+      ICANN is in the process of introducing a new Key Signing Key (KSK) for
+      the global root zone. BIND has multiple methods for managing DNSSEC
+      trust anchors, with somewhat different behaviors. If the root
+      key is configured using the <command>managed-keys</command>
+      statement, or if the pre-configured root key is enabled by using
+      <command>dnssec-validation auto</command>, then BIND can keep
+      keys up to date automatically. Servers configured in this way
+      will roll seamlessly to the new key when it is published in
+      the root zone. However, keys configured using the
+      <command>trusted-keys</command> statement are not automatically
+      maintained. If your server is performing DNSSEC validation
+      and is configured using <command>trusted-keys</command>, you are
+      advised to change your configuration before the root zone begins
+      signing with the new KSK. This is currently scheduled for
+      October 11, 2017.
