			"auto", which activates DNSSEC validation using the
			IANA root key. (The default can be changed back to
			"yes", which activates DNSSEC validation only when keys
			are explicitly configured in named.conf, by building
			BIND with "configure --disable-auto-validation".)

			EDNS CLIENT-SUBNET option (which was experimental
			and not practical to deploy) has been removed.

			The ECS option is still supported in dig and mdig
			via the +subnet option, and can be parsed and logged
			when received by named, but it is no longer used
			for ACL processing. The "geoip-use-ecs" option
			is now obsolete; a warning will be logged if it is
			used in named.conf. "ecs" tags in an ACL definition
			are also obsolete and will cause the configuration
			to fail to load.  [GL #32]

4724.	[func]		By default, BIND now uses the random number
			functions provided by the crypto library (i.e.,
			OpenSSL or a PKCS#11 provider) as a source of
			randomness rather than /dev/random.  This is
			suitable for virtual machine environments
			which have limited entropy pools and lack
			hardware random number generators.

			This can be overridden by specifying another
			entropy source via the "random-device" option
			in named.conf, or via the -r command line option;
			however, for functions requiring full cryptographic
			strength, such as DNSSEC key generation, this
			cannot be overridden. In particular, the -r
			command line option no longer has any effect on
			dnssec-keygen.

			This can be disabled by building with
			"configure --disable-crypto-rand".
