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 - Improved downloads web page.
14
15 -----------------------------------------
16 0.4.12 (2012-12-20) "volatile relativity"
17 -----------------------------------------
18 The new command line player, the resample filter, ALSA support for
19 para_fade, and the improved build system are the highlights of this
20 release which probably marks the end of the 0.4.x series.
21
22 - The afh receiver and the para_play executable.
23 - The resample filter: A sample rate converter based on
24 libsamplerate.
25 - The "versions" directory has been removed from the master
26 branch. The tarballs of the old releases are now available
27 in the new "releases" branch.
28 - Overhaul of the build system: All generated files are now
29 written to the "build" directory.
30 - The modular mixer API and the alsa mixer.
31 - Minor fixes for the osx writer.
32
33 --------------------------------------
34 0.4.11 (2012-07-20) "mutual diversity"
35 --------------------------------------
36
37 The major feature in this release is the new sideband API for
38 client-server communication. This API will be used exclusively starting
39 with 0.5.0, which breaks backward compatibility but allows to get rid
40 of quite some compatibility code. Other noteworthy changes include
41 decoder latency improvements and a long-standing bug fix for the
42 ALSA writer.
43
44 - Sideband connections: If both para_server and para_client
45 support this feature, data is sent as a multiplexed stream.
46 - The --no_default_filters option of para_filter has been
47 removed.
48 - Several fixes and latency improvements to various decoders.
49 - The ALSA writer now limits the prebuffer time to 500ms.
50 - Documentation improvements.
51 - Overhaul of the command_util.sh script.
52 - Fixes for some minor problems found by the clang analyzer.
53 - Compiles (almost) without warnings on gcc-3.
54 - Robustness improvements of the buffer tree code.
55
56 ------------------------------------------
57 0.4.10 (2012-03-30) "heterogeneous vacuum"
58 ------------------------------------------
59
60 Nothing earth-shaking in this release, but quite a few usability
61 improvements and the usual mix of cleanups and fixes.
62
63 - The --no_default_filters option of para_filter has been
64 deprecated. It still works but has no effect and will be
65 removed in the next version.
66 - para_gui now prints also the stderr output of the executing
67 command in the bottom window.
68 - Cleanup and consolidation of the various wrappers for
69 write(), writev(), send() and friends.
70 - The obscure error messages on mmap() failures have been
71 replaced by meaningful messages. This affects mainly
72 para_afh.
73 - para_audioc: Cleanups and memory leak fixes.
74 - Test 0004-server no longer fails if para_server is not
75 being built.
76 - New configure options: --with-id3tag-{headers,libs}.
77
78 -------------------------------------
79 0.4.9 (2011-12-06) "hybrid causality"
80 -------------------------------------
81
82 Support for another audio format, interactive mode for para_client
83 and para_audiod and many small improvements/fixes all over the place.
84
85 - Support for flac, the free lossless audio codec.
86 - Fix for an endless loop in the mp3 decoder for certain
87 (corrupt) mp3 files.
88 - When executed without specifying a command, para_client
89 and para_audioc start an interactive shell (requires
90 libreadline being installed). The interactive mode offers
91 full tab completion and command line history.
92 - autogen.sh now detects a distcc setup and adjusts the
93 parameter for the -j option of make accordingly.
94 - Shared memory areas are no longer restricted to 64K. We now
95 detect the maximal size of a shared memory area at runtime.
96 - cleanup of the internal uptime API.
97 - para_server prefaults the mmapped audio file to avoid
98 delays on slow media.
99 - A new test for the test-suite that exercises the
100 communication between para_server and para_audiod.
101 - The alsa writer eats up less CPU cycles when configured to
102 use the DMIX plugin.
103 - Simplified and unified receiver code.
104 - Makefile cleanups.
105 - Commands which print a list of matching audio files now
106 emit a meaningful error message if no audio file matched the
107 given pattern(s).
108
109 --------------------------------------
110 0.4.8 (2011-08-19) "nested assignment"
111 --------------------------------------
112
113 Gcrypt support, the overhauled osx writer and regex format specifiers
114 are the highlights of this release.
115
116 - support for libgcrypt as a drop-in replacement for openssl.
117 Run configure --enable-cryptolib=gcrypt to link against
118 libgcrypt. The two crypto implementations are compatible to
119 each other, i.e. a para_client executable linked against
120 gcrypt can connect to para_server linked against libssl
121 and vice versa.
122 - Rewrite of the osx writer (output plugin for Mac OS).
123 - audiod: The format specifier for receivers, filters and
124 writers is now treated as a regular expression. This allows
125 to replace 5 lines in the config file (one for each audio
126 format) by one single line. See the manual for details.
127 - The *.cmdline.[ch] files are no longer contained in the released
128 tarballs. This reduces the size of the tarballs but requires
129 gengetopt to build the tarball.
130 - Compiles cleanly also with llvm/clang.
131 - Corrupt mp3 files are handled more gracefully.
132 - The alsa writer uses poll fds instead of computing timeouts.
133 - Cleanup of the generic writer API.
134 - sched: Optimized zero timeouts.
