b8a9632333 [master] complete NTA work
3882.	[func]		By default, negative trust anchors will be tested
			periodically to see whether data below them can be
			validated, and if so, they will be allowed to
			expire early. The "rndc nta -force" option
			overrides this behvaior.  The default NTA lifetime
			and the recheck frequency can be configured by the
			"nta-lifetime" and "nta-recheck" options. [RT #36146]

0cfb247368 [master] rndc nta
3867.	[func]		"rndc nta" can now be used to set a temporary
			negative trust anchor, which disables DNSSEC
			validation below a specified name for a specified
			period of time (not exceeding 24 hours).  This
			can be used when validation for a domain is known
			to be failing due to a configuration error on
			the part of the domain owner rather than a
			spoofing attack. [RT #29358]

b5f6271f4d 3744. [experimental] SIT: send and process Source Identity Tokens
(which are similar to DNS Cookies by Donald Eastlake)
                        and are designed to help clients detect off path
                        spoofed responses and for servers to detect legitimate
                        clients.

                        SIT use a experimental EDNS option code (65001).

                        SIT can be enabled via --enable-developer or
                        --enable-sit.  It is on by default in Windows.

                        RRL processing as been updated to know about SIT with
                        legitimate clients not being rate limited. [RT #35389]

86dcc40058 2930. [experimental] New "rndc addzone" and "rndc delzone" commads
allow dynamic addition and deletion of zones.
			To enable this feature, specify a "new-zone-file"
			option at the view or options level in named.conf.
			Zone configuration information for the new zones
			will be written into that file.  To make the new
			zones persist after a restart, "include" the file
			into named.conf in the appropriate view.  (Note:
			This feature is not yet documented, and its syntax
			is expected to change.) [RT #19447]
