+ <!--
+
+-->
+<p>The Apache Arrow team is pleased to announce the 25.0.0 release. This
release
+covers over 3 months of development work and includes <a
href="https://github.com/apache/arrow/milestone/74?closed=1"; target="_blank"
rel="noopener"><strong>222 resolved
+issues</strong></a> on <a href="/release/25.0.0.html#contributors"><strong>268
distinct commits</strong></a> from <a
href="/release/25.0.0.html#contributors"><strong>66 distinct
+contributors</strong></a>. See the <a
href="https://arrow.apache.org/install/";>Install Page</a> to
+learn how to get the libraries for your platform.</p>
+<p>The release notes below are not exhaustive and only expose selected
highlights
+of the release. Many other bugfixes and improvements have been made: we refer
+you to the <a href="/release/25.0.0.html#changelog">complete changelog</a>.</p>
+<h2>Format Notes</h2>
+<p>We clarified that variadic buffers exported over the C Data Interface could
be
+null (<a href="https://github.com/apache/arrow/pull/50255"; target="_blank"
rel="noopener">GH-50255</a>). Consumers of the C Data Interface must be ready
to handle them.</p>
+<h2>Arrow Flight RPC Notes</h2>
+<p>The Flight SQL protocol was amended to let servers explicitly inform
clients whether a prepared statement contains a result set or not (<a
href="https://github.com/apache/arrow/issues/49497"; target="_blank"
rel="noopener">GH-49497</a>).</p>
+<p>Progress was made on the ODBC driver for Flight SQL, but we are not yet
distributing packages for end users at this time.</p>
+<h2>C++ Notes</h2>
+<h3>CSV</h3>
+<p>A new option <code>default_column_type</code> disables type inference for
all columns, including
+those not listed in the <code>column_types</code> mapping (<a
href="https://github.com/apache/arrow/pull/47663"; target="_blank"
rel="noopener">GH-47663</a>).</p>
+<h3>Compute</h3>
+<p>A new <code>hypot</code> compute function calculates Euclidean norms
without the avoidable
+overflow of a naive implementation
+(<a href="https://github.com/apache/arrow/pull/50198"; target="_blank"
rel="noopener">GH-50198</a>).</p>
+<p>Comparison functions have been upgraded to support StringView and
BinaryView inputs
+(<a href="https://github.com/apache/arrow/pull/49964"; target="_blank"
rel="noopener">GH-49964</a>).</p>
+<p>Sort functions and their siblings (rank, select-k) now allow configuring
per-key
+null placement, so as to emulate SQL constructs such as
+<code>ORDER BY i NULLS FIRST, j NULLS LAST</code> (<a
href="https://github.com/apache/arrow/pull/46926"; target="_blank"
rel="noopener">GH-46926</a>).</p>
+<p>Rank functions now correctly distinguish NaNs from null values in
floating-point
+arrays (<a href="https://github.com/apache/arrow/pull/45193"; target="_blank"
rel="noopener">GH-45193</a>).</p>
+<p>The <code>count</code> function now accounts for logical nulls in
run-end-encoded arrays (<a href="https://github.com/apache/arrow/pull/49908";
target="_blank" rel="noopener">GH-49908</a>).</p>
+<h3>File Systems</h3>
+<p>The <code>FileSystemFactory</code> interface, used for
dynamically-initialized filesystem
+implementations, now allows passing a set of key-value pairs in addition to a
+URI. This allows to pass sensitive initialization data, such as credentials,
+without leaking them in the URI (<a
href="https://github.com/apache/arrow/pull/50044"; target="_blank"
rel="noopener">GH-50044</a>).</p>
+<h3>IPC</h3>
+<p>We made the IPC reader stricter in a number of places, which could reject
+invalid IPC streams or files that would previously appear to read successfully
+(#49897, #50235).</p>
+<h3>Parquet</h3>
+<p>When writing a Parquet file with bloom filters enabled, bloom filters are
+automatically "folded" so as to match the configured fpp (the max false
positive
+rate) according to the actual cardinality of the data used for the filter.
