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