1 ---------------------------------------------
2 0.?.? (to be announced) "volatile relativity"
3 ---------------------------------------------
4
5 --------------------------------------
6 0.4.11 (2012-07-20) "mutual diversity"
7 --------------------------------------
8
9 The major feature in this release is the new sideband API for
10 client-server communication. This API will be used exclusively starting
11 with 0.5.0, which breaks backward compatibility but allows to get rid
12 of quite some compatibility code. Other noteworthy changes include
13 decoder latency improvements and a long-standing bug fix for the
14 ALSA writer.
15
16 - Sideband connections: If both para_server and para_client
17 support this feature, data is sent as a multiplexed stream.
18 - The --no_default_filters option of para_filter has been
19 removed.
20 - Several fixes and latency improvements to various decoders.
21 - The ALSA writer now limits the prebuffer time to 500ms.
22 - Documentation improvements.
23 - Overhaul of the command_util.sh script.
24 - Fixes for some minor problems found by the clang analyzer.
25 - Compiles (almost) without warnings on gcc-3.
26 - Robustness improvements of the buffer tree code.
27
28 ------------------------------------------
29 0.4.10 (2012-03-30) "heterogeneous vacuum"
30 ------------------------------------------
31
32 Nothing earth-shaking in this release, but quite a few usability
33 improvements and the usual mix of cleanups and fixes.
34
35 - The --no_default_filters option of para_filter has been
36 deprecated. It still works but has no effect and will be
37 removed in the next version.
38 - para_gui now prints also the stderr output of the executing
39 command in the bottom window.
40 - Cleanup and consolidation of the various wrappers for
41 write(), writev(), send() and friends.
42 - The obscure error messages on mmap() failures have been
43 replaced by meaningful messages. This affects mainly
44 para_afh.
45 - para_audioc: Cleanups and memory leak fixes.
46 - Test 0004-server no longer fails if para_server is not
47 being built.
48 - New configure options: --with-id3tag-{headers,libs}.
49
50 -------------------------------------
51 0.4.9 (2011-12-06) "hybrid causality"
52 -------------------------------------
53
54 Support for another audio format, interactive mode for para_client
55 and para_audiod and many small improvements/fixes all over the place.
56
57 - Support for flac, the free lossless audio codec.
58 - Fix for an endless loop in the mp3 decoder for certain
59 (corrupt) mp3 files.
60 - When executed without specifying a command, para_client
61 and para_audioc start an interactive shell (requires
62 libreadline being installed). The interactive mode offers
63 full tab completion and command line history.
64 - autogen.sh now detects a distcc setup and adjusts the
65 parameter for the -j option of make accordingly.
66 - Shared memory areas are no longer restricted to 64K. We now
67 detect the maximal size of a shared memory area at runtime.
68 - cleanup of the internal uptime API.
69 - para_server prefaults the mmapped audio file to avoid
70 delays on slow media.
71 - A new test for the test-suite that exercises the
72 communication between para_server and para_audiod.
73 - The alsa writer eats up less CPU cycles when configured to
74 use the DMIX plugin.
75 - Simplified and unified receiver code.
76 - Makefile cleanups.
77 - Commands which print a list of matching audio files now
78 emit a meaningful error message if no audio file matched the
79 given pattern(s).
80
81 --------------------------------------
82 0.4.8 (2011-08-19) "nested assignment"
83 --------------------------------------
84
85 Gcrypt support, the overhauled osx writer and regex format specifiers
86 are the highlights of this release.
87
88 - support for libgcrypt as a drop-in replacement for openssl.
89 Run configure --enable-cryptolib=gcrypt to link against
90 libgcrypt. The two crypto implementations are compatible to
91 each other, i.e. a para_client executable linked against
92 gcrypt can connect to para_server linked against libssl
93 and vice versa.
94 - Rewrite of the osx writer (output plugin for Mac OS).
95 - audiod: The format specifier for receivers, filters and
96 writers is now treated as a regular expression. This allows
97 to replace 5 lines in the config file (one for each audio
98 format) by one single line. See the manual for details.
99 - The *.cmdline.[ch] files are no longer contained in the released
100 tarballs. This reduces the size of the tarballs but requires
101 gengetopt to build the tarball.
102 - Compiles cleanly also with llvm/clang.
103 - Corrupt mp3 files are handled more gracefully.
104 - The alsa writer uses poll fds instead of computing timeouts.
105 - Cleanup of the generic writer API.
106 - sched: Optimized zero timeouts.
107 - vss timeout cleanups.
108 - oggdec fixes and improvements.
109
110 --------------------------------------
111 0.4.7 (2011-06-01) "infinite rollback"
112 --------------------------------------
113
114 The new ao writer, support for ssh RSA keys and a couple of other
115 enhancements.
116
117 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
118 platforms through the libao audio library.
119 - Support for RSA keys generated with ssh-keygen.
120 - configure: improved options for ogg/vorbis/speex.
121 - The git version reported by --version always matches HEAD.
122 - The autogen script detects the number of processors and
123 runs a parallel make if possible.
124 - Major cleanup of the crypto API.
125 - Documentation updates.
