[Monetdb-developers] new release

Some problems have been found in the X.18.0 release that we've created in both SQL and XQuery. Because of that we're planning to do a minor release of just those two packages on Tuesday. In SQL, the error was a crash of the server when adding a foreign key to an existing table. In XQuery, the problem was mainly a performance issue (and missing pftijah functionality in the Windows builds). -- Sjoerd Mullender
