Merge branch 't/mmap_sanity'
[paraslash.git] / NEWS
1 -----------------------------------------------
2 0.4.10 (to be announced) "heterogeneous vacuum"
3 -----------------------------------------------
4
5 - The --no_default_filters option of para_filter has been
6 depricated. It still works but has no effect and will be
7 removed in the next version.
8 - Cleanup and consolidation of the various wrappers for
9 write(), writev(), send() and friends.
10 - The obscure error messages on mmap() failures have been
11 replaced by meaningful messages. This affects mainly
12 para_afh.
13
14 -------------------------------------
15 0.4.9 (2011-12-06) "hybrid causality"
16 -------------------------------------
17
18 Support for another audio format, interactive mode for para_client
19 and para_audiod and many small improvements/fixes all over the place.
20
21 - Support for flac, the free lossless audio codec.
22 - Fix for an endless loop in the mp3 decoder for certain
23 (corrupt) mp3 files.
24 - When executed without specifying a command, para_client
25 and para_audioc start an interactive shell (requires
26 libreadline being installed). The interactive mode offers
27 full tab completion and command line history.
28 - autogen.sh now detects a distcc setup and adjusts the
29 parameter for the -j option of make accordingly.
30 - Shared memory areas are no longer restricted to 64K. We now
31 detect the maximal size of a shared memory area at runtime.
32 - cleanup of the internal uptime API.
33 - para_server prefaults the mmapped audio file to avoid
34 delays on slow media.
35 - A new test for the test-suite that exercises the
36 communication between para_server and para_audiod.
37 - The alsa writer eats up less CPU cycles when configured to
38 use the DMIX plugin.
39 - Simplified and unified receiver code.
40 - Makefile cleanups.
41 - Commands which print a list of matching audio files now
42 emit a meaningful error message if no audio file matched the
43 given pattern(s).
44
45 --------------------------------------
46 0.4.8 (2011-08-19) "nested assignment"
47 --------------------------------------
48
49 Gcrypt support, the overhauled osx writer and regex format specifiers
50 are the highlights of this release.
51
52 - support for libgcrypt as a drop-in replacement for openssl.
53 Run configure --enable-cryptolib=gcrypt to link against
54 libgcrypt. The two crypto implementations are compatible to
55 each other, i.e. a para_client executable linked against
56 gcrypt can connect to para_server linked against libssl
57 and vice versa.
58 - Rewrite of the osx writer (output plugin for Mac OS).
59 - audiod: The format specifier for receivers, filters and
60 writers is now treated as a regular expression. This allows
61 to replace 5 lines in the config file (one for each audio
62 format) by one single line. See the manual for details.
63 - The *.cmdline.[ch] files are no longer contained in the released
64 tarballs. This reduces the size of the tarballs but requires
65 gengetopt to build the tarball.
66 - Compiles cleanly also with llvm/clang.
67 - Corrupt mp3 files are handled more gracefully.
68 - The alsa writer uses poll fds instead of computing timeouts.
69 - Cleanup of the generic writer API.
70 - sched: Optimized zero timeouts.
71 - vss timeout cleanups.
72 - oggdec fixes and improvements.
73
74 --------------------------------------
75 0.4.7 (2011-06-01) "infinite rollback"
76 --------------------------------------
77
78 The new ao writer, support for ssh RSA keys and a couple of other
79 enhancements.
80
81 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
82 platforms through the libao audio library.
83 - Support for RSA keys generated with ssh-keygen.
84 - configure: improved options for ogg/vorbis/speex.
85 - The git version reported by --version always matches HEAD.
86 - The autogen script detects the number of processors and
87 runs a parallel make if possible.
88 - Major cleanup of the crypto API.
89 - Documentation updates.
90
91 ------------------------------------------
92 0.4.6 (2011-03-31) "deterministic entropy"
93 ------------------------------------------
94
95 Lots of ogg/vorbis improvements, the new test suite, enhancements
96 for para_gui and a fair amount of other bug fixes.
97
98 - For DCCP/OGG streams the audio file header is only sent once
99 at the beginning of the stream rather than periodically
100 every five seconds. This reduces network traffic and the
101 FEC group size.
102 - The vorbis comment header is replaced by an empty dummy header
103 before the header is sent over the network. This also results in
104 less network traffic and smaller FEC groups.
105 - The new "test" make target allows to perform some sanity checks prior
106 to installing the package.
107 - ogg timing fixes and performance improvements
108 - Scheduler improvements
109 - Proper exit codes for para_write
110 - para_gui: New option --theme to select a startup theme. Several
111 other improvements and fixes.
112 - aacdec error message cleanups
113 - simplified color error handling
114
115 --------------------------------------------
116 0.4.5 (2010-12-17) "symmetric randomization"
117 --------------------------------------------
118
119 Bug fixes, internal cleanups and variable-sized FEC slices.
120
121 - Contains a fix for an invalid-free-bug in the ogg audio format
122 handler code.
