4.1.0

[jpivarski]

The main new feature in this release is that Uproot 4 can now write ROOT files. It is no longer necessary to use Uproot 3 for anything: Uproot 4's capabilities exceed Uproot 3's in all ways that are currently known to me.

This was implemented in PRs #405, #406, #408, #409, #412, #414, #415, #416, #420, #421, and was described in Discussion #321. All the new functions are documented, and an overview is presented in the Getting Started Guide.
