+
+The Apache Arrow team is pleased to announce that the v60.0.0 release of
Apache Arrow
+Rust is now available on crates.io ([arrow] and [parquet]) and as [source
download].

+[arrow]: https://crates.io/crates/arrow
+[parquet]: https://crates.io/crates/parquet
+[source download]:
https://dist.apache.org/repos/dist/release/arrow/arrow-rs-60.0.0
+
+See the [60.0.0 changelog] for a full list of changes.
+
+[60.0.0 changelog]: https://github.com/apache/arrow-rs/blob/60.0.0/CHANGELOG.md
+
+## Highlights
+
+This release includes new Parquet encoding support, a sustained effort to
remove
+panics from the codebase, a large number of kernel performance improvements,
and
+many bug fixes across decimals, take/filter, and FFI.
+
+MSRV is bumped to 1.88,
+`rand` upgraded to 0.10, `object_store` to 0.14.1, and several long-deprecated
+items have been removed. See the [60.0.0 changelog] for the full breaking
+changes list.
+
+## New Features
+
+### Parquet ALP Encoder/Decoder Support
+
+[@sdf-jkl] added support for the [Adaptive Lossless Floating-Point (ALP)]
+encoding in Parquet ([#9372]). ALP is a high-performance encoding for
+floating-point columns that enables compact storage, fast decoding and single
value random-access.
+This makes arrow-rs the first Parquet implementations to support ALP,
+keeping the [parquet] crate aligned with the latest Parquet specification.
+
+[Adaptive Lossless Floating-Point (ALP)]:

+[@sdf-jkl]: https://github.com/sdf-jkl
+[#9372]: https://github.com/apache/arrow-rs/pull/9372
+
+### Parquet Page Index Improvements
+
+[@etseidl] made several improvements to Parquet page index handling: a new
+[`PageIndex`] struct encapsulating column and offset indexes ([#10719]), new
+[`PageIndexBuilder`] and [`PageIndexProvider`] types ([#10842]), and page index
+decoders are now public ([#10899]). One major use case enabled by these
+changes is supplying external or cached `PageIndex`es directly to the reader
+(for example, indexes previously fetched and stored outside the file),
+avoiding redundant I/O on repeated scans. This also opens the door for
+selective population of the page indexes which will help reduce the latency
+of filtered scans against very wide tables.

+
+### Parquet NDV Statistics, FILE Logical Type, and IEEE 754 Total Order
+
+[@Rich-T-kid] implemented writing num distinct values (NDV) statistics in the
+Parquet writer ([#10654]) and added row-group-level distinct counts to
+`StatisticsConverter` ([#10652]). Query engines use these to make better
+planning decisions such as join strategy selection and filter selectivity
+estimates.
+
+[@brkyvz] added support for the `FILE` logical type ([#10109]). [@etseidl]
+implemented [PARQUET-2249] IEEE 754 total order for floating-point comparisons
+([#9619]) and the corresponding `INT96` timestamp `ColumnOrder` ([#10106]).
+[@etseidl] also removed the previous limit of 32,768 row groups per file
+([#10149]).

+
+### New `arrow-cmp` Crate
+
+[@Rich-T-kid] introduced the [`arrow-cmp`] crate ([#10325]), splitting
+comparison kernel logic out of [`arrow-ord`] into its own focused crate. This
+gives users a more targeted dependency for Arrow comparison operations without
+pulling in the broader `arrow-ord` crate.

+
+## Panic Elimination
+
+A lot of work went into converting panics into proper `Result` returns this
+release. [@emilk] fixed `try_` functions still panicking in edge cases
([#10730],
+[#10755]) and removed panics from `GenericByteArray::from_iter_values`
([#10729]).
+[@bit2swaz] replaced panics with errors in IPC schema and footer parsing
+([#10647], [#10744]) and closed an FFI `Drop` soundness hole ([#10431]).
+[@Rich-T-kid] fixed a potential use-after-free in `Buffer::shrink_to_fit`
([#10932])
+and converted `MutableBuffer` panicking callsites to fallible methods
([#10641],
+[#10317]). [@okhsunrog] made `interleave`/`concat` return errors on dictionary
key
+overflow ([#10675]). [@ranflarion] converted a Parquet buffer push panic into
an
+error ([#10564]) and [@dhruvxvaishnav] did the same for invalid dictionary
index
+bit widths ([#10725]).