126
127 ------------------------------------------
128 0.4.6 (2011-03-31) "deterministic entropy"
129 ------------------------------------------
130
131 Lots of ogg/vorbis improvements, the new test suite, enhancements
132 for para_gui and a fair amount of other bug fixes.
133
134 - For DCCP/OGG streams the audio file header is only sent once
135 at the beginning of the stream rather than periodically
136 every five seconds. This reduces network traffic and the
137 FEC group size.
138 - The vorbis comment header is replaced by an empty dummy header
139 before the header is sent over the network. This also results in
140 less network traffic and smaller FEC groups.
141 - The new "test" make target allows to perform some sanity checks prior
142 to installing the package.
143 - ogg timing fixes and performance improvements
144 - Scheduler improvements
145 - Proper exit codes for para_write
146 - para_gui: New option --theme to select a startup theme. Several
147 other improvements and fixes.
148 - aacdec error message cleanups
149 - simplified color error handling
150
151 --------------------------------------------
152 0.4.5 (2010-12-17) "symmetric randomization"
153 --------------------------------------------
154
155 Bug fixes, internal cleanups and variable-sized FEC slices.
156
157 - Contains a fix for an invalid-free-bug in the ogg audio format
158 handler code.
159 - Switching off the DCCP sender works again.
160 - para_audiod handles crashes of para_server more robustly.
161 - Internal scheduler and writer cleanups.
162 - Reduced latency due to variable-sized FEC slices.
163 - Improved documentation and error diagnostics.
164 - The build of para_server is now optional, allowing the build
165 to succeed in case libosl is not installed.
166
167 ------------------------------------------
168 0.4.4 (2010-08-06) "persistent regularity"
169 ------------------------------------------
170
171 Support for yet another audio format, para_write improvements and
172 bug fixes.
173
174 - Support for the speex codec.
175 - Support for sample formats other than 16 bit little endian.
176 - error2.h is now created by a perl script which speeds up configure
177 considerably.
178 - Fix a bug in the aac decoder which could lead to segfaults in
179 para_filter/para_audiod.
180 - Fixes for autoconf-2.66.
181
182 ----------------------------------------
183 0.4.3 (2010-07-05) "imaginary radiation"
184 ----------------------------------------
185
186 Many improvements for the DCCP and the UDP transport, the new user
187 manual and the usual mix of bug fixes and internal improvements.
188
189 - FEC support for the DCCP sender (Gerrit Renker). The new
190 --dccp_max_slice_size, --dccp_data_slices_per_group and
191 --dccp_slices_per_group options can be used to set the FEC
192 parameters for the DCCP transport.
193 - DNS lookups for UDP targets (Gerrit Renker).
194 - The new user manual replaces the README, README.afs, REQUIREMENTS
195 and INSTALL documents.
196 - Fix an end-of-file detection bug in the oggdec filter.
197 - The new nonblock API.
198 - Both options of the oggdec filter have been removed.
199 - New debug mode for the internal scheduler.
200
201 ------------------------------------------
202 0.4.2 (2010-04-23) "associative expansion"
203 ------------------------------------------
204
205 It's been some time since the last release, but finally here is
206 paraslash-0.4.2. The bulk of the changes comes from the new buffer
207 tree API, but there are changes all over the tree. Mainly performance
208 and usability improvements, but also quite some bug fixes.
209
210 - The new buffer tree API.
211 - DCCP: Support for CCID negotiation (Gerrit Renker).
212 - UDP robustness fixes.
213 - The --bufsize option for mp3dec is gone as it no longer makes sense
214 for the new buffer tree API.
215 - Fix audible buffer underruns for wma streams.
216 - The alsa writer no longer prints meaningless underrun durations.
217 - audiod: Defaults work also for udp streams. If no filter is
218 given for an audio format that is received via upd, fecdec is
219 automatically added as the first filter (along with the decoder).
220
221 ---------------------------------------
222 0.4.1 (2009-12-22) "concurrent horizon"
223 ---------------------------------------
224
225 Support for another audio format, minor feature enhancements and lots of bug
226 fixes. All fixes that have been accumulated in the maint branch (in particular
227 those mentionened in the 0.3.6 release notes) appear in this release as well.
228
229 - wma support.
230 - new afh option: --human to activate human-readable output.
231 - new server/audiod option: --log-timing to print timing information.
232 - build system improvements.
233 - source code documentation updates.
234
235 -------------------------------------
236 0.3.6 (2009-12-07) "cubic continuity"
237 -------------------------------------
238
239 Quite a few bugs have been found and fixed since 0.3.5, so here's
240 another 0.3.x release. No new features.
241
242 - Always check return value of malloc().
243 - ogg vorbis/FEC: Do not write garbage after the audio file header.
244 - exit if root privileges could not be dropped.
245 - FEC: Fix computation of extra slices.
246 - oss: Fix check for empty input buffer.
247 - Avoid buffer underruns due to filter chain output buffer constraints.
248 - server: Fix assignment of afs_pid.
249 - Don't panic if the afs database contains unknown audio formats.
250 - http/dccp: Do not send the audio file header twice.
251 - FEC: Timing improvements.
