1 ------------------------------------------
2 0.?.? (to be announced) "spectral gravity"
3 ------------------------------------------
4
5 - UTF8 support for para_gui and the mp3 audio format handler.
6 - Scheduler improvements and fixes.
7 - The obsolete gettimeofday() function has been replaced
8 by clock_gettime() on systems which support it.
9 - Speed and usability improvements for para_gui.
10 - para_client now restores the fd flags of stdin and stdout
11 on shutdown.
12 - Performance improvements for the compress filter.
13
14 -----------------------------------------
15 0.4.12 (2012-12-20) "volatile relativity"
16 -----------------------------------------
17 The new command line player, the resample filter, ALSA support for
18 para_fade, and the improved build system are the highlights of this
19 release which probably marks the end of the 0.4.x series.
20
21 - The afh receiver and the para_play executable.
22 - The resample filter: A sample rate converter based on
23 libsamplerate.
24 - The "versions" directory has been removed from the master
25 branch. The tarballs of the old releases are now available
26 in the new "releases" branch.
27 - Overhaul of the build system: All generated files are now
28 written to the "build" directory.
29 - The modular mixer API and the alsa mixer.
30 - Minor fixes for the osx writer.
31
32 --------------------------------------
33 0.4.11 (2012-07-20) "mutual diversity"
34 --------------------------------------
35
36 The major feature in this release is the new sideband API for
37 client-server communication. This API will be used exclusively starting
38 with 0.5.0, which breaks backward compatibility but allows to get rid
39 of quite some compatibility code. Other noteworthy changes include
40 decoder latency improvements and a long-standing bug fix for the
41 ALSA writer.
42
43 - Sideband connections: If both para_server and para_client
44 support this feature, data is sent as a multiplexed stream.
45 - The --no_default_filters option of para_filter has been
46 removed.
47 - Several fixes and latency improvements to various decoders.
48 - The ALSA writer now limits the prebuffer time to 500ms.
49 - Documentation improvements.
50 - Overhaul of the command_util.sh script.
51 - Fixes for some minor problems found by the clang analyzer.
52 - Compiles (almost) without warnings on gcc-3.
53 - Robustness improvements of the buffer tree code.
54
55 ------------------------------------------
56 0.4.10 (2012-03-30) "heterogeneous vacuum"
57 ------------------------------------------
58
59 Nothing earth-shaking in this release, but quite a few usability
60 improvements and the usual mix of cleanups and fixes.
61
62 - The --no_default_filters option of para_filter has been
63 deprecated. It still works but has no effect and will be
64 removed in the next version.
65 - para_gui now prints also the stderr output of the executing
66 command in the bottom window.
67 - Cleanup and consolidation of the various wrappers for
68 write(), writev(), send() and friends.
69 - The obscure error messages on mmap() failures have been
70 replaced by meaningful messages. This affects mainly
71 para_afh.
72 - para_audioc: Cleanups and memory leak fixes.
73 - Test 0004-server no longer fails if para_server is not
74 being built.
75 - New configure options: --with-id3tag-{headers,libs}.
76
77 -------------------------------------
78 0.4.9 (2011-12-06) "hybrid causality"
79 -------------------------------------
80
81 Support for another audio format, interactive mode for para_client
82 and para_audiod and many small improvements/fixes all over the place.
83
84 - Support for flac, the free lossless audio codec.
85 - Fix for an endless loop in the mp3 decoder for certain
86 (corrupt) mp3 files.
87 - When executed without specifying a command, para_client
88 and para_audioc start an interactive shell (requires
89 libreadline being installed). The interactive mode offers
90 full tab completion and command line history.
91 - autogen.sh now detects a distcc setup and adjusts the
92 parameter for the -j option of make accordingly.
93 - Shared memory areas are no longer restricted to 64K. We now
94 detect the maximal size of a shared memory area at runtime.
95 - cleanup of the internal uptime API.
96 - para_server prefaults the mmapped audio file to avoid
97 delays on slow media.
98 - A new test for the test-suite that exercises the
99 communication between para_server and para_audiod.
100 - The alsa writer eats up less CPU cycles when configured to
101 use the DMIX plugin.
102 - Simplified and unified receiver code.
103 - Makefile cleanups.
104 - Commands which print a list of matching audio files now
105 emit a meaningful error message if no audio file matched the
106 given pattern(s).
107
108 --------------------------------------
109 0.4.8 (2011-08-19) "nested assignment"
110 --------------------------------------
111
112 Gcrypt support, the overhauled osx writer and regex format specifiers
113 are the highlights of this release.
114
115 - support for libgcrypt as a drop-in replacement for openssl.
116 Run configure --enable-cryptolib=gcrypt to link against
117 libgcrypt. The two crypto implementations are compatible to
118 each other, i.e. a para_client executable linked against
119 gcrypt can connect to para_server linked against libssl
120 and vice versa.
121 - Rewrite of the osx writer (output plugin for Mac OS).
122 - audiod: The format specifier for receivers, filters and
123 writers is now treated as a regular expression. This allows
124 to replace 5 lines in the config file (one for each audio
125 format) by one single line. See the manual for details.
