======================================
|
|
Breaking: #98158 - Update to Symfony 6
|
|
======================================
|
|
|
|
See :issue:`98158`
|
|
|
|
Description
|
|
===========
|
|
|
|
TYPO3 Core now ships with Symfony 6.1. Previously TYPO3 v11 used Symfony Components
|
|
in version 5.4.
|
|
|
|
Impact
|
|
======
|
|
|
|
Some PHP code now might need to consider other types, especially regarding PHP
|
|
classes which might be extended or used directly, where types for arguments are used.
|
|
|
|
One example is that all CLI Commands (used in custom extensions) now need to define
|
|
an :php:`int` as return type of the :php:`execute()` method, otherwise the CLI
|
|
command will not be executed anymore.
|
|
|
|
Affected installations
|
|
======================
|
|
|
|
TYPO3 Installations with extensions making heavy use of Symfony components directly.
|
|
|
|
Migration
|
|
=========
|
|
|
|
Functionality such as the CLI Commands can already put in place for TYPO3 versions prior to
|
|
TYPO3 v12. It is recommended to use tools such as Rector to detect possible problems when
|
|
having extensions interacting with Symfony Components directly.
