[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]

[master] unify internal and export libraries 3550. [func] Unified the internal and export versions of the BIND libraries, allowing external clients to use the same libraries as BIND. [RT #33131]

[master] add JSON statistics channel 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]

[master] accept >4g max-{,a}cache-size 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. [RT #32358]
