https://js.arcgis.com/5.2.0-next/
This prerelease of the ArcGIS Maps SDK for JavaScript version 5.2 is intended for developers who want to evaluate upcoming features or test their applications before the November 2026 release.
This version is not recommended for production deployments.
Note
Beginning with version 5.0, the SDK uses semantic versioning. Prerelease CDN URLs now include the full version number (for example, 5.2.0-next) instead of next.
Some features available in next builds may be deferred and not appear in the final release. Report issues only if they are reproducible in a next or rc (release candidate) build and are not already present in the current production release. For all other questions about released versions we recommend posting on the Esri Community site.
For more information, see the Versioning and change management FAQ.
Read the release notes for the current production version of the SDK at https://developers.arcgis.com/javascript/latest/release-notes/.
Review the CHANGELOG.md to learn about new functionality, bug fixes and any breaking changes in the next version.
