Starting October 15, ensure to use Platform version 2.2 and FDK 7 (Node.js 12) when building new apps or updating your existing apps. Support for building, updating, or publishing apps by using earlier platform/FDK versions will be deprecated.
This will not affect existing apps. Support for apps that are built using earlier Platform/FDK versions and already published on the Marketplace will continue until further notice.
In the interim, we strongly recommend migrating your published apps to Platform version 2.2 using FDK 7 (Node.js 12). For migration instructions, see migrating Platform version to 2.2 and migrating apps from FDK 6 to FDK 7.
