A number of Microsoft enthusiasts this week received invitations to a "limited technical beta program" for Internet Explorer (IE) 8 Beta 1. According to the invitation, Microsoft is planning to make IE 8 Beta 1 available to the general public, as well. But before that happens, an invitation-only tet program will be conducted. The invitation describes IE 8 Beta 1 being focused on developers. Microsoft officials have said they plan to show off IE 8 at Microsoft's Mix '08 conference in early March in Las Vegas. Officials also have said they are planning to add a developer-selectable "super-standards" mode to IE 8 that would enable the browser to qualify as more standards-compliant. Microsoft still has not offered a final-delivery target date for IE 8. Microsoft released IE 7 in 2006. Microsoft officials have said they are shooting to deliver more frequent, regular builds of IE.
