Coredns 1.8.5

+++ title = "CoreDNS-1.8.5 Release" description = "CoreDNS-1.8.5 Release Notes." tags = ["Release", "1.8.5", "Notes"] release = "1.8.5" date = 2021-09-10T07:00:00+00:00 author = "coredns" +++

This is a rather big release, we now share plugins among zones in the same server block, which should save memory. Various bug fixes in a bunch of plugins and not one, but two new plugins. A geoip plugin that can report where the query came from and a header plugin that allows you to fiddle with (some of) the header bits in a DNS message.

With this release, the coredns_cache_misses_total metric is deprecated. It will be removed in a later release. Users should migrate their promQL to use coredns_cache_requests_total - coredns_cache_hits_total.
