1 ---------------------------------------------
2 0.?.? (to be announced) "volatile relativity"
3 ---------------------------------------------
5 - The "versions" directory has been removed from the master
6 branch. The tarballs of the old releases are now available
7 in the new "releases" branch.
8 - Overhaul of the build system: All generated files are now
9 written to the "build" directory.
11 --------------------------------------
12 0.4.11 (2012-07-20) "mutual diversity"
13 --------------------------------------
15 The major feature in this release is the new sideband API for
16 client-server communication. This API will be used exclusively starting
17 with 0.5.0, which breaks backward compatibility but allows to get rid
18 of quite some compatibility code. Other noteworthy changes include
19 decoder latency improvements and a long-standing bug fix for the
22 - Sideband connections: If both para_server and para_client
23 support this feature, data is sent as a multiplexed stream.
24 - The --no_default_filters option of para_filter has been
26 - Several fixes and latency improvements to various decoders.
27 - The ALSA writer now limits the prebuffer time to 500ms.
28 - Documentation improvements.
29 - Overhaul of the command_util.sh script.
30 - Fixes for some minor problems found by the clang analyzer.
31 - Compiles (almost) without warnings on gcc-3.
32 - Robustness improvements of the buffer tree code.
34 ------------------------------------------
35 0.4.10 (2012-03-30) "heterogeneous vacuum"
36 ------------------------------------------
38 Nothing earth-shaking in this release, but quite a few usability
39 improvements and the usual mix of cleanups and fixes.
41 - The --no_default_filters option of para_filter has been
42 deprecated. It still works but has no effect and will be
43 removed in the next version.
44 - para_gui now prints also the stderr output of the executing
45 command in the bottom window.
46 - Cleanup and consolidation of the various wrappers for
47 write(), writev(), send() and friends.
48 - The obscure error messages on mmap() failures have been
49 replaced by meaningful messages. This affects mainly
51 - para_audioc: Cleanups and memory leak fixes.
52 - Test 0004-server no longer fails if para_server is not
54 - New configure options: --with-id3tag-{headers,libs}.
56 -------------------------------------
57 0.4.9 (2011-12-06) "hybrid causality"
58 -------------------------------------
60 Support for another audio format, interactive mode for para_client
61 and para_audiod and many small improvements/fixes all over the place.
63 - Support for flac, the free lossless audio codec.
64 - Fix for an endless loop in the mp3 decoder for certain
66 - When executed without specifying a command, para_client
67 and para_audioc start an interactive shell (requires
68 libreadline being installed). The interactive mode offers
69 full tab completion and command line history.
70 - autogen.sh now detects a distcc setup and adjusts the
71 parameter for the -j option of make accordingly.
72 - Shared memory areas are no longer restricted to 64K. We now
73 detect the maximal size of a shared memory area at runtime.
74 - cleanup of the internal uptime API.
75 - para_server prefaults the mmapped audio file to avoid
77 - A new test for the test-suite that exercises the
78 communication between para_server and para_audiod.
79 - The alsa writer eats up less CPU cycles when configured to
81 - Simplified and unified receiver code.
83 - Commands which print a list of matching audio files now
84 emit a meaningful error message if no audio file matched the
87 --------------------------------------
88 0.4.8 (2011-08-19) "nested assignment"
89 --------------------------------------
91 Gcrypt support, the overhauled osx writer and regex format specifiers
92 are the highlights of this release.
94 - support for libgcrypt as a drop-in replacement for openssl.
95 Run configure --enable-cryptolib=gcrypt to link against
96 libgcrypt. The two crypto implementations are compatible to
97 each other, i.e. a para_client executable linked against
98 gcrypt can connect to para_server linked against libssl
100 - Rewrite of the osx writer (output plugin for Mac OS).
101 - audiod: The format specifier for receivers, filters and
102 writers is now treated as a regular expression. This allows
103 to replace 5 lines in the config file (one for each audio
104 format) by one single line. See the manual for details.
105 - The *.cmdline.[ch] files are no longer contained in the released
106 tarballs. This reduces the size of the tarballs but requires
107 gengetopt to build the tarball.
108 - Compiles cleanly also with llvm/clang.
109 - Corrupt mp3 files are handled more gracefully.
110 - The alsa writer uses poll fds instead of computing timeouts.
111 - Cleanup of the generic writer API.
112 - sched: Optimized zero timeouts.
113 - vss timeout cleanups.
114 - oggdec fixes and improvements.
116 --------------------------------------
117 0.4.7 (2011-06-01) "infinite rollback"
118 --------------------------------------
120 The new ao writer, support for ssh RSA keys and a couple of other
123 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
124 platforms through the libao audio library.
125 - Support for RSA keys generated with ssh-keygen.
126 - configure: improved options for ogg/vorbis/speex.
127 - The git version reported by --version always matches HEAD.
128 - The autogen script detects the number of processors and
129 runs a parallel make if possible.
