Around August 24th 2015 users of IE 8 will start seeing a alert bar inside their map urging them to update their browser.
Why is this happening?
IE8 is an older browser which does not have many of the capabilities of modern browsers and is no longer supported by many websites, including Google Apps and Google Analytics. Microsoft also announced in 2014 that they will no longer support IE8 from January 2016 for desktop operating systems. In addition, running the latest, supported browsers provides an optimal and most secure experience for users, so we recommend that all users upgrade to more modern browsers.
