We are pleased to announce the release of version 1.17.1 of the Unbound recursive DNS resolver.
This release fixes a number of bugs. There are also new configuration options that by default do not change the existing behaviour of Unbound.
With statistics-inhibit-zero the printout of zero values by stats can be controlled. Similarly with max-sent-count and max-query-restarts the iterator behaviour can be controlled. The maximum CNAME chain length that is accepted can be changed by increasing the max-query-restarts number. This takes more time to follow those elements.
The keep-cache option allows reloads to change configuration whilst keeping the cache memory intact, making the cache hot for good response times after the change has completed.
The release contains an additional fix for service downgrade due to wrong hash values for wildcards in a hyperlocal zone, that was reported by Sergey Kacheev.