252
253 ----------------------------------------------
254 0.4.0 (2009-11-10) "simultaneous independence"
255 ----------------------------------------------
256
257 Two significant changes which require the new version number: The
258 improved authentication dialog and the fact that the database code
259 has been moved to a library, libosl. To use the new version, you have
260 to generate new RSA keys, see INSTALL for details. A shell script is
261 provided for conversion of the 0.3 database to the new 0.4 format.
262
263 - stronger crypto for client authentication
264 - the database code has been moved to a library
265 - improved status item handling
266 - cleanup of the build system
267 - The "-V" option now also prints the git version
268 - the new parser-friendly listing mode for the ls and stat commands
269 - mandatory rc4 encryption
270 - major audio format handler cleanups
271 - (id3,...) tags are no longer stored as a combined string in the database
272 - new mood methods: artist_matches, title_matches, comment_matches,
273 album_matches, year_maches, year.
274
275 --------------------------------------------
276 0.3.5 (2009-09-21) "symplectic separability"
277 --------------------------------------------
278
279 Full client support for *BSD Unixes, complete re-write of the ogg
280 vorbis audio format handler, various improvements all over the place
281 and the usual mix of bugfixes. This release marks the end of the 0.3
282 series if no serious problems show up.
283
284 - the new oss writer (supported on *BSD and Linux)
285 - rewrite of the ogg vorbis audio format handler. It's
286 recommended to replace the chunk tables of existing ogg
287 vorbis files in the afs database by re-adding these files
288 with "add -f".
289 - support for netmask subsets (Gerrit Renker)
290 - the new prebuffer filter
291 - improved signal handling
292 - variable fec output buffer size
293 - improved FEC timing fixes audible buffer underruns in UDP mode
294 - --log_color actually works
295 - new ls option: -d (print dates as seconds after the epoch)
296 - update to gengetopt 2.22.2
297 - support for RSA keys of size > 512 bits
298 - new option "mixer_channel" for para_fade
299
300 -----------------------------------------
301 0.3.4 (2009-05-07) "elliptic inheritance"
302 -----------------------------------------
303
304 The new udp sender, forward error correction, colored logs and various
305 other improvements. As the udp sender does not depend on any special
306 libraries, it is built unconditionally.
307
308 - The udp sender replaces the ortp sender. The new code uses forward
309 error correction to protect against packet losses. Many thanks to
310 Gerrit Renker for providing ipv6 support.
311 - The default port for udp streaming now defaults to 8000, like
312 for the http and the dccp senders/receivers.
313 - Loglevels are now specified as symbolic names, e.g.
314 "--loglevel info".
315 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
316 - para_server/para_audiod: Color support for log messages.
317 - new options for mp3dec: --ignore-crc, --bufsize
318 - new audiod option: --config-file.
319 - gengetopt cleanups.
320 - Improved help/man pages: The documentation of para_audiod,
321 para_recv, para_filter and para_write now also contains
322 all options of the available receivers/filters/writers. The
323 man page of para_fade contains a description of the different
324 modes of operation.
325 - More source code documentation.
326 - vss timing fixes.
327
328 --------------------------------------------
329 0.3.3 (2008-12-01) "axiomatic perspectivity"
330 --------------------------------------------
331
332 Internal code cleanups, bug fixes, improved tag handling and the new
333 amplification filter.
334
335 - para_server uses the generic scheduling code.
336 - overhaul of the virtual streaming system.
337 - mp3: id3 version 2 support via libid3tag (optional)
338 - ogg: vorbis comment support.
339 - aac meta info support.
340 - mp3 audio format handler cleanups.
341 - new filter: "amp" to amplify the amplitude of the audio stream
342 - new status item/database entry: amplification. It is
343 used by the amp filter to pre-amplify the audio stream.
344 - fix a close-without-open bug in para_write.
345 - fix a bug in com_init() which was introduced in 0.3.2.
346 - better error diagnostics for para_client.
347
348 -----------------------------------------
349 0.3.2 (2008-04-11) "probabilistic parity"
350 -----------------------------------------
351
352 The new para_afh executable, scheduling and documentation improvements.
353
354 - new ls option: -lc (list chunk table)
355 - new executable: para_afh, the stand-alone audio file handler tool
356 - afs commands can send output more than SHMMAX (32MB on Linux). This
357 also reduces the memory usage of commands that produce large amounts
358 of output.
359 - major scheduler and audiod cleanups.
360 - more detailed and much nicer man pages.
361
362 ---------------------------------------
363 0.3.1 (2008-02-23) "liquid interaction"
364 ---------------------------------------
365
366 A mix of cleanups, bug fixes, improvements, and some new features. No
367 significant changes to the new database (osl) code, which is generally
368 a good sign.
369
370 - Share some similar/duplicate code between the http and the
371 dccp sender.
372 - Generic access control lists for paraslash senders.
373 - dccp sender: Access control lists, connection limiting and support
374 for the allow,deny,on,off,help sender commands.
375 - The default dccp port changed from 5001 to 8000 (suggested by
376 Gerrit Renker).
377 - para_server starts even if not all public keys could be loaded.
378 - Audiod performance improvements.