+
+## Performance Improvements
+
+This release has a large number of performance improvements across kernels,
+casting, and Parquet I/O.
+
+### Take/Filter Kernel Improvements
+
+[@Rich-T-kid] landed a series of take/filter kernel speedups this release:
+`take` on `FixedSizeList` is up to **3.3x faster** ([#10441]), `take` on
+`List<T>` up to **1.8x faster** ([#10812]), `take` on boolean and null buffers
+up to **1.7x faster** ([#10813]), and `filter` on `FixedSizeBinary` up to
+**1.4x faster** ([#10993]). A `NullBuffer::expand` rewrite for aligned counts
+delivers up to **143x faster** buffer expansion ([#10976], [#10980]).
+
+[@YUZHEthefool] improved `rank` on `StringViewArray` by up to **3.2x faster**
+via prefix key caching ([#10605]). [@giladkl] made equality/inequality
+comparisons of byte-view arrays against short scalars up to **2.5x faster**
+([#10689]). [@cakeni] replaced `BufferBuilder` with `Vec` across
+`concat_elements`, `take_run`, `substring`, and other kernels
+([#10629]-[#10634]), and [@kowanietz] did the same for primitive unary
+operations ([#10783]) and fixed-size binary take ([#10773]), cutting
+unnecessary allocations across the board. [@haohuaijin] fixed in-place
+bitwise ops corrupting bits outside the requested range ([#10444]).
+
+### Decimal Casting
+
+[@neilconway] made decimal parsing dramatically faster across the board. A
+foundational rewrite of the decimal-from-string path ([#10668]) alone delivers
+**up to ~8x faster** casting from strings to `Decimal128` and up to **92%
lower parsing time**
+on individual parse microbenchmarks. A follow-up pass for separate
+integer/fractional digit scanning ([#10974]) added another **5–15%** on top,
+and skipping redundant precision checks ([#10998]) added up to **~10%** more.
+Formatting `i256` without `num-bigint` ([#11000]) rounds things out with
+**~1.8x faster** `Decimal256` formatting for typical 38-digit values.
+
+### Parquet Reading Improvements
+
+Plain Parquet string column reads into dictionary arrays are **~1.5x faster**
+([#10614]). [@adriangb] sped up `DELTA_BYTE_ARRAY` shared-prefix decoding by
+scanning a block at a time ([#10549]), reaching **up to 19x faster** on the
+prefix-scan microbenchmark and **4.2x faster** end-to-end for small
+shared-prefix strings. [@haohuaijin] removed redundant copies in Parquet
+mask-backed intersection/union ([#10446]), delivering **2–6x faster** mask
+operations depending on alignment. [@hhhizzz] fixed cached Mask reads crossing
+unloaded sparse pages ([#10735]).
+
+### Binary Size Reduction
+
+[@alamb] reduced binary size by about **2%** by monomorphizing `PrimitiveArray`
+to `ArrayData` conversion and `Debug` formatting helpers ([#10893], [#10890]) —
+the Debug change alone cut **~12% of LLVM IR** from the `cast_kernels` binary.

+
+## Bug Fixes
+
+[@neilconway] fixed a cluster of decimal bugs including incorrect `Decimal256`
+casting to signed integers ([#10857]), wrong min/max statistics for
`BYTE_ARRAY`
+decimals ([#10861]), mismatched scales in `make_comparator` ([#10864]),
+formatting bugs ([#10869]), and a spurious assert when `scale == precision`
+([#10875]).
+
+[@yongster] fixed `take` for null indices in dense union and run-end encoded
+arrays ([#10909]).
+
+[@1fanwang] and [@tpoterba] fixed `take` and `interleave` on zero-width
+`FixedSizeListArray` ([#10915], [#11026]).
+
+[@jaideeppyne] fixed struct `ArrayData` slicing double-counting the offset
+([#10835], [#10934]). [@linhongyu510] fixed struct null validation not
+accounting for parent offsets ([#10970]).
+
+[@PlenoraETL] made the IPC reader return an error for a `DictionaryBatch`
+missing its data instead of silently producing wrong results ([#11020]).
+[@bit2swaz] made `FFI_ArrowSchema::with_metadata` `unsafe` to close a
+soundness gap ([#10764]).
+
+[@adriangb] fixed `DELTA_BYTE_ARRAY` deduplication for values larger than
+the page size limit ([#10505]).

+## Other Notable Changes
+
+- [@adamreeve] added round-trip support for `Dictionary(_,
Utf8View/BinaryView)`
+ columns in Parquet ([#10831])
+- [@ranflarion] improved Parquet bloom filters: populate from the dictionary
+ while a column is dictionary encoded ([#10966]) and added a writer option to
+ skip bloom filters for all-dictionary column chunks ([#10963])
+- [@haohuaijin] added row-group-local `RowSelection` support to the push
+ decoder ([#10702])
+- [@1fanwang] added `Utf8View` and `BinaryView` support to `substring`
([#10672])
+- [@etseidl] removed previously deprecated Parquet functions ([#10565]) and
+ deprecated `ColumnOrder::sort_order_for_type` ([#10104]) as a follow-up to
+ the INT96/IEEE 754 correctness work — both are breaking changes users will
+ notice at compile time.
