1 -------------------------------------------
2 0.4.11 (to be announced) "mutual diversity"
3 -------------------------------------------
4
5 - Sideband connections: If both para_server and para_client
6 support this feature, data is sent as a multiplexed stream.
7 - The --no_default_filters option of para_filter has been
8 removed.
9 - Documentation improvements.
10
11 ------------------------------------------
12 0.4.10 (2012-03-30) "heterogeneous vacuum"
13 ------------------------------------------
14
15 Nothing earth-shaking in this release, but quite a few usability
16 improvements and the usual mix of cleanups and fixes.
17
18 - The --no_default_filters option of para_filter has been
19 deprecated. It still works but has no effect and will be
20 removed in the next version.
21 - para_gui now prints also the stderr output of the executing
22 command in the bottom window.
23 - Cleanup and consolidation of the various wrappers for
24 write(), writev(), send() and friends.
25 - The obscure error messages on mmap() failures have been
26 replaced by meaningful messages. This affects mainly
27 para_afh.
28 - para_audioc: Cleanups and memory leak fixes.
29 - Test 0004-server no longer fails if para_server is not
30 being built.
31 - New configure options: --with-id3tag-{headers,libs}.
32
33 -------------------------------------
34 0.4.9 (2011-12-06) "hybrid causality"
35 -------------------------------------
36
37 Support for another audio format, interactive mode for para_client
38 and para_audiod and many small improvements/fixes all over the place.
39
40 - Support for flac, the free lossless audio codec.
41 - Fix for an endless loop in the mp3 decoder for certain
42 (corrupt) mp3 files.
43 - When executed without specifying a command, para_client
44 and para_audioc start an interactive shell (requires
45 libreadline being installed). The interactive mode offers
46 full tab completion and command line history.
47 - autogen.sh now detects a distcc setup and adjusts the
48 parameter for the -j option of make accordingly.
49 - Shared memory areas are no longer restricted to 64K. We now
50 detect the maximal size of a shared memory area at runtime.
51 - cleanup of the internal uptime API.
52 - para_server prefaults the mmapped audio file to avoid
53 delays on slow media.
54 - A new test for the test-suite that exercises the
55 communication between para_server and para_audiod.
56 - The alsa writer eats up less CPU cycles when configured to
57 use the DMIX plugin.
58 - Simplified and unified receiver code.
59 - Makefile cleanups.
60 - Commands which print a list of matching audio files now
61 emit a meaningful error message if no audio file matched the
62 given pattern(s).
63
64 --------------------------------------
65 0.4.8 (2011-08-19) "nested assignment"
66 --------------------------------------
67
68 Gcrypt support, the overhauled osx writer and regex format specifiers
69 are the highlights of this release.
70
71 - support for libgcrypt as a drop-in replacement for openssl.
72 Run configure --enable-cryptolib=gcrypt to link against
73 libgcrypt. The two crypto implementations are compatible to
74 each other, i.e. a para_client executable linked against
75 gcrypt can connect to para_server linked against libssl
76 and vice versa.
77 - Rewrite of the osx writer (output plugin for Mac OS).
78 - audiod: The format specifier for receivers, filters and
79 writers is now treated as a regular expression. This allows
80 to replace 5 lines in the config file (one for each audio
81 format) by one single line. See the manual for details.
82 - The *.cmdline.[ch] files are no longer contained in the released
83 tarballs. This reduces the size of the tarballs but requires
84 gengetopt to build the tarball.
85 - Compiles cleanly also with llvm/clang.
86 - Corrupt mp3 files are handled more gracefully.
87 - The alsa writer uses poll fds instead of computing timeouts.
88 - Cleanup of the generic writer API.
89 - sched: Optimized zero timeouts.
90 - vss timeout cleanups.
91 - oggdec fixes and improvements.
92
93 --------------------------------------
94 0.4.7 (2011-06-01) "infinite rollback"
95 --------------------------------------
96
97 The new ao writer, support for ssh RSA keys and a couple of other
98 enhancements.
99
100 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
101 platforms through the libao audio library.
102 - Support for RSA keys generated with ssh-keygen.
103 - configure: improved options for ogg/vorbis/speex.
104 - The git version reported by --version always matches HEAD.
105 - The autogen script detects the number of processors and
106 runs a parallel make if possible.
107 - Major cleanup of the crypto API.
108 - Documentation updates.
109
110 ------------------------------------------
111 0.4.6 (2011-03-31) "deterministic entropy"
112 ------------------------------------------
113
114 Lots of ogg/vorbis improvements, the new test suite, enhancements
115 for para_gui and a fair amount of other bug fixes.
116
117 - For DCCP/OGG streams the audio file header is only sent once
118 at the beginning of the stream rather than periodically
119 every five seconds. This reduces network traffic and the
120 FEC group size.
121 - The vorbis comment header is replaced by an empty dummy header
122 before the header is sent over the network. This also results in
123 less network traffic and smaller FEC groups.
124 - The new "test" make target allows to perform some sanity checks prior
125 to installing the package.
