+
+The Apache Arrow team is pleased to announce the version 20 release of
+the Apache Arrow ADBC libraries. This release includes [**44
+resolved issues**][1] from [**29 distinct contributors**][2].
+
+This is a release of the **libraries**, which are at version 20. 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: 1.8.0
+- C#: 0.20.0
+- Java: 0.20.0
+- R: 0.20.0
+- Rust: 0.20.0
+
+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
+
+Driver managers now support loading driver manifests. To learn more about
+this feature, please see the [documentation][driver-manifests].
+
+The Rust crates were reorganized. **This is a breaking change.** Now,
+FFI-related code is part of `adbc_ffi` and the driver manager is part of
+`adbc_driver_manager`. Previously these were features of a single crate
+`adbc_core`, which now only contains API definitions
+([#3381](https://github.com/apache/arrow-adbc/pull/3381),
+[#3197](https://github.com/apache/arrow-adbc/pull/3197)). Also, some enums
+are no longer marked as `#[non_exhaustive]`
+([#3245](https://github.com/apache/arrow-adbc/pull/3245)).
+
+The Java JNI bindings support a few more features
+([#3373](https://github.com/apache/arrow-adbc/pull/3373),
+[#3372](https://github.com/apache/arrow-adbc/pull/3372),
+[#3370](https://github.com/apache/arrow-adbc/pull/3370),
+[#3348](https://github.com/apache/arrow-adbc/pull/3348)).
+
+The BigQuery driver properly uses microsecond timestamps
+([#3364](https://github.com/apache/arrow-adbc/pull/3364)), has an improved
+error message if your user account lacks the proper permissions
+([#3297](https://github.com/apache/arrow-adbc/pull/3297)), properly handles
+nested data ([#3240](https://github.com/apache/arrow-adbc/pull/3240)), and
+supports service account impersonation
+([#3174](https://github.com/apache/arrow-adbc/pull/3174)). The C#
+Databricks/HiveServer2 Thrift-protocol drivers continues to expand their
+featureset, such as support for cancelling statements, token exchange, and
+better tracing ([#3304](https://github.com/apache/arrow-adbc/pull/3304),
+[#3302](https://github.com/apache/arrow-adbc/pull/3302),
+[#3301](https://github.com/apache/arrow-adbc/pull/3301),
+[#3224](https://github.com/apache/arrow-adbc/pull/3224),
+[#3218](https://github.com/apache/arrow-adbc/pull/3218),
+[#3192](https://github.com/apache/arrow-adbc/pull/3192),
+[#3177](https://github.com/apache/arrow-adbc/pull/3177),
+[#3137](https://github.com/apache/arrow-adbc/pull/3137),
+[#3127](https://github.com/apache/arrow-adbc/pull/3127)). The PostgreSQL
+driver will properly bind `arrow.json` extension arrays as JSON parameters
+([#3333](https://github.com/apache/arrow-adbc/pull/3333)). The Snowflake
+driver supports more authentication methods
+([#3366](https://github.com/apache/arrow-adbc/pull/3366)). The SQLite driver
+can bind parameters by name instead of position
+([#3362](https://github.com/apache/arrow-adbc/pull/3362)).
+
+The C# library has been upgraded to .NET 8
+([#3120](https://github.com/apache/arrow-adbc/pull/3120)).
+
+GLib has more bindings to ADBC functions
+([#3118](https://github.com/apache/arrow-adbc/pull/3118)).
+
+The Go library has some experimental helpers to simplify getting driver
+metadata ([#3239](https://github.com/apache/arrow-adbc/pull/3239)) and
+ingesting Arrow data
+([#3150](https://github.com/apache/arrow-adbc/pull/3150)). The `database/sql`
+adapter handles `time.Time` values for bind parameters now
+([#3109](https://github.com/apache/arrow-adbc/pull/3109)). Drivers will
+forward SQLSTATE and other error metadata across the FFI boundary
+([#2801](https://github.com/apache/arrow-adbc/pull/2801)).
