The CoreDNS team has released
[CoreDNS-1.6.0](https://github.com/coredns/coredns/releases/tag/v1.6.0).

The `-cpu` flag is removed from this version.

This release sports changes in the *file* plugin. A speed up in the *log* plugin and fixes in the
*cache* and *hosts* plugins.

Upcoming deprecation: the kubernetes *federation* plugin [will be moved
to](https://github.com/coredns/coredns/issues/3041) github.com/coredns/federation. This is likely to
happen in CoreDNS 1.7.0.

# Plugins

* The [*file*](/plugins/file) got lot of bug fixes and it now loads zones lazily on start, i.e. if the zonefile
  does not exist, it keeps trying with every reload period.
* The [*cache*](/plugins/cache) fixes a race.
* Multiple fixes in the [*route53*](/plugins/route53) plugin.
* And the [*kubernetes*](/plugins/kubernetes) removes the `resyncperiod` option.
* The [*host*](/plugins/host) appended entries from /etc/hosts on each (re-)parse, instead of
  overwriting them.
* Speed ups in the [*log*](/plugins/log) plugin.
