A Lab release is a preview of one or more features under development which have normally not been integrated into TRUNK yet. Lab release features are not part of the last DMR (development milestone release). Lab releases are created when the MySQL community voices interest in evaluating early work, and they are snapshots of the feature tree at a given point in time. Lab releases can have beta quality, or they can be available only on a limited set of platforms, or documentation can not be available. Finally, there is no guarantee that the features in a lab release will appear in future DMR or GA releases. Lab releases can be found at labs.mysql.com.