126 - ogg timing fixes and performance improvements
127 - Scheduler improvements
128 - Proper exit codes for para_write
129 - para_gui: New option --theme to select a startup theme. Several
130 other improvements and fixes.
131 - aacdec error message cleanups
132 - simplified color error handling
133
134 --------------------------------------------
135 0.4.5 (2010-12-17) "symmetric randomization"
136 --------------------------------------------
137
138 Bug fixes, internal cleanups and variable-sized FEC slices.
139
140 - Contains a fix for an invalid-free-bug in the ogg audio format
141 handler code.
142 - Switching off the DCCP sender works again.
143 - para_audiod handles crashes of para_server more robustly.
144 - Internal scheduler and writer cleanups.
145 - Reduced latency due to variable-sized FEC slices.
146 - Improved documentation and error diagnostics.
147 - The build of para_server is now optional, allowing the build
148 to succeed in case libosl is not installed.
149
150 ------------------------------------------
151 0.4.4 (2010-08-06) "persistent regularity"
152 ------------------------------------------
153
154 Support for yet another audio format, para_write improvements and
155 bug fixes.
156
157 - Support for the speex codec.
158 - Support for sample formats other than 16 bit little endian.
159 - error2.h is now created by a perl script which speeds up configure
160 considerably.
161 - Fix a bug in the aac decoder which could lead to segfaults in
162 para_filter/para_audiod.
163 - Fixes for autoconf-2.66.
164
165 ----------------------------------------
166 0.4.3 (2010-07-05) "imaginary radiation"
167 ----------------------------------------
168
169 Many improvements for the DCCP and the UDP transport, the new user
170 manual and the usual mix of bug fixes and internal improvements.
171
172 - FEC support for the DCCP sender (Gerrit Renker). The new
173 --dccp_max_slice_size, --dccp_data_slices_per_group and
174 --dccp_slices_per_group options can be used to set the FEC
175 parameters for the DCCP transport.
176 - DNS lookups for UDP targets (Gerrit Renker).
177 - The new user manual replaces the README, README.afs, REQUIREMENTS
178 and INSTALL documents.
179 - Fix an end-of-file detection bug in the oggdec filter.
180 - The new nonblock API.
181 - Both options of the oggdec filter have been removed.
182 - New debug mode for the internal scheduler.
183
184 ------------------------------------------
185 0.4.2 (2010-04-23) "associative expansion"
186 ------------------------------------------
187
188 It's been some time since the last release, but finally here is
189 paraslash-0.4.2. The bulk of the changes comes from the new buffer
190 tree API, but there are changes all over the tree. Mainly performance
191 and usability improvements, but also quite some bug fixes.
192
193 - The new buffer tree API.
194 - DCCP: Support for CCID negotiation (Gerrit Renker).
195 - UDP robustness fixes.
196 - The --bufsize option for mp3dec is gone as it no longer makes sense
197 for the new buffer tree API.
198 - Fix audible buffer underruns for wma streams.
199 - The alsa writer no longer prints meaningless underrun durations.
200 - audiod: Defaults work also for udp streams. If no filter is
201 given for an audio format that is received via upd, fecdec is
202 automatically added as the first filter (along with the decoder).
203
204 ---------------------------------------
205 0.4.1 (2009-12-22) "concurrent horizon"
206 ---------------------------------------
207
208 Support for another audio format, minor feature enhancements and lots of bug
209 fixes. All fixes that have been accumulated in the maint branch (in particular
210 those mentionened in the 0.3.6 release notes) appear in this release as well.
211
212 - wma support.
213 - new afh option: --human to activate human-readable output.
214 - new server/audiod option: --log-timing to print timing information.
215 - build system improvements.
216 - source code documentation updates.
217
218 -------------------------------------
219 0.3.6 (2009-12-07) "cubic continuity"
220 -------------------------------------
221
222 Quite a few bugs have been found and fixed since 0.3.5, so here's
223 another 0.3.x release. No new features.
224
225 - Always check return value of malloc().
226 - ogg vorbis/FEC: Do not write garbage after the audio file header.
227 - exit if root privileges could not be dropped.
228 - FEC: Fix computation of extra slices.
229 - oss: Fix check for empty input buffer.
230 - Avoid buffer underruns due to filter chain output buffer constraints.
231 - server: Fix assignment of afs_pid.
232 - Don't panic if the afs database contains unknown audio formats.
233 - http/dccp: Do not send the audio file header twice.
234 - FEC: Timing improvements.
235
236 ----------------------------------------------
237 0.4.0 (2009-11-10) "simultaneous independence"
238 ----------------------------------------------
239
240 Two significant changes which require the new version number: The
241 improved authentication dialog and the fact that the database code
242 has been moved to a library, libosl. To use the new version, you have
243 to generate new RSA keys, see INSTALL for details. A shell script is
244 provided for conversion of the 0.3 database to the new 0.4 format.
245
246 - stronger crypto for client authentication
247 - the database code has been moved to a library
248 - improved status item handling
249 - cleanup of the build system
250 - The "-V" option now also prints the git version
251 - the new parser-friendly listing mode for the ls and stat commands
252 - mandatory rc4 encryption
253 - major audio format handler cleanups
254 - (id3,...) tags are no longer stored as a combined string in the database
255 - new mood methods: artist_matches, title_matches, comment_matches,
256 album_matches, year_maches, year.
