1 -------------------------------------------
2 0.4.11 (to be announced "mutual diversity")
3 -------------------------------------------
4
5 ------------------------------------------
6 0.4.10 (2012-03-30) "heterogeneous vacuum"
7 ------------------------------------------
8
9 Nothing earth-shaking in this release, but quite a few usability
10 improvements and the usual mix of cleanups and fixes.
11
12 - The --no_default_filters option of para_filter has been
13 deprecated. It still works but has no effect and will be
14 removed in the next version.
15 - para_gui now prints also the stderr output of the executing
16 command in the bottom window.
17 - Cleanup and consolidation of the various wrappers for
18 write(), writev(), send() and friends.
19 - The obscure error messages on mmap() failures have been
20 replaced by meaningful messages. This affects mainly
21 para_afh.
22 - para_audioc: Cleanups and memory leak fixes.
23 - Test 0004-server no longer fails if para_server is not
24 being built.
25 - New configure options: --with-id3tag-{headers,libs}.
26
27 -------------------------------------
28 0.4.9 (2011-12-06) "hybrid causality"
29 -------------------------------------
30
31 Support for another audio format, interactive mode for para_client
32 and para_audiod and many small improvements/fixes all over the place.
33
34 - Support for flac, the free lossless audio codec.
35 - Fix for an endless loop in the mp3 decoder for certain
36 (corrupt) mp3 files.
37 - When executed without specifying a command, para_client
38 and para_audioc start an interactive shell (requires
39 libreadline being installed). The interactive mode offers
40 full tab completion and command line history.
41 - autogen.sh now detects a distcc setup and adjusts the
42 parameter for the -j option of make accordingly.
43 - Shared memory areas are no longer restricted to 64K. We now
44 detect the maximal size of a shared memory area at runtime.
45 - cleanup of the internal uptime API.
46 - para_server prefaults the mmapped audio file to avoid
47 delays on slow media.
48 - A new test for the test-suite that exercises the
49 communication between para_server and para_audiod.
50 - The alsa writer eats up less CPU cycles when configured to
51 use the DMIX plugin.
52 - Simplified and unified receiver code.
53 - Makefile cleanups.
54 - Commands which print a list of matching audio files now
55 emit a meaningful error message if no audio file matched the
56 given pattern(s).
57
58 --------------------------------------
59 0.4.8 (2011-08-19) "nested assignment"
60 --------------------------------------
61
62 Gcrypt support, the overhauled osx writer and regex format specifiers
63 are the highlights of this release.
64
65 - support for libgcrypt as a drop-in replacement for openssl.
66 Run configure --enable-cryptolib=gcrypt to link against
67 libgcrypt. The two crypto implementations are compatible to
68 each other, i.e. a para_client executable linked against
69 gcrypt can connect to para_server linked against libssl
70 and vice versa.
71 - Rewrite of the osx writer (output plugin for Mac OS).
72 - audiod: The format specifier for receivers, filters and
73 writers is now treated as a regular expression. This allows
74 to replace 5 lines in the config file (one for each audio
75 format) by one single line. See the manual for details.
76 - The *.cmdline.[ch] files are no longer contained in the released
77 tarballs. This reduces the size of the tarballs but requires
78 gengetopt to build the tarball.
79 - Compiles cleanly also with llvm/clang.
80 - Corrupt mp3 files are handled more gracefully.
81 - The alsa writer uses poll fds instead of computing timeouts.
82 - Cleanup of the generic writer API.
83 - sched: Optimized zero timeouts.
84 - vss timeout cleanups.
85 - oggdec fixes and improvements.
86
87 --------------------------------------
88 0.4.7 (2011-06-01) "infinite rollback"
89 --------------------------------------
90
91 The new ao writer, support for ssh RSA keys and a couple of other
92 enhancements.
93
94 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
95 platforms through the libao audio library.
96 - Support for RSA keys generated with ssh-keygen.
97 - configure: improved options for ogg/vorbis/speex.
98 - The git version reported by --version always matches HEAD.
99 - The autogen script detects the number of processors and
100 runs a parallel make if possible.
101 - Major cleanup of the crypto API.
102 - Documentation updates.
103
104 ------------------------------------------
105 0.4.6 (2011-03-31) "deterministic entropy"
106 ------------------------------------------
107
108 Lots of ogg/vorbis improvements, the new test suite, enhancements
109 for para_gui and a fair amount of other bug fixes.
110
111 - For DCCP/OGG streams the audio file header is only sent once
112 at the beginning of the stream rather than periodically
113 every five seconds. This reduces network traffic and the
114 FEC group size.
115 - The vorbis comment header is replaced by an empty dummy header
116 before the header is sent over the network. This also results in
117 less network traffic and smaller FEC groups.
118 - The new "test" make target allows to perform some sanity checks prior
119 to installing the package.
120 - ogg timing fixes and performance improvements
121 - Scheduler improvements
122 - Proper exit codes for para_write
123 - para_gui: New option --theme to select a startup theme. Several
124 other improvements and fixes.
