Migrating from JavaScript 4.10 to 4.23 tips

[TimDietz]

We have an existing application that has been pointing to the 4.10 version of ArcGIS JavaScript API.  To add additional functionality, we have found that we can update to V4.23 with minimal updates.  Problem is, we don't really know what some of the upgrade "must do's" are.

Things like esri/tasks/support/Query is now esri/rest/support/Query (as of V4.20).

Is there a place where I can find all of the release notes for each update to see what I need to change in my app?

TIA

There's not one page to do that, but you can use the url https://developers.arcgis.com/javascript/latest/4.xx/ (replacing xx with your version number) to go through the Release notes for each version

Looks like ESRI hid the old versions in the sidebar on the documentation site, but the links to the older versions are still available at the bottom of the page.

Hi @TimDietz -

I would suggest reviewing the breaking changes page: https://developers.arcgis.com/javascript/latest/breaking-changes/ 

It is a curated list of breaking changes from each release and matches what is on the release notes.

Hope that helps!