+This can provide size savings, especially with the conservative default
+cardinality estimate (<a href="https://github.com/apache/arrow/pull/50008";
target="_blank" rel="noopener">GH-50008</a>).</p>
+<p>Bloom filters can be faster on some platforms thanks to vectorization (<a
href="https://github.com/apache/arrow/pull/50030"; target="_blank"
rel="noopener">GH-50030</a>).</p>
+<p>It is now possible to read and write ListView data from/to Parquet (<a
href="https://github.com/apache/arrow/pull/50160"; target="_blank"
rel="noopener">GH-50160</a>).</p>
+<h3>Miscellaneous C++ changes</h3>
+<p>On ARM64 platforms, Arrow C++ now supports dynamically dispatching to
SVE-optimized
+routines on compatible CPUs (<a
href="https://github.com/apache/arrow/pull/49756"; target="_blank"
rel="noopener">GH-49756</a>). Previously, dynamic dispatch was only supported
+on x86 platforms.</p>
+<p>Runtime CPU detection now uses xsimd instead of home-grown detection
functions
+(<a href="https://github.com/apache/arrow/pull/49940"; target="_blank"
rel="noopener">GH-49940</a>).</p>
+<p>The <code>ChunkedArray</code> class has a new method
<code>ComputeLogicalNullCount</code>, mirroring
+the existing methods of the same name on <code>Array</code> and
<code>ArrayData</code> classes (<a
href="https://github.com/apache/arrow/pull/50261"; target="_blank"
rel="noopener">GH-50261</a>).</p>
+<p>The <code>Table</code> class has a new method <code>ToTensor</code>
complementing the existing method
+of the same on the <code>RecordBatch</code> class (<a
href="https://github.com/apache/arrow/pull/41870"; target="_blank"
rel="noopener">GH-41870</a>). Both methods convert from the
+columnar format to a contiguous two-dimensional array.</p>
+<h2>Linux Packaging Notes</h2>
+<p>The release dropped support for Debian bookworm <a
href="https://github.com/apache/arrow/issues/50200"; target="_blank"
rel="noopener">GH-50200</a> due to
+the distribution reaching End Of Life.</p>
+<p>We added Reproducible Builds support for the Debian Linux Packages <a
href="https://github.com/apache/arrow/issues/49988"; target="_blank"
rel="noopener">GH-49988</a>.</p>
+<h2>Python Notes</h2>
+<h3>Compatibility notes</h3>
+<ul>
+<li>Feather reader and writer is deprecated in favour of the Arrow IPC API
+<a href="https://github.com/apache/arrow/issues/49232"; target="_blank"
rel="noopener">GH-49232</a>.</li>
+</ul>
+<h3>New features</h3>
+<ul>
+<li>
+<code>hypot</code> compute kernel is added to Arrow compute module and
accessible
+in PyArrow <a href="https://github.com/apache/arrow/issues/50197";
target="_blank" rel="noopener">GH-50197</a>.</li>
+<li>
+<code>pa.OSFile</code> now accepts open file descriptor (<code>int</code>
parameter) besides
+the <code>str</code> path <a
href="https://github.com/apache/arrow/issues/49751"; target="_blank"
rel="noopener">GH-49751</a>.</li>
+<li>Conversion from a list of individual <code>numpy.ndarrays</code> to a
<code>FixedShapeTensor</code>
+is added <a href="https://github.com/apache/arrow/issues/49644";

+<h2>R Notes</h2>
+<h3>Breaking changes</h3>
+<ul>
+<li>Arrow uint64 types are now always converted to R double (numeric) vectors,
regardless of the values. Previously, small uint64 values were converted to R
integer, which could cause inconsistent types within list columns when
different list elements had different value ranges (#50339).</li>
+</ul>
+<h3>New features</h3>
+<ul>
+<li>Field objects now support field-level metadata via $metadata and
$with_metadata() (@max-romagnoli, #33390).</li>
+<li>Parquet files now support list-columns of ordered factors (ordered
dictionaries) (#49689).</li>
+</ul>
+<h3>Minor improvements and fixes</h3>
+<ul>
+<li>Array$create() now gives a clearer error message when given a POSIXct
object with an invalid timezone (#40886).</li>
+<li>Dictionary arrays with large_string value types now convert correctly to R
factors (#39603).</li>
+<li>open_dataset() now gives a clearer error message when providing a mix of
readr and Arrow options (@Rich-T-kid, #33420).</li>
+<li>read_parquet() no longer triggers a C++ alignment warning from the Acero
source node (#46178).</li>
+<li>Schema metadata partial matching on $metadata$r no longer errors when
other metadata keys start with “r” (#50163).</li>
+<li>to_arrow() now preserves group_by() when converting from a dbplyr lazy
table (#40640).</li>
+<li>write_parquet() now correctly validates that max_rows_per_group is a
positive number (#40742).</li>
+<li>Stale S3 connections no longer cause a segfault during garbage collection
(#50009).</li>
+<li>Spurious “Invalid metadata$r” warnings are no longer emitted when reading
files with custom schema metadata (#48712).</li>
+</ul>
+<h3>Installation</h3>
+<ul>
+<li>The R package now builds under r-universe/r-wasm (#49981).</li>
+</ul>
+<h2>Ruby and C GLib Notes</h2>
+<ul>
+<li>Added fallback data type for unknown extension type: <a

+</li>
+</ul>

+<p>The Apache Arrow team is pleased to announce the 25.0.0 release. This
release
+covers over 3 months of development work and includes <a
href="https://github.com/apache/arrow/milestone/74?closed=1";><strong>222
resolved
+issues</strong></a> on <a href="/release/25.0.0.html#contributors"><strong>268
distinct commits</strong></a> from <a
href="/release/25.0.0.html#contributors"><strong>66 distinct
+contributors</strong></a>. See the <a
href="https://arrow.apache.org/install/";>Install Page</a> to
+learn how to get the libraries for your platform.</p>
+<p>The release notes below are not exhaustive and only expose selected
highlights
+of the release. Many other bugfixes and improvements have been made: we refer
+you to the <a href="/release/25.0.0.html#changelog">complete changelog</a>.</p>
+<h2>Format Notes</h2>
+<p>We clarified that variadic buffers exported over the C Data Interface could
be
+null (<a href="https://github.com/apache/arrow/pull/50255";>GH-50255</a>).
