Yesterday IBM release the new release of IBM Notes Traveler including the following fixes:
IBM Traveler 18.104.22.168 includes a database schema update for MS SQL Server deployments. It is only necessary to run verifyIndexes.sql to update the schema to latest level. Otherwise no action is required unless upgrading from a version prior to 22.214.171.124. If you use auto schema updates (default behavior) there is no action required.
The upgrade is available on IBM Fix Central.
