We are delighted to present version v1.28.3 of Contour, our layer 7 HTTP reverse proxy for Kubernetes clusters.

All Changes

Update Envoy to v1.29.3

See the release notes for v1.29.3 here.

Note that this Envoy version retains the hop-by-hop TE header when set to trailers, fixing a regression seen in v1.29.0-v1.29.2 for HTTP/2, particularly gRPC. However, this version of Contour continues to set the envoy.reloadable_features.sanitize_te Envoy runtime setting to false to ensure seamless upgrades. This runtime setting will be removed in Contour v1.29.0.

Update Go to v1.21.9

See the release notes for v1.21.9 here.
