- Ginkgo: when e2e tests are invoked through ginkgo-e2e.sh, the default now is to use color escape sequences only when connected to a terminal. `GINKGO_NO_COLOR=y/n` can be used to override that default.

* Fix kubelet to correctly umounts mount points for glusterfs when transport endpoint is not connected and nfs when there is a stale file handle ([#58660](https://github.com/kubernetes/kubernetes/pull/58660), [@humblec](https://github.com/humblec))

## Known Issues

- There is a known issue [coredns/coredns#2629](https://github.com/coredns/coredns/issues/2629) in CoreDNS 1.3.1, wherein if the Kubernetes API shuts down while CoreDNS is connected, CoreDNS will crash. The issue is fixed in CoreDNS 1.4.0 in [coredns/coredns#2529](https://github.com/coredns/coredns/pull/2529).

- kube-apiserver: setting a `dryRun` query parameter on a CONNECT request will now cause the request to be rejected, consistent with behavior of other mutating API requests. Examples of CONNECT APIs are the `nodes/proxy`, `services/proxy`, `pods/proxy`, `pods/exec`, and `pods/attach` subresources. Note that this prevents sending a `dryRun` parameter to backends via `{nodes,...

- APIService availability related to networking glitches are corrected faster ([#68678](https://github.com/kubernetes/kubernetes/pull/68678), [@deads2k](https://github.com/deads2k))

    * A distributed claim allows the OIDC provider to delegate a claim to a
    * separate URL.  Distributed claims are of the form as seen below, and are
    * defined in the OIDC Connect Core 1.0, section 5.6.2.
    * For details, see:
    * http://openid.net/specs/openid-connect-core-1_0.html#AggregatedDistributedClaims

* Update kube-dns to Version 1.14.8 that includes only small changes to how Prometheus metrics are collected. ([#57918](https://github.com/kubernetes/kubernetes/pull/57918), [@rramkumar1](https://github.com/rramkumar1))

- Fixes a bug where images pinned by the container runtime can be garbage collected by kubelet. ([#120053](https://github.com/kubernetes/kubernetes/pull/120053), [@ruiwen-zhao](https://github.com/ruiwen-zhao)) [SIG Node]

- Added a "reason" field to the "image_garbage_collected_total" metric, allowing administrators to differentiate between images that were collected for reasons "age" vs "space".

  - Published OpenAPI for the StatefulSet schema is corrected to indicate the `.spec.serviceName` is optional. ([#130233](https://github.com/kubernetes/kubernetes/pull/130233), [@soltysh](https://github.com/soltysh)) [SIG API Machinery, Apps and Testing]
