1 ------------------------------------------
2 0.?.? (to be announced) "spectral gravity"
3 ------------------------------------------
5 - UTF8 support for para_gui and the mp3 audio format handler.
6 - Scheduler improvements and fixes.
7 - The obsolete gettimeofday() function has been replaced
8 by clock_gettime() on systems which support it.
10 -----------------------------------------
11 0.4.12 (2012-12-20) "volatile relativity"
12 -----------------------------------------
13 The new command line player, the resample filter, ALSA support for
14 para_fade, and the improved build system are the highlights of this
15 release which probably marks the end of the 0.4.x series.
17 - The afh receiver and the para_play executable.
18 - The resample filter: A sample rate converter based on
20 - The "versions" directory has been removed from the master
21 branch. The tarballs of the old releases are now available
22 in the new "releases" branch.
23 - Overhaul of the build system: All generated files are now
24 written to the "build" directory.
25 - The modular mixer API and the alsa mixer.
26 - Minor fixes for the osx writer.
28 --------------------------------------
29 0.4.11 (2012-07-20) "mutual diversity"
30 --------------------------------------
32 The major feature in this release is the new sideband API for
33 client-server communication. This API will be used exclusively starting
34 with 0.5.0, which breaks backward compatibility but allows to get rid
35 of quite some compatibility code. Other noteworthy changes include
36 decoder latency improvements and a long-standing bug fix for the
39 - Sideband connections: If both para_server and para_client
40 support this feature, data is sent as a multiplexed stream.
41 - The --no_default_filters option of para_filter has been
43 - Several fixes and latency improvements to various decoders.
44 - The ALSA writer now limits the prebuffer time to 500ms.
45 - Documentation improvements.
46 - Overhaul of the command_util.sh script.
47 - Fixes for some minor problems found by the clang analyzer.
48 - Compiles (almost) without warnings on gcc-3.
49 - Robustness improvements of the buffer tree code.
51 ------------------------------------------
52 0.4.10 (2012-03-30) "heterogeneous vacuum"
53 ------------------------------------------
55 Nothing earth-shaking in this release, but quite a few usability
56 improvements and the usual mix of cleanups and fixes.
58 - The --no_default_filters option of para_filter has been
59 deprecated. It still works but has no effect and will be
60 removed in the next version.
61 - para_gui now prints also the stderr output of the executing
62 command in the bottom window.
63 - Cleanup and consolidation of the various wrappers for
64 write(), writev(), send() and friends.
65 - The obscure error messages on mmap() failures have been
66 replaced by meaningful messages. This affects mainly
68 - para_audioc: Cleanups and memory leak fixes.
69 - Test 0004-server no longer fails if para_server is not
71 - New configure options: --with-id3tag-{headers,libs}.
73 -------------------------------------
74 0.4.9 (2011-12-06) "hybrid causality"
75 -------------------------------------
77 Support for another audio format, interactive mode for para_client
78 and para_audiod and many small improvements/fixes all over the place.
80 - Support for flac, the free lossless audio codec.
81 - Fix for an endless loop in the mp3 decoder for certain
83 - When executed without specifying a command, para_client
84 and para_audioc start an interactive shell (requires
85 libreadline being installed). The interactive mode offers
86 full tab completion and command line history.
87 - autogen.sh now detects a distcc setup and adjusts the
88 parameter for the -j option of make accordingly.
89 - Shared memory areas are no longer restricted to 64K. We now
90 detect the maximal size of a shared memory area at runtime.
91 - cleanup of the internal uptime API.
92 - para_server prefaults the mmapped audio file to avoid
94 - A new test for the test-suite that exercises the
95 communication between para_server and para_audiod.
96 - The alsa writer eats up less CPU cycles when configured to
98 - Simplified and unified receiver code.
100 - Commands which print a list of matching audio files now
101 emit a meaningful error message if no audio file matched the
104 --------------------------------------
105 0.4.8 (2011-08-19) "nested assignment"
106 --------------------------------------
108 Gcrypt support, the overhauled osx writer and regex format specifiers
109 are the highlights of this release.
111 - support for libgcrypt as a drop-in replacement for openssl.
112 Run configure --enable-cryptolib=gcrypt to link against
113 libgcrypt. The two crypto implementations are compatible to
114 each other, i.e. a para_client executable linked against
115 gcrypt can connect to para_server linked against libssl
117 - Rewrite of the osx writer (output plugin for Mac OS).
118 - audiod: The format specifier for receivers, filters and
119 writers is now treated as a regular expression. This allows
120 to replace 5 lines in the config file (one for each audio
121 format) by one single line. See the manual for details.
122 - The *.cmdline.[ch] files are no longer contained in the released
123 tarballs. This reduces the size of the tarballs but requires
124 gengetopt to build the tarball.
125 - Compiles cleanly also with llvm/clang.
126 - Corrupt mp3 files are handled more gracefully.
127 - The alsa writer uses poll fds instead of computing timeouts.
