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.
9 - Speed and usability improvements for para_gui.
10 - para_client now restores the fd flags of stdin and stdout
12 - Improved manual pages.
13 - Consistent version strings for all executables.
14 - Reduced depencies on generated files result in fewer
15 recompilations on changes.
16 - Performance improvements for the compress filter.
17 - Improved downloads web page.
19 -----------------------------------------
20 0.4.12 (2012-12-20) "volatile relativity"
21 -----------------------------------------
22 The new command line player, the resample filter, ALSA support for
23 para_fade, and the improved build system are the highlights of this
24 release which probably marks the end of the 0.4.x series.
26 - The afh receiver and the para_play executable.
27 - The resample filter: A sample rate converter based on
29 - The "versions" directory has been removed from the master
30 branch. The tarballs of the old releases are now available
31 in the new "releases" branch.
32 - Overhaul of the build system: All generated files are now
33 written to the "build" directory.
34 - The modular mixer API and the alsa mixer.
35 - Minor fixes for the osx writer.
37 --------------------------------------
38 0.4.11 (2012-07-20) "mutual diversity"
39 --------------------------------------
41 The major feature in this release is the new sideband API for
42 client-server communication. This API will be used exclusively starting
43 with 0.5.0, which breaks backward compatibility but allows to get rid
44 of quite some compatibility code. Other noteworthy changes include
45 decoder latency improvements and a long-standing bug fix for the
48 - Sideband connections: If both para_server and para_client
49 support this feature, data is sent as a multiplexed stream.
50 - The --no_default_filters option of para_filter has been
52 - Several fixes and latency improvements to various decoders.
53 - The ALSA writer now limits the prebuffer time to 500ms.
54 - Documentation improvements.
55 - Overhaul of the command_util.sh script.
56 - Fixes for some minor problems found by the clang analyzer.
57 - Compiles (almost) without warnings on gcc-3.
58 - Robustness improvements of the buffer tree code.
60 ------------------------------------------
61 0.4.10 (2012-03-30) "heterogeneous vacuum"
62 ------------------------------------------
64 Nothing earth-shaking in this release, but quite a few usability
65 improvements and the usual mix of cleanups and fixes.
67 - The --no_default_filters option of para_filter has been
68 deprecated. It still works but has no effect and will be
69 removed in the next version.
70 - para_gui now prints also the stderr output of the executing
71 command in the bottom window.
72 - Cleanup and consolidation of the various wrappers for
73 write(), writev(), send() and friends.
74 - The obscure error messages on mmap() failures have been
75 replaced by meaningful messages. This affects mainly
77 - para_audioc: Cleanups and memory leak fixes.
78 - Test 0004-server no longer fails if para_server is not
80 - New configure options: --with-id3tag-{headers,libs}.
82 -------------------------------------
83 0.4.9 (2011-12-06) "hybrid causality"
84 -------------------------------------
86 Support for another audio format, interactive mode for para_client
87 and para_audiod and many small improvements/fixes all over the place.
89 - Support for flac, the free lossless audio codec.
90 - Fix for an endless loop in the mp3 decoder for certain
92 - When executed without specifying a command, para_client
93 and para_audioc start an interactive shell (requires
94 libreadline being installed). The interactive mode offers
95 full tab completion and command line history.
96 - autogen.sh now detects a distcc setup and adjusts the
97 parameter for the -j option of make accordingly.
98 - Shared memory areas are no longer restricted to 64K. We now
99 detect the maximal size of a shared memory area at runtime.
100 - cleanup of the internal uptime API.
101 - para_server prefaults the mmapped audio file to avoid
102 delays on slow media.
103 - A new test for the test-suite that exercises the
104 communication between para_server and para_audiod.
105 - The alsa writer eats up less CPU cycles when configured to
107 - Simplified and unified receiver code.
109 - Commands which print a list of matching audio files now
110 emit a meaningful error message if no audio file matched the
113 --------------------------------------
114 0.4.8 (2011-08-19) "nested assignment"
115 --------------------------------------
117 Gcrypt support, the overhauled osx writer and regex format specifiers
118 are the highlights of this release.
120 - support for libgcrypt as a drop-in replacement for openssl.
121 Run configure --enable-cryptolib=gcrypt to link against
122 libgcrypt. The two crypto implementations are compatible to
123 each other, i.e. a para_client executable linked against
124 gcrypt can connect to para_server linked against libssl
126 - Rewrite of the osx writer (output plugin for Mac OS).
127 - audiod: The format specifier for receivers, filters and
128 writers is now treated as a regular expression. This allows
129 to replace 5 lines in the config file (one for each audio
130 format) by one single line. See the manual for details.
131 - The *.cmdline.[ch] files are no longer contained in the released
132 tarballs. This reduces the size of the tarballs but requires
133 gengetopt to build the tarball.
134 - Compiles cleanly also with llvm/clang.
135 - Corrupt mp3 files are handled more gracefully.
136 - The alsa writer uses poll fds instead of computing timeouts.
