- A [smarter](https://github.com/fugue-project/fugue/issues/304) way to determine default npartitions in Dask
- Support [even partitioning](https://github.com/fugue-project/fugue/issues/303) on Dask
- Add handling of [nested ArrayType](https://github.com/fugue-project/fugue/issues/308) on Spark
- Change to [plugin approach](https://github.com/fugue-project/fugue/issues/310) to avoid explicit import
- Fixed [Click version issue](https://github.com/fugue-project/fugue/issues/313)
- Added version caps for [antlr4-python3-runtime](https://github.com/fugue-project/fugue/issues/318) and [duckdb](https://github.com/fugue-project/fugue/issues/322) as they both released new versions with breaking changes.
