9 <h1>DisOrder Change History</h1>
11 <p>This file documents recent user-visible changes to <a
12 href="http://www.greenend.org.uk/rjk/disorder/">DisOrder</a>.</p>
14 <p><b>IMPORTANT</b>: you should read <a
15 href="README.upgrades.html">README.upgrades</a> before upgrading.</p>
17 <h2>Changes up to version 5.2</h2>
21 <h3>PulseAudio Support</h3>
25 <p>PulseAudio is now supported, if the support library is available at
26 build time. It is the default for client applications, reflecting its
27 widespread use in desktop environments.</p>
31 <h3>Changes To RTP Support</h3>
35 <p>Disobedience now has a menu to select the network playback API.</p>
37 <p><code>disorder-playrtp</code> now selects playback API using
38 a <code>--api</code> option. The old API-selection options remain
39 available but are deprecated and will be removed in the future.</p>
41 <p>RTP playback can now transmit to multiple unicast destinations, added
42 and removed on demand. This is controlled by the new <code>rtp_mode</code>
43 option. The motivating use case is a bridged network with high- and
44 low-capacity components. However it is may also be useful in a routed
45 network without multicast routing support.</p>
49 <h3>GStreamer support</h3>
53 <p>If it's detected at <tt>configure</tt> time, a new decoder
54 program <tt>disorder-gstdecode</tt> and a new tracklength
55 plugin <tt>tracklength-gstreamer</tt> are built. These use the GStreamer
56 library for filetype detection, audio decoding and sample-rate conversion,
57 among other features. Using these, DisOrder can play any audio file
58 supported by GStreamer.
60 <p>The decoder has a number of options for controlling the sample-rate and
61 audio format conversion, allowing various tradeoffs between quality and
62 processor time. (High-quality conversion can consume more processor time
63 than decoding, so this is potentially useful on very a small device such as
66 <p>The GStreamer decoder can also use ReplayGain information stored in
67 audio files' metadata to adjust playback volume, so that tracks with very
68 wide dynamic range don't sound really quiet in comparison. This
69 information can be added using tools such as <tt>mp3gain</tt>,
70 <tt>vorbisgain</tt>, or <tt>metaflac</tt>. This is turned on by default if
71 you use the decoder; you can choose between per-album or per-track
72 settings, or turn it off entirely, using command-line options.</p>
74 <p>The GStreamer decoder is not used by default, but it can be enabled
75 easily enough by dropping something like the following into the server
79 player *.flac execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
80 player *.mp2 execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
81 player *.mp3 execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
82 player *.ogg execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
83 player *.wav execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
86 tracklength *.flac tracklength-gstreamer
87 tracklength *.mp2 tracklength-gstreamer
88 tracklength *.mp3 tracklength-gstreamer
89 tracklength *.ogg tracklength-gstreamer
90 tracklength *.wav tracklength-gstreamer
99 <li>The CGI program now checks user passwords even when it runs as the
100 main jukebox user(!).</li>
102 <li>Disobedience doesn't crash when search terms change under its
105 <li>The CGI program doesn't crash on some POST requests.
