+<p>The Apache Arrow team is pleased to announce that the v60.0.0 release of
Apache Arrow
+Rust is now available on crates.io (<a href="https://crates.io/crates/arrow";
target="_blank" rel="noopener">arrow</a> and <a
href="https://crates.io/crates/parquet"; target="_blank"
rel="noopener">parquet</a>) and as <a
href="https://dist.apache.org/repos/dist/release/arrow/arrow-rs-60.0.0";
target="_blank" rel="noopener">source download</a>.</p>
+<p>See the <a
href="https://github.com/apache/arrow-rs/blob/60.0.0/CHANGELOG.md";
target="_blank" rel="noopener">60.0.0 changelog</a> for a full list of
changes.</p>
+<h2>Highlights</h2>
+<p>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.</p>
+<p>MSRV is bumped to 1.88,
+<code>rand</code> upgraded to 0.10, <code>object_store</code> to 0.14.1, and
several long-deprecated
+items have been removed. See the <a
href="https://github.com/apache/arrow-rs/blob/60.0.0/CHANGELOG.md";
target="_blank" rel="noopener">60.0.0 changelog</a> for the full breaking
+changes list.</p>
+<h2>New Features</h2>
+<h3>Parquet ALP Encoder/Decoder Support</h3>
+<p><a href="https://github.com/sdf-jkl"; target="_blank"
rel="noopener">@sdf-jkl</a> added support for the <a
href="https://parquet.apache.org/blog/2026/09/22/alp-adaptive-lossless-floating-point-encoding-in-apache-parquet/";
target="_blank" rel="noopener">Adaptive Lossless Floating-Point (ALP)</a>
+encoding in Parquet (<a href="https://github.com/apache/arrow-rs/pull/9372";
target="_blank" rel="noopener">#9372</a>). 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 <a href="https://crates.io/crates/parquet"; target="_blank"
rel="noopener">parquet</a> crate aligned with the latest Parquet
specification.</p>
+<h3>Parquet Page Index Improvements</h3>
+<p><a href="https://github.com/etseidl"; target="_blank"
rel="noopener">@etseidl</a> made several improvements to Parquet page index
handling: a new
+<a
href="https://docs.rs/parquet/60.0.0/parquet/file/metadata/page_index/struct.PageIndex.html";
target="_blank" rel="noopener"><code>PageIndex</code></a> struct encapsulating
column and offset indexes (<a
href="https://github.com/apache/arrow-rs/pull/10719"; target="_blank"
rel="noopener">#10719</a>), new
+<a
href="https://docs.rs/parquet/60.0.0/parquet/file/metadata/page_index/struct.PageIndexBuilder.html";
target="_blank" rel="noopener"><code>PageIndexBuilder</code></a> and <a
href="https://docs.rs/parquet/60.0.0/parquet/file/metadata/page_index/trait.PageIndexProvider.html";
target="_blank" rel="noopener"><code>PageIndexProvider</code></a> types (<a
href="https://github.com/apache/arrow-rs/pull/10842"; target="_blank"
rel="noopener">#10842</a>), and page index
+decoders are now public (<a
href="https://github.com/apache/arrow-rs/pull/10899"; target="_blank"
rel="noopener">#10899</a>). One major use case enabled by these
+changes is supplying external or cached <code>PageIndex</code>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.</p>
+<h3>Parquet NDV Statistics, FILE Logical Type, and IEEE 754 Total Order</h3>
+<p><a href="https://github.com/Rich-T-kid"; target="_blank"
rel="noopener">@Rich-T-kid</a> implemented writing num distinct values (NDV)
statistics in the
+Parquet writer (<a href="https://github.com/apache/arrow-rs/pull/10654";
target="_blank" rel="noopener">#10654</a>) and added row-group-level distinct
counts to
+<code>StatisticsConverter</code> (<a
href="https://github.com/apache/arrow-rs/pull/10652"; target="_blank"
rel="noopener">#10652</a>). Query engines use these to make better
+planning decisions such as join strategy selection and filter selectivity
+estimates.</p>
+<p><a href="https://github.com/brkyvz"; target="_blank"
rel="noopener">@brkyvz</a> added support for the <code>FILE</code> logical type
(<a href="https://github.com/apache/arrow-rs/pull/10109"; target="_blank"
rel="noopener">#10109</a>). <a href="https://github.com/etseidl";
target="_blank" rel="noopener">@etseidl</a>
+implemented <a href="https://issues.apache.org/jira/browse/PARQUET-2249";
target="_blank" rel="noopener">PARQUET-2249</a> IEEE 754 total order for
floating-point comparisons
+(<a href="https://github.com/apache/arrow-rs/pull/9619"; target="_blank"
rel="noopener">#9619</a>) and the corresponding <code>INT96</code> timestamp
<code>ColumnOrder</code> (<a
href="https://github.com/apache/arrow-rs/pull/10106"; target="_blank"
rel="noopener">#10106</a>).
