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]

                        declarations despite being documented.  This is
                        needed to support turning off forwarding and turning
                        on delegation only at the same name.  [RT #35392]

- require 5.006_001
- cut off the least significant figures of rrsig dates before
  comparison to avoid integer overflow

                        was declared. [RT #35387]

3741.	[func]		"delve" (domain entity lookup and validation engine):
			A new tool with dig-like semantics for performing DNS
			lookups, with internal DNSSEC validation, using the
			same resolver and validator logic as named. This
			allows easy validation of DNSSEC data in environments
			with untrustworthy resolvers, and assists with
			troubleshooting of DNSSEC problems. (Note: not yet
			available on win32.) [RT #32406]

3740.	[contrib]	Minor fixes to configure --with-dlz-bdb,
			--with-dlz-postgres and --with-dlz-odbc. [RT #35340]

3739.	[func]		Added per-zone stats counters to track TCP and
			UDP queries. [RT #35375]
