CoreDNS-003 has been [released](https://github.com/coredns/coredns/releases)!
CoreDNS is a DNS server that chains plugins, where each plugin implements a DNS feature.
# What is New
## Core
Refused queries are properly logged and exported if metrics are enabled.
## Plugin improvements
* *proxy*: allow `/etc/resolv.conf` to be used in the configuration.
* *metrics*: add tests and normalize some of the metrics. Removed the AXFR size metrics.
* *cache*: Added size and capacity of the cache (for both `denial` and `success` cache types).
Don't cache meta data records and zone transfers.
* *dnssec*: metrics were unused, hooked them up: export size and capacity of the signature cache.
* *loadbalance*: balance MX records as well.
* *auto*: numerous bugfixes.
* *file*: fix data race in reload process and also reload a zone when it is `mv`ed (newly created) into place.
Also rewrite the zone lookup algorithm and be more standards compliant, esp. in the area of DNSSEC, wildcards and empty-non-terminals; handle secure delegations.
* *kubernetes*: vendor the k8s dependency and updates to be compatible with Kubernetes 1.4 and 1.5.
Multiple cleanups and fixes. Kubernetes services can now be resolved.