135 - vss timeout cleanups.
136 - oggdec fixes and improvements.
137
138 --------------------------------------
139 0.4.7 (2011-06-01) "infinite rollback"
140 --------------------------------------
141
142 The new ao writer, support for ssh RSA keys and a couple of other
143 enhancements.
144
145 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
146 platforms through the libao audio library.
147 - Support for RSA keys generated with ssh-keygen.
148 - configure: improved options for ogg/vorbis/speex.
149 - The git version reported by --version always matches HEAD.
150 - The autogen script detects the number of processors and
151 runs a parallel make if possible.
152 - Major cleanup of the crypto API.
153 - Documentation updates.
154
155 ------------------------------------------
156 0.4.6 (2011-03-31) "deterministic entropy"
157 ------------------------------------------
158
159 Lots of ogg/vorbis improvements, the new test suite, enhancements
160 for para_gui and a fair amount of other bug fixes.
161
162 - For DCCP/OGG streams the audio file header is only sent once
163 at the beginning of the stream rather than periodically
164 every five seconds. This reduces network traffic and the
165 FEC group size.
166 - The vorbis comment header is replaced by an empty dummy header
167 before the header is sent over the network. This also results in
168 less network traffic and smaller FEC groups.
169 - The new "test" make target allows to perform some sanity checks prior
170 to installing the package.
171 - ogg timing fixes and performance improvements
172 - Scheduler improvements
173 - Proper exit codes for para_write
174 - para_gui: New option --theme to select a startup theme. Several
175 other improvements and fixes.
176 - aacdec error message cleanups
177 - simplified color error handling
178
179 --------------------------------------------
180 0.4.5 (2010-12-17) "symmetric randomization"
181 --------------------------------------------
182
183 Bug fixes, internal cleanups and variable-sized FEC slices.
184
185 - Contains a fix for an invalid-free-bug in the ogg audio format
186 handler code.
187 - Switching off the DCCP sender works again.
188 - para_audiod handles crashes of para_server more robustly.
189 - Internal scheduler and writer cleanups.
190 - Reduced latency due to variable-sized FEC slices.
191 - Improved documentation and error diagnostics.
192 - The build of para_server is now optional, allowing the build
193 to succeed in case libosl is not installed.
194
195 ------------------------------------------
196 0.4.4 (2010-08-06) "persistent regularity"
197 ------------------------------------------
198
199 Support for yet another audio format, para_write improvements and
200 bug fixes.
201
202 - Support for the speex codec.
203 - Support for sample formats other than 16 bit little endian.
204 - error2.h is now created by a perl script which speeds up configure
205 considerably.
206 - Fix a bug in the aac decoder which could lead to segfaults in
207 para_filter/para_audiod.
208 - Fixes for autoconf-2.66.
209
210 ----------------------------------------
211 0.4.3 (2010-07-05) "imaginary radiation"
212 ----------------------------------------
213
214 Many improvements for the DCCP and the UDP transport, the new user
215 manual and the usual mix of bug fixes and internal improvements.
216
217 - FEC support for the DCCP sender (Gerrit Renker). The new
218 --dccp_max_slice_size, --dccp_data_slices_per_group and
219 --dccp_slices_per_group options can be used to set the FEC
220 parameters for the DCCP transport.
221 - DNS lookups for UDP targets (Gerrit Renker).
222 - The new user manual replaces the README, README.afs, REQUIREMENTS
223 and INSTALL documents.
224 - Fix an end-of-file detection bug in the oggdec filter.
225 - The new nonblock API.
226 - Both options of the oggdec filter have been removed.
227 - New debug mode for the internal scheduler.
228
229 ------------------------------------------
230 0.4.2 (2010-04-23) "associative expansion"
231 ------------------------------------------
232
233 It's been some time since the last release, but finally here is
234 paraslash-0.4.2. The bulk of the changes comes from the new buffer
235 tree API, but there are changes all over the tree. Mainly performance
236 and usability improvements, but also quite some bug fixes.
237
238 - The new buffer tree API.
239 - DCCP: Support for CCID negotiation (Gerrit Renker).
240 - UDP robustness fixes.
241 - The --bufsize option for mp3dec is gone as it no longer makes sense
242 for the new buffer tree API.
243 - Fix audible buffer underruns for wma streams.
244 - The alsa writer no longer prints meaningless underrun durations.
245 - audiod: Defaults work also for udp streams. If no filter is
246 given for an audio format that is received via upd, fecdec is
247 automatically added as the first filter (along with the decoder).
248
249 ---------------------------------------
250 0.4.1 (2009-12-22) "concurrent horizon"
251 ---------------------------------------
252
253 Support for another audio format, minor feature enhancements and lots of bug
254 fixes. All fixes that have been accumulated in the maint branch (in particular
255 those mentionened in the 0.3.6 release notes) appear in this release as well.
256
257 - wma support.
258 - new afh option: --human to activate human-readable output.
259 - new server/audiod option: --log-timing to print timing information.
260 - build system improvements.
261 - source code documentation updates.
