Thanks your feedback and suggestions. Regarding StreamPark's support for multiple versions of Flink, due to the uniqueness of our architecture design, we have never bound the code to a specific version of Flink's API, making it very easy for us to support a new version. Therefore, we can support all versions of Flink after 1.12. Currently, due to the large number of users using Flink 1.12 to 1.14, and considering the above two reasons, we will continue to adopt this strategy in StreamPark's current versions(2.1.2, 2.2.0), which default to supporting and retaining all versions of Flink after 1.12. However, as more and more versions of Flink are released, StreamPark will only keeps the last three flink versions. BTW, In version 2.2.0, we have already discontinued support for Scala 2.11. This is a gradual process, and we plan to implement this plan in the next major version such as 2.3.0.
