+
+The Apache Arrow team is pleased to announce the 0.4.0 release of
+the Apache Arrow ADBC libraries. This covers includes [**47
+resolved issues**][1] from [**8 distinct contributors**][2].
+
+This is a release of the **libraries**, which are at version
+0.4.0. The **API specification** is versioned separately and is
+at version 1.0.0.
+
+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 Go-based driver for [Snowflake](https://www.snowflake.com/en/) was added,
along with bindings for Python and R.
+
+The PostgreSQL driver now has much better support for different types, and
properly handles NULL values.
+It now also implements `AdbcConnectionGetTableSchema`.
+All C/C++ components have been consolidated into a single build project,
simplifying integration with IDEs.
+
+Several `ArrowBuf` leaks in the Java libraries have been fixed, along with
miscellaneous bugs in the JDBC adapter.
+There was breaking change in the Java libraries: static driver instances were
removed, as this was prone to the aformentioned leaks.
+Instead, `AdbcDriver` instances can now be created with a `BufferAllocator`,
giving the application control over allocations.
+
+The Python, GLib, and Ruby bindings expose more of the API functions.
+The Python bindings are now tested against the [polars](https://www.pola.rs/)
dataframe project, which has experimental integration with ADBC.
+The release process was fixed to properly upload the Windows Python wheels.
+The R bindings now include packages for the PostgreSQL driver.
+
+There is a known issue with the Snowflake driver: it will not build on
non-x86_64 (AMD64) platforms, including Linux/macOS arm64/aarch64.
+This has already been fixed for the next release.