130 - Major cleanup of the crypto API.
131 - Documentation updates.
133 ------------------------------------------
134 0.4.6 (2011-03-31) "deterministic entropy"
135 ------------------------------------------
137 Lots of ogg/vorbis improvements, the new test suite, enhancements
138 for para_gui and a fair amount of other bug fixes.
140 - For DCCP/OGG streams the audio file header is only sent once
141 at the beginning of the stream rather than periodically
142 every five seconds. This reduces network traffic and the
144 - The vorbis comment header is replaced by an empty dummy header
145 before the header is sent over the network. This also results in
146 less network traffic and smaller FEC groups.
147 - The new "test" make target allows to perform some sanity checks prior
148 to installing the package.
149 - ogg timing fixes and performance improvements
150 - Scheduler improvements
151 - Proper exit codes for para_write
152 - para_gui: New option --theme to select a startup theme. Several
153 other improvements and fixes.
154 - aacdec error message cleanups
155 - simplified color error handling
157 --------------------------------------------
158 0.4.5 (2010-12-17) "symmetric randomization"
159 --------------------------------------------
161 Bug fixes, internal cleanups and variable-sized FEC slices.
163 - Contains a fix for an invalid-free-bug in the ogg audio format
165 - Switching off the DCCP sender works again.
166 - para_audiod handles crashes of para_server more robustly.
167 - Internal scheduler and writer cleanups.
168 - Reduced latency due to variable-sized FEC slices.
169 - Improved documentation and error diagnostics.
170 - The build of para_server is now optional, allowing the build
171 to succeed in case libosl is not installed.
173 ------------------------------------------
174 0.4.4 (2010-08-06) "persistent regularity"
175 ------------------------------------------
177 Support for yet another audio format, para_write improvements and
180 - Support for the speex codec.
181 - Support for sample formats other than 16 bit little endian.
182 - error2.h is now created by a perl script which speeds up configure
184 - Fix a bug in the aac decoder which could lead to segfaults in
185 para_filter/para_audiod.
186 - Fixes for autoconf-2.66.
188 ----------------------------------------
189 0.4.3 (2010-07-05) "imaginary radiation"
190 ----------------------------------------
192 Many improvements for the DCCP and the UDP transport, the new user
193 manual and the usual mix of bug fixes and internal improvements.
195 - FEC support for the DCCP sender (Gerrit Renker). The new
196 --dccp_max_slice_size, --dccp_data_slices_per_group and
197 --dccp_slices_per_group options can be used to set the FEC
198 parameters for the DCCP transport.
199 - DNS lookups for UDP targets (Gerrit Renker).
200 - The new user manual replaces the README, README.afs, REQUIREMENTS
201 and INSTALL documents.
202 - Fix an end-of-file detection bug in the oggdec filter.
203 - The new nonblock API.
204 - Both options of the oggdec filter have been removed.
205 - New debug mode for the internal scheduler.
207 ------------------------------------------
208 0.4.2 (2010-04-23) "associative expansion"
209 ------------------------------------------
211 It's been some time since the last release, but finally here is
212 paraslash-0.4.2. The bulk of the changes comes from the new buffer
213 tree API, but there are changes all over the tree. Mainly performance
214 and usability improvements, but also quite some bug fixes.
216 - The new buffer tree API.
217 - DCCP: Support for CCID negotiation (Gerrit Renker).
218 - UDP robustness fixes.
219 - The --bufsize option for mp3dec is gone as it no longer makes sense
220 for the new buffer tree API.
221 - Fix audible buffer underruns for wma streams.
222 - The alsa writer no longer prints meaningless underrun durations.
223 - audiod: Defaults work also for udp streams. If no filter is
224 given for an audio format that is received via upd, fecdec is
225 automatically added as the first filter (along with the decoder).
227 ---------------------------------------
228 0.4.1 (2009-12-22) "concurrent horizon"
229 ---------------------------------------
231 Support for another audio format, minor feature enhancements and lots of bug
232 fixes. All fixes that have been accumulated in the maint branch (in particular
233 those mentionened in the 0.3.6 release notes) appear in this release as well.
236 - new afh option: --human to activate human-readable output.
237 - new server/audiod option: --log-timing to print timing information.
238 - build system improvements.
239 - source code documentation updates.
241 -------------------------------------
242 0.3.6 (2009-12-07) "cubic continuity"
243 -------------------------------------
245 Quite a few bugs have been found and fixed since 0.3.5, so here's
246 another 0.3.x release. No new features.
248 - Always check return value of malloc().
249 - ogg vorbis/FEC: Do not write garbage after the audio file header.
250 - exit if root privileges could not be dropped.
251 - FEC: Fix computation of extra slices.
252 - oss: Fix check for empty input buffer.
253 - Avoid buffer underruns due to filter chain output buffer constraints.
254 - server: Fix assignment of afs_pid.