+<a href="https://github.com/etseidl"; target="_blank"
rel="noopener">@etseidl</a> also removed the previous limit of 32,768 row
groups per file
+(<a href="https://github.com/apache/arrow-rs/pull/10149"; target="_blank"
rel="noopener">#10149</a>).</p>
+<h3>New <code>arrow-cmp</code> Crate</h3>
+<p><a href="https://github.com/Rich-T-kid"; target="_blank"
rel="noopener">@Rich-T-kid</a> introduced the <a
href="https://crates.io/crates/arrow-cmp"; target="_blank"
rel="noopener"><code>arrow-cmp</code></a> crate (<a
href="https://github.com/apache/arrow-rs/pull/10325"; target="_blank"
rel="noopener">#10325</a>), splitting
+comparison kernel logic out of <a href="https://crates.io/crates/arrow-ord";
target="_blank" rel="noopener"><code>arrow-ord</code></a> into its own focused
crate. This
+gives users a more targeted dependency for Arrow comparison operations without
+pulling in the broader <code>arrow-ord</code> crate.</p>
+<h2>Panic Elimination</h2>
+<p>A lot of work went into converting panics into proper <code>Result</code>
returns this
+release. <a href="https://github.com/emilk"; target="_blank"
rel="noopener">@emilk</a> fixed <code>try_</code> functions still panicking in
edge cases (<a href="https://github.com/apache/arrow-rs/pull/10730";
target="_blank" rel="noopener">#10730</a>,
+<a href="https://github.com/apache/arrow-rs/pull/10755"; target="_blank"
rel="noopener">#10755</a>) and removed panics from
<code>GenericByteArray::from_iter_values</code> (<a
href="https://github.com/apache/arrow-rs/pull/10729"; target="_blank"
rel="noopener">#10729</a>).
+<a href="https://github.com/bit2swaz"; target="_blank"

+<h2>Performance Improvements</h2>
+<p>This release has a large number of performance improvements across kernels,
+casting, and Parquet I/O.</p>
+<h3>Take/Filter Kernel Improvements</h3>
+<p><a href="https://github.com/Rich-T-kid"; target="_blank"
rel="noopener">@Rich-T-kid</a> landed a series of take/filter kernel speedups
this release:
+<code>take</code> on <code>FixedSizeList</code> is up to <strong>3.3x
faster</strong> (<a href="https://github.com/apache/arrow-rs/pull/10441";
target="_blank" rel="noopener">#10441</a>), <code>take</code> on
+<code>List<T></code> up to <strong>1.8x faster</strong> (<a
href="https://github.com/apache/arrow-rs/pull/10812"; target="_blank"
rel="noopener">#10812</a>), <code>take</code> on boolean and null buffers
+up to <strong>1.7x faster</strong> (<a
href="https://github.com/apache/arrow-rs/pull/10813"; target="_blank"
rel="noopener">#10813</a>), and <code>filter</code> on
<code>FixedSizeBinary</code> up to
+<strong>1.4x faster</strong> (<a
href="https://github.com/apache/arrow-rs/pull/10993"; target="_blank"
rel="noopener">#10993</a>). A <code>NullBuffer::expand</code> rewrite for
aligned counts
+delivers up to <strong>143x faster</strong> buffer expansion (<a
href="https://github.com/apache/arrow-rs/pull/10976"; target="_blank"
rel="noopener">#10976</a>, <a
href="https://github.com/apache/arrow-rs/pull/10980"; target="_blank"
rel="noopener">#10980</a>).</p>
+<p><a href="https://github.com/YUZHEthefool"; target="_blank"
rel="noopener">@YUZHEthefool</a> improved <code>rank</code> on
<code>StringViewArray</code> by up to <strong>3.2x faster</strong>
+via prefix key caching (<a
href="https://github.com/apache/arrow-rs/pull/10605"; target="_blank"
rel="noopener">#10605</a>). <a href="https://github.com/giladkl";
target="_blank" rel="noopener">@giladkl</a> made equality/inequality
+comparisons of byte-view arrays against short scalars up to <strong>2.5x
faster</strong>
+(<a href="https://github.com/apache/arrow-rs/pull/10689"; target="_blank"
rel="noopener">#10689</a>). <a href="https://github.com/cakeni"; target="_blank"
rel="noopener">@cakeni</a> replaced <code>BufferBuilder</code> with
<code>Vec</code> across
+<code>concat_elements</code>, <code>take_run</code>, <code>substring</code>,
and other kernels
+(<a href="https://github.com/apache/arrow-rs/pull/10629"; target="_blank"
rel="noopener">#10629</a>-<a
href="https://github.com/apache/arrow-rs/pull/10634"; target="_blank"
rel="noopener">#10634</a>), and <a href="https://github.com/kowanietz";
target="_blank" rel="noopener">@kowanietz</a> did the same for primitive unary
+operations (<a href="https://github.com/apache/arrow-rs/pull/10783";
target="_blank" rel="noopener">#10783</a>) and fixed-size binary take (<a
href="https://github.com/apache/arrow-rs/pull/10773"; target="_blank"
rel="noopener">#10773</a>), cutting
+unnecessary allocations across the board. <a
href="https://github.com/haohuaijin"; target="_blank"
rel="noopener">@haohuaijin</a> fixed in-place
+bitwise ops corrupting bits outside the requested range (<a
href="https://github.com/apache/arrow-rs/pull/10444"; target="_blank"
rel="noopener">#10444</a>).</p>
+<h3>Decimal Casting</h3>
+<p><a href="https://github.com/neilconway"; target="_blank"
rel="noopener">@neilconway</a> made decimal parsing dramatically faster across
the board. A
+foundational rewrite of the decimal-from-string path (<a
href="https://github.com/apache/arrow-rs/pull/10668"; target="_blank"
rel="noopener">#10668</a>) alone delivers
+<strong>up to ~8x faster</strong> casting from strings to
<code>Decimal128</code> and up to <strong>92% lower parsing time</strong>
+on individual parse microbenchmarks. A follow-up pass for separate
+integer/fractional digit scanning (<a
href="https://github.com/apache/arrow-rs/pull/10974"; target="_blank"
rel="noopener">#10974</a>) added another <strong>5–15%</strong> on top,
+and skipping redundant precision checks (<a
href="https://github.com/apache/arrow-rs/pull/10998"; target="_blank"
rel="noopener">#10998</a>) added up to <strong>~10%</strong> more.
