Deprecation: #86002 - TSFE constructor with no_cache argument¶
The 4th constructor argument of the PHP class
(a.k.a. "TSFE") was previously used to determine if the GET/POST parameter "no_cache" was set, which is
moved to a PSR-15 middleware now, making the argument obsolete. This argument is now set to "null" by default.
If anything other than the null value is given to the constructor method, a PHP
E_USER_DEPRECATED error is triggered.
TYPO3 installations with extensions that instantiate the PHP class manually and setting the 4th constructor argument.
Set the constructor argument to "null" when instantiating the class manually, use
to manually disable the caching mechanism.
