Release Notes

coredns/coredns (coredns/coredns)

v1.13.2

Compare Source

This release adds initial support for DoH3 and includes several core performance and stability
fixes, including reduced allocations, a resolved data race in uniq, and safer QUIC listener
initialization. Plugin updates improve forwarder reliability, extend GeoIP schema support,
and fix issues in secondary, nomad, and kubernetes. Cache and file plugins also receive
targeted performance tuning.

Deprecations: The GeoIP plugin currently returns 0 for missing latitude/longitude, even though
0,0 is a real location. In the next release, this behavior will change: missing coordinates
will return an empty string instead. This avoids conflating “missing” with a real coordinate.
Users relying on 0 as a sentinel value should update their logic before this change takes effect.
See PR #​7732 for reference.
