Merge branch 't/utf8'
[paraslash.git] / NEWS
1 ------------------------------------------
2 0.?.? (to be announced) "spectral gravity"
3 ------------------------------------------
4
5 - UTF8 support for para_gui and the mp3 audio format handler.
6
7 -----------------------------------------
8 0.4.12 (2012-12-20) "volatile relativity"
9 -----------------------------------------
10 The new command line player, the resample filter, ALSA support for
11 para_fade, and the improved build system are the highlights of this
12 release which probably marks the end of the 0.4.x series.
13
14 - The afh receiver and the para_play executable.
15 - The resample filter: A sample rate converter based on
16 libsamplerate.
17 - The "versions" directory has been removed from the master
18 branch. The tarballs of the old releases are now available
19 in the new "releases" branch.
20 - Overhaul of the build system: All generated files are now
21 written to the "build" directory.
22 - The modular mixer API and the alsa mixer.
23 - Minor fixes for the osx writer.
24
25 --------------------------------------
26 0.4.11 (2012-07-20) "mutual diversity"
27 --------------------------------------
28
29 The major feature in this release is the new sideband API for
30 client-server communication. This API will be used exclusively starting
31 with 0.5.0, which breaks backward compatibility but allows to get rid
32 of quite some compatibility code. Other noteworthy changes include
33 decoder latency improvements and a long-standing bug fix for the
34 ALSA writer.
35
36 - Sideband connections: If both para_server and para_client
37 support this feature, data is sent as a multiplexed stream.
38 - The --no_default_filters option of para_filter has been
39 removed.
40 - Several fixes and latency improvements to various decoders.
41 - The ALSA writer now limits the prebuffer time to 500ms.
42 - Documentation improvements.
43 - Overhaul of the command_util.sh script.
44 - Fixes for some minor problems found by the clang analyzer.
45 - Compiles (almost) without warnings on gcc-3.
46 - Robustness improvements of the buffer tree code.
47
48 ------------------------------------------
49 0.4.10 (2012-03-30) "heterogeneous vacuum"
50 ------------------------------------------
51
52 Nothing earth-shaking in this release, but quite a few usability
53 improvements and the usual mix of cleanups and fixes.
54
55 - The --no_default_filters option of para_filter has been
56 deprecated. It still works but has no effect and will be
57 removed in the next version.
58 - para_gui now prints also the stderr output of the executing
59 command in the bottom window.
60 - Cleanup and consolidation of the various wrappers for
61 write(), writev(), send() and friends.
62 - The obscure error messages on mmap() failures have been
63 replaced by meaningful messages. This affects mainly
64 para_afh.
65 - para_audioc: Cleanups and memory leak fixes.
66 - Test 0004-server no longer fails if para_server is not
67 being built.
68 - New configure options: --with-id3tag-{headers,libs}.
69
70 -------------------------------------
71 0.4.9 (2011-12-06) "hybrid causality"
72 -------------------------------------
73
74 Support for another audio format, interactive mode for para_client
75 and para_audiod and many small improvements/fixes all over the place.
76
77 - Support for flac, the free lossless audio codec.
78 - Fix for an endless loop in the mp3 decoder for certain
79 (corrupt) mp3 files.
80 - When executed without specifying a command, para_client
81 and para_audioc start an interactive shell (requires
82 libreadline being installed). The interactive mode offers
83 full tab completion and command line history.
84 - autogen.sh now detects a distcc setup and adjusts the
85 parameter for the -j option of make accordingly.
86 - Shared memory areas are no longer restricted to 64K. We now
87 detect the maximal size of a shared memory area at runtime.
88 - cleanup of the internal uptime API.
89 - para_server prefaults the mmapped audio file to avoid
90 delays on slow media.
91 - A new test for the test-suite that exercises the
92 communication between para_server and para_audiod.
93 - The alsa writer eats up less CPU cycles when configured to
94 use the DMIX plugin.
95 - Simplified and unified receiver code.
96 - Makefile cleanups.
97 - Commands which print a list of matching audio files now
98 emit a meaningful error message if no audio file matched the
99 given pattern(s).
100
101 --------------------------------------
102 0.4.8 (2011-08-19) "nested assignment"
103 --------------------------------------
104
105 Gcrypt support, the overhauled osx writer and regex format specifiers
106 are the highlights of this release.
107
108 - support for libgcrypt as a drop-in replacement for openssl.
109 Run configure --enable-cryptolib=gcrypt to link against
110 libgcrypt. The two crypto implementations are compatible to
111 each other, i.e. a para_client executable linked against
112 gcrypt can connect to para_server linked against libssl
113 and vice versa.
114 - Rewrite of the osx writer (output plugin for Mac OS).
115 - audiod: The format specifier for receivers, filters and
116 writers is now treated as a regular expression. This allows
117 to replace 5 lines in the config file (one for each audio
118 format) by one single line. See the manual for details.
119 - The *.cmdline.[ch] files are no longer contained in the released
120 tarballs. This reduces the size of the tarballs but requires
121 gengetopt to build the tarball.
122 - Compiles cleanly also with llvm/clang.
123 - Corrupt mp3 files are handled more gracefully.
