## Overview

# Persistent Handles Feature - Detailed Design Document

## 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.

# Witness Protocol Feature - Detailed Design Document

## 1. Overview

The SMB Witness Protocol enables rapid notification of resource changes in a clustered file server environment. It provides fast failover capabilities by allowing clients to register for notifications about server node availability, share movement, and other critical cluster events.

 *  Fix: Don't crash on Java 8u252 which introduces an API previously found only on Java 9 and
    above. See [Jetty's overview][jetty_8_252] of the API change and its consequences.

## Version 3.14.7

_2020-02-24_

 *  Fix: Don't crash on Android 11 due to use of restricted methods. This prevents a crash with the

# Multi-Channel Feature - Detailed Design Document

## 1. Overview

SMB3 Multi-Channel enables the use of multiple network connections between client and server, providing increased throughput, network fault tolerance, and automatic failover capabilities. This feature aggregates bandwidth across multiple NICs and provides seamless failover when network paths fail.

 *  New: `MultipartReader` is a streaming decoder for [MIME multipart (RFC 2045)][rfc_2045]
    messages. It complements `MultipartBody` which is our streaming encoder.