379 - fix a bug in the "off" command of the http sender.
380 - fix some fd and memory leaks.
381 - Update to gengetopt-2.22.
382
383 -------------------------------------
384 0.3.0 (2008-01-12) "solar saturation"
385 -------------------------------------
386
387 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
388
389
390 Usually one might expect lots of new features AND a big increase in size
391 for a major release like this.
392
393 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
394 ever. The decrease in size is mostly due to the removal of some
395 graphical tools (which were only quick hacks anyway). But also the
396 fact that the mysql code is gone cuts down the size a bit.
397
398 Being independent of mysql comes at a cost: The fact that paraslash
399 now contains its own database (the object storage layer, osl) increases
400 the (stripped) binary size of para_server by ~50K on i386.
401
402 - no more restrictions on unique basenames.
403 - independent of mysql: The new self-contained object
404 storage layer (osl) replaces the mysql database.
405 - New executable para_fsck: Check integrity of osl tables.
406 - Lyrics support.
407 - Reliable audio file move/rename detection.
408 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
409 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
410 Solaris (sparc64).
411 - the new osl-based audio file selector (afs) replaces the random,
412 the playlist and the mysql selector of paraslash-0.2.x.
413 - IPv6 support (thanks to Gerrit Renker).
414 - paraslash-0.2.x streams are now called "moods". Writing
415 0.3.x-mood definitions should be both easier and more
416 powerful than writing 0.2.x-stream definitions.
417 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
418 been removed. The world is a better place without them. However,
419 para_gui is still there.
420 - afs tracks audio file selection also in playlist mode.
421 - few easy-to-use afs commands replace the many not-so-easy-to-use
422 mysql commands (and are available also in playlist mode).
423 - Improved error subsystem.
424 - The earth-shaking new logo.
425
426 -----------------------------------------
427 0.2.17 (2007-11-20) "isotropic threshold"
428 -----------------------------------------
429
430 Mainly bugfixes and cleanups in this version which marks the end of
431 the 0.2.x series if no serious bugs show up after the release.
432
433 - mysql_selector: fix a locking bug.
434 - universal chunk queueing.
435 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
436 to Gerrit Renker).
437 - be more carful wrt. signed vs. unsigned argument passing.
438 - cleanup error.h and fix some references to invalid error
439 codes.
440 - update to gengetopt-2.21.
441 - update to ortp-0.13.1.
442 - autoconf: extend checks for headers, library functions and
443 compiler characteristics.
444 - Fix streaming of large mp3 files.
445 - Fix an off-by-one bug in playlist handling.
446
447 --------------------------------------
448 0.2.16 (2007-04-05) "neural discharge"
449 --------------------------------------
450
451 The main change in this release is the major audio format handler
452 cleanup which removes some similar/duplicate code and makes it easier
453 to implement plugins for other audio formats. Of course, the usual mix
454 of other improvements/changes/bugfixes also made it into the release.
455
456 - simplified audio format handlers (most of the handling functions
457 were moved one layer up to the virtual streaming system).
458 - para_server uses mmap to read audio files
459 - repositioning of mp3 streams is much faster, in particular for
460 jumping near the end of large mp3 files.
461 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
462 and AFS_WRITE.
463 - fix a bug in para_filter that caused decoding of aac files
464 to start only after a few seconds.
465 - fix osx_writer hangs
466 - simplified dccp code (thanks to Gerrit Renker)
467 - the compress filter works also on big endian systems (ppc)
468
469 -----------------------------------------
470 0.2.15 (2007-02-16) "inductive resonance"
471 -----------------------------------------
472
473 Minor improvements, more documentation and a bunch of bug fixes.
474
475 - para_server: The server.users file is only read once on server
476 startup rather than for each connection
477 - mp3dec: Fix decoding of corrupt mp3 files
478 - afs (audio file sender) is now called vss (virtual streaming
479 system). Consequently, the permission flags specified in
480 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
481 become VSS_READ and VSS_WRITE respectively.
482 - para_audiod/para_filter: Fix a bug that caused the last chunk
483 of audio data not being written under certain circumstances
484 - audiod: compute the difference of server time and local time
485 correctly
486 - para_server/para_audiod: Fix some memory leaks
487 - documentation improvements
488 - configure.ac: fix checks for para_krell
489 - new man pages
490
491 -------------------------------------------
492 0.2.14 (2006-10-15) "transient singularity"
493 -------------------------------------------
494
495 The only major enhancement of this version is the osx writer which completes
496 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
497 until now for reasons beyond the scope of this changelog entry.
498
499 - new output plugin for Mac Os: the osx writer
500 - rename configure command line options from --enable-xxx-headers to
501 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
502 - configure: new command line options: --with-mad-headers,
503 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
504 - some robustness fixes
505 - dymamic audio format recognition for audiod
506 - para_server: new command line option: --autoplay_delay
507 - para_audiod: new command line option: --clock_diff_count
508
509 ---------------------------------------
510 0.2.13 (2006-07-14) "sonic convolution"
511 ---------------------------------------
512
513 A bunch of new features and core changes.
514
515 - the new paraslash scheduler, short and sweet.
