- Client-go: default informer behavior now updates store state with all the objects in a list or relist, before calling handler OnDelete/OnAdd/OnUpdate methods for individual items which were deleted/added/removed. This ensures that the store state which can be inspected by handlers actually corresponds to a set of objects that existed at a particular resource version on the server. This behavior...
