Yahoo! updated it’s Graded Browser Support yesterday. The changes involved dropping support for non-Safari browsers on Mac OS X 10.4 and non-Internet Explorer browsers on Windows 2000. Support for Internet Explorer 8 was added for Windows XP and Windows Vista.
This has given clout to support Internet Explorer 8 (which is in Release Candidate version now) in addition to versions 6 and 7. Here’s hoping Microsoft forces Internet Explorer 8 upgrades now that version targeting has been implemented.