137 - Cleanup of the generic writer API.
138 - sched: Optimized zero timeouts.
139 - vss timeout cleanups.
140 - oggdec fixes and improvements.
142 --------------------------------------
143 0.4.7 (2011-06-01) "infinite rollback"
144 --------------------------------------
146 The new ao writer, support for ssh RSA keys and a couple of other
149 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
150 platforms through the libao audio library.
151 - Support for RSA keys generated with ssh-keygen.
152 - configure: improved options for ogg/vorbis/speex.
153 - The git version reported by --version always matches HEAD.
154 - The autogen script detects the number of processors and
155 runs a parallel make if possible.
156 - Major cleanup of the crypto API.
157 - Documentation updates.
159 ------------------------------------------
160 0.4.6 (2011-03-31) "deterministic entropy"
161 ------------------------------------------
163 Lots of ogg/vorbis improvements, the new test suite, enhancements
164 for para_gui and a fair amount of other bug fixes.
166 - For DCCP/OGG streams the audio file header is only sent once
167 at the beginning of the stream rather than periodically
168 every five seconds. This reduces network traffic and the
170 - The vorbis comment header is replaced by an empty dummy header
171 before the header is sent over the network. This also results in
172 less network traffic and smaller FEC groups.
173 - The new "test" make target allows to perform some sanity checks prior
174 to installing the package.
175 - ogg timing fixes and performance improvements
176 - Scheduler improvements
177 - Proper exit codes for para_write
178 - para_gui: New option --theme to select a startup theme. Several
179 other improvements and fixes.
180 - aacdec error message cleanups
181 - simplified color error handling
183 --------------------------------------------
184 0.4.5 (2010-12-17) "symmetric randomization"
185 --------------------------------------------
187 Bug fixes, internal cleanups and variable-sized FEC slices.
189 - Contains a fix for an invalid-free-bug in the ogg audio format
191 - Switching off the DCCP sender works again.
192 - para_audiod handles crashes of para_server more robustly.
193 - Internal scheduler and writer cleanups.
194 - Reduced latency due to variable-sized FEC slices.
195 - Improved documentation and error diagnostics.
196 - The build of para_server is now optional, allowing the build
197 to succeed in case libosl is not installed.
199 ------------------------------------------
200 0.4.4 (2010-08-06) "persistent regularity"
201 ------------------------------------------
203 Support for yet another audio format, para_write improvements and
206 - Support for the speex codec.
207 - Support for sample formats other than 16 bit little endian.
208 - error2.h is now created by a perl script which speeds up configure
210 - Fix a bug in the aac decoder which could lead to segfaults in
211 para_filter/para_audiod.
212 - Fixes for autoconf-2.66.
214 ----------------------------------------
215 0.4.3 (2010-07-05) "imaginary radiation"
216 ----------------------------------------
218 Many improvements for the DCCP and the UDP transport, the new user
219 manual and the usual mix of bug fixes and internal improvements.
221 - FEC support for the DCCP sender (Gerrit Renker). The new
222 --dccp_max_slice_size, --dccp_data_slices_per_group and
223 --dccp_slices_per_group options can be used to set the FEC
224 parameters for the DCCP transport.
225 - DNS lookups for UDP targets (Gerrit Renker).
226 - The new user manual replaces the README, README.afs, REQUIREMENTS
227 and INSTALL documents.
228 - Fix an end-of-file detection bug in the oggdec filter.
229 - The new nonblock API.
230 - Both options of the oggdec filter have been removed.
231 - New debug mode for the internal scheduler.
233 ------------------------------------------
234 0.4.2 (2010-04-23) "associative expansion"
235 ------------------------------------------
237 It's been some time since the last release, but finally here is
238 paraslash-0.4.2. The bulk of the changes comes from the new buffer
239 tree API, but there are changes all over the tree. Mainly performance
240 and usability improvements, but also quite some bug fixes.
242 - The new buffer tree API.
243 - DCCP: Support for CCID negotiation (Gerrit Renker).
244 - UDP robustness fixes.
245 - The --bufsize option for mp3dec is gone as it no longer makes sense
246 for the new buffer tree API.
247 - Fix audible buffer underruns for wma streams.
248 - The alsa writer no longer prints meaningless underrun durations.
249 - audiod: Defaults work also for udp streams. If no filter is
250 given for an audio format that is received via upd, fecdec is
251 automatically added as the first filter (along with the decoder).
253 ---------------------------------------
254 0.4.1 (2009-12-22) "concurrent horizon"
255 ---------------------------------------
257 Support for another audio format, minor feature enhancements and lots of bug
258 fixes. All fixes that have been accumulated in the maint branch (in particular
259 those mentionened in the 0.3.6 release notes) appear in this release as well.
262 - new afh option: --human to activate human-readable output.
263 - new server/audiod option: --log-timing to print timing information.
264 - build system improvements.
265 - source code documentation updates.
