Service APIs has been renamed to Gateway API. #536.

GatewayClass

  • The default status condition of GatewayClass resource is now Admitted:false instead of InvalidParameters:Unknown. #471.

Gateway

  • spec.listeners[].tls.mode now defaults to Terminate. #518.
  • Empty hostname in a listener matches all request. #525.

HTTPRoute

  • New set property has been introduced for HTTPRequestHeader Filter. Headers specified under set are overriden instead of added. #475.

  • Maximum limit for forwardTo has been increased from 4 to 16 for all route types. #493.

    • Header name matching must be case-insensitive.
    • Match tiebreaking semantics have been outlined in detail.
  • TCPRoute, TLSRoute, and UDPRoute:
