MycorrhizaWiki 0.5 is the first released Mycorrhiza version. Date: 2020-06-30. Next: ../0.7
This version is dramatically different from all further releases. First of all, Markdown is used rather than Mycomarkup. It's not like u/bouncepaw liked Markdown; he just didn't want to bother himself with implementing the markup language for now.
Second, a handmade revision system is used along with a complicated folder structure. It was quite fun but no one liked it; also, it was hard to follow by hand.
Third, themes were supported! In fact, they were usual hyphae, you could just edit HTML in your browser. It turned out to be a bad idea.
Note how the interface is different from the ../teaser screenshot.
