1 Why we don't support IE 8
2 -------------------------
4 We've been living in 2007 for a while now, pretending that new browser features don't
5 exist because they aren't in IE8. You might not even know about some of these features,
6 or think they are only enabled by jQuery or underscore, simply because it hasn't
7 been an option to rely upon them.
9 Here is the list of features you don't have if you choose to support IE 8:
11 - HTML5 audio and video
17 - Multiple Backgrounds
18 - CSS3 Units (vh, vw, rem)
20 - Hardware accelerated graphics
21 - The DOMContentLoaded event
23 - Object.create, .seal, .freeze, .defineProperty
24 - Array.isArray, .indexOf, .every, .some, .forEach, .map, .filter, .reduce
25 - A modern JavaScript engine
26 - A real developer tools
27 - A consistent box model
32 It's true that IE 8 still holds a big chunk of the browsing population, but the reasons
33 why they can't update are dwindling. There are two big reasons for continuing IE 8 support.
37 Microsoft is dropping support for XP in April, organizations who want security updates will have to upgrade.
41 Chrome, Firefox and Opera all support XP. Nothing prevents users from upgrading, except the inertia of
42 organizations who still support IE 8.
46 We are skating towards where the puck will be, and we hope that as you decide to drop IE 8 support,
47 you choose to add Tether to the list of awesome things you can do.