262
263 -------------------------------------
264 0.3.6 (2009-12-07) "cubic continuity"
265 -------------------------------------
266
267 Quite a few bugs have been found and fixed since 0.3.5, so here's
268 another 0.3.x release. No new features.
269
270 - Always check return value of malloc().
271 - ogg vorbis/FEC: Do not write garbage after the audio file header.
272 - exit if root privileges could not be dropped.
273 - FEC: Fix computation of extra slices.
274 - oss: Fix check for empty input buffer.
275 - Avoid buffer underruns due to filter chain output buffer constraints.
276 - server: Fix assignment of afs_pid.
277 - Don't panic if the afs database contains unknown audio formats.
278 - http/dccp: Do not send the audio file header twice.
279 - FEC: Timing improvements.
280
281 ----------------------------------------------
282 0.4.0 (2009-11-10) "simultaneous independence"
283 ----------------------------------------------
284
285 Two significant changes which require the new version number: The
286 improved authentication dialog and the fact that the database code
287 has been moved to a library, libosl. To use the new version, you have
288 to generate new RSA keys, see INSTALL for details. A shell script is
289 provided for conversion of the 0.3 database to the new 0.4 format.
290
291 - stronger crypto for client authentication
292 - the database code has been moved to a library
293 - improved status item handling
294 - cleanup of the build system
295 - The "-V" option now also prints the git version
296 - the new parser-friendly listing mode for the ls and stat commands
297 - mandatory rc4 encryption
298 - major audio format handler cleanups
299 - (id3,...) tags are no longer stored as a combined string in the database
300 - new mood methods: artist_matches, title_matches, comment_matches,
301 album_matches, year_maches, year.
302
303 --------------------------------------------
304 0.3.5 (2009-09-21) "symplectic separability"
305 --------------------------------------------
306
307 Full client support for *BSD Unixes, complete re-write of the ogg
308 vorbis audio format handler, various improvements all over the place
309 and the usual mix of bugfixes. This release marks the end of the 0.3
310 series if no serious problems show up.
311
312 - the new oss writer (supported on *BSD and Linux)
313 - rewrite of the ogg vorbis audio format handler. It's
314 recommended to replace the chunk tables of existing ogg
315 vorbis files in the afs database by re-adding these files
316 with "add -f".
317 - support for netmask subsets (Gerrit Renker)
318 - the new prebuffer filter
319 - improved signal handling
320 - variable fec output buffer size
321 - improved FEC timing fixes audible buffer underruns in UDP mode
322 - --log_color actually works
323 - new ls option: -d (print dates as seconds after the epoch)
324 - update to gengetopt 2.22.2
325 - support for RSA keys of size > 512 bits
326 - new option "mixer_channel" for para_fade
327
328 -----------------------------------------
329 0.3.4 (2009-05-07) "elliptic inheritance"
330 -----------------------------------------
331
332 The new udp sender, forward error correction, colored logs and various
333 other improvements. As the udp sender does not depend on any special
334 libraries, it is built unconditionally.
335
336 - The udp sender replaces the ortp sender. The new code uses forward
337 error correction to protect against packet losses. Many thanks to
338 Gerrit Renker for providing ipv6 support.
339 - The default port for udp streaming now defaults to 8000, like
340 for the http and the dccp senders/receivers.
341 - Loglevels are now specified as symbolic names, e.g.
342 "--loglevel info".
343 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
344 - para_server/para_audiod: Color support for log messages.
345 - new options for mp3dec: --ignore-crc, --bufsize
346 - new audiod option: --config-file.
347 - gengetopt cleanups.
348 - Improved help/man pages: The documentation of para_audiod,
349 para_recv, para_filter and para_write now also contains
350 all options of the available receivers/filters/writers. The
351 man page of para_fade contains a description of the different
352 modes of operation.
353 - More source code documentation.
354 - vss timing fixes.
355
356 --------------------------------------------
357 0.3.3 (2008-12-01) "axiomatic perspectivity"
358 --------------------------------------------
359
360 Internal code cleanups, bug fixes, improved tag handling and the new
361 amplification filter.
362
363 - para_server uses the generic scheduling code.
364 - overhaul of the virtual streaming system.
365 - mp3: id3 version 2 support via libid3tag (optional)
366 - ogg: vorbis comment support.
367 - aac meta info support.
368 - mp3 audio format handler cleanups.
369 - new filter: "amp" to amplify the amplitude of the audio stream
370 - new status item/database entry: amplification. It is
371 used by the amp filter to pre-amplify the audio stream.
372 - fix a close-without-open bug in para_write.
373 - fix a bug in com_init() which was introduced in 0.3.2.
374 - better error diagnostics for para_client.
375
376 -----------------------------------------
377 0.3.2 (2008-04-11) "probabilistic parity"
378 -----------------------------------------
379
380 The new para_afh executable, scheduling and documentation improvements.
381
382 - new ls option: -lc (list chunk table)
383 - new executable: para_afh, the stand-alone audio file handler tool
384 - afs commands can send output more than SHMMAX (32MB on Linux). This
385 also reduces the memory usage of commands that produce large amounts
386 of output.
