The last version of Internet Explorer, version 11, was released on October 17, 2013. This is a very long time ago when taking into account the rapid development of web technologies. These days it is often difficult and time consuming to get modern technologies to work well in this old browser. More and more frameworks are dropping support, and even Microsoft themselves has announced that they will fully drop support for IE in their own services in 2021.
Consequently, we have decided to not include support for IE in the Design Library website.
Alerting the user have never been this clear!
After a long period of testing, we have now updated the Alert ribbon component. Feedback from user tests and usage from several channels, showed us that purple as a colour was too loud.
We also saw that the description in Design Library generally was too confusing with information split between a component and a pattern. It's focused on the component now. And finally, there was a design synk between Bootstrap and Design Library which generated sensible updates for both.

Let me know if anything is unclear. Thank you!
