Two new Trellis releases are out — v1.28.0 and v1.29.0. The highlights are HTTP/3 support (props @strarsis), opt-in WordPress runtime hardening (separate PHP-FPM identity from the deploy user), Redis PHP session storage, and Ansible 2.19 compatibility.
There are also some important fixes for FastCGI cache (redirect loops and stale content on unpublish) and a security fix for HTTP response splitting in multisite subdirectory setups.
