- Fix clearing of rate-limiter for the queue of checks for cleaning stale pod disruption conditions. 
  The bug could result in the PDB synchronization updates firing too often or the pod disruption cleanups taking too long to happen. ([#114780](https://github.com/kubernetes/kubernetes/pull/114780), [@mimowo](https://github.com/mimowo)) [SIG Apps]

- Fixed a bug where startupProbe stopped working after a container's first restart ([#101093](https://github.com/kubernetes/kubernetes/pull/101093), [@wzshiming](https://github.com/wzshiming)) [SIG Node]
- Fixed port-forward memory leak for long-running and heavily used connections. ([#99839](https://github.com/kubernetes/kubernetes/pull/99839), [@saschagrunert](https://github.com/saschagrunert)) [SIG API Machinery and Node]

  and `sync_partial_proxy_rules_duration_seconds` (in addition to the existing
  `sync_proxy_rules_duration_seconds`), to give better information about how long
  each sync type is taking, rather than only giving a weighted average of the two
  sync types together. ([#117787](https://github.com/kubernetes/kubernetes/pull/117787), [@danwinship](https://github.com/danwinship)) [SIG Network]

pod autoscaler. Note that it doesn't include some features of Heapster, such as short term metrics for graphs in kube-dashboard and dedicated push sinks, which proved hard to maintain and scale. Clusters using Heapster for transferring metrics into long-term storage should consider using their metric solution's native Kubernetes support, if present, or should consider alternative solutions.