+Formatting <code>i256</code> without <code>num-bigint</code> (<a
href="https://github.com/apache/arrow-rs/pull/11000"; target="_blank"
rel="noopener">#11000</a>) rounds things out with
+<strong>~1.8x faster</strong> <code>Decimal256</code> formatting for typical
38-digit values.</p>
+<h3>Parquet Reading Improvements</h3>
+<p>Plain Parquet string column reads into dictionary arrays are <strong>~1.5x
faster</strong>
+(<a href="https://github.com/apache/arrow-rs/pull/10614"; target="_blank"
rel="noopener">#10614</a>). <a href="https://github.com/adriangb";
target="_blank" rel="noopener">@adriangb</a> sped up
<code>DELTA_BYTE_ARRAY</code> shared-prefix decoding by
+scanning a block at a time (<a
href="https://github.com/apache/arrow-rs/pull/10549"; target="_blank"
rel="noopener">#10549</a>), reaching <strong>up to 19x faster</strong> on the
+prefix-scan microbenchmark and <strong>4.2x faster</strong> end-to-end for
small
+shared-prefix strings. <a href="https://github.com/haohuaijin"; target="_blank"
rel="noopener">@haohuaijin</a> removed redundant copies in Parquet
+mask-backed intersection/union (<a
href="https://github.com/apache/arrow-rs/pull/10446"; target="_blank"
rel="noopener">#10446</a>), delivering <strong>2–6x faster</strong> mask
+operations depending on alignment. <a href="https://github.com/hhhizzz";
target="_blank" rel="noopener">@hhhizzz</a> fixed cached Mask reads crossing
+unloaded sparse pages (<a href="https://github.com/apache/arrow-rs/pull/10735";
target="_blank" rel="noopener">#10735</a>).</p>
+<h3>Binary Size Reduction</h3>
+<p><a href="https://github.com/alamb"; target="_blank"
rel="noopener">@alamb</a> reduced binary size by about <strong>2%</strong> by
monomorphizing <code>PrimitiveArray</code>
+to <code>ArrayData</code> conversion and <code>Debug</code> formatting helpers
(<a href="https://github.com/apache/arrow-rs/pull/10893"; target="_blank"
rel="noopener">#10893</a>, <a
href="https://github.com/apache/arrow-rs/pull/10890"; target="_blank"
rel="noopener">#10890</a>) —
+the Debug change alone cut <strong>~12% of LLVM IR</strong> from the
<code>cast_kernels</code> binary.</p>
+<h2>Bug Fixes</h2>
+<p><a href="https://github.com/neilconway"; target="_blank"
rel="noopener">@neilconway</a> fixed a cluster of decimal bugs including
incorrect <code>Decimal256</code>
+casting to signed integers (<a
href="https://github.com/apache/arrow-rs/pull/10857"; target="_blank"
rel="noopener">#10857</a>), wrong min/max statistics for <code>BYTE_ARRAY</code>
+decimals (<a href="https://github.com/apache/arrow-rs/pull/10861";
target="_blank" rel="noopener">#10861</a>), mismatched scales in
<code>make_comparator</code> (<a
href="https://github.com/apache/arrow-rs/pull/10864"; target="_blank"
rel="noopener">#10864</a>),
+formatting bugs (<a href="https://github.com/apache/arrow-rs/pull/10869";
target="_blank" rel="noopener">#10869</a>), and a spurious assert when
<code>scale == precision</code>
+(<a href="https://github.com/apache/arrow-rs/pull/10875"; target="_blank"
rel="noopener">#10875</a>).</p>
+<p><a href="https://github.com/yongster"; target="_blank"

not
+accounting for parent offsets (<a
href="https://github.com/apache/arrow-rs/pull/10970"; target="_blank"
rel="noopener">#10970</a>).</p>
+<p><a href="https://github.com/PlenoraETL"; target="_blank"
rel="noopener">@PlenoraETL</a> made the IPC reader return an error for a
<code>DictionaryBatch</code>
+missing its data instead of silently producing wrong results (<a
href="https://github.com/apache/arrow-rs/pull/11020"; target="_blank"
rel="noopener">#11020</a>).
