Since our support table for browsers [1] is wildly out of date, we
should come up with something better. Oliver generated some statistics
for us from the last 30 days from logs for text/html requests (see
attachment).
I think we could divide browsers into Grade A and Grade B categories,
similarly to desktop. Grade A would be full support, Grade B would be
basic support for reading (non-JS version). Two additional suggestions:
* Don't care about anything below < 0.1%
* Drop support for JS for any problematic browser with < 0.5% (mark them
as Grade B)
I think coming up with a generic metric like "support last N versions of
X and last M versions of Y" for all browsers would be hard because the
browser landscape changes pretty fast. I'd rather reevaluate our support
table every few months. For now, I propose the following:
Grade A:
* Mobile Safari 5-7 (that includes Chrome for iOS since it uses Safari's
engine)
* Android Browser 2.3+ (drop 2.3 to grade B as soon as it's < 0.5%)
* Chrome for Android 18+
* Firefox for Android, latest version (since it's not very popular, but
still a good browser)
* IE Mobile 9+ (drop 9 to grade B as soon as it's < 0.5%)
* Blackberry Webkit 7+
Grade B:
* lower versions of browsers in Grade A
* Opera Mini 4+
* NetFront 3+
* Ovi Browser 2+
* Nokia Browser 7+
When it comes to Grade B browsers, I don't think we should test on them
very regularly, but accept bugs that come from their users.