267 -------------------------------------
268 0.3.6 (2009-12-07) "cubic continuity"
269 -------------------------------------
271 Quite a few bugs have been found and fixed since 0.3.5, so here's
272 another 0.3.x release. No new features.
274 - Always check return value of malloc().
275 - ogg vorbis/FEC: Do not write garbage after the audio file header.
276 - exit if root privileges could not be dropped.
277 - FEC: Fix computation of extra slices.
278 - oss: Fix check for empty input buffer.
279 - Avoid buffer underruns due to filter chain output buffer constraints.
280 - server: Fix assignment of afs_pid.
281 - Don't panic if the afs database contains unknown audio formats.
282 - http/dccp: Do not send the audio file header twice.
283 - FEC: Timing improvements.
285 ----------------------------------------------
286 0.4.0 (2009-11-10) "simultaneous independence"
287 ----------------------------------------------
289 Two significant changes which require the new version number: The
290 improved authentication dialog and the fact that the database code
291 has been moved to a library, libosl. To use the new version, you have
292 to generate new RSA keys, see INSTALL for details. A shell script is
293 provided for conversion of the 0.3 database to the new 0.4 format.
295 - stronger crypto for client authentication
296 - the database code has been moved to a library
297 - improved status item handling
298 - cleanup of the build system
299 - The "-V" option now also prints the git version
300 - the new parser-friendly listing mode for the ls and stat commands
301 - mandatory rc4 encryption
302 - major audio format handler cleanups
303 - (id3,...) tags are no longer stored as a combined string in the database
304 - new mood methods: artist_matches, title_matches, comment_matches,
305 album_matches, year_maches, year.
307 --------------------------------------------
308 0.3.5 (2009-09-21) "symplectic separability"
309 --------------------------------------------
311 Full client support for *BSD Unixes, complete re-write of the ogg
312 vorbis audio format handler, various improvements all over the place
313 and the usual mix of bugfixes. This release marks the end of the 0.3
314 series if no serious problems show up.
316 - the new oss writer (supported on *BSD and Linux)
317 - rewrite of the ogg vorbis audio format handler. It's
318 recommended to replace the chunk tables of existing ogg
319 vorbis files in the afs database by re-adding these files
321 - support for netmask subsets (Gerrit Renker)
322 - the new prebuffer filter
323 - improved signal handling
324 - variable fec output buffer size
325 - improved FEC timing fixes audible buffer underruns in UDP mode
326 - --log_color actually works
327 - new ls option: -d (print dates as seconds after the epoch)
328 - update to gengetopt 2.22.2
329 - support for RSA keys of size > 512 bits
330 - new option "mixer_channel" for para_fade
332 -----------------------------------------
333 0.3.4 (2009-05-07) "elliptic inheritance"
334 -----------------------------------------
336 The new udp sender, forward error correction, colored logs and various
337 other improvements. As the udp sender does not depend on any special
338 libraries, it is built unconditionally.
340 - The udp sender replaces the ortp sender. The new code uses forward
341 error correction to protect against packet losses. Many thanks to
342 Gerrit Renker for providing ipv6 support.
343 - The default port for udp streaming now defaults to 8000, like
344 for the http and the dccp senders/receivers.
345 - Loglevels are now specified as symbolic names, e.g.
347 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
348 - para_server/para_audiod: Color support for log messages.
349 - new options for mp3dec: --ignore-crc, --bufsize
350 - new audiod option: --config-file.
351 - gengetopt cleanups.
352 - Improved help/man pages: The documentation of para_audiod,
353 para_recv, para_filter and para_write now also contains
354 all options of the available receivers/filters/writers. The
355 man page of para_fade contains a description of the different
357 - More source code documentation.
360 --------------------------------------------
361 0.3.3 (2008-12-01) "axiomatic perspectivity"
362 --------------------------------------------
364 Internal code cleanups, bug fixes, improved tag handling and the new
365 amplification filter.
367 - para_server uses the generic scheduling code.
368 - overhaul of the virtual streaming system.
369 - mp3: id3 version 2 support via libid3tag (optional)
370 - ogg: vorbis comment support.
371 - aac meta info support.
372 - mp3 audio format handler cleanups.
373 - new filter: "amp" to amplify the amplitude of the audio stream
374 - new status item/database entry: amplification. It is
375 used by the amp filter to pre-amplify the audio stream.
376 - fix a close-without-open bug in para_write.
377 - fix a bug in com_init() which was introduced in 0.3.2.
378 - better error diagnostics for para_client.
380 -----------------------------------------
381 0.3.2 (2008-04-11) "probabilistic parity"
382 -----------------------------------------
384 The new para_afh executable, scheduling and documentation improvements.
386 - new ls option: -lc (list chunk table)
387 - new executable: para_afh, the stand-alone audio file handler tool
388 - afs commands can send output more than SHMMAX (32MB on Linux). This
389 also reduces the memory usage of commands that produce large amounts
391 - major scheduler and audiod cleanups.
392 - more detailed and much nicer man pages.