516 - Support for m4a/mp4 files via the new aac audio format
517 handler/filter (requires libfaad).
518 - each writer has its own command line parser, just like
519 para_recv and para_filter.
520 - para_client and para_audioc use the error subsystem
521 - writers are integrated in para_audiod (currently linux-only)
522 - para_client is integrated in para_audiod
523 - random/playlist selector: improved info strings
524 - new audiod commands: tasks, kill
525 - update to libortp-0.10.1
526 - para_fade: wake time defaults to 8 hours from now
527 - update to autoconf-2.60
528
529 ------------------------------------------
530 0.2.12 (2006-05-12) "oriented abstraction"
531 ------------------------------------------
532
533 Many user-visible changes in this release and lots of new
534 features:
535
536
537 - the new optional dccp sender/receiver. It uses the datagram
538 congestion control protocol. You'll need a fairly new kernel
539 for this.
540 - paraslash works on Mac OS X (thanks to Gerd Becker)
541 - para_play renamed to para_write
542 - modular output plugin design (writers) for para_write
543 - new file_writer output plugin for para_write
544 - compress filter speed improvements
545 - update to libortp-0.9.1
546 - update to gengetopt-2.17rc
547 - para_client no longer depends on libreadline (as the
548 code for the interactive mode was removed).
549 - gcc-2-95 is no longer a supported compiler. It may still
550 work, but it gets no more testing.
551 - the tarball no longer contains the screenshot images which
552 reduces its size quite a bit.
553 - configure: new command line options: --enable-mysql-headers
554 and --enable-mysql-libs
555
556 ------------------------------------
557 0.2.11 (2006-03-11) "atomic duality"
558 ------------------------------------
559
560 Here it is, the first paraslash release developed with git. There
561 are fairly many user-visible changes in this release. As two out of
562 the three "database tools" of paraslash don't use a database at all,
563 they are now called "audio file selectors" instead.
564
565
566 - the cdt command (change database tool) becomes chs (change
567 selector)
568 - no more colon separators: The syntax of some options of
569 para_audiod and para_filter have changed. Use --help for
570 more info (and some examples).
571 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
572 - switch from cvs to git (should've done that earlier)
573 - the new ipc subsystem
574 - new audio file selector: playlist
575 - para_server: the dopey selector is now called "random",
576 and is the default selector. Use the --selector option to
577 choose another selector at startup, or the chs command to
578 change the selector at runtime.
579 - X86_64 fixes (thanks to Steffen Klassert)
580 - para_play fixes
581
582 --------------------------------------
583 0.2.10 (2006-02-17) "cyclic attractor"
584 --------------------------------------
585
586 Huge documentation update, a scrollable window for para_gui, ortp
587 improvements, and of course many small fixes not mentioned here.
588 The diffstat below is rather misleading as most insertions are due
589 to the new source documentation.
590
591 - autoconf cleanup
592 - para_server also uses the new error subsystem
593 - lots of new documentation (UTSL)
594 - gui improvements:
595 - keysyms for cursor keys and for next/previous page keys
596 - scrollable output window
597 - new internal commands: scroll up/down, page up/down
598 - fix color of command output.
599 - ortp: the --chunk_time and --header flags are no longer needed
600 for para_recv/para_audiod as this information is now encoded in
601 each rtp packet sent by para_server.
602
603 -------------------------------------------
604 0.2.9 (2006-01-24) "progressive turbulence"
605 -------------------------------------------
606
607 Internal audiod receivers/filters, the new error subsystem and
608 a lot of small improvements.
609
610 - para_recv and para_filter are integrated into the para_audiod
611 binary, i.e. audiod no longer spawns a new process for
612 each receiver/filter. As para_recv and para_filter might be
613 useful as standalone programs, they still get built (linked
614 against the same object files that are also used for audiod).
615 - further ortp timing improvements should reduce the CPU usage
616 of the ortp receiver.
617 - improved audio grabbing. The 'grab' command of para_audiod
618 has its own set of command line options. Read the output of
619 "para_audioc help grab" for more info.
620 - oggdec: configurable input prebuffer size.
621 - the new error subsystem gives better error diagnostics
622 and reduces code size.
623
624 -----------------------------------------
625 0.2.8 (2006-01-02) "dynamic accumulation"
626 -----------------------------------------
627
628 The new modular filter design and the para_play-hangs bugfix.
629
630 - new executable: para_filter. It combines para_mp3dec,
631 para_oggdec and para_compress. It also adds a further filter
632 type, wav, that just inserts a wave header at the desired point
633 of the filter chain. All 'piping' is done in-memory (i.e. no
634 read/write operations are used).
635 - para_play: fix a stupid bug that caused it to hang under
636 certain circumstances.
637
638 -------------------------------------------
639 0.2.7 (2006-12-27) "transparent invariance"
640 -------------------------------------------
641
642 Not many user-visible changes but a fair amount of internal improvements.
643
644
645 - The http sender buffers data if it can not be sent
646 out immediately (because the socket is not writable). This
647 should prevent para_server from shutting down the connection
648 too early on a loaded network.
649 - para_play also prebuffers data if it is told to start at a
650 future time by the --start_time option.
