The CoreDNS team has released CoreDNS-1.6.5.

A fairly small release that polishes various plugins and fixes a bunch of bugs.

Plugins

A new plugin transfer that encapsulates the zone transfer knowledge and code in one place. This makes it easier to add this functionality to new plugins. Plugins that already implement zone transfers are expected to move to it in the 1.7.0 release.

• forward don’t block on returning sockets; instead timeout and drop the socket on the floor, this makes each go-routine guarantee to exit.
• kubernetes adds metrics to measure kubernetes control plane latency, see documentation for details.
• file fixes a panic when comparing domains names.