124 - The alsa writer uses poll fds instead of computing timeouts.
125 - Cleanup of the generic writer API.
126 - sched: Optimized zero timeouts.
127 - vss timeout cleanups.
128 - oggdec fixes and improvements.
129
130 --------------------------------------
131 0.4.7 (2011-06-01) "infinite rollback"
132 --------------------------------------
133
134 The new ao writer, support for ssh RSA keys and a couple of other
135 enhancements.
136
137 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
138 platforms through the libao audio library.
139 - Support for RSA keys generated with ssh-keygen.
140 - configure: improved options for ogg/vorbis/speex.
141 - The git version reported by --version always matches HEAD.
142 - The autogen script detects the number of processors and
143 runs a parallel make if possible.
144 - Major cleanup of the crypto API.
145 - Documentation updates.
146
147 ------------------------------------------
148 0.4.6 (2011-03-31) "deterministic entropy"
149 ------------------------------------------
150
151 Lots of ogg/vorbis improvements, the new test suite, enhancements
152 for para_gui and a fair amount of other bug fixes.
153
154 - For DCCP/OGG streams the audio file header is only sent once
155 at the beginning of the stream rather than periodically
156 every five seconds. This reduces network traffic and the
157 FEC group size.
158 - The vorbis comment header is replaced by an empty dummy header
159 before the header is sent over the network. This also results in
160 less network traffic and smaller FEC groups.
161 - The new "test" make target allows to perform some sanity checks prior
162 to installing the package.
163 - ogg timing fixes and performance improvements
164 - Scheduler improvements
165 - Proper exit codes for para_write
166 - para_gui: New option --theme to select a startup theme. Several
167 other improvements and fixes.
168 - aacdec error message cleanups
169 - simplified color error handling
170
171 --------------------------------------------
172 0.4.5 (2010-12-17) "symmetric randomization"
173 --------------------------------------------
174
175 Bug fixes, internal cleanups and variable-sized FEC slices.
176
177 - Contains a fix for an invalid-free-bug in the ogg audio format
178 handler code.
179 - Switching off the DCCP sender works again.
180 - para_audiod handles crashes of para_server more robustly.
181 - Internal scheduler and writer cleanups.
182 - Reduced latency due to variable-sized FEC slices.
183 - Improved documentation and error diagnostics.
184 - The build of para_server is now optional, allowing the build
185 to succeed in case libosl is not installed.
186
187 ------------------------------------------
188 0.4.4 (2010-08-06) "persistent regularity"
189 ------------------------------------------
190
191 Support for yet another audio format, para_write improvements and
192 bug fixes.
193
194 - Support for the speex codec.
195 - Support for sample formats other than 16 bit little endian.
196 - error2.h is now created by a perl script which speeds up configure
197 considerably.
198 - Fix a bug in the aac decoder which could lead to segfaults in
199 para_filter/para_audiod.
200 - Fixes for autoconf-2.66.
201
202 ----------------------------------------
203 0.4.3 (2010-07-05) "imaginary radiation"
204 ----------------------------------------
205
206 Many improvements for the DCCP and the UDP transport, the new user
207 manual and the usual mix of bug fixes and internal improvements.
208
209 - FEC support for the DCCP sender (Gerrit Renker). The new
210 --dccp_max_slice_size, --dccp_data_slices_per_group and
211 --dccp_slices_per_group options can be used to set the FEC
212 parameters for the DCCP transport.
213 - DNS lookups for UDP targets (Gerrit Renker).
214 - The new user manual replaces the README, README.afs, REQUIREMENTS
215 and INSTALL documents.
216 - Fix an end-of-file detection bug in the oggdec filter.
217 - The new nonblock API.
218 - Both options of the oggdec filter have been removed.
219 - New debug mode for the internal scheduler.
220
221 ------------------------------------------
222 0.4.2 (2010-04-23) "associative expansion"
223 ------------------------------------------
224
225 It's been some time since the last release, but finally here is
226 paraslash-0.4.2. The bulk of the changes comes from the new buffer
227 tree API, but there are changes all over the tree. Mainly performance
228 and usability improvements, but also quite some bug fixes.
229
230 - The new buffer tree API.
231 - DCCP: Support for CCID negotiation (Gerrit Renker).
232 - UDP robustness fixes.
233 - The --bufsize option for mp3dec is gone as it no longer makes sense
234 for the new buffer tree API.
235 - Fix audible buffer underruns for wma streams.
236 - The alsa writer no longer prints meaningless underrun durations.
237 - audiod: Defaults work also for udp streams. If no filter is
238 given for an audio format that is received via upd, fecdec is
239 automatically added as the first filter (along with the decoder).
240
241 ---------------------------------------
242 0.4.1 (2009-12-22) "concurrent horizon"
243 ---------------------------------------
244
245 Support for another audio format, minor feature enhancements and lots of bug
246 fixes. All fixes that have been accumulated in the maint branch (in particular
247 those mentionened in the 0.3.6 release notes) appear in this release as well.
248
249 - wma support.
250 - new afh option: --human to activate human-readable output.
251 - new server/audiod option: --log-timing to print timing information.
252 - build system improvements.
