- GeoIP plugin will change behavior for missing latitude/longitude: currently returns 0, but will return empty string in next release
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.
