Great news!
Have we considered dropping IE 10 to grade C given Microsoft ended support
for it more than a year ago and it seems to be as low as IE 9 (only a 0.24%
*[1]*)?
Also, a question. Does this mean we don't need to explicitly list the
*es5-shim* any more?
Thanks for the great work.

Hi all,
Starting in April 2017, MediaWiki will end Grade A support for browsers
that
do not implement ES5 JavaScript. [1] This affects Internet Explorer 9 users
and others using very old mobile browsers. [2] Users with these browsers
will
still be able to browse and contribute to the projects. Enhanced features
will
become unavailable. For example, the enhanced edit toolbar will not appear,
and notification buttons will take you to a page rather than open a
pop-out.
This change will affect roughly 0.59% of page views to Wikimedia wikis (as
of
February 2017 [2]). Internet Explorer 9 (0.27%), mobile users on iOS 4
(Mobile
Safari 5 — 0.02% of traffic), and Android 2 (0.1%). For comparison, 0.3% of
traffic comes from Internet Explorer 8 (JavaScript-less since January
2016).
Providing JavaScript for IE 9 and other ES3 browsers adds a significant
maintenance burden. It also hinders site speed for all users. Microsoft
ended
its official support for Internet Explorer 9 and 10 in January 2016. [4]
Users unable to upgrade from IE 9 or Android 2 will have a faster
experience
going forward, based on well-tested and more stable code.
This change will land in the development branch used on all Wikimedia wikis
this April, to be released as part of MediaWiki 1.29 around May 2017.
Please help carry this message into your communities.
(Tech News has announced this change as well)
Yours,
-- Timo
