With recent security-related changes, the escaping behaviour of ViewHelper arguments in Fluid has changed in a possibly breaking way. In case you encounter issues with this new behavior in a ViewHelper you can't fix, please add the following line into your typo3conf/AdditionalConfiguration.php for each affected ViewHelper:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['fluid']['security']['disableNewEscapingBehavior'][\ACME\Extension\ViewHelpers\MyViewHelper::class] = true;

It is possible to disable the new escaping behavior globally as well, however, this is not recommended. To do so, please add the following line into your typo3conf/AdditionalConfiguration.php:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['fluid']['security']['disableNewEscapingBehavior'] = true;

The usual upgrading procedure applies. No database updates are necessary. It might be required to clear all caches; the "important actions" section in the TYPO3 Install Tool offers the accordant possibility to do so.
