How are managed namespace versions in DTS Editor?

I've created one namespace but I don't know how to set its version in the DTS Editor.

Thanks

Click on the Namespace Editor option in the Tools menu. Select your desired Thesaurus Namespace and click "Publish". DTS will request the name of the version to be created. Publishing will finalize (create) the version and add a new Working version (published versions are read-only). For details on the publishing operation, see the DTS Versioning Guide from the documention page.
