+<p>The Apache Arrow team is pleased to announce the version 20 release of
+the Apache Arrow ADBC libraries. This release includes <a
href="https://github.com/apache/arrow-adbc/milestone/24"; target="_blank"
rel="noopener"><strong>44
+resolved issues</strong></a> from <a href="#contributors"><strong>29 distinct
contributors</strong></a>.</p>
+<p>This is a release of the <strong>libraries</strong>, which are at version
20. The
+<a
href="https://arrow.apache.org/adbc/20/format/specification.html";><strong>API
specification</strong></a> is versioned separately and is at
+version 1.1.0.</p>
+<p>The subcomponents are versioned independently:</p>
+<ul>
+<li>C/C++/GLib/Go/Python/Ruby: 1.8.0</li>
+<li>C#: 0.20.0</li>
+<li>Java: 0.20.0</li>
+<li>R: 0.20.0</li>
+<li>Rust: 0.20.0</li>
+</ul>
+<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="https://github.com/apache/arrow-adbc/blob/apache-arrow-adbc-20/CHANGELOG.md";
target="_blank" rel="noopener">complete changelog</a>.</p>
+<h2>Release Highlights</h2>
+<p>Driver managers now support loading driver manifests. To learn more about
+this feature, please see the <a
href="https://arrow.apache.org/adbc/current/format/driver_manifests.html#driver-manifests";>documentation</a>.</p>
+<p>The Rust crates were reorganized. <strong>This is a breaking
change.</strong> Now,
+FFI-related code is part of <code>adbc_ffi</code> and the driver manager is
part of
+<code>adbc_driver_manager</code>. Previously these were features of a single
crate
+<code>adbc_core</code>, which now only contains API definitions
+(<a href="https://github.com/apache/arrow-adbc/pull/3381"; target="_blank"
rel="noopener">#3381</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3197"; target="_blank"
rel="noopener">#3197</a>). Also, some enums
+are no longer marked as <code>#[non_exhaustive]</code>
+(<a href="https://github.com/apache/arrow-adbc/pull/3245"; target="_blank"
rel="noopener">#3245</a>).</p>
+<p>The Java JNI bindings support a few more features
+(<a href="https://github.com/apache/arrow-adbc/pull/3373"; target="_blank"
rel="noopener">#3373</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3372"; target="_blank"
rel="noopener">#3372</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3370"; target="_blank"
rel="noopener">#3370</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3348"; target="_blank"
rel="noopener">#3348</a>).</p>
+<p>The BigQuery driver properly uses microsecond timestamps
+(<a href="https://github.com/apache/arrow-adbc/pull/3364"; target="_blank"
rel="noopener">#3364</a>), has an improved
+error message if your user account lacks the proper permissions
+(<a href="https://github.com/apache/arrow-adbc/pull/3297"; target="_blank"
rel="noopener">#3297</a>), properly handles
+nested data (<a href="https://github.com/apache/arrow-adbc/pull/3240";
target="_blank" rel="noopener">#3240</a>), and
+supports service account impersonation
+(<a href="https://github.com/apache/arrow-adbc/pull/3174"; target="_blank"
rel="noopener">#3174</a>). The C#
+Databricks/HiveServer2 Thrift-protocol drivers continues to expand their
+featureset, such as support for cancelling statements, token exchange, and
+better tracing (<a href="https://github.com/apache/arrow-adbc/pull/3304";
target="_blank" rel="noopener">#3304</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3302"; target="_blank"
rel="noopener">#3302</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3301"; target="_blank"
rel="noopener">#3301</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3224"; target="_blank"
rel="noopener">#3224</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3218"; target="_blank"
rel="noopener">#3218</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3192"; target="_blank"
rel="noopener">#3192</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3177"; target="_blank"
rel="noopener">#3177</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3137"; target="_blank"
rel="noopener">#3137</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3127"; target="_blank"
rel="noopener">#3127</a>). The PostgreSQL
+driver will properly bind <code>arrow.json</code> extension arrays as JSON
parameters
+(<a href="https://github.com/apache/arrow-adbc/pull/3333"; target="_blank"
rel="noopener">#3333</a>). The Snowflake
+driver supports more authentication methods
+(<a href="https://github.com/apache/arrow-adbc/pull/3366"; target="_blank"
rel="noopener">#3366</a>). The SQLite driver
+can bind parameters by name instead of position
+(<a href="https://github.com/apache/arrow-adbc/pull/3362"; target="_blank"
rel="noopener">#3362</a>).</p>
+<p>The C# library has been upgraded to .NET 8
+(<a href="https://github.com/apache/arrow-adbc/pull/3120"; target="_blank"
rel="noopener">#3120</a>).</p>
+<p>GLib has more bindings to ADBC functions
+(<a href="https://github.com/apache/arrow-adbc/pull/3118"; target="_blank"
rel="noopener">#3118</a>).</p>
+<p>The Go library has some experimental helpers to simplify getting driver
+metadata (<a href="https://github.com/apache/arrow-adbc/pull/3239";
target="_blank" rel="noopener">#3239</a>) and
+ingesting Arrow data
+(<a href="https://github.com/apache/arrow-adbc/pull/3150"; target="_blank"
rel="noopener">#3150</a>). The <code>database/sql</code>
