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