Upgrade to BIND version 9.8.3, the latest from ISC.

Browse Source 
Feature Change

*  BIND now recognizes the TLSA resource record type, created to
   support IETF DANE (DNS-based Authentication of Named Entities)

Bug Fix

*  The locking strategy around the handling of iterative queries
   has been tuned to reduce unnecessary contention in a multi-
   threaded environment.

Other critical bug fixes are included.

All BIND users are encouraged to upgrade.