394 ---------------------------------------
395 0.3.1 (2008-02-23) "liquid interaction"
396 ---------------------------------------
398 A mix of cleanups, bug fixes, improvements, and some new features. No
399 significant changes to the new database (osl) code, which is generally
402 - Share some similar/duplicate code between the http and the
404 - Generic access control lists for paraslash senders.
405 - dccp sender: Access control lists, connection limiting and support
406 for the allow,deny,on,off,help sender commands.
407 - The default dccp port changed from 5001 to 8000 (suggested by
409 - para_server starts even if not all public keys could be loaded.
410 - Audiod performance improvements.
411 - fix a bug in the "off" command of the http sender.
412 - fix some fd and memory leaks.
413 - Update to gengetopt-2.22.
415 -------------------------------------
416 0.3.0 (2008-01-12) "solar saturation"
417 -------------------------------------
419 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
422 Usually one might expect lots of new features AND a big increase in size
423 for a major release like this.
425 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
426 ever. The decrease in size is mostly due to the removal of some
427 graphical tools (which were only quick hacks anyway). But also the
428 fact that the mysql code is gone cuts down the size a bit.
430 Being independent of mysql comes at a cost: The fact that paraslash
431 now contains its own database (the object storage layer, osl) increases
432 the (stripped) binary size of para_server by ~50K on i386.
434 - no more restrictions on unique basenames.
435 - independent of mysql: The new self-contained object
436 storage layer (osl) replaces the mysql database.
437 - New executable para_fsck: Check integrity of osl tables.
439 - Reliable audio file move/rename detection.
440 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
441 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
443 - the new osl-based audio file selector (afs) replaces the random,
444 the playlist and the mysql selector of paraslash-0.2.x.
445 - IPv6 support (thanks to Gerrit Renker).
446 - paraslash-0.2.x streams are now called "moods". Writing
447 0.3.x-mood definitions should be both easier and more
448 powerful than writing 0.2.x-stream definitions.
449 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
450 been removed. The world is a better place without them. However,
451 para_gui is still there.
452 - afs tracks audio file selection also in playlist mode.
453 - few easy-to-use afs commands replace the many not-so-easy-to-use
454 mysql commands (and are available also in playlist mode).
455 - Improved error subsystem.
456 - The earth-shaking new logo.
458 -----------------------------------------
459 0.2.17 (2007-11-20) "isotropic threshold"
460 -----------------------------------------
462 Mainly bugfixes and cleanups in this version which marks the end of
463 the 0.2.x series if no serious bugs show up after the release.
465 - mysql_selector: fix a locking bug.
466 - universal chunk queueing.
467 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
469 - be more carful wrt. signed vs. unsigned argument passing.
470 - cleanup error.h and fix some references to invalid error
472 - update to gengetopt-2.21.
473 - update to ortp-0.13.1.
474 - autoconf: extend checks for headers, library functions and
475 compiler characteristics.
476 - Fix streaming of large mp3 files.
477 - Fix an off-by-one bug in playlist handling.
479 --------------------------------------
480 0.2.16 (2007-04-05) "neural discharge"
481 --------------------------------------
483 The main change in this release is the major audio format handler
484 cleanup which removes some similar/duplicate code and makes it easier
485 to implement plugins for other audio formats. Of course, the usual mix
486 of other improvements/changes/bugfixes also made it into the release.
488 - simplified audio format handlers (most of the handling functions
489 were moved one layer up to the virtual streaming system).
490 - para_server uses mmap to read audio files
491 - repositioning of mp3 streams is much faster, in particular for
492 jumping near the end of large mp3 files.
493 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
495 - fix a bug in para_filter that caused decoding of aac files
496 to start only after a few seconds.
497 - fix osx_writer hangs
498 - simplified dccp code (thanks to Gerrit Renker)
499 - the compress filter works also on big endian systems (ppc)
501 -----------------------------------------
502 0.2.15 (2007-02-16) "inductive resonance"
503 -----------------------------------------
505 Minor improvements, more documentation and a bunch of bug fixes.
507 - para_server: The server.users file is only read once on server
508 startup rather than for each connection
509 - mp3dec: Fix decoding of corrupt mp3 files
510 - afs (audio file sender) is now called vss (virtual streaming
511 system). Consequently, the permission flags specified in
512 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
513 become VSS_READ and VSS_WRITE respectively.
514 - para_audiod/para_filter: Fix a bug that caused the last chunk
515 of audio data not being written under certain circumstances
516 - audiod: compute the difference of server time and local time
518 - para_server/para_audiod: Fix some memory leaks
519 - documentation improvements
520 - configure.ac: fix checks for para_krell
523 -------------------------------------------
524 0.2.14 (2006-10-15) "transient singularity"
525 -------------------------------------------
527 The only major enhancement of this version is the osx writer which completes
528 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
529 until now for reasons beyond the scope of this changelog entry.