125 - aacdec error message cleanups
126 - simplified color error handling
127
128 --------------------------------------------
129 0.4.5 (2010-12-17) "symmetric randomization"
130 --------------------------------------------
131
132 Bug fixes, internal cleanups and variable-sized FEC slices.
133
134 - Contains a fix for an invalid-free-bug in the ogg audio format
135 handler code.
136 - Switching off the DCCP sender works again.
137 - para_audiod handles crashes of para_server more robustly.
138 - Internal scheduler and writer cleanups.
139 - Reduced latency due to variable-sized FEC slices.
140 - Improved documentation and error diagnostics.
141 - The build of para_server is now optional, allowing the build
142 to succeed in case libosl is not installed.
143
144 ------------------------------------------
145 0.4.4 (2010-08-06) "persistent regularity"
146 ------------------------------------------
147
148 Support for yet another audio format, para_write improvements and
149 bug fixes.
150
151 - Support for the speex codec.
152 - Support for sample formats other than 16 bit little endian.
153 - error2.h is now created by a perl script which speeds up configure
154 considerably.
155 - Fix a bug in the aac decoder which could lead to segfaults in
156 para_filter/para_audiod.
157 - Fixes for autoconf-2.66.
158
159 ----------------------------------------
160 0.4.3 (2010-07-05) "imaginary radiation"
161 ----------------------------------------
162
163 Many improvements for the DCCP and the UDP transport, the new user
164 manual and the usual mix of bug fixes and internal improvements.
165
166 - FEC support for the DCCP sender (Gerrit Renker). The new
167 --dccp_max_slice_size, --dccp_data_slices_per_group and
168 --dccp_slices_per_group options can be used to set the FEC
169 parameters for the DCCP transport.
170 - DNS lookups for UDP targets (Gerrit Renker).
171 - The new user manual replaces the README, README.afs, REQUIREMENTS
172 and INSTALL documents.
173 - Fix an end-of-file detection bug in the oggdec filter.
174 - The new nonblock API.
175 - Both options of the oggdec filter have been removed.
176 - New debug mode for the internal scheduler.
177
178 ------------------------------------------
179 0.4.2 (2010-04-23) "associative expansion"
180 ------------------------------------------
181
182 It's been some time since the last release, but finally here is
183 paraslash-0.4.2. The bulk of the changes comes from the new buffer
184 tree API, but there are changes all over the tree. Mainly performance
185 and usability improvements, but also quite some bug fixes.
186
187 - The new buffer tree API.
188 - DCCP: Support for CCID negotiation (Gerrit Renker).
189 - UDP robustness fixes.
190 - The --bufsize option for mp3dec is gone as it no longer makes sense
191 for the new buffer tree API.
192 - Fix audible buffer underruns for wma streams.
193 - The alsa writer no longer prints meaningless underrun durations.
194 - audiod: Defaults work also for udp streams. If no filter is
195 given for an audio format that is received via upd, fecdec is
196 automatically added as the first filter (along with the decoder).
197
198 ---------------------------------------
199 0.4.1 (2009-12-22) "concurrent horizon"
200 ---------------------------------------
201
202 Support for another audio format, minor feature enhancements and lots of bug
203 fixes. All fixes that have been accumulated in the maint branch (in particular
204 those mentionened in the 0.3.6 release notes) appear in this release as well.
205
206 - wma support.
207 - new afh option: --human to activate human-readable output.
208 - new server/audiod option: --log-timing to print timing information.
209 - build system improvements.
210 - source code documentation updates.
211
212 -------------------------------------
213 0.3.6 (2009-12-07) "cubic continuity"
214 -------------------------------------
215
216 Quite a few bugs have been found and fixed since 0.3.5, so here's
217 another 0.3.x release. No new features.
218
219 - Always check return value of malloc().
220 - ogg vorbis/FEC: Do not write garbage after the audio file header.
221 - exit if root privileges could not be dropped.
222 - FEC: Fix computation of extra slices.
223 - oss: Fix check for empty input buffer.
224 - Avoid buffer underruns due to filter chain output buffer constraints.
225 - server: Fix assignment of afs_pid.
226 - Don't panic if the afs database contains unknown audio formats.
227 - http/dccp: Do not send the audio file header twice.
228 - FEC: Timing improvements.
229
230 ----------------------------------------------
231 0.4.0 (2009-11-10) "simultaneous independence"
232 ----------------------------------------------
233
234 Two significant changes which require the new version number: The
235 improved authentication dialog and the fact that the database code
236 has been moved to a library, libosl. To use the new version, you have
237 to generate new RSA keys, see INSTALL for details. A shell script is
238 provided for conversion of the 0.3 database to the new 0.4 format.
239
240 - stronger crypto for client authentication
241 - the database code has been moved to a library
242 - improved status item handling
243 - cleanup of the build system
244 - The "-V" option now also prints the git version
245 - the new parser-friendly listing mode for the ls and stat commands
246 - mandatory rc4 encryption
247 - major audio format handler cleanups
248 - (id3,...) tags are no longer stored as a combined string in the database
249 - new mood methods: artist_matches, title_matches, comment_matches,
250 album_matches, year_maches, year.
