K2 has released a statement announcing the immediate end to security updates or technical support for Microsoft Internet Explorer versions earlier than IE 11.
On Tuesday, January 12th, Microsoft ends support for Internet Explorer 8, 9, and 10. The end of support means that these older versions of Internet Explorer will no longer receive security updates or technical support.
As such, K2 will also no longer release fixes or patches for these older versions of Internet Explorer. You may continue using the older browser versions with K2 products, but if any issues arise K2 will not release fixes or patches for unsupported browser versions. You will be required to upgrade to a supported version or use a different supported browser.