255 - Don't panic if the afs database contains unknown audio formats.
256 - http/dccp: Do not send the audio file header twice.
257 - FEC: Timing improvements.
259 ----------------------------------------------
260 0.4.0 (2009-11-10) "simultaneous independence"
261 ----------------------------------------------
263 Two significant changes which require the new version number: The
264 improved authentication dialog and the fact that the database code
265 has been moved to a library, libosl. To use the new version, you have
266 to generate new RSA keys, see INSTALL for details. A shell script is
267 provided for conversion of the 0.3 database to the new 0.4 format.
269 - stronger crypto for client authentication
270 - the database code has been moved to a library
271 - improved status item handling
272 - cleanup of the build system
273 - The "-V" option now also prints the git version
274 - the new parser-friendly listing mode for the ls and stat commands
275 - mandatory rc4 encryption
276 - major audio format handler cleanups
277 - (id3,...) tags are no longer stored as a combined string in the database
278 - new mood methods: artist_matches, title_matches, comment_matches,
279 album_matches, year_maches, year.
281 --------------------------------------------
282 0.3.5 (2009-09-21) "symplectic separability"
283 --------------------------------------------
285 Full client support for *BSD Unixes, complete re-write of the ogg
286 vorbis audio format handler, various improvements all over the place
287 and the usual mix of bugfixes. This release marks the end of the 0.3
288 series if no serious problems show up.
290 - the new oss writer (supported on *BSD and Linux)
291 - rewrite of the ogg vorbis audio format handler. It's
292 recommended to replace the chunk tables of existing ogg
293 vorbis files in the afs database by re-adding these files
295 - support for netmask subsets (Gerrit Renker)
296 - the new prebuffer filter
297 - improved signal handling
298 - variable fec output buffer size
299 - improved FEC timing fixes audible buffer underruns in UDP mode
300 - --log_color actually works
301 - new ls option: -d (print dates as seconds after the epoch)
302 - update to gengetopt 2.22.2
303 - support for RSA keys of size > 512 bits
304 - new option "mixer_channel" for para_fade
306 -----------------------------------------
307 0.3.4 (2009-05-07) "elliptic inheritance"
308 -----------------------------------------
310 The new udp sender, forward error correction, colored logs and various
311 other improvements. As the udp sender does not depend on any special
312 libraries, it is built unconditionally.
314 - The udp sender replaces the ortp sender. The new code uses forward
315 error correction to protect against packet losses. Many thanks to
316 Gerrit Renker for providing ipv6 support.
317 - The default port for udp streaming now defaults to 8000, like
318 for the http and the dccp senders/receivers.
319 - Loglevels are now specified as symbolic names, e.g.
321 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
322 - para_server/para_audiod: Color support for log messages.
323 - new options for mp3dec: --ignore-crc, --bufsize
324 - new audiod option: --config-file.
325 - gengetopt cleanups.
326 - Improved help/man pages: The documentation of para_audiod,
327 para_recv, para_filter and para_write now also contains
328 all options of the available receivers/filters/writers. The
329 man page of para_fade contains a description of the different
331 - More source code documentation.
334 --------------------------------------------
335 0.3.3 (2008-12-01) "axiomatic perspectivity"
336 --------------------------------------------
338 Internal code cleanups, bug fixes, improved tag handling and the new
339 amplification filter.
341 - para_server uses the generic scheduling code.
342 - overhaul of the virtual streaming system.
343 - mp3: id3 version 2 support via libid3tag (optional)
344 - ogg: vorbis comment support.
345 - aac meta info support.
346 - mp3 audio format handler cleanups.
347 - new filter: "amp" to amplify the amplitude of the audio stream
348 - new status item/database entry: amplification. It is
349 used by the amp filter to pre-amplify the audio stream.
350 - fix a close-without-open bug in para_write.
351 - fix a bug in com_init() which was introduced in 0.3.2.
352 - better error diagnostics for para_client.
354 -----------------------------------------
355 0.3.2 (2008-04-11) "probabilistic parity"
356 -----------------------------------------
358 The new para_afh executable, scheduling and documentation improvements.
360 - new ls option: -lc (list chunk table)
361 - new executable: para_afh, the stand-alone audio file handler tool
362 - afs commands can send output more than SHMMAX (32MB on Linux). This
363 also reduces the memory usage of commands that produce large amounts
365 - major scheduler and audiod cleanups.
366 - more detailed and much nicer man pages.
368 ---------------------------------------
369 0.3.1 (2008-02-23) "liquid interaction"
370 ---------------------------------------
372 A mix of cleanups, bug fixes, improvements, and some new features. No
373 significant changes to the new database (osl) code, which is generally
376 - Share some similar/duplicate code between the http and the
378 - Generic access control lists for paraslash senders.
379 - dccp sender: Access control lists, connection limiting and support
380 for the allow,deny,on,off,help sender commands.
