3751.	[tuning]	The default setting for the -U option (setting
			the number of UDP listeners per interface) has
			been adjusted to improve performance. [RT #35417]

                        in draft-andrews-dnsext-expire-00.  Retrivial of
                        remaining time to expiry from slave zones is supported.

                        EXPIRE uses an experimental option code (65002) and
                        is subject to change. [RT #35416]

3749.	[func]		"dig +subnet" sends an EDNS client subnet option
			containing the specified address/prefix when
                        querying. (Thanks to Wilmer van der Gaast.)
                        [RT #35415]

3747.	[bug]		A race condition could lead to a core dump when
			destroying a resolver fetch object. [RT #35385]

3746.	[func]		New "max-zone-ttl" option enforces maximum
			TTLs for zones. If loading a zone containing a
			higher TTL, the load fails. DDNS updates with
			higher TTLs are accepted but the TTL is truncated.
			(Note: Currently supported for master zones only;
			inline-signing slaves will be added.) [RT #38405]

3745.	[func]		"configure --with-tuning=large" adjusts various
			compiled-in constants and default settings to
			values suited to large servers with abundant
			memory. [RT #29538]

                        (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]
