Add a CHANGELOG

[shangxiao]

Would be awesome if a CHANGELOG was added to the repo so I can review updates before upgrading :)

Good idea! Right now it could be achieved easily by looking at the releases:

Hi @rapilabs . We're currently going through old issues that appear to have gone stale (ie. not updated in about the last 6 months) to try and clean up the issue tracker. If this is still important to you please comment and we'll re-open this.

Thanks!

@jkimbo @syrusakbary Can this be reopened?
