*   Fix to ignore extended resources that are not registered with kubelet during container resource allocation. ([#53547](https://github.com/kubernetes/kubernetes/pull/53547),[ @jiayingz](https://github.com/jiayingz))


#### **Container Runtime**

* Copy and display source location prominently on Kubernetes instances ([#27985](https://github.com/kubernetes/kubernetes/pull/27985), [@maisem](https://github.com/maisem))
* Federation e2e support for AWS ([#27791](https://github.com/kubernetes/kubernetes/pull/27791), [@colhom](https://github.com/colhom))

- Added a new IPAddress object kind

- During device plugin allocation, resources requested by the pod can only be allocated if the device plugin has registered itself to kubelet AND healthy devices are present on the node to be allocated. If these conditions are not sattisfied, the pod would fail with `UnexpectedAdmissionError`...

- Switched intstr.Type to sized integer to follow API guidelines and improve compatibility with proto libraries ([#83956](https://github.com/kubernetes/kubernetes/pull/83956), [@liggitt](https://github.com/liggitt))
- Client-go: improved allocation behavior of the delaying workqueue when handling objects with far-future ready times. ([#83945](https://github.com/kubernetes/kubernetes/pull/83945), [@barkbay](https://github.com/barkbay))

- Fix: ignore the case when updating Azure tags (#104687, @nilo19) [SIG Cloud Provider]
- Revert PR #102925 which introduced unexpected scheduling behavior based on balanced resource allocation (#105239, @damemi) [SIG Scheduling]
- Updates golang.org/x/text to v0.3.6 to fix CVE-2020-28852 (#102602, @jonesbr17) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Node]

### Serverside Apply - Beta 2

For more information, see [#53288](https://issue.k8s.io/53288).

  * Enable kubelet csr bootstrap in GCE/GKE ([#40760](https://github.com/kubernetes/kubernetes/pull/40760), [@mikedanese](https://github.com/mikedanese))

  * Adds support for allocation of pod IPs via IP aliases. ([#42147](https://github.com/kubernetes/kubernetes/pull/42147), [@bowei](https://github.com/bowei))
