Microsoft this week released this final version of Internet Explorer 4.0 for Windows 3.1 and Windows NT 3.51, bringing these operating systems into the current-generation of Web browsing features.

"We are pleased to offer our customers the ease of use and security features already available in Internet Explorer 4.0 for Windows 95," said Yusuf Mehdi, director of marketing in the application and Internet client group at Microsoft. "With unique features such as the acclaimed Explorer Bars, standards-based Dynamic HTML, Active Channel content and Security Zones, Internet Explorer 4.0 is a great upgrade for anyone using Windows 3.1."

Internet Explorer 4.0 for Windows 3.1 also include rich HTML mail with the Outlook Express e-mail client, which also supports multiple email accounts and customized stationery. Unlike its Windows 95/NT relation, however, Outlook Express for Windows 3.1 does not included integrated newsgroup features.

The new browser also supports Active Channel content and webcasting support but not Active Destktop. It does include support for the latest HTML standards from the World Wide Web consortium (W3C) such as Dynamic HTML support, ECMA Script (JavaScript), Channel Definition Format (CDF), LDAP, IMAP and Java.

Internet Explorer 4.0 for Windows 3.1 and Windows NT 3.51 will be available in 20 languages other than English over the next 90 days. It can be downloaded free of charge from Microsoft's IE 4.0 Web site
