The specs on solidus_braintree are deeply red. I've fixed the first error in this PR <https://github.com/solidusio/solidus_braintree/pull/155> but there are more errors after that. All I wanted is bump a dependency. <https://github.com/solidusio/solidus_braintree/pull/156>

All fixed, thanks to <@U0D4QPHT4> for reviews and support. <@U0ENVE2G1> we've bumped the `braintree` SDK dependency by a major version. Will try this out tomorrow in our app, if that works all fine this probably deserves a release.

It's been running fine for about a day and a half now, I think this can be released

I’ll try to take a proper look tomorrow

I think that a patch-level is ok for those changes, WDYT?

I would say minor version. There's a few breaking changes in the API of the Braintree gem that the extension does not touch, but I had to adapt how we integrated it a little