128 - Cleanup of the generic writer API.
129 - sched: Optimized zero timeouts.
130 - vss timeout cleanups.
131 - oggdec fixes and improvements.
133 --------------------------------------
134 0.4.7 (2011-06-01) "infinite rollback"
135 --------------------------------------
137 The new ao writer, support for ssh RSA keys and a couple of other
140 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
141 platforms through the libao audio library.
142 - Support for RSA keys generated with ssh-keygen.
143 - configure: improved options for ogg/vorbis/speex.
144 - The git version reported by --version always matches HEAD.
145 - The autogen script detects the number of processors and
146 runs a parallel make if possible.
147 - Major cleanup of the crypto API.
148 - Documentation updates.
150 ------------------------------------------
151 0.4.6 (2011-03-31) "deterministic entropy"
152 ------------------------------------------
154 Lots of ogg/vorbis improvements, the new test suite, enhancements
155 for para_gui and a fair amount of other bug fixes.
157 - For DCCP/OGG streams the audio file header is only sent once
158 at the beginning of the stream rather than periodically
159 every five seconds. This reduces network traffic and the
161 - The vorbis comment header is replaced by an empty dummy header
162 before the header is sent over the network. This also results in
163 less network traffic and smaller FEC groups.
164 - The new "test" make target allows to perform some sanity checks prior
165 to installing the package.
166 - ogg timing fixes and performance improvements
167 - Scheduler improvements
168 - Proper exit codes for para_write
169 - para_gui: New option --theme to select a startup theme. Several
170 other improvements and fixes.
171 - aacdec error message cleanups
172 - simplified color error handling
174 --------------------------------------------
175 0.4.5 (2010-12-17) "symmetric randomization"
176 --------------------------------------------
178 Bug fixes, internal cleanups and variable-sized FEC slices.
180 - Contains a fix for an invalid-free-bug in the ogg audio format
182 - Switching off the DCCP sender works again.
183 - para_audiod handles crashes of para_server more robustly.
184 - Internal scheduler and writer cleanups.
185 - Reduced latency due to variable-sized FEC slices.
186 - Improved documentation and error diagnostics.
187 - The build of para_server is now optional, allowing the build
188 to succeed in case libosl is not installed.
190 ------------------------------------------
191 0.4.4 (2010-08-06) "persistent regularity"
192 ------------------------------------------
194 Support for yet another audio format, para_write improvements and
197 - Support for the speex codec.
198 - Support for sample formats other than 16 bit little endian.
199 - error2.h is now created by a perl script which speeds up configure
201 - Fix a bug in the aac decoder which could lead to segfaults in
202 para_filter/para_audiod.
203 - Fixes for autoconf-2.66.
205 ----------------------------------------
206 0.4.3 (2010-07-05) "imaginary radiation"
207 ----------------------------------------
209 Many improvements for the DCCP and the UDP transport, the new user
210 manual and the usual mix of bug fixes and internal improvements.
212 - FEC support for the DCCP sender (Gerrit Renker). The new
213 --dccp_max_slice_size, --dccp_data_slices_per_group and
214 --dccp_slices_per_group options can be used to set the FEC
215 parameters for the DCCP transport.
216 - DNS lookups for UDP targets (Gerrit Renker).
217 - The new user manual replaces the README, README.afs, REQUIREMENTS
218 and INSTALL documents.
219 - Fix an end-of-file detection bug in the oggdec filter.
220 - The new nonblock API.
221 - Both options of the oggdec filter have been removed.
222 - New debug mode for the internal scheduler.
224 ------------------------------------------
225 0.4.2 (2010-04-23) "associative expansion"
226 ------------------------------------------
228 It's been some time since the last release, but finally here is
229 paraslash-0.4.2. The bulk of the changes comes from the new buffer
230 tree API, but there are changes all over the tree. Mainly performance
231 and usability improvements, but also quite some bug fixes.
233 - The new buffer tree API.
234 - DCCP: Support for CCID negotiation (Gerrit Renker).
235 - UDP robustness fixes.
236 - The --bufsize option for mp3dec is gone as it no longer makes sense
237 for the new buffer tree API.
238 - Fix audible buffer underruns for wma streams.
239 - The alsa writer no longer prints meaningless underrun durations.
240 - audiod: Defaults work also for udp streams. If no filter is
241 given for an audio format that is received via upd, fecdec is
242 automatically added as the first filter (along with the decoder).
244 ---------------------------------------
245 0.4.1 (2009-12-22) "concurrent horizon"
246 ---------------------------------------
248 Support for another audio format, minor feature enhancements and lots of bug
249 fixes. All fixes that have been accumulated in the maint branch (in particular
250 those mentionened in the 0.3.6 release notes) appear in this release as well.
253 - new afh option: --human to activate human-readable output.
254 - new server/audiod option: --log-timing to print timing information.
255 - build system improvements.
256 - source code documentation updates.
