What is "v" for?

[rurounijones]

This is most likely a stupid question but I cannot figure out what the intended purpose of the "v" key is in the log output?

It is always 0 for me and looking through the code I see it is sometimes 0 or 1 in the tests.

Could you shed some light on what this key is for? 😄

@rurounijones The reason why I made Ougai is that I firstly wanted a Ruby JSON logger compatible with node-bunyan. That makes aggregating Ruby and Node.js JSON logs possible and they could be analyzed at the same. I guess that Bunyan logs have v field as the version of log format. Bunyan also have good viewer cli but it does not works logs without v field.
If you want simplier JSON formatter, please make your suitable formatter.
