    * In order to safely upgrade an existing Kubernetes cluster without interruption of volume attach/detach logic:
        * First upgrade the master to Kubernetes v1.3.
            * This will start the new attach/detach controller.

- Fixed `vSphere` cloud provider not to skip detach volumes from nodes at `kube-controller-startup`. ([#117243](https://github.com/kubernetes/kubernetes/pull/117243), [@jsafrane](https://github.com/jsafrane))

- `kubelet` now emits a metric for end-to-end pod startup latency, including image pull. ([#121041](https://github.com/kubernetes/kubernetes/pull/121041), [@ruiwen-zhao](https://github.com/ruiwen-zhao))
- `kubelet` now exposes latency metrics of different stages of the node startup. ([#118568](https://github.com/kubernetes/kubernetes/pull/118568), [@qiutongs](https://github.com/qiutongs))

- Fixed a startup probe race condition that caused main containers to remain stuck in "Initializing" state when sidecar containers with startup probes failed initially but succeeded on restart in pods with restartPolicy=Never. ([#134800](https://github.com/kubernetes/kubernetes/pull/134800), [@yuanwang04](https://github.com/yuanwang04))...

- Fixed a regression in default 1.29 configurations with the `SidecarContainers` feature enabled, where init containers may fail to start due to a temporary container runtime failure. ([#126543](https://github.com/kubernetes/kubernetes/pull/126543),...

- Node affinity, Node selectors, and tolerations are now mutable for Jobs that are suspended and have never been started ([#105479](https://github.com/kubernetes/kubernetes/pull/105479), [@ahg-g](https://github.com/ahg-g))
- Pod template annotations and labels are now mutable for Jobs that are suspended and have never been started ([#105980](https://github.com/kubernetes/kubernetes/pull/105980), [@ahg-g](https://github.com/ahg-g))

- Fixed a bug that the kubelet cannot start on BtrfS. ([#98042](https://github.com/kubernetes/kubernetes/pull/98042), [@gjkim42](https://github.com/gjkim42)) [SIG Node]