531 - new output plugin for Mac Os: the osx writer
532 - rename configure command line options from --enable-xxx-headers to
533 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
534 - configure: new command line options: --with-mad-headers,
535 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
536 - some robustness fixes
537 - dymamic audio format recognition for audiod
538 - para_server: new command line option: --autoplay_delay
539 - para_audiod: new command line option: --clock_diff_count
541 ---------------------------------------
542 0.2.13 (2006-07-14) "sonic convolution"
543 ---------------------------------------
545 A bunch of new features and core changes.
547 - the new paraslash scheduler, short and sweet.
548 - Support for m4a/mp4 files via the new aac audio format
549 handler/filter (requires libfaad).
550 - each writer has its own command line parser, just like
551 para_recv and para_filter.
552 - para_client and para_audioc use the error subsystem
553 - writers are integrated in para_audiod (currently linux-only)
554 - para_client is integrated in para_audiod
555 - random/playlist selector: improved info strings
556 - new audiod commands: tasks, kill
557 - update to libortp-0.10.1
558 - para_fade: wake time defaults to 8 hours from now
559 - update to autoconf-2.60
561 ------------------------------------------
562 0.2.12 (2006-05-12) "oriented abstraction"
563 ------------------------------------------
565 Many user-visible changes in this release and lots of new
569 - the new optional dccp sender/receiver. It uses the datagram
570 congestion control protocol. You'll need a fairly new kernel
572 - paraslash works on Mac OS X (thanks to Gerd Becker)
573 - para_play renamed to para_write
574 - modular output plugin design (writers) for para_write
575 - new file_writer output plugin for para_write
576 - compress filter speed improvements
577 - update to libortp-0.9.1
578 - update to gengetopt-2.17rc
579 - para_client no longer depends on libreadline (as the
580 code for the interactive mode was removed).
581 - gcc-2-95 is no longer a supported compiler. It may still
582 work, but it gets no more testing.
583 - the tarball no longer contains the screenshot images which
584 reduces its size quite a bit.
585 - configure: new command line options: --enable-mysql-headers
586 and --enable-mysql-libs
588 ------------------------------------
589 0.2.11 (2006-03-11) "atomic duality"
590 ------------------------------------
592 Here it is, the first paraslash release developed with git. There
593 are fairly many user-visible changes in this release. As two out of
594 the three "database tools" of paraslash don't use a database at all,
595 they are now called "audio file selectors" instead.
598 - the cdt command (change database tool) becomes chs (change
600 - no more colon separators: The syntax of some options of
601 para_audiod and para_filter have changed. Use --help for
602 more info (and some examples).
603 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
604 - switch from cvs to git (should've done that earlier)
605 - the new ipc subsystem
606 - new audio file selector: playlist
607 - para_server: the dopey selector is now called "random",
608 and is the default selector. Use the --selector option to
609 choose another selector at startup, or the chs command to
610 change the selector at runtime.
611 - X86_64 fixes (thanks to Steffen Klassert)
614 --------------------------------------
615 0.2.10 (2006-02-17) "cyclic attractor"
616 --------------------------------------
618 Huge documentation update, a scrollable window for para_gui, ortp
619 improvements, and of course many small fixes not mentioned here.
620 The diffstat below is rather misleading as most insertions are due
621 to the new source documentation.
624 - para_server also uses the new error subsystem
625 - lots of new documentation (UTSL)
627 - keysyms for cursor keys and for next/previous page keys
628 - scrollable output window
629 - new internal commands: scroll up/down, page up/down
630 - fix color of command output.
631 - ortp: the --chunk_time and --header flags are no longer needed
632 for para_recv/para_audiod as this information is now encoded in
633 each rtp packet sent by para_server.
635 -------------------------------------------
636 0.2.9 (2006-01-24) "progressive turbulence"
637 -------------------------------------------
639 Internal audiod receivers/filters, the new error subsystem and
640 a lot of small improvements.
642 - para_recv and para_filter are integrated into the para_audiod
643 binary, i.e. audiod no longer spawns a new process for
644 each receiver/filter. As para_recv and para_filter might be
645 useful as standalone programs, they still get built (linked
646 against the same object files that are also used for audiod).
647 - further ortp timing improvements should reduce the CPU usage
648 of the ortp receiver.
649 - improved audio grabbing. The 'grab' command of para_audiod
650 has its own set of command line options. Read the output of
651 "para_audioc help grab" for more info.
652 - oggdec: configurable input prebuffer size.
653 - the new error subsystem gives better error diagnostics
654 and reduces code size.
656 -----------------------------------------
657 0.2.8 (2006-01-02) "dynamic accumulation"
658 -----------------------------------------
660 The new modular filter design and the para_play-hangs bugfix.
662 - new executable: para_filter. It combines para_mp3dec,
663 para_oggdec and para_compress. It also adds a further filter
664 type, wav, that just inserts a wave header at the desired point
665 of the filter chain. All 'piping' is done in-memory (i.e. no
666 read/write operations are used).
667 - para_play: fix a stupid bug that caused it to hang under
668 certain circumstances.
670 -------------------------------------------
671 0.2.7 (2006-12-27) "transparent invariance"
672 -------------------------------------------
674 Not many user-visible changes but a fair amount of internal improvements.
677 - The http sender buffers data if it can not be sent
678 out immediately (because the socket is not writable). This
679 should prevent para_server from shutting down the connection
680 too early on a loaded network.
681 - para_play also prebuffers data if it is told to start at a
682 future time by the --start_time option.
683 - The return of para_recv: It combines para_ortp_recv and
684 para_http_recv. Use the --receiver option to switch between
685 the two. para_recv builds without libortp, but contains
686 only the http receiver in this case.
687 - update to ortp 0.8.1. As this ortp release contains incompatible
688 changes, para_recv-0.2.7 won't link against older ortp libs.
689 - improved ortp timings.
690 - use of gcc-extensions that #define away for non-gcc and
693 -------------------------------------------
694 0.2.6 (2005-10-29) "recursive compensation"
695 -------------------------------------------
697 Transparent session encryption (uses openssl's Alleged RC4 cipher),
698 the internal find command and several other improvements and cleanups.
700 - Encrypt the session if encryption is requested by the client
701 (default for para_client 0.2.6). This is backwards
702 compatible, so older clients can still connect to para_server
703 0.2.6. Use the new client option --plain to request an
704 uncrypted session (off by default, must be set to on in
705 order to connect to para_server 0.2.x with 0 <= x <= 5).
706 - para_server uses an internal function to locate audio files
707 rather than calling find(1). The server option
708 --mysql_audio_file_dir replaces --mysql_find_cmd.
709 - documentation update
711 - header file cleanup
712 - para_client code cleanup
713 - para_gui: faster display of output of display commands
715 ------------------------------------------
716 0.2.5 (2005-10-13) "aggressive resolution"
717 ------------------------------------------
719 This release adds internal senders, i.e. no more external programs are
720 spawned for sending out the audio data. There are two different senders
721 available: The http sender and the ortp sender (former para_send which
722 is no longer needed).
724 The new sender code has a plugin-like design so it can be easily
725 extended should there be be any future need for supporting another
726 network streaming protocol. All senders are completely independent of
727 each other. In particular, the http and the ortp sender can operate
730 - new server command: sender to control senders at runtime.
731 Read the output of "para_server -h" and "para_client help
732 sender" for more information.
733 - para_recv renamed to para_ortp_recv
734 - new executable: para_http_recv, a simple command line
736 - major afs/mp3/ogg code simplifications due to internal
738 - ogg timing improvements
739 - fix several minor memory leaks (found by valgrind)
740 - empty stream definitions work again
741 - com_ne(): ignore errors on remove
742 - audiod: fix segfault on server restart
744 ---------------------------------------
745 0.2.4 (2005-09-21) "toxic anticipation"
746 ---------------------------------------
748 Several small improvements, fixes and the new grab command.
751 - new command: "grab" to grab the output of the stream reader
752 or any filters. Read the output of "para_audioc help grab"
753 for more information.
756 - audioc: new command line option: --bufsize to specify a
757 buffer size different from the default size 8192.
758 - improved error diagnostics for para_play.
759 - new configure option: --enable-ssldir so search for openssl in
761 - sdl_gui: Make it look nice again for 1024x768
762 - server: report total size of memory allocated with sbrk by malloc,
763 new command line option: --announce_time
765 -----------------------------------------
766 0.2.3 (2005-09-01) "hydrophilic movement"
767 -----------------------------------------
769 Two new executables and major feature enhancements.
771 - audiod filters: It is now possible to specify arbitrary many
772 (including none) filters for each supported audio
773 format. This can be used e.g. for normalizing volume,
774 transforming or grabbing the audio stream, or for using
775 visualizers. Read the output of "para_audiod -h" for the
776 syntax of the new --filter_cmd option.
777 - new executable: para_play, a tiny alsa player. It
778 can play wave files or raw pcm (16 bit little endian)
780 - new executable: para_compress, a dynamic range compressor
781 intended to keep audio output at a consistent volume. Derived
782 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
783 - audiod: New option: --stream_delay. This can be used in
784 a local network to syncronize the audio output of all
785 clients that play the same stream.
787 ------------------------------------------
788 0.2.2 (2005-08-19) "tangential excitation"
789 ------------------------------------------
791 Mostly internal changes in this release, but also some new commands
792 for the mysql database tool.
794 - cleanup exec.c, fix para_exec bug
795 - compile time loglevel (log messages below the given level
796 won't be compiled in, which reduces the size of the
798 - new log macros that shorten the size of the source code.
799 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
800 to send only zeros. With this workaround, para_audioc works
802 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
803 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
804 (new entry), "snp" (set numplayed). Read the manual for more
807 ---------------------------------------
808 0.2.1 (2005-08-15) "surreal experience"
809 ---------------------------------------
811 Here comes paraslash-0.2.1. It contains a couple of new features and,
812 surprise, only minor bug fixes.
