dhtmlx_std_full_web_skin.zip missing from dhtmlxSuite v4

Hi All,
I’m leveraging the Your First App tutorial at http://docs.dhtmlx.com/tutorials__first_app__step1.html and have found that the file dhtmlx_std_full_web_skin.zip does not appear to be included in version 4 of the standard edition of DHTMLX Suite whose download link is http://www.dhtmlx.com/x/download/regular/dhtmlxSuite.zip.
Can someone shed some light on this?
