If Homebrew was updated on Aug 10-11th 2016 and `brew update` always says `Already up-to-date.` you need to run: `cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update`.
**Please note by far the quickest way to get a new formula into Homebrew is to file a [Pull Request](https://github.com/Homebrew/homebrew-core/blob/master/CONTRIBUTING.md).**