387 - major scheduler and audiod cleanups.
388 - more detailed and much nicer man pages.
389
390 ---------------------------------------
391 0.3.1 (2008-02-23) "liquid interaction"
392 ---------------------------------------
393
394 A mix of cleanups, bug fixes, improvements, and some new features. No
395 significant changes to the new database (osl) code, which is generally
396 a good sign.
397
398 - Share some similar/duplicate code between the http and the
399 dccp sender.
400 - Generic access control lists for paraslash senders.
401 - dccp sender: Access control lists, connection limiting and support
402 for the allow,deny,on,off,help sender commands.
403 - The default dccp port changed from 5001 to 8000 (suggested by
404 Gerrit Renker).
405 - para_server starts even if not all public keys could be loaded.
406 - Audiod performance improvements.
407 - fix a bug in the "off" command of the http sender.
408 - fix some fd and memory leaks.
409 - Update to gengetopt-2.22.
410
411 -------------------------------------
412 0.3.0 (2008-01-12) "solar saturation"
413 -------------------------------------
414
415 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
416
417
418 Usually one might expect lots of new features AND a big increase in size
419 for a major release like this.
420
421 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
422 ever. The decrease in size is mostly due to the removal of some
423 graphical tools (which were only quick hacks anyway). But also the
424 fact that the mysql code is gone cuts down the size a bit.
425
426 Being independent of mysql comes at a cost: The fact that paraslash
427 now contains its own database (the object storage layer, osl) increases
428 the (stripped) binary size of para_server by ~50K on i386.
429
430 - no more restrictions on unique basenames.
431 - independent of mysql: The new self-contained object
432 storage layer (osl) replaces the mysql database.
433 - New executable para_fsck: Check integrity of osl tables.
434 - Lyrics support.
435 - Reliable audio file move/rename detection.
436 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
437 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
438 Solaris (sparc64).
439 - the new osl-based audio file selector (afs) replaces the random,
440 the playlist and the mysql selector of paraslash-0.2.x.
441 - IPv6 support (thanks to Gerrit Renker).
442 - paraslash-0.2.x streams are now called "moods". Writing
443 0.3.x-mood definitions should be both easier and more
444 powerful than writing 0.2.x-stream definitions.
445 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
446 been removed. The world is a better place without them. However,
447 para_gui is still there.
448 - afs tracks audio file selection also in playlist mode.
449 - few easy-to-use afs commands replace the many not-so-easy-to-use
450 mysql commands (and are available also in playlist mode).
451 - Improved error subsystem.
452 - The earth-shaking new logo.
453
454 -----------------------------------------
455 0.2.17 (2007-11-20) "isotropic threshold"
456 -----------------------------------------
457
458 Mainly bugfixes and cleanups in this version which marks the end of
459 the 0.2.x series if no serious bugs show up after the release.
460
461 - mysql_selector: fix a locking bug.
462 - universal chunk queueing.
463 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
464 to Gerrit Renker).
465 - be more carful wrt. signed vs. unsigned argument passing.
466 - cleanup error.h and fix some references to invalid error
467 codes.
468 - update to gengetopt-2.21.
469 - update to ortp-0.13.1.
470 - autoconf: extend checks for headers, library functions and
471 compiler characteristics.
472 - Fix streaming of large mp3 files.
473 - Fix an off-by-one bug in playlist handling.
474
475 --------------------------------------
476 0.2.16 (2007-04-05) "neural discharge"
477 --------------------------------------
478
479 The main change in this release is the major audio format handler
480 cleanup which removes some similar/duplicate code and makes it easier
481 to implement plugins for other audio formats. Of course, the usual mix
482 of other improvements/changes/bugfixes also made it into the release.
483
484 - simplified audio format handlers (most of the handling functions
485 were moved one layer up to the virtual streaming system).
486 - para_server uses mmap to read audio files
487 - repositioning of mp3 streams is much faster, in particular for
488 jumping near the end of large mp3 files.
489 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
490 and AFS_WRITE.
491 - fix a bug in para_filter that caused decoding of aac files
492 to start only after a few seconds.
493 - fix osx_writer hangs
494 - simplified dccp code (thanks to Gerrit Renker)
495 - the compress filter works also on big endian systems (ppc)
496
497 -----------------------------------------
498 0.2.15 (2007-02-16) "inductive resonance"
499 -----------------------------------------
500
501 Minor improvements, more documentation and a bunch of bug fixes.
502
503 - para_server: The server.users file is only read once on server
504 startup rather than for each connection
505 - mp3dec: Fix decoding of corrupt mp3 files
506 - afs (audio file sender) is now called vss (virtual streaming
507 system). Consequently, the permission flags specified in
508 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
509 become VSS_READ and VSS_WRITE respectively.
510 - para_audiod/para_filter: Fix a bug that caused the last chunk
511 of audio data not being written under certain circumstances
512 - audiod: compute the difference of server time and local time
513 correctly
514 - para_server/para_audiod: Fix some memory leaks
515 - documentation improvements
516 - configure.ac: fix checks for para_krell
517 - new man pages
518
519 -------------------------------------------
520 0.2.14 (2006-10-15) "transient singularity"
521 -------------------------------------------
522
523 The only major enhancement of this version is the osx writer which completes
524 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
525 until now for reasons beyond the scope of this changelog entry.
