Symfony 4

Automate everything

Symfony 5 integrates seamlessly with Symfony Flex to automate the most common tasks performed by applications. Forget about enabling bundles or creating their initial config: Symfony Flex does that for you.

The automation leverages the Symfony Recipes, which contain instructions to integrate hundreds of third-party bundles and packages into Symfony applications.

New Components

Symfony 5 includes a new String component that provides an object-oriented API to work with UTF-8 Strings using bytes, code points and grapheme clusters. Need to create a "slug", trim content, replace text or do anything else on a string that could contain any characters? Do it quickly & safely with the String component.

Symfony 5 also includes a new Notifier component to create and send all kinds of notifications via SMS, email and chat services like Slack and Telegram.

To securely store "secrets", Symfony 5 has a secrets management system where sensitive production values can be safely encrypted and stored in version control. This works seamlessly with environment variables, allowing a consistent experience whether a value is "secret" or not.
