* Fixes validation of VolumeAttachment API objects created with inline volume sources. ([#80945](https://github.com/kubernetes/kubernetes/pull/80945), [@tedyu](https://github.com/tedyu))
* Fix kubelet errors in AArch64 with huge page sizes smaller than 1MiB ([#78495](https://github.com/kubernetes/kubernetes/pull/78495), [@odinuge](https://github.com/odinuge))

* Scale max-inflight limits together with master VM sizes. ([#73268](https://github.com/kubernetes/kubernetes/pull/73268), [@wojtek-t](https://github.com/wojtek-t))
* Update to go1.10.8 ([#73329](https://github.com/kubernetes/kubernetes/pull/73329), [@ixdy](https://github.com/ixdy))

- Scale max-inflight now limits together with master VM sizes. ([#73268](https://github.com/kubernetes/kubernetes/pull/73268), [@wojtek-t](https://github.com/wojtek-t))

- Kube-apiserver metrics will now include request counts, latencies, and response sizes for /healthz, /livez, and /readyz requests. ([#83598](https://github.com/kubernetes/kubernetes/pull/83598), [@jktomer](https://github.com/jktomer)) [SIG API Machinery]

### Other (Cleanup or Flake)

- Added the `Step` field to the testing framework to allow volume expansion in configurable step sizes for tests. ([#134760](https://github.com/kubernetes/kubernetes/pull/134760), [@Rishita-Golla](https://github.com/Rishita-Golla)) [SIG Storage and Testing]

- Added metric `apiserver_watch_events_sizes` that can be used to estimate sizes of watch events in the system. ([#80477](https://github.com/kubernetes/kubernetes/pull/80477), [@mborsz](https://github.com/mborsz))

* Scale max-inflight limits together with master VM sizes. ([#73268](https://github.com/kubernetes/kubernetes/pull/73268), [@wojtek-t](https://github.com/wojtek-t))
* Update to go1.10.8 ([#73379](https://github.com/kubernetes/kubernetes/pull/73379), [@cblecker](https://github.com/cblecker))

- Added `SizeBasedListCostEstimate` feature gate that allowed apiserver to estimate sizes of objects to calculate cost of LIST requests. ([#132355](https://github.com/kubernetes/kubernetes/pull/132355), [@serathius](https://github.com/serathius)) [SIG API Machinery and Etcd]

  Controller Manager flags for the node IPAM controller have slightly changed:
  1. When configuring a dual-stack cluster, the user must specify both `--node-cidr-mask-size-ipv4` and `--node-cidr-mask-size-ipv6` to set the per-node IP mask sizes, instead of the previous `--node-cidr-mask-size` flag.
  2. The `--node-cidr-mask-size` flag is mutually exclusive with `--node-cidr-mask-size-ipv4` and `--node-cidr-mask-size-ipv6`.

- The `HugePageStorageMediumSize` feature graduates to GA and unconditionally enabled. Allowing unconditional usage of multiple sizes huge page resources on a container level. ([#99144](https://github.com/kubernetes/kubernetes/pull/99144), [@bart0sh](https://github.com/bart0sh))
