 ## bunyan 1.1.3 (not yet released)
 
-(nothing yet)
+- [issue #165] Include extra `err` fields in `bunyan` CLI output. Before
+  this change only the fields part of the typical node.js error stack
+  (err.stack, err.message, err.name) would be emitted, even though
+  the Bunyan *library* would typically include err.code and err.signal
+  in the raw JSON log record.
