+# v0.9.0 (Tue May 25 2021)
+
+### Release Notes
+
+#### modernize Babel config ([#1721](https://github.com/system-ui/theme-ui/pull/1721))
+
+All Theme UI package became on average 34% lighter! 🪶 It's 9.5kB if you sum all of them!
+
+The trade-off is, Babel config has changed and it no longer supports Internet Explorer 11. 
+If you need to support legacy browsers, you can transpile node_modules (e.g. with [next-transpile-modules](https://github.com/martpie/next-transpile-modules)).
+