112 <h2>Changes up to version 5.1.1</h2>
121 <li><code>player</code> and <code>tracklength</code> can now be used
122 without arguments to clear the lists, as per the documentation.</li>
124 <li>Tracks without a player are forgotten upon rescan.</li>
126 <li>The speaker process avoids splitting frames.</li>
129 <p>Thanks to Mark Wooding and Joe Birr-Pixton.</p>
135 <h2>Changes up to version 5.1</h2>
139 <h3>Removable Device Support</h3>
143 <p>The server will now automatically initiate a rescan when a filesystem is
144 mounted or unmounted. (Use the <tt>mount_rescan</tt> option if you want to
145 suppress this behavior.)</p>
147 <p>The server takes care not to hold audio files open unnecessarily, so
148 that devices can be unmounted even if tracks from them are currently being
153 <h3>Disobedience</h3>
157 <p>You can now edit the <tt>required-tags</tt> and <tt>prohibited-tags</tt>
158 global preferences in Disobedience
159 (<a href="http://code.google.com/p/disorder/issues/detail?id=29">issue
162 <p>The “Manage users” option is now more reliably greyed out if
163 it will not work. This depends on a server change too, so it may still be
164 wrong if a new Disobedience is used against an old server.</p>
166 <p>A <tt>.desktop</tt> file is now shipped, making Disobedience visible as
167 an application in freedesktop.org-compliant systems.</p>
175 <p>The Debian package now includes a cronjob that backs up the database
176 daily. See <tt>/etc/cron.d/disorder</tt>. You can put settings
177 in <tt>/etc/default/disorder</tt> to turn this off or to control how long
178 the backups are kept for.</p>
180 <p>The <tt>disorder-dump -r</tt> option was broken.</p>
182 <p><tt>disorder-dump</tt> now gets permissions right automatically (<a
183 href="http://code.google.com/p/disorder/issues/detail?id=56">issue
192 <p>Unicode support has been upgraded to <a
193 href="http://www.unicode.org/versions/Unicode6.0.0/">Unicode
196 <p>Client programs no longer depend on libdb.</p>
198 <p>The following have been removed:</p>
202 <li>The <tt>allow</tt>, <tt>gap</tt>, <tt>lock</tt>, <tt>prefsync</tt>,
203 <tt>restrict</tt>, <tt>trust</tt> configuration commands. If they still
204 appear in your configuration file then the server will not start.</li>
206 <li>The <tt>columns</tt> web interface option. It will generate an
207 message in your error log but otherwise be ignored.</li>
209 <li>The <tt>--wait-for-device</tt> player option. If it still appears in
210 any player commands, they will not work.</li>
212 <li>Support for automatically importing pre-3.0 users.</li>
216 <p>Various minor bug fixes.</p>
222 <h2>Changes up to version 5.0.3</h2>
226 <p><b>Security</b>: Local connections can no longer create and delete users
227 unless they are properly authorized.</p>
231 <h2>Changes up to version 5.0.2</h2>
235 <p>The login form now indicates that a cookie will be set.</p>
239 <h2>Changes up to version 5.0.1</h2>
243 <h3>Disobedience</h3>
247 <p>The sense of the Control → Playing menu item was fixed.</p>
253 <h2>Changes up to version 5.0</h2>
261 <p>The <tt>device</tt> configuration option now works under OS X.
263 be specified either by UID or name. Fixes <a
264 href="http://code.google.com/p/disorder/issues/detail?id=27">Issue
267 <p>Gapless play should be more reliable, and playback latency over RTP
268 should be a bit lower. Note though that all the sound output code has
269 been reorganized and in some cases completely rewritten, so it's possible
270 that bugs may have been (re-)introduced. Decoding of scratches is also
271 initiated ahead of time, giving more reliable playback.</p>
273 <p>The <tt>command</tt> backend now (optionally) sends silence instead
274 of suspending writes when a pause occurs or no track is playing.</p>
276 <p>If <a href="http://www.mega-nerd.com/SRC/">libsamplerate</a> is
277 available at build time then that will be used instead of invoking
278 <a href="http://sox.sourceforge.net/">SoX</a>. SoX support will be
279 removed in a future version.</p>
281 <p>The libao plugin has been removed, because the plugin API is not
282 usable in libao 1.0.0.</p>
284 <p>Playlists are now supported. These allow a collection of tracks to be
285 prepared offline and played as a unit.</p>
289 <h3>Disobedience</h3>
293 <p>Multiple tracks can now be dragged in the queue in a single operation.
294 Furthermore, it is now possible to drag tracks from the
295 “Recent”, “Added” and “Choose” tabs
298 <p>Disobedience now supports playlist editing and has a compact mode,
299 available from the <b>Control</b> menu.</p>
301 <p>Disobedience has a <a href="disobedience/manual/index.html">new
306 <h3>Web Interface</h3>
310 <p>Confirmation URLs should be cleaner (and in particular not end
311 with punctuation). (Please see <a
312 href="README.upgrades.html">README.upgrades</a> for more about this.)</p>
320 <p>There is a new <tt>--command</tt> option which allows the RTP player
321 to send audio data to a user-chosen command instead of an audio API. See
322 the man page for details.</p>
324 <p>The <tt>--device</tt> option to <tt>disorder-playrtp</tt> now works
325 under OS X (as above).</p>
333 <p>IPv6 should now work. Network address specifications
334 (<tt>listen</tt>, <tt>connect</tt> etc) can now be prefixed with
335 <tt>-4</tt> or <tt>-6</tt> to force use
336 of IPv4 or IPv6, though normally this should not be needed.</p>
338 <p>Unicode support has been upgraded to <a
339 href="http://www.unicode.org/versions/Unicode5.1.0/">Unicode

453 <h2>Changes up to version 4.3</h2>
457 <h3>Disobedience</h3>
461 <p>A bug was fixed in the calculation of how much of the track had
462 played. This would lead to the counter showing incorrect values in
463 various situations.</p>
465 <p>Disobedience's icons have been changed to larger, more colorful
466 ones. The SVG source is included if you want to fiddle with them.</p>
468 <p>“Select all” is now no longer available in the choose
469 tab. Instead there is a new “Select children” option which
470 selects the file children of a single subdirectory.</p>
478 <p>The selection bias for newly added tracks was reduced by half. You
479 can put it back to the old very neophilic value with
480 “<tt>new_bias 900000</tt>” in the config file.</p>
482 <p>It is now possible to ‘adopt’ randomly picked tracks.