253 - source code documentation updates.
254
255 -------------------------------------
256 0.3.6 (2009-12-07) "cubic continuity"
257 -------------------------------------
258
259 Quite a few bugs have been found and fixed since 0.3.5, so here's
260 another 0.3.x release. No new features.
261
262 - Always check return value of malloc().
263 - ogg vorbis/FEC: Do not write garbage after the audio file header.
264 - exit if root privileges could not be dropped.
265 - FEC: Fix computation of extra slices.
266 - oss: Fix check for empty input buffer.
267 - Avoid buffer underruns due to filter chain output buffer constraints.
268 - server: Fix assignment of afs_pid.
269 - Don't panic if the afs database contains unknown audio formats.
270 - http/dccp: Do not send the audio file header twice.
271 - FEC: Timing improvements.
272
273 ----------------------------------------------
274 0.4.0 (2009-11-10) "simultaneous independence"
275 ----------------------------------------------
276
277 Two significant changes which require the new version number: The
278 improved authentication dialog and the fact that the database code
279 has been moved to a library, libosl. To use the new version, you have
280 to generate new RSA keys, see INSTALL for details. A shell script is
281 provided for conversion of the 0.3 database to the new 0.4 format.
282
283 - stronger crypto for client authentication
284 - the database code has been moved to a library
285 - improved status item handling
286 - cleanup of the build system
287 - The "-V" option now also prints the git version
288 - the new parser-friendly listing mode for the ls and stat commands
289 - mandatory rc4 encryption
290 - major audio format handler cleanups
291 - (id3,...) tags are no longer stored as a combined string in the database
292 - new mood methods: artist_matches, title_matches, comment_matches,
293 album_matches, year_maches, year.
294
295 --------------------------------------------
296 0.3.5 (2009-09-21) "symplectic separability"
297 --------------------------------------------
298
299 Full client support for *BSD Unixes, complete re-write of the ogg
300 vorbis audio format handler, various improvements all over the place
301 and the usual mix of bugfixes. This release marks the end of the 0.3
302 series if no serious problems show up.
303
304 - the new oss writer (supported on *BSD and Linux)
305 - rewrite of the ogg vorbis audio format handler. It's
306 recommended to replace the chunk tables of existing ogg
307 vorbis files in the afs database by re-adding these files
308 with "add -f".
309 - support for netmask subsets (Gerrit Renker)
310 - the new prebuffer filter
311 - improved signal handling
312 - variable fec output buffer size
313 - improved FEC timing fixes audible buffer underruns in UDP mode
314 - --log_color actually works
315 - new ls option: -d (print dates as seconds after the epoch)
316 - update to gengetopt 2.22.2
317 - support for RSA keys of size > 512 bits
318 - new option "mixer_channel" for para_fade
319
320 -----------------------------------------
321 0.3.4 (2009-05-07) "elliptic inheritance"
322 -----------------------------------------
323
324 The new udp sender, forward error correction, colored logs and various
325 other improvements. As the udp sender does not depend on any special
326 libraries, it is built unconditionally.
327
328 - The udp sender replaces the ortp sender. The new code uses forward
329 error correction to protect against packet losses. Many thanks to
330 Gerrit Renker for providing ipv6 support.
331 - The default port for udp streaming now defaults to 8000, like
332 for the http and the dccp senders/receivers.
333 - Loglevels are now specified as symbolic names, e.g.
334 "--loglevel info".
335 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
336 - para_server/para_audiod: Color support for log messages.
337 - new options for mp3dec: --ignore-crc, --bufsize
338 - new audiod option: --config-file.
339 - gengetopt cleanups.
340 - Improved help/man pages: The documentation of para_audiod,
341 para_recv, para_filter and para_write now also contains
342 all options of the available receivers/filters/writers. The
343 man page of para_fade contains a description of the different
344 modes of operation.
345 - More source code documentation.
346 - vss timing fixes.
347
348 --------------------------------------------
349 0.3.3 (2008-12-01) "axiomatic perspectivity"
350 --------------------------------------------
351
352 Internal code cleanups, bug fixes, improved tag handling and the new
353 amplification filter.
354
355 - para_server uses the generic scheduling code.
356 - overhaul of the virtual streaming system.
357 - mp3: id3 version 2 support via libid3tag (optional)
358 - ogg: vorbis comment support.
359 - aac meta info support.
360 - mp3 audio format handler cleanups.
361 - new filter: "amp" to amplify the amplitude of the audio stream
362 - new status item/database entry: amplification. It is
363 used by the amp filter to pre-amplify the audio stream.
364 - fix a close-without-open bug in para_write.
365 - fix a bug in com_init() which was introduced in 0.3.2.
366 - better error diagnostics for para_client.
367
368 -----------------------------------------
369 0.3.2 (2008-04-11) "probabilistic parity"
370 -----------------------------------------
371
372 The new para_afh executable, scheduling and documentation improvements.
373
374 - new ls option: -lc (list chunk table)
375 - new executable: para_afh, the stand-alone audio file handler tool
376 - afs commands can send output more than SHMMAX (32MB on Linux). This
377 also reduces the memory usage of commands that produce large amounts
378 of output.
