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

1016 well as for invalid picture pointers
1017 - fix long outstanding case sensitivity bug
1018 - many small fixes and cleanups
1019
1020 -------------------

1026 - count and display number of times the song has been played
1027 - new feature: scoring
1028 - command line options for sdl_gui
1029 - simpler syntax of streams file
1030 - decrease network traffic of stat
1031 - fix zombie bug
1032 - many small fixes and cleanups
1033
1034 -------------------
1035 0.0.94 (2003-05-04)
1036 -------------------
1037
1038 - new server command: ns (next stream)

1044 - many small fixes and cleanups
1045
1046 -------------------
1047 0.0.93 (2003-03-28)
1048 -------------------
1049
1050 - colors for icc_gui
1051 - icc_gui sets volume directly (linux only)
1052 - proper locking that fixes some races
1053 - fix security bug that caused commands to be executed even
1054 with unsufficient permissions
1055 - new command: hup to make all servers reread their configuration file
1056 - icecast meta data streaming
1057 - many small fixes and cleanups