381 - The default dccp port changed from 5001 to 8000 (suggested by
383 - para_server starts even if not all public keys could be loaded.
384 - Audiod performance improvements.
385 - fix a bug in the "off" command of the http sender.
386 - fix some fd and memory leaks.
387 - Update to gengetopt-2.22.
389 -------------------------------------
390 0.3.0 (2008-01-12) "solar saturation"
391 -------------------------------------
393 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
396 Usually one might expect lots of new features AND a big increase in size
397 for a major release like this.
399 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
400 ever. The decrease in size is mostly due to the removal of some
401 graphical tools (which were only quick hacks anyway). But also the
402 fact that the mysql code is gone cuts down the size a bit.
404 Being independent of mysql comes at a cost: The fact that paraslash
405 now contains its own database (the object storage layer, osl) increases
406 the (stripped) binary size of para_server by ~50K on i386.
408 - no more restrictions on unique basenames.
409 - independent of mysql: The new self-contained object
410 storage layer (osl) replaces the mysql database.
411 - New executable para_fsck: Check integrity of osl tables.
413 - Reliable audio file move/rename detection.
414 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
415 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
417 - the new osl-based audio file selector (afs) replaces the random,
418 the playlist and the mysql selector of paraslash-0.2.x.
419 - IPv6 support (thanks to Gerrit Renker).
420 - paraslash-0.2.x streams are now called "moods". Writing
421 0.3.x-mood definitions should be both easier and more
422 powerful than writing 0.2.x-stream definitions.
423 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
424 been removed. The world is a better place without them. However,
425 para_gui is still there.
426 - afs tracks audio file selection also in playlist mode.
427 - few easy-to-use afs commands replace the many not-so-easy-to-use
428 mysql commands (and are available also in playlist mode).
429 - Improved error subsystem.
430 - The earth-shaking new logo.
432 -----------------------------------------
433 0.2.17 (2007-11-20) "isotropic threshold"
434 -----------------------------------------
436 Mainly bugfixes and cleanups in this version which marks the end of
437 the 0.2.x series if no serious bugs show up after the release.
439 - mysql_selector: fix a locking bug.
440 - universal chunk queueing.
441 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
443 - be more carful wrt. signed vs. unsigned argument passing.
444 - cleanup error.h and fix some references to invalid error
446 - update to gengetopt-2.21.
447 - update to ortp-0.13.1.
448 - autoconf: extend checks for headers, library functions and
449 compiler characteristics.
450 - Fix streaming of large mp3 files.
451 - Fix an off-by-one bug in playlist handling.
453 --------------------------------------
454 0.2.16 (2007-04-05) "neural discharge"
455 --------------------------------------
457 The main change in this release is the major audio format handler
458 cleanup which removes some similar/duplicate code and makes it easier
459 to implement plugins for other audio formats. Of course, the usual mix
460 of other improvements/changes/bugfixes also made it into the release.
462 - simplified audio format handlers (most of the handling functions
463 were moved one layer up to the virtual streaming system).
464 - para_server uses mmap to read audio files
465 - repositioning of mp3 streams is much faster, in particular for
466 jumping near the end of large mp3 files.
467 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
469 - fix a bug in para_filter that caused decoding of aac files
470 to start only after a few seconds.
471 - fix osx_writer hangs
472 - simplified dccp code (thanks to Gerrit Renker)
473 - the compress filter works also on big endian systems (ppc)
475 -----------------------------------------
476 0.2.15 (2007-02-16) "inductive resonance"
477 -----------------------------------------
479 Minor improvements, more documentation and a bunch of bug fixes.
481 - para_server: The server.users file is only read once on server
482 startup rather than for each connection
483 - mp3dec: Fix decoding of corrupt mp3 files
484 - afs (audio file sender) is now called vss (virtual streaming
485 system). Consequently, the permission flags specified in
486 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
487 become VSS_READ and VSS_WRITE respectively.
488 - para_audiod/para_filter: Fix a bug that caused the last chunk
489 of audio data not being written under certain circumstances
490 - audiod: compute the difference of server time and local time
492 - para_server/para_audiod: Fix some memory leaks
493 - documentation improvements
494 - configure.ac: fix checks for para_krell
497 -------------------------------------------
498 0.2.14 (2006-10-15) "transient singularity"
499 -------------------------------------------
501 The only major enhancement of this version is the osx writer which completes
502 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
503 until now for reasons beyond the scope of this changelog entry.
505 - new output plugin for Mac Os: the osx writer
506 - rename configure command line options from --enable-xxx-headers to
507 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
508 - configure: new command line options: --with-mad-headers,
509 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
510 - some robustness fixes
511 - dymamic audio format recognition for audiod
512 - para_server: new command line option: --autoplay_delay
513 - para_audiod: new command line option: --clock_diff_count
515 ---------------------------------------
516 0.2.13 (2006-07-14) "sonic convolution"
517 ---------------------------------------
519 A bunch of new features and core changes.
521 - the new paraslash scheduler, short and sweet.
