### Search before asking - [x] I have searched in the [issues](https://github.com/apache/amoro/issues?q=is%3Aissue) and found no similar issues. ### What would you like to be improved? Amoro mixed-format Flink currently maintains version-specific modules for Flink 1.18 and 1.19, but does not yet provide a Flink 1.20 variant. Flink 1.20 is the last minor release of the 1.x line (LTS), and Iceberg's multi-engine support matrix maintains it: `iceberg-flink-1.20` is published for the Iceberg 1.7 line we currently depend on, and continues to be published through the latest Iceberg releases. Adding a Flink 1.20 variant keeps Amoro's mixed-format Flink support aligned with the engine versions Iceberg maintains, and reduces friction for future Iceberg upgrades. With this addition the mixed-format Flink support matrix becomes 1.18 / 1.19 / 1.20, which matches the usual three-version policy, so no version needs to be dropped. ### How should we improve? We should add mixed Flink 1.20 support to Amoro. This likely includes: - adding `v1.20/amoro-mixed-flink-1.20` - adding `v1.20/amoro-mixed-flink-runtime-1.20` - updating parent module definitions - validating catalog, source/sink, and runtime compatibility under Flink 1.20 - updating documentation for the supported Flink version matrix ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Subtasks - [ ] Add mixed Flink 1.20 modules - [ ] Verify compile/tests for Flink 1.20 - [ ] Update related documentation ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
