Flink 2.3.0 brings together contributors from around the globe, implements 15 FLIPs (Flink Improvement Proposals), and resolves numerous issues and enhancements. + +Key improvements in this release include new SQL operators for changelog manipulation (`FROM_CHANGELOG` and `TO_CHANGELOG`), fine-grained control over materialized table refresh strategies, adaptive partition selection for optimized backpressure handling, and a completely redesigned S3 filesystem built on AWS SDK v2. The introduction of application-level lifecycle management provides better visibility and control for production deployments, while enhanced watermark alignment can dramatically improve backlog processing performance. A reworked SinkUpsertMaterializer brings much improved performance for some Flink SQL workloads. + +We extend our heartfelt thanks to all contributors for making this release possible! + +Let's dive into the details. + +# Flink SQL Improvements + +## FROM_CHANGELOG and TO_CHANGELOG: Bridging Append-only and Dynamic Changelog Tables (FLIP-564) Review Comment: Done -- This is an automated message from the Apache Git Service.