123 - Switching off the DCCP sender works again.
124 - para_audiod handles crashes of para_server more robustly.
125 - Internal scheduler and writer cleanups.
126 - Reduced latency due to variable-sized FEC slices.
127 - Improved documentation and error diagnostics.
128 - The build of para_server is now optional, allowing the build
129 to succeed in case libosl is not installed.
130
131 ------------------------------------------
132 0.4.4 (2010-08-06) "persistent regularity"
133 ------------------------------------------
134
135 Support for yet another audio format, para_write improvements and
136 bug fixes.
137
138 - Support for the speex codec.
139 - Support for sample formats other than 16 bit little endian.
140 - error2.h is now created by a perl script which speeds up configure
141 considerably.
142 - Fix a bug in the aac decoder which could lead to segfaults in
143 para_filter/para_audiod.
144 - Fixes for autoconf-2.66.
145
146 ----------------------------------------
147 0.4.3 (2010-07-05) "imaginary radiation"
148 ----------------------------------------
149
150 Many improvements for the DCCP and the UDP transport, the new user
151 manual and the usual mix of bug fixes and internal improvements.
152
153 - FEC support for the DCCP sender (Gerrit Renker). The new
154 --dccp_max_slice_size, --dccp_data_slices_per_group and
155 --dccp_slices_per_group options can be used to set the FEC
156 parameters for the DCCP transport.
157 - DNS lookups for UDP targets (Gerrit Renker).
158 - The new user manual replaces the README, README.afs, REQUIREMENTS
159 and INSTALL documents.
160 - Fix an end-of-file detection bug in the oggdec filter.
161 - The new nonblock API.
162 - Both options of the oggdec filter have been removed.
163 - New debug mode for the internal scheduler.
164
165 ------------------------------------------
166 0.4.2 (2010-04-23) "associative expansion"
167 ------------------------------------------
168
169 It's been some time since the last release, but finally here is
170 paraslash-0.4.2. The bulk of the changes comes from the new buffer
171 tree API, but there are changes all over the tree. Mainly performance
172 and usability improvements, but also quite some bug fixes.
173
174 - The new buffer tree API.
175 - DCCP: Support for CCID negotiation (Gerrit Renker).
176 - UDP robustness fixes.
177 - The --bufsize option for mp3dec is gone as it no longer makes sense
178 for the new buffer tree API.
179 - Fix audible buffer underruns for wma streams.
180 - The alsa writer no longer prints meaningless underrun durations.
181 - audiod: Defaults work also for udp streams. If no filter is
182 given for an audio format that is received via upd, fecdec is
183 automatically added as the first filter (along with the decoder).
184
185 ---------------------------------------
186 0.4.1 (2009-12-22) "concurrent horizon"
187 ---------------------------------------
188
189 Support for another audio format, minor feature enhancements and lots of bug
190 fixes. All fixes that have been accumulated in the maint branch (in particular
191 those mentionened in the 0.3.6 release notes) appear in this release as well.
192
193 - wma support.
194 - new afh option: --human to activate human-readable output.
195 - new server/audiod option: --log-timing to print timing information.
196 - build system improvements.
197 - source code documentation updates.
198
199 -------------------------------------
200 0.3.6 (2009-12-07) "cubic continuity"
201 -------------------------------------
202
203 Quite a few bugs have been found and fixed since 0.3.5, so here's
204 another 0.3.x release. No new features.
205
206 - Always check return value of malloc().
207 - ogg vorbis/FEC: Do not write garbage after the audio file header.
208 - exit if root privileges could not be dropped.
209 - FEC: Fix computation of extra slices.
210 - oss: Fix check for empty input buffer.
211 - Avoid buffer underruns due to filter chain output buffer constraints.
212 - server: Fix assignment of afs_pid.
213 - Don't panic if the afs database contains unknown audio formats.
214 - http/dccp: Do not send the audio file header twice.
215 - FEC: Timing improvements.
216
217 ----------------------------------------------
218 0.4.0 (2009-11-10) "simultaneous independence"
219 ----------------------------------------------
220
221 Two significant changes which require the new version number: The
222 improved authentication dialog and the fact that the database code
223 has been moved to a library, libosl. To use the new version, you have
224 to generate new RSA keys, see INSTALL for details. A shell script is
225 provided for conversion of the 0.3 database to the new 0.4 format.
226
227 - stronger crypto for client authentication
228 - the database code has been moved to a library
229 - improved status item handling
230 - cleanup of the build system
231 - The "-V" option now also prints the git version
232 - the new parser-friendly listing mode for the ls and stat commands
233 - mandatory rc4 encryption
234 - major audio format handler cleanups
235 - (id3,...) tags are no longer stored as a combined string in the database
236 - new mood methods: artist_matches, title_matches, comment_matches,
237 album_matches, year_maches, year.
238
239 --------------------------------------------
240 0.3.5 (2009-09-21) "symplectic separability"
241 --------------------------------------------
242
243 Full client support for *BSD Unixes, complete re-write of the ogg
244 vorbis audio format handler, various improvements all over the place
245 and the usual mix of bugfixes. This release marks the end of the 0.3
246 series if no serious problems show up.
247
248 - the new oss writer (supported on *BSD and Linux)
249 - rewrite of the ogg vorbis audio format handler. It's
250 recommended to replace the chunk tables of existing ogg
251 vorbis files in the afs database by re-adding these files
252 with "add -f".
253 - support for netmask subsets (Gerrit Renker)
254 - the new prebuffer filter
255 - improved signal handling
256 - variable fec output buffer size
257 - improved FEC timing fixes audible buffer underruns in UDP mode
258 - --log_color actually works
259 - new ls option: -d (print dates as seconds after the epoch)
260 - update to gengetopt 2.22.2
261 - support for RSA keys of size > 512 bits
262 - new option "mixer_channel" for para_fade
263
264 -----------------------------------------
265 0.3.4 (2009-05-07) "elliptic inheritance"
266 -----------------------------------------
267
268 The new udp sender, forward error correction, colored logs and various
269 other improvements. As the udp sender does not depend on any special
270 libraries, it is built unconditionally.
271
272 - The udp sender replaces the ortp sender. The new code uses forward
273 error correction to protect against packet losses. Many thanks to
274 Gerrit Renker for providing ipv6 support.
275 - The default port for udp streaming now defaults to 8000, like
276 for the http and the dccp senders/receivers.
277 - Loglevels are now specified as symbolic names, e.g.
278 "--loglevel info".
279 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
280 - para_server/para_audiod: Color support for log messages.
281 - new options for mp3dec: --ignore-crc, --bufsize
282 - new audiod option: --config-file.
283 - gengetopt cleanups.
284 - Improved help/man pages: The documentation of para_audiod,
285 para_recv, para_filter and para_write now also contains
286 all options of the available receivers/filters/writers. The
287 man page of para_fade contains a description of the different
288 modes of operation.
289 - More source code documentation.
290 - vss timing fixes.
291
292 --------------------------------------------
293 0.3.3 (2008-12-01) "axiomatic perspectivity"
294 --------------------------------------------
295
296 Internal code cleanups, bug fixes, improved tag handling and the new
297 amplification filter.
298
299 - para_server uses the generic scheduling code.
300 - overhaul of the virtual streaming system.
301 - mp3: id3 version 2 support via libid3tag (optional)
302 - ogg: vorbis comment support.
303 - aac meta info support.
304 - mp3 audio format handler cleanups.
305 - new filter: "amp" to amplify the amplitude of the audio stream
306 - new status item/database entry: amplification. It is
307 used by the amp filter to pre-amplify the audio stream.
308 - fix a close-without-open bug in para_write.
309 - fix a bug in com_init() which was introduced in 0.3.2.
310 - better error diagnostics for para_client.
311
312 -----------------------------------------
313 0.3.2 (2008-04-11) "probabilistic parity"
314 -----------------------------------------
315
316 The new para_afh executable, scheduling and documentation improvements.
317
318 - new ls option: -lc (list chunk table)
319 - new executable: para_afh, the stand-alone audio file handler tool
320 - afs commands can send output more than SHMMAX (32MB on Linux). This
321 also reduces the memory usage of commands that produce large amounts
322 of output.
323 - major scheduler and audiod cleanups.
324 - more detailed and much nicer man pages.
325
326 ---------------------------------------
327 0.3.1 (2008-02-23) "liquid interaction"
328 ---------------------------------------
329
330 A mix of cleanups, bug fixes, improvements, and some new features. No
331 significant changes to the new database (osl) code, which is generally
332 a good sign.
333
334 - Share some similar/duplicate code between the http and the
335 dccp sender.
336 - Generic access control lists for paraslash senders.
337 - dccp sender: Access control lists, connection limiting and support
338 for the allow,deny,on,off,help sender commands.
339 - The default dccp port changed from 5001 to 8000 (suggested by
340 Gerrit Renker).
341 - para_server starts even if not all public keys could be loaded.
342 - Audiod performance improvements.
343 - fix a bug in the "off" command of the http sender.
344 - fix some fd and memory leaks.
345 - Update to gengetopt-2.22.
346
347 -------------------------------------
348 0.3.0 (2008-01-12) "solar saturation"
349 -------------------------------------
350
351 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
352
353
354 Usually one might expect lots of new features AND a big increase in size
355 for a major release like this.
356
357 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
358 ever. The decrease in size is mostly due to the removal of some
359 graphical tools (which were only quick hacks anyway). But also the
360 fact that the mysql code is gone cuts down the size a bit.
361
362 Being independent of mysql comes at a cost: The fact that paraslash
363 now contains its own database (the object storage layer, osl) increases
364 the (stripped) binary size of para_server by ~50K on i386.
