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 test 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.
