Release v4.0.0-rc

[danielmorell]

Description of the change

This updates the version so we can tag a release for v4.0.0-rc. I was initially thinking this would be beta2, but I don't know of any other changes that we are anticipating including in v4. Therefore, unless there are issues that need to be fixed in this version, we will follow this up shortly with the stable release.