258 -------------------------------------
259 0.3.6 (2009-12-07) "cubic continuity"
260 -------------------------------------
262 Quite a few bugs have been found and fixed since 0.3.5, so here's
263 another 0.3.x release. No new features.
265 - Always check return value of malloc().
266 - ogg vorbis/FEC: Do not write garbage after the audio file header.
267 - exit if root privileges could not be dropped.
268 - FEC: Fix computation of extra slices.
269 - oss: Fix check for empty input buffer.
270 - Avoid buffer underruns due to filter chain output buffer constraints.
271 - server: Fix assignment of afs_pid.
272 - Don't panic if the afs database contains unknown audio formats.
273 - http/dccp: Do not send the audio file header twice.
274 - FEC: Timing improvements.
276 ----------------------------------------------
277 0.4.0 (2009-11-10) "simultaneous independence"
278 ----------------------------------------------
280 Two significant changes which require the new version number: The
281 improved authentication dialog and the fact that the database code
282 has been moved to a library, libosl. To use the new version, you have
283 to generate new RSA keys, see INSTALL for details. A shell script is
284 provided for conversion of the 0.3 database to the new 0.4 format.
286 - stronger crypto for client authentication
287 - the database code has been moved to a library
288 - improved status item handling
289 - cleanup of the build system
290 - The "-V" option now also prints the git version
291 - the new parser-friendly listing mode for the ls and stat commands
292 - mandatory rc4 encryption
293 - major audio format handler cleanups
294 - (id3,...) tags are no longer stored as a combined string in the database
295 - new mood methods: artist_matches, title_matches, comment_matches,
296 album_matches, year_maches, year.
298 --------------------------------------------
299 0.3.5 (2009-09-21) "symplectic separability"
300 --------------------------------------------
302 Full client support for *BSD Unixes, complete re-write of the ogg
303 vorbis audio format handler, various improvements all over the place
304 and the usual mix of bugfixes. This release marks the end of the 0.3
305 series if no serious problems show up.
307 - the new oss writer (supported on *BSD and Linux)
308 - rewrite of the ogg vorbis audio format handler. It's
309 recommended to replace the chunk tables of existing ogg
310 vorbis files in the afs database by re-adding these files
312 - support for netmask subsets (Gerrit Renker)
313 - the new prebuffer filter
314 - improved signal handling
315 - variable fec output buffer size
316 - improved FEC timing fixes audible buffer underruns in UDP mode
317 - --log_color actually works
318 - new ls option: -d (print dates as seconds after the epoch)
319 - update to gengetopt 2.22.2
320 - support for RSA keys of size > 512 bits
321 - new option "mixer_channel" for para_fade
323 -----------------------------------------
324 0.3.4 (2009-05-07) "elliptic inheritance"
325 -----------------------------------------
327 The new udp sender, forward error correction, colored logs and various
328 other improvements. As the udp sender does not depend on any special
329 libraries, it is built unconditionally.
331 - The udp sender replaces the ortp sender. The new code uses forward
332 error correction to protect against packet losses. Many thanks to
333 Gerrit Renker for providing ipv6 support.
334 - The default port for udp streaming now defaults to 8000, like
335 for the http and the dccp senders/receivers.
336 - Loglevels are now specified as symbolic names, e.g.
338 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
339 - para_server/para_audiod: Color support for log messages.
340 - new options for mp3dec: --ignore-crc, --bufsize
341 - new audiod option: --config-file.
342 - gengetopt cleanups.
343 - Improved help/man pages: The documentation of para_audiod,
344 para_recv, para_filter and para_write now also contains
345 all options of the available receivers/filters/writers. The
346 man page of para_fade contains a description of the different
348 - More source code documentation.
351 --------------------------------------------
352 0.3.3 (2008-12-01) "axiomatic perspectivity"
353 --------------------------------------------
355 Internal code cleanups, bug fixes, improved tag handling and the new
356 amplification filter.
358 - para_server uses the generic scheduling code.
359 - overhaul of the virtual streaming system.
360 - mp3: id3 version 2 support via libid3tag (optional)
361 - ogg: vorbis comment support.
362 - aac meta info support.
363 - mp3 audio format handler cleanups.
364 - new filter: "amp" to amplify the amplitude of the audio stream
365 - new status item/database entry: amplification. It is
366 used by the amp filter to pre-amplify the audio stream.
367 - fix a close-without-open bug in para_write.
368 - fix a bug in com_init() which was introduced in 0.3.2.
369 - better error diagnostics for para_client.
371 -----------------------------------------
372 0.3.2 (2008-04-11) "probabilistic parity"
373 -----------------------------------------
375 The new para_afh executable, scheduling and documentation improvements.
377 - new ls option: -lc (list chunk table)
378 - new executable: para_afh, the stand-alone audio file handler tool
379 - afs commands can send output more than SHMMAX (32MB on Linux). This
380 also reduces the memory usage of commands that produce large amounts
382 - major scheduler and audiod cleanups.