+<a href="https://github.com/bit2swaz"; target="_blank"
rel="noopener">@bit2swaz</a> made <code>FFI_ArrowSchema::with_metadata</code>
<code>unsafe</code> to close a
+soundness gap (<a href="https://github.com/apache/arrow-rs/pull/10764";
target="_blank" rel="noopener">#10764</a>).</p>
+<p><a href="https://github.com/adriangb"; target="_blank"
rel="noopener">@adriangb</a> fixed <code>DELTA_BYTE_ARRAY</code> deduplication
for values larger than
+the page size limit (<a href="https://github.com/apache/arrow-rs/pull/10505";
target="_blank" rel="noopener">#10505</a>).</p>
+<h2>Other Notable Changes</h2>
+<ul>
+<li>
+<a href="https://github.com/adamreeve"; target="_blank"
rel="noopener">@adamreeve</a> added round-trip support for <code>Dictionary(_,
Utf8View/BinaryView)</code>
+columns in Parquet (<a href="https://github.com/apache/arrow-rs/pull/10831";
target="_blank" rel="noopener">#10831</a>)</li>
+<li>
+<a href="https://github.com/ranflarion"; target="_blank"
rel="noopener">@ranflarion</a> improved Parquet bloom filters: populate from
the dictionary
+while a column is dictionary encoded (<a
href="https://github.com/apache/arrow-rs/pull/10966"; target="_blank"
rel="noopener">#10966</a>) and added a writer option to

rel="noopener">#10963</a>)</li>
+<li>
+<a href="https://github.com/haohuaijin"; target="_blank"
rel="noopener">@haohuaijin</a> added row-group-local <code>RowSelection</code>

target="_blank" rel="noopener">#10702</a>)</li>
+<li>
+<a href="https://github.com/1fanwang"; target="_blank"
rel="noopener">@1fanwang</a> added <code>Utf8View</code> and
<code>BinaryView</code> support to <code>substring</code> (<a
href="https://github.com/apache/arrow-rs/pull/10672"; target="_blank"
rel="noopener">#10672</a>)</li>
+<li>
+<a href="https://github.com/etseidl"; target="_blank"
rel="noopener">@etseidl</a> removed previously deprecated Parquet functions (<a
href="https://github.com/apache/arrow-rs/pull/10565"; target="_blank"

href="https://github.com/apache/arrow-rs/pull/10104"; target="_blank"
rel="noopener">#10104</a>) as a follow-up to
+the INT96/IEEE 754 correctness work — both are breaking changes users will

+<p>The Apache Arrow team is pleased to announce that the v60.0.0 release of
Apache Arrow
+Rust is now available on crates.io (<a
href="https://crates.io/crates/arrow";>arrow</a> and <a
href="https://crates.io/crates/parquet";>parquet</a>) and as <a
href="https://dist.apache.org/repos/dist/release/arrow/arrow-rs-60.0.0";>source
download</a>.</p>
+<p>See the <a
href="https://github.com/apache/arrow-rs/blob/60.0.0/CHANGELOG.md";>60.0.0
changelog</a> for a full list of changes.</p>
+<h2>Highlights</h2>
+<p>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.</p>
+<p>MSRV is bumped to 1.88,
+<code>rand</code> upgraded to 0.10, <code>object_store</code> to 0.14.1, and
several long-deprecated
+items have been removed. See the <a
href="https://github.com/apache/arrow-rs/blob/60.0.0/CHANGELOG.md";>60.0.0
changelog</a> for the full breaking
+changes list.</p>
+<h2>New Features</h2>
+<h3>Parquet ALP Encoder/Decoder Support</h3>
+<p><a href="https://github.com/sdf-jkl";>@sdf-jkl</a> added support for the <a
href="https://parquet.apache.org/blog/2026/09/22/alp-adaptive-lossless-floating-point-encoding-in-apache-parquet/";>Adaptive
Lossless Floating-Point (ALP)</a>
+encoding in Parquet (<a
href="https://github.com/apache/arrow-rs/pull/9372";>#9372</a>). 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 <a href="https://crates.io/crates/parquet";>parquet</a> crate
aligned with the latest Parquet specification.</p>
+<h3>Parquet Page Index Improvements</h3>
+<p><a href="https://github.com/etseidl";>@etseidl</a> made several improvements
to Parquet page index handling: a new
+<a
href="https://docs.rs/parquet/60.0.0/parquet/file/metadata/page_index/struct.PageIndex.html";><code>PageIndex</code></a>
struct encapsulating column and offset indexes (<a
href="https://github.com/apache/arrow-rs/pull/10719";>#10719</a>), new
+<a
href="https://docs.rs/parquet/60.0.0/parquet/file/metadata/page_index/struct.PageIndexBuilder.html";><code>PageIndexBuilder</code></a>
and <a
href="https://docs.rs/parquet/60.0.0/parquet/file/metadata/page_index/trait.PageIndexProvider.html";><code>PageIndexProvider</code></a>
types (<a href="https://github.com/apache/arrow-rs/pull/10842";>#10842</a>),
and page index
+decoders are now public (<a
href="https://github.com/apache/arrow-rs/pull/10899";>#10899</a>). One major use
case enabled by these
+changes is supplying external or cached <code>PageIndex</code>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.</p>
+<h3>Parquet NDV Statistics, FILE Logical Type, and IEEE 754 Total Order</h3>
+<p><a href="https://github.com/Rich-T-kid";>@Rich-T-kid</a> implemented writing
num distinct values (NDV) statistics in the
+Parquet writer (<a
href="https://github.com/apache/arrow-rs/pull/10654";>#10654</a>) and added
row-group-level distinct counts to
+<code>StatisticsConverter</code> (<a
href="https://github.com/apache/arrow-rs/pull/10652";>#10652</a>). Query engines
use these to make better
+planning decisions such as join strategy selection and filter selectivity
+estimates.</p>
+<p><a href="https://github.com/brkyvz";>@brkyvz</a> added support for the
<code>FILE</code> logical type (<a
href="https://github.com/apache/arrow-rs/pull/10109";>#10109</a>). <a
href="https://github.com/etseidl";>@etseidl</a>
+implemented <a
href="https://issues.apache.org/jira/browse/PARQUET-2249";>PARQUET-2249</a> IEEE
754 total order for floating-point comparisons
+(<a href="https://github.com/apache/arrow-rs/pull/9619";>#9619</a>) and the
corresponding <code>INT96</code> timestamp <code>ColumnOrder</code> (<a
href="https://github.com/apache/arrow-rs/pull/10106";>#10106</a>).
