+
+The Apache Arrow team is pleased to announce the 14 release of
+the Apache Arrow ADBC libraries. This covers includes [**27
+resolved issues**][1] from [**12 distinct contributors**][2].
+
+This is a release of the **libraries**, which are at version
+14.  The **API specification** is versioned separately and is
+at version 1.1.0.
+
+The subcomponents are versioned independently:
+
+- C/C++/GLib/Go/Python/Ruby: 1.2.0
+- C#: 0.14.0
+- Java: 0.14.0
+- R: 0.14.0
+- Rust: 0.14.0
+
+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
+
+A new driver for Google BigQuery is now available in source form and will be available from conda-forge, however, Python wheels will not be available until the next release.  Thanks to [Cocoa Xu](https://github.com/cocoa-xu) for the major effort!
+
+The C/C++ implementation now uses `arrow-adbc/adbc.h` as its include path to avoid polluting the `include` directory.  For now, `adbc.h` is still installed for backwards compatibility but we recommend updating include paths.
+
+The C# ADO.NET bindings now support bind parameters.
+
+The Rust library is now [uploaded to crates.io](https://crates.io/crates/adbc_core).
+
+The PostgreSQL driver now properly handles reading JSONB columns and ingestion of list/large list columns.  It also finally properly supports bind parameters in prepared statements and can handle multiple statements in the same string.
+
+We discovered a [performance regression](https://github.com/golang/go/issues/68587) in recent versions of Go when making FFI calls from the main thread.  Unfortunately, this affects the Arrow Flight SQL, BigQuery, and Snowflake driver implementations.  Python wheels are not affected as we are still building with an older version of Go.  However, if you are building the driver yourself or using the conda-forge package, you may run into this.  Mitigations include making fewer FFI calls if possible (e.g., reuse a single connection or cursor instead of creating new ones), or using a different thread than the main thread.

+## Roadmap
+
+There is some discussion on a potential second revision of ADBC to include more missing functionality and asynchronous API support.  For more, see the [milestone](https://github.com/apache/arrow-adbc/milestone/8) and the [async discussion](https://github.com/apache/arrow-adbc/issues/811)/[proposed C Data Interface API](https://github.com/apache/arrow/pull/43632).
