## Compatibility notes
* Python 3.15 is supported and wheels created
[GH-48172](https://github.com/apache/arrow/issues/48172).
* Python 3.10 support dropped
[GH-50410](https://github.com/apache/arrow/issues/50410).
* Support for pandas < 2.0.0 dropped
[GH-48808](https://github.com/apache/arrow/issues/48808).
* We now require numpy 2.x
[GH-48473](https://github.com/apache/arrow/issues/48473).
## New features
* Conversion from numpy `StringDtype` to Arrow `string` (also `large_string`
or `string_view`) is added
[GH-51652](https://github.com/apache/arrow/issues/51652).
* DLPack implementation is now complete with the ability for Arrow Arrays,
Tensors [GH-39295](https://github.com/apache/arrow/issues/39295) and
`FixedShapeTensorArray`/`FixedShapeTensorScalar`
[GH-38868](https://github.com/apache/arrow/issues/38868) to consume objects
implementing this protocol. Also the protocol version has been updated to use
version 1.3 [GH-41670](https://github.com/apache/arrow/issues/41670).
* `record_batch_reader_source` Acero node
(`RecordBatchReaderSourceNodeOptions`) is exposed
[GH-50801](https://github.com/apache/arrow/issues/50801).
* `search_sorted` kernel for all primitive types and run-end encoded arrays
is available [GH-49677](https://github.com/apache/arrow/issues/49677).
* `RecordBatchFileReader.count_rows()` binding is added
[GH-49305](https://github.com/apache/arrow/issues/49305).
* ` List`, `ListView`, `LargeList`, `LargeListView`, `Map`, `FixedSizeList`
and `Struct` values are supported in the `run_end_encode` and the
`run_end_decode` paths [GH-44183](https://github.com/apache/arrow/issues/44183).
* `eol` and `null_string` csv `WriteOptions` have been exposed
[GH-34577](https://github.com/apache/arrow/issues/34577).
## Other improvements
* `.slice` methods accept Arrow intger scalars
[GH-51145](https://github.com/apache/arrow/issues/51145).
* `arrow_to_pandas` `DateOffset` handling for nanoseconds/milliseconds is
simplified [GH-50464](https://github.com/apache/arrow/issues/50464).
* First step towards abi3 wheels support for pyarrow has been merged
[GH-50431](https://github.com/apache/arrow/issues/50431).
* `is_nested` now uses C++ type traits
[GH-40282](https://github.com/apache/arrow/issues/40282).
## Relevant bug fixes
* UUID extension type round-trip to pandas returning bytes is
fixed[GH-50312](https://github.com/apache/arrow/issues/50312).
* Scalar arithmetic dunders now return `NotImplemented` instead of raising
`TypeError` when the other operand is not a recognized Arrow/NumPy type
[GH-49826](https://github.com/apache/arrow/issues/49826).
* Raise instead of crashing on unopened `MemoryMappedFile().resize()`
[GH-51229](https://github.com/apache/arrow/issues/51229).
* Writer options are synced between `write_table` and
`write_to_dataset`/`ParquetFileFormat.make_write_options(...)`
[GH-51220](https://github.com/apache/arrow/issues/51220).
* `BufferReader.readinto()` segfaults on a read-only destination are fixed
[GH-51044](https://github.com/apache/arrow/issues/51044).
* `FunctionOptions.deserialize()` segfaults on non-buffer arguments are
fixed [GH-51041](https://github.com/apache/arrow/issues/51041).
* Correct type of `ParquetLogicalType` is now returned for
Geometry/Geography [GH-50849](https://github.com/apache/arrow/issues/50849).
* `pa.types.is_nested()` now returns `True` for run-end encoded types
[GH-50847](https://github.com/apache/arrow/issues/50847).
* The reference cycle between the C++ FlightServerBase and the Python object
now breaks to avoid leaking server
[GH-50684](https://github.com/apache/arrow/issues/50684).
