Quick question re. jar-files in 4.1 vs old

Hi, just upgrading from 3.1 to 4.1 and i noticed something different re. the jar-files.

In my current setup, i have maven dependencies to both smartgwt.jar and smartgwtpro.jar

However, i've just setup the new maven tools in 4.1 and i noticed that those only download the pro-jar, there is no "regular".

And in the download-zip i got from your site, there is a jar, but it's empty.

I take it that it's obsolete, just posting for confirmation that i understood it correctly...
