Breaking: #96968 - Hook “headerNoCache” removed¶
See Issue #96968
Description¶
The previous TYPO3 Hook “headerNoCache” registered via
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['headerNoCache']
has been removed in favor of a new PSR-14 Event
ShouldUseCachedPageDataIfAvailableEvent
.
Impact¶
Hooks in third-party extensions will not be executed anymore.
Affected Installations¶
TYPO3 installations with custom extensions using this hook.
Migration¶
Register a new PSR-14 event listener for ShouldUseCachedPageDataIfAvailableEvent
in the extensions’ Services.yaml to keep TYPO3 v12+ compatibility.
Extensions can then provide compatibility with TYPO3 v11 and TYPO3 v12 at the same time.
