Time to Say Bye: ArcGIS API for JavaScript, Version 3.x is Retiring in July

[YixuanEmilyHu]

Officially announced February 2023, the 15-year-old legacy ArcGIS API 3.x for JavaScript will be retired on July 1st, 2024. Version 3.46 is the last 3.x version. We fully appreciate all the amazing works you created with the 3.x API over the years.

We strongly encourage you to build all new apps using the more powerful, performant, and modern 2D/3D ArcGIS Maps SDK for JavaScript and migrate 3.x-based apps.

Find more migration resources and FAQs at the retirement blog.

THANK YOU!
