We just reposted another cubeSQL 4.0b6 build due to a last minute bug fixed.
The difference between the new version and the old one is just in the core server and the bug fixed is related to the way the new plugin binds data into the server (so only db.InsertRecord and rs.Update are affected). As a side effect this fixes also the “Incomplete SQL statement” error message that some user reported few days ago.

The new build can be downloaded from:
