v1.14.2

Compare Source

This release adds the new proxyproto plugin to support Proxy Protocol and preserve
client IPs behind load balancers. It also includes enhancements such as improved DNS
logging metadata and stronger randomness for loop detection (CVE-2026-26018), along
with several bug fixes including TLS+IPv6 forwarding, improved CNAME handling and
rewriting, allowing jitter disabling, prevention of an ACL bypass (CVE-2026-26017),
and a Kubernetes plugin crash fix. In addition, the release updates the build to
Go 1.26.1, which include security fixes addressing CVE-2026-27137, CVE-2026-27138, CVE-2026-27139,
CVE-2026-25679, and CVE-2026-27142.