522 - Support for m4a/mp4 files via the new aac audio format
523 handler/filter (requires libfaad).
524 - each writer has its own command line parser, just like
525 para_recv and para_filter.
526 - para_client and para_audioc use the error subsystem
527 - writers are integrated in para_audiod (currently linux-only)
528 - para_client is integrated in para_audiod
529 - random/playlist selector: improved info strings
530 - new audiod commands: tasks, kill
531 - update to libortp-0.10.1
532 - para_fade: wake time defaults to 8 hours from now
533 - update to autoconf-2.60
535 ------------------------------------------
536 0.2.12 (2006-05-12) "oriented abstraction"
537 ------------------------------------------
539 Many user-visible changes in this release and lots of new
543 - the new optional dccp sender/receiver. It uses the datagram
544 congestion control protocol. You'll need a fairly new kernel
546 - paraslash works on Mac OS X (thanks to Gerd Becker)
547 - para_play renamed to para_write
548 - modular output plugin design (writers) for para_write
549 - new file_writer output plugin for para_write
550 - compress filter speed improvements
551 - update to libortp-0.9.1
552 - update to gengetopt-2.17rc
553 - para_client no longer depends on libreadline (as the
554 code for the interactive mode was removed).
555 - gcc-2-95 is no longer a supported compiler. It may still
556 work, but it gets no more testing.
557 - the tarball no longer contains the screenshot images which
558 reduces its size quite a bit.
559 - configure: new command line options: --enable-mysql-headers
560 and --enable-mysql-libs
562 ------------------------------------
563 0.2.11 (2006-03-11) "atomic duality"
564 ------------------------------------
566 Here it is, the first paraslash release developed with git. There
567 are fairly many user-visible changes in this release. As two out of
568 the three "database tools" of paraslash don't use a database at all,
569 they are now called "audio file selectors" instead.
572 - the cdt command (change database tool) becomes chs (change
574 - no more colon separators: The syntax of some options of
575 para_audiod and para_filter have changed. Use --help for
576 more info (and some examples).
577 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
578 - switch from cvs to git (should've done that earlier)
579 - the new ipc subsystem
580 - new audio file selector: playlist
581 - para_server: the dopey selector is now called "random",
582 and is the default selector. Use the --selector option to
583 choose another selector at startup, or the chs command to
584 change the selector at runtime.
585 - X86_64 fixes (thanks to Steffen Klassert)
588 --------------------------------------
589 0.2.10 (2006-02-17) "cyclic attractor"
590 --------------------------------------
592 Huge documentation update, a scrollable window for para_gui, ortp
593 improvements, and of course many small fixes not mentioned here.
594 The diffstat below is rather misleading as most insertions are due
595 to the new source documentation.
598 - para_server also uses the new error subsystem
599 - lots of new documentation (UTSL)
601 - keysyms for cursor keys and for next/previous page keys
602 - scrollable output window
603 - new internal commands: scroll up/down, page up/down
604 - fix color of command output.
605 - ortp: the --chunk_time and --header flags are no longer needed
606 for para_recv/para_audiod as this information is now encoded in
607 each rtp packet sent by para_server.
609 -------------------------------------------
610 0.2.9 (2006-01-24) "progressive turbulence"
611 -------------------------------------------
613 Internal audiod receivers/filters, the new error subsystem and
614 a lot of small improvements.
616 - para_recv and para_filter are integrated into the para_audiod
617 binary, i.e. audiod no longer spawns a new process for
618 each receiver/filter. As para_recv and para_filter might be
619 useful as standalone programs, they still get built (linked
620 against the same object files that are also used for audiod).
621 - further ortp timing improvements should reduce the CPU usage
622 of the ortp receiver.
623 - improved audio grabbing. The 'grab' command of para_audiod
624 has its own set of command line options. Read the output of
625 "para_audioc help grab" for more info.
626 - oggdec: configurable input prebuffer size.
627 - the new error subsystem gives better error diagnostics
628 and reduces code size.
630 -----------------------------------------
631 0.2.8 (2006-01-02) "dynamic accumulation"
632 -----------------------------------------
634 The new modular filter design and the para_play-hangs bugfix.
636 - new executable: para_filter. It combines para_mp3dec,
637 para_oggdec and para_compress. It also adds a further filter
638 type, wav, that just inserts a wave header at the desired point
639 of the filter chain. All 'piping' is done in-memory (i.e. no
640 read/write operations are used).
641 - para_play: fix a stupid bug that caused it to hang under
642 certain circumstances.
644 -------------------------------------------
645 0.2.7 (2006-12-27) "transparent invariance"
646 -------------------------------------------
648 Not many user-visible changes but a fair amount of internal improvements.
651 - The http sender buffers data if it can not be sent
652 out immediately (because the socket is not writable). This
653 should prevent para_server from shutting down the connection
654 too early on a loaded network.
