+
+-->
+<p>The Apache Arrow team is pleased to announce the 24.0.0 release. This
release
+covers over 3 months of development work and includes <a
href="https://github.com/apache/arrow/milestone/72?closed=1"; target="_blank"
rel="noopener"><strong>259 resolved
+issues</strong></a> on <a href="/release/24.0.0.html#contributors"><strong>325
distinct commits</strong></a> from <a
href="/release/24.0.0.html#contributors"><strong>57 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/24.0.0.html#changelog">complete changelog</a>.</p>
+<h2>Community</h2>
+<p>We recently published our <a
href="https://arrow.apache.org/blog/2026/03/19/arrow-2025-highlights/";>Community
Highlights for 2025</a>, check those out.</p>
+<p>Thanks everyone for your contributions and participation in the project!</p>
+<h2>Format Notes</h2>
+<p>We have written a project-wide <a
href="https://arrow.apache.org/docs/dev/format/Security.html";>Security Model</a>
+outlining what users should expect when dealing with Arrow data, especially
coming
+from untrusted sources <a href="https://github.com/apache/arrow/issues/48868";
target="_blank" rel="noopener">GH-48868</a>.</p>
+<h2>Arrow Flight RPC Notes</h2>
+<p>The ODBC driver is still a work-in-progress. The driver now builds on
Linux, but currently no builds are distributed (for any platform) (<a
href="https://github.com/apache/arrow/issues/49463"; target="_blank"
rel="noopener">GH-49463</a>).</p>
+<p>In C++, we have refactored serialization/deserialization to make low-level
functionality accessible for advanced usage (<a
href="https://github.com/apache/arrow/issues/49548"; target="_blank"
rel="noopener">GH-49548</a>).</p>
+<h2>C++ Notes</h2>
+<p>In addition to the aforementioned project-wide Security Model, we have
written
+a specific <a
href="https://arrow.apache.org/docs/dev/cpp/security.html";>Security Model for
Arrow C++</a>
+covering more concrete topics such as API usage and parameter validity <a
href="https://github.com/apache/arrow/issues/49274"; target="_blank"
rel="noopener">GH-49274</a>.</p>
+<h3>Compute</h3>
+<h3>Extension Types</h3>
+<p>The canonical type <a
href="https://arrow.apache.org/docs/format/CanonicalExtensions.html#variable-shape-tensor";>VariableShapeTensor</a>
+was finally implemented <a href="https://github.com/apache/arrow/issues/38007";
target="_blank" rel="noopener">GH-38007</a>.</p>
+<h3>Parquet</h3>
+<p><strong>Breaking change:</strong> The Arrow extension type name for Parquet
Variant columns
+used to be <code>parquet.variant</code> but has been changed to
<code>arrow.parquet.variant</code> <a
href="https://github.com/apache/arrow/issues/49081"; target="_blank"
rel="noopener">GH-49081</a>.</p>
+<p>While Parquet C++ could only read unencrypted bloom filters, it now supports
+reading encrypted bloom filters as well <a
href="https://github.com/apache/arrow/issues/48334"; target="_blank"
rel="noopener">GH-48334</a>. In addition, it can also
+write bloom filters, though only unencrypted <a
href="https://github.com/apache/arrow/issues/34785"; target="_blank"
rel="noopener">GH-34785</a>.</p>
+<p>An ambitious rewrite of the bit-unpacking utilities and optimizations has
led to
+significant performance improvements on reading some Parquet columns, up to 50%
+faster in some cases <a href="https://github.com/apache/arrow/issues/48277";
target="_blank" rel="noopener">GH-48277</a>. This rewrite is described in more
detail
+in an <a
href="https://medium.com/@AntoineProuvost/faster-reads-for-apache-parquet-improving-integer-unpacking-f6e21ce49a85";
target="_blank" rel="noopener">accompanying blog post</a>.</p>
+<p>The performance of reading DELTA_BINARY_PACKED-encoded integers has been
improved
+in some favorable cases <a href="https://github.com/apache/arrow/issues/49266";
target="_blank" rel="noopener">GH-49266</a>.</p>
+<h3>Miscellaneous C++ changes</h3>
