Netscape 4 addressed the problem of Netscape Navigator being used as both the name of the suite and the browser contained within it by renaming the suite to Netscape Communicator.[4] After releasing five preview releases from 1996–1997, Netscape Corp. released the final version of Netscape Communicator in June 1997. This new version, more or less based on Netscape Navigator 3 Code, updated and added new features (such as support of certain CSS1 elements, minimal dynamic font support and the proprietary object element). The new suite was successful, despite increasing competition from Internet Explorer 4.0 and problems with the outdated browser core.