526
527 - new output plugin for Mac Os: the osx writer
528 - rename configure command line options from --enable-xxx-headers to
529 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
530 - configure: new command line options: --with-mad-headers,
531 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
532 - some robustness fixes
533 - dymamic audio format recognition for audiod
534 - para_server: new command line option: --autoplay_delay
535 - para_audiod: new command line option: --clock_diff_count
536
537 ---------------------------------------
538 0.2.13 (2006-07-14) "sonic convolution"
539 ---------------------------------------
540
541 A bunch of new features and core changes.
542
543 - the new paraslash scheduler, short and sweet.
544 - Support for m4a/mp4 files via the new aac audio format
545 handler/filter (requires libfaad).
546 - each writer has its own command line parser, just like
547 para_recv and para_filter.
548 - para_client and para_audioc use the error subsystem
549 - writers are integrated in para_audiod (currently linux-only)
550 - para_client is integrated in para_audiod
551 - random/playlist selector: improved info strings
552 - new audiod commands: tasks, kill
553 - update to libortp-0.10.1
554 - para_fade: wake time defaults to 8 hours from now
555 - update to autoconf-2.60
556
557 ------------------------------------------
558 0.2.12 (2006-05-12) "oriented abstraction"
559 ------------------------------------------
560
561 Many user-visible changes in this release and lots of new
562 features:
563
564
565 - the new optional dccp sender/receiver. It uses the datagram
566 congestion control protocol. You'll need a fairly new kernel
567 for this.
568 - paraslash works on Mac OS X (thanks to Gerd Becker)
569 - para_play renamed to para_write
570 - modular output plugin design (writers) for para_write
571 - new file_writer output plugin for para_write
572 - compress filter speed improvements
573 - update to libortp-0.9.1
574 - update to gengetopt-2.17rc
575 - para_client no longer depends on libreadline (as the
576 code for the interactive mode was removed).
577 - gcc-2-95 is no longer a supported compiler. It may still
578 work, but it gets no more testing.
579 - the tarball no longer contains the screenshot images which
580 reduces its size quite a bit.
581 - configure: new command line options: --enable-mysql-headers
582 and --enable-mysql-libs
583
584 ------------------------------------
585 0.2.11 (2006-03-11) "atomic duality"
586 ------------------------------------
587
588 Here it is, the first paraslash release developed with git. There
589 are fairly many user-visible changes in this release. As two out of
590 the three "database tools" of paraslash don't use a database at all,
591 they are now called "audio file selectors" instead.
592
593
594 - the cdt command (change database tool) becomes chs (change
595 selector)
596 - no more colon separators: The syntax of some options of
597 para_audiod and para_filter have changed. Use --help for
598 more info (and some examples).
599 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
600 - switch from cvs to git (should've done that earlier)
601 - the new ipc subsystem
602 - new audio file selector: playlist
603 - para_server: the dopey selector is now called "random",
604 and is the default selector. Use the --selector option to
605 choose another selector at startup, or the chs command to
606 change the selector at runtime.
607 - X86_64 fixes (thanks to Steffen Klassert)
608 - para_play fixes
609
610 --------------------------------------
611 0.2.10 (2006-02-17) "cyclic attractor"
612 --------------------------------------
613
614 Huge documentation update, a scrollable window for para_gui, ortp
615 improvements, and of course many small fixes not mentioned here.
616 The diffstat below is rather misleading as most insertions are due
617 to the new source documentation.
618
619 - autoconf cleanup
620 - para_server also uses the new error subsystem
621 - lots of new documentation (UTSL)
622 - gui improvements:
623 - keysyms for cursor keys and for next/previous page keys
624 - scrollable output window
625 - new internal commands: scroll up/down, page up/down
626 - fix color of command output.
627 - ortp: the --chunk_time and --header flags are no longer needed
628 for para_recv/para_audiod as this information is now encoded in
629 each rtp packet sent by para_server.
630
631 -------------------------------------------
632 0.2.9 (2006-01-24) "progressive turbulence"
633 -------------------------------------------
634
635 Internal audiod receivers/filters, the new error subsystem and
636 a lot of small improvements.
637
638 - para_recv and para_filter are integrated into the para_audiod
639 binary, i.e. audiod no longer spawns a new process for
640 each receiver/filter. As para_recv and para_filter might be
641 useful as standalone programs, they still get built (linked
642 against the same object files that are also used for audiod).
643 - further ortp timing improvements should reduce the CPU usage
644 of the ortp receiver.
645 - improved audio grabbing. The 'grab' command of para_audiod
646 has its own set of command line options. Read the output of
647 "para_audioc help grab" for more info.
648 - oggdec: configurable input prebuffer size.
649 - the new error subsystem gives better error diagnostics
650 and reduces code size.