126 - The *.cmdline.[ch] files are no longer contained in the released
127 tarballs. This reduces the size of the tarballs but requires
128 gengetopt to build the tarball.
129 - Compiles cleanly also with llvm/clang.
130 - Corrupt mp3 files are handled more gracefully.
131 - The alsa writer uses poll fds instead of computing timeouts.
132 - Cleanup of the generic writer API.
133 - sched: Optimized zero timeouts.
134 - vss timeout cleanups.
135 - oggdec fixes and improvements.
136
137 --------------------------------------
138 0.4.7 (2011-06-01) "infinite rollback"
139 --------------------------------------
140
141 The new ao writer, support for ssh RSA keys and a couple of other
142 enhancements.
143
144 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
145 platforms through the libao audio library.
146 - Support for RSA keys generated with ssh-keygen.
147 - configure: improved options for ogg/vorbis/speex.
148 - The git version reported by --version always matches HEAD.
149 - The autogen script detects the number of processors and
150 runs a parallel make if possible.
151 - Major cleanup of the crypto API.
152 - Documentation updates.
153
154 ------------------------------------------
155 0.4.6 (2011-03-31) "deterministic entropy"
156 ------------------------------------------
157
158 Lots of ogg/vorbis improvements, the new test suite, enhancements
159 for para_gui and a fair amount of other bug fixes.
160
161 - For DCCP/OGG streams the audio file header is only sent once
162 at the beginning of the stream rather than periodically
163 every five seconds. This reduces network traffic and the
164 FEC group size.
165 - The vorbis comment header is replaced by an empty dummy header
166 before the header is sent over the network. This also results in
167 less network traffic and smaller FEC groups.
168 - The new "test" make target allows to perform some sanity checks prior
169 to installing the package.
170 - ogg timing fixes and performance improvements
171 - Scheduler improvements
172 - Proper exit codes for para_write
173 - para_gui: New option --theme to select a startup theme. Several
174 other improvements and fixes.
175 - aacdec error message cleanups
176 - simplified color error handling
177
178 --------------------------------------------
179 0.4.5 (2010-12-17) "symmetric randomization"
180 --------------------------------------------
181
182 Bug fixes, internal cleanups and variable-sized FEC slices.
183
184 - Contains a fix for an invalid-free-bug in the ogg audio format
185 handler code.
186 - Switching off the DCCP sender works again.
187 - para_audiod handles crashes of para_server more robustly.
188 - Internal scheduler and writer cleanups.
189 - Reduced latency due to variable-sized FEC slices.
190 - Improved documentation and error diagnostics.
191 - The build of para_server is now optional, allowing the build
192 to succeed in case libosl is not installed.
193
194 ------------------------------------------
195 0.4.4 (2010-08-06) "persistent regularity"
196 ------------------------------------------
197
198 Support for yet another audio format, para_write improvements and
199 bug fixes.
200
201 - Support for the speex codec.
202 - Support for sample formats other than 16 bit little endian.
203 - error2.h is now created by a perl script which speeds up configure
204 considerably.
205 - Fix a bug in the aac decoder which could lead to segfaults in
206 para_filter/para_audiod.
207 - Fixes for autoconf-2.66.
208
209 ----------------------------------------
210 0.4.3 (2010-07-05) "imaginary radiation"
211 ----------------------------------------
212
213 Many improvements for the DCCP and the UDP transport, the new user
214 manual and the usual mix of bug fixes and internal improvements.
215
216 - FEC support for the DCCP sender (Gerrit Renker). The new
217 --dccp_max_slice_size, --dccp_data_slices_per_group and
218 --dccp_slices_per_group options can be used to set the FEC
219 parameters for the DCCP transport.
220 - DNS lookups for UDP targets (Gerrit Renker).
221 - The new user manual replaces the README, README.afs, REQUIREMENTS
222 and INSTALL documents.
223 - Fix an end-of-file detection bug in the oggdec filter.
224 - The new nonblock API.
225 - Both options of the oggdec filter have been removed.
226 - New debug mode for the internal scheduler.
227
228 ------------------------------------------
229 0.4.2 (2010-04-23) "associative expansion"
230 ------------------------------------------
231
232 It's been some time since the last release, but finally here is
233 paraslash-0.4.2. The bulk of the changes comes from the new buffer
234 tree API, but there are changes all over the tree. Mainly performance
235 and usability improvements, but also quite some bug fixes.
236
237 - The new buffer tree API.
238 - DCCP: Support for CCID negotiation (Gerrit Renker).
239 - UDP robustness fixes.
240 - The --bufsize option for mp3dec is gone as it no longer makes sense
241 for the new buffer tree API.
242 - Fix audible buffer underruns for wma streams.
243 - The alsa writer no longer prints meaningless underrun durations.
244 - audiod: Defaults work also for udp streams. If no filter is
245 given for an audio format that is received via upd, fecdec is
246 automatically added as the first filter (along with the decoder).
247
248 ---------------------------------------
249 0.4.1 (2009-12-22) "concurrent horizon"
250 ---------------------------------------
251
252 Support for another audio format, minor feature enhancements and lots of bug
253 fixes. All fixes that have been accumulated in the maint branch (in particular
254 those mentionened in the 0.3.6 release notes) appear in this release as well.
