This release improves plugin reliability and standards compliance, adding startup timeout to the Kubernetes
|
|
|
|
|
plugin, fallthrough to gRPC, and EDNS0 unset to rewrite. The file plugin now preserves SRV record case per
|
|
|
|
|
RFC 6763, route53 is updated to AWS SDK v2, and multiple race conditions in cache and connection handling in
|
|
|
|
|
forward are fixed.
