+API changes:
+* `overlap`: In previous versions, output coordinate columns were always converted to Pandas "nullable" `Int64` dtype before returning. In the interest of flexibility, memory efficiency, and least surprise, the coordinate columns returned in the output dataframe now preserve dtype from the input dataframes, following native type casting rules if missing data are introduced. We introduce the `ensure_nullable` argument to force Pandas nullable dtypes in the output coordinates. See the [docs](https://bioframe.readthedocs.io/en/latest/api-intervalops.html#bioframe.ops.overlap) for more details. (#178)
+
+Bug fixes:
+* Fixed `coverage` with custom `cols1` (#170)
+
+Documentation:
+* Added contributing guidelines and NumFOCUS affiliation.
+* Updated README and added CITATION.cff file.
+* Updated performance benchmarks.
