I have a git (and Github) repo with a `master` branch, a `development` branch and several feature branches. Each of the feature branches have been branched off `development` and subsequently merged into `development`. 

I'd now like to "promote" `development` to `master`. I don't want to merge these two branches because conflicts may arise. Essentially, `development` is "production ready" and I'd like for `master` to reflect the current state of `development`. How can I do this?