814 - kill noisy mp3 debug message
815 - cleanup of the build system
816 - para_server and para_client directly use the crypto routines
817 of the openssl library rather than invoking the openssl command
819 - server/audiod: new option --user to switch to the given user
820 when invoked as root. Read the output of "para_server -h" for
822 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
823 status. Default: "para_audioc stat"
824 - sdl_gui: new option --pic_cmd to be used to download the picture.
825 Default: "para_client pic"
826 - audiod: 5 slots ought to be enough for everybody
827 - audiod: new status item: Uptime, kill hup command
829 ------------------------------------------
830 0.2.0 (2005-08-06) "distributed diffusion"
831 ------------------------------------------
833 After several month of increased development activity, paraslash-0.2.0
834 has arrived. It contains many new features and is much more
835 self-contained than the old 0.1.x series. Enjoy!
838 - para_server: fix hang on song change and crash on sighup.
839 Speed up mysql queries. The DIR_LIKE macro is gone.
840 - new executables: para_audiod, the local audio daemon that
841 starts playback (uses SCM_CREDENTIALS socket magic) and
842 para_audioc, the corresponding client.
843 - new executables: para_mp3dec/para_oggdec, two really teensy
844 decoders. para_mp3dec is based on libmad, para_oggdec requires
846 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
847 they are now called para_send and para_recv respectively.
848 - documentation updates
849 - para_gui is themable. For now there is the default theme that
850 looks as before and the simple theme: blue and easy.
851 - gui: audio streaming is now handled by audiod. Time display shows
852 playback time rather than streaming time
853 - slider: update to libzmw-0.2.0
854 - para_krell: fix crash on server shutdown
855 - switch from gzip to bzip2
857 ----------------------------------------
858 0.1.7 (2005-04-18) "melting penetration"
859 ----------------------------------------
861 The main change in this release is clearly the oggvorbis rewrite,
862 but there are also lots of smaller changes. If you intend to use both
863 the mp3 and the ogg plugin, it is recommended to use software mixing,
864 e.g. the dmix plugin which is provided by ALSA.
866 - new executables: para_ovsend and para_ovrecv for sending/receiving
867 oggvorbis files via rtp. Requires the open rtp library. Get it at
868 http://www.linphone.org/ortp/
869 - rewrite of the ogg_vorbis core code
870 - configure detects libzmw and, if detected, includes
871 para_slider to the list of binaries to be built by make
872 - server stream writers read from their associated fifo rather
874 - slider: two new sliders, lastplayed and numplayed
875 - fix nasty double free bug which caused random segfaults in case of
876 mp3 files with invalid header information
877 - gui: new command line option: --stream_timeout=seconds to
878 deactivate a slot if it is idle for that many seconds (default=`5')
881 ---------------------------------------
882 0.1.6 (2005-03-05) "asymptotic balance"
883 ---------------------------------------
885 Only little user-visible changes in this release. Mainly bugfixes and
886 core code cleanup. This is probably the most stable version ever if you
889 - fix several memory leaks
890 - rename default name of mysql database from "music" to "paraslash".
891 Use para_server's --mysql_database option if you do not want to
892 rename your old database.
893 - rework ogg vorbis code
894 - make update command work on mysql servers with LOCAL_INFILE
896 - gui: improved stream I/O (slots)
897 - simplified audio format API
898 - para_pob_ogg is gone
900 ------------------------------------
901 0.1.5 (2004-12-31) "opaque eternity"
902 ------------------------------------
904 Let's slide gently into the new year.
906 - new: para_slider (not built automatically, type "make
907 para_slider" to build). A toy for those who always felt that
908 creating stream definitions is difficult. See screenshots,
909 README and FEATURES for more info.
910 - improved signal handling. Fixes server segfault on SIGHUP
911 for linux kernels newer than Aug 24 2004 and makes para_gui
913 - reload database tool on SIGHUP
914 - improved help message for sl
915 - do not log "broken pipe" messages as errors. They are
917 - fix wrong error message on permission errors
919 -----------------------------------------
920 0.1.4 (2004-12-19) "tunneling transition"
921 -----------------------------------------
923 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
924 Hopefully, most of them got wiped out with this release. Some
925 enhancements went also in.
927 - improved error diagnostics for all commands
928 - stradd/picadd: overwrite previous contents if entry already
929 exists, rather than returning errors
930 - stradd: use current stream if invoked without args
931 - faster (and hopefully more stable) ogg-vorbis handling
932 - para_krell: reap children to avoid zombie-flooding in case
934 - si: report also server pid
935 - server: don't busy-loop if dbtool reports only invalid files.
936 - gui: CTRL+C works again, fix stream_read command line option
938 - fix mysql dbtool startup in case no database exists
939 - many small fixes and cleanups
941 ---------------------------------------
942 0.1.3: (2004-12-10) "vanishing inertia"
943 ---------------------------------------
945 Starting from this release, the database tools are integrated in the
946 server binary. This decreases server startup time, reduces code size
947 and speeds up database commands. However, the layout of the underlying
948 mysql database changed only slightly and 0.1.3 should be backwards
949 compatible in that respect.
