ArcGIS API for JavaScript - old versions

[PitersonPaulgek]

Hi,

We are not able to find how much time old versions of ArcGIS API for JavaScript are supported.

Is there any link or whatever from ESRI?

Any help please.

Robert,

Thank you for your response.

So, what is time 3.17 support will end?
