This allows `iceberg-rust` users to add, drop, rename, and update columns through a builder interface. + +### Snapshot Expiration + +A new [`ExpireSnapshotsAction`](https://github.com/apache/iceberg-rust/pull/2591) provides a high-level API for expiring old snapshots, respecting `history.expire.*` table properties and cleaning up associated statistics file metadata for the expired snapshots. + +### Custom Runtime Support + +The [`Runtime` trait](https://github.com/apache/iceberg-rust/pull/2308) can now be injected into catalogs, decoupling `iceberg-rust` from a hard tokio dependency at the catalog layer. This enables embedding in applications with custom async runtimes. + +### Writer Improvements + +- **[Table property-driven Parquet settings](https://github.com/apache/iceberg-rust/pull/2561)**: `ParquetWriterBuilder::from_table_properties` now honors `write.parquet.*` table properties, eliminating the need for manual configuration +- **[Content-defined chunking](https://github.com/apache/iceberg-rust/pull/2375)**: CDC table properties for optimizing Parquet file boundaries +- **[Purge table support](https://github.com/apache/iceberg-rust/pull/2232)**: Catalogs can now purge tables, deleting both metadata and data files + +### Enhanced DataFusion Integration + +- **[EXPLAIN shows pushed-down limits](https://github.com/apache/iceberg-rust/pull/2360)**: `IcebergTableScan` now displays limit pushdown in EXPLAIN output for query debugging +- **[IsNaN predicate pushdown](https://github.com/apache/iceberg-rust/pull/2592)**: NaN-preserving numeric expressions are now pushed into scans +- **[Empty insert handling](https://github.com/apache/iceberg-rust/pull/2712)**: INSERT operations that produce no rows now correctly return a single row with count 0 + +### Reader and Scan Improvements + +- **[Scan I/O metrics](https://github.com/apache/iceberg-rust/pull/2349)**: New `read_with_metrics()` API exposes bytes read and other I/O statistics during scans +- **[Name-mapped field IDs](https://github.com/apache/iceberg-rust/pull/2612)**: Projection and predicate pushdown now correctly use name-mapped field IDs for tables without embedded field IDs +- **[FixedBinary(N) support](https://github.com/apache/iceberg-rust/pull/2348)**: Added support for fixed-length binary types +- **[Snappy codec for Avro](https://github.com/apache/iceberg-rust/pull/2573)**: Avro files compressed with Snappy can now be read + +### Table Encryption (Foundational) + +Significant groundwork has been laid toward Iceberg's table encryption specification, including [AES-GCM cryptographic primitives](https://github.com/apache/iceberg-rust/pull/2026), [streaming encryption/decryption](https://github.com/apache/iceberg-rust/pull/2286), a [KMS trait](https://github.com/apache/iceberg-rust/pull/2339), [StandardKeyMetadata](https://github.com/apache/iceberg-rust/pull/2340), an [Encryption Manager](https://github.com/apache/iceberg-rust/pull/2383), and [manifest-list-level decryption plumbing](https://github.com/apache/iceberg-rust/pull/2453). Writes to encrypted tables are [explicitly blocked](https://github.com/apache/iceberg-rust/pull/2626) until the full write path is complete. End-to-end read and write support for encrypted tables is expected in a future release. See the [table encryption RFC](https://github.com/apache/iceberg-rust/pull/2183) for the full design. + +### Storage Improvements + +#### New Storage Backend - HuggingFace Hub + +A new [HuggingFace Hub storage backend](https://github.com/apache/iceberg-rust/pull/2375) was contributed, enabling direct access to Iceberg tables hosted on HuggingFace datasets. + +#### Other improvements + +- **[`delete_stream` on Storage trait](https://github.com/apache/iceberg-rust/pull/2216)**: Batch delete operations for efficient cleanup +- **[OpenDAL resolving storage](https://github.com/apache/iceberg-rust/pull/2231)**: Automatically resolves the appropriate storage backend based on file path scheme +- **[Timeout layer for OpenDAL](https://github.com/apache/iceberg-rust/pull/2455)**: Added `TimeoutLayer` inside `RetryLayer` to prevent indefinite hangs +- **[S3 virtual-host-style addressing](https://github.com/apache/iceberg-rust/pull/2330)**: Default to virtual-host-style S3 addressing for broader compatibility + +## Bug Fixes Review Comment: https://github.com/apache/iceberg-rust/pull/2351 was a correctness issue also if you wanted to include that? -- This is an automated message from the Apache Git Service.