651 - The return of para_recv: It combines para_ortp_recv and
652 para_http_recv. Use the --receiver option to switch between
653 the two. para_recv builds without libortp, but contains
654 only the http receiver in this case.
655 - update to ortp 0.8.1. As this ortp release contains incompatible
656 changes, para_recv-0.2.7 won't link against older ortp libs.
657 - improved ortp timings.
658 - use of gcc-extensions that #define away for non-gcc and
659 gcc < 3.0.
660
661 -------------------------------------------
662 0.2.6 (2005-10-29) "recursive compensation"
663 -------------------------------------------
664
665 Transparent session encryption (uses openssl's Alleged RC4 cipher),
666 the internal find command and several other improvements and cleanups.
667
668 - Encrypt the session if encryption is requested by the client
669 (default for para_client 0.2.6). This is backwards
670 compatible, so older clients can still connect to para_server
671 0.2.6. Use the new client option --plain to request an
672 uncrypted session (off by default, must be set to on in
673 order to connect to para_server 0.2.x with 0 <= x <= 5).
674 - para_server uses an internal function to locate audio files
675 rather than calling find(1). The server option
676 --mysql_audio_file_dir replaces --mysql_find_cmd.
677 - documentation update
678 - man pages
679 - header file cleanup
680 - para_client code cleanup
681 - para_gui: faster display of output of display commands
682
683 ------------------------------------------
684 0.2.5 (2005-10-13) "aggressive resolution"
685 ------------------------------------------
686
687 This release adds internal senders, i.e. no more external programs are
688 spawned for sending out the audio data. There are two different senders
689 available: The http sender and the ortp sender (former para_send which
690 is no longer needed).
691
692 The new sender code has a plugin-like design so it can be easily
693 extended should there be be any future need for supporting another
694 network streaming protocol. All senders are completely independent of
695 each other. In particular, the http and the ortp sender can operate
696 in parallel.
697
698 - new server command: sender to control senders at runtime.
699 Read the output of "para_server -h" and "para_client help
700 sender" for more information.
701 - para_recv renamed to para_ortp_recv
702 - new executable: para_http_recv, a simple command line
703 http receiver.
704 - major afs/mp3/ogg code simplifications due to internal
705 senders.
706 - ogg timing improvements
707 - fix several minor memory leaks (found by valgrind)
708 - empty stream definitions work again
709 - com_ne(): ignore errors on remove
710 - audiod: fix segfault on server restart
711
712 ---------------------------------------
713 0.2.4 (2005-09-21) "toxic anticipation"
714 ---------------------------------------
715
716 Several small improvements, fixes and the new grab command.
717
718 - audiod:
719 - new command: "grab" to grab the output of the stream reader
720 or any filters. Read the output of "para_audioc help grab"
721 for more information.
722 - fix memory leak
723 - code cleanup
724 - audioc: new command line option: --bufsize to specify a
725 buffer size different from the default size 8192.
726 - improved error diagnostics for para_play.
727 - new configure option: --enable-ssldir so search for openssl in
728 non-standard places
729 - sdl_gui: Make it look nice again for 1024x768
730 - server: report total size of memory allocated with sbrk by malloc,
731 new command line option: --announce_time
732
733 -----------------------------------------
734 0.2.3 (2005-09-01) "hydrophilic movement"
735 -----------------------------------------
736
737 Two new executables and major feature enhancements.
738
739 - audiod filters: It is now possible to specify arbitrary many
740 (including none) filters for each supported audio
741 format. This can be used e.g. for normalizing volume,
742 transforming or grabbing the audio stream, or for using
743 visualizers. Read the output of "para_audiod -h" for the
744 syntax of the new --filter_cmd option.
745 - new executable: para_play, a tiny alsa player. It
746 can play wave files or raw pcm (16 bit little endian)
747 from stdin.
748 - new executable: para_compress, a dynamic range compressor
749 intended to keep audio output at a consistent volume. Derived
750 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
751 - audiod: New option: --stream_delay. This can be used in
752 a local network to syncronize the audio output of all
753 clients that play the same stream.
754
755 ------------------------------------------
756 0.2.2 (2005-08-19) "tangential excitation"
757 ------------------------------------------
758
759 Mostly internal changes in this release, but also some new commands
760 for the mysql database tool.
761
762 - cleanup exec.c, fix para_exec bug
763 - compile time loglevel (log messages below the given level
764 won't be compiled in, which reduces the size of the
765 resulting binaries)
766 - new log macros that shorten the size of the source code.
767 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
768 to send only zeros. With this workaround, para_audioc works
769 again.
770 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
771 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
772 (new entry), "snp" (set numplayed). Read the manual for more
773 information.
774
775 ---------------------------------------
776 0.2.1 (2005-08-15) "surreal experience"
777 ---------------------------------------
778
779 Here comes paraslash-0.2.1. It contains a couple of new features and,
780 surprise, only minor bug fixes.
781
782 - kill noisy mp3 debug message
783 - cleanup of the build system
784 - para_server and para_client directly use the crypto routines
785 of the openssl library rather than invoking the openssl command
786 line utitlity
787 - server/audiod: new option --user to switch to the given user
788 when invoked as root. Read the output of "para_server -h" for
789 more information.
