Config-version has been upped from 39 to 40. Changes:
Added a new config option under death-message-conflict-broadcast, death-message-enable-namedmob, which is true by default.
Code (Text):
# Whether to enable namedmob messages. If disabled, namedmob messages
# will not be shown and will be replaced with mob.
# Default: true
death-message-enable-namedmob: true