379 - major scheduler and audiod cleanups.
380 - more detailed and much nicer man pages.
381
382 ---------------------------------------
383 0.3.1 (2008-02-23) "liquid interaction"
384 ---------------------------------------
385
386 A mix of cleanups, bug fixes, improvements, and some new features. No
387 significant changes to the new database (osl) code, which is generally
388 a good sign.
389
390 - Share some similar/duplicate code between the http and the
391 dccp sender.
392 - Generic access control lists for paraslash senders.
393 - dccp sender: Access control lists, connection limiting and support
394 for the allow,deny,on,off,help sender commands.
395 - The default dccp port changed from 5001 to 8000 (suggested by
396 Gerrit Renker).
397 - para_server starts even if not all public keys could be loaded.
398 - Audiod performance improvements.
399 - fix a bug in the "off" command of the http sender.
400 - fix some fd and memory leaks.
401 - Update to gengetopt-2.22.
402
403 -------------------------------------
404 0.3.0 (2008-01-12) "solar saturation"
405 -------------------------------------
406
407 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
408
409
410 Usually one might expect lots of new features AND a big increase in size
411 for a major release like this.
412
413 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
414 ever. The decrease in size is mostly due to the removal of some
415 graphical tools (which were only quick hacks anyway). But also the
416 fact that the mysql code is gone cuts down the size a bit.
417
418 Being independent of mysql comes at a cost: The fact that paraslash
419 now contains its own database (the object storage layer, osl) increases
420 the (stripped) binary size of para_server by ~50K on i386.
421
422 - no more restrictions on unique basenames.
423 - independent of mysql: The new self-contained object
424 storage layer (osl) replaces the mysql database.
425 - New executable para_fsck: Check integrity of osl tables.
426 - Lyrics support.
427 - Reliable audio file move/rename detection.
428 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
429 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
430 Solaris (sparc64).
431 - the new osl-based audio file selector (afs) replaces the random,
432 the playlist and the mysql selector of paraslash-0.2.x.
433 - IPv6 support (thanks to Gerrit Renker).
434 - paraslash-0.2.x streams are now called "moods". Writing
435 0.3.x-mood definitions should be both easier and more
436 powerful than writing 0.2.x-stream definitions.
437 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
438 been removed. The world is a better place without them. However,
439 para_gui is still there.
440 - afs tracks audio file selection also in playlist mode.
441 - few easy-to-use afs commands replace the many not-so-easy-to-use
442 mysql commands (and are available also in playlist mode).
443 - Improved error subsystem.
444 - The earth-shaking new logo.
445
446 -----------------------------------------
447 0.2.17 (2007-11-20) "isotropic threshold"
448 -----------------------------------------
449
450 Mainly bugfixes and cleanups in this version which marks the end of
451 the 0.2.x series if no serious bugs show up after the release.
452
453 - mysql_selector: fix a locking bug.
454 - universal chunk queueing.
455 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
456 to Gerrit Renker).
457 - be more carful wrt. signed vs. unsigned argument passing.
458 - cleanup error.h and fix some references to invalid error
459 codes.
460 - update to gengetopt-2.21.
461 - update to ortp-0.13.1.
462 - autoconf: extend checks for headers, library functions and
463 compiler characteristics.
464 - Fix streaming of large mp3 files.
465 - Fix an off-by-one bug in playlist handling.
466
467 --------------------------------------
468 0.2.16 (2007-04-05) "neural discharge"
469 --------------------------------------
470
471 The main change in this release is the major audio format handler
472 cleanup which removes some similar/duplicate code and makes it easier
473 to implement plugins for other audio formats. Of course, the usual mix
474 of other improvements/changes/bugfixes also made it into the release.
475
476 - simplified audio format handlers (most of the handling functions
477 were moved one layer up to the virtual streaming system).
478 - para_server uses mmap to read audio files
479 - repositioning of mp3 streams is much faster, in particular for
480 jumping near the end of large mp3 files.
481 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
482 and AFS_WRITE.
483 - fix a bug in para_filter that caused decoding of aac files
484 to start only after a few seconds.
485 - fix osx_writer hangs
486 - simplified dccp code (thanks to Gerrit Renker)
487 - the compress filter works also on big endian systems (ppc)
488
489 -----------------------------------------
490 0.2.15 (2007-02-16) "inductive resonance"
491 -----------------------------------------
492
493 Minor improvements, more documentation and a bunch of bug fixes.
494
495 - para_server: The server.users file is only read once on server
496 startup rather than for each connection
497 - mp3dec: Fix decoding of corrupt mp3 files
498 - afs (audio file sender) is now called vss (virtual streaming
499 system). Consequently, the permission flags specified in
500 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
501 become VSS_READ and VSS_WRITE respectively.
502 - para_audiod/para_filter: Fix a bug that caused the last chunk
503 of audio data not being written under certain circumstances
504 - audiod: compute the difference of server time and local time
505 correctly
506 - para_server/para_audiod: Fix some memory leaks
507 - documentation improvements
508 - configure.ac: fix checks for para_krell
509 - new man pages
510
511 -------------------------------------------
512 0.2.14 (2006-10-15) "transient singularity"
513 -------------------------------------------
514
515 The only major enhancement of this version is the osx writer which completes
516 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
517 until now for reasons beyond the scope of this changelog entry.