+<p>We have migrated to C++20 <code>std::span</code>, removing our home-grown
implementation
+in <code>arrow::util::span</code> <a
href="https://github.com/apache/arrow/issues/48588"; target="_blank"
rel="noopener">GH-48588</a>.</p>
+<p>A bunch of previously deprecated APIs have been removed <a
href="https://github.com/apache/arrow/issues/49356"; target="_blank"
rel="noopener">GH-49356</a>.</p>
+<h2>Linux Packaging Notes</h2>
+<p>Added support for Ubuntu 26.04, the next LTS <a
href="https://github.com/apache/arrow/issues/49341"; target="_blank"
rel="noopener">GH-49341</a></p>
+<h2>MATLAB Notes</h2>
+<p>No major notes for this release on MATLAB.</p>
+<h2>Python Notes</h2>
+<h2>Compatibility notes</h2>
+<ul>
+<li>
+<code>pyarrow.gandiva</code> is deprecated and will be removed in a future
version <a href="https://github.com/apache/arrow/issues/49227"; target="_blank"
rel="noopener">GH-49227</a>
+</li>
+</ul>
+<h2>New features</h2>
+<ul>
+<li>Type annotations work is starting to be included (<a
href="https://github.com/apache/arrow/issues/49102"; target="_blank"
rel="noopener">GH-49102</a> and
+<a href="https://github.com/apache/arrow/issues/49452"; target="_blank"
rel="noopener">GH-49452</a>)</li>

href="https://github.com/apache/arrow/issues/32007"; target="_blank"
rel="noopener">GH-32007</a>
+</li>
+<li>Options to control writing of Parquet Bloom filters are added to
<code>parquet.write_table</code> <a
href="https://github.com/apache/arrow/issues/49376"; target="_blank"
rel="noopener">GH-49376</a>
+</li>
+<li>OpenTelemetry is enabled in PyArrow wheels <a

+<li>Scikit-build-core is now used as the PyArrow build system <a
href="https://github.com/apache/arrow/issues/36411"; target="_blank"
rel="noopener">GH-36411</a>
+</li>
+<li>
+<code>UUID</code> objects are now inferred automatically in
<code>pa.scalar()</code> and <code>pa.array()</code> without the need to
+specify the type explicitly <a
href="https://github.com/apache/arrow/issues/48241"; target="_blank"
rel="noopener">GH-48241</a>
+</li>

+<p>The Apache Arrow team is pleased to announce the 24.0.0 release. This
release
+covers over 3 months of development work and includes <a
href="https://github.com/apache/arrow/milestone/72?closed=1";><strong>259
resolved
+issues</strong></a> on <a href="/release/24.0.0.html#contributors"><strong>325
distinct commits</strong></a> from <a
href="/release/24.0.0.html#contributors"><strong>57 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/24.0.0.html#changelog">complete changelog</a>.</p>
+<h2>Community</h2>
+<p>We recently published our <a
href="https://arrow.apache.org/blog/2026/03/19/arrow-2025-highlights/";>Community
Highlights for 2025</a>, check those out.</p>
+<p>Thanks everyone for your contributions and participation in the project!</p>
+<h2>Format Notes</h2>
+<p>We have written a project-wide <a
href="https://arrow.apache.org/docs/dev/format/Security.html";>Security Model</a>
+outlining what users should expect when dealing with Arrow data, especially
coming
+from untrusted sources <a
href="https://github.com/apache/arrow/issues/48868";>GH-48868</a>.</p>
+<h2>Arrow Flight RPC Notes</h2>
+<p>The ODBC driver is still a work-in-progress. The driver now builds on
Linux, but currently no builds are distributed (for any platform) (<a
href="https://github.com/apache/arrow/issues/49463";>GH-49463</a>).</p>
+<p>In C++, we have refactored serialization/deserialization to make low-level
functionality accessible for advanced usage (<a
href="https://github.com/apache/arrow/issues/49548";>GH-49548</a>).</p>
+<h2>C++ Notes</h2>
+<p>In addition to the aforementioned project-wide Security Model, we have
written
+a specific <a
href="https://arrow.apache.org/docs/dev/cpp/security.html";>Security Model for
Arrow C++</a>
+covering more concrete topics such as API usage and parameter validity <a
