 - The `[name=...]`, `[time=...]` and `[color=...]` tags may now be used anywhere in the document and not just inside of blockquotes and lists.
 - The <i class="fa fa-picture-o"/> (add image) and <i class="fa fa-link"/> (add link) toolbar buttons, put selected links directly in the `()` instead of the `[]` part of the generated markdown
 - The help dialog has multiple tabs, and is a bit more organized.
+- Use KaTeX instead of MathJax. ([Why?](https://community.codimd.org/t/frequently-asked-questions/190))
