Even though the capacity to query SetupAuditTrail
object was introduced in Winter '16, it seems targeted mostly for reporting or human-readable purposes since the affected metadata (for changes that do affect metadata) and the action applied to it (create, modify, delete) is located in the Display
field, which is also dependant on the language of the user issuing the query.
Is there a way to obtain the metadata component being altered without having to parse the Display
message?
