Updated for Gatsby 5 and gatsby-plugin-image
Quite a lot has changed about Gatsby since I wrote this plugin, not least the entire way that images are handled, it seems! As a result, I've rewritten or refactored much of this plugin, and it now behaves nicely with GatsbyImage and so on.
As a result, these changes are very breaking - not much will work if you install this over the top of a v1.x without changing your implementation. On the bright side, the implementation is now much neater and better, as a result of the GatsbyImage functionality that has been added.
Some highlights in the CHANGELOG.
