## 1. Overview

Persistent handles (also known as durable handles) allow SMB3 connections to survive network disconnections, server reboots, and client reconnections. This feature is critical for enterprise reliability and seamless failover scenarios.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13.2.3**: SMB2_CREATE_DURABLE_HANDLE_REQUEST
- **MS-SMB2 Section 2.2.13.2.4**: SMB2_CREATE_DURABLE_HANDLE_REQUEST_V2

### Node

SIG Node iterated on the ability to support more workloads with better performance and improved reliability.  Alpha features were improved around hardware accelerator support, device plugins enablement, and cpu pinning policies to enable us to graduate these features to beta in a future release.  In addition, a number of reliability and performance enhancements were made across the node to help operators in production.

### OpenStack

- Improved reboot event reporting. The kubelet will only emit one reboot Event when a server-level reboot 

    NVIDIA Ampere based GPUs and is enabled by default.

*   A major refactoring of the internals of the Keras Functional API has been
    completed, that should improve the reliability, stability, and performance
    of constructing Functional models.

*   Keras mixed precision API
    [`tf.keras.mixed_precision`](https://www.tensorflow.org/api_docs/python/tf/keras/mixed_precision?version=nightly)

- Fix job controller syncs: In case of conflicts, ensure that the sync happens with the most up to date information. Improves reliability of JobTrackingWithFinalizers. ([#105214](https://github.com/kubernetes/kubernetes/pull/105214), [@alculquicondor](https://github.com/alculquicondor))
