+
+The Apache Arrow team is pleased to announce the version 22 release of
+the Apache Arrow ADBC libraries. This release includes [**14
+resolved issues**][1] from [**16 distinct contributors**][2].
+
+This is a release of the **libraries**, which are at version 22. 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: 1.10.0
+- C#: 0.22.0
+- Java: 0.22.0
+- R: 0.22.0
+- Rust: 0.22.0
+
+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
+
+In the C++ driver manager and packages using it (such as the driver managers
+for Go and Python), now it is possible to open a connection with only a URI
+(the driver name will be assumed to be the URI scheme)
+([#3694](https://github.com/apache/arrow-adbc/pull/3694),
+[#3790](https://github.com/apache/arrow-adbc/pull/3790)).
+
+For Windows users, C++ builds now generate import LIBs so DLLs can be properly
+linked to ([#2858](https://github.com/apache/arrow-adbc/pull/2858)).
+
+The C# Databricks driver has reduced memory usage
+([#3654](https://github.com/apache/arrow-adbc/pull/3654),
+[#3683](https://github.com/apache/arrow-adbc/pull/3683)). Also, token
+exchange was fixed ([#3715](https://github.com/apache/arrow-adbc/pull/3715)),
+and a deadlock was fixed
+([#3756](https://github.com/apache/arrow-adbc/pull/3756)).
+
+The DataFusion driver allows setting the async runtime
+([#3712](https://github.com/apache/arrow-adbc/pull/3712)).
+
+The Arrow Flight SQL driver supports bulk ingestion with compatible servers
+([#3808](https://github.com/apache/arrow-adbc/pull/3808)). The Python package
+also exposes constants for OAuth
+([#3849](https://github.com/apache/arrow-adbc/pull/3849)).
+
+The Go `database/sql` adapter now closes resources properly
+([#3731](https://github.com/apache/arrow-adbc/pull/3731)). All drivers built
+with Go were updated to a newer Go and arrow-go to resolve CVEs reported
+against Go itself (although we believe they do not affect the drivers) and to
+resolve a crash when used with Polars
+([#3758](https://github.com/apache/arrow-adbc/pull/3758)).
+
+The PostgreSQL driver supports setting the transaction isolation level
+([#3760](https://github.com/apache/arrow-adbc/pull/3760)), and a bug with the
+GetObjects filter options was fixed
+([#3855](https://github.com/apache/arrow-adbc/pull/3855)).
+
+The Python driver manager will now close unclosed cursors for you when a
+connection is closed
+([#3810](https://github.com/apache/arrow-adbc/pull/3810)).
+
+Driver shared libraries built with Rust will now catch panics and error
+gracefully instead of terminating the entire process (although we do not
+currently distribute any driver libraries built this way)
+([#3819](https://github.com/apache/arrow-adbc/pull/3819)). Also, the Rust
+driver manager will no longer `dlclose` driver libraries as drivers built with
+Go would hang if this was done on some platforms
+([#3844](https://github.com/apache/arrow-adbc/pull/3844)).
+
+The SQLite driver supports more info keys
+([#3843](https://github.com/apache/arrow-adbc/pull/3843)).

+## Roadmap
+
+We are working on the next revision of the API standard. After some
+discussion, we will likely put aside async APIs to focus on addressing other
+API gaps that users have reported. However, we may still define
+langauge-specific async APIs for ecosystems that expect them (like Rust).
+
+## 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].