383 - more detailed and much nicer man pages.
385 ---------------------------------------
386 0.3.1 (2008-02-23) "liquid interaction"
387 ---------------------------------------
389 A mix of cleanups, bug fixes, improvements, and some new features. No
390 significant changes to the new database (osl) code, which is generally
393 - Share some similar/duplicate code between the http and the
395 - Generic access control lists for paraslash senders.
396 - dccp sender: Access control lists, connection limiting and support
397 for the allow,deny,on,off,help sender commands.
398 - The default dccp port changed from 5001 to 8000 (suggested by
400 - para_server starts even if not all public keys could be loaded.
401 - Audiod performance improvements.
402 - fix a bug in the "off" command of the http sender.
403 - fix some fd and memory leaks.
404 - Update to gengetopt-2.22.
406 -------------------------------------
407 0.3.0 (2008-01-12) "solar saturation"
408 -------------------------------------
410 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
413 Usually one might expect lots of new features AND a big increase in size
414 for a major release like this.
416 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
417 ever. The decrease in size is mostly due to the removal of some
418 graphical tools (which were only quick hacks anyway). But also the
419 fact that the mysql code is gone cuts down the size a bit.
421 Being independent of mysql comes at a cost: The fact that paraslash
422 now contains its own database (the object storage layer, osl) increases
423 the (stripped) binary size of para_server by ~50K on i386.
425 - no more restrictions on unique basenames.
426 - independent of mysql: The new self-contained object
427 storage layer (osl) replaces the mysql database.
428 - New executable para_fsck: Check integrity of osl tables.
430 - Reliable audio file move/rename detection.
431 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
432 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
434 - the new osl-based audio file selector (afs) replaces the random,
435 the playlist and the mysql selector of paraslash-0.2.x.
436 - IPv6 support (thanks to Gerrit Renker).
437 - paraslash-0.2.x streams are now called "moods". Writing
438 0.3.x-mood definitions should be both easier and more
439 powerful than writing 0.2.x-stream definitions.
440 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
441 been removed. The world is a better place without them. However,
442 para_gui is still there.
443 - afs tracks audio file selection also in playlist mode.
444 - few easy-to-use afs commands replace the many not-so-easy-to-use
445 mysql commands (and are available also in playlist mode).
446 - Improved error subsystem.
447 - The earth-shaking new logo.
449 -----------------------------------------
450 0.2.17 (2007-11-20) "isotropic threshold"
451 -----------------------------------------
453 Mainly bugfixes and cleanups in this version which marks the end of
454 the 0.2.x series if no serious bugs show up after the release.
456 - mysql_selector: fix a locking bug.
457 - universal chunk queueing.
458 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
460 - be more carful wrt. signed vs. unsigned argument passing.
461 - cleanup error.h and fix some references to invalid error
463 - update to gengetopt-2.21.
464 - update to ortp-0.13.1.
465 - autoconf: extend checks for headers, library functions and
466 compiler characteristics.
467 - Fix streaming of large mp3 files.
468 - Fix an off-by-one bug in playlist handling.
470 --------------------------------------
471 0.2.16 (2007-04-05) "neural discharge"
472 --------------------------------------
474 The main change in this release is the major audio format handler
475 cleanup which removes some similar/duplicate code and makes it easier
476 to implement plugins for other audio formats. Of course, the usual mix
477 of other improvements/changes/bugfixes also made it into the release.
479 - simplified audio format handlers (most of the handling functions
480 were moved one layer up to the virtual streaming system).
481 - para_server uses mmap to read audio files
482 - repositioning of mp3 streams is much faster, in particular for
483 jumping near the end of large mp3 files.
484 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
486 - fix a bug in para_filter that caused decoding of aac files
487 to start only after a few seconds.
488 - fix osx_writer hangs
489 - simplified dccp code (thanks to Gerrit Renker)
490 - the compress filter works also on big endian systems (ppc)
492 -----------------------------------------
493 0.2.15 (2007-02-16) "inductive resonance"
494 -----------------------------------------
496 Minor improvements, more documentation and a bunch of bug fixes.
498 - para_server: The server.users file is only read once on server
499 startup rather than for each connection
500 - mp3dec: Fix decoding of corrupt mp3 files
501 - afs (audio file sender) is now called vss (virtual streaming
502 system). Consequently, the permission flags specified in
503 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
504 become VSS_READ and VSS_WRITE respectively.
505 - para_audiod/para_filter: Fix a bug that caused the last chunk
506 of audio data not being written under certain circumstances
507 - audiod: compute the difference of server time and local time
509 - para_server/para_audiod: Fix some memory leaks
510 - documentation improvements
511 - configure.ac: fix checks for para_krell
514 -------------------------------------------
515 0.2.14 (2006-10-15) "transient singularity"
516 -------------------------------------------
518 The only major enhancement of this version is the osx writer which completes
519 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
520 until now for reasons beyond the scope of this changelog entry.
