Question of dgl build from source

I have downloaded the updatest source files from GitHub, and follow the guide from https://docs.dgl.ai/install/index.html#install-from-source

After python setup.py install, I find the dgl version is 0.4, It seems a little strange, should the version be 0.4.2?

OS: osx mojave 10.14

Have you installed an older version of DGL before? If so, you will need to uninstall dgl first.
