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

965 well as for invalid picture pointers
966 - fix long outstanding case sensitivity bug
967 - many small fixes and cleanups
968
969 -------------------
970 0.0.95 (2003-06-29)
971 -------------------

997 -------------------
998
999 - colors for icc_gui
1000 - icc_gui sets volume directly (linux only)
1001 - proper locking that fixes some races
1002 - fix security bug that caused commands to be executed even
1003 with unsufficient permissions
1004 - new command: hup to make all servers reread their configuration file
