: ns (next stream)

992 -------------------
993
994 - colors for icc_gui
995 - icc_gui sets volume directly (linux only)
996 - proper locking that fixes some races
997 - fix security bug that caused commands to be executed even
998 with unsufficient permissions
999 - new command: hup to make all servers reread their configuration file