651
652 -----------------------------------------
653 0.2.8 (2006-01-02) "dynamic accumulation"
654 -----------------------------------------
655
656 The new modular filter design and the para_play-hangs bugfix.
657
658 - new executable: para_filter. It combines para_mp3dec,
659 para_oggdec and para_compress. It also adds a further filter
660 type, wav, that just inserts a wave header at the desired point
661 of the filter chain. All 'piping' is done in-memory (i.e. no
662 read/write operations are used).
663 - para_play: fix a stupid bug that caused it to hang under
664 certain circumstances.
665
666 -------------------------------------------
667 0.2.7 (2006-12-27) "transparent invariance"
668 -------------------------------------------
669
670 Not many user-visible changes but a fair amount of internal improvements.
671
672
673 - The http sender buffers data if it can not be sent
674 out immediately (because the socket is not writable). This
675 should prevent para_server from shutting down the connection
676 too early on a loaded network.
677 - para_play also prebuffers data if it is told to start at a
678 future time by the --start_time option.
679 - The return of para_recv: It combines para_ortp_recv and
680 para_http_recv. Use the --receiver option to switch between
681 the two. para_recv builds without libortp, but contains
682 only the http receiver in this case.
683 - update to ortp 0.8.1. As this ortp release contains incompatible
684 changes, para_recv-0.2.7 won't link against older ortp libs.
685 - improved ortp timings.
686 - use of gcc-extensions that #define away for non-gcc and
687 gcc < 3.0.
688
689 -------------------------------------------
690 0.2.6 (2005-10-29) "recursive compensation"
691 -------------------------------------------
692
693 Transparent session encryption (uses openssl's Alleged RC4 cipher),
694 the internal find command and several other improvements and cleanups.
695
696 - Encrypt the session if encryption is requested by the client
697 (default for para_client 0.2.6). This is backwards
698 compatible, so older clients can still connect to para_server
699 0.2.6. Use the new client option --plain to request an
700 uncrypted session (off by default, must be set to on in
701 order to connect to para_server 0.2.x with 0 <= x <= 5).
702 - para_server uses an internal function to locate audio files
703 rather than calling find(1). The server option
704 --mysql_audio_file_dir replaces --mysql_find_cmd.
705 - documentation update
706 - man pages
707 - header file cleanup
708 - para_client code cleanup
709 - para_gui: faster display of output of display commands
710
711 ------------------------------------------
712 0.2.5 (2005-10-13) "aggressive resolution"
713 ------------------------------------------
714
715 This release adds internal senders, i.e. no more external programs are
716 spawned for sending out the audio data. There are two different senders
717 available: The http sender and the ortp sender (former para_send which
718 is no longer needed).
719
720 The new sender code has a plugin-like design so it can be easily
721 extended should there be be any future need for supporting another
722 network streaming protocol. All senders are completely independent of
723 each other. In particular, the http and the ortp sender can operate
724 in parallel.
725
726 - new server command: sender to control senders at runtime.
727 Read the output of "para_server -h" and "para_client help
728 sender" for more information.
729 - para_recv renamed to para_ortp_recv
730 - new executable: para_http_recv, a simple command line
731 http receiver.
732 - major afs/mp3/ogg code simplifications due to internal
733 senders.
734 - ogg timing improvements
735 - fix several minor memory leaks (found by valgrind)
736 - empty stream definitions work again
737 - com_ne(): ignore errors on remove
738 - audiod: fix segfault on server restart
739
740 ---------------------------------------
741 0.2.4 (2005-09-21) "toxic anticipation"
742 ---------------------------------------
743
744 Several small improvements, fixes and the new grab command.
745
746 - audiod:
747 - new command: "grab" to grab the output of the stream reader
748 or any filters. Read the output of "para_audioc help grab"
749 for more information.
750 - fix memory leak
751 - code cleanup
752 - audioc: new command line option: --bufsize to specify a
753 buffer size different from the default size 8192.
754 - improved error diagnostics for para_play.
755 - new configure option: --enable-ssldir so search for openssl in
756 non-standard places
757 - sdl_gui: Make it look nice again for 1024x768
758 - server: report total size of memory allocated with sbrk by malloc,
759 new command line option: --announce_time
760
761 -----------------------------------------
762 0.2.3 (2005-09-01) "hydrophilic movement"
763 -----------------------------------------
764
765 Two new executables and major feature enhancements.
766
767 - audiod filters: It is now possible to specify arbitrary many
768 (including none) filters for each supported audio
769 format. This can be used e.g. for normalizing volume,
770 transforming or grabbing the audio stream, or for using
771 visualizers. Read the output of "para_audiod -h" for the
772 syntax of the new --filter_cmd option.
773 - new executable: para_play, a tiny alsa player. It
774 can play wave files or raw pcm (16 bit little endian)
775 from stdin.
776 - new executable: para_compress, a dynamic range compressor
777 intended to keep audio output at a consistent volume. Derived
778 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
779 - audiod: New option: --stream_delay. This can be used in
780 a local network to syncronize the audio output of all
781 clients that play the same stream.
