Key changes include an AI-powered spam detection chapter using Symfony AI with LLM integration (OpenAI, Anthropic, Gemini, Mistral, Ollama), replacement of Doctrine fixtures with Zenstruck Foundry object factories for testing, dropping Webpack Encore and Node.js in favor of AssetMapper with importmaps, replacing a Preact SPA with Symfony UX Turbo for SPA-like navigation, and migrating the cron chapter to the Symfony Scheduler component. Deployment now targets Upsun (next-gen Platform.sh). The book is free online at symfony.com/book, available in five languages, and validated by automated tooling that builds and deploys the guestbook commit by commit. ## Full article daily.dev links to this article rather than hosting it.
