What FrankenPHP says
GitHub issue #2732 (comments dated 2026-10-21): a contributor says the v1.13.1 static binaries were rebuilt with PHP 8.5.12. A non-maintainer reported FrankenPHP Docker images were still on PHP 8.4.26/8.5.11 and official php:8.4.27-zts and php:8.5.12-zts images were published. No maintainer confirmed patched FrankenPHP Docker images or deb/rpm packages in the visible thread. The GitHub releases page lists v1.13.1 (16 Oct) as latest with no PHP 8.5.12 note.
1.13.1 binaries were already rebuilt with 8.5.12Update PHP
Docs list install methods to re-run: install script (curl https://frankenphp.dev/install.sh | sh), download a new static binary from GitHub releases, sudo dnf install frankenphp, sudo apt install frankenphp (after apt update), sudo apk add frankenphp, brew install dunglas/frankenphp/frankenphp. Docs show no docker pull instruction; verify the image's PHP version yourself.
Restart PHP
Worker docs: graceful restart of all workers via the Caddy admin API: curl -X POST http://localhost:2019/frankenphp/workers/restart (admin API must be enabled). Docs also describe --watch file-change restarts. Systemd installs: sudo systemctl start frankenphp is the only service command shown.
