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

999 -------------------
1000
1001 - easy stream_defs syntax
1002 - sdl_gui can display images associated to the file being played
1003 - Major feature enhancements for icc_gui including dynamic text
1004 placement and the top/bottom window design
1005 - vrfy/clean now also checks for NULL values in attributes as
1006 well as for invalid picture pointers
1007 - fix long outstanding case sensitivity bug
1008 - many small fixes and cleanups
1009
1010 -------------------

1012 -------------------
1013
1014 - sdl gui runs much faster
1015 - new dbtool command: ca (copy attributes)
1016 - count and display number of times the song has been played
1017 - new feature: scoring
1018 - command line options for sdl_gui
1019 - simpler syntax of streams file
1020 - decrease network traffic of stat
1021 - fix zombie bug
1022 - many small fixes and cleanups
1023
1024 -------------------
1025 0.0.94 (2003-05-04)
1026 -------------------
1027
1028 - new server command: ns (next stream)
1029 - new icc_gui command: c (change stream)
1030 - internal mp3info
1031 - stat shows also id3 tag info
1032 - new sdl based gui
1033 - log flodding bug fixed
1034 - many small fixes and cleanups
1035
1036 -------------------
1037 0.0.93 (2003-03-28)
1038 -------------------
1039
1040 - colors for icc_gui
1041 - icc_gui sets volume directly (linux only)
1042 - proper locking that fixes some races
1043 - fix security bug that caused commands to be executed even
1044 with unsufficient permissions
1045 - new command: hup to make all servers reread their configuration file
1046 - icecast meta data streaming
1047 - many small fixes and cleanups