790 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
791 status. Default: "para_audioc stat"
792 - sdl_gui: new option --pic_cmd to be used to download the picture.
793 Default: "para_client pic"
794 - audiod: 5 slots ought to be enough for everybody
795 - audiod: new status item: Uptime, kill hup command
796
797 ------------------------------------------
798 0.2.0 (2005-08-06) "distributed diffusion"
799 ------------------------------------------
800
801 After several month of increased development activity, paraslash-0.2.0
802 has arrived. It contains many new features and is much more
803 self-contained than the old 0.1.x series. Enjoy!
804
805
806 - para_server: fix hang on song change and crash on sighup.
807 Speed up mysql queries. The DIR_LIKE macro is gone.
808 - new executables: para_audiod, the local audio daemon that
809 starts playback (uses SCM_CREDENTIALS socket magic) and
810 para_audioc, the corresponding client.
811 - new executables: para_mp3dec/para_oggdec, two really teensy
812 decoders. para_mp3dec is based on libmad, para_oggdec requires
813 libvorbisfile.
814 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
815 they are now called para_send and para_recv respectively.
816 - documentation updates
817 - para_gui is themable. For now there is the default theme that
818 looks as before and the simple theme: blue and easy.
819 - gui: audio streaming is now handled by audiod. Time display shows
820 playback time rather than streaming time
821 - slider: update to libzmw-0.2.0
822 - para_krell: fix crash on server shutdown
823 - switch from gzip to bzip2
824
825 ----------------------------------------
826 0.1.7 (2005-04-18) "melting penetration"
827 ----------------------------------------
828
829 The main change in this release is clearly the oggvorbis rewrite,
830 but there are also lots of smaller changes. If you intend to use both
831 the mp3 and the ogg plugin, it is recommended to use software mixing,
832 e.g. the dmix plugin which is provided by ALSA.
833
834 - new executables: para_ovsend and para_ovrecv for sending/receiving
835 oggvorbis files via rtp. Requires the open rtp library. Get it at
836 http://www.linphone.org/ortp/
837 - rewrite of the ogg_vorbis core code
838 - configure detects libzmw and, if detected, includes
839 para_slider to the list of binaries to be built by make
840 - server stream writers read from their associated fifo rather
841 than from stdin
842 - slider: two new sliders, lastplayed and numplayed
843 - fix nasty double free bug which caused random segfaults in case of
844 mp3 files with invalid header information
845 - gui: new command line option: --stream_timeout=seconds to
846 deactivate a slot if it is idle for that many seconds (default=`5')
847 - diffstats
848
849 ---------------------------------------
850 0.1.6 (2005-03-05) "asymptotic balance"
851 ---------------------------------------
852
853 Only little user-visible changes in this release. Mainly bugfixes and
854 core code cleanup. This is probably the most stable version ever if you
855 stick to mp3...
856
857 - fix several memory leaks
858 - rename default name of mysql database from "music" to "paraslash".
859 Use para_server's --mysql_database option if you do not want to
860 rename your old database.
861 - rework ogg vorbis code
862 - make update command work on mysql servers with LOCAL_INFILE
863 disabled
864 - gui: improved stream I/O (slots)
865 - simplified audio format API
866 - para_pob_ogg is gone
867
868 ------------------------------------
869 0.1.5 (2004-12-31) "opaque eternity"
870 ------------------------------------
871
872 Let's slide gently into the new year.
873
874 - new: para_slider (not built automatically, type "make
875 para_slider" to build). A toy for those who always felt that
876 creating stream definitions is difficult. See screenshots,
877 README and FEATURES for more info.
878 - improved signal handling. Fixes server segfault on SIGHUP
879 for linux kernels newer than Aug 24 2004 and makes para_gui
880 race-free.
881 - reload database tool on SIGHUP
882 - improved help message for sl
883 - do not log "broken pipe" messages as errors. They are
884 perfectly ok.
885 - fix wrong error message on permission errors
886
887 -----------------------------------------
888 0.1.4 (2004-12-19) "tunneling transition"
889 -----------------------------------------
890
891 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
892 Hopefully, most of them got wiped out with this release. Some
893 enhancements went also in.
894
895 - improved error diagnostics for all commands
896 - stradd/picadd: overwrite previous contents if entry already
897 exists, rather than returning errors
898 - stradd: use current stream if invoked without args
899 - faster (and hopefully more stable) ogg-vorbis handling
900 - para_krell: reap children to avoid zombie-flooding in case
901 no server is running
902 - si: report also server pid
903 - server: don't busy-loop if dbtool reports only invalid files.
904 - gui: CTRL+C works again, fix stream_read command line option
905 - fix pic_add, hist
906 - fix mysql dbtool startup in case no database exists
907 - many small fixes and cleanups
908
909 ---------------------------------------
910 0.1.3: (2004-12-10) "vanishing inertia"
911 ---------------------------------------
912
913 Starting from this release, the database tools are integrated in the
914 server binary. This decreases server startup time, reduces code size
915 and speeds up database commands. However, the layout of the underlying
916 mysql database changed only slightly and 0.1.3 should be backwards
917 compatible in that respect.
