Overview

As Sitecore advances its composable and agentic platform vision, the Content SDK is now the official and supported SDK for Sitecore XM Cloud.

The Content SDK is the new version of the JSS framework designed specifically for XM Cloud, and as support ends for the supported JSS versions, customers will follow the simple upgrade process to move to the new framework.

This article outlines the lifecycle stages for SDKs used with XM Cloud, helping developers and customers plan their migration and ensure continued support.

SDK lifecycle summary for XM Cloud

Notes:

• JSS SDK 23.X is expected to be released around March/April 2026. This JSS Version fully supports our DXP like XM/XP, but it will not be supported for XM Cloud.
• Content SDK 1.X is the current active version for XM Cloud. As Sitecore has not yet released another major version, there is no expiration date for its support. It remains in Active and LTS support until a new major version has been released.
