BIND ARM contains redundant and confusing information
In most/all versions of the BIND 9 Administrator Reference Manual 9.11-S, 9.16 and 9.18, in the section Feature Changes there is the following statement:
The default value of max-stale-ttl has changed from 1 week to 12 hours.
This change happened in 9.16.4 as a result of GL#1877 and the default value has changed again since then, so the statement should have been removed from later editions of the ARM, or updated to reflect the new value.
Please can it be removed going forward. Thanks.