918
919 Visible changes:
920
921 - If mysql is not detected at compile time, or fails to init
922 at runtime, fall back to the dopey database tool which should
923 always work.
924 - para_dbtool and dbtool.conf are gone. All mysql specific
925 options are read from server.conf and are prefixed by 'mysql_'.
926 - new command: cdt (change database tool)
927 - new command line option: dbtool (choose startup database tool)
928 - The name of current stream is now stored in the database,
929 so paraslash remembers its current stream when restarted.
930 - new command: csp (change stream and play)
931 - para_gui also reports current database tool and server uptime
932
933 -------------------------------------------
934 0.1.2: (2004-11-28) "spherical fluctuation"
935 -------------------------------------------
936
937 Point release before the big dbtool changes go in.
938
939 - dbtool: rename ca to cam (copy all meta data). It now also
940 copies numplayed and lastplayed time as well as the picture
941 id.
942 - fix endless-loop-bug caused by mp3 files with invalid header
943
944 -----------------------------------------
945 0.1.1: (2004-11-05) "floating atmosphere"
946 -----------------------------------------
947
948 - gkrellm plugin
949 - new dbtool command: mbox. Browse your sound-file collection
950 with your favorite mail reader.
951 - several small fixes
952
953 -------------------------------------
954 0.1.0: (2004-10-22) "rotating cortex"
955 -------------------------------------
956
957 - fix logging bug for loglevel > VERBOSE
958 - fix skip command
959 - correct timings for vbr mp3s
960 - modular audio format support
961 - ogg-vorbis support (experimental)
962 - new server option: autoplay
963
964 -----------------------------------------
965 0.0.99: (2004-07-25) "harmonic deviation"
966 -----------------------------------------
967
968 - rename projectname from icc to paraslash (play, archive, rate
969 and stream large audio sets happily)
970 - paraslash is no longer restricted to one particular audio
971 streaming software
972 - new dbtool commands (stradd, strq, strdel) for easy stream
973 managment w/o configuration file. That obsoletes stream_defs
974 file/config option for dbtool.
975 - picadd accepts jpeg data from stdin
976 - new server commands: ps (select previous stream), sc (song change)
977 - new default pictures for sdl_gui
978 - gui: new key_map option for binding commands and internal
979 functions to arbitrary keys, nice help screen, rip out
980 soundcard/linux specific stuff, avoid noise artefacts while jumping,
981 show silly logo on startup
982 - new executables: para_fade for fading volume, para_dbadm for
983 manipulating attributes
984 - cdb adds _all_ tables to mysql database
985 - revised and beautified documentation
986 - sample dbtool rewritten in C
987 - autoconf
988
989 ---------------------------------------------
990 0.0.98: (2003-12-26) "incremental smoothness"
991 ---------------------------------------------
992
993 - kick icecast in favour of poc. That removes some races and reduces
994 core code considerably.
995 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
996 give finer info on afs' status.
997 - gui can start decoder (see config options). Further new gui
998 commands: refresh (^L), jmp (F1-F10)
999 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1000 terminates gui. This fixes dead instances consuming memory
1001 continuously.
1002 - new dbtool command: verb for sending verbatim sql queries.
1003 - fix pid_list races (by removing pid_list)
1004 - codename funnies
1005
1006 --------------------
1007 0.0.97: (2003-10-26)
1008 --------------------
1009
1010 - installation prefix now defaults to /usr/local
1011 - new commands for gui: snozze, sleep and reread config
1012 - config file for gui and sdl_gui
1013 - fix problems with filenames containing funny characters
1014 (reported by Thomas Forell)
1015 - improved signal handling for gui, now it rereads conf on SIGHUP
1016 - new dbtool command: cdb (create database)
1017 - switch from argtable to gengetopt
1018 - major code cleanup and speed improvements
1019 - fix several potential buffer overflows
1020 - many small fixes and cleanups
1021
1022 -------------------
1023 0.0.96 (2003-08-30)
1024 -------------------
1025
1026 - easy stream_defs syntax
1027 - sdl_gui can display images associated to the file being played
1028 - Major feature enhancements for icc_gui including dynamic text
1029 placement and the top/bottom window design
1030 - vrfy/clean now also checks for NULL values in attributes as
1031 well as for invalid picture pointers
1032 - fix long outstanding case sensitivity bug
1033 - many small fixes and cleanups
1034
1035 -------------------
1036 0.0.95 (2003-06-29)
1037 -------------------
1038
1039 - sdl gui runs much faster
1040 - new dbtool command: ca (copy attributes)
1041 - count and display number of times the song has been played
1042 - new feature: scoring
1043 - command line options for sdl_gui
1044 - simpler syntax of streams file
1045 - decrease network traffic of stat
1046 - fix zombie bug
1047 - many small fixes and cleanups
1048
1049 -------------------
1050 0.0.94 (2003-05-04)
1051 -------------------
1052
1053 - new server command: ns (next stream)
1054 - new icc_gui command: c (change stream)
1055 - internal mp3info
1056 - stat shows also id3 tag info
1057 - new sdl based gui
