 **Added**
 
-- :pull:`1165` - Allow concurrent renders of discrete component tree - enable this
+- :pull:`1165` - Allow asynchronously rendering discrete component tree - enable this
   experimental feature by setting `REACTPY_ASYNC_RENDERING=true`. This should improve
   the overall responsiveness of your app, particularly when handling larger renders
   that would otherwise block faster renders from being processed.