518
519 - new output plugin for Mac Os: the osx writer
520 - rename configure command line options from --enable-xxx-headers to
521 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
522 - configure: new command line options: --with-mad-headers,
523 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
524 - some robustness fixes
525 - dymamic audio format recognition for audiod
526 - para_server: new command line option: --autoplay_delay
527 - para_audiod: new command line option: --clock_diff_count
528
529 ---------------------------------------
530 0.2.13 (2006-07-14) "sonic convolution"
531 ---------------------------------------
532
533 A bunch of new features and core changes.
534
535 - the new paraslash scheduler, short and sweet.
536 - Support for m4a/mp4 files via the new aac audio format
537 handler/filter (requires libfaad).
538 - each writer has its own command line parser, just like
539 para_recv and para_filter.
540 - para_client and para_audioc use the error subsystem
541 - writers are integrated in para_audiod (currently linux-only)
542 - para_client is integrated in para_audiod
543 - random/playlist selector: improved info strings
544 - new audiod commands: tasks, kill
545 - update to libortp-0.10.1
546 - para_fade: wake time defaults to 8 hours from now
547 - update to autoconf-2.60
548
549 ------------------------------------------
550 0.2.12 (2006-05-12) "oriented abstraction"
551 ------------------------------------------
552
553 Many user-visible changes in this release and lots of new
554 features:
555
556
557 - the new optional dccp sender/receiver. It uses the datagram
558 congestion control protocol. You'll need a fairly new kernel
559 for this.
560 - paraslash works on Mac OS X (thanks to Gerd Becker)
561 - para_play renamed to para_write
562 - modular output plugin design (writers) for para_write
563 - new file_writer output plugin for para_write
564 - compress filter speed improvements
565 - update to libortp-0.9.1
566 - update to gengetopt-2.17rc
567 - para_client no longer depends on libreadline (as the
568 code for the interactive mode was removed).
569 - gcc-2-95 is no longer a supported compiler. It may still
570 work, but it gets no more testing.
571 - the tarball no longer contains the screenshot images which
572 reduces its size quite a bit.
573 - configure: new command line options: --enable-mysql-headers
574 and --enable-mysql-libs
575
576 ------------------------------------
577 0.2.11 (2006-03-11) "atomic duality"
578 ------------------------------------
579
580 Here it is, the first paraslash release developed with git. There
581 are fairly many user-visible changes in this release. As two out of
582 the three "database tools" of paraslash don't use a database at all,
583 they are now called "audio file selectors" instead.
584
585
586 - the cdt command (change database tool) becomes chs (change
587 selector)
588 - no more colon separators: The syntax of some options of
589 para_audiod and para_filter have changed. Use --help for
590 more info (and some examples).
591 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
592 - switch from cvs to git (should've done that earlier)
593 - the new ipc subsystem
594 - new audio file selector: playlist
595 - para_server: the dopey selector is now called "random",
596 and is the default selector. Use the --selector option to
597 choose another selector at startup, or the chs command to
598 change the selector at runtime.
599 - X86_64 fixes (thanks to Steffen Klassert)
600 - para_play fixes
601
602 --------------------------------------
603 0.2.10 (2006-02-17) "cyclic attractor"
604 --------------------------------------
605
606 Huge documentation update, a scrollable window for para_gui, ortp
607 improvements, and of course many small fixes not mentioned here.
608 The diffstat below is rather misleading as most insertions are due
609 to the new source documentation.
610
611 - autoconf cleanup
612 - para_server also uses the new error subsystem
613 - lots of new documentation (UTSL)
614 - gui improvements:
615 - keysyms for cursor keys and for next/previous page keys
616 - scrollable output window
617 - new internal commands: scroll up/down, page up/down
618 - fix color of command output.
619 - ortp: the --chunk_time and --header flags are no longer needed
620 for para_recv/para_audiod as this information is now encoded in
621 each rtp packet sent by para_server.
622
623 -------------------------------------------
624 0.2.9 (2006-01-24) "progressive turbulence"
625 -------------------------------------------
626
627 Internal audiod receivers/filters, the new error subsystem and
628 a lot of small improvements.
629
630 - para_recv and para_filter are integrated into the para_audiod
631 binary, i.e. audiod no longer spawns a new process for
632 each receiver/filter. As para_recv and para_filter might be
633 useful as standalone programs, they still get built (linked
634 against the same object files that are also used for audiod).
635 - further ortp timing improvements should reduce the CPU usage
636 of the ortp receiver.
637 - improved audio grabbing. The 'grab' command of para_audiod
638 has its own set of command line options. Read the output of
639 "para_audioc help grab" for more info.
640 - oggdec: configurable input prebuffer size.
641 - the new error subsystem gives better error diagnostics
642 and reduces code size.
643
644 -----------------------------------------
645 0.2.8 (2006-01-02) "dynamic accumulation"
646 -----------------------------------------
647
648 The new modular filter design and the para_play-hangs bugfix.
649
650 - new executable: para_filter. It combines para_mp3dec,
651 para_oggdec and para_compress. It also adds a further filter
652 type, wav, that just inserts a wave header at the desired point
653 of the filter chain. All 'piping' is done in-memory (i.e. no
654 read/write operations are used).