522 - new output plugin for Mac Os: the osx writer
523 - rename configure command line options from --enable-xxx-headers to
524 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
525 - configure: new command line options: --with-mad-headers,
526 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
527 - some robustness fixes
528 - dymamic audio format recognition for audiod
529 - para_server: new command line option: --autoplay_delay
530 - para_audiod: new command line option: --clock_diff_count
532 ---------------------------------------
533 0.2.13 (2006-07-14) "sonic convolution"
534 ---------------------------------------
536 A bunch of new features and core changes.
538 - the new paraslash scheduler, short and sweet.
539 - Support for m4a/mp4 files via the new aac audio format
540 handler/filter (requires libfaad).
541 - each writer has its own command line parser, just like
542 para_recv and para_filter.
543 - para_client and para_audioc use the error subsystem
544 - writers are integrated in para_audiod (currently linux-only)
545 - para_client is integrated in para_audiod
546 - random/playlist selector: improved info strings
547 - new audiod commands: tasks, kill
548 - update to libortp-0.10.1
549 - para_fade: wake time defaults to 8 hours from now
550 - update to autoconf-2.60
552 ------------------------------------------
553 0.2.12 (2006-05-12) "oriented abstraction"
554 ------------------------------------------
556 Many user-visible changes in this release and lots of new
560 - the new optional dccp sender/receiver. It uses the datagram
561 congestion control protocol. You'll need a fairly new kernel
563 - paraslash works on Mac OS X (thanks to Gerd Becker)
564 - para_play renamed to para_write
565 - modular output plugin design (writers) for para_write
566 - new file_writer output plugin for para_write
567 - compress filter speed improvements
568 - update to libortp-0.9.1
569 - update to gengetopt-2.17rc
570 - para_client no longer depends on libreadline (as the
571 code for the interactive mode was removed).
572 - gcc-2-95 is no longer a supported compiler. It may still
573 work, but it gets no more testing.
574 - the tarball no longer contains the screenshot images which
575 reduces its size quite a bit.
576 - configure: new command line options: --enable-mysql-headers
577 and --enable-mysql-libs
579 ------------------------------------
580 0.2.11 (2006-03-11) "atomic duality"
581 ------------------------------------
583 Here it is, the first paraslash release developed with git. There
584 are fairly many user-visible changes in this release. As two out of
585 the three "database tools" of paraslash don't use a database at all,
586 they are now called "audio file selectors" instead.
589 - the cdt command (change database tool) becomes chs (change
591 - no more colon separators: The syntax of some options of
592 para_audiod and para_filter have changed. Use --help for
593 more info (and some examples).
594 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
595 - switch from cvs to git (should've done that earlier)
596 - the new ipc subsystem
597 - new audio file selector: playlist
598 - para_server: the dopey selector is now called "random",
599 and is the default selector. Use the --selector option to
600 choose another selector at startup, or the chs command to
601 change the selector at runtime.
602 - X86_64 fixes (thanks to Steffen Klassert)
605 --------------------------------------
606 0.2.10 (2006-02-17) "cyclic attractor"
607 --------------------------------------
609 Huge documentation update, a scrollable window for para_gui, ortp
610 improvements, and of course many small fixes not mentioned here.
611 The diffstat below is rather misleading as most insertions are due
612 to the new source documentation.
615 - para_server also uses the new error subsystem
616 - lots of new documentation (UTSL)
618 - keysyms for cursor keys and for next/previous page keys
619 - scrollable output window
620 - new internal commands: scroll up/down, page up/down
621 - fix color of command output.
622 - ortp: the --chunk_time and --header flags are no longer needed
623 for para_recv/para_audiod as this information is now encoded in
624 each rtp packet sent by para_server.
626 -------------------------------------------
627 0.2.9 (2006-01-24) "progressive turbulence"
628 -------------------------------------------
630 Internal audiod receivers/filters, the new error subsystem and
631 a lot of small improvements.
633 - para_recv and para_filter are integrated into the para_audiod
634 binary, i.e. audiod no longer spawns a new process for
635 each receiver/filter. As para_recv and para_filter might be
636 useful as standalone programs, they still get built (linked
637 against the same object files that are also used for audiod).
638 - further ortp timing improvements should reduce the CPU usage
639 of the ortp receiver.
640 - improved audio grabbing. The 'grab' command of para_audiod
641 has its own set of command line options. Read the output of
642 "para_audioc help grab" for more info.
643 - oggdec: configurable input prebuffer size.
644 - the new error subsystem gives better error diagnostics
645 and reduces code size.
647 -----------------------------------------
648 0.2.8 (2006-01-02) "dynamic accumulation"
649 -----------------------------------------
651 The new modular filter design and the para_play-hangs bugfix.
653 - new executable: para_filter. It combines para_mp3dec,
654 para_oggdec and para_compress. It also adds a further filter
655 type, wav, that just inserts a wave header at the desired point
656 of the filter chain. All 'piping' is done in-memory (i.e. no
657 read/write operations are used).
