The CoreDNS team has released CoreDNS-1.6.4.

Various code cleanups and documentation improvements. We’ve added one new plugin: acl, that allows blocking requests.

Plugins

• acl block request from IPs or IP ranges.
• kubernetes received some bug fixes, see below for specific PRs.
• hosts exports metrics on the number of entries and last reload time.
