The Apache Arrow team is pleased to announce the 0.6.0 release of the Apache Arrow ADBC libraries. This covers includes 46 resolved issues from 9 distinct contributors.
This is a release of the libraries, which are at version 0.6.0. The API specification is versioned separately and is at version 1.0.0. (The API version will be updated to 1.1.0 in the coming release.)
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.
Release Highlights
The PostgreSQL and SQLite drivers have better type support. The PostgreSQL driver will also chunk its output now instead of always delivering a single record batch. The Snowflake driver no longer requires a URI to connect. The Python driver manager and Flight SQL driver deliver more concise error messages, with less fluff around the actual error message delivered by the database.
A critical bugfix for all Go-based drivers (Flight SQL and Snowflake) is included. This fixes panics caused by uninitialized memory in C Data Interface structures appearing to the garbage collector as (invalid) pointers to Go memory. For details, see issue 729.
While C# is not yet included in this release, the library is now more compatible with .NET 4.

Roadmap
The 1.1.0 revision of the ADBC API was accepted, but is not included in this release. It will be released as ADBC 0.7.0.
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.
