                        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]

3329.	[bug]		Handle RRSIG signer-name case consistently: We
			generate RRSIG records with the signer-name in
			lower case.  We accept them with any case, but if
			they fail to validate, we try again in lower case.
			[RT #27451]

This includes the following changes:

3326.	[func]		Added task list statistics: task model, worker
			threads, quantum, tasks running, tasks ready.
			[RT #27678]

3325.	[func]		Report cache statistics: memory use, number of
			nodes, number of hash buckets, hit and miss counts.
			[RT #27056]

3324.	[test]		Add better tests for ADB stats [RT #27057]

3323.	[func]		Report the number of buckets the resolver is using.
			[RT #27020]

3322.	[func]		Monitor the number of active TCP and UDP dispatches.
			[RT #27055]

3321.	[func]		Monitor the number of recursive fetches and the
			number of open sockets, and report these values in
			the statistics channel. [RT #27054]

3320.	[func]		Added support for monitoring of recursing client
			count. [RT #27009]

3319.	[func]		Added support for monitoring of ADB entry count and
			hash size. [RT #27057]

                        waiting for a single query (<qname,qtype,qclass>) to
                        resolve.  New options clients-per-query and
                        max-clients-per-query.

                        and drop them.  New stats category "duplicates".

inline and remove dns_stats_ncounters(), which just returned the public
constant DNS_STATS_NCOUNTERS.
