We are pleased to announce the release of CoreDNS-1.2.0!

In this release we have a new plugin, bump etcd to version 3 and bugfixes.

Core

Enable watch functionality when CoreDNS is used as a gRPC server (documented in the code - for now).

Plugins

• A new plugin called metadata was added. It adds metadata to a query, via the context.
• The etcd plugin now supports etcd version 3 (only!). It was impossible to support v2 and v3 at the same time (even as separate plugins); so we decided to drop v2 support.
• Fix a race/crash in the cache plugin when prefetch is enabled.
• The forward plugin has a prefer_udp option, that even when the incoming query is over TCP, the outgoing one will be tried over UDP first.
• secondary plugin has a bug fix for zone expiration: don’t expire zones if we can reach the primary, but see no zone changes.
• The auto plugin now works better with Kubernetes Configmaps.
