Twenty years ago this past February, @KevinMarks.com (@KevinMarks@xoxo.zone) and I introduced #microformats in a conference presentation.

Aside: This is a summary of a longer post from ~200 days ago¹, which #Mastodon readers never got due to a Mastodon #federation bug (instances returned 202 for post inbox delivery, but did not show post to followers or on local profiles, details in https://tantek.com/t5Yo1).

I wrote a retrospective last year: https://tantek.com/2023/047/t1/nineteen-years-microformats

Since then, here are the top three updates & interesting developments in microformats:

1. Growing rel=me adoption for distributed verification (✅ in Mastodon etc.)
 * Wikipedia, Threads, omg.lol support
2. A proposal to merge #microformats2 h-review into h-entry, since reviews are in practice (e.g. on the #indieweb) always entries with a bit more information.
3. #metaformats adoptions, implementations, and iteration
