Notes

We're closing in on a stable release, and as a final step before we hopefully move on to a stable release next week, we have one last update for you with just two bug fixes for two more possible crashes in the editor. As ever as we approach a stable release we try to reduce the number of changes to ensure there are no unexpected last-minute problems, but fear not - we're still working hard behind-the-scenes on more additions, changes and improvements for the next release cycle. Happy testing!