257
258 --------------------------------------------
259 0.3.5 (2009-09-21) "symplectic separability"
260 --------------------------------------------
261
262 Full client support for *BSD Unixes, complete re-write of the ogg
263 vorbis audio format handler, various improvements all over the place
264 and the usual mix of bugfixes. This release marks the end of the 0.3
265 series if no serious problems show up.
266
267 - the new oss writer (supported on *BSD and Linux)
268 - rewrite of the ogg vorbis audio format handler. It's
269 recommended to replace the chunk tables of existing ogg
270 vorbis files in the afs database by re-adding these files
271 with "add -f".
272 - support for netmask subsets (Gerrit Renker)
273 - the new prebuffer filter
274 - improved signal handling
275 - variable fec output buffer size
276 - improved FEC timing fixes audible buffer underruns in UDP mode
277 - --log_color actually works
278 - new ls option: -d (print dates as seconds after the epoch)
279 - update to gengetopt 2.22.2
280 - support for RSA keys of size > 512 bits
281 - new option "mixer_channel" for para_fade
282
283 -----------------------------------------
284 0.3.4 (2009-05-07) "elliptic inheritance"
285 -----------------------------------------
286
287 The new udp sender, forward error correction, colored logs and various
288 other improvements. As the udp sender does not depend on any special
289 libraries, it is built unconditionally.
290
291 - The udp sender replaces the ortp sender. The new code uses forward
292 error correction to protect against packet losses. Many thanks to
293 Gerrit Renker for providing ipv6 support.
294 - The default port for udp streaming now defaults to 8000, like
295 for the http and the dccp senders/receivers.
296 - Loglevels are now specified as symbolic names, e.g.
297 "--loglevel info".
298 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
299 - para_server/para_audiod: Color support for log messages.
300 - new options for mp3dec: --ignore-crc, --bufsize
301 - new audiod option: --config-file.
302 - gengetopt cleanups.
303 - Improved help/man pages: The documentation of para_audiod,
304 para_recv, para_filter and para_write now also contains
305 all options of the available receivers/filters/writers. The
306 man page of para_fade contains a description of the different
307 modes of operation.
308 - More source code documentation.
309 - vss timing fixes.
310
311 --------------------------------------------
312 0.3.3 (2008-12-01) "axiomatic perspectivity"
313 --------------------------------------------
314
315 Internal code cleanups, bug fixes, improved tag handling and the new
316 amplification filter.
317
318 - para_server uses the generic scheduling code.
319 - overhaul of the virtual streaming system.
320 - mp3: id3 version 2 support via libid3tag (optional)
321 - ogg: vorbis comment support.
322 - aac meta info support.
323 - mp3 audio format handler cleanups.
324 - new filter: "amp" to amplify the amplitude of the audio stream
325 - new status item/database entry: amplification. It is
326 used by the amp filter to pre-amplify the audio stream.
327 - fix a close-without-open bug in para_write.
328 - fix a bug in com_init() which was introduced in 0.3.2.
329 - better error diagnostics for para_client.
330
331 -----------------------------------------
332 0.3.2 (2008-04-11) "probabilistic parity"
333 -----------------------------------------
334
335 The new para_afh executable, scheduling and documentation improvements.
336
337 - new ls option: -lc (list chunk table)
338 - new executable: para_afh, the stand-alone audio file handler tool
339 - afs commands can send output more than SHMMAX (32MB on Linux). This
340 also reduces the memory usage of commands that produce large amounts
341 of output.
342 - major scheduler and audiod cleanups.
343 - more detailed and much nicer man pages.
344
345 ---------------------------------------
346 0.3.1 (2008-02-23) "liquid interaction"
347 ---------------------------------------
348
349 A mix of cleanups, bug fixes, improvements, and some new features. No
350 significant changes to the new database (osl) code, which is generally
351 a good sign.
352
353 - Share some similar/duplicate code between the http and the
354 dccp sender.
355 - Generic access control lists for paraslash senders.
356 - dccp sender: Access control lists, connection limiting and support
357 for the allow,deny,on,off,help sender commands.
358 - The default dccp port changed from 5001 to 8000 (suggested by
359 Gerrit Renker).
360 - para_server starts even if not all public keys could be loaded.
361 - Audiod performance improvements.
362 - fix a bug in the "off" command of the http sender.
363 - fix some fd and memory leaks.
364 - Update to gengetopt-2.22.
365
366 -------------------------------------
367 0.3.0 (2008-01-12) "solar saturation"
368 -------------------------------------
369
370 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
371
372
373 Usually one might expect lots of new features AND a big increase in size
374 for a major release like this.
375
376 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
377 ever. The decrease in size is mostly due to the removal of some
378 graphical tools (which were only quick hacks anyway). But also the
379 fact that the mysql code is gone cuts down the size a bit.
380
381 Being independent of mysql comes at a cost: The fact that paraslash
382 now contains its own database (the object storage layer, osl) increases
383 the (stripped) binary size of para_server by ~50K on i386.