+<a href="https://github.com/etseidl";>@etseidl</a> also removed the previous
limit of 32,768 row groups per file
+(<a href="https://github.com/apache/arrow-rs/pull/10149";>#10149</a>).</p>
+<h3>New <code>arrow-cmp</code> Crate</h3>
+<p><a href="https://github.com/Rich-T-kid";>@Rich-T-kid</a> introduced the <a
href="https://crates.io/crates/arrow-cmp";><code>arrow-cmp</code></a> crate (<a
href="https://github.com/apache/arrow-rs/pull/10325";>#10325</a>), splitting
+comparison kernel logic out of <a
href="https://crates.io/crates/arrow-ord";><code>arrow-ord</code></a> into its
own focused crate. This
+gives users a more targeted dependency for Arrow comparison operations without
+pulling in the broader <code>arrow-ord</code> crate.</p>
+<h2>Panic Elimination</h2>
+<p>A lot of work went into converting panics into proper <code>Result</code>
returns this
+release. <a href="https://github.com/emilk";>@emilk</a> fixed <code>try_</code>
functions still panicking in edge cases (<a
href="https://github.com/apache/arrow-rs/pull/10730";>#10730</a>,
+<a href="https://github.com/apache/arrow-rs/pull/10755";>#10755</a>) and
removed panics from <code>GenericByteArray::from_iter_values</code> (<a
href="https://github.com/apache/arrow-rs/pull/10729";>#10729</a>).
+<a href="https://github.com/bit2swaz";>@bit2swaz</a> replaced panics with
errors in IPC schema and footer parsing
+(<a href="https://github.com/apache/arrow-rs/pull/10647";>#10647</a>, <a
href="https://github.com/apache/arrow-rs/pull/10744";>#10744</a>) and closed an
FFI <code>Drop</code> soundness hole (<a
href="https://github.com/apache/arrow-rs/pull/10431";>#10431</a>).
+<a href="https://github.com/Rich-T-kid";>@Rich-T-kid</a> fixed a potential
use-after-free in <code>Buffer::shrink_to_fit</code> (<a
href="https://github.com/apache/arrow-rs/pull/10932";>#10932</a>)
+and converted <code>MutableBuffer</code> panicking callsites to fallible
methods (<a href="https://github.com/apache/arrow-rs/pull/10641";>#10641</a>,
+<a href="https://github.com/apache/arrow-rs/pull/10317";>#10317</a>). <a
href="https://github.com/okhsunrog";>@okhsunrog</a> made
<code>interleave</code>/<code>concat</code> return errors on dictionary key
+overflow (<a href="https://github.com/apache/arrow-rs/pull/10675";>#10675</a>).
<a href="https://github.com/ranflarion";>@ranflarion</a> converted a Parquet
buffer push panic into an
+error (<a href="https://github.com/apache/arrow-rs/pull/10564";>#10564</a>) and
<a href="https://github.com/dhruvxvaishnav";>@dhruvxvaishnav</a> did the same
for invalid dictionary index
+bit widths (<a
href="https://github.com/apache/arrow-rs/pull/10725";>#10725</a>).</p>
+<h2>Performance Improvements</h2>
+<p>This release has a large number of performance improvements across kernels,
+casting, and Parquet I/O.</p>
+<h3>Take/Filter Kernel Improvements</h3>
+<p><a href="https://github.com/Rich-T-kid";>@Rich-T-kid</a> landed a series of
take/filter kernel speedups this release:
+<code>take</code> on <code>FixedSizeList</code> is up to <strong>3.3x
faster</strong> (<a
href="https://github.com/apache/arrow-rs/pull/10441";>#10441</a>),
<code>take</code> on
+<code>List<T></code> up to <strong>1.8x faster</strong> (<a
href="https://github.com/apache/arrow-rs/pull/10812";>#10812</a>),
<code>take</code> on boolean and null buffers
+up to <strong>1.7x faster</strong> (<a
href="https://github.com/apache/arrow-rs/pull/10813";>#10813</a>), and
<code>filter</code> on <code>FixedSizeBinary</code> up to
+<strong>1.4x faster</strong> (<a
href="https://github.com/apache/arrow-rs/pull/10993";>#10993</a>). A
<code>NullBuffer::expand</code> rewrite for aligned counts
+delivers up to <strong>143x faster</strong> buffer expansion (<a
href="https://github.com/apache/arrow-rs/pull/10976";>#10976</a>, <a
href="https://github.com/apache/arrow-rs/pull/10980";>#10980</a>).</p>
+<p><a href="https://github.com/YUZHEthefool";>@YUZHEthefool</a> improved
<code>rank</code> on <code>StringViewArray</code> by up to <strong>3.2x
faster</strong>
+via prefix key caching (<a
href="https://github.com/apache/arrow-rs/pull/10605";>#10605</a>). <a
href="https://github.com/giladkl";>@giladkl</a> made equality/inequality
+comparisons of byte-view arrays against short scalars up to <strong>2.5x
faster</strong>
+(<a href="https://github.com/apache/arrow-rs/pull/10689";>#10689</a>). <a
href="https://github.com/cakeni";>@cakeni</a> replaced
<code>BufferBuilder</code> with <code>Vec</code> across
+<code>concat_elements</code>, <code>take_run</code>, <code>substring</code>,
and other kernels
+(<a href="https://github.com/apache/arrow-rs/pull/10629";>#10629</a>-<a