251
252 --------------------------------------------
253 0.3.5 (2009-09-21) "symplectic separability"
254 --------------------------------------------
255
256 Full client support for *BSD Unixes, complete re-write of the ogg
257 vorbis audio format handler, various improvements all over the place
258 and the usual mix of bugfixes. This release marks the end of the 0.3
259 series if no serious problems show up.
260
261 - the new oss writer (supported on *BSD and Linux)
262 - rewrite of the ogg vorbis audio format handler. It's
263 recommended to replace the chunk tables of existing ogg
264 vorbis files in the afs database by re-adding these files
265 with "add -f".
266 - support for netmask subsets (Gerrit Renker)
267 - the new prebuffer filter
268 - improved signal handling
269 - variable fec output buffer size
270 - improved FEC timing fixes audible buffer underruns in UDP mode
271 - --log_color actually works
272 - new ls option: -d (print dates as seconds after the epoch)
273 - update to gengetopt 2.22.2
274 - support for RSA keys of size > 512 bits
275 - new option "mixer_channel" for para_fade
276
277 -----------------------------------------
278 0.3.4 (2009-05-07) "elliptic inheritance"
279 -----------------------------------------
280
281 The new udp sender, forward error correction, colored logs and various
282 other improvements. As the udp sender does not depend on any special
283 libraries, it is built unconditionally.
284
285 - The udp sender replaces the ortp sender. The new code uses forward
286 error correction to protect against packet losses. Many thanks to
287 Gerrit Renker for providing ipv6 support.
288 - The default port for udp streaming now defaults to 8000, like
289 for the http and the dccp senders/receivers.
290 - Loglevels are now specified as symbolic names, e.g.
291 "--loglevel info".
292 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
293 - para_server/para_audiod: Color support for log messages.
294 - new options for mp3dec: --ignore-crc, --bufsize
295 - new audiod option: --config-file.
296 - gengetopt cleanups.
297 - Improved help/man pages: The documentation of para_audiod,
298 para_recv, para_filter and para_write now also contains
299 all options of the available receivers/filters/writers. The
300 man page of para_fade contains a description of the different
301 modes of operation.
302 - More source code documentation.
303 - vss timing fixes.
304
305 --------------------------------------------
306 0.3.3 (2008-12-01) "axiomatic perspectivity"
307 --------------------------------------------
308
309 Internal code cleanups, bug fixes, improved tag handling and the new
310 amplification filter.
311
312 - para_server uses the generic scheduling code.
313 - overhaul of the virtual streaming system.
314 - mp3: id3 version 2 support via libid3tag (optional)
315 - ogg: vorbis comment support.
316 - aac meta info support.
317 - mp3 audio format handler cleanups.
318 - new filter: "amp" to amplify the amplitude of the audio stream
319 - new status item/database entry: amplification. It is
320 used by the amp filter to pre-amplify the audio stream.
321 - fix a close-without-open bug in para_write.
322 - fix a bug in com_init() which was introduced in 0.3.2.
323 - better error diagnostics for para_client.
324
325 -----------------------------------------
326 0.3.2 (2008-04-11) "probabilistic parity"
327 -----------------------------------------
328
329 The new para_afh executable, scheduling and documentation improvements.
330
331 - new ls option: -lc (list chunk table)
332 - new executable: para_afh, the stand-alone audio file handler tool
333 - afs commands can send output more than SHMMAX (32MB on Linux). This
334 also reduces the memory usage of commands that produce large amounts
335 of output.
336 - major scheduler and audiod cleanups.
337 - more detailed and much nicer man pages.
338
339 ---------------------------------------
340 0.3.1 (2008-02-23) "liquid interaction"
341 ---------------------------------------
342
343 A mix of cleanups, bug fixes, improvements, and some new features. No
344 significant changes to the new database (osl) code, which is generally
345 a good sign.
346
347 - Share some similar/duplicate code between the http and the
348 dccp sender.
349 - Generic access control lists for paraslash senders.
350 - dccp sender: Access control lists, connection limiting and support
351 for the allow,deny,on,off,help sender commands.
352 - The default dccp port changed from 5001 to 8000 (suggested by
353 Gerrit Renker).
354 - para_server starts even if not all public keys could be loaded.
355 - Audiod performance improvements.
356 - fix a bug in the "off" command of the http sender.
357 - fix some fd and memory leaks.
358 - Update to gengetopt-2.22.
359
360 -------------------------------------
361 0.3.0 (2008-01-12) "solar saturation"
362 -------------------------------------
363
364 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
365
366
367 Usually one might expect lots of new features AND a big increase in size
368 for a major release like this.
369
370 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
371 ever. The decrease in size is mostly due to the removal of some
372 graphical tools (which were only quick hacks anyway). But also the
373 fact that the mysql code is gone cuts down the size a bit.
374
375 Being independent of mysql comes at a cost: The fact that paraslash
376 now contains its own database (the object storage layer, osl) increases
377 the (stripped) binary size of para_server by ~50K on i386.