655 - para_play also prebuffers data if it is told to start at a
656 future time by the --start_time option.
657 - The return of para_recv: It combines para_ortp_recv and
658 para_http_recv. Use the --receiver option to switch between
659 the two. para_recv builds without libortp, but contains
660 only the http receiver in this case.
661 - update to ortp 0.8.1. As this ortp release contains incompatible
662 changes, para_recv-0.2.7 won't link against older ortp libs.
663 - improved ortp timings.
664 - use of gcc-extensions that #define away for non-gcc and
667 -------------------------------------------
668 0.2.6 (2005-10-29) "recursive compensation"
669 -------------------------------------------
671 Transparent session encryption (uses openssl's Alleged RC4 cipher),
672 the internal find command and several other improvements and cleanups.
674 - Encrypt the session if encryption is requested by the client
675 (default for para_client 0.2.6). This is backwards
676 compatible, so older clients can still connect to para_server
677 0.2.6. Use the new client option --plain to request an
678 uncrypted session (off by default, must be set to on in
679 order to connect to para_server 0.2.x with 0 <= x <= 5).
680 - para_server uses an internal function to locate audio files
681 rather than calling find(1). The server option
682 --mysql_audio_file_dir replaces --mysql_find_cmd.
683 - documentation update
685 - header file cleanup
686 - para_client code cleanup
687 - para_gui: faster display of output of display commands
689 ------------------------------------------
690 0.2.5 (2005-10-13) "aggressive resolution"
691 ------------------------------------------
693 This release adds internal senders, i.e. no more external programs are
694 spawned for sending out the audio data. There are two different senders
695 available: The http sender and the ortp sender (former para_send which
696 is no longer needed).
698 The new sender code has a plugin-like design so it can be easily
699 extended should there be be any future need for supporting another
700 network streaming protocol. All senders are completely independent of
701 each other. In particular, the http and the ortp sender can operate
704 - new server command: sender to control senders at runtime.
705 Read the output of "para_server -h" and "para_client help
706 sender" for more information.
707 - para_recv renamed to para_ortp_recv
708 - new executable: para_http_recv, a simple command line
710 - major afs/mp3/ogg code simplifications due to internal
712 - ogg timing improvements
713 - fix several minor memory leaks (found by valgrind)
714 - empty stream definitions work again
715 - com_ne(): ignore errors on remove
716 - audiod: fix segfault on server restart
718 ---------------------------------------
719 0.2.4 (2005-09-21) "toxic anticipation"
720 ---------------------------------------
722 Several small improvements, fixes and the new grab command.
725 - new command: "grab" to grab the output of the stream reader
726 or any filters. Read the output of "para_audioc help grab"
727 for more information.
730 - audioc: new command line option: --bufsize to specify a
731 buffer size different from the default size 8192.
732 - improved error diagnostics for para_play.
733 - new configure option: --enable-ssldir so search for openssl in
735 - sdl_gui: Make it look nice again for 1024x768
736 - server: report total size of memory allocated with sbrk by malloc,
737 new command line option: --announce_time
739 -----------------------------------------
740 0.2.3 (2005-09-01) "hydrophilic movement"
741 -----------------------------------------
743 Two new executables and major feature enhancements.
745 - audiod filters: It is now possible to specify arbitrary many
746 (including none) filters for each supported audio
747 format. This can be used e.g. for normalizing volume,
748 transforming or grabbing the audio stream, or for using
749 visualizers. Read the output of "para_audiod -h" for the
750 syntax of the new --filter_cmd option.
751 - new executable: para_play, a tiny alsa player. It
752 can play wave files or raw pcm (16 bit little endian)
754 - new executable: para_compress, a dynamic range compressor
755 intended to keep audio output at a consistent volume. Derived
756 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
757 - audiod: New option: --stream_delay. This can be used in
758 a local network to syncronize the audio output of all
759 clients that play the same stream.
761 ------------------------------------------
762 0.2.2 (2005-08-19) "tangential excitation"
763 ------------------------------------------
765 Mostly internal changes in this release, but also some new commands
766 for the mysql database tool.
768 - cleanup exec.c, fix para_exec bug
769 - compile time loglevel (log messages below the given level
770 won't be compiled in, which reduces the size of the
772 - new log macros that shorten the size of the source code.
773 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
774 to send only zeros. With this workaround, para_audioc works
776 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
777 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
778 (new entry), "snp" (set numplayed). Read the manual for more
781 ---------------------------------------
782 0.2.1 (2005-08-15) "surreal experience"
783 ---------------------------------------
785 Here comes paraslash-0.2.1. It contains a couple of new features and,
786 surprise, only minor bug fixes.
