It's here! It comes with tabs, file revisions, better spellchecker, better Markdown support and a lot more. It's also much faster and much more memory efficient.
Once we release a stable (non-beta) 4.0, we'll write a blog post that will explain the changes in more detail. We'll also release a new version of the website.
Meanwhile, please use the beta and let us know about any issues that you encounter! You can reach us at GitHub, Twitter or over email.
Thanks so much for the patience and for the support ❤️
