 ### Production readiness state
 
+Beginning with Version 0.3.11 we maintain a production readiness
+state for individual new features, since we expect that new
+features will first be released with an "alpha" or "beta" readiness
+state and over time move to full "production readiness".
+
+The following table has the general readiness state, the table below
+covers individual newer features separately.
