@steakhal before I merge - have a look, I squashed it and had to fix some issues. But I think it's fine now, let me know otherwise.

For future reference, when updating a branch for the release branch we can't use the automatic squash and rebase workflow of github, so it's better if you squash and rebase yourself otherwise I will have to do that manually.