href="https://github.com/apache/arrow-rs/pull/10634";>#10634</a>), and <a
href="https://github.com/kowanietz";>@kowanietz</a> did the same for primitive
unary
+operations (<a
href="https://github.com/apache/arrow-rs/pull/10783";>#10783</a>) and fixed-size
binary take (<a
href="https://github.com/apache/arrow-rs/pull/10773";>#10773</a>), cutting
+unnecessary allocations across the board. <a
href="https://github.com/haohuaijin";>@haohuaijin</a> fixed in-place
+bitwise ops corrupting bits outside the requested range (<a
href="https://github.com/apache/arrow-rs/pull/10444";>#10444</a>).</p>
+<h3>Decimal Casting</h3>
+<p><a href="https://github.com/neilconway";>@neilconway</a> made decimal
parsing dramatically faster across the board. A
+foundational rewrite of the decimal-from-string path (<a
href="https://github.com/apache/arrow-rs/pull/10668";>#10668</a>) alone delivers
+<strong>up to ~8x faster</strong> casting from strings to
<code>Decimal128</code> and up to <strong>92% lower parsing time</strong>
+on individual parse microbenchmarks. A follow-up pass for separate
+integer/fractional digit scanning (<a
href="https://github.com/apache/arrow-rs/pull/10974";>#10974</a>) added another
<strong>5–15%</strong> on top,
+and skipping redundant precision checks (<a
href="https://github.com/apache/arrow-rs/pull/10998";>#10998</a>) added up to
<strong>~10%</strong> more.
+Formatting <code>i256</code> without <code>num-bigint</code> (<a
href="https://github.com/apache/arrow-rs/pull/11000";>#11000</a>) rounds things
out with
+<strong>~1.8x faster</strong> <code>Decimal256</code> formatting for typical
38-digit values.</p>
+<h3>Parquet Reading Improvements</h3>
+<p>Plain Parquet string column reads into dictionary arrays are <strong>~1.5x
faster</strong>
+(<a href="https://github.com/apache/arrow-rs/pull/10614";>#10614</a>). <a
href="https://github.com/adriangb";>@adriangb</a> sped up
<code>DELTA_BYTE_ARRAY</code> shared-prefix decoding by
+scanning a block at a time (<a
href="https://github.com/apache/arrow-rs/pull/10549";>#10549</a>), reaching
<strong>up to 19x faster</strong> on the
+prefix-scan microbenchmark and <strong>4.2x faster</strong> end-to-end for
small
+shared-prefix strings. <a href="https://github.com/haohuaijin";>@haohuaijin</a>
removed redundant copies in Parquet
+mask-backed intersection/union (<a
href="https://github.com/apache/arrow-rs/pull/10446";>#10446</a>), delivering
<strong>2–6x faster</strong> mask
+operations depending on alignment. <a
href="https://github.com/hhhizzz";>@hhhizzz</a> fixed cached Mask reads crossing
+unloaded sparse pages (<a
href="https://github.com/apache/arrow-rs/pull/10735";>#10735</a>).</p>
+<h3>Binary Size Reduction</h3>
+<p><a href="https://github.com/alamb";>@alamb</a> reduced binary size by about
<strong>2%</strong> by monomorphizing <code>PrimitiveArray</code>
+to <code>ArrayData</code> conversion and <code>Debug</code> formatting helpers
(<a href="https://github.com/apache/arrow-rs/pull/10893";>#10893</a>, <a
href="https://github.com/apache/arrow-rs/pull/10890";>#10890</a>) —
+the Debug change alone cut <strong>~12% of LLVM IR</strong> from the
<code>cast_kernels</code> binary.</p>
+<h2>Bug Fixes</h2>
+<p><a href="https://github.com/neilconway";>@neilconway</a> fixed a cluster of
decimal bugs including incorrect <code>Decimal256</code>
+casting to signed integers (<a
href="https://github.com/apache/arrow-rs/pull/10857";>#10857</a>), wrong min/max
statistics for <code>BYTE_ARRAY</code>
+decimals (<a href="https://github.com/apache/arrow-rs/pull/10861";>#10861</a>),
mismatched scales in <code>make_comparator</code> (<a
href="https://github.com/apache/arrow-rs/pull/10864";>#10864</a>),
+formatting bugs (<a
href="https://github.com/apache/arrow-rs/pull/10869";>#10869</a>), and a
spurious assert when <code>scale == precision</code>
+(<a href="https://github.com/apache/arrow-rs/pull/10875";>#10875</a>).</p>
+<p><a href="https://github.com/yongster";>@yongster</a> fixed <code>take</code>
for null indices in dense union and run-end encoded
+arrays (<a
href="https://github.com/apache/arrow-rs/pull/10909";>#10909</a>).</p>
+<p><a href="https://github.com/1fanwang";>@1fanwang</a> and <a
href="https://github.com/tpoterba";>@tpoterba</a> fixed <code>take</code> and
<code>interleave</code> on zero-width
+<code>FixedSizeListArray</code> (<a
href="https://github.com/apache/arrow-rs/pull/10915";>#10915</a>, <a
href="https://github.com/apache/arrow-rs/pull/11026";>#11026</a>).</p>
+<p><a href="https://github.com/jaideeppyne";>@jaideeppyne</a> fixed struct
<code>ArrayData</code> slicing double-counting the offset
+(<a href="https://github.com/apache/arrow-rs/pull/10835";>#10835</a>, <a