365
366 - no more restrictions on unique basenames.
367 - independent of mysql: The new self-contained object
368 storage layer (osl) replaces the mysql database.
369 - New executable para_fsck: Check integrity of osl tables.
370 - Lyrics support.
371 - Reliable audio file move/rename detection.
372 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
373 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
374 Solaris (sparc64).
375 - the new osl-based audio file selector (afs) replaces the random,
376 the playlist and the mysql selector of paraslash-0.2.x.
377 - IPv6 support (thanks to Gerrit Renker).
378 - paraslash-0.2.x streams are now called "moods". Writing
379 0.3.x-mood definitions should be both easier and more
380 powerful than writing 0.2.x-stream definitions.
381 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
382 been removed. The world is a better place without them. However,
383 para_gui is still there.
384 - afs tracks audio file selection also in playlist mode.
385 - few easy-to-use afs commands replace the many not-so-easy-to-use
386 mysql commands (and are available also in playlist mode).
387 - Improved error subsystem.
388 - The earth-shaking new logo.
389
390 -----------------------------------------
391 0.2.17 (2007-11-20) "isotropic threshold"
392 -----------------------------------------
393
394 Mainly bugfixes and cleanups in this version which marks the end of
395 the 0.2.x series if no serious bugs show up after the release.
396
397 - mysql_selector: fix a locking bug.
398 - universal chunk queueing.
399 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
400 to Gerrit Renker).
401 - be more carful wrt. signed vs. unsigned argument passing.
402 - cleanup error.h and fix some references to invalid error
403 codes.
404 - update to gengetopt-2.21.
405 - update to ortp-0.13.1.
406 - autoconf: extend checks for headers, library functions and
407 compiler characteristics.
408 - Fix streaming of large mp3 files.
409 - Fix an off-by-one bug in playlist handling.
410
411 --------------------------------------
412 0.2.16 (2007-04-05) "neural discharge"
413 --------------------------------------
414
415 The main change in this release is the major audio format handler
416 cleanup which removes some similar/duplicate code and makes it easier
417 to implement plugins for other audio formats. Of course, the usual mix
418 of other improvements/changes/bugfixes also made it into the release.
419
420 - simplified audio format handlers (most of the handling functions
421 were moved one layer up to the virtual streaming system).
422 - para_server uses mmap to read audio files
423 - repositioning of mp3 streams is much faster, in particular for
424 jumping near the end of large mp3 files.
425 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
426 and AFS_WRITE.
427 - fix a bug in para_filter that caused decoding of aac files
428 to start only after a few seconds.
429 - fix osx_writer hangs
430 - simplified dccp code (thanks to Gerrit Renker)
431 - the compress filter works also on big endian systems (ppc)
432
433 -----------------------------------------
434 0.2.15 (2007-02-16) "inductive resonance"
435 -----------------------------------------
436
437 Minor improvements, more documentation and a bunch of bug fixes.
438
439 - para_server: The server.users file is only read once on server
440 startup rather than for each connection
441 - mp3dec: Fix decoding of corrupt mp3 files
442 - afs (audio file sender) is now called vss (virtual streaming
443 system). Consequently, the permission flags specified in
444 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
445 become VSS_READ and VSS_WRITE respectively.
446 - para_audiod/para_filter: Fix a bug that caused the last chunk
447 of audio data not being written under certain circumstances
448 - audiod: compute the difference of server time and local time
449 correctly
450 - para_server/para_audiod: Fix some memory leaks
451 - documentation improvements
452 - configure.ac: fix checks for para_krell
453 - new man pages
454
455 -------------------------------------------
456 0.2.14 (2006-10-15) "transient singularity"
457 -------------------------------------------
458
459 The only major enhancement of this version is the osx writer which completes
460 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
461 until now for reasons beyond the scope of this changelog entry.
462
463 - new output plugin for Mac Os: the osx writer
464 - rename configure command line options from --enable-xxx-headers to
465 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
466 - configure: new command line options: --with-mad-headers,
467 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
468 - some robustness fixes
469 - dymamic audio format recognition for audiod
470 - para_server: new command line option: --autoplay_delay
471 - para_audiod: new command line option: --clock_diff_count
472
473 ---------------------------------------
474 0.2.13 (2006-07-14) "sonic convolution"
475 ---------------------------------------
476
477 A bunch of new features and core changes.
478
479 - the new paraslash scheduler, short and sweet.
480 - Support for m4a/mp4 files via the new aac audio format
481 handler/filter (requires libfaad).
482 - each writer has its own command line parser, just like
483 para_recv and para_filter.
