Sourced from arrow's releases.

arrow 59.1.0

Changelog

59.1.0 (2026-07-03)

Full Changelog

Implemented enhancements:

• Fast path for nested DictionaryArray casting #10247 [arrow]
• parquet/arrow: reading multiple nested columns fails with "Not all children array length are the same!" when a list continues across DataPageV2 page boundary #10243 [parquet]
• Add product aggregate kernel to arrow-rs #10150 [arrow]
• Stricter DataType parsing #10146 [arrow]
• Support validating CSV headers against Schema #10143 [arrow]
• arrow-ipc: Supports compression level configuration for arrow-ipc writer #10132 [arrow]
• [Variant] VariantArray field API naming #10093
• Add StructArray::field_ APIs symmetric to StructArray::column_ ones #10092 [arrow]
• arrow-buffer: implement Saturating, CheckedShl, Not num-traits for i256 #10087 [arrow]
• feat: native concat for MapArray #10047 [arrow]
• [Variant] Add variant_to_arrow Dictionary/REE type support #10013

Fixed bugs:

• arrow-row on fixed size binary/list with size 0 and no nulls return wrong length #10270
• casting list to 0-size fixedsizelist can cause incorrect output length #10227 [arrow]
• Buffer count mismatched with metadata when encoding records with dictionary of dictionaries #10213 [arrow]
• Buffer::into_mutable is not consistent regarding sliced data and can lead to panics #10117 [arrow]
• parquet_derive: cannot read or write columns whose name is a Rust keyword (raw identifiers like r#type become column "r#type") #10112
• parquet: fix OffsetBuffer panic on corrupt input #10107 [parquet]
• Parquet geospatial conversion uses metadata key "algorithm" instead of "edges" in geoarrow metadata #9929 [parquet]
