+## Dropping support for Internet Explorer 11{#ie11eol}
+
+Silverstripe CMS 4.9.0 is the last release of Silverstripe CMS that supports Internet Explorer 11. Silverstripe CMS 4.10.0 will not support Internet Explorer 11.
+
+[Microsoft has announced the end-of-life for Internet Explorer 11](https://blogs.windows.com/windowsexperience/2021/05/19/the-future-of-internet-explorer-on-windows-10-is-in-microsoft-edge/) on June 15, 2022. It has already dropped Internet Explorer support in many other products including Microsoft Teams and Microsoft 365. In this context, any development time dedicated to maintianing Internet Explorer support could be better use improving other areas of Silverstripe CMS.
+
+While the Silverstripe CMS UI might not allow content authors to manage content in Internet Explorer, this does not preclude Silverstripe CMS project from outputting an a frontend site that is compatible with Internet Explorer.
