[paraslash.git] / NEWS
1 -------------------------------------------
2 0.4.11 (to be announced) "mutual diversity"
3 -------------------------------------------
4
5 - Sideband connections: If both para_server and para_client
6 support this feature, data is sent as a multiplexed stream.
7 - The --no_default_filters option of para_filter has been
8 removed.
9 - Several fixes and latency improvements to various decoders.
10 - The alsa writer now limits the prebuffer time to 500ms.
11 - Documentation improvements.
12
13 ------------------------------------------
14 0.4.10 (2012-03-30) "heterogeneous vacuum"
15 ------------------------------------------
16
17 Nothing earth-shaking in this release, but quite a few usability
18 improvements and the usual mix of cleanups and fixes.
19
20 - The --no_default_filters option of para_filter has been
21 deprecated. It still works but has no effect and will be
22 removed in the next version.
23 - para_gui now prints also the stderr output of the executing
24 command in the bottom window.
25 - Cleanup and consolidation of the various wrappers for
26 write(), writev(), send() and friends.
27 - The obscure error messages on mmap() failures have been
28 replaced by meaningful messages. This affects mainly
29 para_afh.
30 - para_audioc: Cleanups and memory leak fixes.
31 - Test 0004-server no longer fails if para_server is not
32 being built.
33 - New configure options: --with-id3tag-{headers,libs}.
34
35 -------------------------------------
36 0.4.9 (2011-12-06) "hybrid causality"
37 -------------------------------------
38
39 Support for another audio format, interactive mode for para_client
40 and para_audiod and many small improvements/fixes all over the place.
41
42 - Support for flac, the free lossless audio codec.
43 - Fix for an endless loop in the mp3 decoder for certain
44 (corrupt) mp3 files.
45 - When executed without specifying a command, para_client
46 and para_audioc start an interactive shell (requires
47 libreadline being installed). The interactive mode offers
48 full tab completion and command line history.
49 - autogen.sh now detects a distcc setup and adjusts the
50 parameter for the -j option of make accordingly.
51 - Shared memory areas are no longer restricted to 64K. We now
52 detect the maximal size of a shared memory area at runtime.
53 - cleanup of the internal uptime API.
54 - para_server prefaults the mmapped audio file to avoid
55 delays on slow media.
56 - A new test for the test-suite that exercises the
57 communication between para_server and para_audiod.
58 - The alsa writer eats up less CPU cycles when configured to
59 use the DMIX plugin.
60 - Simplified and unified receiver code.
61 - Makefile cleanups.
62 - Commands which print a list of matching audio files now
63 emit a meaningful error message if no audio file matched the
64 given pattern(s).
65
66 --------------------------------------
67 0.4.8 (2011-08-19) "nested assignment"
68 --------------------------------------
69
70 Gcrypt support, the overhauled osx writer and regex format specifiers
71 are the highlights of this release.
72
73 - support for libgcrypt as a drop-in replacement for openssl.
74 Run configure --enable-cryptolib=gcrypt to link against
75 libgcrypt. The two crypto implementations are compatible to
76 each other, i.e. a para_client executable linked against
77 gcrypt can connect to para_server linked against libssl
78 and vice versa.
79 - Rewrite of the osx writer (output plugin for Mac OS).
80 - audiod: The format specifier for receivers, filters and
81 writers is now treated as a regular expression. This allows
82 to replace 5 lines in the config file (one for each audio
83 format) by one single line. See the manual for details.
84 - The *.cmdline.[ch] files are no longer contained in the released
85 tarballs. This reduces the size of the tarballs but requires
86 gengetopt to build the tarball.
87 - Compiles cleanly also with llvm/clang.
88 - Corrupt mp3 files are handled more gracefully.
89 - The alsa writer uses poll fds instead of computing timeouts.
90 - Cleanup of the generic writer API.
91 - sched: Optimized zero timeouts.
92 - vss timeout cleanups.
93 - oggdec fixes and improvements.
94
95 --------------------------------------
96 0.4.7 (2011-06-01) "infinite rollback"
97 --------------------------------------
98
99 The new ao writer, support for ssh RSA keys and a couple of other
100 enhancements.
101
102 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
103 platforms through the libao audio library.
104 - Support for RSA keys generated with ssh-keygen.
105 - configure: improved options for ogg/vorbis/speex.
106 - The git version reported by --version always matches HEAD.
107 - The autogen script detects the number of processors and
108 runs a parallel make if possible.
109 - Major cleanup of the crypto API.
110 - Documentation updates.
111
112 ------------------------------------------
113 0.4.6 (2011-03-31) "deterministic entropy"
114 ------------------------------------------
115
116 Lots of ogg/vorbis improvements, the new test suite, enhancements
117 for para_gui and a fair amount of other bug fixes.
118
119 - For DCCP/OGG streams the audio file header is only sent once
120 at the beginning of the stream rather than periodically
121 every five seconds. This reduces network traffic and the
122 FEC group size.
123 - The vorbis comment header is replaced by an empty dummy header
124 before the header is sent over the network. This also results in
125 less network traffic and smaller FEC groups.
