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

985 well as for invalid picture pointers
986 - fix long outstanding case sensitivity bug
987 - many small fixes and cleanups
988
989 -------------------

999 - decrease network traffic of stat
1000 - fix zombie bug
1001 - many small fixes and cleanups
1002
1003 -------------------

1015 -------------------
1016 0.0.93 (2003-03-28)
1017 -------------------
1018
1019 - colors for icc_gui
1020 - icc_gui sets volume directly (linux only)
1021 - proper locking that fixes some races
1022 - fix security bug that caused commands to be executed even
1023 with unsufficient permissions
1024 - new command: hup to make all servers reread their configuration file
1025 - icecast meta data streaming
1026 - many small fixes and cleanups
