|
|
|
|
===============================================
|
|
Breaking: #96968 - Hook "headerNoCache" removed
|
|
===============================================
|
|
|
|
See :issue:`96968`
|
|
|
|
Description
|
|
===========
|
|
|
|
The previous TYPO3 Hook "headerNoCache" registered via
|
|
:php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['headerNoCache']`
|
|
has been removed in favor of a new PSR-14 event
|
|
:php:`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
|
|
:ref:`ShouldUseCachedPageDataIfAvailableEvent <feature-96968-1663513232>`
|
|
in the extension's :file:`Services.yaml` to keep TYPO3 v12+ compatibility.
|
|
|
|
Extensions can then provide compatibility with TYPO3 v11 and TYPO3 v12 at
|
|
the same time.