782
783 ------------------------------------------
784 0.2.2 (2005-08-19) "tangential excitation"
785 ------------------------------------------
786
787 Mostly internal changes in this release, but also some new commands
788 for the mysql database tool.
789
790 - cleanup exec.c, fix para_exec bug
791 - compile time loglevel (log messages below the given level
792 won't be compiled in, which reduces the size of the
793 resulting binaries)
794 - new log macros that shorten the size of the source code.
795 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
796 to send only zeros. With this workaround, para_audioc works
797 again.
798 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
799 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
800 (new entry), "snp" (set numplayed). Read the manual for more
801 information.
802
803 ---------------------------------------
804 0.2.1 (2005-08-15) "surreal experience"
805 ---------------------------------------
806
807 Here comes paraslash-0.2.1. It contains a couple of new features and,
808 surprise, only minor bug fixes.
809
810 - kill noisy mp3 debug message
811 - cleanup of the build system
812 - para_server and para_client directly use the crypto routines
813 of the openssl library rather than invoking the openssl command
814 line utitlity
815 - server/audiod: new option --user to switch to the given user
816 when invoked as root. Read the output of "para_server -h" for
817 more information.
818 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
819 status. Default: "para_audioc stat"
820 - sdl_gui: new option --pic_cmd to be used to download the picture.
821 Default: "para_client pic"
822 - audiod: 5 slots ought to be enough for everybody
823 - audiod: new status item: Uptime, kill hup command
824
825 ------------------------------------------
826 0.2.0 (2005-08-06) "distributed diffusion"
827 ------------------------------------------
828
829 After several month of increased development activity, paraslash-0.2.0
830 has arrived. It contains many new features and is much more
831 self-contained than the old 0.1.x series. Enjoy!
832
833
834 - para_server: fix hang on song change and crash on sighup.
835 Speed up mysql queries. The DIR_LIKE macro is gone.
836 - new executables: para_audiod, the local audio daemon that
837 starts playback (uses SCM_CREDENTIALS socket magic) and
838 para_audioc, the corresponding client.
839 - new executables: para_mp3dec/para_oggdec, two really teensy
840 decoders. para_mp3dec is based on libmad, para_oggdec requires
841 libvorbisfile.
842 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
843 they are now called para_send and para_recv respectively.
844 - documentation updates
845 - para_gui is themable. For now there is the default theme that
846 looks as before and the simple theme: blue and easy.
847 - gui: audio streaming is now handled by audiod. Time display shows
848 playback time rather than streaming time
849 - slider: update to libzmw-0.2.0
850 - para_krell: fix crash on server shutdown
851 - switch from gzip to bzip2
852
853 ----------------------------------------
854 0.1.7 (2005-04-18) "melting penetration"
855 ----------------------------------------
856
857 The main change in this release is clearly the oggvorbis rewrite,
858 but there are also lots of smaller changes. If you intend to use both
859 the mp3 and the ogg plugin, it is recommended to use software mixing,
860 e.g. the dmix plugin which is provided by ALSA.
861
862 - new executables: para_ovsend and para_ovrecv for sending/receiving
863 oggvorbis files via rtp. Requires the open rtp library. Get it at
864 http://www.linphone.org/ortp/
865 - rewrite of the ogg_vorbis core code
866 - configure detects libzmw and, if detected, includes
867 para_slider to the list of binaries to be built by make
868 - server stream writers read from their associated fifo rather
869 than from stdin
870 - slider: two new sliders, lastplayed and numplayed
871 - fix nasty double free bug which caused random segfaults in case of
872 mp3 files with invalid header information
873 - gui: new command line option: --stream_timeout=seconds to
874 deactivate a slot if it is idle for that many seconds (default=`5')
875 - diffstats
876
877 ---------------------------------------
878 0.1.6 (2005-03-05) "asymptotic balance"
879 ---------------------------------------
880
881 Only little user-visible changes in this release. Mainly bugfixes and
882 core code cleanup. This is probably the most stable version ever if you
883 stick to mp3...
884
885 - fix several memory leaks
886 - rename default name of mysql database from "music" to "paraslash".
887 Use para_server's --mysql_database option if you do not want to
888 rename your old database.
889 - rework ogg vorbis code
890 - make update command work on mysql servers with LOCAL_INFILE
891 disabled
892 - gui: improved stream I/O (slots)
893 - simplified audio format API
894 - para_pob_ogg is gone
895
896 ------------------------------------
897 0.1.5 (2004-12-31) "opaque eternity"
898 ------------------------------------
899
900 Let's slide gently into the new year.
901
902 - new: para_slider (not built automatically, type "make
903 para_slider" to build). A toy for those who always felt that
904 creating stream definitions is difficult. See screenshots,
905 README and FEATURES for more info.
906 - improved signal handling. Fixes server segfault on SIGHUP
907 for linux kernels newer than Aug 24 2004 and makes para_gui
908 race-free.
909 - reload database tool on SIGHUP
910 - improved help message for sl
911 - do not log "broken pipe" messages as errors. They are
912 perfectly ok.
