+- DNS Server local end points support to allow specifying alternate ports for UDP and TCP protocols.
+- DNS Server performance issues caused by thread contention fixed.
+- CNAME cloaking implemented to block domain names that resolve to CNAME which are blocked.
+- New Block List zone implementation that uses very less memory allowing to load block lists with millions of domain names even on a Raspberry Pi with 1GB RAM.
+- QNAME minimization support in recursive resolver [draft-ietf-dnsop-rfc7816bis-04](https://tools.ietf.org/html/draft-ietf-dnsop-rfc7816bis-04).
+- ANAME propriety record support to allow using CNAME like feature at zone root.

+- Added secondary zones with NOTIFY implementation [RFC 1996](https://tools.ietf.org/html/rfc1996).
+- Added stub zones with feature to override records.

+- Conditional forwarder zones with feature to override records.
