Use Dependabot to automatically keep dependencies up-to-date

[greysteil]

Quite a few dependencies in the mix.exs are out of date, including phoenix and stripity_stripe.

I built Dependabot to automatically create dependency update PRs when new versions are released. It's totally free for open source (and personal accounts) and I'd love to get more people using it on Elixir projects. Would you be up for giving it a try? Zero config required - will take you 60 seconds I promise.

The PRs it created on my fork are here.

Thank you for pointing your project out. We use greenkeeper to achieve something similar in our client project, so I see no reason not to do the same here.

We'd need to discuss it internally first, but this is certainly something we'll likely end up doing.

Awesome! 🎉 I used this project as the one for testing when I was developing Dependabot's Elixir support, so I'm super psyched to (hopefully) get you using it 😄.
