+Audio support
+'''''''''''''
+
+Since version 1.8.5, Futatabi has limited audio support. It is recorded
+(assuming Nageru is also at version 1.8.5 or newer) and saved for all inputs,
+and played back when showing a replay, but only when the replay speed is at
+100%, or very close to it. (At other speeds, you will get silence.)
+Furthermore, there is no local audio output; the Futatabi operator will not
+hear any audio, unless they use a video player into the Futatabi stream locally
+(with associated delay). All of this may change in the future.

+White balance
+'''''''''''''
+
+Since version 1.9.2, Futatabi will integrate with Nageru for white balance;
+the white balance set in Nageru will be recorded, and properly applied on
+playback (including fades). Note that this assumes you are using the built-in
+white balance adjustment (new in 1.9.2), not adding WhiteBalanceEffect manually
+to the scene; see :ref:`white-balance` for an example.
