*   A new priority function ResourceLimitsPriorityMap (disabled by default and behind alpha feature gate and not part of the scheduler's default priority functions list) that assigns a lowest possible score of 1 to a node that satisfies one or both of input pod's cpu and memory limits, mainly to break ties between nodes with same scores.

- Fix handling of aws-load-balancer-security-groups annotation. Security-Groups assigned with this annotation are no longer modified by kubernetes which is the expected behaviour of most users. Also no unnecessary Security-Groups are created anymore if this annotation is used. ([#88689](https://github.com/kubernetes/kubernetes/pull/88689),...

* To allow the userspace proxy to work correctly on multi-interface hosts when using the non-default-route interface, you may now set the `bindAddress` configuration option to an IP address assigned to a network interface.  The proxy will use that IP address for any required NAT operations instead of the IP address of the interface which has the default route.