255
256 - wma support.
257 - new afh option: --human to activate human-readable output.
258 - new server/audiod option: --log-timing to print timing information.
259 - build system improvements.
260 - source code documentation updates.
261
262 -------------------------------------
263 0.3.6 (2009-12-07) "cubic continuity"
264 -------------------------------------
265
266 Quite a few bugs have been found and fixed since 0.3.5, so here's
267 another 0.3.x release. No new features.
268
269 - Always check return value of malloc().
270 - ogg vorbis/FEC: Do not write garbage after the audio file header.
271 - exit if root privileges could not be dropped.
272 - FEC: Fix computation of extra slices.
273 - oss: Fix check for empty input buffer.
274 - Avoid buffer underruns due to filter chain output buffer constraints.
275 - server: Fix assignment of afs_pid.
276 - Don't panic if the afs database contains unknown audio formats.
277 - http/dccp: Do not send the audio file header twice.
278 - FEC: Timing improvements.
279
280 ----------------------------------------------
281 0.4.0 (2009-11-10) "simultaneous independence"
282 ----------------------------------------------
283
284 Two significant changes which require the new version number: The
285 improved authentication dialog and the fact that the database code
286 has been moved to a library, libosl. To use the new version, you have
287 to generate new RSA keys, see INSTALL for details. A shell script is
288 provided for conversion of the 0.3 database to the new 0.4 format.
289
290 - stronger crypto for client authentication
291 - the database code has been moved to a library
292 - improved status item handling
293 - cleanup of the build system
294 - The "-V" option now also prints the git version
295 - the new parser-friendly listing mode for the ls and stat commands
296 - mandatory rc4 encryption
297 - major audio format handler cleanups
298 - (id3,...) tags are no longer stored as a combined string in the database
299 - new mood methods: artist_matches, title_matches, comment_matches,
300 album_matches, year_maches, year.
301
302 --------------------------------------------
303 0.3.5 (2009-09-21) "symplectic separability"
304 --------------------------------------------
305
306 Full client support for *BSD Unixes, complete re-write of the ogg
307 vorbis audio format handler, various improvements all over the place
308 and the usual mix of bugfixes. This release marks the end of the 0.3
309 series if no serious problems show up.
310
311 - the new oss writer (supported on *BSD and Linux)
312 - rewrite of the ogg vorbis audio format handler. It's
313 recommended to replace the chunk tables of existing ogg
314 vorbis files in the afs database by re-adding these files
315 with "add -f".
316 - support for netmask subsets (Gerrit Renker)
317 - the new prebuffer filter
318 - improved signal handling
319 - variable fec output buffer size
320 - improved FEC timing fixes audible buffer underruns in UDP mode
321 - --log_color actually works
322 - new ls option: -d (print dates as seconds after the epoch)
323 - update to gengetopt 2.22.2
324 - support for RSA keys of size > 512 bits
325 - new option "mixer_channel" for para_fade
326
327 -----------------------------------------
328 0.3.4 (2009-05-07) "elliptic inheritance"
329 -----------------------------------------
330
331 The new udp sender, forward error correction, colored logs and various
332 other improvements. As the udp sender does not depend on any special
333 libraries, it is built unconditionally.
334
335 - The udp sender replaces the ortp sender. The new code uses forward
336 error correction to protect against packet losses. Many thanks to
337 Gerrit Renker for providing ipv6 support.
338 - The default port for udp streaming now defaults to 8000, like
339 for the http and the dccp senders/receivers.
340 - Loglevels are now specified as symbolic names, e.g.
341 "--loglevel info".
342 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
343 - para_server/para_audiod: Color support for log messages.
344 - new options for mp3dec: --ignore-crc, --bufsize
345 - new audiod option: --config-file.
346 - gengetopt cleanups.
347 - Improved help/man pages: The documentation of para_audiod,
348 para_recv, para_filter and para_write now also contains
349 all options of the available receivers/filters/writers. The
350 man page of para_fade contains a description of the different
351 modes of operation.
352 - More source code documentation.
353 - vss timing fixes.
354
355 --------------------------------------------
356 0.3.3 (2008-12-01) "axiomatic perspectivity"
357 --------------------------------------------
358
359 Internal code cleanups, bug fixes, improved tag handling and the new
360 amplification filter.
361
362 - para_server uses the generic scheduling code.
363 - overhaul of the virtual streaming system.
364 - mp3: id3 version 2 support via libid3tag (optional)
365 - ogg: vorbis comment support.
366 - aac meta info support.
367 - mp3 audio format handler cleanups.
368 - new filter: "amp" to amplify the amplitude of the audio stream
369 - new status item/database entry: amplification. It is
370 used by the amp filter to pre-amplify the audio stream.
371 - fix a close-without-open bug in para_write.
372 - fix a bug in com_init() which was introduced in 0.3.2.
373 - better error diagnostics for para_client.