378
379 - no more restrictions on unique basenames.
380 - independent of mysql: The new self-contained object
381 storage layer (osl) replaces the mysql database.
382 - New executable para_fsck: Check integrity of osl tables.
383 - Lyrics support.
384 - Reliable audio file move/rename detection.
385 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
386 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
387 Solaris (sparc64).
388 - the new osl-based audio file selector (afs) replaces the random,
389 the playlist and the mysql selector of paraslash-0.2.x.
390 - IPv6 support (thanks to Gerrit Renker).
391 - paraslash-0.2.x streams are now called "moods". Writing
392 0.3.x-mood definitions should be both easier and more
393 powerful than writing 0.2.x-stream definitions.
394 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
395 been removed. The world is a better place without them. However,
396 para_gui is still there.
397 - afs tracks audio file selection also in playlist mode.
398 - few easy-to-use afs commands replace the many not-so-easy-to-use
399 mysql commands (and are available also in playlist mode).
400 - Improved error subsystem.
401 - The earth-shaking new logo.
402
403 -----------------------------------------
404 0.2.17 (2007-11-20) "isotropic threshold"
405 -----------------------------------------
406
407 Mainly bugfixes and cleanups in this version which marks the end of
408 the 0.2.x series if no serious bugs show up after the release.
409
410 - mysql_selector: fix a locking bug.
411 - universal chunk queueing.
412 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
413 to Gerrit Renker).
414 - be more carful wrt. signed vs. unsigned argument passing.
415 - cleanup error.h and fix some references to invalid error
416 codes.
417 - update to gengetopt-2.21.
418 - update to ortp-0.13.1.
419 - autoconf: extend checks for headers, library functions and
420 compiler characteristics.
421 - Fix streaming of large mp3 files.
422 - Fix an off-by-one bug in playlist handling.
423
424 --------------------------------------
425 0.2.16 (2007-04-05) "neural discharge"
426 --------------------------------------
427
428 The main change in this release is the major audio format handler
429 cleanup which removes some similar/duplicate code and makes it easier
430 to implement plugins for other audio formats. Of course, the usual mix
431 of other improvements/changes/bugfixes also made it into the release.
432
433 - simplified audio format handlers (most of the handling functions
434 were moved one layer up to the virtual streaming system).
435 - para_server uses mmap to read audio files
436 - repositioning of mp3 streams is much faster, in particular for
437 jumping near the end of large mp3 files.
438 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
439 and AFS_WRITE.
440 - fix a bug in para_filter that caused decoding of aac files
441 to start only after a few seconds.
442 - fix osx_writer hangs
443 - simplified dccp code (thanks to Gerrit Renker)
444 - the compress filter works also on big endian systems (ppc)
445
446 -----------------------------------------
447 0.2.15 (2007-02-16) "inductive resonance"
448 -----------------------------------------
449
450 Minor improvements, more documentation and a bunch of bug fixes.
451
452 - para_server: The server.users file is only read once on server
453 startup rather than for each connection
454 - mp3dec: Fix decoding of corrupt mp3 files
455 - afs (audio file sender) is now called vss (virtual streaming
456 system). Consequently, the permission flags specified in
457 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
458 become VSS_READ and VSS_WRITE respectively.
459 - para_audiod/para_filter: Fix a bug that caused the last chunk
460 of audio data not being written under certain circumstances
461 - audiod: compute the difference of server time and local time
462 correctly
463 - para_server/para_audiod: Fix some memory leaks
464 - documentation improvements
465 - configure.ac: fix checks for para_krell
466 - new man pages
467
468 -------------------------------------------
469 0.2.14 (2006-10-15) "transient singularity"
470 -------------------------------------------
471
472 The only major enhancement of this version is the osx writer which completes
473 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
474 until now for reasons beyond the scope of this changelog entry.
475
476 - new output plugin for Mac Os: the osx writer
477 - rename configure command line options from --enable-xxx-headers to
478 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
479 - configure: new command line options: --with-mad-headers,
480 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
481 - some robustness fixes
482 - dymamic audio format recognition for audiod
483 - para_server: new command line option: --autoplay_delay
484 - para_audiod: new command line option: --clock_diff_count
485
486 ---------------------------------------
487 0.2.13 (2006-07-14) "sonic convolution"
488 ---------------------------------------
489
490 A bunch of new features and core changes.
491
492 - the new paraslash scheduler, short and sweet.
493 - Support for m4a/mp4 files via the new aac audio format
494 handler/filter (requires libfaad).
495 - each writer has its own command line parser, just like
496 para_recv and para_filter.
497 - para_client and para_audioc use the error subsystem
498 - writers are integrated in para_audiod (currently linux-only)
499 - para_client is integrated in para_audiod
500 - random/playlist selector: improved info strings
501 - new audiod commands: tasks, kill
502 - update to libortp-0.10.1
503 - para_fade: wake time defaults to 8 hours from now
504 - update to autoconf-2.60
505
506
507 ------------------------------------------
508 0.2.12 (2006-05-12) "oriented abstraction"
509 ------------------------------------------
510
511 Many user-visible changes in this release and lots of new
512 features:
513
514
515 - the new optional dccp sender/receiver. It uses the datagram
516 congestion control protocol. You'll need a fairly new kernel
517 for this.
