Major Changes since v1.3.0

Breaking Changes

Experimental CORS Support in HTTPRoute - Breaking Change for AllowCredentials Field

Users of the Experimental CORS AllowCredentials field can now specify false.
The underlying API specification type has changed from a enum of type boolean to
just a boolean, so users deploying HTTPRoutes via libraries and evaluating the
experimental CORS support will need to adjust for the change in types. Please
see #3895 for more details.

Standard GRPCRoute - Spec Field Required (Technicality)

This PR makes grpcroute.spec a required field. This is technically a
backward-incompatible change, as previously the field was unintentionally
treated as optional because we erroneously used omitempty on .spec (unlike
other APIs). Since the codebase didn't yet enforce explicit required markers,
that omitempty allowed a missing .spec.

Because .spec contains essential route configuration, omitting it renders a
GRPCRoute unusable and causes route implementation to fail, so we expect this
change will not have adverse effects, but wanted to call it out all the same.
Please see #3937 for more details.
