Comment (by nacin):
Based on a sample of data sent to http://api.wordpress.org/core/browse-
happy/1.0/, collected over the last few days —
* IE is 14.1%
* IE7 is 2.0%
* IE8 is 4.7%
* IE9 is 6.1%
My thoughts: We haven't done a whole lot to make IE7 work in recent
versions. In 3.5, the stuff we did for IE8 already got us 90% of the way
there. In 3.4, we had the customizer require postMessage, and thus didn't
support it for IE7. In 3.6, more work will be directly in the admin
(versus a separate experience, like the media library and customizer), but
once you do IE8, we're usually pretty close to IE7.
Our level of support for IE7 has been pretty simple: just make sure it
degrades in a somewhat graceful manner. If gradients are busted, that's
fine. Lack of support for alpha transparency doesn't bother us. Even just
declining to show a feature in IE7 is fine. But it doesn't take much to
ensure that we have no terribly broken interfaces with boxes floating off
the screen. How much we actually fix up in IE7 should be a feature-by-
feature call, and probably only after we've done the IE8 support.
We used to group IE7 with IE6, but it's also fair to group it with IE8.
Both are fairly old browsers that have very similar quirks. It's why
jQuery 2.0 is dropping (sans-shim) IE 6, 7, and 8, rather than just IE7
and older. Also, Windows XP is EOL come 2014, which kills the operating
system base for IE8 and below, so we'll probably start to see enough shift
by 2014 or 2015 to pretty much drop IE8 and below.