+adapter handles <code>time.Time</code> values for bind parameters now
+(<a href="https://github.com/apache/arrow-adbc/pull/3109"; target="_blank"
rel="noopener">#3109</a>). Drivers will
+forward SQLSTATE and other error metadata across the FFI boundary
+(<a href="https://github.com/apache/arrow-adbc/pull/2801"; target="_blank"
rel="noopener">#2801</a>).</p>

+<p>The Apache Arrow team is pleased to announce the version 20 release of
+the Apache Arrow ADBC libraries. This release includes <a
href="https://github.com/apache/arrow-adbc/milestone/24";><strong>44
+resolved issues</strong></a> from <a href="#contributors"><strong>29 distinct
contributors</strong></a>.</p>
+<p>This is a release of the <strong>libraries</strong>, which are at version
20. The
+<a
href="https://arrow.apache.org/adbc/20/format/specification.html";><strong>API
specification</strong></a> is versioned separately and is at
+version 1.1.0.</p>
+<p>The subcomponents are versioned independently:</p>
+<ul>
+<li>C/C++/GLib/Go/Python/Ruby: 1.8.0</li>
+<li>C#: 0.20.0</li>
+<li>Java: 0.20.0</li>
+<li>R: 0.20.0</li>
+<li>Rust: 0.20.0</li>
+</ul>
+<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="https://github.com/apache/arrow-adbc/blob/apache-arrow-adbc-20/CHANGELOG.md";>complete
changelog</a>.</p>
+<h2>Release Highlights</h2>
+<p>Driver managers now support loading driver manifests. To learn more about
+this feature, please see the <a
href="https://arrow.apache.org/adbc/current/format/driver_manifests.html#driver-manifests";>documentation</a>.</p>
+<p>The Rust crates were reorganized. <strong>This is a breaking
change.</strong> Now,
+FFI-related code is part of <code>adbc_ffi</code> and the driver manager is
part of
+<code>adbc_driver_manager</code>. Previously these were features of a single
crate
+<code>adbc_core</code>, which now only contains API definitions
+(<a href="https://github.com/apache/arrow-adbc/pull/3381";>#3381</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3197";>#3197</a>). Also,
some enums
+are no longer marked as <code>#[non_exhaustive]</code>
+(<a href="https://github.com/apache/arrow-adbc/pull/3245";>#3245</a>).</p>
+<p>The Java JNI bindings support a few more features
+(<a href="https://github.com/apache/arrow-adbc/pull/3373";>#3373</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3372";>#3372</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3370";>#3370</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3348";>#3348</a>).</p>
+<p>The BigQuery driver properly uses microsecond timestamps
+(<a href="https://github.com/apache/arrow-adbc/pull/3364";>#3364</a>), has an
improved
+error message if your user account lacks the proper permissions
+(<a href="https://github.com/apache/arrow-adbc/pull/3297";>#3297</a>), properly
handles
+nested data (<a
href="https://github.com/apache/arrow-adbc/pull/3240";>#3240</a>), and
+supports service account impersonation
+(<a href="https://github.com/apache/arrow-adbc/pull/3174";>#3174</a>). The C#
+Databricks/HiveServer2 Thrift-protocol drivers continues to expand their
+featureset, such as support for cancelling statements, token exchange, and
+better tracing (<a
href="https://github.com/apache/arrow-adbc/pull/3304";>#3304</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3302";>#3302</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3301";>#3301</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3224";>#3224</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3218";>#3218</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3192";>#3192</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3177";>#3177</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3137";>#3137</a>,
+<a href="https://github.com/apache/arrow-adbc/pull/3127";>#3127</a>). The
PostgreSQL
+driver will properly bind <code>arrow.json</code> extension arrays as JSON
parameters
+(<a href="https://github.com/apache/arrow-adbc/pull/3333";>#3333</a>). The
Snowflake
+driver supports more authentication methods
+(<a href="https://github.com/apache/arrow-adbc/pull/3366";>#3366</a>). The
SQLite driver
+can bind parameters by name instead of position
+(<a href="https://github.com/apache/arrow-adbc/pull/3362";>#3362</a>).</p>
+<p>The C# library has been upgraded to .NET 8
+(<a href="https://github.com/apache/arrow-adbc/pull/3120";>#3120</a>).</p>
+<p>GLib has more bindings to ADBC functions
+(<a href="https://github.com/apache/arrow-adbc/pull/3118";>#3118</a>).</p>
+<p>The Go library has some experimental helpers to simplify getting driver
+metadata (<a href="https://github.com/apache/arrow-adbc/pull/3239";>#3239</a>)
and
+ingesting Arrow data
+(<a href="https://github.com/apache/arrow-adbc/pull/3150";>#3150</a>). The
<code>database/sql</code>
+adapter handles <code>time.Time</code> values for bind parameters now
+(<a href="https://github.com/apache/arrow-adbc/pull/3109";>#3109</a>). Drivers
will
+forward SQLSTATE and other error metadata across the FFI boundary
+(<a href="https://github.com/apache/arrow-adbc/pull/2801";>#2801</a>).</p>

-objects</a>.
-This change is the first step in eventually deprecating the
<code>arrow_binary</code>
-class in favor of the <code>blob</code> class in the
-<a href="https://cran.r-project.org/package=blob";><code>blob</code></a>
package (See
