December 2025 - ytsaurus/ytsaurus: Key reliability and safety improvements. Delivered Late Data Partition Handling in the Flow Controller to better handle out-of-order data (commit 7bcf2c476e3421e7ec936b117ecb1ceae7565b9a). Fixed a use-after-free in the topological ordering path to boost memory safety and stability (commit bb2cbcbcab7434ec0f633fb46e9d9a53533c89b4). These changes enhance data processing resilience, reduce crashes, and support more reliable streaming pipelines.