518 - paraslash works on Mac OS X (thanks to Gerd Becker)
519 - para_play renamed to para_write
520 - modular output plugin design (writers) for para_write
521 - new file_writer output plugin for para_write
522 - compress filter speed improvements
523 - update to libortp-0.9.1
524 - update to gengetopt-2.17rc
525 - para_client no longer depends on libreadline (as the
526 code for the interactive mode was removed).
527 - gcc-2-95 is no longer a supported compiler. It may still
528 work, but it gets no more testing.
529 - the tarball no longer contains the screenshot images which
530 reduces its size quite a bit.
531 - configure: new command line options: --enable-mysql-headers
532 and --enable-mysql-libs
533
534 ------------------------------------
535 0.2.11 (2006-03-11) "atomic duality"
536 ------------------------------------
537
538 Here it is, the first paraslash release developed with git. There
539 are fairly many user-visible changes in this release. As two out of
540 the three "database tools" of paraslash don't use a database at all,
541 they are now called "audio file selectors" instead.
542
543
544 - the cdt command (change database tool) becomes chs (change
545 selector)
546 - no more colon separators: The syntax of some options of
547 para_audiod and para_filter have changed. Use --help for
548 more info (and some examples).
549 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
550 - switch from cvs to git (should've done that earlier)
551 - the new ipc subsystem
552 - new audio file selector: playlist
553 - para_server: the dopey selector is now called "random",
554 and is the default selector. Use the --selector option to
555 choose another selector at startup, or the chs command to
556 change the selector at runtime.
557 - X86_64 fixes (thanks to Steffen Klassert)
558 - para_play fixes
559
560
561 --------------------------------------
562 0.2.10 (2006-02-17) "cyclic attractor"
563 --------------------------------------
564
565 Huge documentation update, a scrollable window for para_gui, ortp
566 improvements, and of course many small fixes not mentioned here.
567 The diffstat below is rather misleading as most insertions are due
568 to the new source documentation.
569
570 - autoconf cleanup
571 - para_server also uses the new error subsystem
572 - lots of new documentation (UTSL)
573 - gui improvements:
574 - keysyms for cursor keys and for next/previous page keys
575 - scrollable output window
576 - new internal commands: scroll up/down, page up/down
577 - fix color of command output.
578 - ortp: the --chunk_time and --header flags are no longer needed
579 for para_recv/para_audiod as this information is now encoded in
580 each rtp packet sent by para_server.
581
582
583 -------------------------------------------
584 0.2.9 (2006-01-24) "progressive turbulence"
585 -------------------------------------------
586
587 Internal audiod receivers/filters, the new error subsystem and
588 a lot of small improvements.
589
590 - para_recv and para_filter are integrated into the para_audiod
591 binary, i.e. audiod no longer spawns a new process for
592 each receiver/filter. As para_recv and para_filter might be
593 useful as standalone programs, they still get built (linked
594 against the same object files that are also used for audiod).
595 - further ortp timing improvements should reduce the CPU usage
596 of the ortp receiver.
597 - improved audio grabbing. The 'grab' command of para_audiod
598 has its own set of command line options. Read the output of
599 "para_audioc help grab" for more info.
600 - oggdec: configurable input prebuffer size.
601 - the new error subsystem gives better error diagnostics
602 and reduces code size.
603
604
605 -----------------------------------------
606 0.2.8 (2006-01-02) "dynamic accumulation"
607 -----------------------------------------
608
609 The new modular filter design and the para_play-hangs bugfix.
610
611 - new executable: para_filter. It combines para_mp3dec,
612 para_oggdec and para_compress. It also adds a further filter
613 type, wav, that just inserts a wave header at the desired point
614 of the filter chain. All 'piping' is done in-memory (i.e. no
615 read/write operations are used).
616 - para_play: fix a stupid bug that caused it to hang under
617 certain circumstances.
618
619
620 -------------------------------------------
621 0.2.7 (2006-12-27) "transparent invariance"
622 -------------------------------------------
623
624 Not many user-visible changes but a fair amount of internal improvements.
625
626
627 - The http sender buffers data if it can not be sent
628 out immediately (because the socket is not writable). This
629 should prevent para_server from shutting down the connection
630 too early on a loaded network.
631 - para_play also prebuffers data if it is told to start at a
632 future time by the --start_time option.
633 - The return of para_recv: It combines para_ortp_recv and
634 para_http_recv. Use the --receiver option to switch between
635 the two. para_recv builds without libortp, but contains
636 only the http receiver in this case.
637 - update to ortp 0.8.1. As this ortp release contains incompatible
638 changes, para_recv-0.2.7 won't link against older ortp libs.
639 - improved ortp timings.
640 - use of gcc-extensions that #define away for non-gcc and
641 gcc < 3.0.
