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

980 -------------------
981
982 - easy stream_defs syntax
983 - sdl_gui can display images associated to the file being played
984 - Major feature enhancements for icc_gui including dynamic text
985 placement and the top/bottom window design
986 - vrfy/clean now also checks for NULL values in attributes as
987 well as for invalid picture pointers
988 - fix long outstanding case sensitivity bug
989 - many small fixes and cleanups
990
991 -------------------
992 0.0.95 (2003-06-29)
993 -------------------
994
995 - sdl gui runs much faster
996 - new dbtool command: ca (copy attributes)
997 - count and display number of times the song has been played
998 - new feature: scoring
999 - command line options for sdl_gui
1000 - simpler syntax of streams file
1001 - decrease network traffic of stat
1002 - fix zombie bug
1003 - many small fixes and cleanups
1004
1005 -------------------
1006 0.0.94 (2003-05-04)
1007 -------------------
1008
1009 - new server command: ns (next stream)

1015 - many small fixes and cleanups
1016
1017 -------------------
1018 0.0.93 (2003-03-28)
1019 -------------------
1020
1021 - colors for icc_gui
1022 - icc_gui sets volume directly (linux only)
1023 - proper locking that fixes some races
1024 - fix security bug that caused commands to be executed even
1025 with unsufficient permissions
1026 - new command: hup to make all servers reread their configuration file
1027 - icecast meta data streaming
1028 - many small fixes and cleanups