href="https://github.com/apache/arrow-rs/pull/10934";>#10934</a>). <a
href="https://github.com/linhongyu510";>@linhongyu510</a> fixed struct null
validation not
+accounting for parent offsets (<a
href="https://github.com/apache/arrow-rs/pull/10970";>#10970</a>).</p>
+<p><a href="https://github.com/PlenoraETL";>@PlenoraETL</a> made the IPC reader
return an error for a <code>DictionaryBatch</code>
+missing its data instead of silently producing wrong results (<a
href="https://github.com/apache/arrow-rs/pull/11020";>#11020</a>).
+<a href="https://github.com/bit2swaz";>@bit2swaz</a> made
<code>FFI_ArrowSchema::with_metadata</code> <code>unsafe</code> to close a
+soundness gap (<a
href="https://github.com/apache/arrow-rs/pull/10764";>#10764</a>).</p>
+<p><a href="https://github.com/adriangb";>@adriangb</a> fixed
<code>DELTA_BYTE_ARRAY</code> deduplication for values larger than
+the page size limit (<a
href="https://github.com/apache/arrow-rs/pull/10505";>#10505</a>).</p>
+<h2>Other Notable Changes</h2>
+<ul>
+<li><a href="https://github.com/adamreeve";>@adamreeve</a> added round-trip
support for <code>Dictionary(_, Utf8View/BinaryView)</code>
+columns in Parquet (<a
href="https://github.com/apache/arrow-rs/pull/10831";>#10831</a>)</li>
+<li><a href="https://github.com/ranflarion";>@ranflarion</a> improved Parquet
bloom filters: populate from the dictionary
+while a column is dictionary encoded (<a
href="https://github.com/apache/arrow-rs/pull/10966";>#10966</a>) and added a
writer option to
+skip bloom filters for all-dictionary column chunks (<a
href="https://github.com/apache/arrow-rs/pull/10963";>#10963</a>)</li>
+<li><a href="https://github.com/haohuaijin";>@haohuaijin</a> added
row-group-local <code>RowSelection</code> support to the push
+decoder (<a
href="https://github.com/apache/arrow-rs/pull/10702";>#10702</a>)</li>
+<li><a href="https://github.com/1fanwang";>@1fanwang</a> added
<code>Utf8View</code> and <code>BinaryView</code> support to
<code>substring</code> (<a
href="https://github.com/apache/arrow-rs/pull/10672";>#10672</a>)</li>
+<li><a href="https://github.com/etseidl";>@etseidl</a> removed previously
deprecated Parquet functions (<a
href="https://github.com/apache/arrow-rs/pull/10565";>#10565</a>) and
+deprecated <code>ColumnOrder::sort_order_for_type</code> (<a
href="https://github.com/apache/arrow-rs/pull/10104";>#10104</a>) as a follow-up
to
+the INT96/IEEE 754 correctness work — both are breaking changes users will
+notice at compile time.</li>

-<h2>Release, Packaging and CI</h2>
-<p>A lot of work has been done around the Continuous Integration and
-Developer Tools area. Ensuring a project with the reach of Arrow is properly
working
-requires validation on a huge matrix of operating systems, architectures,
libraries,
-versions. Needless to say that maintenance work has tremendous importance for
the
-health of the project and the positive contributor experience.</p>
-<p>The most active contributors in the main repository are the ones
contributing
-heavily on those areas while also providing the most review capacity. Shout out
-to <a href="https://github.com/kou";>kou</a> and <a
href="https://github.com/raulcd";>raulcd</a> for
-taking such good care of the project and devoting countless hours so that
everything
-runs smoothly.</p>
-<p>Notable contributions worth mentioning are enhanced release automation and
-reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
-to GitHub actions, improving dev experience with more pre-commit checks instead
-of custom made linting tools.</p>
-<p>Moving some implementations out of the main repository (apache/arrow on
GitHub)
-helped with easier releases and maintenance of the main repository and also of
-separate language implementations. The current apache/arrow repo now holds the
format
-specification, C++ implementation together with all the bindings to it
(Python, R, Ruby
-and C GLib). Other languages now live in their own apache/ repos namely

-<h2>Migration of infrastructure from Voltron Data</h2>
-<p>As Voltron Data has wound down its operations in 2025, the Arrow project
-had to migrate benchmarking infrastructure and nightly report from
-Voltron-managed services to an Arrow-managed AWS account. This work has been
-driven by <a href="https://github.com/rok";>rok</a>.</p>
-<h2>Closing of Stale issues</h2>
-<p><a href="https://github.com/thisisnic";>thisisnic</a> was working on closing
of stale
-issues in the apache/arrow repository which helped surfacing important
-issues that were overlooked or forgotten.</p>
-<h2>Code contributions</h2>
-<h3>C++ implementation</h3>