126 - The new "test" make target allows to perform some sanity checks prior
127 to installing the package.
128 - ogg timing fixes and performance improvements
129 - Scheduler improvements
130 - Proper exit codes for para_write
131 - para_gui: New option --theme to select a startup theme. Several
132 other improvements and fixes.
133 - aacdec error message cleanups
134 - simplified color error handling
135
136 --------------------------------------------
137 0.4.5 (2010-12-17) "symmetric randomization"
138 --------------------------------------------
139
140 Bug fixes, internal cleanups and variable-sized FEC slices.
141
142 - Contains a fix for an invalid-free-bug in the ogg audio format
143 handler code.
144 - Switching off the DCCP sender works again.
145 - para_audiod handles crashes of para_server more robustly.
146 - Internal scheduler and writer cleanups.
147 - Reduced latency due to variable-sized FEC slices.
148 - Improved documentation and error diagnostics.
149 - The build of para_server is now optional, allowing the build
150 to succeed in case libosl is not installed.
151
152 ------------------------------------------
153 0.4.4 (2010-08-06) "persistent regularity"
154 ------------------------------------------
155
156 Support for yet another audio format, para_write improvements and
157 bug fixes.
158
159 - Support for the speex codec.
160 - Support for sample formats other than 16 bit little endian.
161 - error2.h is now created by a perl script which speeds up configure
162 considerably.
163 - Fix a bug in the aac decoder which could lead to segfaults in
164 para_filter/para_audiod.
165 - Fixes for autoconf-2.66.
166
167 ----------------------------------------
168 0.4.3 (2010-07-05) "imaginary radiation"
169 ----------------------------------------
170
171 Many improvements for the DCCP and the UDP transport, the new user
172 manual and the usual mix of bug fixes and internal improvements.
173
174 - FEC support for the DCCP sender (Gerrit Renker). The new
175 --dccp_max_slice_size, --dccp_data_slices_per_group and
176 --dccp_slices_per_group options can be used to set the FEC
177 parameters for the DCCP transport.
178 - DNS lookups for UDP targets (Gerrit Renker).
179 - The new user manual replaces the README, README.afs, REQUIREMENTS
180 and INSTALL documents.
181 - Fix an end-of-file detection bug in the oggdec filter.
182 - The new nonblock API.
183 - Both options of the oggdec filter have been removed.
184 - New debug mode for the internal scheduler.
185
186 ------------------------------------------
187 0.4.2 (2010-04-23) "associative expansion"
188 ------------------------------------------
189
190 It's been some time since the last release, but finally here is
191 paraslash-0.4.2. The bulk of the changes comes from the new buffer
192 tree API, but there are changes all over the tree. Mainly performance
193 and usability improvements, but also quite some bug fixes.
194
195 - The new buffer tree API.
196 - DCCP: Support for CCID negotiation (Gerrit Renker).
197 - UDP robustness fixes.
198 - The --bufsize option for mp3dec is gone as it no longer makes sense
199 for the new buffer tree API.
200 - Fix audible buffer underruns for wma streams.
201 - The alsa writer no longer prints meaningless underrun durations.
202 - audiod: Defaults work also for udp streams. If no filter is
203 given for an audio format that is received via upd, fecdec is
204 automatically added as the first filter (along with the decoder).
205
206 ---------------------------------------
207 0.4.1 (2009-12-22) "concurrent horizon"
208 ---------------------------------------
209
210 Support for another audio format, minor feature enhancements and lots of bug
211 fixes. All fixes that have been accumulated in the maint branch (in particular
212 those mentionened in the 0.3.6 release notes) appear in this release as well.
213
214 - wma support.
215 - new afh option: --human to activate human-readable output.
216 - new server/audiod option: --log-timing to print timing information.
217 - build system improvements.
218 - source code documentation updates.
219
220 -------------------------------------
221 0.3.6 (2009-12-07) "cubic continuity"
222 -------------------------------------
223
224 Quite a few bugs have been found and fixed since 0.3.5, so here's
225 another 0.3.x release. No new features.
226
227 - Always check return value of malloc().
228 - ogg vorbis/FEC: Do not write garbage after the audio file header.
229 - exit if root privileges could not be dropped.
230 - FEC: Fix computation of extra slices.
231 - oss: Fix check for empty input buffer.
232 - Avoid buffer underruns due to filter chain output buffer constraints.
233 - server: Fix assignment of afs_pid.
234 - Don't panic if the afs database contains unknown audio formats.
235 - http/dccp: Do not send the audio file header twice.
236 - FEC: Timing improvements.
237
238 ----------------------------------------------
239 0.4.0 (2009-11-10) "simultaneous independence"
240 ----------------------------------------------
241
242 Two significant changes which require the new version number: The
243 improved authentication dialog and the fact that the database code
244 has been moved to a library, libosl. To use the new version, you have
245 to generate new RSA keys, see INSTALL for details. A shell script is
246 provided for conversion of the 0.3 database to the new 0.4 format.
