kubernetes-sigs/gateway-api v0.1.0-rc2

v1alpha1: Release Candidate 2

on GitHub

This is our second v1alpha1 release candidate. The working group expects that this release candidate is quite close to the final v1alpha API and does not plan to make major API changes. However, minor (possibly breaking) API changes such as renaming fields are still possible.

This release candidate is suitable for implementors, but the working group does not recommend shipping products based on a release candidate API due to the possibility of incompatible changes prior to the final release.
