Create changelog based on pull requests

I saw that you have a changelog on your site and thought you might find the following useful. It's a tool that generates a changelog based on merged pull requests (with some additional benefits - accreditation, linking to the issue, and automation).

you can find the tool here https://github.com/lalitkapoor/github-changes.

To install it:
`npm install -g github-changes`

This was the command used to generate the changelog for dustjs:
`github-changes -o linkedin -r dustjs -d pulls -a -v`

Please let me know If you need any help adding it to your release script. If there are any improvements you'd like to see in this tool please feel free to open an issue :) Thanks!