484 - para_client and para_audioc use the error subsystem
485 - writers are integrated in para_audiod (currently linux-only)
486 - para_client is integrated in para_audiod
487 - random/playlist selector: improved info strings
488 - new audiod commands: tasks, kill
489 - update to libortp-0.10.1
490 - para_fade: wake time defaults to 8 hours from now
491 - update to autoconf-2.60
492
493
494 ------------------------------------------
495 0.2.12 (2006-05-12) "oriented abstraction"
496 ------------------------------------------
497
498 Many user-visible changes in this release and lots of new
499 features:
500
501
502 - the new optional dccp sender/receiver. It uses the datagram
503 congestion control protocol. You'll need a fairly new kernel
504 for this.
505 - paraslash works on Mac OS X (thanks to Gerd Becker)
506 - para_play renamed to para_write
507 - modular output plugin design (writers) for para_write
508 - new file_writer output plugin for para_write
509 - compress filter speed improvements
510 - update to libortp-0.9.1
511 - update to gengetopt-2.17rc
512 - para_client no longer depends on libreadline (as the
513 code for the interactive mode was removed).
514 - gcc-2-95 is no longer a supported compiler. It may still
515 work, but it gets no more testing.
516 - the tarball no longer contains the screenshot images which
517 reduces its size quite a bit.
518 - configure: new command line options: --enable-mysql-headers
519 and --enable-mysql-libs
520
521 ------------------------------------
522 0.2.11 (2006-03-11) "atomic duality"
523 ------------------------------------
524
525 Here it is, the first paraslash release developed with git. There
526 are fairly many user-visible changes in this release. As two out of
527 the three "database tools" of paraslash don't use a database at all,
528 they are now called "audio file selectors" instead.
529
530
531 - the cdt command (change database tool) becomes chs (change
532 selector)
533 - no more colon separators: The syntax of some options of
534 para_audiod and para_filter have changed. Use --help for
535 more info (and some examples).
536 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
537 - switch from cvs to git (should've done that earlier)
538 - the new ipc subsystem
539 - new audio file selector: playlist
540 - para_server: the dopey selector is now called "random",
541 and is the default selector. Use the --selector option to
542 choose another selector at startup, or the chs command to
543 change the selector at runtime.
544 - X86_64 fixes (thanks to Steffen Klassert)
545 - para_play fixes
546
547
548 --------------------------------------
549 0.2.10 (2006-02-17) "cyclic attractor"
550 --------------------------------------
551
552 Huge documentation update, a scrollable window for para_gui, ortp
553 improvements, and of course many small fixes not mentioned here.
554 The diffstat below is rather misleading as most insertions are due
555 to the new source documentation.
556
557 - autoconf cleanup
558 - para_server also uses the new error subsystem
559 - lots of new documentation (UTSL)
560 - gui improvements:
561 - keysyms for cursor keys and for next/previous page keys
562 - scrollable output window
563 - new internal commands: scroll up/down, page up/down
564 - fix color of command output.
565 - ortp: the --chunk_time and --header flags are no longer needed
566 for para_recv/para_audiod as this information is now encoded in
567 each rtp packet sent by para_server.
568
569
570 -------------------------------------------
571 0.2.9 (2006-01-24) "progressive turbulence"
572 -------------------------------------------
573
574 Internal audiod receivers/filters, the new error subsystem and
575 a lot of small improvements.
576
577 - para_recv and para_filter are integrated into the para_audiod
578 binary, i.e. audiod no longer spawns a new process for
579 each receiver/filter. As para_recv and para_filter might be
580 useful as standalone programs, they still get built (linked
581 against the same object files that are also used for audiod).
582 - further ortp timing improvements should reduce the CPU usage
583 of the ortp receiver.
584 - improved audio grabbing. The 'grab' command of para_audiod
585 has its own set of command line options. Read the output of
586 "para_audioc help grab" for more info.
587 - oggdec: configurable input prebuffer size.
588 - the new error subsystem gives better error diagnostics
589 and reduces code size.
590
591
592 -----------------------------------------
593 0.2.8 (2006-01-02) "dynamic accumulation"
594 -----------------------------------------
595
596 The new modular filter design and the para_play-hangs bugfix.
597
598 - new executable: para_filter. It combines para_mp3dec,
599 para_oggdec and para_compress. It also adds a further filter
600 type, wav, that just inserts a wave header at the desired point
601 of the filter chain. All 'piping' is done in-memory (i.e. no
602 read/write operations are used).
603 - para_play: fix a stupid bug that caused it to hang under
604 certain circumstances.
605
606
607 -------------------------------------------
608 0.2.7 (2006-12-27) "transparent invariance"
609 -------------------------------------------
610
611 Not many user-visible changes but a fair amount of internal improvements.
612
613
614 - The http sender buffers data if it can not be sent
615 out immediately (because the socket is not writable). This
616 should prevent para_server from shutting down the connection
617 too early on a loaded network.
618 - para_play also prebuffers data if it is told to start at a
619 future time by the --start_time option.
620 - The return of para_recv: It combines para_ortp_recv and
621 para_http_recv. Use the --receiver option to switch between
622 the two. para_recv builds without libortp, but contains
623 only the http receiver in this case.
