+==========
+
+This release integrates Xaekai's added support for Bandcamp, BitChute, Odysee,
+and Nicovideo playback support into the main repository.  The updated support
+for custom fonts and audio tracks in custom media manifests is also included,
+but does not work out of the box -- it requires a separate channel script; this
+may be addressed in the future.

       RTMP streams are only supported through the existing `rt:` media

   * `audio/aac`
-  * `audio/ogg`
+  * `audio/mp4`
   * `audio/mpeg`
+  * `audio/ogg`
 
 Other audio or video formats, such as AVI, MKV, and FLAC, are not supported due
 to lack of common support across browsers for playing these formats.  For more
 information, refer to
 [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Supported_media_formats#Browser_compatibility).
 
+### Audio Track Format ###
+
+Each audio track entry is a JSON object with the following keys:
+
+  * `label`: A label for the audio track.  This is displayed in the menu for the
+    viewer to select a text track.
+  * `language`: A two or three letter IETF BCP 47 subtype code indicating the
+    language of the audio track.
+  * `url`: A valid URL that browsers can use to retrieve the track.  The URL
+    must resolve to a publicly-routed IP address, and must use the `https:` scheme.
+  * `contentType`: A string representing the MIME type of the track at `url`.
+    Any type starting with `audio` from the list above is acceptable. However
+    the usage of audio/aac is known to cause audio syncrhonization problems
+    for some users. It is recommended to use an m4a file to wrap aac streams.
+
+**Important note regarding audio tracks:**
+
+Because of browsers trying to be too smart for their own good, you should
+include a silent audio stream in the video sources when using separate audio
+tracks. If you do not, the browser will automatically pause the video whenever
+the browser detects the page as not visible. There is no way to instruct it to
+not do so. You can readily accomplish the inclusion of a silent audio track
+with ffmpeg using the anullsrc filter like so:
+`ffmpeg -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=48000 -i input.mp4 -c:v copy -c:a aac -shortest output.mp4`
+It is recommended to match the sample rate and codec you intend to use in your
+audioTracks in your silent track.
+
 ### Text Track Format ###
 
 Each text track entry is a JSON object with the following keys:
 
-
   * `url`: A valid URL that browsers can use to retrieve the track.  The URL
     must resolve to a publicly-routed IP address, and must the `https:` scheme.

 --------|------------
 Synchronize video playback | By default, CyTube attempts to synchronize the video so that everyone is watching at the same time.  Some users with poor internet connections may wish to disable this in order to prevent excessive buffering due to constantly seeking forward.
 Synch threshold | The number of seconds your video is allowed to be ahead/behind before it is forcibly seeked to the correct position.  Should be set to at least 2 seconds to avoid buffering problems and choppy playback.
-Set wmode=transparent | There's probably no reason to touch this unless you know what you're doing.  Having a non-transparent wmode can cause modals to display behind the video player, but also can cause performance issues in some situations.
 Remove the video player | Automatically remove the video player on page load.  Equivalent to manually clicking Layout->Remove Video every time you load a channel.
 Hide playlist buttons by default | Hides the control buttons from each video in the playlist, so that only the title is displayed.  The control buttons can be shown by right clicking the video item in the playlist.
 Old style playlist buttons | Legacy feature introduced in CyTube 2.0 for those who preferred the old 1.0-style video control buttons.
