When creating a site with MetaMask, you also want that other users who do not have MetaMask can use this site. To do this, you want to use the same library MetaMask uses - which is 0.20.3 currently.
I cannot find 0.20.3. I checked GitHub releases. Version 1.0.0-beta is up, and older versions do not hit 0.20.3
Where can I find this web3 version?
