mathstodon.xyz is now running Mastodon v2.9.2!
The big new feature this time is the single-column layout, which looks more like standard Twitter. It's the default layout for new users. Existing users can switch to it on the preferences page.
Full release notes: github.com/tootsuite/mastodon/

Thank you for updating! I like it!

A Mastodon instance for maths people. The kind of people who make $$\pi z^2 \times a$$ jokes. Use $$ and $$ for inline LaTeX, and $ and $ for display mode.