384
385 - no more restrictions on unique basenames.
386 - independent of mysql: The new self-contained object
387 storage layer (osl) replaces the mysql database.
388 - New executable para_fsck: Check integrity of osl tables.
389 - Lyrics support.
390 - Reliable audio file move/rename detection.
391 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
392 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
393 Solaris (sparc64).
394 - the new osl-based audio file selector (afs) replaces the random,
395 the playlist and the mysql selector of paraslash-0.2.x.
396 - IPv6 support (thanks to Gerrit Renker).
397 - paraslash-0.2.x streams are now called "moods". Writing
398 0.3.x-mood definitions should be both easier and more
399 powerful than writing 0.2.x-stream definitions.
400 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
401 been removed. The world is a better place without them. However,
402 para_gui is still there.
403 - afs tracks audio file selection also in playlist mode.
404 - few easy-to-use afs commands replace the many not-so-easy-to-use
405 mysql commands (and are available also in playlist mode).
406 - Improved error subsystem.
407 - The earth-shaking new logo.
408
409 -----------------------------------------
410 0.2.17 (2007-11-20) "isotropic threshold"
411 -----------------------------------------
412
413 Mainly bugfixes and cleanups in this version which marks the end of
414 the 0.2.x series if no serious bugs show up after the release.
415
416 - mysql_selector: fix a locking bug.
417 - universal chunk queueing.
418 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
419 to Gerrit Renker).
420 - be more carful wrt. signed vs. unsigned argument passing.
421 - cleanup error.h and fix some references to invalid error
422 codes.
423 - update to gengetopt-2.21.
424 - update to ortp-0.13.1.
425 - autoconf: extend checks for headers, library functions and
426 compiler characteristics.
427 - Fix streaming of large mp3 files.
428 - Fix an off-by-one bug in playlist handling.
429
430 --------------------------------------
431 0.2.16 (2007-04-05) "neural discharge"
432 --------------------------------------
433
434 The main change in this release is the major audio format handler
435 cleanup which removes some similar/duplicate code and makes it easier
436 to implement plugins for other audio formats. Of course, the usual mix
437 of other improvements/changes/bugfixes also made it into the release.
438
439 - simplified audio format handlers (most of the handling functions
440 were moved one layer up to the virtual streaming system).
441 - para_server uses mmap to read audio files
442 - repositioning of mp3 streams is much faster, in particular for
443 jumping near the end of large mp3 files.
444 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
445 and AFS_WRITE.
446 - fix a bug in para_filter that caused decoding of aac files
447 to start only after a few seconds.
448 - fix osx_writer hangs
449 - simplified dccp code (thanks to Gerrit Renker)
450 - the compress filter works also on big endian systems (ppc)
451
452 -----------------------------------------
453 0.2.15 (2007-02-16) "inductive resonance"
454 -----------------------------------------
455
456 Minor improvements, more documentation and a bunch of bug fixes.
457
458 - para_server: The server.users file is only read once on server
459 startup rather than for each connection
460 - mp3dec: Fix decoding of corrupt mp3 files
461 - afs (audio file sender) is now called vss (virtual streaming
462 system). Consequently, the permission flags specified in
463 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
464 become VSS_READ and VSS_WRITE respectively.
465 - para_audiod/para_filter: Fix a bug that caused the last chunk
466 of audio data not being written under certain circumstances
467 - audiod: compute the difference of server time and local time
468 correctly
469 - para_server/para_audiod: Fix some memory leaks
470 - documentation improvements
471 - configure.ac: fix checks for para_krell
472 - new man pages
473
474 -------------------------------------------
475 0.2.14 (2006-10-15) "transient singularity"
476 -------------------------------------------
477
478 The only major enhancement of this version is the osx writer which completes
479 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
480 until now for reasons beyond the scope of this changelog entry.
481
482 - new output plugin for Mac Os: the osx writer
483 - rename configure command line options from --enable-xxx-headers to
484 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
485 - configure: new command line options: --with-mad-headers,
486 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
487 - some robustness fixes
488 - dymamic audio format recognition for audiod
489 - para_server: new command line option: --autoplay_delay
490 - para_audiod: new command line option: --clock_diff_count
491
492 ---------------------------------------
493 0.2.13 (2006-07-14) "sonic convolution"
494 ---------------------------------------
495
496 A bunch of new features and core changes.
497
498 - the new paraslash scheduler, short and sweet.
499 - Support for m4a/mp4 files via the new aac audio format
500 handler/filter (requires libfaad).
501 - each writer has its own command line parser, just like
502 para_recv and para_filter.
503 - para_client and para_audioc use the error subsystem
504 - writers are integrated in para_audiod (currently linux-only)
505 - para_client is integrated in para_audiod
506 - random/playlist selector: improved info strings
507 - new audiod commands: tasks, kill
508 - update to libortp-0.10.1
509 - para_fade: wake time defaults to 8 hours from now
510 - update to autoconf-2.60
511
512
513 ------------------------------------------
514 0.2.12 (2006-05-12) "oriented abstraction"
515 ------------------------------------------
516
517 Many user-visible changes in this release and lots of new
518 features:
519
520
521 - the new optional dccp sender/receiver. It uses the datagram
522 congestion control protocol. You'll need a fairly new kernel
523 for this.