658 - para_play: fix a stupid bug that caused it to hang under
659 certain circumstances.
661 -------------------------------------------
662 0.2.7 (2006-12-27) "transparent invariance"
663 -------------------------------------------
665 Not many user-visible changes but a fair amount of internal improvements.
668 - The http sender buffers data if it can not be sent
669 out immediately (because the socket is not writable). This
670 should prevent para_server from shutting down the connection
671 too early on a loaded network.
672 - para_play also prebuffers data if it is told to start at a
673 future time by the --start_time option.
674 - The return of para_recv: It combines para_ortp_recv and
675 para_http_recv. Use the --receiver option to switch between
676 the two. para_recv builds without libortp, but contains
677 only the http receiver in this case.
678 - update to ortp 0.8.1. As this ortp release contains incompatible
679 changes, para_recv-0.2.7 won't link against older ortp libs.
680 - improved ortp timings.
681 - use of gcc-extensions that #define away for non-gcc and
684 -------------------------------------------
685 0.2.6 (2005-10-29) "recursive compensation"
686 -------------------------------------------
688 Transparent session encryption (uses openssl's Alleged RC4 cipher),
689 the internal find command and several other improvements and cleanups.
691 - Encrypt the session if encryption is requested by the client
692 (default for para_client 0.2.6). This is backwards
693 compatible, so older clients can still connect to para_server
694 0.2.6. Use the new client option --plain to request an
695 uncrypted session (off by default, must be set to on in
696 order to connect to para_server 0.2.x with 0 <= x <= 5).
697 - para_server uses an internal function to locate audio files
698 rather than calling find(1). The server option
699 --mysql_audio_file_dir replaces --mysql_find_cmd.
700 - documentation update
702 - header file cleanup
703 - para_client code cleanup
704 - para_gui: faster display of output of display commands
706 ------------------------------------------
707 0.2.5 (2005-10-13) "aggressive resolution"
708 ------------------------------------------
710 This release adds internal senders, i.e. no more external programs are
711 spawned for sending out the audio data. There are two different senders
712 available: The http sender and the ortp sender (former para_send which
713 is no longer needed).
715 The new sender code has a plugin-like design so it can be easily
716 extended should there be be any future need for supporting another
717 network streaming protocol. All senders are completely independent of
718 each other. In particular, the http and the ortp sender can operate
721 - new server command: sender to control senders at runtime.
722 Read the output of "para_server -h" and "para_client help
723 sender" for more information.
724 - para_recv renamed to para_ortp_recv
725 - new executable: para_http_recv, a simple command line
727 - major afs/mp3/ogg code simplifications due to internal
729 - ogg timing improvements
730 - fix several minor memory leaks (found by valgrind)
731 - empty stream definitions work again
732 - com_ne(): ignore errors on remove
733 - audiod: fix segfault on server restart
735 ---------------------------------------
736 0.2.4 (2005-09-21) "toxic anticipation"
737 ---------------------------------------
739 Several small improvements, fixes and the new grab command.
742 - new command: "grab" to grab the output of the stream reader
743 or any filters. Read the output of "para_audioc help grab"
744 for more information.
747 - audioc: new command line option: --bufsize to specify a
748 buffer size different from the default size 8192.
749 - improved error diagnostics for para_play.
750 - new configure option: --enable-ssldir so search for openssl in
752 - sdl_gui: Make it look nice again for 1024x768
753 - server: report total size of memory allocated with sbrk by malloc,
754 new command line option: --announce_time
756 -----------------------------------------
757 0.2.3 (2005-09-01) "hydrophilic movement"
758 -----------------------------------------
760 Two new executables and major feature enhancements.
762 - audiod filters: It is now possible to specify arbitrary many
763 (including none) filters for each supported audio
764 format. This can be used e.g. for normalizing volume,
765 transforming or grabbing the audio stream, or for using
766 visualizers. Read the output of "para_audiod -h" for the
767 syntax of the new --filter_cmd option.
768 - new executable: para_play, a tiny alsa player. It
769 can play wave files or raw pcm (16 bit little endian)
771 - new executable: para_compress, a dynamic range compressor
772 intended to keep audio output at a consistent volume. Derived
773 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
774 - audiod: New option: --stream_delay. This can be used in
775 a local network to syncronize the audio output of all
776 clients that play the same stream.
778 ------------------------------------------
779 0.2.2 (2005-08-19) "tangential excitation"
780 ------------------------------------------
782 Mostly internal changes in this release, but also some new commands
783 for the mysql database tool.
785 - cleanup exec.c, fix para_exec bug
786 - compile time loglevel (log messages below the given level
787 won't be compiled in, which reduces the size of the
789 - new log macros that shorten the size of the source code.
790 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
791 to send only zeros. With this workaround, para_audioc works
793 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
794 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
795 (new entry), "snp" (set numplayed). Read the manual for more
798 ---------------------------------------
799 0.2.1 (2005-08-15) "surreal experience"
800 ---------------------------------------
802 Here comes paraslash-0.2.1. It contains a couple of new features and,
803 surprise, only minor bug fixes.