483 Disobedience and the command-line client support this but the web
484 interface does not.</p>
486 <p>The default track name parsing was modified to handle filenames
487 generated by iTunes.</p>
491 <h3>Miscellaneous</h3>
495 <p><tt>disorderfm</tt> now preserves directory permissions.</p>
497 <p>DisOrder is now licensed under <a
498 href="http://www.gnu.org/licenses/gpl-3.0.html">GPL v3</a>. The main
499 goal is to prohibit <a
500 href="http://en.wikipedia.org/wiki/Tivoization">Tivoization</a>.</p>
502 <p>The build system will now automatically cope with Fink's broken GTK+
503 packages. There are a number of improvements to the Debian
506 <p>DisOrder now builds on 64-bit Linux systems.</p>
508 <p>There are various minor fixes.</p>
523 <td><a href="http://code.google.com/p/disorder/issues/detail?id=24">#24</a></td>
524 <td>Fails to build on ubuntu 8.10</td>
527 <td><a href="http://code.google.com/p/disorder/issues/detail?id=26">#26</a></td>
528 <td>Disobedience shows wrong track elapsed time after a pause</td>
535 <h2>Changes up to version 4.2</h2>
539 <h3>Disobedience</h3>
543 <p>The login window now has a 'remote' switch. If this is turned off
544 then Disobedience will connect to a local server. Formerly it would
545 always use TCP/IP.</p>
547 <p>The Delete and backspace keys will now remove tracks from the queue.
548 Escape will now dismiss the properties, users or login windows and return
549 now works in the login and properties windows.</p>
553 <h3>Documentation</h3>
557 <p>Track and global preferences are now described in a new
558 <b>disorder_preferences</b>(5) man page.</p>
573 <td><a href="http://code.google.com/p/disorder/issues/detail?id=21">#21</a></td>
574 <td>CGI should use PATH_INFO more sensibly</td>
582 <h2>Changes up to version 4.1.1</h2>
586 <p>Disobedience's “Login” window now works when you are logged
591 <h2>Changes up to version 4.1</h2>
595 <h3>Disobedience</h3>
599 <p>Disobedience has been largely rewritten:</p>
603 <li>All the tabs now use native GTK+ list/tree widgets, resulting in
604 greater speed in some cases and more consistency with other GTK+
607 <li>You can now use type-ahead find in the choose tab. The initiation
608 of a search is delayed slightly to avoid lots of updates when you're
609 half way through entering search terms.</li>
611 <li>The choose tab now shows track lengths.</li>
613 <li>Many buttons are now more reliably made insensitive when they can't
616 <li>You can now play tracks off the recent tab.</li>
620 <p>Disobedience attempts to cope with servers from older versions, up to
621 a point, but this is not well tested and it's best to keep the server
622 fully up to date.</p>
630 <p>When a track shares a directory with its alias, the real track name is
631 now returned instead of the alias (the opposite way round to the previous
637 <h2>Changes up to version 4.0.2</h2>
641 <p>Corrected web browser linked from Disobedience.</p>
645 <h2>Changes up to version 4.0.1</h2>
649 <p>Libtool and Automake now install the CGI correctly. As part of this,
650 <tt>cgidir</tt> has been renamed to <tt>cgiexecdir</tt>. The configure
651 script will report an error if you try to use the old name.</p>
655 <h2>Changes up to version 4.0</h2>
663 <p>The <tt>gap</tt> directive will no longer work. It could be
664 restored if there is real demand.</p>
666 <h4>Event Scheduling</h4>
670 <p>It is now possible to schedule events to occur in the future.