Consumers of the C Data Interface must be ready to handle them.</p>
+<h2>Arrow Flight RPC Notes</h2>
+<p>The Flight SQL protocol was amended to let servers explicitly inform
clients whether a prepared statement contains a result set or not (<a
href="https://github.com/apache/arrow/issues/49497";>GH-49497</a>).</p>
+<p>Progress was made on the ODBC driver for Flight SQL, but we are not yet
distributing packages for end users at this time.</p>
+<h2>C++ Notes</h2>
+<h3>CSV</h3>
+<p>A new option <code>default_column_type</code> disables type inference for
all columns, including
+those not listed in the <code>column_types</code> mapping (<a
href="https://github.com/apache/arrow/pull/47663";>GH-47663</a>).</p>
+<h3>Compute</h3>
+<p>A new <code>hypot</code> compute function calculates Euclidean norms
without the avoidable
+overflow of a naive implementation
+(<a href="https://github.com/apache/arrow/pull/50198";>GH-50198</a>).</p>
+<p>Comparison functions have been upgraded to support StringView and
BinaryView inputs
+(<a href="https://github.com/apache/arrow/pull/49964";>GH-49964</a>).</p>
+<p>Sort functions and their siblings (rank, select-k) now allow configuring
per-key
+null placement, so as to emulate SQL constructs such as
+<code>ORDER BY i NULLS FIRST, j NULLS LAST</code> (<a
href="https://github.com/apache/arrow/pull/46926";>GH-46926</a>).</p>
+<p>Rank functions now correctly distinguish NaNs from null values in
floating-point
+arrays (<a href="https://github.com/apache/arrow/pull/45193";>GH-45193</a>).</p>
+<p>The <code>count</code> function now accounts for logical nulls in
run-end-encoded arrays (<a
href="https://github.com/apache/arrow/pull/49908";>GH-49908</a>).</p>
+<h3>File Systems</h3>
+<p>The <code>FileSystemFactory</code> interface, used for
dynamically-initialized filesystem
+implementations, now allows passing a set of key-value pairs in addition to a
+URI. This allows to pass sensitive initialization data, such as credentials,
+without leaking them in the URI (<a
href="https://github.com/apache/arrow/pull/50044";>GH-50044</a>).</p>
+<h3>IPC</h3>
+<p>We made the IPC reader stricter in a number of places, which could reject
+invalid IPC streams or files that would previously appear to read successfully
+(#49897, #50235).</p>
+<h3>Parquet</h3>
+<p>When writing a Parquet file with bloom filters enabled, bloom filters are
+automatically "folded" so as to match the configured fpp (the max
false positive
+rate) according to the actual cardinality of the data used for the filter.
+This can provide size savings, especially with the conservative default
+cardinality estimate (<a
href="https://github.com/apache/arrow/pull/50008";>GH-50008</a>).</p>
+<p>Bloom filters can be faster on some platforms thanks to vectorization (<a
href="https://github.com/apache/arrow/pull/50030";>GH-50030</a>).</p>
+<p>It is now possible to read and write ListView data from/to Parquet (<a
href="https://github.com/apache/arrow/pull/50160";>GH-50160</a>).</p>
+<h3>Miscellaneous C++ changes</h3>
+<p>On ARM64 platforms, Arrow C++ now supports dynamically dispatching to
SVE-optimized
+routines on compatible CPUs (<a
href="https://github.com/apache/arrow/pull/49756";>GH-49756</a>). Previously,
dynamic dispatch was only supported
+on x86 platforms.</p>
+<p>Runtime CPU detection now uses xsimd instead of home-grown detection
functions
+(<a href="https://github.com/apache/arrow/pull/49940";>GH-49940</a>).</p>
+<p>The <code>ChunkedArray</code> class has a new method
<code>ComputeLogicalNullCount</code>, mirroring
+the existing methods of the same name on <code>Array</code> and
<code>ArrayData</code> classes (<a
href="https://github.com/apache/arrow/pull/50261";>GH-50261</a>).</p>
+<p>The <code>Table</code> class has a new method <code>ToTensor</code>
complementing the existing method
+of the same on the <code>RecordBatch</code> class (<a
href="https://github.com/apache/arrow/pull/41870";>GH-41870</a>). Both methods
convert from the
+columnar format to a contiguous two-dimensional array.</p>
+<h2>Linux Packaging Notes</h2>
+<p>The release dropped support for Debian bookworm <a
href="https://github.com/apache/arrow/issues/50200";>GH-50200</a> due to
+the distribution reaching End Of Life.</p>
+<p>We added Reproducible Builds support for the Debian Linux Packages <a
href="https://github.com/apache/arrow/issues/49988";>GH-49988</a>.</p>
+<h2>Python Notes</h2>
+<h3>Compatibility notes</h3>
+<ul>
