+**Deprecations**
+
+- Replaced `$breakpoints` in favor of better named `$euiBreakpoints` ([#909](https://github.com/elastic/eui/pull/909))
+- Replaced the following mixin `screenXSmall()`, `screenSmall()`, `screenMedium()`, `screenLarge()`, `screenSmallMediumLarge()` in favor of a single `euiBreakpoint()`. ([#909](https://github.com/elastic/eui/pull/909))
