-# Upgrading to version 2 bootstrap configuration
-
-To support features such as streaming gRPC configuration and TLS, Contour has moved from Envoy's v1 JSON configuration format to the v2 YAML configuration format.
-
-This document describes the changes you must make to your Deployment or Daemonset manifest for Contour 0.2 (or earlier) to support the new format in Contour 0.3.
-
-### v1 JSON configuration will be removed in Contour 0.4
-
-Contour 0.3 deprecates the JSON bootstrap configuration format.
-Support for JSON configuration will be removed in Contour 0.4.
-
-## Change `config.json` to `config.yaml`
-
-In the `envoy` and `envoy-initconfig` container and init container respectively, change `/config/contour.json` to `/config/contour.yaml`.
-This causes Contour to emit a YAML bootstrap configuration file with the version 2 syntax.