655 - para_play: fix a stupid bug that caused it to hang under
656 certain circumstances.
657
658 -------------------------------------------
659 0.2.7 (2006-12-27) "transparent invariance"
660 -------------------------------------------
661
662 Not many user-visible changes but a fair amount of internal improvements.
663
664
665 - The http sender buffers data if it can not be sent
666 out immediately (because the socket is not writable). This
667 should prevent para_server from shutting down the connection
668 too early on a loaded network.
669 - para_play also prebuffers data if it is told to start at a
670 future time by the --start_time option.
671 - The return of para_recv: It combines para_ortp_recv and
672 para_http_recv. Use the --receiver option to switch between
673 the two. para_recv builds without libortp, but contains
674 only the http receiver in this case.
675 - update to ortp 0.8.1. As this ortp release contains incompatible
676 changes, para_recv-0.2.7 won't link against older ortp libs.
677 - improved ortp timings.
678 - use of gcc-extensions that #define away for non-gcc and
679 gcc < 3.0.
680
681 -------------------------------------------
682 0.2.6 (2005-10-29) "recursive compensation"
683 -------------------------------------------
684
685 Transparent session encryption (uses openssl's Alleged RC4 cipher),
686 the internal find command and several other improvements and cleanups.
687
688 - Encrypt the session if encryption is requested by the client
689 (default for para_client 0.2.6). This is backwards
690 compatible, so older clients can still connect to para_server
691 0.2.6. Use the new client option --plain to request an
692 uncrypted session (off by default, must be set to on in
693 order to connect to para_server 0.2.x with 0 <= x <= 5).
694 - para_server uses an internal function to locate audio files
695 rather than calling find(1). The server option
696 --mysql_audio_file_dir replaces --mysql_find_cmd.
697 - documentation update
698 - man pages
699 - header file cleanup
700 - para_client code cleanup
701 - para_gui: faster display of output of display commands
702
703 ------------------------------------------
704 0.2.5 (2005-10-13) "aggressive resolution"
705 ------------------------------------------
706
707 This release adds internal senders, i.e. no more external programs are
708 spawned for sending out the audio data. There are two different senders
709 available: The http sender and the ortp sender (former para_send which
710 is no longer needed).
711
712 The new sender code has a plugin-like design so it can be easily
713 extended should there be be any future need for supporting another
714 network streaming protocol. All senders are completely independent of
715 each other. In particular, the http and the ortp sender can operate
716 in parallel.
717
718 - new server command: sender to control senders at runtime.
719 Read the output of "para_server -h" and "para_client help
720 sender" for more information.
721 - para_recv renamed to para_ortp_recv
722 - new executable: para_http_recv, a simple command line
723 http receiver.
724 - major afs/mp3/ogg code simplifications due to internal
725 senders.
726 - ogg timing improvements
727 - fix several minor memory leaks (found by valgrind)
728 - empty stream definitions work again
729 - com_ne(): ignore errors on remove
730 - audiod: fix segfault on server restart
731
732 ---------------------------------------
733 0.2.4 (2005-09-21) "toxic anticipation"
734 ---------------------------------------
735
736 Several small improvements, fixes and the new grab command.
737
738 - audiod:
739 - new command: "grab" to grab the output of the stream reader
740 or any filters. Read the output of "para_audioc help grab"
741 for more information.
742 - fix memory leak
743 - code cleanup
744 - audioc: new command line option: --bufsize to specify a
745 buffer size different from the default size 8192.
746 - improved error diagnostics for para_play.
747 - new configure option: --enable-ssldir so search for openssl in
748 non-standard places
749 - sdl_gui: Make it look nice again for 1024x768
750 - server: report total size of memory allocated with sbrk by malloc,
751 new command line option: --announce_time
752
753 -----------------------------------------
754 0.2.3 (2005-09-01) "hydrophilic movement"
755 -----------------------------------------
756
757 Two new executables and major feature enhancements.
758
759 - audiod filters: It is now possible to specify arbitrary many
760 (including none) filters for each supported audio
761 format. This can be used e.g. for normalizing volume,
762 transforming or grabbing the audio stream, or for using
763 visualizers. Read the output of "para_audiod -h" for the
764 syntax of the new --filter_cmd option.
765 - new executable: para_play, a tiny alsa player. It
766 can play wave files or raw pcm (16 bit little endian)
767 from stdin.
768 - new executable: para_compress, a dynamic range compressor
769 intended to keep audio output at a consistent volume. Derived
770 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
771 - audiod: New option: --stream_delay. This can be used in
772 a local network to syncronize the audio output of all
773 clients that play the same stream.
774
775 ------------------------------------------
776 0.2.2 (2005-08-19) "tangential excitation"
777 ------------------------------------------
778
779 Mostly internal changes in this release, but also some new commands
780 for the mysql database tool.
