The same for FreeBSD, 1.10.rc1 has built fine and is running flawlessly
for over 24 hours in a production environment with RPZ config enabled.

>> The serve-stale functionality as described in

>> Both behaviors are available and can be configured with the various

>> The DSA algorithms have been disabled by default, this is because of
>> RFC 8624.
>>
>> There is a crash fix in the parse of text of type WKS, reported by
>> X41 D-Sec.
>>
>> In addition, neg and key caches can be shared with multiple
>> libunbound contexts, a change that assists unwind.  The
>> contrib/unbound_portable.service provides a systemd start file for a
>> portable setup.  The configure --with-libbsd option allows the use

>> Features:

>> - Added serve-stale functionality as described in

>> - Updated cachedb to honor `serve-expired-ttl`; Fixes #107.
>> - Renamed statistic `num.zero_ttl` to `num.expired` as expired replies
>>   come with a configurable TTL value (`serve-expired-reply-ttl`).
>> - Merge #135 from Florian Obser: Use passed in neg and key cache

>> - Fix #153: Disable validation for DSA algorithms.  RFC 8624 compliance.
