+
+The Apache Arrow team is pleased to announce the 0.7.0 release of
+the Apache Arrow ADBC libraries. This covers includes [**50
+resolved issues**][1] from [**8 distinct contributors**][2].
+
+This is a release of the **libraries**, which are at version
+0.7.0.  The **API specification** is versioned separately and is
+at version 1.1.0.
+
+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
+
+This is the first release to implement version 1.1.0 of the ADBC API
+specification.  The [documentation][api-changelog] has a fuller
+overview of new features, but in brief:
+
+- More common options and info keys were added, and clients can now
+  retrieve option values instead of only being able to set them.
+- Connections/statements can be cancelled.
+- Drivers can add arbitrary metadata to errors.  For example, the
+  Flight SQL driver exposes gRPC status details, and the PostgreSQL
+  driver provides PostgreSQL-specific error fields.
+- Miscellaneous other APIs to cover specific feature gaps (e.g.
+  getting/setting the 'active' catalog and schema).
+
+The PostgreSQL and SQLite drivers support ingesting Arrow data into
+temporary tables, and targeting a table in a particular namespace.
+Also, they handle quoting of table/column names in bulk ingestion
+better.  Both drivers also support more Arrow types when executing
+queries and ingesting data.
+
+The FlightSQL driver supports basic logging via configuration in
+Go code or via an environment variable when built as a shared library
+(for Python/R).
+
+The Snowflake driver properly handles `TIME` fields.
+
+The minimum Go version was bumped to 1.19 (in line with the next
+release of the Arrow Go libraries).
+
+R drivers expose functions to quote/escape names and strings for the
+specific backend.
+
+The Python DBAPI layer wraps Arrow record batch readers to raise
+ADBC exceptions if the driver provides error metadata (see above).

+
+## Roadmap
+
+Work continues on improving the existing drivers in terms of supported
+Arrow/database types, performance, and so on.
+
+For Java, the minimum JDK version may be raised from JDK 8 to 11 or 17,
+a move that the Arrow Java libraries are also considering.
+
+There are currently no plans for a second API revision. As work progresses
+on asynchronous and device-aware APIs in the Arrow ecosystem, ADBC will
+eventually be updated to support any new APIs.
+
+## 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].