374
375 -----------------------------------------
376 0.3.2 (2008-04-11) "probabilistic parity"
377 -----------------------------------------
378
379 The new para_afh executable, scheduling and documentation improvements.
380
381 - new ls option: -lc (list chunk table)
382 - new executable: para_afh, the stand-alone audio file handler tool
383 - afs commands can send output more than SHMMAX (32MB on Linux). This
384 also reduces the memory usage of commands that produce large amounts
385 of output.
386 - major scheduler and audiod cleanups.
387 - more detailed and much nicer man pages.
388
389 ---------------------------------------
390 0.3.1 (2008-02-23) "liquid interaction"
391 ---------------------------------------
392
393 A mix of cleanups, bug fixes, improvements, and some new features. No
394 significant changes to the new database (osl) code, which is generally
395 a good sign.
396
397 - Share some similar/duplicate code between the http and the
398 dccp sender.
399 - Generic access control lists for paraslash senders.
400 - dccp sender: Access control lists, connection limiting and support
401 for the allow,deny,on,off,help sender commands.
402 - The default dccp port changed from 5001 to 8000 (suggested by
403 Gerrit Renker).
404 - para_server starts even if not all public keys could be loaded.
405 - Audiod performance improvements.
406 - fix a bug in the "off" command of the http sender.
407 - fix some fd and memory leaks.
408 - Update to gengetopt-2.22.
409
410 -------------------------------------
411 0.3.0 (2008-01-12) "solar saturation"
412 -------------------------------------
413
414 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
415
416
417 Usually one might expect lots of new features AND a big increase in size
418 for a major release like this.
419
420 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
421 ever. The decrease in size is mostly due to the removal of some
422 graphical tools (which were only quick hacks anyway). But also the
423 fact that the mysql code is gone cuts down the size a bit.
424
425 Being independent of mysql comes at a cost: The fact that paraslash
426 now contains its own database (the object storage layer, osl) increases
427 the (stripped) binary size of para_server by ~50K on i386.
428
429 - no more restrictions on unique basenames.
430 - independent of mysql: The new self-contained object
431 storage layer (osl) replaces the mysql database.
432 - New executable para_fsck: Check integrity of osl tables.
433 - Lyrics support.
434 - Reliable audio file move/rename detection.
435 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
436 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
437 Solaris (sparc64).
438 - the new osl-based audio file selector (afs) replaces the random,
439 the playlist and the mysql selector of paraslash-0.2.x.
440 - IPv6 support (thanks to Gerrit Renker).
441 - paraslash-0.2.x streams are now called "moods". Writing
442 0.3.x-mood definitions should be both easier and more
443 powerful than writing 0.2.x-stream definitions.
444 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
445 been removed. The world is a better place without them. However,
446 para_gui is still there.
447 - afs tracks audio file selection also in playlist mode.
448 - few easy-to-use afs commands replace the many not-so-easy-to-use
449 mysql commands (and are available also in playlist mode).
450 - Improved error subsystem.
451 - The earth-shaking new logo.
452
453 -----------------------------------------
454 0.2.17 (2007-11-20) "isotropic threshold"
455 -----------------------------------------
456
457 Mainly bugfixes and cleanups in this version which marks the end of
458 the 0.2.x series if no serious bugs show up after the release.
459
460 - mysql_selector: fix a locking bug.
461 - universal chunk queueing.
462 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
463 to Gerrit Renker).
464 - be more carful wrt. signed vs. unsigned argument passing.
465 - cleanup error.h and fix some references to invalid error
466 codes.
467 - update to gengetopt-2.21.
468 - update to ortp-0.13.1.
469 - autoconf: extend checks for headers, library functions and
470 compiler characteristics.
471 - Fix streaming of large mp3 files.
472 - Fix an off-by-one bug in playlist handling.
473
474 --------------------------------------
475 0.2.16 (2007-04-05) "neural discharge"
476 --------------------------------------
477
478 The main change in this release is the major audio format handler
479 cleanup which removes some similar/duplicate code and makes it easier
480 to implement plugins for other audio formats. Of course, the usual mix
481 of other improvements/changes/bugfixes also made it into the release.
482
483 - simplified audio format handlers (most of the handling functions
484 were moved one layer up to the virtual streaming system).
485 - para_server uses mmap to read audio files
486 - repositioning of mp3 streams is much faster, in particular for
487 jumping near the end of large mp3 files.
488 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
489 and AFS_WRITE.
490 - fix a bug in para_filter that caused decoding of aac files
491 to start only after a few seconds.
492 - fix osx_writer hangs
493 - simplified dccp code (thanks to Gerrit Renker)
494 - the compress filter works also on big endian systems (ppc)
495
496 -----------------------------------------
497 0.2.15 (2007-02-16) "inductive resonance"
498 -----------------------------------------
499
500 Minor improvements, more documentation and a bunch of bug fixes.
501
502 - para_server: The server.users file is only read once on server
503 startup rather than for each connection
504 - mp3dec: Fix decoding of corrupt mp3 files
505 - afs (audio file sender) is now called vss (virtual streaming
506 system). Consequently, the permission flags specified in
507 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
508 become VSS_READ and VSS_WRITE respectively.