524 - paraslash works on Mac OS X (thanks to Gerd Becker)
525 - para_play renamed to para_write
526 - modular output plugin design (writers) for para_write
527 - new file_writer output plugin for para_write
528 - compress filter speed improvements
529 - update to libortp-0.9.1
530 - update to gengetopt-2.17rc
531 - para_client no longer depends on libreadline (as the
532 code for the interactive mode was removed).
533 - gcc-2-95 is no longer a supported compiler. It may still
534 work, but it gets no more testing.
535 - the tarball no longer contains the screenshot images which
536 reduces its size quite a bit.
537 - configure: new command line options: --enable-mysql-headers
538 and --enable-mysql-libs
539
540 ------------------------------------
541 0.2.11 (2006-03-11) "atomic duality"
542 ------------------------------------
543
544 Here it is, the first paraslash release developed with git. There
545 are fairly many user-visible changes in this release. As two out of
546 the three "database tools" of paraslash don't use a database at all,
547 they are now called "audio file selectors" instead.
548
549
550 - the cdt command (change database tool) becomes chs (change
551 selector)
552 - no more colon separators: The syntax of some options of
553 para_audiod and para_filter have changed. Use --help for
554 more info (and some examples).
555 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
556 - switch from cvs to git (should've done that earlier)
557 - the new ipc subsystem
558 - new audio file selector: playlist
559 - para_server: the dopey selector is now called "random",
560 and is the default selector. Use the --selector option to
561 choose another selector at startup, or the chs command to
562 change the selector at runtime.
563 - X86_64 fixes (thanks to Steffen Klassert)
564 - para_play fixes
565
566
567 --------------------------------------
568 0.2.10 (2006-02-17) "cyclic attractor"
569 --------------------------------------
570
571 Huge documentation update, a scrollable window for para_gui, ortp
572 improvements, and of course many small fixes not mentioned here.
573 The diffstat below is rather misleading as most insertions are due
574 to the new source documentation.
575
576 - autoconf cleanup
577 - para_server also uses the new error subsystem
578 - lots of new documentation (UTSL)
579 - gui improvements:
580 - keysyms for cursor keys and for next/previous page keys
581 - scrollable output window
582 - new internal commands: scroll up/down, page up/down
583 - fix color of command output.
584 - ortp: the --chunk_time and --header flags are no longer needed
585 for para_recv/para_audiod as this information is now encoded in
586 each rtp packet sent by para_server.
587
588
589 -------------------------------------------
590 0.2.9 (2006-01-24) "progressive turbulence"
591 -------------------------------------------
592
593 Internal audiod receivers/filters, the new error subsystem and
594 a lot of small improvements.
595
596 - para_recv and para_filter are integrated into the para_audiod
597 binary, i.e. audiod no longer spawns a new process for
598 each receiver/filter. As para_recv and para_filter might be
599 useful as standalone programs, they still get built (linked
600 against the same object files that are also used for audiod).
601 - further ortp timing improvements should reduce the CPU usage
602 of the ortp receiver.
603 - improved audio grabbing. The 'grab' command of para_audiod
604 has its own set of command line options. Read the output of
605 "para_audioc help grab" for more info.
606 - oggdec: configurable input prebuffer size.
607 - the new error subsystem gives better error diagnostics
608 and reduces code size.
609
610
611 -----------------------------------------
612 0.2.8 (2006-01-02) "dynamic accumulation"
613 -----------------------------------------
614
615 The new modular filter design and the para_play-hangs bugfix.
616
617 - new executable: para_filter. It combines para_mp3dec,
618 para_oggdec and para_compress. It also adds a further filter
619 type, wav, that just inserts a wave header at the desired point
620 of the filter chain. All 'piping' is done in-memory (i.e. no
621 read/write operations are used).
622 - para_play: fix a stupid bug that caused it to hang under
623 certain circumstances.
624
625
626 -------------------------------------------
627 0.2.7 (2006-12-27) "transparent invariance"
628 -------------------------------------------
629
630 Not many user-visible changes but a fair amount of internal improvements.
631
632
633 - The http sender buffers data if it can not be sent
634 out immediately (because the socket is not writable). This
635 should prevent para_server from shutting down the connection
636 too early on a loaded network.
637 - para_play also prebuffers data if it is told to start at a
638 future time by the --start_time option.
639 - The return of para_recv: It combines para_ortp_recv and
640 para_http_recv. Use the --receiver option to switch between
641 the two. para_recv builds without libortp, but contains
642 only the http receiver in this case.
643 - update to ortp 0.8.1. As this ortp release contains incompatible
644 changes, para_recv-0.2.7 won't link against older ortp libs.
645 - improved ortp timings.
646 - use of gcc-extensions that #define away for non-gcc and
647 gcc < 3.0.
648
649
650 -------------------------------------------
651 0.2.6 (2005-10-29) "recursive compensation"
652 -------------------------------------------
653
654 Transparent session encryption (uses openssl's Alleged RC4 cipher),
655 the internal find command and several other improvements and cleanups.
