* kubectl delete does not use reapers for removing objects anymore, but relies on server-side GC entirely ([#63979](https://github.com/kubernetes/kubernetes/pull/63979), [@soltysh](https://github.com/soltysh))

- The formerly publicly-available cAdvisor web UI that the kubelet started using `--cadvisor-port` has been entirely removed in 1.12. The recommended way to run cAdvisor if you still need it, is via a DaemonSet. ([#65707](https://github.com/kubernetes/kubernetes/pull/65707), [@dims](https://github.com/dims))

- Fixed a scheduler preemption issue where the victim pod was not deleted due to incorrect status patching. This issue occurred when the preemptor and victim pods had different QoS classes in their status, causing the preemption to fail entirely. ([#126644](https://github.com/kubernetes/kubernetes/pull/126644), [@Huang-Wei](https://github.com/Huang-Wei))

  - The `metadata.selfLink` field is deprecated in individual and list objects. It will no longer be returned starting in v1.20, and the field will be removed entirely in v1.21. ([#80978](https://github.com/kubernetes/kubernetes/pull/80978), [@wojtek-t](https://github.com/wojtek-t))

- Removing the KUBECTL_OPENAPIV3_PATCH environment variable entirely, since aggregated discovery has been stable from 1.30. ([#134130](https://github.com/kubernetes/kubernetes/pull/134130), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI]

* API: the metadata.selfLink field is deprecated in individual and list objects. It will no longer be returned starting in v1.20, and the field will be removed entirely in v1.21. ([#80978](https://github.com/kubernetes/kubernetes/pull/80978), [@wojtek-t](https://github.com/wojtek-t))

- Skipped pod backoff entirely when the `PodMaxBackoffDuration` kube-scheduler option was set to zero and the `SchedulerPopFromBackoffQ` feature gate was enabled. ([#131965](https://github.com/kubernetes/kubernetes/pull/131965), [@macsko](https://github.com/macsko))