509 - para_audiod/para_filter: Fix a bug that caused the last chunk
510 of audio data not being written under certain circumstances
511 - audiod: compute the difference of server time and local time
512 correctly
513 - para_server/para_audiod: Fix some memory leaks
514 - documentation improvements
515 - configure.ac: fix checks for para_krell
516 - new man pages
517
518 -------------------------------------------
519 0.2.14 (2006-10-15) "transient singularity"
520 -------------------------------------------
521
522 The only major enhancement of this version is the osx writer which completes
523 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
524 until now for reasons beyond the scope of this changelog entry.
525
526 - new output plugin for Mac Os: the osx writer
527 - rename configure command line options from --enable-xxx-headers to
528 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
529 - configure: new command line options: --with-mad-headers,
530 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
531 - some robustness fixes
532 - dymamic audio format recognition for audiod
533 - para_server: new command line option: --autoplay_delay
534 - para_audiod: new command line option: --clock_diff_count
535
536 ---------------------------------------
537 0.2.13 (2006-07-14) "sonic convolution"
538 ---------------------------------------
539
540 A bunch of new features and core changes.
541
542 - the new paraslash scheduler, short and sweet.
543 - Support for m4a/mp4 files via the new aac audio format
544 handler/filter (requires libfaad).
545 - each writer has its own command line parser, just like
546 para_recv and para_filter.
547 - para_client and para_audioc use the error subsystem
548 - writers are integrated in para_audiod (currently linux-only)
549 - para_client is integrated in para_audiod
550 - random/playlist selector: improved info strings
551 - new audiod commands: tasks, kill
552 - update to libortp-0.10.1
553 - para_fade: wake time defaults to 8 hours from now
554 - update to autoconf-2.60
555
556 ------------------------------------------
557 0.2.12 (2006-05-12) "oriented abstraction"
558 ------------------------------------------
559
560 Many user-visible changes in this release and lots of new
561 features:
562
563
564 - the new optional dccp sender/receiver. It uses the datagram
565 congestion control protocol. You'll need a fairly new kernel
566 for this.
567 - paraslash works on Mac OS X (thanks to Gerd Becker)
568 - para_play renamed to para_write
569 - modular output plugin design (writers) for para_write
570 - new file_writer output plugin for para_write
571 - compress filter speed improvements
572 - update to libortp-0.9.1
573 - update to gengetopt-2.17rc
574 - para_client no longer depends on libreadline (as the
575 code for the interactive mode was removed).
576 - gcc-2-95 is no longer a supported compiler. It may still
577 work, but it gets no more testing.
578 - the tarball no longer contains the screenshot images which
579 reduces its size quite a bit.
580 - configure: new command line options: --enable-mysql-headers
581 and --enable-mysql-libs
582
583 ------------------------------------
584 0.2.11 (2006-03-11) "atomic duality"
585 ------------------------------------
586
587 Here it is, the first paraslash release developed with git. There
588 are fairly many user-visible changes in this release. As two out of
589 the three "database tools" of paraslash don't use a database at all,
590 they are now called "audio file selectors" instead.
591
592
593 - the cdt command (change database tool) becomes chs (change
594 selector)
595 - no more colon separators: The syntax of some options of
596 para_audiod and para_filter have changed. Use --help for
597 more info (and some examples).
598 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
599 - switch from cvs to git (should've done that earlier)
600 - the new ipc subsystem
601 - new audio file selector: playlist
602 - para_server: the dopey selector is now called "random",
603 and is the default selector. Use the --selector option to
604 choose another selector at startup, or the chs command to
605 change the selector at runtime.
606 - X86_64 fixes (thanks to Steffen Klassert)
607 - para_play fixes
608
609 --------------------------------------
610 0.2.10 (2006-02-17) "cyclic attractor"
611 --------------------------------------
612
613 Huge documentation update, a scrollable window for para_gui, ortp
614 improvements, and of course many small fixes not mentioned here.
615 The diffstat below is rather misleading as most insertions are due
616 to the new source documentation.
617
618 - autoconf cleanup
619 - para_server also uses the new error subsystem
620 - lots of new documentation (UTSL)
621 - gui improvements:
622 - keysyms for cursor keys and for next/previous page keys
623 - scrollable output window
624 - new internal commands: scroll up/down, page up/down
625 - fix color of command output.
626 - ortp: the --chunk_time and --header flags are no longer needed
627 for para_recv/para_audiod as this information is now encoded in
628 each rtp packet sent by para_server.
629
630 -------------------------------------------
631 0.2.9 (2006-01-24) "progressive turbulence"
632 -------------------------------------------
633
634 Internal audiod receivers/filters, the new error subsystem and
635 a lot of small improvements.
636
637 - para_recv and para_filter are integrated into the para_audiod
638 binary, i.e. audiod no longer spawns a new process for
639 each receiver/filter. As para_recv and para_filter might be
640 useful as standalone programs, they still get built (linked
641 against the same object files that are also used for audiod).
642 - further ortp timing improvements should reduce the CPU usage
643 of the ortp receiver.
644 - improved audio grabbing. The 'grab' command of para_audiod
645 has its own set of command line options. Read the output of
646 "para_audioc help grab" for more info.
647 - oggdec: configurable input prebuffer size.
