New features and improvements will not appear in the Internet Explorer 11 browserEdit
As new standards emerge we have been very conservative about adopting them, because reliability of time-tested technology is fundamental to our mission and because it is not practical to run the new capabilities on older, cheaper or low-connectivity devices. Accessibility is a huge part of what we do and we tend to support browsers and systems well after most for-profit companies would have limited service, even when it means developing the same feature twice.
From time to time, and with heavy hearts, we have turned off full-support for browsers that have fallen below a certain usage percentage. This means that they can use the site, but it is a sub-optimal experience. Internet Explorer (or IE) is beginning to enter that realm. IE is a dying browser with shrinking usage. Microsoft has a new browser, Edge, which is based on Chromium, and Microsoft is actively encouraging users to move to Edge. We have already dropped full-support for all versions except for the last: IE11. Microsoft itself will be cutting off support for IE11 on its own services starting in mid-2021.
As mentioned above, looking at pure usage numbers, IE11 is above our subjective threshold for turning off support entirely. While it is 0.9% of our traffic worldwide, it is as much as 11.8% of our traffic in specific countries. Here are some examples where it is high: Pakistan (11.8%), Iran (6.4%), Japan (4.2%), South Korea (5.1%). We will be monitoring traffic-share for IE in those countries as we debate lowering IE support further.
What's to be doneEdit
Nothing by you for now. You might hear from community members that they cannot access a new tool you have sent them to. Or, in the future, a user in your community might see a banner letting them know that a feature they were using is no longer available. Before we drop support for an existing feature we will notify you with a briefer message using similar channels. We wanted to give you this warning so that if you encounter any feedback from your community or see a communication from us about this in the future, you have this context.