-<p>Community support for maintenance and development of the Acero C++
-is continuing with multiple bigger contributions in 2025 done by
-<a href="https://github.com/pitrou";>pitrou</a> and <a
href="https://github.com/zanmato1984";>zanmato1984</a>.</p>
-<p>Many kernels have been moved from the integrated compute module into
-a separate, optional package for improvement of modularity and distribution
-size when optional compute functionality is not being used. The work has
-been done by <a href="https://github.com/raulcd";>raulcd</a>.</p>
-<h3>Arrow C++ Parquet implementation</h3>
-<p>There have been multiple contributions to fix and improve fuzzing
-support for Parquet. Fuzzing work is led by <a
href="https://github.com/pitrou";>pitrou</a>
-who is also one of the most active members of the community guiding other
-developers and supporting us with abundant review capacity.</p>
-<p>Multiple newer types have also been supported in the last year,
-namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
-by <a href="https://github.com/neilechao";>neilechao</a> and
-<a href="https://github.com/paleolimbot";>paleolimbot</a>.</p>
-<p>An important feature added has also been Content-Defined Chunking
-which improves deduplication of Parquet files with mostly identical
-contents, by choosing data page boundaries based on actual contents
-rather than a number of values <sup class="footnote-ref"><a href="#fn3"
id="fnref3">3</a></sup>. This work has been done by
-<a href="https://github.com/kszucs";>kszucs</a>.</p>
-<p>There have been improvements in the Parquet encryption support for
-most of the releases in the last year. These efforts have been
-driven mostly by <a href="https://github.com/EnricoMi";>EnricoMi</a>,
-<a href="https://github.com/pitrou";>pitrou</a>, <a
href="https://github.com/adamreeve";>adamreeve</a>
-and <a href="https://github.com/kapoisu";>kapoisu</a>.</p>
-<h3>PyArrow</h3>
-<p>A lot of work has been put into adding type annotations. It all
-started in July at EuroPython sprints and the code is now ready to be
-reviewed and merged. Some more review capacity will be needed to get
-this over the finish line. The work has been championed by
-<a href="https://github.com/rok";>rok</a>.</p>
-<h3>Rust</h3>
-<p>Arrow Rust community invested heavily in the Rust parquet reader for
-which they created several blog posts <sup class="footnote-ref"><a href="#fn4"
id="fnref4">4</a></sup>, <sup class="footnote-ref"><a href="#fn5"
id="fnref5">5</a></sup>. The work has been
-championed by <a href="https://github.com/alamb";>alamb</a> and
-<a href="https://github.com/etseidl";>etseidl</a>.</p>

-<h3>Java</h3>
-<p>The biggest changes in apache/arrow-java for 2025 have been connected
-to Flight and Avro components plus Sphinx support due to the Java
-implementation being moved into a separate Apache repository.
-Contributors involved in the above are <a
href="https://github.com/lidavidm";>lidavidm</a>
-and <a href="https://github.com/martin-traverse";>martin-traverse</a>.</p>
-<h3>Go</h3>
-<p>There has been a lot of work related to new variant type in the
-Parquet implementation done in apache/arrow-go all by
-<a href="https://github.com/zeroshade";>zeroshade</a>.</p>
-<p>Noticeable emphasis was also visible on performance-focused PRs leading to
-the addition of row seeking, bloom filter reading/writing, and reduction of
-allocations in the Parquet library along with significant optimization work
-in the <code>compute.Take</code> kernels. Shout out to <a
href="https://github.com/pixelherodev";>pixelherodev</a>
-and <a href="https://github.com/hamilton-earthscope";>hamilton-earthscope</a>
for the
-emphasis they placed on improving performance.</p>

-<h3>Nanoarrow</h3>
-<p>Bigger work in nanoarrow include Decimal32/64 and ListView/LargeListView
support,
-LZ4 and ZSTD decompression in the IPC reader, and broader packaging via Conan,
Homebrew,
-and vcpkg. Contributors driving most above are <a

-<h2>Arrow Summit 25</h2>
-<p>One last thing to highlight would be our first Arrow Summit 25 that
-was held in Paris in October 2025. The event was a great success and
-it brought users, contributors and maintainers together. It
-definitely was a highlight of the year for many of us. Thanks to
-<a href="https://github.com/raulcd";>raulcd</a> and <a
href="https://github.com/pitrou";>pitrou</a>
-for organizing the event.</p>

-<p>Note not all language implementations are mentioned. Some due to being
-moved into a separate repository in 2025 resulting in missing information
-for large amount of merged pull requests. Others due to having lower
-number of bigger contributions in the past year.</p>
