### Other notable changes

* StatefulSet: Set hostname/subdomain fields on new Pods in addition to the deprecated annotations, to allow mitigation of Pod DNS issues upon upgrading to Kubernetes v1.7.x. ([#50942](https://github.com/kubernetes/kubernetes/pull/50942), [@enisoc](https://github.com/enisoc))
* Azure: Allow VNet to be in a separate Resource Group. ([#49725](https://github.com/kubernetes/kubernetes/pull/49725), [@sylr](https://github.com/sylr))

### Phase 2: Persistent Handles
**Priority: HIGH** | **Estimated Effort: 4-5 weeks**

Persistent handles allow connections to survive network interruptions and server failovers.

#### 2.1 Core Persistent Handle Infrastructure
```
Package: jcifs.internal.smb2.persistent

Go 1.25 added a new `embedfollowsymlinks` setting that controls whether the
Go command will follow symlinks to regular files embedding files.
The default value `embedfollowsymlinks=0` does not allow following
symlinks. `embedfollowsymlinks=1` will allow following symlinks.

Go 1.25 added a new `containermaxprocs` setting that controls whether the Go
runtime will consider cgroup CPU limits when setting the default GOMAXPROCS.
