About Sulu
Sulu adds AI disclosure fields to media, shipped to both supported lines the same minute
Sulu is a Symfony-based CMS for developer-built sites, released as a synchronised pair: every 3.0.x patch ships within a minute or two of the matching 2.6.x patch, carrying largely the same pull requests. The 3.0.9 / 2.6.26 pair is the most substantive in months. Media assets gain Origin and AI Disclosure information, delivered as a doctrine migration with new columns and an updated form metadata snapshot, and the AI platform integration now reports a reason when it turns a request down. Two-factor setup adds an authenticator app (TOTP) flow and a Google Authenticator method, and a deprecation batch retires AbstractRestController, RestControllerTrait, ApiWrapper and the persistence component repositories and traits.
