+# [v0.3.0](https://github.com/qri-io/dataset/compare/v0.2.0...v) (2021-05-04)
+
+This release of the `dataset` package includes one major change, adding a `Stats` component, as well as a few minor changes and a bunch of bug fixes that are listed below.
+
+## Stats component
+Introducing the `stats` component, a top-level component that provides the mechanics to quickly generate the stats using probabilistic structures. Unlike previous iterations of calculating stats, it is not bound to size/time limitations. We calculate and store different kinds of stats based on the content of the given column or fields. The different types as of this release are numeric, boolean, and string. We've moved the `qri/stats` package into `dataset` under the name `dsstats`.
+
+Take a look at our [spec](https://github.com/qri-io/specs/blob/master/content/subsystems/stats.md) for details on how stats are calculated.
+
+### Bug Fixes
