ElevateDB 2.28 Build 3 is now available for download. If you're an existing customer, then you should be receiving an email shortly with download instructions.
This build contains two important bug fixes, which are detailed here.
One of the two bug fixes is to fix an issue with the new I/O buffering feature, so it is now safe to resume using the I/O buffering in production. For more information, please see the Buffering and Caching topic in the SQL manual.
