- The service controller will now retry creating the load balancer when `persistUpdate` fails due to conflict. ([#68087](https://github.com/kubernetes/kubernetes/pull/68087), [@grayluck](https://github.com/grayluck))

and similar tools also use an **internal cache** when building the image, if a file hasn't changed since the last time building the container image, then it will **reuse the same layer** created the last time, instead of copying the file again and creating a new layer from scratch.
