Downside is that many topics that were written before the update show some weird behaviour now. For example headings in the form ##Heading don’t render anymore. We have to change that to ## Heading (mind the space between ## and Heading).
If you find broken formatting in a Wiki, I invite you to change the headings and anything else you find. Let’s make the forum a well-formatted place again!
You can use a dash or an asterisk and start the first item with zero, one or two spaces before the symbol. The only thing that changed is that you now need more spaces to make sub-points.
