+
+[changelog]:
https://github.com/apache/iceberg-rust/blob/main/CHANGELOG.md#v080---2026-01-06
+
+`iceberg-rust` is a native Rust implementation of the Apache Iceberg
specification, providing high-performance libraries for reading, writing, and
managing Iceberg tables in Rust applications and through Python bindings
(`pyiceberg-core`).
+
+<!-- more -->
+
+## Release Highlights
+
+### V3 Metadata Support
+
+This release introduces [support for Iceberg V3 metadata
format](https://github.com/apache/iceberg-rust/pull/1682), enabling
`iceberg-rust` to work with the latest version of the Iceberg table
specification. This includes support for V3 manifests with delete file content
and enhanced metadata handling.
+
+### Enhanced DataFusion Integration
+
+The DataFusion integration received significant improvements:
+
+- **INSERT INTO partitioned tables**: [Native
support](https://github.com/apache/iceberg-rust/pull/1827) for inserting data
into partitioned Iceberg tables, with [partition column
projection](https://github.com/apache/iceberg-rust/pull/1602) and
[repartitioning operator](https://github.com/apache/iceberg-rust/pull/1620)
+- **Partition-aware sorting**: [New `sort_by_partition`
operator](https://github.com/apache/iceberg-rust/pull/1618) to sort input data
by partition values
+- **SQLLogicTest integration**: [Added comprehensive testing
framework](https://github.com/apache/iceberg-rust/pull/1764) for DataFusion
operations
+- **Parallel writing**: [Implemented parallel writer
interface](https://github.com/apache/iceberg-rust/pull/1769) for DataFusion
execution
+
+### Advanced Delete File Handling
+
+`iceberg-rust` now has substantially improved support for Iceberg's delete
files:
+
+- **Shared delete file caching**: [Optimized
performance](https://github.com/apache/iceberg-rust/pull/1941) by caching and
sharing delete files across multiple readers
+- **Mixed delete types**: [Support for both position and equality
deletes](https://github.com/apache/iceberg-rust/pull/1778) on the same
FileScanTask
+- **Binary type support**: [Added binary type
support](https://github.com/apache/iceberg-rust/pull/1848) in equality delete
processing
+- **Performance fixes**: Fixed [stack overflow with large
deletes](https://github.com/apache/iceberg-rust/pull/1915) and [scan
deadlocks](https://github.com/apache/iceberg-rust/pull/1937)
+- **Row group filtering**: [Improved
filtering](https://github.com/apache/iceberg-rust/pull/1779) when FileScanTask
contains byte ranges
+- **Case-sensitive deletes**: [Added
support](https://github.com/apache/iceberg-rust/pull/1930) for case-sensitive
equality delete matching
+
+### Enhanced Reader Capabilities
+
+The Arrow reader received several important enhancements:
+
+- **Position-based projection**: [Support for Parquet files without field
IDs](https://github.com/apache/iceberg-rust/pull/1777), enabling reads from
migrated tables
+- **PartitionSpec support**: [Added partition
awareness](https://github.com/apache/iceberg-rust/pull/1821) to FileScanTask
and RecordBatchTransformer
+- **Schema evolution**: [Fixed
handling](https://github.com/apache/iceberg-rust/pull/1750) of Parquet files
with schema changes
+- **Compressed metadata**: [Support for
reading](https://github.com/apache/iceberg-rust/pull/1802) compressed table
metadata
+- **Date32 support**: Improved handling of [Date32
values](https://github.com/apache/iceberg-rust/pull/1792) and [struct
defaults](https://github.com/apache/iceberg-rust/pull/1847)
+- **Binary deserialization**: [Added
support](https://github.com/apache/iceberg-rust/pull/1820) for deserializing
bytes values
+- **`_file` metadata column**: [Support for Iceberg's `_file`
column](https://github.com/apache/iceberg-rust/pull/1824) to expose source file
information
+
+### Advanced Writers
+
+New writer implementations provide flexible approaches to data organization:
+
+- **Clustered and Fanout writers**: [Implemented
writers](https://github.com/apache/iceberg-rust/pull/1735) for different data
distribution strategies
+- **Configurable FanoutWriter**: [Made writer
configuration](https://github.com/apache/iceberg-rust/pull/1962) more flexible
+- **Non-consuming builders**: [Refactored writer
builders](https://github.com/apache/iceberg-rust/pull/1889) to not consume
self, allowing reuse
+
+### Catalog Improvements
+
+Multiple catalog implementations received updates:
+
+- **SqlCatalog**: Added [update_table
support](https://github.com/apache/iceberg-rust/pull/1911),
[register_table](https://github.com/apache/iceberg-rust/pull/1724), and a
[builder pattern](https://github.com/apache/iceberg-rust/pull/1666)
+- **S3TablesCatalog**: [Implemented
update_table](https://github.com/apache/iceberg-rust/pull/1594) for AWS S3
Tables
+- **Glue**: [Improved concurrency error
handling](https://github.com/apache/iceberg-rust/pull/1875) for Glue catalog
+- **MemoryCatalog**: [Fixed namespace
handling](https://github.com/apache/iceberg-rust/pull/1970) to return absolute
NamespaceIdents
+- **REST catalog**: [Improved
authentication](https://github.com/apache/iceberg-rust/pull/1712) and [made
types public](https://github.com/apache/iceberg-rust/pull/1901) with
documentation
+
+### Schema Conversion
+
+[New capability](https://github.com/apache/iceberg-rust/pull/1928) to convert
Arrow schemas to Iceberg schemas with auto-assigned field IDs, simplifying
integration with Arrow-based systems.
+
+### PyIceberg-core Improvements
+
+The Python bindings received multiple enhancements:
+
+- **Smaller artifacts**: Multiple optimizations
([#1841](https://github.com/apache/iceberg-rust/pull/1841),
[#1844](https://github.com/apache/iceberg-rust/pull/1844)) reduced package size
+- **ABI3 support**: [Using pyo3
abi3-py310](https://github.com/apache/iceberg-rust/pull/1843) for better Python
version compatibility
+- **RecordBatchTransformerBuilder**: [Updated
API](https://github.com/apache/iceberg-rust/pull/1857) for more ergonomic usage
