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

1022 - count and display number of times the song has been played
1023 - new feature: scoring
1024 - command line options for sdl_gui
1025 - simpler syntax of streams file
1026 - decrease network traffic of stat
1027 - fix zombie bug
1028 - many small fixes and cleanups
1029

1041
1042 -------------------
1043 0.0.93 (2003-03-28)
1044 -------------------
1045
1046 - colors for icc_gui
1047 - icc_gui sets volume directly (linux only)