913 - fix wrong error message on permission errors
914
915 -----------------------------------------
916 0.1.4 (2004-12-19) "tunneling transition"
917 -----------------------------------------
918
919 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
920 Hopefully, most of them got wiped out with this release. Some
921 enhancements went also in.
922
923 - improved error diagnostics for all commands
924 - stradd/picadd: overwrite previous contents if entry already
925 exists, rather than returning errors
926 - stradd: use current stream if invoked without args
927 - faster (and hopefully more stable) ogg-vorbis handling
928 - para_krell: reap children to avoid zombie-flooding in case
929 no server is running
930 - si: report also server pid
931 - server: don't busy-loop if dbtool reports only invalid files.
932 - gui: CTRL+C works again, fix stream_read command line option
933 - fix pic_add, hist
934 - fix mysql dbtool startup in case no database exists
935 - many small fixes and cleanups
936
937 ---------------------------------------
938 0.1.3: (2004-12-10) "vanishing inertia"
939 ---------------------------------------
940
941 Starting from this release, the database tools are integrated in the
942 server binary. This decreases server startup time, reduces code size
943 and speeds up database commands. However, the layout of the underlying
944 mysql database changed only slightly and 0.1.3 should be backwards
945 compatible in that respect.
946
947 Visible changes:
948
949 - If mysql is not detected at compile time, or fails to init
950 at runtime, fall back to the dopey database tool which should
951 always work.
952 - para_dbtool and dbtool.conf are gone. All mysql specific
953 options are read from server.conf and are prefixed by 'mysql_'.
954 - new command: cdt (change database tool)
955 - new command line option: dbtool (choose startup database tool)
956 - The name of current stream is now stored in the database,
957 so paraslash remembers its current stream when restarted.
958 - new command: csp (change stream and play)
959 - para_gui also reports current database tool and server uptime
960
961 -------------------------------------------
962 0.1.2: (2004-11-28) "spherical fluctuation"
963 -------------------------------------------
964
965 Point release before the big dbtool changes go in.
966
967 - dbtool: rename ca to cam (copy all meta data). It now also
968 copies numplayed and lastplayed time as well as the picture
969 id.
970 - fix endless-loop-bug caused by mp3 files with invalid header
971
972 -----------------------------------------
973 0.1.1: (2004-11-05) "floating atmosphere"
974 -----------------------------------------
975
976 - gkrellm plugin
977 - new dbtool command: mbox. Browse your sound-file collection
978 with your favorite mail reader.
979 - several small fixes
980
981 -------------------------------------
982 0.1.0: (2004-10-22) "rotating cortex"
983 -------------------------------------
984
985 - fix logging bug for loglevel > VERBOSE
986 - fix skip command
987 - correct timings for vbr mp3s
988 - modular audio format support
989 - ogg-vorbis support (experimental)
990 - new server option: autoplay
991
992 -----------------------------------------
993 0.0.99: (2004-07-25) "harmonic deviation"
994 -----------------------------------------
995
996 - rename projectname from icc to paraslash (play, archive, rate
997 and stream large audio sets happily)
998 - paraslash is no longer restricted to one particular audio
999 streaming software
1000 - new dbtool commands (stradd, strq, strdel) for easy stream
1001 managment w/o configuration file. That obsoletes stream_defs
1002 file/config option for dbtool.
1003 - picadd accepts jpeg data from stdin
1004 - new server commands: ps (select previous stream), sc (song change)
1005 - new default pictures for sdl_gui
1006 - gui: new key_map option for binding commands and internal
1007 functions to arbitrary keys, nice help screen, rip out
1008 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1009 show silly logo on startup
1010 - new executables: para_fade for fading volume, para_dbadm for
1011 manipulating attributes
1012 - cdb adds _all_ tables to mysql database
1013 - revised and beautified documentation
1014 - sample dbtool rewritten in C
1015 - autoconf
1016
1017 ---------------------------------------------
1018 0.0.98: (2003-12-26) "incremental smoothness"
1019 ---------------------------------------------
1020
1021 - kick icecast in favour of poc. That removes some races and reduces
1022 core code considerably.
1023 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1024 give finer info on afs' status.
1025 - gui can start decoder (see config options). Further new gui
1026 commands: refresh (^L), jmp (F1-F10)
1027 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1028 terminates gui. This fixes dead instances consuming memory
1029 continuously.
1030 - new dbtool command: verb for sending verbatim sql queries.
1031 - fix pid_list races (by removing pid_list)
1032 - codename funnies
1033
1034 --------------------
1035 0.0.97: (2003-10-26)
1036 --------------------
1037
1038 - installation prefix now defaults to /usr/local
1039 - new commands for gui: snozze, sleep and reread config
1040 - config file for gui and sdl_gui
1041 - fix problems with filenames containing funny characters
1042 (reported by Thomas Forell)
1043 - improved signal handling for gui, now it rereads conf on SIGHUP
1044 - new dbtool command: cdb (create database)
1045 - switch from argtable to gengetopt
1046 - major code cleanup and speed improvements
1047 - fix several potential buffer overflows
1048 - many small fixes and cleanups
1049
1050 -------------------
1051 0.0.96 (2003-08-30)
1052 -------------------
