Work for the proposed 1.1.0 API revision is progressing on a branch, with several API proposals merged in and others awaiting review. They will then receive prototype implementations before being submitted for review/voting. This is not currently targeting any release of the ADBC libraries, although we hope to wrap up this effort in the next few months.

A milestone has been created to explore asynchronous APIs, which have been requested for a while now.
