- Fixed a bug with dual stack clusters using the beta feature MultiCIDRServiceAllocator which could not create dual stack Services or Services with IPs in the secondary range. Users who wanted to use this feature in version 1.30 with dual stack clusters could work around the issue by setting the feature gate DisableAllocatorDualWrite to true.