624 - update to ortp 0.8.1. As this ortp release contains incompatible
625 changes, para_recv-0.2.7 won't link against older ortp libs.
626 - improved ortp timings.
627 - use of gcc-extensions that #define away for non-gcc and
628 gcc < 3.0.
629
630
631 -------------------------------------------
632 0.2.6 (2005-10-29) "recursive compensation"
633 -------------------------------------------
634
635 Transparent session encryption (uses openssl's Alleged RC4 cipher),
636 the internal find command and several other improvements and cleanups.
637
638 - Encrypt the session if encryption is requested by the client
639 (default for para_client 0.2.6). This is backwards
640 compatible, so older clients can still connect to para_server
641 0.2.6. Use the new client option --plain to request an
642 uncrypted session (off by default, must be set to on in
643 order to connect to para_server 0.2.x with 0 <= x <= 5).
644 - para_server uses an internal function to locate audio files
645 rather than calling find(1). The server option
646 --mysql_audio_file_dir replaces --mysql_find_cmd.
647 - documentation update
648 - man pages
649 - header file cleanup
650 - para_client code cleanup
651 - para_gui: faster display of output of display commands
652
653
654 ------------------------------------------
655 0.2.5 (2005-10-13) "aggressive resolution"
656 ------------------------------------------
657
658 This release adds internal senders, i.e. no more external programs are
659 spawned for sending out the audio data. There are two different senders
660 available: The http sender and the ortp sender (former para_send which
661 is no longer needed).
662
663 The new sender code has a plugin-like design so it can be easily
664 extended should there be be any future need for supporting another
665 network streaming protocol. All senders are completely independent of
666 each other. In particular, the http and the ortp sender can operate
667 in parallel.
668
669 - new server command: sender to control senders at runtime.
670 Read the output of "para_server -h" and "para_client help
671 sender" for more information.
672 - para_recv renamed to para_ortp_recv
673 - new executable: para_http_recv, a simple command line
674 http receiver.
675 - major afs/mp3/ogg code simplifications due to internal
676 senders.
677 - ogg timing improvements
678 - fix several minor memory leaks (found by valgrind)
679 - empty stream definitions work again
680 - com_ne(): ignore errors on remove
681 - audiod: fix segfault on server restart
682
683
684 ---------------------------------------
685 0.2.4 (2005-09-21) "toxic anticipation"
686 ---------------------------------------
687
688 Several small improvements, fixes and the new grab command.
689
690 - audiod:
691 - new command: "grab" to grab the output of the stream reader
692 or any filters. Read the output of "para_audioc help grab"
693 for more information.
694 - fix memory leak
695 - code cleanup
696 - audioc: new command line option: --bufsize to specify a
697 buffer size different from the default size 8192.
698 - improved error diagnostics for para_play.
699 - new configure option: --enable-ssldir so search for openssl in
700 non-standard places
701 - sdl_gui: Make it look nice again for 1024x768
702 - server: report total size of memory allocated with sbrk by malloc,
703 new command line option: --announce_time
704
705
706 -----------------------------------------
707 0.2.3 (2005-09-01) "hydrophilic movement"
708 -----------------------------------------
709
710 Two new executables and major feature enhancements.
711
712 - audiod filters: It is now possible to specify arbitrary many
713 (including none) filters for each supported audio
714 format. This can be used e.g. for normalizing volume,
715 transforming or grabbing the audio stream, or for using
716 visualizers. Read the output of "para_audiod -h" for the
717 syntax of the new --filter_cmd option.
718 - new executable: para_play, a tiny alsa player. It
719 can play wave files or raw pcm (16 bit little endian)
720 from stdin.
721 - new executable: para_compress, a dynamic range compressor
722 intended to keep audio output at a consistent volume. Derived
723 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
724 - audiod: New option: --stream_delay. This can be used in
725 a local network to syncronize the audio output of all
726 clients that play the same stream.
727
728
729 ------------------------------------------
730 0.2.2 (2005-08-19) "tangential excitation"
731 ------------------------------------------
732
733 Mostly internal changes in this release, but also some new commands
734 for the mysql database tool.
735
736 - cleanup exec.c, fix para_exec bug
737 - compile time loglevel (log messages below the given level
738 won't be compiled in, which reduces the size of the
739 resulting binaries)
740 - new log macros that shorten the size of the source code.
741 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
742 to send only zeros. With this workaround, para_audioc works
743 again.
744 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
745 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
746 (new entry), "snp" (set numplayed). Read the manual for more
747 information.
748
749
750 ---------------------------------------
751 0.2.1 (2005-08-15) "surreal experience"
752 ---------------------------------------
753
754 Here comes paraslash-0.2.1. It contains a couple of new features and,
755 surprise, only minor bug fixes.
