Wow, there seems to be a lot of impressive new features!

Key changes: ~60% faster execution (joins & aggregations), full Apache Iceberg support (hidden partitions, compaction API, optimized metadata), enhanced JSON handling with Flat JSON V2, major reductions in cloud-storage API usage through file bundling and metadata caching, plus SQL-level improvements such as Decimal256 and ASOF JOIN.

The focus: stronger performance, better open-format support, and more enterprise-friendly governance.
