   9 Description
  10 ===========
  11
  12 The Symfony expression language is available for TypoScript since :issue:`85829` has been merged.
  13 Accordingly the classic TypoScript condition syntax has been marked as deprecated.
  14
  15 For detailed information about the new expression language see `#85829 <Feature-85829-ImplementSymfonyExpressionLanguageForTypoScriptConditions.rst>`_.

  18 Impact
  19 ======
  20
  21 Using the old condition syntax will trigger a PHP :php:`E_USER_DEPRECATED` error.
  22
  23 Also the combination of multiple condition blocks with :typoscript:`AND`, :typoscript:`OR`, :typoscript:`&&` and :typoscript:`||` has been
  24 marked as deprecated and will trigger a PHP :php:`E_USER_DEPRECATED` error.
  25
  26 If this is not possible yet to fully migrate to Symfony expression language, the feature flag :php:`[SYS][features][TypoScript.strictSyntax]` can be disabled via Settings -> Configure Installation-Wide Options or directly in :file:`LocalConfiguration.php`.
  27
  28
  29 Affected Installations
  30 ======================
  31
  32 TYPO3 installations with extensions which define conditions using the old syntax or setups which
  33 make use of the old condition syntax.
  34
  35
  36 Migration
  37 =========
  38
  39 The old conditions can be replaced with the new expression language.
