 Hist is an analyst-friendly front-end for
 [boost-histogram](https://github.com/scikit-hep/boost-histogram), designed for
-Python 3.7+ (3.6 users get version 2.4). See [what's new](https://hist.readthedocs.io/en/latest/changelog.html).
+Python 3.8+ (3.6-3.7 users get older versions). See [what's new](https://hist.readthedocs.io/en/latest/changelog.html).