247
248 - stronger crypto for client authentication
249 - the database code has been moved to a library
250 - improved status item handling
251 - cleanup of the build system
252 - The "-V" option now also prints the git version
253 - the new parser-friendly listing mode for the ls and stat commands
254 - mandatory rc4 encryption
255 - major audio format handler cleanups
256 - (id3,...) tags are no longer stored as a combined string in the database
257 - new mood methods: artist_matches, title_matches, comment_matches,
258 album_matches, year_maches, year.
259
260 --------------------------------------------
261 0.3.5 (2009-09-21) "symplectic separability"
262 --------------------------------------------
263
264 Full client support for *BSD Unixes, complete re-write of the ogg
265 vorbis audio format handler, various improvements all over the place
266 and the usual mix of bugfixes. This release marks the end of the 0.3
267 series if no serious problems show up.
268
269 - the new oss writer (supported on *BSD and Linux)
270 - rewrite of the ogg vorbis audio format handler. It's
271 recommended to replace the chunk tables of existing ogg
272 vorbis files in the afs database by re-adding these files
273 with "add -f".
274 - support for netmask subsets (Gerrit Renker)
275 - the new prebuffer filter
276 - improved signal handling
277 - variable fec output buffer size
278 - improved FEC timing fixes audible buffer underruns in UDP mode
279 - --log_color actually works
280 - new ls option: -d (print dates as seconds after the epoch)
281 - update to gengetopt 2.22.2
282 - support for RSA keys of size > 512 bits
283 - new option "mixer_channel" for para_fade
284
285 -----------------------------------------
286 0.3.4 (2009-05-07) "elliptic inheritance"
287 -----------------------------------------
288
289 The new udp sender, forward error correction, colored logs and various
290 other improvements. As the udp sender does not depend on any special
291 libraries, it is built unconditionally.
292
293 - The udp sender replaces the ortp sender. The new code uses forward
294 error correction to protect against packet losses. Many thanks to
295 Gerrit Renker for providing ipv6 support.
296 - The default port for udp streaming now defaults to 8000, like
297 for the http and the dccp senders/receivers.
298 - Loglevels are now specified as symbolic names, e.g.
299 "--loglevel info".
300 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
301 - para_server/para_audiod: Color support for log messages.
302 - new options for mp3dec: --ignore-crc, --bufsize
303 - new audiod option: --config-file.
304 - gengetopt cleanups.
305 - Improved help/man pages: The documentation of para_audiod,
306 para_recv, para_filter and para_write now also contains
307 all options of the available receivers/filters/writers. The
308 man page of para_fade contains a description of the different
309 modes of operation.
310 - More source code documentation.
311 - vss timing fixes.
312
313 --------------------------------------------
314 0.3.3 (2008-12-01) "axiomatic perspectivity"
315 --------------------------------------------
316
317 Internal code cleanups, bug fixes, improved tag handling and the new
318 amplification filter.
319
320 - para_server uses the generic scheduling code.
321 - overhaul of the virtual streaming system.
322 - mp3: id3 version 2 support via libid3tag (optional)
323 - ogg: vorbis comment support.
324 - aac meta info support.
325 - mp3 audio format handler cleanups.
326 - new filter: "amp" to amplify the amplitude of the audio stream
327 - new status item/database entry: amplification. It is
328 used by the amp filter to pre-amplify the audio stream.
329 - fix a close-without-open bug in para_write.
330 - fix a bug in com_init() which was introduced in 0.3.2.
331 - better error diagnostics for para_client.
332
333 -----------------------------------------
334 0.3.2 (2008-04-11) "probabilistic parity"
335 -----------------------------------------
336
337 The new para_afh executable, scheduling and documentation improvements.
338
339 - new ls option: -lc (list chunk table)
340 - new executable: para_afh, the stand-alone audio file handler tool
341 - afs commands can send output more than SHMMAX (32MB on Linux). This
342 also reduces the memory usage of commands that produce large amounts
343 of output.
344 - major scheduler and audiod cleanups.
345 - more detailed and much nicer man pages.
346
347 ---------------------------------------
348 0.3.1 (2008-02-23) "liquid interaction"
349 ---------------------------------------
350
351 A mix of cleanups, bug fixes, improvements, and some new features. No
352 significant changes to the new database (osl) code, which is generally
353 a good sign.
354
355 - Share some similar/duplicate code between the http and the
356 dccp sender.
357 - Generic access control lists for paraslash senders.
358 - dccp sender: Access control lists, connection limiting and support
359 for the allow,deny,on,off,help sender commands.
360 - The default dccp port changed from 5001 to 8000 (suggested by
361 Gerrit Renker).
362 - para_server starts even if not all public keys could be loaded.
363 - Audiod performance improvements.
364 - fix a bug in the "off" command of the http sender.
365 - fix some fd and memory leaks.
366 - Update to gengetopt-2.22.
367
368 -------------------------------------
369 0.3.0 (2008-01-12) "solar saturation"
370 -------------------------------------
371
372 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
373
374
375 Usually one might expect lots of new features AND a big increase in size
376 for a major release like this.
377
378 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
379 ever. The decrease in size is mostly due to the removal of some
380 graphical tools (which were only quick hacks anyway). But also the
381 fact that the mysql code is gone cuts down the size a bit.
