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