805 - kill noisy mp3 debug message
806 - cleanup of the build system
807 - para_server and para_client directly use the crypto routines
808 of the openssl library rather than invoking the openssl command
810 - server/audiod: new option --user to switch to the given user
811 when invoked as root. Read the output of "para_server -h" for
813 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
814 status. Default: "para_audioc stat"
815 - sdl_gui: new option --pic_cmd to be used to download the picture.
816 Default: "para_client pic"
817 - audiod: 5 slots ought to be enough for everybody
818 - audiod: new status item: Uptime, kill hup command
820 ------------------------------------------
821 0.2.0 (2005-08-06) "distributed diffusion"
822 ------------------------------------------
824 After several month of increased development activity, paraslash-0.2.0
825 has arrived. It contains many new features and is much more
826 self-contained than the old 0.1.x series. Enjoy!
829 - para_server: fix hang on song change and crash on sighup.
830 Speed up mysql queries. The DIR_LIKE macro is gone.
831 - new executables: para_audiod, the local audio daemon that
832 starts playback (uses SCM_CREDENTIALS socket magic) and
833 para_audioc, the corresponding client.
834 - new executables: para_mp3dec/para_oggdec, two really teensy
835 decoders. para_mp3dec is based on libmad, para_oggdec requires
837 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
838 they are now called para_send and para_recv respectively.
839 - documentation updates
840 - para_gui is themable. For now there is the default theme that
841 looks as before and the simple theme: blue and easy.
842 - gui: audio streaming is now handled by audiod. Time display shows
843 playback time rather than streaming time
844 - slider: update to libzmw-0.2.0
845 - para_krell: fix crash on server shutdown
846 - switch from gzip to bzip2
848 ----------------------------------------
849 0.1.7 (2005-04-18) "melting penetration"
850 ----------------------------------------
852 The main change in this release is clearly the oggvorbis rewrite,
853 but there are also lots of smaller changes. If you intend to use both
854 the mp3 and the ogg plugin, it is recommended to use software mixing,
855 e.g. the dmix plugin which is provided by ALSA.
857 - new executables: para_ovsend and para_ovrecv for sending/receiving
858 oggvorbis files via rtp. Requires the open rtp library. Get it at
859 http://www.linphone.org/ortp/
860 - rewrite of the ogg_vorbis core code
861 - configure detects libzmw and, if detected, includes
862 para_slider to the list of binaries to be built by make
863 - server stream writers read from their associated fifo rather
865 - slider: two new sliders, lastplayed and numplayed
866 - fix nasty double free bug which caused random segfaults in case of
867 mp3 files with invalid header information
868 - gui: new command line option: --stream_timeout=seconds to
869 deactivate a slot if it is idle for that many seconds (default=`5')
872 ---------------------------------------
873 0.1.6 (2005-03-05) "asymptotic balance"
874 ---------------------------------------
876 Only little user-visible changes in this release. Mainly bugfixes and
877 core code cleanup. This is probably the most stable version ever if you
880 - fix several memory leaks
881 - rename default name of mysql database from "music" to "paraslash".
882 Use para_server's --mysql_database option if you do not want to
883 rename your old database.
884 - rework ogg vorbis code
885 - make update command work on mysql servers with LOCAL_INFILE
887 - gui: improved stream I/O (slots)
888 - simplified audio format API
889 - para_pob_ogg is gone
891 ------------------------------------
892 0.1.5 (2004-12-31) "opaque eternity"
893 ------------------------------------
895 Let's slide gently into the new year.
897 - new: para_slider (not built automatically, type "make
898 para_slider" to build). A toy for those who always felt that
899 creating stream definitions is difficult. See screenshots,
900 README and FEATURES for more info.
901 - improved signal handling. Fixes server segfault on SIGHUP
902 for linux kernels newer than Aug 24 2004 and makes para_gui
904 - reload database tool on SIGHUP
905 - improved help message for sl
906 - do not log "broken pipe" messages as errors. They are
908 - fix wrong error message on permission errors
910 -----------------------------------------
911 0.1.4 (2004-12-19) "tunneling transition"
912 -----------------------------------------
914 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
915 Hopefully, most of them got wiped out with this release. Some
916 enhancements went also in.
918 - improved error diagnostics for all commands
919 - stradd/picadd: overwrite previous contents if entry already
920 exists, rather than returning errors
921 - stradd: use current stream if invoked without args
922 - faster (and hopefully more stable) ogg-vorbis handling
923 - para_krell: reap children to avoid zombie-flooding in case
925 - si: report also server pid
926 - server: don't busy-loop if dbtool reports only invalid files.
