 ### Enhancements
 - Added `target_tables` attribute to `DynamicTable` to allow users to specify the target table of any predefined
 `DynamicTableRegion` columns of a `DynamicTable` subclass. @rly [#971](https://github.com/hdmf-dev/hdmf/pull/971)
+- Updated `TermSet` to include `_repr_html_` for easy to read notebook representation. @mavaylon1 [967](https://github.com/hdmf-dev/hdmf/pull/967)
 
 ### Bug fixes
 - Updated custom class generation to handle specs with fixed values and required names. @rly [#800](https://github.com/hdmf-dev/hdmf/pull/800)
