* Allow kube- and cloud-controller-manager to listen on ports up to 65535. ([#65860](https://github.com/kubernetes/kubernetes/pull/65860), [@sttts](https://github.com/sttts))
* Allow kube-scheduler to listen on ports up to 65535. ([#65833](https://github.com/kubernetes/kubernetes/pull/65833), [@sttts](https://github.com/sttts))

- This PR sets the --cluster-dns flag value to kube-dns service IP whether or not NodeLocal DNSCache is enabled. NodeLocal DNSCache will listen on both the link-local as well as the service IP. ([#84383](https://github.com/kubernetes/kubernetes/pull/84383), [@prameshj](https://github.com/prameshj))
- kube-dns add-on:

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions. (...

*   A new scheduling queue helps schedule the highest priority pending pod first. ([#55109](https://github.com/kubernetes/kubernetes/pull/55109),[ @bsalamat](https://github.com/bsalamat))
*   A Pod can now listen to the same port on multiple IP addresses.  ([#52421](https://github.com/kubernetes/kubernetes/pull/52421),[ @WIZARD-CXY](https://github.com/WIZARD-CXY))

### SIG AWS

In v1.13 we worked on tighter integrations of Kubernetes API objects with AWS services. These include three out-of-tree alpha feature releases:

1) Alpha for AWS ALB (Application Load Balancer) integration to Kubernetes Ingress resources.

* Performance test framework and basic tests for the IPAM controller, to simulate behavior of the four supported modes under lightly loaded and loaded conditions, where load is defined as the number of operations to perform as against the configured kubernetes. ([#61143](https://github.com/kubernetes/kubernetes/pull/61143), [@satyasm](https://github.com/satyasm))

cluster-internal resources installed by kubeadm will be overwritten when upgrading from v1.6 to v1.7. ([#47081](https://github.com/kubernetes/kubernetes/pull/47081), [@luxas](https://github.com/luxas))

* kubeadm deb/rpm packages: cAdvisor doesn't listen on `0.0.0.0:4194` without authentication/authorization because of the possible information leakage. The cAdvisor API can still be accessed via `https://{node-ip}:10250/stats/`, though. ([kubernetes/release#356](https://github.com/kubernetes/release/pull/356),...

* Implement alpha version of PreferAvoidPods ([#20699](https://github.com/kubernetes/kubernetes/pull/20699), [@jiangyaoguo](https://github.com/jiangyaoguo))
* Retry when apiserver fails to listen on insecure port ([#28797](https://github.com/kubernetes/kubernetes/pull/28797), [@aaronlevy](https://github.com/aaronlevy))

- Kube-apiserver: fix a memory leak when deleting multiple objects with a `deletecollection`. ([#105606](https://github.com/kubernetes/kubernetes/pull/105606), [@sxllwx](https://github.com/sxllwx))