382
383 Being independent of mysql comes at a cost: The fact that paraslash
384 now contains its own database (the object storage layer, osl) increases
385 the (stripped) binary size of para_server by ~50K on i386.
386
387 - no more restrictions on unique basenames.
388 - independent of mysql: The new self-contained object
389 storage layer (osl) replaces the mysql database.
390 - New executable para_fsck: Check integrity of osl tables.
391 - Lyrics support.
392 - Reliable audio file move/rename detection.
393 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
394 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
395 Solaris (sparc64).
396 - the new osl-based audio file selector (afs) replaces the random,
397 the playlist and the mysql selector of paraslash-0.2.x.
398 - IPv6 support (thanks to Gerrit Renker).
399 - paraslash-0.2.x streams are now called "moods". Writing
400 0.3.x-mood definitions should be both easier and more
401 powerful than writing 0.2.x-stream definitions.
402 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
403 been removed. The world is a better place without them. However,
404 para_gui is still there.
405 - afs tracks audio file selection also in playlist mode.
406 - few easy-to-use afs commands replace the many not-so-easy-to-use
407 mysql commands (and are available also in playlist mode).
408 - Improved error subsystem.
409 - The earth-shaking new logo.
410
411 -----------------------------------------
412 0.2.17 (2007-11-20) "isotropic threshold"
413 -----------------------------------------
414
415 Mainly bugfixes and cleanups in this version which marks the end of
416 the 0.2.x series if no serious bugs show up after the release.
417
418 - mysql_selector: fix a locking bug.
419 - universal chunk queueing.
420 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
421 to Gerrit Renker).
422 - be more carful wrt. signed vs. unsigned argument passing.
423 - cleanup error.h and fix some references to invalid error
424 codes.
425 - update to gengetopt-2.21.
426 - update to ortp-0.13.1.
427 - autoconf: extend checks for headers, library functions and
428 compiler characteristics.
429 - Fix streaming of large mp3 files.
430 - Fix an off-by-one bug in playlist handling.
431
432 --------------------------------------
433 0.2.16 (2007-04-05) "neural discharge"
434 --------------------------------------
435
436 The main change in this release is the major audio format handler
437 cleanup which removes some similar/duplicate code and makes it easier
438 to implement plugins for other audio formats. Of course, the usual mix
439 of other improvements/changes/bugfixes also made it into the release.
440
441 - simplified audio format handlers (most of the handling functions
442 were moved one layer up to the virtual streaming system).
443 - para_server uses mmap to read audio files
444 - repositioning of mp3 streams is much faster, in particular for
445 jumping near the end of large mp3 files.
446 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
447 and AFS_WRITE.
448 - fix a bug in para_filter that caused decoding of aac files
449 to start only after a few seconds.
450 - fix osx_writer hangs
451 - simplified dccp code (thanks to Gerrit Renker)
452 - the compress filter works also on big endian systems (ppc)
453
454 -----------------------------------------
455 0.2.15 (2007-02-16) "inductive resonance"
456 -----------------------------------------
457
458 Minor improvements, more documentation and a bunch of bug fixes.
459
460 - para_server: The server.users file is only read once on server
461 startup rather than for each connection
462 - mp3dec: Fix decoding of corrupt mp3 files
463 - afs (audio file sender) is now called vss (virtual streaming
464 system). Consequently, the permission flags specified in
465 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
466 become VSS_READ and VSS_WRITE respectively.
467 - para_audiod/para_filter: Fix a bug that caused the last chunk
468 of audio data not being written under certain circumstances
469 - audiod: compute the difference of server time and local time
470 correctly
471 - para_server/para_audiod: Fix some memory leaks
472 - documentation improvements
473 - configure.ac: fix checks for para_krell
474 - new man pages
475
476 -------------------------------------------
477 0.2.14 (2006-10-15) "transient singularity"
478 -------------------------------------------
479
480 The only major enhancement of this version is the osx writer which completes
481 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
482 until now for reasons beyond the scope of this changelog entry.
483
484 - new output plugin for Mac Os: the osx writer
485 - rename configure command line options from --enable-xxx-headers to
486 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
487 - configure: new command line options: --with-mad-headers,
488 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
489 - some robustness fixes
490 - dymamic audio format recognition for audiod
491 - para_server: new command line option: --autoplay_delay
492 - para_audiod: new command line option: --clock_diff_count
493
494 ---------------------------------------
495 0.2.13 (2006-07-14) "sonic convolution"
496 ---------------------------------------
497
498 A bunch of new features and core changes.
499
500 - the new paraslash scheduler, short and sweet.
501 - Support for m4a/mp4 files via the new aac audio format
502 handler/filter (requires libfaad).
503 - each writer has its own command line parser, just like
504 para_recv and para_filter.