href="https://github.com/apache/arrow/issues/49274";>GH-49274</a>.</p>
+<h3>Compute</h3>
+<h3>Extension Types</h3>
+<p>The canonical type <a
href="https://arrow.apache.org/docs/format/CanonicalExtensions.html#variable-shape-tensor";>VariableShapeTensor</a>
+was finally implemented <a
href="https://github.com/apache/arrow/issues/38007";>GH-38007</a>.</p>
+<h3>Parquet</h3>
+<p><strong>Breaking change:</strong> The Arrow extension type name for Parquet
Variant columns
+used to be <code>parquet.variant</code> but has been changed to
<code>arrow.parquet.variant</code> <a
href="https://github.com/apache/arrow/issues/49081";>GH-49081</a>.</p>
+<p>While Parquet C++ could only read unencrypted bloom filters, it now supports
+reading encrypted bloom filters as well <a
href="https://github.com/apache/arrow/issues/48334";>GH-48334</a>. In addition,
it can also
+write bloom filters, though only unencrypted <a
href="https://github.com/apache/arrow/issues/34785";>GH-34785</a>.</p>
+<p>An ambitious rewrite of the bit-unpacking utilities and optimizations has
led to
+significant performance improvements on reading some Parquet columns, up to 50%
+faster in some cases <a
href="https://github.com/apache/arrow/issues/48277";>GH-48277</a>. This rewrite
is described in more detail
+in an <a
href="https://medium.com/@AntoineProuvost/faster-reads-for-apache-parquet-improving-integer-unpacking-f6e21ce49a85";>accompanying
blog post</a>.</p>
+<p>The performance of reading DELTA_BINARY_PACKED-encoded integers has been
improved
+in some favorable cases <a
href="https://github.com/apache/arrow/issues/49266";>GH-49266</a>.</p>
+<h3>Miscellaneous C++ changes</h3>
+<p>We have migrated to C++20 <code>std::span</code>, removing our home-grown
implementation
+in <code>arrow::util::span</code> <a
href="https://github.com/apache/arrow/issues/48588";>GH-48588</a>.</p>
+<p>A bunch of previously deprecated APIs have been removed <a
href="https://github.com/apache/arrow/issues/49356";>GH-49356</a>.</p>
+<h2>Linux Packaging Notes</h2>
+<p>Added support for Ubuntu 26.04, the next LTS <a
href="https://github.com/apache/arrow/issues/49341";>GH-49341</a></p>
+<h2>MATLAB Notes</h2>
+<p>No major notes for this release on MATLAB.</p>
+<h2>Python Notes</h2>
+<h2>Compatibility notes</h2>
+<ul>
+<li><code>pyarrow.gandiva</code> is deprecated and will be removed in a future
version <a href="https://github.com/apache/arrow/issues/49227";>GH-49227</a></li>
+</ul>
+<h2>New features</h2>
+<ul>
+<li>Type annotations work is starting to be included (<a
href="https://github.com/apache/arrow/issues/49102";>GH-49102</a> and
+<a href="https://github.com/apache/arrow/issues/49452";>GH-49452</a>)</li>
+<li>Basic arithmetic on arrays and scalars is now supported <a
href="https://github.com/apache/arrow/issues/32007";>GH-32007</a></li>
+<li>Options to control writing of Parquet Bloom filters are added to
<code>parquet.write_table</code> <a
href="https://github.com/apache/arrow/issues/49376";>GH-49376</a></li>
+<li>OpenTelemetry is enabled in PyArrow wheels <a
href="https://github.com/apache/arrow/issues/49382";>GH-49382</a></li>
+<li>AzureFileSystem is now included in the Windows wheels <a
href="https://github.com/apache/arrow/issues/44655";>GH-44655</a></li>
+</ul>
+<h2>Other improvements</h2>
+<ul>
+<li>Scikit-build-core is now used as the PyArrow build system <a
href="https://github.com/apache/arrow/issues/36411";>GH-36411</a></li>
+<li><code>UUID</code> objects are now inferred automatically in
<code>pa.scalar()</code> and <code>pa.array()</code> without the need to
+specify the type explicitly <a
href="https://github.com/apache/arrow/issues/48241";>GH-48241</a></li>
+<li>Constructing an extension array via <code>pa.array()</code> from a list of
extension-type scalars is now supported
+<a href="https://github.com/apache/arrow/issues/48470";>GH-48470</a></li>
