ArcGIS JS API 3.x CDN Lifetime

[Muhammad_AzhaziqBin_Mohd_Azlan]

Hi,

I have returning client that currently run a web application using ArcGIS JS API 3.x and it directly referencing 3.x API using CDN.

Anyone knows how long the 3.x library will be available via CDN?

ArcGIS API for JavaScript, Version 3.x Retirement

ArcGIS API 3.x for JavaScript was retired on July 1, 2024.
...

After retirement, the 3.x API will remain hosted on our CDN for a multi-year grace period

Your guess on how long a "multi-year grace period" actually is. I would say two years is probably the shortest time. For safety, you should probably plan to migrate from 3.x in 2026.

Ok. I did discuss with my colleague and we also guessing "multi-year grace period" meant. But certainly, we need to plan for the migration in 2026.
