We're currently running a large multi-site installation with HyperDB and WP 3.3.2. We'd like to plan our upgrade to 3.4.1 soon but it seems HyperDB does not yet support this version.
Is this something in the works? Are there specific concerns about it? Before we start making the effort to do pre-production testing & migration we'd like to know as much as possible about what to expect.