642
643
644 -------------------------------------------
645 0.2.6 (2005-10-29) "recursive compensation"
646 -------------------------------------------
647
648 Transparent session encryption (uses openssl's Alleged RC4 cipher),
649 the internal find command and several other improvements and cleanups.
650
651 - Encrypt the session if encryption is requested by the client
652 (default for para_client 0.2.6). This is backwards
653 compatible, so older clients can still connect to para_server
654 0.2.6. Use the new client option --plain to request an
655 uncrypted session (off by default, must be set to on in
656 order to connect to para_server 0.2.x with 0 <= x <= 5).
657 - para_server uses an internal function to locate audio files
658 rather than calling find(1). The server option
659 --mysql_audio_file_dir replaces --mysql_find_cmd.
660 - documentation update
661 - man pages
662 - header file cleanup
663 - para_client code cleanup
664 - para_gui: faster display of output of display commands
665
666
667 ------------------------------------------
668 0.2.5 (2005-10-13) "aggressive resolution"
669 ------------------------------------------
670
671 This release adds internal senders, i.e. no more external programs are
672 spawned for sending out the audio data. There are two different senders
673 available: The http sender and the ortp sender (former para_send which
674 is no longer needed).
675
676 The new sender code has a plugin-like design so it can be easily
677 extended should there be be any future need for supporting another
678 network streaming protocol. All senders are completely independent of
679 each other. In particular, the http and the ortp sender can operate
680 in parallel.
681
682 - new server command: sender to control senders at runtime.
683 Read the output of "para_server -h" and "para_client help
684 sender" for more information.
685 - para_recv renamed to para_ortp_recv
686 - new executable: para_http_recv, a simple command line
687 http receiver.
688 - major afs/mp3/ogg code simplifications due to internal
689 senders.
690 - ogg timing improvements
691 - fix several minor memory leaks (found by valgrind)
692 - empty stream definitions work again
693 - com_ne(): ignore errors on remove
694 - audiod: fix segfault on server restart
695
696
697 ---------------------------------------
698 0.2.4 (2005-09-21) "toxic anticipation"
699 ---------------------------------------
700
701 Several small improvements, fixes and the new grab command.
702
703 - audiod:
704 - new command: "grab" to grab the output of the stream reader
705 or any filters. Read the output of "para_audioc help grab"
706 for more information.
707 - fix memory leak
708 - code cleanup
709 - audioc: new command line option: --bufsize to specify a
710 buffer size different from the default size 8192.
711 - improved error diagnostics for para_play.
712 - new configure option: --enable-ssldir so search for openssl in
713 non-standard places
714 - sdl_gui: Make it look nice again for 1024x768
715 - server: report total size of memory allocated with sbrk by malloc,
716 new command line option: --announce_time
717
718
719 -----------------------------------------
720 0.2.3 (2005-09-01) "hydrophilic movement"
721 -----------------------------------------
722
723 Two new executables and major feature enhancements.
724
725 - audiod filters: It is now possible to specify arbitrary many
726 (including none) filters for each supported audio
727 format. This can be used e.g. for normalizing volume,
728 transforming or grabbing the audio stream, or for using
729 visualizers. Read the output of "para_audiod -h" for the
730 syntax of the new --filter_cmd option.
731 - new executable: para_play, a tiny alsa player. It
732 can play wave files or raw pcm (16 bit little endian)
733 from stdin.
734 - new executable: para_compress, a dynamic range compressor
735 intended to keep audio output at a consistent volume. Derived
736 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
737 - audiod: New option: --stream_delay. This can be used in
738 a local network to syncronize the audio output of all
739 clients that play the same stream.
740
741
742 ------------------------------------------
743 0.2.2 (2005-08-19) "tangential excitation"
744 ------------------------------------------
745
746 Mostly internal changes in this release, but also some new commands
747 for the mysql database tool.
748
749 - cleanup exec.c, fix para_exec bug
750 - compile time loglevel (log messages below the given level
751 won't be compiled in, which reduces the size of the
752 resulting binaries)
753 - new log macros that shorten the size of the source code.
754 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
755 to send only zeros. With this workaround, para_audioc works
756 again.
757 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
758 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
759 (new entry), "snp" (set numplayed). Read the manual for more
760 information.
761
762
763 ---------------------------------------
764 0.2.1 (2005-08-15) "surreal experience"
765 ---------------------------------------
766
767 Here comes paraslash-0.2.1. It contains a couple of new features and,
768 surprise, only minor bug fixes.
769
770 - kill noisy mp3 debug message
771 - cleanup of the build system
772 - para_server and para_client directly use the crypto routines
773 of the openssl library rather than invoking the openssl command
774 line utitlity
775 - server/audiod: new option --user to switch to the given user
776 when invoked as root. Read the output of "para_server -h" for
777 more information.
778 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
779 status. Default: "para_audioc stat"
780 - sdl_gui: new option --pic_cmd to be used to download the picture.
781 Default: "para_client pic"
782 - audiod: 5 slots ought to be enough for everybody
783 - audiod: new status item: Uptime, kill hup command
784
785
786
787 ------------------------------------------
788 0.2.0 (2005-08-06) "distributed diffusion"
789 ------------------------------------------
790
791 After several month of increased development activity, paraslash-0.2.0
792 has arrived. It contains many new features and is much more
793 self-contained than the old 0.1.x series. Enjoy!