756
757 - kill noisy mp3 debug message
758 - cleanup of the build system
759 - para_server and para_client directly use the crypto routines
760 of the openssl library rather than invoking the openssl command
761 line utitlity
762 - server/audiod: new option --user to switch to the given user
763 when invoked as root. Read the output of "para_server -h" for
764 more information.
765 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
766 status. Default: "para_audioc stat"
767 - sdl_gui: new option --pic_cmd to be used to download the picture.
768 Default: "para_client pic"
769 - audiod: 5 slots ought to be enough for everybody
770 - audiod: new status item: Uptime, kill hup command
771
772
773
774 ------------------------------------------
775 0.2.0 (2005-08-06) "distributed diffusion"
776 ------------------------------------------
777
778 After several month of increased development activity, paraslash-0.2.0
779 has arrived. It contains many new features and is much more
780 self-contained than the old 0.1.x series. Enjoy!
781
782
783 - para_server: fix hang on song change and crash on sighup.
784 Speed up mysql queries. The DIR_LIKE macro is gone.
785 - new executables: para_audiod, the local audio daemon that
786 starts playback (uses SCM_CREDENTIALS socket magic) and
787 para_audioc, the corresponding client.
788 - new executables: para_mp3dec/para_oggdec, two really teensy
789 decoders. para_mp3dec is based on libmad, para_oggdec requires
790 libvorbisfile.
791 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
792 they are now called para_send and para_recv respectively.
793 - documentation updates
794 - para_gui is themable. For now there is the default theme that
795 looks as before and the simple theme: blue and easy.
796 - gui: audio streaming is now handled by audiod. Time display shows
797 playback time rather than streaming time
798 - slider: update to libzmw-0.2.0
799 - para_krell: fix crash on server shutdown
800 - switch from gzip to bzip2
801
802
803 ----------------------------------------
804 0.1.7 (2005-04-18) "melting penetration"
805 ----------------------------------------
806
807 The main change in this release is clearly the oggvorbis rewrite,
808 but there are also lots of smaller changes. If you intend to use both
809 the mp3 and the ogg plugin, it is recommended to use software mixing,
810 e.g. the dmix plugin which is provided by ALSA.
811
812 - new executables: para_ovsend and para_ovrecv for sending/receiving
813 oggvorbis files via rtp. Requires the open rtp library. Get it at
814 http://www.linphone.org/ortp/
815 - rewrite of the ogg_vorbis core code
816 - configure detects libzmw and, if detected, includes
817 para_slider to the list of binaries to be built by make
818 - server stream writers read from their associated fifo rather
819 than from stdin
820 - slider: two new sliders, lastplayed and numplayed
821 - fix nasty double free bug which caused random segfaults in case of
822 mp3 files with invalid header information
823 - gui: new command line option: --stream_timeout=seconds to
824 deactivate a slot if it is idle for that many seconds (default=`5')
825 - diffstats
826
827
828 ---------------------------------------
829 0.1.6 (2005-03-05) "asymptotic balance"
830 ---------------------------------------
831
832 Only little user-visible changes in this release. Mainly bugfixes and
833 core code cleanup. This is probably the most stable version ever if you
834 stick to mp3...
835
836 - fix several memory leaks
837 - rename default name of mysql database from "music" to "paraslash".
838 Use para_server's --mysql_database option if you do not want to
839 rename your old database.
840 - rework ogg vorbis code
841 - make update command work on mysql servers with LOCAL_INFILE
842 disabled
843 - gui: improved stream I/O (slots)
844 - simplified audio format API
845 - para_pob_ogg is gone
846
847 ------------------------------------
848 0.1.5 (2004-12-31) "opaque eternity"
849 ------------------------------------
850
851 Let's slide gently into the new year.
852
853 - new: para_slider (not built automatically, type "make
854 para_slider" to build). A toy for those who always felt that
855 creating stream definitions is difficult. See screenshots,
856 README and FEATURES for more info.
857 - improved signal handling. Fixes server segfault on SIGHUP
858 for linux kernels newer than Aug 24 2004 and makes para_gui
859 race-free.
860 - reload database tool on SIGHUP
861 - improved help message for sl
862 - do not log "broken pipe" messages as errors. They are
863 perfectly ok.
864 - fix wrong error message on permission errors
865
866 -----------------------------------------
867 0.1.4 (2004-12-19) "tunneling transition"
868 -----------------------------------------
869
870 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
871 Hopefully, most of them got wiped out with this release. Some
872 enhancements went also in.
873
874 - improved error diagnostics for all commands
875 - stradd/picadd: overwrite previous contents if entry already
876 exists, rather than returning errors
877 - stradd: use current stream if invoked without args
878 - faster (and hopefully more stable) ogg-vorbis handling
879 - para_krell: reap children to avoid zombie-flooding in case
880 no server is running
881 - si: report also server pid
882 - server: don't busy-loop if dbtool reports only invalid files.
