Message:

Re-purpose wp_die() for ajax responses.

  • Allows unit testing of core ajax actions.
  • wp_die() now has separate filters to choose a handler depending on the context (ajax, XML-RPC, else).
  • wp_die) in ajax context does not need to be called with a string. Conversion takes place before die().

props kurtpayne, see #15327.
