 ## [`master`](https://github.com/elastic/eui/tree/master)
 
+**Bug fixes**
+- `EuiInMemoryTable` and `EuiBasicTable` now pass unknown props through to their child ([#836](https://github.com/elastic/eui/pull/836)) 
+
 **Breaking changes**
 
 - Move `EuiBasicTable`'s `itemId` prop from `selection` to a top-level property ([#830](https://github.com/elastic/eui/pull/830))