648 - the new error subsystem gives better error diagnostics
649 and reduces code size.
650
651 -----------------------------------------
652 0.2.8 (2006-01-02) "dynamic accumulation"
653 -----------------------------------------
654
655 The new modular filter design and the para_play-hangs bugfix.
656
657 - new executable: para_filter. It combines para_mp3dec,
658 para_oggdec and para_compress. It also adds a further filter
659 type, wav, that just inserts a wave header at the desired point
660 of the filter chain. All 'piping' is done in-memory (i.e. no
661 read/write operations are used).
662 - para_play: fix a stupid bug that caused it to hang under
663 certain circumstances.
664
665 -------------------------------------------
666 0.2.7 (2006-12-27) "transparent invariance"
667 -------------------------------------------
668
669 Not many user-visible changes but a fair amount of internal improvements.
670
671
672 - The http sender buffers data if it can not be sent
673 out immediately (because the socket is not writable). This
674 should prevent para_server from shutting down the connection
675 too early on a loaded network.
676 - para_play also prebuffers data if it is told to start at a
677 future time by the --start_time option.
678 - The return of para_recv: It combines para_ortp_recv and
679 para_http_recv. Use the --receiver option to switch between
680 the two. para_recv builds without libortp, but contains
681 only the http receiver in this case.
682 - update to ortp 0.8.1. As this ortp release contains incompatible
683 changes, para_recv-0.2.7 won't link against older ortp libs.
684 - improved ortp timings.
685 - use of gcc-extensions that #define away for non-gcc and
686 gcc < 3.0.
687
688 -------------------------------------------
689 0.2.6 (2005-10-29) "recursive compensation"
690 -------------------------------------------
691
692 Transparent session encryption (uses openssl's Alleged RC4 cipher),
693 the internal find command and several other improvements and cleanups.
694
695 - Encrypt the session if encryption is requested by the client
696 (default for para_client 0.2.6). This is backwards
697 compatible, so older clients can still connect to para_server
698 0.2.6. Use the new client option --plain to request an
699 uncrypted session (off by default, must be set to on in
700 order to connect to para_server 0.2.x with 0 <= x <= 5).
701 - para_server uses an internal function to locate audio files
702 rather than calling find(1). The server option
703 --mysql_audio_file_dir replaces --mysql_find_cmd.
704 - documentation update
705 - man pages
706 - header file cleanup
707 - para_client code cleanup
708 - para_gui: faster display of output of display commands
709
710 ------------------------------------------
711 0.2.5 (2005-10-13) "aggressive resolution"
712 ------------------------------------------
713
714 This release adds internal senders, i.e. no more external programs are
715 spawned for sending out the audio data. There are two different senders
716 available: The http sender and the ortp sender (former para_send which
717 is no longer needed).
718
719 The new sender code has a plugin-like design so it can be easily
720 extended should there be be any future need for supporting another
721 network streaming protocol. All senders are completely independent of
722 each other. In particular, the http and the ortp sender can operate
723 in parallel.
724
725 - new server command: sender to control senders at runtime.
726 Read the output of "para_server -h" and "para_client help
727 sender" for more information.
728 - para_recv renamed to para_ortp_recv
729 - new executable: para_http_recv, a simple command line
730 http receiver.
731 - major afs/mp3/ogg code simplifications due to internal
732 senders.
733 - ogg timing improvements
734 - fix several minor memory leaks (found by valgrind)
735 - empty stream definitions work again
736 - com_ne(): ignore errors on remove
737 - audiod: fix segfault on server restart
738
739 ---------------------------------------
740 0.2.4 (2005-09-21) "toxic anticipation"
741 ---------------------------------------
742
743 Several small improvements, fixes and the new grab command.
744
745 - audiod:
746 - new command: "grab" to grab the output of the stream reader
747 or any filters. Read the output of "para_audioc help grab"
748 for more information.
749 - fix memory leak
750 - code cleanup
751 - audioc: new command line option: --bufsize to specify a
752 buffer size different from the default size 8192.
753 - improved error diagnostics for para_play.
754 - new configure option: --enable-ssldir so search for openssl in
755 non-standard places
756 - sdl_gui: Make it look nice again for 1024x768
757 - server: report total size of memory allocated with sbrk by malloc,
758 new command line option: --announce_time
759
760 -----------------------------------------
761 0.2.3 (2005-09-01) "hydrophilic movement"
762 -----------------------------------------
763
764 Two new executables and major feature enhancements.
765
766 - audiod filters: It is now possible to specify arbitrary many
767 (including none) filters for each supported audio
768 format. This can be used e.g. for normalizing volume,
769 transforming or grabbing the audio stream, or for using
770 visualizers. Read the output of "para_audiod -h" for the
771 syntax of the new --filter_cmd option.
772 - new executable: para_play, a tiny alsa player. It
773 can play wave files or raw pcm (16 bit little endian)
774 from stdin.
775 - new executable: para_compress, a dynamic range compressor
776 intended to keep audio output at a consistent volume. Derived
777 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
778 - audiod: New option: --stream_delay. This can be used in
779 a local network to syncronize the audio output of all
780 clients that play the same stream.