505 - para_client and para_audioc use the error subsystem
506 - writers are integrated in para_audiod (currently linux-only)
507 - para_client is integrated in para_audiod
508 - random/playlist selector: improved info strings
509 - new audiod commands: tasks, kill
510 - update to libortp-0.10.1
511 - para_fade: wake time defaults to 8 hours from now
512 - update to autoconf-2.60
513
514
515 ------------------------------------------
516 0.2.12 (2006-05-12) "oriented abstraction"
517 ------------------------------------------
518
519 Many user-visible changes in this release and lots of new
520 features:
521
522
523 - the new optional dccp sender/receiver. It uses the datagram
524 congestion control protocol. You'll need a fairly new kernel
525 for this.
526 - paraslash works on Mac OS X (thanks to Gerd Becker)
527 - para_play renamed to para_write
528 - modular output plugin design (writers) for para_write
529 - new file_writer output plugin for para_write
530 - compress filter speed improvements
531 - update to libortp-0.9.1
532 - update to gengetopt-2.17rc
533 - para_client no longer depends on libreadline (as the
534 code for the interactive mode was removed).
535 - gcc-2-95 is no longer a supported compiler. It may still
536 work, but it gets no more testing.
537 - the tarball no longer contains the screenshot images which
538 reduces its size quite a bit.
539 - configure: new command line options: --enable-mysql-headers
540 and --enable-mysql-libs
541
542 ------------------------------------
543 0.2.11 (2006-03-11) "atomic duality"
544 ------------------------------------
545
546 Here it is, the first paraslash release developed with git. There
547 are fairly many user-visible changes in this release. As two out of
548 the three "database tools" of paraslash don't use a database at all,
549 they are now called "audio file selectors" instead.
550
551
552 - the cdt command (change database tool) becomes chs (change
553 selector)
554 - no more colon separators: The syntax of some options of
555 para_audiod and para_filter have changed. Use --help for
556 more info (and some examples).
557 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
558 - switch from cvs to git (should've done that earlier)
559 - the new ipc subsystem
560 - new audio file selector: playlist
561 - para_server: the dopey selector is now called "random",
562 and is the default selector. Use the --selector option to
563 choose another selector at startup, or the chs command to
564 change the selector at runtime.
565 - X86_64 fixes (thanks to Steffen Klassert)
566 - para_play fixes
567
568
569 --------------------------------------
570 0.2.10 (2006-02-17) "cyclic attractor"
571 --------------------------------------
572
573 Huge documentation update, a scrollable window for para_gui, ortp
574 improvements, and of course many small fixes not mentioned here.
575 The diffstat below is rather misleading as most insertions are due
576 to the new source documentation.
577
578 - autoconf cleanup
579 - para_server also uses the new error subsystem
580 - lots of new documentation (UTSL)
581 - gui improvements:
582 - keysyms for cursor keys and for next/previous page keys
583 - scrollable output window
584 - new internal commands: scroll up/down, page up/down
585 - fix color of command output.
586 - ortp: the --chunk_time and --header flags are no longer needed
587 for para_recv/para_audiod as this information is now encoded in
588 each rtp packet sent by para_server.
589
590
591 -------------------------------------------
592 0.2.9 (2006-01-24) "progressive turbulence"
593 -------------------------------------------
594
595 Internal audiod receivers/filters, the new error subsystem and
596 a lot of small improvements.
597
598 - para_recv and para_filter are integrated into the para_audiod
599 binary, i.e. audiod no longer spawns a new process for
600 each receiver/filter. As para_recv and para_filter might be
601 useful as standalone programs, they still get built (linked
602 against the same object files that are also used for audiod).
603 - further ortp timing improvements should reduce the CPU usage
604 of the ortp receiver.
605 - improved audio grabbing. The 'grab' command of para_audiod
606 has its own set of command line options. Read the output of
607 "para_audioc help grab" for more info.
608 - oggdec: configurable input prebuffer size.
609 - the new error subsystem gives better error diagnostics
610 and reduces code size.
611
612
613 -----------------------------------------
614 0.2.8 (2006-01-02) "dynamic accumulation"
615 -----------------------------------------
616
617 The new modular filter design and the para_play-hangs bugfix.
618
619 - new executable: para_filter. It combines para_mp3dec,
620 para_oggdec and para_compress. It also adds a further filter
621 type, wav, that just inserts a wave header at the desired point
622 of the filter chain. All 'piping' is done in-memory (i.e. no
623 read/write operations are used).
624 - para_play: fix a stupid bug that caused it to hang under
625 certain circumstances.
626
627
628 -------------------------------------------
629 0.2.7 (2006-12-27) "transparent invariance"
630 -------------------------------------------
631
632 Not many user-visible changes but a fair amount of internal improvements.
633
634
635 - The http sender buffers data if it can not be sent
636 out immediately (because the socket is not writable). This
637 should prevent para_server from shutting down the connection
638 too early on a loaded network.
639 - para_play also prebuffers data if it is told to start at a
640 future time by the --start_time option.
641 - The return of para_recv: It combines para_ortp_recv and
642 para_http_recv. Use the --receiver option to switch between
643 the two. para_recv builds without libortp, but contains
644 only the http receiver in this case.
645 - update to ortp 0.8.1. As this ortp release contains incompatible
646 changes, para_recv-0.2.7 won't link against older ortp libs.
647 - improved ortp timings.
648 - use of gcc-extensions that #define away for non-gcc and
649 gcc < 3.0.
