Version confusion

I just upgraded the punycode package from 2.1.0 to 2.3.0. Since I could not find a changelog or even a Git tag here, I backuped the 2.1.0 version from my node_modules folder and compared it to the version after the upgrade. They matched (empty diff)!

Then I found #122 and switched my installation to punycode.js. Now I'm seeing a difference (attached below), and importing punycode.js is obviously better than importing punycode/. But: node -pe "require('punycode.js').version" still outputs 2.1.0, taken from the source code:

punycode.js/punycode.js