883 - gui: CTRL+C works again, fix stream_read command line option
884 - fix pic_add, hist
885 - fix mysql dbtool startup in case no database exists
886 - many small fixes and cleanups
887
888 ---------------------------------------
889 0.1.3: (2004-12-10) "vanishing inertia"
890 ---------------------------------------
891
892 Starting from this release, the database tools are integrated in the
893 server binary. This decreases server startup time, reduces code size
894 and speeds up database commands. However, the layout of the underlying
895 mysql database changed only slightly and 0.1.3 should be backwards
896 compatible in that respect.
897
898 Visible changes:
899
900 - If mysql is not detected at compile time, or fails to init
901 at runtime, fall back to the dopey database tool which should
902 always work.
903 - para_dbtool and dbtool.conf are gone. All mysql specific
904 options are read from server.conf and are prefixed by 'mysql_'.
905 - new command: cdt (change database tool)
906 - new command line option: dbtool (choose startup database tool)
907 - The name of current stream is now stored in the database,
908 so paraslash remembers its current stream when restarted.
909 - new command: csp (change stream and play)
910 - para_gui also reports current database tool and server uptime
911
912
913 -------------------------------------------
914 0.1.2: (2004-11-28) "spherical fluctuation"
915 -------------------------------------------
916
917 Point release before the big dbtool changes go in.
918
919 - dbtool: rename ca to cam (copy all meta data). It now also
920 copies numplayed and lastplayed time as well as the picture
921 id.
922 - fix endless-loop-bug caused by mp3 files with invalid header
923
924 -----------------------------------------
925 0.1.1: (2004-11-05) "floating atmosphere"
926 -----------------------------------------
927
928 - gkrellm plugin
929 - new dbtool command: mbox. Browse your sound-file collection
930 with your favorite mail reader.
931 - several small fixes
932
933 -------------------------------------
934 0.1.0: (2204-10-22) "rotating cortex"
935 -------------------------------------
936
937 - fix logging bug for loglevel > VERBOSE
938 - fix skip command
939 - correct timings for vbr mp3s
940 - modular audio format support
941 - ogg-vorbis support (experimental)
942 - new server option: autoplay
943
944 -----------------------------------------
945 0.0.99: (2004-07-25) "harmonic deviation"
946 -----------------------------------------
947
948 - rename projectname from icc to paraslash (play, archive, rate
949 and stream large audio sets happily)
950 - paraslash is no longer restricted to one particular audio
951 streaming software
952 - new dbtool commands (stradd, strq, strdel) for easy stream
953 managment w/o configuration file. That obsoletes stream_defs
954 file/config option for dbtool.
955 - picadd accepts jpeg data from stdin
956 - new server commands: ps (select previous stream), sc (song change)
957 - new default pictures for sdl_gui
958 - gui: new key_map option for binding commands and internal
959 functions to arbitrary keys, nice help screen, rip out
960 soundcard/linux specific stuff, avoid noise artefacts while jumping,
961 show silly logo on startup
962 - new executables: para_fade for fading volume, para_dbadm for
963 manipulating attributes
964 - cdb adds _all_ tables to mysql database
965 - revised and beautified documentation
966 - sample dbtool rewritten in C
967 - autoconf
968
969 ---------------------------------------------
970 0.0.98: (2003-12-26) "incremental smoothness"
971 ---------------------------------------------
972
973 - kick icecast in favour of poc. That removes some races and reduces
974 core code considerably.
975 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
976 give finer info on afs' status.
977 - gui can start decoder (see config options). Further new gui
978 commands: refresh (^L), jmp (F1-F10)
979 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
980 terminates gui. This fixes dead instances consuming memory
981 continuously.
982 - new dbtool command: verb for sending verbatim sql queries.
983 - fix pid_list races (by removing pid_list)
984 - codename funnies
985
986 --------------------
987 0.0.97: (2003-10-26)
988 --------------------
989
990 - installation prefix now defaults to /usr/local
991 - new commands for gui: snozze, sleep and reread config
992 - config file for gui and sdl_gui
993 - fix problems with filenames containing funny characters
994 (reported by Thomas Forell)
995 - improved signal handling for gui, now it rereads conf on SIGHUP
996 - new dbtool command: cdb (create database)
997 - switch from argtable to gengetopt
998 - major code cleanup and speed improvements
999 - fix several potential buffer overflows

1021 - count and display number of times the song has been played
1022 - new feature: scoring
1023 - command line options for sdl_gui
1024 - simpler syntax of streams file
1025 - decrease network traffic of stat
1026 - fix zombie bug
1027 - many small fixes and cleanups
1028
1029 -------------------
1030 0.0.94 (2003-05-04)
1031 -------------------
1032

1041 -------------------
1042 0.0.93 (2003-03-28)
1043 -------------------
1044
1045 - colors for icc_gui
1046 - icc_gui sets volume directly (linux only)

1049 with unsufficient permissions
1050 - new command: hup to make all servers reread their configuration file
1051 - icecast meta data streaming
1052 - many small fixes and cleanups
