Automatically detect latest release

[Xaqron]

Due to constant change of version number it is bothering to update README file. Provided solution resolves this problem.

This is already automated by nvm's release process, so it's not actually bothersome.

I think having a version number in the command is helpful, to know what you're installing - and I think that curling to github's API is a bit of a brittle and convoluted approach (but I can't think of a better one)

[Xaqron]

Better approach would be having the latest script at a constant address as openvpn or docker do.
Every time I gonna install node via NVM I should check what is the latest release so I guessed maybe this is a common problem to other people.

That's by design; you should know what version of software you're installing and using, otherwise how can you know what features it has and what the API is?

[Xaqron]

Exactly. The problem is with design according to best practices. Why big companies like openvpn and docker provide a static address for the latest stable release?
Currently any script trying to install latest NVM should be updated manually or by some code like I have provided in PR. Example of static URLs:

• https://git.io/vpn
• https://get.docker.com

[ljharb]

Big companies do a lot of terrible things :-) the fact that a big company does something in no way automatically makes it a good practice.

I have http://latest.nvm.sh which redirects to https://github.com/creationix/nvm/releases/latest, but that's so you can get the manual install command you need from there, as a human.

I appreciate your work. Just tried to make life easier :)
