Fedify 2.1.0 is out!

The highlight of this release is onUnverifiedActivity(), a long-requested hook that lets you intercept inbound activities whose signatures couldn't be verified, instead of silently returning 401 and letting remote servers retry forever. Great for handling Delete activities from permanently gone actors.

Also new: full RFC 9421 Accept-Signature negotiation on both outbound and inbound paths, GoToSocial interoperability fixes, @fedify/mysql for MySQL/MariaDB backends, @fedify/astro for Astro integration, and fedify lookup --recurse for following reply chains.
