- options named.conf statement *must* now come before any zone or view

statements. - Post-load of named.conf check verifies a slave zone has non-empty list of masters defined. - New per-zone boolean: enable-zone yes | no ; - intended to let a zone be disabled without having to comment out the entire zone statement. - New global and per-view option: max-cache-ttl number - New global and per-view option: addition-data internal | minimal | maximal;