656
657 - Encrypt the session if encryption is requested by the client
658 (default for para_client 0.2.6). This is backwards
659 compatible, so older clients can still connect to para_server
660 0.2.6. Use the new client option --plain to request an
661 uncrypted session (off by default, must be set to on in
662 order to connect to para_server 0.2.x with 0 <= x <= 5).
663 - para_server uses an internal function to locate audio files
664 rather than calling find(1). The server option
665 --mysql_audio_file_dir replaces --mysql_find_cmd.
666 - documentation update
667 - man pages
668 - header file cleanup
669 - para_client code cleanup
670 - para_gui: faster display of output of display commands
671
672
673 ------------------------------------------
674 0.2.5 (2005-10-13) "aggressive resolution"
675 ------------------------------------------
676
677 This release adds internal senders, i.e. no more external programs are
678 spawned for sending out the audio data. There are two different senders
679 available: The http sender and the ortp sender (former para_send which
680 is no longer needed).
681
682 The new sender code has a plugin-like design so it can be easily
683 extended should there be be any future need for supporting another
684 network streaming protocol. All senders are completely independent of
685 each other. In particular, the http and the ortp sender can operate
686 in parallel.
687
688 - new server command: sender to control senders at runtime.
689 Read the output of "para_server -h" and "para_client help
690 sender" for more information.
691 - para_recv renamed to para_ortp_recv
692 - new executable: para_http_recv, a simple command line
693 http receiver.
694 - major afs/mp3/ogg code simplifications due to internal
695 senders.
696 - ogg timing improvements
697 - fix several minor memory leaks (found by valgrind)
698 - empty stream definitions work again
699 - com_ne(): ignore errors on remove
700 - audiod: fix segfault on server restart
701
702
703 ---------------------------------------
704 0.2.4 (2005-09-21) "toxic anticipation"
705 ---------------------------------------
706
707 Several small improvements, fixes and the new grab command.
708
709 - audiod:
710 - new command: "grab" to grab the output of the stream reader
711 or any filters. Read the output of "para_audioc help grab"
712 for more information.
713 - fix memory leak
714 - code cleanup
715 - audioc: new command line option: --bufsize to specify a
716 buffer size different from the default size 8192.
717 - improved error diagnostics for para_play.
718 - new configure option: --enable-ssldir so search for openssl in
719 non-standard places
720 - sdl_gui: Make it look nice again for 1024x768
721 - server: report total size of memory allocated with sbrk by malloc,
722 new command line option: --announce_time
723
724
725 -----------------------------------------
726 0.2.3 (2005-09-01) "hydrophilic movement"
727 -----------------------------------------
728
729 Two new executables and major feature enhancements.
730
731 - audiod filters: It is now possible to specify arbitrary many
732 (including none) filters for each supported audio
733 format. This can be used e.g. for normalizing volume,
734 transforming or grabbing the audio stream, or for using
735 visualizers. Read the output of "para_audiod -h" for the
736 syntax of the new --filter_cmd option.
737 - new executable: para_play, a tiny alsa player. It
738 can play wave files or raw pcm (16 bit little endian)
739 from stdin.
740 - new executable: para_compress, a dynamic range compressor
741 intended to keep audio output at a consistent volume. Derived
742 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
743 - audiod: New option: --stream_delay. This can be used in
744 a local network to syncronize the audio output of all
745 clients that play the same stream.
746
747
748 ------------------------------------------
749 0.2.2 (2005-08-19) "tangential excitation"
750 ------------------------------------------
751
752 Mostly internal changes in this release, but also some new commands
753 for the mysql database tool.
754
755 - cleanup exec.c, fix para_exec bug
756 - compile time loglevel (log messages below the given level
757 won't be compiled in, which reduces the size of the
758 resulting binaries)
759 - new log macros that shorten the size of the source code.
760 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
761 to send only zeros. With this workaround, para_audioc works
762 again.
763 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
764 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
765 (new entry), "snp" (set numplayed). Read the manual for more
766 information.
767
768
769 ---------------------------------------
770 0.2.1 (2005-08-15) "surreal experience"
771 ---------------------------------------
772
773 Here comes paraslash-0.2.1. It contains a couple of new features and,
774 surprise, only minor bug fixes.
775
776 - kill noisy mp3 debug message
777 - cleanup of the build system
778 - para_server and para_client directly use the crypto routines
779 of the openssl library rather than invoking the openssl command
780 line utitlity
781 - server/audiod: new option --user to switch to the given user
782 when invoked as root. Read the output of "para_server -h" for
783 more information.
784 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
785 status. Default: "para_audioc stat"
786 - sdl_gui: new option --pic_cmd to be used to download the picture.
787 Default: "para_client pic"
788 - audiod: 5 slots ought to be enough for everybody
789 - audiod: new status item: Uptime, kill hup command
790
791
792
793 ------------------------------------------
794 0.2.0 (2005-08-06) "distributed diffusion"
795 ------------------------------------------
796
797 After several month of increased development activity, paraslash-0.2.0
798 has arrived. It contains many new features and is much more
799 self-contained than the old 0.1.x series. Enjoy!
