On January 12th, 2016 IE 8, 9 and 10 are reaching the end of their life. This means that Microsoft will not longer support those browsers versions after this date and those 3 IE versions won’t be eligible to receive any updates after that.
IE 11 is the last version of Internet Explorer and will continue to receive technical and security updates on Windows 7, Windows 8.1 and Windows 10. Microsoft will encourage users to upgrade by releasing an upgrade notification.
While this is good news for developers IE 8, 9 and 10 are still popular browser versions and will most likely be continued to be used by many users in the coming months. Based on the December 2015 stats released by Netmarketshare IE 8, 9 and 10 equal 20% of the browsers usage.
Most of the websites we test are still supported in those browser versions, although web applications are not optimized for IE 8. As far as IE 9 and IE 10, they will likely continue to appear in user statistics for a while. Digital Agencies designing and building websites will probably continue to support these browsers if users continue using them after support is dropped. It will be interesting to see future user statistics and how long those browsers persist in the market. Hopefully not as long as IE 6 did during its time.