671 Currently the supported actions are playing a specific track, and
672 changing a global preference (thus allowing e.g. random play to be
673 turned on or off). See the <tt>schedule-*</tt>
674 commands described in disorder(1).</p>
678 <h4>Random Track Choice</h4>
682 <p>This has been completely rewritten to support new features:</p>
686 <li>tracks in the recently-played list or in the queue are no longer
687 eligible for random choice.</li>
689 <li>there is a new <tt>weight</tt> track preference allowing for
690 non-uniform track selection. See disorder(1) for details.</li>
692 <li>there is a new configuration item <tt>replay_min</tt> defining
693 the minimum time before a played track can be picked at random.
694 The default is 8 hours (which matches the earlier behaviour).</li>
696 <li>recently added tracks are biased up; see <tt>new_bias</tt> and
697 <tt>new_bias_age</tt> in disorder_config(5).</li>
703 <h4>Web Interface</h4>
707 <p>This has been largely rewritten. The most immediate benefits are:</p>
711 <li>the search page is integrated into the choose page, and
712 includes links to parent directories.</li>
714 <li>if you try to do something you have insufficient rights for,
715 instead of getting an error page or nothing happening, you are
716 redirected to the login page.</li>
720 <p>Customizers should find their lives easier: the syntax is less onerous, it
721 is possible to define macros to avoid repetition, and the documentation is
722 less monolithic (see disorder.cgi(8) as a starting point).</p>
724 <p>Mail is now sent via the system sendmail program, though it remains
725 possible to use TCP to connect to an SMTP server. See <tt>sendmail</tt> and
726 <tt>smtp_server</tt> in disorder_config(5).</p>
728 <p>The web interface is now installed automatically. If you don't want it,
729 use <tt>./configure --without-cgi</tt>. If you want it in a non-default
730 location, or no location for it is detected, set <tt>cgidir</tt>
731 and <tt>httpdir</tt> on the <tt>./configure</tt> command line.</p>
737 <h3>Disobedience</h3>
741 <p>There is now a new user management window. From here you can add and
742 remove users or modify their settings.</p>
744 <p>Relatedly, the server will only allow remote user management if you set
745 <tt>remote_userman</tt> to <tt>yes</tt>.</p>
749 <h3>Miscellaneous</h3>
753 <p><tt>scripts/setup</tt> now honors command line options, and can
754 set up network play as well as the local default sound device.</p>

810 <h2>Changes up to version 3.0.2</h2>
814 <p>Builds <tt>--without-server</tt> should work again.</p>
816 <p>The web interface is a bit more liberal in the cookie value
817 syntax it will accept.</p>
819 <p>Clients fail more gracefully if no password is available.</p>
823 <h2>Changes up to version 3.0.1</h2>
827 <p>Debian upgrades from 2.0.x should now work better.</p>
831 <h2>Changes up to version 3.0</h2>
835 <p><b>Important</b>! See <a
836 href="README.upgrades.html">README.upgrades</a> when upgrading.</p>
838 <h3>Platforms And Installation</h3>
842 <p>Mac OS X and FreeBSD are somewhat supported. There is now a bash
843 script in <tt>scripts/setup</tt> which will automate the setup after
844 <tt>make install</tt>.</p>
852 <p>Users are now stored in the database rather than a configuration
855 <p>The server now has a built-in list of stopwords and players, so
856 only additions to these need be mentioned in the configuration file.</p>
858 <p>The default inter-track gap is now 0s.</p>
860 <p>How sound is played is now controlled via the new <tt>api</tt>
861 configuration command. This also controls how the volume is set,
862 which now works with ALSA as well as OSS.</p>
864 <p>A bug in the MP3 decoder was fixed (also in 2.0.4).</p>
868 <h3>Web Interface</h3>
872 <p>The web interface now uses cookies to remember user identity, and
873 allows online registration of new users. Also it is no longer
874 necessary to manually specify the URL of the web interface (but you
875 can override it if you don't like the value it figures out).</p>
877 <p>It is possible to allow users to register via the web interface.</p>
879 <p>The web interface's browser support has been improved. It has
880 been tested with Firefox 2, Safari 3, Konqueror 3, Internet Explorer
885 <h3>Disobedience</h3>
889 <p>A bug which would cause a crash if you attempt to rearrange the
890 queue while no track was playing has been fixed. There is a new
891 'deselect all tracks' option, mirroring 'select all tracks.</p>
