* kubeadm - Increase the manifest upgrade timeout to make upgrades more reliable. ([#65029](https://github.com/kubernetes/kubernetes/pull/65029), [@detiber](https://github.com/detiber))

- Shared informers are now more reliable in the face of network disruption. ([#86015](https://github.com/kubernetes/kubernetes/pull/86015), [@squeed](https://github.com/squeed)) [SIG API Machinery]

        SmbFile verifySource = new SmbFile(baseUrl + "shared/" + sourceFileName, verifyContext);
        assertTrue(verifySource.exists(), "Source file should exist");

        // Perform rename using copy+delete as this is more reliable with Docker/Samba
        CIFSContext renameContext = createFreshContext();
        SmbFile srcForCopy = new SmbFile(baseUrl + "shared/" + sourceFileName, renameContext);

### SIG Multi-cluster (formerly known as SIG Federation)

[SIG Multi-cluster][] is responsible for infrastructure that supports
the efficient and reliable management of multiple Kubernetes clusters,
and applications that run in and across multiple clusters.

For the 1.8 release, SIG Multicluster focussed on expanding the set of

    *   reflector_short_watches_total
    *   reflector_watch_duration_seconds
    *   reflector_watches_total
    * While this is a backwards-incompatible change, it would have been impossible to setup reliable monitoring around these metrics since the labels were not stable. 

* Updates Cinder AttachDisk operation to be more reliable by delegating Detaches to volume manager. ([#50042](https://github.com/kubernetes/kubernetes/pull/50042), [@jingxu97](https://github.com/jingxu97))

* Fixed an issue where Portworx volume driver wasn't passing namespace and annotations to the Portworx Create API. ([#59607](https://github.com/kubernetes/kubernetes/pull/59607), [@harsh-px](https://github.com/harsh-px))
* Use a more reliable way to get total physical memory on windows nodes ([#57124](https://github.com/kubernetes/kubernetes/pull/57124), [@JiangtianLi](https://github.com/JiangtianLi))

    * kubeadm - Update generated etcd peer certificate to include localhost addresses for the default configuration.
    * kubeadm - Increase the manifest update timeout to make upgrades a bit more reliable.
* Kubernetes depends on v0.30.1 of cAdvisor ([#64987](https://github.com/kubernetes/kubernetes/pull/64987), [@dashpole](https://github.com/dashpole))

#### Continuous Improvement
- Project sustainability is not just about features. Many SIGs have been working on  improving test coverage, ensuring the basics stay reliable, and stability of the core feature set and working on maturing existing features and cleaning up the backlog.
