This update addresses the CVE-2026-109618 and CVE-2026-109619 security issues in PHP. It is recommended that you upgrade to this version as soon as possible.
The underlying frankenphp image has been updated thanks to the swift action from the frankenphp community.
It seems that the latest release of dunglas/frankenphp:1-php8.4 introduces an issue with Mercure. I've disabled that part of the configuration in Caddyfile to get the release out. I'm not familiar with Mercure, it seems that it deals with push notifications, or websockets, or something like that. I don't think the Habitat application needs it. In the long term I'll catch up to the latest changes in the Symfony Docker template repo.
