Just updating the 1.8.7-compatible dependencies. Especially Liquid 2.6.0 comes with several fixes: https://github.com/Shopify/liquid/blob/master/History.md#260--2013-11-25--branch-26-stable
This breaks some things I think, so we'll need to add tests for those. I'll look through the history and write some more tests in a couple days.
Since master is 2.0 now, can we just 🔥 this pull request in favor of a more comprehensive update to our dependencies?