953 - If mysql is not detected at compile time, or fails to init
954 at runtime, fall back to the dopey database tool which should
956 - para_dbtool and dbtool.conf are gone. All mysql specific
957 options are read from server.conf and are prefixed by 'mysql_'.
958 - new command: cdt (change database tool)
959 - new command line option: dbtool (choose startup database tool)
960 - The name of current stream is now stored in the database,
961 so paraslash remembers its current stream when restarted.
962 - new command: csp (change stream and play)
963 - para_gui also reports current database tool and server uptime
965 -------------------------------------------
966 0.1.2: (2004-11-28) "spherical fluctuation"
967 -------------------------------------------
969 Point release before the big dbtool changes go in.
971 - dbtool: rename ca to cam (copy all meta data). It now also
972 copies numplayed and lastplayed time as well as the picture
974 - fix endless-loop-bug caused by mp3 files with invalid header
976 -----------------------------------------
977 0.1.1: (2004-11-05) "floating atmosphere"
978 -----------------------------------------
981 - new dbtool command: mbox. Browse your sound-file collection
982 with your favorite mail reader.
983 - several small fixes
985 -------------------------------------
986 0.1.0: (2004-10-22) "rotating cortex"
987 -------------------------------------
989 - fix logging bug for loglevel > VERBOSE
991 - correct timings for vbr mp3s
992 - modular audio format support
993 - ogg-vorbis support (experimental)
994 - new server option: autoplay
996 -----------------------------------------
997 0.0.99: (2004-07-25) "harmonic deviation"
998 -----------------------------------------
1000 - rename projectname from icc to paraslash (play, archive, rate
1001 and stream large audio sets happily)
1002 - paraslash is no longer restricted to one particular audio
1004 - new dbtool commands (stradd, strq, strdel) for easy stream
1005 managment w/o configuration file. That obsoletes stream_defs
1006 file/config option for dbtool.
1007 - picadd accepts jpeg data from stdin
1008 - new server commands: ps (select previous stream), sc (song change)
1009 - new default pictures for sdl_gui
1010 - gui: new key_map option for binding commands and internal
1011 functions to arbitrary keys, nice help screen, rip out
1012 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1013 show silly logo on startup
1014 - new executables: para_fade for fading volume, para_dbadm for
1015 manipulating attributes
1016 - cdb adds _all_ tables to mysql database
1017 - revised and beautified documentation
1018 - sample dbtool rewritten in C
1021 ---------------------------------------------
1022 0.0.98: (2003-12-26) "incremental smoothness"
1023 ---------------------------------------------
1025 - kick icecast in favour of poc. That removes some races and reduces
1026 core code considerably.
1027 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1028 give finer info on afs' status.
1029 - gui can start decoder (see config options). Further new gui
1030 commands: refresh (^L), jmp (F1-F10)
1031 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1032 terminates gui. This fixes dead instances consuming memory
1034 - new dbtool command: verb for sending verbatim sql queries.
1035 - fix pid_list races (by removing pid_list)
1038 --------------------
1039 0.0.97: (2003-10-26)
1040 --------------------
1042 - installation prefix now defaults to /usr/local
1043 - new commands for gui: snozze, sleep and reread config
1044 - config file for gui and sdl_gui
1045 - fix problems with filenames containing funny characters
1046 (reported by Thomas Forell)
1047 - improved signal handling for gui, now it rereads conf on SIGHUP
1048 - new dbtool command: cdb (create database)
1049 - switch from argtable to gengetopt
1050 - major code cleanup and speed improvements
1051 - fix several potential buffer overflows
1052 - many small fixes and cleanups
1058 - easy stream_defs syntax
1059 - sdl_gui can display images associated to the file being played
1060 - Major feature enhancements for icc_gui including dynamic text
1061 placement and the top/bottom window design
1062 - vrfy/clean now also checks for NULL values in attributes as
1063 well as for invalid picture pointers
1064 - fix long outstanding case sensitivity bug
1065 - many small fixes and cleanups
1071 - sdl gui runs much faster
1072 - new dbtool command: ca (copy attributes)
1073 - count and display number of times the song has been played
1074 - new feature: scoring
1075 - command line options for sdl_gui
1076 - simpler syntax of streams file
1077 - decrease network traffic of stat
1079 - many small fixes and cleanups
1085 - new server command: ns (next stream)
1086 - new icc_gui command: c (change stream)
1088 - stat shows also id3 tag info
1090 - log flodding bug fixed
1091 - many small fixes and cleanups
1097 - colors for icc_gui
1098 - icc_gui sets volume directly (linux only)
1099 - proper locking that fixes some races
1100 - fix security bug that caused commands to be executed even
1101 with unsufficient permissions
1102 - new command: hup to make all servers reread their configuration file
1103 - icecast meta data streaming
1104 - many small fixes and cleanups
