Drop the default export?

[ctavan]

In [email protected] the Version 4 algorithm was exported as a default:

const uuid = require('uuid');
uuid(); // -> "2b0d20b0-6462-4738-abe6-413512e9fbf2"

In the current master this is no longer the case:

const uuid = require('uuid');
uuid(); // -> Uncaught TypeError: uuid is not a function
uuid.v4() // -> "ea58b65b-80c4-44c6-b482-6714c78ac43e"

The minimum we should probably do is describe this in the README and in the CHANGELOG.

I could also try to use the data from https://github.com/tc39/proposal-uuid/tree/master/analysis in order to try to figure out how much of a breakage removing the default export would be?!

What do you think about this breaking change @broofa?

Finally, an actual breaking change! ;-) (I'm fine with this since we've been actively discouraging people from using a default export since v3.)

Cool! I only found out about this breaking change now while writing the TypeScript types, so it looks like you did a great job at discouraging it's use 😂!

I will still add a note to the upgrading section in the readme though and will make sure that this breaking change appears in the CHANGELOG.

I would recommend leaving a human readable exception in place for user experience.
