Weird, it already does at my work computer since a month which aren't exactly first to get the latest updates and definitely don't get prerelease software. I wonder how all that works.

(Update: Ah, title is a little misleading. This update doesn't introduce Markdown, it adds support for nested Markdown lists etc.)

Personally, I think they should've kept Notepad as-is and reincarnated WordPad instead, rewriting it and giving it Markdown instead of RTF. It already had the basic formatting interface and all. It would've been a pretty smooth transition.

The problem is that Markdown supports quite a bit, even tables, which lends to feature creep. It was already more sluggish without any of this due to moving Notepad to WinUI.