794
795
796 - para_server: fix hang on song change and crash on sighup.
797 Speed up mysql queries. The DIR_LIKE macro is gone.
798 - new executables: para_audiod, the local audio daemon that
799 starts playback (uses SCM_CREDENTIALS socket magic) and
800 para_audioc, the corresponding client.
801 - new executables: para_mp3dec/para_oggdec, two really teensy
802 decoders. para_mp3dec is based on libmad, para_oggdec requires
803 libvorbisfile.
804 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
805 they are now called para_send and para_recv respectively.
806 - documentation updates
807 - para_gui is themable. For now there is the default theme that
808 looks as before and the simple theme: blue and easy.
809 - gui: audio streaming is now handled by audiod. Time display shows
810 playback time rather than streaming time
811 - slider: update to libzmw-0.2.0
812 - para_krell: fix crash on server shutdown
813 - switch from gzip to bzip2
814
815
816 ----------------------------------------
817 0.1.7 (2005-04-18) "melting penetration"
818 ----------------------------------------
819
820 The main change in this release is clearly the oggvorbis rewrite,
821 but there are also lots of smaller changes. If you intend to use both
822 the mp3 and the ogg plugin, it is recommended to use software mixing,
823 e.g. the dmix plugin which is provided by ALSA.
824
825 - new executables: para_ovsend and para_ovrecv for sending/receiving
826 oggvorbis files via rtp. Requires the open rtp library. Get it at
827 http://www.linphone.org/ortp/
828 - rewrite of the ogg_vorbis core code
829 - configure detects libzmw and, if detected, includes
830 para_slider to the list of binaries to be built by make
831 - server stream writers read from their associated fifo rather
832 than from stdin
833 - slider: two new sliders, lastplayed and numplayed
834 - fix nasty double free bug which caused random segfaults in case of
835 mp3 files with invalid header information
836 - gui: new command line option: --stream_timeout=seconds to
837 deactivate a slot if it is idle for that many seconds (default=`5')
838 - diffstats
839
840
841 ---------------------------------------
842 0.1.6 (2005-03-05) "asymptotic balance"
843 ---------------------------------------
844
845 Only little user-visible changes in this release. Mainly bugfixes and
846 core code cleanup. This is probably the most stable version ever if you
847 stick to mp3...
848
849 - fix several memory leaks
850 - rename default name of mysql database from "music" to "paraslash".
851 Use para_server's --mysql_database option if you do not want to
852 rename your old database.
853 - rework ogg vorbis code
854 - make update command work on mysql servers with LOCAL_INFILE
855 disabled
856 - gui: improved stream I/O (slots)
857 - simplified audio format API
858 - para_pob_ogg is gone
859
860 ------------------------------------
861 0.1.5 (2004-12-31) "opaque eternity"
862 ------------------------------------
863
864 Let's slide gently into the new year.
865
866 - new: para_slider (not built automatically, type "make
867 para_slider" to build). A toy for those who always felt that
868 creating stream definitions is difficult. See screenshots,
869 README and FEATURES for more info.
870 - improved signal handling. Fixes server segfault on SIGHUP
871 for linux kernels newer than Aug 24 2004 and makes para_gui
872 race-free.
873 - reload database tool on SIGHUP
874 - improved help message for sl
875 - do not log "broken pipe" messages as errors. They are
876 perfectly ok.
877 - fix wrong error message on permission errors
878
879 -----------------------------------------
880 0.1.4 (2004-12-19) "tunneling transition"
881 -----------------------------------------
882
883 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
884 Hopefully, most of them got wiped out with this release. Some
885 enhancements went also in.
886
887 - improved error diagnostics for all commands
888 - stradd/picadd: overwrite previous contents if entry already
889 exists, rather than returning errors
890 - stradd: use current stream if invoked without args
891 - faster (and hopefully more stable) ogg-vorbis handling
892 - para_krell: reap children to avoid zombie-flooding in case
893 no server is running
894 - si: report also server pid
895 - server: don't busy-loop if dbtool reports only invalid files.
896 - gui: CTRL+C works again, fix stream_read command line option
897 - fix pic_add, hist
898 - fix mysql dbtool startup in case no database exists
899 - many small fixes and cleanups
900
901 ---------------------------------------
902 0.1.3: (2004-12-10) "vanishing inertia"
903 ---------------------------------------
904
905 Starting from this release, the database tools are integrated in the
906 server binary. This decreases server startup time, reduces code size
907 and speeds up database commands. However, the layout of the underlying
908 mysql database changed only slightly and 0.1.3 should be backwards
909 compatible in that respect.
910
911 Visible changes:
912
913 - If mysql is not detected at compile time, or fails to init
914 at runtime, fall back to the dopey database tool which should
915 always work.
916 - para_dbtool and dbtool.conf are gone. All mysql specific
917 options are read from server.conf and are prefixed by 'mysql_'.
