+The Apache Arrow team is pleased to announce the version 25 release of
+the Apache Arrow ADBC libraries. This release includes [**56
+resolved issues**][1] and [**142 merged pull requests**][2] from
+[**25 distinct contributors**](#contributors).
+
+This is a release of the **libraries**, which are at version 25. The
+[**API specification**][specification] is versioned separately and is at
+version 1.1.0.
+
+The subcomponents are versioned independently:
+
+- C/C++/GLib/Go/Python/Ruby: 1.13.0
+- C#: 1.0.0 (core), 0.25.0 (drivers)
+- Java: 0.25.0
+- JavaScript: 0.25.0
+- R: 0.25.0
+- Rust: 0.25.0
+
+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 [complete changelog][3].
+
+## Release Highlights
+
+We now have a
[logo](https://arrow.apache.org/adbc/current/visual_identity.html) for ADBC
([#4870](https://github.com/apache/arrow-adbc/pull/4870)).
+
+We now provide some support for Windows-on-ARM, including Node.js packages,
Python wheels, and Java JNI JARs.
+
+The C++ libraries now require C++20
([#4610](https://github.com/apache/arrow-adbc/pull/4610)).
+
+The C# core libraries are now version 1.0 and support ADBC 1.1 APIs
([#4923](https://github.com/apache/arrow-adbc/pull/4923) and many more). The
ADO.NET client now supports canonical extension types like UUID and Variant
([#4919](https://github.com/apache/arrow-adbc/pull/4919)).
+
+The Go libraries have been split: the core libraries and the drivers are now
separate Go modules. This was done to stop driver-specific dependencies (and
their associated CVEs) from leaking into _all_ Go projects using ADBC, but is a
breaking change for those who were directly depending on Go drivers from a Go
project ([#4754](https://github.com/apache/arrow-adbc/pull/4754)).
+
+We now distribute Python wheels for Python 3.15
([#4879](https://github.com/apache/arrow-adbc/pull/4879)). Python 3.10 went EOL
before release, so it was dropped
([#4859](https://github.com/apache/arrow-adbc/pull/4859)).
+
+The Rust libraries made several changes focused on reducing unsafe/undefined
behavior, but note that certain low-level (but public) APIs had breaking
changes as a result, and that exported drivers now require `Send`
([#4876](https://github.com/apache/arrow-adbc/pull/4876),
[#4875](https://github.com/apache/arrow-adbc/pull/4875),
[#4874](https://github.com/apache/arrow-adbc/pull/4874),
[#4873](https://github.com/apache/arrow-adbc/pull/4873),
[#4872](https://github.com/apache/arrow-adbc/pu [...]
+
+The Flight SQL driver now supports the new `is_update` field if reported by
the server ([#4161](https://github.com/apache/arrow-adbc/pull/4161)).
+
+Several fixes were made to the PostgreSQL driver; temporary tables are now
shown in GetObjects, and ingesting TIME types is now supported
([#4850](https://github.com/apache/arrow-adbc/pull/4850),
[#4848](https://github.com/apache/arrow-adbc/pull/4848),
[#4824](https://github.com/apache/arrow-adbc/pull/4824),
[#4819](https://github.com/apache/arrow-adbc/pull/4819),
[#4798](https://github.com/apache/arrow-adbc/pull/4798),
[#4710](https://github.com/apache/arrow-adbc/pull/4710)). `POSTGRESQ [...]
+
+Several fixes were made to the SQLite driver to bring it more on par with
other drivers ([#4845](https://github.com/apache/arrow-adbc/pull/4845),
[#4843](https://github.com/apache/arrow-adbc/pull/4843),
[#4842](https://github.com/apache/arrow-adbc/pull/4842),
[#4841](https://github.com/apache/arrow-adbc/pull/4841),
[#4826](https://github.com/apache/arrow-adbc/pull/4826)).

+## Roadmap
+
+We are working on the next revision of the API standard, focusing on missing
+features (primarily metadata/catalog data). We welcome anyone interested in
+contributing. Current progress can be found in the [1.2.0 specification
+milestone](https://github.com/apache/arrow-adbc/milestone/9).
+
+## Getting Involved
+
+We welcome questions and contributions from all interested. Issues
+can be filed on [GitHub][4], and questions can be directed to GitHub
+or the [Arrow mailing lists][5].