800
801
802 - para_server: fix hang on song change and crash on sighup.
803 Speed up mysql queries. The DIR_LIKE macro is gone.
804 - new executables: para_audiod, the local audio daemon that
805 starts playback (uses SCM_CREDENTIALS socket magic) and
806 para_audioc, the corresponding client.
807 - new executables: para_mp3dec/para_oggdec, two really teensy
808 decoders. para_mp3dec is based on libmad, para_oggdec requires
809 libvorbisfile.
810 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
811 they are now called para_send and para_recv respectively.
812 - documentation updates
813 - para_gui is themable. For now there is the default theme that
814 looks as before and the simple theme: blue and easy.
815 - gui: audio streaming is now handled by audiod. Time display shows
816 playback time rather than streaming time
817 - slider: update to libzmw-0.2.0
818 - para_krell: fix crash on server shutdown
819 - switch from gzip to bzip2
820
821
822 ----------------------------------------
823 0.1.7 (2005-04-18) "melting penetration"
824 ----------------------------------------
825
826 The main change in this release is clearly the oggvorbis rewrite,
827 but there are also lots of smaller changes. If you intend to use both
828 the mp3 and the ogg plugin, it is recommended to use software mixing,
829 e.g. the dmix plugin which is provided by ALSA.
830
831 - new executables: para_ovsend and para_ovrecv for sending/receiving
832 oggvorbis files via rtp. Requires the open rtp library. Get it at
833 http://www.linphone.org/ortp/
834 - rewrite of the ogg_vorbis core code
835 - configure detects libzmw and, if detected, includes
836 para_slider to the list of binaries to be built by make
837 - server stream writers read from their associated fifo rather
838 than from stdin
839 - slider: two new sliders, lastplayed and numplayed
840 - fix nasty double free bug which caused random segfaults in case of
841 mp3 files with invalid header information
842 - gui: new command line option: --stream_timeout=seconds to
843 deactivate a slot if it is idle for that many seconds (default=`5')
844 - diffstats
845
846
847 ---------------------------------------
848 0.1.6 (2005-03-05) "asymptotic balance"
849 ---------------------------------------
850
851 Only little user-visible changes in this release. Mainly bugfixes and
852 core code cleanup. This is probably the most stable version ever if you
853 stick to mp3...
854
855 - fix several memory leaks
856 - rename default name of mysql database from "music" to "paraslash".
857 Use para_server's --mysql_database option if you do not want to
858 rename your old database.
859 - rework ogg vorbis code
860 - make update command work on mysql servers with LOCAL_INFILE
861 disabled
862 - gui: improved stream I/O (slots)
863 - simplified audio format API
864 - para_pob_ogg is gone
865
866 ------------------------------------
867 0.1.5 (2004-12-31) "opaque eternity"
868 ------------------------------------
869
870 Let's slide gently into the new year.
871
872 - new: para_slider (not built automatically, type "make
873 para_slider" to build). A toy for those who always felt that
874 creating stream definitions is difficult. See screenshots,
875 README and FEATURES for more info.
876 - improved signal handling. Fixes server segfault on SIGHUP
877 for linux kernels newer than Aug 24 2004 and makes para_gui
878 race-free.
879 - reload database tool on SIGHUP
880 - improved help message for sl
881 - do not log "broken pipe" messages as errors. They are
882 perfectly ok.
883 - fix wrong error message on permission errors
884
885 -----------------------------------------
886 0.1.4 (2004-12-19) "tunneling transition"
887 -----------------------------------------
888
889 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
890 Hopefully, most of them got wiped out with this release. Some
891 enhancements went also in.
892
893 - improved error diagnostics for all commands
894 - stradd/picadd: overwrite previous contents if entry already
895 exists, rather than returning errors
896 - stradd: use current stream if invoked without args
897 - faster (and hopefully more stable) ogg-vorbis handling
898 - para_krell: reap children to avoid zombie-flooding in case
899 no server is running
900 - si: report also server pid
901 - server: don't busy-loop if dbtool reports only invalid files.
902 - gui: CTRL+C works again, fix stream_read command line option
903 - fix pic_add, hist
904 - fix mysql dbtool startup in case no database exists
905 - many small fixes and cleanups
906
907 ---------------------------------------
908 0.1.3: (2004-12-10) "vanishing inertia"
909 ---------------------------------------
910
911 Starting from this release, the database tools are integrated in the
912 server binary. This decreases server startup time, reduces code size
913 and speeds up database commands. However, the layout of the underlying
914 mysql database changed only slightly and 0.1.3 should be backwards
915 compatible in that respect.
916
917 Visible changes:
918
919 - If mysql is not detected at compile time, or fails to init
920 at runtime, fall back to the dopey database tool which should
921 always work.
922 - para_dbtool and dbtool.conf are gone. All mysql specific
923 options are read from server.conf and are prefixed by 'mysql_'.
924 - new command: cdt (change database tool)
925 - new command line option: dbtool (choose startup database tool)
926 - The name of current stream is now stored in the database,
927 so paraslash remembers its current stream when restarted.
