 ### Changed
 
-  - Printing a DataFrame looks different
-    * Adds a row of `…` to indicate there are hidden rows. Includes a new option
-      `limit_dots: :bottom | :split` to specify how to do this.
-    * Drops the row separators except when composite dtypes are present.
-    * Allows you to pass through valid options to `TableRex.render!/2`. This
-      gives you a little more flexibility in case you don't like the defaults.
-  - `Explorer.DataFrame.print/1` now documents its default `:limit` of 5 rows
-  - `Explorer.DataFrame.concat_rows/1` has improved error messages
-  - Accessing a DataFrame with a range now raises if the range is out of bounds