781
782 - cleanup exec.c, fix para_exec bug
783 - compile time loglevel (log messages below the given level
784 won't be compiled in, which reduces the size of the
785 resulting binaries)
786 - new log macros that shorten the size of the source code.
787 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
788 to send only zeros. With this workaround, para_audioc works
789 again.
790 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
791 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
792 (new entry), "snp" (set numplayed). Read the manual for more
793 information.
794
795 ---------------------------------------
796 0.2.1 (2005-08-15) "surreal experience"
797 ---------------------------------------
798
799 Here comes paraslash-0.2.1. It contains a couple of new features and,
800 surprise, only minor bug fixes.
801
802 - kill noisy mp3 debug message
803 - cleanup of the build system
804 - para_server and para_client directly use the crypto routines
805 of the openssl library rather than invoking the openssl command
806 line utitlity
807 - server/audiod: new option --user to switch to the given user
808 when invoked as root. Read the output of "para_server -h" for
809 more information.
810 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
811 status. Default: "para_audioc stat"
812 - sdl_gui: new option --pic_cmd to be used to download the picture.
813 Default: "para_client pic"
814 - audiod: 5 slots ought to be enough for everybody
815 - audiod: new status item: Uptime, kill hup command
816
817 ------------------------------------------
818 0.2.0 (2005-08-06) "distributed diffusion"
819 ------------------------------------------
820
821 After several month of increased development activity, paraslash-0.2.0
822 has arrived. It contains many new features and is much more
823 self-contained than the old 0.1.x series. Enjoy!
824
825
826 - para_server: fix hang on song change and crash on sighup.
827 Speed up mysql queries. The DIR_LIKE macro is gone.
828 - new executables: para_audiod, the local audio daemon that
829 starts playback (uses SCM_CREDENTIALS socket magic) and
830 para_audioc, the corresponding client.
831 - new executables: para_mp3dec/para_oggdec, two really teensy
832 decoders. para_mp3dec is based on libmad, para_oggdec requires
833 libvorbisfile.
834 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
835 they are now called para_send and para_recv respectively.
836 - documentation updates
837 - para_gui is themable. For now there is the default theme that
838 looks as before and the simple theme: blue and easy.
839 - gui: audio streaming is now handled by audiod. Time display shows
840 playback time rather than streaming time
841 - slider: update to libzmw-0.2.0
842 - para_krell: fix crash on server shutdown
843 - switch from gzip to bzip2
844
845 ----------------------------------------
846 0.1.7 (2005-04-18) "melting penetration"
847 ----------------------------------------
848
849 The main change in this release is clearly the oggvorbis rewrite,
850 but there are also lots of smaller changes. If you intend to use both
851 the mp3 and the ogg plugin, it is recommended to use software mixing,
852 e.g. the dmix plugin which is provided by ALSA.
853
854 - new executables: para_ovsend and para_ovrecv for sending/receiving
855 oggvorbis files via rtp. Requires the open rtp library. Get it at
856 http://www.linphone.org/ortp/
857 - rewrite of the ogg_vorbis core code
858 - configure detects libzmw and, if detected, includes
859 para_slider to the list of binaries to be built by make
860 - server stream writers read from their associated fifo rather
861 than from stdin
862 - slider: two new sliders, lastplayed and numplayed
863 - fix nasty double free bug which caused random segfaults in case of
864 mp3 files with invalid header information
865 - gui: new command line option: --stream_timeout=seconds to
866 deactivate a slot if it is idle for that many seconds (default=`5')
867 - diffstats
868
869 ---------------------------------------
870 0.1.6 (2005-03-05) "asymptotic balance"
871 ---------------------------------------
872
873 Only little user-visible changes in this release. Mainly bugfixes and
874 core code cleanup. This is probably the most stable version ever if you
875 stick to mp3...
876
877 - fix several memory leaks
878 - rename default name of mysql database from "music" to "paraslash".
879 Use para_server's --mysql_database option if you do not want to
880 rename your old database.
881 - rework ogg vorbis code
882 - make update command work on mysql servers with LOCAL_INFILE
883 disabled
884 - gui: improved stream I/O (slots)
885 - simplified audio format API
886 - para_pob_ogg is gone
887
888 ------------------------------------
889 0.1.5 (2004-12-31) "opaque eternity"
890 ------------------------------------
891
892 Let's slide gently into the new year.
893
894 - new: para_slider (not built automatically, type "make
895 para_slider" to build). A toy for those who always felt that
896 creating stream definitions is difficult. See screenshots,
897 README and FEATURES for more info.
898 - improved signal handling. Fixes server segfault on SIGHUP
899 for linux kernels newer than Aug 24 2004 and makes para_gui
900 race-free.
901 - reload database tool on SIGHUP
902 - improved help message for sl
903 - do not log "broken pipe" messages as errors. They are
904 perfectly ok.
905 - fix wrong error message on permission errors
906
907 -----------------------------------------
908 0.1.4 (2004-12-19) "tunneling transition"
909 -----------------------------------------
910
911 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
912 Hopefully, most of them got wiped out with this release. Some
913 enhancements went also in.