928 - new command: csp (change stream and play)
929 - para_gui also reports current database tool and server uptime
930
931
932 -------------------------------------------
933 0.1.2: (2004-11-28) "spherical fluctuation"
934 -------------------------------------------
935
936 Point release before the big dbtool changes go in.
937
938 - dbtool: rename ca to cam (copy all meta data). It now also
939 copies numplayed and lastplayed time as well as the picture
940 id.
941 - fix endless-loop-bug caused by mp3 files with invalid header
942
943 -----------------------------------------
944 0.1.1: (2004-11-05) "floating atmosphere"
945 -----------------------------------------
946
947 - gkrellm plugin
948 - new dbtool command: mbox. Browse your sound-file collection
949 with your favorite mail reader.
950 - several small fixes
951
952 -------------------------------------
953 0.1.0: (2204-10-22) "rotating cortex"
954 -------------------------------------
955
956 - fix logging bug for loglevel > VERBOSE
957 - fix skip command
958 - correct timings for vbr mp3s
959 - modular audio format support
960 - ogg-vorbis support (experimental)
961 - new server option: autoplay
962
963 -----------------------------------------
964 0.0.99: (2004-07-25) "harmonic deviation"
965 -----------------------------------------
966
967 - rename projectname from icc to paraslash (play, archive, rate
968 and stream large audio sets happily)
969 - paraslash is no longer restricted to one particular audio
970 streaming software
971 - new dbtool commands (stradd, strq, strdel) for easy stream
972 managment w/o configuration file. That obsoletes stream_defs
973 file/config option for dbtool.
974 - picadd accepts jpeg data from stdin
975 - new server commands: ps (select previous stream), sc (song change)
976 - new default pictures for sdl_gui
977 - gui: new key_map option for binding commands and internal
978 functions to arbitrary keys, nice help screen, rip out
979 soundcard/linux specific stuff, avoid noise artefacts while jumping,
980 show silly logo on startup
981 - new executables: para_fade for fading volume, para_dbadm for
982 manipulating attributes
983 - cdb adds _all_ tables to mysql database
984 - revised and beautified documentation
985 - sample dbtool rewritten in C
986 - autoconf
987
988 ---------------------------------------------
989 0.0.98: (2003-12-26) "incremental smoothness"
990 ---------------------------------------------
991
992 - kick icecast in favour of poc. That removes some races and reduces
993 core code considerably.
994 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
995 give finer info on afs' status.
996 - gui can start decoder (see config options). Further new gui
997 commands: refresh (^L), jmp (F1-F10)
998 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
999 terminates gui. This fixes dead instances consuming memory
1000 continuously.
1001 - new dbtool command: verb for sending verbatim sql queries.
1002 - fix pid_list races (by removing pid_list)
1003 - codename funnies
1004
1005 --------------------
1006 0.0.97: (2003-10-26)
1007 --------------------
1008
1009 - installation prefix now defaults to /usr/local
1010 - new commands for gui: snozze, sleep and reread config
1011 - config file for gui and sdl_gui
1012 - fix problems with filenames containing funny characters
1013 (reported by Thomas Forell)
1014 - improved signal handling for gui, now it rereads conf on SIGHUP
1015 - new dbtool command: cdb (create database)
1016 - switch from argtable to gengetopt
1017 - major code cleanup and speed improvements
1018 - fix several potential buffer overflows
1019 - many small fixes and cleanups
1020
1021 -------------------
1022 0.0.96 (2003-08-30)
1023 -------------------
1024
1025 - easy stream_defs syntax
1026 - sdl_gui can display images associated to the file being played
1027 - Major feature enhancements for icc_gui including dynamic text
1028 placement and the top/bottom window design
1029 - vrfy/clean now also checks for NULL values in attributes as
1030 well as for invalid picture pointers
1031 - fix long outstanding case sensitivity bug
1032 - many small fixes and cleanups
1033
1034 -------------------
1035 0.0.95 (2003-06-29)
1036 -------------------
1037
1038 - sdl gui runs much faster
1039 - new dbtool command: ca (copy attributes)
1040 - count and display number of times the song has been played
1041 - new feature: scoring
1042 - command line options for sdl_gui
1043 - simpler syntax of streams file
1044 - decrease network traffic of stat
1045 - fix zombie bug
1046 - many small fixes and cleanups
1047
1048 -------------------
1049 0.0.94 (2003-05-04)
1050 -------------------
1051
1052 - new server command: ns (next stream)
1053 - new icc_gui command: c (change stream)
1054 - internal mp3info
1055 - stat shows also id3 tag info
1056 - new sdl based gui
1057 - log flodding bug fixed
1058 - many small fixes and cleanups
1059
1060 -------------------
1061 0.0.93 (2003-03-28)
1062 -------------------
1063
1064 - colors for icc_gui
1065 - icc_gui sets volume directly (linux only)
1066 - proper locking that fixes some races
1067 - fix security bug that caused commands to be executed even
1068 with unsufficient permissions
1069 - new command: hup to make all servers reread their configuration file
1070 - icecast meta data streaming
1071 - many small fixes and cleanups