788 - kill noisy mp3 debug message
789 - cleanup of the build system
790 - para_server and para_client directly use the crypto routines
791 of the openssl library rather than invoking the openssl command
793 - server/audiod: new option --user to switch to the given user
794 when invoked as root. Read the output of "para_server -h" for
796 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
797 status. Default: "para_audioc stat"
798 - sdl_gui: new option --pic_cmd to be used to download the picture.
799 Default: "para_client pic"
800 - audiod: 5 slots ought to be enough for everybody
801 - audiod: new status item: Uptime, kill hup command
803 ------------------------------------------
804 0.2.0 (2005-08-06) "distributed diffusion"
805 ------------------------------------------
807 After several month of increased development activity, paraslash-0.2.0
808 has arrived. It contains many new features and is much more
809 self-contained than the old 0.1.x series. Enjoy!
812 - para_server: fix hang on song change and crash on sighup.
813 Speed up mysql queries. The DIR_LIKE macro is gone.
814 - new executables: para_audiod, the local audio daemon that
815 starts playback (uses SCM_CREDENTIALS socket magic) and
816 para_audioc, the corresponding client.
817 - new executables: para_mp3dec/para_oggdec, two really teensy
818 decoders. para_mp3dec is based on libmad, para_oggdec requires
820 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
821 they are now called para_send and para_recv respectively.
822 - documentation updates
823 - para_gui is themable. For now there is the default theme that
824 looks as before and the simple theme: blue and easy.
825 - gui: audio streaming is now handled by audiod. Time display shows
826 playback time rather than streaming time
827 - slider: update to libzmw-0.2.0
828 - para_krell: fix crash on server shutdown
829 - switch from gzip to bzip2
831 ----------------------------------------
832 0.1.7 (2005-04-18) "melting penetration"
833 ----------------------------------------
835 The main change in this release is clearly the oggvorbis rewrite,
836 but there are also lots of smaller changes. If you intend to use both
837 the mp3 and the ogg plugin, it is recommended to use software mixing,
838 e.g. the dmix plugin which is provided by ALSA.
840 - new executables: para_ovsend and para_ovrecv for sending/receiving
841 oggvorbis files via rtp. Requires the open rtp library. Get it at
842 http://www.linphone.org/ortp/
843 - rewrite of the ogg_vorbis core code
844 - configure detects libzmw and, if detected, includes
845 para_slider to the list of binaries to be built by make
846 - server stream writers read from their associated fifo rather
848 - slider: two new sliders, lastplayed and numplayed
849 - fix nasty double free bug which caused random segfaults in case of
850 mp3 files with invalid header information
851 - gui: new command line option: --stream_timeout=seconds to
852 deactivate a slot if it is idle for that many seconds (default=`5')
855 ---------------------------------------
856 0.1.6 (2005-03-05) "asymptotic balance"
857 ---------------------------------------
859 Only little user-visible changes in this release. Mainly bugfixes and
860 core code cleanup. This is probably the most stable version ever if you
863 - fix several memory leaks
864 - rename default name of mysql database from "music" to "paraslash".
865 Use para_server's --mysql_database option if you do not want to
866 rename your old database.
867 - rework ogg vorbis code
868 - make update command work on mysql servers with LOCAL_INFILE
870 - gui: improved stream I/O (slots)
871 - simplified audio format API
872 - para_pob_ogg is gone
874 ------------------------------------
875 0.1.5 (2004-12-31) "opaque eternity"
876 ------------------------------------
878 Let's slide gently into the new year.
880 - new: para_slider (not built automatically, type "make
881 para_slider" to build). A toy for those who always felt that
882 creating stream definitions is difficult. See screenshots,
883 README and FEATURES for more info.
884 - improved signal handling. Fixes server segfault on SIGHUP
885 for linux kernels newer than Aug 24 2004 and makes para_gui
887 - reload database tool on SIGHUP
888 - improved help message for sl
889 - do not log "broken pipe" messages as errors. They are
891 - fix wrong error message on permission errors
893 -----------------------------------------
894 0.1.4 (2004-12-19) "tunneling transition"
895 -----------------------------------------
897 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
898 Hopefully, most of them got wiped out with this release. Some
899 enhancements went also in.
901 - improved error diagnostics for all commands
902 - stradd/picadd: overwrite previous contents if entry already
903 exists, rather than returning errors
904 - stradd: use current stream if invoked without args
905 - faster (and hopefully more stable) ogg-vorbis handling
906 - para_krell: reap children to avoid zombie-flooding in case
908 - si: report also server pid
909 - server: don't busy-loop if dbtool reports only invalid files.
910 - gui: CTRL+C works again, fix stream_read command line option
912 - fix mysql dbtool startup in case no database exists
913 - many small fixes and cleanups
915 ---------------------------------------
916 0.1.3: (2004-12-10) "vanishing inertia"
917 ---------------------------------------
919 Starting from this release, the database tools are integrated in the
920 server binary. This decreases server startup time, reduces code size
921 and speeds up database commands. However, the layout of the underlying
922 mysql database changed only slightly and 0.1.3 should be backwards
923 compatible in that respect.