914
915 - improved error diagnostics for all commands
916 - stradd/picadd: overwrite previous contents if entry already
917 exists, rather than returning errors
918 - stradd: use current stream if invoked without args
919 - faster (and hopefully more stable) ogg-vorbis handling
920 - para_krell: reap children to avoid zombie-flooding in case
921 no server is running
922 - si: report also server pid
923 - server: don't busy-loop if dbtool reports only invalid files.
924 - gui: CTRL+C works again, fix stream_read command line option
925 - fix pic_add, hist
926 - fix mysql dbtool startup in case no database exists
927 - many small fixes and cleanups
928
929 ---------------------------------------
930 0.1.3: (2004-12-10) "vanishing inertia"
931 ---------------------------------------
932
933 Starting from this release, the database tools are integrated in the
934 server binary. This decreases server startup time, reduces code size
935 and speeds up database commands. However, the layout of the underlying
936 mysql database changed only slightly and 0.1.3 should be backwards
937 compatible in that respect.
938
939 Visible changes:
940
941 - If mysql is not detected at compile time, or fails to init
942 at runtime, fall back to the dopey database tool which should
943 always work.
944 - para_dbtool and dbtool.conf are gone. All mysql specific
945 options are read from server.conf and are prefixed by 'mysql_'.
946 - new command: cdt (change database tool)
947 - new command line option: dbtool (choose startup database tool)
948 - The name of current stream is now stored in the database,
949 so paraslash remembers its current stream when restarted.
950 - new command: csp (change stream and play)
951 - para_gui also reports current database tool and server uptime
952
953 -------------------------------------------
954 0.1.2: (2004-11-28) "spherical fluctuation"
955 -------------------------------------------
956
957 Point release before the big dbtool changes go in.
958
959 - dbtool: rename ca to cam (copy all meta data). It now also
960 copies numplayed and lastplayed time as well as the picture
961 id.
962 - fix endless-loop-bug caused by mp3 files with invalid header
963
964 -----------------------------------------
965 0.1.1: (2004-11-05) "floating atmosphere"
966 -----------------------------------------
967
968 - gkrellm plugin
969 - new dbtool command: mbox. Browse your sound-file collection
970 with your favorite mail reader.
971 - several small fixes
972
973 -------------------------------------
974 0.1.0: (2004-10-22) "rotating cortex"
975 -------------------------------------
976
977 - fix logging bug for loglevel > VERBOSE
978 - fix skip command
979 - correct timings for vbr mp3s
980 - modular audio format support
981 - ogg-vorbis support (experimental)
982 - new server option: autoplay
983
984 -----------------------------------------
985 0.0.99: (2004-07-25) "harmonic deviation"
986 -----------------------------------------
987
988 - rename projectname from icc to paraslash (play, archive, rate
989 and stream large audio sets happily)
990 - paraslash is no longer restricted to one particular audio
991 streaming software
992 - new dbtool commands (stradd, strq, strdel) for easy stream
993 managment w/o configuration file. That obsoletes stream_defs
994 file/config option for dbtool.
995 - picadd accepts jpeg data from stdin
996 - new server commands: ps (select previous stream), sc (song change)
997 - new default pictures for sdl_gui
998 - gui: new key_map option for binding commands and internal
999 functions to arbitrary keys, nice help screen, rip out
1000 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1001 show silly logo on startup
1002 - new executables: para_fade for fading volume, para_dbadm for
1003 manipulating attributes
1004 - cdb adds _all_ tables to mysql database
1005 - revised and beautified documentation
1006 - sample dbtool rewritten in C
1007 - autoconf
1008
1009 ---------------------------------------------
1010 0.0.98: (2003-12-26) "incremental smoothness"
1011 ---------------------------------------------
1012
1013 - kick icecast in favour of poc. That removes some races and reduces
1014 core code considerably.
1015 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1016 give finer info on afs' status.
1017 - gui can start decoder (see config options). Further new gui
1018 commands: refresh (^L), jmp (F1-F10)
1019 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1020 terminates gui. This fixes dead instances consuming memory
1021 continuously.
1022 - new dbtool command: verb for sending verbatim sql queries.
1023 - fix pid_list races (by removing pid_list)
1024 - codename funnies
1025
1026 --------------------
1027 0.0.97: (2003-10-26)
1028 --------------------
1029
1030 - installation prefix now defaults to /usr/local
1031 - new commands for gui: snozze, sleep and reread config
1032 - config file for gui and sdl_gui
1033 - fix problems with filenames containing funny characters
1034 (reported by Thomas Forell)
1035 - improved signal handling for gui, now it rereads conf on SIGHUP
1036 - new dbtool command: cdb (create database)
1037 - switch from argtable to gengetopt
1038 - major code cleanup and speed improvements
1039 - fix several potential buffer overflows
1040 - many small fixes and cleanups
1041
1042 -------------------
1043 0.0.96 (2003-08-30)
1044 -------------------
1045
1046 - easy stream_defs syntax
1047 - sdl_gui can display images associated to the file being played
1048 - Major feature enhancements for icc_gui including dynamic text
1049 placement and the top/bottom window design
1050 - vrfy/clean now also checks for NULL values in attributes as
1051 well as for invalid picture pointers
1052 - fix long outstanding case sensitivity bug
1053 - many small fixes and cleanups
