 The floating-point processing takes advantage of the DSP acceleration afforded by the ARM M4F core inside the Teensy 3.5/3.6 processor.  Therefore, it uses `arm_math.h`.  This dependencies is installed automatically when you install the Teensy Audio Library, so you don't need to take any extra steps.  It's there already.
 
+Status
+------
+
+The following table summarizes the status, as of 24 November 2020.  I will try to keep this up-to-date as work continues, but tere will be lags.
+Thus there may be more T4.x compatibility than shown here.  A blank entry for status does not indicate a problem, but rather a lack
+ofverification.  Further rexamples will come to test some of these objects.
