Joseph sent around this chart of Yahoo’s updated browser support chart.

I think Plaxo’s table is similar. The differences: We never supported Netscape—it should pretty much work when you fix Firefox bugs. We dropped IE 5.5 half a year ago instead of just recently—this is a big thing for Ajax programmers as IE 5.5 has some strange Javascript quirks. Safari 2.0 isn’t officially supported but non-stop-ship bugs are added and often fixed. We have no policy on Opera.

Anyone know why they are upgrading Opera support? Is it a mobile/PDA thing?
