We have a number of Flink apps that are hosted as AWS Kinesis Data Analytics apps, and we want to upgrade them from Flink 1.6 to a more recent version (The more recent the better). Which version from this list is the best target for us if we want to avoid API changes that break our current code?

Hey Daniel, Flink claims to be backwards compatible but there are some deprecated APIs and breaking changes you might experience. Unfortunately the best course of action would be to test these version updates locally on an IDE and test that your apps still work before upgrading

Thanks Jeremy
