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]
3524. [func] Added an alternate statistics channel in JSON format,
when the server is built with the json-c library:
http://[address]:[port]/json. [RT #32630]
3506. [func] When setting "max-cache-size" and "max-acache-size",
the keyword "unlimited" is no longer defined as equal
to 4 gigabytes (except on 32-bit platforms); it
means literally unlimited. [RT #32358]
3505. [bug] When setting "max-cache-size" and "max-acache-size",
larger values than 4 gigabytes could not be set
explicitly, though larger sizes were available
when setting cache size to 0. This has been
corrected; the full range is now available.

new stats that were added for 9.10 (changes 3319-3326) were not
all updated when the new statistics schema was merged (change 3418).

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.

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]
iteration self tuning. The covers nodes clean from
the cache per iteration, nodes written to disk when
rewriting a master file and nodes destroyed per
iteration when destroying a zone or a cache.