650
651
652 -------------------------------------------
653 0.2.6 (2005-10-29) "recursive compensation"
654 -------------------------------------------
655
656 Transparent session encryption (uses openssl's Alleged RC4 cipher),
657 the internal find command and several other improvements and cleanups.
658
659 - Encrypt the session if encryption is requested by the client
660 (default for para_client 0.2.6). This is backwards
661 compatible, so older clients can still connect to para_server
662 0.2.6. Use the new client option --plain to request an
663 uncrypted session (off by default, must be set to on in
664 order to connect to para_server 0.2.x with 0 <= x <= 5).
665 - para_server uses an internal function to locate audio files
666 rather than calling find(1). The server option
667 --mysql_audio_file_dir replaces --mysql_find_cmd.
668 - documentation update
669 - man pages
670 - header file cleanup
671 - para_client code cleanup
672 - para_gui: faster display of output of display commands
673
674
675 ------------------------------------------
676 0.2.5 (2005-10-13) "aggressive resolution"
677 ------------------------------------------
678
679 This release adds internal senders, i.e. no more external programs are
680 spawned for sending out the audio data. There are two different senders
681 available: The http sender and the ortp sender (former para_send which
682 is no longer needed).
683
684 The new sender code has a plugin-like design so it can be easily
685 extended should there be be any future need for supporting another
686 network streaming protocol. All senders are completely independent of
687 each other. In particular, the http and the ortp sender can operate
688 in parallel.
689
690 - new server command: sender to control senders at runtime.
691 Read the output of "para_server -h" and "para_client help
692 sender" for more information.
693 - para_recv renamed to para_ortp_recv
694 - new executable: para_http_recv, a simple command line
695 http receiver.
696 - major afs/mp3/ogg code simplifications due to internal
697 senders.
698 - ogg timing improvements
699 - fix several minor memory leaks (found by valgrind)
700 - empty stream definitions work again
701 - com_ne(): ignore errors on remove
702 - audiod: fix segfault on server restart
703
704
705 ---------------------------------------
706 0.2.4 (2005-09-21) "toxic anticipation"
707 ---------------------------------------
708
709 Several small improvements, fixes and the new grab command.
710
711 - audiod:
712 - new command: "grab" to grab the output of the stream reader
713 or any filters. Read the output of "para_audioc help grab"
714 for more information.
715 - fix memory leak
716 - code cleanup
717 - audioc: new command line option: --bufsize to specify a
718 buffer size different from the default size 8192.
719 - improved error diagnostics for para_play.
720 - new configure option: --enable-ssldir so search for openssl in
721 non-standard places
722 - sdl_gui: Make it look nice again for 1024x768
723 - server: report total size of memory allocated with sbrk by malloc,
724 new command line option: --announce_time
725
726
727 -----------------------------------------
728 0.2.3 (2005-09-01) "hydrophilic movement"
729 -----------------------------------------
730
731 Two new executables and major feature enhancements.
732
733 - audiod filters: It is now possible to specify arbitrary many
734 (including none) filters for each supported audio
735 format. This can be used e.g. for normalizing volume,
736 transforming or grabbing the audio stream, or for using
737 visualizers. Read the output of "para_audiod -h" for the
738 syntax of the new --filter_cmd option.
739 - new executable: para_play, a tiny alsa player. It
740 can play wave files or raw pcm (16 bit little endian)
741 from stdin.
742 - new executable: para_compress, a dynamic range compressor
743 intended to keep audio output at a consistent volume. Derived
744 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
745 - audiod: New option: --stream_delay. This can be used in
746 a local network to syncronize the audio output of all
747 clients that play the same stream.
748
749
750 ------------------------------------------
751 0.2.2 (2005-08-19) "tangential excitation"
752 ------------------------------------------
753
754 Mostly internal changes in this release, but also some new commands
755 for the mysql database tool.
756
757 - cleanup exec.c, fix para_exec bug
758 - compile time loglevel (log messages below the given level
759 won't be compiled in, which reduces the size of the
760 resulting binaries)
761 - new log macros that shorten the size of the source code.
762 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
763 to send only zeros. With this workaround, para_audioc works
764 again.
765 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
766 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
767 (new entry), "snp" (set numplayed). Read the manual for more
768 information.
769
770
771 ---------------------------------------
772 0.2.1 (2005-08-15) "surreal experience"
773 ---------------------------------------
774
775 Here comes paraslash-0.2.1. It contains a couple of new features and,
776 surprise, only minor bug fixes.
777
778 - kill noisy mp3 debug message
779 - cleanup of the build system
780 - para_server and para_client directly use the crypto routines
781 of the openssl library rather than invoking the openssl command
782 line utitlity
783 - server/audiod: new option --user to switch to the given user
784 when invoked as root. Read the output of "para_server -h" for
785 more information.
786 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
787 status. Default: "para_audioc stat"
788 - sdl_gui: new option --pic_cmd to be used to download the picture.