927 - gui: CTRL+C works again, fix stream_read command line option
929 - fix mysql dbtool startup in case no database exists
930 - many small fixes and cleanups
932 ---------------------------------------
933 0.1.3: (2004-12-10) "vanishing inertia"
934 ---------------------------------------
936 Starting from this release, the database tools are integrated in the
937 server binary. This decreases server startup time, reduces code size
938 and speeds up database commands. However, the layout of the underlying
939 mysql database changed only slightly and 0.1.3 should be backwards
940 compatible in that respect.
944 - If mysql is not detected at compile time, or fails to init
945 at runtime, fall back to the dopey database tool which should
947 - para_dbtool and dbtool.conf are gone. All mysql specific
948 options are read from server.conf and are prefixed by 'mysql_'.
949 - new command: cdt (change database tool)
950 - new command line option: dbtool (choose startup database tool)
951 - The name of current stream is now stored in the database,
952 so paraslash remembers its current stream when restarted.
953 - new command: csp (change stream and play)
954 - para_gui also reports current database tool and server uptime
956 -------------------------------------------
957 0.1.2: (2004-11-28) "spherical fluctuation"
958 -------------------------------------------
960 Point release before the big dbtool changes go in.
962 - dbtool: rename ca to cam (copy all meta data). It now also
963 copies numplayed and lastplayed time as well as the picture
965 - fix endless-loop-bug caused by mp3 files with invalid header
967 -----------------------------------------
968 0.1.1: (2004-11-05) "floating atmosphere"
969 -----------------------------------------
972 - new dbtool command: mbox. Browse your sound-file collection
973 with your favorite mail reader.
974 - several small fixes
976 -------------------------------------
977 0.1.0: (2004-10-22) "rotating cortex"
978 -------------------------------------
980 - fix logging bug for loglevel > VERBOSE
982 - correct timings for vbr mp3s
983 - modular audio format support
984 - ogg-vorbis support (experimental)
985 - new server option: autoplay
987 -----------------------------------------
988 0.0.99: (2004-07-25) "harmonic deviation"
989 -----------------------------------------
991 - rename projectname from icc to paraslash (play, archive, rate
992 and stream large audio sets happily)
993 - paraslash is no longer restricted to one particular audio
995 - new dbtool commands (stradd, strq, strdel) for easy stream
996 managment w/o configuration file. That obsoletes stream_defs
997 file/config option for dbtool.
998 - picadd accepts jpeg data from stdin
999 - new server commands: ps (select previous stream), sc (song change)
1000 - new default pictures for sdl_gui
1001 - gui: new key_map option for binding commands and internal
1002 functions to arbitrary keys, nice help screen, rip out
1003 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1004 show silly logo on startup
1005 - new executables: para_fade for fading volume, para_dbadm for
1006 manipulating attributes
1007 - cdb adds _all_ tables to mysql database
1008 - revised and beautified documentation
1009 - sample dbtool rewritten in C
1012 ---------------------------------------------
1013 0.0.98: (2003-12-26) "incremental smoothness"
1014 ---------------------------------------------
1016 - kick icecast in favour of poc. That removes some races and reduces
1017 core code considerably.
1018 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1019 give finer info on afs' status.
1020 - gui can start decoder (see config options). Further new gui
1021 commands: refresh (^L), jmp (F1-F10)
1022 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1023 terminates gui. This fixes dead instances consuming memory
1025 - new dbtool command: verb for sending verbatim sql queries.
1026 - fix pid_list races (by removing pid_list)
1029 --------------------
1030 0.0.97: (2003-10-26)
1031 --------------------
1033 - installation prefix now defaults to /usr/local
1034 - new commands for gui: snozze, sleep and reread config
1035 - config file for gui and sdl_gui
1036 - fix problems with filenames containing funny characters
1037 (reported by Thomas Forell)
1038 - improved signal handling for gui, now it rereads conf on SIGHUP
1039 - new dbtool command: cdb (create database)
1040 - switch from argtable to gengetopt
1041 - major code cleanup and speed improvements
1042 - fix several potential buffer overflows
1043 - many small fixes and cleanups
1049 - easy stream_defs syntax
1050 - sdl_gui can display images associated to the file being played
1051 - Major feature enhancements for icc_gui including dynamic text
1052 placement and the top/bottom window design
1053 - vrfy/clean now also checks for NULL values in attributes as
1054 well as for invalid picture pointers
1055 - fix long outstanding case sensitivity bug
1056 - many small fixes and cleanups
1062 - sdl gui runs much faster
1063 - new dbtool command: ca (copy attributes)
1064 - count and display number of times the song has been played
1065 - new feature: scoring
1066 - command line options for sdl_gui
1067 - simpler syntax of streams file
1068 - decrease network traffic of stat
1070 - many small fixes and cleanups
1076 - new server command: ns (next stream)
1077 - new icc_gui command: c (change stream)
1079 - stat shows also id3 tag info
1081 - log flodding bug fixed
1082 - many small fixes and cleanups
1088 - colors for icc_gui
1089 - icc_gui sets volume directly (linux only)