781
782 ------------------------------------------
783 0.2.2 (2005-08-19) "tangential excitation"
784 ------------------------------------------
785
786 Mostly internal changes in this release, but also some new commands
787 for the mysql database tool.
788
789 - cleanup exec.c, fix para_exec bug
790 - compile time loglevel (log messages below the given level
791 won't be compiled in, which reduces the size of the
792 resulting binaries)
793 - new log macros that shorten the size of the source code.
794 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
795 to send only zeros. With this workaround, para_audioc works
796 again.
797 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
798 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
799 (new entry), "snp" (set numplayed). Read the manual for more
800 information.
801
802 ---------------------------------------
803 0.2.1 (2005-08-15) "surreal experience"
804 ---------------------------------------
805
806 Here comes paraslash-0.2.1. It contains a couple of new features and,
807 surprise, only minor bug fixes.
808
809 - kill noisy mp3 debug message
810 - cleanup of the build system
811 - para_server and para_client directly use the crypto routines
812 of the openssl library rather than invoking the openssl command
813 line utitlity
814 - server/audiod: new option --user to switch to the given user
815 when invoked as root. Read the output of "para_server -h" for
816 more information.
817 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
818 status. Default: "para_audioc stat"
819 - sdl_gui: new option --pic_cmd to be used to download the picture.
820 Default: "para_client pic"
821 - audiod: 5 slots ought to be enough for everybody
822 - audiod: new status item: Uptime, kill hup command
823
824 ------------------------------------------
825 0.2.0 (2005-08-06) "distributed diffusion"
826 ------------------------------------------
827
828 After several month of increased development activity, paraslash-0.2.0
829 has arrived. It contains many new features and is much more
830 self-contained than the old 0.1.x series. Enjoy!
831
832
833 - para_server: fix hang on song change and crash on sighup.
834 Speed up mysql queries. The DIR_LIKE macro is gone.
835 - new executables: para_audiod, the local audio daemon that
836 starts playback (uses SCM_CREDENTIALS socket magic) and
837 para_audioc, the corresponding client.
838 - new executables: para_mp3dec/para_oggdec, two really teensy
839 decoders. para_mp3dec is based on libmad, para_oggdec requires
840 libvorbisfile.
841 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
842 they are now called para_send and para_recv respectively.
843 - documentation updates
844 - para_gui is themable. For now there is the default theme that
845 looks as before and the simple theme: blue and easy.
846 - gui: audio streaming is now handled by audiod. Time display shows
847 playback time rather than streaming time
848 - slider: update to libzmw-0.2.0
849 - para_krell: fix crash on server shutdown
850 - switch from gzip to bzip2
851
852 ----------------------------------------
853 0.1.7 (2005-04-18) "melting penetration"
854 ----------------------------------------
855
856 The main change in this release is clearly the oggvorbis rewrite,
857 but there are also lots of smaller changes. If you intend to use both
858 the mp3 and the ogg plugin, it is recommended to use software mixing,
859 e.g. the dmix plugin which is provided by ALSA.
860
861 - new executables: para_ovsend and para_ovrecv for sending/receiving
862 oggvorbis files via rtp. Requires the open rtp library. Get it at
863 http://www.linphone.org/ortp/
864 - rewrite of the ogg_vorbis core code
865 - configure detects libzmw and, if detected, includes
866 para_slider to the list of binaries to be built by make
867 - server stream writers read from their associated fifo rather
868 than from stdin
869 - slider: two new sliders, lastplayed and numplayed
870 - fix nasty double free bug which caused random segfaults in case of
871 mp3 files with invalid header information
872 - gui: new command line option: --stream_timeout=seconds to
873 deactivate a slot if it is idle for that many seconds (default=`5')
874 - diffstats
875
876 ---------------------------------------
877 0.1.6 (2005-03-05) "asymptotic balance"
878 ---------------------------------------
879
880 Only little user-visible changes in this release. Mainly bugfixes and
881 core code cleanup. This is probably the most stable version ever if you
882 stick to mp3...
883
884 - fix several memory leaks
885 - rename default name of mysql database from "music" to "paraslash".
886 Use para_server's --mysql_database option if you do not want to
887 rename your old database.
888 - rework ogg vorbis code
889 - make update command work on mysql servers with LOCAL_INFILE
890 disabled
891 - gui: improved stream I/O (slots)
892 - simplified audio format API
893 - para_pob_ogg is gone
894
895 ------------------------------------
896 0.1.5 (2004-12-31) "opaque eternity"
897 ------------------------------------
898
899 Let's slide gently into the new year.
900
901 - new: para_slider (not built automatically, type "make
902 para_slider" to build). A toy for those who always felt that
903 creating stream definitions is difficult. See screenshots,
904 README and FEATURES for more info.
905 - improved signal handling. Fixes server segfault on SIGHUP
906 for linux kernels newer than Aug 24 2004 and makes para_gui
907 race-free.
908 - reload database tool on SIGHUP
909 - improved help message for sl
910 - do not log "broken pipe" messages as errors. They are
911 perfectly ok.