789 Default: "para_client pic"
790 - audiod: 5 slots ought to be enough for everybody
791 - audiod: new status item: Uptime, kill hup command
792
793
794
795 ------------------------------------------
796 0.2.0 (2005-08-06) "distributed diffusion"
797 ------------------------------------------
798
799 After several month of increased development activity, paraslash-0.2.0
800 has arrived. It contains many new features and is much more
801 self-contained than the old 0.1.x series. Enjoy!
802
803
804 - para_server: fix hang on song change and crash on sighup.
805 Speed up mysql queries. The DIR_LIKE macro is gone.
806 - new executables: para_audiod, the local audio daemon that
807 starts playback (uses SCM_CREDENTIALS socket magic) and
808 para_audioc, the corresponding client.
809 - new executables: para_mp3dec/para_oggdec, two really teensy
810 decoders. para_mp3dec is based on libmad, para_oggdec requires
811 libvorbisfile.
812 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
813 they are now called para_send and para_recv respectively.
814 - documentation updates
815 - para_gui is themable. For now there is the default theme that
816 looks as before and the simple theme: blue and easy.
817 - gui: audio streaming is now handled by audiod. Time display shows
818 playback time rather than streaming time
819 - slider: update to libzmw-0.2.0
820 - para_krell: fix crash on server shutdown
821 - switch from gzip to bzip2
822
823
824 ----------------------------------------
825 0.1.7 (2005-04-18) "melting penetration"
826 ----------------------------------------
827
828 The main change in this release is clearly the oggvorbis rewrite,
829 but there are also lots of smaller changes. If you intend to use both
830 the mp3 and the ogg plugin, it is recommended to use software mixing,
831 e.g. the dmix plugin which is provided by ALSA.
832
833 - new executables: para_ovsend and para_ovrecv for sending/receiving
834 oggvorbis files via rtp. Requires the open rtp library. Get it at
835 http://www.linphone.org/ortp/
836 - rewrite of the ogg_vorbis core code
837 - configure detects libzmw and, if detected, includes
838 para_slider to the list of binaries to be built by make
839 - server stream writers read from their associated fifo rather
840 than from stdin
841 - slider: two new sliders, lastplayed and numplayed
842 - fix nasty double free bug which caused random segfaults in case of
843 mp3 files with invalid header information
844 - gui: new command line option: --stream_timeout=seconds to
845 deactivate a slot if it is idle for that many seconds (default=`5')
846 - diffstats
847
848
849 ---------------------------------------
850 0.1.6 (2005-03-05) "asymptotic balance"
851 ---------------------------------------
852
853 Only little user-visible changes in this release. Mainly bugfixes and
854 core code cleanup. This is probably the most stable version ever if you
855 stick to mp3...
856
857 - fix several memory leaks
858 - rename default name of mysql database from "music" to "paraslash".
859 Use para_server's --mysql_database option if you do not want to
860 rename your old database.
861 - rework ogg vorbis code
862 - make update command work on mysql servers with LOCAL_INFILE
863 disabled
864 - gui: improved stream I/O (slots)
865 - simplified audio format API
866 - para_pob_ogg is gone
867
868 ------------------------------------
869 0.1.5 (2004-12-31) "opaque eternity"
870 ------------------------------------
871
872 Let's slide gently into the new year.
873
874 - new: para_slider (not built automatically, type "make
875 para_slider" to build). A toy for those who always felt that
876 creating stream definitions is difficult. See screenshots,
877 README and FEATURES for more info.
878 - improved signal handling. Fixes server segfault on SIGHUP
879 for linux kernels newer than Aug 24 2004 and makes para_gui
880 race-free.
881 - reload database tool on SIGHUP
882 - improved help message for sl
883 - do not log "broken pipe" messages as errors. They are
884 perfectly ok.
885 - fix wrong error message on permission errors
886
887 -----------------------------------------
888 0.1.4 (2004-12-19) "tunneling transition"
889 -----------------------------------------
890
891 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
892 Hopefully, most of them got wiped out with this release. Some
893 enhancements went also in.
894
895 - improved error diagnostics for all commands
896 - stradd/picadd: overwrite previous contents if entry already
897 exists, rather than returning errors
898 - stradd: use current stream if invoked without args
899 - faster (and hopefully more stable) ogg-vorbis handling
900 - para_krell: reap children to avoid zombie-flooding in case
901 no server is running
902 - si: report also server pid
903 - server: don't busy-loop if dbtool reports only invalid files.
904 - gui: CTRL+C works again, fix stream_read command line option
905 - fix pic_add, hist
906 - fix mysql dbtool startup in case no database exists
907 - many small fixes and cleanups
908
909 ---------------------------------------
910 0.1.3: (2004-12-10) "vanishing inertia"
911 ---------------------------------------
912
913 Starting from this release, the database tools are integrated in the
914 server binary. This decreases server startup time, reduces code size
915 and speeds up database commands. However, the layout of the underlying
916 mysql database changed only slightly and 0.1.3 should be backwards
917 compatible in that respect.
918
919 Visible changes:
920
921 - If mysql is not detected at compile time, or fails to init
922 at runtime, fall back to the dopey database tool which should
923 always work.
924 - para_dbtool and dbtool.conf are gone. All mysql specific
925 options are read from server.conf and are prefixed by 'mysql_'.
