target="_blank" rel="noopener">Changelog</a>
+for a detailed list of contributions to this release.</p>
+<h2>Features</h2>
+<h3>String Views By Buffer</h3>
+<p>The C library in general supports two methods for producing or consuming
arrays: most
+users use the builder pattern (e.g., <code>ArrowArrayAppendString()</code>);
however, the "build
+by buffer" pattern can be effective when using nanoarrow with a higher level
runtime
+like C++, Rust, Python, or R, all of which have mechanisms to build buffers
already.
+The C library supports this with <code>ArrowArraySetBuffer()</code>; however,
there was no way
+to reserve and/or set variadic buffers for string view arrays. In nanoarrow
0.8.0,
+the array builder API fully supports both mechanisms for building string view
arrays.</p>
+<h3>LZ4 Decompression Support</h3>
+<p>The Arrow IPC reader included in the nanoarrow C library supports most
features
+of the Arrow IPC format; however, decompression support for the LZ4 codec was
missing
+which made the library and its bindings unusable for some common use cases. In
0.8.0,
+decompression for the LZ4 codec was added to the C library.</p>
+<p>Users of the C library will need to configure CMake with
<code>-DNANOARROW_IPC_WITH_LZ4=ON</code>
+and <code>-DNANOARROW_IPC=ON</code> to use CMake-resolved LZ4; however, client
libraries
+can also use an existing ZSTD or LZ4 implementation using callbacks just like
in 0.7.0.</p>
+<h3>nanoarrow on Conan</h3>
+<p>The nanoarrow C library can now be installed using the
+<a href="https://conan.io/center/recipes/nanoarrow"; target="_blank"
rel="noopener">Conan</a> C/C++ Package Manager!
+CMake projects can now use <code>find_package(nanoarrow)</code> when using a

<h2>4. Conclusion</h2>
<p>The Parquet reader in <code>arrow-rs</code> isn't just a humble file
reader—it's a <strong>mini query engine</strong> in disguise. We've baked in
high-end features like predicate pushdown and late materialization. The reader
reads only what's needed and decodes only what's necessary, saving resources
while maintaining correctness. Previously, these features were restricted to
proprietary or tightly integrated systems. Now, thanks to the community's
efforts, <code>arrow-rs</code> bring [...]

-<p>The Apache Arrow team is pleased to announce the version 21 release of
-the Apache Arrow ADBC libraries. This release includes <a
href="https://github.com/apache/arrow-adbc/milestone/25";><strong>30
-resolved issues</strong></a> from <a href="#contributors"><strong>23 distinct
contributors</strong></a>.</p>
-<p>This is a release of the <strong>libraries</strong>, which are at version
21. The
-<a
href="https://arrow.apache.org/adbc/21/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: 1.9.0</li>
-<li>C#: 0.21.0</li>
-<li>Java: 0.21.0</li>
-<li>R: 0.21.0</li>
-<li>Rust: 0.21.0</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-21/CHANGELOG.md";>complete
changelog</a>.</p>
-<h2>Release Highlights</h2>
-<p>Language bindings:</p>
-<ul>
-<li>The driver manager reports better errors when it fails to find a driver
(<a href="https://github.com/apache/arrow-adbc/pull/3646";>#3646</a>).</li>
-<li>The Python driver manager now searches for manifests in the proper
location when inside a Python virtual environment (<a
href="https://github.com/apache/arrow-adbc/pull/3490";>#3490</a>).</li>
-<li>Added convenience methods to the driver manager on top of the standard
DBAPI-2.0/PEP249 APIs (<a
href="https://github.com/apache/arrow-adbc/pull/3539";>#3539</a>).</li>
-<li>The signature for <code>connect</code> has been simplified, so you can
connect without having to repeat the driver name or specify explicit keyword
arguments depending on the driver (<a
href="https://github.com/apache/arrow-adbc/pull/3537";>#3537</a>).</li>
-<li>Support for Python 3.9 has been dropped (<a
href="https://github.com/apache/arrow-adbc/pull/3573";>#3573</a>, <a
href="https://github.com/apache/arrow-adbc/pull/3663";>#3663</a>).</li>
-<li>Support for Python 3.14 (including the free-threading variant) has been
added (<a href="https://github.com/apache/arrow-adbc/pull/3575";>#3575</a>, <a
href="https://github.com/apache/arrow-adbc/pull/3620";>#3620</a>, <a
href="https://github.com/apache/arrow-adbc/pull/3663";>#3663</a>).</li>
-<li>The R bindings now support <code>replace</code> and
<code>create_append</code> ingest modes.</li>
-</ul>
-<p>Drivers:</p>
-<ul>
-<li>The Go BigQuery driver now supports service account impersonation (<a
href="https://github.com/apache/arrow-adbc/pull/3488";>#3488</a>) and setting a
quota project (<a
href="https://github.com/apache/arrow-adbc/pull/3622";>#3622</a>).</li>
-<li>The Go BigQuery driver now returns more detailed type metadata in result
sets (<a href="https://github.com/apache/arrow-adbc/pull/3604";>#3604</a>).</li>
-<li>The C# BigQuery driver allows setting a location (<a
href="https://github.com/apache/arrow-adbc/pull/3494";>#3494</a>).</li>
-<li>The C# Databricks driver adjusted default settings to make small queries
faster (<a
href="https://github.com/apache/arrow-adbc/pull/3489";>#3489</a>).</li>
-<li>Memory usage of the C# Databricks driver was improved (<a
href="https://github.com/apache/arrow-adbc/pull/3652";>#3652</a>, <a
href="https://github.com/apache/arrow-adbc/pull/3656";>#3656</a>).</li>
-<li>All C# HiveServer2-based drivers (Hive, Impala, Spark, Databricks) throw
Unauthorized exceptions when appropriate (<a
href="https://github.com/apache/arrow-adbc/pull/3551";>#3551</a>).</li>
-<li>JNI bindings to the C++ driver manager are now released, making it
possible to use non-Java drivers from a Java application (in a very limited
fashion) (<a href="https://github.com/apache/arrow-adbc/pull/3429";>#3429</a>).
Binary artifacts are available for amd64/arm64 Linux, arm64 macOS, and amd64
Windows.</li>
-<li>The PostgreSQL driver can now return the schema of any bind parameters in
a prepared query
([#3579[(https://github.com/apache/arrow-adbc/pull/3579)]]).</li>
-<li>The PostgreSQL driver properly batches result sets with large
string/binary values now (<a
href="https://github.com/apache/arrow-adbc/pull/3616";>#3616</a>).</li>
-<li>The Snowflake driver now returns float64 for numeric columns when
use_high_precision is false and scale is nonzero (<a
href="https://github.com/apache/arrow-adbc/pull/3295";>#3295</a>). (Previously
it incorrectly truncated to int64.)</li>
-<li>Added an option to disable the "vectorized" scanner when
ingesting data into Snowflake, which sometimes appeared to cause performance
issues (<a
href="https://github.com/apache/arrow-adbc/pull/3555";>#3555</a>).</li>
-</ul>
-<p>Packaging:</p>
-<ul>
-<li>Added AlmaLinux 10 (<a
href="https://github.com/apache/arrow-adbc/pull/3514";>#3514</a>).</li>
-<li>Added Debian Trixie (<a
href="https://github.com/apache/arrow-adbc/pull/3513";>#3513</a>).</li>
-</ul>
