- Fix cronjob controller handling of complex schedules, like "30 6-16/4 * * 1-5", for example ([#119137](https://github.com/kubernetes/kubernetes/pull/119137), [@kmala](https://github.com/kmala)) [SIG Apps]

* When using IP aliases, use a secondary range rather than subnetwork to reserve cluster IPs. ([#51690](https://github.com/kubernetes/kubernetes/pull/51690), [@bowei](https://github.com/bowei))
* IPAM controller unifies handling of node pod CIDR range allocation. ([#51374](https://github.com/kubernetes/kubernetes/pull/51374), [@bowei](https://github.com/bowei))
    * It is intended to supersede the logic that is currently in range_allocator

- Fixes calculating the requeue time in the cronjob controller, which results in properly handling failed/stuck jobs ([#121540](https://github.com/kubernetes/kubernetes/pull/121540), [@soltysh](https://github.com/soltysh)) [SIG Apps]