912 - fix wrong error message on permission errors
913
914 -----------------------------------------
915 0.1.4 (2004-12-19) "tunneling transition"
916 -----------------------------------------
917
918 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
919 Hopefully, most of them got wiped out with this release. Some
920 enhancements went also in.
921
922 - improved error diagnostics for all commands
923 - stradd/picadd: overwrite previous contents if entry already
924 exists, rather than returning errors
925 - stradd: use current stream if invoked without args
926 - faster (and hopefully more stable) ogg-vorbis handling
927 - para_krell: reap children to avoid zombie-flooding in case
928 no server is running
929 - si: report also server pid
930 - server: don't busy-loop if dbtool reports only invalid files.
931 - gui: CTRL+C works again, fix stream_read command line option
932 - fix pic_add, hist
933 - fix mysql dbtool startup in case no database exists
934 - many small fixes and cleanups
935
936 ---------------------------------------
937 0.1.3: (2004-12-10) "vanishing inertia"
938 ---------------------------------------
939
940 Starting from this release, the database tools are integrated in the
941 server binary. This decreases server startup time, reduces code size
942 and speeds up database commands. However, the layout of the underlying
943 mysql database changed only slightly and 0.1.3 should be backwards
944 compatible in that respect.
945
946 Visible changes:
947
948 - If mysql is not detected at compile time, or fails to init
949 at runtime, fall back to the dopey database tool which should
950 always work.
951 - para_dbtool and dbtool.conf are gone. All mysql specific
952 options are read from server.conf and are prefixed by 'mysql_'.
953 - new command: cdt (change database tool)
954 - new command line option: dbtool (choose startup database tool)
955 - The name of current stream is now stored in the database,
956 so paraslash remembers its current stream when restarted.
957 - new command: csp (change stream and play)
958 - para_gui also reports current database tool and server uptime
959
960 -------------------------------------------
961 0.1.2: (2004-11-28) "spherical fluctuation"
962 -------------------------------------------
963
964 Point release before the big dbtool changes go in.
965
966 - dbtool: rename ca to cam (copy all meta data). It now also
967 copies numplayed and lastplayed time as well as the picture
968 id.
969 - fix endless-loop-bug caused by mp3 files with invalid header
970
971 -----------------------------------------
972 0.1.1: (2004-11-05) "floating atmosphere"
973 -----------------------------------------
974
975 - gkrellm plugin
976 - new dbtool command: mbox. Browse your sound-file collection
977 with your favorite mail reader.
978 - several small fixes
979
980 -------------------------------------
981 0.1.0: (2004-10-22) "rotating cortex"
982 -------------------------------------
983
984 - fix logging bug for loglevel > VERBOSE
985 - fix skip command
986 - correct timings for vbr mp3s
987 - modular audio format support
988 - ogg-vorbis support (experimental)
989 - new server option: autoplay
990
991 -----------------------------------------
992 0.0.99: (2004-07-25) "harmonic deviation"
993 -----------------------------------------
994
995 - rename projectname from icc to paraslash (play, archive, rate
996 and stream large audio sets happily)
997 - paraslash is no longer restricted to one particular audio
998 streaming software
999 - new dbtool commands (stradd, strq, strdel) for easy stream
1000 managment w/o configuration file. That obsoletes stream_defs
1001 file/config option for dbtool.
1002 - picadd accepts jpeg data from stdin
1003 - new server commands: ps (select previous stream), sc (song change)
1004 - new default pictures for sdl_gui
1005 - gui: new key_map option for binding commands and internal
1006 functions to arbitrary keys, nice help screen, rip out
1007 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1008 show silly logo on startup
1009 - new executables: para_fade for fading volume, para_dbadm for
1010 manipulating attributes
1011 - cdb adds _all_ tables to mysql database
1012 - revised and beautified documentation
1013 - sample dbtool rewritten in C
1014 - autoconf
1015
1016 ---------------------------------------------
1017 0.0.98: (2003-12-26) "incremental smoothness"
1018 ---------------------------------------------
1019
1020 - kick icecast in favour of poc. That removes some races and reduces
1021 core code considerably.
1022 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1023 give finer info on afs' status.
1024 - gui can start decoder (see config options). Further new gui
1025 commands: refresh (^L), jmp (F1-F10)
1026 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1027 terminates gui. This fixes dead instances consuming memory
1028 continuously.
1029 - new dbtool command: verb for sending verbatim sql queries.
1030 - fix pid_list races (by removing pid_list)
1031 - codename funnies
1032
1033 --------------------
1034 0.0.97: (2003-10-26)
1035 --------------------
1036
1037 - installation prefix now defaults to /usr/local
1038 - new commands for gui: snozze, sleep and reread config
1039 - config file for gui and sdl_gui
1040 - fix problems with filenames containing funny characters
1041 (reported by Thomas Forell)
1042 - improved signal handling for gui, now it rereads conf on SIGHUP
1043 - new dbtool command: cdb (create database)
1044 - switch from argtable to gengetopt
1045 - major code cleanup and speed improvements
1046 - fix several potential buffer overflows
1047 - many small fixes and cleanups
1048
1049 -------------------
1050 0.0.96 (2003-08-30)
1051 -------------------
