+### What ECMAScript 2019 features do you support?
+
+Because ECMAScript 2019 is still under development, we are implementing features as they are finalized. Currently, Espree supports:
+
+* Optional `catch` binding
+* JSON superset (`\u2028` and `\u2029` in string literals)
+
 ### How do you determine which experimental features to support?
 
 In general, we do not support experimental JavaScript features. We may make exceptions from time to time depending on the maturity of the features.