918 - new command: cdt (change database tool)
919 - new command line option: dbtool (choose startup database tool)
920 - The name of current stream is now stored in the database,
921 so paraslash remembers its current stream when restarted.
922 - new command: csp (change stream and play)
923 - para_gui also reports current database tool and server uptime
924
925
926 -------------------------------------------
927 0.1.2: (2004-11-28) "spherical fluctuation"
928 -------------------------------------------
929
930 Point release before the big dbtool changes go in.
931
932 - dbtool: rename ca to cam (copy all meta data). It now also
933 copies numplayed and lastplayed time as well as the picture
934 id.
935 - fix endless-loop-bug caused by mp3 files with invalid header
936
937 -----------------------------------------
938 0.1.1: (2004-11-05) "floating atmosphere"
939 -----------------------------------------
940
941 - gkrellm plugin
942 - new dbtool command: mbox. Browse your sound-file collection
943 with your favorite mail reader.
944 - several small fixes
945
946 -------------------------------------
947 0.1.0: (2204-10-22) "rotating cortex"
948 -------------------------------------
949
950 - fix logging bug for loglevel > VERBOSE
951 - fix skip command
952 - correct timings for vbr mp3s
953 - modular audio format support
954 - ogg-vorbis support (experimental)
955 - new server option: autoplay
956
957 -----------------------------------------
958 0.0.99: (2004-07-25) "harmonic deviation"
959 -----------------------------------------
960
961 - rename projectname from icc to paraslash (play, archive, rate
962 and stream large audio sets happily)
963 - paraslash is no longer restricted to one particular audio
964 streaming software
965 - new dbtool commands (stradd, strq, strdel) for easy stream
966 managment w/o configuration file. That obsoletes stream_defs
967 file/config option for dbtool.
968 - picadd accepts jpeg data from stdin
969 - new server commands: ps (select previous stream), sc (song change)
970 - new default pictures for sdl_gui
971 - gui: new key_map option for binding commands and internal
972 functions to arbitrary keys, nice help screen, rip out
973 soundcard/linux specific stuff, avoid noise artefacts while jumping,
974 show silly logo on startup
975 - new executables: para_fade for fading volume, para_dbadm for
976 manipulating attributes
977 - cdb adds _all_ tables to mysql database
978 - revised and beautified documentation
979 - sample dbtool rewritten in C
980 - autoconf
981
982 ---------------------------------------------
983 0.0.98: (2003-12-26) "incremental smoothness"
984 ---------------------------------------------
985
986 - kick icecast in favour of poc. That removes some races and reduces
987 core code considerably.
988 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
989 give finer info on afs' status.
990 - gui can start decoder (see config options). Further new gui
991 commands: refresh (^L), jmp (F1-F10)
992 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
993 terminates gui. This fixes dead instances consuming memory
994 continuously.
995 - new dbtool command: verb for sending verbatim sql queries.
996 - fix pid_list races (by removing pid_list)
997 - codename funnies
998
999 --------------------
1000 0.0.97: (2003-10-26)
1001 --------------------
1002
1003 - installation prefix now defaults to /usr/local
1004 - new commands for gui: snozze, sleep and reread config
1005 - config file for gui and sdl_gui
1006 - fix problems with filenames containing funny characters
1007 (reported by Thomas Forell)
1008 - improved signal handling for gui, now it rereads conf on SIGHUP
1009 - new dbtool command: cdb (create database)
1010 - switch from argtable to gengetopt
1011 - major code cleanup and speed improvements
1012 - fix several potential buffer overflows

1021 - Major feature enhancements for icc_gui including dynamic text
1022 placement and the top/bottom window design
1023 - vrfy/clean now also checks for NULL values in attributes as
1024 well as for invalid picture pointers
1025 - fix long outstanding case sensitivity bug
1026 - many small fixes and cleanups
1027
1028 -------------------
1029 0.0.95 (2003-06-29)
1030 -------------------
1031
1032 - sdl gui runs much faster
1033 - new dbtool command: ca (copy attributes)
1034 - count and display number of times the song has been played
1035 - new feature: scoring
1036 - command line options for sdl_gui
1037 - simpler syntax of streams file
1038 - decrease network traffic of stat
1039 - fix zombie bug
1040 - many small fixes and cleanups
1041
1042 -------------------
1043 0.0.94 (2003-05-04)
1044 -------------------
1045
1046 - new server command: ns (next stream)
1047 - new icc_gui command: c (change stream)
1048 - internal mp3info
1049 - stat shows also id3 tag info
1050 - new sdl based gui
1051 - log flodding bug fixed
1052 - many small fixes and cleanups
1053
1054 -------------------
1055 0.0.93 (2003-03-28)
1056 -------------------
1057
1058 - colors for icc_gui
1059 - icc_gui sets volume directly (linux only)
1060 - proper locking that fixes some races
1061 - fix security bug that caused commands to be executed even
1062 with unsufficient permissions
1063 - new command: hup to make all servers reread their configuration file
1064 - icecast meta data streaming
1065 - many small fixes and cleanups
