API Upgrade Guide
OpenKruise API is migrating from v1alpha1 to v1beta1. The upgrade process is smooth within several versions since conversion webhook is used. However, conversion webhook incur performance and resilience overheads, and the users are suggested to upgrade their applications to v1beta1 before upgrading OpenKruise.