926 - new command: cdt (change database tool)
927 - new command line option: dbtool (choose startup database tool)
928 - The name of current stream is now stored in the database,
929 so paraslash remembers its current stream when restarted.
930 - new command: csp (change stream and play)
931 - para_gui also reports current database tool and server uptime
932
933
934 -------------------------------------------
935 0.1.2: (2004-11-28) "spherical fluctuation"
936 -------------------------------------------
937
938 Point release before the big dbtool changes go in.
939
940 - dbtool: rename ca to cam (copy all meta data). It now also
941 copies numplayed and lastplayed time as well as the picture
942 id.
943 - fix endless-loop-bug caused by mp3 files with invalid header
944
945 -----------------------------------------
946 0.1.1: (2004-11-05) "floating atmosphere"
947 -----------------------------------------
948
949 - gkrellm plugin
950 - new dbtool command: mbox. Browse your sound-file collection
951 with your favorite mail reader.
952 - several small fixes
953
954 -------------------------------------
955 0.1.0: (2204-10-22) "rotating cortex"
956 -------------------------------------
957
958 - fix logging bug for loglevel > VERBOSE
959 - fix skip command
960 - correct timings for vbr mp3s
961 - modular audio format support
962 - ogg-vorbis support (experimental)
963 - new server option: autoplay
964
965 -----------------------------------------
966 0.0.99: (2004-07-25) "harmonic deviation"
967 -----------------------------------------
968
969 - rename projectname from icc to paraslash (play, archive, rate
970 and stream large audio sets happily)
971 - paraslash is no longer restricted to one particular audio
972 streaming software
973 - new dbtool commands (stradd, strq, strdel) for easy stream
974 managment w/o configuration file. That obsoletes stream_defs
975 file/config option for dbtool.
976 - picadd accepts jpeg data from stdin
977 - new server commands: ps (select previous stream), sc (song change)
978 - new default pictures for sdl_gui
979 - gui: new key_map option for binding commands and internal
980 functions to arbitrary keys, nice help screen, rip out
981 soundcard/linux specific stuff, avoid noise artefacts while jumping,
982 show silly logo on startup
983 - new executables: para_fade for fading volume, para_dbadm for
984 manipulating attributes
985 - cdb adds _all_ tables to mysql database
986 - revised and beautified documentation
987 - sample dbtool rewritten in C
988 - autoconf
989
990 ---------------------------------------------
991 0.0.98: (2003-12-26) "incremental smoothness"
992 ---------------------------------------------
993
994 - kick icecast in favour of poc. That removes some races and reduces
995 core code considerably.
996 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
997 give finer info on afs' status.
998 - gui can start decoder (see config options). Further new gui
999 commands: refresh (^L), jmp (F1-F10)
1000 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1001 terminates gui. This fixes dead instances consuming memory
1002 continuously.
1003 - new dbtool command: verb for sending verbatim sql queries.
1004 - fix pid_list races (by removing pid_list)
1005 - codename funnies
1006
1007 --------------------
1008 0.0.97: (2003-10-26)
1009 --------------------
1010
1011 - installation prefix now defaults to /usr/local
1012 - new commands for gui: snozze, sleep and reread config
1013 - config file for gui and sdl_gui
1014 - fix problems with filenames containing funny characters
1015 (reported by Thomas Forell)
1016 - improved signal handling for gui, now it rereads conf on SIGHUP
1017 - new dbtool command: cdb (create database)
1018 - switch from argtable to gengetopt
1019 - major code cleanup and speed improvements
1020 - fix several potential buffer overflows
1021 - many small fixes and cleanups
1022
1023 -------------------
1024 0.0.96 (2003-08-30)
1025 -------------------
1026
1027 - easy stream_defs syntax
1028 - sdl_gui can display images associated to the file being played
1029 - Major feature enhancements for icc_gui including dynamic text
1030 placement and the top/bottom window design
1031 - vrfy/clean now also checks for NULL values in attributes as
1032 well as for invalid picture pointers
1033 - fix long outstanding case sensitivity bug
1034 - many small fixes and cleanups
1035
1036 -------------------
1037 0.0.95 (2003-06-29)
1038 -------------------
1039
1040 - sdl gui runs much faster
1041 - new dbtool command: ca (copy attributes)
1042 - count and display number of times the song has been played
1043 - new feature: scoring
1044 - command line options for sdl_gui
1045 - simpler syntax of streams file
1046 - decrease network traffic of stat
1047 - fix zombie bug
1048 - many small fixes and cleanups
1049
1050 -------------------
1051 0.0.94 (2003-05-04)
1052 -------------------
1053
1054 - new server command: ns (next stream)
1055 - new icc_gui command: c (change stream)
1056 - internal mp3info
1057 - stat shows also id3 tag info
1058 - new sdl based gui
1059 - log flodding bug fixed
1060 - many small fixes and cleanups
1061
1062 -------------------
1063 0.0.93 (2003-03-28)
1064 -------------------
1065
1066 - colors for icc_gui
1067 - icc_gui sets volume directly (linux only)
1068 - proper locking that fixes some races
