4.0.1 - Replacement for 4.0.0 which can't be downloaded from PyPI
This is a doc-only update to replace 4.0.0 which I removed from PyPI (pip). This should be 100% compatible with 4.0.0.
I was attempting to replace the source tarball for 4.0.0 but that is apparently not allowed. It would have been nice to know that before it let me delete it ;)
You should upgrade to 4.0.2, however, for some important bug fixes.
