release tag must equal version in composer.json

Hi @paustian

You must update the version string in composer.json before tagging a new release. The current version string is "4.0.0" but the tag is "4.0.1"

so, to proceed, you should change it to "4.0.2" and then tag/release "4.0.2"

you'll need to branch now in order to do this since I made some changes in master that are intended for version 5