927 - If mysql is not detected at compile time, or fails to init
928 at runtime, fall back to the dopey database tool which should
930 - para_dbtool and dbtool.conf are gone. All mysql specific
931 options are read from server.conf and are prefixed by 'mysql_'.
932 - new command: cdt (change database tool)
933 - new command line option: dbtool (choose startup database tool)
934 - The name of current stream is now stored in the database,
935 so paraslash remembers its current stream when restarted.
936 - new command: csp (change stream and play)
937 - para_gui also reports current database tool and server uptime
939 -------------------------------------------
940 0.1.2: (2004-11-28) "spherical fluctuation"
941 -------------------------------------------
943 Point release before the big dbtool changes go in.
945 - dbtool: rename ca to cam (copy all meta data). It now also
946 copies numplayed and lastplayed time as well as the picture
948 - fix endless-loop-bug caused by mp3 files with invalid header
950 -----------------------------------------
951 0.1.1: (2004-11-05) "floating atmosphere"
952 -----------------------------------------
955 - new dbtool command: mbox. Browse your sound-file collection
956 with your favorite mail reader.
957 - several small fixes
959 -------------------------------------
960 0.1.0: (2004-10-22) "rotating cortex"
961 -------------------------------------
963 - fix logging bug for loglevel > VERBOSE
965 - correct timings for vbr mp3s
966 - modular audio format support
967 - ogg-vorbis support (experimental)
968 - new server option: autoplay
970 -----------------------------------------
971 0.0.99: (2004-07-25) "harmonic deviation"
972 -----------------------------------------
974 - rename projectname from icc to paraslash (play, archive, rate
975 and stream large audio sets happily)
976 - paraslash is no longer restricted to one particular audio
978 - new dbtool commands (stradd, strq, strdel) for easy stream
979 managment w/o configuration file. That obsoletes stream_defs
980 file/config option for dbtool.
981 - picadd accepts jpeg data from stdin
982 - new server commands: ps (select previous stream), sc (song change)
983 - new default pictures for sdl_gui
984 - gui: new key_map option for binding commands and internal
985 functions to arbitrary keys, nice help screen, rip out
986 soundcard/linux specific stuff, avoid noise artefacts while jumping,
987 show silly logo on startup
988 - new executables: para_fade for fading volume, para_dbadm for
989 manipulating attributes
990 - cdb adds _all_ tables to mysql database
991 - revised and beautified documentation
992 - sample dbtool rewritten in C
995 ---------------------------------------------
996 0.0.98: (2003-12-26) "incremental smoothness"
997 ---------------------------------------------
999 - kick icecast in favour of poc. That removes some races and reduces
1000 core code considerably.
1001 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1002 give finer info on afs' status.
1003 - gui can start decoder (see config options). Further new gui
1004 commands: refresh (^L), jmp (F1-F10)
1005 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1006 terminates gui. This fixes dead instances consuming memory
1008 - new dbtool command: verb for sending verbatim sql queries.
1009 - fix pid_list races (by removing pid_list)
1012 --------------------
1013 0.0.97: (2003-10-26)
1014 --------------------
1016 - installation prefix now defaults to /usr/local
1017 - new commands for gui: snozze, sleep and reread config
1018 - config file for gui and sdl_gui
1019 - fix problems with filenames containing funny characters
1020 (reported by Thomas Forell)
1021 - improved signal handling for gui, now it rereads conf on SIGHUP
1022 - new dbtool command: cdb (create database)
1023 - switch from argtable to gengetopt
1024 - major code cleanup and speed improvements
1025 - fix several potential buffer overflows
1026 - many small fixes and cleanups
1032 - easy stream_defs syntax
1033 - sdl_gui can display images associated to the file being played
1034 - Major feature enhancements for icc_gui including dynamic text
1035 placement and the top/bottom window design
1036 - vrfy/clean now also checks for NULL values in attributes as
1037 well as for invalid picture pointers
1038 - fix long outstanding case sensitivity bug
1039 - many small fixes and cleanups
1045 - sdl gui runs much faster
1046 - new dbtool command: ca (copy attributes)
1047 - count and display number of times the song has been played
1048 - new feature: scoring
1049 - command line options for sdl_gui
1050 - simpler syntax of streams file
1051 - decrease network traffic of stat
1053 - many small fixes and cleanups
1059 - new server command: ns (next stream)
1060 - new icc_gui command: c (change stream)
1062 - stat shows also id3 tag info
1064 - log flodding bug fixed
1065 - many small fixes and cleanups
1071 - colors for icc_gui
1072 - icc_gui sets volume directly (linux only)
1073 - proper locking that fixes some races
1074 - fix security bug that caused commands to be executed even
1075 with unsufficient permissions
1076 - new command: hup to make all servers reread their configuration file
1077 - icecast meta data streaming
1078 - many small fixes and cleanups
